Description

Technical Field

[0001] The utility model relates to the technical field of kitchen and bathroom, in particular to an automatic descaling shower head. Background Art

[0002] After long-term use, the water output of a shower head will decrease due to the accumulation of scale. For this reason, many automatic descaling shower heads are available on the market, and most of these shower heads use a movably installed descaling panel. By utilizing the reset force of water and a spring, the panel can be reciprocated to insert the descaling needle on the front into the first water outlet of the shower head, thereby achieving the effect of automatic descaling with the help of water. However, this type of shower head requires the additional installation of a complex descaling component, which increases the cost and selling price of the shower head, making it difficult for consumers to accept. Therefore, the present invention provides a descaling shower head with a simple structure, low cost and strong descaling ability to solve the above technical problems. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a descaling shower head with a simple descaling structure.

[0004] An automatic descaling shower head includes a shower head body and a descaling water outlet panel, wherein:

[0006] The descaling water outlet panel includes a panel body and a rubber layer. Specifically,

[0007] The panel body is made of a hard material and is provided with a through hole, while the rubber coating is made of an elastic soft rubber material and is covered on the outside of the panel body by rubber coating. The rubber coating also covers the peripheral wall of the through hole and forms a water outlet channel in the through hole for the shower head to discharge water. The water outlet channel also extends out of the through hole and forms a bulge on the outward side of the panel body. A first water outlet nozzle is provided at the end of the bulge. The first water outlet nozzle is a constricted mouth and is in a straight line shape. When in use, when the water outlet channel is in a water flow state, the first water outlet nozzle deforms and expands under the action of water pressure, and elastically recovers after the water is cut off. Through elastic expansion and contraction, on the one hand, the accumulation and adhesion of scale can be avoided. On the other hand, the first water outlet nozzle will automatically expand and contract under the action of water force, which can separate, loosen and fall off the scale that has been attached or stuck from the inner wall of the water outlet channel, thereby achieving automatic descaling.

[0008] The automatic descaling shower head provided by the utility model is provided with an elastic and protruding water outlet nozzle, which can be deformed under the action of water force and restored when the water is turned off, so that the water outlet nozzle can be zoomed in and out by utilizing water force, and the descaling function is realized by the zooming action, and the descaling effect is good. Compared with other descaling components and structures, the automatic descaling shower head provided by the utility model has the advantages of simple structure and low cost, and can provide consumers with high-quality and low-cost products with good market competitiveness.

After the descaling water outlet panel is installed in the opening of the installation cavity, the end of the annular enclosure presses against the inner side surface of the descaling water outlet panel, and forms a first sealing structure by pressing the rubber layer, which can prevent water leakage from the shower head.

[0011] Preferably, an annular docking ring is provided on the inner side of the descaling water outlet panel, the annular docking ring is close to the outer periphery of the annular enclosure, and a second sealing structure is provided between the annular docking ring and the annular enclosure, which can improve the installation sealing degree of the descaling water outlet panel.

The screw passes through the mounting hole of the water outlet seat on the side of the installation cavity provided with the sealing cover and is screwed into the screw hole of the descaling water outlet panel, so that the descaling water outlet panel and the water outlet seat can fit tighter, and the sealing performance of the first sealing structure is better.

[0016] Preferably, the water outlet seat is provided with a first water flow channel and a second water flow channel, the water outlet includes a first water outlet and a second water outlet, and the descaling water outlet panel also includes a second water outlet nozzle. The first water flow channel is connected to the first water outlet nozzle through the first water outlet, and the second water flow channel is connected to the second water outlet nozzle through the second water outlet. The handle position of the shower body is provided with a water diversion chamber and a water inlet channel. The water diversion chamber is provided with a switching component.

Compared with other descaling components and structures, the utility model has the advantages of simple structure and low cost, and can provide consumers with a high-quality and low-cost product with good market competitiveness.

[0021] The straight-line first water outlet is more easily deformed under the impact of water flow, and the deformed shape is quite different from the original shape. Therefore, after the scaling action, the scale can be separated, loosened and detached, achieving a better descaling effect.

[0022] Multiple sets of sealing structures are set up to greatly improve the sealing performance of the shower head, while no additional sealing rings are required. The structure is streamlined, with fewer parts and easy to assemble;
