In addition, in the following description of the present invention, detailed descriptions of known related technologies may be omitted to avoid unnecessarily obscuring the subject matter of the present invention.

Referring to FIG. 1 to FIG. 5, the multifunctional air compressor capable of extracting gas according to the present invention includes: an air storage barrel 10 forming an accommodating space for storing gas, and an axial direction of a barrel body of the air storage barrel 10 and A plurality of air valves 11 are provided in the radial direction for air outlet or air intake; an air pressure switch 30 is used to detect and respond to the gas pressure in the gas storage tank 10; and a pressure device 20 having a filter unit 21. The gas outside the gas storage barrel 10 enters the pressure device 20 through the filtering unit 21, and the gas pressurized by the pressure device 20 is delivered to the gas storage barrel 10 through the air pressure switch 30 through the gas pipe 22.

The gas storage barrel 10 can be in the shape of an elongated barrel, and its axial direction is parallel to the ground. The bottom of the gas storage barrel 10 has a stand for supporting. Therefore, the gas storage barrel 10 can be stably placed on the ground. The pressurizing device 20 and the air pressure switch 30 are disposed above the air storage barrel 10 and are connected by an air pipe 22. In addition, when not in use, the entire air compressor can be dumped horizontally to facilitate storage.

The air valve 11 may include a first air valve 111 and a plurality of second air valves 112. The first gas valve 111 may be disposed in the axial direction of the barrel body of the gas storage barrel 10 to discharge or intake air in the axial direction. Since the wall surface of the gas storage barrel 10 in the axial direction is thicker and stronger, the first The air valve 111 may have a larger aperture than the second air valve 112 to provide a larger amount of air output, thereby obtaining a larger power. In addition, the second gas valve 112 may be disposed in a radial direction of the barrel body of the gas storage tank 10 to discharge or intake air in the radial direction, and the second gas valve 112 may have a smaller aperture than the first gas valve 111 To provide a choice of different aperture sizes.

An electric wire 34 may be provided at the air pressure switch 30 to connect a power source to provide power required for the operation of the air compressor. According to the requirements of use, an appropriate electric wire 34 may be provided to connect the power source. The electric wire 34 may be a battery wire for connecting a car battery. When going out, if the car breaks down and needs temporary repair or other power needs, it can be directly connected to the car's own battery to provide air compressor power. Alternatively, the electric wire 34 can also be a plug connected to a general household outlet, and is provided with a rectifier (not shown in the figure), which is connected to the household's AC power and can be used to repair the car at home. In addition, a battery (not shown) can also be provided, which can store power itself without connecting to other power sources, so the air compressor can also be used where there is no other power source.

The first air valve 111 and the second air valve 112 can be directly connected to the tire for inflation, or can be selectively connected with different devices according to needs to provide different functions. For example: connect the tire changing tool, you can separate the wheel frame and the tire; connect the top crane, you can use the air pressure to lift the car body; or, connect the water tank and the fan, which can generate a powerful water column to wash the car, etc. widely.

In addition, since the air compressor of the present invention has more than one gas valve 11, according to actual use requirements, only one gas valve 11 can be used at a time, one device can be connected to be used alone, or a plurality of gas valves 11 can be connected at the same time. The devices are used simultaneously. In addition, the high pressure air passing through the gas valve 11 will cause a strong impulse, which may damage the connection of the gas valve 11, but because more than one gas valve 11 is provided, if one of the gas valves 11 is damaged, it is not necessary to Send it for repair immediately, you can replace it with other air valve 11 and continue to use it.

For example, the high-pressure gas in exhaust tires actually has use value, but most of the time, it can only be allowed to evacuate high-pressure gas from the waste tires and cannot be recovered. It is a pity. By using the air compressor of the present invention, high-pressure gas such as exhaust tires can be input into the air storage barrel 10 for recycling and reuse, avoiding waste. Before the pressurization device 20 is used to pressurize, the air storage barrel 10 is in a low pressure state. At this time, the waste tire is connected to the air valve 11, and the air pressure in the exhaust tire is higher than that in the air storage barrel 10. The air can flow from the waste tire to the air tank 10, and then fill the gas into another tire that needs to be inflated, or use it in other devices. In this way, the workload of the pressurizing device 20 can be reduced, thereby reducing power consumption. In addition, in accordance with the actually connected aperture, the first air valve 111 or the second air valve 112 is selected for air intake, and a plurality of second air valves 112 can be connected for air intake at the same time to save time.

Referring to FIGS. 4 and 5, the air compressor may further include a connecting pipe 42. Two ends of the air compressor are respectively provided with a joint 41. One end of the joint 41 is connected to one of the gas valves 11, and the other end of the joint 41 is connected to a different function. Device to produce different functions. The joint 41 has a circular tube shape, and one end of the joint 41 has two fixing members 411 on corresponding sides, and the two fixing members 411 can be moved in the direction of the arrow shown in FIG. 5. When in use, first pull the two fixing pieces 411 to be substantially straight. When the two fixing pieces 411 are substantially straight, the two fixing pieces 411 are not pressed to the inside of the joint 41. At this time, the air outlet valve 11 can be Or other devices are inserted into the joint 41, and then the two fixing pieces 411 are pressed down to make them close to the periphery of the circular tube of the joint 41, which is basically two parallel lines (as shown in FIG. 4). The component in the joint 41 presses and clamps the element in the joint 41 to achieve a fixed function. When it needs to be disassembled, pull the two fixing members 411 upwards so that they are substantially in line. At this time, the two fixing members 411 are not pressed into the inside of the joint 41 and loosen the clamping of the components in the joint 41, so The joint 41 can be detached from the air valve 11 or other devices. The connecting pipe 42 can also be connected to the gas valve 11 or other devices using other connection methods, but the commonly used rotary tenon requires the entire rotating connecting pipe 42 to be fixed or disassembled, especially for the large-diameter first gas valve 111. The connecting pipe 42 is relatively thick and heavy, and it is not easy to rotate the whole. Therefore, the use of the joint 41 without moving the entire connecting pipe 42 saves energy and is beneficial to everyone.

