Description

Technical Field

[0001] This utility model relates to the technical field of fire smoke alarm devices, specifically to a fire smoke alarm device with a dustproof device. Background Technology

[0002] Smoke detectors, also known as smoke sensors, prevent fires by monitoring the concentration of smoke. The infrared beam from the infrared emitter in a smoke detector is scattered by smoke particles. The intensity of the scattered light is proportional to the smoke concentration, so the intensity of the infrared beam received by the photosensitive tube changes. Inside the smoke detector, there is a set of infrared emitting and receiving photocells. When there is no smoke in the environment, the receiving tube does not receive the infrared light emitted by the emitter, and the subsequent sampling circuit shows no change in electrical signal. When there is smoke, smoke particles enter the smoke detector, causing the infrared light emitted by the emitter to scatter. The intensity of the scattered infrared light has a linear relationship with the smoke concentration, causing a change in the subsequent sampling circuit. The alarm's built-in main control chip judges these changes to determine if a fire has occurred. Once a fire is detected, the alarm sends a fire alarm signal and activates the buzzer. Smoke detectors can automatically monitor for fires when people are not present, ensuring personal safety, and are widely used in various fields.

[0003] Existing smoke detectors have certain drawbacks. After a period of use, the buzzer of a smoke detector on the market becomes covered with dust, affecting its alarm sound and posing a significant security management vulnerability. Furthermore, the dustproof mesh used in smoke detectors is not easy to remove, which increases maintenance costs. Therefore, it is particularly important to improve existing fire smoke alarm devices and design a new type of fire smoke alarm device with a dustproof device to solve the above-mentioned technical defects and improve the overall practicality of fire smoke alarm devices. Utility Model Content

[0004] The purpose of this utility model is to provide a fire smoke alarm device with a dustproof device. When the main body of the alarm is in use, the dustproof cover can prevent dust from contacting the main body of the alarm and affecting its alarm sound. When too much dust accumulates on the surface of the dustproof cover, the inside of the dustproof cover can be effectively cleaned, and the dust in the air pores inside the dustproof cover can be removed to prevent the dust from clogging the dustproof cover and affecting the alarm sound of the main body of the alarm, thus ensuring the normal use of the smoke alarm device and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fire smoke alarm device with a dustproof device includes an alarm body, a dustproof cover at the bottom of the alarm body, a cleaning component at the bottom of the alarm body and inside the dustproof cover, and two sets of connecting components at the top of the dustproof cover.

[0007] The cleaning assembly is used to clean the inside of the dust cover. The cleaning assembly consists of an inner toothed ring, a connecting frame, a rotating frame, multiple sets of rotating rods, multiple sets of connecting strips, and multiple sets of cleaning brushes. The inner toothed ring is located at the bottom of the alarm body and inside the dust cover. The connecting frame is located inside the inner toothed ring. The rotating frame is fixedly connected to the bottom of the connecting frame. The multiple sets of rotating rods are rotatably connected to the four sides inside the rotating frame. The two sets of connecting strips are located at both ends of the rotating rods. The cleaning brushes are fixedly connected to the outside of the connecting strips.

[0008] The connecting component is used to connect the dust cover to the alarm body.

[0009] As a preferred embodiment of this utility model, a connecting ring is fixedly connected to one end of the internal toothed ring near the alarm body, and the connecting ring is fixedly connected to the alarm body.

[0010] In a preferred embodiment of this utility model, the connecting frame and the connecting ring are rotatably connected, and a drive motor is provided inside the connecting ring, with the drive end of the drive motor fixedly connected to the connecting frame.

[0011] As a preferred embodiment of this utility model, drive gears are rotatably connected to all four sides of the inside of the connecting frame. The drive gears are meshed with the internal gear ring, and the internal gear ring is fixedly connected to the rotating rod.

[0012] As a preferred embodiment of this utility model, the connecting strip is connected to the rotating rod by fixing bolts, and a brush is fixedly connected to the bottom of the rotating frame.

