[0029] A waterproof toggle switch device for medical equipment comprises: a face shell 100, a toggle switch 200, a waterproof silica gel 500, and a detection switch 600; the toggle switch 200 is arranged inside the face shell 100, and the toggle switch 200 has a toggle portion 210, and the toggle portion 210 of the toggle switch 200 passes through the face shell 100 and is located on the surface of the face shell 100; the detection switch 600 is arranged inside the face shell 100, and is used to detect the position of the toggle switch 200; the waterproof silica gel 500 is arranged inside the face shell 100, and wraps the toggle switch 200, so as to isolate the toggle switch 200 from the electronic components inside the face shell 100 of the medical equipment.

[0030] A waterproof toggle switch device for medical equipment has a working principle as follows: a toggle switch 200, a waterproof silicone 500, and a detection switch 600 are all arranged inside a medical equipment face shell 100. A user moves (toggles) the toggle switch 200 by toggling a toggle portion 210. The detection switch 600 detects the position of the toggle switch 200, and then transmits a detection signal to a control unit (not shown in the figure). The control unit determines that the user issues / closes a control instruction (control instructions include but are not limited to: turning on / off the medical equipment, locking / unlocking the medical equipment, detecting / stopping detection, etc.) based on the detection signal of the toggle switch 200. The waterproof silicone 500 isolates the toggle switch 200 from the electronic components inside the face shell 100 of the medical equipment, thereby realizing the waterproof function of the toggle switch 200 of the medical equipment. During use, the medical equipment can be used even if there is a lot of sweat or water is accidentally poured into the hole of the toggle switch 200, thereby increasing the service life of the product.

[0031] In the present embodiment, a waterproof toggle switch device for medical equipment enables the toggle switch of the medical equipment to operate smoothly and not to get stuck easily by setting a toggle switch, waterproof silicone and a detection switch; at the same time, the waterproof function of the toggle switch of the medical equipment is realized, and the medical equipment can be used even when there is a lot of sweat or water is accidentally poured into the toggle switch hole during use, thereby improving the service life of the product; and, standardized button size requirements can be defined according to the usage scenario, travel distance and size requirements, so as to better control the cost and make it safer to use.

[0032] Specifically, the waterproof silicone 500 separates the toggle switch 200 and the detection switch 600, and the toggle switch 200 moves to squeeze the ultra-thin part of the waterproof silicone 500, and the pressure detector of the detection switch 600 detects the pressure change at the ultra-thin part of the waterproof silicone 500, and then transmits the detected pressure value signal. In this embodiment, even if liquid enters the toggle switch 200, it will not contaminate the detection switch 600 and the electronic components inside the medical device.

[0033] Specifically, the waterproof toggle switch device for medical equipment also includes a bracket 300 for supporting and limiting the toggle switch 200 , and the waterproof silicone 500 separates the toggle switch 200 , the bracket 300 and the components inside the face shell 100 .

[0034] Specifically, the waterproof toggle switch device for medical equipment further includes a spring 400 , which is assembled between the bracket 300 and the toggle switch 200 to facilitate the resetting of the toggle switch 200 and to enhance the toggle operation feel of the toggle switch 200 .

[0035] Specifically, the waterproof toggle switch device for medical equipment further includes a control screw 410 , and the control screw 410 cooperates with the bracket 300 to support and limit the toggle switch 200 .

[0036] Specifically, the waterproof toggle switch device for medical equipment further includes a control unit 700 , which is electrically connected to the detection switch 600 and is used to receive a pressure value signal sent by the detection switch 600 .

[0037] In this embodiment, the toggle switch 200 is placed in the face shell 100, and then the bracket 300 is assembled into the face shell 100 (there is an anti-fool device at the corresponding position); then the control screw 410 is locked, and the spring 400 is assembled between the bracket 300 and the toggle switch 200 (note the corresponding position), and the toggle switch 200 and the fixed part of the bracket 300 form a rotation and linkage relationship, and finally the waterproof silicone 500 is assembled on the face shell 100 to form a waterproof layer. After assembly, a semi-automatic toggle switch test module is formed; the detection switch 600 is mounted on the control unit 700 through the SMT patch, and after the silicone at the ultra-thin part of the waterproof silicone 500 is squeezed, the force will be transmitted to the detection switch 600, and the pressure detector of the detection switch 600 will transmit the pressure signal to the control unit 700, and the control unit 700 detects the pressure value exceeding the predetermined threshold value, and considers it as a start requirement, thereby realizing the trigger function.

[0038] Specifically, the control unit 700 includes a combination of one or more of an MCU, a single chip microcomputer, and a PCB board.

[0039] Specifically, the waterproof silicone 500 interferes with the surface shell 100 by 0.1 to 0.2 mm, achieving an efficient waterproof effect.

[0040] Specifically, the pressure detector of the detection switch 600 is one or more of a piezoelectric pressure sensor, a piezoresistive pressure sensor, a capacitive pressure sensor, an electromagnetic pressure sensor, and a ceramic pressure sensor.
