When cleaning manually, a special degreasing cleaner needs to be used for wiping, and a clean wet cloth also needs to be used for wiping again. The procedure is cumbersome. Due to the large wall space, it is time-consuming and laborious to clean the wall, and the efficiency is low. Content of the Utility Model

[0003] The purpose of the utility model is to provide a wall cleaning device to solve the technical problems of time-consuming, laborious and low efficiency in cleaning the kitchen wall in the prior art.

[0005] The utility model discloses a wall cleaning device, which comprises a driving mechanism, a device body, a cleaning mechanism and a drain tank. The driving mechanism is connected to the cleaning mechanism, and the output end of the driving mechanism is connected to the device body to drive the cleaning mechanism to move relative to the device body along a first direction. The cleaning mechanism comprises a steam generating assembly, a brush cleaning assembly and a high-pressure air blowing assembly which are arranged at intervals along the first direction. The drain tank is located below the cleaning mechanism.

[0006] The utility model has at least the following beneficial effects: When the wall needs to be cleaned, the driving mechanism, the steam generating assembly and the brush cleaning assembly are started. At this time, the driving mechanism drives the cleaning mechanism to move along the first direction, so that the steam generating assembly and the brush cleaning assembly move along with the cleaning mechanism, and respectively spray steam on the wall to dissolve the oil stains and wash the wall. After the wall is dissolved and washed by steam, the driving mechanism drives the cleaning mechanism to move in the opposite direction, so that the high-pressure air blowing assembly moves along with the cleaning mechanism and generates high-pressure air to blow on the cleaned wall to mix the small water droplets remaining on the wall into large water droplets, which then flow downward into the drain tank and are collected.

[0007] The cleaning mechanism can automatically clean, and move and clean to other walls through the driving mechanism, reducing manual labor and cleaning time, and improving the cleanliness and cleaning efficiency of the kitchen wall.

[0008] As a further improvement of the above technical solution, the cleaning mechanism comprises a control mechanism, and the control mechanism is electrically connected to the driving mechanism, the steam generating assembly, the brush cleaning assembly and the high-pressure air blowing assembly respectively.

[0009] With the above settings, the driving mechanism, steam generating assembly, brush cleaning assembly, and high-pressure blowing assembly can be automatically opened and closed through the control mechanism setting program, making the use of the wall cleaning device more intelligent and convenient.

[0010] As a further improvement of the above technical solution, a rack is provided on the device body, the rack extends along a first direction, the driving mechanism includes a driving motor and a transmission gear set, the driving motor is connected to the cleaning mechanism, the output end of the driving motor is drivingly connected to the transmission gear set, and the transmission gear set meshes with the rack.

[0011] With the above settings, when the driving motor starts, it drives the transmission gear set to rotate, so that the transmission gear set rotates relative to the rack, thereby realizing the movement of the cleaning mechanism relative to the device body along the first direction.

[0012] As a further improvement of the above technical solution, a first guide member is rotatably connected to the cleaning mechanism, and at least two first guide members are provided and respectively slidably connected to opposite end faces of the rack.

[0013] With the above settings, the cleaning mechanism clamps opposite end faces of the rack through at least two first guide members, so that the movement of the cleaning mechanism is more stable and prevents the cleaning mechanism from shifting during movement.

[0015] With the above settings, the water drain tank is fixed through the connected device body. At least two second guide members are provided at the bottom of the cleaning mechanism, and the two second guide members support the moving member by sliding on the inner groove surfaces of the water drain tank along the second direction, avoiding the cleaning mechanism from shifting in the second direction during movement.

[0016] As a further improvement of the above technical solution, the steam generating assembly includes a steam generator, a water spray port, and a nozzle. The steam generator is connected to the water spray port through a pipeline. A plurality of water spray ports are provided and spaced along the up and down direction. A plurality of nozzles are provided and respectively connected to the plurality of water spray ports in one-to-one correspondence.

[0017] With the above settings, the steam generator generates high-temperature steam and uniformly delivers it to a plurality of water spray ports. The plurality of water spray ports are spaced along the up and down direction to uniformly spray high-temperature steam on the upper and lower walls. The nozzle is used to atomize the high-temperature steam to expand the spraying area of the high-temperature steam and dissolve more oil stains on the wall.

[0018] As a further improvement of the above technical solution, the brush cleaning assembly includes a brush roller and a brush motor that are drivingly connected, and the opposite ends of the brush roller in the extending direction are rotatably connected to the cleaning mechanism.

