Description

Technical Field

[0001] This invention relates to the field of bathroom product technology, and more specifically, to a water outlet structure with different water sprays from the same spout and a shower faucet. Background Technology

[0002] Traditional multi-functional showerheads use multiple different nozzles to create various water spray patterns. However, due to the limited area of ​​the showerhead, the area that each nozzle can cover is small, resulting in a small spray area for each water spray pattern and affecting the water output effect. To address this, water spray structures with different spray patterns from the same nozzle have been introduced to ensure that the water spray area is the same for each pattern. However, most existing water spray structures with different spray patterns from the same nozzle are similar to those disclosed in Chinese CN108499759B, which describes a shower faucet that switches between different spray patterns from the same outlet, or CN114160323A, which describes a water spray structure with different spray patterns from the same nozzle and a shower faucet using this structure. The former uses a drive component to move a water flow reversing component, changing the direction of the water flow into the outlet to create different spray patterns. The latter has slots with different directions at the inlet end of the nozzle, each slot connecting to a different chamber. A water distribution component selects the chamber through which water flows, allowing water to enter the nozzle from the corresponding slot, creating different spray patterns. In the above water outlet structures with different water splashes but the same spout, different water splashes are formed by changing the direction of the water flow entering the spout. However, the direction of the water flow entering the spout is limited, generally either straight or oblique. Therefore, the water splashes that can be formed are very similar, which can easily lead to aesthetic fatigue and is not conducive to market promotion. Summary of the Invention

[0003] This invention discloses a water outlet structure with different water splashes from the same nozzle, aiming to improve the problem of similar water splashes formed by various existing water outlet structures with different water splashes from the same nozzle, which easily leads to aesthetic fatigue.

[0004] The present invention adopts the following solution: A water outlet structure with different water splashes from the same spout includes an inlet seat, an outlet cover, and an inner outlet plate. The outlet cover has multiple first water outlet holes, and the inlet seat and the outlet cover enclose a water passage cavity. The inner outlet plate is disposed in the water passage cavity and has water outlet parts corresponding to each of the first water outlet holes. Each water outlet part has a second water outlet hole with a different shape and / or size than the first water outlet hole. The inner outlet plate is configured to move towards or away from the first water outlet hole, so that the water outlet parts extend into or away from the first water outlet hole, and the corresponding water flows out from the second water outlet hole or the first water outlet hole, thereby forming different water splashes.

[0005] As a further improvement, the first water outlet is located at the bottom of the water outlet cover, and the inner water outlet plate has a limiting surface. When the water outlet part extends into the first water outlet, the limiting surface abuts and seals against the inner bottom surface of the water outlet cover.

[0006] As a further improvement, the inner water outlet plate is mounted or formed on the driving component, and the inner water outlet plate is moved by rotating or pressing the water outlet cover in conjunction with the driving component.

[0007] As a further improvement, the water outlet cover is provided with a locking part and a positioning part. The locking part engages with the sliding groove of the water inlet seat and can move along the sliding groove. The positioning part is inserted into the assembly hole of the drive component to drive the drive component to rotate.

[0008] As a further improvement, the end of the drive member away from the water inlet seat is provided with an elastic member, the water inlet seat is provided with a first helical tooth, and the drive member has a second helical tooth for abutting against the helical tooth. While the drive member rotates with the water outlet cover, the second helical tooth slides along the tooth surface of the first helical tooth under the action of the elastic member, so that the drive member can move axially.

[0009] As a further improvement, the tooth surface of the first helical tooth and the tooth surface of the second helical tooth are conformally arranged. The tooth surface of the first helical tooth includes an inclined surface and a high abutment surface and a low abutment surface located at both ends of the inclined surface. When the second helical tooth slides along the inclined surface to abut against the high abutment surface, the water outlet part moves away from the first water outlet hole. When the second helical tooth slides along the inclined surface to abut against the low abutment surface, the water outlet part extends into the first water outlet hole.

[0010] As a further improvement, the bottom surface of the drive member is provided with a first water passage groove, and the side surface is provided with a second water passage groove. When the water outlet is away from the first water outlet, the water flows from the first water passage groove to the first water outlet. When the water outlet extends into the first water outlet, the bottom surface of the drive member abuts against the inner bottom surface of the water outlet cover, so that the water flows from the second water passage groove to the second water outlet.

[0011] As a further improvement, a guide sleeve rotatably connected to the water inlet seat is disposed inside the water passage cavity. The guide sleeve is sleeved on the outside of the drive member and has a guide portion extending into the second water passage groove.

[0012] As a further improvement, the outer wall of the water outlet is configured to resemble the inner wall of the first water outlet hole.

[0013] Another shower faucet is provided, including a water outlet body and a water outlet structure with different water sprays from the same spout as described in any of the preceding claims, disposed on the water outlet body.

