ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to cleaning device, and particularly to a bacteria removing cleaner. The washing time can be controlled effectively; moreover, the bacteria removing cleaner is capable of being assembled to a stool rapidly and quickly. Thereby, the lifetime is prolonged.
BACKGROUND OF THE INVENTION
In the prior art, the amount of flushing water is controlled by a computer device, but this design can not meet the requirement of everybody and thus it is inconvenient for many users. Moreover, the price and damage rate are high. Therefore, it can not be accepted by everybody.
In U.S. Pat. No. 6,006,372, “cleaner”, assigned by the applicant of the present invention, disclosed a cleaner which has a main body
1
and a nozzle unit
2
and a plurality of conduits
3
.
The main body
1
is formed by locking a control valve
11
and a lower receiving body
12
. A control valve
11
has a control handle
13
. Two lateral bottoms of the control handle
13
are formed with a large arc
131
and a small arc
132
. A valve rod
14
is formed at an inner side. The valve rod
14
is enveloped by a compressing spring
141
. An outer side thereof is enclosed by a valve cover
15
. Moreover, the lower receiving body
12
is formed with an outer casing
121
and an inner wall
122
. A plurality of pressure balance holes
123
are formed on the inner wall
122
. Water inlet channels
16
,
17
are installed at the proper positions of the casing
121
. A retaining plate
18
is protruded from another side and the bottom thereof is installed with a water draining channel
19
. The upper end of the water draining channel
19
has a valve cover
15
. When the control handle
13
is pressed downwards so that the valve rod
14
and the valve cover
15
are pulled upwards, the water draining channel
19
can be opened for draining water. After the control handle
13
returns and the valve rod
14
is put down. Thereby, the valve cover
15
closes the water drain channel
19
so as to isolate the water from flowing through the water drain channel
19
.
The nozzle unit
2
has a separable retaining pad
21
. The retaining pad
21
may be an upper pad
211
or a lower pad
212
with the type of the stool by sticky or screw
213
. Besides, the top end of the retaining pad
21
is installed with a nozzle conduit
22
. One end of the nozzle conduit
22
is installed with a tube joint
23
. Another end thereof is installed with a nozzle
24
. The center of the nozzle
24
is installed with straight jetting holes
241
, and the outer side of the straight jetting holes
241
has a plurality of inclined jetting holes
242
. When water flows to the holes
241
and
242
, the two kinds of water beams will interact so as to generate spiral water beams C so as to have preferred flushing effect. Referring to
FIGS. 1
to
4
of the attachment, the user can press the large arc
131
or the small arc
132
(the water can be flushed continuously). When the control handle
13
is pressed and after the valve rod
14
and valve cover
15
are pulled upwards, clean water will enter, into the casing
121
from the water inlet channels
16
and
17
. To prevent the valve cover
15
made of silicon rubber from being flushed by water, when water flows through the pressure balance holes in the inner wall
122
of the casing
121
, the water will retain a constant water pressure. Then, the water flow is guided to the nozzle unit
2
through the water draining channel
19
(
FIG. 6
of the attachment). When water flow to the holes
241
and
242
, the two kinds of water beams will interact so as to generate spiral water beams C so as to have preferred flushing effect.
Furthermore, if it is to be closed. It is only necessary to return the handle
13
to the original position. By the ejecting force of the compressible spring
141
, the valve rod
14
will resist a downward force. Meanwhile, the valve cover
15
will close the water draining channel
19
. Therefore, water is isolated not to flow through the water draining channel (see (referring to
FIGS. 1
,
2
and
3
).
In above clean structure, since the valve rod
14
is axially connected to the control handle
13
and the valve rod
14
passes through the valve cover
11
. Thereby, the valve rod
14
below the valve cover
111
must be installed with a compressible spring
141
, and then the valve cover
15
encloses the outer side of the valve rod. Since the valve cover
15
is made of silicone rubber, when the control handle
13
is pressed and after the valve rod
14
and valve cover
15
are pulled upwards, clean water will enter into the casing
121
from the water inlet channels
16
and
17
. Then, the water flow is guided to the nozzle unit
2
through the water draining channel
19
. When water flows to the holes
241
and
242
, the two kinds, of water beams will interact so as to generate spiral water beams C so a;s to have preferred flushing effect. Furthermore, if it is to be closed. It is only necessary to return the handle
13
to original position. By the ejecting force of the compressible spring
141
, the valve rod
14
will resist a downward force. Meanwhile, the valve cover.
15
will close the water draining channel
19
. However, if it is used repeatedly, the valve rod
14
below the valve cover
111
will not close the water draining channel effectively so that water flows into the nozzle unit
2
continuously. Finally, water is drained out from the holes
241
and
242
. Thereby, it can not achieve the object of the present invention.
Especially, when one water inlet channel
17
is used to transfer hot water. The valve cover
15
made of silicon rubber will be hardened so that the valve cover
15
can not close the water draining channel
19
effectively. As a result water flows into the nozzle unit
2
continuously from the water draining channel
19
. Thus, water drains out from the nozzle holes
241
and
242
.
SUMMARY OF THE INVENTION
Accordingly, the primary object of the present invention is to provide a bacteria removing cleaner which comprises a water-stopping control unit and a nozzle means. A plurality of conduits are used for transferring water. The water-stopping control unit has a rotary switch, a main body and a water-stop control valve for controlling the water inlet and water stopping. The main body is spaced into a water outlet space and a water inlet space. A water-stop control valve is installed at the interface of the water inlet space and the water outlet space. The top end of the water-stop control valve is connected to the rotary switch. The water-stop control valve is utilized to control water flow. By rotating a rotary switch, a washing time can be controlled effectively; moreover, the bacteria removing cleaner is capable of being assembled to a stool rapidly and quickly. Thereby, the lifetime is prolonged.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.
