[0001] This invention relates to the field of fire detection technology, and in particular to a pluggable fire detection device and battery pack. Background Technology

[0002] Fire detectors are the "sensory organs" of the system, and their function is to monitor whether a fire is occurring in the environment. Once a fire is detected, they convert the characteristic physical quantities of the fire, such as temperature, smoke, and gases, into electrical signals and immediately send an alarm signal to the fire alarm controller.

[0003] Existing fire detectors are installed on one side of the mounting wall. The maintenance and replacement of fire detectors are all done on the same side of the mounting wall. If the fire detector is installed inside a closed structure such as a battery pack, the closed structure needs to be disassembled and opened in order to maintain or replace the fire detector. This process is complicated and cumbersome, which affects the efficiency of fire detector maintenance and replacement. Summary of the Invention

[0004] The purpose of this invention is to provide a pluggable fire detection device and battery pack to solve the problem in the prior art that the fire detector needs to be disassembled and opened in order to repair or replace it, which affects the work efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] On one hand, the present invention provides a pluggable fire detection device, which includes:

[0007] The mounting base assembly includes a central plate, which is detachably connected to one side of the mounting wall; the central plate has a first through hole, and the mounting wall has a second through hole, with the first through hole and the second through hole being disposed opposite to each other.

[0008] The detachable assembly includes a front cover and a fire detection component, the fire detection component being detachably connected to the front cover, and the front cover being detachably connected to the center plate; the fire detection component can pass through the first through hole and the second through hole on the other side of the mounting wall.

[0009] As an alternative to the aforementioned pluggable fire detection device, the fire sensing component includes a first circuit board, a second circuit board, and a sensing labyrinth. The first circuit board is detachably connected to the front cover, the second circuit board is detachably connected to the first circuit board, and the sensing labyrinth is detachably connected to the second circuit board.

[0012] As an alternative to the aforementioned plug-in fire detection device, both the first and second seals are provided with a recess, and the middle plate is provided with a protrusion, which can be engaged with the recess.

[0013] As an alternative to the aforementioned plug-in fire detection device, the aforementioned mounting base assembly further includes a first connector, which can pass through the aforementioned middle plate and the aforementioned first seal in sequence and then connect to the aforementioned mounting wall.

[0014] As an alternative to the aforementioned plug-in fire detection device, the aforementioned mounting bracket assembly further includes a protective cover, which is located on the opposite side of the aforementioned mounting wall from the aforementioned center plate; the aforementioned first connector is detachably connected to the aforementioned protective cover.

[0015] As an alternative to the aforementioned pluggable fire detection device, the detachable assembly further includes a second connector, which can pass through the front cover and the second seal in sequence and then be connected to the middle plate.

[0016] As an alternative to the aforementioned pluggable fire detection device, the detachable assembly further includes a waterproof connector and a third seal.

[0029] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] This embodiment provides a pluggable fire detection device for sensing fires in the space on the other side of the mounting wall 6.

[0031] like Figures 1-4As shown, the plug-in fire detection device includes a mounting base assembly 1 and a detachable assembly 2. Mounting assembly 1 includes a central plate 11, which is detachably connected to one side of mounting wall 6. The central plate 11 has a first through hole 111, and the mounting wall 6 has a second through hole 61. The first through hole 111 and the second through hole 61 are arranged opposite to each other. The detachable assembly 2 includes a front cover 21 and a fire sensing component 22, which is detachably connected to the front cover 21 and the central plate 11. This allows workers to directly remove the detachable assembly 2 from the central plate 11 for easy maintenance and replacement of the fire sensing component 22. The fire sensing component 22 can pass through the first through hole 111 and the second through hole 61 to be located on the other side of the mounting wall 6 for fire sensing in the space on the other side of the mounting wall 6. This separates the mounting side and the sensing side of the fire sensing component 22 into different sides of the mounting wall 6, thus avoiding any impact on the other side of the mounting wall 6 when maintaining or replacing the fire sensing component 22, thereby improving work efficiency. Specifically, the fire sensing component 22 can sense smoke, temperature and gas on the other side of the mounting wall 6 to determine whether a fire has occurred.

