[0011] When the adjusting member is adjusted, the fine-tuning connecting rod can be driven to move, and the first inclined surface cooperates with the second inclined surface to drive the toggle connecting rod to move, thereby driving the spring sheet to move to adjust the distance between the spring sheet and the contact point.

[0012] Furthermore, it also includes a second elastic member arranged on the base, and the second elastic member is at least used to abut and cooperate with the spring sheet when the spring sheet triggers the contact.

[0013] Furthermore, a mounting groove is provided on the toggle connecting rod, and the fine-tuning connecting rod is arranged in the mounting groove; the adjusting member partially extends into the mounting groove and is connected to the fine-tuning connecting rod.

[0014] Furthermore, it also includes a first elastic member which is sleeved on the adjusting member and located in the mounting groove, one end of the first elastic member abuts against the fine-tuning connecting rod, and the other end of the first elastic member abuts against the inner wall of the mounting groove.

[0015] Furthermore, it also includes a cover plate arranged on the base, and the cover plate partially covers the micro switch.

[0016] Furthermore, the adjusting member is a fine-tuning bolt.

[0017] In addition, the second aspect of the utility model further provides a door body structure, including a door body and the above-mentioned adjustable switch arranged in the door body, and one end of the adjusting member is arranged to pass through the door body.

[0018] In addition, the third aspect of the utility model further provides a disinfection cabinet, comprising a body and the above-mentioned door structure, wherein the door is rotatably arranged on the body, wherein:

[0019] The fuselage is provided with a fixing part which is partially located in the door body, and the fixing part is located at the other end of the base and abuts against the adjusting part;

[0020] When the door is closed, the adjustable switch can be driven to rotate until the door is completely closed, the fixing member abuts against the toggle link and drives the toggle link to rotate, and the toggle link drives the spring to move and contact the contact.

[0021] Furthermore, the fixing member is provided with a limiting protrusion for abutting against the toggle connecting rod.

[0022] Furthermore, the fixing member is provided with a guide groove for abutting against the adjusting member and guiding its rotation.

[0023] Furthermore, a UV lamp group, a controller and a power board are also provided in the fuselage, wherein:

[0024] The micro switch and the power board are both electrically connected to the controller;

[0025] The power board is used to supply power to the UV lamp group, and the micro switch is connected in series in the power supply circuit of the UV lamp group.

[0027] (1) By setting the adjustable switch in the door structure of the disinfection cabinet, the distance between the spring and the contact can be adjusted by adjusting the adjustment member, thereby adjusting the closing stroke of the switch. When the door opening angle is minimized, the switch can be disconnected to stop the UV lamp from working, thereby preventing UV ultraviolet light leakage and ensuring user safety.

[0028] (2) By setting a second elastic member on the base, when the spring sheet triggers the contact, the spring sheet synchronously abuts against the second elastic member; when the door body is opened, the second elastic member releases potential energy and drives the spring sheet to move, making it easier for the spring sheet to drive the toggle connecting rod to rotate, thereby ensuring that the spring sheet is disengaged from the contact to disconnect the switch even when the door opening angle is minimum, thereby ensuring the safety of users.

[0029] (3) By placing the adjustable switch in the door of the disinfection cabinet, the user can avoid accidentally touching the switch, and dust, oil, etc. can be prevented from adhering to the switch and affecting it, thereby ensuring the reliability of the switch. In addition, hiding the adjustable switch in the door also ensures that the appearance of the disinfection cabinet is neat and beautiful.

[0030] (4) When the door is opened, the micro switch is disconnected and the power supply circuit of the UV lamp is directly disconnected, thereby forcibly disconnecting the power supply of the UV lamp, thereby effectively preventing UV ultraviolet light leakage; at the same time, after the micro switch is disconnected, the power board will generate a high-level signal. After the controller detects the high-level signal, it will send a control signal to the power board to disconnect the power supply to the UV lamp, thereby achieving double power-off protection;

[0031] When the door is closed, the micro switch is closed and the power supply circuit of the UV lamp is turned on. At the same time, the power board will generate a low-level signal after the micro switch is closed. After the controller detects the low-level signal, it sends a control signal to the power board to power the UV lamp, thereby lighting the UV lamp. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0043] Embodiment 1

[0044] See also Figure 1-5The utility model provides a disinfection cabinet, including a body 1 and a door 2. A disinfection chamber with a front opening is provided in the body 1. The door 2 is rotatably arranged at the front opening of the body 1 to open or close the disinfection chamber. A UV lamp group (not shown in the figure) is provided in the body 1 and is located in the disinfection chamber. An adjustable switch 3 for controlling the UV lamp group to be turned on or off is provided in the door 2. When the door 2 is opened, the adjustable switch 3 can disconnect the UV lamp group, thereby avoiding UV ultraviolet light leakage and ensuring the safety of the user.

