[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1

[0029] See also Figure 1-7 As shown, a vegetable fresh-keeping door for easy observation includes a door body 1, an observation window 3 is provided on the door body 1, and the observation window 3 is made of a transparent material for observing the internal situation of the fresh-keeping warehouse;

[0030] The observation window 3 is rotatably connected to the door body 1 through a hinge, and a lock is provided on the observation window 3;

[0031] The servo motor 6 is fixedly mounted on the door body 1. The surface of the door body 1 is rotatably connected to a screw 5, and the screw 5 is driven by the servo motor 6.

[0032] The surface of the screw 5 is connected to the bracket 7 through a threaded connection. The surface of the bracket 7 is provided with a cleaning mechanism.

[0033] The cleaning mechanism includes a transverse shaft 4, two screws 5 are provided, a pair of screws 5 are symmetrically arranged with respect to the central axis of the observation window 3, both ends of the transverse shaft 4 are arranged on a bracket 7, and a sponge is provided on the surface of the transverse shaft 4;

[0034] During operation, the transparent observation window 3 can facilitate the staff to observe the internal situation of the fresh-keeping warehouse. At the same time, the openable observation window 3 can facilitate the staff to take and put fruits and vegetables, and the staff does not need to enter the fresh-keeping warehouse to observe the internal situation more intuitively. If steam appears inside or the temperature difference is too large, the observation window 3 will become blurred. At this time, the servo motor 6 is started to drive the screw 5 to rotate forward and reverse. At this time, the thread on the surface of the screw 5 will drive the bracket 7 to move up and down, and the horizontal axis 4 is driven up and down by the bracket 7 to clean the surface of the observation window 3, which is convenient for the staff to observe. By observing the internal situation of the fresh-keeping warehouse through the observation window 3, there is no need to frequently open the warehouse door, and there will be no problem of internal cold air leaking out and reduced insulation effect due to frequent opening and closing of the warehouse door.

[0035] Both ends of the horizontal axis 4 are rotatably connected to the bracket 7 through bearings. The cross section of the sponge is polygonal. A protective cover 2 is provided on the bracket 7. A toggle mechanism is provided on the protective cover 2. The toggle mechanism includes a sliding shaft 10. The sliding shaft 10 is slidably connected to the protective cover 2 through a spring. A notch 12 is provided on the surface of the sliding shaft 10. A block 11 is rotatably connected in the notch 12 through a spring. The surface of the block 11 is an arc surface. A slot 9 is provided on the surface of the horizontal axis 4 relative to the block 11. The block 11 can only rotate in one direction.

[0036] During operation, when the bracket 7 drives the horizontal axis 4 to move, it also drives the protective cover 2 to move. When the protective cover 2 moves to the bottom of the observation window 3, the sliding shaft 10 is squeezed by the bottom surface of the observation window 3, causing the sliding shaft 10 to move upward, and at the same time, it drives the card block 11 to move, so that the card block 11 is stuck in the card slot 9, driving the horizontal axis 4 to rotate, so that the horizontal axis 4 drives the sponge to rotate, so that the other side of the sponge fits the surface of the observation window 3, and then when the servo motor 6 drives the horizontal axis 4 upward again, the clean side of the sponge cleans the observation window 3, ensuring the cleaning effect of the observation window 3. Because the surface of the card block 11 has an arc surface and is rotatable, when the protective cover 2 is away from the ground of the observation window 3, the sliding shaft 10 is reset under the drive of the spring, and then the card block 11 can repeatedly move the horizontal axis 4.

[0037] The surface of the horizontal axis 4 can be slidably connected to the top axis 8 through a spring. A positioning groove is provided on the surface of the protective cover 2 relative to the top axis 8. There are multiple top axis 8, which are evenly distributed. When working, the angle of the horizontal axis 4 can be positioned by cooperating with the positioning groove through the top axis 8 to avoid the sponge rotating by itself when the screw 5 drives the horizontal axis 4 to slide up and down, resulting in random forward and reverse rotation. At the same time, the sponge block can be always attached to the surface of the observation window 3 on one side parallel to the observation window 3, thereby ensuring the cleaning effect of the sponge block.

[0038] Example 2

[0039] See also Figure 8 As shown, in contrast to Example 1, as another embodiment of the present invention, a scraper 13 is fixedly connected to the inner wall of the protective cover 2, and the scraper 13 is arc-shaped and elastic; when working, the scraper 13 can scrape off impurities on the surface of the sponge when the horizontal axis 4 drives the sponge to rotate, thereby improving the sponge cleaning effect after use, and at the same time preventing sand and gravel particles on the sponge from scratching the observation window 3.

[0040] Working principle: through the transparent observation window 3, it is convenient for the staff to observe the internal situation of the fresh-keeping warehouse. At the same time, through the openable observation window 3, it is convenient for the staff to take and put fruits and vegetables, and the staff does not need to enter the fresh-keeping warehouse to observe the internal situation more intuitively. If steam appears inside or the temperature difference is too large, the observation window 3 will be blurred. At this time, the servo motor 6 is started to drive the screw 5 forward and reverse. At this time, the thread on the surface of the screw 5 will drive the bracket 7 to move up and down, and the horizontal axis 4 is driven up and down by the bracket 7 to clean the surface of the observation window 3, which is convenient for the staff to observe. The internal situation of the fresh-keeping warehouse does not need to be frequently opened through the observation window 3, and there will be no problem of internal cold air leakage and reduced insulation effect due to frequent opening and closing of the warehouse door.

[0041] When the bracket 7 drives the horizontal shaft 4 to move, it also drives the protective cover 2 to move. When the protective cover 2 moves to the bottom of the observation window 3, the sliding shaft 10 is squeezed by the bottom surface of the observation window 3, so that the sliding shaft 10 moves upward, and at the same time, it drives the clamping block 11 to move, so that the clamping block 11 is stuck in the clamping groove 9, driving the horizontal shaft 4 to rotate, so that the horizontal shaft 4 drives the sponge to rotate, so that the other side of the sponge is attached to the surface of the observation window 3, and then when the servo motor 6 drives the horizontal shaft 4 to move upward again, the clean side of the sponge cleans the observation window 3, ensuring the cleaning effect of the observation window 3. Because the surface of the clamping block 11 is provided with an arc surface and is rotatable, when the protective cover 2 is away from the ground of the observation window 3, the sliding shaft 10 is reset under the drive of the spring, so that the clamping block 11 can repeatedly toggle the horizontal shaft 4;

[0042] The angle of the horizontal axis 4 can be positioned by cooperating with the positioning groove through the top shaft 8 to prevent the sponge from rotating on its own and randomly reversing when the screw 5 drives the horizontal axis 4 to slide up and down. At the same time, the sponge block can always be attached to the surface of the observation window 3 on one side parallel to the observation window 3, thereby ensuring the cleaning effect of the sponge block. Through the scraper 13, when the horizontal axis 4 drives the sponge to rotate, the scraper 13 can scrape off impurities on the surface of the sponge, thereby improving the cleaning effect of the sponge after use, and preventing sand and gravel particles on the sponge from scratching the observation window 3.
