Water filter description
FIELD OF THE INVENTION
[0001] The present invention relates to an improved water filter
vacuum cleaner and particularly to a water filter vacuum cleaner
for drawing external suction articles and trapping the suction articles
and collecting dusts through internal oscillation moisture generated
a suction airflow.
BACKGROUND OF THE INVENTION
[0002] Nowadays the vacuum cleaner has almost become an indispensable
household cleaning appliance. It generally includes a vacuum body
to generate a strong suction airflow and a housing compartment in
the vacuum body. The vacuum body is connected to a hollow hose which
has a distal end connecting to a suction head. When the suction
body generates the suction airflow, suction articles are drawn through
the suction head and the hose into the housing compartment. After
vacuum operation has been finished, the housing compartment may
be detached from the vacuum body for clearing the suction articles
drawn inside.
[0003] The present vacuum cleaners can be divided into a dry vacuum
cleaner and a wet vacuum cleaner. Both are designed to generate
a strong suction airflow. Due to the strong airflow, the conventional
dry vacuum cleaner often cannot trap small articles (such as fine
dusts or debris) in the housing compartment. The fine dusts are
dispelled with the discharged airflow to the exterior. Dust collecting
function becomes not effective. Referring to FIG. 1 the wet vacuum
cleaner differs from the dry vacuum cleaner in the design of the
housing compartment. As shown in the drawing, the housing compartment
contains filter water. And an airflow duct is extended from interior
of the housing compartment to couple with a connection tube. When
the suction articles are drawn into the housing compartment, the
suction airflow generates oscillating water spray in the housing
compartment to bind and trap the suction articles. The rest clean
air is discharged outside. Hence it is more effective than the dry
vacuum cleaner and can overcome the disadvantage of failing to trap
the small suction articles occurred to the dry vacuum cleaner.
[0004] However, as shown in FIG. 1 the conventional wet vacuum
cleaner that provides water filter function mostly is quite bulky.
This is because the housing compartment has only one filer room.
When the contained water is not enough, suction airflow tends to
splash the water excessively and result in not desirable binding
with the suction articles. Although some vacuum cleaners have a
partition located in the housing compartment, the partition merely
aims to prevent the water from being dispelled with the discharged
airflow and causing dysfunction of the vacuum cleaner. If the water
content is too much, the filter room is too large and oscillating
water spray cannot be generated as desired, and the strong suction
airflow tends to carry a portion of the filter water away outside
the housing compartment. As a result, the filter water splashes
outside and causes environmental pollution. And an extra effort
is needed to wipe the spilled water. It is troublesome.
SUMMARY OF THE INVENTION
[0005] Therefore the primary object of the present invention is
to solve the aforesaid disadvantages. The present invention employs
a converged filter approach to generate oscillating moisture and
trap suction articles. It includes a vacuum body which contains
a dust chamber and a dust collection assembly in the dust chamber
that contains filter water. The dust collection assembly consists
of a dust collection seat and a upper cap. The interior of the dust
collection seat is divided by a partition into a filter chamber
and an airflow chamber that communicate with each other. The airflow
chamber has an airflow duct connecting to the filter chamber. The
vacuum body has a suction assembly to generate a suction airflow
to draw suction articles into the filter chamber through the airflow
duct, and the suction airflow also generates oscillation moisture
to trap the suction articles. Then the clean suction airflow is
discharged through the upper cap and a guiding member communicating
with the upper cap and the suction assembly to the suction assembly
to form an output airflow to be discharged through an air outlet.
Such a structure can effectively filter the suction articles and
shrink the size of the water filter vacuum cleaner.
[0006] The foregoing, as well as additional objects, features and
advantages of the invention will be more readily apparent from the
following detailed description, which proceeds with reference to
the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0015] Please referring to FIGS. 2 and 3 the water filter wet
vacuum cleaner according to the present invention includes a vacuum
body 10 which is openable. The vacuum body 10 includes a suction
assembly 11 capable of generating a suction airflow and an output
airflow and an air outlet 12 communicating with the suction assembly
11 to discharge the output airflow. The suction assembly 11 includes
a motor and fan like a conventional technique. The vacuum body 10
has a dust chamber 13 in the interior and a suction port 14 communicating
with the dust chamber 13 and connecting to an external suction means.
