Description
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 inlet according to the negative pressure, and more specifically is the negative pressure that pump work was taken water and is produced opens the switch of rivers water inlet through the lever.
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 required 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 automatic opening system has high structural requirement, complex structure and high cost.
Disclosure of Invention
The utility model aims at providing a mechanism that negative pressure control lever opened the water inlet according to the pump extraction production, this mechanism no longer needs the supply of electricity, and can utilize the negative pressure to work to realize opening the water inlet automatically.
The purpose of the utility model is realized by the following scheme:
the utility model provides a mechanism that negative pressure control lever opened water inlet that produces is got according to the pump, which comprises a housin, wherein, the casing is opened there is the water inlet, water passageway and delivery port, the characteristics are, the lever sets up inside the casing, the shutoff piece that is used for sealing the water inlet is equipped with to lever first end, lever second end is equipped with the spring, make the shutoff piece plug up the water inlet by the spring action lever of spring, the inside elastic diaphragm that still is provided with of casing, the elastic diaphragm is with the water inlet, water passageway and delivery port seal, and the elastic diaphragm is towards lever second end, the elastic diaphragm receives the negative pressure effect shrink can overcome the elasticity messenger lever reversal of spring and lets the shutoff piece leave the water inlet.
Like this, the mechanism can be arranged in between storage water tank and the pump, by its water inlet and storage water tank connection, its delivery port is connected with the pump, in case the during operation of pump, will produce the negative pressure in delivery port department, so, elastic diaphragm receives the negative pressure effect will take place deformation and shrink, and act on lever second tip, can overcome spring force, make lever second tip pressurized, thereby make the lever rotate, the shutoff piece of its first tip leaves the water inlet, at this moment, water alright follow the water inlet and flow by the delivery port through the water passageway, realize the effect of automatic opening water inlet.
In addition, when the pump stops working, negative pressure is not generated any more, at this moment, the elastic diaphragm restores to deform, and meanwhile, the spring acts on the second end part of the lever to enable the lever to rotate reversely again, so that the water inlet is sealed by the plugging piece at the first end part, and the water inlet can be closed under the condition that the pump does not work.
The mechanism provided by the invention utilizes the negative pressure generated by the pump to control the plugging piece, fully utilizes the action of the pump, does not need to be specially provided with a circuit for control and coordination, does not need to provide a power supply for the circuit, and has the advantages of simple structure and lower cost.
The utility model discloses a mechanism, negative pressure are through diaphragm effect lever control shutoff piece and break away from, can make the shutoff piece obtain great turning moment, and the shutoff piece is located to break away from its action from the water inlet and will be more crisp, can ensure that the water inlet is opened completely.
This negative pressure according to pump extraction production controls the mechanism that the lever opened the water inlet, and the spring can stop producing the negative pressure after the pump through acting on lever second tip, with the lever reversal once more to make the shutoff piece of first tip can seal the water inlet, ensure that the water inlet can be closed under the inoperative condition of pump.
Therefore, the mechanism which can open the water inlet along with the starting of the pump and close the water inlet along with the closing of the pump is obtained, and the mechanism can realize the automatic opening and the automatic closing of the water inlet.

FIG. 2 is an exploded view of the components of the embodiment of FIG. 1;
fig. 3 is a schematic diagram of a cross-sectional view of the embodiment of fig. 1 in an open state.
Detailed Description
The following detailed description of specific embodiments of the present invention is made with reference to the accompanying drawings:
referring to fig. 1 to 3, the mechanism for controlling a lever to open a water inlet according to a negative pressure generated by pumping of a pump according to the present embodiment includes a lower housing 1 and an upper housing 2, wherein the lower housing 1 is provided with a water inlet 11, a water passage 12 and a water outlet 13, the lever 3 is disposed in the lower housing 1 and mounted on a lever fixing member 33, a first end 31 of the lever 1 is provided with a blocking member 4 for blocking the water inlet 11, a second end 32 of the lever 1 is provided with a spring 5, the lever 3 is acted by an elastic force of the spring 5 to enable the blocking member 4 to block the water inlet 11, the lower housing 1 is further provided with an elastic diaphragm 6, the elastic diaphragm 6 seals the water inlet 11, the water passage 12 and the water outlet 13, and the elastic diaphragm 6 faces the second end 32 of the lever 3, and the elastic diaphragm 6 contracts under the negative pressure to overcome the elastic force of the spring 5 to enable the lever 3 to rotate reversely to enable the blocking member 4 to leave the water inlet 11. Thus, the purpose of the utility model can be realized.
Claims (1)
1.
