[0041] Reference Figures 1-10, this embodiment provides an induction flushing device for external installation on a water tank 6. This induction flushing device is a device for external installation on a common toilet water tank 6, used to replace the manual pressing of the flushing button 62 on the water tank 6, so as to achieve the automatic flushing function of the common toilet water tank 6. The induction flushing device can be fixed on the water tank 6 by glue or installed on the upper cover 61 of the water tank by a detachable structure, such as Figure 10 , without changing the existing toilet, it realizes the dual-purpose automatic and manual toilet flushing, and solves the problem that the common toilet water tank 6 cannot flush automatically.

[0042] Such as Figure 2 , the induction flushing device includes a housing 1 with a chamber. The housing 1 is used to install the driving device 3 and the sensing device 2. The sensing device 2 is installed in the upper cover 11 of the housing. The sensing device 2 includes a sensing head 21, a control board 22 and a battery 23. The battery 23 uses a polymer lithium battery 23 and is charged through a charging port 24 provided on the control board 22. The charging port 24 is set as a TYPE-C charging port 24, and an opening is provided at the position of the housing 1 corresponding to the charging port 24 to facilitate the external charger of the charging port 24 to charge the battery 23. A hole plug 16 is configured at the opening. The hole plug 16 is used to cover the port of the TYPE-C charging port 24 to prevent dust, debris or other pollutants from entering the port. By adopting a rechargeable structure, it is convenient for the use and installation of the induction flushing device, eliminating the need for wiring arrangement during installation, and having a long battery life after one charge, being small, portable and easy to operate.

[0043] The control board 22 serves as the entire circuit and control system of the induction flushing device, used to connect the sensing head 21 and the driving device 3, and controls the driving device 3 through the recognition information feedback of the sensing head 21. The driving device 3 presses the flushing button 62 under the control of the control board 22, thereby realizing automatic flushing.

[0044] The sensing head 21 can be set as an infrared sensing probe or an infrared receiver. If it is set as an infrared sensing probe, wave recognition sensing can be adopted. Wave sensing can meet the technological sense requirements of most young people for automatic flushing. If it is set as an infrared receiver, a remote control can be configured for remote control. An infrared emitter is set in the remote control. The setting of the remote control can meet the alternative operations of the elderly, children, the infirm and the disabled when it is inconvenient to turn around and press or wave. Such as Figures 7-9 , the remote control can be configured with a button-type remote control 25 (including a button panel 26 and buttons 27) or a touch-type remote control 28 or an induction-type remote control to meet the specifications of various remote controls, and the induction-type remote control can also meet the setting of wave sensing at the same time.

[0045] The automatic pressing structure of the induction flushing device is arranged such that a pressing component 4 extends from one side of the housing 1. The pressing component 4 has the functions of pressing down and lifting under the drive of the drive component, and the pressing component 4 is used to simulate the action of manual pressing.

[0046] The pressing component 4 includes a driving arm 41 and a pressing arm 42. The driving arm 41 is connected to the drive component and is horizontally arranged. The pressing arm 42 is vertically connected to the driving arm 41 and is vertically arranged. The driving arm 41 can move up and down in the vertical direction under the drive of the drive component, and the pressing arm 42 realizes the functions of pressing down and lifting under the movement of the driving arm 41.

[0047] The cooperation between the driving arm 41 and the drive component is as follows: The drive component includes a reduction motor 31, a gear 32, and a slider 33. A row of teeth 34 is arranged on one side of the slider 33, and the row of teeth 34 meshes with the gear 32. The gear 32 is installed at the output end of the reduction motor 31. As the reduction motor 31 rotates, the driving gear 32 rotates, and the up-and-down linear movement of the slider 33 is realized through the meshing row of teeth 34. The driving arm 41 is fixed on the slider 33 and is driven by the slider 33 to move vertically up and down. In order to make way for the up-and-down movement of the driving arm 41, a vertical groove 17 is opened on the housing 1, and the driving arm 41 extends out of the housing 1 through the vertical groove 17.

[0048] Since the pressing arm 42 needs to press down the flushing button 62, a force will be generated on the pressing arm 42 and the driving arm 41 during pressing. Under the influence of the force, problems such as unstable meshing between the gear 32 and the row of teeth 34 of the sliding block or the gear 32 shifting and failing to mesh may occur. Therefore, a structure for limiting and stabilizing the meshing between the gear 32 and the row of teeth 34 is provided inside the housing 1.

