Description

Technical Field

[0001] This application relates to the field of pool cleaner technology, specifically to a pool cleaner. Background Technology

[0002] In the prior art, pool cleaners are equipped with a battery box to house components such as batteries and control chips, preventing external liquids from contacting the batteries. Thus, during use, the battery box serves to prevent water damage and short circuits, ensuring that the pool cleaner can be used safely in humid environments.

[0003] Most existing pool cleaner battery compartments consist of a compartment body and a cover, with the cover connected to the compartment body for opening and closing. Inside the compartment are mounting brackets for installing the battery and control chip, ensuring their stable installation. However, this structure requires the mounting brackets to be connected inside the compartment body, increasing manufacturing complexity. Furthermore, the brackets are mostly connected to the compartment body with bolts, reducing the battery compartment's airtightness and thus compromising the safety of the pool cleaner.

[0004] Therefore, there is room for further improvement in existing pool cleaners. Utility Model Content

[0005] In view of this, and in response to the technical problems of poor sealing and low safety of the existing pool cleaners, this application provides a pool cleaner with a better sealed battery box, thereby improving the safety of the pool cleaner.

[0007] Compared with existing technologies, the pool cleaner of this application features a partition in the battery compartment, dividing the internal cavity into a first cavity and a second cavity. The first cavity is used to install the battery, and the second cavity is used to install the control board. This separates the battery and control board, preventing interference and reducing the probability of liquid seepage that could interfere with both. It also improves the relative sealing of the battery and control board cavities, thereby enhancing the safety of the pool cleaner. Furthermore, the partition allows for the installation of both the battery and control board without requiring additional connecting structures on the casing. This reduces the complexity of the internal structure, the number of mounting holes, and the structural difficulty, while improving structural strength and sealing.

[0008] Preferably, at least one partition is detachably installed inside the box; It also includes a battery holder for electrical connection to the battery; The partition includes a mounting side plate and a mounting base plate, wherein the mounting side plate is connected to the mounting base plate; The side of the mounting base plate facing the cover is the first cavity, and the other side of the mounting base plate is the second cavity; The mounting side plate is located inside the first cavity, and the battery holder is connected to the mounting side plate.

[0009] In this embodiment, by placing the battery holder on the mounting side plate, no additional connecting structure is needed inside the box to install the battery holder. This allows the partition and battery holder to be removed from or installed into the box simultaneously, reducing the installation process, simplifying the box structure, and improving the box's sealing performance.

[0010] Preferably, it further includes a first connector, through which the partition and the box body are connected; The partition plate is provided with a first mounting hole, and the box body is provided with a first mating hole.

[0012] Preferably, it also includes a second connector, through which the battery holder is connected to the partition; The partition plate has a second mounting hole on the side away from the cover, and the control plate has a second mating hole. The second mounting hole corresponds to the second mating hole for the insertion of the second connector.

[0013] In this embodiment, the second mounting hole and the second mating hole cooperate to facilitate the connection between the control board and the mounting base plate, reduce the need for control board mounting structure settings, and improve installation convenience.

[0014] Preferably, the mounting side plate is provided with a mounting groove for mounting a battery holder; It also includes a mounting block, through which the battery holder and the mounting side plate are connected; The mounting block has a fixing hole, and the battery holder has a plug hole. The plug hole corresponds to the fixing hole so that the same connector can be inserted.

[0015] In this embodiment, the mounting slot provides space for the battery holder, reducing the space occupied by the battery holder in the first cavity, while enabling the battery holder to be stably connected to the mounting side plate.

[0016] Preferably, the mounting groove is provided with a limiting hole, and the battery holder is provided with a limiting block. The limiting hole is used for the insertion of the limiting block to realize the connection between the mounting side plate and the battery holder. The box body is provided with a guide groove, and the partition is provided with a guide plate. The guide groove is used to guide the guide plate.

[0017] In this embodiment, the limiting hole and the limiting block cooperate to limit the battery holder, making it difficult for the battery holder to fall out of the mounting groove; while the guide groove and the guide block cooperate to provide guidance when the partition is installed with the box, making installation easier. At the same time, the guide block inserted into the guide groove can limit the partition relative to the box, thereby improving the installation firmness of the partition and the box.

[0018] Preferably, it also includes a handle, the handle comprising a grip portion and a fixing portion, the grip portion being connected to the fixing portion; The box body is provided with a mounting recess, and the fixing part is embedded in the mounting recess to achieve a detachable connection between the handle and the box body.

