Technical Field

[0001] The utility model relates to the technical field of instrument disinfection, in particular to an auxiliary disinfection device. Background Art

[0002] The main technological steps of plant seedling raising are as follows:

[0003] 1. Obtain parts of tissues from various plants, mainly precious plants;

[0004] 2. Establish a sterile breeding system as the culture environment for plant tissues;

[0005] 3. Realize the proliferation of seedlings in a sterile environment and promote the growth of strong seedlings;

[0006] 4. Carry out rooting culture on the seedlings with strong seedling growth to obtain healthy plant roots;

[0007] 5. Plant the plant roots on the soil in the greenhouse for hardening off;

Detailed implementation mode

[0033] The embodiments of the technical solutions of the present utility model will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to illustrate the technical solutions of the present utility model more clearly, so they are only examples and cannot be used to limit the protection scope of the present utility model.

[0034] Please refer to Figures 1 to 3 , the present utility model provides an auxiliary disinfection device, which is arranged in the vacuum steam sterilization body 1 and includes a support cylinder 100, a placing board 200, a placing frame 300 and a circumferential rotation drive structure 400.

[0035] Specifically, the support cylinder 100 is rotatably and vertically arranged in the vacuum steam sterilization body 1. There are multiple placing boards 200, and the multiple placing boards 200 are circumferentially spaced on the support cylinder 100 through connecting rods. A placing frame 300 with an openable top cover is fixed on each placing board 200. A plurality of air vents communicating with its inner cavity are opened on the placing frame 300, and the items to be disinfected can be placed in the placing frame 300; the circumferential rotation drive structure 400 is connected to the support cylinder 100 and can drive the support cylinder 100 to rotate around its main axis.

[0036] During use, place the solid items to be disinfected, such as tools, utensils, culture media, etc., individually in the placing frame 300, then close and fix the top cover of the placing frame 300, and then close the vacuum steam sterilization body 1 and start the circumferential rotation drive structure 400 and the vacuum steam sterilization body 1, then the disinfection work can be carried out.

[0037] With the above-mentioned auxiliary disinfection device, during the disinfection process, the solid tools, utensils, culture media, etc. are separated individually, which can prevent the items from piling up together and causing uneven disinfection and mutual collision between the items. In addition, during the disinfection process, by rotating, the position of the object in the vacuum steam sterilization body 1 is continuously changed, further improving the disinfection effect.

[0038] As a preferred implementation mode, the device further includes a self-rotation drive structure 500. The connecting rod is rotatably connected to the support cylinder 100. The self-rotation drive structure 500 is connected to all the connecting rods and can sequentially drive all the connecting rods to rotate 180° around their own main axes.

[0039] When in use, by continuously turning the objects 180°, uneven disinfection of the bottom and top of the objects can be avoided.

[0040] Specifically, the self-rotation drive structure 500 includes a cylindrical inner sleeve 510, a connecting plate 520 and a driving rod 53. The inner sleeve 510 is inserted and fixed outside the support tube 100, and a V-shaped notch 511 is provided on the top of the inner sleeve 510. The end of the connecting rod extending into the support tube 100 is provided with a connecting plate 520, and two driving rods 530 are arranged on each connecting plate 520 in a horizontally opposite manner, and the two driving rods 530 on the same connecting plate 520 are simultaneously tightly attached to the top surface of the inner sleeve 510 and can slide along the top surface of the inner sleeve 510.

[0041] When in use, when the support tube 100 rotates, it can drive all the connecting rods to rotate, and at the same time drive all the driving rods 530 to slide against the top surface of the inner sleeve 510. When the front driving rod 530 slides to the V-shaped notch 511, under the action of gravity, the front end of the connecting plate 520 rotates downward, and the front driving rod 530 slides against the surface of the V-shaped notch 511. At this time, the connecting rod slowly rotates and drives the rear driving rod 530 to rotate upward until the front driving rod 530 moves to the top of the V-shaped notch 511. At this time, the connecting plate 520 rotates 90°, and the storage plate 200 is in a vertical state.

