Description

Technical Field

[0001] This invention relates to an elevator triggering unit, an elevator control panel, and an epidemic prevention elevator, belonging to the field of safety and epidemic prevention technology for special equipment. Background Technology

[0002] When people ride elevators, they need to touch elevator buttons, which can become a carrier of viruses. Some users prepare tissues or disinfectant wipes, and some elevators provide tissue boxes to avoid direct contact between fingers and buttons. However, there is no proper recycling system for used tissues or wipes, which affects the elevator environment. Some users also use personal items such as keys to press the buttons instead of their fingers. Most users still directly touch the buttons with their fingers, which does not fundamentally solve the problem of virus transmission through indirect contact. Currently, there are methods to coat elevator buttons with films, such as the retractable antibacterial film device for elevator buttons disclosed in Chinese patent document CN112722968A. By coating elevator buttons with films and replacing the films regularly, the chance of virus transmission can be reduced, achieving the purpose of virus prevention and control. However, due to human factors, the films may not be replaced when they need to be, especially during the outbreak of highly contagious viruses such as COVID-19, which may lead to a high risk of infectious disease spread. The applicant's prior application CN112957502A discloses a contactless safety elevator for the prevention and control of the novel coronavirus, which automatically disinfects the buttons on the elevator control panel during normal use by the user. However, the structure is too complex and difficult to implement in actual application. Therefore, it is necessary to improve the structure and design a new type of epidemic prevention elevator that simplifies the button disinfection structure to facilitate its promotion and implementation. Summary of the Invention

[0003] Therefore, the purpose of this invention is to provide an elevator triggering unit, an elevator control panel, and an epidemic prevention elevator, which replaces the pop-up buttons with a toggle switch, and can disinfect the contact area after each toggle switch is moved, thereby achieving the purpose of effective epidemic prevention.

[0004] To achieve the above objectives, an elevator triggering unit of the present invention includes a housing, a tactile switch, and a toggle plate and a spray device disposed within the housing. The toggle plate includes a cylindrical portion in the middle and toggle portions on both sides of the cylindrical portion. A reciprocating cylinder, a push rod, a spindle, and a return spring are disposed within the cylindrical portion. The reciprocating cylinder is sleeved outside the spindle and keyed to the spindle. The spindle is fixed to the housing. The push rod is fixed to the reciprocating cylinder and can move towards the tactile switch to trigger the tactile switch. The return spring applies a return force to the push rod. A guide groove is provided on the outer wall of the reciprocating cylinder, and the guide grooves are connected end to end to form a winding... A closed loop of one revolution of the reciprocating cylinder; the guide groove includes four endpoints arranged in sequence, wherein the first and third endpoints are symmetrical with respect to the axis of the reciprocating cylinder, and the second and fourth endpoints are symmetrical with respect to the axis of the reciprocating cylinder; the two ends of the reciprocating cylinder are the first end and the second end, respectively, the first and third endpoints are close to the first end, and the second and fourth endpoints are close to the second end; a guide block is provided on the cylindrical part of the lever, the guide block is inserted into the guide groove, and when the guide block rotates synchronously with the lever, it can move relative to the guide groove, thereby driving the reciprocating cylinder to move linearly; the spraying device is used to spray disinfectant onto the lever part that rotates to the inside of the housing.

[0005] There are two guide blocks, and the two guide blocks are symmetrical with respect to the axis of the cylindrical part.

[0006] The tactile switch is located on the outside of the housing, and the push rod extends to the outside of the housing through the through hole; the return spring is sleeved on the outside of the push rod, with one end abutting against the protruding ring of the push rod and the other end abutting against the first mounting seat of the housing, and the push rod passes through the first mounting seat.

[0007] One end of the mandrel is provided with a prism portion, and the housing is provided with a second mounting base, the second mounting base is provided with a prism hole, and the prism portion is inserted into the prism hole.

[0008] A ratchet mechanism is also provided between the cylindrical part and the mandrel.

[0009] The ratchet mechanism includes a spring plate mounted on the cylindrical portion and a ratchet portion disposed on the spindle.

[0010] The spring is mounted on a mounting ring, which is fixed inside the cylindrical portion.

[0011] The end of the mandrel away from the prism is a insertion rod, which is inserted into a hole at the end of the top rod.

[0012] The spraying device includes a mounting base and a liquid inlet pipe connected to the mounting base. A nozzle is provided on the mounting base, and the liquid inlet pipe is used to connect to an external liquid storage device.

[0013] The present invention also provides an elevator control panel, including multiple elevator triggering units as described above and a display screen.

[0014] The present invention also provides an epidemic prevention elevator, including an elevator car and an elevator control panel as described above.

