Description

Technical Field

[0001] This utility model belongs to the field of shower technology, and in particular relates to an adjustable flow push-button structure and a shower. Background Technology

[0002] In the bathroom fixtures industry, the core water circuit control of products such as showerheads and faucets relies on various valve cores, each with a clearly defined function: including valve cores responsible for turning the water on and off, valve cores for regulating flow, valve cores for controlling water temperature, and valve cores for switching water circuits (such as switching between overhead and handheld showers). These valve cores work together to achieve the product's basic functions and diverse user experiences.

[0003] As consumer demand upgrades, shower products are becoming increasingly feature-rich—users not only need basic on / off and temperature control, but also expect complex functions such as flow rate adjustments. However, existing flow rate regulation largely relies on dedicated flow valve cores, and their adjustment methods are mostly "fixed-level" (such as only 2-3 flow rates), which makes it difficult to meet the diverse needs of users in various scenarios—for example, the small flow rate needed for children playing in the water, the gentle medium flow rate for daily rinsing, and the large flow rate for quick cleaning, etc. Fixed levels cannot achieve precise adaptation; moreover, after long-term use, the seals inside the valve core are prone to wear, leading to decreased adjustment accuracy, leakage, or even functional failure, and durability needs to be improved.

[0004] In addition, existing traditional flow valve cores usually require the addition of an independent flow regulating component inside the valve core. Such components significantly increase the radial or axial dimensions of the valve core, which in turn forces the entire shower casing and installation space to expand simultaneously, resulting in a larger product size and limited adaptability to various scenarios.

[0005] Based on this, the present invention provides a novel adjustable flow push-button structure and shower to overcome the above-mentioned defects. Utility Model Content

[0006] One objective of this invention is to provide an adjustable flow rate push-button structure, which achieves flow rate adjustment through a mechanical linkage of "linear sliding → gear meshing transmission → rotational adjustment of flow area".

[0007] This utility model adopts the following technical solution: an adjustable flow push-button structure, installed inside the outer casing of a shower, comprising:

[0008] A flow regulating chamber is disposed within the outer shell, and a flow regulating receiving cavity is formed within the flow regulating chamber. The flow regulating receiving cavity is provided with an inlet and an outlet.

[0009] A flow regulating component is rotatably disposed within the flow regulating cavity. The flow regulating component is provided with a flow regulating part and a sector gear part that is linked to the flow regulating part. The flow regulating part is disposed opposite to the outlet of the flow regulating cavity.

[0010] A sliding drive assembly is slidably disposed on the housing in a straight line, and the sliding drive assembly is provided with a rack structure that meshes with the sector gear section;

[0011] Specifically, by pushing the sliding drive component, the flow regulating component is driven to rotate through the meshing transmission between the rack structure and the sector gear, thereby changing the overlapping flow area between the flow regulating part and the outlet to achieve flow regulation.

[0012] Furthermore, the bottom inner wall of the flow regulating chamber of the flow regulating compartment is provided with internal threads;

[0013] The adjustable flow push-button structure also includes:

[0014] The connector includes an integrally formed cylindrical part and a wrench latching part. The outer wall of the cylindrical part is provided with an external thread that matches the internal thread at the bottom of the flow regulating cavity. The wrench latching part is used to engage with a wrench.

[0015] Furthermore, a first limiting surface is provided at the bottom of the internal thread of the flow regulating chamber;

[0016] The cylindrical part of the connector extends outward from the connection point with the wrench latch to form a first limiting platform. A second limiting surface is provided on the side of the first limiting platform near the cylindrical part, and the second limiting surface abuts and cooperates with the first limiting surface of the flow regulating chamber.

[0017] Furthermore, the adjustment component includes:

[0018] The flow regulating shaft is provided with a flow regulating connecting section, a middle support section and a power connecting section in sequence along the axial direction. The top end of the flow regulating connecting section is rotatably mounted on the top of the flow regulating chamber, and its outer wall extends outward to form the flow regulating part. The middle support section is mounted in the axial through-center hole of the connector and rotates with the connector.

[0019] An adjusting rotating block is provided, with a through hole in the middle that is adapted to the power connection section of the flow regulating shaft. The power connection section of the flow regulating shaft is inserted into the through hole, so that the adjusting rotating block is fixedly connected to the flow regulating shaft. The sector gear portion is formed on the outer wall side of the adjusting rotating block.

