Description

Technical Field

[0001] The present invention relates to the technical field of flow diversion, and in particular to a flow diversion control structure and a top spray shower. Background Art

[0002] Traditional overhead shower heads mostly adopt a single cavity diversion design, and the nozzle and the water outlet are connected by a rigid pipe, which results in a single water output and makes it difficult to adjust the water volume according to the user's feelings. Although some overhead shower heads have a diversion control structure inside to adjust the water output in the shower head, they only adjust the water output and it is difficult to adjust the water output, water outlet area and water outlet height at the same time. Therefore, a diversion control structure for an overhead shower head is needed. Summary of the invention

[0003] The object of the present invention is to overcome the above-mentioned shortcomings and provide a diversion control structure and an overhead shower head, which can ensure the diversion of water flow during adjustment while ensuring that the height of the overhead shower head is adjustable, and the operation is simple and convenient.

[0004] In the first aspect, the present invention provides a diversion control structure, which includes a spiral water inlet pipe, an inner water inlet part and an outer water inlet part, one end of the spiral water inlet pipe is connected to the inner water inlet part and water is injected into the inner water inlet part, the outer water inlet part includes an outer ring sleeve, a connecting channel and a connecting ring, the inner water inlet part is nested in the outer ring sleeve, the upper and lower sides of the inner ring wall of the connecting ring are engaged with the spiral water inlet pipe so that a flow cavity is left between the inner ring wall of the connecting ring and the spiral water inlet pipe, and the two connecting channels respectively connect the flow cavity and the outer ring sleeve.

[0005] The side wall of the spiral water inlet pipe is provided with a plurality of diversion holes and a plurality of movable switch components corresponding to the diversion holes are provided inside the spiral water inlet pipe. The movable switch component includes a sealing plate, a movable ring and a first spring. The bottom of the sealing plate is rotatably connected to the side wall of the spiral water inlet pipe. The inner ring of the spiral water inlet pipe is provided with a limiting convex portion. The movable ring is coaxially arranged on the inner ring of the limiting convex portion and the two are connected by a first spring. In the absence of external force, the movable ring abuts against the sealing plate to cover the diversion hole. A telescopic top support component is provided in the circulation cavity. When the telescopic top support component moves to the position of the diversion hole, it pushes open the sealing plate so that part of the water flows from the spiral water inlet pipe into the circulation cavity.

[0006] Furthermore, the diversion control structure also includes a mounting seat and a rotating drive component. The other side of the spiral water inlet pipe is rotatably connected to the water inlet main pipe. The rotating drive component is arranged on the top of the mounting seat and is connected to drive the spiral water inlet pipe to rotate. The external water inlet component is slidingly connected to the side wall of the mounting seat. The rotation of the spiral water inlet pipe causes the external water inlet component to move up and down.

[0007] Furthermore, the telescopic top support assembly includes a limit sleeve, a movable column and a second spring. The limit sleeve is fixed to the side wall of the flow cavity, the movable column is nested in the limit sleeve and the two are connected by the second spring. A universal ball is embedded in the end of the movable column close to the spiral water inlet pipe. When it does not move to the diversion hole, the universal ball abuts against the threaded wall on the surface of the spiral water inlet pipe to cause the movable column to shrink in the limit sleeve.

[0008] Furthermore, the internal water inlet component includes a water outlet plate, several of which are arranged in a ring around the spiral water inlet pipe, a water injection chamber is provided in the water outlet plate, and the water inlet of the water injection chamber is located at the bottom of the spiral water inlet pipe, and several water outlet nozzles are vertically arranged on the side wall of the water outlet plate, and a flow limiting strip is provided in the water injection chamber, which covers the lateral surface of the water injection chamber. The water pressure in the water injection chamber is changed to make the flow limiting strip move up and down to adjust the highest water level in the water injection chamber.

[0009] Furthermore, the water outlet nozzle is made of rubber.

[0010] Furthermore, the inner water inlet member also includes a water injection ring, the bottom ring of which is provided with a plurality of water outlet channels, and the top of the water outlet channel is connected with the top of the water outlet plate.

[0011] Furthermore, a plurality of water outlets are provided at the bottom of the outer ring sleeve.

[0012] Furthermore, a plurality of water inlet holes are provided on the side wall of the spiral water inlet pipe, and a rotary joint covering the water inlet holes is provided between the water inlet main pipe and the spiral water inlet pipe.