[0014] By adopting the above technical solution, the present invention can achieve the following technical effects: 1. This application achieves two different water spray patterns from the same nozzle by setting a movable inner water outlet plate within the water passage cavity and setting a second water outlet hole on the water outlet plate with a different shape and / or size than the first water outlet hole. The different water spray patterns are generated by changes in the diameter and / or shape of the water outlet hole, enabling variations in water shape and pressure. This provides a new approach to water outlet structure design, increases the diversity of water outlet structures, meets the aesthetic needs of different users, and thus enhances market competitiveness. Compared with existing technologies that can only change the water inlet direction to create different water spray patterns, its advantages are obvious.

[0015] 2. The structure is simple and has few parts, which makes the overall volume of the water outlet structure small, which is beneficial for its application in different shower faucets. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

The terms “first,” “second,” etc., are only used to distinguish different objects and should not be construed as indicating or implying relative importance or the quantity, specific order, or primary or secondary relationship of the indicated technical features. The term “several” means one or more, and “multiple” means two or more, unless otherwise explicitly specified. Example

[0021] Combination Figures 1 to 14This embodiment provides a water outlet structure with different water splashes from the same spout, including a water inlet seat 1, a water outlet cover 2, and an inner water outlet plate 3. The water outlet cover 2 is provided with multiple first water outlet holes 21, and the water inlet seat 1 and the water outlet cover 2 enclose a water passage cavity. The inner water outlet plate 3 is disposed in the water passage cavity and is provided with water outlet parts 31 corresponding to each of the first water outlet holes 21. Each water outlet part 31 is provided with a second water outlet hole 311 with a different shape and / or size than the first water outlet hole 21. The inner water outlet plate 3 is configured to move towards or away from the first water outlet hole 21, so that the water outlet part 31 extends into or away from the first water outlet hole 21, and the corresponding water flow flows out from the second water outlet hole 311 or the first water outlet hole 21, thereby forming different water splashes.

[0022] For example, the water inlet seat 1 is provided with a water inlet channel 11 communicating with the water passage cavity. When the water outlet 31 is away from the first water outlet 21, water flows into the water inlet seat 1 and then flows through the water passage cavity to the first water outlet 21, forming a first type of water splash. When the water outlet 31 extends into the first water outlet 21, water flows into the water inlet seat 1 and then flows through the water passage cavity to the second water outlet 311, forming a second type of water splash. Preferably, the second water outlet 311 and the first water outlet 21 are concentrically arranged. The diameter of the second water outlet 311 is smaller. The first type of water splash is a water jet with a larger diameter, and the second type of water splash is a pressurized water jet with a smaller diameter, so that a certain rinsing force can still be obtained when the water pressure is low, ensuring the cleaning effect.

[0023] It should be noted that in this embodiment, by setting a movable inner water outlet plate 3 within the water passage cavity, and setting a second water outlet hole 311 on the water outlet plate with a different shape and / or size than the first water outlet hole 21, two different water sprays can be achieved from the same water outlet. The different water sprays are generated by changes in the diameter and / or shape of the water outlet hole, enabling changes in water shape and pressure. This provides new ideas for the design of water outlet structures, increases the diversity of water outlet structures, meets the aesthetic needs of different users, and thus enhances market competitiveness. Compared with existing technologies, which can only change the water inlet direction to create different water sprays, its advantages are obvious.

[0024] In a preferred embodiment, the first water outlet 21 is located at the bottom of the water outlet cover 2, and the inner water outlet plate 3 has a limiting surface 32. When the water outlet part 31 extends into the first water outlet 21, the limiting surface 32 abuts and seals against the inner bottom surface of the water outlet cover 2. The limiting surface 32 prevents water from overflowing between the outer wall of the water outlet part 31 and the inner wall of the first water outlet 21 when water is discharged from the second water outlet 311. It also acts as a limiting force when the water outlet part 31 extends into the first water outlet 21, ensuring that the lengths of each water outlet part 31 extending into the first water outlet 21 are the same. Furthermore, the outer wall of the water outlet part 31 is similar in shape to the inner wall of the first water outlet 21, and can be conical, to facilitate the entry and exit of the water outlet part 31 from the first water outlet 21.

[0025] Preferably, the inner water outlet plate 3 is mounted or formed on the driving component 4, and the inner water outlet plate 3 is moved by rotating or pressing the water outlet cover 2 in conjunction with the driving component 4. The inner water outlet plate 3 can be made of soft rubber, arranged around the periphery of the driving component 4, and formed with the driving component 4 through secondary overmolding. Alternatively, it can be made of hard rubber, integrally injection molded with the driving component 4, or fixed to the driving component 4 by welding or other methods.

