[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion. The terms "first", "second", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects and not to describe a specific order.

[0041] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in connection with the embodiments can be included in at least one embodiment of this application. The phrase does not necessarily refer to the same embodiment every time it appears in the specification, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0042] An embodiment of the present invention provides a signal input device for an electronic device based on mechanical gear linkage, such as Figures 1-9 As shown, the signal input device for an electronic device based on mechanical gear linkage is applied to an electronic device and includes: a rotating disk 200 installed on the bottom case 110 of the electronic device; a transmission mechanism 300 disposed inside the bottom case 110 and rotatably connected to the rotating disk 200; an encoder 400 connected to the transmission mechanism 300; wherein, the encoder 400 converts the mechanical motion characteristics generated by the transmission mechanism 300 into electrical signals and transmits them to a circuit main board 500 disposed inside the bottom case 110 through a circuit, and the circuit main board 500 adjusts the electronic device.

[0043] It should be noted that the electronic device includes other household electrical appliances such as smart toothbrushes, dental irrigators, razors, hair dryers, and handheld vacuum cleaners, which are not limited herein.

[0044] A waterproof inner case 130 is disposed inside the bottom case 110 of the electronic device. The circuit main board 500 disposed inside the waterproof inner case 130 is electrically connected to a surface 600 disposed outside the rotating disk 200. A sealed space is formed among the surface 600, the waterproof inner case 130, and the bottom case 110. Except for the connection line between the circuit main board 500 and the encoder 400, the sealed space among the surface 600, the waterproof inner case 130, and the bottom case 110 does not contact the outside world, reducing the entry of external air moisture and improving the waterproof performance of the electronic device; wherein both the circuit main board 500 and the surface 600 are components of the electronic device and are applications of existing technologies.

[0045] The slide rail provided on the curved outer wall of the rotary disk 200 slides within the chute provided on the inner wall of the bottom shell 110. The slide rail of the rotary disk 200 and the chute on the inner wall of the bottom shell 110 are both prior arts. An end face gear 210 is provided on the lower end face of the rotary disk 200, and the end face gear 210 is hidden within the top inner edge of the bottom shell 110.

[0046] The transmission mechanism 300 includes: a rotating gear 310 that rotates within the outer knob shell 120 provided on the bottom shell 110; a transmission shaft 320 connected between the rotating gear 310 and the encoder 400. Among them, the outer edge of the rotating gear 310 is rotationally connected to the end face gear 210, the transmission shaft 320 is directly connected to the rotating shaft of the encoder 400, and the rotation of the rotary disk 200 is transmitted to the encoder 400 through the transmission mechanism 300.

[0047] In this embodiment, the encoder 400 is an optoelectronic encoder in the prior art. An optoelectronic encoder is a sensor that converts the mechanical geometric displacement on the output shaft into pulses or digital quantities through optoelectronic conversion. Different angular rotation information during the rotation process is recorded by the encoder 400 and translated into different electrical signals. The different electrical signals are transmitted to the circuit main board 500 located within the waterproof inner shell 130. The circuit main board 500 performs corresponding operations based on the corresponding information. More characteristic signals can be encoded according to the number of rotations of the rotary disk 200, and the information conversion work of the electronic device can be better completed, such as operations like switching pages, returning, and confirming. Using the rotary disk 200 to drive the encoder 400 can prevent the driving structure from directly contacting the circuit main board 500, reduce the chance of the circuit main board 500 contacting the outside world, and improve the waterproof performance of the circuit main board 500.

[0048] As a preferred implementation method in this embodiment, as Figure 3 、 Figures 5-8 shown, a sliding mechanism is provided between the transmission shaft 320 and the encoder 400. The sliding mechanism includes: a sliding plate 342 in contact connection with the high-low teeth 341 provided at the top end of the transmission shaft 320; and a chute 343 provided on the bottom shell 110 and slidably connected to the sliding plate 342.

[0049] Among them, under the rotation action of the transmission shaft 320, the uneven surface of the high-low teeth 341 pushes the sliding plate 342 sliding within the chute 343, causing different pressure values to be generated on the encoder 400 in contact connection with the sliding plate 342.

