Description

[0001] This application is a divisional application of Chinese patent application No. 202211255574.4, and the invention name is “An integrated water tank capable of automatic pressure regulation and automatic circulation filtration”, the contents of which are incorporated herein by reference. Technical Field

[0002] The present invention relates to the technical field of cleaning appliances, and in particular to an integrated water tank capable of automatic pressure regulation and automatic circulation filtration. Background Art

[0003] In daily life, we are accustomed to using cleaners to clean our homes, daily necessities, and travel items. To ensure water consumption, cleaners are often equipped with water tanks. Currently, some cleaners use separate cleaning and wastewater tanks, while others use integrated recycling tanks. Integrated cleaning and wastewater tanks primarily process wastewater from cleaning products before entering the tank, thereby increasing water recycling.

[0004] In addition, because water tanks are generally sealed containers, in order to ensure the normal flow of clean and dirty water during operation, the water tank needs to be depressurized. At the same time, integrated water tanks for cleaning and sewage usually need to be equipped with a filter device. Currently, water tanks with filter devices on the market generally have the filter device installed at the sewage inlet, filtering the sewage as it enters. The filtered water is then used to clean the items or environment that need to be cleaned through the water outlet. The disadvantage of this design is that too many impurities will remain in the filter device, which will easily clog the filter holes over time, thereby affecting the filtering effect. In addition, the filter device is generally installed in the water tank, which is particularly inconvenient to clean. Summary of the Invention

[0005] The main technical problem solved by the present invention is to provide an integrated water tank that can automatically adjust pressure and automatically circulate and filter. The water tank can filter the sewage flowing back into the water tank while also releasing the pressure accumulated in the entire water tank, thereby reducing the adverse effect of increased pressure in the cleaner pipeline when the pressure in the water tank increases.

The pressure relief channel is provided with two pre-pressure relief ports respectively connected to the cavity and a pre-pressure relief port control component respectively controlling one of the two pre-pressure relief ports to connect to the pressure relief port through the pressure relief channel.

[0027] Furthermore, the pressure balancing mechanism is connected to the filter assembly, and when the pressure relief port of the pressure balancing mechanism is connected to the exhaust port of the filter assembly, a part of the pressure relief channel is formed.

[0040] More specifically, the filtering components include:

[0041] A long box-shaped frame, with an open top and hollowed-out sides and bottom, and guide wings arranged on both sides of the long box-shaped frame;

[0046] Furthermore, the outer annular wall of the abutment, the surrounding wall of the sewage channel, the central solid part of the bayonet part and the inner wall corresponding to the sewage channel together enclose a sewage side entry channel. The entrance of the sewage channel is the sewage outlet of the water tank bayonet assembly exposed when the abutment is compressed by external force. The outlet of the sewage channel is the sewage pipe interface. The part of the sewage channel between the sewage outlet and the sewage pipe interface is the sewage side entry channel.

[0047] Furthermore, a sewage pipe is connected at the sewage pipe interface, and the sewage pipe extends to the center of the water tank so that the sewage sent back to the water tank can fully contact the pressure relief filter assembly and then be filtered into clean water and sent out of the water tank again; the sewage outlet, sewage side inlet channel, sewage pipe interface and sewage pipe together form the entire sewage channel.

[0048] Furthermore, when the abutment of the elastic abutment assembly of the sewage channel on the bayonet portion is pressed by an external force, the abutment further compresses the spring, thereby opening the sewage channel. The inner side wall end surface of the bayonet portion is higher than the chamfered surface and side surface of the abutment, and the sewage can enter the sewage side inlet channel through the sewage outlet, the inner side wall end surface of the bayonet portion and the gap between the abutment, and further enter the water tank cavity and then participate in the filtration cycle.

