Description

Technical Field

[0001] The present disclosure relates to the technical field of water flow silencing, and in particular to a silencing net, a moving plate and a mixing valve. Background Art

[0002] The hot and cold water mixing valve comprises a rotor cover, a rotor, a static plate and a bottom shell. The rotor is mounted on the upper part of the static plate. The static plate has two water inlet holes and one water outlet hole. The rotor has a rotor diverter hole. The upper part of the rotor diverter hole is sealed by the rotor cover. The rotor diverter hole is connected to the two water inlet holes and one water outlet hole of the static plate, that is, the water flow coming in from the two or one water inlet holes of the static plate first enters the rotor diverter hole, and then enters the water outlet hole of the static plate through the rotor diverter hole and is then discharged; when the rotor diverter hole is connected to a single water inlet hole of the static plate and the other is closed, it is a single-channel water inlet at this time. When the rotor diverter hole is connected to both water inlet holes of the static plate, it is a double-channel water inlet at this time, that is, cold water and hot water both enter the rotor diverter hole, and are mixed in the rotor diverter hole, and then are discharged through the water outlet hole of the static plate for use; when the existing rotor and static plate are used in coordination, when the water flow rushes from the water inlet hole of the static plate into the rotor diverter hole, it will cause a large noise.

[0003] Therefore, the present application proposes a silencer net, a moving plate and a mixing valve. Summary of the invention

[0004] In order to solve at least one of the above technical problems, the present disclosure provides a silencer net, a moving plate and a mixing valve.

The first wall is opposite to the second wall, and the third wall is opposite to the fourth wall. The upper and lower ends of the sound-absorbing net are open. The first wall, the second wall, the third wall, and the fourth wall are all in a net shape, and the bottom of the first wall has a hook.

[0007] Preferably, a plurality of the hooks are distributed at intervals along the width direction of the first wall.

[0008] Preferably, at least a portion of the hook portion is bent upward.

[0011] Preferably, the sound-absorbing net is made of metal or plastic.

[0012] Preferably, the sound-absorbing net is a rigid structure.

[0013] A moving plate is provided with a moving plate diversion hole, in which the aforementioned silencing net is installed, and the silencing net is adapted to the moving plate diversion hole.

[0014] A mixing valve comprises an outer shell, in which a moving plate cover, the moving plate and a static plate are installed from top to bottom, a bottom shell is installed at the bottom of the outer shell, the static plate has a water inlet hole and a water outlet hole, and the hook at the bottom of the first wall is vertically aligned with the water inlet hole.

[0015] Preferably, the movable plate cover has a plurality of vertical teeth, and the bottoms of the vertical teeth are vertically inserted into the hook.

[0016] To sum up, the silencer net of the present application can break up the direction of water flow, and when water flows in, it can form a backflow through the hook, so that the sound of water flow is reduced from 30 decibels to below 20 decibels, reaching the international first-level standard. At the same time, it will not affect the water flow, and effectively play a noise reduction role. BRIEF DESCRIPTION OF THE DRAWINGS

The present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] like Figures 1 to 5 As shown, a sound-absorbing net, the sound-absorbing net 1 is made of metal and plastic, the sound-absorbing net 1 is a rigid structure so as to form a self-support, the sound-absorbing net 1 is surrounded by a first wall 1-1, a second wall 1-2, a third wall 1-3, and a fourth wall 1-4, the first wall 1-1 is opposite to the second wall 1-2, the third wall 1-3 is opposite to the fourth wall 1-4, the upper end and the lower end of the sound-absorbing net 1 are open, the first wall 1-1, the second wall 1-2, the third wall 1-3, and the fourth wall 1-4 are all in a mesh shape, and the bottom of the first wall 1-1 has a hook 1-5; the sound-absorbing net 1 is mainly used for installation Installed in the moving plate 2 of the mixing valve, when the water flows into the diversion hole 2-1 of the moving plate, the hooks 1-5 of the silencer net 1 and the mesh walls play a role in breaking up the direction of the water flow and thus reducing noise. Specifically, a plurality of hooks 1-5 are spaced apart along the width direction of the first wall 1-1, wherein at least a portion of the hooks 1-5 are bent upward, and a plurality of hooks 1-5 act together on the water flow coming from bottom to top. The hooks are arranged to be bent upward to form an inverted bag, which has a better effect of breaking up the direction of the water flow. Arranging a plurality of hooks further improves the breaking up effect and improves the noise reduction effect.

[0032] The upper opening of the silencer net 1 is circular, and the width of the lower opening of the silencer net 1 gradually decreases from the first wall 1-1 to the second wall 1-2. The third wall 1-3 includes a first inclined portion 1-3-1 and a first vertical portion 1-3-2. The fourth wall 1-4 includes a second inclined portion 1-4-1 and a second vertical portion 1-4-2. Such a structural design allows the silencer net 1 to better adapt to the moving plate diversion hole 2-1 of the moving plate 2, which is convenient for installation and disassembly operations.

[0033] like Figures 3 to 5 As shown, a moving plate, the moving plate 2 has a moving plate diversion hole 2-1, the moving plate diversion hole 2-1 is installed with the aforementioned silencer net 1, the silencer net 1 is adapted to the moving plate diversion hole 2-1, the moving plate 2 is mainly used to be installed in the housing 3 of the mixing valve, and is used in conjunction with the moving plate cover 4 and the static plate 5.

[0034] like Figures 5 to 8 As shown, a mixing valve comprises a shell 3, in which a moving plate cover 4, the aforementioned moving plate 2 and a static plate 5 are installed from top to bottom, a bottom shell 6 is installed at the bottom of the shell 3, the static plate 5 has a water inlet hole 5-1 and a water outlet hole 5-2, a hook portion 1-5 at the bottom of the first wall 1-1 is vertically aligned with the water inlet hole 5-1, the moving plate cover 4 has a plurality of vertical teeth 4-1, the bottom of the vertical teeth 4-1 is vertically inserted into the hook portion 1-5, and the vertical teeth 4-1 cooperates with the hook portion 1-5 to further break up the direction of the running water flow and achieve a better noise reduction effect.

[0035] When the water flow coming in from the water inlet hole 5-1 of the static plate 5 enters the diversion hole 2-1 of the moving plate, the direction of movement is broken up by the silencer net 1 installed in the diversion hole 2-1 of the moving plate, the hook 1-5 at the bottom of the silencer net 1, and the vertical tooth 4-1, thereby effectively reducing the noise there. Then, the water flow enters the water outlet hole 5-2 of the static plate 5 through the diversion hole 2-1 of the moving plate and is then discharged. The noise reduction effect is significantly better than that of the existing mixing valve structure.
