[0033] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention. Therefore, they only show the components relevant to the present invention. Orientations and references (e.g., up, down, left, right, etc.) are only used to aid in the description of the features in the drawings. Therefore, the following specific embodiments are not intended to be restrictive, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0034] like Figure 1 and Figure 2 As shown, a light-emitting soft switch button includes:

[0035] Button board 1, which is a PCB board;

[0036] A push button switch 2 is mounted on the push button board 1 and electrically connected thereto. A trigger part 201 is formed on the side of the push button switch 2 away from the push button board 1.

[0037] The light-emitting element 3 is arranged along the outer periphery of the push button switch 2 and on the push button board 1. It can change different colors according to the different states of the switch.

[0038] The button movable member 4 is movable and can press or release the trigger part 201 to realize the switch on and off. The button movable member 4 can press the trigger part 201 under the action of external force to realize conduction, and disengage from the trigger part 201 after the external force is removed to realize disconnection. The button movable member 4 has a first guide part 401.

[0039] The light guide element 5 is sleeved outside the button movable part 4 and is used to guide the light of the light-emitting element 3. The light guide element 5 is made of light-transmitting material, while the button movable part 4 and the button switch 2 are both made of opaque material. The light guide element 5 forms a second guide part 501 that cooperates with the first guide part 401. The first guide part 401 and the second guide part 501 can be a protrusion extending towards each other and a cavity for the protrusion to slide, respectively.

[0040] In this embodiment, the first guide portion 401 is formed by the button movable member 4 protruding towards the button switch 2. The first guide portion 401 has an annular structure, with one end sealed to form a pressing part 404 for the operator to press, and the other end forming an opening facing the button switch 2 to accommodate part of the button switch 2. The light guide element 5 has a generally through-tube cylindrical structure, which covers the outside of the light-emitting element 3. An inner cavity is formed inside the light guide element 5, and the button movable member 4 matches the shape of the inner cavity and is slidably disposed in the inner cavity. The second guide portion 501 is a cavity formed between the inner peripheral wall of the light guide element 5 and the outer peripheral wall of the button switch 2. The first guide portion 401 and the second guide portion 501 are slidably engaged, and the end of the second guide portion 501 that is away from the keypad 1 is sealed off. The second guide portion 501 is also a ring structure, and its shape matches the shape of the first guide portion 401. Therefore, the inner and outer peripheral walls of the first guide portion 401 are respectively attached to the key switch 2 and the light guide element 5. On the one hand, it can guide the sliding of the key movable part 4 to avoid the key movable part 4 from being skewed during the sliding process, which would cause the switch to be insensitive. On the other hand, it can prevent light from leaking out between the light guide element 5 and the key movable part 4, thereby improving the light guiding effect and making the overall structure more compact.

[0041] The cross-sectional shape of the light guide element 5 and the button movable part 4 can be, but is not limited to, square or circular. In this embodiment, it is a square structure with anti-rotation function, which can prevent the button movable part 4 from rotating circumferentially when sliding in the light guide element 5, and all four corners are rounded.

[0042] When the operator presses the button 4, the first guide part 401 and the second guide part 501 cooperate to guide the movement of the button 4. Then, the button 4 applies pressure to the trigger part 201, turning on the switch. When the operator releases their hand, the button 4 separates from the trigger part 201. At the same time, the light guide element 5 guides the light from the light-emitting element 3, making a ring of light around the button 4 illuminate. The user can directly see the position of the button structure to perform the corresponding operation. The first guide part 401 and the second guide part 501 of the button 4 cooperate to guide the movement. At the same time, it can prevent light leakage, thereby improving the light guiding effect. In addition, the light-emitting element 3 can switch different colors according to the different states of the switch to indicate different states of the device. For example, when the endoscope host is not powered on, the light-emitting element 3 does not emit light; when the host is powered on, pressing the button movable part 4 applies pressure to the trigger part 201, and the switch is fully turned on, at which time it is green; during the process of the button movable part 4 applying pressure to the trigger part 201, the switch is not fully turned on, at which time it is white. Users can intuitively know the start-up status of the device according to the color, which can avoid misoperation and thus improve the safety of endoscope use.

