[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0022] like Figures 1 to 3As shown, the embodiment of the present invention preferably provides a frame 1, on which at least one partition 2 is provided, and a positioning area 61 for positioning and placing a power supply base is provided on the partition 2; a placement frame 3, which is arranged above the partition 2 and can move up and down relative to the partition 2, and a slot 4 for placing a disinfection tray 62 is provided on the corresponding positioning area 61; a driving member 5, which is arranged on the frame 1, including a lifting frame 7 and a driving member 8 for driving the lifting frame 7 to move up and down; wherein the lifting frame 7 includes at least two vertically spaced The guide shaft 9 and the fixed plate 10 connected between the two guide shafts 9, the driving member 8 is arranged on the frame 1 and its driving shaft is connected to the fixed plate 10, the placement rack 3 is movably sleeved on the two guide shafts 9, and a limiting member 11 for supporting the placement rack 3 is provided on the guide shaft 9 corresponding to the lower part of the placement rack 3, the guide shaft 9 is a screw, and the limiting member 11 is threadedly sleeved on the guide shaft 9, and the height spacing of the placement rack 3 relative to the partition 2 is adjusted by the limiting member 11 along the axial thread movement of the guide shaft 9. Specifically, by placing the fruit and vegetable disinfection tray in the slot of the placement rack, and then placing the power supply base that matches the fruit and vegetable disinfection tray in the positioning area of ​​the interlayer below the slot, and then driving the placement rack to move up and down through the driving component, the fruit and vegetable disinfection tray and the power supply base are continuously connected and separated, so as to realize the detection of the service life of the fruit and vegetable disinfection tray and the power supply base being powered on and off; and the operator can adjust the distance between the placement rack and the interlayer according to the fruit and vegetable disinfection trays of different heights and sizes; and the placement racks and fixed plates located in different test areas can be adjusted accordingly, so that each layer can test the fruit and vegetable disinfection trays of the same height and size or the fruit and vegetable disinfection trays of different heights and sizes, thereby enhancing the applicability of the structure. During specific implementation, the fruit and vegetable disinfection tray is placed in the slot hole of the placement rack, and it is known from the attached figure of the specification of Chinese Patent Publication No. CN113243721A that the fruit and vegetable disinfection tray has an inverted trapezoidal cross-section, and then when the fruit and vegetable disinfection tray is placed in the slot hole, the lower end of the fruit and vegetable disinfection tray and the power supply base are connected to the bottom of the placement rack, and then the placement rack is movably sleeved on one of the two guide shafts and limited by the limiting member, and then when the driving member drives the lifting frame to move upward, the limiting member pushes the placement rack to move upward, thereby driving the fruit and vegetable disinfection tray on the placement rack to move upward and separate from the power supply base provided on the interlayer, and when the driving member drives the lifting frame to move downward, the placement rack moves downward under the action of its own weight, so that when the fruit and vegetable disinfection tray moves downward with the placement rack under its own weight, the fruit and vegetable disinfection tray continues to move downward due to the placement rack. After it is connected with the power supply base for power supply, the fruit and vegetable disinfection tray separates from the placement rack and is limited by the fixed plate.

[0023] In another embodiment, the test device further includes: a rotating member 6, which is disposed on the fixed plate 10 and is used to drive the fruit and vegetable disinfection disk in the slot 4 to rotate. Specifically, the rotating member is used to drive the fruit and vegetable disinfection disk in the slot to rotate, and then the fruit and vegetable disinfection disk is continuously rotated to simulate the power supply docking of the fruit and vegetable disinfection disk with the power supply base at random positions during use.

[0024] Furthermore, there are several partitions 2, which are vertically spaced and arranged on the frame 1, so that several layers of test areas are formed on the frame 1, and the two guide shafts 9 are sequentially arranged on each partition 2; there are several placement racks 3, which are movably sleeved on the two guide shafts 9 of each test area in a one-to-one correspondence; there are several limiters 11, which are respectively arranged on the guide shafts 9 below each placement rack 3 in a one-to-one correspondence. Specifically, by correspondingly arranging several partitions, placement racks and limiters, a multi-layer test area can be implemented to perform docking and separation tests on multiple fruit and vegetable disinfection trays and power supply bases, and the guide shaft of the lifting rack is arranged on the multi-layer test area, so that a single lifting rack can be lifted and moved to achieve docking and separation of multiple layers of fruit and vegetable disinfection trays and power supply bases.

[0025] Furthermore, the fixed plates are provided with a plurality of them, which are movably sleeved between the two guide shafts above each placement rack. Nuts are threadedly connected on the upper and lower sides of each fixed plate on the guide shaft. The two nuts are threadedly moved along the axial thread of the guide shaft to clamp and adjust the height spacing of the fixed plate relative to the partition. The operator can adjust the spacing between the fixed plate and the partition according to the fruit and vegetable disinfection trays of different heights, thereby adjusting the spacing between the rotating component on the fixed plate and the fruit and vegetable disinfection tray on the placement rack.

[0026] Furthermore, the rotating member 6 includes a reduction motor 12 disposed on the fixed plate 10, and a friction member 13 disposed on the driving shaft of the reduction motor 12 for frictionally abutting against the inner wall of the disinfection tray 62. Specifically, the friction member moves downward with the fixed plate to frictionally abut against the inner wall of the fruit and vegetable disinfection tray, and when the reduction motor drives the friction member to rotate, the friction member drives the fruit and vegetable disinfection tray to rotate through friction force, so as to realize the power supply docking of the fruit and vegetable disinfection tray with the power supply base at random positions when the fruit and vegetable disinfection tray is used in a simulated rotation.

[0027] Furthermore, the friction member 13 includes a shaft body 15 connected to the drive shaft of the reduction motor 12, a side wing 14 connected to at least one side of the shaft body 15, and a silicone member sleeved on the side wing 14 for abutting against the inner wall of the disinfection tray. The silicone member abuts against the inner wall of the fruit and vegetable disinfection tray through friction, and then when the silicone member rotates with the side wing around the shaft body, the friction drives the fruit and vegetable disinfection tray to rotate.

[0028] Furthermore, when the placement rack 3 abuts against the limiting member 11, the vertical height between the placement rack 3 and the fixed plate 10 is greater than the sum of the height of the friction member 13 and the height of the disinfection tray. Thus, when the fruit and vegetable disinfection tray on the placement rack and the power supply base on the partition are in an initial state of separation, it is convenient to take and place the fruit and vegetable disinfection tray in the slot of the placement rack.

[0029] Furthermore, a connecting plate 16 is provided on the driving shaft of the driving member 8, and the connecting plate 16 is connected to the fixing plate 10 located at the uppermost part of the lifting frame 7. A guide shaft 17 is vertically spaced apart on the connecting plate 16, and the guide shaft 17 is movably inserted into the frame 1 through a linear bearing.

[0030] Furthermore, the driving member 8 is a cylinder.
