[0053] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] like Figures 1 to 6As shown, the present application provides a gas detection device, which includes a housing 10, a detection component 20, a sampling component 30 and a control component 40. The housing 10 has a accommodating cavity 11 and an opening 12 that are interconnected. The detection component 20 includes a detection shell 21 and a plurality of detection elements 22. The detection shell 21 has a detection cavity, an air inlet and an air outlet. The air inlet and the air outlet are both connected to the detection cavity. The air inlet is arranged in the opening 12. The plurality of detection elements 22 are distributed in annular intervals along the axis of the detection shell 21. The plurality of detection elements 22 are used to detect different components in the gas. The sampling component 30 has a sampling cavity 311. One end of the sampling cavity 311 has an air outlet 312. The other end of the sampling cavity 311 is detachably connected to the air inlet. The control component 40 is arranged between the detection chamber and the sampling chamber 311. The control component 40 has a relatively set blocking state and an avoidance state. When the control component 40 is in the blocking state, the control component 40 can block the air inlet. When the control component 40 is in the avoidance state, the sampling chamber 311 can be connected with the detection chamber through the air inlet.

[0055] By applying the technical solution of the present application, the detection component 20 is arranged in the accommodating cavity 11, the air inlet of the detection shell 21 is penetrated in the opening 12, a plurality of detection elements 22 are arranged in the detection shell 21, and the distances between the plurality of detection elements 22 and the air inlet are the same. The sampling cavity 311 of the sampling component 30 is connected with the air inlet, and the control component 40 is arranged between the detection cavity and the sampling cavity 311, and the control component 40 can block or open the air inlet. With such arrangement, the plurality of detection elements 22 can detect different components in the gas at the same time, thereby shortening the path of gas flow and greatly improving the detection speed. At the same time, when the gas detection device is not in use, the air inlet can be closed to prevent dust and other impurities from entering the detection cavity and damaging the detection element 22, thereby ensuring the subsequent normal use of the detection element 22 and improving the service life of the detection element 22.

[0056] The detection element 22 may be a sensor.

[0057] Furthermore, a handle is provided at the top of the housing 10 to facilitate carrying and use by staff.

[0058] like Figure 2 As shown, the gas detection device also includes a disinfection component 50 and a pump body 60. The disinfection component 50 is arranged in the accommodating chamber 11, and the disinfection component 50 has an air inlet pipe 51, an air outlet pipe 52 and a barrel body 53, and the barrel body 53 has a disinfection chamber, one end of the air inlet pipe 51 is connected to the air outlet, the other end of the air inlet pipe 51 is connected to the disinfection chamber, and one end of the air outlet pipe 52 is connected to the disinfection chamber, and the disinfection chamber is used to place the disinfection solution. The pump body 60 is arranged in the accommodating chamber 11, and the pump body 60 has a gas inlet and a gas outlet, the gas inlet is connected to the other end of the air outlet pipe 52, and the gas outlet is used to discharge the gas to the outside of the shell, and the pump body 60 is used to drive the gas flow.

[0059] With such a configuration, the pump body 60 can drive the gas to circulate in the detection chamber, the air inlet pipe 51, the barrel body 53 and the air outlet pipe 52. With such a configuration, the normal detection of the gas by the detection element 22 can be ensured. At the same time, the gas is sterilized by the sterilization solution and then discharged through the pump body 60, so as to avoid the exhaust gas containing more germs and ensure the health of the staff.

[0060] like Figure 1 As shown, the outer wall of the housing 10 is fixedly connected with an injection pipe 56 and a discharge pipe 57, the injection pipe 56 is located above the discharge pipe 57, the injection pipe 56 and the discharge pipe 57 are connected with the barrel body 53, and the ends of the injection pipe 56 and the discharge pipe 57 are detachably connected with rubber plugs. Such a configuration makes it easy to inject the disinfection solution into the barrel body 53 and to discharge the ineffective disinfection solution.

[0061] Specifically, the pump body 60 is a micro vacuum pump. An exhaust port is formed through one side of the housing 10, and the gas outlet of the pump body 60 is connected to the exhaust port.

[0062] like Figure 2 As shown, the detection assembly 20 also includes a flow divider 23 and a flow converging member 24. The flow divider 23 is arranged in the detection chamber, and the side of the flow divider 23 close to the air inlet has an arc structure, and a plurality of flow divider channels 231 are arranged on the arc structure, and the plurality of flow divider channels 231 are distributed in an annular interval, and the plurality of flow divider channels 231 are arranged one by one with the plurality of detection elements 22.

[0063] Such a configuration facilitates the dispersion of the gas, and enables the gas to be more evenly diffused into the multiple branch channels 231, thereby facilitating the simultaneous detection of multiple detection elements 22, thereby ensuring the detection accuracy of the detection elements 22 and improving the detection speed.

[0064] The diverter channel 231 is distributed at the edge of the diverter member 23, which can prevent gas from remaining between the gas inlet and the diverter member 23, thereby ensuring the accuracy of detection when the gas detection device is used again.

