Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of disinfection equipment, in particular to a disinfection cabinet. BACKGROUND

[0002] The door and the drawer of the traditional disinfection cabinet are fixed together and are pulled out on the guide rail. The door opening mode is straight pulling type. Such straight pulling type structure requires the user to bend over or squat to open the door. That is, the cabinet door cannot be automatically opened, and the degree of automation is low. CONTENT OF THE UTILITY MODEL

[0003] Therefore, it is necessary to provide a disinfection cabinet to solve the problem that the cabinet door of the existing disinfection cabinet cannot be automatically opened.

[0004] The disinfection cabinet provided by the present application comprises a drawer, a cabinet body and a driving part. The driving part comprises a motor, a driving gear, a first driven gear, a second driven gear and a rack. The motor, the driving gear, the first driven gear and the second driven gear are respectively installed in one of the cabinet body and the drawer. The rack is installed in the other one of the cabinet body and the drawer. The driving gear is fixedly connected to the output shaft of the motor. The driving gear and the first driven gear are in meshing connection. The first driven gear and the second driven gear are coaxially arranged and fixedly connected. The second driven gear and the rack are in meshing connection. The rack extends along a preset direction, so that the drawer can extend or retract relative to the cabinet body along the preset direction.

[0005] In one of the embodiments, the driving gear is a sector gear. The sector gear is provided with a meshing tooth edge for meshing connection with the first driven gear. The corresponding central angle A of the meshing tooth edge satisfies 10°≤A≤180°.

[0006] In one of the embodiments, the two ends of the meshing tooth edge are respectively provided with a first limiting protrusion and a second limiting protrusion, so that the meshing transmission range of the meshing tooth edge relative to the first driven gear is limited between the first limiting protrusion and the second limiting protrusion.

[0007] In one of the embodiments, the rotation radius of the first driven gear is smaller than the rotation radius of the second driven gear.

[0008] In one of the embodiments, the rotation radius of the first driven gear is equal to the rotation radius of the second driven gear.

[0009] In one of the embodiments, the driving part further comprises a baffle. The baffle is arranged between the first driven gear and the second driven gear. One end of the baffle close to the first driven gear is limitingly arranged on one side of the driving gear. The other end of the baffle close to the second driven gear is limitingly arranged on one side of the rack.

[0010] In one of the embodiments, the rotation radius of the driving gear is greater than the rotation radius of the first driven gear.

[0011] In one embodiment, the rack has a first stop head and a second stop head at each end, so that the meshing transmission range of the rack relative to the second driven gear is limited between the first stop head and the second stop head.

[0012] In one embodiment, the disinfection cabinet further includes a fixed bracket, which is installed on the cabinet body. The driving gear, the first driven gear, and the second driven gear are rotatably connected to the fixed bracket. The rack is installed on the drawer. The fixed bracket is provided with a limiting hole, through which the rack is movably inserted and meshed with the second driven gear.

[0013] In one embodiment, the disinfection cabinet also includes a controller, and has multiple drawers. Each drawer has at least one corresponding drive unit, and each drive unit is electrically connected to the controller. The controller can control the corresponding drive unit to drive the drawer to extend or retract.

[0014] Compared with the prior art, the disinfection cabinet provided in this application is designed in such a way that users do not need to bend over or squat down to pull out the drawers. Instead, the drawers can be automatically extended or retracted by the motor of the drive unit, which greatly improves the automation level of the disinfection cabinet drawer opening and closing.

[0015] Furthermore, since the drive unit transmits power through a driving gear, a first driven gear, a second driven gear, and a rack, this configuration not only ensures the accuracy of the drive unit's transmission but also allows it to withstand larger loads, enabling the drawer to be pulled out smoothly.

Detailed Implementation

[0020] Traditional disinfection cabinets have doors and drawers that are fixed together and pulled out on guide rails. The door opens in a straight-pull manner, which requires the user to bend over or squat to open it. In other words, the cabinet door cannot open automatically, resulting in a low level of automation.

