[0011] Preferably, a groove is formed on the inner surface of the base, a fixing block is slidably connected inside the groove, and a spring is fixedly connected between the fixing block and the inner surface of the groove.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model provides a pressure balancing mechanism. When the vacuum liner leaks, the pressure on both sides of the slider is unbalanced, and the compression spring is extended, driving the slider, the round rod and the top plate to move. The top plate can thus resist the sensor. The sensor can transmit information to the user's mobile device. The user obtains the information and can replace the vacuum liner in time.