[0032] like Figure 2 and Figure 3 As shown, the fire detection assembly 22 includes a first circuit board 221, a second circuit board 222, and a detection labyrinth 223. The first circuit board 221 is detachably connected to the front cover 21, the second circuit board 222 is detachably connected to the first circuit board 221, and the detection labyrinth 223 is detachably connected to the second circuit board 222. This allows the fire detection assembly 22 to be disassembled, allowing personnel to easily repair and replace damaged components as needed, avoiding the economic loss of replacing the entire fire detection assembly 22. Specifically, the front cover 21 has a nut post. A single-through copper stud passes through the first circuit board 221 and is threaded onto the nut post. Similarly, a screw passes through the detection labyrinth 223 and the second circuit board 222 and is threaded onto the single-through copper stud. Optionally, the first circuit board 221 has a first notch 2211, the second circuit board 222 has a second notch 2221, and the front cover 21 has a limiting plate 211. The limiting plate 211 can be sequentially engaged with the first notch 2211 and the second notch 2221 to limit the first circuit board 221 and the second circuit board 222. Thus, the limiting plate 211 is positioned by cooperating with the first notch 2211 and the second notch 2221, which facilitates the detachable installation of the first circuit board 221 and the second circuit board 222.

[0033] like Figure 2 and Figure 4As shown, the plug-in fire detector also includes a first sealing element 3 and a second sealing element 4. The first sealing element 3 is located between the middle plate 11 and the mounting wall 6, and the second sealing element 4 is located between the front cover 21 and the middle plate 11. The first sealing element 3 and the second sealing element 4 improve the airtightness of the plug-in fire detector, preventing smoke from the other side of the mounting wall 6 from drifting to the outside and affecting its fire sensing performance. Specifically, both the first sealing element 3 and the second sealing element 4 have a recess 5, and the middle plate 11 has a protrusion 112. The protrusion 112 can engage with the recess 5, thereby positioning the first sealing element 3 and the second sealing element 4 on the middle plate 11, facilitating their installation. Optionally, grooves are provided on both sides of the middle plate 11, and the first seal 3 and the second seal 4 are respectively embedded in the grooves on both sides of the middle plate 11. The surfaces of the first seal 3 and the second seal 4 are all provided with a continuous ring of protrusions. Thus, when the front cover 21 is pressed between the middle plate 11 and the middle plate 11, and when the middle plate 11 is pressed between the mounting wall 6, the interference fit generated by the protrusions ensures the sealing performance of the plug-in fire detection device.

[0034] like Figure 1 and Figure 2 As shown, the mounting bracket assembly 1 also includes a first connector 12, which passes sequentially through the middle plate 11 and the first seal 3 and connects to the mounting wall 6. This fixes the relative positions of the middle plate 11 and the first seal 3 when they are installed on the mounting wall 6, reducing installation difficulty. The first connector 12 also enables a detachable connection between the middle plate 11 and the mounting wall 6. The mounting bracket assembly 1 also includes a protective cover 13, located on the opposite side of the mounting wall 6 from the middle plate 11. The protective cover 13 protects the fire detection component 22 after it passes through the first through hole 111 and the second through hole 61. The first connector 12 is detachably connected to the protective cover 13, enabling a detachable connection of the protective cover 13. Specifically, the first connector 12 is a screw, which passes sequentially through the middle plate 11, the first seal 3, the mounting wall 6, and the protective cover 13 and is threaded onto a nut. Optionally, the protective cover 13 has an air inlet, allowing smoke to enter the pluggable fire detection device.

[0035] Furthermore, the detachable assembly 2 also includes a second connector 23, which passes sequentially through the front cover 21 and the second seal 4 and connects to the middle plate 11. This ensures that the relative positions of the front cover 21 and the second seal 4 are fixed when installed on the middle plate 11, thereby reducing installation difficulty. The second connector 23 also enables a detachable connection between the front cover 21 and the middle plate 11. Specifically, the second connector 23 is a screw, which passes sequentially through the front cover 21 and the second seal 4 and is threaded onto the middle plate 11.

[0036] Furthermore, the detachable assembly 2 also includes a waterproof connector 24 and a third seal 25. The waterproof connector 24 is detachably connected to the front cover 21, and the third seal 25 is located between the waterproof connector 24 and the front cover 21. External wiring can be connected to the fire sensing component 22 via the waterproof connector 24 and the front cover 21, thereby realizing the electrical connection between the fire sensing component 22 and the external wiring. By setting the waterproof connector 24 and the third seal 25, the plug-in fire detection device as a whole can achieve an IP67 protection level, thereby preventing external moisture from entering the interior of the plug-in fire detection device.

[0037] This embodiment also provides a battery pack, including the pluggable fire detection device as described above. The battery pack has a mounting wall 6 and a detachable assembly 2 located outside the battery pack. Thus, the maintenance and replacement of the fire sensing component 22 can be carried out from outside the battery pack, avoiding the difficulty of maintenance and replacement of the fire sensing component 22 caused when the pluggable fire detection device is installed inside the battery pack. At the same time, it prevents damage to the battery pack after multiple disassemblies.

[0038] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
