[0047] In some embodiments, the light display bracket 11 has an abutment surface 114 on one side facing the display screen 12. The display screen 12 is fixedly mated with the light display bracket 11 and abuts against the abutment surface 114. This arrangement allows the display screen 12 (display film) to fit snugly against the abutment surface 114 on the light display bracket 11, thereby reducing light energy loss and ensuring that light emitted by the lamp beads 130 can directly reach the display film, thereby maintaining the display quality of the display screen 12.

[0048] Optionally, the display screen 12 and the light display bracket 11 can be fixed by adhesives, snaps or clamping structures to ensure a close fit and a firm connection between the two, thereby ensuring a good display effect of the display screen 12.

[0049] In some embodiments, a first clamping portion 111 is provided on the side of the light display bracket 11 facing the circuit board 13, and a second clamping portion 131 is provided on the side of the circuit board 13 facing the light display bracket 11. The fixed assembly between the light display bracket 11 and the circuit board 13 is achieved through the clamping cooperation between the first clamping portion 111 and the second clamping portion 131.

[0050] Optionally, the first clamping portion 111 is a clamping block provided on the back of the lamp display bracket 11, and the second clamping portion 131 is a clamping slot opened on the circuit board 13. In addition, the first clamping portion 111 can also be a clamping slot opened on the lamp display bracket 11, and the second clamping portion 131 can be a clamping block provided on the circuit board 13.

[0051] In some embodiments, after the light display bracket 11 and the circuit board 13 are assembled, the side surface of the circuit board 13 facing the light display bracket 11 can be fitted with the side surface of the light display bracket 11 facing the circuit board 13 to avoid light leakage caused by a gap between the circuit board 13 and the light display bracket 11.

[0052] In some embodiments, in order to further improve the assembly stability between the light display bracket 11 and the circuit board 13, additional fasteners such as screws and bolts can be used to fix the two together to prevent the circuit board 13 from loosening or shaking during use.

[0053] See also Figures 3 to 7 , Figure 3 This is a structural diagram of the light display bracket 11 and the handle 22 after being integrally formed. Figure 4 is a schematic diagram of the structure of the cleaning device 100 near the handle 22. Figure 5 is a schematic cross-sectional view of the cleaning device 100 near the handle 22. Figure 6 yes Figure 5 A partial enlarged view of point A in the middle. Figure 7 14 is a schematic structural diagram of the key screen 14.

A button switch 132 corresponding to the key screen 14 is provided on the circuit board 13, and the key screen 14 is used to receive pressing force to trigger the button switch 132.

[0055] like Figure 3 As shown, the first mounting portion 112 and the second mounting portion 113 can be an integrally formed structure. The first mounting portion 112 and the second mounting portion 113 are both roughly plate-shaped structures. The display screen 12 and the key screen 14 are respectively covered on the first mounting portion 112 and the second mounting portion 113. When installed, the display screen 12 and the key screen 14 can be roughly seamlessly fitted, and the surfaces of the display screen 12 and the key screen 14 are flush, so as to ensure the compactness and neatness of the structure of the display module 10 and prevent dust and other debris from entering the display module 10.

[0056] A button switch 132 is provided on the side of the circuit board 13 facing the light display bracket 11. The button switch 132 corresponds to the position of the key screen 14 and is located below the key screen 14. The key screen 14 can cooperate with the button switch 132 to realize the corresponding key function. Specifically, when the user presses the key screen 14, the key screen 14 contacts the corresponding button switch 132 on the circuit board 13 under the action of the pressing force, thereby triggering the corresponding function of the button switch 132. For example, by pressing the button screen 14, the cleaning mode can be switched, the cleaning device can be started and stopped, and other functions can be realized.

[0057] In this embodiment, by dividing the display bracket 11 into zones, the keypad 14 and display screen 12 are installed on the display bracket 11, allowing the display module 10 to have both display and keypad functions. The display bracket 11 is fixedly connected to the cleaning device body 20. Therefore, during installation, the display module 10 can be assembled by simply installing the display screen 12, circuit board 13, and keypad 14 on the cleaning device body 20 corresponding to the position of the display bracket 11. This method simplifies the installation process and reduces installation costs. Furthermore, when maintaining the display module 10, individual components within the display module can be replaced independently, eliminating the need for replacing the entire module, making maintenance more convenient.

