Description

Technical Field

[0001] The utility model belongs to the technical field of fire detectors, and more specifically relates to a fire detector which is easy to clean. Background Art

[0002] In the field of fire detectors, smoke alarms are the most widely used tools. Smoke alarms, also known as smoke sensors, prevent fires by monitoring the concentration of smoke. Ion smoke sensors are used internally. Ion smoke sensors are technologically advanced, stable and reliable sensors that are widely used in various fire alarm systems. Their performance is far superior to gas-sensitive resistor fire alarms.

[0003] Traditional smoke fire alarms are installed on the ceiling of the room. Due to the high installation position, they are difficult to clean. After long-term use, dust will block the detection port of the alarm. In order to avoid affecting the normal alarm of the detector, the operator needs to climb up to wipe it. However, this method of climbing up to clean is often dangerous and easy to cause safety hazards. Therefore, a fire detector that is easy to clean is proposed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a fire detector which is easy to clean, and can realize the convenient cleaning and use of the smoke fire detector without the need for height-ascending treatment, which is more convenient and quick.

[0005] The utility model discloses a fire detector which is easy to clean, comprising a fixing seat, a smoke alarm, a fixing sleeve, a movable sleeve, a brush ring and a pull rod; the smoke alarm is fixedly mounted on the lower end surface of the fixing seat, and a detection port is arranged at the lower end of the smoke alarm; the fixing sleeve is fixedly mounted on the lower end surface of the fixing seat, the movable sleeve is movably sleeved in the fixing sleeve, the brush ring is fixedly mounted on the inner wall of the movable sleeve, and the brush ring abuts against the detection port; the pull rod is detachably connected to the movable sleeve, and the movable sleeve and the brush ring are driven to move by pulling the pull rod.

[0006] As a further improvement of the utility model, a spring is fixedly mounted on the lower end surface of the fixing seat, and the other end of the spring is connected to the movable sleeve.

[0007] As a further improvement of the utility model, a limiting sleeve is arranged on the inner wall of the fixed sleeve, and the spring is sleeved in the limiting sleeve.

[0008] As a further improvement of the utility model, a hanging ear is arranged on the lower end surface of the movable sleeve, and a hook is arranged on the upper end of the pull rod; the hook is inserted into the hanging ear.

[0009] As a further improvement of the utility model, a through hole is provided on the side wall of the movable sleeve.

[0010] Compared with the prior art, the advantages of the present invention are:

[0011] 1. The utility model can drive the movable sleeve to move up and down by pulling the pull rod, thereby driving the brush ring to move up and down, so as to clean the detection port of the smoke alarm and avoid the problem of dust falling and affecting the sensitivity of the alarm. At the same time, by pulling the pull rod, there is no need to perform high-altitude operations, which is safer.

[0012] 2. The utility model is provided with a spring. When the pull rod pulls the movable sleeve, the spring can be stretched. The elastic force of the spring can drive the movable sleeve to reset. The operator only needs to pull down the pull rod and then release the pull rod to complete the cleaning of the smoke alarm.

[0013] 3. The utility model facilitates the connection between the pull rod and the movable sleeve through the cooperation of the hanging ear and the pull rod hook. When cleaning is not needed, it is only necessary to remove the hook from the hanging ear to avoid the interference of the pull rod with the use of the room. BRIEF DESCRIPTION OF THE DRAWINGS