Referring to FIG. 6 the external suction means includes a hose
15 connecting to the suction port 14 and a suction head 17 connecting
to other end of the hose 15. The hose 15 is connected to a dust
collector 16. The dust collector 16 includes a housing chamber 161
made from a transparent or translucent material, a suction duct
162 a housing seat 160 connecting to the suction head 17 a barrier
section 165 and a coupling hub 164 of a suction bore 166 that connect
to the housing seat 160 corresponding to the suction duct 162 and
a base dock 167 connecting to the coupling hub 164 that has an airflow
passage 168. The housing seat 160 and the coupling hub 164 have
respectively a fastening bore 163 and a latch section 1641 that
mate each other. The base dock 167 further has a handle 169 for
user grasping during vacuuming.
[0016] Referring to FIGS. 4 and 5 in the dust chamber 13 there
are a guiding member 20 and a dust collection assembly 30. The guiding
member 20 has a first air passage which includes a first airflow
port 22 on one end connecting to the suction assembly 11 and a second
airflow port 23 on another end. The guiding member 20 further has
a filter 24 in the first airflow passage between the first airflow
port 22 and the second airflow port 23. The duct collection assembly
30 includes a duct collection seat 31 for holding filter water and
a upper cap 32 coupling on the duct collection seat 31. The upper
cap 32 consists of two corresponding half boxes that are coupled
together. The upper cap 32 further has a second airflow passage
which has a third airflow port 321 on one end connecting to the
second airflow port 23 and a fourth airflow port 322 connecting
to the suction port 14. The dust collection seat 31 is divided into
a filter chamber 311 and an airflow chamber 312 by a partition 318.
The airflow chamber 312 has a hollow air duct 313 which has one
end connecting to the fourth airflow port 322 and another end communicating
with the filter chamber 311. Referring to FIG. 7 The airflow duct
313 and the filter chamber 311 are communicated through an airflow
seat 314. The filter chamber 311 contains a filter assembly which
consists of a base 315 which has filter pores 3151 a filter mesh
316 located on the base 315 and a lid 317 containing air vents 3171
to cover the base 315. The upper cap 32 further includes a guarding
member 33 on the third airflow port 321 that has a hollow housing
331 to hold an inhibitor 332 to serve as a counter weight to close
the third airflow port 321. The guarding member 33 aims to close
the third airflow port 321 through the inhibitor 332 lifted by the
suction of the suction airflow when the water in the filter chamber
311 exceeds the upper limit and the suction airflow cannot generate
desired oscillation moisture to form a smooth airflow. Then users
are alerted to close immediately to prevent the water from being
discharged with the airflow caused by excessive suction airflow
that occurred to the conventional wet vacuum cleaner.
[0017] Referring to FIG. 8 when the suction assembly 11 of the
vacuum body 10 generates a suction airflow, and suction articles
are sucked in through the suction head 17 into the dust collector
16 the barrier section 165 in the dust collector 16 blocks larger
suction articles so that they drop into the housing chamber 161
while the smaller suction articles are drawn through the suction
bore 166 airflow passage 168 and hose 15 into the vacuum body 10.
The dust collector 16 of the invention aims to prevent the larger
suction articles from entering the vacuum body 10 that might cause
clogging. It also makes clearing of the larger suction articles
such as small screws, small nails, thumbtacks or glass debris easier.
[0018] Referring to FIG. 9 when the suction articles enter the
dust collection assembly 30 through the suction port 14 as the
suction airflow has already generated oscillating moisture in the
filter chamber 311 the airflow duct 313 and the airflow seat 314
also have oscillating moisture, so that small suction articles such
as dusts are bond to the oscillating moisture in the airflow duct
313 airflow seat 314 and filter chamber 311 and trapped. If there
is a small amount of the suction articles that do not bind to the
oscillating moisture, they are filtered by the filter and also are
trapped. Hence the clean suction air passes from the airflow chamber
312 through the third airflow port 321 to the second airflow port
23 and enters the first airflow passage. Meanwhile, the filter 24
in the guiding member 20 further filters the air so that the air
passing through the first air passage and the first airflow port
22 and the suction assembly 11 becomes the clean output airflow
to be discharged through the air outlet 12.

set forth for the purpose of disclosure, modifications of the disclosed
embodiment of the invention as well as other embodiments thereof
may occur to those skilled in the art. Accordingly, the appended
claims are intended to cover all embodiments which do not depart
