If adopt the mode of leaning forward to close water, its inlet valve, back-moving spring, valve handgrip, buffer table all are located at the front portion, and the center of gravity locating platform is located at the rear portion, and the kettle seat board presents low early and high after gradient when closing water.
As when adopting the hypsokinesis mode to close water, its inlet valve, back-moving spring, valve handgrip, buffer table all are located at the rear portion, and the center of gravity locating platform is located at the front portion, the low gradient in high back before the kettle seat board appears when closing water, the kettle Guan Shui that can recede.
When being applied to water purification machine, its inlet valve must be assemblied on the preceding runner of reverse osmosis membrane water inlet tube mouth, and the water inlet of reverse osmosis membrane pipe is closed when guaranteeing to close water automatically.
During operation kettle seat, first jockey valve water inlet rotates up the outer switching knob of kettle seat; The valve handgrip can prop up kettle seat board below up synchronously in the same way with switching knob, supports empty kettle and keeps balance not weigh down, and delivery port water filling is immediately gone in the kettle; After kettle water inlet, the kettle center of gravity can with water level increase by after gradually to reach, water level rises to height of design behind the water filling certain hour; The center of gravity of kettle begins to change, and the kettle center of gravity is transferred to foremost finally, and moment is unbalance; Kettle and kettle seat board turn forward, and kettle and kettle seat board driven in synchronism valve handgrip are downward, till the water of automatic pass.
Use the kettle water intaking to meet the life normality, the element that the present invention adopts is few, safe and reliable, time saving and energy saving; Cost is low, does not have power consumption, produces soon, and there is urgent demand in market; Especially to forgetful memory loss person, or the handicapped person, the colony that eyes are blind is very helpful in daily life.
The specific embodiment:
As shown in Figure 1; The present invention shifts the kettle seat that closes water automatically for a kind of center of gravity of utilizing; Its structure is to be combined with pipeline by a kettle pedestal 01 and an inlet valve 02 and delivery port 08, the poised state of kettle 03 when the kettle pedestal 01 that around has, encircles the limit keeps the injecting process, and there is a kettle seat board 07 its inside from top to bottom ground floor; Is furnished with a back-moving spring 04 vertical compression base plate 011 in the front groove of kettle seat board 07 below; The second layer is fixed with a center of gravity positioning table 051 on the base plate 011 of kettle pedestal 01, be provided with a buffer table 05 on the base plate 011 in the kettle front wall simultaneously, in kettle pedestal 01 base plate 011 lateral location; Be fixed with an inlet valve 02 and stretch into the kettle seat board 07 time with a valve handgrip 021; Outside kettle seat front wall, have on the corresponding linear position of a valve shaft core switching knob 022 is housed, the water inlet of valve 02 connects inlet pipeline water inlet at kettle pedestal 01 rear, and the connection of delivery port 08 usefulness pipeline is positioned at the 01 top water outlet of kettle pedestal; Kettle 03 places on the interior kettle seat board 07 of kettle seat, be positioned at delivery port 08 under.
The present invention of being as shown in Figure 2 is a kind of to utilize the pass water programme diagram of the kettle seat that the center of gravity principle of transfer closes water automatically, explains that it closes water principle automatically is to utilize kettle 03 water inlet, and the lower front of kettle 03 and kettle seat board 07 has valve handgrip 021 to support; The rear portion has center of gravity positioning table 051 to support; Kettle 03 hypsokinesis a little, kettle 03 center of gravity on the kettle seat board 07 drops on the center of gravity positioning table 051, kettle 03 because of certain water level of intaking after; Change with center of gravity positioning table 051 original center of gravity relation; Generation by after the inertia that shifts forward, when kettle 03 center of gravity is transferred to front end fully, kettle 03 is unbalance; Depress the valve handgrip 021 of kettle seat board 07 below synchronously in company with kettle seat board 07 moment that turns forward, till the water of automatic pass.The 1st program that valve is closed in its kettle water filling is the water filling of taking a seat of empty kettle, and it is one in front and one in back corresponding each other with anterior valve handgrip 021 position to be positioned at the latter half of center of gravity positioning table of kettle seat 051, keeps the poised state before valve 02 is closed in kettle 03 water filling, center of gravity after.The 2nd program rises to the center of gravity transition altitude for the kettle water level, kettle 03 center of gravity by after move to front end, 03 moment of kettle is unbalance, kettle seat board 07 forms low early and high after, driven in synchronism valve handgrip 021 downward valve-closing.Each operation all must just can be opened valve 02 water filling by rotating switch knob 022, after kettle 03 water filling arrives preset height of water level, utilizes the transfer of kettle 03 center of gravity to accomplish and closes water automatically.
