Description

Technical Field

[0001] This utility model relates to the field of dust removal tools, and in particular to a portable smoke alarm dust removal device. Background Technology

[0002] Smoke detectors are crucial for early fire warning. Accumulation of dust, cobwebs, and other contaminants can easily lead to false alarms or decreased sensitivity, seriously impacting fire safety. Currently, common maintenance methods include traditional manual cleaning and ordinary compressed air purging, but both have significant drawbacks. Traditional manual cleaning requires maintenance personnel to use ladders or elevated platforms, which carries a risk of fall. Using brushes, air blowers, or cotton swabs for cleaning and maintenance in large areas with hundreds or thousands of detectors, such as winery workshops and warehouses, is extremely labor-intensive and ineffective. Brushes can easily trap dust deep within the detectors, and air blowers, due to their low airflow and insufficient pressure, are ineffective at removing stubborn dirt. Furthermore, using brushes in flammable and explosive environments such as bottling workshops and wine cellars can cause safety accidents due to static electricity. Another method is purging with ordinary compressed air. While this provides a certain pressure, it suffers from uncontrollable pressure, and excessive pressure can easily damage the delicate electronic and optical components inside the alarm. Operationally, the heavy air hose is difficult to drag, resulting in poor control precision during high-altitude work. Furthermore, the air source depends on a compressed air pipeline network, making it unusable in areas without such a network. Additionally, ordinary air guns have concentrated airflow and a limited purging area, making it difficult to cover the complex internal structure of the detector. Therefore, there is an urgent need for a device specifically designed for cleaning smoke alarms to overcome the shortcomings of existing technologies. Utility Model Content

[0003] The purpose of this utility model is to provide a portable smoke alarm dust removal device that addresses the above-mentioned problems. This device features convenient operation, adjustable blowing pressure, and efficient and thorough cleaning, thereby solving problems such as high risks associated with high-altitude operations, incomplete cleaning, and potential equipment damage.

[0004] This utility model is achieved through the following solution: A portable smoke detector dust removal device includes a pneumatic device and a nozzle. The pneumatic device is equipped with a first regulating valve at its air outlet for coarse adjustment of the air volume. The first regulating valve is connected to a sleeve, and the end of the sleeve is connected to the nozzle via a universal metal hose. The nozzle is detachably connected at the end of the universal metal hose. The gas output from the pneumatic device passes sequentially through the first regulating valve, the sleeve, and the universal metal hose before being sprayed out by the nozzle.

[0005] Furthermore, a first extension pipe is provided between the first regulating valve and the sleeve.

[0006] Furthermore, a second regulating valve is provided at one end of the sleeve near the first extension tube. The second regulating valve is a handle switch regulating valve, which is used for hand-held fine adjustment or opening and closing of the gas volume.

[0007] Furthermore, the pneumatic device is a high-pressure air tank, and the first regulating valve is a main regulating valve. A visual pressure gauge is installed on the main regulating valve to display the adjusted air pressure value in real time.

[0008] Furthermore, the visual pressure gauge is connected to the first regulating valve via a second extension tube.

[0009] Furthermore, the sleeve is composed of multiple pipe sections that are detachably connected and assembled through threaded interfaces at both ends, and the overall length can be adjusted by increasing or decreasing the number of pipe sections.

[0010] Furthermore, the sleeve is a telescopic structure, and its length can be adjusted by sliding and locking different numbers of tube sections.

[0011] Furthermore, the nozzle is replaceable and is equipped with at least two different outlet shapes, including needle nozzles or flat nozzles.

[0012] Furthermore, the universal metal flexible hose is made of stainless steel corrugated pipe.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. With the help of replaceable special nozzles and multiple regulating valves to adjust the air pressure, it can clean complex structures without dead angles. The adjustable pressure function ensures that the blowing force is just right, effectively avoiding damage to internal precision components due to excessive pressure.

[0014] 2. The use of multi-section detachable or telescopic sleeves and universal metal hoses allows operators to flexibly adjust the working length and purging angle on the ground, avoiding the risks of working at height.

