Description

Technical Field

[0001] This utility model relates to the field of bathroom product technology, and more specifically, to a roller-switchable shower head. Background Technology

[0002] Current showerheads typically switch water flow using three methods: rotating the faceplate assembly, pressing a button, or using a push-button. However, rotating the faceplate assembly is difficult to operate with one hand and inconvenient for users. Button and push-button switches usually involve a mechanism that drives a transmission to rotate the water distribution plate, thus switching the water flow. But both methods involve numerous transmission components located on the back of the water outlet assembly, resulting in a large and heavy showerhead that detracts from the showerhead's aesthetics. Furthermore, the transmission mechanisms are often linkages or levers, making smooth switching difficult to guarantee and resulting in a less than ideal feel. Utility Model Content

[0003] This utility model discloses a roller-type switchable shower head, which aims to improve the problem of the large head size of existing switchable shower heads.

[0004] The present invention adopts the following solution:

[0005] A roller-type switchable shower head includes a body and a switching assembly. The body has a water inlet channel, a water passage cavity, and at least two water outlet channels. The switching assembly is disposed on the handle of the body and includes a roller, a switching shaft, and a transmission structure for connecting the roller and the switching shaft. The roller is at least partially exposed on the handle. The switching shaft is not coaxial with the roller and is inserted into the water passage cavity. It has a water outlet communicating with the water inlet channel. By moving the roller along the length of the handle, the switching shaft is rotated in conjunction with the roller, thereby adjusting the position of the water outlet and selecting the water outlet channel communicating with the water outlet.

[0006] As a further improvement, when the water inlet is misaligned with each of the water outlet channels and aligned with the cavity wall of the water inlet chamber, the water inlet channel is isolated from each of the water outlet channels and is in a water-stopped state.

[0007] As a further improvement, the rotation axis of the roller is parallel to and vertically offset from the rotation axis of the switching shaft.

[0008] As a further improvement, the transmission structure includes a first gear coaxially arranged with the roller, a second gear coaxially arranged with the switching shaft, and a third gear meshing with both the first gear and the second gear, wherein the transmission between the first gear and the third gear, as well as between the second gear and the third gear, is a speed reduction transmission.

[0009] As a further improvement, the roller is integrally formed with the first gear, and the rotating shafts at both ends of the roller are inserted into the limiting grooves of the body, so that the roller and the body are rotatably connected.

[0010] As a further improvement, the second gear is provided with a positioning groove, and the body is provided with a positioning part. The positioning part cooperates with the positioning groove to limit the rotation angle of the switching shaft.

[0011] As a further improvement, the second gear is integrally formed with the switching shaft, and has at least a partially toothless area along the circumferential direction of the second gear, which forms the positioning groove.

[0012] As a further improvement, the main body includes a shell and an inlet pipe and an outlet assembly disposed within the shell. The inlet pipe is connected to the inlet end of the outlet assembly. The outlet assembly is provided with a first outlet channel, a second outlet channel, and a plurality of outlet nozzles communicating with the two outlet channels. The outlet nozzles are configured to cooperate with the first outlet channel to form a first type of water splash and cooperate with the second outlet channel to form a second type of water splash.

[0013] As a further improvement, the water outlet assembly includes a base plate, a water distribution component, a panel, and a top plate arranged sequentially from the inside to the outside on the main body. A first water outlet channel is formed between the base plate and the water distribution component, and a second water outlet channel is formed between the top plate and the water distribution component. The water outlet is disposed on the panel. Water in the first water outlet channel enters the water outlet longitudinally, and water in the second water outlet channel enters the water outlet laterally.

[0014] As a further improvement, the water distribution component is provided with a water inlet portion corresponding to each water outlet, an inclined water groove is provided along the circumference of the water inlet portion, and a water inlet hole is provided along the bottom of the water inlet portion. The first water outlet channel is connected to the water outlet through the water inlet hole, and the second water outlet channel is connected to the water outlet through the inclined water groove.

[0015] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0016] 1. This application integrates the switching component onto the handle, reducing the structural requirements of the shower head. It eliminates the need for a water distribution plate and switching mechanism, allowing for a thinner shower head with improved aesthetics and fewer design limitations. Furthermore, the off-axis configuration of the switching shaft and roller avoids the problem of an excessively large handle due to a coaxial configuration, which would negatively impact grip. Simultaneously, it simplifies the structure of the switching shaft and roller, facilitating the design and molding of the various water flow channels.

[0017] 2. By adjusting the overlapping area between the water inlet, the water outlet channel, and the cavity wall, the water flow rate can be adjusted and the water stop function can be achieved.

[0018] 3. The transmission structure adopts a reduction gear set, which can ensure stable transmission and smooth switching. The reduction setting can also improve the switching feel.

[0019] 4. The same spout can produce two different water sprays to ensure a wide water spray area for various spray patterns and enhance the showering experience. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model 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 this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example

[0033] Combination Figures 1 to 11 This embodiment provides a roller-type switchable shower head, including a body 1 and a switching assembly. The body 1 has a water inlet channel 11, a water passage chamber 12, and at least two water outlet channels. The switching assembly is disposed on the handle 13 of the body 1 and includes a roller 21, a switching shaft 22, and a transmission structure for connecting the roller 21 and the switching shaft 22. The roller 21 is at least partially exposed on the handle 13. The switching shaft 22 is not aligned with the roller 21 and is inserted into the water passage chamber 12. It has a water outlet 221 communicating with the water inlet channel 11. By moving the roller 21 along the length of the handle 13, the switching shaft 22 rotates, correspondingly adjusting the position of the water outlet 221, thereby selecting the water outlet channel connected to the water outlet 221. The user can manually move the roller 21 to drive the switching shaft 22 to rotate, thereby connecting the water outlet 221 with different water outlet channels to achieve the switching of water outlet channels. The roller 21 is ergonomically designed to be moved along the length of the handle 13, making it easy for users to operate.