[0045] Specifically, the adjustable switch 3 includes a base 31, a micro switch 32 and a connecting rod assembly. The micro switch 32 is arranged at the upper end of the base 31 and includes a contact 321 and a spring 322 matched with the contact 321. The connecting rod assembly includes a toggle connecting rod 33 rotatably arranged on the base 31, a fine-tuning connecting rod 34 arranged in and matched with the toggle connecting rod 33, and an adjusting member 35 passing through the lower end of the toggle connecting rod 33 and connected to the fine-tuning connecting rod 34. The upper end of the toggle connecting rod 33 abuts against the spring 322. Under the elastic force of the spring 322, the toggle connecting rod 33 can be driven to rotate relative to the base 31, and at this time, the spring 322 and the contact 321 are in a separated state.

[0046] Preferably, the toggle link 33 is provided with a first inclined surface 332, the fine-tuning link 34 is provided with a second inclined surface 341 that abuts against the first inclined surface 332, and the adjusting member 35 is a fine-tuning bolt that is screwed on the fine-tuning link 34. Thus, by screwing the fine-tuning bolt, the fine-tuning link 34 can be driven to move up and down, and the toggle link 33 can be driven to move left and right through the cooperation between the first inclined surface 332 and the second inclined surface 341, thereby driving the spring 322 to move left and right, thereby adjusting the opening and closing stroke of the micro switch 32.

[0047] The spring piece 322 is also provided with a contact block 3221 for contacting the contact point 321 . By providing the contact block 3211 to contact the contact point 321 , the reliability of the contact between the spring piece 322 and the contact point 321 can be further improved.

[0048] In this embodiment, a mounting groove 331 is opened in the toggle connecting rod 33, and the fine-tuning connecting rod 34 is arranged in the mounting groove 331; the upper end of the fine-tuning bolt extends into the mounting groove 331 and is screwed with the bottom of the fine-tuning connecting rod 34, and the lower end of the fine-tuning bolt is arranged to pass through the bottom of the door body 2, so as to facilitate the user to adjust the fine-tuning bolt outside the door body 2.

[0049] It should be noted that during use, the user can adjust the distance between the spring 322 and the contact 321 by adjusting the fine-tuning bolt, thereby adjusting the closing stroke of the switch, and then when the door opening angle is minimum, the switch can be disconnected in time to stop the UV lamp from working, prevent UV ultraviolet light leakage, and ensure user safety.

[0050] Furthermore, the adjustable switch 3 further includes a first elastic member 36 which is sleeved on the fine-tuning bolt and located in the mounting groove 331, one end of the first elastic member 36 abuts against the bottom of the fine-tuning connecting rod 34, and the other end abuts against the inner wall of the mounting groove 331. Thus, under the elastic force of the first elastic member 36, the fine-tuning connecting rod 34 can be driven to abut against the toggle connecting rod 33 all the time, thereby ensuring the close fit between the first inclined surface 332 and the second inclined surface 341.

[0051] Preferably, the first elastic member 36 is a spring.

[0052] In addition, the adjustable switch 3 also includes a cover plate 37 arranged on the base 31, and the cover plate 37 covers the contacts 321 and the spring 322 in the micro switch 32, so as to prevent dust and impurities from adhering to the micro switch 32 and causing the micro switch 32 to fail, thereby ensuring the reliability of the micro switch 32.

[0053] See also Figure 1-2 as well as Figure 5 A hinge 11 for rotationally connecting with the door body 2 is provided below the front end surface of the fuselage 1, and a fixing member 12 is provided on the hinge 11. Part of the fixing member 12 extends into the interior of the door body 2 and is located at the lower end of the base 31, and the fixing member 12 abuts against the adjusting member 35. Therefore, when the door body 2 is in the open state, under the elastic force of the spring 322, the toggle connecting rod 33 can be driven to rotate relative to the base 31, and the adjusting member 35 passing through the toggle connecting rod 33 can be driven to rotate until the adjusting member 35 abuts against the fixing member 12. At this time, the connecting rod assembly is in a balanced state, and the contact 321 is separated from the abutting block 3221 on the spring 322, that is, the micro switch 32 is in the disconnected state.

[0054] Among them, the fixing member 12 is also provided with a limiting protrusion 121 for abutting against the toggle link 33. When the door body 2 is closed, the adjustable switch 3 can be driven to rotate as a whole until the door body 2 is completely closed. At this time, the toggle link 33 abuts against the limiting protrusion 121 on the fixing member 12, and the limiting protrusion 121 drives the toggle link 33 to rotate, thereby driving the spring piece 322 to move and making the abutment block 3221 on the spring piece 322 contact with the contact 321. At this time, the micro switch 32 is closed.

[0055] In this embodiment, the fixing member 12 is a fixing wheel, and a guide groove 122 is provided along its circumferential direction for contacting with the adjusting member 35 and guiding the rotation of the adjusting member 35. By providing the guide groove, the friction force generated when the adjusting member 35 rotates can be reduced, thereby reducing the wear of the fixing wheel and improving the service life of the fixing wheel.

[0056] In addition, a positioning bracket 21 for sleeved on the fixed wheel is further provided in the door body 2, so as to realize rapid positioning of the fixed wheel and improve assembly efficiency.

[0057] Furthermore, a controller and a power board are also provided in the fuselage. The micro switch 32 and the power board are both electrically connected to the controller. The power board is used to supply power to the UV lamp group. The micro switch 32 is connected in series in the power supply circuit of the UV lamp group.