[0019] With the above arrangement, the opposite ends of the brush roller are rotatably connected to the cleaning mechanism to be stably mounted on the cleaning mechanism. The output end of the brush motor is drivingly connected to the brush roller, driving the brush roller to rotate so that the brush roller can wash the wall surface.

[0020] As a further improvement of the above technical solution, the cleaning mechanism includes an installation cavity and a water-retaining cover. The water-retaining cover divides the installation cavity into a waterproof cavity and a working cavity. The drive motor, the steam generator, and the brush motor are located in the waterproof cavity, and the water spray nozzle and the brush roller are located in the working cavity.

[0021] With the above arrangement, when the steam generating assembly and / or the brush cleaning assembly are working, the separately arranged working cavity and waterproof cavity can prevent the sprayed steam and the water splashed by the rotation of the brush roller from contacting the energized devices such as the drive motor, the steam generator, and the brush motor, avoiding damage to the energized devices due to water ingress.

[0041] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the attached drawings. The role of the attached drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it should not be construed as a limitation on the protection scope of the present utility model.

[0042] In the description of the present utility model, it should be understood that when it comes to orientation descriptions, such as the orientations or positional relationships indicated by up, down, front, back, left, right, etc., they are based on the orientations or positional relationships shown in the drawings. This is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0043] In the description of the present utility model, if there are vocabulary descriptions such as "a number of", its meaning is one or more, and the meaning of multiple is two or more. Understandings such as greater than, less than, exceeding, etc. do not include the base number, and understandings such as above, below, within, etc. include the base number. If there is a description of first, second, third, etc., it is only for the purpose of distinguishing technical features and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or the sequence relationship of the indicated technical features.

[0044] It should be noted that in the drawings, the X direction is from the front side to the back side of the wall cleaning device; the Y direction is from the right side to the left side of the wall cleaning device; the Z direction is from the lower side to the upper side of the wall cleaning device.

[0045] In the description of the present utility model, unless otherwise clearly defined, words such as setting, installing, connecting, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.

[0046] Refer to Figures 1 to 4 , and several embodiments of the wall cleaning device of the present utility model are given below.

[0047] As Figures 1 to 4 shown, the wall cleaning device of the embodiment of the present utility model includes a device body 100, a driving mechanism, a cleaning mechanism 300, and a water drain tank 700.

[0048] It can be understood that the driving mechanism is connected to the cleaning mechanism 300, and the output end of the driving mechanism is connected to the device body 100. When the driving mechanism is started, the cleaning mechanism 300 moves relative to the device body 100 in the first direction.

[0049] It is understandable that the cleaning mechanism 300 includes a steam generating assembly, a brush cleaning assembly and a high-pressure blowing assembly arranged at intervals along the first direction. Among them, the steam generating assembly is used to produce and spray high-temperature steam to the wall surface, and the high-temperature steam can melt the oil stains on the wall surface, making it easier to clean stubborn oil stains. The brush cleaning assembly can effectively brush away oil stains, dust and other impurities on the wall surface, thereby improving the cleaning effect on the wall surface. The high-pressure blowing assembly is used to generate high-pressure air and blow it toward the wall surface, so as to mix the small water droplets remaining on the wall surface into large water droplets and flow into the drain tank 700, so as to achieve the effect of drying the wet wall surface and avoid the growth of bacteria.

[0050] It is understandable that the drain tank 700 is located below the cleaning mechanism 300. Figure 1 As shown, the sewage generated when the cleaning mechanism 300 cleans the wall surface is received to prevent the sewage from flowing to the kitchen countertop or floor due to gravity.

[0051] With such arrangement, the cleaning mechanism 300 can effectively clean and dry the wall surface, thereby improving the cleaning effect and efficiency of the wall surface. The driving mechanism drives the cleaning mechanism 300 to move along the first direction, so that the cleaning mechanism 300 automatically cleans different positions of the wall surface, without the need to manually move the position of the cleaning mechanism 300, making the use of the wall cleaning device more convenient, time-saving and labor-saving.

[0052] In some embodiments, the first direction may be an up-down direction, that is, the cleaning mechanism 300 cleans the wall surface from an up-down direction.

[0053] In this embodiment, the first direction is a horizontal left-right direction, that is, the cleaning mechanism 300 cleans the wall surface from the left-right direction.