[0019] In this embodiment, the fixing part of the handle can be embedded into the mounting recess to achieve a detachable connection between the handle and the box body, making the handle and the box body a separate structure, reducing the molding difficulty of the battery box, allowing the box body to be a single structure without the need for separate parts, and further ensuring the sealing of the box body.

[0020] Preferably, the cover is provided with a first sealing groove, and a first sealing ring is provided in the first sealing groove. The first sealing ring is a hollow structure. And / or, The box body is provided with a second sealing groove, and a second sealing ring is provided in the second sealing groove. The second sealing ring is a hollow structure.

[0021] In this embodiment, the sealing ring between the box and the cover is set as a hollow structure, which has good elasticity, strong adaptability to deformation, and low cost, and can improve the sealing effect of the battery box.

[0022] Preferably, it also includes a housing, which is divided into a first housing and a second housing. The first housing and the second housing are fastened together. The first housing is provided with a drive mechanism, and the second housing is provided with a filter assembly. The first housing has a positioning protrusion that extends toward the second housing and is used to press the filter assembly.

[0023] In this embodiment, when the first housing and the second housing are fastened together, the positioning protrusion of the first housing acts on the filter assembly to press the filter assembly, thereby limiting and fixing the filter assembly. Therefore, the filter assembly can be limited without the need for an additional limiting mechanism inside the housing, reducing the structural complexity of the housing and reducing manufacturing costs.

[0024] Preferably, it also includes a rod, one end of which is connected to the battery box and the other end of which is connected to the body housing; The battery box has a wire hole at the end near the rod, and a sealing element is provided in the wire hole. The sealing element has a wire hole. The diameter of the wire hole near the end of the battery box is smaller than the diameter near the end of the body housing.

[0025] In this embodiment, the wire hole inside the seal is larger at one end and smaller at the other. The diameter of the wire hole near the end of the battery box is smaller, thereby pressing the wire inside the wire hole tightly, reducing the gap between the wire and the wire, preventing liquid from entering the battery box from the wire hole, and improving the sealing performance.

[0026] Secondly, this application provides a pool cleaner, comprising: Vacuum head; A buffer strip is provided along the length of the sidewall of the suction head.

[0027] In this embodiment, a buffer strip is provided on the side of the suction head, which can buffer the suction head when it collides with the pool side wall, reduce the probability of the suction head being damaged by direct collision with the pool side wall, and improve the service life of the pool cleaner.

[0028] Preferably, the pool cleaner includes a body housing and a battery box, one end of the body housing is connected to the battery box, and the other end of the body housing is detachably connected to the suction head.

[0029] In this embodiment, the housing and the suction head are detachably connected, which increases the ease of assembling and disassembling the suction head and the housing, and facilitates later maintenance.

[0030] Preferably, the suction head includes a socket, which has a slot on one side and a limiting insertion port on the other side; The housing includes a mounting shell, and the opposite side walls of the mounting shell are provided with mounting protrusions, one of which is disposed in the slot and the other is disposed in the limiting socket.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0037] The present application will now be described in further detail with reference to the accompanying drawings, see below. Figures 1 to 11 illustrate.

[0038] First aspect This application provides a pool cleaner 1, which is used for cleaning pools; such as Figure 1 , Figure 2 , Figure 11 As shown, the pool cleaner 1 includes a battery box 11, a rod 12, a housing 13, and a suction assembly 14. One end of the rod 12 is connected to the battery box 11, and the other end is connected to the housing 13. The end of the housing 13 away from the rod 12 is connected to the suction assembly 14. A drain outlet is provided at the end of the housing 13 closest to the rod 12. A drive mechanism 18 and a filter assembly 15 are provided inside the housing 13. The filter assembly 15 is located between the suction assembly 14 and the drain outlet. The filter assembly 15 is used to filter the liquid sucked in by the suction assembly 14, leaving dirt and impurities inside the filter assembly 15, so that the discharged liquid contains fewer impurities, thereby achieving the effect of cleaning the pool. The drive mechanism 18 is located at the end of the drain outlet away from the filter assembly 15. The drive mechanism 18 is used to provide suction to suck the solid-liquid mixture in the pool into the suction assembly 14, and then discharge it after passing through the filter assembly 15.

