Description

Technical Field

[0001] This invention relates to the field of bathroom equipment technology, and in particular to an adjustment mechanism for a shower. Background Technology

[0002] As a common device in modern bathroom life, showers are mainly used to provide water flow for human body cleaning and relaxation. With the development of technology, showers have evolved from a single fixed nozzle to a system with multiple water output modes and adjustment functions, such as handheld showers, overhead showers and side showers, aiming to meet users' needs for bathing comfort, water conservation and personalization.

[0003] During a shower, users often have different preferences and needs regarding the spray range and water pressure. For example, a large area of ​​gentle water flow may be needed for a quick rinse, while a smaller area of ​​high-pressure water flow may be preferred for deep cleaning or massage. Therefore, the shower's adjustment function is crucial to improving the bathing experience, as it directly relates to the uniformity of water flow distribution, the adaptability of impact force, and overall water efficiency.

[0004] Most showerheads on the market use independent control of the spray range and water pressure. This means that users need to adjust the opening and closing of the nozzles or switch gears to change the coverage area. At the same time, the water pressure is controlled separately through valves or water pressure regulating devices, which affects the balance and comfort of the water flow during the shower. Summary of the Invention

[0005] In view of the problem that the spray range and water flow pressure cannot be synchronized and coordinated in the above or existing technologies, the present invention is proposed.

[0006] Therefore, the object of the present invention is to provide an adjustment mechanism for a shower.

[0014] The rotation of the rotating block causes the moving block to move back and forth, providing driving force for the radial movement of the throttling disc. By moving multiple throttling discs, the spray range of the water outlet and the position of the rotating disc are adjusted, so that the spray range and water pressure are adaptively adjusted to ensure the comfort of people when bathing.

[0015] In a preferred embodiment of the adjustment mechanism of a shower device according to the present invention, the shower assembly further includes a mounting console, which is disposed on the outer wall of the positioning frame, a top spray head is disposed at the end of the positioning frame, and a water pipe is disposed on the end face of the positioning frame.

[0020] As a preferred embodiment of the adjustment mechanism of a shower device according to the present invention, the second adjustment component further includes a sliding groove formed on the outer wall of the positioning plate near the extension member, and the outer wall of the rotating plate is provided with an inclined groove.

[0021] In a preferred embodiment of the adjustment mechanism of a shower device according to the present invention, the sliding groove and the inclined groove are positioned correspondingly, the sliding block can slide along the sliding groove, and the second guide block can slide along the inclined groove.

[0022] The beneficial effects of the shower adjustment mechanism of the present invention are as follows: The present invention operates by manually controlling the drive component, and uses the rotating block and the moving block to convert the rotational force of the screw block into the radial movement force of the throttling disc. The movement of the throttling disc is used to adjust the spray range of the positioning disc.

[0037] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0039] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments. Example 1

[0040] Reference Figures 1 to 10 This is the first embodiment of the present invention, which provides an adjustment mechanism for a shower that enables rapid adjustment of the shower and spray range for a person.

[0041] Specifically, a shower adjustment mechanism includes a shower assembly 1, which includes a positioning frame 12 and a handheld shower head 16 disposed on the outside of the positioning frame 12; wherein, the positioning frame 12 is fixedly installed to ensure the stable installation of each component of the shower assembly 1, while the movable and removable handheld shower head 16 ensures the convenience of showering, and provides an installation environment for the first adjustment component 2 and the second adjustment component 3.

[0042] And the first adjustment component 2 includes a drive member 21 and an extension member 22 disposed outside the drive member 21; wherein the drive member 21 provides power input to the extension member 22 and the second adjustment component 3 synchronously.

[0043] The driving component 21 includes a rotating block 212 disposed inside the handheld shower head 16, a first guide groove 213 formed on the end face of the rotating block 212, a limiting groove 219 formed on the end face of the first guide groove 213, and a moving block 218 disposed on the outer wall of the rotating block 212. The connection between the rotating block 212 and the handheld shower head 16 requires a sealing O-ring or a waterproof sealant to prevent water from leaking out through the gap between them. The first guide groove 213 includes straight grooves at both ends and arc grooves at both ends. The two straight grooves and two arc grooves are designed along the outer surface of the rotating block 212 and are symmetrically distributed. The arc groove is designed with an inclination, and its two ends are connected to the beginning and end of the straight groove at different positions, thus forming a continuous loop guide groove. The moving block 218 is disc-shaped and can move within the handheld shower head 16. The limiting groove 219 is a set of equidistantly distributed groups, which can limit the first guide block 214. It should be noted that when the first guide block 214 is inserted into the limiting groove 219, if the person does not rotate it, the elastic force of the first spring 216 alone cannot reset the drive rod 217, thereby locking the first guide block 214 and ensuring the stability of the structure after the spray range is adjusted.

