Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of pretreatment and sterilization devices for storing fresh walnuts, and in particular to a pretreatment and sterilization device for storing fresh walnuts. Background Technology
[0002] A pulsed ultraviolet (PLU) sterilization chamber is an instrument used for sterilization. Pulsed light technology utilizes a xenon lamp to release a wide-spectrum, high-energy pulse of light (reaching hundreds of thousands of times the intensity of sunlight reaching the ground) in the form of light radiation within an extremely short time (tens to hundreds of microseconds). This pulsed light kills harmful microorganisms such as viruses, fungi, and bacteria. Sterilization chambers are often used to sterilize fresh walnuts during storage. The fresh walnuts are placed inside the chamber, and the xenon lamp is activated to irradiate and sterilize them.
[0003] The inventors discovered during routine use of the sterilization box that when sterilizing fresh walnuts, a sterilization frame needs to be placed inside the sterilization box. Since the inner wall of the sterilization box is equipped with xenon lamps, the sterilization frame may collide with and damage the xenon lamps during placement, thus preventing sterilization and causing problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pretreatment and sterilization device for storing fresh walnuts.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pretreatment sterilization device for storing fresh walnuts, comprising a sterilization box, a sterilization frame inside the sterilization box, a xenon lamp on the inner wall of the sterilization box, a box lid on the top of the sterilization box, a limiting device on the side of the sterilization box, the limiting device comprising a rectangular plate on the side of the sterilization box, a threaded rod threadedly connected to the side of the rectangular plate, a pressing plate rotatably connected to one end of the threaded rod, and a limiting plate slidably connected to the surface of the rectangular plate.
[0006] The aforementioned components achieve the following effects: the limiting plate prevents the sterilization frame from colliding with the xenon lamp when placed inside the sterilization chamber, thus avoiding damage to the xenon lamp; the threaded rod presses the extrusion plate against the side of the sterilization chamber, thereby achieving a fixing effect. When storing fresh walnuts, sterilization is required. Place the fresh walnuts inside the sterilization frame, then place the sterilization frame inside the sterilization chamber, close the lid, connect the power supply, and the xenon lamp will emit pulsed light, thereby achieving a sterilization effect through high-intensity, short-duration pulsed light radiation.
[0007] Preferably, a locking rod is inserted into the top of the rectangular plate, and a circular groove is formed on the surface of the limiting plate. The circular grooves are evenly arranged on the surface of the limiting plate, and one end of the locking rod is inserted into the interior of the circular groove.
[0008] The effect achieved by the above components is that, under the action of the circular groove and the locking rod, the length of the limiting plate can be adjusted, thereby allowing the limiting device to be adapted to sterilization frames of different sizes.
[0009] Preferably, a round rod is fixedly connected to the side of the extrusion plate, and the round rod is slidably connected to the surface of the rectangular plate.
[0010] The effect achieved by the above components is that, under the action of the round rod, the extrusion plate will not rotate with the rotation of the threaded rod.
[0011] Preferably, the side of the limiting plate is provided with a groove, and a ball bearing is rotatably connected inside the groove.
[0012] The aforementioned components achieve the following effects: Under the action of the ball bearings, the friction between the limiting plate and the sterilization frame is reduced, thus facilitating the insertion of the sterilization frame into the sterilization chamber. When the sterilization frame needs to be positioned, the rectangular plate is placed against the side of the sterilization chamber, and the threaded rod is rotated by hand to make the side of the extrusion plate fit against the inner wall of the sterilization chamber, thereby locking the limiting plate against the side of the sterilization chamber. Under the action of the round rod, the extrusion plate will not rotate with the rotation of the threaded rod. When the limiting plate needs to be adjusted, the locking rod is pulled out, and the limiting plate is slid along the side of the rectangular plate. After sliding to the appropriate position, the locking rod is inserted into the round groove, thus fixing the limiting plate. Under the action of the ball bearings, the friction between the limiting plate and the sterilization frame is reduced, thus facilitating the insertion of the sterilization frame into the sterilization chamber, thereby achieving the limiting function.
[0013] Preferably, the sterilization chamber is provided with a storage device inside. The storage device includes a rectangular groove formed in the inner wall of the sterilization chamber. A bracket is rotatably connected to the inner wall of the rectangular groove, and a xenon lamp is fixedly connected to the side of the bracket.
[0014] The effect achieved by the above components is that, with the help of the bracket and the rectangular slot, the xenon lamp can be stored away when not in use, thus avoiding damage.
[0015] Preferably, a baffle is slidably connected to the inner wall of the rectangular groove, a magnetic block is fixedly connected to the bottom of the baffle, and an iron sheet is fixedly connected to the inner wall of the rectangular groove.
[0016] The effect achieved by the above components is as follows: under the action of the baffle, the xenon lamp can be confined inside the rectangular slot after being stored. Under the action of the iron sheet and the magnetic block, the baffle can block the airflow from the opening of the rectangular slot, thus preventing the xenon lamp from detaching from the inside of the rectangular slot.
[0017] Preferably, a locking rod is inserted into the side of the bracket, and a groove is formed on the inner wall of the rectangular groove, with one end of the locking rod inserted into the groove.
[0018] The effect achieved by the above components is that, under the action of the locking rod, the bracket can be fixed after it rotates out from the inside of the rectangular groove, thereby achieving the function of fixing the bracket.
[0019] Preferably, a spring is sleeved on the surface of the locking rod, and the two ends of the spring are fixedly connected to one end of the locking rod on the side of the bracket.