[0043] In some examples, such as Figure 1As shown, an elastic element 7 is provided between the button movable part 4 and the button switch 2. Preferably, the button movable part 4 and the button switch 2 are provided with a limiting step for limiting the elastic element 7 on the side that is close to each other, and the elastic element 7 rests between the two limiting steps.

[0044] The elastic element 7 can be a spring and it is always in a compressed state. When the button movable member 4 is pressed, the button movable member 4 overcomes the elastic force of the elastic element 7 and moves towards the trigger part 201 until it contacts and applies pressure to it. At this time, the switch is turned on. Then, the button movable member 4 is released and it resets under the elastic force of the elastic element 7 and separates from the trigger part 201. At this time, the elastic element 7 is still in a compressed state, but the compression is small. It presses against the button movable member 4 to position the button movable member 4.

[0045] In some examples, such as Figure 2 As shown, the trigger part 201 protrudes towards the button movable member 4 and elastically abuts against the button movable member 4. The trigger part 201 is elastic and in a compressed state. When the button movable member 4 is pressed, it overcomes the elastic force of the trigger part 201 and applies pressure to the trigger part 201, turning on the switch. After the button movable member 4 is released, it springs open under the elastic force of the trigger part 201 and returns to its initial position. At this time, the trigger part 201 is still in a compressed state, but the compression is small. It abuts against the button movable member 4 to position the button movable member 4.

[0046] The button actuator 4 includes a pressure part 402 protruding towards the button switch 2 for applying pressure to the trigger part 201. The trigger part 201 and the pressure part 402 are disposed opposite to each other. When the operator manually presses the button actuator 4, the trigger part 201 can be pressed through the pressure part 402. The pressure part 402 protrudes from the pressing part 404, and the protrusion distance of the first guide part 401 is much greater than the protrusion distance of the pressure part 402.

[0047] In some examples, such as Figure 1 and Figure 2 As shown, a limiting structure is provided between the light guide element 5 and the button movable member 4 to limit the movement stroke of the button movable member 4 to prevent it from sliding out of the light guide element 5. When the operator releases the button movable member 4, the button movable member 4 will be popped open under the elastic force of the trigger part 201. The limiting structure can prevent it from sliding out of the light guide element 5 by abutting against the button movable member 4.

[0048] In some examples, such as Figure 1 and Figure 2As shown, the limiting structure includes limiting posts 403 respectively disposed on the button movable member 4 and the light guide element 5, and limiting grooves 502 having limiting surfaces for the limiting posts 403 to slide on. In this embodiment, the limiting posts 403 protrude from the outer peripheral wall of the button movable member 4, and the limiting grooves 502 are recessed into the inner peripheral wall of the light guide element 5. When the limiting posts 403 of the button movable member 4 abut against the limiting surfaces of the limiting grooves 502, the button movable member 4 is reset, and the switch is turned off.

[0049] In some examples, there are multiple limiting structures, which are arranged at intervals along the four circumferences of the button actuator, thereby improving the stability of the entire structure.

[0050] In some examples, the light-emitting element 3 consists of several LED beads spaced circumferentially, the push-button switch 2 has a square structure, and the light-emitting element 3 has two LED beads on each side of the push-button switch 2, such as... Figure 4 As shown.

[0051] In some examples, the light-emitting element 3 is an LED light strip, which is arranged around the outside of the push-button switch 2. It can be a complete ring light strip, or it can be formed by four short light strips connected end to end. The light strip structure improves the uniformity of light output.

[0052] In some examples, light-diffusing powder is incorporated into the light guide element 5. The light-diffusing powder is added during the molding of the light guide element 5 and is evenly distributed, which can improve the uniformity of light output.

[0053] In some examples, such as Figure 3 As shown, an endoscope host includes a housing 6, on which the aforementioned luminous soft switch button is installed. Preferably, the switch button is embedded inside the housing 6, and the pressing part 404 of the switch button is flush with the wall of the housing 6 to improve the overall aesthetics of the host.

[0054] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
