Description

Mechanism for controlling closed part to open water channel according to negative pressure generated by pump extraction

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 drawn water and is produced opens the switch of water passageway through elastic diaphragm control closure member.

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 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 storage tank is provided with a valve for controlling the supply of water, and the way of opening the valve is divided into manual and automatic. 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 that negative pressure control closure part opened water passageway according to the pump extraction production, this mechanism no longer need the supply of electricity, and can utilize the negative pressure to work to realize opening water passageway automatically.

The object of the present invention can be achieved by the following first solution:

a mechanism for opening water channel by controlling the sealing part according to the negative pressure generated by pump suction is composed of a casing with water inlet and outlet on its side, a controlled part in said casing, a through hole on the top of said controlled part, a water inlet communicated with said controlled part, and a water outlet communicated with said controlled part via said through hole.

Thus, the mechanism can be arranged between the water storage tank (or tap water pipe) and the pump, and is connected with the water storage tank through the water inlet of the mechanism and connected with the pump through the water outlet of the mechanism.

When the pump works, negative pressure is generated at the water outlet, so that the elastic diaphragm deforms under the action of the negative pressure and contracts downwards, the spring is overcome to drive the sealing part to move from top to bottom to enable the sealing ring to leave the through hole, at the moment, the controlled part is communicated with the water outlet, water can flow out of the water outlet after being subjected to the control part from the water inlet, and the effect of automatically opening the water channel is realized.

In addition, when the pump stops working, the elastic diaphragm does not recover deformation under the action of negative pressure, and meanwhile, the spring recovers deformation to drive the sealing part to move from bottom to top and seal the through hole by the sealing ring, so that the controlled part is not communicated with the water outlet, and water does not flow out of the water outlet and is closed.

Preferably, in the first aspect, the chamber above the elastic membrane in the housing is provided with a gas port, the gas port can be filled with gas, and the gas pressure generated by the gas acts on the elastic membrane to also open the water channel. Thus, in use in a tea brewing device, when the pump fails, water may also be drained from the water reservoir by means of a hand-pump or the like.

The object of the utility model can be realized by the following second scheme:

a mechanism for opening water channel by the negative pressure generated by pump is composed of a casing with water inlet and outlet on its side, a controlled part in said casing, a through hole on the top of said controlled part, a water inlet communicated with said controlled part, and a water outlet communicated with said controlled part via said through hole.

When the pump works, negative pressure is generated at the water outlet, so that the elastic diaphragm deforms and contracts downwards under the action of the negative pressure, the spring is overcome to drive the sealing part to move from top to bottom and leave the through hole, at the moment, the controlled part is communicated with the water outlet, water can flow out of the water outlet after being subjected to the control part from the water inlet, and the effect of automatically opening the water channel is realized.

In addition, when the pump stops working, the elastic diaphragm is not subjected to the action of negative pressure any more and recovers deformation, and meanwhile, the spring recovers deformation and drives the sealing part to seal the through hole from bottom to top, so that the controlled part is not communicated with the water outlet, and water does not flow out of the water outlet and is closed.

Moreover, the guide rod can play a role in stabilizing and guiding the movement of the sealing part in the through hole, particularly, the sealing part cannot be twisted with the elastic membrane, and the sealing part can be always positioned on the central axis in the opening or closing process, so that the effect of matching with the through hole is better.

The mechanism provided by the invention controls the sealing part by using the negative pressure generated by the pump, 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 by the elastic diaphragm, the spring and the sealing part, and has the advantages of simple structure and lower cost.

The utility model discloses a mechanism, closed part are arranged in the through-hole that receives the controlling part, and closed part move down and make the through-hole open and utilize the negative pressure to pass through elastic membrane deformation drive, therefore closed part breaks away from its action from through-hole department and will be more crisp and steady, can ensure that the water inlet is opened completely.

According to the mechanism for controlling the sealing part to open the water channel according to the negative pressure generated by pumping, after the pump stops generating the negative pressure, the elastic diaphragm recovers deformation, the sealing part drives the sealing part or the sealing ring to seal the through hole under the action of the spring, and the water channel can be ensured to be closed under the condition that the pump does not work.

Therefore, the mechanism which can open the water channel along with the starting of the pump and close the water channel along with the closing of the pump is obtained, and the mechanism can realize the automatic opening and the automatic closing of the water channel.