[0015] 3. The integrated handheld design allows for immediate use of the gas cylinder without relying on an external gas source, enabling flexible use in any location requiring maintenance. Attached Figure Description

[0021] like Figures 1-2 As shown, a portable smoke alarm dust removal device is provided, including a pneumatic device and a nozzle 7. The pneumatic device is preferably a portable high-pressure air tank 1. The air tank 1 is provided with a first regulating valve 2 at the air outlet for coarse adjustment of the air volume. Preferably, the first regulating valve 2 is a main regulating valve, which is manually controlled. A first extension tube 21 is provided between the main regulating valve and the sleeve 4; a second regulating valve 5 is provided at one end of the sleeve 4 near the first extension tube 21. The second regulating valve 5 is preferably a handle-operated regulating valve, installed on the handheld main rod. Its interior is hollow for wiring and fixing air circuit components, and includes a pressure regulating knob. The bottom end of the telescopic sleeve 4 is detachably installed at the top of the handheld main rod via a threaded connection. The user can finely adjust or turn on / off the air volume by holding the handle, and control the output pressure by rotating the pressure regulating knob, thereby achieving stepless or stepped adjustment of the blowing pressure, ensuring that the pressure can blow away dust without damaging the detector.

[0022] The main regulating valve is also equipped with a visual pressure gauge 3, which is connected to the first regulating valve 2 via a second extension pipe 22 for real-time display of the regulating air pressure value; both the first extension pipe 21 and the second extension pipe 22 are threaded hoses; the high-pressure gas tank 1, the main regulating valve, the handle switch regulating valve, and the entire air pipeline form a pressure-adjustable air blowing unit.

[0023] The end of the sleeve 4 is connected to the nozzle 7 by a universal metal hose 6, preferably a stainless steel corrugated pipe, which has multi-directional adjustment capability and can maintain its shape at a certain angle; the nozzle interface 73 and the end interface 61 of the universal metal hose 6 are threaded together, thus... Figures 3-4 As shown, the nozzle 7 can be replaced with a needle-shaped nozzle 71 or a flat nozzle 72, which are suitable for point-like concentrated purging or area-like diffusion purging, respectively.

[0024] The sleeve 4 is a multi-section tube body, employing a multi-section sleeve design. Its overall length is adjusted via rotation or a locking mechanism. Preferably, it is detachably assembled via threaded interfaces 41 at both ends. The overall length is adjusted by increasing or decreasing the number of tube sections. Furthermore, sealing kits can be added at the interfaces to improve sealing. In another embodiment, the sleeve 4 is a telescopic multi-section tube body. Different lengths of the tube body are adjusted by sliding and using locking elements. This structure can incorporate a high-pressure hose, which is connected to a handle switch regulating valve. Preferably, it employs a three-section telescopic sleeve design, with the diameter increasing sequentially from the inside to the outside. The adjustment range can extend from 1.5 meters to 3 meters.

[0025] The gas canister 1 can also be equipped with a carrying kit, such as a waist belt and a shoulder strap, to make it easy to carry the gas canister 1 with you.

[0026] The gas output from the pneumatic device passes sequentially through the main regulating valve, the first extension pipe 21, the handle switch regulating valve, the sleeve 4, and the universal metal hose 6 before being sprayed out from the nozzle 7.

[0027] Work Process: Assemble the sleeve 4 according to the site conditions, select and install the appropriate nozzle 7, such as using a flat nozzle 72 for large areas and a needle nozzle for gaps; then turn on the main valve of the gas tank 1, and slowly adjust the main regulating valve while observing the visual pressure gauge to preset the main air pressure within a safe and effective range; the maintenance personnel hold the sleeve 4 equipped with the handle switch regulating valve and extend the nozzle 7 near the smoke inlet of the smoke alarm to be cleaned. The direction of the nozzle 7 can be easily adjusted by bending the universal metal hose 6. Slightly open the handle switch regulating valve, and airflow will spray out for purging; the valve can be adjusted in real time as needed to control the instantaneous air volume. For complex structures, different nozzles 7 can be switched to achieve the best cleaning effect.

[0028] This embodiment utilizes a universal metal hose 6 connected between the sleeve 4 and the nozzle 7 for universal adjustment. The sleeve 4 is detachable and can be assembled or extended and adjusted in length. The nozzle 7 can be replaced for purging. Two regulating valves form a multi-stage air volume regulation system for overall pressure regulation and real-time control. This achieves safe and efficient cleaning of the smoke alarm without damage, effectively overcoming the shortcomings of traditional cleaning methods such as low efficiency, high risk, incomplete cleaning, and uncontrollable pressure and inconvenient operation of ordinary compressed air purging.