[0020] Furthermore, the middle outer periphery of the middle support section of the flow regulating shaft extends outward to form a limiting ring; the limiting ring is provided with a third limiting surface on the side near the connector, and the third limiting surface abuts and cooperates with the top surface of the connector.

[0021] Furthermore, the outer wall of the middle support section of the flow regulating shaft located inside the central hole of the connector has at least one annular groove, and a sealing ring is embedded in the annular groove.

[0022] Furthermore, the adjusting block has an outward protrusion on the side facing the connector.

[0023] Furthermore, a limiting post is provided inside the outer shell;

[0024] The slip drive assembly includes:

[0025] An adjusting slider is slidably assembled inside the housing. The adjusting slider has the rack structure on the side facing the flow control component. A limiting groove adapted to a limiting post is opened on the adjusting slider. The limiting post passes through the limiting groove to limit the sliding stroke of the adjusting slider.

[0026] Furthermore, a sliding groove is provided on the outer shell along the sliding direction of the adjusting slider;

[0027] The slip drive assembly further includes:

[0028] The flow control handwheel has a D-shaped retaining shaft at one end facing the adjustment slider. The D-shaped retaining shaft passes through the sliding groove of the outer casing and engages with the D-shaped retaining groove on the adjustment slider.

[0029] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0030] The adjustable flow rate push-button structure of this utility model achieves flow rate adjustment through a mechanical linkage of "linear sliding → gear meshing transmission → rotational adjustment of the flow area", the specific process of which is as follows:

[0031] First, the user pushes the sliding drive component in a straight line (such as pushing it to the left or right), and the sliding drive component moves in a straight line along the preset trajectory of the outer shell.

[0032] Next, the rack structure of the sliding drive assembly meshes with the sector gear of the flow regulating assembly. When the sliding drive assembly slides in a straight line, the rack structure drives the sector gear and the flow regulating assembly to rotate around the central axis of the flow regulating assembly through tooth surface meshing, realizing the power conversion from "linear motion to rotational motion".

[0033] However, as the flow regulating component rotates synchronously with the sector gear, the relative position of its flow regulating section and the outlet of the flow regulating chamber changes: if the overlap area between the flow regulating section and the outlet increases, the water flow through the outlet is obstructed more, and the flow rate decreases; if the overlap area decreases, the water flow is obstructed less, and the flow rate increases. Throughout the regulation process, the overlap area changes continuously with the pushing distance, achieving stepless flow rate regulation. Correspondingly, external water flows into the flow regulating chamber from the inlet of the flow regulating chamber, flows out after passing through the non-overlapping area between the flow regulating section and the outlet, and completes the water output after flow rate regulation.

[0034] In this invention, the adjustable flow push-button structure allows water to flow through the overlapping cross-sectional area formed by the flow adjustment part of the flow regulating component and the outlet of the flow regulating chamber. When the sliding drive component is pushed, the flow regulating component is rotated via gear and rack meshing, causing the overlapping cross-sectional area to change continuously (increasing or decreasing), thereby achieving precise adjustment of the water flow. Furthermore, this flow adjustment has no fixed settings; users can adjust the flow to a water-saving or comfortable rinsing setting as needed, making it convenient to operate and adaptable to diverse usage scenarios.

[0035] On the other hand, the gear and rack meshing transmission adopts a rigid contact structure, which ensures stable and efficient power transmission and effectively avoids transmission failure problems that occur after long-term use. At the same time, the rotational motion of the flow regulating component and the linear motion of the sliding drive component are guided and constrained by preset trajectories, which can significantly reduce the offset wear between components, thereby avoiding the jamming failure caused by wear in traditional flow regulating structures and effectively extending the overall service life of the push-button structure.

[0036] The second objective of this utility model is a shower, which includes an outer shell and a shower body disposed within the outer shell; the shower body includes a plurality of valve body assemblies and the aforementioned adjustable flow push-button structure disposed on one side of the valve body assemblies.

[0055] 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 some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0056] The following is in conjunction with the appendix Figure 1 To be continued Figure 11 The present invention will be described in detail with reference to specific embodiments:

[0057] like Figures 1 to 11 As shown, this utility model provides an adjustable flow push-button structure, which is installed inside the outer casing 1 of a shower unit, and includes:

[0058] The flow regulating chamber 2 is disposed inside the outer shell 1. The flow regulating chamber 2 has a flow regulating cavity 20 formed inside it. The flow regulating cavity 20 is provided with an inlet 201 and an outlet 202.

