[0042] See also Figures 1 to 8 , Figures 1 to 8 The descaling shower provided in this embodiment comprises a body 1, a descaling frame 10, a driving assembly 17, a second reset member 25, a decorative cover 26, a screw connection member 27 and a spherical water inlet joint.

[0043] The body 1 has a water inlet hole and a water outlet cavity with a water outlet hole 8. In addition, in this embodiment, the body 1 also has a water inlet channel 4 connected between the water inlet hole and the water outlet cavity; the water inlet channel 4 extends along the first direction, and the water inlet end 5 is located at one end thereof. Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the body 1 in this embodiment is introduced as a top-spray type body 1 structure, which has a central axis, and includes a water inlet cover 2 and a water outlet surface cover 7. The water inlet cover 2 is a circular cover structure, which has a vertically extending water inlet hole. In the example given in this embodiment, the water inlet hole constitutes a water inlet end 5 of the water inlet channel 4. Specifically, an annular wall 3 extending downward from its top surface is provided at the central axis of the water inlet cover 2, that is, an annular wall 3 extending along the water outlet direction (that is, the final water outlet direction of the body 1) is provided in the middle of the body 1, and the channel enclosed by the annular wall 3 constitutes the water inlet channel 4. It can be seen from this that the first direction is parallel to the water outlet direction of the water outlet hole 8 and the water inlet channel 4 is provided at the central axis of the body 1, but it should be understood that The first direction may also be a horizontal direction or other direction inclined relative to the vertical direction. The direction setting only needs to ensure that the movement of the driving assembly 17 in the water inlet 4 can make the two magnetic elements (refer to the first magnetic element 23 and the second magnetic element 16 below) approach or move away from each other; the end of the annular wall 3 away from the descaling rack 10 is open and constitutes the water inlet end 5 of the water inlet 4, that is, the position of the water inlet hole, and the end close to the descaling rack 10 is closed, and its side wall is provided with an opening for constituting the water outlet end 6 of the water inlet 4, refer to Figure 3As shown, in this embodiment, the water outlet end 6 of the water inlet 4 is opened on the side wall of the annular wall 3 and extends to the closed end, but is not completely arranged on the closed end, so that the drive assembly 17 can easily open and close the water outlet end 6 of the water inlet 4 when sliding in the water inlet 4; in order to improve the water outlet efficiency, the side wall of the annular wall 3 can preferably be provided with two or more openings. The water outlet surface cover 7 is provided at the bottom end of the water inlet cover 2, and the periphery of the two is usually fixed and sealed by welding or sealing clamping, and fixed in place, and a water outlet cavity is formed between the water outlet surface cover 7 and the water inlet cover 2, and the annular wall 3 extends into the water outlet cavity, and the water outlet end 6 of the water inlet 4 is connected to the water outlet cavity; a plurality of water outlet holes 8 are arranged on the water outlet surface cover 7, that is, the water outlet cavity has water outlet holes 8; in addition, in this embodiment, a plurality of vertically extending guide columns 9 are also provided on one side of the water outlet cavity of the water outlet surface cover 7, so as to guide the descaling rack 10.

[0044] The descaling rack 10 is slidably mounted in the water outlet cavity and has a needle portion 12. This is a prior art. Usually, the descaling of the water outlet hole 8 is achieved by inserting the needle portion 12 thereon into the water outlet hole 8, and when it is lifted and the needle portion 12 thereon is detached (including partially detached), it avoids the space inside the water outlet hole 8 and allows water to flow out. There is a problem that this embodiment intends to solve, that is, if the needle portion 12 of the descaling rack 10 cannot quickly avoid the space inside the water outlet hole 8 when water is flowing in, then the water will flow out too slowly and the user will have to wait for a long time. Figure 1 , Figure 7 and Figure 8 As shown, in this embodiment, the descaling frame 10 includes a descaling plate 11 and a second magnetic attraction member. Figure 5 As shown, the descaling plate 11 is disc-shaped, and the needle portion 12 on the side facing the water outlet 8 corresponds to the water outlet 8 one by one, and the central axis of the side away from the water outlet 8 is provided with a second installation groove 13; the groove wall of the second installation groove 13 is provided with a second convex rib 14, and when installing, the second magnetic member 16 can be pressed into the second convex rib 14 with force, which has a simple structure and convenient assembly; in addition, the descaling plate 11 is also provided with a plurality of guide holes 15, and each guide hole 15 is respectively plugged with each guide column 9 to realize the water outlet cover 7 to guide the movement of the descaling plate 11. The second magnetic member is installed in the second installation groove 13 and is restricted from being disengaged by the second convex rib 14. It is suitable for magnetic attraction with the driving assembly 17. When magnetic attraction occurs, the descaling frame 10 is lifted and the water outlet 8 is opened; when the magnetic attraction disappears, the descaling frame 10 can fall back based on its own gravity or other reset force and the needle portion 12 is re-inserted into the water outlet 8. In this embodiment, the water inlet 4 is arranged at the central axis of the body 1. When the driving member 18 and the descaling frame 10 are magnetically attracted, the descaling frame 10 is easier to maintain balance, so that the water outlets 8 can be reliably opened at the same time.

