However, existing constant-current aging machines typically lack drainage functionality. After testing, the water inside the product must be drained to the outside.

DETAILED DESCRIPTION

[0016] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0017] like Figure 1 As shown, the utility model provides an automatic aging constant flow machine with an inflation function, including a machine body, a water injection module 1 and an installation station 2, all of which are arranged on the machine body. The installation station 2 is used to accommodate the product, and the water injection module 1 is used to circulate water into the product. The water injection module 1 is connected to the inflation module 3, and the inflation module 3 includes an air inlet 4, a constant pressure tank 5, a control valve assembly 6 and a pressure gauge 7. The air inlet 4 is connected to the water injection module 1 after passing through the constant pressure tank 5 and the control valve assembly 6. The pressure gauge 7 is used to sense the air pressure value of the air inlet 4.

[0018] The water injection module 1 of the present invention is connected to the product, and circulating water is continuously injected into the product through the water injection module 1 to achieve the aging test. When the test is completed, the water injection module 1 stops injecting water, and then the inflation module 3 inflates the product, and the gas squeezes the water in the product into the water injection module 1, thereby completing the water discharge from the product.

[0019] In addition, the present invention ensures the stability of inflation by setting up a constant pressure tank 5, that is, when the air pressure becomes unstable, by allowing excessive gas to enter the constant pressure tank 5 or the constant pressure tank 5 inputs gas to the air inlet 4 to compensate for insufficient gas.

[0020] In this embodiment, the control valve assembly 6 includes a first control valve 61 and a second control valve 62. The two ends of the first control valve 61 are respectively connected to the constant pressure tank 5 and the water injection module 1. The second control valve 62 and the first control valve 61 are connected in parallel between the constant pressure tank 5 and the water injection module 1. The maximum flow of the first control valve 61 is greater than the maximum flow of the second control valve 62.

[0021] In actual use, both the first control valve 61 and the second control valve 62 are solenoid valves. Initially, the first control valve 61 is opened and the second control valve 62 is closed, allowing a large flow of gas to quickly enter the product, thereby squeezing out the water within the product. When the gas within the product reaches a certain level, the second control valve 62 is opened and the first control valve 61 is closed, allowing a small flow of gas to gradually fill the product interior. This ensures that the remaining water steadily enters the water injection module 1, preventing damage to the product caused by an excessively rapid increase in internal air pressure.

[0022] In addition, the flow rates of the first control valve 61 and the second control valve 62 are different, and inflation and drainage can be achieved for products of different specifications, thereby improving the flexibility of the present invention.

[0023] In this embodiment, a one-way valve 8 is provided between the control valve assembly 6 and the water injection module 1 to ensure that the water in the water injection module 1 and the gas in the inflation module 3 will not flow back to the constant pressure tank 5 / air inlet 4, thereby ensuring safety.

[0024] In this embodiment, an oil-gas separator 9 is provided between the constant pressure tank 5 and the air inlet 4 to allow the gas entering the present invention to absorb the impurities in the gaseous oil, thereby preventing the oil and water from mixing and entering the water injection module 1 to bring safety risks.

[0025] In this embodiment, the water injection module 1 is provided with a first connecting pipe 11 and a second connecting pipe 12, which are respectively used to connect the products on the installation station 2; the first connecting pipe 11 is connected to the inflation module 3, and the first connecting pipe 11 is provided with a water pressure switch 13.

[0026] That is, the water injection module 1 forms a closed loop with the product through the first connecting pipe 11 and the second connecting pipe 12. When the water injection is completed, the water pressure switch 13 is closed due to the reduction of the pressure exerted by the water, thereby blocking the water from entering the first connecting pipe 11; then the inflation module 3 works, allowing gas to enter the product through the first connecting pipe 11, squeezing the water in the product into the second connecting pipe 12 and being discharged.

[0027] Specifically, the first and second connecting pipes 11, 12 are each provided with a pneumatic angle seat valve 14, and the second connecting pipe 12 is also provided with a water filter 15. The pneumatic angle seat valve 14 controls the flow resistance between the product and the first connecting pipe 11, and between the product and the second connecting pipe 12. The water filter 15 filters the water flowing out of the product each time to absorb impurities mixed in the water that are carried out from the product.

[0028] Of course, in actual application, the water injection module 1 should have an exhaust structure for exhausting the gas in the water injection module 1 to ensure that when the aging test is performed, the water injection module 1 will not affect the test effect due to excessive gas.

[0029] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention is disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of the above-disclosed technical contents without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments according to the technology of the present invention, which do not depart from the content of the technical solution of the present invention, are within the scope of the technical solution of the present invention.
