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 cleaning machine 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 working components inside the high-pressure cleaning machine will vibrate to a certain extent when they are running, and will also generate certain vibration noise. This vibration noise cannot be effectively isolated by the sound insulation cotton layer. 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 adopting the noise reduction structure can better reduce vibration noise.

[0005] The technical solution adopted by the utility model is: a noise reduction structure of a high-pressure cleaning machine, including a working component, a guide cover covering the working component and a cleaning machine shell covering the guide cover, a first shock-absorbing ring is arranged between the working component and the guide cover, and a second shock-absorbing ring is arranged between the guide cover and the cleaning machine shell.

[0006] Preferably, the working component includes a motor part and a pump body part, and the pump body part is provided with a water inlet and a water outlet. There are three first shock-absorbing rings, and one of them is mounted on the outside of the motor part, and the other two are respectively mounted on the water inlet and the water outlet of the pump body.

[0007] Preferably, there are two second shock absorbing rings, and the two second shock absorbing rings are arranged on both sides of the outside of the air deflector.

[0008] Preferably, each second shock-absorbing ring is composed of two parts.

[0009] Preferably, a first installation groove for embedding and installing a first shock-absorbing ring is provided on the inner wall of the air guide cover, and a second installation groove for embedding and installing a second shock-absorbing ring is provided on the inner wall of the cleaning machine housing.

[0010] Preferably, a support bar is provided at the bottom of the second mounting groove for supporting the second shock absorbing ring and matching the shape of the second shock absorbing ring.

[0011] Compared with the prior art, the utility model adopts the above structure and has the following advantages: shock-absorbing rings are arranged between the working component and the air deflector, and between the air deflector and the cleaning machine housing, so that the working component is not in direct contact with the air deflector, so that the noise generated by the working component vibrating during operation will be much less, and the air deflector is not in direct contact with the cleaning machine housing, so that the noise generated by the vibration transmitted from the working component to the air deflector will be much less, thereby achieving the effect of greatly reducing noise.

[0012] The number of the first shock-absorbing rings is set to three, so that the working component can be well separated from the air deflector.

[0013] The deflector covers are sleeved on both sides of the outside of the deflector cover, so that the two second shock-absorbing circles are subjected to more uniform force.

[0014] Divide the second shock-absorbing ring into two parts to facilitate the installation and fixation of the second shock-absorbing ring.

[0015] Installation grooves are arranged on the inner wall of the air guide cover and the inner wall of the cleaning machine housing, so that it is convenient to install and fix the damping ring, so that when the working component is working, the damping ring will not move due to vibration.

[0016] A support strip is arranged at the bottom of the installation groove, so that the bottom of the installation groove does not need to be completely matched with the shock-absorbing ring, and the support strip only needs to be made into a shape matching the shock-absorbing ring.

[0025] The working assembly includes a motor part 5 and a pump body part 6. The motor part 5 drives the pump body part 6 to pressurize the water. This is a relatively conventional product in the prior art, so it is not described in detail again.

[0026] The deflector 1 has three first damping rings 3 arranged between it and the working component, one of which is sleeved on the outside of the motor part 5, and the first damping ring 3 is made of cotton material, and the other two first damping rings 3 are respectively sleeved on the water inlet 7 and the water outlet 8 of the pump body part 6, and the two first damping rings 3 are made of rubber material, and first mounting grooves 9 for the three first damping rings 3 to be embedded are respectively arranged at the corresponding positions of the deflector 1, so that when the working component is installed, the three first damping rings 3 can be sleeved on the corresponding positions first, and then the working component can be installed in the deflector 1, and the three first damping rings 3 are embedded in the three first mounting grooves 9;

[0027] The cleaning machine housing 2 has two second shock-absorbing rings 4 arranged between it and the air deflector 1. The two second shock-absorbing rings 4 are arranged on both sides of the outside of the air deflector 1 and are both made of cotton material. Moreover, the two second shock-absorbing rings 4 are both composed of two parts, which is convenient for installation.
