[0015] Beneficial effects of the present invention:

[0016] Through the design of the driving mechanism, when the user's finger touches the position of the infrared sensor, the electronic control unit starts the motor, and the motor drives the top transmission gear and the top drive gear to rotate through the top shaft. The top transmission gear drives the bottom shaft to rotate through the bottom transmission gear, and the bottom shaft drives the bottom drive gear to rotate synchronously, thereby driving the top drive gear and the bottom drive gear to synchronously drive the double-sided rack plate to move in the direction of the inlet and outlet, and the double-sided rack plate drives the U-shaped part to push the handle body to the outside of the shell.

[0017] Through the design of the blocking protection mechanism, the top driving gear and the bottom driving gear will synchronously drive their respective meshing single-sided rack plates to move toward the inclined plate direction. When the single-sided rack plate moves, it will drive the inclined surface block to squeeze the inclined plate. Under the extrusion and push of the inclined surface and the guide limit of the vertical slider and the vertical slide groove, the inclined plate will drive the fixed plate to move. The movement of the fixed plate and the movement of the U-shaped part are carried out synchronously.

[0018] Through the design of the buffer groove, the initial movement of the U-shaped part will not push the handle body to move. Instead, the movement of the U-shaped part is inserted into the buffer groove, and the movement of the fixed plate drives the baffle to move, so that the end of the baffle is stored from the inlet and outlet to the inside of the accommodating groove. At this time, the inclined plane block moves to the bottom of the inclined panel and only moves in a straight line along the bottom plane of the inclined panel. The straight line movement will not push the inclined panel to move. At this time, the baffle will not move and will always maintain this state, thereby facilitating the subsequent U-shaped part to push the handle body to move synchronously, so that the baffle opening the inlet and outlet is compatible with the action of the U-shaped part pushing the handle body to move.

[0019] Through the design of the positioning groove and the positioning plate, after the handle body is reset and stored in the shell, the two fixing plates will reset and move toward the position of the handle body at the same time, thereby driving the positioning plate to be inserted into the positioning groove on the handle body, thereby achieving the effect of limiting the handle body in the shell and improving the stability of the handle body.

[0020] Through the design of the rotating rod, the cleaning plate, the internal gear and the vertical rack plate, the vertical rack plate will be driven to move synchronously during the process of the end of the baffle being received from the inlet and outlet into the accommodating groove or being reset and inserted from the accommodating groove into the inlet and outlet. When the vertical rack plate moves, the rotating rod will be driven to rotate through the internal gear, and the rotation of the rotating rod will drive the cleaning plate to rotate. The rotation of the cleaning plate can sweep and clean the outer surface of the handle body.

[0021] Through the design of the shielding mechanism, in the process of the end of the above-mentioned baffle being stored from the entrance and exit to the inside of the accommodating groove one, the baffle will drive the vertical rack plate two to move synchronously, and in the process of the vertical rack plate two moving, it will drive the middle gear to rotate, and the middle gear will drive the half gear to rotate, and the half gear will drive the shielding plate to rotate, and then the shielding plate will be opened, thereby realizing the protective action of shielding the extended handle body.

[0022] Through the design of the elastic sealing strip, when the shielding mechanism is not activated, the elastic sealing strip fills the gap between the top of the receiving groove and the top of the shielding plate to prevent external water or dust from entering the interior of the receiving groove; when the shielding mechanism is activated, the rotating and opened shielding plate squeezes the elastic sealing strip without affecting the structure of the elastic sealing strip.

[0042] See also Figure 1 , Figure 2 and Fig.10 An elastic sealing strip 40 that cooperates with the baffle plate 33 is fixed to one side of the inner top of the receiving groove 2 39; through the design of the elastic sealing strip 40, when the shielding mechanism is not started, the elastic sealing strip 40 fills the gap between the top of the receiving groove 1 38 and the top of the baffle plate 33 to prevent external water or dust from entering the interior of the receiving groove 1 38. When the shielding mechanism is started, the rotating and opened baffle plate 33 squeezes the elastic sealing strip 40 without affecting the structure of the elastic sealing strip 40.

[0043] During use, when the user's finger touches the position of the infrared sensor 16, the infrared sensor 16 will transmit a signal to the electronic control unit, and the electronic control unit will start the motor 15. The motor 15 drives the top transmission gear 13 and the top drive gear 11 to rotate through the top shaft 9. The top transmission gear 13 drives the bottom shaft 10 to rotate through the bottom transmission gear 14. The bottom shaft 10 drives the bottom drive gear 12 to rotate synchronously, thereby driving the top drive gear 11 and the bottom drive gear 12 to synchronously drive the double-sided rack plate 8 to move in the direction of the inlet and outlet 37.

The movement of the fixed plate 21 and the movement of the U-shaped member 6 are performed synchronously. However, due to the existence of the buffer groove 5, the movement of the U-shaped member 6 in the early stage does not push the handle body 1 to move. Instead, the movement of the U-shaped member 6 is inserted into the buffer groove 5, and the movement of the fixed plate 21 drives the baffle 28 to move, thereby making the baffle 28 The end portion is received into the receiving groove 38 from the inlet and outlet 37. At this time, the inclined plane block 19 moves to the bottom of the inclined panel 20 and only moves linearly along the bottom plane of the inclined panel 20. The linear movement will not push the inclined panel 20 to move. At this time, the baffle 28 will not move and will always maintain this state. At this time, the two ends of the U-shaped member 6 have also been inserted into the buffer groove 5. After that, the movement of the U-shaped member 6 will push the handle body 1 to move, and the handle body 1 will pass through the inlet and outlet 37 to the outside of the shell 41. Then, the user's finger is pressed on the fingerprint identifier 34.

[0044] In the process of the end of the baffle plate 28 being received from the inlet and outlet 37 to the inside of the receiving groove 1 38, the baffle plate 28 will drive the vertical rack plate 2 30 to move synchronously, and in the process of the vertical rack plate 2 30 moving, the intermediate gear 31 will be driven to rotate, the intermediate gear 31 will drive the half gear 32 to rotate, and the half gear 32 will drive the shielding plate 33 to rotate, thereby opening the shielding plate 33 to achieve a protective action of shielding the extended handle body 1;

[0045] When the end of the baffle plate 28 is received from the inlet and outlet 37 into the accommodating groove 38 or when it is reset and inserted into the inlet and outlet 37 from the accommodating groove 38, the vertical rack plate 27 will be driven to move synchronously. When the vertical rack plate 27 moves, the rotating rod 24 will be driven to rotate through the internal gear 26. The rotation of the rotating rod 24 drives the cleaning plate 25 to rotate. The rotation of the cleaning plate 25 can sweep and clean the outer surface of the handle body 1.

[0046] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
