[0021] In order to make the invention purpose, features and advantages of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the embodiments described below are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0022] Please refer to Figures 1 to 6An embodiment of the present application provides a switch structure for a handheld pool cleaner. The cleaner includes a body 100, and the switch structure is disposed on one side of the body 100. The switch structure includes a knob 200 and a control member 300. The body 100 is provided with a mounting hole 110. The control member 300 passes through the mounting hole 110 from the inner wall of the body 100, and the knob 200 is inserted into the control member 300. An elastic deformation positioning wall 310 is integrally formed and extended from the edge of the control member 300. The inner wall of the body 100 is provided with an annular wall 120 adapted to the control member 300. Two positioning grooves 121 are recessed on the side wall of the annular wall 120. The positioning wall 310 is adapted to the positioning grooves 121. A first sensing element 400 is installed on the control member 300, and a sealing sleeve 500 is installed in the inner cavity of the body 100. A second sensing element 510 is installed on the inner wall of the sealing sleeve 500. When the knob 200 is rotated and the positioning wall 310 disengages from the engagement with the positioning groove 121 and engages with the positioning groove 121 on the other side, the first sensing element 400 corresponds to the second sensing element 510 and generates a sensing, and the cleaner is adjusted to the on state.

[0023] Specifically, a switch structure is installed on one side of the body 100 to facilitate users to turn on and off the cleaning machine. The switch structure consists of a knob 200 and a control member 300. The knob 200 is arranged outside the body 100. One end of the control member 300 abuts against the inner wall of the body 100, and the other end is passed through the mounting hole 110 provided in the body 100 to form a fixed connection with the knob 200, so that when the knob 200 is rotated, the control member 300 can be driven to rotate. The positioning wall 310 extended by the integral molding of the edge of the control member 300 has a spring The inner wall of the fuselage 100 is extended with an annular wall 120 matching the edge shape of the control member 300, and the positioning groove 121 is formed by the two sides of the annular wall 120 being recessed outward, and the positioning wall 310 is snapped into the positioning groove 121 to limit the position of the control member 300; the inner cavity of the fuselage 100 is installed with a sealing sleeve 500 for sealing electronic components such as a motor, and the second sensing element 510 is arranged in the sealing sleeve 500, and the control member 300 forms a groove toward one side of the sealing sleeve 500, and the groove is A first sensing element 400 is embedded, and the first sensing element 400 and the second sensing element 510 are non-contact sensing, such as magnetic sensing, capacitive sensing, optical sensing, infrared sensing, etc., so that the second sensing element 510 receives the transmission signal to control the switch state of the cleaning machine. In the present application, the first sensing element 400 is made of a magnetic material. When the knob 200 is turned, the positioning wall 310 is disengaged from the clamping connection with the lower positioning groove 121 until it is clamped with the positioning groove 121 on the other side, the first sensing element 400 and the second sensing element 510 are in corresponding positions, and the second sensing element 510 receives the magnetic induction signal, driving the cleaning machine to start and start running; on the contrary, the knob 200 is turned in the opposite direction, when the positioning wall 310 is clamped with the positioning groove 121 at the initial end, the cleaning machine is in the closed state; through the clamping connection of the integrally formed positioning wall 310 and the positioning groove 121, the position of the switch can be quickly located when the knob 200 is turned, and it is not easy to cause deviation, which affects the effectiveness of the switch; the structure is simple and convenient for processing and maintenance.

[0024] Furthermore, the positioning wall 310 is formed by extending vertically from the edge of the control member 300 and tilting outward, and the end of the positioning wall 310 is an arc-shaped positioning protrusion 311. The edge of the control member 300 extends vertically to form a positioning wall 310 with elastic deformation, and the end of the positioning wall 310 is folded outward to form a positioning protrusion 311. The positioning protrusion 311 is arc-shaped, corresponding to the shape of the positioning groove 121. The arc-shaped positioning protrusion 311 makes the friction force during the clamping and disengagement process smaller, which is convenient for operation.

[0025] Furthermore, a reinforcing wall 320 extends vertically from the edge of the control member 300, and there is a gap between the end of the reinforcing wall 320 and the positioning wall 310. The shape of the reinforcing wall 320 corresponds to the edge of the control member 300, and there are gaps at both ends with the positioning wall 310, so that the width of the positioning wall 310 is smaller, and the whole can produce elastic deformation when stressed. Among them, the height of the reinforcing wall 320 is the same as that of the positioning wall 310, and when the knob 200 is connected to the control member 300, there is a gap between the reinforcing wall 320 and the inner wall of the fuselage 100, ensuring that when the knob 200 rotates, the control member 300 can rotate accordingly to adjust the sensing position.

[0026] Refer to Figures 3 to 6 , a connecting column 330 extends from the middle of the control member 300. The control member 300 passes through the mounting hole 110 through the connecting column 330, and the knob 200 is inserted into the connecting column 330. The connecting column 330 extends outward from the middle of the control member 300 and is generally D-shaped. One end is a plane, corresponding to the fixing column 210 extending from the middle of the knob 200, which is convenient for installation and positioning; a threaded column is provided in the middle of the connecting column 330, and the knob 200 is fixed to the threaded column of the connecting column 330 by threaded connection, with simple connection and ensuring the firm connection between the knob 200 and the control member 300.

[0027] Furthermore, a limiting block 331 is provided at the bottom of the inner cavity of the connecting column 330, and a limiting groove 211 is provided at the corresponding position of the knob 200. The limiting groove 211 is clamped to the limiting block 331. The limiting block 331 extends from one side of the threaded column in the inner cavity of the connecting column 330, and a corresponding limiting groove 211 is provided in the inner fixing column 210 of the knob 200. During installation, by clamping the limiting groove 211 to the limiting block 331, while quickly positioning, the rotation of the knob 200 can drive the control member 300 to rotate, providing double protection to prevent loosening between the knob 200 and the control member 300 and affecting the switch state.

[0028] Further, an installation groove 130 is provided on the fuselage 100, the installation hole 110 is arranged in the installation groove 130, an arc-shaped limiting wall 131 is arranged around the installation hole 110 on one side of the installation groove 130, a limiting column 220 extends from the inner side of the knob 200, and when the knob 200 rotates towards the side of the limiting wall 131, the limiting column 220 abuts against the limiting wall 131 to limit the rotation direction of the knob 200. The installation hole 110 opened in the middle of the installation groove 130 communicates with the inside and outside of the fuselage 100. The installation groove 130 is used for installing and limiting the knob 200. Both ends of the limiting wall 131 are folded inwards, so that the whole limiting wall 131 is fan-shaped. When the limiting column 220 and the knob 200 are installed, the end of the limiting column 220 is lower than the limiting wall 131. Since the limiting wall 131 is arranged on one side of the installation hole 110, when the knob 200 abuts against the side of the limiting wall 131, the limiting column 220 abuts against the limiting wall 131 to limit the rotation direction of the knob 200, and further limit the rotation angle of the knob 200, so that it is not easy to be confused when turning on and off the washing machine, which is convenient for users to use.
