The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0022] See also Figure 1 and Figure 2, this embodiment provides a quick-install combustible gas detector, which includes a main control board 3, a power cord 2, a sensor 11, a housing 1, a display screen, a waterproof male connector 7, a waterproof female connector 8, a connecting wire and an installation ear piece 12. Among them, the main control board 3 and other electrical components are arranged inside the housing 1. The connection gaps of the housing 1 are all provided with sealing members, such as sealing strips, sealants, etc., which are used to seal the housing 1 to prevent water from seeping into the housing 1 and causing damage to the electrical components inside the housing 1. In this embodiment, two connection ports and a reserved port are provided on the housing 1 at intervals of 90°. The two connection ports are fixedly connected with the waterproof male connector 7. The conductive parts of the pins of the two waterproof male connectors 7 are fixedly connected with the connecting wire. The connecting wire is arranged in the connection port, one section of which is fixedly connected with the conductive part of the waterproof male connector 7, and the end thereof away from the waterproof male connector 7 is fixedly connected with the main control board 3. Since the two ends of the connecting wire do not need to be considered for subsequent disassembly, they can be directly welded and fixed. The traditional wiring method has to consider the problem of disassembly and assembly, and can only be screwed on by screws, which is not as firm as welding. The waterproof male connector 7 and the waterproof female connector 8 are a set of electrical connectors. The waterproof male connector 7 is provided with a plug or pin for conducting electricity, and the waterproof female connector 8 is provided with a jack or notch that cooperates with the plug. The waterproof female connector 8 and the waterproof male connector 7 can be plugged in and out to realize the circuit connection and disconnection between the male and female connectors. To this end, according to different types of cables, the conductive part of one waterproof female connector 8 is fixedly electrically connected to the end of the power cord 2. The conductive part of the other waterproof female connector 8 is fixedly electrically connected to the sensor 11. The quick installation of the wiring of the combustible gas detector can be realized by plugging and unplugging between the waterproof male connector 7 and the waterproof female connector 8. For the convenience of installation, some mounting ears 12 can also be provided on the outer wall of the housing 1 to install and fix the housing 1. In other embodiments, a reserved opening can also be provided on the housing 1, which is used to reserve a channel connecting the inside and outside of the housing 1. A plug screw 4 is connected to the reserved opening, and a second sealing ring 10 is provided between the plug screw 4 and the reserved opening to prevent water from seeping into the housing 1 from the reserved opening. According to actual needs, when the reserved opening is not needed, the plug screw 4 is used for blocking. When the reserved opening is needed, the plug screw 4 is removed, which is equivalent to an additional connection port, and can be used in the same manner as the connection port structure in the above embodiment.

[0023] In other specific embodiments, in order to further improve the sealing effect. A threading rubber ring 5 can be sleeved on the connecting line. The threading rubber ring 5 is embedded in the connecting port, which is used to prevent water from entering the shell 1 at the connecting port. A sealing ring gasket 6 can also be provided between the threading rubber ring 5 and the waterproof male connector 7, a first sealing ring 9 can be provided between the waterproof male connector 7 and the waterproof female connector 8, and a second sealing ring 10 can be provided between the waterproof male connector 7 and the connecting port, etc., to further prevent or reduce water from entering the shell 1 at the connecting port. In addition, in other embodiments, a display screen can also be provided on the front of the shell 1. The front of the shell 1 is made of transparent material, and the display screen is provided inside the shell 1, or the display screen is embedded in the shell 1, and its periphery is sealed by sealant. The display screen is electrically connected to the main control board 3, and is used to display information such as detection parameters of some sensors 11.

[0024] To sum up, regarding the wiring problem of the detector, we changed the traditional method of removing the cover to connect the wiring, and changed it to a method where the main control board 3 and the control circuit are connected before leaving the factory, and a structural design with a reserved external quick-plug port is provided. The main control and electrical component parts of the detector are designed as an integrated structure with the shell 1. The sensor 11 and the power supply part adopt a module design, and use a plug-in and double sealing ring leak-proof connection method. When they expire, they can be replaced by plugging and unplugging directly without removing the shell 1. This installation and wiring saves time and effort, is quick and convenient, and does not require high-altitude wiring, nor does it require the shell 1 to be disassembled in a vaporous environment to expose the internal electrical components. At the same time, this design can further seal the shell 1, and by reducing the disassembly and assembly of the outer shell, it can avoid or reduce the problem of water seepage caused by poor sealing.

[0025] The technical features of the above-described embodiments may be arbitrarily combined. 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.

[0026] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
