Description

Technical Field

[0001] The utility model belongs to the field of airtight detection, and more specifically relates to an automatic airtight detection device. Background Technique

[0002] The toilet filter is an important component in the intelligent toilet, which is used to filter impurities in water, ensure the water quality, and extend the service life of the product.

[0003] When the toilet filter leaves the factory, the industry generally fills the toilet filter with gas manually and then immerses it in water to detect whether there are bubbles emerging, so as to judge whether the toilet filter is qualified. This detection method requires the filter to be immersed in water for a period of time and observed and detected, which is time-consuming and not applicable to the situation that requires rapid and accurate detection, with low efficiency. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide an automatic airtight detection device, which has the advantage of improving the detection efficiency of the product airtightness.

[0008] The advantages of this solution are at least as follows: When it is necessary to detect the airtightness of the toilet filter, the toilet filter is placed into the tooling fixture, the fixing component and the ventilation mechanism are started to fix the toilet filter on the fixture, then the gas blocking mechanism is started to block the water outlet of the toilet filter, the solenoid valve assembly is started to inflate the toilet filter, after inflation, the toilet filter is kept pressurized and tested. At this time, the pressure sensor will detect the airtightness inside the toilet filter. If the toilet filter is qualified, the alarm will sound; on the contrary, if it is unqualified, the alarm will also sound, so as to judge whether the airtightness of the toilet filter meets the standard. Finally, the air is released through the air release valve to complete the airtightness test.

[0009] The present utility model is further configured as follows: The solenoid valve assembly includes a manifold plate, a pressure maintaining valve, a pressure releasing valve, and an intake valve.
