[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] Please refer to the attached Figure 1-6 As shown, a surface-mounted multifunctional monitoring sensor provided by an embodiment of the utility model includes a main body 1 and a boss 2 arranged at one end of the main body 1, a first cavity 21 is arranged in the boss 2, a plurality of air holes 22 connected to the first cavity 21 are arranged on the boss 2, a second cavity 121 connected to the first cavity 21 is arranged on the main body 1, the first cavity 21 and the second cavity 121 are closed to form a detection cavity 20, a detection probe 6 is arranged in the detection cavity 20, and also includes a sealing gasket 5, a first through hole 52 adapted to the boss 2 is arranged on the sealing gasket 5, the sealing gasket 5 is covered on one end of the main body 1 where the boss 2 is arranged, and the boss 2 extends out of the sealing gasket 5 through the first through hole 52.

[0027] When in use, a hole is set on the surface of the device to be detected (such as an energy storage cabinet), and the size of the hole is just or slightly larger than the size of the above-mentioned boss 2, so that when the main body 1 is tightly installed on the surface of the device to be detected, its boss 2 penetrates into the hole, thereby connecting the internal environment of the device to form a closed detection chamber 20. In addition, when the main body 1 is tightly attached to the surface of the device to be detected, the sealing gasket 5 has a sealing effect to prevent air leakage on the contact surface and affect the normal operation of the device. Compared with the common sensors on the market that are basically installed inside the environment to be monitored, the sensor of the utility model only needs to be installed on the surface of the device to be detected to achieve the same monitoring function, thereby facilitating the operation of later maintenance or replacement of the sensor.

[0028] The sealing pad 5 is made of silica gel or soft rubber. The sealing pad 5 is provided with a plurality of sealing convex rings 51 spaced from the center to the periphery. The addition of the sealing convex rings 51 can form a multi-stage sealing effect, thereby improving the sealing reliability of the sealing pad 5.

[0029] The main body 1 is provided with a plurality of mounting through holes 14 extending from one end of the main body 1 to the other end at a portion near the edge thereof, the sealing gasket 5 is provided with a second through hole 53 at a position corresponding to the mounting through hole 14, and also includes a fastening bolt 3, the fastening bolt 3 being passed through the mounting through hole 14 and the second through hole 53 for mounting the sensor. It should be noted that when installing this sensor, it is usually only necessary to set corresponding screw holes at corresponding positions of the equipment to be installed, thereby providing a structure that is threadedly connected to the fastening bolt 3, thereby achieving installation and fixation of the sensor. It can be understood that the sensor of the utility model relies on the fastening bolt 3 to not only fix the sensor, but also to fasten the sealing gasket 5 on the sensor, so that the structure of the sensor is simple and easy to install.

[0030] The main body 1 includes an upper shell 11, a lower shell 12 and a circuit board 7. The upper shell 11 and the lower shell 12 are connected and closed to form the shell of the main body 1. The second cavity 121 is provided in the lower shell 12 and opens at the upper end of the lower shell 12. The circuit board 7 is provided at the upper end of the lower shell 12 and seals the opening of the second cavity 121. The circuit board 7 is used to cover the opening of the second cavity 121 to ensure the sealing effect of the detection cavity 20 at this end. The position of the circuit board 7 is just used to install the detection probe 6, that is, the detection probe 6 is installed on the circuit board 7 facing the opening. Therefore, this structure makes the circuit board 7 have two functions, that is, it plays the role of the circuit board 7 itself and also plays the role of sealing. In order to ensure the sealing performance between the circuit board 7 and the opening of the second cavity 121, a circle of sealing grooves 122 are provided at the upper end of the lower shell 12 around the opening of the second cavity 121, and a sealing ring 8 is provided in the sealing groove 122.

[0031] The boss 2 and the lower shell 12 are integrally formed, which not only reduces the connection structure between the boss 2 and the lower shell 12, but also ensures the sealing requirement.

[0032] It also includes a plurality of wiring terminals 4, which are installed on the circuit board 7 at intervals, and the wiring ends of the plurality of wiring terminals 4 are facing the side wall of the main body 1, and a plurality of terminal windows 13 are formed between the upper shell 11 and the lower shell 12, so that the plurality of wiring terminals 4 can extend from the terminal windows 13 one by one.

[0033] The detection probes 6 are provided with two, one of which is set as a temperature detection probe 6, and the other is set as a toxic gas detection probe 6. Therefore, the surface-mounted multifunctional monitoring sensor of the utility model includes both temperature monitoring function and toxic gas monitoring function, and is a two-in-one monitoring sensor. It is understandable that in other embodiments, the detection probe 6 can also be one, two or more detection probes 6 of different types, and the toxic gas detection probe 6 detects aldehydes, alkenes, alcohols, and carbon monoxide, hydrogen sulfide, nitric oxide, nitrogen dioxide and other gases.

[0034] In summary, the surface-mounted multifunctional monitoring sensor of the utility model only needs to be installed on the surface of the device to be detected, and the boss 2 at one end of the main body 1 can be extended into the environment to be detected to achieve real-time monitoring of the device. When the sensor is repaired or replaced later, it can be operated directly outside the device without opening the inside of the device for operation. Therefore, it is more convenient to use than the common sensors installed inside the device on the market.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model.