[0049] Furthermore, the clean water channel and the exhaust channel are equipped with:

The pressure relief filter assembly is provided with a bayonet part bottom wall abutting one end of the clean water interface and the exhaust interface. Two openings are provided on the bottom wall of the bayonet part, respectively corresponding to the clean water interface and the exhaust interface. When the piston valve components at both ends of the two-way piston valve assembly of the clean water channel and / or the exhaust channel are pressed by external force or pressure shock, the passage of the corresponding clean water channel and / or the exhaust channel is opened.

[0053] Compared with the prior art, the technical effects and advantages of the present invention are:

The water tank can filter the sewage flowing back into the water tank while also releasing the pressure accumulated in the entire water tank. When in use, the water tank is in motion and basically will not be in a horizontal state for a long time. When the two pressure relief control switches are not in the same horizontal line, one of the pressure relief control switches is in the closed state, which will inevitably cause a pre-pressure relief port to be connected to the pressure relief channel, so that the pressure in the cavity can be released, thereby balancing the pressure inside and outside the water tank, and effectively reducing the negative impact of the pressure imbalance in the water tank. Even when the circulating cleaning container is in a horizontal state, the two pressure relief control switches are in the same horizontal line. One of the pressure relief control switches can be flushed open by the liquid in the cavity under the action of inertia, which will inevitably cause a pre-pressure relief port to be connected to the pressure relief channel, so that the pressure in the cavity can be released, thereby balancing the pressure inside and outside the water tank.

[0092] The solution of this application will be described in detail below with reference to the accompanying drawings.

[0093] Figures 1-10 As shown, the present invention provides an embodiment of an integrated water tank capable of automatic pressure regulation and automatic circulation filtration.

[0094] Specifically, if Figure 1 、 Figure 2、 Figure 3 As shown, the integrated water tank for the cleaner includes a cylindrical water tank body component 2 with an open large end and a closed small end and a cavity, a water tank bayonet component 1 installed on the end face of the small end of the water tank body component 2, a pressure relief filter component 3 slidably engaged in the water tank body component 2, and a water tank cover component 4 covering the large end opening of the water tank body component 2 (not marked in the figure), wherein the water tank body component 2 includes a bayonet portion 21 arranged on the end face of the small end of the water tank body component 2 (not marked in the figure) for allowing liquid to enter and exit the cavity, the bayonet portion 21 is provided with a clean water channel 211, a sewage channel 212 and an exhaust channel 213, and the pressure accumulated in the cavity can be discharged through the pressure relief filter component 3 along the The exhaust channel 213 provided on the bayonet portion 21 is discharged out of the water tank. The water tank bayonet assembly 1 is further detachably fastened to the bayonet portion 21 by screws. The water tank bayonet assembly 1 can further prevent the liquid contained in the cavity from leaking to other parts of the vehicle cleaner during operation. The parts of the water tank bayonet assembly 1 are also conveniently removed from the cleaner body (not shown in the figure) when the liquid in the cavity needs to be replaced. After removal, the entire water tank can still allow the clean water channel 211, the sewage channel 212 and the exhaust channel 213 in the bayonet portion 21 to automatically close, so that the entire water tank can still be leak-proof when the liquid in the cavity is replaced.

[0095] Specifically, if Figure 2 、 Figure 4 As shown, the water tank body assembly 2 includes a water tank body 20 with a cylindrical shape, a large end open and a small end closed and with a cavity, and a bayonet portion 21 that closes the cavity at the small end of the water tank body 20. The water tank body 20 and the bayonet portion 21 are integrally formed. The side wall (not marked in the figure) of the water tank body 20 has a single structure relative to the end wall (not marked in the figure) of the bayonet portion 21, but the formed wall thickness is consistent. The bayonet portion 21 is provided with a multi-layer wall thickness structure (not marked in the figure) in the depth direction of the cylindrical water tank body 20. Specifically, as Figure 2 、 Figure 4 As shown, the multi-layered wall structure of the bayonet portion 21 includes a first stepped end surface 217 that abuts the end surface of the pressure relief filter assembly 3 pointing toward the water tank bayonet assembly 1, and a second stepped end surface 216 that is parallel to the first stepped end surface 217 and encloses a sewage channel wall 2123. This design not only ensures the rigidity of the entire water tank body, but also enhances the bayonet portion 21's ability to withstand external impacts. It also ensures that the open end (not shown) of the water tank body 20 can easily open and close the water tank cover assembly 4.

