This device includes at least one air venting support pipe, an air vent pipe, and an air vent pump. One end of the air venting support pipe is connected to one end of the air vent pipe through a mounting hole at the bottom of the water tank. The other end of the air venting support pipe extends upwards into the water tank, and the other end of the air vent pipe is connected to the air inlet of the air vent pump. This invention's automatic air venting and water inlet device automatically fills the container by inserting the air venting support pipe into the container and using the air vent pump to remove air from the container. The device has the advantages of simple structure, ease of use, and automatic drainage.

[0003] Currently, in the cooling pipe systems of both new energy vehicles and gasoline vehicles, the cooling medium generates bubbles as the operating temperature rises. These bubbles occupy the internal space of the pipes, causing increased pressure and hindering the flow of the cooling medium. Since the specific heat capacity of liquids is much greater than that of gases, the presence of bubbles directly reduces the cooling effect of the cooling system, affecting the normal operation of the vehicle. Therefore, there is an urgent need for a connection device that can promptly remove bubbles from the pipes. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic exhaust connection device that can solve the problem of increased pipeline pressure and decreased cooling effect caused by air bubbles generated when the cooling medium heats up in the automotive cooling pipeline system.

[0005] To achieve the above objectives, a specific embodiment of the present invention provides the following technical solution: An automatic venting connection device includes a top cover, a housing, an vent cap, a buoy, an inner sealing ring, an outer sealing ring, a support rod, a support base, a sealing gasket, a compression spring, and an vent column.

[0008] In one or more embodiments of the present invention, the support rod and the sealing gasket are assembled to form a support sub-rod assembly, and the sealing gasket is fixedly installed at one end of the support rod.

[0009] In one or more embodiments of the present invention, the support base is fixed to the bottom wall inside the housing, and the compression spring is sleeved between the support base and the support rod to provide a restoring elastic force for the support rod.

[0010] In one or more embodiments of the present invention, the buoy is movably connected above the support base, and the buoy is in transmission cooperation with the support rod, and the lifting and lowering movement of the buoy can drive the support rod to rotate around the connection point.

[0011] In one or more embodiments of the present invention, the sealing gasket is adapted to the shape of the top end face of the exhaust column, and the two can form an end face sealing structure for blocking gas flow.

Detailed Implementation

[0017] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0018] like Figures 1 to 3 As shown, an automatic exhaust connection device includes an upper cover (1), a housing (2), an exhaust cap 3, a float 4, an inner sealing ring 5, an outer sealing ring 6, a support rod 7, a support seat 8, a sealing gasket 9, a compression spring 10, and an exhaust column 11. The upper cover 1 is fixedly connected to the housing 2. The float 4, the support seat 8, the compression spring 10, the support rod 7, the sealing gasket 9, and the exhaust column 11 are all housed inside the housing 2. The exhaust cap 3 covers the top of the upper cover 1. The inner sealing ring 5 is assembled on the outside of the exhaust column 11. The outer sealing ring 6 is installed on the outer connection part of the housing 2.

[0019] In this embodiment, through the reasonable layout and assembly of various parts, an automatic exhaust system with complete structure and coordinated functions is formed. The top cover 1 and the shell 2 provide a stable installation base, and the core components such as the float 4 and the support rod 7 are precisely matched. The inner sealing ring 5 and the outer sealing ring 6 provide double sealing protection, effectively realizing the dual functions of exhaust and leakage prevention, and adapting to the usage requirements of automotive cooling pipes.

[0020] The top cover 1 and the shell 2 are fixedly connected by laser welding to form a closed outer shell cavity.

[0021] In this embodiment, the laser welding process makes the connection between the top cover 1 and the shell 2 stronger and better sealed, preventing the cooling medium from leaking from the connection. The closed shell cavity provides a stable working environment for internal parts such as the float 4 and support rod 7, preventing external impurities from entering and affecting the operating accuracy of the device.

[0022] The inner sealing ring 5 and the exhaust column 11 are assembled to form an exhaust column sub-assembly, and the inner sealing ring 5 is tightly fitted to the outer wall of the exhaust column 11.

[0023] In this embodiment, the tight fit between the inner sealing ring 5 and the exhaust column 11 enhances the sealing performance of the exhaust column sub-assembly, effectively preventing the cooling medium from leaking from the gap between the exhaust column 11 and other components, ensuring that the exhaust channel is only open under specific conditions, and improving the sealing reliability of the device.

[0024] The support rod 7 and the sealing gasket 9 are assembled to form a support sub-rod assembly, and the sealing gasket 9 is fixedly installed at one end of the support rod 7.

[0025] In this embodiment, the integrated design of the support rod assembly makes the sealing gasket 9 more synchronized and precise with the rotation of the support rod 7, ensuring that the sealing gasket 9 can form a seal or break the seal with the exhaust column 11 in a timely manner, improving the response speed of the exhaust and sealing switching, and ensuring the working efficiency of the device.

[0026] The support base 8 is fixed to the bottom wall inside the housing 2, and the compression spring 10 is sleeved between the support base 8 and the support rod 7 to provide the restoring elastic force for the support rod 7.

[0027] In this embodiment, the support base 8 provides a stable mounting support point for the compression spring 10 and the support rod 7. The elastic force of the compression spring 10 enables the support rod 7 to quickly drive the sealing gasket 9 back to the sealing position when the float 4 is reset, ensuring that the sealing structure closes in time and avoiding excessive leakage of cooling medium.

[0028] Buoy 4 is movably connected above support base 8. Buoy 4 and support rod 7 are in transmission cooperation. The lifting and lowering movement of buoy 4 can drive support rod 7 to rotate around the connection point.

[0029] In this embodiment, the buoy 4 can accurately sense changes in the liquid level in the pipeline. Through transmission cooperation with the support rod 7, the liquid level signal is converted into mechanical rotation action, realizing the automatic opening and closing of the sealing structure without manual intervention, thus improving the automation level and response sensitivity of the device.

[0030] The sealing gasket 9 is adapted to the top end face shape of the exhaust column 11, and the two can form an end face sealing structure for blocking the flow of gas.

[0031] In this embodiment, the shape-fitting sealing gasket 9 and the exhaust column 11 can form a tight end face seal, which blocks the flow of gas and cooling medium to the greatest extent, ensuring the sealing performance of the device in the non-exhaust state, while in the exhaust state, it can accurately disengage from the seal to ensure smooth gas discharge.

[0032] The exhaust cap 3 has a through vent hole, which is used to guide the gas discharged from the device to the atmosphere.

[0033] In this embodiment, the vent hole of the exhaust cap 3 provides a stable outlet channel for the discharged gas, preventing the gas from accumulating at the top of the device and causing the pressure to be unable to be released. At the same time, it can prevent external dust and impurities from entering the device through the exhaust port, protecting internal components such as the float 4 and the sealing gasket 9 from contamination.

[0034] The exhaust column 11 is vertically positioned at the center of the device, with its top end corresponding to the sealing gasket 9, forming a sealed fit structure for the gas exhaust channel.

[0035] In this embodiment, the vertical arrangement of the center of the exhaust column 11 allows the gas to naturally converge near the exhaust channel, improving exhaust efficiency. The corresponding arrangement with the sealing gasket 9 ensures the accuracy of the sealing fit, guarantees the blocking effect during sealing and the unobstructed channel during exhaust, and further optimizes the exhaust and sealing performance of the device.
