[0002] An overhead shower is a shower device that is usually installed on the ceiling of the shower room. Overhead showers have a large water spray area, which can evenly wet the whole body and avoid the discomfort caused by direct impact on the skin. In addition, the water jet is strong, which can bring a more comfortable feeling when showering.

[0003] In related technologies, overhead shower heads have multiple spray holes evenly distributed. Due to the poor water quality nowadays, scale easily precipitates when water is heated to a certain temperature. After water passes through the overhead shower head, scale accumulates in the spray holes, causing blockage. To prevent blockage, a descaling plate with descaling needles is installed inside the overhead shower head, which is manually adjusted for descaling.

[0038] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0039] In the related art, the top spray shower head is uniformly distributed with multiple spray holes 15. Due to poor water quality, scale is easily separated out after the water is heated to a certain temperature. After the water passes through the top spray shower head, the scale will accumulate in the spray holes 15, causing the spray holes 15 to be blocked. In order to prevent the spray holes 15 from being blocked, a descaling plate 2 with descaling needles 21 is arranged inside the top spray shower head, and descaling is performed by manually rotating.

[0040] However, since the top spray shower is arranged at a high position in the shower room, it is difficult for a hand to reach or it is difficult to reach, and the fixed pipe of the top spray shower is a cantilever structure. During manual operation, the fixed pipe of the top spray shower head is easily bent, the shower head is easily detached, and other damage problems occur.

[0041] Therefore, the present application provides a top spray shower head and a shower device to avoid the damage problem of the top spray shower head during descaling.

[0042] The embodiments of the present application will be described below in conjunction with Figures 1 to 7 .

[0043] According to the embodiments of the present application, on the one hand, a top spray shower head is provided, as shown in Figure 1 and Figure 2 , comprising a head body 1, a descaling plate 2 and a reset component 3. The specific scheme is as follows.

[0044] As shown in Figure 2 , the head body 1 is a plastic part, a partition plate 11 is arranged in the head body 1 to form a spray cavity 12 and a water inlet passage 13, a spray part 14 is arranged on the head body 1, multiple spray holes 15 are arranged on the spray part 14, each spray hole 15 is in communication with the spray cavity 12 for spraying water in the spray cavity 12 to wash, and a ring sleeve part 16 is arranged in the head body 1.

[0045] Specifically, the partition plate 11 can be an integral molding structure with the head body 1, such as being integrally molded by injection molding; the shape of the spray part 14 can be one of a circular shape, a rectangular shape and the like; preferably, the multiple spray holes 15 are uniformly distributed on the spray part 14; and the size of the spray hole 15 can be set according to requirements.

[0046] As shown in Figure 2 and Figure 5 , the descaling plate 2 is a plastic part, the descaling plate 2 is arranged in the spray cavity 12 and can reciprocally slide along the axial direction of the spray hole 15, multiple descaling needles 21 are arranged on the surface of the descaling plate 2 facing the spray part 14, the multiple descaling needles 21 are an integral molding structure with the descaling plate 2, the multiple descaling needles 21 correspond to the multiple spray holes 15 one by one along the axial direction of the spray hole 15, and can reciprocally move in and out of the spray hole 15 with the descaling plate 2, so that the descaling needle 21 moves in and out of the spray hole 15 to dredge the spray hole 15.

[0047] Specifically, the spray hole 15 is a conical hole, and the descaling needle 21 is a conical body and is adapted to the spray hole 15. Of course, the spray hole 15 can also be other shapes, such as a circular hole, an elliptical hole, etc. Of course, the descaling needle 21 can be a shape that is adapted to the spray hole 15.

[0048] As shown in Figure 2 , the descaling plate 2 is provided with a driving part 22, the driving part 22 is in sliding sealing connection with the ring sleeve part 16 along the axial direction of the spray hole 15 to form a driving cavity 5, the driving cavity 5 is in communication with the water inlet channel 13, and the driving part 22 can move away from the spray part 14 under the thrust of the water inlet; the communication part 4 can communicate the driving cavity 5 and the spray cavity 12 after the driving part 22 moves away from the spray part 14.

[0049] Specifically, the driving part 22 and the ring sleeve part 16 are in sliding sealing connection through a sealing member (such as a rubber ring), and the sliding sealing connection can also be realized by reducing the gap between the driving part 22 and the ring sleeve part 16.

[0050] As shown in Figure 2 , the reset component 3 is arranged in the spray head body 1 to make the descaling plate 2 have a tendency to move towards the spray part 14; specifically, the reset component 3 is an elastic member with an elastic extension amount, such as a spring, elastic rubber, etc.; the reset component 3 is arranged at different positions in the spray head body 1 to make the descaling plate 2 reset through a compressed elastic force or a stretched contraction force.

