Detailed Description
The technical solution in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
It is to be understood that the described embodiments are merely some embodiments and not all embodiments of the present application, and that the following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application and its applications.
The first embodiment is as follows:
as shown in fig. 1-3, the present embodiment provides a noise reduction element for a water purifier, the noise reduction element includes a housing 100 having a cavity, the cavity sequentially includes an inlet chamber 210, a silencing chamber 220 and an outlet chamber 230, and the housing corresponding to the inlet chamber 210, the silencing chamber 220 and the outlet chamber 230 is respectively provided with an inlet section 110, a silencing section 120 and an outlet section 130. Specifically, the sound attenuation section 120 includes an inner shell 121 and an outer shell 122, the sound attenuation cavity 220 includes a hollow cavity 221 and a water passing cavity 222, the inner shell has the water passing cavity 222, the hollow cavity 221 is formed between the inner shell 121 and the outer shell 122, and the hollow cavity 221 is annularly arranged on the periphery of the water passing cavity 222.
Through the periphery in crossing the water cavity sets up well cavity, make well cavity formation puigging and will cross the water cavity cladding wherein, the vibration noise of pulsation rivers impact water cavity inner wall forms to make a round trip to reflect or diffract and offset in well cavity to reduce the outside transmission of vibration noise.
In an alternative implementation manner of this embodiment, as shown in fig. 1 and 2, a diversion plate 123 with a through hole 124 is further disposed in the water passing cavity 222.
The circular through holes on the flow distribution plate form small-hole acoustical panel, water flow is further divided into a plurality of stable flows after passing through the circular small holes on the middle-cavity flow distribution plate, the water flow gradually tends to be stable in the process of passing through the spiral ribs and the small-hole acoustical panel, and phenomena such as reflection, interference and the like are generated due to acoustic impedance change caused by the change of the cross section in the pipeline, so that water flow fluctuation and noise are obviously reduced.
In a preferred implementation manner of this embodiment, as shown in fig. 3, an arc-shaped splitter plate 123 with a through hole is arranged in the water passing cavity, and the arc-shaped splitter plate protrudes towards the water inlet cavity side. Preferably, the arc-shaped splitter plate is 2, and the two splitter plates are arranged oppositely.
Through crossing the protruding arc flow distribution plate of water intracavity side in the water cavity, can increase the area of inlet opening to form more steady stream, further reduce the pulsation of rivers.
Furthermore, the sectional area of the water passing cavity is larger than that of the water inlet cavity. Specifically, in this embodiment, the diameter of the water passing cavity is larger than that of the water inlet cavity.
The sectional area through crossing the water cavity sets up to be greater than the sectional area of intake antrum for the velocity of flow reduces after the pulsating rivers get into the water cavity, thereby further reduces the impact vibration noise of pulsating flow and inner shell, plays the effect of stabilizing rivers.
Example two:
as shown in fig. 4 and 5, the present embodiment is different from the first embodiment in that: the noise reduction element further includes an elastic body, the elastic body is disposed in the sound attenuation chamber to form a hollow cavity 221 between the outer periphery of the elastic body and the inner wall of the housing, that is, the inner housing 121 is made of an elastic material. Preferably, the inner casing 121 is made of silicone material.
Through setting up the inner shell into the elastomer for drive the elastomer after the pulsating water flow that has pressure gets into the cushion chamber, the elastomer takes place to warp and forms the one-level buffering, offsets the vibration that produces when pulsating water flow strikes the elastomer, further noise reduction.
Further, a support rib 122a for supporting the elastic body is disposed on the inner wall of the housing outside the hollow cavity 221. Specifically, the housing 122 is provided with a support rib 122a protruding inward.
Therefore, the elastic body is uniformly stressed in the silencing cavity and is kept stable when being impacted by pulsating water flow.
Further, the hollow cavity 221 is hermetically disposed.
Through the sealed setting with well cavity for when the pulsating water flow assaulted the elastomer, thereby the elastomer warp the interior air of extrusion cavity in back and form the second grade buffering. If the hollow cavity is communicated with the outside, secondary buffering is difficult to realize.
Example three:
as shown in fig. 6 and 7, the present embodiment is different from the first and second embodiments in that: the inner wall of the inlet chamber 210 and/or the outlet chamber 230 is provided with a spiral rib 211.
