[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0029] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0030] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0031] Referring to the drawings of the specification, a hand-held shower with a descaling function includes a water outlet body 20 that can rotate relative to the main body 10. The water outlet body includes the functions of water diversion and water discharge. A water inlet chamber 21 and a water outlet chamber 22 are provided in the water outlet body. A water diversion plate 23 is provided between the water inlet chamber and the water outlet chamber. The water diversion plate is provided with a water inlet hole 231 and a connecting hole 232. A movable piston 30 is provided at the water inlet chamber. The piston 30 can affect the water inlet effect of the water inlet hole, realize the flow limiting of the water inlet hole, and can also be blocked. It also includes a first spring 31 that can drive the piston upward. When no water enters the water inlet chamber or is not handled In the descaling state, the first spring pushes up the piston, so that the water inlet hole is a smooth passage; a movable plate 40 is provided in the water outlet chamber, and a pin 41 is provided below the movable plate, and the pin can be inserted into the water outlet hole 27 of the water body. When the pin is inserted into the water outlet hole, it is in the descaling state. A connecting column 42 that can cooperate with the connecting hole is provided above the movable plate, and it also includes a second spring 43 that can drive the movable plate to move up. Similarly, when there is no water in the water inlet chamber or it is not in the descaling state, the movable plate is pushed up under the action of the second spring, and the pin is not inserted or not fully inserted into the water outlet hole.

[0032] Preferably, the connecting column can extend through the connecting hole into the water inlet chamber. When the piston limits the flow of the water inlet, that is, when the piston moves downward against the inclined surface of the body, the water pressure in the water inlet chamber can act on the pressure surface 421 at the upper end of the connecting column. At this time, the force of the water pressure can drive the movable plate to overcome the second spring and move downward. The second spring is compressed, so that the pin is inserted into the water outlet hole, which is in a descaling state. The second spring is set in the connecting column, and a water passage 45 is formed between the connecting column and the connecting hole. The water in the water outlet chamber flows out of the water outlet hole through the water passage. At the same time, a water outlet 44 is arranged on the movable plate to allow the water in the water outlet chamber to quickly flow out of the water outlet hole. The setting of the water outlet allows the movable plate to form a mesh, which facilitates the circulation of water.

[0033] Furthermore, one end of the piston can be adapted to the water inlet, and the outer periphery of the lower end of the piston can cooperate with the water inlet to limit the water flow from the water inlet chamber into the water outlet chamber. The other end of the piston can extend to the outside of the water outlet. The main body is also provided with an inclined surface 11. The rotation of the water outlet relative to the main body can cause the other end of the piston to move downward by cooperating with the inclined surface. In other words, the inclined surface can press the piston to move downward through the cooperation with the end of the piston extending out of the water outlet, thereby limiting the flow of the water inlet. Below the inclined surface is a plane, which keeps the piston in a compressed state. The outer periphery of the piston is provided with a sealing ring 32, and one end of the piston can be inserted into the water inlet. A bracket 233 is provided in the water inlet. The first spring is provided between the bracket and the piston. The sealing ring can prevent water from leaking from the non-water outlet of the water outlet.

[0034] Furthermore, it also includes a water channel body 50, which can be fixed in the body. The water flow in the water channel body can communicate with the water inlet cavity. The water inlet of the water channel body is used to connect with the cartilage for water intake. The end surface of the water outlet body facing the water channel body is provided with multiple water inlets 24, at least one of which can communicate with the water channel body. Normally, each water inlet has a corresponding function, such as shower water, strong water, pulse water, descaling, etc.

[0035] In one embodiment of the present invention, two adjacent water inlets can be connected to the water inlet cavity, that is, the two water inlets enter the same water inlet cavity. When one of the two water inlets is connected to the water channel body, the piston limits the flow of the water inlet hole, which is a normal water outlet state, and can be used for shower water. When the other of the two water inlets is connected to the water channel body, the piston moves downward to limit the flow of the water inlet hole. The water pressure in the water inlet cavity can cause the movable plate to move downward, allowing the pin to be inserted into the water outlet hole. At this time, the shower water outlet hole is descaling. Similarly, the other water inlets also have corresponding other water outlet cavities and other water outlet holes in the water outlet body, which are basically consistent with the water flow of existing rotary switching shower heads. They will not be elaborated on in detail here. Compared with functional water, the number of water inlets is one more than the number of functional water.

[0036] Preferably, the main body is provided with a groove 12 with an opening toward the water outlet, and a matching marble 13 and spring 14 are provided in the groove. The end surface of the water outlet facing the main body is provided with a gear groove 25, and the marble can be inserted into the gear groove. When the water outlet adjusts from one gear groove to another, the functional water is switched, and the waterway body is also rotated from one water inlet to another to pass water. The number of the gear grooves is not greater than the number of water inlets, and the gear grooves can be distributed in an arc shape on the end surface of the water outlet facing the main body. Of course, there are limit blocks 26 at both ends of the gear grooves to limit the angle of rotation of the water outlet relative to the main body.

[0037] Specifically, the present invention applies a piston-type descaling component to a shower head. The component consists of a water-dividing plate, a piston, a spring for resetting, and a movable plate. With a small number of parts and a simple structure, it can be achieved under low water pressure conditions that the user only needs to use a small external force to move the water outlet to the descaling gear to realize automatic descaling of the shower head. The implementation scheme is as follows: 1. A piston is movably assembled in the body. In the initial state where the water outlet has not been moved to the descaling gear, the piston is pushed away from the main water inlet path of the water-dividing plate by the action of the first spring, that is, pushed away from the water inlet hole. At this time, the main water inlet path of the water-dividing plate is in an open state; 2. A movable plate for descaling is also movably assembled in the body. The movable plate is characterized in that it has a plurality of convex pressure-bearing surfaces and a corresponding number of corresponding connecting holes. In the initial state, the movable plate is acted upon by the second spring, and the pressure-bearing surface is at the upper limit position relative to the water-dividing plate, and the gap between the connecting column and the connecting hole is a second After the water flow of the water channel body is closed, the movable plate is reset upward under the action of the second spring, and the reset of the piston can only be achieved by rotating the water outlet body.

[0038] The foregoing description shows and describes preferred embodiments of the present invention. As previously mentioned, it should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the present invention as taught herein or through the techniques or knowledge of the relevant art. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be protected by the claims appended hereto.
