[0025] Please refer to Figures 1 to 3 The utility model proposes a gas detection watch 100, comprising: a gas sensor module 11 and a watch body 12; wherein, a plug-in hole 121 is provided on the peripheral side of the watch body 12; the gas sensor module 11 is plugged into the plug-in hole 121, and the gas sensor module 11 is provided with a placement cavity 114, and a sensor element 113 is provided in the placement cavity 114; the gas detection watch 100 has a daily state and a detection state. When the gas detection watch 100 is in the daily state, the peripheral wall of the plug-in hole 121 blocks the opening of the placement cavity 114, and when the gas detection watch 100 is in the detection state, the opening of the placement cavity 114 is exposed on the outer peripheral side of the watch body 12 and is connected to the external gas.

[0026] The watch body 12 is the main part of the gas detection watch 100. A control mainboard is arranged in the watch body 12 to realize the basic functions of the gas detection watch 100. The sensor element 113 is electrically connected to the control mainboard to detect the gas composition entering the placement cavity 114. The sensor element 113 may include multiple sensors for different types of gases to be suitable for complex gas environments. In daily state, the peripheral wall of the plug hole 121 blocks the opening of the placement cavity 114, effectively preventing the influence of the external environment on the sensor element 113, and protecting the stability and reliability of the sensor module. When the user wearing the gas detection watch 100 needs to perform gas detection, the gas detection watch 100 can be switched from the daily state to the detection state by pulling out or unscrewing the gas sensor module 11, so that the external gas enters the placement cavity 114, and the sensor element 113 analyzes and detects the external gas. The opening of the placement cavity 114 effectively increases the amount of gas to be detected, and improves the detection efficiency of the sensor element 113.

[0027] In this embodiment, the plug-in hole 121 includes a first orifice 1211 and a second orifice 1212, and the second orifice 1212 is arranged on the peripheral side of the meter body 12. The gas sensor module 11 includes a first end 111 and a second end 112. The first end 111 is provided with a through hole 1111, and the through hole 1111 connects the plug-in hole 121 and the placement cavity 114. The first end 111 has a movement direction approaching or moving away from the first orifice 1211, and the second end 112 is exposed at the second orifice 1212.

[0028] Please refer to Figure 3The first end 111 of the gas sensor module 11 can be provided with a screw thread, and the plug hole 121 can be provided with a corresponding thread. The second end 112 of the gas sensor module 11 is exposed at the second opening 1212, and can be used as a grip to rotate the gas sensor module 11, and adjust the gas sensor module 11 to move forward and backward in the plug hole 121, so as to switch the daily state and the detection state of the gas detection watch 100. At the same time, the setting of the screw thread and the thread can realize the fixation of the relative position of the gas sensor module 11 in the plug hole 121, thereby adjusting the opening area of ​​the placement cavity 114 in contact with the external environment, and then regulating the amount of gas entering the placement cavity 114, thereby improving the flexibility of the gas detection watch 100 for gas detection.

[0029] In other embodiments, the first section of the gas sensor module 11 and the first opening 1211 of the plug hole 121 may be connected magnetically, plugged in, snap-fitted, etc., to achieve a detachable connection between the gas sensor module 11 and the meter body 12 .

[0030] Please refer to Figure 2 In this embodiment, an air passage connected to the plug hole 121 is provided in the watch body 12, and the air passage extends along the circumference of the watch body 12. An air hole 123 connected to the external gas is provided at one end of the air passage away from the plug hole 121, and the opening direction of the air hole 123 is along the axial direction of the watch body 12. By providing the air hole 123 connected to the outside and the air passage, the gas detection watch 100 can realize continuous gas detection in daily state, reducing the user's continuous operation of the gas sensor module 11. The area of ​​the air hole 123 can be smaller than the opening area of ​​the placement cavity 114, which is suitable for scenes with high gas concentration and continuous detection.

[0031] When the pore 123 faces the side, it is easy to be blocked or blocked by clothes due to wrist movements, which can reduce the restriction on wrist movement and improve the comfort of the wearer. The axial design of the pore 123 is conducive to reducing direct contact, thereby reducing the contamination of the detection results due to factors such as dust and sweat. The airway extending along the circumferential direction effectively evens out the gas entering the pore 123, improves the gas detection accuracy of the gas sensor module 11, and the circumferential extension of the airway can reduce the thickness of the watch body 12, making the design more compact, easy to integrate into the design of the watch, and reducing space occupancy. The circumferential arrangement of the airway can also improve the strength of the watch structure, because it is integrated with the natural structural lines of the watch, and has less impact on the overall mechanical structure strength.

[0032] Furthermore, the gas detection watch 100 also includes a cover body 14 installed on the top of the watch body 12, and an air guide groove 124 is opened at the top of the watch body 12. The cover body 14 is used to block the air guide groove 124, and the connection between the cover body 14 and the periphery of the watch body 12 is enclosed to form a through hole (not shown), which is connected to the air guide groove 124, and the air hole 123 is opened at the bottom of the air guide groove 124.

