For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this disclosure based on specific circumstances.

[0062] The preferred embodiments of the present disclosure are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

[0063] With reference to Figures 1-6 , according to an embodiment of the present application, a cleaning base station includes: a main housing and a dust bag holder, the dust bag holder being used to mount a dust bag, the dust bag being removably connected to the dust bag holder, the dust bag holder being disposed on the main housing and removably connected to the main housing. By making the dust bag holder removably connected to the main housing, the dust bag holder can be disassembled and maintained. In the event of extreme dust blockage requiring unclogging, the dust bag holder can be removed to create a larger maintenance operating space, reducing maintenance difficulty, improving operational convenience, and increasing maintenance efficiency. This ensures the effectiveness of the base station's maintenance of the cleaning equipment, thereby ensuring the continuity and timeliness of the cleaning equipment's operation and enhancing the user experience.

[0064] For example, when the dust collecting structure inside the main shell is severely clogged, first remove the dust bag from the bracket, and then remove the dust bag bracket from the main shell to reduce the space occupied by the dust bag bracket inside the main shell, thereby providing more operating space inside the main shell. At the same time, it can avoid scratching the hands with the sharp parts of the dust bag bracket during maintenance, thereby improving the user experience.

[0065] As an embodiment, as shown in Figures 1 to 3, the dust bag holder is connected and fixed to the main housing via fasteners. Fastening the dust bag holder to the main housing via fasteners can press the dust bag holder tightly against the main housing, preventing any gap between the dust bag holder and the main housing, ensuring that the dust bag holder is properly installed, and further preventing the dust bag holder from colliding with the main housing and causing unusual noise during vacuuming, thereby ensuring product quality after maintenance.

[0066] Furthermore, at least two fasteners are provided to fix the dust bag bracket at multiple points, thereby improving the firmness of the dust bag bracket fixation; moreover, the fasteners are arranged near the edge of the dust bag bracket to prevent the edge of the dust bag bracket from warping, thereby further improving the stability and reliability of the dust bag bracket fixation.

[0067] As shown in Figure 3, the dust bag holder is provided with a mounting hole, and the main housing is provided with a threaded hole. After the fastener passes through the mounting hole, the fastener is embedded in the threaded hole and threadedly connected with the threaded hole. By providing the threaded hole in the main housing, the dust bag holder can be pressed and fixed to the main housing by simply aligning the mounting hole and threading the fastener through the mounting hole and then threading it into the threaded hole. This makes installation quick and convenient, thereby improving the installation efficiency of the dust bag holder after maintenance and enhancing the continuity of product operation.

[0068] Specifically, the fasteners can be bolts, screws or other fasteners that meet the requirements, which can play a role in locking and preventing loosening, ensuring the firmness of the connection between the dust bag bracket and the main shell, and the fasteners can be quickly removed with common tools, making the dust bag bracket easy to disassemble and assemble and conveniently and efficiently.

[0069] As another embodiment, as shown in Figures 4 and 5, a dust collection channel is provided inside the main housing and is connected to the dust bag holder. By connecting the dust collection channel to the dust bag holder, dust in the dust collection channel can pass through the dust bag holder and enter the dust bag. After removing the dust bag holder, foreign matter in the dust collection channel can be manually cleaned to unclog the dust collection channel, ensuring smooth communication between the dust collection channel and the dust bag. This allows garbage temporarily stored in the cleaning device to be smoothly sucked into the dust bag of the cleaning base station, thereby clearing garbage inside the cleaning device and ensuring the cleaning effect of the cleaning device the next time.

[0070] In the above embodiment, as shown in Figure 1, the entrance end and the discharge end of the dust collection channel are both arranged on the main shell. When the cleaning equipment enters the base station, the entrance end can be connected with the cleaning equipment, and the discharge end is connected with the dust bag holder, thereby forming a dust collection channel inside the main shell, so that the garbage in the cleaning equipment enters the dust bag through the main shell, and the cleaning equipment is cleaned.

[0071] Furthermore, a guide channel is provided in the dust bag bracket, the air inlet of the guide channel is connected to the discharge end of the dust collecting channel, and the air outlet of the guide channel is connected to the dust bag; the guide channel is arc-shaped to prevent foreign matter from being blocked in the guide channel, ensuring that the garbage is smoothly collected into the dust bag of the base station.

