Description

Inflator pump with pressure release protection architecture Technical Field The utility model relates to the technical field of air pumps, in particular to an air pump with a pressure relief protection structure. Background In the application of modern inflatable devices, air pumps are widely used as core components in a variety of contexts, such as massage devices, medical appliances, and inflatable devices. However, most air pumps on the market currently have a certain potential safety hazard in design, especially in the case of lacking a pressure relief component, if the control logic of an Electronic Control Unit (ECU) of the whole machine fails, the air pressure in the air inflation chamber may be too high, so that the risk of the massage air bag or other inflatable objects being ruptured may be caused. This situation may not only affect the normal use of the device, but may also pose a potential security threat to the user. In the prior art, although some air pumps attempt to alleviate this problem by adding electronic protection measures, the electronic components themselves may have a risk of failure or failure, and accidents caused by too high air pressure cannot be completely avoided. Therefore, there is a need for a design that provides additional safety at the mechanical level to ensure that in extreme cases too high an air pressure can be effectively released, thereby protecting the safety of the equipment and the user. The invention aims to solve the problems, and provides more reliable safety guarantee for the inflator pump by introducing a mechanical pressure relief protection structure, and simultaneously improves the overall stability and the service life of the equipment. Disclosure of utility model The utility model aims to provide an inflator pump with a pressure relief protection structure, which overcomes the defects in the prior art. In order to achieve the above object, the present utility model provides the following technical solutions: An inflator pump with a pressure relief protection structure comprises a pump body, an upper cover structure, a buckling groove, a safety buckle design and a pressure relief protection structure. Wherein: The pump body is a core component of the inflator pump, an upper cover is arranged at the top of the pump body in a sealing and fixing mode, and the upper cover and the top of the pump body are matched to form a sealed inflation cavity for storing and outputting gas. The bottom of the upper cover is provided with an air charging nozzle communicated with the upper cover, and the air charging nozzle is used for charging air into a target acting object. Further, the volume of the inflation chamber is determined by the structural dimensions of the pump body and the upper cover so as to meet the gas demand of a specific application scene. Particularly, in order to prevent the upper cover from being severely expanded and popped up when the internal air pressure is abnormally increased, the inflator pump is provided with corresponding buckling grooves on the top surface of the upper cover and the bottom of the pump body extending outwards. After the upper cover is fixed with the pump body, a plurality of safety buckles are additionally arranged, and two ends of each safety buckle are respectively abutted with buckling grooves corresponding to the upper cover and the pump body. The design of the safety catch enhances the bonding strength between the upper cover and the pump body in a physical connection mode, thereby avoiding potential safety hazards caused by overlarge air pressure. Further, the pressure relief protection structure is one of the core innovation points of the utility model, and the specific implementation mode is as follows: The pressure relief protection structure comprises a pressure relief opening, a pressure relief nut, a pressure relief silencing sponge, a pressure relief spring and a pressure relief sealing plug. The pressure relief opening is positioned on the top surface of the upper cover and is of an upward extending integrated structure, and the inner wall of the pressure relief opening is provided with an internal thread. The pressure relief nut is of a middle-through structure, is fixed on the inner wall of the pressure relief opening through threaded connection, and is fixedly connected with the pressure relief silencing sponge of the porous structure on the inner wall of the pressure relief nut. The effect of pressure release amortization sponge is through the noise that produces when its porous structure reduces the gas circulation to optimize user experience. Specifically, the pressure release spring is arranged at the bottom of the pressure release nut, and two ends of the pressure release spring are respectively abutted against the top of the pressure release sealing plug and the bottom of the pressure release nut. Under the normal working state, the pressure release sealing plug tightly props against the gas containing