[0033] The control mainboard in the meter body 12 is electrically connected to the sensor element 113, and the electrical connection can be in the form of Bluetooth, WIFI, etc. to achieve wireless remote connection. The gas detection data of the sensor element 113 can be transmitted to the control mainboard, and the control mainboard can analyze and process the gas detection data.

[0034] The surface of the cover body 14 can be equipped with a display module 141, which is electrically connected to the control main board and displays the analysis results of the gas detection data. The display module 141 arranged on the top surface of the meter body 12 can also display time, temperature, air pressure, altitude and other information. The display module 141 arranged on the top surface also makes it convenient for users to view information at any time.

[0035] When a toxic or harmful gas leak is detected, the data is transmitted to the control mainboard, and analyzed and processed by the built-in database of the control mainboard. The display module 141 sends a warning signal according to the processing result, and at the same time drives the gas detection watch 100 to vibrate, and the background synchronizes the alarm information to notify relevant personnel.

[0036] The cover body 14 also effectively isolates most foreign matter from directly entering the airway through the air hole 123. The perforations formed on the periphery of the cover body 14 are opened along the circumference of the watch body 12, avoiding the surface of the cover body 14, reducing the probability of foreign matter entering the perforations. At the same time, a filter net can be provided at the perforation to further prevent foreign matter from entering the air guide groove 124 through the perforation, thereby improving the detection accuracy and anti-environmental interference ability of the gas detection watch 100.

[0037] Furthermore, the air passage includes a plurality of branch air passages 122 , the plug hole 121 is connected to each branch air passage 122 , each branch air passage 122 is correspondingly provided with an air hole 123 , and the air guide groove 124 is annular and is connected to each branch air passage 122 at the same time.

[0038] A plurality of perforations formed by the cover body 14 and the table body 12 may be arranged at intervals along the circumference of the table body 12, and the plurality of perforations are connected to the air guide groove 124. The annular air guide groove 124 increases the amount of gas introduced to be detected. The large-volume airflow effectively increases the amount of air entering the placement cavity 114, and a large number of samples to be detected effectively improves the detection accuracy of the sensor element 113.

[0039] At the same time, the annular groove effectively increases the flow path of the gas to be detected, which is conducive to smooth and uniform airflow. The annular groove connects multiple sub-channels 122 at the same time. The gas to be detected dispersed on the annular groove enters each sub-channel 122 evenly through the air holes 123. The airflow in all directions around the meter body 12 can enter the corresponding sub-channel 122, thereby realizing uniform detection of the gas in the space and improving detection accuracy.

[0040] Specifically, the gas sensor module 11 also includes a plurality of protruding air grids 115 disposed in the placement cavity 114, and each air grid 115 is arranged at intervals and is disposed near the through hole 1111. The plurality of air grids 115 disposed at intervals allow the airflow to be more evenly distributed inside the placement cavity 114. The air grid 115 affects the airflow path through its structure, forcing the airflow to be redistributed before contacting the sensor element 113, thereby avoiding the situation where the airflow is too concentrated in certain areas. This uniform distribution helps the sensor element 113 to more effectively capture and analyze the incoming gas, and improves the measurement accuracy and response speed of the sensor element 113.

[0041] Further, one end of the multiple air grids 115 arranged at intervals away from the cavity bottom of the placement cavity 114 can be set to a wave shape. The wave-shaped design can cause a certain degree of turbulence when the airflow passes through the air grid 115, which helps to break the aggregation effect of the airflow and make it more evenly distributed on the surface of the sensor element 113. In addition, the wave-shaped design can cause more turbulence when the airflow passes through the air grid 115, increase the contact area between the gas and the surface of the sensor element 113, enhance the mixing effect between the gas and the sensor element 113, thereby improving the response speed of the sensor element 113 to the gas, and help improve the sensitivity and accuracy of the sensor element 113. The wave-shaped design can also partially absorb the noise from the airflow, reduce the interference of the noise on the detection signal of the sensor element 113, and improve the signal-to-noise ratio of the sensor element 113.

[0042] In this embodiment, a waterproof and breathable membrane may be disposed in the through hole 1111 to effectively block water vapor from entering the airway and prevent moisture from affecting the detection accuracy of the sensor element 113 .

[0043] In one embodiment, the gas detection watch 100 further includes a fan assembly 13 disposed between the cover 14 and the watch body 12, the fan assembly 13 includes a rotating shaft and a plurality of blades disposed around the rotating shaft, the fan assembly 13 rotates in a specific direction, for example, it can rotate counterclockwise, and the blades drive the external gas to be detected to enter the gas guide groove 124 from the perforation, so as to enhance the detection efficiency of the gas detection watch 100. In other embodiments, a fan assembly 13 of a smaller size can be disposed in the placement cavity 114, which can also achieve the effect of enhancing the detection efficiency.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