[0096] As a further improved embodiment, the multi-layer wall thickness structure of the bayonet portion 21 further includes a third step end surface 215 that abuts against one end surface of the bayonet sealing plate 11 of the water tank bayonet assembly 1, and a fourth step end surface 210 that abuts against one end surface of the bayonet plate 10 of the water tank bayonet assembly 1. This design can improve the ability of the bayonet portion 21 to resist external impact while ensuring the rigidity of the entire water tank body, and can also ensure that the open end of the water tank body 20 (not shown in the figure) can easily open / close the water tank cover assembly 4.

[0097] like Figure 3 、 Figure 4 As shown, the bottom of the cylindrical body (not marked in the figure) where the water tank body 20 and the cleaner body (not marked in the figure) meet is in a straight state, and two abutment surfaces 201 are provided along the waist portion (not marked in the figure) that is inclined upward along the straight bottom. The abutment surfaces 201 of the water tank body 20 and the straight bottom and the inclined waist portion connecting the two are in contact with the cleaner body. Figure 4 As shown, the inner side wall of the water tank body 20 is provided with two clamping ribs 202 parallel to the axis of the water tank body 20 for slidingly clamping the pressure relief filter assembly 3. One end of the clamping rib 202 extends along the depth direction of the water tank body 20 to the large end opening of the water tank body 20, and the other end of the clamping rib 202 extends along the depth direction of the water tank body 20 to the middle of the water tank body 20.

[0098] like Figure 2 As shown, combined Figure 1 、 Figure 3 、 Figure 4 、 Figure 5Taken together, the end face of the sewage channel 212 of the bayonet portion 21 is provided with an abutment 131, and the abutment 131 is provided with a chamfer at one end facing the outside of the water tank body 20, and a double-layer connecting ring wall (not marked in the figure) that is not conductive to the outside. The hollow part of the double-layer connecting ring wall is just clamped with a spring 132. The end face of the sewage channel 212 of the bayonet portion 21 is also provided with a sewage channel surrounding wall 2123 that is closed and abutted with the outer ring wall of the abutment 131. The sewage channel surrounding wall 2123 is provided with a ring wall corresponding to the inner ring wall of the abutment 131 on the part of the third step surface (not marked in the figure). The other end of the spring 132 is clamped on the ring wall, and the abutment 131 clamps and connects a spring 132 to form a complete elastic abutment assembly 13. The outer annular wall of the abutment 131 (not marked in the figure), the sewage channel surrounding wall 2123, the central solid part 218 of the bayonet part 21, and the inner wall corresponding to the sewage channel 212 (not marked in the figure) together enclose a sewage side inlet channel 2121. The entrance of the sewage channel 212 is the sewage outlet 102 of the water tank bayonet assembly 1 that is exposed when the abutment 131 is compressed by external force. The outlet of the sewage channel 212 is the sewage pipe interface 2122. The part of the sewage channel 212 between the sewage outlet 102 and the sewage pipe interface 2122 is called the sewage side inlet channel 2121. In order to allow the sewage sent back through the return pipe (not shown in the figure) to reach a more central position of the water tank, a sewage pipe (not shown in the figure) can be plugged into the sewage pipe interface 2122, so that the sewage sent back to the water tank can be more fully in contact with the pressure relief filter assembly 3 and filtered into clean water before being sent out of the water tank again. The sewage inlet 102, the sewage side inlet channel 2121, the sewage pipe interface 2122 and the sewage pipe (not shown in the figure) together form the entire sewage channel 212. The elastic abutment assembly 13 includes an abutment 131 and a spring 132. When the abutment 131 is pressed by an external force, the abutment 131 compresses the spring 132, thereby opening the sewage channel 212. Figure 11 As shown, when the abutment 131 of the elastic abutment assembly 13 of the sewage channel 212 of the bayonet portion 21 is pressed by an external force, the abutment 131 further compresses the spring 132, and the inner side wall end surface of the bayonet portion 21 is higher than the chamfered surface and side surface of the abutment 131. Sewage can enter the sewage side inlet channel 2121 through the sewage outlet 102, the inner side wall end surface of the bayonet portion 21 and the gap between the abutment 131, and further enter the water tank cavity and then participate in the filtration cycle.