[0026] In one embodiment, the structure for linking the drive element 4 and the water outlet cap 2 is a press-type structure of a ballpoint pen. Pressing the water outlet cap 2 switches the drive element 4 between a first position and a second position. The press-type structure of a ballpoint pen is existing technology and will not be described in detail here. In another embodiment, the water outlet cover 2 is provided with a locking part 22 and a positioning part 23. The locking part 22 engages with the sliding groove 12 of the water inlet seat 1 and can move along the sliding groove 12. The positioning part 23 is inserted into the assembly hole 41 of the driving member 4 to drive the driving member 4 to rotate. For example, the sliding groove 12 is provided along the side wall of the water inlet seat 1. When the water outlet cover 2 is rotated, the locking part 22 moves along the sliding groove 12, and at the same time, the positioning part 23 drives the driving member 4 to rotate synchronously. The locking part 22 can be a snap-fit. The locking part 22 engages with the sliding groove 12, which can limit the water outlet cover 2 axially, and the length of the sliding groove 12 can limit the rotation angle of the water outlet cover 2. The positioning part 23 is provided on the inner bottom surface of the water outlet cover 2 and is columnar. The assembly hole 41 is provided on the bottom surface of the driving member 4, and the height of the positioning part 23 is not less than the distance that the driving member 4 moves axially.

[0027] For example, the end of the drive member 4 away from the water inlet seat 1 is abutted against an elastic member 5. The water inlet seat 1 is provided with a first helical tooth 13, and the drive member 4 has a second helical tooth 42 for abutting against the helical tooth. As the drive member 4 rotates with the water outlet cover 2, the second helical tooth 42 slides along the tooth surface of the first helical tooth 13 under the action of the elastic member 5, so that the drive member 4 can move axially. The elastic member 5 can be a spring. The bottom surface of the water outlet cover 2 is provided with a mounting shaft 24, and the spring is sleeved on the mounting shaft 24 and abuts against the drive member 4. Under the action of the spring force, the second helical tooth 42 on the drive member 4 can maintain abutting against the first helical tooth 13. When the second helical tooth 42 slides along the tooth surface of the first helical tooth 13, the drive member 4 can drive the inner water outlet plate 3 to move towards or away from the water outlet cover 2.

[0028] Specifically, the tooth surfaces of the first helical tooth 13 and the second helical tooth 42 are conformally arranged. The tooth surface of the first helical tooth 13 includes an inclined surface 131 and a high abutment surface 132 and a low abutment surface 133 located at both ends of the inclined surface 131. When the second helical tooth 42 slides along the inclined surface 131 to abut against the high abutment surface 132, the water outlet 31 moves away from the first water outlet hole 21. When the second helical tooth 42 slides along the inclined surface 131 to abut against the low abutment surface 133, the water outlet 31 extends into the first water outlet hole 21. Multiple first helical teeth 13 are formed on the water inlet seat 1, and multiple second helical teeth 42 are correspondingly formed on the drive member 4. The drive member 4 moves axially while rotating through the helical teeth for guidance and positioning. The structure is simple and has few parts.

[0029] Based on the above embodiments, in an optional embodiment of the present invention, the bottom surface of the driving member 4 is provided with a first water passage groove 43, and the side surface is provided with a second water passage groove 44. When the water outlet 31 is away from the first water outlet 21, the water flows from the first water passage groove 43 to the first water outlet 21. When the water outlet 31 extends into the first water outlet 21, the bottom surface of the driving member 4 abuts against the inner bottom surface of the water outlet cover 2, so that the water flows from the second water passage groove 44 to the second water outlet 311. The driving member 4 is integrally formed, which can both drive the inner water outlet plate 3 to move and realize the switching of the water flow channel, simplifying the structure and reducing the volume of the water outlet structure, so that the water outlet structure can be used in different shower faucets. It should be noted that when the water outlet 31 is away from the first water outlet 21, even if the water flows from the second water passage groove 44 into the second water outlet 311, it does not affect the water outlet of the first water outlet 21.

[0030] Preferably, a guide sleeve 6 rotatably connected to the water inlet seat 1 is disposed within the water passage cavity. The guide sleeve 6 is fitted onto the outer side of the drive member 4 and has a guide portion 61 extending into the second water passage groove 44. The guide sleeve 6 ensures the direction of movement of the drive member 4, preventing the drive member 4 from deflecting during movement and causing switching jamming. The guide portion 61 is inserted into the guide groove, which reduces the number of slots on the drive member 4 and avoids weakening the strength of the drive member 4. In other embodiments, a boss 62 is provided along the periphery of the guide sleeve 6. The boss 62 can be hung on the top of the water outlet cover 2, and a sealing ring 7 is provided between the boss 62 and the top surface of the water outlet cover 2. The sealing ring 7 seals against the inner wall of the water inlet seat 1 to prevent water from overflowing from the water passage cavity.

[0031] The present invention also provides a shower faucet, including a water outlet body and a water outlet structure as described in any of the above embodiments, disposed on the water outlet body, which allows for different water sprays from the same spout. The shower faucet can be a shower head or overhead shower, etc. Exemplarily, the water outlet structure can be located in the middle of the water outlet body to form different water sprays from the same spout in the middle of the water outlet body. Alternatively, it can be located at the water outlet end of the entire water outlet body so that different water sprays from the same spout can be formed on the entire water outlet surface of the water outlet body; however, it is not limited thereto and is not specifically limited thereto.

[0032] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions that fall within the scope of the present invention are within the scope of protection of the present invention.
