Description

Technical Field

[0001] The utility model relates to the technical field related to air conditioners, in particular to a combined sealing cap structure. Background Art

[0002] The air conditioner evaporator cap is a crucial component in air conditioning systems. It primarily seals the evaporator's interfaces and serves as a warning system. Under normal circumstances, it prevents refrigerant leaks and maintains a stable pressure within the evaporator. However, if the evaporator's internal pressure fluctuates abnormally, such as excessive pressure or a minor leak, the cap may generate a warning signal to maintenance personnel or the user. Existing cap structures often use color-coding to read the warning signal, making it difficult to identify the color of the warning signal during observation and resulting in poor performance. Utility Model Content

[0008] The sealing cap structure includes a nut shell, a sealing gasket and a warning slide column, wherein the nut shell is connected to the connecting pipe of the air-conditioning evaporator in the form of a threaded connection, which plays a role in sealing the air-conditioning evaporator. The provided sealing gasket is installed and clamped inside the nut shell. At the same time, a sliding groove is provided on the outer top of the sealing gasket, and the sliding groove is used to install the warning slide column. At the same time, a compression chamber is provided on the inner top of the sealing gasket, and the compression chamber is connected to the sliding groove.

When observing the warning observation chamber from the outside, the warning color block cannot be observed, confirming that the pressure of the air-conditioning evaporator is normal. When the air-conditioning evaporator leaks and the pressure is abnormal, the warning slide moves downward, and the warning end of the warning slide moves downward, leaking the warning color block in the warning observation chamber, so that the warning color block can be observed from the outside, confirming that the pressure of the air-conditioning evaporator is abnormal and a leakage signal has occurred. This structure has a good observation effect, the observation signal obtained is accurate, and the use effect is good.

[0035] The working principle of this utility model is as follows: Figure 1-3 As shown, the sealing structure comprises a nut housing 1, a sealing block 3, and a warning slide 4. The nut housing 1 is threadedly connected to the connecting pipe of the air conditioner evaporator, sealing the air conditioner evaporator. The sealing block 3 is mounted and snapped into place within the nut housing 1. A sliding groove 30 is provided on the outer top of the sealing block 3 for receiving the warning slide 4. A compression chamber 31 is provided on the inner top of the sealing block 3, communicating with the sliding groove 30. The warning slide 4 has an upper warning end and a lower connecting end, with the connecting end of the warning slide 4 inserted into the sliding groove 30. A warning observation chamber 2 is provided at the top of the nut housing 1. This cylindrical structure has a warning color block 20 mounted on its inner wall. This warning color block 20 is a different color than the warning slide 4. The warning end of the warning slide 4 is inserted into the warning observation chamber 2. When the pressure of the air-conditioning evaporator is normal, the compression chamber 31 is compressed. At the same time, the gas in the compression chamber 31 pushes the warning slide 4 upward, so that the warning end of the warning slide 4 blocks the warning color block 20. When observing the warning observation chamber 2 from the outside, the warning color block 20 cannot be observed, confirming that the pressure of the air-conditioning evaporator is normal. When the air-conditioning evaporator leaks and the pressure is abnormal, the warning slide 4 moves downward, and the warning end of the warning slide 4 moves downward, leaking the warning color block 20 in the warning observation chamber 2, so that the warning color block 20 can be observed from the outside, confirming that the pressure of the air-conditioning evaporator is abnormal and a leakage signal has occurred. This structure has a good observation effect, the observation signal obtained is accurate, and the use effect is good.

[0036] Among them, the warning observation cavity 2 is a transparent cavity, and a boss structure is provided on the top of the nut shell 1.

The warning color block 20 is embedded in the card slot 21, and the color of the warning color block 20 is different from the color of the warning slide column 4. The color difference between the two can ensure the accuracy of the observation signal and improve the use effect.

[0038] Among them, the shape of the sealing gasket block 3 is conical, and the side wall of the sealing gasket block 3 is a stepped structure. Through the setting of the stepped structure, it is possible to match the inner wall of the nut shell 1, ensuring the stability of the installation, thereby improving its sealing effect and improving the use effect.

[0039] Among them, two guide grooves 32 are set on the top of the sealing gasket 3, and the guide grooves 32 are distributed on both sides of the sliding groove 30.

The push rod 40 is inserted into the sliding groove 30, and the guide rod 41 is inserted into the guide groove 32. The guide rod 41 cooperates with the guide groove 32 to realize the guiding effect of the warning slide 4, ensuring the stability of the push rod 40 sliding in the sliding groove 30, and then ensuring the movement stability of the warning slide 4, improving its use effect, and ensuring the accuracy of the observation signal obtained.

The push piece 42 contacts the stop groove 33 to complete the stopping effect, ensuring that the early warning slide can block the early warning color block, and then drive the push rod 40 to move upward, and then complete the early warning slide 4 to slide into the early warning observation chamber 2 to block the early warning color block 20. When the air-conditioning evaporator leaks, the compressed compression chamber 31 is restored, and the early warning slide 4 moves downward to expose the early warning color block 20, realizing early warning observation, improving its use effect, and ensuring the accuracy of the observation signal obtained.
