Description

Technical Field

[0001] The utility model relates to the technical field of smoke sensors, in particular to a smoke sensor with high fire monitoring and detection accuracy. Background Art

[0002] High-precision smoke sensors are mainly used to detect whether there is smoke in the environment, such as detecting thick smoke during a fire. When the smoke probe encounters smoke or certain special gases, the resistance inside the smoke probe changes, generating an analog value to control it. The smoke sensor uses the principle that the resistance of the smoke-sensitive element changes due to the influence of smoke to send an analog signal corresponding to the smoke concentration to the host.

[0003] Existing smoke sensors can only passively allow air to enter through the vents, so the smoke sensors have poor sensitivity and are difficult to sense fires in a timely manner, which reduces the practicality of the smoke sensors.

[0004] An existing patent (publication number: CN219418240U) discloses a smoke sensor with high fire monitoring detection accuracy, including a sensor body, a control button fixedly connected to the surface of the sensor body, a heat dissipation device provided on the side of the sensor body, and the heat dissipation device including an outer frame, the outer frame is fixedly connected to the sensor body, the inner wall of the outer frame is slidably connected to the inner frame, the surface of the inner frame is fixedly connected to a support rod, the surface of the support rod is fixedly connected to a motor, the output end of the motor is fixedly connected to a rotating shaft, the surface of the rotating shaft is fixedly connected to a fan blade, the side of the outer frame is fixedly connected to a limit plate, the surface of the limit plate is threadedly connected to a screw, the screw penetrates the outer frame, and the inner frame is located between the screw and the sensor body, and the fan blade is driven to rotate by the motor, thereby pushing the airflow to pass through the inside of the smoke sensor, solving the problem that the fog sensor can only passively allow air to enter through the vent.

[0005] However, the above technical solution still has certain defects. When conducting regular inspections on smoke sensors, do not manually use a ladder to approach the smoke sensor and then inspect the smoke sensor. During the entire inspection process, workers need to keep their heads up to operate. During the operation, workers' eyes are swollen and foreign objects can easily enter, and they are prone to fatigue during the inspection process. Therefore, a smoke sensor with high fire monitoring detection accuracy is proposed. Utility Model Content

[0006] Based on this, the purpose of the present invention is to provide a smoke sensor with high fire monitoring detection accuracy to solve the technical problems raised in the above background.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a smoke sensor with high fire monitoring detection accuracy, comprising a mounting seat, wherein a sensing body is arranged at the bottom end of the mounting seat;

[0008] The mounting base includes a top plate, which is fixedly connected to the roof by bolts, and the bottom end of the top plate is fixedly connected to two groups of brackets, and the inner wall of each group of the brackets is rotatably connected to a group of rotating plates, and the side walls of each group of the rotating plates are fixedly connected to a group of protrusions, and the rotating plates are provided with torsion springs at the connection with the brackets;

[0009] The sensing body comprises a shell, and two groups of limit blocks are fixedly connected to the side wall of the shell, each group of limit blocks is slidably connected to the inner wall of a group of brackets, and the outer wall of the limit block abuts against the outer wall of a group of protrusions.

[0010] As a preferred technical solution of a smoke sensor with high fire monitoring and detection accuracy of the utility model, the inner wall of the shell is fixedly connected with a circuit board, and the outer wall of the circuit board is electrically connected with the sensor body.

[0011] As an optimal technical solution for a smoke sensor with high fire monitoring and detection accuracy of the utility model, a buzzer is fixedly connected to the inner wall of the shell, and the buzzer is electrically connected to the outer wall of the circuit board through a wire, and the outer wall of the circuit board is electrically connected to an indicator light.

[0012] As a preferred technical solution of a smoke sensor with high fire monitoring and detection accuracy of the utility model, a magnetic ring is slidably connected to the inner wall of the shell, and a baffle extending to the inside of the shell is fixedly connected to the bottom end of the magnetic ring.

[0016] In summary, the utility model mainly has the following beneficial effects:

[0017] 1. The utility model pushes the rotating plate so that the convex block no longer blocks the limit block, so that the worker can pull the shell downward to separate the shell from the top plate, so that the worker does not need to keep his head up to operate when repairing the smoke sensor, which improves the convenience of smoke sensor repair work, avoids foreign matter from entering the worker's eyes, and reduces labor intensity;

[0018] 2. The utility model attracts the magnetic ring to the iron ring, thereby driving the baffle, so that the baffle blocks the battery to prevent the battery from slipping out of the shell. After the shell is separated from the top plate, the magnetic ring and the iron ring are separated. At this time, the reset spring pushes the baffle to reset, so that the baffle no longer blocks the battery. Compared with the traditional smoke sensor, which needs to disassemble the shell to replace the battery, the technical solution makes it more convenient and quick to replace the battery when it needs to be replaced.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0027] The following describes an embodiment of the utility model based on its overall structure.