[0072] As shown in Figures 4 and 5, in some embodiments, the dust collection channel is a dust collection duct. A smooth transition structure is provided on the dust collection channel to ensure a smooth transition between the dust collection channel and the main housing. This smooth transition prevents foreign matter from accumulating in blind spots in the dust collection duct, thereby preventing the duct from becoming clogged by foreign matter. This ensures that the dust collection duct remains unobstructed, allowing waste from the cleaning equipment to be smoothly drawn into the dust bag of the base station.

[0073] As shown in Figures 4 and 5, the dust collection channel includes an entry section, a guide section, and a discharge section. The entry section is arc-shaped, with the first end of the entry section connected to the main housing; the first end of the guide section is connected to the second end of the entry section to ensure a smooth transition between the guide section and the entry section; the discharge section is arc-shaped, with the first end of the discharge section connected to the second end of the guide section, and the second end of the discharge section is connected to the main housing to ensure a smooth transition between the guide section and the discharge section. By providing two arc-shaped elbows, the entry section and the discharge section, at both ends of the guide section, respectively, a smooth transition is achieved between the guide section and the main housing, avoiding dead corners in the dust collection duct, preventing the dust collection channel from being clogged due to the continuous accumulation of foreign matter in the dust collection channel, and ensuring the patency of the dust collection channel.

[0074] Furthermore, the guide section is a straight pipe, which is arranged vertically in the main shell to reduce the total length and volume of the dust collection channel, and enables the guide section to be set close to the side wall of the main shell, thereby reducing the space occupied in the main shell and reducing the overall volume of the base station.

[0075] As shown in Figure 6, after removing the dust bag bracket, the inner wall of the dust collection channel can be exposed. By removing the dust bag bracket, the inner wall of the dust collection channel can be exposed, making it easier to directly remove foreign objects blocking the dust collection channel during maintenance. Users can directly perform manual maintenance by removing the dust bag, eliminating the need for professional maintenance, eliminating the tedious after-sales process, and improving the product user experience.

[0076] Furthermore, after removing the dust bag bracket, the inner wall of the dust collection channel can be seen from the front. By exposing the inner wall of the dust collection channel from the front, it is convenient for tools to be inserted into the dust collection channel in time, making it easier for tools to reach the depth of the dust collection channel and achieving better cleaning effect.

[0077] As shown in Figures 4 to 6, the manual maintenance channel runs through the side wall of the main housing. The first end of the manual maintenance channel is connected to the dust collection channel, and the second end of the manual maintenance channel is connected to the dust bag holder, thereby connecting the dust collection channel and the dust bag holder. By adding a manual maintenance channel between the dust collection channel and the dust bag holder and passing the manual maintenance channel through the main housing, the manual maintenance channel and the dust collection channel are stably connected, ensuring a tight seal between the manual maintenance channel and the dust collection channel. The manual maintenance channel is then connected to the dust bag holder, ensuring a tight seal between the dust bag holder and the dust collection channel after the dust bag holder is installed.

[0078] Furthermore, the manual maintenance channel vertically penetrates the side wall of the main shell, so that when the dust bag holder is installed, the air inlet of the dust bag holder can be directly inserted into the manual maintenance channel, thereby connecting the dust bag holder with the dust collection channel.

[0079] As shown in Figure 6, a sealing connection is provided on the inner wall of the manual maintenance passage along its circumference. The sealing connection is used to seal the manual maintenance passage and the dust bag holder. By providing the sealing connection on the inner wall of the manual maintenance passage along its circumference, the connection between the manual maintenance passage and the dust bag holder is sealed by the sealing connection. This ensures that all dust-laden gas and debris discharged from the dust collection passage can pass through the dust bag holder and enter the dust bag, ensuring a tight seal between the dust bag holder and the manual maintenance passage and preventing secondary pollution to the environment after cleaning.

[0080] Furthermore, the sealing connection part is elastic and is arranged tightly against the inner wall of the manual maintenance channel. The sealing connection part is cylindrical and has a certain thickness, so that the guide channel of the dust bag holder fits tightly against the sealing connection part, causing the sealing connection part to produce elastic deformation, so that the air inlet is sealed and connected to the manual maintenance channel.

