[0016] As can be seen from the above description of the present invention and its preferred embodiments, compared with the prior art, the technical solution of the present invention and its preferred embodiments have the following beneficial effects due to the adoption of the following technical means:

[0017] 1. In Scheme 1 and its preferred embodiments, a back spray includes a water outlet body. The water outlet body is provided with a first water passage cavity, a second water passage cavity, a first water passage hole, a second water passage hole, a through hole, and a water outlet hole. The first water passage cavity and the second water passage cavity are arranged along a first direction and isolated from each other to prevent water from flowing through. The first water passage cavity, the through hole, the first water passage hole, and the water outlet hole are arranged along the first direction and connected in sequence. Since the first water passage cavity is farther from the water outlet hole than the second water passage cavity, the through hole is needed to guide the water to the water outlet hole. The second water passage cavity, the second water passage hole, and the water outlet hole are arranged along the first direction and connected in sequence, so that water from both the first water passage cavity and the water outlet hole flows out from the water outlet hole, simplifying the structure and not affecting the water outlet area. Furthermore, since there is no corresponding connection between the through hole and the first water passage hole and the second water passage hole, water flow through will not occur, thus achieving stable water output. The water output patterns of the second water passage cavity and the first water passage cavity are different, thus achieving different water output patterns from the same hole, simplifying the structure and increasing the number of water output patterns. The first and second water passages are arranged in a vertical direction perpendicular to the first direction, reducing the length of the product in the first direction. Furthermore, the water passages are arranged in the first direction, making the arrangement of the water passages more compact and further reducing the length of the product in the first direction.

[0018] 2. In Scheme 2 and its preferred embodiments, the water outlet body includes an outer shell and a water passage plate. The outer shell is provided with a through hole and a water outlet hole. The water passage plate is installed on the outer shell and is provided with a partition rib. The partition rib is adapted to extend into the through hole and divide the through hole into a first water passage hole and a second water passage hole. By manufacturing separately, it is convenient to form the first water passage hole and the second water passage hole arranged in the vertical direction.

[0019] 3. In Scheme 3 and its preferred embodiment, the first water passage extends obliquely upward along the first direction, causing water at the first water passage to flow out obliquely upward. The second water passage extends obliquely downward along the first direction, causing water at the second water passage to flow out obliquely downward. The upper and lower walls of the water outlet gradually decrease in size along the first direction, so that the direction of water at the first and second water passages is not easily blocked by the walls of the water outlet. Thus, when water flows out of the water outlet, it still flows obliquely upward (when water flows out of the first water passage) or obliquely downward (when water flows out of the second water passage). Based on Scheme 2 above, in order to realize the water channel design with corresponding oblique water flow, the water outlet body is manufactured separately, which can realize the extension direction of the corresponding first and second water passages and the size change of the water outlet, which is convenient for processing.

[0020] 4. In Scheme 4 and its preferred embodiments, the thickness of the upper and lower hole walls and / or the partition ribs of the through hole gradually decreases along the first direction. Through the change in the size of the through hole and / or the partition ribs, a first water through hole extending upward and inclined along the first direction and a second water through hole extending downward and inclined along the first direction are formed between the through hole and the partition ribs, which helps to form the upward / downward inclined water pattern.

[0021] 5. In Scheme 5 and its preferred embodiments, the second water passage cavity is provided with a water passage cavity and a water inlet channel. The water inlet channel connects the water passage cavity and the second water passage hole. Water enters through the water in a direction perpendicular to the first direction and exits through the water in the first direction, so as to avoid generating rotating water flow that affects the water pattern and the water outlet angle.

[0022] 6. In Scheme Six and its preferred embodiments, the outer shell is provided with an installation cavity, the installation cavity has a first surface and a second surface arranged opposite to each other, and the opening of the through hole away from the water outlet is located on the second surface; the water passage plate is provided with a plate body, a sealing part and a partition rib protruding from the sealing part, the plate body and the sealing part are placed in the installation cavity, the plate body and the first surface enclose to form a first water passage cavity, the plate body and the sealing part and the second surface enclose to form a second water passage cavity, and the water passage hole penetrates the plate body and the sealing part, thereby realizing the setting of the first water passage cavity and the second water passage cavity; the sealing part covers the through hole and seals against the second surface to prevent water at the second water passage cavity from entering the first water passage hole and water at the water passage hole from entering the second water passage cavity.