[0051] In the specific use process, as shown in Figure 2 , when the water inlet channel 13 is not supplied with water, the descaling plate 2 is under the action of the reset component 3, and the descaling needle 21 enters the spray hole 15, so that after the water inlet channel 13 is supplied with water for bathing, the water in the water inlet channel 13 enters the driving cavity 5 to push the driving part 22 to move away from the spray part 14, and drive the descaling plate 2 to move away from the spray part 14, so that the descaling needle 21 moves out of the spray hole 15; at the same time, the water in the water inlet channel 13 is supplied to the spray cavity 12 to be sprayed out of the spray hole 15 to supply a person for bathing.

[0052] After the bathing is stopped, the water inlet channel 13 stops supplying water, so that the pressure acting on the driving part 22 decreases, and the driving part 22 or the descaling plate 2 resets under the action of the reset component 3, the descaling plate 2 moves towards the spray part 14, and the descaling needle 21 reenters the spray hole 15 to dredge the spray hole 15.

[0053] In this embodiment, as shown in Figure 2As shown, by setting the partition 11 in the spray head body 1, the spray cavity 12 and the water inlet channel 13 are formed, the descaling plate 2 is slidably arranged in the spray cavity 12 along the axis of the spray hole 15, the descaling needle 21 is arranged on the descaling plate 2, the ring sleeve part 16 arranged in the spray head body 1 is in sliding sealing sleeve connection with the driving part 22 arranged on the descaling plate 2 to form the driving cavity 5, at the same time, the driving cavity 5 is in communication with the water inlet channel 13, so that the driving part 22 can reciprocate under the action force of the water pressure in the water inlet channel 13 and the reset action force of the reset part 3 to make the descaling needle 21 on the descaling plate 2 reciprocate into the spray hole 15 to dredge the spray hole 15, thereby realizing automatic descaling without manual descaling by people to avoid the problem of bending the fixed pipe of the top spray shower head or the top spray shower head falling off and being damaged by artificial operation.

[0054] In one embodiment, the communication part 4 can communicate the driving cavity 5 and the spray cavity 12 after the driving part 22 moves away from the spray part 14.

[0055] In the specific use process, as shown in Figure 2 When the water inlet channel 13 is not in water, the descaling plate 2 makes the descaling needle 21 enter the spray hole 15 under the action force of the reset part 3, so that after the water inlet channel 13 is in water for bathing, the water in the water inlet channel 13 with pressure enters the driving cavity 5 to push the driving part 22 to move away from the spray part 14, drive the descaling plate 2 to move away from the spray part 14, so that the descaling needle 21 moves out of the spray hole 15; at the same time, the communication part 4 can communicate the driving cavity 5 and the spray cavity 12 after the driving part 22 moves away from the spray part 14, so that the water in the water inlet channel 13 is sprayed out of the spray hole 15 after passing through the driving cavity 5 and the spray cavity 12 in sequence to supply people for bathing.

[0056] In one specific embodiment, as shown in Figure 2As shown, the annular sleeve 16 is an annular groove with one open end, and is disposed within the water inlet channel 13. A through hole 111 is provided on the partition plate 11. The drive unit 22 includes a piston 221 and a connecting cylinder 222. The cross-sectional area of ​​the outer side of the connecting cylinder 222 is smaller than the cross-sectional area of ​​the piston 221. Specifically, the piston 221 is a cylinder, preferably with a sealing ring on its side, which is specifically a rubber ring. The piston 221 is slidably sealed within the annular sleeve 16. The connecting cylinder 222 passes through the through hole 111, and both ends of the connecting cylinder 222 are connected to the piston 221 and the descaling plate 2, respectively. The connecting cylinder 222 and the through hole 111... 1.

Of course, in order to prevent water leakage from the drive chamber 5 into the spray chamber 12, the smaller the gap, the better. The space between the connecting cylinder 222 and the inner wall of the ring sleeve 16 is the drive chamber 5. The space formed by the annular groove and the piston 221 is not connected to the water inlet channel 13. The connecting cylinder 222 is connected to the spray chamber 12.

[0058] Specifically, the liquid permeation hole is located on the side wall of the connecting cylinder 222 near the descaling plate 2. As the drive unit 22 moves away from the spray unit 14 under water pressure, the liquid permeation hole enters the drive chamber 5 along with the connecting pipe 23 to connect the drive chamber 5 and the connecting cylinder 222, thus easily achieving the connection between the drive chamber 5 and the spray chamber 12.

[0059] More specifically, the number of liquid permeation holes can be set to multiple, evenly distributed around the circumference of the connecting cylinder 222.

The connecting cylinder 222 is provided with a liquid permeation hole. After the piston 221 moves away from the spray unit 14 under the action of water pressure, the liquid permeation hole enters the water inlet channel 13 to connect the water inlet channel 13 and the spray chamber 12. The structure is simple and easy to implement.

[0065] Specifically, the cross section of the sleeve portion 16 and the driving portion 22 can be any one of a circular ring, a rectangular ring, a polygonal ring, and an irregular ring. Of course, the shape of the sleeve portion and the driving portion 22 should be matched. Preferably, the cross section of the sleeve portion 16 and the driving portion 22 can be a circular ring.