[0058] It is understood that in other embodiments, such as Figure 1 In the illustrated embodiment, the light display bracket 11 may not have the second mounting portion 113 , and correspondingly, the circuit board 13 may not be provided with the button switch 132 .

[0059] In addition, when the light display bracket 11 has a first mounting portion 112 and a second mounting portion 113, as shown in FIG. Figure 3 and Figure 4 As shown, the light-transmitting hole 110 and the abutting surface are both located in the first mounting portion 112 , and the lamp beads 130 on the circuit board 13 correspond to the first mounting portion 112 , that is, are located directly below the first mounting portion 112 .

[0060] In some embodiments, the second mounting portion 113 is provided with a first guide hole 1131 and a connecting hole 1130, and the key screen 14 includes a screen body 140, a first guide arm 141 and a resistance portion, and the first guide arm 141 and the resistance portion are respectively arranged on the side of the screen body 140 facing the light display bracket 11, and the first guide arm 141 is passed through the first guide hole 1131 and slidably cooperates with the first guide hole 1131, and the resistance portion corresponds to the position of the button switch 132. When the screen body 140 is in a pressed state, the resistance portion resists the button switch 132.

[0061] like Figure 6 and Figure 7As shown, the keypad 14 includes a screen body 140, a first guide arm 141, and a resisting portion. Optionally, the screen body 140, the first guide arm 141, and the resisting portion are integrally formed to ensure the structural strength of the keypad 14. The screen body 140 is generally plate-shaped to facilitate user pressing. The first guide arm 141 is disposed on the back of the screen body 140 and can slide up and down relative to the first guide hole 1131. The resisting portion is disposed on the back of the screen body 140 and corresponds to the position of the connecting hole 1130 and the push button switch 132. The resisting portion can contact the push button switch 132 through the connecting hole 1130 to trigger the corresponding function of the push button switch 132.

[0062] The second mounting portion 113 is provided with a first guide hole 1131 and a connecting hole 1130 that pass through the upper and lower sides of the lamp display bracket 11. Optionally, the first guide hole 1131 is located in the middle of the second mounting portion 113. The first guide hole 1131 can be a square hole or a circular hole, etc., and there is no limitation on the shape of the first guide hole 1131. The connecting hole 1130 can be provided on one side of the first guide hole 1131 and adapted to the shape of the interference portion. Optionally, the connecting hole 1130 is a circular hole.

[0063] When the user presses the screen 140 , the first guide arm 141 slides up and down along the first guide hole 1131 , causing the contact portion to move toward the button switch 132 . Thus, the contact portion contacts the button switch 132 to trigger the corresponding function of the button switch 132 .

[0064] In some embodiments, two of the interference parts, the connecting holes 1130 and the button switches 132 are respectively provided, wherein the two connecting holes 1130 are respectively located on opposite sides of the first guide hole 1131, and the interference parts and the button switches 132 respectively correspond to the positions of the corresponding connecting holes 1130. When the user presses the screen body 140, the two interference parts respectively conflict with the corresponding button switches 132 through the corresponding connecting holes 1130, thereby triggering the corresponding function of the button switch 132 while ensuring the force stability and pressing smoothness on both sides of the screen body 140, thereby avoiding smooth operation or jamming due to tilt.

[0065] In some embodiments, there are two first guide arms 141, and the two first guide arms 141 slide together with the opposite side walls of the first guide hole 1131 respectively to ensure stability and guiding accuracy when subjected to force, to ensure the alignment accuracy of the resistance part and the button switch 132, and to ensure accurate contact between the resistance part and the button switch 132.

[0066] In some embodiments, two second guide holes 1132 are further provided on the second mounting portion 113, and the two second guide holes 1132 are respectively located on opposite sides of the first guide hole 1131. The key screen 14 also includes two second guide arms 142, and the two second guide arms 142 are respectively passed through the corresponding second guide holes 1132 and slidably cooperate with the corresponding second guide holes 1132.

