AI Technical Summary
Existing mobile phone airtightness testing equipment is heavy, bulky, inconvenient to carry, and has poor clamp versatility, making it difficult to adapt to various mobile phone models and cumbersome to operate.
A mobile phone airtightness tester was designed, which uses a rigid rubber fixing plate and a soft rubber end panel. The end panel is deformed by pressing the SIM card slot of the mobile phone to achieve a seal. The test is carried out in combination with an air pump and an air pressure detector. It is compatible with a variety of mobile phone models and does not require the use of clamps.
It enables portable, simple, and fast air tightness testing, is compatible with various mobile phone models, and ensures the accuracy and convenience of testing.

Abstract
Claims
1. A mobile phone air tightness detector, characterized in that, The device includes a housing with a receiving cavity and an air pump, a three-way valve, an air pressure detector, and a main control circuit board respectively installed in the receiving cavity. It also includes a detection terminal installed on one side of the housing. The detection terminal includes a fixing plate made of hard plastic and an end panel made of soft plastic. The end panel covers and is connected to one side of the fixing plate. The fixing plate is installed on one side of the housing and the end panel extends out of the end face of the housing. The fixing plate is provided with a vent hole that penetrates the fixing plate and the end panel. The vent hole extends out of the side of the fixing plate away from the end panel to form a connection terminal. The output end of the air pump is connected to the first end of the three-way valve through the first connecting pipe, the air pressure detector is connected to the second end of the three-way valve through the second connecting pipe, and the connecting terminal is connected to the third end of the three-way valve through the third connecting pipe; the air pump and the air pressure detector are controlled by the main control circuit board.
2. The cell gas tightness tester of claim 1, wherein, On the side of the end panel near the fixing plate, a raised ring is provided around the vent hole; on the side of the fixing plate near the end panel, a groove is provided around the vent hole; the raised ring is located in the groove, and the size and shape of the groove and the raised ring are matched.
3. The apparatus of claim 1, wherein the apparatus further comprises a gas tightness detector. The outer sides of the connecting terminal and the air pressure detector are respectively fitted with clamps for fixing the third connecting pipe and the second connecting pipe.
4. The cell gas tightness tester of claim 1, wherein, The end panel has multiple protruding posts extending from the side near the fixing plate. The fixing plate has multiple through holes that match the protruding posts, and the protruding posts extend into the through holes and connect with the fixing plate.
5. The cell gas tightness tester of claim 4, wherein, A step is formed at the end of the through hole away from the end panel. A limiting block matching the step is provided at the end of the protruding post. The diameter of the through hole corresponding to the limiting block is smaller than the diameter of the through hole corresponding to the limiting block.
6. The cell gas tightness tester according to any one of claims 1-5, wherein, The fixing plate and the end are an integral structure.
7. The cell gas tightness tester of claim 1, wherein, The outer periphery of the fixing plate is provided with an inwardly recessed limiting groove, and one side of the housing is provided with a mounting hole. The limiting groove is engaged in the mounting hole and the end face of the mounting hole just abuts against the limiting groove.
8. The cell gas tightness tester of claim 1, wherein, It also includes a power supply for powering the system, which is installed within the housing cavity.
9. The cell gas tightness tester of claim 1, wherein, It also includes a panel installed on one side of the housing, the panel having a display screen and a pressing component, the main control circuit board having a start switch button, and the pressing component passing through the panel and the housing to abut against the start switch button.
10. The cell gas tightness tester of claim 1, wherein, The housing includes an upper housing and a lower housing, which engage with each other to form a receiving cavity.
