Description

Technical Field

[0001] This utility model relates to the technical field of shower heads, and in particular to the water outlet structure of an overhead shower head. Background Technology

[0002] When using existing overhead showerheads, the water flow from the water supply system to the showerhead stops when the user closes the valve. However, a large amount of water remains in the showerhead itself and the water pipe connected to it. This water cannot be drained instantly but drips continuously from the showerhead's outlet. Sometimes, it doesn't drip immediately but suddenly flows down in large quantities after a period of water interruption. This causes inconvenience to the user and results in a poor user experience. Utility Model Content

[0003] The purpose of this utility model is to provide a water outlet structure for a top-spray shower head, and to solve the technical problem of enabling the top-spray shower head to turn off and stop water flow immediately.

[0004] To achieve the above objectives, the solution of this utility model is: a water outlet structure for a top-spray shower head, including a housing, a water passage cavity formed inside the housing, a water outlet panel formed on the bottom wall of the water passage cavity, a water outlet provided on the water outlet panel, and the water outlet connected to the water passage cavity;

[0005] It also includes a waterstop plate, which is slidably disposed in the water passage cavity to be close to or away from the water outlet. When the waterstop plate slides down to be close to the water outlet, it is used to block the water outlet. A pressure cavity is formed between the waterstop plate and the water outlet panel. A water inlet channel is formed on the housing to guide the pressure cavity. After the water flows into the pressure cavity, the water pressure pushes the waterstop plate from the pressure cavity, causing the waterstop plate to slide down and open the water outlet. The water flows from the pressure cavity into the water outlet.

[0006] Furthermore, a first groove is formed on the waterstop plate, and a second groove corresponding to the first groove is formed on the water outlet plate. The sidewall of the first groove is a first annular sidewall, and the sidewall of the second groove is a second annular sidewall. The first annular sidewall and the second annular sidewall are nested together to form the pressure cavity between the first groove and the second groove.

[0007] Furthermore, one of the first and second annular sidewalls is connected to form a water inlet, so that when the water stop plate slides down, the first or second annular sidewall blocks the water inlet, and the water outlet is located outside the pressure chamber, so that when the water stop plate slides down, the water inlet is opened, allowing water to flow through the water inlet into the water passage chamber and out from the water outlet.

[0008] Furthermore, the first annular sidewall is fitted outside the second annular sidewall, and the second annular sidewall forms a guide arc surface at one end facing the waterstop plate.

[0009] Furthermore, the shell extends longitudinally within the water passage cavity to form a guide post, and the waterstop plate extends longitudinally to form a guide hole, through which the guide post passes, allowing the waterstop plate to slide up and down along the extension direction of the guide post.

[0010] Furthermore, the waterstop plate has reinforcing ribs on the side opposite to the water outlet panel.

[0011] Furthermore, an elastic element is provided between the waterstop plate and the shell. The elastic element is used to drive the waterstop plate to slide down, so that the waterstop plate is close to the water outlet panel.

[0012] Furthermore, a spherical joint is hinged to the shell, and a water inlet is formed through the top wall of the spherical joint, which leads to the water inlet channel.

[0013] Furthermore, the water outlet panel includes a decorative panel and a water outlet component. The water outlet component has an array of several water outlet columns, and the water outlets are penetrated through the water outlets. The decorative panel has mounting holes that cooperate with the several water outlet columns. The end of the water outlet column facing the water stop plate protrudes upward and abuts against the water stop plate. The end of the water outlet column away from the water stop plate passes through the mounting holes and extends downward out of the bottom surface of the decorative panel.

