Description

Technical fields:

[0001] This utility model belongs to the technical field of bathroom products, and specifically refers to a shower head. Background technology:

[0002] Chinese utility model patent (publication number CN221789693U, application date 2024.01.18, publication date 2024.10.01) discloses an LED shower head, including: a semi-transparent bottom cover; a top spray protective cover, the lower part of which is fastened to the top of the shower head, the surface of which is provided with an annular upward-protruding LED lampshade; a silicone water outlet plate, placed between the top spray protective cover and the semi-transparent bottom cover, the surface of which has a ring-shaped array of several small water outlet holes and an innermost ring of annularly distributed water outlet columns. The lower end of the silicone water outlet plate is fixed with a downward-protruding water outlet strip, and the small water outlet holes penetrate the water outlet strip and the silicone water outlet plate respectively. The surface of the semi-transparent bottom cover has a filling hole and an innermost ring of fixed water outlet columns, the groove shape of which matches the protruding shape of the water outlet strip. The downward-protruding water outlet column at the bottom of the silicone water outlet plate corresponds to and is connected to the water outlet column of the inner ring of the semi-transparent bottom cover. The center of the semi-transparent top cover is provided with an inner cover cylinder, and the opening of the inner cover cylinder protrudes downward from the semi-transparent top cover. The top of the inner cover cylinder is connected to an inner connecting pipe, and the top of the semi-transparent top cover, which is outside the inner cover cylinder, is connected to an outer connecting pipe. Water flowing from the inner connecting pipe can enter the cavity of the inner casing. The opening of the inner casing is close to the outer ring of the water outlet column. The bottom opening of the inner casing isolates the small water outlet hole and the water flow channel of the water outlet column. This allows the water flowing from the inner connecting pipe into the inner casing to spray out along the water outlet column, while the water flowing from the outer connecting pipe can spray downwards along the small water outlet hole. The top of the top spray protective cover is equipped with a sleeve that fits the inner and outer connecting pipes. The sleeve covers the inner and outer connecting pipes and is assembled with the top spray protective cover using studs on the annular outer wall of the semi-transparent bottom cover. The LED lamps inside the cover project a ring beam of light, which passes through the silicone water outlet plate. This reflects the direction of water flow and the downward spray, thus enhancing the visual experience of showering. Moreover, placing the LED lamp cover at the top of the shower head reduces the direct impact of splashing water and water vapor on the LED lamp column.

[0003] The shortcomings of the aforementioned LED shower head are that after prolonged use, the silicone water outlet plate is prone to bulging, causing the water flow channels of the small water outlet holes and the inner water column to connect, resulting in water leakage. Consequently, the two different spray patterns, the small water outlet holes and the water column, will spray water simultaneously, making it impossible to control them separately. Summary of the Invention:

[0004] The purpose of this invention is to provide a shower head that can effectively prevent water from flowing out of the shower head, so that the inner water outlet and the outer water outlet will not flow out water at the same time, thereby achieving individual control.

[0035] The present invention will be further described below with reference to specific embodiments. See also: Figure 1 —8:

[0036] A shower head includes a bottom cover 1, an annular top cover 2 and an inner cover 3 sealed together on the bottom cover 1. The inner cover 3 is located in the middle of the annular top cover 2. The annular top cover 2 is provided with an external connecting pipe 4, and the inner cover 3 is provided with an internal connecting pipe 5. An outer chamber 6 is formed between the annular top cover 2 and the bottom cover 1, communicating with the external connecting pipe 4. An inner chamber 7 is formed between the inner cover 3 and the bottom cover 1, communicating with the internal connecting pipe 5. A silicone water outlet plate 10 located in the outer chamber 6 is attached to the side of the bottom cover 1 near the annular top cover 2. An installation groove 11 is provided on the bottom cover 1. A water outlet strip 12 extending out of the installation groove 11 is provided on the silicone water outlet plate 10 and the water outlet strip 12. An outgoing water hole 8 communicating with the outer chamber 6 is provided through the silicone water outlet plate 10 and the water outlet strip 12. An inner water outlet hole 9 communicating with the inner chamber 7 is provided on the bottom cover 1.

[0037] Furthermore, the water outlet 8 and the inner water outlet 9 produce different water output effects, forming two water spraying modes.

[0038] The working principle of this utility model is as follows: Figure 1-8 As shown, the water flowing into the inner chamber 7 from the inner connecting pipe 5 flows out through the inner water outlet 9, and the water flowing into the outer chamber 6 from the outer connecting pipe 4 flows out through the outer water outlet 8, forming two different spray patterns at the inner water outlet 9 and the outer water outlet 8. The two different spray patterns can be controlled independently, making it convenient to adjust the shower.

