Description

Technical Field

[0001] The present application relates to the technical field of gas detection, and in particular to a pluggable gas detection head. Background Art

[0002] Gas detection heads are an important part of gas detection equipment. Their main function is to work with gas monitoring controllers to detect the concentration of specific substances in the gas in the environment. Gas detection heads are widely used in different industries, such as oil and gas industry, semiconductor manufacturing, chemical plants, power plants, wastewater treatment plants, boiler rooms and hospitals. In these occasions, gas detection heads are used to detect flammable and toxic gases to ensure the safety of workers and the normal operation of equipment.

[0003] The current gas detection head can usually only be connected to a single detection device, so it can only use a single detection mode. Different detection modes are required in different detection scenarios. When the gas concentration is low and rapid detection is required, pump suction detection is used. When the gas concentration is high and precise detection is required, diffusion detection is more suitable. However, monitoring equipment can usually only perform single-mode detection, and changing the detection mode usually requires the use of different detection equipment. Summary of the invention

[0004] In order to solve the problem that the gas detection head cannot be applied to multiple detection modes, the present application provides a pluggable gas detection head.

[0005] The pluggable gas detection head provided in this application adopts the following technical solution:

[0006] A pluggable gas detection head comprises:

[0007] The detection body has a gas connection port, a pump suction port and an electrical connection port, the electrical connection port is used to connect an external detection device, the pump suction port is used to connect an external pump, and the electrical connection port and the pump suction port are arranged on the same side of the detection body;

[0008] The plug-in cap is connected to the same side of the pump suction port and is used to fix the connection between the detection head and the external detection equipment;

[0009] An air inlet pipe, connected to the gas connection port, is used to absorb the detection gas.

[0010] By adopting the above technical solution, the detection body is the main structure of the detection head, and a sensor is installed inside to detect the gas concentration by diffusion detection. After the intake pipe absorbs the gas, the gas enters the detection body through the gas connection port, and the external device can receive the detection information by connecting the electrical connection port. At the same time, when the external pump is connected to the pump suction port, the detection head can be converted to pump suction detection. And it can be fixed on the external detection device or external pump through the plug-in cap, which can play the role of fixing the detection head.

[0011] Optionally, the plug cap is an arch-shaped structure, which can be sleeved on the outside of the external detection device and partially expose the external detection device.

[0012] By adopting the above technical solution, the arch-shaped plug-in cap can expose part of the external device while being sleeved on the external device. When the external device is provided with buttons or screens, the buttons or screens can be exposed, so that the detection head can be used normally even in the sleeved state.

[0013] Optionally, the pump suction port and the electrical connection port are arranged on the inner side of the plug cap.

[0014] By adopting the above technical solution, since the plug-in cap is sleeved on the external device, and the pump suction port and the electrical connection port are arranged on the inner side of the plug-in cap, the external device can complete the connection with the detection head on the inner side when it is sleeved, thereby ensuring the stability of the connection.

[0015] Optionally, the surface of the detection body has a diffusion port for diffusing the gas into the detection body.

[0016] By adopting the above technical solution, during diffusion detection, the gas will enter the detection body from the air inlet pipe and be emitted to the outside through the diffusion port. The diffusion port can ensure the balance of internal and external air pressure of the detection body, which is conducive to the diffusion of gas into the detection body.

[0017] Optionally, the detection body is further provided with a diffusion button, which is used to open and close the diffusion port so that the gas enters the external pump through the pump suction port.

[0018] By adopting the above technical solution, when the detection head is connected to the external pump, the pump suction port is connected to the external pump. At this time, the gas needs to be sucked into the external pump through the pump suction port, and the diffusion port is closed by the diffusion button so that the gas will no longer diffuse through the diffusion port, so that the gas in the detection body can enter the external pump, which is beneficial to improve the efficiency and accuracy of the detection.

[0019] Optionally, the air intake duct has a filter.

[0020] By adopting the above technical solution, the filter can filter small particles in the gas so that the gas will not bring external solid debris into the detection body, thereby ensuring the normal operation of gas detection.

[0021] Optionally, a snap-fitting pattern is provided on the inner side of the plug-in cap.

[0022] By adopting the above technical solution, the snap-fitting pattern can increase the socket stability between the plug-in cap and the external device, thereby ensuring stability during the gas detection process.

[0023] Optionally, friction patterns are provided on the outer side of the plug-in cap.