[0021] To address the issue of existing disinfection cabinet doors not opening automatically, this application provides a disinfection cabinet (including but not limited to disinfection cabinets, refrigerators, and other components). Please refer to [link / reference]. Figure 1 and Figure 2 The disinfection cabinet includes a drawer 100, a cabinet body 200, a drive unit 300, and a track unit 500. The drawer 100 slides and engages with the cabinet body 200 along a preset direction via the track unit 500.

[0022] The drive unit 300 includes a motor 310, a drive gear 320, a first driven gear 330, a second driven gear 340, and a rack 350. The motor 310, drive gear 320, first driven gear 330, and second driven gear 340 are respectively installed in one of the cabinet 200 and the drawer 100. The rack 350 is installed in the other of the cabinet 200 and the drawer 100. The drive gear 320 is connected to the output shaft of the motor 310. The drive gear 320 and the first driven gear 330 are meshed together. The first driven gear 330 and the second driven gear 340 are coaxially arranged and fixedly connected. The second driven gear 340 and the rack 350 are meshed together. The rack 350 extends along a preset direction so that the drawer 100 can extend or retract relative to the cabinet 200 in a preset direction.

[0023] With this design, users do not need to bend over or squat to open the drawer 100. Instead, the drawer 100 can be automatically extended or retracted by the motor 310 of the drive unit 300, which greatly improves the automation level of opening and closing the disinfection cabinet drawer 100.

[0024] Furthermore, since the drive unit 300 transmits power through the driving gear 320, the first driven gear 330, the second driven gear 340, and the rack 350, this configuration not only ensures the accuracy of the drive unit 300's transmission but also allows it to withstand a large load, thus enabling the drawer 100 to be pulled out smoothly.

[0025] In one embodiment, the rotation radius of the first driven gear 330 is smaller than the rotation radius of the second driven gear 340.

[0026] With this configuration, the movement distance of the rack 350 can be increased while the rotation angle of the motor 310 remains unchanged, which greatly improves the transmission efficiency of the drive unit 300.

[0027] In another embodiment, such as Figure 2 As shown, the rotation radius of the first driven gear 330 is equal to the rotation radius of the second driven gear 340.

[0028] This makes the transmission of the drive unit 300 smoother.

[0029] Furthermore, in one embodiment, as Figure 2 As shown, the drive unit 300 also includes a baffle 360, which is disposed between the first driven gear 330 and the second driven gear 340. The end of the baffle 360 ​​near the first driven gear 330 is limited to one side of the drive gear 320, and the end of the baffle 360 ​​near the second driven gear 340 is limited to one side of the rack 350.

[0030] The two ends of the baffle 360 ​​can be welded, glued, or snapped to the first driven gear 330 and the second driven gear 340 respectively. However, it should be noted that the first driven gear 330 and the second driven gear 340 can also be fixedly connected by a rotating shaft.

[0031] Obviously, when the rotation radius of the first driven gear 330 is equal to the rotation radius of the second driven gear 340, the driving gear 320 and the rack 350 are prone to misalignment. Therefore, this arrangement can prevent the rack 350 from moving to the first driven gear 330 and prevent the driving gear 320 from moving to the second driven gear 340, that is, prevent the driving gear 320 and the rack 350 from misalignment.

[0032] In another embodiment, the rotation radius of the first driven gear 330 is greater than the rotation radius of the second driven gear 340.

[0033] With this configuration, the first driven gear 330 and the second driven gear 340 can act as speed reducers, reducing the moving speed of the rack 350.

[0034] In one embodiment, such as Figure 2 As shown, the rotation radius of the driving gear 320 is greater than that of the first driven gear 330.

[0035] With this configuration, the rotation angle of the first driven gear 330 and the second driven gear 340 can be increased while the rotation angle of the motor 310 remains unchanged. This increases the travel distance of the rack 350, which in turn helps to improve the transmission efficiency of the drive unit 300.

[0036] However, this is not the only one. In other embodiments, the rotation radius of the driving gear 320 may be less than or equal to the rotation radius of the first driven gear 330.

[0037] In one embodiment, such as Figure 2 As shown, the driving gear 320 is a sector gear, which has a meshing tooth edge 321 for meshing with the first driven gear 330. The central angle A corresponding to the meshing tooth edge 321 of the sector gear satisfies 10°≤A≤180°.