[0039] Specifically, such as Figure 3 , Figures 6 to 10As shown, the battery box 11 includes a box body 112, a cover 111, and a partition 113. The cover 111 is hinged at one end and fastened at the other end. The cover 111 is used to open and close the opening of the box body 112. The cover 111 has a cap-shaped structure. After the cover 111 is connected to the box body 112, an installation cavity for loading the battery 17 and the control board 19 is formed between the cover 111 and the box body 112. The battery 17 is used to supply power, and the control board 19 is used to control the operation of the entire pool cleaner 1. The battery 17 and the control board 19 are electrically connected. The partition 113 is at least one, and the partition 113 is detachably disposed inside the housing 112. The partition 113 is used to install the battery 17 and the control board 19. The partition 113 divides the mounting cavity into a first cavity 115 and a second cavity 116. The first cavity 115 is the space between the partition 113 and the cover 111, and the second cavity 116 is the space between the partition 113 and the bottom of the housing 112. The first cavity 115 is located above the second cavity 116. The battery 17 is connected to the upper end of the partition 113, and the control board 19 is connected to the lower end of the partition 113. In this embodiment, the battery 17, control board 19, and separator 113 are integrated. When installation is required, the control board 19 and separator 113 can be assembled first, then placed into the box 112, and then the battery 17 can be placed into the first cavity 115. Finally, the cover 111 can be closed. When disassembly is required, after opening the cover 111, the battery 17 can be taken away directly, and then the separator 113 can be taken away. The control board 19 is taken away with the separator 113, which simplifies the installation procedure and facilitates later maintenance.

[0040] In addition, in this embodiment, by separating the mounting cavity of the battery box 11, the battery 17 and the control board 19 are installed separately, avoiding interference between the battery 17 and the control board 19, reducing the probability of liquid seepage causing interference to both the battery 17 and the control board 19 simultaneously, and improving the relative sealing of the battery 17 cavity and the control board 19 cavity, thereby improving the safety of the pool cleaner 1. At the same time, the partition 113 can install the battery 17 and the control board 19, so that no additional connection structure is needed on the box body 112 to install the battery 17 and the control board 19, thereby reducing the structural complexity of the box body 112, reducing the number of mounting holes in the box body 112, thereby reducing the structural difficulty of the box body 112, and improving the structural strength and sealing of the box body 112.

[0041] Furthermore, the partition 113 and the battery box 11 are detachably connected, that is, the partition 113, the box body 112, and the cover 111 are separate structures. Therefore, the three can be made of different materials. In this embodiment, the partition 113 can be made of flame-retardant material, which can improve the safety of the pool cleaner 1 when the battery 17 is in use. At the same time, it is not necessary to make both the box body 112 and the cover 111 of flame-retardant material, which can control the overall manufacturing cost of the battery box 11.

[0042] In this application, as Figure 6 , Figure 10 , Figure 11 As shown, a control button is provided on the side of the box 112. The control button is electrically connected to the control board 19. The operator can control the operation status of the pool cleaner 1 through the control button.

[0043] like Figure 3 , Figures 6 to 11 As shown, the battery box 11 is further described; the battery box 11 includes a first connector and a second connector, the partition 113 is detachably connected to the box body 112 through the first connector, and the partition 113 is detachably connected to the control board 19 through the second connector. Specifically, such as Figure 7 As shown, the bottom of the partition 113 is provided with a first mounting protrusion, which protrudes towards the bottom of the box 112 and is located at the bottom corner of the partition 113; wherein, as Figure 8 As shown, the first mounting protrusion is provided with an axially penetrating first mounting hole 1135, and the box body 112 is provided with a mounting post. The mounting post protrudes towards the opening of the box body 112 and is provided with a first mating hole 1123. The first mating hole 1123 and the first mounting hole 1135 are coaxially arranged to allow the first connector to be inserted, thereby detachably connecting the partition 113 and the box body 112. like Figure 7 As shown, the bottom of the partition 113 is provided with a second mounting protrusion, which protrudes towards the bottom of the box 112 and is located in the middle of the bottom of the partition 113. The second mounting protrusion is located in the middle of the partition 113 and is provided with a second mounting hole 1136. The control plate 19 is provided with a second mating hole. The second mounting hole 1136 and the second mating hole are coaxially arranged to allow the insertion of the second connector, thereby detachably connecting the control plate 19 and the partition 113.

