Technical Field

[0001] This utility model relates to the field of fire alarm devices, specifically a fire alarm device for house rental. Background Technology

[0002] Housing rental refers to a civil legal act in which a landlord rents out a house to a tenant for use, and the tenant pays rent to the landlord. Nowadays, the large flow of people makes the housing rental market very active. Rental houses provide temporary housing for many people. However, because there are many people living in rental houses and a large number and variety of items stored inside, rental houses are prone to fire hazards. Moreover, many items may contain flammable materials. Once a fire occurs, the consequences are unimaginable.

[0003] A fire alarm device is a device that can promptly issue an alarm signal in the early stages of a fire. It is mainly used to alert people to the occurrence of a fire as early as possible so that they can quickly take escape and firefighting measures to minimize the losses caused by the fire. Fire alarm devices on the market are usually composed of detectors and alarm modules. Fire alarm devices mainly determine whether a fire has occurred by detecting the concentration of smoke particles in the air. When the detector detects a fire signal, the alarm module will immediately emit a loud sound and flashing lights to attract people's attention and remind them that a fire has occurred.

[0004] Existing fire alarm devices are generally fixed on the roof or wall. After long-term use, a lot of dust and cobwebs may accumulate around the ventilation holes of the fire alarm device. This dust and cobwebs can clog the ventilation holes, preventing smoke particles in the room from reaching the detectors inside the fire alarm device, ultimately affecting the normal operation of the fire alarm device. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a fire alarm device for rental housing, so as to solve the technical problem that it is difficult to clean the dust and cobwebs accumulated on the ventilation holes of traditional fire alarm devices.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fire alarm device for rental housing, comprising a base and a protective cover. A fixed seat is fixed to one side of the base, and a smoke detector is installed on one side of the fixed seat. The protective assembly includes the fixed seat and the protective cover. The protective cover is fitted onto the outer wall of the fixed seat, and the protective cover and the fixed seat are connected by threads. A limit block is provided on the inner wall of the protective cover, and a support column is movably installed inside the limit block, and the support column penetrates the protective cover. The cleaning assembly includes cleaning fan blades, a support column, a spring, and a rotating disk. The bottom end of the support column is connected to the rotating disk, and multiple sets of cleaning fan blades are installed on the outer wall of the rotating disk. A groove is provided at the bottom of the rotating disk.

[0007] By adopting the above technical solution, the problem of dust and cobwebs accumulating on the ventilation holes of traditional fire alarm devices that are difficult to clean is solved. When it is necessary to clean the dust on the surface of the fire alarm device, the personnel insert a rod into the groove at the bottom of the cleaning component and push it upward, so that the brush on the inner wall of the cleaning fan blade is in close contact with the surface of the protective cover. Then the personnel rotate the rod, so that the cleaning fan blade rotates around the rotating disk. During the rotation of the cleaning fan blade, the brush on the cleaning fan blade cleans the surface of the protective cover. This cleaning method makes it convenient for personnel to stand on the bottom to clean the dust on the surface of the fire alarm device.

[0008] The present invention is further configured such that a sealing cover is connected to the top of the support column, and the inner diameter of the sealing cover is larger than the diameter of the smoke detector.

[0009] By adopting the above technical solution, when personnel clean the dust on the surface of the fire alarm device, the support column moves upward and pushes the sealing cover to completely cover the smoke detector, preventing dust particles from floating into the inside of the smoke detector when personnel clean the exterior of the protective cover, thus avoiding false alarms caused by dust.

[0010] The present invention is further configured such that a connecting block is provided at the bottom end of the sealing cover, and a spring is connected to the bottom end of the connecting block, and one end of the spring is connected to a limiting block.

[0011] By adopting the above technical solution, when personnel use a rod to push the support column upward, the support column drives the connecting block to move upward together, causing the spring to stretch. After the fire alarm device is cleaned, the spring returns to its original position and pushes the support column downward back to its original position.

[0012] The present invention is further configured such that multiple sets of reinforcing blocks are installed inside the protective cover, which can increase the overall strength of the protective cover.