[0054] It can be understood that the cleaning mechanism 300 includes a control mechanism 800, which is electrically connected to the driving mechanism, the steam generating component, the brush cleaning component and the high-pressure blowing component respectively, and the control mechanism 800 can open or close one or more electrically connected mechanisms or components.

[0055] With such a configuration, when the wall cleaning device is started, the control mechanism 800 starts the steam generating assembly 5 seconds in advance to ensure that the steam generating assembly sprays high-temperature steam onto the wall, and then the control mechanism 800 starts the brush cleaning assembly and the driving mechanism, so that the brush cleaning assembly starts to scrub the wall, and the driving mechanism drives the cleaning mechanism 300 to move left and right to spray steam and scrub the left and right walls. When the cleaning is completed, the control mechanism 800 turns off the steam generating assembly and the brush cleaning assembly, and turns on the high-pressure blowing assembly, which dries the wet wall after cleaning, and the driving mechanism drives the cleaning mechanism 300 to move left and right to dry the left and right walls. When the drying is completed, the control mechanism 800 turns off the driving mechanism and the high-pressure blowing assembly, and at this time, the wall is cleaned.

[0056] It is understandable that the cleaning mechanism 300 is disposed at the leftmost end or the rightmost end of the device body 100 .

[0057] In this embodiment, the cleaning mechanism 300 is disposed at the rightmost end of the device body 100. Figure 1 As shown, at this time, the steam generating assembly is located to the left of the brush cleaning assembly, ensuring that when the driving mechanism is started, the driving mechanism drives the cleaning mechanism 300 to move to the left, and the wall is first sprayed with high-temperature steam and then scrubbed by the brush cleaning assembly. When the cleaning mechanism 300 is driven to the leftmost end of the device body 100, the cleaning mechanism 300 just completes the cleaning of the wall corresponding to the device body 100. At this time, the driving mechanism starts the high-pressure blowing assembly and drives the cleaning mechanism 300 to move to the right, so that the high-pressure blowing assembly blows the wall dry from left to right. When the cleaning mechanism 300 is driven back to the rightmost end of the device body 100, the cleaning mechanism 300 just completes the drying of the cleaned wall. At this time, the position of the cleaning mechanism 300 is just enough to allow the wall cleaning device to clean the wall for the next time.

[0058] It is understandable that the high-pressure blowing assembly is located next to the brush cleaning assembly so that when the high-pressure blowing assembly is in a blowing state, the remaining wind can blow toward the brush cleaning assembly, thereby improving the drying efficiency of the brush cleaning assembly and preventing bacteria from growing on the brush cleaning assembly.

[0059] In this embodiment, the brush cleaning assembly is located between the steam generating assembly and the high-pressure blowing assembly. The brush cleaning assembly separates the steam generating assembly and the high-pressure blowing assembly to prevent the steam-delivering pipe of the steam generating assembly and the air-delivering pipe of the high-pressure blowing assembly from interfering with each other.

[0060] In some embodiments, the driving mechanism may be an electric cylinder, a linear module, a lead screw motor, etc.

[0061] In this embodiment, the cleaning mechanism 300 is moved left and right by the meshing rack 110 and the transmission gear set 220. At this time, the cleaning mechanism 300 is not prone to forward and backward displacement, thereby limiting the cleaning mechanism 300 to be close to the wall, thereby ensuring that the steam generated by the steam generating component is effectively sprayed onto the wall, and the brush cleaning component can effectively brush away impurities on the wall, thereby improving the cleaning effect of the cleaning mechanism 300.

[0062] It can be understood that the device body 100 is provided with a rack 110, and the rack 110 extends along a first direction of left and right. Figure 1 Correspondingly, the driving mechanism includes a driving motor 210 and a driving gear set 220 that are connected in a transmission manner. The driving motor 210 is connected to the cleaning mechanism 300, as shown in FIG. Figure 3As shown, the transmission gear set 220 meshes with the rack 110. When the drive motor 210 is started, the output shaft of the drive motor 210 drives the transmission gear set 220 to rotate, so that the transmission gear set 220 rotates and meshes with the rack 110, realizing the left - right movement of the cleaning mechanism 300.