[0059] The flow regulating component 3 is rotatably disposed in the flow regulating cavity 20. The flow regulating component 3 is provided with a flow regulating part 30 and a sector gear part 31 that is linked with the flow regulating part 30. The flow regulating part 30 is disposed opposite to the outlet 202 of the flow regulating cavity 20.

[0060] The sliding drive assembly 4 is slidably disposed on the housing 1 in a straight line direction. The sliding drive assembly 4 is provided with a rack structure 40 that meshes with the sector gear part 31.

[0061] Specifically, by pushing the sliding drive component 4, the flow regulating component 3 is driven to rotate through the meshing transmission between the rack structure 40 and the sector gear 31, thereby changing the overlapping flow area between the flow regulating part 30 and the outlet 202 and realizing flow regulation.

[0062] The adjustable flow rate push-button structure of this utility model achieves flow rate adjustment through a mechanical linkage of "linear sliding → gear meshing transmission → rotational adjustment of the flow area", the specific process of which is as follows:

[0063] First, the user pushes the sliding drive component 4 in a straight line (such as pushing it to the left or right), and the sliding drive component 4 moves in a straight line along the preset trajectory of the outer shell 1.

[0064] Next, the rack structure 40 of the sliding drive assembly 4 is engaged with the sector gear 31 of the flow regulating assembly 3. When the sliding drive assembly 4 slides in a straight line, the rack structure 40 drives the sector gear 31 and the flow regulating assembly 3 to rotate around the central axis of the flow regulating assembly 3 through tooth surface engagement, thereby realizing the power conversion from "linear motion to rotational motion".

[0065] However, as the flow regulating component 3 rotates synchronously with the sector gear 31, the relative position of its flow regulating section 30 and the outlet 202 of the flow regulating chamber 2 changes: if the overlap area between the flow regulating section 30 and the outlet 202 increases, the water flow through the outlet 202 is obstructed more, and the flow rate decreases; if the overlap area decreases, the water flow is obstructed less, and the flow rate increases. Throughout the regulation process, the overlap area changes continuously with the pushing distance, achieving stepless flow rate regulation. Correspondingly, external water flows into the flow regulating cavity 20 from the inlet 201 of the flow regulating chamber 2, flows out after passing through the non-overlapping area between the flow regulating section 30 and the outlet 202, and completes the water output after flow rate regulation.

[0066] In this invention, the adjustable flow push-button structure allows water to flow through the overlapping cross-sectional area formed by the flow regulating part 30 of the flow regulating component 3 and the outlet 202 of the flow regulating chamber 2. When the sliding drive component 4 is pushed, the flow regulating component 3 is rotated via gear and rack meshing, causing the overlapping cross-sectional area to change continuously (increasing or decreasing), thereby achieving precise adjustment of the water flow rate. Furthermore, this flow rate adjustment has no fixed settings; users can adjust the flow rate to the water-saving or comfortable rinsing setting as needed, making it convenient to operate and adaptable to diverse usage scenarios.

[0067] On the other hand, the gear and rack meshing transmission adopts a rigid contact structure, which ensures stable and efficient power transmission and effectively avoids transmission failure problems after long-term use. At the same time, the rotational motion of the flow regulating component 3 and the linear motion of the sliding drive component 4 are guided and constrained by preset trajectories, which can significantly reduce the offset wear between components, thereby avoiding the jamming failure caused by wear in traditional flow regulating structures and effectively extending the overall service life of the push-button structure.

[0068] Furthermore, in some specific embodiments, the bottom inner wall of the flow regulating cavity 20 of the flow regulating chamber 2 is provided with internal threads;

[0069] The adjustable flow push-button structure also includes:

[0070] Connector 5, which includes an integrally formed cylindrical part 50 and a wrench latching part 51, such as Figure 7 As shown, the outer wall of the cylindrical part 50 is provided with an external thread that matches the internal thread at the bottom of the flow regulating cavity 20; the wrench latching part 51 is used to cooperate with the wrench.

