[0032] As described in the background section, the most common alcohol testing devices on the market are stick-shaped alcohol testing sticks used by traffic police. These devices are relatively large, not only costly, but also inconvenient for ordinary consumers to carry. Their design and main function are geared towards professional applications in law enforcement scenarios, rather than meeting the daily needs of individual users. For individual users, existing alcohol testing devices are clearly insufficient in terms of portability.

[0033] To solve this technical problem, this utility model provides a portable alcohol detection device.

[0034] For details, please refer to Figures 1-10 The portable alcohol testing device specifically includes:

[0035] The protective housing 1 has several air inlets 2 and several air outlets 201.

[0037] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0038] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0039] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0040] Example 1, please refer to Figures 1-10 A portable alcohol detection device includes a protective housing 1 with several air inlets 2 and several air outlets 201. Inside the protective housing 1 are a data conversion chip 4, a data processing chip 5, and an alcohol sensor 6, located between the air inlets 2 and outlets 201. An interface module 3 is located at the end of the protective housing 1 and is connected to the data conversion chip 4. Both the data conversion chip 4 and the alcohol sensor 6 are connected to the data processing chip 5. This device, through the interface module 3, can connect to a user's smart terminal (such as a mobile phone) for power supply and data transmission. Data collected by the alcohol sensor 6 is uploaded to the user's smart terminal in real time by the interface module 3, greatly improving the user experience. The device is also more compact, making it easy for users to carry and perform tests anytime, anywhere.

[0041] Furthermore, such as Figure 1 , Figure 3 and Figure 7As shown, the protective housing 1 includes a first housing 101 and a second housing 102. The air inlet 2 and the air outlet 201 are both opened on the second housing 102. The alcohol sensor 6 is installed inside the second housing 102. The protective housing 1 is used to provide physical protection for the data conversion chip 4, the data processing chip 5 and the alcohol sensor 6.

[0042] Furthermore, the interface module 3 is disposed on the first housing 101, and the data conversion chip 4 and the data processing chip 5 are both installed inside the first housing 101.

[0043] Furthermore, interface module 3 is a USB interface, a Type-C interface, or a Lightning interface to adapt to different user smart terminals, enabling the device to be compatible with the vast majority of smart terminals on the market. Whether it is a mobile phone or tablet using the Android system or a device using the Apple system, users can easily connect the device to their smart terminal, expanding the applicability of the device.

[0044] Furthermore, a connector is provided between the first housing 101 and the second housing 102, which is used to connect the first housing 101 and the second housing 102.

[0045] Example 2 further optimizes the portable alcohol testing device provided in Example 1, specifically, as follows: Figures 1-3 As shown, the connector is a connecting shell 103, which is fixedly connected between the first shell 101 and the second shell 102. The first shell 101, the second shell 102 and the connecting shell 103 are integrally formed and are L-shaped so that the user can observe while blowing air.

[0046] Example 3 further optimizes the portable alcohol detection device provided in Example 1, specifically, as follows: Figures 4-6 As shown, the connector includes two first connecting seats 8 fixedly installed at the end of the first housing 101 away from the interface module 3. A damping shaft 801 is provided between the two first connecting seats 8. The damping shaft 801 is connected to a second connecting seat 802. The second connecting seat 802 is connected to a third connecting seat 803, and the third connecting seat 803 is fixedly connected to the second housing 102. Through the cooperation of the first connecting seats 8, the damping shaft 801, the second connecting seat 802, and the third connecting seat 803, the first housing 101 and the second housing 102 can be connected together, so that the first housing 101 and the second housing 102 can be folded, further improving portability. The angle between the first housing 101 and the second housing 102 can be adjusted for user convenience.

[0047] Furthermore, a protective component is provided between the ends of the second housing 102 and the first housing 101. The protective component is used to protect the air inlet 2 and the interface module 3, reducing the possibility of damage or contamination before use.

[0048] Furthermore, such as Figures 4-6 As shown, the protective component includes a protective cover 7, on which a first slot 701 is provided, and the inner wall of the first slot 701 is inserted into the second housing 102, so that the protective cover 7 can be installed on the second housing 102 to form a protection, effectively reducing the situation of impurities contaminating the air inlet 2 and providing a more reliable protective effect.

[0049] Furthermore, such as Figures 4-6 As shown, the protective cover 7 is also provided with a second slot 702. The inner wall of the second slot 702 is inserted into the interface module 3 so that the protective cover 7 can protect the interface module 3 and reduce the possibility of damage. When in use, the protective cover 7 can be removed and the second housing 102 or the first housing 101 can be rotated to adjust its angle.

[0050] Reference Figures 8-10 V+ and V- are the positive and negative terminals of the power supply. The input is 3V-5V, which powers the data processing chip 5 and the alcohol sensor 6. After the alcohol sensor 6 is powered on, it starts to detect the alcohol concentration in the air and converts it into an electrical signal. When air is blown into the air inlet 2, the alcohol sensor 6 can generate different electrical signals according to the alcohol content in the blown air. After receiving the electrical signal from the alcohol sensor 6, the data processing chip 5 converts it into an alcohol concentration value according to its built-in algorithm and transmits it to the data conversion chip 4 through the data transmission interface. The data conversion chip 4 converts the data into data that can be transmitted by the interface module 3 and connects with the user's smart terminal to transmit the alcohol concentration value to the user's smart terminal for display.

[0051] Taking interface module 3 as a USB interface as an example, when using a USB interface, the data conversion chip 4 is a USB data conversion chip. After the alcohol sensor 6 detects the alcohol concentration, it generates an analog electrical signal (such as voltage change). This signal is transmitted to the data processing chip 5 through the hardware circuit. The data processing chip 5 converts the analog signal into a digital signal and calculates the accurate alcohol concentration value through built-in algorithms (such as linear calibration and temperature compensation). The data conversion chip 4 receives the serial digital signal from the data processing chip 5 and converts it into a signal that can be transmitted through the USB interface so that the signal can be transmitted to the user's smart terminal through the USB interface.