[0065] The confluence piece 24 is arranged in the detection cavity, and the confluence piece 24 is arranged at one end of the diversion piece 23 close to the air outlet. The confluence piece 24 is provided with a gathering groove 241, multiple detection grooves 242 and multiple confluence channels 243. The multiple detection grooves 242 are arranged one by one with the multiple confluence channels 243, and the multiple detection grooves 242 are arranged correspondingly with the multiple detection elements 22. The detection elements 22 are placed in the corresponding detection grooves 242. The detection grooves 242 are connected with the corresponding diversion channels 231. One end of the confluence channel 243 is connected with the corresponding detection groove 242. The other end of the confluence channel 243 is connected with one end of the gathering groove 241, and the other end of the gathering groove 241 is connected with the air outlet.

[0066] In this way, by setting up multiple detection slots 242, multiple independent detection spaces can be formed to ensure the concentration of the gas, and each detection space does not interfere with each other, so that the data detected by the detection element 22 is more accurate. At the same time, the detection elements 22 in multiple detection slots 242 perform detection at the same time, which greatly improves the detection speed. The gathering slot 241 can collect the detected gas together and discharge it centrally, which is convenient for the disinfection of the gas.

[0067] Furthermore, the detection shell 21 includes a guide portion 211, which is arranged between the air inlet and the diverter 23, and the diameter of the guide portion 211 gradually increases in the direction approaching the diverter 23, and multiple diverter channels 231 are arranged gradually approaching the center line of the diverter 23 in the direction away from the guide portion 211.

[0068] Such a configuration facilitates the gas to flow smoothly to the diversion channel 231, avoids the noise caused by sudden changes in gas flow rate, and improves the user experience of the staff.

[0069] Specifically, the detection shell 21 further includes a main body portion 213 , a detection cavity is formed between the main body portion 213 and the flow guide portion 211 , and the flow splitter 23 and the flow converging member 24 are disposed in the main body portion 213 .

[0070] like Figure 3 and Figure 4 As shown, the control assembly 40 also includes a connecting seat 41 , a blocking block 42 , a connecting member 43 and a resetting member 44 .

[0071] The connecting seat 41 is fixed in the air inlet, and has a sliding cavity 411 and a communicating port 412 which are connected to each other. The communicating port 412 is arranged on a side of the sliding cavity 411 away from the sampling assembly 30 .

[0072] The blocking block 42 is slidably disposed in the sliding cavity 411. When the control component 40 is in the blocking state, the blocking block 42 blocks the connecting port 412. When the control component 40 is in the avoiding state, the control component 40 is disposed away from the connecting port 412. The blocking block 42 has a connecting port 421 and a rotating cavity 422 that are interconnected. The connecting port 421 is disposed on a side of the rotating cavity 422 close to the sampling component 30.

[0073] One end of the connecting member 43 is fixed in the sampling cavity 311, and the other end of the connecting member 43 is rotatably arranged in the rotating cavity 422. The connecting member 43 has a sliding position and an abutting position arranged relatively. When the connecting member 43 is in the sliding position, the connecting member 43 can pass through the connecting port 421. When the connecting member 43 is in the abutting position, the connecting member 43 can abut against the inner wall at the connecting port 421 to drive the blocking block 42 to slide. The reset member 44 is arranged between the blocking block 42 and the sliding cavity 411.

[0074] In the present application, the connecting member 43 includes a fixing rod 431 and a connecting block 432 connected to each other, one end of the fixing rod 431 is fixed in the sampling cavity 311, the other end of the fixing rod 431 is fixedly connected to the connecting block 432, and the connecting block 432 is rotatably arranged in the rotating cavity 422. The connecting block 432 is adapted to the structure of the fixing rod 431 and the connecting port 421.

[0075] The reset member 44 can drive the blocking block 42 to move toward the communication port 412 .

[0076] In this way, the sampling chamber 311 is connected to the air inlet, and the connecting block 432 is inserted into the rotating chamber 422 through the connecting port 421. The sampling component 30 is rotated so that the connecting block 432 abuts against the inner wall of the connecting port 421, and the sampling component 30 is pulled away from the housing 10. The connecting port 412 is opened, so that the gas blown in through the blowing port 312 can enter the detection component 20.

[0077] When the detection is completed, the staff releases the sampling component 30, the reset member 44 drives the blocking block 42 to block the connecting port 412, and rotates the sampling component 30 in the opposite direction, rotates the connecting block 432 to a setting corresponding to the connecting port 421, and then pulls the sampling component 30 to remove the sampling component 30. This can prevent dust and other impurities from entering the detection component 20 when the gas detection device is not in use, thereby preventing the detection component 20 from being damaged.

[0078] Furthermore, the above structure is simple and convenient for opening and closing the communication port 412 .

