Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of high-pressure cleaning machines, in particular to a noise reduction structure for high-pressure cleaning machines. Background Art
[0002] A high-pressure cleaning machine refers to a cleaning equipment that uses a high-pressure water conversion device (generally a high-pressure plunger pump) to pressurize water through several stages to a pressure of hundreds of atmospheres, and then shoots it out through a high-pressure water gun.
[0003] The high-pressure cleaner makes a lot of noise when it is running. The existing technology mainly achieves a certain sound insulation effect by setting a sound insulation cotton layer in the air deflector. However, the overall sound insulation effect of this structure is not very good. Secondly, because the inside of the high-pressure cleaner is easy to get water, the sound insulation cotton is easy to mold after being exposed to water for a long time, which makes the inside of the high-pressure cleaner smelly. Finally, the cost of the sound insulation cotton is high, which leads to the high cost of the high-pressure cleaner. Utility Model Content
[0004] The technical solution to be solved by the utility model is to provide a noise reduction structure for a high-pressure cleaning machine. The high-pressure cleaning machine using this noise reduction structure has a better overall sound insulation effect, and because no sound insulation cotton is arranged inside the cleaning machine, it is not easy to mold and stink, and the overall cost is low.
[0005] The technical solution adopted by the utility model is: a noise reduction structure of a high-pressure cleaning machine, which includes a working component, a first air deflector for covering the working component and a cleaning machine shell arranged outside the first air deflector, a first air inlet and a first air outlet are respectively arranged on both sides of the first air deflector, and it also includes a second air deflector covering the first air deflector, a second air inlet and a second air outlet are respectively arranged on both sides of the second air deflector, and an air channel for air flow is arranged between the first air deflector and the second air deflector, the air channel includes a first air channel and a second air channel, the first air inlet and the second air inlet are located on different sides, and the first air inlet is connected to the second air inlet through the first air channel, the first air outlet and the second air outlet are located on different sides, and the first air outlet is connected to the second air outlet through the second air channel.
[0006] Preferably, the first air channel and the second air channel are separated by a partition.
[0007] Preferably, an air baffle for increasing air resistance is provided on the inner wall of the air passage.
[0008] Preferably, an air baffle for increasing air resistance is also provided on the inner wall of the first air deflector.
[0009] Preferably, the air baffle is an annular protrusion, an annular protrusion is provided on both the inner wall and the outer wall of the first air guide cover, and an annular protrusion is provided on the inner wall of the second air guide cover.
[0010] Preferably, the annular protrusion includes a first annular protrusion and a second annular protrusion, the protrusion length of the first annular protrusion is greater than the protrusion length of the second annular protrusion, and the first elongated annular protrusion is arranged in the air channel.
[0011] Compared with the prior art, the utility model adopting the above structure has the following advantages: a second air guide cover is provided, and an air channel is provided between the second air guide cover and the first air guide cover, and the inlet and outlet of the two air guide covers are not on one side, so that the air needs to pass through the air channel after flowing to the outside, which can increase the flow distance of the air, and the noise is transmitted with the air, so this can reduce part of the noise, and because the sound insulation cotton is eliminated, the inside of the cleaning machine is not easy to mold and stink.
[0012] The two air channels are separated by a partition so that the air will not flow out directly, but will pass through the two air channels before flowing out. In this way, the noise will be weakened through the two air channels, achieving better noise reduction function.
[0013] Annular protrusions are arranged on the inner and outer walls of the first air guide cover and the inner wall of the second air guide cover, so that the noise can be better reduced.
[0014] The annular protrusions are set to different lengths, so that the air can collide better during flow, thereby better reducing noise. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.
[0021] Embodiment 1:
[0022] A high-pressure cleaning machine noise reduction structure includes a cleaning machine housing 3, a first air guide cover 2, a second air guide cover 6 and a working component 1, wherein:
[0023] The working component 1 mainly includes a motor and a pump body, and the motor drives the pump body to work to realize pressurized injection of water. This is a conventional component of a high-pressure cleaning machine in the prior art, so it is not described in detail here;
[0024] The cleaning machine housing 3 has air inlets and air outlets on both sides thereof for air to flow in and out;
[0025] A first air guide cover 2 is arranged outside the working component 1 and is used to guide the air. A first air inlet 4 and a first air outlet 5 are arranged on both sides of the first air guide cover 2. When the air is working, the air will flow through the first air inlet 4 and then flow out from the first air outlet 5;
[0026] The second air deflector 6 is arranged outside the first air deflector 2, and an air channel is arranged between the second air deflector 2, and the air channel is divided into two, namely the first air channel 9 and the second air channel 10, which are separated by a partition 11, and the second air inlet 7 and the second air outlet 8 are also arranged on both sides of the second air deflector 6, the second air inlet 7 of the second air deflector 6 is located on both sides of the first air inlet 4 of the first air deflector 2, the second air outlet 8 of the second air deflector 6 is also located on both sides of the first air outlet 5 of the first air deflector 2, and the first air inlet 4 is connected to the air deflector 2 by the first air deflector 2. The air channel 9 is connected with the second air inlet 7, and the first air outlet 5 is connected with the second air outlet 8 through the second air channel 10, so that the air will flow in from the second air inlet 7, and then flow into the first air guide cover 2 through the first air channel 9 and the first air inlet 4 to dissipate heat for the working component 1 and bring out noise, and then the air will flow out of the air guide cover through the first air outlet 5, the second air channel 10 and the second air outlet 8, and finally flow out from the air outlet of the high-pressure cleaner. In this way, the air flow distance becomes longer, so that the noise is partially lost during the flow process, thereby making the overall noise smaller.
[0027] Embodiment 2:
[0028] The difference from the first embodiment is that in the second embodiment, air baffles are provided on the inner wall of the first air guide cover 2 and the inner wall of the air channel, so that the air will collide with the air baffle when flowing, making the air flow distance longer, thereby consuming more noise during the flow process.
[0029] Embodiment three:
[0030] The difference from the second embodiment is that the air baffles in the third embodiment are divided into short baffles 13 and long baffles 12. Since a workroom needs to be installed inside the first air guide cover 2, the air baffles on its inner wall are all short baffles 13. Since the air passage has large spaces in some places and small spaces in others, the air baffles on the inner walls in the small spaces are also short baffles 13, while the long baffles 12 and short baffles 13 are provided on the inner walls in the large spaces, so that the overall noise reduction effect is better.
[0031] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
[0032] For those skilled in the art, various changes and modifications will undoubtedly be obvious after reading the above description. Therefore, the attached claims should be regarded as covering all changes and modifications to the true intent and scope of the utility model. Any and all equivalent ranges and contents within the scope of the claims should be considered to still be within the intent and scope of the utility model.