[0071] During assembly, by engaging the wrench with the wrench locking part 51 of the connector 5 (e.g., rotating the wrench after it is engaged with the locking part), the cylindrical part 50 can be screwed into the bottom of the flow regulating cavity 20 until the threads are fully engaged and locked, thus achieving a fixed connection between the connector 5 and the flow regulating chamber 2.

[0072] The connector 5 uses a threaded connection, which provides higher connection strength and sealing compared to snap-fit ​​or plug-in methods. This effectively prevents loosening caused by water flow impact and component vibration during long-term use, reducing the risk of leakage. Simultaneously, the pre-tightening force of the threaded connection can be precisely controlled with a wrench to ensure a tight connection. Furthermore, the design of the wrench locking part 51 facilitates assembly and maintenance, eliminating the need for special tools during assembly / disassembly (a regular wrench suffices), reducing production assembly difficulty and subsequent maintenance costs. If the flow regulating component 3 or connector 5 becomes worn, it can be quickly disassembled and replaced with a wrench, improving the product's maintainability.

[0073] Specifically, the bottom of the internal thread of the flow regulating chamber 2 is provided with a first limiting surface 21.

[0074] The cylindrical portion 50 of the connector 5 extends outward from the connection point with the wrench latch portion 51 to form a first limiting platform 52. A second limiting surface 521 is provided on the side of the first limiting platform 52 closest to the cylindrical portion 50. The second limiting surface 521 abuts against the first limiting surface 21 of the flow regulating chamber 2, providing a rigid stop constraint on the "thread insertion depth" of the connector 5 within the flow regulating chamber 2. When the connector 5 is screwed into the flow regulating cavity 20 through the thread, as the insertion depth increases, the second limiting surface 521 eventually fits tightly against the first limiting surface 21. At this point, the connector 5 cannot continue to be screwed in, forming an "assembly position lock." This avoids damage to the thread structure due to over-tightening and also avoids errors caused by loose connections or seal failure due to shallow assembly, ensuring consistent assembly accuracy for different products and meeting standardized production requirements.

[0075] Specifically, an annular sealing groove 53 can be formed on the outer wall of the cylindrical part 50 in the connector 5, and a first sealing ring 54 is embedded in the annular sealing groove 53 to enhance the sealing performance of the connection.

[0076] Furthermore, in some specific embodiments, the adjustment component 3 includes:

[0077] The flow regulating shaft 32 is provided with a flow regulating connection section 321, a middle support section 322, and a power connection section 323 in sequence along the axial direction, as follows: Figure 6 As shown, the top end of the flow regulating connection section 321 is rotatably mounted on the top of the flow regulating chamber 2, and its outer wall extends outward to form the flow regulating part 30. In this embodiment, the flow regulating part 30 is fan-shaped. The middle support section 322 is mounted in the axial through-center hole 55 of the connector 5 and rotates with the connector 5.

[0078] An adjusting rotating block 33 has a through hole 331 in its middle portion that is adapted to the power connection section 323 of the flow regulating shaft 32. The power connection section 323 of the flow regulating shaft 32 is inserted into the through hole 331, thereby fixing the adjusting rotating block 33 to the flow regulating shaft 32. The sector gear portion 31 is formed on the outer wall side of the adjusting rotating block 33. Figure 8 As shown.

[0079] In this embodiment, the power connection section 323 of the flow regulating shaft 32 is a D-shaped shaft, and the through hole 331 of the adjusting block 33 is a D-shaped hole adapted to the D-shaped shaft. Through shape interlocking, a circumferential fixed connection is achieved. Correspondingly, the fit between the D-shaped shaft and the D-shaped hole achieves complete circumferential locking (no relative rotational clearance) through a rigid "plane-plane" fit. That is, when the adjusting block 33 receives the rotational force transmitted by the rack structure 40 through the sector gear part 31, the D-shaped structure can transmit 100% of the torque to the flow regulating shaft 32, ensuring that the two rotate synchronously and avoiding "power slippage" caused by loose key connections, spline wear, etc. This lossless power transmission directly ensures the linear correspondence between "push stroke - rotation angle - flow area", making the flow regulation precise and controllable and avoiding regulation errors caused by transmission lag.