[0081] It should be noted that the air inlet of the guide channel can also be made to protrude from the dust bag bracket, and the inner diameter of the sealing connection part can be made equal to the outer diameter of the air inlet of the dust bag bracket. When the air inlet of the dust bag bracket is connected, the air inlet and the sealing connection part are plugged and connected and the sealing connection part is squeezed, so that the sealing connection part is tightly wrapped around the outside of the air inlet, which can further improve the sealing effect between the dust bag bracket and the dust collection channel.

[0082] Specifically, the sealing connection part can be a sealing foam, a sealing rubber pad or other sealing parts that meet the requirements.

[0083] As shown in Figures 1 to 3, the main housing is provided with a receiving slot, which is located at one end of the main housing near the dust collection channel. The receiving slot is used to place the dust bag, and the dust bag holder is embedded in the receiving slot. By locating the receiving slot on the main housing near the dust collection channel and removably securing the dust bag holder in the receiving slot, the distance between the dust bag holder and the cleaning device is reduced, thereby shortening the dust collection channel and further reducing the possibility of foreign matter clogging the dust collection channel. At the same time, it is convenient to remove foreign matter at the entrance of the dust collection channel during manual maintenance, making the operation more convenient.

[0084] In the above embodiment, the receiving groove is arranged on the front side of the main shell, and the dust bag is fixed on the dust bag bracket and placed in the receiving groove; the outer cover of the receiving groove is covered with a sealing cover plate, which is used to prevent the dust in the dust bag from overflowing, thereby ensuring the cleanliness of the base station when cleaning the cleaning equipment.

[0085] Furthermore, the dust bag holder is adapted to the shape of the accommodating groove, and the dust bag holder is detachably connected to the accommodating groove; when installing the dust bag, the edge of the dust bag holder is placed against the inner wall of the accommodating groove, and the dust bag holder is limited by the inner wall of the accommodating groove to ensure that the dust bag holder is installed in place, which facilitates fixing the dust bag holder on the main shell; moreover, by locating the dust bag holder at the edge or corner of the accommodating groove, the dust bag is prevented from being stacked on top of the dust bag holder after installation, leaving more space for the dust bag.

[0086] Specifically, the accommodating groove is a quadrilateral and the dust bag bracket is a triangle, so that the dust bag bracket can be installed in a corner of the accommodating groove. The dust bag bracket is limited by the two inner wall surfaces of the accommodating groove at the same time, thereby improving the accuracy of limiting the dust bag bracket, so that the fastener can be smoothly embedded in the threaded hole after passing through the installation hole, thereby improving the installation efficiency of the dust bag bracket.

[0087] In the above embodiment, as shown in Figure 6, a boss is provided in the accommodating groove, and the manual maintenance channel passes through the main shell and the boss at the same time. After the dust bag holder is installed, it is fixedly connected to the boss by fasteners, and the boss serves to reinforce the manual maintenance channel; moreover, by extending the manual maintenance channel, the length of the guide channel in the dust bag holder is reduced, the weight and volume of the dust bag holder are reduced, and disassembly and assembly are convenient.

[0088] Specifically, the height of the boss is smaller than the depth of the receiving groove.

[0089] In the above embodiment, as shown in Figures 1 to 3, a number of ridges are provided on the inner wall surface of the receiving groove to form a channel for gas to flow between the dust bag and the inner wall surface of the receiving groove, thereby preventing the dust bag from fitting against the inner wall surface of the receiving groove, thereby accelerating the rate of gas circulation in the dust collection channel and improving the cleaning efficiency of the cleaning equipment.

[0090] Furthermore, a ventilation hole is provided on the receiving groove, and the ridges are scattered along the circumference of the ventilation hole on the main shell to prevent the dust bag from blocking the ventilation hole and ensure the fluidity of the gas in the dust collecting channel, thereby avoiding the sudden weakening of the airflow in the dust collecting channel, causing the garbage to fall back under its own gravity and block the bottom of the dust collecting channel, further improving the anti-blocking ability of the dust collecting channel.

