Description

Inflating device for automatic pressure detecting inflation and pressure relief

This creation is about an automatic pressure detection inflation and pressure relief inflation device, in particular, an inflation line is provided with a pressure sensor at a position adjacent to the inflation object, and the inflation line is provided with a gas transmission channel and a first signal transmission line. The inflating pipeline is connected to the inflator by the gas transmission channel, and the first signal transmission line is electrically connected to the pressure sensor and the control circuit provided by the inflator, so that the pressure sensor and the control circuit are electrically connected; The position of the sensor is adjacent (close) to the inflated object, so that the air pressure data detected by the pressure sensor is closer to the internal pressure of the inflated object, so as to effectively reduce the actual air pressure of the inflated object and the output pressure of the inflator. Therefore, when the internal pressure of the approached inflated object is detected by the pressure sensor to be the same as the preset value of inflation of the inflator, the inflator will stop operating. In addition, a pressure relief device is provided through the inflator to make When the pressure sensor detects that the internal pressure of the object to be inflated is greater than the inflation preset value, So that the pressure relief device to relieve pressure starts to enabling won the case seeking perfect their automatic detection of pressure inflatable cum discouraged effect.

According to the press, air compressors or small inflators are mainly used in pneumatic tools, vehicle tires or a variety of inflators, etc., as the source of pressure gas output or power output source; therefore, in the automotive field or DIY do it yourself In the field of work, the role of air compressor or inflator has long been established Necessary pressure gas supply equipment for car on-board and work place and general home repair.

As for the working principle of the inflator, the internal motor directly drives the crankshaft to rotate the crankshaft, and then drives the connecting rod to cause the piston to reciprocate up and down, thereby causing the cylinder volume to change. The volume of the cylinder is reduced, and the compressed air is output by a hose through a check valve (check valve) through a hose to inflate an object.

In addition, in order to prevent the inflator from inflating the object excessively, causing the inflated object to burst or be damaged, it is known that the inflator is provided with a pressure gauge and a pressure detector, so that the inflator will charge an inflated object according to a preset pressure. (Such as: tires) for inflation. During the inflation process, when the pressure detector detects that the gas pressure output by the inflator reaches a predetermined pressure (ie, the number of inflation pounds), the inflator will automatically stop inflating to avoid being inflated. Objects are over-inflated with excessive pressure.

However, for an inflator with the ability to detect pressure, the equipped pressure detector is installed at the outlet of the inflator; in fact, the pressure value at the outlet of the inflator must be greater than The pressure of an inflated object (such as a tire); therefore, when the pressure detector detects that the gas pressure output by the inflator reaches a predetermined pressure (ie, the number of pumped pounds), the pressure detected by the pressure detector at this time The pressure is the pressure value at the outlet end of the inflator, not the actual pressure value of the inflated object (such as a tire). This situation is bound to result in the actual pressure of the inflated object and the pressure gauge after the completion of the inflated object. The set pressure will inevitably have a relative degree of difference, which will cause the inflated object and the actual inflation pressure demand value to be insufficient, and the inflated object will be used when the pressure demand value is insufficient, which will affect the use efficiency and safety of the inflated object.

Therefore, how to develop a precise, reliable and fully able Air pressure, the design of automatic inflation and pressure relief operations, is the main problem to be solved for this creation.

In order to solve the problems and shortcomings of the above-mentioned conventional technologies, this creation discloses an inflating device for automatic pressure detection inflation and pressure relief, which includes an inflator and at least one inflation line: the inflator is provided with an air outlet, and the internal of the inflator is provided with There is a control circuit, the control circuit can set an inflation preset value; the inflation pipeline has an air transmission channel and a first signal transmission line, one end of the gas transmission channel is provided with an air inlet end and the other end is provided with an inflation end, air inlet The air end is connected to the air outlet of the inflator. The air end is combined with an air nozzle, and a pressure sensor is provided adjacent to the air line of the air line. The first signal transmission line is electrically connected to the pressure sensor and the control circuit of the inflator. The pressure sensor and the control circuit are electrically connected, so that the data detected by the pressure sensor is transmitted to the control circuit via the first signal transmission line, and the control circuit determines whether the data detected by the pressure sensor reaches the preset value of inflation, and then the The control circuit performs stop or start control of the inflator.

The creative technical feature is that the inflation line is provided with a pressure sensor at the position adjacent to the inflated object. The inflation line is provided with an air transmission channel and a first signal transmission line at the same time, so that the inflation line is connected to the inflator by the air transmission channel. Then, the first signal transmission line is electrically connected to the pressure sensor and the control circuit provided by the inflator, so that the pressure sensor and the control circuit are electrically connected; therefore, the position set by the pressure sensor is adjacent to the inflated object ( (Close to each other), so that the air pressure value detected by the pressure sensor can more accurately approach the actual internal pressure of the inflated object, and effectively reduce the error between the actual air pressure of the inflated object and the output air pressure of the inflator. If the internal pressure of the approached inflated object is detected to be the same as the preset value of the inflator through the pressure sensor, the inflator will stop operating, and the automatic inflation operation will be completed accurately and reliably according to the air pressure required by the inflated object.

A technical feature of this creation is that the inflator is further provided with a pressure relief device at the air outlet port.