The high-pressure fluctuation rivers that flow out in the booster pump pass through the intake antrum, and under the water conservancy diversion effect of spiral water conservancy diversion muscle, the rivers that press close to the chamber wall at first flow along the screw direction, and then drive and keep away from the wall and be close to the rivers of center axis position promptly and form stable flow along the screw direction together. When the water flow reaches the junction of the water inlet cavity and the buffer cavity, the water flow still flows spirally under the inertia effect, but the flow rate of the booster pump is constant due to the fact that the cross section area of the cavity is increased, and the flow rate of the water flow is further reduced.
By arranging the spiral ribs on the inner wall of the water inlet cavity and/or the water outlet cavity, the pulsating high-pressure water flow forms stable water flow under the rotating flow guiding action of the spiral ribs, and meanwhile, the impact force of the high-pressure fluctuating water flow on the wall surface of the inner channel of the upper cavity and the lower cavity is reduced, so that the vibration and the noise are reduced.
Furthermore, the ratio of the inner diameter D1 of the water inlet cavity 210 and/or the water outlet cavity 230 to the height H1 of the spiral rib 211 ranges from 5 to 10.
If the ratio is greater than 10, the spiral flow guiding effect of the spiral ribs is obviously reduced, stable water flow cannot be formed, and the effect of the spiral ribs is not beneficial to the condition that the spiral ribs are not arranged; if the ratio is less than 5, the height of the spiral rib is too high, so that the pulsating high-pressure water flow is blocked by the spiral rib to receive a large impact force, and the vibration during the impact is increased.
Further, the spiral angle range of the spiral rib 211 is 30-45 degrees.
Under the condition that the height of the flow guiding ribs is fixed, the larger the spiral angle of the spiral ribs is, the better the flow dividing effect is, but the larger the resistance applied when water flows through the spiral ribs is also caused. Therefore, the spiral angle range of the spiral ribs is 30-45 degrees, a good flow distribution effect can be guaranteed, and smooth passing of water flow can be guaranteed.
Furthermore, the inner walls of the water inlet cavity and the water outlet cavity are simultaneously provided with spiral ribs, and the spiral directions are the same.
The spiral ribs with the same rotating direction are arranged on the inner walls of the water inlet cavity and the water outlet cavity at the same time, so that water flow can be further stabilized, and the pulsating impact of the water flow on the pipe wall is reduced.
Preferably, the length of the spiral rib is not more than one pitch.
If the length of the spiral rib is larger than one screw pitch, the pulsating high-pressure water flow is blocked by the spiral rib for a long distance to be subjected to a larger impact force, and the vibration during the impact is increased.
Example four:
as shown in fig. 8, in this embodiment, there is provided a water purifier having the noise reduction element according to any one of the first to third embodiments, the water purifier includes a housing 400, a booster pump 200 and a reverse osmosis filter 300 are disposed in the housing, and the booster pump 200 is disposed upstream of the reverse osmosis filter 300.
Further, the noise reduction element is disposed between the booster pump 200 and the reverse osmosis filter 300.
Because the high-pressure water flow pulsation after being pressurized by the booster pump is most obvious, especially on a pipeline between the booster pump and the reverse osmosis filter element, the vibration noise in the section of the pipeline can be effectively reduced by arranging the noise reduction element between the booster pump and the reverse osmosis filter element.
Based on the principle of reverse osmosis water purification, tap water can be pushed to permeate through the selective membrane by the pressure higher than osmotic pressure, the flow speed of the water flow is obviously reduced in the permeation process, and the pulsation influence of the pulsating water flow is obviously weakened. Therefore, in order to further enhance the noise reduction effect, the length of the pipeline between the noise reduction element and the booster pump needs to be shortened so as to reduce the pulsation of the high-pressure water flow from the booster pump as soon as possible. Preferably, the length of a pipeline between the booster pump and the reverse osmosis filter element is not more than 30 cm.
In order to further improve the noise reduction effect, the length of the pipeline between the noise reduction element and the booster pump needs to be shortened so as to reduce the pulsation of the high-pressure water flow from the booster pump as soon as possible. Optionally, the distance between the water inlet of the noise reduction element and the water outlet of the booster pump is not more than 15 cm. Preferably, the water inlet end of the noise reduction element is directly butted with the water outlet of the booster pump through an adapter.
Further, the reverse osmosis filter element 300 is further provided with a waste water port (not shown in the figure), the waste water port is connected with a waste water valve (not shown in the figure), and the downstream of the waste water valve is provided with the noise reduction element.
Due to the throttling function of the waste water valve, the waste water at the downstream of the waste water valve flows fast and collides with air to form noise. By disposing it downstream of the waste water valve, noise generated when waste water is discharged can be reduced.
