[0066] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0067] See also Figures 1 to 11 As shown, a water-powered scrubbing shower machine comprises a shower part 1 and a scrubbing part 2, wherein the shower part 1 is placed above the scrubbing part 2 and a shower head 11 is arranged on the top;

[0068] The bathing part 2 includes a housing 21, a massage device 22 with its end exposed outside the housing 21, and a lifting cylinder 23, a fixing sleeve 24, a water pipe 25, a first commutator 26, a second commutator 27, and a reversing valve 28 arranged in the housing 21, wherein:

[0069] The housing 21 includes an upper housing 212, a lower housing 213 and a shell 211 therebetween. The shell 211 is provided with a longitudinal moving groove 214 for the massage device 22 to move. The shower head 11 is connected to a shower water pipe 12. The other end of the shower water pipe 12 passes through the housing 21 and forms a shower water inlet pipe 121 outside the lower housing 213.

[0070] The massage device 22 includes a water-powered rotating device 221, a rotating massage head 222 and a frame 223. The water-powered rotating device 221 is a three-cylinder star-shaped piston structure and is installed on the frame 223. The water pipe 25 is connected to the water-powered rotating device 221 to make it work, thereby driving the rotating massage head 222 to rotate.

[0071] The fixed sleeve 24 fixes the frame 223 to the middle section of the lifting cylinder 23. The frame 223 divides the lifting cylinder 23 into two parts, the upper and lower parts. Both parts are retractable structures. Each part is composed of a number of sleeves 231 that are nested with each other and whose diameters decrease toward both ends. The fixed sleeve 24 fixes the frame 223 on the sleeve with the largest diameter, and the sleeve with the smallest diameter is connected to the water pipe 25. In order to make the massage device 22 move smoothly, the number of the lifting cylinders 23 is two and they are arranged in parallel. At the same time, two parallel guide columns 29 are fixed in the shell 21, and the frame 223 is slidably connected to the guide columns 29.

[0072] One end of the water pipe 25 is a water inlet pipe 251 connected to the reversing valve 28, and the other end is connected to the water power rotating device 221 through a hose 252. The water pipe 25 connects the reversing valve 28, the lifting cylinder 23, the first reversing device 26, and the second reversing device 27 to each other. When the water in the water pipe 25 flows out through two different outlets of the reversing valve 28, it passes through the first reversing device 26 and the second reversing device 27 to make the lifting cylinder 23 expand and contract in different directions, thereby driving the massage device 22 to move up and down.

[0073] Specifically, Figure 4The water inlet pipe 251 of the water pipe 25 is connected to the water inlet a of the reversing valve 28. The top of the reversing valve 28 is the upper outlet b2 of the reversing valve, and the bottom is the lower outlet b1 of the reversing valve. The tops of the two lifting cylinders 23 are connected to the water pipe 25 respectively, and the first descending inlet c2 and the second descending inlet c2' are connected to the bottom respectively. The first reversing device 26 is provided with a first reversing device closing inlet e1, a first reversing device water inlet e2, a first reversing device opening inlet e3, and a first reversing device water outlet e4. The second reversing device 27 is provided with a second reversing device closing inlet d1, a second reversing device water inlet d2, The second diverter opens the inlet d3 and the second diverter outlet d4, and the connection point between the water pipe 25 and the hose 252 is the outlet f; the water pipe 25 connects the lower outlet b1 of the diverter valve with the first rising inlet c1, the second rising inlet c1′, the second diverter closed inlet d1, the second diverter water inlet d2, and the first diverter open inlet e3, and connects the upper outlet b2 of the diverter valve with the first descending inlet c2, the second descending inlet c2′, the first diverter closed inlet e1, the first diverter water inlet e2, and the second diverter open inlet d3, and connects the second diverter outlet d4 and the first diverter outlet e4 with the outlet f.

[0074] In order to use water flow to complete the reversal, the first commutator 26 and the second commutator 27 have the same structure. Taking the second commutator 27 as an example, it includes a sleeve 271 and a core 272. The core 272 is slidably inserted into the sleeve 271. The sleeve 271 is provided with a first channel 2711 with a larger diameter and a second channel 2712 with a smaller diameter. The part of the core 272 located in the first channel 2711 is divided into a water-isolating ring 2722 and a first limit block 2721 and a second limit block 2723 on both sides of the water-isolating ring 2722. The water-isolating ring 2722 divides the first channel 2711 into two parts to form a first pressure chamber 273 and a second pressure chamber 275. The part of the core 272 located in the second channel 2712 is provided with a neck 2724 to form a water-passing chamber 274 in the second channel 2712.