[0049] Such as Figures 2-4, Specifically, a row of toothed guide plates 12 are vertically arranged inside the housing 1. A vertical slide rail 13 is arranged on the row of toothed guide plates 12. The slider 33 is slidably mounted on the vertical slide rail 13. The vertical slide rail 13 provides guidance for the vertical sliding of the slider 33 and ensures the stability of the vertical sliding of the slider 33. A reduction motor 31 is installed on one side of the row of toothed guide plates 12. The driving end of the reduction motor 31 passes through the row of toothed guide plates 12 to install a gear 32. The gear 32 meshes with the slider 33 mounted on the vertical slide rail 13. For the stability of the meshing of the gear 32, a gear positioning plate 14 is fixed on the row of toothed guide plates 12. The gear positioning plate 14 is fixed on one side of the vertical slide rail 13, and the gear 32 is arranged on this side. An arc-shaped groove 15 is formed on the gear positioning plate 14. The gear 32 is placed in the arc-shaped groove 15. The arc-shaped groove 15 is adapted to the size of the gear 32, and the notch of the arc-shaped groove 15 is used to make way for the meshing of the gear 32 and the row of teeth 34. During driving, the arc-shaped groove 15 limits the circumferential side of the gear 32 to prevent the gear 32 from shifting and improves the stability of meshing.

[0050] On the driving line of the gear 32 and the row of teeth 34, in order to prevent the slider 33 from moving excessively, causing the row of teeth 34 to disengage from the gear 32, resulting in the device getting stuck and unable to drive and reset, a limit switch 5 is arranged between the row of toothed guide plates 12 and the slider 33 to limit the sliding distance of the slider 33.

[0051] Such as Figure 5 , the limit switch 5 is arranged on the row of toothed guide plates 12, and the limit switch 5 is arranged on the side of the slider 33 relative to the row of teeth 34. The limit switch 5 includes a high-position contact 51 and a low-position contact. The high-position contact 51 and the low-position contact 52 are vertically fixed on the row of toothed guide plates 12, and the high-position contact 51 and the low-position contact 52 face the vertical slide rail 13. A protrusion 35 is arranged on the side of the slider 33 relative to the row of teeth 34. The protrusion 35 abuts against the high-position contact 51 or the low-position contact 52.

[0052] The limit switch 5 is electrically connected to the driving device 3. When the slider 33 moves upward or downward under the drive of the driving device 3, the protrusion 35 contacts the high-position contact 51 or the low-position contact 52. The limit switch 5 recognizes that the contact has been touched and feeds back to the driving device 3, thereby controlling the reduction motor 31 to stop rotating and the slider 33 to stop moving, so as to limit the sliding distance of the slider 33.

[0053] The flush buttons 62 of ordinary toilets come in various models and have different position heights on the water tank 6. At the same time, there are also differences in the pressing height of the flush buttons 62. Therefore, in order to be generally applicable to most ordinary toilets, in this embodiment, a height adjustment device is provided at the connection between the driving arm 41 and the pressing arm 42. This height adjustment device is used to adjust the height of the pressing arm 42. By adjusting the height between the pressing arm 42 and the flush button 62, the function of accurately pressing the flush button 62 to achieve automatic flushing can be realized.

[0054] As Figure 6 , the height adjustment device includes an adjustment joint 43 and an adjustment screw 47. The adjustment joint 43 is provided at the connection end of the pressing arm 42. A screw hole is provided at the connection end of the driving arm 41, and the adjustment screw 47 is screwed tightly into the screw hole. A vertical groove 45 is provided vertically in the adjustment joint 43, and the length of the vertical groove 45 is the adjustable height of the pressing arm 42. The installation of the pressing arm 42 and the driving arm 41 is such that the adjustment screw 47 passes through the vertical groove 45 and is locked in the screw hole, and the pressing arm 42 is fixed on the driving arm 41 under the pressing action formed by tightening the adjustment screw 47 and the vertical groove 45.

[0055] When the induction flushing device is installed on the upper cover 61 of the water tank, loosen the adjustment screw 47, and then adjust the height of the pressing arm 42 according to the distance between the pressing arm 42 and the flush button 62 and the required pressing height. After loosening the adjustment screw 47, the pressing arm 42 can move up and down relative to the adjustment screw 47 under the action of the vertical groove 45. When it moves to the required height, tighten the adjustment screw 47 inward to squeeze the vertical groove 45 and lock the pressing arm 42 at this height position.

[0056] To facilitate the installation and operation of the adjustment screw 47, a groove 44 is provided at the position corresponding to the vertical groove 45 of the adjustment joint 43, and the vertical groove 45 is provided at the bottom of the groove 44. When turning, the adjustment screw 47 is placed in the groove 44. When no operation is required, the groove 44 can be covered with the accessory decorative cover 46 to make the whole look beautiful and dust-proof.

[0057] The above is only a preferred specific embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention who makes non-substantive changes to the present invention using this concept shall fall within the scope of infringement of the protection of the present invention.
