Description

Mechanism for opening water channel according to negative pressure

Technical Field

The utility model belongs to a controlling means of feedwater among domestic appliance relates to one kind and opens the mechanism of water passageway according to the negative pressure, and more specifically is the negative pressure that pump work was taken water and is produced and drive the switch that the shutoff piece breaks away from in order to open the water passageway through elastic diaphragm effect linkage piece.

Background

In the existing tea making device, a water storage tank and a water inlet mechanism are arranged, and because the water storage tank is usually arranged below, a pump is needed to pump water from the water storage tank to the water inlet mechanism so as to send the water to a kettle by the water inlet mechanism.

Generally, the water inlet mechanism is provided with a valve for controlling water inlet, and the opening mode of the valve is divided into manual and automatic modes. The automatic opening is generally controlled by electricity, and meanwhile, an electronic circuit is required to coordinate the valve and the pump, so that the requirement on a water inlet mechanism is high, the structure is complex, and the cost is high.

Disclosure of Invention

The utility model aims at providing a mechanism for opening water passageway according to negative pressure, this mechanism no longer need the supply of electricity, and can utilize the negative pressure to work to realize opening the passageway of water automatically.

The purpose of the utility model is realized by the following scheme:

a mechanism for opening a water channel according to negative pressure comprises a shell, wherein a controlled piece is arranged in the shell, a water inlet and a water outlet are formed in the side surface of the controlled piece, a through hole is formed in the middle of the controlled piece, the water inlet is communicated with the lower portion of the controlled piece, and the water outlet is communicated with the through hole; the method is characterized in that: the sealing device also comprises a fixing part, a first elastic membrane, a second elastic membrane, a linkage part, a blocking part and a spring which are arranged in the shell, wherein the first elastic membrane and the fixing part are positioned below the controlled part, and the second elastic membrane is positioned above the controlled part; the fixing piece is provided with a middle column hole and a peripheral column hole, the positions of the first elastic membrane corresponding to the middle column hole and the peripheral column hole are respectively provided with a hole position, and the first elastic membrane is sleeved on the fixing piece so that the middle column hole and the peripheral column hole respectively extend out of the corresponding hole positions; the upper part of the middle column hole of the fixing piece can be sleeved on the lower part of the through hole of the controlled piece; the plugging piece is provided with a spring, and the spring enables the plugging piece to move upwards and prop against the lower part of the middle column hole of the fixing piece so as to seal the middle column hole; the linkage piece penetrates through the through hole and the middle column hole from top to bottom and extends downwards to act on the blocking piece, and the blocking piece can be separated from the middle column hole by overcoming a spring so that the middle column hole is communicated with the lower part of the fixing piece; the second elastic diaphragm is positioned on the linkage piece, the lower part of the linkage piece can be sealed by the second elastic diaphragm, and the linkage piece can contract downwards under the action of negative pressure to enable the linkage piece to overcome the spring to separate the blocking piece from the middle column hole; each part is fixed by the shell, and the through hole is upwards sealed by the first elastic membrane under the action of the spring through the sealing piece.

Thus, when the water outlet has no negative pressure, water can enter from the water inlet and enter the lower part of the fixing piece through the peripheral column holes, and the spring can enable the plugging piece to jack up upwards and seal the middle column hole, so that the middle column hole is not communicated with the lower part of the fixing piece; when negative pressure exists at the water outlet, the second elastic membrane deforms and contracts downwards and acts on the linkage piece, so that the linkage piece overcomes the spring to enable the plugging piece to move downwards to leave the middle column hole, then the middle column hole is opened to be communicated with the lower part of the fixing piece, and water flows out of the water outlet through a gap between the middle column hole and the linkage piece.

In addition, when negative pressure exists at the water outlet, water flows through a gap between the middle column hole and the linkage piece and flows out of the water outlet, pressure of water entering from the water inlet is released, the water flow acts downwards on the first elastic membrane to enable the first elastic membrane and the fixing piece to move downwards together to enable the middle column hole to leave the through hole, and therefore the water entering from the water inlet can directly flow to the water outlet from the through hole, and the requirement for rapid water supply is favorably met.

Moreover, when the delivery port no longer has the negative pressure, the deformation will be resumeed to the second elastic diaphragm, and the spring will make shutoff piece and linkage piece rebound and closed the middle post hole by the shutoff piece, and at this moment, the water that gets into from the water inlet can continue to get into the mounting below through peripheral post hole to form the water pressure below the mounting, this water pressure can be acted on mounting and first elastic diaphragm with shutoff piece and spring together, makes first elastic diaphragm upwards paste with controlled piece through-hole tighter, is favorable to further improving the sealed of water.

Thus, the mechanism can be arranged between the water storage tank or the tap water pipe tap and the pump, the water inlet of the mechanism is connected with the water storage tank or the tap water pipe tap, the water outlet of the mechanism is connected with the pump, negative pressure can be generated at the water outlet by pumping of the pump, so that the water channel can be opened along with the starting of the pump, the water channel is closed along with the closing of the pump, and the automatic opening and the automatic closing of the water channel can be realized.

The invention creates a mechanism for opening the water channel according to the negative pressure, utilizes the negative pressure generated by the pump to open the water channel, fully utilizes the action of the pump, does not need to be specially provided with a circuit, does not need to provide a power supply for the circuit, can control the opening and closing of the water channel through the second elastic diaphragm, the linkage piece, the spring and the blocking piece, and has the advantages of simple structure and low cost.

The utility model discloses open the mechanism of water passageway according to the negative pressure, the delivery port no longer has the negative pressure, and the shutoff piece will the rebound and seal the middle post hole, and at this moment, the water that gets into from the water inlet can get into the mounting below through peripheral post hole to at the mounting below formation water pressure, this water pressure can be acted on mounting and first elastic diaphragm, makes its rebound and with receive the controlling part to paste tighter, is favorable to further strengthening the sealed to water.

According to the mechanism for opening the water channel according to the negative pressure, when the negative pressure exists at the water outlet, the plugging piece moves downwards to enable the middle column hole to be communicated with the lower part of the fixing piece, water flows to the water outlet through the middle column hole to enable the water at the lower part of the fixing piece to be released, at the moment, the fixing piece and the first elastic membrane can be pressed downwards by water entering from the water inlet to enable the fixing piece and the first elastic membrane to leave the controlled piece, and therefore the entering water can directly flow to the water outlet through the through hole, the purpose that the smaller negative pressure can be generated by adopting smaller power, and the water channel of the larger channel can be opened to quickly meet the supply of larger water quantity is achieved.