[0039] like Figure 1-8 As shown, this utility model is provided with an annular upper cover 2 and an inner cover 3 that are respectively sealed and connected to the bottom cover 1. An outer chamber 6 is formed between the annular upper cover 2 and the bottom cover 1, which is connected to the outer connecting pipe 4. An inner chamber 7 is formed between the inner cover 3 and the bottom cover 1, which is connected to the inner connecting pipe 5. The outer chamber 6 and the inner chamber 7 formed by the annular upper cover 2 and the inner cover 3 effectively isolate the water flow channels of the inner water outlet 9 and the outer water outlet 8, thereby effectively preventing water leakage. At the same time, the silicone water outlet plate 10 of this utility model is set inside the outer chamber 6, instead of the traditional connection between the outer chamber 6 and the inner chamber 7, which effectively avoids water leakage due to silicone bulging. This ensures that the inner water outlet 9 and the outer water outlet 8 do not emit water at the same time, thus enabling individual control.

[0040] Furthermore, the inner water outlet 9 is located in the middle of the bottom cover 1, and the inner water outlet 9 is distributed in a circular pattern, while the outer water outlet 8 is located on the outside of the inner outlet hole 9.

[0041] Preferably, the water outlet strip 12 is arc-shaped, and multiple strips are evenly distributed around the circumference to form a group of annular water outlet components. The annular water outlet components are arranged radially with multiple channels, and each water outlet strip 12 is provided with two or more water outlet holes 8.

[0043] The sealing connection structure between the inner cover 3 and the bottom cover 1 is as follows: Figure 3 , 7 As shown in Figure 8, the inner cover 3 includes an inner cover plate 3a and an inner cover sidewall 3b connected at one end to the outer periphery of the inner cover plate 3a. The other end of the inner cover sidewall 3b is sealed to the bottom cover 1. The inner cover plate 3a, the inner cover sidewall 3b, and the bottom cover 1 form the inner cavity 7. The structure is simple and easy to process and install.

[0044] The sealing connection structure between the annular upper cover 2 and the bottom cover 1 is as follows: Figure 3-5 As shown in Figures 7 and 8, the annular upper cover 2 includes an annular upper cover plate 2a, an inner wall 2b connected at one end to the inner ring of the annular upper cover plate 2a, and an outer wall 2c connected at one end to the outer ring of the annular upper cover plate 2a. The bottom cover 1 has an annular inner mounting part 13 and an annular outer mounting part 14 protruding to one side of the annular upper cover 2. The other end of the inner wall 2b of the upper cover is sealed to the annular inner mounting part 13, and the other end of the outer wall 2c of the upper cover is sealed to the annular outer mounting part 14. The annular upper cover plate 2a, the inner wall 2b of the upper cover, the outer wall 2c of the upper cover, the annular inner mounting part 13, the annular outer mounting part 14, and the bottom cover 1 form the outer cavity 6. An annular groove 15 for installing the silicone water outlet plate 10 is formed between the annular inner mounting part 13 and the annular outer mounting part 14. The inner cover side wall 3b is disposed inside the annular inner mounting part 13. The structure is simple and easy to process and install.

[0045] To achieve a better sealing effect, the surface of the annular inner mounting part 13 protrudes from the surface of the silicone water outlet plate 10. The end of the inner wall 2b of the upper cover connected to the annular inner mounting part 13 is provided with a notch 16 that matches the annular inner mounting part 13 and forms an L-shape. The outer end face 17 of the end of the inner wall 2b of the upper cover connected to the annular inner mounting part 13 abuts against the silicone water outlet plate 10, and the inner end face 18 is sealed to the annular inner mounting part 13. The annular upper cover plate 2a protrudes to the side of the bottom cover 1 with an annular abutment part 19. The end of the annular abutment part 19 away from the annular upper cover plate 2a abuts against the silicone water outlet plate 10. The water outlet hole 8 is located inside the annular abutment part 19. The annular outer mounting part 14 is provided with a mounting groove 20. The end of the outer wall 2c of the upper cover away from the annular upper cover plate 2a is sealed to the mounting groove 20.

[0046] In order to locate the installation position of the silicone water outlet plate 10, such as Figure 3-5 As shown in Figures 7 and 8, the bottom cover 1 has multiple positioning posts 21 protruding towards the annular top cover 2. The silicone water outlet plate 10 is provided with positioning holes 22 that are adapted to the positioning posts 21. The annular top cover plate 2a has a connecting post 23 protruding towards the bottom cover 1. The end of the connecting post 23 away from the annular top cover plate 2a is sealed to the positioning post 21, making the connection between the annular top cover 2 and the bottom cover 1 more secure.

[0047] Positioning structure of the annular upper cover 2 and the bottom cover 1: as follows Figure 7 As shown, the outer periphery of the outer wall 2c of the upper cover is provided with a limiting protrusion 31, and the annular outer mounting part 14 is provided with a limiting groove 32 that matches the limiting protrusion 31.

