[0030] The technical solution of the present invention will be described in a clear and initial state in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The present invention provides a muffler and a water purifier. A plurality of embodiments are given below to describe the muffler and the water purifier provided by the present invention in detail.

[0032] Example 1

[0033] The muffler provided in this embodiment is as follows: Figures 1 to 3 As shown, it includes a shell 1 and an elastic ball 6; the shell 1 is provided with a water inlet and a water outlet, and the shell 1 has a water outlet cavity 12 and a water inlet cavity 11 inside, the water inlet cavity 11 is connected with the water inlet, and the water outlet cavity 12 is connected with the water outlet; the water inlet cavity 11 and the water outlet cavity 12 are both provided with an elastic ball 6, and the elastic ball 6 is provided with a plurality of through holes 61.

[0034] Part of the water flow in the water inlet cavity 11 and the water outlet cavity 12 can flow into the through hole 61 of the elastic ball 6. At the same time, the water flow pressure can drive the elastic ball 6 to rotate. Part of the water flow energy is absorbed by the elastic ball 6, which can reduce the water flow velocity and thus improve the sound insulation effect.

[0035] The through hole 61 may be in any suitable shape such as a circle, a triangle or a rectangle.

[0036] Furthermore, the muffler also includes a bracket 5 and an intermediate pipe 4; a water outlet hole 51 is provided on the bracket 5, the bracket 5 is fixed in the shell 1, and the bracket 5 can divide the shell 1 into multiple cavities; the cavities located at the two ends of the multiple cavities are respectively a water inlet cavity 11 and a water outlet cavity 12; the intermediate pipe 4 passes through the bracket 5, and one end of the intermediate pipe 4 is connected to the water inlet cavity 11, and the other end of the intermediate pipe 4 is connected to the water outlet cavity 12.

[0037] The middle pipe 4 and the bracket 5 can realize the diversion flow of water. The water flow is divided into two circuits and flows in the muffler. One part of the water flows from the water inlet cavity 11 through the middle pipe 4 to the water outlet cavity 12, and the other part of the water flows through the water outlet hole 51 on the bracket 5 to the water outlet cavity 12, thereby realizing the diversion flow of the water flow, reducing the water flow pressure, and slowing down the water flow speed.

[0038] The number of the bracket 5 can be one or more.

[0039] Preferably, there are a plurality of brackets 5 , and the plurality of brackets 5 are arranged in the housing 1 at intervals along the axial direction of the housing 1 .

[0040] The number of the brackets 5 can be any suitable number, such as two, three or four. The shell 1 is divided into at least three cavities by multiple brackets 5, wherein the cavities at the two ends of the multiple cavities are the water inlet cavity 11 and the water outlet cavity 12, and the cavity located in the middle of the multiple cavities is the intermediate cavity 13.

[0041] After the water flows into the water inlet cavity 11, it is divided into two circuits and flows in the muffler. One part of the water flows from the water inlet cavity 11 through the intermediate pipe 4 to the water outlet cavity 12, and the other part of the water flows through the water outlet hole 51 on the bracket 5, flows through the intermediate cavity 13 in sequence, and finally flows to the water outlet cavity 12, thereby realizing the diversion flow of the water flow, further reducing the water flow pressure, and slowing down the water flow speed.

[0042] In addition, part of the water flow in the water outlet cavity 12 flows from the water inlet cavity 11 through the middle tube 4, and the other part flows through the water outlet hole 51 on the bracket 5. The two water flows merge to form a stable water flow after the pressure is reduced in the water outlet cavity 12, and the water outlet cavity 12 further lengthens the water flow path.

[0043] Furthermore, there are two brackets 5, and the cavity between the two brackets 5 is the middle cavity 13; along the axial direction of the shell 1, the lengths of the water inlet cavity 11 and the water outlet cavity 12 are 30 mm, and the length of the middle cavity 13 is 25 mm.

[0044] The two brackets 5 divide the housing 1 into three expansion chambers, which are the water inlet chamber 11, the middle chamber 13 and the water outlet chamber 12 in the direction of water flow. The water flows into the water inlet chamber 11 from the water inlet, and then is divided into two paths, one path enters the water outlet chamber 12 through the middle pipe 4, and the other path enters the middle chamber 13 through the water outlet hole 51 on the bracket 5, and then enters the water outlet chamber 12 through the water outlet hole 51 on the bracket 5.