[0099] like Figure 5As shown, the water tank bayonet assembly 1 includes a bayonet end plate 10 that can abut the corresponding interface of the cleaner body (not marked in the figure) and a bayonet sealing gasket 11 that is clamped between the bayonet end plate 10 and the bayonet part 21 and acts as an elastic seal. The bayonet end plate 10 is provided with a clean water port 101, a sewage port 102 and an exhaust port 103. The bayonet sealing gasket 11 is provided with a clean water port 111, a sewage port 112 and an exhaust port 113. The bayonet end plate 10 is also provided with an inner concave step surface (not marked in the figure) that is consistent with the outer edge contour of the bayonet sealing gasket 11. A clean water port eaves (not marked in the figure) is extended upward from the step surface along the inner wall of the clean water port 101, and the outer wall of the clean water port eaves can be just snapped into the clean water port The inner wall of the outlet 111; a sewage outlet eaves (not marked in the figure) is extended upward from the step surface along the inner wall of the sewage outlet 102, and the outer wall of the sewage outlet eaves can be snapped onto the inner wall of the sewage outlet 112; an exhaust outlet eaves (not marked in the figure) is extended upward from the step surface along the inner wall of the exhaust outlet 103, and the outer wall of the exhaust outlet eaves can be snapped onto the inner wall of the exhaust outlet 113; one end face of the bayonet sealing gasket 11 is embedded in the concave step surface of the bayonet end plate 10, and the other end is elastically abutted against the outer end face of the bayonet portion 21 of the water tank body 20. The bayonet end plate 10 clamping the bayonet sealing gasket 11 can be detachably elastically sealed and installed on the bayonet portion 21 of the water tank body 20 by several fastening screws.

[0100] like Figure 2 As shown, combined Figure 5 Taken together, the bayonet end plate 10 installed in the bayonet portion 21 is abutted by the chamfered surface of one end of the piston valve member 121 facing the outside of the water tank body 20 at the first step surface 210. The other end of the piston valve member 121 is provided with a double-layer connecting ring wall (not marked in the figure) that is not conductive to the outside. The hollow part of the double-layer connecting ring wall just clamps a spring 122. The outer ring wall of the double-layer connecting ring wall of the piston valve member 121 is provided with a plurality of mutually clamping teeth (not marked in the figure) that are mutually connected. The other end of the spring 122 just clamps on the other piston valve member that is opposite and clamped to the previous piston valve member with the clamping teeth. The two relatively clamped piston valve members 121 clamp a spring 122 to form a complete two-way piston valve assembly 12. Figure 3 、 Figure 4 As shown, continue to combine Figure 2Together, the clean water channel 211 and the exhaust channel 213 of the bayonet portion 21 are both provided with a two-way piston valve assembly 12. The chamfered surface of one set of piston valve members 121 abuts the bayonet end plate 10 of the bayonet portion 21 at the first step surface 210, while the chamfered surface of the other set of piston valve members 121 abuts the bayonet portion bottom wall 219 at the fourth step surface 217. The pressure relief filter assembly 3 is provided with a clean water port 301 and an exhaust port 302, one end of which abuts the bayonet portion bottom wall 219. The bayonet portion bottom wall 219 is provided with two openings (not shown) corresponding to the clean water port 301 and the exhaust port 302, respectively. When the piston valve members 121 at both ends of the two-way piston valve assembly 12 of the clean water channel 211 and / or the exhaust channel 213 are pressed by external force or pressure shock, the corresponding clean water channel 211 and / or exhaust channel 213 is opened.