[0058] Therefore, when the door body 2 is opened, the micro switch 32 is disconnected and the power supply circuit of the UV lamp is directly disconnected, thereby forcibly disconnecting the power supply of the UV lamp and effectively preventing UV ultraviolet light leakage; at the same time, after the micro switch 32 is disconnected, the level detection circuit of the power board will generate a high level signal, and the controller will send a control signal to the power board to disconnect the power supply to the UV lamp after detecting the high level signal, thereby achieving double power-off protection;

[0059] When the door body 2 is closed, the micro switch 32 is closed and the power supply circuit of the UV lamp is turned on. At the same time, after the micro switch 32 is closed, the level detection circuit of the power board will generate a low level signal. After detecting the low level signal, the controller sends a control signal to the power board to power the UV lamp, thereby lighting the UV lamp.

[0060] Furthermore, the adjustable switch 3 further comprises a second elastic member 38 disposed on the base 31, preferably, the second elastic member 38 is a spring block; when the abutment block 3221 on the spring sheet 322 abuts against the contact 321, the spring sheet 322 synchronously compresses the spring block and makes the spring block store potential energy. When the door body 2 is opened, the toggle connecting rod 33 is disengaged from the limiting protrusion 121 on the fixing member 12, at which time the spring block releases potential energy and drives the spring sheet 322 to move, and the spring sheet 322 drives the toggle connecting rod 33 to rotate, so that the abutment block 3221 on the spring sheet 322 is disengaged from the contact 321 to disconnect the switch.

[0061] Therefore, by setting the second elastic member 38, the elastic force of the spring piece 322 can be further improved, so that even when the door opening angle is the smallest, the abutment block 3221 on the spring piece 322 can be disengaged from the contact 321 to disconnect the switch, thereby preventing UV light leakage and ensuring user safety.

[0062] In this embodiment, the spring block and the base 31 are integrally formed.

[0063] Embodiment 2

[0064] See also Figure 6 The adjustable switch 3 in this embodiment is different from that in the first embodiment in that the structure of the second elastic member 38 is different. In this embodiment, the second elastic member 38 is a spring, which is arranged on the base 31 and has one end abutting against the spring sheet 322 and the other end abutting against the base 31, that is, the spring abuts against the spring sheet 322 from beginning to end.

[0065] Therefore, by setting a spring, the elastic force of the spring 322 can be increased, making it easier to drive the toggle connecting rod 33 to rotate, thereby ensuring that the abutment block 3221 on the spring 322 is disengaged from the contact 321 to disconnect the switch even when the door opening angle is minimum, thereby preventing UV light leakage and ensuring user safety.

[0066] In summary, the adjustable switch 3, door structure and disinfection cabinet provided by the utility model have the following effects:

[0067] (i) By arranging the adjustable switch 3 in the door structure of the disinfection cabinet, the distance between the spring 322 and the contact 321 can be adjusted when the adjusting member 35 is adjusted, thereby adjusting the closing stroke of the switch, and then the switch can be disconnected to stop the UV lamp when the door opening angle is minimum, thereby preventing UV ultraviolet light leakage and ensuring user safety.

[0068] (ii) By arranging a second elastic member 38 on the base 31, when the spring piece 322 triggers the contact 321, the spring piece 322 synchronously abuts against the second elastic member 38; when the door body 2 is opened, the second elastic member 38 releases potential energy and drives the spring piece 322 to move, so that the spring piece 322 can more easily drive the toggle connecting rod 33 to rotate, thereby ensuring that the spring piece 322 is disengaged from the contact 321 to disconnect the switch even when the door opening angle is minimum, thereby ensuring the safety of users.

[0069] (III) By arranging the adjustable switch 3 in the door body 2 of the disinfection cabinet, it is possible to prevent the user from accidentally touching the switch, and it is also possible to prevent dust, oil, etc. from adhering to the switch and affecting it, thereby ensuring the reliability of the switch. In addition, hiding the adjustable switch 3 in the door body 2 also ensures that the appearance of the disinfection cabinet is neat and beautiful.

[0070] (iv) When the door is opened, the micro switch is disconnected and the power supply circuit of the UV lamp is directly disconnected, thereby forcibly disconnecting the power supply of the UV lamp, thereby effectively preventing UV ultraviolet light leakage; at the same time, after the micro switch is disconnected, the power board will generate a high-level signal. After the controller detects the high-level signal, it will send a control signal to the power board to disconnect the power supply to the UV lamp, thereby achieving double power-off protection;

[0071] When the door is closed, the micro switch is closed and the power supply circuit of the UV lamp is turned on. At the same time, the power board will generate a low-level signal after the micro switch is closed. After the controller detects the low-level signal, it sends a control signal to the power board to power the UV lamp, thereby lighting the UV lamp.

[0072] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0073] It should be understood that the orientations or positional relationships indicated by the terms "top", "bottom", "inside", "outside", etc. are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the modules or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0074] In addition, in the description of the present utility model, "multiple" and "several" mean two or more than two, unless otherwise clearly and specifically defined.