[0042] As the support tube 100 continues to rotate and under the action of inertia, the connecting plate 520 continues to flip until the rear driving rod 530 overlaps the top of the inner sleeve 510. As the support tube 100 continues to rotate, the connecting rod is driven to continue to rotate, and then the storage plate 200 is driven to continue to rotate. Then the support tube 100 continues to rotate, and the lower driving rod 530 continues to move up and down along the other side of the V-shaped notch 511 until it finally disengages from the V-shaped notch 511. At this time, the upper driving rod 530 gradually rotates from the 90° position to the 180° direction. After the driving rod 530 disengages from the V-shaped notch 511, the two driving rods 530 continue to move against the top surface of the inner sleeve 510 again.

[0043] In this way, multiple storage frames 300 can be easily driven to flip, so as to achieve the purpose of disinfecting fixed items individually, in a changed position, and in a changed state.

[0044] As a preferred embodiment, the auxiliary flipping assembly 540 includes a support rod 541, a cantilever 542, and a guide rod 543. A rectangular sinking groove 512 is provided at the bottom of the V-shaped notch 511. The width of the sinking groove 512 is greater than the rod diameter of the driving rod 530. During the rotation of the support cylinder 100, the driving rod 530 can fall into the sinking groove 512 along the V-shaped notch 511. The support rod 541 is located inside the inner sleeve. The cantilever 542 is arranged on the support rod 541 and extends horizontally and laterally outward. The guide rod 543 is arranged at the end of the cantilever 542 and is located directly above the sinking groove 512. The top end of the guide rod 543 is provided with an arc-shaped guiding surface, and the arc-shaped guiding surface is axisymmetric with respect to the center of the sinking groove 512. When one of the driving rods 530 on the same connecting plate 520 falls into the sinking groove 512 along the V-shaped notch 511, the other driving rod 530 can slide along the arc-shaped guiding surface.

[0045] During use, after the lower driving rod 530 slides along the surface of the V-shaped notch 511 into the sinking groove 512 and falls into the sinking groove 512, the upper driving rod 530 can rotate forward around the front driving rod 530 and then overlap on the top of the inner sleeve 510. At this time, after the self-rotation driving structure 500 completes a 180° flip, it can continue to move forward. Through the sinking groove 512, it is possible to ensure that the self-rotation driving structure 500 can complete a 180° flip.

[0046] In this embodiment, the circumferential rotation driving structure 400 includes a rotation power source 410, a driving gear 420, and a driven gear 430. The support cylinder is rotatably arranged at the bottom of the vacuum steam sterilization body 1. The rotation power source 410 is arranged inside the vacuum steam sterilization body 1. The driving gear 420 is arranged on the rotation shaft of the rotation power source 410. The driven gear 430 is sleeved and fixed on the support cylinder and meshes with the driving gear 420.

[0047] When the rotation power source 410 is started, the support cylinder 100 can be driven to rotate. Of course, in other embodiments, the circumferential rotation driving structure 400 can also be in other structural forms, such as directly driving the support cylinder 100 to rotate by a rotating motor, or adopting a belt pulley driving method.

[0048] The usage method of the above auxiliary disinfection device:

[0049] During use, place the solid items to be disinfected, such as tools, utensils, culture media, etc., individually in the storage frame 300. Then close and fix the top cover of the storage frame 300. Next, close the vacuum steam sterilization body 1 and start the circumferential rotation driving structure 400 and the vacuum steam sterilization body 1, and then the disinfection work can be carried out.

[0050] With the above-mentioned auxiliary disinfection device, during the disinfection process, solid tools, utensils, culture media, etc. are separated to prevent items from piling up together, which may cause uneven disinfection and mutual collision between items. In addition, during the disinfection process, the position of the object in the vacuum steam sterilization body 1 is continuously changed by rotation to further improve the disinfection effect.

[0051] In addition, through the self-rotation drive structure 500, it is convenient to drive multiple storage frames 300 to perform multiple 180° flips, so as to achieve the purpose of disinfecting fixed items separately with changing positions and states, and further improve the disinfection effect.

[0052] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
