Detailed Implementation

[0031] Please refer to Figures 1 to 6 The arrows in the diagram indicate the direction of water flow. The shower includes a direct switching device A, which includes a main body 1, a water distribution bushing 2, a switching housing 3, and a switching handle 4.

[0032] The main body 1 includes a main body 11 and a main control component 12. The main body 11 is provided with a water inlet 111, an installation groove 112 that passes through and connects to the water inlet 111, a cold water groove 113, and a hot water groove 114. The port of the water inlet 111 is located on the groove wall of the installation groove 112. The main body 11 is also connected to cold and hot water inlets 115 and 116, which are respectively connected to the cold water groove 113 and the hot water groove 114. The main control component 12 is connected to the cold water groove 113, the hot water groove 114, and the water inlet 111 to control the switch, water temperature, and flow rate. The main control component 12 is provided with a main control handle 121. The main control component 12 is located at the front center of the main body 11. The main control handle 121 is located at the front center of the main body 11 for easy user control. The main control component 12 can refer to the prior art.

[0033] The water distribution bushing 2 has an isolation section 21 fixed inside, so that the water distribution bushing 2 forms two back-to-back water distribution channels 22 and 23. Each water distribution channel 22 and 23 is recessed with a water distribution port 221 and 231 that penetrates through the inside and outside. In this specific embodiment, the water distribution bushing 2 is integrally formed. The water distribution bushing 2 can be relatively fixed in the mounting groove 112 of the main body part 1.

[0034] The switching housing 3 is installed in the mounting groove 112 of the main body 1 and sleeved on the outside of the water distribution bushing 2, and the switching housing 3 can rotate relative to the main body 1 and the water distribution bushing 2; the switching housing 3 is provided with water inlets 311 and 312 that penetrate through the inside and outside, and a water distribution cavity 32 that can connect to the water distribution inlet 31 is formed between the switching housing 3 and the water distribution bushing 2. The water inlet 111 connects to the water distribution cavity 32 through the mounting groove 112 and the water inlets 311 and 312 to realize side water inlet; the switching housing 3 is equipped with sealing parts 331 and 332 that can be adapted to seal the water distribution inlets 221 and 231. By rotating the switching housing 3, the sealing parts 331 and 332 can be controlled to seal the water distribution inlets 221 and 231 to realize at least two water distribution paths 22 and 23 switching to connect to the water distribution cavity 32.

[0035] The two water distribution channels 22 and 23 of the water distribution sleeve 2 are respectively an upward-facing first water distribution channel 22 and a downward-facing second water distribution channel 23. The water outlet of the first water distribution channel 22 is a first water outlet 221, and the water outlet of the second water distribution channel 23 is a second water outlet 231. The first water outlet 221 and the second water outlet 231 are spaced apart relative to the axis of the water distribution sleeve 2, and the first water outlet 221 and the second water outlet 231 are circumferentially spaced relative to the water distribution sleeve 2. The switching housing 3 is fixedly equipped with a sealing part 331 that can respectively adapt to the two water outlets 221 and 231. The sealing parts of the first water outlet 221 and the second water outlet 231 are respectively the first sealing part 331 and the second sealing part 332. Due to the axial and circumferential spacing, and the corresponding sealing parts and water outlets, when one sealing part seals one water outlet, the other sealing part and the other water outlet are staggered. For example, when the first sealing part 331 blocks the first water outlet 221, the second sealing part 332 and the second water outlet 232 are staggered. Therefore, the second water outlet 232 connects to the water distribution chamber 22, and water flows out of the second water distribution path 23. Conversely, water flows out of the first water distribution path 22. If necessary, they can be rotated to stagger both, at which time water flows out of both water distribution paths 22 and 23. Furthermore, the switching housing 3 is provided with a first water inlet 311 and a second water inlet 312 spaced vertically, with a central angle of 90 degrees between the first water inlet 311 and the second water inlet 312 to improve the stability of the water path and the convenience of the design.