[0044] Furthermore, the extension member 22 includes an outer plate 221 fixedly connected to the outer wall of the moving block 218, a throttling plate 226 disposed on the outer side of the outer plate 221, and a sliding block 227 fixedly connected to the outer wall of the throttling plate 226; wherein, the outer plate 221 is fixedly connected to the moving block 218, and the throttling plate 226 is designed in multiple groups. When the spray range is at its minimum, multiple throttling plates 226 together form a complete ring. Since each column of the outer wall of the positioning plate 31 and the rotating plate 34 in this application has three groups of water outlet holes 33, the end face of the throttling plate 226 in this application needs to be able to block up to two groups of water outlet holes 33. Accordingly, the end face of the throttling plate 226 is adjusted and designed according to the number and distribution of the water outlet holes 33 of the positioning plate 31.

[0045] The second adjustment component 3 includes a positioning plate 31 fixedly connected to the inner wall of the handheld shower head 16, a rotating plate 34 rotatably connected to the inner wall of the positioning plate 31, and water outlet holes 33 arranged in a ring on the outer walls of the positioning plate 31 and the rotating plate 34. The positioning plate 31 is fixed and adapted to the internal space of the handheld shower head 16. It has a certain space inside for the rotating plate 34 to rotate. Both of them have water outlet holes 33 arranged in a ring on their outer walls. Sufficient space needs to be reserved between two adjacent rows of water outlet holes 33 to ensure the opening and distribution of the sliding groove 32 and the inclined groove 35.

[0046] The driving component 21 also includes a rotating block 211 disposed on the outer wall of the handheld shower head 16. The rotating block 211 is fixedly connected to the rotating block 212. A positioning ring 215 is disposed on the end face of the positioning disc 31. A first spring 216 is disposed on the end face of the positioning ring 215. A first guide block 214 is disposed at the end of the first spring 216. The first guide block 214 can slide along the first guide groove 213. A driving rod 21 is disposed on the outer wall of the first guide block 214. 7. The first guide groove 213 is continuously composed of symmetrically distributed straight grooves and arc grooves. The drive rod 217 passes through the positioning ring 215 and contacts the outer wall of the moving block 218. The first spring 216 surrounds the outside of the drive rod 217. The outer side of the outer receiving plate 221 is provided with a first guide plate 2110 arranged in a ring. The outer side of the first guide plate 2110 is provided with a conveying plate 2112. The outer wall of the conveying plate 2112 is provided with a second clearance groove 2116. The end face of the conveying plate 2112 is provided with a cleaning cylinder 2113 adapted to the water outlet 33. Among them, the twisting block 2 11 is located on the outer surface of the handheld shower head 16 and is fixedly connected to the rotating block 212. Similarly, the position where the rotating block 211 contacts the handheld shower head 16 also needs to be waterproofed. The positioning ring 215 is in a fixed state and is fixed on the inner end face of the positioning plate 31, which plays a supporting and guiding role. The first spring 216 drives the first guide block 214 to move along the first guide groove 213, so as to realize the synchronous movement of the moving block 218. When the first spring 216 is in a balanced state, it will cause the first guide block 214 to move to the side of the rotating block 212 close to the rotating block 211.

[0047] The first guide block 214 and the rotating block 212 are designed separately. The end face of the first guide block 214 contacts the first guide groove 213. The first guide block 214 and the drive rod 217 can only move horizontally. The first guide block 214 is driven to move along the first guide groove 213 by the elastic force of the first spring 216. The moving block 218 is moved synchronously by the contact between the drive rod 217 and the moving block 218. The first guide plate 2110 and the conveying plate 2112 are both designed in three sets. The conveying plate 2112 is fan-shaped. The conveying plate 2112 is used to adjust the blocking range of the water outlet hole 33 on the surface of the positioning disk 31.

