Description

Technical Field

[0001] The present application relates to the technical field of food preservation, and more specifically, to a food antibacterial and fresh-keeping spray device. Background Art

[0002] For supermarkets, the freshness of food determines whether people buy the food, especially fruits and vegetables, which have a short shelf life. When the external environment temperature is too high in summer, the shelf life of fruits and vegetables will be greatly shortened, reducing people's desire to buy, and eating unfresh food may also affect human health. The prior art proposes a Chinese patent for a vegetable fresh-keeping rack (patent number CN216906654U), in which vegetables are placed on the fresh-keeping rack. By setting components such as a water tank and a spray humidifier, the vegetables on the fresh-keeping rack are replenished with water, thereby achieving the effect of extending the shelf life of vegetables to a certain extent. The defect of the prior art is that the fresh-keeping process often takes a long time. When spraying on the surface of the vegetables, as the spraying time increases, the atomized water mist is easy to re-condense into water droplets, and the water droplets drip on the bottom of the fresh-keeping rack to form puddles, affecting the cleanliness of the environment.

[0003] The document with the prior art publication number CN 218790291 U provides a food antibacterial and fresh-keeping spray device. The device is provided with a water recovery chamber in a fresh-keeping cabinet body. The atomized water mist is sprayed on the surface of fruits and vegetables. As time goes on, a large amount of water mist condenses into water droplets, slides down from the surface of fruits and vegetables and flows downward, enters the water recovery chamber through the recovery mesh, and filters the recovered water that may be mixed with impurities on the surface of fruits and vegetables through the arrangement of an upper filter layer and a lower filter layer. After filtering, the recovered water falls. Since a flow port is provided at the lower end of the partition, the water in the water recovery chamber and the water storage chamber can circulate with each other, which not only avoids water droplets from falling on the lower end of the fresh-keeping cabinet body to form puddles, but also can recycle the dripping water.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: when the device is in use, since the atomizing nozzle is fixed on the opening side of the fresh-keeping cabinet, when the interior of the fresh-keeping cabinet is deep, the atomizing nozzle will have a poor spray effect on the food at the deep end, thereby causing the problem of uneven spraying.

[0005] In view of this, we propose a food antibacterial and fresh-keeping spray device. Utility Model Content

[0006] 1. Technical issues to be solved

[0007] The purpose of the present application is to provide a food antibacterial and fresh-keeping spray device, which solves the technical problems in the above-mentioned background technology and achieves the technical effect of ensuring that the spray on the food on the placement plate is more uniform.

[0008] 2. Technical solution

[0009] The technical solution of the present application provides a food antibacterial and fresh-keeping spray device, comprising a fresh-keeping cabinet body and a plurality of placement plates fixed in the fresh-keeping cabinet body, the placement plates being inclined toward the open end of the fresh-keeping cabinet body, a water pipe being installed through one side of the placement plates, a water inlet hole being opened on one side of the placement plates, a water recovery tank being fixedly installed at the bottom of the fresh-keeping cabinet body and being connected through the water pipe, a water supply mechanism being connected through one side of the water recovery tank, a plurality of water distribution pipes being flexibly connected through the water supply mechanism, a water distribution pipe being arranged at the upper end of the placement plates, the water distribution pipe being rotatably connected to the fresh-keeping cabinet body, a plurality of atomizing nozzles being connected through the water distribution pipe, and a swinging mechanism for making the water distribution pipe swing back and forth is arranged on the fresh-keeping cabinet body.

[0010] By adopting the above technical scheme, the placement plate is tilted toward the open end of the fresh-keeping cabinet, which is conducive to the guidance of water, and enters the water guide pipe through the water inlet hole of each layer, and then flows back to the water recovery tank through the water guide pipe, and then the water in the water recovery tank is extracted through the water supply mechanism to supply water to the water distribution pipe, and the water is atomized by the atomizing nozzle and sprayed on the surface of the food. The two ends of the water distribution pipe are rotatably connected to the middle area of ​​the fresh-keeping cabinet through bearings, and the multiple water distribution pipes are driven to swing back and forth by the swing mechanism to ensure that the food on each layer of the placement plate is sprayed more evenly.

[0032] Reference Figure 1-Figure 7The inclination of the placement plate 101 toward the open end of the fresh-keeping cabinet 1 is conducive to the guidance of water, and the water enters the water guide pipe 102 through the water inlet hole 1021 of each layer, and then flows back to the water recovery tank 2 through the water guide pipe 102, and then the water in the water recovery tank 2 is extracted through the water supply mechanism 3 to supply water to the water distribution pipe 4, and the water is atomized by the atomizing nozzle 401 and sprayed on the surface of the food. The two ends of the water distribution pipe 4 are rotatably connected to the middle area of ​​the fresh-keeping cabinet 1 through bearings, and the swing mechanism 5 drives the multiple water distribution pipes 4 to swing back and forth to ensure that the food on each layer of the placement plate 101 is sprayed more evenly.

[0033] The swing mechanism 5 includes a servo motor 501 fixed on the fresh-keeping cabinet 1, an incomplete gear 502 coaxially fixed to the output shaft of the servo motor 501, a tooth plate 503 meshing with the incomplete gear 502, a plurality of gears 504 meshing with the tooth plate 503, and a spring 505 fixed between the lower end of the tooth plate 503 and the fresh-keeping cabinet 1, each water distribution pipe 4 is coaxially fixed with a gear 504, and a plurality of guide tubes 103 are fixedly installed on the side wall of the fresh-keeping cabinet 1, and the tooth plate 503 is slidably inserted into the guide tubes 103.

[0034] Reference Figure 1 and Figure 2 and Figure 7 , the tooth plate 503 slides along the guide tube 103 to ensure the stability of sliding. When the servo motor 501 drives the incomplete gear 502 to rotate counterclockwise, when the incomplete gear 502 drives the tooth plate 503 to move downward, and the spring 505 is elastically compressed, the tooth plate 503 drives the gear 504 and the water distribution pipe 4 to rotate counterclockwise, so that the atomizing nozzle 401 swings counterclockwise. When the incomplete gear 502 is separated from the tooth plate 503, under the elastic rebound effect of the spring 505, the tooth plate 503 slides upward, and rubs the gear 504 and the water distribution pipe 4 to rotate clockwise, and then the servo motor 501 drives the rotation of the incomplete gear 502, so that the reciprocating swing of the water distribution pipe 4 can be realized.

[0041] Working principle: water is drawn from the water recovery tank 2 through the water supply pipe 302 by the water pump 301 and then diverted to each water distribution pipe 4 through the hose 303. The servo motor 501 is started to drive the incomplete gear 502 to rotate counterclockwise. The incomplete gear 502 drives the tooth plate 503 to move downward, and the spring 505 is elastically compressed. At the same time, the tooth plate 503 drives the gear 504 and the water distribution pipe 4 to rotate counterclockwise, so that the atomizing nozzle 401 swings counterclockwise.
