[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0031] Referring to Figure 1 , Figure 2 and Figure 3 , an embodiment provided by the present utility model: a one-way carbon breath test blowing port with a cleaning cap, including a gas collecting tank 1. The middle part of the top wall of the gas collecting tank 1 is communicated with a blowing pipe 3. The bottom end of the blowing pipe 3 is communicated with a sliding pipe 4. The bottom end of the sliding pipe 4 is fixedly connected with a tension spring 5. The outer wall of the sliding pipe 4 is slidably connected with a fixed sleeve 6. The bottom wall of the fixed sleeve 6 is equidistantly provided with a plurality of air outlet valves 7. The middle part of the inner bottom wall of the gas collecting tank 1 is fixedly connected with a support rod 8. The top end of the support rod 8 is fixedly connected with a sealing ball 9. The outer wall of the sealing ball 9 is slidably connected to the inner wall of the sliding pipe 4. A folding pipe 10 is arranged in the middle and upper part of the blowing pipe 3. The middle and upper part of the rear side of the gas collecting tank 1 is fixedly installed with a one-way exhaust valve 11. A sealing device 2 is arranged on the top wall of the gas collecting tank 1;

[0032] Specifically, in the initial state, under the elastic force of the tension spring 5, the sealing ball 9 is pushed to the top of the inner wall of the sliding pipe 4. The outer wall of the sealing ball 9 is in close contact with the inner wall of the sliding pipe 4, thus blocking the connection between the sliding pipe 4 and the blowing pipe 3 and ensuring that gas will not backflow from the blowing pipe 3 into the gas collecting tank 1. When a breath test is required, the user removes the cleaning cap of the blowing pipe 3 and then presses down on the blowing pipe 3. Since the blowing pipe 3 is connected to the sliding pipe 4, this action will cause the sliding pipe 4 to move downward as well. As the sliding pipe 4 moves downward, the sealing ball 9 will slide downward inside the sliding pipe 4 and finally reach the middle position of the sliding pipe 4. At this time, the sealing ball 9 no longer blocks the connection between the sliding pipe 4 and the blowing pipe 3, and the user can blow air into the gas collecting tank 1 through the blowing pipe 3. Since the bottom wall of the fixed sleeve 6 is equidistantly provided with a plurality of air outlet valves 7 for guiding the gas blown into the fixed sleeve 6 into the gas collecting tank 1. When the gas accumulates to a certain extent in the gas collecting tank 1, the gas can be discharged through the one-way exhaust valve 11. The one-way exhaust valve 11 can automatically open when the internal pressure of the gas collecting tank 1 is too high, further ensuring the safety of the gas collecting tank 1. The folding pipe 10 is used to connect the blowing pipe 3 and the gas collecting tank 1, increasing the flexibility and mobility of the blowing pipe 3, effectively preventing gas backflow, and ensuring the accuracy and safety of the breath test.

[0033] Referring to Figure 1 , Figure 2 and Figure 4The sealing device 2 includes a sealing nozzle 201, the outer wall of the sealing nozzle 201 is threadedly connected with a sealing cover 202, the inner top wall of the sealing cover 202 is fixedly connected with an inner sealing ring 203, the outer wall of the inner sealing ring 203 is fixedly connected with a plurality of rubber sealing rings 204, and the middle part of the inner top wall of the sealing nozzle 201 is fixedly connected with a tube top fitting cover 205, and the bottom end of the tube top fitting cover 205 fits with the top end of the blowing tube 3;

[0034] Specifically, before the device is used, the sealing device 2 plays a vital role. The sealing device 2 is mainly composed of a sealing nozzle 201 and a sealing cover 202, which are tightly matched through a threaded connection. An inner sealing ring 203 is fixed to the inner top wall of the sealing cover 202, and a plurality of rubber sealing rings 204 are fixedly connected to the outer wall of the inner sealing ring 203. These rubber sealing rings 204 can fit tightly on the inner wall of the sealing nozzle 201 to form a reliable sealing layer, which effectively prevents external air from entering the gas collecting tank 1. The middle part of the inner top wall of the sealing nozzle 201 is also fixed with a rubber sealing ring 203. There is a tube top fitting cover 205, the bottom end of which fits tightly with the top end of the air blowing tube 3, ensuring that the connection between the air blowing tube 3 and the gas collecting tank 1 can also achieve a good sealing effect. When the subject blows air into the gas collecting tank 1 through the air blowing tube 3, the gas can smoothly enter the gas collecting tank 1 without any leakage. At the same time, the design with a cleaning cap allows the air port to be cleaned before the test. This design ensures the accuracy of the test results, achieves a good sealing state inside the gas collecting tank 1 during the breath test, and ensures the accuracy of the test results and sanitary safety.