[0014] The beneficial effects of this utility model after adopting the above solution are as follows: the waterstop plate is slidably installed in the water passage cavity. When the waterstop plate slides down and approaches the water outlet, it blocks the water outlet and forms a pressure chamber with the water outlet panel. When the water flows into the pressure chamber, it instantly compresses the air in the pressure chamber, making the pressure in the pressure chamber greater than the pressure on the side of the waterstop plate away from the water outlet panel. As a result, the water pressure pushes the waterstop plate from the pressure chamber, causing the waterstop plate to slide down. When the water inlet is closed, the pressure difference disappears, and the waterstop plate falls down by gravity to block the water outlet, realizing immediate shut-off. Attached Figure Description

[0029] like Figures 1 to 9As shown, this utility model provides a water outlet structure for a top-spray shower head, including a housing 1, a water passage cavity 2 formed inside the housing 1, a water outlet panel 3 formed on the bottom wall of the water passage cavity 2, a water outlet 4 provided on the water outlet panel 3, the water outlet 4 connected to the water passage cavity 2, an opening on the bottom side of the housing 1, the water outlet panel 3 mounted on the opening of the housing 1, and the water outlet panel 3 and the housing 1 are fixed together by snap-fit, or can be fixed by other structures, without specific limitations; it also includes a water stop plate 2, which is slidably disposed in the water passage cavity 2 to approach or move away from the water outlet 4, so that when the water stop plate 2 slides down to approach the water outlet 4, the water stop plate 2 is used to block the water outlet 4, and a pressure cavity 6 is formed between the water stop plate 2 and the water outlet panel 3, and a water inlet channel 7 is formed on the housing 1 to guide the water inlet channel 6, so that after the water flow enters the pressure cavity 6, the water pressure pushes the water stop plate 2 from the pressure cavity 6, causing the water stop plate 2 to slide up and open the water outlet 4, and the water flow enters the water outlet 4 from the pressure cavity 6.

[0030] Key points combined Figures 6-9 As shown, a first groove 8 is formed on the waterstop plate 2, and a second groove 9 corresponding to the first groove 8 is formed on the water outlet plate 3. The sidewall of the first groove 8 is a first annular sidewall 81, and the sidewall of the second groove 9 is a second annular sidewall 91. The first annular sidewall 81 and the second annular sidewall 91 are nested together. The first annular sidewall 81 can be nested outside the second annular sidewall 91, or the second annular sidewall 91 can be nested outside the first annular sidewall 81; there is no specific limitation. The first annular sidewall 81 and the second annular sidewall 91 can be circular, square, polygonal, or other structures; there is no specific limitation, as long as they can fit together. When the two are nested together, the first annular sidewall 81 and the second annular sidewall 91 partially overlap; specifically, the first groove 8 is formed in the middle area of ​​the waterstop plate 5, the first groove 8 opens downward, the second groove 9 is formed in the middle area of ​​the water outlet panel 3, the second groove 9 opens upward, the first groove 8 and the second groove 9 correspond vertically, and the pressure chamber 6 is formed between the first groove 8 and the second groove 9, the top wall of the first groove 8 forms a through hole, the water inlet channel 7 extends longitudinally and is located in the center of the shell 1, the water inlet channel 7 extends downward through the through hole into the pressure chamber 6, when the water inlet channel 7 is connected to an external water source, the water flows directly into the pressure chamber 6.

[0031] In this specific embodiment, one of the first annular sidewall 81 and the second annular sidewall 91 is connected to form a water inlet 10. The water inlet 10 is located on one of the sidewalls that are nested and overlapped. When the waterstop plate 5 slides down, the first annular sidewall 81 or the second annular sidewall 91 blocks the water inlet 10. The water outlet 4 is located outside the pressure chamber 6. There are multiple water outlets 4, and multiple water outlets are arranged in annular array around the outer periphery of the pressure chamber 6 so that when the waterstop plate 2 slides up, the water inlet 10 is opened, and water flows into the water passage chamber 2 through the water inlet 10 and flows out from the water outlet 4. Figure 3As shown, the water inlet 10 is formed on the second annular sidewall 91. The top part of the second annular sidewall 91 is recessed to form the water inlet 10. There are multiple water inlets 10, which are arranged in a ring array along the second groove 9, which can quickly divert the water flow to each water outlet 4. In use, the water inlet channel 7 is connected to the external water source device. After the water flow enters the pressure chamber 6, it instantly compresses the air in the pressure chamber 6, making the pressure in the pressure chamber 6 greater than the pressure on the side of the water stop plate 2 away from the water outlet panel 3. Then the water pressure drives the water stop plate 2 to slide upward, so that the water flow enters the water passage chamber 2 from the pressure chamber 6 through the water inlet 10 and sprays out from each water outlet 4 of the water outlet panel 3. When the external water source device is turned off, the water stop plate 2 falls back by its own weight to block each water outlet 4.