[0101] like Figure 7 、 Figure 8 As shown, combined Figure 1 、 Figure 2 、 Figure 4 、 Figure 6 Taken together, the pressure relief filter assembly 3 is slidably engaged in the water tank body assembly 2, which includes a filter assembly 30 with one end abutting against the bottom wall 219 of the bayonet portion of the water tank body assembly 2 and the other end leaving a gap with the water tank cover assembly 4, and a pressure relief assembly 31 with the function of adjusting the pressure in the water tank arranged in the filter assembly 30. The skeleton of the filter assembly 30 (not marked in the figure) is detachably connected to the pressure relief assembly 31. The skeleton of the filter assembly 30 is a long box-shaped skeleton, and the front and rear end walls of the long box-shaped skeleton are solid walls. A clean water interface 301 and an exhaust interface 302 are provided on the front end wall abutting against the bottom wall 219 of the bayonet portion of the water tank body assembly 2, and a handle (not marked in the figure) is provided on the lower part of the rear end wall opposite to the front end wall for facilitating the sliding and removal of the entire pressure relief filter assembly 3 from the water tank body assembly 2. The top of the long box-shaped frame is open, and a circle of slots (not shown) are provided on the top of the long box-shaped frame to which a sealing ring 35 can be elastically clamped. The pressure relief filter assembly 3 is detachably sealed with the top wall of the water tank body assembly 2 through the sealing ring 35. In addition to the two end walls, the other two side walls and the bottom wall of the long box-shaped frame are provided with a large number of hollow areas (not shown in the figure). Figure 8As shown, the outer walls of the two side walls and bottom wall of the long box-shaped frame are equipped with filter screens 304 to cover the hollowed-out areas. Sewage entering the water tank cavity through the sewage channel 212 is filtered by the filter screen 304 and enters the pressure relief filter assembly 3, becoming "sub-clean water". It is then discharged from the water tank cavity through the clean water interface 301 of the pressure relief filter assembly 3 and the clean water channel 211. A guide wing 303 is provided on each side wall of the filter assembly 30 frame. The guide wing 303 slidably abuts against the engaging rib 202 of the water tank body assembly 2. One end of the guide wing 303 extends along the depth direction of the filter assembly 30 frame to the rear end surface of the filter assembly 30 frame where the clean water interface 301 and the exhaust interface 302 are not provided. The other end of the guide wing 303 extends along the depth direction of the filter assembly 30 frame to the middle of the depth direction of the frame.