[0091] Furthermore, the height of the ridge gradually increases from the end away from the vent to the end close to the vent, so that the distance between the dust bag and the inner wall of the accommodating groove gradually increases, propping up the dust bag, preventing the vent from being blocked by the dust bag, and ensuring that gas can flow into the vent quickly.

[0092] With the continuous development of science and technology, smart cleaning robots have entered the lives of ordinary families and have gradually become popular.

[0093] Among current intelligent cleaning robots, there is one that can automatically mop the floor. To ensure that the robot's mop cloth remains moist, a liquid storage tank is installed inside the robot to automatically replenish cleaning fluids such as water. To facilitate smooth drainage and filling of the liquid storage tank, an overflow port is usually provided near the liquid inlet of the liquid storage tank.

[0094] However, when cleaning liquid such as water is injected into the liquid storage tank through the liquid inlet, the water tends to flow along the top wall of the liquid storage tank due to tension, causing the injected water to be easily discharged from the liquid storage tank through the overflow port, thereby preventing the liquid storage tank from being properly replenished.

[0095] In view of this, the embodiments of the present disclosure provide a cleaning equipment liquid storage tank, an automatic cleaning equipment and a cleaning base station, the main purpose of which is to avoid the cleaning liquid being discharged through the overflow port when the cleaning liquid is injected into the liquid storage tank, so that the liquid storage tank can be replenished normally.

[0096] In the description herein, a large number of specific details are provided to provide a more thorough understanding of the present disclosure. However, it will be apparent to those skilled in the art that the present disclosure can be implemented without one or more of these details. In other examples, some technical features well known in the art are not described to avoid confusion with the present disclosure.

[0097] It should be noted that the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit exemplary embodiments according to the present disclosure. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should also be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, wholes, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or combinations thereof.

[0098] Exemplary embodiments of the present disclosure will now be described in greater detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided to make the disclosure of this disclosure thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0099] As shown in Figures 7 to 10, an embodiment of the present disclosure provides a liquid storage tank for cleaning equipment, which can be applied to self-moving cleaning equipment, such as a sweeping robot, a mopping robot, a floor polishing robot or a weeding robot, etc. The liquid storage tank for cleaning equipment may include a box body 1, which includes a accommodating chamber and a liquid inlet 11, a liquid outlet 12 and an overflow port 13 respectively connected to the accommodating chamber, the liquid inlet 11 and the overflow port 13 are arranged adjacent to each other, and the accommodating chamber includes a cavity wall opposite to the liquid inlet 11; a liquid blocking member 2, which is arranged in the accommodating chamber and is located between the liquid inlet 11 and the overflow port 13, and is used to prevent the liquid flowing into the accommodating chamber from the liquid inlet 11 from flowing into the overflow port 13.

[0100] The cleaning equipment liquid storage tank provided by the embodiment of the present disclosure is equipped with a liquid blocking member 2 between the liquid inlet 11 and the overflow port 13. In this way, when a cleaning liquid such as water is injected into the accommodating cavity of the box body 1 through the liquid inlet 11, the liquid blocking member 2 can block the water flowing along the cavity wall of the accommodating cavity due to tension from entering the overflow port 13, thereby preventing the injected water from being discharged from the box body 1 through the overflow port 13, thereby ensuring the normal water replenishment of the liquid storage tank and avoiding water waste.

[0101] Specifically, the liquid inlet 11 can be set at one end of the box body 1, for injecting cleaning liquid such as water into the holding chamber of the box body 1, and the liquid outlet 12 can be set at the other end of the box body 1, for discharging the water in the holding chamber, and the overflow port 13 can be set adjacent to the liquid inlet 11, for discharging liquid when the liquid level in the holding chamber is too high, so as to maintain normal pressure in the holding chamber, and can also be used for exhausting and taking in air when the box body 1 is filled with water and drained. Specifically, when water is injected into the holding chamber from the liquid inlet 11, the holding chamber can discharge gas through the overflow port 13 to maintain the air pressure balance in the holding chamber, so that the water filling can proceed smoothly; when the box body 1 needs to drain water to the outside, a pumping device such as a water pump can be connected through the liquid outlet 12 to pump out the water in the holding chamber. During this process, the holding chamber takes in air through the overflow port 13 to maintain the air pressure balance in the holding chamber, so that the drainage can proceed smoothly.

