The invention discloses a liquid dispensing device and a clothes processing device having the same. The liquid dispensing device comprises: a casing, a cavity is defined inside the casing, and the cavity has a first liquid inlet, a second liquid inlet, a first liquid outlet The mouth and the second liquid outlet; the elastic diaphragm, the elastic diaphragm is arranged in the cavity to divide the cavity into the first sub-cavity and the second sub-cavity, the first liquid inlet and the first liquid outlet are respectively connected with the first The sub-cavity is connected, the second liquid inlet and the second liquid outlet are respectively connected with the second sub-cavity, the flow area of the second liquid outlet is smaller than the flow area of the second liquid inlet, and the elastic diaphragm is between the elastic force and the second liquid outlet. The liquid entering the second sub-chamber can be elastically deformed under the pressure to change the volume of the first sub-chamber; the liquid inlet valve and the liquid outlet valve, the liquid inlet valve and the liquid outlet valve are respectively arranged at the first liquid inlet and the first liquid outlet At the mouth, the liquid inlet valve and the liquid outlet valve are respectively one-way valves. The liquid dispensing device according to the invention can realize quantitative dispensing, has good dispensing effect, relatively simple structure, low cost and high dispensing accuracy.
Description
technical field [0001] The present invention relates to the technical field of laundry treatment, and more specifically, to a liquid delivery device and a laundry treatment device having the same. Background technique [0002] With the improvement of the automation level of washing machines, more and more washing machines have added an automatic feeding function. In the related art, the automatic feeding of some washing machines realizes the feeding of detergent through an electric pump, but the cost of this feeding method is too high. Also some washing machines adopt Venturi principle to realize the automatic injection of detergent, but the injection accuracy is not high. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, the present invention proposes a liquid dispensing device, which has low cost and good dispensing effect. [0004] The present invention also...