[0013] Furthermore, the threaded wall of the spiral water inlet pipe is an inclined slope on both sides of the diversion hole.

[0014] In a second aspect, the present invention provides a top spray shower head, comprising the above-mentioned diversion control structure.

[0015] By adopting the above technical solution, the beneficial effects of the present invention are: 1. The present invention arranges a spiral water inlet pipe to realize water inlet into the flow channel of the inner water inlet part, and enables the outer water inlet part to engage with the thread on the outer side of the spiral water inlet pipe to realize the height adjustment, thereby establishing a height-adjustable tributary; a plurality of diversion holes are arranged on the side wall of the spiral water inlet pipe, and a movable switch assembly is arranged corresponding to each diversion hole, and the sealing plate is pushed open by the telescopic top support assembly to drive the movable ring to move downward, and then the gap between the sealing plate and the diversion hole is further expanded in conjunction with the downward water pressure, so as to realize the circulation of the tributary at the target position, and realize its connectivity control under the premise of realizing the height adjustment of the tributary, and the operation steps are simple.

[0016] 2. The present invention facilitates the installation and fixation of the shower head by providing a mounting seat, and then allows the spiral water inlet pipe to rotate, making the entire structure more streamlined; by providing a universal ball at one end of the movable column, it is convenient for the connecting ring to abut against the spiral wall of the spiral water inlet pipe, and at the same time cooperate with the inclined slope. When there is no water flowing in the spiral water inlet pipe, the inclined slope cooperates with the movable ring with an upward restoring force to cause the movable seat to shrink in the limiting sleeve.

[0017] 3. The present invention avoids the impact force of vertically falling water on the user by arranging the water outlet on the side wall of the inner water inlet, and at the same time arranges a flow limiting strip in the water injection chamber. The water level in the water injection chamber is controlled by the gravity of the flow limiting strip itself and the friction between it and the side wall of the water injection chamber, thereby extending the reaction speed of the inner water inlet water spray to water inlet and water stop, and realizing slow water outlet of the inner water inlet. At the same time, a water injection ring is arranged to realize the adjustment of different water flow levels by controlling the water pressure, and the adjustment method is simple.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but are not used to limit the present invention.

[0027] Reference Figure 1-7 In a first aspect, the present invention provides a diversion control structure, comprising a spiral water inlet pipe 1, an inner water inlet member 3 and an outer water inlet member 2.

[0028] One end of the spiral water inlet pipe 1 is connected to the inner water inlet part 3 and water is injected into the inner water inlet part 3. The outer water inlet part 2 includes an outer ring sleeve 21, a connecting channel 22 and a connecting ring 23. The inner water inlet part 3 is nested in the outer ring sleeve 21, and a plurality of water outlets are provided at the bottom of the outer ring sleeve 21. The upper and lower sides of the inner ring wall of the connecting ring 23 are meshed with the spiral water inlet pipe 1 so that a flow cavity is left between the inner ring wall of the connecting ring 23 and the spiral water inlet pipe 1. The two connecting channels 22 are connected to the flow cavity and the outer ring sleeve 21 respectively. When working, the spiral water inlet pipe 1 is either rotated, and the outer water inlet part 2 is height-adjusted under the action of the connecting ring 23 and the spiral water inlet pipe 1. For example, the diversion control structure also includes a mounting seat 4 and a rotating drive member 5. The other side of the spiral water inlet pipe 1 is rotatably connected to the water inlet main pipe 6. The connection method is: a plurality of water inlet holes are provided on the side wall of the spiral water inlet pipe 1, and a rotating joint covering the water inlet holes is provided between the water inlet main pipe 6 and the spiral water inlet pipe 1. The rotating driving member 5 is arranged on the top of the mounting seat 4 and connected to drive the spiral water inlet pipe 1 to rotate. The outer water inlet member 2 is slidably connected to the side wall of the mounting seat 4. The rotation of the spiral water inlet pipe 1 causes the outer water inlet member 2 to move up and down. Alternatively, the outer water inlet member 2 is rotated by an external rotating motor, and the spiral water inlet pipe 1 can move up and down to adjust the height of the inner water inlet member 3.