[0035] Reference Figure 2 , a fixed block 12 is fixedly connected to the left side of the top wall of the gas collecting tank 1, and two locking rings 13 are fixedly connected to the bottom end of the outer wall of the sealing cover 202, and a rotating ring 14 is rotatably connected between the two adjacent locking rings 13, and the rotating ring 14 is rotatably connected to the fixed block 12; two fixing screws 15 are passed through the left and right sides of the gas collecting tank 1, and the outer walls of the multiple fixing screws 15 are fixedly connected to handles 16; a horizontal bracket 17 is fixedly connected to the front side of the top wall of the gas collecting tank 1, and a level 18 is fixedly connected to the inner wall of the horizontal bracket 17;

[0036] Specifically, the fixed block 12 forms a connection structure with the rotating ring 14 and the locking ring 13, and can ensure that the sealing cover 202 can rotate freely. The sealing cover 202 will not be discarded at will due to negligence of the user when the gas collecting tank 1 is placed in use. The handle 16 is fixed to the left and right sides of the gas collecting tank 1 with the fixing screws 15, which provides the function of convenient for the user to hold and move the gas collecting tank 1. The horizontal bracket 17 is used to support the spirit level 18 to ensure that it can accurately indicate the horizontal state of the gas collecting tank 1 during the test. Since the gas collecting tank 1 is filled with liquid for sealing, in order to prevent the liquid from tilting too much when collecting gas, resulting in a decrease in sealing performance, the horizontal state of the liquid inside the gas collecting tank 1 can be intuitively understood through the spirit level 18.

[0037] Refer to Figure 1 and Figure 3 On the front side of the gas collecting tank 1, a pressure gauge 19 is fixedly connected, and on the front side of the pressure gauge 19, a pointer 20 is fixedly connected; on the bottom wall of the gas collecting tank 1, an anti-slip pad 21 is fixedly connected, and the anti-slip pad 21 is made of rubber; on the outer wall of the fixed sleeve 6, a bubble-breaking net 22 is fixedly connected, and the outer wall of the bubble-breaking net 22 is fixedly connected to the middle and lower part of the inner wall of the gas collecting tank 1.

[0038] Specifically, the pressure gauge 19 and the pointer 20 are used to display the pressure state inside the gas collecting tank 1. During the exhalation test, it is ensured that the pressure of the collected gas is within a safe range. The anti-slip pad 21 made of rubber can increase the friction between the gas collecting tank 1 and the placement surface, preventing bumps caused by sliding or moving during the test placement. During the exhalation test, since a certain amount of liquid is stored in the gas collecting tank 1 to ensure the sealing effect, bubbles will be generated during exhalation, which will affect the accuracy of the test results. The bubble-breaking net 22 can break the bubbles, making the exhaled gas enter the gas collecting tank 1 more evenly and stably.

[0039] Working principle: In the initial state, under the elastic force of the tension spring 5, the sealing ball 9 is pushed to the top of the inner wall of the sliding tube 4. The outer wall of the sealing ball 9 is in close contact with the inner wall of the sliding tube 4, thus blocking the connection between the sliding tube 4 and the blowing tube 3 and ensuring that gas will not backflow from the blowing tube 3 into the gas collecting tank 1. When an exhalation test is required, the user removes the cleaning cap of the blowing tube 3 and then presses down on the blowing tube 3. Since the blowing tube 3 is connected to the sliding tube 4, this action will cause the sliding tube 4 to move downward as well. As the sliding tube 4 moves downward, the sealing ball 9 will slide downward inside the sliding tube 4 and finally reach the middle position of the sliding tube 4. At this time, the sealing ball 9 no longer blocks the connection between the sliding tube 4 and the blowing tube 3, and the user can blow air into the gas collecting tank 1 through the blowing tube 3. Since a plurality of air outlet valves 7 are equidistantly arranged on the bottom wall of the fixed sleeve 6 for guiding the gas blown into the fixed sleeve 6 into the gas collecting tank 1, when the gas accumulates to a certain extent inside the gas collecting tank 1, the gas can be discharged through the one-way exhaust valve 11. The one-way exhaust valve 11 can automatically open when the internal pressure of the gas collecting tank 1 is too high, further ensuring the safety of the gas collecting tank 1. The folding tube 10 is used to connect the blowing tube 3 and the gas collecting tank 1, increasing the flexibility and mobility of the blowing tube 3.

[0040] And before the device is used, the sealing device 2 plays a crucial role. The sealing device 2 is mainly composed of a sealing nozzle 201 and a sealing cover 202, which are tightly fitted through threaded connection. An inner sealing ring 203 is fixed to the inner top wall of the sealing cover 202, and a plurality of rubber sealing rings 204 are fixedly connected to the outer wall of the inner sealing ring 203. These rubber sealing rings 204 can closely fit on the inner wall of the sealing nozzle 201 to form a reliable sealing layer, effectively preventing external air from entering the gas collecting tank 1. In the middle of the inner top wall of the sealing nozzle 201, a pipe top fitting cover 205 is also fixed, and its bottom end closely fits with the top end of the blowing pipe 3, ensuring that the connection between the blowing pipe 3 and the gas collecting tank 1 can also achieve a good sealing effect. When the subject blows air into the gas collecting tank 1 through the blowing pipe 3, the gas can smoothly enter the gas collecting tank 1 without any leakage.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