[0036] The switching housing 3 is provided with an assembly groove 34 that extends through the inside and outside. A retainer 35 is installed in the assembly groove 34. The retainer 35 is provided with a buckle 351. The retainer 35 is fitted into the assembly groove 35 of the switching housing 3 from the outside to the inside, and the buckle 351 supports the inner wall of the switching housing 3. This structure can improve the stability, firmness and convenience of the assembly. The sealing parts 331 and 332 are mounted on the inner wall of the retainer 35. The mounting is as follows: the inner wall of the retainer 35 has a recessed annular groove 352. The sealing parts 331 and 332 have an arc-shaped structure and are fitted within this annular groove 352. The sealing parts 331 and 332 seal against the outer peripheral wall of the water distribution sleeve 2 and surround the water outlets 221 and 231. This structure achieves a seal, improves sealing performance, avoids interference with rotation, and also provides guidance, reducing shaking during rotation. Furthermore, the arc-shaped structure of the inner walls of the sealing parts 331 and 332, adapted to the outer peripheral wall of the water distribution sleeve 2, avoids interference with the rotation of the housing, reduces shaking during rotation, and improves the stability of the seal. This structure facilitates assembly, improves sealing performance, simplifies the structure, and results in a compact design.

[0037] The upper ends of the switching handle 4 and the switching housing 3 are fixedly connected to each other so that the switching housing 3 can be rotated by the switching handle 4; the switching handle 4 includes a sleeve portion that can be fixedly sleeved on the protruding part of the switching housing 3 extending out of the mounting groove 112 and a handle portion 41 protruding outside the sleeve portion.

[0038] In the specific structure: the lower part of the mounting groove 112 of the main body 1 has a first protruding ring 117 protruding inward at the bottom of the groove wall; the water distribution bushing 2 has a lower end located below the switching housing 3, and a second protruding ring 241 protruding outward at the lower end, which rests against the first protruding ring 117; a lower connector 118 is also provided, which is fixed to the lower end of the water distribution bushing 2 and abuts against the bottom surface of the main body 1; the water distribution bushing 2 is fixed in the mounting groove 112 of the main body 1 through the above structure; the lower connector 118 can be threaded to connect the water distribution bushing 2 and the second water distribution channel 23, which is convenient to assemble and can also connect to other components, such as the hose of a handheld shower. The sleeve of the switching handle 4 can be synchronously rotated and sleeved on the upper end of the switching housing 3. If the switching handle has a notch, the outer part of the switching housing has a protrusion, and the protrusion and the notch are adapted to each other. The upper end of the water distribution bushing 2 extends out of the switching housing 3. The water distribution bushing 2 is internally threaded with a first nut 242. The upper part of the switching housing 3 is provided with a third protruding ring 361 facing outward. The third protruding ring 361 rests against the main body 11. The sleeve of the switching handle 4 is internally threaded with a second nut 42. The first nut 242 rests against the second nut 42. The sleeve of the switching handle 4 rests against the third protruding ring 361. The above structure enables the switching housing 3, the water distribution bushing 2 and the switching handle 4 to be axially locked together, which is convenient for assembly.

[0039] A first sealing ring 371 is provided between the upper part of the switching housing 3 and the upper port of the mounting groove 112. A second sealing ring 251 is provided between the lower end of the water distribution bushing 2 and the lower port of the mounting groove 112. A third sealing ring 252 is provided between the upper section of the water distribution bushing 2 and the upper section of the switching housing 3. The third sealing ring 252 is located above the first water distribution port.

[0040] In this specific embodiment of the shower, after the hot and cold water are mixed by the main control component 12, the warm water flows through the water inlet 111 to the water distribution chamber 32 to achieve water inlet from the middle side and water outlet from the top and bottom. The switching handle 4 is rotated 90 degrees. When the switching handle 4 is facing directly forward, water is discharged from the second water distribution channel 23, that is, water is discharged from the bottom. This second water distribution channel 23 is connected to the hand shower head through the hose 232. When rotated 90 degrees counterclockwise, water is discharged from the first water distribution channel 22, that is, water is discharged from the top. This first water distribution channel 22 is connected to the overhead shower head through the rigid pipe 222.

[0041] The above description is merely a preferred embodiment of the present invention, and therefore should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of the patent and the contents of the specification should still fall within the scope of the present invention.