[0024] By adopting the above technical solution, the friction pattern can prevent the detection head from sliding during the picking process, and the friction pattern can make the detection head more convenient to operate during the process of installing or removing the external device.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. After the air intake pipe absorbs the gas, the gas enters the detection body through the gas connection port. The external device can receive the detection information by connecting to the electrical connection port. At the same time, when the external pump is connected to the pump suction port, the detection head can be converted to pump suction detection. And it can be fixed on the external detection device or external pump through the plug-in cap, which can play the role of fixing the detection head;

[0027] 2. Since the plug-in cap is sleeved on the external device, by arranging the pump suction port and the electrical connection port on the inner side of the plug-in cap, the external device can be connected to the detection head on the inner side when it is sleeved, thereby ensuring the stability of the connection.

[0032] The present application is further described in detail below in conjunction with the accompanying drawings.

[0033] A pluggable gas detection head, with reference to the figure, comprises a detection body 1, a pluggable cap 2 and an air inlet pipe 3. The detection body has a gas connection port 11, a pump suction port 12 and an electrical connection port 13, wherein the electrical connection port 13 is used to connect to the corresponding interface of an external detection device to realize data transmission or power supply. The pump suction port 12 is connected to an external pump, and the gas to be detected is sucked into the external pump through the detection body 1 by the suction action of the external pump to realize pump suction detection. The pluggable cap 2 adopts an arch-shaped structure design, which can be easily sleeved on the outside of the external detection device, and through the matching connection with the pump suction port 12 or the electrical connection port 13, the detection head and the external detection device can be quickly fixedly connected. When the pluggable cap 2 is sleeved on the external device, the external device will be partially exposed by the pluggable cap 2 to facilitate the operation or observation of the external device. The electrical connection port 13 and the pump suction port 12 are arranged on the same side of the detection body 1, and are both arranged on the inner side of the plug cap 2. When the external device is plugged into the plug cap 2, the connection with the electrical connection port 13 and the pump suction port 12 can be covered, thereby facilitating the stability of the connection. The air inlet pipe 3 is connected to the gas connection port 11, and is used to absorb gas into the detection body 1.

[0034] Referring to the figure, a diffusion port 14 and a diffusion button 15 are provided on the surface of the detection body 1. The diffusion button 15 is connected to the diffusion port 14 and is used to control the opening and closing state of the diffusion port 14. When the detection head is in diffusion detection, the diffusion port 14 is opened to balance the air pressure inside and outside the detection body 1, and the gas can freely diffuse into the detection body 1. When the detection head is in pump suction detection, the diffusion port 14 is closed, so that the gas enters the connected external pump through the air inlet pipe 3 and the pump suction port 12, avoiding the diffusion of gas from the diffusion port 14, and preventing particles from entering the detection head from the diffusion port 14.

[0035] Referring to the figure, a snap-in pattern 21 is added to the inner side of the plug-in cap 2. The snap-in pattern 21 can cooperate with the corresponding structure on the external detection device to enhance the connection stability. The design of the snap-in pattern 21 can ensure that during the detection process, the connection between the detection head and the external device will not be easily loosened due to vibration or other external forces, thereby ensuring the smooth progress of the detection. A friction pattern 22 is added to the outer side of the plug-in cap 2. The friction pattern 22 can increase the friction force of the plug-in cap 2 during the plug-in and pull-out process, allowing the operator to perform the plug-in and pull-out operations more conveniently and labor-savingly. Especially when the hands are wet or gloves are worn, the design of the friction pattern can effectively prevent the plug-in cap from slipping during the plug-in and pull-out process.

[0036] Referring to the figure, a filter 31 is provided on the air intake pipe 3, and the filter 31 is provided on the path of the gas entering the air intake pipe 3, and is used to filter out solid particles in the gas entering the air intake pipe 3. In this way, these solid particles can be prevented from interfering with the detection results, the accuracy and reliability of the detection can be improved, and the internal components of the detection head can be protected from damage by solid particles.

[0037] The implementation principle of the embodiment of the present application is as follows: the detection head needs to be connected to an external device when performing detection. The detection head applies different detection modes by connecting different external devices. When the external device is connected, the plug-in cap 2 is sleeved on the external device, so that the detection head and the external device are fixed. When diffusion detection is applied, the external device is connected only to the electrical connection port 13, and the diffusion port 14 is opened by the diffusion button 15, so that diffusion detection can be used. When pump-suction detection is applied, the external pump is respectively connected to the pump suction port 12 and the electrical connection port 13, and the diffusion port 14 is closed by the diffusion button 15, so that the external pump inhales external gas through the detection head, thereby realizing pump-suction detection.

[0038] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
