[0024] The utility model provides a Hall type finger wave wheel structure.

[0025] like Figure 1-3 As shown, the Hall-type impeller structure provided by the embodiment of the utility model includes an inner shell 20 and an outer shell 10 that can be mounted on the inner shell 20, the outer shell 10 has an exposure opening 11 on the top, a impeller cap 30 is installed between the inner shell 20 and the outer shell 10, the impeller cap 30 partially protrudes from the exposure opening 11 and is arranged on the outer shell 10, and a rebound structure 40 is connected between the impeller cap 30 and the inner shell 20.

[0026] In this embodiment, the impeller cap 30 protruding from the housing 10 can be used to move, and when the impeller cap 30 is moved to the right position, the impeller cap 30 stops moving, and when the external force is removed, the impeller cap 30 can automatically reset itself through the rebound structure 40, thereby achieving the purpose of control. In addition, the Hall-type impeller structure provided in this application is compact and easy for users to use.

[0027] Wherein, along the length direction of the outer shell 10, both ends of the exposed opening 11 are provided with stoppers 12. When a thrust is applied forward to the impeller cap 30, the rebound structure 40 in the inner shell 20 is compressed and moves downward, and the movement stops when it moves to the stopper 12 of the outer shell 10, and at the same time, the magnet of the inner shell 20 triggers the PCBA assembly 60 to receive magnetic field feedback; when the thrust applied by the impeller cap 30 is eliminated, the rebound structure 40 in the inner shell 20 automatically returns to the center, and when a thrust is applied backward to the impeller cap 30, the rebound structure 40 in the inner shell 20 is compressed and moves downward, and the movement stops when it moves to the stopper 12 of the outer shell 10, completing a complete forward, backward and return to the center. Optionally, the rebound structure 40 can be a pre-stressed spring.

[0028] In one embodiment, the impeller cap 30 includes a mounting body 31 and a toggle portion 32 disposed on the mounting body 31, wherein the mounting body 31 is disposed between the outer shell 10 and the inner shell 20, and the toggle portion 32 is disposed protruding from the outer shell 10 from the exposure opening 11. In this embodiment, the top of the toggle portion 32 is provided with anti-slip textures to increase the friction when the user toggles and prevent slipping.

[0029] In a preferred embodiment, the left and right tilting angles of the toggle portion 32 when the toggle portion 32 is centered are both 35°. Of course, in other embodiments, the tilting angle of the toggle portion 32 can be changed by replacing the housing 10 and the toggle portion 32 .

[0030] The cross section of the mounting body 31 is in an arc shape. That is, the mounting body 31 moves in a circular motion between the outer shell 10 and the inner shell 20. And the height of the protrusion is greater than half the length of the exposure opening 11 to ensure that the protrusion can be stopped by the stopper 12.

[0031] In addition, the side wall of the inner shell 20 is provided with a positioning column 21, and the side wall of the impeller cap 30 is provided with a positioning hole 33 adapted to the positioning column 21. In this embodiment, the impeller cap 30 can be positioned and installed by the positioning column 21 and the positioning hole 33, that is, the impeller cap 30 is detachable.

[0032] The Hall-type finger wave wheel structure further includes a PCBA component 60, which is disposed below the housing 10. A mounting shell 50 is disposed below the housing 10. The mounting shell 50 has a receiving cavity 51 therein, and the PCBA component 60 is disposed in the receiving cavity 51. In this embodiment, by filling the PCBA component 60 in the receiving cavity 51, a high level of waterproofing requirements can be achieved, so that the device can operate normally underwater.

[0033] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model.
