[0040] Embodiment 1:

[0041] The camera equipped with the odor sensing function provided in this embodiment is suitable for scenes such as factory monitoring and food monitoring, and is particularly suitable for scenes such as factory monitoring. It can effectively warn of the occurrence of accidents. In this embodiment, the structure of the camera equipped with the odor sensing function is improved to make its heat dissipation performance better and its stability is guaranteed.

[0042] like Figure 1 to Figure 2 As shown, the camera equipped with the odor sensing function in this embodiment includes a housing 100, a detection base 200, a first ventilation part 300, a second ventilation part 400 and a fan assembly (not shown). The shell 100 is provided with a mounting groove 101; the detection base 200 is provided with a camera sensor 500, which is installed in the mounting groove 101, and is provided with a detection gas groove 201, in which a gas sensor (not shown) is provided, and the gas sensor may be a carbon monoxide sensor, a methane sensor, etc., without limitation; the first ventilation part 300 is provided on the detection base 200, and is used to connect the detection gas groove 201 with the environment. In the present embodiment, the first ventilation part 300 may be an air exchange hole provided on the groove wall of the detection gas groove 201; the second ventilation part 400 is installed on the detection base 200, and can move between a first position and a second position; the fan assembly is provided in the detection gas groove 201, and is located between the first ventilation part 300 and the second ventilation part 400. The fan assembly may be a small fan or a micro fan, and can generate airflow without limitation.

[0043] A surrounding gap 102 is formed between the detection base 200 and the groove wall of the installation groove 101; when the second ventilation section 400 is located at the first position, the second ventilation section 400 connects the detection gas groove 201 and the surrounding gap 102, and the gas sensor operates with low power consumption; when the second ventilation section 400 is located at the second position, the second ventilation section 400 connects the detection gas groove 201 and the environment, and the gas sensor operates with full power consumption.

[0044] Specifically, the camera with the odor sensing function in this embodiment operates with the second ventilation part 400 at the first position and the low-power gas sensor under normal circumstances. At this time, the gas can enter the surrounding gap 102, fully taking away the heat generated by the camera sensor 500 and the gas sensor, extending the service life of the camera, and reducing the failure caused by long-term overheating; when at least one of the camera sensor and the gas sensor detects abnormal data, the second ventilation part 400 at the second position and the high-power gas sensor are operated. At this time, the detection gas groove 201 is connected to the environment through the two ventilation parts, realizing rapid analysis and response to the scene, playing the role of early warning, so as to ensure the reliability of this solution. Therefore, the camera with the odor sensing function of this solution is not easily damaged by heat accumulation under long-term normal operation, and can also respond quickly when abnormal data appears, so as to respond quickly to the scene, and has the advantage of high reliability, that is, this solution has the advantages of good heat dissipation and high reliability.

[0045] In this embodiment, if Figures 2 to 5 As shown, the second ventilation part 400 includes a ventilation tube 410 slidably connected to the detection base 200, and the ventilation tube 410 can move between a first position and a second position; ventilation holes 420 are opened on the tube wall of the ventilation tube 410; when the second ventilation part 400 is located in the first position, the ventilation holes 420 are set toward the surrounding gap 102; when the second ventilation part 400 is located in the second position, the ventilation holes 420 are located outside the shell 100.

[0046] Furthermore, a groove wall of the installation groove 101 is provided with an avoidance hole 103, and the ventilation pipe 410 is slidably connected to the avoidance hole 103; a movable groove 104 is provided at the edge of the avoidance hole 103; a rib portion 430 is protruding from the edge of the pipe mouth of the ventilation pipe 410, and a spring unit is installed between the rib portion 430 and the bottom wall of the movable groove 104; when the second ventilation portion 400 is located in the first position, the spring unit is in a compressed state, and the rib portion 430 is located in the movable groove 104.

[0047] A switch slot 105 is provided on the upper slot wall of the movable slot 104, and the switch slot 105 extends to the end face of the shell 100; the switch slot 105 is slidably connected with a switch block 600; when the second ventilation part 400 is located in the first position, the switch block 600 abuts against the retaining edge part 430, and the switch block 600 is located on the side of the retaining edge part 430 away from the spring unit.

[0048] As a preferred embodiment, an electromagnet unit 700 is installed on the end face of the housing 100, and a magnetic block is embedded in the end of the switch block 600 protruding from the switch slot 105 corresponding to the electromagnet unit 700; after power is turned on, the polarity of the electromagnet unit 700 and the magnetic block are the same. For example, when abnormal data is collected, the control unit can energize the electromagnet unit 700. At this time, the switch block 600 is lifted up by the magnetic repulsion provided by the electromagnet unit 700. Therefore, the end of the switch block 600 is completely retracted into the switch slot 105 and no longer abuts against the retaining edge portion 430. Then, under the action of the spring unit, the ventilation tube 410 slides out by pushing the retaining edge portion 430, so that the ventilation hole 420 moves from the surrounding gap 102 to the environment. At this time, the wind direction of the fan assembly changes (from the original first ventilation section 300-detection gas slot 201-second ventilation section 400 to the second ventilation section 400-detection gas slot 201-first ventilation section 300), so that the gas in the environment enters the detection gas slot 201 through the second ventilation section 400 for detection by the gas sensor, so as to improve the detection accuracy. It also means that the second ventilation section 400 is located in the second position, and the gas sensor can operate in high power mode to achieve rapid response to the scene.

[0049] As another optional implementation, a handle groove 610 is provided at the end of the switch block 600 protruding from the switch groove 105 so that an operator can adjust the position of the switch block 600 .

[0050] As another optional implementation, a plurality of buffer sponge blocks 800 are installed in the surrounding gap 102 .

[0051] In summary, the camera equipped with odor sensing function provided in this embodiment has the advantages of good heat dissipation performance, high stability, and long life.

[0054] It should be pointed out that the monitoring device in this embodiment also includes a control unit such as an integrated small CPU, a Raspberry Pi control board, and a single-chip microcomputer to analyze the information collected by the camera sensor and the gas sensor respectively; when the second ventilation part 400 is in the first position, the gas sensor can operate in a low-power mode and the detection frequency can be appropriately reduced; when abnormal data is collected, the control unit can energize the electromagnet unit 700, so that the second ventilation part 400 is in the second position, and the gas sensor can operate in a high-power mode to achieve a rapid response to the scene.

[0055] In summary, the monitoring device provided in this embodiment has the advantages of good heat dissipation performance, high stability, and long life.
