Sealed improved structure of liquid flow counting quantitative switch

The present invention relates to a liquid flow counting device, and more particularly to a sealed improved structure of a liquid flow counting and quantitative switch mounted on an outlet pipe connected to a water outlet end of the water purifier.

In order to meet the needs of modern people, the development of science and technology has progressed, but the relative pollution sources have increased relatively, which has adversely affected the environment. In particular, many factories have not directly treated the wastewater according to law and directly discharged the wastewater directly into the stream. These streams contain large amounts of heavy metals and harmful microorganisms. In addition, the domestic waterworks are taken from these streams, so for the sake of safety, the water plant supplies a large amount of disinfectant to the drinking water for the household, which causes the drinking water to have the smell of disinfecting water, which is difficult to drink and use. Numerous water purifiers are born.

In the specification of the "Apparatus for monitoring cumulative flow of fluid through a filter medium" shown in the U.S. Patent No. 5,622,618, the disclosure of which is incorporated herein by reference. The liquid flow counter, and the liquid flow counting and quantitative switch, when it reaches the set flow value, stops supplying water to the water purifier, thereby prompting the user to replace the filter timing, and the liquid flow counting quantitative switch is used The valve body (element 130 in the U.S. specification) is a wafer body, and the center of the wafer body extends a round rod, wherein the wafer body is provided with a tapered portion (element 140 in the US specification), and A blocking block (element 150 in the U.S. specification) is provided at the junction of the wafer body and the round rod, and the conventional valve body is provided in a central fisheye hole of the housing (component 12 in the U.S. specification). Element 162) in the US specification slides, but the gap between the body of the valve body and the center fish eye is too large and is subjected to the elastic force of the elastic member (component 174 in the US specification), often causing the valve body to be skewed. Positively, causing the tapered portion of the valve body to be sealed between the tapered recess above the center fisheye (element 160 in the U.S. specification) and the block, the front end of the spout (element 128 in the U.S. specification) Incomplete, causing the water purifier to reach the set flow rate, the problem of completely failing to shut off the water, and still giving water to the user, and thus the product with the fluid control system will generate unstable signals and directly affect Associate the service life of peripheral products, such as the service life of pressurized pumps, heating and cooling equipment, or other related equipment.

Furthermore, the water flow pressure in the water source pipe is from a pressurized pump provided on the water purifier, and a water flow inductive switch is used to pressurize the water flow, so if the liquid flow rate of the conventional structure is counted in the quantitative switch When the valve body reaches the set flow rate, if the valve body cannot completely close the water outlet, and the water will be discharged briefly and continuously, the pressure pump will still start temporarily and continuously and pressurize the water source pipe. Knowing the structure in this way consumes more power and reduces the life of the pressurized pump and heating and cooling equipment.

Therefore, the main purpose of this creation is to provide a sealed improved structure of a liquid flow counting quantitative switch that saves power and avoids reducing the service life of its associated devices. The secondary purpose of this creation is to provide a sealed improved structure for a liquid flow counting and quantitative switch that is easier and faster to assemble the valve body.

In order to carry out the above-mentioned purposes, the creator created a liquid-flow-counting quantitative switcher with a long-term research and concept of a liquid flow counting and quantitative switch, which is provided with a water inlet and a water outlet in a casing. a nozzle, and a driving tooth, a counting device, a valve body and an elastic body are arranged in the housing, and the driving tooth is connected in series with the counting device, and the counting device is connected to the valve body, and the valve is connected The body is disposed in a central fisheye hole of the lower inner space of the casing and is supported by the elastic body, and is characterized in that: a conical concave is arranged above the center fisheye hole of the casing a groove, wherein the valve system is disposed as a center of a wafer body extending a round rod, wherein the wafer body is provided with a tapered portion, and a synthetic partial elastic sealing element is attached to the tapered portion, and the circle is a plurality of supporting blocks and a blocking block are disposed at the connection between the sheet body and the round rod, and the plurality of supporting blocks are slid in the center fish hole of the housing, so that the valve body is opposite to the The center fish eye hole is not skewed, making the valve body tapered The synthetic partial elastic sealing element on the upper portion is biased to the tapered groove above the central fisheye hole of the housing, and the blocking block of the valve body completely closes the front end of the housing outlet to ensure For products with fluid control systems, a more stable signal will be generated without affecting the service life of the associated peripherals, such as the service life of pressurized pumps, heating and cooling equipment or other related equipment.