[0102] In some embodiments, the accommodating cavity may include a cavity wall opposite to the liquid inlet 11; and the liquid blocking member 2 is connected to the cavity wall.

[0103] In the above embodiment, since the liquid blocking member 2 is connected to the cavity wall opposite to the liquid inlet 11, when the water entering the accommodating cavity from the liquid inlet 11 flows along the cavity wall due to tension, the liquid blocking member 2 can directly block the water entering from the liquid inlet 11 and flowing along the cavity wall, ensuring that the water does not flow to the overflow port 13, thereby better preventing the injected water from being discharged from the box body 1 through the overflow port 13, thereby ensuring the normal water replenishment of the liquid storage tank, and also avoiding water waste.

[0104] The liquid blocking member 2 may have various structural forms, as long as it can block the liquid flowing into the accommodating cavity from the liquid inlet 11 from flowing into the overflow port 13 .

[0105] 9 and 10 , the liquid blocking member 2 may be a plate structure, which is vertically disposed between the liquid inlet 11 and the overflow port 13 and extends along the flow direction of the liquid flowing from the liquid inlet 11 into the accommodating cavity.

[0106] In the above embodiment, the liquid blocking member 2 is a plate structure and is extended along the flow direction of the liquid flowing into the accommodating chamber from the liquid inlet 11. In this way, when the water injected into the accommodating chamber of the box body 1 through the liquid inlet 11 flows along the cavity wall opposite to the liquid inlet 11 due to tension, the water that wants to flow to the overflow port 13 can flow along the liquid blocking member 2 under the obstruction of the liquid blocking member 2, and cannot flow into the overflow port 13 on the other side of the liquid blocking member 2, thereby avoiding the water from being discharged through the overflow port 13, thereby achieving a good water blocking effect, simple structure, and reliable use.

[0107] In order to facilitate the smooth flow of water into the containing chamber of the box body 1 under the action of the liquid blocking member 2, in some embodiments, referring to Figure 9, the liquid blocking member 2 may include a first end 21 and a second end 22 arranged in sequence along the flow direction of the liquid flowing from the liquid inlet 11 into the containing chamber, and the second end 22 is bent relative to the first end 21 toward the overflow port 13.

[0108] In the above embodiment, the second end 22 of the liquid blocking member 2 is bent relative to the first end 21 thereof toward the overflow port 13, so that when water flows along the liquid blocking member 2 to the second end 22 under the obstruction of the liquid blocking member 2, the water can flow smoothly into the accommodating cavity under the guidance of the second end 22, thereby further ensuring the smooth filling of the box body 1 with water.

[0109] Furthermore, the surface of the side of the liquid blocking member 2 facing the liquid inlet 11 can be smoothly transitioned at the connection between the first end 21 and the second end 22, thereby further improving the water guiding effect of the second end 22.

[0110] In some embodiments, referring to Figures 7 and 10, the box body 1 may include a first shell 14 and a second shell 15, which are snap-fitted and connected to form a accommodating cavity of the box body 1; the liquid inlet 11, the liquid outlet 12 and the overflow port 13 are respectively arranged on the first shell 14; the inner surface of the second shell 15 is opposite to the liquid outlet 12, and the inner surface of the second shell 15 is the aforementioned cavity wall; wherein, one side of the liquid blocking part 2 can be connected to the inner surface of the second shell 15, and the other side of the liquid blocking part 2 is connected to the inner surface of the first shell 14 or there is a gap between the inner surface of the first shell 14.

[0111] In the above embodiment, the inner surface of the second shell 15 is opposite to the liquid outlet 12, and one side of the liquid blocking member 2 is connected to the inner surface of the second shell 15. In this way, when water flows along the inner surface of the second shell 15 due to tension, it can be blocked by the liquid blocking member 2 connected to the inner surface of the second shell 15, so that the water flows along the liquid blocking member 2 instead of flowing to the overflow port 13, thereby avoiding the water from being discharged through the overflow port 13.

