[0028] Embodiment
[0029] As Figure 1 、 Figure 2 、 Figure 3 And Figure 4As shown in the figure, the present utility model provides a technical solution: a water bath detection device for the air tightness of a tank body, which includes a water bath tester 1. A water bath tank 2 is arranged on the right side of the water bath tester 1, and a cleaning component 3 is installed in the middle of the water bath tank 2. An upper plate 4 is installed at the upper middle part of the cleaning component 3, and a clamping component 5 is arranged in the middle section of the upper plate 4;
[0030] The clamping assembly 5 includes a support seat 501, bolts 502, a snap ring frame 503 and an electric telescopic rod 504. The middle section of the upper plate 4 is provided with a support seat 501, and bolts 502 are inserted on both sides of the support seat 501. A snap ring frame 503 is inserted at the upper end of the support seat 501, and electric telescopic rods 504 are arranged on both sides of the snap ring frame 503. Specifically, the device first places the tank body to be tested in the water bath box 2 of the water bath tester 1, passes through the clamp of the water bath box 2, and clamps the tank body through the clamping assembly 5, and uses the tube body connected to the upper end of the water bath tester 1 to fill a certain amount of test gas, usually air or nitrogen, into the tank body, and records the initial pressure value in the tank body. Next, the tank body is immersed in a constant temperature water bath and kept for a certain time, usually 30 minutes. During the process, the pressure change in the tank body is continuously monitored. Due to the difference in the sealing performance of the tank body, the gas in the tank body gradually escapes through the tiny leakage hole, causing the pressure to drop. By observing the rate of pressure drop, the sealing performance of the tank body can be evaluated. A cleaning component 3 is provided in the middle of the water bath box 2, which is convenient for disassembling and cleaning the inner box 301 inside the water bath box 2, thereby greatly improving the cleaning effect of the water bath box 2. Guide rails 302 are provided on both sides of the inner box 301, and two sets of brush holders 303 are placed on the guide rails 302 on both sides of the inner box 301. The brush holders 303 are moved on the guide rails 302 on both sides of the inner box 301, and the friction force of the brush holders 303 on the inner box 301 is utilized, so that the user can clean the inner box 301 of the water bath tester 1 regularly, and remove the equipment. The dust and dirt on the surface of the equipment are removed. An upper plate 4 is provided at the upper end of the brush holder 303, and a clamping assembly 5 is installed through the upper plate 4, which is convenient for clamping the can body to be inspected and then inspecting. Through the setting of the clamping assembly 5, the can body can be fixed in the center and placed in the water bath to ensure that the can body in the middle of the fixture is completely immersed in water. The performance of the can body in the water bath is observed, and special attention is paid to whether there are bubbles. If bubbles are generated on the surface of the aerosol can during the immersion process, or water droplets condense after being taken out, it can be determined that the air tightness of the aerosol can is poor. The support seat 501 is locked to the upper end of the upper plate 4 by bolts 502 for positioning and locking. The can body is placed on the support seat 501, and the electric telescopic rod 504 is turned on to drive the snap ring frame 503 to engage with the upper end of the support seat 501, so that the can body can be inspected. The body is positioned to prevent the can body from being completely immersed in the water bath box 2 for placement. Through this technical solution, the can body is placed in the airtight water bath detection device for observation, but the can body is placed in the airtight water bath detection device, which easily leads to the can body being placed out of the center and unable to be stably placed in the airtight water bath detection machine for detection and processing. An upper plate 4 is provided at the upper end of the brush holder 303, and a clamping assembly 5 is installed through the upper plate 4, which is convenient for clamping the can body to be detected and then detecting and processing. Through the setting of the clamping assembly 5, the can body can be fixed in the center and placed in the water bath to ensure that the can body in the middle of the fixture is completely immersed in water. The performance of the can body in the water bath is observed, and special attention is paid to whether bubbles are generated. If bubbles are generated on the surface of the aerosol can during the immersion process,Or if there are water droplets condensed after taking it out, it can be judged that the airtightness of the aerosol can is poor.
[0031] Further, such as Figures 1-4 As shown: it also includes and a clamping assembly 5 is provided in the middle section of the upper plate 4. The advantage of this technical solution is that the support seat 501 is locked to the upper end of the upper plate 4 by bolts 502 for positioning and locking, and the tank body is placed on the support seat 501. By turning on the electric telescopic rod 504, the clamping ring frame 503 is driven to engage with the upper end of the support seat 501, and the tank body can be positioned to prevent the tank body from being unable to be completely immersed in the water bath box 2 for placement.
[0032] The above solution also has the problem that it is not convenient to disassemble and clean the interior of the water bath 2. Figures 1-4 As shown: In this scheme, the cleaning component 3 includes an inner box 301, a guide rail 302 and a brush holder 303.

The brush holder 303 is installed in the middle section of the guide rail 302. The device first places the tank body to be tested in the water bath box 2 of the water bath tester 1, passes through the clamp of the water bath box 2, and clamps the tank body through the clamping component 5. A certain amount of test gas, usually air or nitrogen, is filled into the tank body using the tube body connected to the upper end of the water bath tester 1, and the initial pressure value in the tank body is recorded. Next, the tank body is immersed in a constant temperature water bath and maintained for a certain period of time, usually 30 minutes. During this period, the pressure changes in the tank body are continuously monitored. Due to the difference in the sealing performance of the tank body, the gas in the tank body gradually escapes through the tiny leak, resulting in a pressure drop. By observing the speed of the pressure drop, the pressure drop rate is measured. The sealing performance of the tank body can be evaluated by the rate. A cleaning component 3 is provided in the middle of the water bath box 2, which is convenient for disassembling and cleaning the inner box 301 inside the water bath box 2, thereby greatly improving the cleaning effect of the water bath box 2.
