A disc is located at the top of the rotating shaft, and a rim is provided on the outer side of the top of the disc. Connecting cylinders are located on the left and right sides of the bottom of the disc, and ball bearings are located at the bottom of the connecting cylinders. A circular groove is formed on the bottom surface of the inner wall of the sterilization chamber, perpendicular to the ball bearings, allowing the ball bearings to roll and connect with the circular groove. A control box is located on the right side inside the sterilization chamber. A PLC controller is located on the upper part of the inner wall of the control box, and a voltage regulator is located on the inner wall surface of the control box below the PLC controller. This utility model has the advantages of good food sterilization effect, uniform food sterilization, high degree of automation, and convenient operation.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can ensure uniform sterilization of food to a certain extent, it still has some problems. When food is placed closely together, the sterilization of the food and the contact surfaces with the ultraviolet disinfection lamp and microwave generator is uneven compared to the exposed surfaces. To solve this problem, the food needs to be repeatedly turned over manually, which increases the workload and is inconvenient. Therefore, in order to address the above problems, we propose a food sterilization device. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide a food sterilization device that reduces sterilization dead spots on food, ensures sterilization uniformity, and reduces manual operation steps during food sterilization.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a food sterilization device, comprising a sterilization chamber with a hinged door, a sterilization assembly inside the sterilization chamber, a cavity at the bottom of the sterilization chamber, a motor inside the cavity, a rotating rod connected to the output end of the motor, one end of the rotating rod extending into the interior of the sterilization chamber and rotatably connected to the sterilization chamber, a perforated plate detachably connected to the top of the rotating rod via a connector, a fixed cylinder on the inner bottom surface of the sterilization chamber, the rotating rod rotatably connected to the interior of the fixed cylinder, a flipping assembly on the fixed cylinder, the flipping assembly comprising an air pump located inside the cavity, a hose connected to the output end of the air pump, an air jet pipe connected to the hose, and multiple air jet heads equidistantly arranged along the length extension direction of the air jet pipe, the air jet pipe being connected to the fixed cylinder.

[0007] The beneficial effects of this utility model are as follows: by setting up a flipping component, when the motor drives the perforated plate to rotate, the sterilization component will sterilize the food on the perforated plate. At the same time, the air pump sprays gas through the hose from the jet component, blowing the food on the perforated plate over, thereby turning the food over and sterilizing the food more evenly.

[0008] To reduce the amount of debris falling from the perforated plate and clogging the air vents;

[0009] As a further improvement to the above technical solution: the output end of the jet head is round, and the output end of the jet head has multiple jet holes.

[0010] The beneficial effects of this improvement are: during use, the round-headed jet nozzle can reduce the retention of debris on the jet nozzle, and the multiple jet holes can prevent large local impact forces from blowing food away from the perforated plate.

[0011] To facilitate the removal of the perforated disc;

[0012] As a further improvement to the above technical solution: the connector includes a square block connected to the bottom of the hollowed-out disc and a square groove opened on the rotating rod, the square groove being adapted to the square block.

[0013] The beneficial effects of this improvement are: before and after food sterilization, it is convenient to remove the perforated plate and spread the food evenly on the perforated plate or remove the food, thus facilitating operation. When the perforated plate is in the sterilization chamber, the square block is inserted into the square groove, and the perforated plate can be rotated when the rotating rod is rotated.

[0014] To ensure even sterilization of food;

[0015] As a further improvement to the above technical solution: the sterilization component includes an ultraviolet disinfection lamp installed on at least one inner wall of the sterilization chamber and a microwave generator installed on the top and bottom surfaces of the sterilization chamber.

[0016] The beneficial effects of this improvement are as follows: by installing ultraviolet disinfection lamps on at least one inner wall, when the rotating rod drives the perforated plate to rotate, the food on the perforated plate can all come into contact with the perforated plate. At the same time, microwave generators are symmetrically arranged on the inner top and inner bottom surfaces of the sterilization chamber, which can sterilize the top and bottom surfaces of the food simultaneously, increasing the efficiency and uniformity of sterilization.