The air pressure switch 30 can be used for regulating and controlling pressure, and is provided with a switch 32 for switching on and off. The air pressure switch 30 may include a safety valve 33. If the pressure device 20 continues to pressurize the air, and the pressure in the air storage tank 10 is too high, it is likely to cause danger. When the pressure exceeds a safe value, the safety valve 33 automatically opens, venting gas, reducing the pressure below a safe value to avoid danger. The air pressure switch 30 may further include a pressure gauge 31 for a user to read the pressure value. In addition, the air pressure switch 30 may include a control system (not shown in the figure). The user sets a preset value in advance according to the required pressure. When the pressure device 20 pressurizes the air, the air pressure switch 30 detects The gas pressure, if it has not reached the preset value, the pressurizing device 20 continues to pressurize the gas, and the gas in the gas storage tank 10 that is not high enough can be returned to the pressurizing device 20 to continue pressurizing until the gas pressure reaches the preset value Value, the operation of the pressurizing device 20 is stopped.

The lower part of the gas storage tank 10 may have a drain valve 12. After the air is pressurized by the pressurizing device 20, since the boiling point of the high-pressure gas is low, the water vapor in the air is pressurized by the pressurizing device 20 and becomes water, which is deposited in Gas storage barrel 10. In addition to water, some impurities will also melt in the water and deposit in the gas storage tank 10. If left untreated, it will accumulate for a long time, which will affect the air efficiency of the air compressor. Therefore, the drain valve 12 needs to be opened regularly to allow the water to automatically flow out, and the water in the air storage bucket 10 and impurities dissolved in the water are excluded.

The filter unit 21 may include a filter screen 211, an air filter cover 212, and a screw 213. If the air entering the pressurizing device 20 contains many impurities, during the operation of the pressurizing device 20, it will rub against the impurities in the air. Over a long period of time, it will cause damage to the pressurizing device 20 and increase maintenance costs. Therefore, the air entering the pressurizing device 20 needs to pass through the filter 211 and then enter the pressurizing device 20. The filter 211 can filter most of the impurities in the air, avoiding the impurities in the air and the pressurizing device 20 to rub the pressurizing device 20 damage. In addition, after the pressurization is completed, the air filter cover 212 is used to cover the filter screen 211 and fixed with screws 213 to prevent the air compressor from communicating with the outside and causing the pressurized air to leak. Wherein, one end of the screw head of the screw 213 may be provided with two strip-shaped protrusions, which are respectively disposed on two opposite sides of the screw head of the screw 213, that is, a general butterfly screw head. Observed in the axial direction of the screw 213, the two strip-shaped protrusions are located on a straight line, and extend obliquely from one end of the screw head of the screw 213. When viewed in a direction parallel to the two strip-shaped protrusions, the entire screw 213 is Y type. With this protrusion, the screw 213 can be easily rotated with bare hands to fix or open the air filter cover 212 without the aid of a tool such as a screwdriver.

The pressurizing device 20 may be a reciprocating piston compressor, but is not limited to this, and may also be another device capable of pressurizing a gas.

The capacity of the gas storage tank 10 can be adjusted according to the horsepower of the pressurizing device 20, and a larger capacity gas storage tank 10 can store more high-pressure gas. If it is for carrying, a smaller capacity gas storage can be selected. Bucket 10.

As is apparent from the above description, the air compressor according to the present invention has the following advantages.

The plurality of gas valves 11 provided on the barrel of the gas storage barrel 10 can be connected and used with multiple devices at the same time, and if one of the gas valves 11 is damaged, the other gas valve 11 can be replaced immediately without the need for immediate repair. In addition, the gas valve 11 provided on the barrel of the gas storage tank 10 may have a larger hole diameter than that of a general air compressor, providing a larger gas output and further providing greater power. In addition, the air compressor of the present invention can not only discharge high-pressure gas, but also take in air from the gas valve 11 of the barrel of the gas storage tank 10 to recover and reuse external high-pressure gas.

In addition, the joint 41 of the connecting pipe 42 of the present invention is fixed and disassembled by pulling the fixing member 411. Therefore, it is only necessary to apply force to the fixing member 411, and it is not necessary to rotate the entire connection as when using a common rotary tenon. The tube 42 requires less force, so it can save energy, so everyone can use it, and can easily replace various devices connected to the connection tube 42. For example, by connecting a tire replacement tool, the wheel frame can be separated from the tire. ; Connected to the top machine, you can use the pressure of the air to lift the car body; or, connected to the water tank and the fan, can generate a strong water column for car washing, etc., easy to use and versatile.