[0013] As a preferred embodiment of this utility model, the connecting assembly consists of a sliding block, two sets of snap-fit ​​rods, a sliding rod, and a compression spring. The sliding block is slidably connected to the top of the inside of the dust cover. Both sets of snap-fit ​​rods are fixedly connected to the outside of the sliding block. The sliding rod is located inside the sliding block and fixedly connected to the top of the inside of the dust cover.

[0014] As a preferred embodiment of this utility model, two sets of mounting blocks are fixedly connected to one end of the alarm body near the dust cover. The mounting blocks have mounting grooves inside, and the mounting blocks are connected to the snap-fit ​​rods through the mounting grooves.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, through the design of the cleaning components and dust cover, when the alarm body is in use, the dust cover can prevent dust from contacting the alarm body and affecting its alarm sound. When too much dust accumulates on the surface of the dust cover, the connecting frame rotates, causing multiple sets of rotating rods to rotate and shift around the center of the rotating frame. This causes multiple sets of cleaning brushes to shift. When the connecting frame rotates, it drives the drive gear to shift. The drive gear meshes with the internal gear ring, causing the drive gear to rotate, which in turn drives the rotating rods to rotate. This causes the cleaning brushes to rotate and shift around the rotating rods, thereby effectively cleaning the inside of the dust cover and removing dust from the air pores inside the dust cover. This prevents dust from clogging the dust cover and affecting the alarm sound of the alarm body, ensuring the normal use of the smoke alarm device.

[0017] 2. In this utility model, the design of the connecting component makes it easy to install the dust cover when it needs to be installed, thus increasing the efficiency of dust cover installation. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example:

[0027] Please see Figures 1-6 This utility model provides a technical solution:

[0028] A fire smoke alarm device with a dustproof device includes an alarm body 1, a dust cover 2 at the bottom of the alarm body 1, a cleaning component 3 at the bottom of the alarm body 1 and inside the dust cover 2, and two sets of connecting components 4 at the top of the dust cover 2.

[0029] The cleaning assembly 3 is used to clean the inside of the dust cover 2. The cleaning assembly 3 consists of an inner toothed ring 5, a connecting frame 6, a rotating frame 7, multiple sets of rotating rods 8, multiple sets of connecting strips 9, and multiple sets of cleaning brushes 10. The inner toothed ring 5 is located at the bottom of the alarm body 1 and inside the dust cover 2. The connecting frame 6 is located inside the inner toothed ring 5. The rotating frame 7 is fixedly connected to the bottom of the connecting frame 6. Multiple sets of rotating rods 8 are rotatably connected to the four sides inside the rotating frame 7. Two sets of connecting strips 9 are located at the two ends of the rotating rods 8. The cleaning brushes 10 are fixedly connected to the outside of the connecting strips 9.

[0030] The connecting component 4 is used to connect the dust cover 2 to the alarm body 1.

[0031] Furthermore, a connecting ring 11 is fixedly connected to one end of the internal toothed ring 5 near the alarm body 1. The connecting ring 11 is fixedly connected to the alarm body 1, and the internal toothed ring 5 is fixedly connected to the connecting ring 11 so that the internal toothed ring 5 can be connected to the alarm body 1 through the connecting ring 11.

[0032] The connecting frame 6 and the connecting ring 11 are rotatably connected. The connecting ring 11 is equipped with a drive motor. The drive end of the drive motor is fixedly connected to the connecting frame 6. When the drive motor is started, the connecting frame 6 is rotated, which causes the rotating frame 7 to rotate. This causes multiple sets of rotating rods 8 to rotate and displace around the center of the rotating frame 7, which in turn causes multiple sets of cleaning brushes 10 to move.