[0015] Using the above technical solution, the elevator triggering unit, elevator control panel, and epidemic prevention elevator of the present invention, when in use, press one side of the dial plate to rotate the dial plate. The rotation of the dial plate can drive the reciprocating cylinder and the top rod to move linearly, thereby pressing the tactile switch to trigger the elevator control unit to control the elevator. Furthermore, when the reciprocating cylinder and the top rod return to their original position, the dial plate can continue to rotate, causing the dial plate that was just pressed to rotate to the inside of the housing. At this time, the elevator control unit can control the spray device to spray disinfectant onto the dial plate that has entered the inside of the housing for disinfection. Simultaneously, the other dial plate rotates outward from the housing, waiting to be pressed again. Compared with the existing technology's structure that automatically disinfects the buttons on the elevator control panel during use, the elevator triggering unit, elevator control panel, and epidemic prevention elevator of the present invention are simpler, have better stability, and are very convenient for the production and processing of components and the assembly of the overall structure.

[0040] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] like Figure 1, 2 As shown, the present invention provides an elevator control panel, including multiple elevator triggering units 1 and a display screen 2.

[0042] like Figure 3-6 As shown, the elevator triggering unit 1 includes a housing 11, a tactile switch 12, a toggle plate 3, and a spray device 4. The tactile switch 12 is located on the outside of the housing 11, and the toggle plate 3 and the spray device 4 are located on the inside of the housing 11. The housing 11 is provided with an open opening 110, and the end of the toggle plate 3 can extend out of the opening 110. The user can press his / her finger on the toggle plate 3 to make the toggle plate 3 move.

[0043] like Figure 7-14 As shown, the lever 3 includes a cylindrical part 31 located in the middle and lever parts 32 located on both sides of the cylindrical part 31. A reciprocating cylinder 5, a push rod 6, a spindle 7 and a return spring 8 are provided inside the cylindrical part 31.

[0044] The reciprocating cylinder 5 is sleeved on the outside of the spindle 7. A keyway 51 is provided on the inner wall of the reciprocating cylinder 5. A key 71 that cooperates with the keyway 51 is provided on the spindle 7. The reciprocating cylinder 5 and the spindle 7 are connected by a key, so that they can move relative to each other along the axial direction, but cannot rotate relative to each other.

[0045] A second mounting base 112 is provided on the housing 11. The second mounting base 112 is provided with a prism hole. One end of the mandrel 7 is provided with a prism portion 72. The prism portion 72 is inserted into the prism hole, thereby fixing the mandrel 7 on the housing 11.

[0046] The push rod 6 is fixed to the reciprocating cylinder 5. The push rod 6 can move towards the tactile switch 12 to trigger the tactile switch 12. The reset spring 8 is used to apply a reset force to the push rod 6.

[0047] A guide groove 52 is provided on the outer wall of the reciprocating cylinder 5. The guide groove 52 is connected end to end to form a closed loop around the reciprocating cylinder 5, but the closed loop is not a circular ring. Specifically, the guide groove 52 includes four endpoints arranged in sequence, wherein the first endpoint 521 and the third endpoint 523 are symmetrical with respect to the axis of the reciprocating cylinder 5, and the second endpoint 522 and the fourth endpoint 524 are symmetrical with respect to the axis of the reciprocating cylinder 5. The two ends of the reciprocating cylinder 5 are the first end 5a and the second end 5b, respectively. The first endpoint 521 and the third endpoint 523 are close to the first end 5a, and the second endpoint 522 and the fourth endpoint 524 are close to the second end 5b. Therefore, the guide groove 52 is formed into four segments: a first segment located between the first endpoint 521 and the second endpoint 522; a second segment located between the second endpoint 522 and the third endpoint 523; a third segment located between the third endpoint 523 and the fourth endpoint 524; and a fourth segment located between the fourth endpoint 524 and the first endpoint 521. Adjacent segments bend at a common endpoint; for example, the first segment bends at the second endpoint 522. The portions of the guide groove 52 at each endpoint transition smoothly.

[0048] A guide block 90 is provided on the cylindrical part 31 of the dial plate 3. The guide block 90 is inserted into the guide groove 52. When the guide block 90 rotates synchronously with the dial plate 3, it can move relative to the guide groove 52, thereby driving the reciprocating cylinder 5 to move linearly.

[0049] In this embodiment, there are two guide blocks 90, and the two guide blocks 90 are symmetrical with respect to the axis of the cylindrical part 31.

[0050] A first mounting base 111 is also provided on the housing 11. The push rod 6 extends to the outside of the housing 11 after passing through the first mounting base 111 and the through hole on the housing 11. The return spring 8 is sleeved on the outside of the push rod 6, with one end abutting against the protruding ring portion 61 of the push rod 6 and the other end abutting against the first mounting base 111 of the housing 11. The protruding ring portion 61 is fixed to the reciprocating cylinder 5 by screws.

