Description

Technical Field

[0001] This utility model relates to the field of disinfectant processing technology, specifically a water injection device for disinfectant processing. Background Art

[0002] Disinfectant is a common disinfection product. There are many types of disinfectants, the most common being sodium chlorate solution, povidone-iodine, and hydrogen peroxide solution. It is mainly used by spraying or applying it to the skin and object surfaces. After use, it can kill bacteria and fungi and other pathogens on the surface of objects. Disinfectants have a wide range of uses. In the disinfectant processing industry, the water injection device is one of the key pieces of equipment, which undertakes the important task of injecting water or disinfectant raw materials into the processing equipment.

[0003] Most existing water injection devices use manual or simple electric valves to control the water volume. This control method lacks precision and stability. In actual operation, operators often need to adjust the valve opening based on experience and intuition to achieve approximate water volume control. However, this control method is not only inefficient, but also makes it difficult to guarantee the accuracy of each water injection, resulting in fluctuations in the concentration and ratio of the disinfectant, which affects the disinfection effect and product quality. Therefore, we need to propose a water injection device for disinfectant processing. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Please see Figure 1-3 , the utility model provides a technical solution:

[0021] A water injection device for disinfectant processing includes a positioning base plate 1, a water injection tank 2 fixedly mounted on the top of the positioning base plate 1, a piston plate 3 slidably connected inside the water injection tank 2, a support plate 4 fixedly connected to the top of the positioning base plate 1, a power assembly 5 for moving the piston plate 3 provided on one side of the support plate 4, one side of the piston plate 3 connected to the movable end of the power assembly 5, two sets of fixing brackets 6 fixedly connected to the top of the positioning base plate 1, a water storage tank 7 fixedly connected to the top of the two sets of fixing brackets 6, a water supply pipe 8 fixedly connected to the outer wall of the water storage tank 7, one end of the water supply pipe 8 fixedly connected to one end of the water injection tank 2, and a first one-way valve 9 conductively connected to the outer wall of the water supply pipe 8, and a water injection pipe fixedly connected to one end of the water injection tank 2. 10. A second one-way valve 11 is connected to the outer wall of the water injection pipe 10. By setting up a positioning base plate 1, a water injection tank 2, a piston plate 3, a support plate 4, a power component 5, a fixing frame 6, a water storage tank 7, a water delivery pipe 8, and a first one-way valve 9, the piston plate 3 can be moved by the power component 5, so that the piston plate 3 moves away from the water delivery pipe 8. This allows water inside the water storage tank 7 to be pumped into the water injection tank 2 through the water delivery pipe 8. After the piston plate 3 has moved a certain distance, the piston plate 3 can be pushed in the opposite direction by the power component 5, so that water inside the water injection tank 2 can be discharged into the disinfectant processing device (not shown in the figure) through the water injection pipe 10, thereby achieving the effect of precise quantitative water injection.

[0022] Specifically, the power assembly 5 includes a ball screw 501. One end of the ball screw 501 is rotatably mounted on one side wall of the water tank 2, and the other end of the ball screw 501 is rotatably mounted on one side wall of the support plate 4. One end of the ball screw 501 passes through the support plate 4 and is connected to a drive motor 502. A movable plate 503 is threadedly connected to the outer wall of the ball screw 501. The output shaft of the drive motor 502 can drive the ball screw 501 to rotate in the forward or reverse direction, thereby driving the movable plate 503 to reciprocate along the axial direction of the ball screw 501.

[0023] Furthermore, it also includes four sets of connecting rods 504. The connecting rods 504 serve as the movable ends of the power assembly 5. One end of each of the four sets of connecting rods 504 is fixedly connected to one side wall of the moving plate 503, and the other end of each of the four sets of connecting rods 504 passes through the water tank 2 and is fixedly connected to one side of the piston plate 3. Each of the four sets of connecting rods 504 is slidably connected to the water tank 2. When the moving plate 503 reciprocates along the axial direction of the ball screw 501, the piston plate 3 can be driven to reciprocate along the axial direction of the water tank 2 through the connecting rods 504.

[0024] It is worth mentioning that the drive motor 502 is fixedly installed on one side wall of the support plate 4, and one end of the output shaft of the drive motor 502 is fixedly connected to one end of the ball screw 501. The drive motor 502 is set as a forward and reverse stepper motor.

[0025] Furthermore, a grating ruler 12 is fixedly connected to the top of the positioning base plate 1, and a reading head 13 is fixedly connected to the bottom of the moving plate 503. By setting the grating ruler 12 and the reading head 13 to work together, the moving distance of the moving plate 503 can be monitored, thereby accurately controlling the moving distance of the piston plate 3.

[0026] It should be noted that two sets of water level sensors 14 are fixedly connected to the inner wall of the water storage tank 7. The water level sensors 14 can monitor the water volume inside the water storage tank 7. A control panel 15 is fixedly connected to the outer wall of the water storage tank 7. The grating ruler 12, the reading head 13, the water level sensor 14 and the drive motor 502 are all electrically connected to the control panel 15 through wires. The circuit connection is a mature existing technology. The specific connection method and working principle will not be described in detail here. The control panel 15 can be set as a microcontroller to receive (feedback) the data information of the water level sensor 14, the grating ruler 12 and the reading head 13. In addition, the control panel 15 can start and stop the drive motor 502.

[0027] Furthermore, a water inlet pipe 16 is fixedly connected to the top of the water storage tank 7, and a sealing cover is attached to the top of the water inlet pipe 16. When the remaining water inside the water storage tank 7 is at a low water level, the staff can add water to the inside of the water storage tank 7 through the water inlet pipe 16 by opening the sealing cover.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
