Description

Technical Field

[0001] This utility model relates to an air compressor for generating high-pressure gas. Background Technology

[0002] In the prior art, such as Chinese utility model patent CN201821908218.7, published on September 20, 2019, an air compressor is disclosed, including a compressor head and an air tank. The compressor head includes a housing, a motor, a pump head, and a pressure switch. The housing has a battery pack receiving cavity for housing a battery pack. The pressure switch is located inside the housing. The motor and pump head are respectively horizontally placed inside the housing, and the motor and pump head are connected together to form two corner spaces on the left and right sides of the motor. The battery pack receiving cavity is located in one corner space on the left and right sides of the motor, and the pressure switch is located in the other corner space on the left and right sides of the motor. In the above solution, the pressure switch and pressure regulating component are installed in the housing through a manifold. During operation, the vibration generated by the motor is transmitted to the pressure switch and pressure regulating component, which also vibrate accordingly. Over a long period of operation, this can cause the pressure regulating component and pressure switch to shift or loosen. Utility Model Content

[0015] To clearly illustrate the solutions in this utility model, preferred embodiments are given below in conjunction with the accompanying drawings for detailed description. The following description is merely exemplary in nature and is not intended to limit the application or use of this disclosure. It should be understood that throughout the drawings, corresponding reference numerals denote the same or corresponding parts and features.

[0016] like Figures 1 to 3As shown, this utility model provides a compact and stable air compressor, including a housing 1, a pump body 2 installed in the housing 1, and a motor 3 driving the pump body 2. A pressure regulating component 4 is installed on the housing 1. The housing 1 includes a bottom shell 11 and an upper shell 12, with the upper shell 12 covering the bottom shell 11. A portion of the bottom shell 11 protrudes upward to form a protrusion 13, and a mounting position 14 is formed on the protrusion 13. The pressure regulating component 4 is installed on the mounting position 14. The motor 3 and pump body 2 in this utility model are mature existing technologies, and their specific structures and working principles will not be described in detail here. The main improvement of this utility model lies in the installation of the pressure regulating component 4. The protrusion 13 on the bottom shell 11 plays a role in improving strength and damping vibration. Directly installing the pressure regulating component 4 on the bottom shell 11 reduces connecting parts, eliminates the need for additional pipes or supports, and significantly reduces the risk of leakage. It enhances overall rigidity; the bottom shell serves as the main load-bearing structure, and the connection between the pressure regulating component and the bottom shell improves the system's vibration resistance. Especially under frequent start-stop or high-load conditions, it avoids valve displacement or loosening caused by vibration, ensuring pressure regulation accuracy. The vibration transmission path is shortened; the structure, through the vibration-damping design of the base shell, directly absorbs the operating vibration of the motor and the impact of airflow pulsation, reducing the vibration amplitude of the instrument components. Installation is convenient; the pressure regulating components are directly mounted on the base shell. Structural integration improves assembly efficiency, and modular maintenance (rapid repair) enhances overall performance.

[0017] See Figures 1 to 3 In the above embodiment of this utility model, the upper shell 12 is further provided with a hollow portion 121, through which the pressure regulating component 4 is exposed. The hollow portion 121 facilitates observation and operation. The pressure regulating component 4 of this utility model includes components such as a pressure gauge, a pressure regulating knob, and a connector, and there are multiple hollow portions 121, each corresponding to one of the aforementioned components.

[0018] See Figures 1 to 3 In the above embodiments of this utility model, the mounting position 14 further includes a plurality of protrusions, which are connected to the protrusion 13, and the pressure regulating component 4 is mounted on the protrusions. The pressure regulating component 4 is fixed to the top of the protrusions by screws. The protrusion 13 is integrally formed with the protrusions, and the mounting position 14 has higher strength.

[0019] See Figures 1 to 3 In the above embodiment of this utility model, a recess 15 is formed on the bottom surface of the bottom shell 11, and the motor 3 is mounted on the recess 15. The shape of the recess 15 is consistent with that of the motor 3, which facilitates the fixation of the motor 3 and makes it less prone to displacement.

[0020] See Figures 1 to 3In the above embodiment of this utility model, a mounting post 16 is further provided on the bottom shell 11, and a recessed hole 161 is formed on the top of the mounting post 16. A pressure switch 6 is installed at the recessed hole 161, and a switch hole 122 is formed on the upper shell 12, through which the pressure switch 6 passes. This utility model integrates the motor 3, the pressure regulating component 4, and the pressure switch 6 onto the bottom shell 11, improving assembly efficiency, modularizing subsequent maintenance, and enhancing overall performance.

[0021] See Figures 1 to 3 In the above embodiments provided by this utility model, the device further includes a gas storage tank 7, on which the housing 1 is mounted. The gas storage tank 7 is also provided with a handle, and wheels are provided at its bottom. The gas storage tank 7 is used to store high-pressure gas.