[0063] It can be understood that the transmission gear set 220 includes at least one drive gear to realize the transmission connection between the drive motor 210 and the rack 110. In this embodiment, the transmission gear set 220 includes two meshing drive gears. One of the drive gears is connected to the output shaft of the drive motor 210, and the other drive gear meshes with the rack 110, as Figure 2 shown, so that the drive motor 210 has a better installation position on the cleaning mechanism 300, and the moving speed of the cleaning mechanism 300 can be adjusted by two drive gears with different diameters.

[0064] In this embodiment, the drive motor 210 is a worm - gear reduction motor.

[0065] It can be understood that the electrical connection between the drive mechanism and the control mechanism 800 is actually the electrical connection between the drive motor 210 and the control mechanism 800.

[0066] It can be understood that the cleaning mechanism 300 includes a front cover 360 and a rear cover 370. The front cover 360 and the rear cover 370 are covered and connected to form an installation cavity 380 for accommodating a steam - generating component, a brush - cleaning component, and a high - pressure blowing component, as Figure 2 shown.

[0067] It can be understood that the cleaning mechanism 300 includes a first guide member 310. The first guide member 310 is rotatably connected to the front cover 360, as Figure 2 shown. There are at least two first guide members 310. At least two first guide members 310 sandwich the rack 110 from opposite ends respectively. The rack 110 is slidably connected to at least two first guide members 310, providing a stable supporting effect for the cleaning mechanism 300. When the drive mechanism is started, at least two first guide members 310 slide left and right along the opposite ends of the rack 110 respectively to guide the left - right movement of the cleaning mechanism 300.

[0068] In some embodiments, at least two first guide members 310 slide on the front end face and the rear end face of the rack 110 respectively to prevent the cleaning mechanism 300 from shifting forward and backward.

[0069] In this embodiment, at least two first guide members 310 slide on the upper end face and the lower end face of the rack 110 respectively to clamp and fix the rack 110 from the up - down direction, prevent the cleaning mechanism 300 from shifting up and down, and can reduce the thickness of the cleaning mechanism 300 in the front - back direction, thereby reducing the front - back volume of the wall - cleaning device.

[0070] It is understandable that there are four first guiding members 310, two of which slide on the upper end surface of the rack 110, and the other two first guiding members 310 slide on the lower end surface of the rack 110, as Figure 2 shown.

[0071] In some embodiments, the rack 110 can be in the shape of a cube, and the first guiding member 310 is a pulley. Two first guiding members 310 slide along the upper end surface and the lower end surface of the rack 110 respectively, and the meshing position of the rack 110 and the transmission gear set 220 can be arranged on the upper end surface or the lower end surface of the rack 110.

[0072] In this embodiment, the rack 110 is cylindrical, and the first guiding member 310 is a U-groove bearing. The upper end of the rack 110 is clamped in the U-groove bearing located above, and the lower end of the rack 110 is clamped in the U-groove bearing located below, avoiding the deviation of the first guiding member 310 from the rack 110 in the front-back direction or the up-down direction, making the left-right movement of the cleaning mechanism 300 more stable. Moreover, the contact area between the U-groove bearing and the cylindrical rack 110 is larger, avoiding the situation that when the U-groove bearing slides relative to the rack 110, the wall surface of the U-groove bearing is clamped in the teeth of the rack 110, and there are multiple jams during the movement of the cleaning mechanism 300.

[0073] In some embodiments, the water drain tank 700 is connected to the bottom of the cleaning mechanism 300. The water drain tank 700 obtains a supporting effect through the cleaning mechanism 300 and moves left and right with the cleaning mechanism 300 to accurately collect the sewage generated by the cleaning mechanism 300 and reduce the length of the water drain tank 700. However, it is easy to occur that the water drain tank 700 moves with the cleaning mechanism 300 before the sewage completely flows into the water drain tank 700, resulting in the sewage still flowing onto the kitchen countertop or the ground.

[0074] In this embodiment, the device body 100 is connected to the water drain tank 700, and the position of the drain basket is fixed through the device body 100 and a supporting effect is provided for the drain basket. The water drain tank 700 extends in the left-right direction and is greater than or equal to the moving length of the cleaning mechanism 300, so that the water drain tank 700 can completely receive the sewage left on the wall after the cleaning mechanism 300 finishes cleaning.

[0075] Furthermore, the cleaning mechanism 300 includes a second guiding member 320, and the second guiding member 320 is rotatably connected to the bottom of the front cover 360. The second guiding member 320 is located in the water drain tank 700, as Figures 1 to 3 shown.

