Abstract
The utility model discloses an automatic pressure detection device of an inflator, including an inflator and an inflation control module group: the first connector of the communication tube connected to the inflator is sequentially connected to the first pipeline and the air nozzle for inflating the object (such as a tire); the second connector of the communicating pipe connected to the inflator is sequentially connected to the valve core passage component, the control valve and the pressure sensor of the inflation control module, and the pressure sensor is electrically connected to the circuit board; moreover, the flow rate of the valve core passage device and the air nozzle is equal, so that the inflation control module can simulate the inflation flow rate of the object to be inflated; therefore, the air pressure output by the end of the regulating valve can be close to the same as the real air pressure in the inflated object, and when the air pressure value detected by the pressure sensor reaches the preset inflation value, the circuit board controls the inflator to stop operating, so that the inflator can indeed perform inflation operation according to the air pressure required by the inflated object.
Description
Technical Field
The invention relates to an automatic pressure detecting device of an inflator.
Background
The working principle of the inflator is that the internal motor directly drives the crankshaft to rotate, and further drives the connecting rod to make the piston move up and down reciprocally, so as to cause the volume change of the cylinder and complete the compression and discharge principle of the pressurized gas; therefore, during the whole compression stroke, the compressed air is output from the air nozzle through the hose via the check valve to inflate an object.
In addition, in order to avoid the situation that the object is excessively inflated by the inflator and the object to be inflated bursts or is damaged, the conventional inflator is provided with a pressure gauge and a pressure detector, so that the inflator can inflate an object to be inflated (such as a tire) according to a preset pressure, and when the pressure detector detects that the gas pressure output by the inflator reaches a preset air pressure (namely, inflation pounds), the inflator automatically stops the inflation operation, thereby avoiding the problem of excessive pressure caused by excessive inflation of the object to be inflated.
However, in the current inflator with the capability of detecting pressure, the pressure detector installed on the inflator body is installed at the position of the outlet; in addition, in the actual physical phenomenon, the pressure value of the air outlet end of the inflator is inevitably greater than the pressure of the object to be inflated (such as the tire) during the instant start and start operation; therefore, when the pressure detector detects that the gas pressure output by the inflator reaches the predetermined pressure (i.e. pound of inflation), the pressure detected by the pressure detector is actually only the pressure value at the air outlet end of the inflator, and is not the actual pressure value of the object to be inflated (e.g. tire), which will inevitably cause the difference between the actual pressure of the object to be inflated and the set pressure value of the pressure gauge after the operation of inflating the object to be inflated is completed, and further mislead the pressure value inflated by the object to be inflated to be the correct pressure value; the reason is that the object to be inflated is used under the condition of insufficient actual inflation pressure, which affects the use benefit and safety of the object to be inflated.
Therefore, the present inflator with pressure detection capability further installs a pressure detector at the inflation nozzle of the air outlet pipe, so as to achieve the purpose of truly detecting the actual pressure of the inflated object, and effectively reducing the error value between the actual air pressure of the inflated object and the output air pressure of the inflator; therefore, the large flow (high pressure) gas output from the inflator will concentrate on the physical back pressure phenomenon at the inflator, which results in the data detected by the pressure detector installed at the inflator being not the actual pressure of the object to be inflated, for example: if the data detected by the pressure detector of the inflating nozzle increases instantaneously, the control circuit of the inflator will erroneously determine that the inflated object has reached the preset inflating value, so that the control circuit will control the inflator to stop operation, and the actual air pressure of the inflated object will not reach the preset inflating value actually.
Therefore, it is a main subject to be solved by the present invention to provide a method for accurately inflating an object to be inflated.

Hereinafter, the embodiments will be described with reference to the accompanying drawings to explain the present general inventive concept.
Referring to the first to fourth figures, the present invention discloses an automatic inflator pressure detection device, which includes an inflator 1 and an inflation control module 2.