[0067] like Figure 3 and Figure 7 As shown, the two second guide arms 142 are fixedly connected to the back of the screen body 140, and the two second guide arms 142 are arranged opposite to each other. The two second guide arms 142 are respectively arranged on the opposite sides of the horizontal length direction of the first guide arm 141, or the two second guide arms 142 are located in the middle area formed by the two first guide arms 141 arranged horizontally and parallel. The two second guide arms 142 are clamped in the corresponding second guide holes 1132 and slide with the corresponding second guide holes 1132. In this way, through the two first guide arms 141 and the two second guide arms 142 respectively guiding and cooperating with the corresponding first guide holes 1131 and the second guide holes 1132, the four guide arms can better disperse the force, provide stronger support, and achieve more precise motion control, which helps to ensure that the key screen 14 always moves along the expected straight path, especially when subjected to lateral force, reducing the shaking or jamming of the key screen 14 during operation.

[0068] In some embodiments, the button switch 132 is a momentary switch, which can provide an elastic reset force. After the user releases the key screen 14, the key screen 14 can return to its original position under the action of the elastic reset force provided by the momentary switch.

[0069] In some embodiments, the display module 10 further includes an elastic member, which can be disposed between the second mounting portion 113 and the screen body 140. The elastic member is used to provide an elastic restoring force, and the key screen 14 can be restored to its initial position under the action of the elastic restoring force. Optionally, the elastic member is a spring or an elastic arm.

[0070] In some embodiments, a hook 1410 is provided at the bottom of the first guide arm 141, and a matching stopper groove is provided on the inner wall of the first guide hole 1131. The engagement between the stopper groove and the hook 1410 ensures that the keypad 14 will not become loose or fall off during use. It is understood that in some embodiments, a hook is also provided at the bottom of the second guide wall arm 142.

[0071] like Figure 3 and Figure 4As shown, in some embodiments, at least one rib 15 is provided on a side of the key screen 14 facing the second mounting portion 113 , and / or at least one rib 15 is provided on a side of the second mounting portion 113 facing the key screen 14 .

[0072] Specifically, the rib 15 is arranged between the key screen 14 and the second mounting portion 113, and the rib 15 is fixedly connected to the key screen 14 or the second mounting portion 113. For example, the rib 15 can be arranged on the upper surface of the second mounting portion 113, or on the back of the screen body 140. The setting of the rib 15 creates a certain gap between the key screen 14 and the upper surface of the second mounting portion 113, thereby increasing the activity of the key screen 14 and improving the flexibility of the keys.

[0073] Optionally, two ribs 15 are provided, and the two ribs 15 are arranged opposite to each other. For example, the two ribs 15 can be respectively arranged on opposite sides of the first guide hole 1131. During the pressing process, the two ribs 15 can better provide stable support for the key screen 14, further improve the flexibility and stability of the key, reduce the tilt and shaking of the screen body 140 during the pressing process, and avoid smoothness or jamming during operation.

[0074] In some embodiments, the display module 10 further includes a seal 16, which is disposed around the periphery of the button switch 132. The seal 16 is clamped between the circuit board 13 and the light display bracket 11, and the opposite ends of the seal 16 are sealed against the circuit board 13 and the light display bracket 11 respectively.

[0075] like Figure 6 As shown, the seal 16 is hollow inside, and the button switch 132 is arranged inside the seal 16. The seal 16 has a protective effect on the button switch 132 to prevent the button switch 132 from being damaged by water. The top of the seal 16 has an opening to facilitate the abutment portion to pass through the opening and abut against the button switch 132.

[0076] The seal 16 is located between the circuit board 13 and the light display bracket 11. Specifically, the seal 16 can be clamped between the circuit board 13 and the light display bracket 11 by fixing the circuit board 13 and the light display bracket 11. In this way, the two side surfaces of the seal 16 are respectively sealed against the light display bracket 11 of the circuit board 13 to prevent the circuit board 13 from being damaged by water.