[0076] It can be understood that there are at least two second guiding members 320. At least one second guiding member 320 is in contact with and slidably connected to one inner groove surface of the drain tank 700 along the second direction, and at least one second guiding member 320 is in contact with and slidably connected to the other inner groove surface of the drain tank 700 along the second direction. The second guiding member 320 guides the left - right movement of the cleaning mechanism 300 through the inner groove surface of the drain tank 700, further preventing the cleaning mechanism 300 from shifting during movement.

[0077] It can be understood that the second direction is a horizontal direction perpendicular to the first direction, that is, the second direction is the front - rear direction. The second guiding member 320 can prevent the cleaning mechanism 300 from shifting forward and backward during movement.

[0078] In this embodiment, the second guiding member 320 is a pulley.

[0079] It can be understood that the steam - generating assembly includes a steam generator 410, a water - spraying port 421, and a nozzle 430. Specifically, the steam generator 410 is hidden and disposed in the installation cavity 380. The steam generator 410 is connected to a water - spraying pipe 420 through a pipeline in the installation cavity 380, as Figure 3 shown. The front cover 360 is provided with an opening facing forward, and the opening is in communication with the installation cavity 380. The water - spraying pipe 420 is fixed in the installation cavity 380, and a plurality of water - spraying ports 421 are provided on the side thereof facing the opening, as Figure 2 shown, to uniformly supply high - temperature steam to each water - spraying port 421. The water - spraying pipe 420 extends in the up - down direction, and a plurality of water - spraying ports 421 are spaced apart in the up - down direction to uniformly supply high - temperature steam to the wall surface during the left - right movement process. The water - spraying ports 421 are disposed at the front end of the water - spraying pipe 420, and a nozzle 430 is connected to each water - spraying port 421, as Figure 2 shown, to atomize the high - temperature steam, expand the spraying area, and dissolve more oil stains.

[0080] It can be understood that the nozzle 430 can be a copper nozzle or a stainless - steel nozzle, etc. In this embodiment, the nozzle 430 is a copper nozzle with good heat - conducting performance.

[0081] It can be understood that the electrical connection between the steam - generating assembly and the control mechanism 800 is actually the electrical connection between the control mechanism 800 and the steam generator 410, the water pump 340, and the water valve 350 respectively.

[0082] It can be understood that the wall - cleaning device further includes a pressure - reducing valve 920, as Figure 1 shown. The input end of the pressure - reducing valve 920 is installed on the household water pipe to control the incoming water pressure. The steam - generating assembly further includes a water valve 350 and a water pump 340, as Figure 2 and Figure 3As shown, the output end of the pressure reducing valve 920 is connected to the water valve 350 through a pipeline. The input end and the output end of the water pump 340 are respectively connected to the water valve 350 and the steam generator 410 to convey liquid into the steam generator 410.

[0083] It can be understood that the brush cleaning assembly includes a brush roller 520 and a brush motor 510, as Figure 2 and Figure 3 shown. Specifically, the output end of the brush motor 510 is drivingly connected to the brush roller 520 to drive the brush roller 520 to rotate. The brush motor 510 is a planetary reduction motor to reduce the rotational speed of the brush roller 520 during operation, increase the output torque, and provide sufficient driving force for the brush roller 520. The output end of the brush motor 510 is drivingly connected to the brush roller 520 through a synchronous belt 530, as Figure 2 and Figure 3 shown, so that the brush roller 520 and the brush motor 510 can be arranged in the first direction, reducing the up and down length of the cleaning mechanism 300. The brush roller 520 extends in the up and down direction to increase the wall washing area. The upper end and the lower end of the brush roller 520 are rotatably connected to the front cover 360 to obtain a supporting effect through the front cover 360.

[0084] In this embodiment, the brush roller 520 corresponds to the opening before and after, and the brush part on the brush roller 520 extends out of the opening. Since the upper end of the cleaning mechanism 300 is guided by the first guiding member 310 and the lower end of the cleaning mechanism 300 is guided by the second guiding member 320, when cleaning the wall, the brush can be closely attached to the wall, ensuring that the rotating brush roller 520 produces a cleaning effect on the wall.

[0085] It can be understood that the electrical connection between the brush cleaning assembly and the control mechanism 800 is actually the electrical connection between the brush motor 510 and the control mechanism 800.