[0050] In this embodiment, the encoder 400 is a pressure encoder in the prior art; the pressure encoder can convert the pressure change value received by the upper pressure sensing module provided on the pressure encoder into a specific electrical signal. The high and low teeth 341 are in the prior art and are composed of a cylindrical structure with an uneven arc-shaped end face. The arc face will produce a pushing effect similar to that of a cam structure. The sliding plate 342 sliding in the sliding groove 343 cooperates with the arc face of the high and low teeth 341 to convert the rotational motion into a reciprocating motion; it produces an effect similar to that of a curved lever connecting rod converting rotational motion into a reciprocating motion.

[0051] The pressure sensing module of the encoder 400 is in contact connection with one end of the sliding plate 342, and the other end of the sliding plate 342 is in contact connection with the high and low teeth 341. Under the action of the transmission shaft 320, the high and low teeth 341 rotate, which will convert the rotational motion of the transmission shaft 320 into a reciprocating linear motion, thereby pushing the sliding plate 342 to move back and forth in the sliding groove 343. Different pressure values will be generated on the pressure sensing module of the encoder 400 in contact connection with the sliding plate 342 due to the back-and-forth sliding of the sliding plate 342. By regularly rotating, these pressure change values generate special electrical signals to record the number of rotation turns, enabling the encoder 400 with pressure sensing ability to know the rotation condition of the transmission shaft 320 according to the law of the pressure values, and thus transmitting different electrical signals to the circuit main board 500 to achieve the work of signal input of the electronic device.

[0052] As a preferred implementation manner in this embodiment, the side wall of the part where the sliding plate 342 slides in the sliding groove 343 is provided with a slide rail, and the ball structure 344 provided in the slide rail rolls between the sliding groove 343 and the sliding plate 342.

[0053] In this embodiment, the ball structure 344 is in the prior art, which can reduce the friction between the sliding groove 343 and the sliding plate 342, fully transmit the pressure generated by the high and low teeth 341 to push the sliding plate 342 to the pressure sensing module of the encoder 400, and reduce the error generated during the signal transmission process.

[0054] In a further preferred embodiment of the present invention, the contact surface between the sliding plate 342 and the high and low teeth 341 is arc-shaped; this improves the efficiency of the high and low teeth 341 in pushing the sliding plate 342, reduces the friction, and further reduces the error generated by the mechanical structure.

[0055] In a further preferred embodiment of the present invention, such as Figure 3 and Figure 9As shown, a prompting mechanism 700 is provided on the bottom case 110. The prompting mechanism 700 includes: a mounting base 730 fixed to the bottom case 110; a limiting ring 740 mounted on the top end of the mounting base 730; a ball 710 slidably contacting and connecting with the end face gear 210 on the inner wall of the mounting base 730; wherein, the top of a spring 720 arranged in the mounting base 730 is in contact connection with the ball 710; when the ball 710 slides on the gear face of the end face gear 210, the ball 710 reciprocates back and forth inside the mounting base 730 under the support of the spring 720.

[0056] In this embodiment, the mounting base 730 is a cylindrical structure with a circular opening on the top end face; both the spring 720 and the ball 710 are assembled in the mounting base 730. The limiting ring 740 installed at the top end of the mounting base 730 through a threaded structure is a through ring structure. The diameter of the circular opening on the upper end face of the limiting ring 740 is smaller than the diameter of the circular opening on the lower end face and also smaller than the diameter of the ball 710. When both the spring 720 and the ball 710 are assembled in the mounting base 730, the limiting ring 740 prevents the ball 710 from leaving the mounting base 730; the prompting mechanism 700 generates a sound prompt when the ball 710 slides on the gear face of the end face gear 210, which can improve the user experience while prompting the user to operate.

[0057] In a further preferred embodiment of the present invention, marking teeth are provided on the end face gear 210. When the ball 710 rotates to the marking teeth, the sound emitted by the ball 710 and the marking teeth is different from the sound emitted between other teeth.

[0058] In this embodiment, the marking teeth are prior art and are mainly made of materials different from other teeth. When the ball 710 rotates to the marking teeth and emits a sound different from other teeth, it can help the user judge the number of rotations, improve the user's control over the rotation information emitted by the rotating disk 200, and improve the control accuracy during the signal transmission process.

Secondly, those skilled in the art should also know that the embodiments described in the specification are all preferred embodiments, and the actions and modules involved are not necessarily essential to the present invention.
