[0028] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] like Figure 1 As shown, in one embodiment, a medical device is provided, comprising a host computer and a foot controller 10. The host computer and the foot controller 10 are communicatively connected, enabling communication between the host computer and the foot controller 10 to achieve signal transmission, thereby enabling control of a device such as a planing handpiece, for example, the rotational speed of a planing handpiece, a grinding handpiece, etc. Furthermore, the foot controller 10 is waterproof and highly reliable.

[0030] It should be noted that the host can be an existing component and will not be described in detail here. The medical device can be any existing device that requires the use of the foot controller 10. The communication connection can be achieved through a wired connection such as an electric wire, or through a wireless connection such as Bluetooth transmission.

[0031] like Figure 1 and Figure 2 As shown, in one embodiment, a foot controller 10 is provided, including a pedal 700 , a base 100 , a moving member 200 and a sealing assembly 300 .

[0032] like Figure 1 As shown, the base 100 can serve as the body of the entire foot controller 10, and the base 100 is provided with a mounting cavity 110 and a mounting channel 120 communicating with the mounting cavity 110. In addition, the pedal 700 is movably connected to the base 100 in the form of a hinge or a rotating shaft connection.

[0033] In one embodiment, a mounting channel 120 is provided on the left or right side of the base 100 , through which the mounting cavity 110 communicates with the outside, and the axial direction of the mounting channel 120 extends in the horizontal direction.

[0034] like Figure 1 and Figure 2As shown, the moving part 200 can be columnar or cylindrical, for example, it can be a plunger, and the moving part 200 is partially inserted into the installation channel 120. Moreover, the moving part 200 can move back and forth relative to the base 100 along the axial direction of the installation channel 120 under the drive of the pedal 700, so that the corresponding control signal can be output to the outside through the movement of the moving part 200, thereby being able to control equipment such as planing mobile phones and grinding and drilling mobile phones, for example, the rotation speed of the planing mobile phone can be controlled.

[0035] Optionally, the pedal 700 can drive the moving member 200 through interference or other means.

[0036] like Figure 2 As shown, the sealing assembly 300 is disposed between the inner side wall of the installation channel 120 and the moving member 200. Furthermore, the sealing assembly 300 is in static sealing cooperation with the inner side wall of the installation channel 120. Furthermore, the sealing assembly 300 is in dynamic sealing cooperation with the moving member 200.

[0037] In the foot controller 10 of the above embodiment, when the movable part 200 is driven by the pedal 700 and moves axially relative to the base 100 along the mounting channel 120, the static sealing cooperation between the sealing assembly 300 and the inner side wall of the mounting channel 120 and the dynamic sealing cooperation between the sealing assembly 300 and the movable part 200 will not only not affect the normal movement of the movable part 200 relative to the base 100, but also can prevent foreign matter such as water from entering the mounting cavity 110 through the mounting channel 120. The foot controller has good waterproof performance, thereby preventing the electrical components arranged in the mounting cavity 110 from being interfered with or damaged, and has high reliability.

[0038] like Figure 2 and Figure 3Shown, in one embodiment, the foot controller 10 also comprises an installation sleeve 400.Wherein, the installation sleeve 400 is sleeved on the outer sidewall of the mobile member 200, thereby utilizes the installation sleeve 400 to guide the movement of the mobile member 200, so that the movement of the mobile member 200 relative to the base 100 is more accurate and stable.The installation sleeve 400 is at least partially arranged in the installation channel 120 and is fixedly connected with the base 100 by taking modes such as plugging or clamping.And, the sealing assembly 300 comprises a first sealing member 310 and a second sealing member 320.Wherein, the first sealing member 310 is arranged between the installation sleeve 400 and the mobile member 200 so that the mobile member 200 cooperates with the installation sleeve 400 dynamic seals, can not affect the movement of the mobile member 200 relative to the base 100, also can avoid external foreign matter such as water from entering in the mounting cavity 110 by the gap between the installation sleeve 400 and the mobile member 200. The second sealing member 320 is arranged between the inner side wall of the installation channel 120 and the installation sleeve 400 to statically seal the inner side wall of the installation channel 120 and the installation sleeve 400, thereby preventing foreign matter such as water from entering the installation cavity 110 through the gap between the installation sleeve 400 and the inner side wall of the installation channel 120.