[0032] In this specific embodiment, the first annular sidewall 81 is sleeved on the outside of the second annular sidewall 91. The second annular sidewall 91 forms a guide arc surface 92 at one end facing the waterstop plate 2, so that when the waterstop plate 2 slides down by its own weight, the inner side of the first annular sidewall 81 can slide down along the guide arc surface 92 and then be sleeved on the outside of the second annular sidewall 91. Of course, in other embodiments, the second annular sidewall 9 can also be sleeved on the outside of the first annular sidewall 81. For example, the first groove 8 protrudes downward and opens upward. When the second annular sidewall 9 is sleeved upward on the outside of the first annular sidewall 81, the pressure cavity 6 is formed between the bottom wall of the first groove 8 and the second groove 8. At this time, the water outlet 10 can be formed on the first annular sidewall 81 or on the second annular sidewall 91.

[0033] Key points combined Figure 5 As shown, a guide post 11 extends longitudinally on the shell 1, and a guide hole 12 extends longitudinally through the waterstop plate 2. The guide hole 12 allows the guide post 11 to pass through, enabling the waterstop plate 2 to slide up and down along the extension direction of the guide post 11. Specifically, the guide post 11 is formed on the water outlet panel 3, and then... Figure 2 and Figure 4 As shown, a fixing plate 21 is also provided inside the housing 1. The fixing plate 21 is located above the waterstop plate 2. An installation groove 22 is formed on the bottom surface of the fixing plate 21. The top of the guide post 11 is inserted into the installation groove 22 and fixed by screws. The guide post 11 is fixed along the axial direction. In addition, there are multiple guide posts 11, which are evenly distributed on the housing 1. One guide post 11 corresponds to one installation groove 22. There are also multiple guide holes 12, which are the same as the number of guide posts 11. When the waterstop plate 2 slides up and down along the extension direction of the guide post 11, the sliding is more balanced and the waterstop plate 2 will not deviate.

[0034] Since multiple guide holes 12 are formed on the waterstop plate 2, in order to prevent the waterstop plate 2 from deforming, a reinforcing rib 13 is formed on the side of the waterstop plate 2 away from the water outlet panel 3. Specifically, the reinforcing rib 13 is arranged in a crisscross pattern.

[0035] In this specific embodiment, a ball joint 15 is hinged to the housing 1. A water inlet 16 is formed through the top wall of the ball joint 15. The water inlet 16 is connected to the water inlet channel 7. In use, the ball joint 15 is rotated to adjust the tilt angle of the housing 1. This is prior art and will not be described in detail.

[0036] Key points combined Figure 2 As shown, the water outlet panel 3 includes a decorative panel 17 and a water outlet component 18. The water outlet component 18 has a plurality of water outlet columns 19 arranged in an array. The water outlet 4 is passed through the water outlet column 19. The decorative panel 17 has mounting holes 20 that cooperate with the plurality of water outlet columns 19. The end of the water outlet column 19 facing the water stop plate 2 protrudes upward and abuts against the water stop plate 2. The end of the water outlet column 19 away from the water stop plate 2 passes through the mounting holes 20 and extends downward out of the bottom surface of the decorative panel 17.

[0037] Key points combined Figure 10 As shown, preferably, an elastic element 14 is provided between the waterstop plate 2 and the housing 1. The elastic element 14 is used to elastically drive the waterstop plate 2 to slide down, so that the waterstop plate 2 is close to the water outlet panel 3. In use, the water inlet channel 7 is connected to the external water source device. When the waterstop plate 2 slides up, it compresses the elastic element 14, opens the water outlet 4, and water flows out from the water outlet 4. When the external water source device is closed, the elastic element 14 elastically drives the waterstop plate 2 to move towards the water outlet panel 2. At the same time, combined with the gravity of the waterstop plate 2, it can quickly block the water outlet 4, realizing immediate shut-off.