[0080] During operation, the sector gear 31 of the adjusting block 33 meshes with the rack structure 40 of the sliding drive assembly 4. When the user pushes the sliding drive assembly 4, the linear motion of the rack is converted into the rotational motion of the adjusting block 33 through gear meshing. Since the through hole 331 of the adjusting block 33 is adapted to and fixedly connected to the power connection section 323 of the flow regulating shaft 32, the rotational torque of the adjusting block 33 is directly transmitted to the flow regulating shaft 32, causing the flow regulating shaft 32 to rotate synchronously. When the flow regulating shaft 32 rotates, the sector-shaped flow regulating part 30 rotates synchronously with the shaft, and its overlapping area (flow area) with the outlet 202 changes continuously with the rotation angle, realizing stepless adjustment of the flow rate.

[0081] Specifically, the middle outer periphery of the middle support section 322 of the flow regulating shaft 32 extends outward to form a limiting ring 324; the limiting ring 324 has a third limiting surface 3241 on the side near the connector 5, and the third limiting surface 3241 abuts against the top surface of the connector 5. When the third limiting surface 3241 of the limiting ring 324 abuts against the top surface of the connector 5, the axial position of the flow regulating shaft 32 is directly locked (it cannot move downward), and at the same time, it cooperates with the assembly constraint between the top of the flow regulating connecting section 321 and the top of the flow regulating chamber 2 (restricting upward movement), forming a "bidirectional axial positioning", ensuring that the flow regulating part 30 is always within the preset axial cooperation range with the outlet 202, avoiding the decrease in adjustment accuracy or jamming caused by axial movement.

[0082] Specifically, the outer wall of the middle support section 322 of the flow regulating shaft 32, located within the central hole 55 of the connector 5, has at least one annular groove 3221. A second sealing ring 325 is embedded in the annular groove 3221 to enhance the connection sealing. In this embodiment, two annular grooves 3221 are provided, providing multi-stage sealing to enhance the sealing performance.

[0083] More specifically, the adjusting block 33 has an outer protrusion 332 on the side facing the connector 5. The outer protrusion 332 is used to mark the front and back of the adjusting block 33 to prevent the adjusting block 33 from being installed backwards during assembly, thus achieving mechanical error prevention.

[0084] Furthermore, in some specific embodiments, a limiting post 10 is provided inside the outer shell 1.

[0085] The sliding drive component 4 includes:

[0086] An adjusting slider 41 is slidably mounted inside the outer casing 1. The adjusting slider 41 has the rack structure 40 on the side facing the flow control assembly 3. Figure 3 As shown; the adjusting slider 41 is provided with a limiting groove 411 adapted to the limiting post 10. The limiting post 10 passes through the limiting groove 411 to limit the sliding stroke of the adjusting slider 41; that is, when the adjusting slider 41 slides to the limit position, the limiting post 10 abuts against the end of the limiting groove 411 to prevent it from continuing to move and to prevent damage caused by excessive operation.

[0087] Specifically, a sliding groove 11 is provided on the outer shell 1 along the sliding direction of the adjusting slider 41, and the sliding groove 11 is U-shaped.

[0088] The sliding drive assembly 4 also includes:

[0089] The flow control handwheel 42 has a D-shaped retaining shaft 421 at one end facing the adjusting slider 41. The D-shaped retaining shaft 421 passes through the sliding groove 11 of the outer casing 1 and is fitted and engaged with a pre-set D-shaped retaining groove 412 on the adjusting slider 41, thus achieving a fixed connection between the flow control handwheel 42 and the adjusting slider 41. It should be noted that in this invention, the D-shaped retaining shaft 421 is a claw structure, and a flat cut surface is provided on the outer wall of the claw structure to form the D-shaped retaining shaft 421. Figure 4 As shown.

[0090] The sliding groove 11 is formed along the sliding direction of the adjusting slider 41. The contour of the groove directly defines the movement path of the flow regulating handwheel 42. That is, when the user pushes the flow regulating handwheel 42, the D-shaped retaining shaft 421 can only slide in a straight line along the groove, avoiding the flow regulating handwheel 42 from shifting or rotating due to uneven force. The D-shaped retaining shaft 421 and the D-shaped retaining groove 412 achieve complete circumferential fixation through "plane-plane" contact, with no relative rotational gap, ensuring "zero loss" transmission of operating force.