[0048] A first clearance groove 2111 is formed on the outer wall of the first guide plate 2110. The first clearance groove 2111 needs to have a certain length. When the spray range is at its minimum, the second guide plate 2115 is located on the side of the first clearance groove 2111 away from the screw block 211. The extra stroke of the first clearance groove 2111 can provide a certain space for the throttling plate 226 to expand when the moving block 218 just starts to move, so as to avoid interference between the throttling plate 226 and the conveying plate 2112.

[0049] The rotation of the rotating block 212 causes the moving block 218 to move back and forth, providing driving force for the radial movement of the throttling disc 226. By moving multiple throttling discs 226, the spray range of the water outlet 33 and the position of the rotating disc 34 are adjusted, so that the spray range and water pressure are adaptively adjusted to ensure the comfort of people when bathing.

[0050] Furthermore, the shower assembly 1 also includes a mounting console 11, which is fixedly mounted on the outer wall of the positioning frame 12. A top-mounted shower head 13 is mounted at the end of the positioning frame 12, and a water pipe 15 connects to the lower end of the positioning frame 12. The mounting console 11 is used to control the water flow and temperature. The top-mounted shower head 13 works in conjunction with a handheld shower head 16 to provide multiple showering options. Water is delivered to either the top-mounted shower head 13 or the handheld shower head 16 via the water pipe 15 to meet showering needs.

[0051] Preferably, an adjusting block 14 is slidably connected to the outer wall of the positioning frame 12, and the end face of the handheld shower head 16 is connected to the water pipe 15. The handheld shower head 16 can be embedded in the inner side of the adjusting block 14. The adjusting block 14 can move up and down along the positioning frame 12, and at the same time, it can position the handheld shower head 16, so as to realize the quick adjustment of the shower height of the handheld shower head 16.

[0052] When in use, the control console 11 and the positioning frame 12 are fixed. Water flows through the control console 11 into the positioning frame 12 and the water pipe 15 respectively. Showering can be performed through the overhead shower head 13 and the hand shower head 16 respectively. The spray height of the hand shower head 16 can be adjusted by controlling the adjusting block 14 to slide along the outer surface of the positioning frame 12.

[0053] Taking the case where the spray range is at its maximum and needs to be reduced as an example, the rotating block 211 is manually controlled to rotate. The rotating block 211 drives the rotating block 212 to rotate synchronously. Since the first guide block 214 and the drive rod 217 can only maintain horizontal movement due to the limitation of the positioning ring 215, when the rotating block 212 rotates, the arc groove in the first guide groove 213 drives the first guide block 214 to move along the arc groove towards the side closer to the positioning ring 215. Since the first guide block 214 is fixedly connected to the drive rod 217, the drive rod 217 moves forward synchronously. The drive rod 217 drives the moving block 218 to move synchronously away from the rotating block 211. If the rotating block 211 continues to rotate, the first guide block 214 will enter the first guide groove 213. The straight groove inside uses the first spring 216 to reset the first guide block 214. The first guide block 214 will gradually be inserted into the limiting groove 219 at different positions when the person rotates the screw block 211. During the movement of the first guide block 214, the elastic force of the first spring 216 is to move the first guide block 214 closer to the screw block 211. At this time, the first guide block 214 is embedded in the limiting groove 219. Only when the person controls the screw block 211 to rotate will the first guide block 214 continue to slide along the arc groove of the first guide groove 213. When the first guide block 214 moves to the straight groove of the first guide groove 213, it will be reset along the straight groove by the elastic force of the first spring 216, so as to realize the continuous rotation of the screw block 211.

[0054] In summary, the combination of overhead shower head 13 and handheld shower head 16 meets the different showering needs of individuals. At the same time, the spray height of the handheld shower head 16 can be adjusted by raising and lowering the control adjustment block 14. The rotation of the screw block 211 is converted into the power for the horizontal movement of the moving block 218 by the rotating block 212. The movement of the moving block 218 provides the power input for the synchronous start of the extension member 22 and the second adjustment component 3. Example 2

[0055] Reference Figures 4-7 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a power transmission method for the adjustment mechanism of a shower.