[0102] like Figure 6 、 Figure 7 、 Figure 8As shown, the pressure relief component 31 and the skeleton of the filter component 30 are integrally formed. Different names are given here only to better reflect the functions of each part. Any deformation and adjustment of the technical solutions described in the previous and next texts are within the scope of protection of this application. The pressure relief component 31 is an "I"-shaped structure connecting the front end face (not marked in the figure) of the skeleton provided with a clean water interface 301 and an exhaust interface 302 and the rear end face (not marked in the figure) not provided with the clean water interface 301 and the exhaust interface 302. The "I"-shaped structure is provided with a pressure relief groove (not marked in the figure) for accommodating a pressure regulating device facing the upper surface of the water tank body component 2. The root of the pressure relief groove connecting the front end face and the rear end face of the "I"-shaped structure is provided with four pressure relief notches 318. Four clamping ribs (not marked in the figure) extend from the two walls of the pressure relief groove slightly away from the pressure relief notch 318. The clamping ribs are connected through the clamping interface. The upwardly removable elastic sleeve 32 is provided with a pre-pressure relief hole (not shown) parallel to the axis of the pressure relief groove. The opening of the pre-pressure relief hole pointing toward the two pressure relief notches 318 is a pre-pressure relief port 316. Two stoppers 315 extend upward from the bottom of the pressure relief groove at approximately 1 / 3 and 2 / 3 of the groove's length. A gravity ball 33 is placed between the two elastic sleeves 32 and the two stoppers 315. Under the action of gravity, the gravity ball 33 can be used to block the pre-pressure relief hole and is restricted to movement within the pressure relief groove between the elastic sleeve 32 and the two stoppers 315. The gravity ball 33, elastic sleeve 32, stoppers 315, and pressure relief groove together form a complete pressure relief control assembly (not shown) with two independent pressure relief control switches (not shown). A pressure relief channel 317 extending downward from the top of the pressure relief groove is provided in the middle of the pressure relief groove, close to one side wall. In the height direction of the pressure relief filter assembly 3, the pressure relief channel extends to the bottom wall of the filter assembly 30 frame, then turns 90 degrees toward the front face where the clean water interface 301 and the exhaust interface 302 are provided, and then continues to extend toward the front face and connects to the exhaust interface 302 on the front face. The pressure relief channel 317 is provided with a downwardly recessed exhaust valve installation step 3171 at the beginning of the top of the pressure relief groove. The center of the exhaust valve installation step is provided with a pressure relief channel inlet 3172. On the passage of the pressure relief channel 317, a tubular component connecting the pressure relief channel inlet 3172 and the exhaust interface 302, having a 90-degree corner and surrounding and enclosing the entire pressure relief channel 317 is called a pressure relief channel component 3173. The gap between the exhaust valve installation step 3171 at the starting point of the pressure relief groove and the pressure relief groove formed on the pressure relief channel 317 just connects the pressure relief groove and the pressure relief channel 317.

[0103] like Figure 7 、 Figure 8As shown, the pressure to be released in the water tank first enters the pressure relief filter assembly 3 through the filter mesh 304 arranged on both sides and the bottom of the frame of the filter assembly 30, and then continues to enter the lower pressure groove through the four pressure relief notches 318. One of the two gravity balls 33 blocks the pre-pressure relief through hole in the corresponding elastic sleeve 32, and at the same time, the other gravity ball 33 opens the pre-pressure relief through hole in the corresponding elastic sleeve 32. After the pressure to be released exceeds the limit portion 315 corresponding to the gravity ball 33 corresponding to the opened pre-pressure relief through hole, it continues to enter the pressure relief channel entrance 3172 along the notch on the side wall of the pressure relief groove, and then follows the pressure relief channel 317 to the exhaust interface 302, and then is discharged out of the water tank through the exhaust port 103 of the water tank bayonet assembly 1.

[0104] like Figure 8 As shown, as a further improved implementation, an exhaust duckbill valve 34 can be further provided at the exhaust valve installation step 3171. The one-way conduction characteristic of the exhaust duckbill valve 34 can be utilized to effectively prevent the external pressure of the water tank from flowing back into the pressure relief groove through the pressure relief channel 317.

[0105] Specifically, if Figure 6 、 Figure 7 、 Figure 8 As shown, when in use, the water tank is in a moving state and basically will not be in a horizontal state for a long time. When the two pressure relief control switches are not on the same horizontal line, one of the pressure relief control switches is in a closed state, which will inevitably cause a pre-pressure relief port 316 to connect to the water tank cavity through the pressure relief channel 317, so that the pressure in the cavity can be released, thereby balancing the pressure inside and outside the water tank, and effectively reducing the negative impact of the pressure imbalance in the water tank; even when the circulating cleaning container is in a horizontal state, at this time the two pressure relief control switches are on the same horizontal line, one of the pressure relief control switches can be flushed open by the liquid in the cavity under the action of inertia, which will inevitably cause a pre-pressure relief port 316 to connect to the cavity through the pressure relief channel 317, so that the pressure in the cavity can be released, thereby balancing the pressure inside and outside the circulating cleaning container, and effectively reducing the negative impact of the pressure imbalance in the circulating cleaning container. The pressure relief control switch includes a middle gravity ball 33 , an elastic sleeve 32 that can limit the movement of the gravity ball 33 , a pre-pressure relief through hole set in the elastic sleeve 32 , and a limiter 315 that limits the moving position of the gravity ball 33 .

