Descaling mechanism of liquid outlet device, liquid outlet device, shower head and faucet

Abstract

The invention discloses a liquid outlet device descaling mechanism, a liquid outlet device, a shower head and a faucet, the liquid outlet device descaling mechanism comprises a liquid outlet unit and a driving mechanism capable of moving relative to the liquid outlet unit, the liquid outlet unit is provided with a liquid outlet nozzle, the liquid outlet nozzle is provided with an elastic element, the elastic element is provided with a liquid outlet of the liquid outlet nozzle, and the liquid outlet nozzle is connected with the driving mechanism. The driving mechanism is matched with the elastic element and can movably drive the elastic element to elastically deform through the driving mechanism, and the elastic deformation of the elastic element can promote scaling accumulated in the liquid outlet nozzle to fall off. The descaling device has the advantages that descaling can be achieved by only driving the elastic element to deform through the driving mechanism, the requirement for the matching precision between the driving mechanism and the liquid outlet nozzle is low, and the requirement for the production precision of the driving mechanism is low; the elastic element is driven by the driving mechanism to deform, limitation of water flow conditions is avoided, and the descaling effect can be improved.

Description

technical field [0001] The invention relates to the technical field of descaling, in particular to a descaling mechanism of a liquid outlet device, a liquid outlet device, a shower and a faucet. Background technique [0002] The descaling mechanism of the existing liquid outlet device mainly contains two types. [0003] The first type of descaling mechanism includes a liquid outlet unit and a needle plate. The liquid outlet unit is provided with a liquid nozzle. The needle plate is provided with a thimble. The scale in the liquid nozzle is ejected. It has the following disadvantages: the difference between the outer diameter of the thimble and the hole diameter of the liquid outlet is strictly limited, so as to ensure that the thimble will not be wrapped by the surrounding wall of the liquid outlet and cause the phenomenon of being locked and cannot be reset, and it can also ensure that the ejection knot cannot be reset. Therefore, the processing precision of the thimble n...

It has the following disadvantages: the difference between the outer diameter of the thimble and the hole diameter of the liquid outlet is strictly limited, so as to ensure that the thimble will not be wrapped by the surrounding wall of the liquid outlet and cause the phenomenon of being locked and cannot be reset, and it can also ensure that the ejection knot cannot be reset. Therefore, the processing precision of the thimble needs to be high to ensure that there is a gap between the thimble and the liquid outlet; as mentioned above, there is a gap, so the scaling cannot be completely removed, and some scaling will remain in the gap, although it will not cause hole plugging But it will affect the shape of the liquid, such as affecting the water spray and affecting the shower experience

The scheme of using water pressure to force the deformation of the elastic element to realize descaling is highly dependent on the water pressure. Scale will cause hole blockage, reduce the liquid output or affect the liquid shape; at the design and production level, in order to ensure the descaling effect, that is, to ensure that the elastic element can be squeezed and deformed, it is necessary to reduce the number of liquid outlet nozzles, which will affect the user experience