[0013] By adopting the above technical solution, a reinforcing block made of high-strength material is installed inside the protective cover. The reinforcing block enhances the overall strength of the protective cover and prevents cracks from forming due to pressure when cleaning dust from the surface of the protective cover later.

[0014] The present invention is further configured such that a brush is provided on the inner wall of the cleaning fan blade, and when the cleaning fan blade is moved to the highest position, the brush on the cleaning fan blade is in close contact with the surface of the protective cover.

[0015] By adopting the above technical solution, when the support column is moved to its highest point, the inner wall of the cleaning fan blade surrounds the protective cover, and the brush on the inner wall of the cleaning fan blade is in close contact with the protective cover. When the cleaning fan blade rotates, the brush on the cleaning fan blade cleans the dust and cobwebs on the protective cover.

[0016] The present invention is further provided that the bottom end of the rotating disk has a groove, and the inner wall of the groove is equipped with an anti-slip pad.

[0017] By adopting the above technical solution, the groove at the bottom of the rotating disk makes it convenient for personnel to rotate and control the cleaning fan blades with a rod. At the same time, the anti-slip pad installed inside the groove prevents the rod inserted into the groove from slipping.

[0018] The present invention is further configured such that a limiting plate is movably installed inside the rotating disk, and the end of the limiting plate is connected to the bottom end of the support column.

[0019] By adopting the above technical solution, the support column and the rotating disk are connected by a limiting plate. The diameter of the limiting plate is larger than the diameter of the support column, so that the rotating disk limits the limiting plate, thereby enabling the rotating disk to drive the cleaning fan blades to rotate below the support column.

[0020] The present invention is further provided that the top of the protective cover is provided with a ventilation hole, and the bottom of the protective cover is provided with a breathable hole.

[0021] By adopting the above technical solution, multiple ventilation holes and air vents are opened on the surface of the protective cover, allowing the smoke detector to come into contact with the outside air, thereby enabling the smoke detector to accurately detect the concentration of fire smoke in the outside air.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model solves the problem of difficult cleaning of dust and cobwebs accumulated on the ventilation holes of traditional fire alarm devices by setting up a base, protective cover, cleaning fan blades, support column and smoke detector. When it is necessary to clean the dust on the surface of the fire alarm device, the personnel insert a rod into the groove at the bottom of the cleaning component and push it upward, so that the brush on the inner wall of the cleaning fan blade is in close contact with the surface of the protective cover. Then the personnel rotate the rod, so that the cleaning fan blade rotates around the rotating disk. During the rotation of the cleaning fan blade, the brush on the cleaning fan blade cleans the surface of the protective cover. This cleaning method makes it convenient for personnel to stand on the bottom to clean the dust on the surface of the fire alarm device.

[0024] 2. By setting a sealing cover, spring, connecting block and support column, the support column pushes the top of the sealing cover to contact the surface of the fixed seat during the upward movement of the cleaning component, so that the sealing cover covers the smoke detector, isolating the smoke detector from the outside world, and preventing the smoke detector from false alarms caused by the high concentration of dust in the air when the cleaning component cleans the dust on the surface of the protective cover.

The bottom end of the support column 4 is connected to the rotating disk 31, and multiple sets of cleaning fan blades 3 are installed on the outer wall of the rotating disk 31. The bottom of component 31 has a groove 32, which solves the problem of dust and cobwebs accumulating on the ventilation holes of traditional fire alarm devices being difficult to clean. When it is necessary to clean the dust on the surface of the fire alarm device, the personnel insert a rod into the groove 32 at the bottom of the cleaning component and push it upward, so that the brush on the inner wall of the cleaning fan blade 3 is in close contact with the surface of the protective cover 2. Then the personnel rotate the rod, so that the cleaning fan blade 3 rotates around the rotating disk 31. During the rotation of the cleaning fan blade 3, the brush on the cleaning fan blade 3 cleans the surface of the protective cover 2. This cleaning method makes it convenient for personnel to stand on the bottom to clean the dust on the surface of the fire alarm device.