[0048] In order to make the water from the inner water outlet 9 appear as an atomized state, such as Figure 3 , 4As shown in Figures 6-8, an atomizer 24 is provided inside the inner water outlet 9. The atomizer 24 includes a large cylinder 24a and a small cylinder 24b. A water passage groove 25 is provided on the outer periphery of the large cylinder 24a. The large cylinder 24a is disposed inside the inner water outlet 9 and a gap is left between it and the hole wall of the inner water outlet 9. The small cylinder 24b extends into the inner cavity 7. A limiting post 26 is provided on the inner cover plate 3a to restrict the large cylinder 24a from completely leaving the inner water outlet 9.

[0049] In order to position the inner cover 3 and the bottom cover 1 for installation, such as Figure 7 , 8 As shown, the bottom cover 1 is provided with a positioning quadrilateral 33, the inner cover plate 3a is provided with a mounting post 34, and the mounting post 34 is provided with a positioning quadrilateral hole 35 that is adapted to the positioning quadrilateral 33.

[0050] To prevent the limiting post 26 from contacting the small cylindrical hole 9c during ultrasonic welding of the inner cover 3 and the bottom cover 1, which would cause the side wall of the large cylindrical body 24a to rub against the wall of the large cylindrical hole 9a and weld together, the inner water outlet 9 includes a large cylindrical hole 9a, a conical hole 9b, and a small cylindrical hole 9c connected in sequence. The large cylindrical hole 9a is located on the side of the conical hole 9b closer to the inner cavity 7. The large cylindrical body 24a is disposed inside the large cylindrical hole 9a. When the large cylindrical body 24a abuts against the conical hole 9b, a gap is left between the limiting post 26 and the small cylindrical hole 9c, so that the large cylindrical body 24a will not connect with the large cylindrical hole 9a due to ultrasonic waves, thereby ensuring the atomization effect and a good atomization effect.

[0051] Furthermore, the bottom cover 1 has mounting protrusions 36 protruding from the side away from the annular top cover 2. The number and position of the mounting protrusions 36 are adapted to the inner water outlet 9, and the inner water outlet 9 is set through the mounting protrusions 36.

[0052] Furthermore, the annular upper cover 2 has multiple limiting plates 27 protruding from the side away from the bottom cover 1, forming a light groove 28 for installing LED lights between the limiting plates 27. The annular upper cover 2 and the bottom cover 1 are made of light-transmitting material. During showering, the light emitted by the LED lights passes through the annular upper cover 2, the silicone water outlet plate 10, and the bottom cover 1 and is projected downwards. The projected light is soft and can reflect the flow trajectory of water in the shower head downwards, greatly improving the showering experience compared to traditional shower heads.

[0053] The LED light of this utility model is installed on the annular upper cover 2. During installation, simply fasten the protective cover 29, which facilitates the installation of the protective cover 29.

[0054] Furthermore, the limiting plate 27 is annular, and the lamp groove 28 is ring-shaped.

[0055] Preferably, the light-transmitting material is a transparent material or a translucent material. In this embodiment, the light-transmitting material is a translucent material.

[0056] To protect the LED lights, the annular upper cover 2 is covered with a protective cover 29. The outer connecting pipe 4 is located on the side of the annular upper cover 2 away from the bottom cover 1, and the inner connecting pipe 5 is located on the side of the inner cover 3 away from the bottom cover 1. The protective cover 29 is provided with a clearance slot 30 to avoid the outer connecting pipe 4 and the inner connecting pipe 5.

[0057] Furthermore, the bottom cover 1, the annular top cover 2, and the inner cover 3 are all made of plastic, and the annular top cover 2 and the inner cover 3 are respectively sealed to the bottom cover 1 by ultrasonic welding.

[0058] To reduce assembly steps and ensure a secure connection, the bottom cover 1, the inner annular mounting part 13, the outer annular mounting part 14, and the positioning post 21 are integrated into one structure; the upper annular cover 2, the annular abutment part 19, the connecting post 23, and the limiting plate 27 are integrated into one structure; and the inner cover 3 and the limiting post 26 are integrated into one structure.

[0059] The installation process of the shower head components of this utility model is as follows: First, install the silicone water outlet plate 10 in the annular groove 15. Then, put the atomizer 24 into the large cylindrical hole 9a. Next, weld the inner cover 3 to the bottom cover 1 by ultrasonic welding. Then, weld the annular upper cover 2 to the bottom cover 1 by ultrasonic welding. Next, place the LED light in the light groove 28. Finally, cover with the protective cover 29.

[0060] The installation process of this utility model of shower head and shower screen is as follows: Place the shower head inside the shower screen, with the bottom cover 1 tightly attached to the front panel of the shower screen. The water outlet strip 12 and the mounting protrusion 36 extend out of the through groove of the front panel of the shower screen. Then, the shank of the bolt passes through the connecting plate located on the rear side of the shower head and is screwed into the nut. The shank of the bolt abuts against the protective cover 29, thus limiting the shower head of this utility model between the front panel and the shank of the bolt to fix the shower head of this utility model.

[0061] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
