[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-7 The utility model discloses a decontamination testing machine for convenient decontamination, including a machine body 1, on which a plurality of telescopic rods 2 are rotatably arranged, a driving device for driving the telescopic rods 2 to rotate is arranged in the machine body 1, the driving device includes a motor and a sprocket group, the sprocket group includes a plurality of sprockets and chains connected to the sprockets, one of the sprockets is connected to the rotating shaft of the motor, and the other sprockets are connected to the plurality of telescopic rods 2, when the motor is started, the plurality of telescopic rods 2 can be synchronously rotated and adjusted through chain transmission.

[0030] In one embodiment, a plurality of water bath bins 3 are embedded in the machine body 1, each of which is sequentially located below the corresponding telescopic rod 2, and each of which is provided with a support 5, on which a linkage part is rotatably installed, and the linkage part is located in the water bath bin 3, and a reciprocating screw 7 is rotatably provided at the bottom of the linkage part, and an impeller 16 is installed at the bottom of the reciprocating screw 7, and a wall scraping ring frame 12 in contact with the inner wall of the water bath bin 3 is sleeved on the linkage part, and the wall scraping ring frame 12 cooperates with the reciprocating screw 7, and the reciprocating screw 7 rotates to drive the wall scraping ring frame 12 to reciprocate along the height direction of the water bath bin 3. Movement, an unlocking device is slidably inserted in the reciprocating screw 7, and a locking device 13 that coincides with the reciprocating screw 7 is installed on the inner bottom wall of the water bath chamber 3. The locking device 13 is inserted upward into the reciprocating screw 7 to lock the reciprocating screw 7 so that it does not rotate synchronously with the linkage part. The telescopic rod 2 is extended downward and inserted into the linkage part to drive the linkage part to rotate. The telescopic rod 2 continues to extend into the reciprocating screw 7 and pushes the unlocking device downward, so that the unlocking device squeezes the locking device 13 out of the reciprocating screw 7, which is used to unlock the reciprocating screw 7 and rotate synchronously with the linkage part.

[0031] In a specific implementation, the stained fabric, detergent and water are put into the water bath chamber 3, and then the telescopic rod 2 is adjusted to make it descend and plugged into the linkage part and the reciprocating screw 7, so that the telescopic rod 2 pushes the unlocking device downward, and the unlocking device squeezes the locking device 13 out of the reciprocating screw 7. At this time, the reciprocating screw 7 will rotate synchronously with the linkage part. Then, the linkage part is driven to rotate by the driving device. At this time, the reciprocating screw 7 and its scraper ring frame 12 rotate synchronously, and the impeller 16 rotates accordingly and stirs the water and fabric inside the water bath chamber 3 to wash the fabric in the water bath chamber 3, thereby facilitating the measurement of the decontamination performance of the detergent. Yes, when it is necessary to clean the inner wall of the water bath chamber 3, the telescopic rod 2 is adjusted to be inserted only into the linkage part. At this time, the unlocking device will not work, so that the locking device 13 is inserted into the reciprocating screw 7 to lock it, and then the linkage part is driven to rotate by the driving device. At this time, the scraper ring frame 12 will rotate synchronously, while the reciprocating screw 7 will not rotate. The rotating scraper ring frame 12 cooperates with the reciprocating screw 7 so that it can reciprocate along the height direction of the water bath chamber 3. With this design, the residual stains on the inner wall of the water bath chamber 3 can be scraped off, thereby efficiently cleaning the water bath chamber 3 of the decontamination tester to ensure the accuracy of the decontamination test.

[0032] In one embodiment, a drain pipe 4 is disposed at the bottom of each water bath chamber 3 , and a drain pipeline (not shown in the figure) communicating with the discharge end of each drain pipe 4 is disposed in the machine body 1 .

[0033] With this design, when there is water but no fabric inside the water bath chamber 3, the water in each water bath chamber 3 can be discharged through the drainage pipe. In actual circumstances, a switch valve is provided on the drainage pipe, and whether the water in the water bath chamber 3 is discharged is determined by controlling the start and stop of the switch valve.

[0034] In one embodiment, the telescopic rod 2 includes a sleeve 21 connected to the power end of the driving device, a hexagonal pin 22 slidably inserted in the sleeve 21, a limit rod 23 slidably and telescopically inserted on the hexagonal pin 22, and two locking holes 24 opened on the sleeve 21. The two locking holes 24 are located at different heights on the sleeve 21. A spring is arranged in the hexagonal pin 22, and the other end of the spring is connected to the limit rod 23. The limit rod 23 is inserted into each locking hole 24 for limiting the hexagonal pin 22 extending to different heights outside the sleeve 21. Locking grooves 9 are opened in the linkage part and at the top and bottom ends of the reciprocating screw 7. The hexagonal pin 22 cooperates with the locking grooves 9 in the linkage part and at the top of the reciprocating screw 7.