[0091] Specifically, the outer casing 1 is provided with a limiting boss 12 extending along the sliding direction of the adjusting slider 41. Correspondingly, the rack structure 40 of the adjusting slider 41 is fitted to the side wall of the limiting boss 12 to enhance the stability of the sliding.

[0092] The general assembly process of the adjustable flow push-button structure in this utility model is as follows:

[0093] First, a second sealing ring 325 is embedded in the annular groove 3221 of the middle support section 322 of the flow regulating shaft 32, and then the top end of the flow regulating connection section 321 of the flow regulating shaft 32 is rotated and assembled onto the top of the flow regulating chamber 2.

[0094] Next, take the connector 5 and insert the first sealing ring 54 into the annular sealing groove 53 of its cylindrical part 50; align the cylindrical part 50 of the connector 5 with the bottom opening of the flow regulating cavity 20 of the flow regulating chamber 2, so that the external thread on the outer wall of the cylindrical part initially engages with the internal thread at the bottom of the flow regulating cavity 20; then use a regular wrench to engage the wrench locking part 51 of the connector 5, rotate the wrench, and drive the connector 5 to be screwed into the flow regulating cavity 20 along the thread; as it continues to be screwed in until the second limiting surface 521 of the first limiting platform 52 of the connector 5 is completely abutted against the first limiting surface 21 of the flow regulating chamber 2, the axial position of the connector 5 is locked at this time, and at this time, the third limiting surface 3241 on the flow regulating shaft 32 is also just abutted against the top surface of the connector 5.

[0095] Next, take the adjusting block 33 and confirm that it has an outward protrusion 332 on the side facing the connector 5. Align the D-shaped hole of the adjusting block 33 with the D-shaped power connection section 323 of the flow regulating shaft 32. Push the adjusting block 33 along the axial direction of the flow regulating shaft 32 so that the D-shaped shaft is fully inserted into the D-shaped hole, ensuring that the two are in close "plane-plane" contact.

[0096] Then, take the adjusting slider 41 and align its limiting groove 411 with the limiting post 10 of the outer shell to restrict the sliding of the adjusting slider. Adjust the posture of the adjusting slider 41: make the rack structure 40 of the adjusting slider 41 facing the flow control component 3 fit against the side wall of the limiting boss 12 of the outer shell 1 to enhance the sliding stability and avoid lateral shaking, while ensuring that the rack structure 40 of the adjusting slider meshes with the sector gear part 31 of the adjusting block 33.

[0097] Finally, take the flow control handwheel 42, align the D-type retaining shaft 421 with the sliding groove 11 of the outer casing 1 until the end of the retaining shaft is aligned with the D-type retaining groove 412 of the adjusting slider 41, and press the flow control handwheel 42 towards the adjusting slider 41 so that the D-type retaining shaft 421 is fully engaged in the D-type retaining groove 412, ensuring that the two are in "plane-to-plane" contact; then, push and turn the flow control handwheel 42 to check whether its sliding along the sliding groove 11 is smooth, and whether the rack structure 40 of the adjusting slider 41 can accurately mesh with the sector gear part 31 of the flow control component 3.

[0098] The flow regulation principle of the adjustable flow push-button structure in this utility model is as follows:

[0099] 1) The user pushes the flow-regulating handwheel 42 to the leftmost end along the sliding groove 11 of the outer casing 1. When the flow-regulating handwheel 42 is pushed to the left, its D-shaped retaining shaft 421 drives the adjusting slider 41 to move to the left synchronously. The rack structure 40 of the adjusting slider 41 meshes with the sector gear part 31 of the adjusting block 33. The leftward movement of the rack drives the adjusting block 33 to rotate in the positive direction around the axis of the flow-regulating shaft 32. The adjusting block 33 is circumferentially fixed to the D-shaped shaft power connection section 323 of the flow-regulating shaft 32 through the D-shaped hole. Therefore, the rotation of the adjusting block 33 synchronously drives the flow-regulating shaft 32 to rotate. The outer wall of the flow-regulating connection section 321 of the flow-regulating shaft 32 is provided with a sector-shaped flow-through regulating part 30. As the flow-regulating shaft 32 rotates, the overlap area between the flow-through regulating part 30 and the outlet 202 of the flow-regulating chamber 2 reaches its maximum (i.e., the degree of obstruction of the outlet 202 by the flow-through regulating part 30 is the highest, such as...). Figure 10 (As shown). Because the overlapping flow area is the largest, the amount of water flowing out from the outlet 202 of the flow regulating chamber 2 is the smallest, and the flow velocity is at the minimum end, which is suitable for "water saving mode" or "low flow demand for children's shower".