[0033] Secondly, drive gears 12 are rotatably connected to all four sides of the inside of the connecting frame 6. The drive gears 12 are meshed with the internal gear ring 5, and the internal gear ring 5 is fixedly connected to the rotating rod 8. When the connecting frame 6 rotates, it drives the drive gears 12 to move. The meshing connection between the drive gears 12 and the internal gear ring 5 causes the drive gears 12 to rotate, which in turn drives the rotating rod 8 to rotate. This causes the cleaning brush 10 to rotate and move around the rotating rod 8 as the center, thereby effectively cleaning the inside of the dust cover 2 and removing the dust from the air pores inside the dust cover 2. This prevents the dust from clogging the dust cover 2 and affecting the alarm sound of the alarm body 1, ensuring the normal use of the smoke alarm device.

[0034] Furthermore, the connecting strip 9 is connected to the rotating rod 8 by the fixing bolt 13. The bottom of the rotating frame 7 is fixedly connected to the brush 14. The connecting strip 9 is connected to the rotating rod 8, and the fixing bolt 13 is connected to the connecting strip 9, so that the connecting strip 9 can be installed inside the rotating rod 8. The connecting strip 9 and the rotating rod 8 are detachably connected, so that the cleaning brush 10 can be easily replaced when it is worn too much.

[0035] Furthermore, the connecting assembly 4 consists of a sliding block 15, two sets of snap-fit ​​rods 16, a sliding rod 17, and a compression spring 18. The sliding block 15 is slidably connected to the top inside the dust cover 2. Both sets of snap-fit ​​rods 16 are fixedly connected to the outside of the sliding block 15. The sliding rod 17 is located inside the sliding block 15 and is fixedly connected to the top inside the dust cover 2. The compression spring 18 is sleeved on the outside of the sliding rod 17 and fixedly connected to the outside of the sliding block 15. When the dust cover 2 needs to be installed, the connecting assembly 4 can facilitate the installation of the dust cover 2, increasing the efficiency of the dust cover 2 installation.

[0036] Furthermore, two sets of mounting blocks 19 are fixedly connected to one end of the alarm body 1 near the dust cover 2. The mounting blocks 19 have mounting grooves inside, and the mounting blocks 19 are connected to the locking rods 16 through the mounting grooves, connecting the dust cover 2 to the alarm body 1. This causes the mounting blocks 19 to move into the interior of the dust cover 2. The compression spring 18 drives the sliding block 15 to move, causing the two sets of locking rods 16 to move into the interior of the mounting grooves and make a limiting connection with the mounting blocks 19, so that the dust cover 2 can be installed at the bottom of the alarm body 1.

[0037] In this embodiment, the specific implementation scenario is as follows: In actual use, the dust cover 2 is connected to the alarm body 1, causing the mounting block 19 to move into the interior of the dust cover 2. The compression spring 18 drives the sliding block 15 to move, causing the two sets of locking rods 16 to move. The locking rods 16 are moved into the interior of the mounting groove and connected to the mounting block 19, allowing the dust cover 2 to be installed. The dust cover 2 is installed at the bottom of the alarm body 1. The drive motor is started, causing the connecting frame 6 to rotate, causing the rotating frame 7 to rotate. This causes multiple sets of rotating rods 8 to rotate around the center of the rotating frame 7, allowing multiple cleaning rods to move. The brush 10 is displaced, and when the connecting frame 6 rotates, it drives the drive gear 12 to move. The drive gear 12 meshes with the internal gear ring 5, causing the drive gear 12 to rotate, which in turn drives the rotating rod 8 to rotate. This causes the cleaning brush 10 to rotate and move around the rotating rod 8 as the center, thereby effectively cleaning the inside of the dust cover 2 and removing dust from the air pores inside the dust cover 2. This prevents dust from clogging the dust cover 2 and affecting the alarm sound of the alarm body 1, ensuring the normal use of the smoke alarm device. Compared with existing fire smoke alarm devices, this utility model improves the overall practicality of the fire smoke alarm device through its design.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