[0035] In the specific implementation, the limiting rod 23 is pressed into the hexagonal pin 22 so that it is separated from the locking hole 24, and then the hexagonal pin 22 can be pulled downward. When the limiting rod 23 is supported by the spring and inserted into the locking hole 24, the hexagonal pin 22 can be limited. There are two locking holes 24. With this design, the hexagonal pin 22 can slide outward from the sleeve 21 to two positions and be limited. These positions correspond to being inserted into the locking groove 9 on the linkage part, and being inserted into the locking groove 9 at the top of the linkage part and the reciprocating screw 7. The shape of the locking groove 9 is adapted to the hexagonal pin 22. Therefore, when the telescopic rod 2 rotates, the linkage part or the reciprocating screw 7 will also be driven to rotate.

[0036] In one embodiment, the locking device 13 includes a mounting sleeve 131 arranged on the inner bottom wall of the water bath chamber 3 and a hexagonal column 132 slidably inserted into the mounting sleeve 131. A spring is installed inside the mounting sleeve 131, and the other end of the spring is connected to one end of the hexagonal column 132. When in use, the spring pushes the hexagonal column 132 upward, so that the other end of the hexagonal column 132 is inserted into the locking groove 9 at the bottom end of the reciprocating screw 7.

[0037] With this design, when the hexagonal column 132 is inserted into the locking groove 9 at the bottom end of the reciprocating screw 7, the reciprocating screw 7 will not rotate synchronously with the linkage part. When the hexagonal pin 22 is inserted into the locking groove 9 at the top end of the reciprocating screw 7, it will simultaneously push the unlocking device, and the unlocking device will push the hexagonal column 132 downward, so that the hexagonal column 132 will retract into the mounting sleeve 131, so that the reciprocating screw 7 will not be locked by the locking device 13, but will rotate synchronously with the hexagonal pin 22.

[0038] In one embodiment, the scraper ring frame 12 is annular in shape and has a plurality of filter holes therein. The scraper ring frame 12 is wrapped with an anti-scratch layer, which may be a rubber layer.

[0039] This design allows the scraper ring frame 12 to reciprocate to scrape the stains on the inner wall of the water bath chamber 3, and the water can directly pass through the filter holes to reduce the resistance of the scraper ring frame 12 to rise and fall in the water. The anti-scratch layer is used to prevent the scraper ring frame 12 from scratching the surface of the fabric when it rotates. At the same time, when the scraper ring frame 12 rotates, the anti-scratch layer will also contact different parts of the fabric, thereby simulating the function of wiping the fabric to remove dirt.

[0040] In one embodiment, a storage groove 15 with an annular shape is provided on the scraper ring frame 12 , and the storage groove 15 is used to store impurities scraped off the inner wall of the water bath chamber 3 by the scraper ring frame 12 .

[0041] With this design, when there is no water or fabric inside the water bath chamber 3, the scraper ring frame 12 is controlled to move back and forth to scrape the stains on the inner wall of the water bath chamber 3, and the stains will remain in the storage tank 15. The staff can control the scraper ring frame 12 to move to the upper side of the water bath chamber 3 to facilitate the removal of the stains, thereby preventing excessive stains from being discharged into the drainage pipe through the drain pipe 4 and adhering to or even blocking the drainage pipe.

[0042] In one embodiment, the unlocking device includes a rod body 10 slidably inserted into the reciprocating screw 7 and a return spring 11 disposed in the reciprocating screw 7 , and the other end of the return spring 11 is connected to the rod body 10 .

[0043] With such a design, when the hexagonal pin 22 is inserted into the locking groove 9 at the top end of the reciprocating screw 7, it will simultaneously push one end of the rod body 10, and the other end of the rod body 10 will push the hexagonal column 132 to retract it into the mounting sleeve 131. When the hexagonal pin 22 is not in contact with the rod body 10, the reset spring 11 is used to drive the rod body 10 to reset so that the rod body 10 is not in contact with the hexagonal column 132.

[0044] In one embodiment, the linkage part includes a fixed sleeve 6 arranged at the center of the water bath chamber 3 and a stirring frame 8 installed on the fixed sleeve 6, a locking groove 9 is opened in the fixed sleeve 6, and a scraper ring frame 12 is sleeved on the stirring frame 8, a control panel 14 is installed on the machine body 1, and the control panel 14 is used to control the start and stop of the driving device, and a kneading groove (not shown in the figure) is opened on the stirring frame 8, and the kneading groove has a corrugated shape.

[0045] With this design, when the telescopic rod 2 drives the linkage part and the reciprocating screw 7 to rotate synchronously, the stirring frame 8 will also rotate synchronously. At this time, since the stirring frame 8 is provided with a kneading groove, the rotating fabric contacts the kneading groove on the stirring frame 8 to produce a motion similar to manual kneading to simulate the use of a washing machine, thereby further improving the accuracy of the device in simulating a washing machine.