[0051] The end of the mandrel 7 furthest from the prism portion 72 is a insertion rod portion 73, which is inserted into the insertion hole 62 at the end of the push rod 6, thereby enabling the push rod 6 to also support the mandrel 7. When the push rod 6 moves, the insertion rod portion 73 can move within the insertion hole 62.

[0052] A ratchet mechanism is also provided between the cylindrical portion 31 and the spindle 7. The ratchet mechanism includes a mounting ring 9 fixedly mounted on the inner wall of the cylindrical portion 31 and a ratchet portion 74 provided on the spindle 7. A spring 91 is provided on the mounting ring 9, and the spring 91 can abut against the wedge-shaped protrusion 741 on the ratchet portion 74. Preferably, four wedge-shaped protrusions 741 are provided on the ratchet portion 74, and the four wedge-shaped protrusions 741 are evenly distributed in the circumferential direction. Therefore, when the lever 3 rotates 90°, it can be blocked by a wedge-shaped protrusion 741. When the guide block 90 moves to any of the endpoints, the spring 91 just cooperates with the wedge-shaped protrusion 741 to restrict the lever 3 from reversing. When the guide block 90 is not at any endpoint position, this structure allows the lever 3 to reverse. For example, if a user presses the lever 3 to make it rotate, and the user releases the lever 3 before the rotation angle reaches 90°, the lever 3 will reverse to the initial position under the action of the return spring 8 because the guide block 90 has not yet moved to the end position of the guide groove 52. However, when the user continues to press the lever 3 to make it rotate 90°, the guide block 90 moves to the end position, and the spring 91 presses against a wedge-shaped protrusion 741, thereby preventing the lever 3 from reversing, and the lever 3 can only continue to rotate forward.

[0053] like Figure 15 , 16 As shown in the figure, for ease of illustration, only the side of the paddle 32 where the paddle is pressed is shown. In the initial position, the guide block 90 is located within one end point, and the reciprocating cylinder 5 is in the zero-stroke position. Figure 17 , 18 As shown, when the paddle part 32 rotates 90°, the guide block 90 moves along the guide groove 52 to the next end point, and the reciprocating cylinder 5 is at the maximum stroke position. At this time, the push rod 6 touches the tactile switch 12, and under the action of the return spring 8, the push rod 6 and the reciprocating cylinder 5 begin to return to their original position. Figure 19 , 20 As shown, under the action of the return spring 8, the movement of the reciprocating cylinder 5 drives the guide block 90 to move in the guide groove 52, thereby driving the paddle part 32 to continue to rotate 90° until the reciprocating cylinder 5 returns to the initial position.

[0054] The spraying device 4 is used to spray disinfectant into the lever portion 32 that rotates to the inside of the housing 11. The spraying device 4 includes a mounting base 41 and an inlet pipe 42 connected to the mounting base 41. A nozzle 411 is provided on the mounting base 41, and the inlet pipe 42 is used to connect to an external liquid storage device.

[0055] like Figure 21 As shown, in this embodiment, preferably, the initial position of the dial 3 is tilted to facilitate pressing by the user. Figure 22As shown, the dial 3 was pressed and rotated 90° by the user. Figure 23 As shown, when the toggle 3 rotates 90°, it triggers the tactile switch 12, thereby controlling the elevator through the control unit. At this time, the toggle 3 continues to rotate under the action of the return spring 8. Simultaneously, the elevator control unit controls the spray device 4 to start spraying to disinfect the toggle section 32 that has entered the housing 11. Figure 24 As shown, the rotation continues until the lever 3 completes its rotation.

[0056] The present invention also provides an epidemic prevention elevator, including an elevator car and an elevator control panel as described above.

[0057] Using the above technical solution, the elevator triggering unit, elevator control panel, and epidemic prevention elevator of the present invention, when in use, press one side of the lever 32 of the lever 3 to rotate the lever 3. The rotation of the lever 3 can drive the reciprocating cylinder 5 and the top rod 6 to move linearly, thereby pressing the tactile switch 12 to trigger the elevator control unit to control the elevator. When the reciprocating cylinder 5 and the top rod 6 return to their original position, they can drive the lever 3 to continue rotating, thereby causing the lever 32 that was just pressed to rotate to the inside of the housing 11. At this time, the elevator control unit can control the spray device 4 to spray disinfectant into the lever 32 that has entered the inside of the housing 11. At the same time, the other lever 32 rotates out from the inside of the housing 11, waiting to be pressed again. Compared with the existing technology's structure that automatically disinfects the buttons of the elevator control panel during use, the elevator triggering unit, elevator control panel, and epidemic prevention elevator of the present invention are simpler, have better stability, and the production and processing of parts and the assembly of the overall structure are very convenient.

[0058] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