[0045] The driving assembly 17 includes a driving member 18 and a first reset member 24. The driving member 18 is slidably disposed in the water inlet 4. The driving member 18 is adapted to slide to form a magnetic effect with the descaling rack 10 based on the water pressure when water is flowing into the water inlet 4 and drive the descaling rack 10 away from the water outlet 8. The driving member 18 is also adapted to be reset by the first reset member 24 and release the magnetic effect with the descaling rack 10 when water is not flowing into the water inlet 4 to allow the descaling rack 10 to fall back and allow the needle 12 to be inserted into the water outlet 8. The first direction is arranged parallel to the water outlet direction of the water outlet 8, and the driving assembly 17 is arranged by utilizing the thickness space of the shower head. The space utilization is reasonable, and the space used to form the water outlet cavity of the body 1 can be filled more, and the body 1 can be easier to shape.

[0046] Based on this, it can be known that the water inlet hole, the water inlet channel 4 and the water outlet cavity in the body 1 are connected in sequence; the water inlet channel 4 extends along the first direction and its water inlet end 5 is located at one end thereof; in the driving assembly 17, the driving member 18 is slidably arranged in the water inlet channel 4, which is directly opposite to the water inlet end 5 of the water inlet channel 4, and the water inlet direction of the water inlet channel 4 is consistent with the sliding direction of the driving member 18. When water enters the water inlet channel 4, the inlet water flow quickly fills the water inlet channel 4 and rapidly applies pressure to the driving member 18, so that the driving member 18 can quickly respond and slide to form a magnetic effect with the descaling rack 10 and drive the needle portion of the descaling rack 10 12 opens the water outlet 8, so that the water flowing into the water outlet cavity from the water inlet 4 can quickly flow out of the water outlet 8, which can avoid the slow opening speed of the water outlet 8 of the descaling rack 10 due to the slow water pressure response speed of the driving component 17 and the long waiting time for the user to get out of the water; when the water inlet 4 is not filled with water, the water pressure disappears, and the driving component 18 is reset under the action of the first reset component 24, and the magnetic effect between it and the descaling rack 10 disappears. The descaling rack 10 can fall back based on its own gravity or other reset forces and make the needle 12 re-inserted into the water outlet 8 to achieve descaling of the water outlet 8. In this technical solution and its preferred embodiment, the descaling functional parts only have the driving component 18 and the first reset component 24, and the driving component 18 drives the descaling rack 10 to move in a magnetic way. There is no complex mechanical structure and no mechanical transmission movement. Therefore, the driving component 17 will not cause the descaling to be poor or ineffective due to the accumulation of scale, so that the product has a long service life and users can also get better satisfaction.

[0047] Specifically, Figure 1 and Figure 6As shown, the driving member 18 includes a piston 19 and a first magnetic member 23. The piston 19 is slidably disposed on the water inlet 4 and is used to block or open the water outlet 6 of the water inlet 4. In this embodiment, the side wall of the piston 19 is sealed with the inner wall of the annular wall 3, so that the driving member 18 exists in a state of isolating the water inlet 4 and the water outlet 6 of the water inlet 4 when water enters the water inlet 4, and exists in a state of opening the water outlet 6 of the water inlet 4 when water enters the water inlet 4, that is, exists in a state of opening the connection between the water inlet 4 and the water outlet 6 of the water inlet 4, so that each time the water inlet 4 enters the water inlet 4, the water flowing into the water inlet 4 acts on the driving member 18, the water pressure of the water inlet is large, and it is conducive to making the driving member 18 respond quickly to the water pressure and slide; the piston 19 is provided with a first mounting groove 20; the notch of the first mounting groove 20 is located on the end face of the piston 19, and the groove wall of the first mounting groove 20 is provided with a first rib 211. The first magnetic member 23 is fixedly connected to the piston 19 to form a magnetic effect with the second magnetic member 16 in the descaling frame 10. Specifically, it is installed in the first installation groove 20 and is restricted from coming out by the first rib 211. During installation, the first magnetic member 23 is pressed forcefully into the first rib 211. The structure is simple and the assembly is convenient. In this embodiment, the first rib 211 is annular to limit the freedom of the first magnetic member 23 in the entire circumferential direction, so that the first magnetic member 23 can reliably form a magnetic effect with the second magnetic member 16.