[0038] The sector gear has a compact structure, which can reduce the overall size of the drive gear 320. Therefore, this design is beneficial for the drive gear 320 to adapt to working conditions with limited installation space.

[0039] Furthermore, in one embodiment, as Figure 2 As shown, the two ends of the meshing tooth edge 321 are respectively provided with a first limiting protrusion 322 and a second limiting protrusion 323, so that the meshing transmission range of the meshing tooth edge 321 relative to the first driven gear 330 is limited between the first limiting protrusion 322 and the second limiting protrusion 323.

[0040] In other words, when the meshing tooth edge 321 rotates to the point where the first limiting protrusion 322 contacts the first driven gear 330, the driving gear 320 cannot continue to rotate. Similarly, when the meshing tooth edge 321 rotates to the point where the second limiting protrusion 323 contacts the first driven gear 330, the driving gear 320 also cannot continue to rotate. This design prevents the driving gear 320 from rotating excessively, which could cause the meshing tooth edge 321 and the first driven gear 330 to disengage.

[0041] However, this is not the only one. In other embodiments, the rotation angle of the motor 310 can also be set to prevent the meshing edge 321 of the driving gear 320 and the first driven gear 330 from disengaging.

[0042] In one embodiment, such as Figure 2 As shown, the rack 350 has a first stop head 351 and a second stop head (not shown) at both ends, so that the meshing transmission range of the rack 350 relative to the second driven gear 340 is limited between the first stop head 351 and the second stop head.

[0043] It should be noted that the first stop head 351 and the second stop head can be detachably installed at both ends of the rack 350 to facilitate the assembly of the rack 350.

[0044] In other words, when the rack 350 moves to the point where it contacts the first stop head 351 and the second driven gear 340, the rack 350 cannot continue to move; similarly, when the rack 350 moves to the point where it contacts the second stop head and the second driven gear 340, the rack 350 cannot continue to move. This design prevents the rack 350 from moving excessively, which could cause the rack 350 and the second driven gear 340 to disengage.

[0045] In one embodiment, such as Figure 2 As shown, the disinfection cabinet also includes a fixed bracket 400, which is installed on the cabinet body 200. The driving gear 320, the first driven gear 330 and the second driven gear 340 are rotatably connected to the fixed bracket 400. The rack 350 is installed on the drawer 100. The fixed bracket 400 is provided with a limiting hole 411. The rack 350 is movably inserted through the limiting hole 411 and meshes with the second driven gear 340.

[0046] Specifically, the fixed bracket 400 includes a base 410, a first connecting part 420 and a second connecting part 430. The first connecting part 420 and the second connecting part 430 are spaced apart along a preset direction and are respectively connected to the base 410. A limiting hole 411 is provided in the base 410. The output shaft of the motor 310 is rotatably passed through the first connecting part 420 and fixedly connected to the drive gear 320. The second connecting part 430 is provided with a mounting groove 431. The first driven gear 330 and the second driven gear 340 are mounted in the mounting groove 431 through a rotating shaft, and the inner walls on both sides of the mounting groove 431 limit the first driven gear 330 and the second driven gear 340.

[0047] This design has two advantages. First, by setting the fixed bracket 400, the assembly difficulty of the drive unit 300 between the cabinet 200 and the drawer 100 can be reduced. Second, by setting the limiting hole 411 in the fixed bracket 400, the rack 350 can be prevented from shifting and getting stuck, thus improving the smoothness of the drawer 100's pulling out.

[0048] Furthermore, in one embodiment, the cross-section of the limiting hole 411 and the cross-section of the rack 350 are both convex, and the rack 350 can be movably engaged with the limiting hole 411.

[0049] In one embodiment, the disinfection cabinet also includes a controller (not shown), and there are multiple drawers 100. Each drawer 100 is provided with at least one drive unit 300. Each drive unit 300 is electrically connected to the controller, and the controller can control the corresponding drive unit 300 to drive the drawer 100 to extend or retract.

[0050] This setup allows for automatic control of multiple drawers 100, greatly improving the control efficiency of the disinfection cabinet.
