Abstract
Description
Technical Field
[0001] This utility model relates to smoke detectors, specifically a wireless intelligent smoke fire detector. Background Technology
[0002] Smoke is a substance produced in the early stages of combustion during a fire, and smoke detectors are currently the most widely used fire detection instruments in the world.
[0003] Smoke detectors are installed in many places to detect fires in a timely manner and ensure that firefighters can be notified promptly. However, it is common for smoke detectors to be removed without authorization. Once a smoke detector is removed without authorization, it will be unable to detect a fire in time and send a signal, thus failing to notify the firefighters in time and causing serious accidents.
[0004] Furthermore, it is common for installers to forget to install batteries when installing smoke detectors, and this often goes unnoticed. Therefore, a wireless intelligent smoke detector fire alarm is proposed. Utility Model Content
[0005] The purpose of this invention is to solve the above problems by proposing a wireless intelligent smoke detector fire alarm.

[0025] The following description, in conjunction with the accompanying drawings, further illustrates the wireless intelligent smoke detector fire alarm of this utility model.
[0026] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.
[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly; for example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0028] See Figure 1-8 As shown, a wireless intelligent smoke detector includes a housing 1, a top cover 2 installed above the housing 1, a bottom shell 3 installed below the housing 1, a battery and circuit board 5 installed inside the housing 1, and an alarm 6 connected to the circuit board 5; characterized in that it also includes an anti-disassembly structure, which includes a limiting platform 11 on the housing 1, an elastic locking platform 31 on the bottom shell 3 corresponding to the limiting platform 11, a cuttable positioning point 12 on the housing 1 and located on one side of the limiting platform 11, an anti-disassembly contact 51 on the circuit board 5 with one end protruding from the bottom of the housing 1, and an elastic pressing member 32 on the bottom shell 3 corresponding to the contact.
[0029] By setting up an anti-disassembly structure, it is possible to prevent personnel from removing the smoke detector 6 without authorization, which would affect fire prevention and control. It is also possible to prevent the smoke detector 6 from being removed without authorization, which would result in the inability to automatically alarm in time in the event of a fire or other situation, thus avoiding accidents.
[0030] Before the bottom shell 3 is connected to the shell 1, if it is necessary to prevent disassembly, the positioning point 12 is cut off with scissors. After cutting, the elastic locking platform 31 is locked in the original position of the positioning point 12 after the bottom shell and the shell 1 are screwed together. The position of the elastic platform is limited by the limiting platform 11 to prevent the shell 1 and the bottom shell from being screwed apart.
[0031] When it is detachable, there is no need to cut the positioning point 12. At this time, when screwing, the elastic locking platform 31 is squeezed by the positioning point 12 and expands outward to be on the positioning point 12. At this time, the limiting platform 11 does not limit the elastic locking platform 31, and the shell 1 and the bottom shell 3 can be screwed apart.
[0032] After the bottom shell 3 is screwed onto the housing 1, the elastic pressing member 32 on the bottom shell 3 moves to the anti-tamper contact 51 as it rotates and squeezes the anti-tamper contact 51. When the housing 1 and the bottom shell 3 are disconnected, the anti-tamper contact 51 is no longer squeezed. An alarm message can be sent to the remote control platform through the communication module to indicate that there is an abnormality in the smoke detector 6. At the same time, the LED light 8 can be controlled to flash and the buzzer 81 can be sounded by the controller on the circuit board 5.
[0033] In one embodiment, the device further includes a plurality of L-shaped slots 13 disposed on the housing 1 and L-shaped blocks 33 disposed on the bottom housing 3 that are adapted to the L-shaped slots 13. The housing 1 and the bottom housing 3 are screwed together and fixed by the L-shaped blocks 33 and the L-shaped slots 13. By setting the L-shaped blocks 33 and the L-shaped slots 13, the housing 1 and the bottom housing 3 can be screwed together by the L-shaped blocks 33 and the L-shaped slots 13, which makes disassembly and assembly convenient.