[0034] It should be noted that in this embodiment, the switching component is configured on the handle 13, which reduces the structural requirements of the shower head. There is no need to include a water distribution plate or switching mechanism on the shower head, allowing for a thinner shower head, improved aesthetics, and fewer limitations on appearance design. Furthermore, the non-axial configuration of the switching shaft 22 and the roller 21 avoids the problem of an excessively large handle 13 due to a coaxial configuration of the roller 21 and switching shaft 22, which would affect the grip. Simultaneously, it simplifies the structure of the switching shaft 22 and the roller 21, facilitating the structural design and molding of each water outlet channel.

[0035] In a preferred embodiment, when the inlet 221 is misaligned with each outlet channel and aligned with the wall of the water passage 12, the inlet channel 11 is isolated from each outlet channel, entering a water-stopped state. This water-stopped state can be a small water flow state or a dripping state, to achieve water flow pause without needing to turn the faucet on or off, thereby preventing changes in water temperature. It is easy to understand that by adjusting the overlapping area between the inlet 221, the outlet channel, and the wall of the cavity, the water flow rate can be adjusted. That is, the switching shaft 22 of this embodiment can realize water-stopping, outlet channel switching, and flow rate adjustment functions, and its advantages are obvious compared with the prior art.

[0036] In another embodiment, the rotation axis of the roller 21 is parallel to and vertically offset from the rotation axis of the switching shaft 22. That is, the rotation direction of the switching shaft 22 is the same as that of the roller 21. The vertical offset arrangement makes the structure more compact. At the same time, the offset arrangement allows the water inlet channel 11 to flow under the roller 21. The offset position of the water passage cavity 12 and the roller 21 ensures the size of the water passage cavity 12, which is beneficial for water path switching.

[0037] Based on the above embodiments, in an optional embodiment of this utility model, the transmission structure includes a first gear 23 coaxially arranged with the roller 21, a second gear 24 coaxially arranged with the switching shaft 22, and a third gear 25 meshing with both the first gear 23 and the second gear 24. The transmission between the first gear 23 and the third gear 25, as well as between the second gear 24 and the third gear 25, is a reduction gear transmission. The gear transmission ensures stable transmission and smooth switching, while the reduction gear setting improves the switching feel.

[0038] Furthermore, the roller 21 and the first gear 23 are integrally formed, and the rotating shafts at both ends of the roller 21 are inserted into the limiting grooves 14 of the body 1, so that the roller 21 and the body 1 are rotatably connected. For example, the limiting groove 14 is a C-shaped groove, and the rotating shaft is inserted along the opening of the C-shaped groove and restricted from sliding out by the limiting block 15. The integral forming of the roller 21 and the first gear 23 can reduce the number of parts and assembly.

[0039] Preferably, the second gear 24 is provided with a positioning groove 241, and the body 1 is provided with a positioning part 16. The positioning part 16 cooperates with the positioning groove 241 to limit the rotation angle of the switching shaft 22 so as to ensure accurate switching position. Preferably, the second gear 24 and the switching shaft 22 are integrally formed, and the second gear 24 has at least a partially toothless area along the circumference of the second gear 24. This area forms the positioning groove 241 to further reduce the number of parts and simplify the structure, thereby saving costs.

[0040] Based on the above embodiments, in an optional embodiment of this utility model, the main body 1 includes a shell 17 and a water inlet pipe 18 and a water outlet assembly disposed within the shell 17. The water inlet pipe 18 is connected to the water inlet end of the water outlet assembly. The water outlet assembly is provided with a first water outlet channel 19, a second water outlet channel A1, and a plurality of water outlets A41 communicating with the two water outlet channels. The water outlets A41 are configured to cooperate with the first water outlet channel 19 to form a first type of water spray, and cooperate with the second water outlet channel A1 to form a second type of water spray. That is, in this embodiment, the same water outlet A41 can spray two different types of water spray to ensure the water spray area of ​​various water sprays and improve the shower experience.

[0041] For example, the water outlet assembly includes a base plate A2, a water distributor A3, a panel A4, and a top plate A5, arranged sequentially from the inside to the outside on the main body 1. A first water outlet channel 19 is formed between the base plate A2 and the water distributor A3, and a second water outlet channel A1 is formed between the top plate A5 and the water distributor A3. A water outlet A41 is disposed on the panel A4. Water in the first water outlet channel 19 enters the water outlet A41 longitudinally, and water in the second water outlet channel A1 enters the water outlet A41 transversely. The base plate A2, the water distributor A3, the panel A4, and the top plate A5 can all be fixed by welding.

[0042] In one embodiment, the water distribution component A3 is provided with a water inlet corresponding to each water outlet A41. An inclined water groove A31 is provided along the circumferential direction of the water inlet, and a water inlet hole A32 is provided along the bottom of the water inlet. The first water outlet channel 19 is connected to the water outlet A41 through the water inlet hole A32, and the second water outlet channel A1 is connected to the water outlet A41 through the inclined water groove A31. When the first water outlet channel 19 is connected to the water inlet channel 11, the water flows from the first water outlet channel 19 to the water inlet hole A32, and then sprays directly from the water outlet A41, forming the first type of water splash; when the second water outlet channel A1 is connected to the water inlet channel 11, the water flows from the second water outlet channel A1 to the inclined water trough A31. The inclined water trough A31 can be set along the tangential direction of the water inlet so that the water flows through the inclined water trough A31 and accelerates before being sprayed from the water outlet A41, forming a second type of water splash that is different from the first type of water splash.

[0043] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are within the protection scope of this utility model.
