Description

Technical Field

[0001] This utility model belongs to the technical field of air conditioner outdoor unit cleaning devices, specifically relating to an air cleaning gun for air conditioner outdoor unit maintenance. Background Technology

[0002] Over time, air conditioner outdoor units accumulate a large amount of dust inside. Therefore, it is necessary to remove this accumulated dust during the maintenance and repair of the outdoor unit. In actual cleaning, technicians often use an air pump with an air gun. This method inevitably generates a lot of dust, affecting the technician's vision. Furthermore, if the dust is inhaled, it can affect the technician's health. Another method is to use a vacuum cleaner. However, to ensure effective suction, the suction inlet needs to be aligned perfectly with the surface of the object carrying the dust. If it cannot be aligned perfectly, the suction effect will be greatly reduced. Therefore, the effectiveness of both methods needs improvement. To address this, we propose an air cleaning gun for air conditioner outdoor unit maintenance, which can effectively clean the dust accumulated inside the outdoor unit while avoiding dust generation. Utility Model Content

[0003] The purpose of this invention is to provide an air cleaning gun for the maintenance of air conditioner outdoor units, which can effectively clean the dust accumulated inside the air conditioner outdoor unit while avoiding dust generation.

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figure 1-4 As shown, an air cleaning gun for the maintenance of an air conditioner outdoor unit includes a mounting block 1. An air outlet pipe 2 is provided in the middle of the mounting block 1. An umbrella-shaped dust collection component 3 is fitted on the air outlet pipe 2. The dust collection component 3 includes a collection ring groove 301 fitted at the root of the air outlet pipe 2. A plurality of carbon steel strips 302 are provided on the collection ring groove 301. A connecting ring 303 is provided at the end of the plurality of carbon steel strips 302. A carbon steel ring 304 is movably connected to the connecting ring 303. The carbon steel ring 304 is open. A limiting device is provided at the opening of the carbon steel ring 304. A leather cloth 305 is provided on the carbon steel strips 302.

[0024] In actual use, the mounting block 1 is used to support the air outlet pipe 2 and the dust collection component 3; the carbon steel strip 302 and the carbon steel ring 304 are made of carbon steel, which can be folded freely within a certain range. They are tough and can also support the leather cloth 305, making it easier for the dust collection component 3 to adapt to the irregular structure inside the air conditioner outdoor unit, greatly improving the dust collection effect.

[0025] Preferably, the mounting block 1 is provided with a fan 4, the upper part of the fan 4 is provided with a dust collection box 5, the root of the air outlet pipe 2 is connected to the air outlet of the fan 4, the air inlet of the fan 4 is connected to an air inlet pipe 6, and one end of the air inlet pipe 6 is connected to one end of the dust collection box 5.

[0026] In actual use, after the fan 4 starts working, it directly blows air into the air inlet pipe 6. The air blown out from the end of the air inlet pipe 6 blows away the dust inside the outdoor unit of the air conditioner. At the same time, the air inlet of the fan 4 starts to draw air from the collection ring groove 301 through the air inlet pipe 6, making the inside of the collection ring groove 301 a negative pressure mechanism. The dust blown away from the outdoor unit of the air conditioner enters the collection ring groove 301 through the collection cover formed by the leather cloth 305, thus collecting the dust. In the end, dust is blown out and collected at the same time, avoiding dust pollution. While ensuring dust removal, it also ensures the health of maintenance personnel.

[0027] Preferably, a guide pipe 7 is connected through to the other side of the ash collection box 5, and the end of the guide pipe 7 is connected through to the collection ring groove 301.

[0028] It should be noted that the dust inside the collection groove 301 enters the dust collection box 5 through the dust guide pipe 7 and is collected by the dust collection box 5.

[0029] Preferably, the ash collection box 5 is provided with two filter plates 8 inside, and the end of the air inlet pipe 6 is provided with a filter 9. The air inlet pipe 6 also draws in air from the outside through the filter 9.

[0030] In actual use, the dust collection box 5 has two filter plates 8 inside, which can filter dust and ensure that dust will not enter the fan 4 through the air inlet pipe 6, thus improving the service life of the equipment.

[0031] Preferably, the sidewall of the collecting groove 301 is mounted on the mounting block 1 by a reinforcing rod, the end of the air outlet pipe 2 is rounded, and the opening at the end of the air outlet pipe 2 is smaller than the inner diameter of the air outlet pipe 2.

[0032] In actual use, because the opening at the end of the air outlet pipe 2 is smaller than the inner diameter of the air outlet pipe 2, the end of the air outlet pipe 2 can pressurize the blown air, which greatly improves the dust cleaning effect.

[0033] Preferably, the bottom of the mounting block 1 is provided with a handle 10, and a push switch 11 is provided on the handle 10. The push switch 11 controls whether the fan 4 is powered on.

[0034] In actual use, hold the handle 10, press the push switch 11, the fan 4 starts, and the equipment starts working. The circuit connection here is common knowledge and will not be described in detail here.

[0035] Preferably, the limiting device includes a limiting ring 12 disposed at one end of the carbon steel ring 304, the other end of the telescopic carbon steel ring 304 passing through the limiting ring 12, and a limiting bolt 13 threadedly connected to the limiting ring 12.

[0036] By adjusting the carbon steel ring 304, the diameter of the opening at the end of the dust collection hood formed by the leather cloth 305 can be adjusted, making it more suitable for the irregular structure inside the air conditioner outdoor unit.

[0037] Preferably, a lid 14 is hinged to the ash collection box 5, and a positioning pin is provided between the lid 14 and the ash collection box 5 to limit the opening and closing of the lid 14. The lid 14 is opened periodically to clean the ash collection box 5.

[0038] The working principle of this utility model is as follows: First, hold the handle 10 and press the push switch 11. The fan 4 starts and the equipment begins to work. After the fan 4 starts working, it directly blows air into the air inlet pipe 6. The air blown out from the end of the air inlet pipe 6 blows away the dust inside the air conditioner outdoor unit. At the same time, the air inlet of the fan 4 starts to draw air from the collection ring groove 301 through the air inlet pipe 6, making the inside of the collection ring groove 301 a negative pressure mechanism. The dust blown away from the air conditioner outdoor unit enters the collection ring groove 301 through the collection cover formed by the leather cloth 305. The dust inside the collection ring groove 301 enters the dust collection box 5 through the dust guide pipe 7 and is collected by the dust collection box 5. The carbon steel strip 302 and the carbon steel ring 304 are made of carbon steel, which can be folded at will within a certain range. They are tough and can also support the leather cloth 305, making the dust collection component 3 more convenient to adapt to the irregular structure inside the air conditioner outdoor unit.

[0039] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