[0044] Furthermore, such as Figures 7 to 8As shown, the partition 113 includes a mounting side plate 1131 and a mounting base plate 1132. The bottom of the mounting side plate 1131 is connected to the side of the mounting base plate 1132. The mounting base plate 1132 is vertically connected to the mounting side plate 1131. The mounting side plate 1131 is arranged in the vertical direction, and the mounting base plate 1132 is arranged parallel to the horizontal plane. The mounting base plate 1132 is the bottom of the partition 113, so that the partition 113 forms an L-shaped structure. The mounting base plate 1132 is a rectangular plate structure, and the mounting side plate 1131 is also basically a rectangular plate structure. The upper end of the mounting base plate 1132 is a first cavity 115, and the lower end of the mounting base plate 1132 is a second cavity 116. The mounting side plate 1131 is located in the first cavity 115, and the height of the first cavity 115 in the vertical direction is greater than the height of the mounting side plate 1131. The bottom of the battery 17 is attached to the upper end of the mounting base plate 1132, and the control board 19 is connected to the bottom of the mounting base plate 1132.

[0045] Among them, such as Figure 7 As shown, there are four first mounting protrusions, which are respectively located at the four corners of the mounting base plate 1132; wherein, the two corners of the mounting base plate 1132 away from the mounting side plate 1131 are provided with outwardly flared portions to increase the structural strength at these corners.

[0046] Furthermore, such as Figure 7 As shown, there are two second mounting protrusions, symmetrically arranged; as... Figure 11 As shown, the control plate 19 has four second mating holes. The control plate 19 has a rectangular plate structure, and the four second mating holes are correspondingly located at the four corners of the control plate 19. The two second mating holes located diagonally correspond to the second mounting protrusions. Guide posts 1139 are provided on the side of the second mounting protrusions. The guide posts 1139 protrude towards the bottom of the housing 112. The outer diameter of the bottom of the guide post 1139 is smaller than the diameter of the second mating hole. There are two guide posts 1139, which are correspondingly located at the remaining two diagonally located second mating holes. When the control plate 19 is installed with the mounting base plate 1132, the control plate 19 can be connected to the guide posts 1139 according to the guidance of the guide posts 1139. Then, the second connectors are inserted into the remaining two second mating holes and the second mounting holes 1136 respectively to realize the connection between the control plate 19 and the mounting base plate 1132.

[0047] It should be noted that in this embodiment, the first mounting hole 1135, the second mounting hole 1136, the first mating hole 1123, and the second mating hole are all countersunk holes with internal threads to ensure the flatness of the upper surface of the mounting base plate 1132, to prevent the first connector from protruding outward to the surface of the mounting base plate 1132 and affecting the battery 17, or to prevent the second connector from protruding outward to the surface of the control plate 19; and the first connector and the second connector are bolts or screws.

[0048] Furthermore, such as Figures 7 to 10 As shown, the battery box 11 also includes a battery holder 114. The mounting side plate 1131 is provided with a mounting groove 1133. The mounting groove 1133 is recessed in the direction away from the mounting base plate 1132 to provide space for the battery holder 114, reduce the space occupied by the battery holder 114 in the first cavity 115, and at the same time enable the battery holder 114 to be partially inserted into the mounting groove 1133, thereby playing a certain limiting role for the battery holder 114, so that the battery holder 114 can be stably connected to the mounting side plate 1131.

[0049] Furthermore, such as Figure 8 As shown, the bottom of the mounting groove 1133 is provided with a mounting block. The mounting block has a block-shaped structure and protrudes upwards. The mounting block is provided with a fixing hole 1137. The axis of the fixing hole 1137 is parallel to the horizontal direction, and the opening of the fixing hole 1137 faces the mounting base plate 1132; Figure 9 As shown, the bottom of the battery holder 114 is provided with a socket 1142, which is coaxially arranged with the fixing hole 1137 for the same connector to be inserted, thereby realizing the connection between the battery holder 114 and the mounting side plate 1131.

[0050] like Figure 8 , Figure 9 As shown, the top of the mounting groove 1133 is provided with a limiting hole 1134, which penetrates the mounting side plate 1131; the top of the battery holder 114 is provided with a limiting block 1141, which protrudes upward toward the mounting side plate 1131. The limiting block 1141 is inserted into the limiting hole 1134, and the upper end of the limiting block 1141 forms a limit with the mounting side plate 1131 at the upper end of the limiting hole 1134, thereby enabling the battery holder 114 to connect with the mounting side plate 1131; wherein, with the cooperation of the limiting hole 1134 and the fixing hole 1137, both the upper and lower ends of the battery holder 114 are limited and fixed, and the connection stability between the battery holder 114 and the mounting side plate 1131 is good.

