[0002] In modern life, with the increasing demand for food safety and freshness, food preservation refrigeration boxes have become an indispensable electrical appliance in households and commercial kitchens. It not only effectively prolongs the preservation period of food, but also maintains the nutritional ingredients and taste of food, providing us with healthier and more delicious food choices.
[0003] Food is easily contaminated by bacteria, mold and other microorganisms during storage. These microorganisms not only accelerate the spoilage of food, but also may produce harmful substances. At this time, after the food is placed inside the preservation refrigeration box, the stored food needs to be irradiated by the ultraviolet sterilization lamp inside the preservation refrigeration box to achieve effective sterilization. The ultraviolet sterilization lamp mainly uses UVC band (200-280nm) ultraviolet light for sterilization. When microorganisms are exposed to UVC ultraviolet light, their DNA or RNA structure will be damaged, causing cells to be unable to replicate and divide normally, and eventually die.
[0004] Because meat will come into contact with the surface of the ultraviolet sterilization lamp when placed inside the preservation refrigeration box, an oil film will be formed on the surface of the ultraviolet sterilization lamp after the ultraviolet sterilization lamp comes into contact with the meat. The oil film attached to the surface will affect the ultraviolet irradiation intensity of the ultraviolet sterilization lamp, thereby reducing the sterilization effect. Because the ultraviolet sterilization lamp needs to be placed in multiple groups side by side, it is difficult to clean the gaps between the ultraviolet sterilization lamps manually.

DETAILED DESCRIPTION
[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
[0027] The following will be combined with the drawings in the embodiments of the present application to describe the technical solutions in the embodiments of the present application. Figures 1-4 The embodiments of the present application will be further described in detail.
[0028] Embodiment 1
[0029] Please refer to Figures 1-4 The embodiment provides a technical scheme: a food fresh-keeping refrigeration box with a sterilization function, comprising: a fresh-keeping box body 1, an ultraviolet sterilization lamp 2, a scraping and cleaning mechanism 3 and a positioning mechanism 4.
[0030] The sterilization refrigeration box body is composed of the fresh-keeping box body 1 and the ultraviolet sterilization lamp 2 arranged at the two ends of the inner wall. The fresh-keeping box body 1 can set a suitable temperature according to the characteristics of different foods, so that the foods can be stored in the best state. The ultraviolet sterilization lamp 2 mainly uses ultraviolet rays in the UVC band of 200-280 nm for sterilization. When microorganisms are exposed to UVC ultraviolet rays, the DNA or RNA structure will be damaged, resulting in the inability of cells to normally replicate and divide, and eventually death. The above is the prior art, and the following will not be repeated.
[0031] The scraping and cleaning mechanism 3 is arranged outside the ultraviolet sterilization lamp 2. The scraping and cleaning mechanism 3 comprises a first guide rod 301 arranged on the inner wall of the fresh-keeping box body 1 below the ultraviolet sterilization lamp 2, a cleaning block 302 horizontally and slidingly connected to the first guide rod 301, two groups of the cleaning block 302, the ultraviolet sterilization lamp 2 penetratingly arranged in the interior of the cleaning block 302, a fixed seat 303 arranged on the inner wall of the fresh-keeping box body 1 at the bottom of the first guide rod 301 on both sides, two groups of the fixed seat 303, a pulley 304 rotatably connected to the interior of the fixed seat 303, a steel wire rope 305 welded to one end of the outer wall of the cleaning block 302 and a large spring 306 welded to the other end of the two groups of the steel wire rope 305, the steel wire rope 305 penetratingly arranged in the cavity formed by the fixed seat 303 and the pulley 304, and the positioning mechanism 4 arranged on the inner wall of the fresh-keeping box body 1 above the ultraviolet sterilization lamp 2.
[0032] The meat is placed in the interior of the fresh-keeping box body 1. The fresh-keeping box body 1 sets a suitable temperature to ensure that the meat is stored in the best state. Then the ultraviolet sterilization lamp 2 in the interior of the fresh-keeping box body 1 is started. The ultraviolet sterilization lamp 2 uses ultraviolet rays in the UVC band of 200-280 nm for sterilization. When microorganisms are exposed to UVC ultraviolet rays, the DNA or RNA structure will be damaged, resulting in the inability of cells to normally replicate and divide, and eventually death. Thus, the meat placed in the interior of the fresh-keeping box body 1 is sterilized. When the meat placed in the interior of the fresh-keeping box body 1 contacts the ultraviolet sterilization lamp 2, oil film will be attached to the surface of the ultraviolet sterilization lamp 2. At this time, the surface of the ultraviolet sterilization lamp 2 and the dead angle can be quickly scraped and cleaned through the scraping and cleaning mechanism 3. The scraping and cleaning mechanism 3 can be reset to the original position through the positioning mechanism 4, so as to perform scraping work again subsequently.