[0048] like Figure 1 , Figure 7 and Figure 8 As shown, the first reset member 24 is a spring but not limited to it, which is arranged vertically, and the top and bottom ends abut against the piston 19 and the closed end of the annular wall 3 respectively; when the driving member 18 moves downward under the action of the water pressure of the incoming water, the first reset member 24 is compressed to store energy; when the driving member 18 is not affected by the water pressure of the incoming water, the first reset member 24 releases energy and overcomes the magnetic effect of the first magnetic member 23 and the second magnetic member 16 to push the driving member 18 upward until the magnetic effect between the first magnetic member 23 and the second magnetic member 16 gradually disappears. In order to improve the stability of the first reset member 24, in this embodiment, the bottom surface of the piston 19 is provided with a positioning groove 22 for the top of the first reset member 24 to be placed, so as to prevent the first reset member 24 from swinging.

[0049] The second restoring member 25 acts between the body 1 and the descaling rack 10 along the water outlet direction, and is suitable for storing and releasing energy when the water inlet 4 is filled with water or not filled with water. Figure 1 , Figure 7 and Figure 8As shown, the second reset member 25 is a spring but not limited to a spring, which is arranged vertically, and the top and bottom ends thereof respectively abut against the water inlet cover 2 and the descaling plate 11, and in order to improve stability, the top of the second reset member 25 is sleeved on the outer periphery of the annular wall 3. The second reset member 25 is used to reset the descaling rack 10 when the driving member 18 is reset, so that the descaling rack 10 can reliably fall back and be inserted into each water outlet 8.

[0050] like Figure 2 , Figure 7 and Figure 8 As shown, the decorative cover 26 is provided at the top of the water inlet cover 2, which is used to improve the aesthetics. The screw connection 27 is tubular, which is screwed to the top of the water inlet cover 2 and limits the decorative cover 26 from being separated from the water inlet cover 2. The ball head of the spherical water inlet joint is inserted into the screw connection 27 and is limited by the screw connection 27 to be separated. The ball head of the spherical water inlet joint is also sealed with the water inlet 4 of the water inlet 4 through an O-ring. The decorative cover 26, the screw connection 27 and the spherical water inlet joint are all existing structures and will not be described in detail here.

[0051] The use principle of the descaling shower provided in this embodiment is:

[0052] refer to Figure 8 When the descaling shower head is filled with water, the water flows through the spherical water inlet joint and flows into the water inlet channel 4. Under the action of the water pressure, the piston 19 and the first magnetic member 23 overcome the elastic force of the first reset member 24 and move downward until the piston 19 gradually opens the water outlet end 6 of the water inlet channel 4, and the water flows from the water inlet channel 4 into the water outlet cavity. At the same time, the distance between the first magnetic member 23 and the second magnetic member 16 is shortened and magnetic attraction occurs. The descaling plate 11 overcomes the elastic force of the second reset member 25 and moves upward. The needle 12 opens the water outlet hole 8, and the water in the water outlet cavity is output from the water outlet hole 8, thereby realizing the water discharge of the descaling shower head.

[0053] refer to Figure 7 When the descaling shower head is not filled with water, the water inlet 4 stops filling with water or very little water remains, the water pressure on the piston 19 and the first magnetic member 23 disappears, the first reset member 24 resets, and pushes the piston 19 and the first magnetic member 23 to move upward. After moving up a certain distance, the magnetic attraction of the first magnetic member 23 and the second magnetic member 16 disappears, the first reset member 24 is completely reset, and at the same time, the second reset member 25 is also reset, the descaling frame 10 falls back based on its own gravity and the elastic force of the second reset member 25, and the needle portion 12 is inserted into the water outlet 8 to achieve descaling of the water outlet 8.