[0034] In one embodiment, the housing 1 is provided with a battery slot 14, and a plurality of batteries are installed in the battery slot 14; it also includes a foolproof structure provided on the housing 1 and the bottom shell 3;
[0035] The foolproof structure includes a plurality of blocks 7 on the housing 1 corresponding to a plurality of batteries and having a right-angled trapezoidal cross section, an elastic clip 71 on the bottom housing 3 corresponding to a plurality of batteries, and a limiting clip 72 on the elastic clip 71 corresponding to the blocks 7 and having one side set as an inclined surface.
[0036] It also includes a protrusion 73 on the elastic clip 71 corresponding to the battery position;
[0037] When the bottom shell 3 is installed on the housing 1, if the battery slot 14 of the housing 1 contains a battery, when the bottom shell 3 is screwed on, the battery exerts an upward squeezing force on the boss 73 when it contacts the battery. The boss 73 drives the elastic locking strip 71 to move upward, so that the limiting locking point 72 passes the stop block 7. At this time, the bottom shell 3 can be screwed on the housing 1.
[0038] If a battery is missing from the battery compartment 14, the protrusion 73 will not be subjected to the squeezing force of the battery, causing the elastic retaining strip 71 to not move upward. As a result, when screwing the bottom shell 3, the limiting retaining point 72 on the bottom shell 3 will contact the stop block 7 and be blocked by the stop block 7, preventing it from passing over the stop block 7 and causing the bottom shell 3 and the shell 1 to be unable to be screwed and fixed, which is used to remind the operator that a battery is missing.
[0039] In one embodiment, the circuit board 5 is provided with a communication module, which includes a WiFi module and a 5G module; the communication module is used to connect to a remote control platform, and signal connection can be made via WiFi or 5G communication.
[0040] In one embodiment, it also includes an LED light 8 mounted on the circuit board 5 and a buzzer 81 mounted on the top cover 2 and connected to the circuit board 5. The LED light 8 and the buzzer 81 are used to issue alarms and prompts.
[0041] In one embodiment, the device further includes a slot 15 disposed on the housing 1, an insert 21 disposed on the top cover 2 and adapted to the slot 15, a locking block 16 disposed in the slot 15, and a locking groove 22 disposed on the insert 21 and adapted to the locking block 16. When the top cover 2 is connected to the housing 1, the insert 21 is inserted into the slot 15 until the locking block 16 is locked in the locking groove 22, thereby completing the engagement between the top cover 2 and the housing 1.
[0042] The installation process of this utility model is as follows: During installation, it is determined whether the positioning point 12 needs to be cut. For example, in order to prevent the housing 1 from being disassembled without authorization, the positioning point 12 is cut before the housing 1 is connected to the bottom shell 3. At this time, the anti-tampering relies on the limiting platform 11 to limit the elastic card platform 31 to restrict the rotation of the housing 1 or the bottom shell 3, and then combined with the anti-tampering contact 51 for double protection.
[0043] If the positioning point 12 is not cut, the anti-tamper contact 51 will play a protective role against tampering. After it is removed, the signal will be generated by the remote control terminal, and the staff will go to the site to investigate.
[0044] During installation, first fix the bottom shell 3 to the wall or other installation location using screws or other means. Then install the battery into the battery slot 14 of the shell 1. Then install the shell 1 onto the bottom shell 3. During installation, first align the L-shaped slot 13 on the shell 1 with the L-shaped block 33 on the bottom shell 3. Then rotate the shell 1 so that the L-shaped block 33 is inserted into the L-shaped slot 13 and the installation is complete.
[0045] Then insert the plug 21 on the top cover 2 into the slot 15 of the housing 1 until the card block 16 in the slot 15 is engaged with the slot 22 of the plug 21, thus completing the installation of the top cover 2.
[0046] The scope of protection of this utility model is not limited to the above embodiments and their variations. Conventional modifications and substitutions made by those skilled in the art based on the content of these embodiments are all within the scope of protection of this utility model.