[0106] When the cleaner uses a cleaning roller for continuous cleaning, during the automatic cleaning process of the cleaning roller, some of the air contained in the gaps in the cleaning sponge layer of the cleaning roller is generated when the cleaning roller is squeezed and enters the cleaning liquid circuit along with the squeezed water, causing the circuit pressure to increase, resulting in low circuit liquid transportation efficiency. In severe cases, the pressure accumulated in the cleaning liquid circuit will "break open" the sealing structure of the joints, junctions and other parts in the delivery pipeline, causing the cleaning liquid circuit to "leak", seriously affecting the performance of the cleaner.

[0107] Specifically, if Figure 6 、 Figure 7 、 Figure 8 As shown, since the gravity ball 33 can move freely within the pressure relief tank, the two pressure relief control switches are set on the same horizontal line. When the two pressure relief control switches are parallel to the horizontal plane, theoretically, both pressure relief control switches may be in the closed state, the open state, or one closed and the other open. Since the water tank may only produce pressure increases when it is in use, and the water tank is in a state of motion during use, it is impossible to keep both pressure relief control switches in a horizontal state for a long time at the same time. In this case, only one of the two pressure relief control switches will be in the open state and the other will be in the closed state. This ensures that during use, at least one pre-pressure relief port 316 is connected to the outside of the water tank through the pressure relief channel 317 and the exhaust port 103, thereby achieving a pressure balance inside and outside the water tank.

[0108] like Figure 6 As shown, as a further improved implementation method, in order to better ensure that pressure balance can be achieved when the two pressure relief control switches are in the same horizontal plane, the bottom of the pressure relief groove is provided with an inclined surface (not marked in the figure) for moving the gravity ball 33 toward the pre-pressure relief port 316 and a flat horizontal surface (not marked in the figure) connecting the bottom of the inclined surface and the pre-pressure relief port 316. When the two pressure relief control switches are in the same horizontal plane, even if the gravity ball 33 makes the pre-pressure relief port 316 not conductive, the gravity ball 33 of one of the pressure relief control switches can be flushed open by the liquid in the water tank under the action of inertia, which will inevitably make it easier for the gravity ball 33 to leave the closed position of the pre-pressure relief port 316, so that one of the pre-pressure relief ports 316 will be connected to the water tank through the pressure relief channel 317, so that the pressure in the water tank can be released, thereby balancing the pressure inside and outside the water tank.

[0109] As needed, such as Figure 6 、 Figure 7 、 Figure 8 As shown, the elastic sleeve 32 can effectively reduce the noise generated by the impact of the gravity ball during movement. The elastic sleeve 32 is made of elastic materials such as silicone. The elastic sleeve 32 adopts a trumpet-shaped structure, which can achieve a better switching effect.

[0110] like Figure 1 、 Figure 2 、 Figure 9 、 Figure 10 As shown, the integrated water tank for the cleaner also includes a water tank cover assembly 4 covering the open end of the water tank body assembly (not marked in the figure), and the water tank cover assembly 4 includes a water tank cover body 40, a water tank cover outer body 41 fitted on the outside of the water tank cover body 40, and a water filling flap 42 installed on the water tank cover body 40.

