Description

Technical Field

[0001] The utility model relates to the technical field of smoke alarm maintenance, in particular to a cleaning device for an infrared smoke alarm. Background Art

[0002] Infrared smoke alarms are important safety devices used to monitor smoke in the environment, sound the alarm when smoke is detected, and detect fire risks. They utilize infrared technology. When smoke enters the alarm, smoke particles scatter infrared light, which is picked up by the detector and triggers the alarm. However, over time and with use, dust accumulates inside the infrared smoke alarm, causing detector performance to deteriorate and even lead to false fire alarms or dust malfunctions. Cleaning can effectively remove accumulated dust and dirt from the detector, restoring its sensitivity and accuracy. Cleaning methods can include using a soft brush, a clean rag, a vacuum cleaner, or tools like a hair dryer or air canister to gently remove dust. After cleaning, reinstall the cover or casing on the smoke alarm according to the manufacturer's instructions and reconnect the power supply to ensure that the equipment is working properly. However, when using soft brushes, rags and other tools to dust off the dust, you also need to use a vacuum cleaner to assist in removing dust from the surface of the infrared smoke alarm. Because infrared smoke alarms are mostly installed high on the wall or the top of the roof, climbing the ladder itself carries the risk of falling, slipping, etc. If you carry a vacuum cleaner with you at the same time, it may increase the difficulty and risk of operation, especially when cleaning high-place smoke alarms, which is more likely to cause accidents and cause trouble for staff to climb the ladder and clean.

[0018] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-5The utility model provides an embodiment of a cleaning device for an infrared smoke alarm, comprising a cylindrical shell 1 and a right-angle arm 2 arranged on one side of the cylindrical shell 1, the center position of the bottom end of the cylindrical shell 1 is threadedly connected to the bottom of the right-angle arm 2, and a handle 4 is installed on the outer wall of the right-angle arm 2 away from the cylindrical shell 1. An inner air guide tube 7 is fixed to one end of the inner part of the cylindrical shell 1, and a ventilation disk 8 is installed inside the inner air guide tube 7. A main shaft 10 is rotatably installed inside the ventilation disk 8, and a shaft sleeve 801 is fixed at the center position of the top end of the ventilation disk 8, and the top end of the main shaft 10 passes through the outside of the shaft sleeve 801;

[0020] The top of the main shaft 10 extends through the exterior of the cylindrical housing 1 and is equipped with a dust removal structure 12 for sweeping away dust. A turbofan unit 11 is mounted on the surface of the main shaft 10 below the dust removal structure 12. A rotation drive unit 9 for driving the main shaft 10 is mounted at the center of the bottom end of the ventilation disk 8. A motor controller 6 for electrically connecting to the rotation drive unit 9 is mounted at the bottom of the cylindrical housing 1. A control switch 5 electrically connected to the input end of the rotation drive unit 9 is mounted on the outer wall of one side of the right-angle arm 2.

[0021] An outer rubber cover 102 is fixed to the outer edge of the top of the cylindrical housing 1. When a worker lifts the device and it contacts the infrared smoke alarm, the outer rubber cover 102 actively covers the infrared smoke alarm, thereby reducing the amount of dust overflowed by the dust cleaning structure 12 during the dust cleaning process, so that the dust is sucked into the turbine fan unit 11.

[0022] The rotary drive unit 9 includes a protective shell 901 installed at the center of the bottom end of the ventilation disk 8, and a stepper motor 902 installed inside the protective shell 901. The top end of the output shaft of the stepper motor 902 is fixedly connected to the bottom end of the main shaft 10 through a coupling.

[0023] When the rotation drive unit 9 is working, the motor controller 6 controls the stepper motor 902 to rotate, and the stepper motor 902 drives the main shaft 10 and the turbofan unit 11 to rotate. During this process, the protective shell 901 seals and dust-proofs the stepper motor 902.

[0024] The dust cleaning structure 12 includes an inner rubber soft cover 1201 fixed to the top of the main shaft 10, and a sponge pad 1202 fixed to the inner wall of the inner rubber soft cover 1201. The sponge pad 1202 can also be replaced with a felt pad, etc.

[0025] The lower surface of the inner rubber cover 1201 is provided with an arc-shaped hollow groove that completely passes through it. The arc-shaped hollow groove allows dust and air to pass through. The main shaft 10 drives the inner rubber cover 1201 and the sponge pad 1202 to rotate together. The sponge pad 1202 actively contacts the infrared smoke alarm to actively sweep away the dust. During this process, the high-speed rotation of the sponge pad 1202 covers a wider cleaning range of the outer surface of the alarm, ensuring thorough cleaning.

[0026] A conical ash storage cylinder 101 is fixed to the bottom of the cylindrical housing 1. The bottom end of the conical ash storage cylinder 101 extends to the outside of the cylindrical housing 1. An internal thread groove is provided on the inner wall of the bottom end of the conical ash storage cylinder 101.

[0027] An externally threaded head 3 is installed at the bottom opening of the conical ash storage barrel 101. The bottom end of the externally threaded head 3 passes through the outside of the cylindrical shell 1 and is fixedly connected to the bottom of the right-angle arm 2. When dust is sucked into the cylindrical shell 1, the conical ash storage barrel 101 actively stores the dust. Later, the staff can manually twist the handle 4 so that the handle 4 drives the right-angle arm 2 to rotate, thereby separating the externally threaded head 3 from the cylindrical shell 1 thread, and then the dust in the conical ash storage barrel 101 can be poured out, making it convenient for the staff to maintain the cleaning device.

[0028] When the embodiment of the present application is in use, the staff first holds the handle 4 and manually lifts the device through the handle 4 until the dust cleaning structure 12 covers the lower surface of the infrared smoke alarm. Then the staff sends a working signal to the motor controller 6 through the control switch 5, and the motor controller 6 controls the rotation drive unit 9 to work according to the set direction, speed, angle, and response time, and then the rotation drive unit 9 actively drives the main shaft 10, the turbine fan unit 11 and the dust cleaning structure 12 to rotate. At this time, the dust cleaning structure 12 is constantly in contact with the lower surface of the infrared smoke alarm and actively shakes off the dust on the surface of the alarm. Since the turbine fan unit 11 is in the process 1 is also synchronously driven by the rotary drive unit 9 to rotate at high speed, then the turbofan monomer 11 generates negative pressure suction, and the dust shaken off is sent into the interior of the columnar shell 1 by the turbofan monomer 11, thereby completing the purpose of cleaning and sucking dust. The device utilizes an actively rotating cleaning structure 12. The staff only needs to place the cleaning device at the position of the alarm that needs to be cleaned and start the device, which greatly reduces the labor intensity of the operator and improves the cleaning efficiency. In the process, even if the staff climbs the ladder, they can complete the cleaning work of the alarm with one hand, reducing the safety risks of falling, slipping, etc., and providing convenience for the staff's daily maintenance and cleaning of the alarm.

[0029] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