[0051] When installing the battery holder 114, first insert the limiting block 1141 into the limiting hole 1134 in the horizontal direction, then rotate the battery holder 114 to be parallel to the vertical direction, and push the battery holder 114 upward so that the limiting block 1141 is limited by the mounting side plate 1131. At the same time, the fixing hole 1137 is aligned with the insertion hole 1142. Then, insert bolts or screws and other connecting parts into the insertion hole 1142 and the fixing hole 1137 in sequence, and tighten them to achieve a fixed connection between the battery holder 114 and the mounting side plate 1131.

[0052] Furthermore, such as Figure 6As shown, a guide block is provided on the inner wall of the box 112. The guide block is parallel to the vertical direction and has an L-shaped structure. A guide groove 1124 is formed between the guide block and the inner wall of the box 112. Two guide blocks are provided, and the two guide blocks are arranged facing each other. Figure 7 As shown, a guide plate 1138 is provided on the side of the mounting plate 1131 away from the battery 17. The guide plate 1138 is located on both sides of the mounting groove 1133 and protrudes outward. The guide groove 1124 is used for the guide plate 1138 to be inserted to guide the partition 113, so that the partition 113 can be inserted along the guide groove 1124 to achieve precise positioning and installation.

[0053] Furthermore, the guide plate 1138 has an F-shaped structure, and the guide groove 1124 is located between the two horizontal plates, so that there is a gap between the guide groove 1124 and the inner side wall of the box 112 to accommodate the protruding part of the mounting groove 1133, while providing heat dissipation space and preventing the mounting side plate 1131 corresponding to the mounting groove 1133 from sticking to the side wall of the box 112.

[0054] Furthermore, such as Figure 8 As shown, the upper end of the mounting side plate 1131 is provided with a cover plate, which is set parallel to the mounting base plate 1132 and extends in a direction away from the mounting base plate 1132. It is used to block the upper end of the guide groove 1124 to prevent impurities from entering the guide groove 1124.

[0055] Based on any of the above embodiments, the battery box 11 can be further extended; such as... Figure 11 As shown, the pool cleaner 1 also includes a handle 16, which is detachably connected to the battery box 11. The handle 16 is used to provide a gripping part for the staff, making it easy for the staff to hold the pool cleaner 1.

[0056] The handle 16 includes a grip portion 161 and a fixing portion 162. The grip portion 161 has a C-shaped rod structure, and the fixing portion 162 has an arc-shaped sheet structure. The housing 112 has a mounting recess 1122 on the side near the rod 12. Figure 11 As shown, the mounting recess 1122 is recessed towards the center of the box 112. The mounting recess 1122 is provided with threaded holes. The fixing part 162 is nested in the mounting recess 1122. The mounting recess 1122 is provided with corresponding threaded holes. The two threaded holes are respectively for bolts or screws to be inserted, thereby realizing the detachable connection between the handle 16 and the box 112. In this embodiment, the handle 16 and the box 112 are set separately, which reduces the molding difficulty of the battery box 11 and allows the box 112 to be a whole structure without having to be set separately because of the structure of the handle 16, further ensuring the sealing of the box 112.

[0057] Based on any of the above embodiments, the battery box 11 can be further extended; such as... Figure 3 As shown, a sealing assembly is provided between the cover 111 and the box 112 to seal the connection between the cover 111 and the box 112, preventing external liquid from entering the box 112 and ensuring the airtightness of the battery box 11.

[0058] Specifically, the cover 111 is provided with a first sealing groove with the opening facing downward. The first sealing groove is provided with a first sealing ring 1111. The first sealing ring 1111 has a hollow structure. The upper end of the first sealing ring 1111 fits against the cover 111, and the lower end acts on the box 112, thereby sealing the box 112 and the cover 111.

[0059] Furthermore, the cover 111 is fitted onto the outside of the box 112. The box 112 is provided with a second sealing groove with the opening facing outward. A second sealing ring 1121 is provided inside the second sealing groove. The second sealing ring 1121 has a hollow structure. The inner side of the second sealing ring 1121 fits against the box 112, and the outer side fits against the inner side of the cover 111, thereby effectively sealing the cover 111 and the box 112.