[0056] Preferably, a positioning plate 2114 is fixedly connected to the end face of the conveyor plate 2112, a first clearance groove 2111 is provided on the outer wall of the first guide plate 2110, and a second guide plate 2115 is movably connected to the inner side of the first guide plate 2110. The two ends of the second guide plate 2115 can slide along the inner side of the first clearance groove 2111 and the positioning plate 2114, respectively. The conveying and distribution of the cleaning cylinder 2113 corresponds to the water outlet 33 corresponding to the conveying plate 2112, and the cleaning cylinder 2113 has a certain length to clean the inner wall of the water outlet 33. It should be noted that as the moving block 218 moves horizontally to a certain position, the throttling plate 226 moves radially to the edge of the handheld shower head 16. The extra stroke of the first clearance groove 2111 ensures that the cleaning cylinder 2113 remains stationary during the initial stroke of the throttling plate 226. Only after the extra stroke of the first clearance groove 2111 is completed will the conveying plate 2112 move, allowing the cleaning cylinder 2113 to be embedded in the water outlet 33.

[0057] The second clearance groove 2116 is located at the center of the surface of the conveyor plate 2112, with one end open to the outside, to ensure the normal passage of the second guide plate 2115. It should be noted that the bottom wall of the second guide plate 2115 is integrally formed with an extension rod, which contacts the inner wall of the positioning plate 2114. The positioning plate 2114 on each side has two sets of designs, thereby driving the conveyor plate 2112 to move. Both ends of the second guide plate 2115 are provided with limiting structures, such as the extension rod mentioned above, to prevent it from falling off. The inner wall of the handheld shower head 16 is provided with a fixing rod, and the conveyor plate 2112 slides along the rod, which plays a guiding role and ensures the normal movement of the conveyor plate 2112. In addition, the outer side of the second guide plate 2115 near the first guide plate 2110 is also provided with a corresponding guiding structure, such as the fixing rod mentioned above. The fixing rod is fixed inside the handheld shower head 16, and the second guide plate 2115 is rotatably connected to the fixing rod, thereby playing a guiding and limiting role, so that the second guide plate 2115 rotates around the rod as the axis.

[0058] The rest of the structure is the same as in Example 1.

[0059] In use, when the moving block 218 is driven by the drive rod 217 to move away from the rotating block 211, the first moving block 218, the outer plate 221, and the first guide plate 2110 are fixedly connected, causing the first guide plate 2110 to move synchronously to that side along with the moving block 218. Since there is a certain distance between the first clearance groove 2111 and the second guide plate 2115 at this time, this distance ensures that the throttling disc 226 moves radially with the horizontal movement of the moving block 218, thus increasing the spray range. Only after the throttling disc 226 has moved to a certain position will the inner wall of the first clearance groove 2111 contact the second guide plate 2115. The guide plate 2115 is connected to the second guide plate 2115, thereby driving the second guide plate 2115 to move. The movement of the second guide plate 2115 within the positioning plate 2114 causes the conveying plate 2112 to move horizontally, thereby enabling the cleaning cylinder 2113 to complete the cleaning of the water outlet 33. At this time, the throttling disc 226 has moved to the outside of the water outlet 33 and no longer blocks the water outlet 33. It should be noted that there is still a distance between the outermost water outlet 33 and the inner edge of the handheld shower head 16 for the throttling disc 226 to stop. This design ensures that the cleaning effect of the second adjustment component 3 will only be triggered when the screw block 211 is rotated to its limit. Example 3

[0060] Reference Figure 5 and Figure 12 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a method for adjusting the spray range.

[0061] Specifically, the extension member 22 also includes a protrusion 223 integrally formed on the end face of the outer plate 221. A connecting plate 224 is rotatably connected to the outer wall of the protrusion 223, and a fixing block 225 is fixedly connected to the end face of the throttle plate 226. The number of protrusions 223 corresponds to the number of throttle plates 226. At the same time, the protrusions 223 ensure sufficient space for the installation of the connecting plate 224. The connecting plate 224 connects the protrusions 223 and the fixing block 225. Both ends of the connecting plate 224 are rotatably connected, so that the direction of the connecting plate 224 can be changed according to the movement of the outer plate 221.

[0062] Furthermore, the end of the connecting plate 224 is rotatably connected to the outer wall of the fixed block 225, and the outer wall of the sliding block 227 is fixedly connected to the second guide block 222. The radial displacement of the throttle disc 226 is determined by the length of the connecting plate 224. Therefore, the inclination and length of the connecting plate 224 must ensure that the throttle disc 226 has sufficient radial travel. The sliding block 227 has concave sides, which allows the connection of the sliding block 227 to the outer wall of the positioning disc 31 to achieve both sliding and limiting effects.

