Description

Gasket that can change the inlet pore size according to the water pressure

The invention relates to a gasket structure, in particular to a gasket applied to a filter and a shower head for changing the water inlet aperture according to the water pressure.

According to the California Energy Commission, the latest water-saving regulations for the bathroom supplies (new California water restrictions), the faucet equipment sold since then, need to reduce water consumption, is expected to save 10.3 billion gallons of water in the first year, California Energy The Commission's (California Energy Commission) requires that the sale of faucets must reduce water use. For example: (1), the household bathroom faucet can not exceed 1.2 gallons per minute, the previous rule is 2.2 gallons. (2) The water consumption of the public bathroom faucet shall not exceed 0.5 gallons per minute. (3) The kitchen faucet must have a flow rate of less than 1.8 gallons per minute, but it can be increased in speed. When it is connected to the pot, it can be increased to 2.2 gallons per minute. A water-saving device (Aerator), as shown in FIG. 11, has a faucet 40 locked with a wave device 41, and the wave damper 50 is sequentially mounted in a casing 51. The wave member 52, a water dividing plate 53 and a throttle piece 54 are provided with a leakage preventing washer 55 between the waver 40 and the water outlet pipe 41, so that the water flow can sequentially flow through the orifice 541 of the throttle piece 54, The water dividing plate 53 and the wave absorbing member 52, and the reduced flow diameter of the orifice 541 restricts the water flow rate, thereby achieving the water-saving and water-flow effect of the faucet 40. However, it is not difficult to find out that the above-mentioned conventional structure is still somewhat present. In the deficiencies, the throttle piece 54 is a hard plate body, so that the aperture of the orifice 541 is fixed, and the blockage of the orifice 541 is prevented from being too small, and the conventional orifice 541 is designed to be larger than California. The amount of water discharged by the new water limit regulation, so when the water flow pressure is low, the orifice 541 is formed. The water column flow rate is insufficient, so that the suction force that relies on the flow rate to attract the air mixture is reduced (the white effort law), so that the water flow cannot be effectively cleaned, so that the extension of the cleaning time will be more wasteful of water, and when the water flow increases, due to the throttle piece 54 The orifice diameter of the orifice 541 is constant, and the water discharge amount cannot be adjusted according to the water pressure. Therefore, the increased water pressure will increase the amount of water flowing, so that the water saving effect is lowered, and the new regulations of the California water restriction cannot be met, In accordance with the regulations, replacing the pipeline of the entire faucet does not meet the economic benefits, and will greatly reduce the user's willingness to change, making it difficult to implement the new water restriction regulations in California. As in the US patent case US20130032231, there is also the inability to adjust the water output. The problem is that it does not have a good water saving effect.

On the other hand, the conventional showerhead structure, as shown in Fig. 12, the lotus The head 60 is mainly connected to a water outlet 62 by a pipe body 61, and a gasket 63 is formed between the pipe body 61 and the water outlet head 62 to form a leakage preventing effect, and the water outlet head 62 is provided with a plurality of water sprinkling holes. 621 is used for generating a water-like water discharge effect, and the conventional shower head 60 is designed to have a water-saving effect, and a throttle piece 64 is added to the joint between the pipe body 61 and the water discharge head 62, due to the hard throttle piece. The pore diameter of 64 is constant, and the water output cannot be adjusted according to the water pressure. Therefore, the increased water pressure will increase the amount of water flowing, which will reduce the water saving effect. To improve the water saving effect, the entire water head 62 must be replaced. It does not appear to be economically viable, and it will greatly reduce the user's willingness to change, making it difficult to implement the new water restriction regulations in California. Therefore, if only the gasket 63 can be replaced, the shower head 60 can save water and effectively reduce the replacement cost.