[0028] A smoke sensor with high fire monitoring detection accuracy, such as Figures 1 to 4As shown, it includes a mounting base 1, and a sensing body 2 is arranged at the bottom end of the mounting base 1;

[0029] The mounting base 1 includes a top plate 101, which is fixedly connected to the roof by bolts. Two groups of brackets 102 are fixedly connected to the bottom end of the top plate 101. The inner wall of each group of brackets 102 is rotatably connected to a group of rotating plates 103. The side walls of each group of rotating plates 103 are fixedly connected to a group of protrusions 104. The rotating plates 103 are provided with torsion springs at the connection with the brackets 102.

[0030] The sensing body 2 includes a shell 201 , and two groups of limit blocks 210 are fixedly connected to the side walls of the shell 201 . Each group of limit blocks 210 is slidably connected to the inner wall of a group of brackets 102 , and the outer wall of the limit block 210 abuts against the outer wall of a group of protrusions 104 .

[0031] The top plate 101 is fixed to the ceiling by bolts, and then the housing 201 is held and pushed to fit the housing 201 with the top plate 101. During this process, the limit block 210 slides into the inside of the bracket 102 driven by the housing 201, so that the limit block 210 contacts the protrusion 104. The protrusion 104 is pushed by the limit block 210. At this time, the protrusion 104 drives the rotating plate 103 to flip, so that the rotating plate 103 torsions the torsion spring. After the limit block 210 completely slides over the protrusion 104, the torsion spring pushes the rotating plate 103 to return to its original position. At this time, the protrusion 104 is returned to its original position driven by the rotating plate 103, so that the limit block 210 Block 210 is blocked by protrusion 104 and cannot slide out from the inside of bracket 102, thereby completing the installation of smoke sensor. During maintenance, the rotating plate 103 is pushed to make the rotating plate 103 twist the torsion spring, and the protrusion 104 is flipped under the drive of the rotating plate 103, so that there is no contact between the protrusion 104 and the limit block 210, and then the shell 201 is pulled downward, so that the shell 201 drives the limit block 210 to slide to the outside of the bracket 102, and then the rotating plate 103 is released, so that the torsion spring pushes the rotating plate 103 to reset, so that the shell 201 can be quickly separated from the top plate 101 during maintenance, which is convenient for maintenance.

[0032] Please refer to Figures 1 to 4The inner wall of the shell 201 is fixedly connected with a circuit board 202, the outer wall of the circuit board 202 is electrically connected with a sensor body 203, the inner wall of the shell 201 is fixedly connected with a buzzer 204, the buzzer 204 is electrically connected to the outer wall of the circuit board 202 through a wire, the outer wall of the circuit board 202 is electrically connected with an indicator light 205, the inner wall of the shell 201 is slidably connected with a magnetic ring, the bottom end of the magnetic ring is fixedly connected with a baffle 208 extending to the inside of the shell 201, the inner wall of the shell 201 is slidably connected with a battery 206, the electrodes of the battery 206 are electrically connected to the circuit board 202 through a conductive sheet, the outer wall of the battery 206 is slidably attached to the side wall of the baffle 208, the side wall of the baffle 208 is fixedly connected with a return spring 209, the end of the return spring 209 is fixedly connected to the inner wall of the shell 201, the bottom end of the top plate 101 is fixedly connected with an iron ring 105, and the iron ring 105 is magnetically adsorbed on the top of the magnetic ring 207.

[0033] When the battery 206 needs to be replaced, the shell 201 is removed from the top plate 101 through the above-mentioned operation. At this time, the top plate 101 is separated from the shell 201, so that the magnetic circle 207 and the iron ring 105 are no longer adsorbed together. At this time, the return spring 209 pushes the baffle 208 to return to its original position, so that the baffle 208 cannot block the battery 206. Then the shell 201 is tilted to make the battery 206 slide out from the inside of the shell 201, and then the new battery 206 is pushed into the inside of the shell 201, and then the shell 201 and the top plate 101 are installed together. At this time, the magnetic circle 207 and the iron ring 105 are close to each other, and the magnetic force of the magnetic circle 207 makes the magnetic circle 207 adsorbed on the iron ring 105. At this time, the magnetic circle 207 drives the baffle 208 to slide and compresses the return spring 209. At this time, the baffle 208 blocks the battery 206, so that the battery 206 cannot slide out from the inside of the shell 201.

[0034] When in use, by pushing the rotating plate 103, the protrusion 104 no longer blocks the limit block 210, so that the worker can pull the shell 201 downward to separate the shell 201 from the top plate 101, so that the worker does not need to keep his head tilted up to operate when repairing the smoke sensor, which improves the convenience of smoke sensor repair work, avoids foreign matter from entering the workers' eyes, and reduces labor intensity. The parts not involved in the device are the same as the prior art or can be implemented using the prior art.
