In addition, unless otherwise specified, "multiple" means two or more.

[0034] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0035] like Figure 1-9 As shown, the installation structure of the nitric oxide sensor provided by some embodiments of the present invention, the nitric oxide sensor 200 includes a body 201, a plug 202 and a protrusion 203 arranged on the upper surface of the body 201, the upper surface of the protrusion 203 has a sensing area 204, the sensing area 204 is used to analyze the nitric oxide component in the gas through an electrochemical reaction, and the plug 202 is used to transmit the data detected by the nitric oxide sensor 200. The installation structure 100 includes a base 1, a slide plate 2, a first socket 3 and a second socket 4.

[0036] The interior of the base 1 has a accommodating cavity 11 and a detection cavity 12 arranged on the accommodating cavity 11, the accommodating cavity 11 penetrates downwardly through the base 1, the main body 201 is installed in the accommodating cavity 11, the protrusion 203 is installed in the detection cavity 12, the upper part of the base 1 has a slide groove 13, the bottom of the slide groove 13 has an opening 14, the opening 14 is connected to the accommodating cavity 11, and the plug 202 is located below the opening 14.

[0037] The slide plate 2 is slidably installed in the slide groove 13 , and the positions of the first socket 3 and the second socket 4 are adjusted by sliding the slide plate 2 .

[0038] The first socket 3 is mounted on the slide plate 2 and the bottom of the first socket 3 extends downward out of the slide plate 2 . When the first socket 3 moves to the opening 14 , the first socket 3 can be connected to the plug 202 .

[0039] The second socket 4 is installed on the slide plate 2 and the bottom of the second socket 4 extends downward from the slide plate 2. The second socket 4 and the first socket 3 are arranged along the sliding direction of the slide plate 2. When the second socket 4 moves to the opening 14, the second socket 4 can be connected to the plug 202.

[0040] In this embodiment, when the slide plate 2 slides in the slide groove 13, the first socket 3 or the second socket 4 is located on the opening 14 and connected to the plug 202. Therefore, the positions of the first socket 3 and the second socket 4 are adjusted by the slide plate 2 to meet the connection requirements of the plugs 202 of the two types of nitric oxide sensors 200.

[0041] Based on the above structural setting, since the slide plate 2 can be slidably installed in the slide groove 13, the position of the first socket 3 and the second socket 4 can be adjusted by sliding the slide plate 2 to meet the connection requirements of the plug 202 of the two types of nitric oxide sensors 200, so that users can replace them independently without returning to the factory for repair. In addition, the first socket 3 and the second socket 4 are both installed on the slide plate 2, and the position is adjusted by sliding, and they only move in the plane, making the structure compact.

[0042] like Figure 5 As shown, in some embodiments, the base 1 has a connecting channel 15 inside, the connecting channel 15 is used to connect the detection chamber 12 and the accommodating chamber 11, the diameter of the detection chamber 12 is larger than the diameter of the connecting channel 15, and the diameter of the connecting channel 15 is larger than the diameter of the protrusion 203. When in use, the nitric oxide sensor 200 is installed in the base 1, and the upper surface of the protrusion 203 passes through the connecting channel 15 and is located in the detection chamber 12, so that the sensing area 204 can detect the nitric oxide content of the gas in the detection chamber 12.

[0043] like Figure 3-5As shown, in some embodiments, the detection cavity 12 passes through the base 1 upwards, and the mounting structure 100 further includes a ventilation plate 5, which is mounted on the base 1. The ventilation plate 5 is used to cover the detection cavity 12, and an air inlet connector 51 and an air outlet connector 52 are respectively provided on both sides of the ventilation plate 5, and the air inlet connector 51 and the air outlet connector 52 are both connected to the detection cavity 12. When in use, the air inlet connector 51 is connected to the breathing handle through a pipeline, and the user can put on the breathing handle to input the exhaled gas into the detection cavity 12 through the pipeline, and the gas is detected by the sensing area 204 located in the detection cavity 12, and then discharged through the air outlet connector 52.

[0044] Furthermore, the bottom of the ventilation plate 5 has a convex ring 53, which is arranged in the detection cavity 12, and the inner wall of the convex ring 53 has a sealing ring 54, and the top of the protrusion 203 is installed in the convex ring 53 through the sealing ring 54. The upper part of the detection cavity 12 is sealed by the ventilation plate 5, and the lower part of the detection cavity 12 is sealed by the protrusion 203, so that the sensing area 204 detects the relatively closed detection cavity 12 space, reduces the mixing of air, and improves the detection accuracy of the nitric oxide sensor 200.

[0045] like Fig. 9 As shown, in some embodiments, the ventilation plate 5 has a through hole 55 in the middle, and the mounting structure 100 further includes a circuit board 6, which is mounted on the ventilation plate 5. A temperature and humidity sensor is integrated on the circuit board 6. The temperature and humidity sensor can measure the temperature and humidity of the gas in the detection chamber 12 through the through hole 55, which is conducive to calibrating the detection data of the nitric oxide sensor 200. In addition, the portion where the temperature and humidity sensor passes through the through hole 55 is sealed with an O-ring.

[0046] like Figure 3 As shown, in some embodiments, both sides of the accommodating cavity 11 extend outward to form a cavity 16, and the mounting structure 100 further includes a bottom plate 7, which is mounted on the bottom of the base 1, and the bottom plate 7 is used to cover the accommodating cavity 11 and the cavity 16. When the body 201 of the nitric oxide sensor 200 is mounted in the accommodating cavity 11 of the base 1, the space of the cavity 16 is conducive to the user holding the nitric oxide sensor 200, and it is convenient to disassemble and assemble the nitric oxide sensor 200.

[0047] like Figure 5 As shown, in some embodiments, the slide 13 includes an extension portion 131, an expansion portion 132 disposed below the extension portion 131, and a receiving portion 133 disposed below the expansion portion 132. The extension portion 131 extends upward from the upper portion of the base 1, the slide plate 2 is slidably disposed in the expansion portion 132, the opening 14 is located in the receiving portion 133, the width of the expansion portion 132 is a, the width of the slide plate 2 is b, and the width of the extension portion 131 is c, then a>b>c is satisfied. The above-mentioned size setting enables the slide plate 2 to move horizontally along the expansion portion 132 to prevent the slide plate 2 from sliding upward out of the extension portion 131.

[0048] like Figure 6 As shown, in some embodiments, baffles 21 are installed at both ends of the upper portion of the slide plate 2, and the sum of the height of the baffle 21 and the height of the slide plate 2 is greater than the height of the expansion portion 132. The above-mentioned size setting ensures that the slide plate 2 will not slip out of the expansion portion 132 horizontally during the horizontal movement along the expansion portion 132.

[0049] like Figure 3 As shown, in some embodiments, the slide plate 2 has two limiting holes 22, and the mounting structure 100 further includes a limiting bolt 8, which passes through the base 1 and is installed in one of the limiting holes 22. By installing the limiting bolt 8 in different limiting holes 22, the first socket 3 or the second socket 4 can be fixed on the opening 14, so as to adapt to the installation of two types of nitric oxide sensors 200.

[0050] like Fig.10 As shown, detectors provided by other embodiments of the present invention include the above-mentioned mounting structure 100 of the nitric oxide sensor. Specifically, the mounting structure 100 is installed in a housing 300 of the detector.

[0051] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
