Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of human breath analysis, in particular to a quantitative analysis device for human breath. Background Art
[0002] Exhaled gas is a complex mixture, primarily composed of nitrogen, oxygen, carbon dioxide, water vapor, and small amounts of other gases. Analyzing exhaled gas can be used to assess human health. Publication No. CN221635848U discloses a "human exhaled gas collection device and analysis equipment thereof" that addresses the technical drawbacks of residual gas or mixed gases such as ambient gas in the channel. However, similar analysis devices still suffer from numerous drawbacks in actual use. For example, they lack the ability to dry and sterilize the analysis mechanism after use. Storing and testing exhaled gas can cause moisture inside the analysis mechanism. Prolonged moisture inside the analysis mechanism can breed bacteria, which can contaminate the device and pose a risk to subsequent testers. Furthermore, nasal discharge cannot be filtered during exhaled gas collection. When the collected gas contains nasal discharge, the collection mechanism can become clogged, contaminating it or even flowing into the analysis mechanism, causing damage. To address these issues, we have designed a quantitative analysis device for exhaled gas. Utility Model Content

[0023] Based on the above-mentioned structural setting, the quantitative analysis device of human exhaled gas consists of an analysis mechanism 1 and a collection mechanism 2, wherein the analysis mechanism 1 is an analysis and detection mechanism for human exhaled gas, with the help of the analysis mechanism 1, the gas can be quantitatively analyzed and detected, and the collection mechanism 2 is a collection mechanism for human exhaled gas. Specifically, during operation, the collection cover 201 is placed outside the human nose, so that the gas exhaled by the person through the nose can be collected through the collection cover 201, and the threaded ring 204 at the bottom of the conduction tube 203 is threadedly installed on the threaded tube 106 at the top of the one-way valve 105, so that the conduction tube 203 and the collection cover 201 can be installed and connected, and the assembly ring 205 is embedded in the interior of the assembly groove 202, so that the filter 20 6 is installed inside the collection cover 201, and the filter screen 206 can be used to filter the gas exhaled by the nose when the collection cover 201 collects it, so as to prevent mucus from entering the conduction tube 203 and causing blockage, and the filter screen 206 can be installed and disassembled and replaced through the assembly ring 205 and the assembly groove 202, so that the collection cover 201 can be reused, and the conduction tube 203 can conduct the gas collected by the collection cover 201, and when the collected gas enters the one-way valve 105 through the conduction tube 203, it can be unidirectionally circulated, so as to prevent the gas conducted to the inside of the quantitative bag 4 from flowing back. When the collected gas enters the quantitative bag 4 through the one-way valve 105, it will prop it up, and the quantitative bag 4 will prop up the collected gas after it is propped up. The gas is quantitatively stored, and the analysis sensor 401 can analyze and detect the quantitative gas collected in the quantitative bag 4, thereby realizing the function of quantitative collection and analysis and detection of the gas exhaled by the human body. The quantitative bag 4 will push the contact plate 701 at the input end of the pressure switch 7 when it is inflated and expanded. The pressure switch 7 is connected to the device alarm mechanism, so that when the quantitative bag 4 is expanded, the pressure switch 7 is turned on through the contact plate 701. When the pressure switch 7 is turned on, the device alarm mechanism is energized, so that it can prompt the person when exhaling, so that the person can stop blowing. The control main board 6 installed inside the shell 101 is connected to the pressure switch 7 and the analysis sensor 401 through a wire, so that the control main board 6 can connect the pressure switch 7 and the analysis sensor The data detected by the sensor 401 is collected.

The discharge solenoid valve 402 can be opened after the analysis sensor 401 completes the gas analysis and detection inside the quantitative bag 4. The fan pipe 403 rotates when the discharge solenoid valve 402 is opened, so that the gas analyzed inside the quantitative bag 4 can be extracted and discharged, and the air intake solenoid valve 407 will also be opened when the discharge solenoid valve 402 is opened. Therefore, when the fan pipe 403 is operating, the external gas will enter the interior of the quantitative bag 4 through the air intake solenoid valve 407.Thus, by opening the two sets of valve tubes and rotating the fan tube 403, the interior of the quantitative bag 4 can be ventilated and dried, preventing the collected gas from causing the interior of the quantitative bag 4 to remain in a moist state for a long time and breeding bacteria. The air inlet cover 408 can protect the air inlet solenoid valve 407, preventing dust and foreign matter in the air from entering the quantitative bag 4 through the air inlet solenoid valve 407.