[0086] It can be understood that the high-pressure blowing assembly includes a brushless blower 610 and an air duct 620. The brushless blower 610 is connected to the air duct 620 through a pipeline. The air duct 620 corresponds to the opening before and after, and a plurality of air outlets 630 are provided at one end facing the opening. The plurality of air outlets 630 are arranged at intervals in the up and down direction, as Figure 2 shown.

[0087] It can be understood that the electrical connection between the high-pressure blowing assembly and the control mechanism 800 is actually the electrical connection between the brushless blower 610 and the control mechanism 800.

[0088] In this embodiment, the cleaning mechanism 300 includes a water isolation cover 390. The water isolation cover 390 is located in the installation cavity 380 to divide the installation cavity 380 into a working cavity 382 and a waterproof cavity 381, so that the working cavity 382 and the waterproof cavity 381 are independent of each other, as Figure 3As shown. Specifically, the water-proof cover 390 is connected to the front cover 360 to form a waterproof cavity 381. The front cover 360, the rear cover 370, and the water-proof cover 390 form a working cavity 382, and the opening is in communication with the working cavity 382 in the front and back directions.

[0089] It can be understood that the energized devices such as the drive motor 210, the steam generator 410, the brush motor 510, and the brushless blower 610 are installed in the waterproof cavity 381, and the water spray nozzles 421 and the brush rollers 520 are installed in the working cavity 382. As Figure 3 shown, so that the steam sprayed by the water spray nozzles 421 through the nozzles 430 and the water splashes splashed by the rotation of the brush rollers 520 are blocked by the water-proof cover 390, so that the energized devices such as the drive motor 210 are always kept dry, avoiding faults such as short circuit due to water ingress, electric shock, and circuit damage of the energized devices.

[0090] It can be understood that a warning light 330 is provided on the outer wall surface of the cleaning mechanism 300. As Figure 1 and Figure 3 shown, the warning light 330 is electrically connected to the control mechanism 800. When the steam generating assembly is in the working state, the control mechanism 800 energizes and starts the warning light 330 to remind people not to approach and avoid accidents of being scalded by high-temperature steam.

[0091] In this embodiment, since the water spray nozzles 421 face forward towards the wall surface, therefore, the warning light 330 is located on the rear wall surface of the cleaning mechanism 300, that is, the warning light 330 is provided on the rear cover 370. As Figure 1 and Figure 3 shown.

[0092] It can be understood that a drain trough 710 is provided in the middle of the drain tank 700. As Figure 1 shown, the inner bottom wall of the drain tank 700 is inclined downward towards the direction close to the drain trough 710, so that the sewage flowing into the left end and the right end of the drain tank 700 flows along the inclined inner bottom wall into the drain trough 710 to be collected. The inner bottom wall of the drain trough 710 is communicated with a drain pipe 720. As Figure 1 and Figure 4 shown, the sewage flows out of the wall cleaning device along the drain pipe 720.

[0093] Furthermore, a filter screen frame 730 is clamped in the drain trough 710 to filter solid impurities and avoid blocking the drain pipe 720. As Figure 4 shown.

[0094] In addition, a collecting member 740 is also clamped in the drain trough 710. The collecting member 740 is provided with a collecting groove 741. As Figure 4 shown. When the drain pipe 720 is difficult to connect to the sewage network, the sewage can be collected in the collecting groove 741. The collecting member 740 is connected with a handle 742, and people can directly take out the collecting member 740 through the handle 742 and pour out the sewage.

[0095] It can be understood that the collecting member 740 can be snap-fitted onto the filter screen holder 730.

[0096] Furthermore, a guiding plate 750 extends upwardly and obliquely on one side of the water draining tank 700 close to the wall surface to guide sewage to flow into the water draining tank 700, as Figure 1 and Figure 4 shown.

[0097] It can be understood that the control mechanism 800 includes a circuit board (PCB). The circuit board is located in the installation cavity 380. The power supply is output from an external electrical box and transmitted to the circuit board through the nylon cable carrier 910, as Figure 1 shown.

[0098] It can be understood that the pipeline connecting the pressure reducing valve 920 to the water valve 350 can also be laid in the nylon cable carrier 910, as Figure 1 shown.

[0099] The preferred embodiments of the present utility model have been specifically described above, but the creation of the present utility model is not limited to the described embodiments. Those skilled in the art can also make various equivalent variations or substitutions without departing from the spirit of the present utility model. These equivalent variations or substitutions are all included within the scope defined by the claims of this application.
