fig. 2 is the utility model discloses a gas monitoring devices's of automatically cleaning split structure chart.
In the figure: 1. a control circuit board; 2. a gas sensor base; 3. a sampling device; 4. sealing the shell; 5. an air intake duct; 6. an air outlet pipeline.
Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments:
as shown in fig. 1 and 2, the utility model provides a gas monitoring device of automatically cleaning, it is including control circuit board, and the integration has control circuit on the control circuit board 1, install gas sensor unit, sampling device 3 on the control circuit board 1, the gas sensor unit includes gas sensor base 2, and the inside gas sensor that is provided with of gas sensor base 2, the outside of gas sensor base still is provided with a sealed shell 4, sealed shell 4 and gas sensor base 2 sealing connection, the inside gas sensor that sets up of gas sensor base 2 can begin to have the through-hole at top or lateral part to supply gas output.
The control circuit board 1 is provided with a communication interface and a power interface. The control circuit plays a main control role, the communication interface can be externally connected with wireless communication or wired communication, and the power supply interface is externally connected with a power supply device to provide electric energy for the whole device. The gas sensor does not need to guarantee only one kind of gas actually, and can be a sensor module and detect various gases. For example, as shown in fig. 2, the gas sensor base may include four sensor bases, each sensor base corresponds to one gas sensor and corresponds to one through hole, and the gas flows into another gas sensor through the through hole after being detected by one sensor, and is finally output.
Sampling device 2, gas sensor, communication interface and power source all are connected with control circuit, and admission line 5 is connected to gas sensor's one end, and admission line 5 can set up on sealed shell 4, and the other end and sampling device 3 intercommunication, sampling device 3 still are connected with pipeline 6 of giving vent to anger, and pipeline 6 of giving vent to anger is connected with air supply unit and purifier respectively, and sampling device 3 is used for inhaling gas sensor with the gas in air supply unit or the purifier. When gas is input into the gas sensor base 2 through the gas inlet pipe 5, the gas is respectively detected through the gas sensors corresponding to the four gas sensor bases 2 in sequence, and other finally detected gas is output to the sampling device by the suction force of the sampling device and then is discharged.
In order to make the device more integrated, a shell is further arranged outside the device, the control circuit board 1, the gas sensor unit and the sampling device 3 are all located in the shell, and the gas inlet pipeline 5 and the gas outlet pipeline 6 both penetrate through the shell to be communicated with the outside.
Specifically, the sampling device 3 is a sampling air pump, which provides suction under the control of the control circuit to draw air into the gas sensor base 2 for detection.
The utility model discloses a purifier is the steel bottle, be equipped with compressed air in the steel bottle. The output of the gas source device is gas to be detected, the gas output by the gas source device is detected after the gas output by the gas source device is detected, the purifying device outputs clean gas under the pump suction of the sampling device, the gas circuit and the sensor in the device are cleaned in a back flushing manner in an intermittent manner, and the gas in the detected environment remained in the device is effectively removed, so that the sensor is ensured to have long service life and high use precision.
Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes are intended to fall within the scope of the claims.