[0079] Furthermore, two abutting protrusions 423 are provided in the rotating cavity 422, and the two abutting protrusions 423 are respectively provided on both sides of the connecting port 421. When the connecting block 432 rotates in the rotating cavity 422 to abut against the two abutting protrusions 423, the connecting block 432 can drive the blocking block 42 to move in the sliding cavity 411. Optionally, the abutting protrusions 423 can adopt an elastic structure, and such a configuration can buffer the movement of the connecting block 432, avoid a large collision between the connecting block 432 and the blocking block 42, and ensure the normal operation of the connecting member 43 and the blocking block 42.

[0080] At the same time, since the blowing time of the staff is short, the workload of pulling the sampling assembly 30 to move the blocking block 42 away from the connecting port 412 is small and can be ignored.

[0081] like Figure 2 As shown, the detection housing 21 has a communication pipe 212, and the communication pipe 212 has an air inlet.

[0082] The sampling assembly 30 includes a sampling shell 31 and a drying member 32. The sampling shell 31 has a sampling cavity 311, one end of the sampling shell 31 has an air outlet 312, the drying member 32 is arranged at one end of the sampling cavity 311 close to the air outlet 312, the other end of the sampling shell 31 can be slidably sleeved on the outside of the connecting tube 212, and the sampling shell 31 can rotate relative to the connecting tube 212, the sampling shell 31 has a first limit angle and a second limit angle that are relatively set, when the sampling shell 31 is located at the first limit angle, the connecting member 43 is located at the sliding position, and when the sampling shell 31 is located at the second limit angle, the connecting member 43 is located at the abutting position.

[0083] With such arrangement, the sampling assembly 30 has a simple structure, is easy to assemble and disassemble, and is convenient for the staff to operate. In addition, the drying element 32 can dry the gas to prevent the water vapor from damaging the detection element 22 .

[0084] Furthermore, the sampling assembly 30 further includes a support rod 33, the support rod 33 is fixed in the sampling cavity 311, and one end of the fixing rod 431 is fixedly connected to the support rod 33. Such a configuration facilitates the fixed connection between the connecting member 43 and the sampling assembly 30.

[0085] like Figure 1 and Figure 5 As shown, the outer wall of the connecting tube 212 is provided with an abutting plate 2121, and the abutting plate 2121 is provided with a connecting rod 2122. The outer wall of the sampling shell 31 is provided with a limit plate 313, and the limit plate 313 is provided with an arc groove 3131. The connecting rod 2122 is slidably inserted into the arc groove 3131. When the connecting rod 2122 abuts against both ends of the arc groove 3131, the sampling shell 31 is respectively located at a first limit angle and a second limit angle.

[0086] Such a configuration can limit the depth of the connecting block 432 moving into the rotating chamber 422 and the rotation angle of the sampling shell 31 . The configuration has a simple structure, and is convenient for processing the connecting tube 212 and the sampling shell 31 and for operation by staff.

[0087] like Figure 3 As shown, the inner wall of the connecting seat 41 is provided with a guide groove 413, and the outer wall of the blocking block 42 is provided with a guide block 424, and the guide block 424 is slidably arranged in the guide groove 413. Such an arrangement can ensure the stability of the blocking block 42 moving in the sliding cavity 411, prevent the blocking block 42 from tilting during the movement, and prevent the blocking block 42 from falling off from the sliding cavity 411.

[0088] like Figure 2As shown, the disinfection component 50 includes a plurality of barrel bodies 53 , with a connecting pipe 54 between two adjacent barrel bodies 53 , and one-way valves 55 are provided at one end of the air inlet pipe 51 located in the barrel body 53 , both ends of the connecting pipe 54 , and one end of the air outlet pipe 52 located in the barrel body 53 .

[0089] Such a configuration can ensure the sterilization effect of the gas and prevent bacteria in the gas from affecting the health of other workers. In addition, it can prevent gas reflux, ensure the health of workers using the gas detection device, and prevent the gas carrying the sterilization solution from damaging the detection element 22.

[0090] Specifically, each barrel body 53 is correspondingly provided with a liquid injection pipe 56 and a liquid discharge pipe 57 .

[0091] The air inlet end of the air inlet pipe 51 and the air outlet end of the connecting pipe 54 are located in the disinfection solution, and the air inlet end of the connecting pipe 54 and the air outlet end of the air outlet pipe 52 are located above the liquid surface of the disinfection solution.

[0092] like Figure 2 As shown, an ultraviolet lamp 70 is arranged in the detection cavity. The ultraviolet lamp 70 can irradiate and sterilize the detection cavity.

[0093] Furthermore, in order to ensure the disinfection effect of the ultraviolet lamp 70, the diverter 23 and the confluence member 24 are both made of transparent material, so that the diverter channel 231, the gathering groove 241, the detection groove 242 and the confluence channel 243 can be disinfected, making the disinfection of the detection component 20 more thorough.

[0094] The gas detection device further includes a circuit board 81, a control terminal 82, an interface 83 and a battery 84.
