Technical Field

[0001] This utility model relates to the technical field of pool cleaning machines, and in particular to the button assembly and the top cover of the pool cleaning machine. Background Technology

[0002] A pool cleaning machine is a machine that can clean stains and other dirt from the bottom or walls of a pool. To facilitate charging, pool cleaning machines are often equipped with charging components.

[0003] Since automatic pool cleaners operate underwater, their buttons may come into contact with water. To prevent water from entering the circuit board through the buttons and thus avoiding the risk of electric leakage, the button assemblies of existing automatic pool cleaners are usually sealed with potting compound, making the sealed button assembly a non-removable unit.

[0004] However, the button assembly becomes a non-removable unit after being sealed with potting compound, which increases the replacement cost of the button assembly. Utility Model Content

[0005] To address the issue of the button assembly becoming a non-removable unit after being sealed with glue, thus increasing the replacement cost of the button assembly, this utility model provides a button assembly for a swimming pool cleaner and a top cover for the swimming pool cleaner.

[0006] This utility model provides a button assembly for a swimming pool cleaning machine, adopting the following technical solution:

[0007] The button assembly of the pool cleaner includes a housing, a button block, a circuit board and a sealing ring, wherein the circuit board is installed inside the housing and the housing and the button block are detachably connected;

[0008] When the housing and the button block are pressed together, the sealing ring is located between the housing and the button block.

[0009] By adopting the above technical solution, due to the presence of the sealing ring, water will not enter the cavity formed between the button block and the housing, and the circuit board inside the cavity will not be electrically charged. A detachable connection is formed between the button block and the housing, allowing the housing and button block to be replaced and repaired separately, rather than replacing the entire button assembly, thus reducing the maintenance cost of the pool cleaning machine.

[0010] Optionally, a clamping housing is included, which clamps the outer periphery of the button block to the housing, and the clamping housing and the housing are connected by fasteners to form a detachable fixed connection.

[0011] By adopting the above technical solution, it is easy to remove the clamping shell from the housing and then separate the housing from the button block.

[0012] Optionally, the clamping shell is provided with a through hole, the button block passes through the through hole, and the protrusion of the clamping shell is inserted into the groove of the button block, and the protrusion presses the groove tightly.

[0013] By adopting the above technical solution, the clamping shell further presses the button block onto the housing, thereby enhancing the sealing performance between the housing and the button block.

[0014] Optionally, the button block includes a hard button and a soft button, with the hard button located outside the soft button;

[0015] When you press the hard button, the hard button will press the soft button, and the soft button will press the button on the circuit board.

[0016] Optionally, both the hard button and the soft button are made of silicone, with the silicone material used for the hard button being slightly harder than that used for the soft button.

[0017] By adopting the above technical solution, silicone material has good softness, elasticity and wear resistance, which enables hard buttons and soft buttons to maintain good performance under frequent pressing and harsh environments.

[0018] The top cover of the pool cleaner includes the button assembly of the pool cleaner mentioned above.

[0019] Optionally, a cover is included, wherein the housing is fixedly attached to the cover by fasteners.

[0020] By adopting the above technical solution, it is easy to remove the cover from the housing, thereby facilitating the maintenance of the button assembly.

[0021] Optionally, the cover has a perforation through which the button block passes and protrudes from the cover.

[0022] By adopting the above technical solution, it is convenient for users to press the button block.

[0023] In summary, this utility model has at least one of the following beneficial effects:

[0024] This invention, through the setting of a sealing ring, ensures that when the housing and the button block are pressed together, the sealing ring is located between the housing and the button block, preventing water from entering the cavity formed between the housing and the button block, and preventing the circuit board inside the cavity from being electrically charged. The housing and the button block form a detachable connection, allowing the housing and the button block to be replaced and repaired separately, rather than replacing the entire button assembly, thus reducing the maintenance cost of the pool cleaning machine.

[0035] The following is in conjunction with the appendix Figures 1-8 The present invention will be described in further detail below.

[0036] Please refer to the attached diagram in the instruction manual. Figure 1 , Figure 3 , Figure 4 and Figure 5This utility model provides an embodiment of a button assembly for a swimming pool cleaner, comprising a housing 2, a button block 3, a circuit board 8, and a sealing ring 9. The circuit board 8 is installed inside the housing 2, and the housing 2 and the button block 3 are detachably connected. When the housing 2 and the button block 3 are pressed together, the sealing ring 9 is located between the housing 2 and the button block 3.

[0037] Please refer to the attached diagram in the instruction manual. Figure 2 , Figure 4 and Figure 5 The device includes a clamping shell 5, which presses the outer periphery of the button block 3 against the housing 2. The clamping shell 5 and the housing 2 are detachably fixedly connected by fasteners 1. This facilitates the removal of the clamping shell 5 from the housing 2 and the disassembly of the housing 2 from the button block 3.

[0038] Please refer to the attached diagram in the instruction manual. Figure 4 and Figure 5 The clamping shell 5 has a through hole through which the button block 3 passes. The protrusion 6 of the clamping shell 5 is inserted into the groove 4 of the button block 3, and the protrusion 6 presses the groove 4 tightly. In this way, the clamping shell 5 further presses the button block 3 onto the housing 2, enhancing the sealing performance between the housing 2 and the button block 3.

[0039] Please refer to the attached diagram in the instruction manual. Figure 3 , Figure 4 , Figure 6 and Figure 7 The button block 3 includes a hard button 31 and a soft button 32. The hard button 31 is located outside the soft button 32. When the hard button 31 is pressed, it presses against the soft button 32, which in turn presses against the button 7 on the circuit board 8. Both the hard button 31 and the soft button 32 are made of silicone, but the silicone material used in the hard button 31 is harder than that used in the soft button 32. Silicone material has good flexibility, elasticity, and wear resistance, enabling the hard button 31 and the soft button 32 to maintain good performance under frequent pressing and harsh environments.

[0040] The top cover of the pool cleaner includes the button assembly of the pool cleaner mentioned above.

[0041] Please refer to the attached diagram in the instruction manual. Figure 6 , Figure 7 and Figure 8 The assembly includes a cover 10, and a housing 2 is fixedly connected to the cover 10 by fasteners 1. This facilitates the removal of the cover 10 from the housing 2, thereby making it easier to perform maintenance work on the button assembly.

[0042] Please refer to the attached diagram in the instruction manual. Figure 3 , Figure 6 and Figure 7 The cover 10 has a perforation through which the button block 3 passes and protrudes from the cover 10, making it convenient for the user to press the button block 3.

[0043] Working principle: When in use, the user presses the hard button 31, which presses the soft button 32. The soft button 32 then presses the button 7 on the circuit board 8, thus starting the pool cleaner. During the cleaning process, the housing 2 and the button block 3 are pressed together. At this time, the sealing ring 9 is located between the housing 2 and the button block 3. Thus, due to the presence of the sealing ring 9, water will not enter the cavity formed between the housing 2 and the button block 3, and the circuit board 8 in the cavity will not be electrically shocked. At the same time, the clamping shell 5 presses the outer periphery of the button block 3 against the housing 2. The clamping shell 5 is also detachably connected to the housing 2 through the fastener 1. Therefore, when the pool cleaner malfunctions, the clamping shell 5 can be removed from the housing 2, and then the housing 2 and the button block 3 can be disassembled. This allows for the separate replacement and repair of the housing 2 and the button block 3, instead of replacing the entire button assembly, thus reducing the maintenance cost of the pool cleaner.

[0044] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