[0111] Specifically, if Figure 9 、 Figure 10 As shown, one end of the water tank cover body 40 close to the water tank body assembly 2 is in an open state, and the other end is in a closed state after the water filling flap 42 is closed. The end of the water tank cover body 40 close to the water tank body assembly 2 is provided with a double-sided abutting step 401, and the section of the water tank cover body 40 close to the water tank body assembly 2 before the double-sided abutting step 401 is called the covering outer edge 402, and the outer wall of the covering outer edge 402 is elastically engaged with a covering sealing strip 403, and the covering sealing strip 403 extends outward in the direction of the inner wall of the water tank body assembly 2 with several annular sealing protrusions (not marked in the figure), and the water tank cover 4 can achieve a sealed covering of the water tank body assembly 2 through the covering sealing strip 403. The water tank cover body 40 is sleeved with the water tank cover outer body 41. The water tank cover outer body 41 is open at both ends along the axial direction of the water tank cover body 40. An abutting step 411 is provided on the inner wall of the sleeve end of the water tank cover outer body 41. The abutting step 411 abuts against the double-sided abutting steps 401 of the water tank cover body 40 and can be detachably connected to the water tank cover body 40 and the water tank cover outer body 41 by screws. Figure 9At the top of the radiator cover jacket body 41 shown, a decorative cover mounting flange 412 extends upward from the radiator cover jacket body 41, and a screw mounting hole seat (not marked in the figure) is provided in the decorative cover mounting flange 412 for screws to vertically and detachably connect the radiator cover body 40 and the radiator cover jacket body 41. A buckle (not marked in the figure) is also provided in the decorative cover mounting flange 412 for elastically snapping in the decorative cover 413. The decorative cover 413 can hide the fastening screws and serve as a beautifying decoration. The water tank cover body 40 is provided with a water injection hole 405 on the other closed end face away from the water tank body assembly 2, and the water tank cover body 40 is provided with an inner edge 406 of the water injection hole extending along the inner wall of the water injection hole 405 in the direction of the water tank body assembly 2. The water tank cover body 40 is also provided with a water injection flap installation groove 408 on the other closed end face away from the water tank body assembly 2, and the water injection flap installation shaft 421 of the water injection flap 42 can be snap-fitted into the water injection flap installation groove 408. The area of ​​the water injection flap 42 corresponding to the water injection hole 405 is provided with a covering sealing flange 422 protruding in the direction of the water injection hole, and the covering sealing flange 422 is provided with several elastic sealing rings (not marked in the figure). The water injection flap 42 can achieve the closure of the end face of the water tank cover body 40 away from the water tank body assembly 2 by sealing the inner edge 406 of the water injection hole with the covering sealing flange 422. When the water tank needs to be filled with water, the water filling cover 42 is opened and water can be poured into the water tank through the water filling hole 405. After the water filling is completed, the water filling cover 42 is closed to prevent the water in the water tank from leaking out through the water filling hole 405.

[0112] As a further improved implementation method, Figure 10 As shown, as needed, the end surface of the water tank cover body 40 away from the water tank body assembly 2 can also be provided with a snap-fit ​​hole 407. After the entire water tank is installed and fixed to the body of the vehicle cleaner, it can be snapped into the snap-fit ​​hole 407 through a buckle (not shown in the figure) provided on the body of the cleaner, thereby making the water tank more stable on the body of the cleaner.

[0113] When the water tank needs to be changed, or the pressure relief filter assembly 3 in the water tank needs deep cleaning, use external force to separate the water tank from the cleaner body, then pour out the liquid in the water tank and re-inject new liquid; or, further unplug the entire water tank cover assembly 4, further slide the handle on the pressure relief filter assembly 3 to remove the pressure relief filter assembly 3, perform deep cleaning and then install it back, and finally use external force to cover the water tank cover assembly 4 with the water tank body assembly 2 to complete this time of replacing the cleaning liquid or deep cleaning of the pressure relief filter assembly 3.