[0112] When water is injected into the housing 1 through the liquid inlet 11, the water will flow along the inner surface of the second shell 15 due to tension. Therefore, the liquid blocking member 2 is connected to the inner surface of the second shell 15, which can prevent water from flowing to the overflow port on the other side of the liquid blocking member 2. The relationship between the liquid blocking member 2 and the first shell 14 has no effect on the liquid blocking member 2 blocking water from flowing to the overflow port 13. For example, the liquid blocking member 2 can be directly connected, indirectly connected or abutted with the inner surface of the first shell 14, or there is a gap between the liquid blocking member 2 and the inner surface of the first shell 14, which will not affect the water blocking effect of the liquid blocking member 2. Therefore, the relationship between the liquid blocking member 2 and the first shell 14 can be selected according to actual needs during specific implementation, and this application does not limit it. In order to improve the structural strength of the housing 1, the liquid blocking member 2 can be directly connected to or abutted with the inner surface of the first shell 14.

[0113] In the above embodiment, the housing 1 is formed by sealingly connecting the first shell 14 and the second shell 15, which facilitates the processing and manufacturing of the housing 1. Moreover, when the cleaning equipment liquid storage tank is in use, the first shell 14 can be located at the bottom and the second shell 15 can be located at the top to facilitate the filling and draining of the housing 1.

[0114] In some embodiments, as shown in FIG10 , the liquid blocking member 2 can be integrally connected to the second housing 15. This can improve the water blocking reliability of the liquid blocking member 2 and also improve the strength of the second housing 15, thereby improving the overall strength of the housing 1.

[0115] In some embodiments, the first housing 14 and the second housing 15 can be connected by ultrasonic welding or adhesive bonding. Ultrasonic welding not only allows the first housing 14 and the second housing 15 to be connected and assembled together, but also provides a moisture-proof and waterproof sealing effect, thereby improving the sealing between the first housing 14 and the second housing 15. Of course, the first housing 14 and the second housing 15 can also be bonded by adhesive bonding to ensure the sealing between the first housing 14 and the second housing 15.

[0116] In some embodiments, referring to Figures 8 and 10, the liquid inlet 11 may include a first tube column 111 and a second tube column 112; the first tube column 111 is located in the accommodating cavity, and one end of which is connected to the inner surface of the first shell 14; the second tube column 112 is located outside the accommodating cavity, and one end of which is connected to the outer surface of the first shell 14, and the first tube column 111 is connected to the second tube column 112; the other end of the first tube column 111 is opposite to the cavity wall.

[0117] In the above embodiment, the first tube column 111 of the liquid inlet 11 is located in the accommodating cavity, and the other end of the first tube column 111 can be located at the highest position of the accommodating cavity, that is, there can be a small distance between the other end of the first tube column 111 and the inner surface of the second shell 15 to avoid water in the accommodating cavity from flowing out due to water pressure problems, and the second tube column 112 is located outside the accommodating cavity and can be used to connect to an external water source to realize water injection into the accommodating cavity.

[0118] It can be understood that the first housing 14 defines a through hole between the first tube column 111 and the second tube column 112 to achieve communication between the first tube column 111 and the second tube column 112 .

[0119] In some embodiments, referring to Figures 8 and 10, the overflow port 13 may include a third tube column 131 and a fourth tube column 132; the third tube column 131 is located in the accommodating cavity, and one end of which is connected to the inner surface of the first shell 14, and the other end of the third tube column 131 is opposite to the cavity wall; the fourth tube column 132 is located outside the accommodating cavity, and one end of which is connected to the outer surface of the first shell 14, and the third tube column 131 is connected to the fourth tube column 132; the liquid blocking member 2 is arranged between the first tube column 111 and the third tube column 131.

[0120] In the above embodiment, the third tube column 131 of the overflow port 13 is located in the accommodating cavity, and the other end of the third tube column 131 can be located at the highest position of the accommodating cavity, that is, there can be a smaller distance between the other end of the third tube column 131 and the inner surface of the second shell 15 to avoid water in the accommodating cavity from flowing out due to water pressure problems, and the fourth tube column 132 is located outside the accommodating cavity and can be used for air intake or exhaust to achieve drainage or water injection into the accommodating cavity.

[0121] It can be understood that the first housing 14 also defines a through hole between the third tube column 131 and the fourth tube column 132 to achieve communication between the third tube column 131 and the fourth tube column 132 .