The inflator 1 (e.g. electric inflator) is provided with at least one gas outlet 11, the gas outlet 11 is connected with a communicating pipe 12, the communicating pipe 12 comprises a first joint 121 and a second joint 122, the first joint 121 is communicated with a first pipeline 13, the other end (end) of the first pipeline 13 is communicated with a gas nozzle 14, a gas nozzle core is arranged in the gas nozzle 14, and the gas nozzle 14 is used for connecting to a preset object 3 to be inflated (e.g. tyre, ball ∙ ∙ ∙, etc.). In addition, the communication tube 12 further includes a third connector 123, and a pressure display device (such as a mechanical pressure display device and an electronic digital pressure display device, which are not shown in the drawing) is connected to the third connector 123, and the pressure display device is not a desirable feature of the present application, so that the discussion will not be further elaborated.
The inflation control module 2 includes a valve core passage element 21, a control valve 22, a pressure sensor 23, and a circuit board 24 (e.g., control circuit).
The valve core passage member 21 is connected in communication with the second joint 122 of the communication pipe 12, for example: the valve core passage element 21 may be further sleeved with a connection joint 4, one end of the connection joint 4 is connected to a second pipeline 5, and the other end of the second pipeline 5 is connected to a second joint 122 to form a communication, so that the valve core passage element 21 can be communicated with the second joint 122, and the gas sent out through the second joint 122 can only pass through the valve core passage element 21; the air flow rate of the valve core passage component 21 is equal to the air flow rate of the air nozzle core installed in the air nozzle 14.
The regulating valve 22 is connected to the valve core passage member 21 in communication, for example: the control valve 22 can be connected to the other end of the connection joint 4, so that the control valve 22 can be connected to the valve core passage device 21, so that the gas sent out through the valve core passage device 21 can only pass through the control valve 22, and the control valve 22 is used to preset and limit the output flow of the gas, thereby presetting and adjusting the pressure of the gas output through the control valve 22.
The pressure sensor 23 is connected to the control valve 22, for example: the pressure sensor 23 may be connected to the other end (end) of the regulating valve 22, so that the pressure sensor 23 is used to detect the pressure value of the gas output by the regulating valve 22.
The circuit board 24 is electrically connected to the pressure sensor 23 and the electric motor preset in the inflator 1, and the circuit board 24 is used to receive the pressure information detected by the pressure sensor 23 and control the electric motor of the inflator 1 to start or close; in addition, the circuit board 24 can set the inflation pressure value for the object 3; in addition, the circuit board 24 can be electrically connected to a power module disposed on the inflator 1, so that the circuit board 24 can obtain power to provide the inflator 1 with operation.
This new form illustrates an embodiment: when the inflator 1 is activated, part of the gas output by the inflator 1 flows to the first joint 121, the first pipeline 13 and the air tap 14 of the communication pipe 12 in sequence to inflate the object 3 to be inflated (such as a tire); in addition, part of the gas output from the inflator 1 flows to the second joint 122 of the communication pipe 12, the second pipeline 5, the valve core passage element 21, the control valve 22 and the pressure sensor 23 in sequence, and the circuit board 24 is used to receive and interpret the pressure information detected by the pressure sensor 23 and control the electric motor of the inflator 1 to start or close.
Therefore, the novel technique is characterized in that the flow rate of the valve core channel element 21 of the inflation control module 2 is equal to the flow rate of the valve core of the air nozzle 14 of the object 3 (such as a tire) to be inflated, so that the inflation control module 2 can simulate the inflation flow rate of the object 3 to be inflated; then, the flow rate of the gas can be further preset and adjusted (limited) by using the regulating valve 22 of the inflation control module 2, so that the gas pressure value output by the tail end of the regulating valve 22 can be approximately the same as the internal gas pressure of the object 3 to be inflated; when the air pressure detected by the pressure sensor 23 of the inflation control module 2 reaches the preset inflation value of the object 3 to be inflated, the circuit board 24 of the inflation control module 2 controls the inflator 1 to stop operating, so that the inflator 1 can perform the inflation operation according to the air pressure required by the object 3 to be inflated.
Furthermore, the inflation control module 2 may be configured to be integrated with the inflator 1 (as shown in the first figure) within the inflator 1; alternatively, the inflation control module 2 is externally attached to the inflator 1 (as shown in the fourth drawing).