[0029] In order to achieve water flow control between the two components under the premise that the relative height of the inner water inlet part 3 and the outer water inlet part 2 changes, the side wall of the spiral water inlet pipe 1 is provided with a plurality of diversion holes 11 and a plurality of movable switch components 12 corresponding to the diversion holes 11 are provided inside the spiral water inlet pipe 1. The movable switch is used to flexibly control the opening and closing of the diversion holes 11. Specifically, the movable switch component 12 includes a sealing plate 121, a movable ring 122 and a first spring 123. The bottom of the sealing plate 121 is rotatably connected to the side wall of the spiral water inlet pipe 1, and the contact portion between the sealing plate 121 and the diversion hole 11 can be made of a soft material. The inner ring of the spiral water inlet pipe 1 is provided with a limiting protrusion 13, and the movable ring 122 is coaxially arranged on the inner ring of the limiting protrusion 13 and the two are connected by a first spring 123. When there is no external force, the first spring 123 urges the movable ring 122 to abut against the sealing plate 121 to cover the diversion hole 11. A telescopic top support component 231 is provided in the circulation cavity, refer to Figure 4 When the telescopic supporting assembly 231 moves to the position of the diversion hole 11, the sealing plate 121 is pushed open so that part of the water flows from the spiral water inlet pipe 1 into the flow cavity, and the gap between the sealing plate 121 and the diversion hole 11 increases under the action of the water flow.

[0030] The telescopic support assembly 231 specifically includes a limiting sleeve 2311, a moving column 2312 and a second spring 2313. The limiting sleeve 2311 is fixed to the side wall of the circulation cavity, the moving column 2312 is nested in the limiting sleeve 2311 and the two are connected by the second spring 2313. A universal ball is embedded in the end of the moving column 2312 close to the spiral water inlet pipe 1. When it is not moved to the diversion hole 11, the universal ball abuts against the threaded wall on the surface of the spiral water inlet pipe 1 so that the moving column 2312 shrinks in the limiting sleeve 2311. In order to realize the switching of the telescopic support assembly 231 on the surface of the spiral water inlet pipe 1 and the sealing plate 121, the threaded wall of the spiral water inlet pipe 1 is made to be an inclined slope on both sides of the diversion hole 11. Before switching, it is necessary to first turn off the water source to reduce the gap between the sealing plate 121 and the diversion hole 11, and then start the rotating drive member 5 to control the universal ball to move along the inclined slope.

[0031] In order to reduce the water attack force of the top-spray shower, the water outlet direction of the inner water inlet 3 is changed, specifically, the inner water inlet 3 includes a water outlet plate 34, several water outlet plates 34 are arranged around the spiral water inlet pipe 1, a water injection cavity is provided in the water outlet plate 34, and the water inlet of the water injection cavity is located at the bottom of the spiral water inlet pipe 1, and several water outlet nozzles 341 are arranged vertically on the side wall of the water outlet plate 34. In order to increase the water flow selection of the inner water inlet 3 and extend its water outlet reaction time, a flow limiting strip 342 is provided in the water injection cavity, and the flow limiting strip 342 covers the lateral surface of the water injection cavity. The water pressure in the water injection cavity is changed so that the flow limiting strip 342 can move up and down under the action of the water pressure, thereby realizing the adjustment of the highest water level in the water injection cavity. Among them, the water outlet nozzle 341 is made of rubber material. Because the nozzle is in a horizontal state, the water outlet nozzle 341 will bend when there is no water, preventing the top-spray shower from leaking.

[0032] In order to further increase the water volume selection and spraying area of ​​the shower, the inner water inlet 3 also includes a water injection ring 35. The bottom ring of the water injection ring 35 is provided with a plurality of water outlet channels. The top of the water outlet channel is connected with the top of the water outlet plate 34. After filling the entire water outlet plate 34, the water flow will overflow from the top of the water outlet plate 34 to reach the water injection ring 35 for discharge.

[0033] In a second aspect, the present invention provides a top spray shower head, comprising the above-mentioned diversion control structure.

[0034] Working principle: When in use, the water inflow of the water inlet main pipe 6 is adjusted as needed. As the water pressure increases, the flow limiting strip 342 moves upward to gradually increase the water outflow of the inner water inlet part 3. When the height is adjusted under the premise of using the outer water inlet part 2, the water source is first turned off, and then the rotating driving part 5 is controlled to start adjusting the position of the outer water inlet part 2. When the connecting ring 23 reaches the diversion hole 11, the telescopic top support assembly 231 will open the sealing plate 121 and then start the water source, and the diversion is realized under the further action of the water source.