[0063] The rest of the structure is the same as in Example 2.

[0064] During use, the operation of the drive component 21 causes the moving block 218 to move. As the moving block 218 moves, the outer connecting plate 221 moves synchronously with it. Since the sliding block 227 is limited by the positioning plate 31, when the outer connecting plate 221 moves away from the positioning plate 31, the connecting plate 224 begins to gradually tilt, thereby driving the fixed block 225 and the throttling plate 226 to move away from the inner edge of the handheld shower head 16. The sliding block 227 on the outer wall of the throttling plate 226 slides along the sliding groove 32. Since the throttling plate 226 is in contact with the outer wall of the positioning plate 31, when the throttling plate 226 moves inward, it will increase the area of ​​blocking the water outlet 33 on the outer wall of the positioning plate 31, thereby reducing the spray range. At the same time, the movement of the sliding block 227 provides power input to the second adjustment component 3.

[0065] In summary, the movement of the moving block 218 is converted into the synchronous movement of the external plate 221 by the driving component 21, and the radial movement of the throttle plate 226 is achieved by the movement of the connecting plate 224. Thus, the spray range is adjusted by the movement of the throttle plate 226, while providing power input to the second adjustment component 3. Example 4

[0066] Reference Figure 4 and Figure 10 This is the fourth embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a method for adjusting water flow pressure.

[0067] Specifically, the second adjustment component 3 also includes a sliding groove 32 formed on the outer wall of the positioning disk 31 near the extension member 22, and an inclined groove 35 formed on the outer wall of the rotating disk 34. The sliding groove 32 is formed on one side of the outer surface of the positioning disk 31. When the spray range is at its minimum, the channel opened by the water outlet holes 33 on the outer walls of the rotating disk 34 and the positioning disk 31 is at its minimum. At this time, the water outlet space is at its minimum and the water pressure is at its maximum.

[0068] Furthermore, the sliding groove 32 and the inclined groove 35 are positioned correspondingly. The sliding block 227 can slide along the sliding groove 32, and the second guide block 222 can slide along the inclined groove 35. The inclined groove 35 is also formed on one side of the outer surface of the rotating disk 34. The number and design position of the sliding groove 32 and the inclined groove 35 correspond to the sliding block 227. The inclined groove 35 needs to have a certain depth to ensure that the second guide block 222 can slide stably along the inclined groove 35, thereby driving the rotation of the rotating disk 34.

[0069] The rest of the structure is the same as in Example 3.

[0070] In use, when the throttling disc 226 and the sliding block 227 move synchronously away from the inner edge of the handheld shower head 16, the sliding block 227 drives the second guide block 222 to slide along the inclined groove 35. The second guide block 222 is simultaneously limited by the sliding groove 32 and the inclined groove 35. At the same time, the first guide block 214 is locked in the limiting groove 219 to ensure the stability of the position of each component in the extension member 22 and the second adjustment assembly 3. The contact between the second guide block 222 and the inclined groove 35 causes the rotating disc 34 to rotate, thereby gradually blocking and sealing the water outlet 33 on the outer wall of the positioning disc 31, reducing the water outlet range and increasing the water pressure. When the screw block 211 continues to rotate, the first guide block 214 resets. Therefore, by continuously rotating the screw block 211, the spray range and water pressure changes can be continuously and synergistically adjusted.

[0071] In summary, the rotation of the rotating disk 34 within the positioning disk 31 is achieved by the movement of the throttling disk 226 and the sliding block 227 in the extension member 22. When the throttling disk 226 moves closer to the edge of the shower head, the spray range increases, and the water outlet formed by the water outlet holes 33 on the surface of the positioning disk 31 and the rotating disk 34 becomes larger, resulting in lower water pressure. When the throttling disk 226 moves further away from the edge of the shower head, the spray range decreases, but the water outlet formed by the water outlet holes 33 on the surface of the positioning disk 31 and the rotating disk 34 becomes smaller, resulting in higher water pressure. The coordinated adjustment of the spray range and water pressure ensures the comfort of the person showering.
