Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of spray leakage detection equipment, and more specifically, to a spray leakage detection device. Background Art
[0002] Sprays refer to raw materials or drugs filled with suitable excipients in a special device. When used, the contents are released in the form of mist using methods such as pressure from a manual pump or high-pressure gas. Bear sprays usually contain spicy and irritating substances extracted from natural plants, such as pepper essential oil, which can irritate the eyes, nose and respiratory tract of bears, causing extreme discomfort, thereby having the effect of repelling bears in the wild. After the spray is filled into the bottle, it needs to be leak-tested by leak detection equipment to avoid loose seals and low product quality.
[0003] The existing leak detection method includes the differential pressure color water bath method, which is to place the capped spray bottle in water with a color that is significantly different from the drug for a period of time. After that, the drug is taken out to see if the colored water has entered the drug. Manual judgment on whether the drug has leaked is performed, resulting in low efficiency, long testing cycle, complicated process, and requiring a large amount of raw materials and labor.
[0004] After searching, a Chinese patent with authorization announcement number CN218674140U discloses a spray leak detection device. The structure connects each gas connector three to the gas connector one at the bottom of a leak detection unit through a hose, and the gas connector two is connected to the negative pressure tank through a hose. The negative pressure tank provides negative pressure for the leak detection unit. The negative pressure creates a pressure difference between the inside and outside of the spray bottle, accelerating the leakage of the spray bottle with poor sealing, thereby realizing leak detection of the spray bottle, and then used to detect the sealing integrity of the spray bottle. It has the advantages of convenient detection and easy operation.
[0005] However, in actual use, this structure improves the sealing performance by providing two sealing rings, and the sealing rings are provided on the inner wall of the leak detection cover. However, since the leak detection cover does not completely wrap the surface of the spray bottle, and only the sealing rings are used to seal the leak detection cover and the spray bottle, it is easy to cause only the front half of the spray bottle to be leak-tested during the pressurization process, thereby affecting the accuracy of the overall detection.

By observing the size, shape and formation rate of the bubbles, the severity of the leakage can be further reflected, thereby realizing leak detection of the spray bottle body.

[0028] Reference Figure 2-3As shown, a detection mechanism is fixedly provided inside the lower inflatable hood 5, and the detection mechanism includes a fixing ring 16 fixedly provided inside the lower inflatable hood 5, and a sealing ring 17 is provided on the surface of the fixing ring 16.

A delivery pipe 19 is fixedly provided on one side of the branch conduit 18, and a butterfly valve 20 is fixedly provided on one side of the delivery pipe 19. A main connection box 21 is fixedly provided at one end of the delivery pipe 19. By starting the vacuum pump 24 and opening the butterfly valve 20, the vacuum is discharged from the bottom of the lower inflatable hood 5. The air in the enclosed space formed by the lower inflatable hood 5 and the upper inflatable hood 8 is sucked into the inside of the delivery pipe 19 through the branch duct 18, and is delivered to the inside of the main connection box 21 by the delivery pipe 19. Then, the air enters the inside of the main duct 22 through the main connection box 21, and then enters the inside of the negative pressure tank 23 through the main duct 22. The air is then delivered to the vacuum pump 24 through the connecting pipe 25 and discharged outward, thereby forming a certain negative pressure environment inside the enclosed space formed by the lower inflatable hood 5 and the upper inflatable hood 8. The negative pressure causes a pressure difference between the inside and outside of the spray bottle body, which accelerates the leakage of the spray bottle body that is not well sealed.
[0029] Reference Figure 4-6 As shown, a main conduit 22 is fixedly provided at the bottom of the main connection box 21, one end of the main conduit 22 passes through the fixing frame 1 and extends to the outside of the fixing frame 1, and a negative pressure tank 23 is fixedly installed at one end of the main conduit 22.

If gas leakage is found, the special leak detection liquid inside the lower inflatable cover 5 forms bubbles at the leakage point, thereby accurately indicating the leakage position. By observing the size, shape and formation rate of the bubbles, the severity of the leakage can be further reflected, thereby realizing leak detection of the spray bottle body.
[0030] Working principle of this utility model:
[0031] The utility model is a spray leak detection device. When using the device, the press nozzle of the spray bottle body to be detected is first placed downward on the fixing ring 16 inside the lower inflatable cover 5, and the sealing ring 17 provided on the surface of the fixing ring 16 prevents the subsequent gas in the negative pressure environment from squeezing the nozzle of the spray bottle body, thereby effectively avoiding the nozzle of the spray bottle body and improving the accuracy of detection. Then, a special leak detection liquid, such as detergent, soap liquid or special leak detection agent, is poured into the interior of the lower inflatable cover 5, and then the upper inflatable cover 8 is moved downward to be sleeved on the surface of the spray bottle body, and the sealing ring 7 is inserted into the interior of the sealing groove 6, thereby improving the sealing effect and stability. At the same time, the upper inflatable cover 8 is moved during the process of During the movement, the fixing hooks 10 on both sides of the upper inflatable cover 8 are also driven downward, thereby being inserted into the interior of the fixing frame 11, and then the bolts 12 are rotated forward to drive the bolts 12 into the interior of the fixing frame 11 and the fixing hooks 10, thereby fixing the fixing frame 11 and the fixing hooks 10. Moreover, the rubber layer 15 inside the upper inflatable cover 8 is also in contact with the bottom of the spray bottle body, and the rubber layer 15 effectively plays an anti-slip effect, while also preventing damage to the surface of the spray bottle body. In the process of moving the upper inflatable cover 8, the rubber layer 15 moves and drives the pressure plate 14 to be squeezed and moved upward. At the same time, the movement of the pressure plate 14 causes the spring 13 to be squeezed and deformed, thereby fixing the spray bottle body, thereby further improving stability.
[0032] After the installation is completed, by starting the vacuum pump 24 and opening the butterfly valve 20, the air in the enclosed space formed by the lower inflatable hood 5 and the upper inflatable hood 8 is sucked into the inside of the delivery pipe 19 through the branch duct 18, and the delivery pipe 19 is delivered to the inside of the main connection box 21, and then enters the inside of the main duct 22 through the main connection box 21, and then enters the inside of the negative pressure tank 23 through the main duct 22, and is then delivered to the vacuum pump 24 through the connecting pipe 25 and discharged outward, so that a certain negative pressure environment is formed in the enclosed space formed by the lower inflatable hood 5 and the upper inflatable hood 8. The negative pressure causes a pressure difference between the inside and outside of the spray bottle body, which accelerates the leakage of the spray bottle body with poor sealing;
[0033] When the spray bottle body leaks, the leak location can be more intuitively observed through the observation glass 9. If gas leakage is found, the special leak detection liquid inside the lower inflation cover 5 will form bubbles at the leak point, thereby accurately indicating the leak location. By observing the size, shape and formation rate of the bubbles, the severity of the leak can be further reflected, thereby realizing the leak detection of the spray bottle body.
[0034] Leak testing the spray bottle body can ensure that its sealing performance is good and there is no risk of leakage, which will help improve the effectiveness of the spray bottle in the wild, thereby enhancing the bear protection effect and reducing safety hazards caused by product failure.
[0035] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