[0034] Please see Figure 4 The top of the support column 4 is connected to a sealing cover 6, and the inner diameter of the sealing cover 6 is larger than the diameter of the smoke detector 5. When personnel clean the dust on the surface of the fire alarm device, the support column 4 moves upward and pushes the sealing cover 6 to completely cover the smoke detector 5, preventing dust particles from floating into the inside of the smoke detector 5 when personnel clean the exterior of the protective cover 2, and avoiding false alarms caused by dust in the smoke detector 5.

[0035] Please see Figure 4 The bottom of the sealing cover 6 is provided with a connecting block 61, and the bottom of the connecting block 61 is connected to a spring 7. One end of the spring 7 is connected to a limiting block 24. When the personnel use a rod to push the support column 4 upward, the support column 4 drives the connecting block 61 to move upward together, so that the spring 7 is stretched. After the fire alarm device is cleaned, the spring 7 resets and pushes the support column 4 downward to return to its original position.

[0036] Please see Figure 5 The protective cover 2 has multiple sets of reinforcing blocks 21 installed inside. The reinforcing blocks 21 can increase the overall strength of the protective cover 2. The reinforcing blocks 21 with high strength material are installed inside the protective cover 2. The reinforcing blocks 21 enhance the overall strength of the protective cover 2 and prevent the protective cover 2 from cracking due to pressure when cleaning the surface dust of the protective cover 2 later.

[0037] Please see Figure 3The inner wall of the cleaning fan blade 3 is equipped with a brush. When the cleaning fan blade 3 moves to the highest position, the brush on the cleaning fan blade 3 is in close contact with the surface of the protective cover 2. When the support column 4 moves to the highest position, the inner wall of the cleaning fan blade 3 surrounds the protective cover 2, and the brush on the inner wall of the cleaning fan blade 3 is in close contact with the protective cover 2. When the cleaning fan blade 3 rotates, the brush on the cleaning fan blade 2 cleans the dust and cobwebs on the protective cover 2.

[0038] Please see Figure 5 The bottom of the rotating disk 31 is provided with a groove 32, and the inner wall of the groove 32 is equipped with an anti-slip pad 8. The groove 32 at the bottom of the rotating disk 31 makes it convenient for personnel to use a rod to rotate and control the cleaning fan blade 3.

The support column 4 and the rotating disk 31 are connected by the limit plate 41. The diameter of the limit plate 41 is larger than the diameter of the support column 4, so that the rotating disk 31 limits the limit plate 41, thereby the rotating disk 31 can drive the cleaning fan blade 3 to rotate below the support column 4.

[0040] Please see Figure 1 The top of the protective cover 2 is provided with ventilation holes 22, and the bottom of the protective cover 2 is provided with ventilation holes 23. Multiple ventilation holes 22 and ventilation holes 23 are provided on the surface of the protective cover 2, so that the smoke detector 5 can come into contact with the outside air, thereby enabling the smoke detector 5 to accurately detect the concentration of fire smoke in the outside air.

[0041] The working principle of this utility model is as follows: First, the protective component is fixed to the base 1 by threaded connection between the protective cover 2 and the fixing seat 11. Then, the base 1 is fixed to the roof wall. When it is necessary to clean the surface dust of the fire alarm device, a person inserts a rod into the groove 32 at the bottom of the cleaning component and pushes it upward. The upward push of the rod causes the entire cleaning component to move upward. The support column 4 in the cleaning component pushes the top of the sealing cover 6 to contact the surface of the fixing seat 11. During the upward movement of the support column 4, the spring 7 extends, and finally the sealing cover 6 covers the top. Above the smoke detector 5, the smoke detector 5 is isolated from the outside world. At the same time, the brush on the inner wall of the cleaning blade 3 is pressed against the surface of the protective cover 2. Then, the operator rotates the rod, so that the cleaning blade 3 rotates around the rotating disk 31. During the rotation of the cleaning blade 3, the brush on the cleaning blade 3 cleans the surface of the protective cover 2. After cleaning is completed, the operator removes the rod from the groove 32 at the bottom of the cleaning component. When the rod is removed from the groove 32, the spring 7 retracts and resets, and at the same time, it drives the sealing cover 6 and the cleaning component to move downwards and reset.