[0039] Optionally, the mounting sleeve 400 is a sleeve-shaped or cylindrical structure with both ends open.

[0040] It should be noted that the fixed connection in the embodiment of the present application can be a non-detachable connection or a detachable connection.

[0041] like Figure 2 and Figure 3 As shown, optionally, the end of the mounting sleeve 400 away from the mounting cavity 110 is provided with a flange portion 410 surrounding the outer wall of the mounting sleeve 400. Among them, the inner side wall of the mounting channel 120 is provided with a first mounting groove 121 for the flange portion 410 to be installed, and the first sealing member 310 is arranged between the flange portion 410 and the moving member 200 so that the moving member 200 and the flange portion 410 are dynamically sealed and matched, which will not affect the movement of the moving member 200 relative to the base 100, and can also prevent foreign matter such as water from entering the mounting cavity 110 through the gap between the flange portion 410 and the moving member 200. The second sealing member 320 is arranged between the inner side wall of the first mounting groove 121 and the flange portion 410 so that the inner side wall of the first mounting groove 121 and the flange portion 410 are statically sealed and matched, thereby preventing foreign matter such as water from entering the mounting cavity 110 through the gap between the flange portion 410 and the inner side wall of the first mounting groove 121.

[0042] The flange portion 410 may be in the form of an annular flange.

[0043] The first sealing member 310 may be implemented by a molded packing seal, a stuffing box seal, or an expansion ring seal, as long as it does not affect the reciprocating linear motion of the moving member 200 and ensures sufficient sealing performance.

[0044] Optionally, the cross section of the first seal 310 is X-shaped, so that the outer peripheral side wall of the first seal 310 is a tooth-like structure, which cooperates with the moving part 200 in a dynamic seal, which neither affects the reciprocating linear motion of the moving part 200 nor ensures sufficient sealing performance.

[0045] The second sealing member 320 may be implemented by an O-ring seal or a gasket seal, etc., as long as it meets sufficient sealing performance.

[0046] In one embodiment, an annular groove is formed on the circumferential side wall of the flange portion 410 for mounting the second sealing member 320 .

[0047] like Figure 2 and Figure 3 As shown, in one embodiment, the inner sidewall of the mounting sleeve 400 is provided with a second mounting groove 420. The second mounting groove 420 is arranged along the radial direction of the mounting channel 120 corresponding to the flange portion 410, and the first sealing member 310 is disposed within the second mounting groove 420. In this way, the first sealing member 310 and the second sealing member 320 can be arranged along the radial direction of the mounting channel 120 corresponding to each other, thereby achieving sealing on both sides of the mounting sleeve 400 in the radial direction, thereby improving sealing performance.

[0048] like Figure 2 As shown, in one embodiment, the foot controller 10 further includes a compression sleeve 500. The compression sleeve 500 is disposed over the outer periphery of the moving member 200 and provides a clearance fit with the moving member 200, thereby preventing the moving member 200 from reciprocating relative to the base 100. Furthermore, the compression sleeve 500 is press-fitted against the side of the flange portion 410 facing away from the mounting cavity 110. The compression sleeve 500 is fixedly connected to the base 100, thereby press-fitting the mounting sleeve 400 to the base 100, thereby preventing the mounting sleeve 400 from moving or shaking relative to the base 100.