[0060] When the sealing assembly includes both a first sealing ring 1111 and a second sealing ring 1121, that is, when the cover 111 and the box 112 are provided with both a first sealing ring 1111 and a second sealing ring 1121, the two sealing rings are distributed vertically, with the first sealing ring 1111 located above the second sealing ring 1121. Since the openings of the first sealing groove and the second sealing groove face different directions, the two seals work together to make the sealing path between the cover 111 and the box 112 more tortuous, so as to produce a tortuous seal and a better sealing effect.

[0061] Furthermore, the first sealing ring 1111 and the second sealing ring 1121 are designed as hollow structures, which have good elasticity, strong adaptability to deformation, and low cost, thus improving the sealing effect of the battery box 11.

[0062] Based on any of the above embodiments, the pool cleaner 1 can be further extended; such as... Figures 2 to 5 As shown, the housing 13 is divided into a first housing 131 and a second housing 132. The upper end of the first housing 131 is connected to the rod 12, the lower end of the first housing 131 is fastened to the upper end of the second housing 132, and the lower end of the second housing 132 is connected to the suction assembly 14. The drive mechanism 18 is located in the first housing 131, and the filter assembly 15 is located in the second housing 132.

[0063] Specifically, such as Figure 3 , Figure 5As shown, the bottom of the first housing 131 is provided with positioning protrusions 1311, and at least two positioning protrusions 1311 are provided. The two positioning protrusions 1311 are evenly spaced and extend towards the second housing 132. The bottom of the second housing 132 is provided with a water inlet 141, which protrudes upward to position and install the filter assembly 15. The bottom of the filter assembly 15 is correspondingly arranged with the water inlet 141, and the solid-liquid mixture sucked in by the suction assembly 14 can enter the filter assembly 15 through the water inlet 141. When the first housing 131 is connected to the second housing 132, the positioning protrusions 1311 abut against the upper end of the filter assembly 15, thereby pressing the filter assembly 15 so that the filter assembly 15 is relatively fixed in the second housing 132 and will not move. Therefore, in this application, it is not necessary to set an additional limiting installation structure in the second housing 132 to limit the installation of the filter assembly 15, which simplifies the structure of the second housing 132 and helps to save manufacturing costs.

[0064] In this embodiment, such as Figure 2 , Figure 4 As shown, the filter assembly 15 has a basket-shaped structure, which includes a frame and a filter screen. The frame is provided with multiple liquid outlets for liquid to flow out, but the filter screen covers the liquid outlets, so that impurities can be collected inside the filter assembly 15 and will not flow from the liquid outlets to the drain outlet.

[0065] Based on any of the above embodiments, the pool cleaner 1 can be further extended; such as... Figure 3 As shown, the end of the rod 12 near the battery box 11 is provided with a wire hole 1125 through which a power supply wire passes; wherein, a sealing element 1126 is provided inside the wire hole 1125, the sealing element 1126 is used to seal the wire and the wire hole 1125, thereby reducing the probability of liquid flowing from the rod 12 to the battery box 11 and improving the sealing performance of the battery box 11.

[0066] Furthermore, the sealing element 1126 is provided with a wire hole 1127, which has a conical structure. The diameter of the wire hole 1127 near the end of the battery box 11 is smaller than the diameter near the end of the body housing 13. That is, the upper diameter of the wire hole 1127 is small and the lower diameter is large. This allows the wire to pass smoothly into the wire hole 1127 while also reducing the gap between the wire and the wire hole 1127. This prevents liquid from entering the battery box 11 from the wire hole 1127, improving the sealing performance and the safety of the pool cleaner 1.

[0067] Second aspect This application provides a pool cleaner 1, which is used for cleaning pools, such as... Figures 12 to 15As shown, it includes a battery box 11, a suction assembly 14, and a body housing 13. One end of the body housing 13 is connected to the battery box 11, and the other end is connected to the suction assembly 14. The battery box 11 contains a battery 17, which can be used to provide power. A filter assembly 15 and a drive mechanism 18 can be installed inside the body housing 13. The drive mechanism 18 generates suction to suck up pool dirt. The dirt enters the filter assembly 15 through the suction assembly 14, and the filter assembly 15 can be used to filter the sucked dirt.