[0020] The aforementioned components achieve the following effects: Under the action of the spring, the locking rod will not slip out of the groove, thus preventing the bracket from shifting. When the sterilization box is not in use, the locking rod can be pulled out of the groove, the bracket can be rotated into the rectangular slot, and the baffle can be pulled down to magnetically connect the magnet and the iron plate, thereby storing the xenon lamp and preventing damage. When the sterilization box is in use, the baffle is waxed, the bracket can be rotated out of the rectangular slot, and after the bracket is rotated out, the locking rod can be inserted into the groove. Under the action of the spring, the locking rod will not slip out of the groove, thus preventing the bracket from shifting, thereby achieving the function of fixing the bracket and storing the xenon lamp.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting a limiting device, when it is necessary to limit the sterilization frame, the rectangular plate is attached to the side of the sterilization box, and the threaded rod is rotated by hand to make the side of the extrusion plate fit against the inner wall of the sterilization box, thereby locking the limiting plate in the side of the sterilization box. Under the action of the round rod, the extrusion plate will not rotate with the rotation of the threaded rod. When it is necessary to adjust the limiting plate, the locking rod is pulled out, and the limiting plate slides on the side of the rectangular plate. When it slides to the appropriate position, the locking rod is inserted into the inside of the round groove, thereby achieving the function of fixing the limiting plate. Under the action of the ball, the friction between the limiting plate and the sterilization frame is reduced, thereby making it easier to put the sterilization frame into the sterilization box, thus achieving the limiting function and solving the problem that the xenon lamp installed on the inner wall of the sterilization box may be damaged by collision when placing the sterilization frame.

[0028] Working principle: When fresh walnuts need to be stored, sterilization is required. Place the fresh walnuts inside the sterilization frame 6, place the sterilization frame 6 inside the sterilization box 1, close the box lid 5, connect the power supply, and make the xenon lamp 4 emit pulsed light, thereby achieving the sterilization effect through high-intensity, short-time pulsed light radiation.
[0029] Reference Figure 2 The limiting device 2 includes a rectangular plate 21 disposed on the side of the sterilization chamber 1. A threaded rod 22 is threadedly connected to the side of the rectangular plate 21. One end of the threaded rod 22 is rotatably connected to a pressing plate 23. A limiting plate 25 is slidably connected to the surface of the rectangular plate 21. A locking rod 26 is inserted into the top of the rectangular plate 21. A circular groove 27 is formed on the surface of the limiting plate 25. The circular grooves 27 are evenly arranged on the surface of the limiting plate 25. One end of the locking rod 26 is inserted into the interior of the circular groove 27. A circular rod 24 is fixedly connected to the side of the pressing plate 23. The circular rod 24 is slidably connected to the surface of the rectangular plate 21. A groove is formed on the side of the limiting plate 25. A ball bearing 28 is rotatably connected inside the groove.
[0030] Working principle: When it is necessary to limit the sterilization frame 6, the rectangular plate 21 is attached to the side of the sterilization box 1, and the threaded rod 22 is rotated by hand to make the side of the extrusion plate 23 fit against the inner wall of the sterilization box 1, thereby locking the limiting plate 25 on the side of the sterilization box 1. Under the action of the round rod 24, the extrusion plate 23 will not rotate with the rotation of the threaded rod 22. When it is necessary to adjust the limiting plate 25, the locking rod 26 is pulled out, and the limiting plate 25 slides on the side of the rectangular plate 21. After sliding to the appropriate position, the locking rod 26 is inserted into the inside of the round groove 27, thereby achieving the function of fixing the limiting plate 25. Under the action of the ball bearing 28, the friction between the limiting plate 25 and the sterilization frame 6 is reduced, thereby making it easier for the sterilization frame 6 to be put into the sterilization box 1, thus achieving the function of limiting.
[0031] Reference Figure 3 The sterilization box 1 is equipped with a storage device 3 inside. The storage device 3 includes a rectangular groove 31 opened in the inner wall of the sterilization box 1. A bracket 32 is rotatably connected to the inner wall of the rectangular groove 31. A xenon lamp 4 is fixedly connected to the side of the bracket 32. A baffle 33 is slidably connected to the inner wall of the rectangular groove 31. A magnetic block is fixedly connected to the bottom of the baffle 33. An iron sheet 34 is fixedly connected to the inner wall of the rectangular groove 31. A locking rod 35 is inserted into the side of the bracket 32. A groove is opened in the inner wall of the rectangular groove 31. One end of the locking rod 35 is inserted into the groove. A spring 36 is sleeved on the surface of the locking rod 35. The two ends of the spring 36 are fixedly connected to the side of the bracket 32 and one end of the locking rod 35, respectively.
[0032] Working principle: When the sterilization box 1 is not in use, the locking rod 35 is pulled out from the inside of the groove, the bracket 32 is rotated into the inside of the rectangular groove 31, and the baffle 33 is pulled down, so that the magnet and the iron plate 34 are magnetically connected together, thereby storing the xenon lamp 4 and avoiding damage. When the sterilization box 1 is in use, the baffle 33 is waxed, the bracket 32 is rotated out from the inside of the rectangular groove 31, and after the bracket 32 is rotated out, the locking rod 35 is inserted into the inside of the groove. Under the action of the spring 36, the locking rod 35 will not slip out from the inside of the groove, thereby preventing the bracket 32 from shifting, thus achieving the function of fixing the bracket 32 and thus achieving the function of storing the xenon lamp 4.
