Description

Technical Field

[0001] The utility model relates to an inflation device, in particular to an intelligent tire inflation device. Background Art

[0002] A tire inflator is a special device for inflating a tire. At present, the structure of the tire inflator on the market mainly includes an air pump, and the air outlet end of the air pump is connected to the inflation head through an air pipe. When inflating, connect the inflation head to the inflation port on the tire, then turn on the switch on the air pump to inflate the tire. Because the air pressure in the tire is unknown, it is necessary to stop inflating several times during the inflation process to check the tire pressure on the inflation head (the pressure gauge cannot correctly display the pressure when inflating, and the tire pressure can only be detected normally when inflating is stopped). If the tire pressure is too low, continue to inflate, and if the tire pressure is too high, deflate it. Keep checking the tire pressure value, and keep squatting to inflate, which is very inconvenient for personnel to operate; in addition, since the above-mentioned inflation operation is very cumbersome, the air pump has already reached the highest pressure and activated the high-voltage power-off switch. The high-pressure switch protection pressure value of a conventional air pump is about 6KGF / cm, and the air pressure drops to 5.9kgf, the air pump is started again, which causes the air pump to start and stop repeatedly under high pressure, which is very harmful to the air pump and greatly reduces the service life of the air pump. Utility Model Content

[0003] In view of the shortcomings of the background technology, the technical problem to be solved by the present invention is to provide an intelligent tire inflation device for solving the above-mentioned problems.

[0004] To this end, the utility model is implemented by adopting the following scheme:

[0005] An intelligent tire inflation device has an air pump, characterized in that: the air outlet end of the air pump is connected to the air inlet end of an air tank through a first air pipe, the air outlet end of the air tank is connected to an inflation head through a second air pipe, an air pressure sensor is arranged in the air tank, the air pressure sensor is connected to a controller signal, and the controller can compare the information fed back by the air pressure sensor with the set air pressure value, thereby controlling the start and stop of the air pump.

[0006] A control panel connected to the controller signal is arranged outside the gas storage tank.

[0007] A relay is connected in series to the wiring circuit of the air pump, and the controller can control the on and off of the relay.

[0008] The relay is connected to an external switch, and the external switch can also control the on and off of the relay.

[0009] An intelligent tire inflation device of the above technical solution is provided with an air tank to receive the high-pressure gas of the air pump, and then the high-pressure gas in the air tank is used for inflation, and an air pressure sensor is provided in the air tank to detect the pressure of the air tank in real time, and the inflation situation is analyzed by the detected air pressure and the start and stop of the air pump are automatically controlled. There is no need to frequently stop the inflation manually to detect the tire pressure, which effectively simplifies the inflation operation, avoids the frequent start and stop of the air pump, and improves the working stability and service life of the air pump. It is a high-precision intelligent tire inflation device integrating pressure collection, display and control. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The utility model has the following drawings:

[0011] Figure 1 It is a schematic diagram of the structure of the utility model;

[0012] Figure 2 It is a cross-sectional view of the gas storage tank of the utility model. DETAILED DESCRIPTION

[0013] As shown in the figure, the utility model discloses an intelligent tire inflation device, which has an air pump 4, the outlet end of the air pump 4 is connected to the air inlet end of the air tank 7 through the first air pipe 5, the outlet end of the air tank 7 is connected to the inflation head 9 through the second air pipe 8, and the air pressure sensor 10 is arranged in the air tank 7. Of course, the air pressure sensor 10 can also be arranged on the pipeline connected to the air tank 7 or on the air pump 4, as long as the air pressure in the air tank 7 is detected; the air pressure sensor 10 is connected to the controller signal, and the controller can compare the information fed back by the air pressure sensor 10 with the set air pressure value, and then control the start and stop of the air pump 4. In addition, a control panel 6 connected to the controller signal is arranged outside the air tank 7, which can control the start and stop of the inflation device, display the real-time pressure, and facilitate the setting of the required inflation pressure. In this embodiment, a relay 2 is connected in series to the wiring circuit of the air pump 4, and the controller can control the on and off of the relay 2, and the wiring circuit is connected to the battery. The relay 2 is connected to the external switch 3, and the external switch 3 can also control the on and off of the relay 2. Of course, in addition to using a relay structure, a switch circuit can also be used to control the start and stop of the air pump 4.

[0014] The working principle of the utility model is: when it is necessary to inflate the tire, connect the inflation head 9 with the inflation port of the tire, control the air pump 4 to start, and inject high-pressure gas into the air tank 7. The high-pressure gas will be injected into the tire through the inflation head 9. When the pressure in the tire reaches the set value, as the air pump continues to inject high-pressure gas into the air tank 7, the pressure in the air tank 7 rises to the set value of the controller. At this time, the controller receives the pressure information and controls the air pump 4 to shut down, thereby completing the tire inflation operation; in addition, the high stop and low start of the air pump can also be set, that is, the controller pressure is set to shut down the high pressure and start the low pressure, and the air pump 4 supplies air to the air tank 7. When the air pressure reaches the high pressure shutdown, the air pump 4 stops working. When the pressure drops to the starting low pressure, the air pump starts working again, and the pressure is pumped back to the high pressure shutdown and then stops. It can effectively protect the air pump and greatly improve the service life of the air pump.

[0015] The structure of the utility model provides an air tank to receive the high-pressure gas of the air pump, and then uses the high-pressure gas in the air tank for inflation, and provides an air pressure sensor in the air tank to detect the pressure of the air tank in real time, and analyzes the inflation situation through the detected air pressure and automatically controls the start and stop of the air pump. There is no need to manually stop the inflation frequently to detect the tire pressure, which effectively simplifies the inflation operation, avoids frequent start and stop of the air pump, and improves the working stability and service life of the air pump.