[0049] like Figure 1As shown, in one embodiment, the foot controller 10 further includes a magnetic member 610 and a linear Hall effect sensor 620. The magnetic member 610 is connected to the movable member 200, so that the magnetic member 610 reciprocates along the axial direction of the mounting channel 120 with the movable member 200. The linear Hall effect sensor 620 is disposed on the side wall of the mounting cavity 110 away from the mounting channel 120. The linear Hall effect sensor 620 is spaced apart from the magnetic member 610. The magnetic member 610 and the linear Hall effect sensor 620 cooperate in magnetic induction within a predetermined spacing range, and the induction emphasis increases as the spacing decreases. In this way, when the magnetic member 610 moves back and forth along the axial direction of the mounting channel 120 with the movable member 200 and approaches or moves away from the linear Hall sensor 620, when the magnetic member 610 moves along the axial direction of the mounting channel 120 with the movable member 200 and approaches the linear Hall sensor 620 until it is within a preset spacing range, the magnetic member 610 and the linear Hall sensor 620 cooperate in magnetic induction to output a corresponding control signal to the outside. Moreover, as the spacing between the magnetic member 610 and the linear Hall sensor 620 becomes shorter, the induction emphasis of the magnetic induction cooperation between the magnetic member 610 and the linear Hall sensor 620 increases, thereby enhancing the control signal output to the outside, and further enhancing the control signal for the planing mobile phone and other equipment, for example, increasing the speed of the planing mobile phone. Correspondingly, when the magnetic member 610 moves along the axial direction of the mounting channel 120 with the movable member 200 and moves away from the linear Hall sensor 620 until it is outside the preset spacing range, the magnetic induction cooperation between the magnetic member 610 and the linear Hall sensor 620 disappears and the corresponding control signal cannot be output to the outside.

[0050] The magnetic component 610 may be a magnetic element such as a permanent magnet.

[0051] like Figure 1 As shown, in one embodiment, the pedal 700 includes a connecting portion 710 and a resisting portion 720 that are spaced apart. Furthermore, the connecting portion 710 is rotatably connected to the base 100 by a hinge or a rotating shaft connection, and the resisting portion 720 is in contact with the moving member 200 to drive the moving member 200 to move axially relative to the base 100 along the mounting channel 120. In this way, by stepping on the pedal 700 with the foot, the pedal 700 is rotated relative to the base 100, thereby driving the moving member 200 to move axially relative to the base 100 along the mounting channel 120, thereby causing the magnetic member 610 to approach or move away from the linear Hall sensor 620.

[0052] like Figure 1As shown, in one embodiment, the end of the moving member 200 near the contact portion 720 is provided with a contact flange 210, and the foot controller 10 further includes an elastic reset member 800. Wherein, the elastic reset member 800 is sleeved on the outer side wall of the moving member 200, one end of the elastic reset member 800 is connected to the base 100, and the other end of the elastic reset member 800 is connected to the contact flange 210. In this way, when the pedal 700 is stepped on and the moving member 200 is moved along the axial direction of the installation channel 120 along the direction of inserting into the installation cavity 110, the contact flange 210 compresses the elastic reset member 800, thereby causing the magnetic member 610 to move in the direction close to the linear Hall sensor 620; when the force of stepping on the pedal 700 disappears, the elastic reset member 800 resets, thereby pushing the moving member 200 to move along the axial direction of the installation channel 120 along the direction of pulling out from the installation cavity 110, thereby causing the magnetic member 610 to move to a reset state in the direction away from the linear Hall sensor 620.

[0053] The elastic return member 800 may be an elastic component such as a spring.

[0054] like Figure 1 As shown, in one embodiment, the interference portion 720 is further provided with a buffer member 900, which is in contact with the interference flange 210 to drive the movable member 200 to move axially relative to the base 100 along the mounting channel 120. Since the pedal 700 is generally made of a harder material such as metal, while the movable member 200 is made of a softer material, the buffer member 900 can be used to apply a force to the interference flange 210 to drive the entire movable member 200 to move axially along the mounting channel 120, thereby avoiding scratching or damaging the interference flange 210 and ensuring reliable transmission.

[0055] The buffer member 900 can be connected to the pedal 700 by plugging or snapping. The buffer member 900 can be in the form of a buffer pad or a buffer sleeve, and can be made of a flexible material such as plastic.
