The pressing portion 112 extends toward the circuit board 116 along the axial direction of the button 110. A human hand can press the pressing surface 111 to push the pressing portion 112 to press the switch key, thereby realizing a switch or function adjustment. Preferably, the button 110 is made of a flexible material such as rubber or silicone, so that the radial outer wall of the button 110 elastically abuts against the inner wall of the mounting hole 101. The button 110 has a receiving cavity, in which the fixing member 103 is inserted, and the radial outer wall of the fixing member 103 abuts against the radial inner wall of the button 110 and has an interference fit, so that the radial outer wall of the button 110 can press against the inner wall of the mounting hole 101 to achieve radial sealing. At the same time, the button 110 has an extension portion 113 on its radial outer edge that abuts against the inner wall of the shell 100. The pressure plate 102 is fixed to the inner wall of the shell 100. The pressure plate 102 is pressed onto one end of the button 110 where the extension portion 113 is provided. The pressure plate 102 can make the extension portion 113 press against the inner wall of the shell 100 to achieve axial sealing. No glue pouring process is required. The button 110 is sealed with the shell in the axial and radial directions through the interference fit installation structure. The structure is simple and the installation time is short, which improves production efficiency while ensuring good sealing.

[0035] Reference Figure 2 and Figure 3The radial outer side of the pressing surface 111 has a covering portion embedded in the outer wall of the housing 100, and the outer diameter of the covering portion is larger than the inner diameter of the mounting hole 101, which is beneficial to increase the area of ​​the button 110 in appearance and improve the aesthetics and convenience of observation, and the covering portion can prevent the button 110 located in the mounting hole 101 from falling out during the removal or installation process, which is beneficial to maintain the installation stability of the button 110. Optionally, a crimping portion 104 extending outward is provided on the radial outer edge of the fixing member 103, and the pressing plate 102 can press the end of the crimping portion 104 away from the button 110, so that the crimping portion 104 presses the extension portion 113, and then the extension portion 113 presses the inner wall of the housing 100. The fixing member 103 can simultaneously achieve axial sealing and radial sealing of the button 110, which is beneficial to simplify the structure and achieve quick installation. Furthermore, the crimping portion 104 can be embedded in the button 110 along the axial direction of the fixing member 103, which can further reduce the thickness in the axial direction, thereby improving the compactness of the structure and saving installation space. Optionally, a rotation stopper 115 is provided on the extension portion 113, and the rotation stopper 115 extends along the radial direction of the button 110.

[0036] Optionally, a first limiting strip 105 is provided on the inner side wall of the housing 100, and an insertion groove 109 is formed between the first limiting strip 105 and the inner wall of the housing 100. The pressure plate 102 is inserted into the insertion groove 109, and the first limiting strip 105 abuts against a side of the pressure plate 102 away from the button 110, so that the pressure plate 102 and the extension portion 113 of the button 110 maintain pressure contact, thereby achieving a stable axial seal. Furthermore, a second limiting strip 106 is provided on the inner side wall of the housing 100, and the second limiting strip 106 abuts against the two side end surfaces of the pressure plate 102, and the first limiting strip 105 is located on the second limit, so that the first limiting strip 105 and the second limiting strip 106 form an L-shaped cross-section groove, so that the pressure plate 102 can exert stable pressure contact on the button 110 to achieve a sealing effect. Optionally, refer to Figure 4 A second limit block 108 is provided on the inner wall of the housing 100, and the top of the second limit block 108 abuts against the bottom end of the pressure plate 102 to limit the pressure plate 102. During the installation process, the pressure plate 102 is inserted from the top of the plug-in slot 109 and stops when the pressure plate 102 contacts the second limit block 108, so as to facilitate the installation.

[0037] In an embodiment of the second aspect of the utility model, a cleaning machine is also provided, including the aforementioned button sealing structure, wherein axial sealing and radial sealing are achieved by setting an interference fit between the button 110 and the housing 100, without the need to use a glue injection process, which can save time and improve efficiency during the product production process, and at the same time can prevent the sealing glue from contacting the water body, and prevent the precipitation of harmful substances to cause pollution of the water body and food, so as to meet the use requirements of cleanliness and hygiene. When cleaning fruits and vegetables, the cleaning machine can be directly placed in the water body to achieve the functions of disinfection and removal of pesticide residues, and has good waterproof performance.