[0100] 2) The user slowly pushes the flow-adjusting handwheel 42 from left to right along the sliding groove 11. Pushing the flow-adjusting handwheel 42 to the right → the D-shaped retaining shaft 421 drives the adjusting slider 41 to move to the right → the rack and pinion structure 40 drives the adjusting rotating block 33 to rotate in the opposite direction. The adjusting rotating block 33 then drives the flow-adjusting shaft 32 to rotate synchronously in the opposite direction → the fan-shaped flow-adjusting part 30 rotates with the shaft, and the overlapping area with the outlet 202 gradually decreases (the degree of obstruction gradually decreases).

[0101] When the flow regulating handwheel 42 is pushed to the far right, the overlap area between the fan-shaped flow regulating section 30 and the outlet 202 is at its minimum (i.e., the obstruction of the outlet 202 by the flow regulating section 30 is almost completely removed, and the outlet 202 is nearly completely open, such as...). Figure 11 As shown in the figure, the water flow from outlet 202 is the largest, and the flow rate is at its maximum, which is suitable for the needs of "quick flushing" and "high flow shower".

[0102] 3) The user slowly pushes the flow-adjusting handwheel 42 from right to left along the sliding groove 11. Pushing the flow-adjusting handwheel 42 to the left → the D-shaped retaining shaft 421 drives the adjusting slider 41 to move to the left → the rack and pinion structure 40 drives the adjusting rotating block 33 to rotate forward. The adjusting rotating block 33 then drives the flow-adjusting shaft 32 to rotate synchronously in the forward direction → the overlapping area of ​​the fan-shaped flow-adjusting section 30 and the outlet 202 gradually increases (the degree of obstruction gradually increases), and the flow rate decreases linearly with the pushing stroke.

[0103] When the flow regulating handwheel 42 is pushed to the leftmost position, the overlap area between the fan-shaped flow regulating section 30 and the outlet 202 returns to its maximum state (i.e., the outlet 202 is most tightly blocked, such as...). Figure 10 As shown), the flow returns to the minimum end, completing a closed loop of adjustment from "large flow to small flow".

[0104] Based on the aforementioned adjustable flow push-button structure, this utility model also provides a shower, which includes a housing 1 and a shower body 6 disposed within the housing 1. The shower body 6 includes multiple valve assembly 60 and the aforementioned adjustable flow push-button structure disposed on one side of the valve assembly 60. In the adjustable flow push-button structure, the inlet 201 of the flow regulating chamber 2 is connected to the main water inlet of the shower, and the outlet 202 of the flow regulating chamber 2 is connected to the main water outlet of the shower, ensuring that the water flow is regulated by the push-button structure before being output through the shower.

[0105] This shower unit possesses at least all the advantages of the aforementioned adjustable flow push-button structure, which will not be elaborated upon here. Furthermore, by placing the adjustable flow push-button structure "sideways" on one side of the valve body assembly 60, rather than integrating it inside the valve body, the push-button structure effectively avoids occupying internal space in the valve body assembly 60—the valve body assembly 60 can retain only its original function without needing to reserve additional space for flow adjustment.

[0106] In addition, if traditional showers need to achieve flow regulation, they usually need to add independent flow regulation components (such as regulating valve cores or baffle structures) inside the valve body. These components will significantly increase the radial or axial dimensions of the valve body, which in turn forces the entire shower casing and installation space to expand simultaneously, resulting in a larger product size and limited applicable scenarios.

[0107] Therefore, this shower unit, through its "external push-button structure" design, achieves flow regulation without altering the original dimensions of the valve body assembly 60, fundamentally avoiding the "bulky" appearance of the valve body and the shower unit as a whole, and more easily meeting the modern bathroom scene's demand for "miniaturized and aesthetically pleasing" products.

[0108] Furthermore, the shower body 6 is provided with multiple spaced positioning grooves 61, and the outer shell 1 is provided with multiple positioning protrusions 13 that correspond one-to-one with the positioning grooves 61, so as to realize the fixed installation of the shower body 6 in the outer shell 1. The installation method is simple and reliable.

[0109] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