[0033] When the positioning mechanism 4 no longer continues to position the cleaning block 302, the large spring 306 is contracted by its own elastic force at this time, which will drive the cleaning block 302 at the other end of the steel wire rope 305 to stably realize horizontal displacement on the first guide rod 301. Because the steel wire rope 305 is sleeved on the pulley 304 in the fixed seat 303, at this time, the large spring 306 is contracted by its own elastic force, which provides power for the horizontal displacement of the cleaning block 302. At this time, the cleaning block 302 sleeved outside the ultraviolet sterilization lamp 2 will scrape off the oil film attached to the surface of the ultraviolet sterilization lamp 2.
[0034] Embodiment 2
[0035] Please refer to Figures 1-4 The embodiment provides a technical scheme: a food fresh-keeping refrigerator with a sterilization function, comprising: a mounting block 401, a second guide rod 402, a clamping block 403, a stabilizing rod 404, and a pushing block 405.
[0036] The positioning mechanism 4 comprises a mounting block 401 arranged on the inner wall of the fresh-keeping box body 1 above the ultraviolet sterilization lamp 2. The mounting block 401 is externally provided with a total of four groups of through holes.
[0037] The second guide rod 402 slides in the through holes at the outer two ends of the mounting block 401, the clamping block 403 is welded on the second guide rod 402, the cross-sectional shape of the clamping block 403 is trapezoidal, the stabilizing rod 404 slides in the through holes at the inner two ends of the mounting block 401, one end of the stabilizing rod 404 is welded on the outer wall of the clamping block 403, and the pushing block 405 is welded on the top of the clamping block 403.
[0038] The pushing block 405 is manually pushed to realize displacement, at this time, the pushing block 405 will drive the connected clamping block 403 to realize synchronous displacement in the process of displacement, at this time, the clamping block 403 is connected with the second guide rod 402 and the stabilizing rod 404 in the mounting block 401, at this time, the small spring outside the second guide rod 402 no longer continues to push the clamping block 403, so that the clamping block 403 no longer continues to position the cleaning block 302.
[0039] The implementation principle of the food fresh-keeping refrigerator with a sterilization function is as follows:
[0040] Firstly, the meat is placed in the inside of the fresh-keeping box body 1, the fresh-keeping box body 1 ensures the meat to be preserved in the best state by setting the appropriate temperature, then the ultraviolet sterilization lamp 2 in the inside of the fresh-keeping box body 1 is started, the ultraviolet sterilization lamp 2 uses the ultraviolet of UVC wave band 200-280nm to carry out the sterilization. When the microorganism is exposed to the UVC ultraviolet, the DNA or RNA structure can be damaged, causes the cell to be unable to normal duplication and division, finally dies, thus achieves the sterilization to the meat placed in the inside of the fresh-keeping box body 1, when the meat is placed in the inside of the fresh-keeping box body 1 and contacts the ultraviolet sterilization lamp 2, will make the surface of the ultraviolet sterilization lamp 2 attach the oil film, at this moment, the surface of the ultraviolet sterilization lamp 2 and the dead angle place can be scraped and cleaned quickly by the scraping and cleaning mechanism 3, the scraping and cleaning mechanism 3 can be reset to the original place by the positioning mechanism 4, so as to carry out the scraping work again subsequently.
[0041] Secondly, the displacement is realized by manually rotating the dial block 405, at this moment, the dial block 405 drives the connected clamping block 403 to realize the displacement synchronously, at this moment, the clamping block 403 is no longer limited to the cleaning block 302 because the second guide rod 402 in the inside of the mounting block 401 is connected with the stabilizing rod 404, at this moment, the small spring outside the second guide rod 402 no longer continues to push the clamping block 403, so that the clamping block 403 no longer continues to limit the cleaning block 302.
[0042] Finally, when the positioning mechanism 4 no longer continues to position the cleaning block 302, at this moment, the large spring 306 is contracted by the elastic force of itself, at this moment, the cleaning block 302 at the other end of the steel wire rope 305 stably realizes the horizontal displacement on the first guide rod 301, because the steel wire rope 305 is sleeved on the pulley 304 in the fixed seat 303, at this moment, the power for the horizontal displacement of the cleaning block 302 is provided in the process that the large spring 306 is contracted by the elastic force of itself, at this moment, the cleaning block 302 sleeved outside the ultraviolet sterilization lamp 2 will scrape the oil film attached to the surface of the ultraviolet sterilization lamp 2.
[0043] It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claims involved.