[0068] In this application, the suction assembly 14 includes a suction head 142, which is detachably connected to the housing 13; as Figures 12 to 14 As shown, the suction head 142 has a suction port 144 in the middle of its bottom. The suction head 142 generally includes four side walls, two of which are equipped with cleaning brushes 145, and the other two opposite side walls are equipped with buffer strips 143. The buffer strips 143 protrude outward and are located between the upper and lower end faces of the suction head 142. The buffer strips 143 are set along the length of the side wall of the suction head 142. When the suction head 142 collides with the side wall of the pool, the buffer strips 143 can play a role in buffering and preventing collision, reducing the probability of the suction head 142 being damaged by direct collision with the side wall of the pool, and improving the service life of the pool cleaner 1.

[0069] Among them, the buffer strip 143 has a certain degree of elasticity and deformation capability, so as to avoid easy expansion and damage under force.

[0070] Furthermore, such as Figure 14 , 15 As shown, the upper end of the suction head 142 is provided with a sleeve shell 1421, which is a cylindrical structure and corresponds to the suction port 144; the lower end of the body housing 13 is provided with a mounting shell 133, which is a cylindrical structure and is coaxially arranged with the sleeve shell 1421. The sleeve shell 1421 is sleeved on the mounting shell 133 to realize the connection between the suction head 142 and the body housing 13.

[0071] Among them, such as Figure 15 As shown, the mounting shell 133 is provided with mounting protrusions 134. Mounting protrusions 134 are provided on the two opposite outer side walls of the mounting shell 133. The two mounting protrusions 134 have the same structure. The mounting protrusions 134 extend outward. The mounting protrusions 134 are trapezoidal structures. The upper end face of the mounting protrusions 134 is parallel to the horizontal plane, and the lower end face of the mounting protrusions 134 is inclined upward.

[0072] like Figure 15As shown, the socket shell 1421 has a slot 1422 on one side and a limiting socket 1423 on the other side, that is, the slot 1422 and the limiting socket 1423 are located on opposite side walls of the socket shell 1421; wherein, the opening of the slot 1422 faces, and the limiting socket 1423 penetrates the inner and outer side walls of the socket shell 1421; when the socket shell 1421 is fitted onto the mounting shell 133, the slot 1422 first interacts with one of the mounting protrusions 134, which plays a role in positioning and guiding. At the same time, under the guidance of the lower end face of the mounting protrusion 134, the side wall of the socket shell 1421 corresponding to the limiting socket 1423 expands outward until the mounting protrusion 134 falls into the limiting socket 1423, thus realizing the limiting connection between the socket shell 1421 and the mounting shell 133.

[0073] In this embodiment, since the two mounting protrusions 134 have the same structure, the suction head 142 can be installed in either direction, improving the ease of operation.

[0074] Furthermore, the upper opening of the slot 1422 is relatively large and has a tapered outward expansion structure, so that the mounting protrusion 134 can be quickly positioned inside the slot 1422; and the bottom of the slot 1422 and the bottom of the limiting socket 1423 are on the same horizontal plane.

[0075] Furthermore, such as Figure 15 As shown, the mounting housing 133 is provided with an unlocking protrusion 1424. The unlocking protrusion 1424 protrudes outward in the horizontal direction. When it is necessary to disconnect the suction head 142 from the body housing 13, the unlocking protrusion 1424 can be pressed to apply a downward force, which can disconnect the suction head 142 from the body housing 13.

[0076] Furthermore, such as Figure 15 As shown, buffer grooves 1426 are provided on both sides of the limiting socket 1423. The buffer grooves 1426 are open at the upper end of the socket shell 1421 so that the part where the limiting socket 1423 is located can be displaced relative to other parts. When the socket shell 1421 is installed upward with the mounting shell 133, under the guidance of the lower end face of the mounting protrusion 134, the part where the limiting socket 1423 is located can expand outward, so that the socket shell 1421 and the mounting shell 133 can be installed smoothly.

[0077] The unlocking protrusion 1424 is preferably located at the upper or lower end of the limiting socket 1423 so that the limiting socket 1423 can be easily disengaged from the mounting protrusion 134.

[0078] Furthermore, such as Figure 15As shown, the inner wall of the socket 1421 corresponding to the limiting socket 1423 is provided with a relief groove 1425. The width of the relief groove 1425 is approximately the same as that of the limiting socket 1423. The relief groove 1425 is recessed outward to reduce the thickness of the socket 1421 at the limiting socket 1423, thereby reducing the difficulty of the mounting protrusion 134 pushing the socket 1421 at the limiting socket 1423, and making the installation difficulty of the suction head 142 and the body housing 13 lower.

[0079] It should be noted that this embodiment can be improved upon any of the embodiments provided in the first aspect.