[0045] The water in the first expansion chamber flows to the third expansion chamber through the middle tube 4, and part of the water flows to the second expansion chamber through the small holes on the bracket 5, thereby realizing the diversion flow between the second expansion chamber and the middle tube 4 and reducing the water flow pressure.

[0046] There may be one or more intermediate tubes 4 .

[0047] Furthermore, there are a plurality of water outlet holes 51 , and the plurality of water outlet holes 51 are evenly spaced apart along the circumference of the bracket 5 .

[0048] The shape of the water outlet 51 can be any suitable shape such as a circle, a triangle, a rectangle or a pentagon.

[0049] In this embodiment, the bracket 5 is provided with 32 circular water outlet holes 51 with a diameter of 2 mm.

[0050] Furthermore, the muffler also includes a water inlet pipe 2 and a water outlet pipe 3; along the axial direction of the shell 1, the shell 1 includes a first end face and a second end face that are relatively arranged, the first end face is arranged adjacent to the water inlet cavity 11, and the second end face is arranged adjacent to the water outlet cavity 12; one end of the water inlet pipe 2 passes through the second end face and the bracket 5 in sequence, and one end of the water inlet pipe 2 is connected to the water inlet cavity 11, and the other end of the water inlet pipe 2 is located outside the shell 1; one end of the water outlet pipe 3 passes through the first end face and the bracket 5 in sequence, and one end of the water outlet pipe 3 is connected to the water outlet cavity 12, and the other end of the water outlet pipe 3 is located outside the shell 1.

[0051] The pressurized water flow from the booster pump enters the muffler. The water flow entering the muffler is first decelerated under the action of gravity. In addition, due to the expansion of the expansion chamber of the muffler, the water flow speed will be further slowed down. The water flows in through the water inlet pipe 2, fills the first water inlet chamber 11, and then splits into two paths. One path flows directly into the water outlet chamber 12 through the intermediate pipe 4, and the other path flows into the intermediate chamber 13 through the water outlet hole 51 on the bracket 5 and finally flows into the water outlet chamber 12. After the two water flows merge in the water outlet chamber 12, they flow out of the muffler through the water outlet pipe 3 to form a stable water flow. The water flow is divided into two flows, so that the water flow flows alternately in multiple expansion chambers, which significantly lengthens the water path, greatly slows down the water flow speed, and thus reduces the vibration and noise generated by the water flow.

[0052] Furthermore, along the axial direction of the shell 1, the longitudinal cross section of the shell 1 is elliptical. Compared with the muffler with a circular longitudinal cross section in the prior art, the muffler provided in this embodiment can achieve a larger expansion ratio, and the water flow speed decreases faster after flowing into the muffler provided in this embodiment.

[0053] In this embodiment, the diameter of the elastic ball 6 is 9 mm, the diameter of the through hole 61 is 1 mm, the diameter of the water inlet pipe 2 is 7 mm, the diameter of the water outlet pipe 3 is 7 mm, and the diameter of the intermediate pipe 4 is 8.5 mm.

[0054] In the silencer provided in this embodiment, part of the water flow in the water inlet cavity 11 and the water outlet cavity 12 can flow into the through hole 61 of the elastic ball 6. At the same time, the water flow pressure can drive the elastic ball 6 to rotate. Part of the water flow energy is absorbed by the elastic ball 6, which can reduce the water flow velocity, thereby improving the silencer effect.

[0055] Example 2

[0056] The water purifier provided in this embodiment includes the muffler provided in embodiment 1. Part of the water flow in the water inlet cavity 11 and the water outlet cavity 12 can flow into the through hole 61 of the elastic ball 6, and at the same time, the water flow pressure can drive the elastic ball 6 to rotate, and part of the water flow energy is absorbed by the elastic ball 6, which can reduce the water flow velocity, thereby improving the muffler effect.

[0057] The water purifier provided in this embodiment can reduce the operating noise of the whole machine by more than 5dB, greatly weaken the pulsation of the water flow, and significantly improve the auditory experience of the water purifier during operation.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