[0075] In order to manually control the moving direction of the massage device 22, the reversing valve 28 is connected to a control handle 281, which moves up and down to make the water flowing into the reversing valve from the water inlet a flow out from the upper outlet b2 of the reversing valve or the lower outlet b1 of the reversing valve, and the control handle 281 is located outside the shell 21.

[0076] In order to fix the scrubbing shower machine for convenient use, both the upper shell 212 and the lower shell 213 are provided with a fixing plate 3 for fixing.

[0077] The operating principle of the present invention is: connect the shower water inlet pipe 121 and the water inlet pipe 251 to the external water source respectively, and then the water flows from the water inlet a of the reversing valve into the reversing valve 28;

[0078] When it is necessary to move the massage device 22 upward, Fig. 9 As shown, the control handle 281 is lifted upward, and the water inlet a of the reversing valve is connected to the lower outlet b1 of the reversing valve. After the water flows out of the lower outlet b1 of the reversing valve, a part of the water flows into the second reversing device closed inlet d1 and fills the second pressure chamber 275. Figure 8 As shown, at this time, the core 272 in the second commutator 27 is lifted upward, so that the second commutator water inlet d2 and the second commutator water outlet d4 cannot be connected through the water passage chamber 274, and the second commutator 27 is in a closed state; similarly, a part of the water flow flows into the first commutator opening inlet e3 of the first commutator 26, so that the first commutator 26 is in an open state, and the first commutator water inlet e2 is connected to the first commutator water outlet e4; another part of the water flow flows into the first rising inlet c1 and the second rising inlet c1′, so that the lower half of the lifting cylinder 23 generates water pressure, pushing the frame 223 upward, thereby moving the massage device 22 upward, and at the same time, the water in the upper half of the lifting cylinder 23 is squeezed out, flows out from the first descending inlet c2 and the second descending inlet c2′, and flows into the first commutator 26 through the first commutator water inlet e2, flows out from the first commutator water outlet e4, and finally flows into the hydrodynamic rotating device 221 through the water outlet f, causing it to do work, driving the rotating massage head 222 to rotate, and completing the bathing function.

[0079] Similarly, when the massage device 22 needs to be moved downward, Fig.10 As shown, the control handle 281 is pressed downward, and the water inlet a of the reversing valve is connected to the upper outlet b2 of the reversing valve. After the water flows out from the upper outlet b2 of the reversing valve, a part of the water flows into the closed inlet e1 of the first reversing device, so that the water inlet e2 of the first reversing device and the water outlet e4 of the first reversing device cannot be connected, and the first reversing device 26 is in a closed state; similarly, a part of the water flows into the second reversing device open inlet d3 of the second reversing device 26, as shown in FIG. Figure 7 , so that the second commutator 27 is in an open state, and the second commutator water inlet d2 is connected to the second commutator water outlet d4; the other part flows into the first descending inlet c2 and the second descending inlet c2′, so that the upper part of the lifting cylinder 23 generates water pressure, pushing the frame 223 downward, thereby moving the massage device 22 downward, squeezing out the water in the lower part of the lifting cylinder 23, and flowing out through the first ascending inlet c1 and the second ascending inlet c1′, and flowing into the second commutator 27 through the second commutator water inlet d2, and flowing out from the second commutator water outlet d4, and finally flowing into the hydrodynamic rotating device 221 through the water outlet f, causing it to do work, driving the rotating massage head 222 to rotate, and completing the bathing function.

[0080] The hydrodynamic rotating device 221 can rotate when water is flowing, and its structure can be an impeller structure or a piston structure. In this embodiment, the hydrodynamic rotating device 221 uses the structure of a handheld hydrodynamic cleaner with application number CN201910123711.0 as a basis. Fig.11 As shown, the three piston heads 2214 are rotatably connected to the crankshaft 2212 through the connecting rod 2215 and placed in the water-powered cylinder 2211. After the hose 252 is connected to it, it flows into the water-powered cylinder 2211 through the water distributor 2213, so that the piston heads 2214 are compressed. Then the connecting rod 2215 drives the crankshaft 2212 to rotate. Under the action of the water distributor 2213, the water flow pushes each piston head 2214 to move in turn, so that the crankshaft 2212 rotates continuously, and the rotating massage head 222 connected to it rotates, so as to achieve the purpose of scrubbing.

[0081] The key point of the design of the present invention is to add a scrubbing function on the basis of a shower function, and fully utilize the water flow as a driving source to drive the rotation and movement of the rotating massage head, so that a larger range of the body can be scrubbed, thereby improving the comfort and efficiency of bathing. There is no need to connect to electricity, thus avoiding the risk of leakage and greatly improving safety.

[0082] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
