Description

Technical Field

[0001] The utility model relates to water supply equipment, in particular to a water inlet damping and silencing device for a domestic water tank. Background Art

[0002] Domestic water tanks are containers for storing and supplying domestic water. They are widely used in residences, commercial buildings, hospitals, schools and other places. The design and use of domestic water tanks need to consider many factors, including capacity, materials, hygiene, installation location, maintenance and safety. A main water inlet pipe is connected to the domestic water tank. When the domestic water in the domestic water tank is insufficient, the domestic water in the domestic water tank is supplemented through the water inlet pipe. Since the water inlet pipe is arranged at a high place of the domestic water tank and there is a large height difference, if the pressure of the water inlet pipe is too large, it will cause greater vibration and noise, thereby causing a certain noise impact on the living environment around the domestic water tank. Based on the above problems, the present invention was conceived. Utility Model Content

[0003] The utility model aims to provide a water inlet shock-absorbing and silencing device for a domestic water tank, which can reduce the noise and vibration when the domestic water tank is filled with water, and avoid the influence on the surrounding living environment.

[0004] The above-mentioned technical purpose of the utility model is achieved through the following technical scheme: a domestic water tank inlet shock-absorbing and silencing device, comprising a domestic water tank with a water storage chamber and a water inlet pipe connected to the water storage chamber, an elimination zone is formed in the water storage chamber corresponding to the area in front of the water outlet of the water inlet pipe, a silencer buffer block is movably arranged in the elimination zone, a plurality of silencer micropores are distributed on the silencer buffer block, the silencer buffer block has a counteracting buffering potential energy moving toward the side of the water inlet pipe outlet, a drainage plate is provided below the elimination zone, and a drainage structure is formed between the drainage plate and the domestic water tank.

[0005] By adopting the above technical solution, water flows out of the water inlet pipe and acts on the corresponding silencer buffer block. The silencer buffer block offsets the impact of the water outflow through the offset buffer potential energy and cooperates with a number of silencer micropores formed on the silencer buffer block to disperse the concentrated impact of the disturbing water flow, slow down the water flow rate and absorb the energy generated by the water flow impact, thereby achieving the purpose of buffering, shock absorption and silence. After the silencer buffer block acts, the water flows down and flows toward the drainage plate below, and guides the water flow to fall under the action of the drainage structure, reducing the noise generated by the water flow during the falling process, achieving a better silencer purpose, and avoiding its impact on the surrounding living environment.

[0006] It is further configured as follows: it includes a guide groove formed on the wall of the water storage chamber, the silencer buffer block is slidably set on the guide groove, one end of the guide groove extends toward the water inlet pipe outlet and corresponds to the direction of the water inlet pipe outlet, and the other end is bent upward and gradually extended away from the water inlet pipe outlet.

[0007] By adopting the above technical solution, the silencer buffer block moves along the guide groove toward the water outlet of the water inlet pipe under the action of gravity. The gravity potential energy generated by the silencer buffer block is used to offset the impact of the jetting water flow and cooperate with a number of silencer microholes to achieve the purpose of vibration reduction and silencing.

[0008] It is further configured as follows: a falling buffer block is provided between the elimination zone and the guide plate, a plurality of buffer micropores are distributed on the falling buffer block, the cross-sectional shape of the falling buffer block facing the silencer buffer block is adapted to the shape of the guide groove, and the silencer buffer block does not contact the falling buffer block when moving along the guide groove.

[0009] By adopting the above technical solution, the falling buffer block cooperates with a number of buffer micropores formed therein to reduce the impact force of the water flow when it falls, thereby reducing noise. And by setting the falling buffer block into the above shape, when the impact force of the water flow is too large, the water flow leaving the silencer buffer block after the silencer buffer block is excessively deflected can act on the falling buffer block for buffering and silencing, thereby achieving better vibration reduction and silencing purposes.

[0010] It is further configured as follows: the drainage structure includes a drainage protrusion formed on the drainage plate protruding toward the elimination area, a flow gap formed between the drainage plate and the side wall of the water storage chamber, and a guide slope formed on one side wall of the water storage chamber corresponding to the flow gap and gradually inclined inward.

[0011] By adopting the above technical solution, the drainage protrusion guides the water flow to move toward the flow gap, and the water falling from the flow gap drips onto the guiding slope for drainage, thereby avoiding the noise generated by the water flow dripping directly into the water body.

[0012] It is further configured that: a suction pad is provided on one side of the guide plate facing the elimination area.

[0013] By adopting the above technical solution, the suction pad absorbs the energy of dripping water, thereby achieving the purpose of silencing.

[0014] It is further configured as follows: a rubber shock-absorbing block is connected between the guide plate and the water storage cavity wall.

[0015] By adopting the above technical solution, the rubber shock-absorbing block absorbs the energy of the water flow acting on the drainage plate, so as to achieve the purpose of shock absorption.

[0016] In summary, the utility model has the following beneficial effects: the utility model can reduce the noise and vibration when the domestic water tank is filled with water, thereby avoiding the impact on the surrounding living environment. BRIEF DESCRIPTION OF THE DRAWINGS