[0017] To facilitate adjustment of the jet head angle according to sterilization requirements;

[0018] As a further improvement to the above technical solution: a damping shaft is rotatably connected between the fixed cylinder and the inner wall of the sterilization chamber, and the air jet pipe is located on the damping shaft.

[0019] The beneficial effects of this improvement are: when it is necessary to adjust the angle of the jet head, the jet pipe can be rotated to drive the damping shaft to rotate to a certain angle for fixing, so that the jet head can be used for various needs.

[0020] To increase the balance of the openwork plate;

[0021] As a further improvement to the above technical solution: the sterilization chamber is provided with an auxiliary frame for supporting the hollowed-out disc, and multiple ball bearings are rotatably connected to the auxiliary frame.

[0022] The beneficial effects of this improvement are as follows: when the hollow disk is connected to the rotating rod, the outer edge of the hollow disk contacts the auxiliary frame, providing auxiliary support for the hollow disk. At the same time, the multiple rolling balls can reduce friction when the hollow disk rotates, making the hollow disk rotate more smoothly.

[0023] To ensure ventilation inside the sterilization chamber;

[0024] As a further improvement to the above technical solution: multiple ventilation holes are symmetrically opened on the inner walls of both sides of the sterilization chamber.

[0025] The beneficial effects of this improvement are: by symmetrically opening multiple ventilation holes on both sides, the air inside the sterilization chamber can be circulated, and the internal temperature can be effectively reduced to prevent the temperature from rising continuously.

[0033] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0034] like Figure 1-6 As shown, a food sterilization device includes a sterilization chamber 1 with a door 2 hinged to it. A sterilization assembly is located inside the sterilization chamber 1. A cavity 4 is formed at the bottom of the sterilization chamber 1, and a motor 5 is installed inside the cavity 4. A rotating rod 6 is connected to the output end of the motor 5. One end of the rotating rod 6 extends into the interior of the sterilization chamber 1 and is rotatably connected to it. A perforated plate 8 is detachably connected to the top of the rotating rod 6 via a connector. In use, food such as cheese, soy products, and nuts are evenly spread on the perforated plate 8. Then, the perforated plate 8 is connected to the rotating rod 6 via the connector. The door 2 is then closed. The motor 5 drives the rotating rod 6 to rotate, simultaneously rotating the perforated plate 8. The rotating perforated plate 8 evenly contacts the sterilization assembly at every point, effectively sterilizing the food. The perforated design of the perforated plate 8 also improves the uniformity of food sterilization.

[0035] A fixed cylinder 9 is provided on the inner bottom surface of the sterilization chamber 1. The rotating rod 6 is rotatably connected to the inside of the fixed cylinder 9, which also increases the stability of the rotating rod 6. The fixed cylinder 9 is provided with a flipping assembly, which includes an air pump 101 located inside the cavity 4, a hose 102 connected to the output end of the air pump 101, an air jet pipe 103 connected to the hose 102, and multiple air jets 104 equidistantly arranged along the length of the air jet pipe 103. The air jet pipe 103 is connected to the fixed cylinder 9. During use, when the rotating rod 6 drives the hollow plate 8 to rotate, the air pump 101 pumps gas through the hose 102. The gas enters the air pipe 103 and then exits from the air nozzle 104. The length of the air pipe 103 can be the same as the radius of the perforated plate 8. Multiple air nozzles 104 are also evenly distributed on the air pipe 103. When the perforated plate 8 rotates, the gas sprayed by the air nozzles 104 just covers the radius area of ​​the perforated plate 8, thereby evenly blowing the food on the perforated plate 8. Before use, the blowing volume of the air pump 101 can be controlled to avoid blowing the food away from the perforated plate 8 due to excessive blowing force. During the continuous turning of the food, the contact area with the sterilization components can be increased, improving the uniformity of sterilization.

[0036] Furthermore, the output end of the jet head 104 is round, and the output end of the jet head 104 is provided with multiple jet holes 11. During use, some food on the hollow plate 8 may fall off. The round shape of the jet head 104 can reduce the amount of food that stays on the jet head 104 and reduce the risk of the jet head 104 becoming clogged. At the same time, the multiple jet holes 11 can prevent large local impact forces from blowing the food away from the hollow plate 8.

[0037] Furthermore, the connector includes a square block 71 connected to the bottom of the perforated tray 8 and a square groove 72 formed on the rotating rod 6. The square groove 72 is adapted to the square block 71. When the perforated tray 8 needs to be placed inside the sterilization chamber 1, the square block 71 at the bottom of the perforated tray 8 is locked in the square groove 72 on the rotating rod 6. When the rotating rod 6 rotates, it can drive the perforated tray 8 to rotate. At the same time, after sterilization, the perforated tray 8 can be easily disassembled to facilitate the removal of the sterilized food.

[0038] Furthermore, the sterilization assembly includes an ultraviolet disinfection lamp 31 installed on at least one inner wall of the sterilization chamber 1 and a microwave generator 32 installed on the top and bottom surfaces of the sterilization chamber 1. In use, the ultraviolet disinfection lamp 31 is installed on at least one inner wall. When the rotating rod 6 drives the perforated plate 8 to rotate, the food on the perforated plate 8 can be evenly contacted by the ultraviolet disinfection lamp 31. In addition, the microwave generator 32 on the top and bottom surfaces of the sterilization chamber 1 can evenly disinfect the upper and lower surfaces of the food, thereby improving the uniformity of sterilization and the efficiency of sterilization.

[0039] Furthermore, a damping shaft 12 is rotatably connected between the fixed cylinder 9 and the inner wall of the sterilization chamber 1. The air jet pipe 103 is located on the damping shaft 12. When it is necessary to adjust the angle of the air jet head 104 during use, the air jet pipe 103 can be rotated to drive the damping shaft 12 to rotate to a certain angle for fixing, so that the air jet head 104 can be adapted to various needs.

[0040] Furthermore, the sterilization chamber 1 is equipped with an auxiliary frame 13 for supporting the hollowed-out plate 8. Multiple balls 14 are rolled on the auxiliary frame 13. When the hollowed-out plate 8 is connected to the rotating rod 6, the outer edge of the hollowed-out plate 8 contacts the auxiliary frame 13 to provide auxiliary support for the hollowed-out plate 8. At the same time, the multiple rolling balls 14 can reduce friction when the hollowed-out plate 8 rotates, so that the hollowed-out plate 8 can rotate more smoothly.

[0041] Furthermore, multiple ventilation holes 15 are symmetrically opened on the inner walls of both sides of the sterilization chamber 1. During use, the air inside the sterilization chamber 1 can be circulated through the multiple ventilation holes 15 symmetrically opened on both sides, which can also effectively reduce the internal temperature and prevent the temperature from rising continuously.

[0042] The working principle and usage process of this utility model are as follows: When using this equipment, first, the food to be sterilized is evenly spread on the perforated tray 8, and then the perforated tray 8 is placed in the sterilization chamber 1. The square block 71 is inserted into the square groove 72, and the outer edge of the perforated tray 8 contacts the auxiliary frame 13. The air jet pipe 103 is rotated to adjust the air jet head 104 to a suitable angle. Then, the chamber door 2 is closed, the ultraviolet disinfection lamp 31 and the microwave generator 32 are turned on, and the motor 5 and the air pump 101 are started. Then, the motor 5 drives the rotating rod 6 and the perforated tray 8 to rotate, so that each side of the food on the perforated tray 8 is evenly in contact with the ultraviolet disinfection lamp 31 and the microwave generator 32. At the same time, the air pump 101 sends gas into the hose 102, which is then sprayed out through the air jet pipe 103 and the air jet head 104, blowing the food over and increasing the uniformity and efficiency of food sterilization.