[0023] 7. In Scheme 7 and its preferred embodiments, a switching component is further included. The first water passage chamber is provided with a first water outlet, and the second water passage chamber is provided with a second water outlet. The switching component is installed on the water outlet body and is provided with a blocking part. The switching component is adapted to move relative to the water outlet body so that the blocking part changes the water passage area of ​​the first and second water outlets, thereby changing the water passage volume of the first and second water passage chambers and realizing flow regulation. Based on Scheme 3, the water outlet angle can be adjusted by adjusting the water flow, which has higher reliability and lower cost. Different users can adjust different water outlet angles according to their height or body part requirements to meet user needs and is suitable for more people.

[0024] 8. In Scheme 8 and its preferred embodiments, the water outlet body is provided with a rotating hole with a circular cross-section. The first and second water outlets are opened on the wall of the rotating hole. The sealing part is located inside the rotating hole. The switching component is adapted to rotate relative to the water outlet body so that the sealing part covers or opens the first and second water outlets. Switching is achieved by rotation, which is easy to achieve stepless adjustment. The circumferential surface fit makes it easy to achieve a hard seal, and the low friction makes it easy to rotate. The sealing part is adapted to completely cover the first and second water outlets, and is also adapted to simultaneously open parts of the first and second water outlets. This allows for water to pass through the first water passage chamber, the second water passage chamber, and a mixed water passage through the first and second water passage chambers. Combined with stepless adjustment, the strength or weakness of the first water passage chamber can be increased or decreased, resulting in a richer water outlet pattern.

[0025] 9. In Scheme 9 and its preferred embodiments, a push button is also included. One of the push button and the switching component is provided with a strip hole, and the other is provided with an abutment post extending into the strip hole. The abutment post is adapted to slide with the strip hole and abut against the wall of the strip hole for transmission. The switching component is adapted to rotate and connect with the water outlet body. It is easier to operate with one hand by pushing with the push button. Furthermore, due to the strip hole, the abutment post and the strip hole can be prevented from jamming during the rotation of the switching component, ensuring smooth rotation.

[0026] 10. In Scheme 10 and its preferred embodiments, the water outlet body is further provided with a third water passage cavity extending in a vertical direction perpendicular to the first direction. The third water passage cavity is suitable for connecting to the top spray to increase the water outlet pattern. Attached Figure Description

[0047] refer to Figures 1-12 A back spray is suitable for washing the back. The back spray includes a water outlet body 1, a switching component 2, and a push button 3.

[0048] The water outlet body 1 includes an outer shell 11 and a water passage plate 12.

[0049] refer to Figure 3 , Figure 4 The outer casing 11 is provided with a mounting cavity 111, a through hole 112, a water outlet 113 and a rotating hole 114. The mounting cavity 111 is provided with a first surface 1111 and a second surface 1112 arranged opposite to each other. The first surface 1111 and the second surface 1112 are perpendicular to the first direction 4. The mounting cavity 111 is also provided with a first water outlet 1113 and a second water outlet 1114.

[0050] The through hole 112 extends along the first direction 4 and connects the water outlet 113 and the mounting cavity 111. The opening of the through hole 112 away from the water outlet 113 is located on the second surface 1112. The dimensions of the upper and lower walls of the through hole 112 gradually decrease along the first direction 4 and towards the water outlet 113. The water outlet 113 extends along the first direction 4, and the dimensions of the upper and lower walls of the water outlet 113 gradually decrease along the first direction 4. The first direction 4 is the water outlet direction, typically facing the user.

[0051] refer to Figure 8 , Figure 9 The rotating hole 114 has a circular cross-section and is connected to the mounting cavity 111. The first water outlet 1113 and the second water outlet 1114 are opened on the hole wall of the rotating hole 114.

[0052] refer to Figure 9 The outer casing 11 is also provided with a third water passage cavity 115 extending along a vertical direction 5 perpendicular to the first direction 4, the third water passage cavity 115 being used to communicate with the top spray.

[0053] refer to Figure 4 , Figure 11 The water-passing plate 12 is installed on the outer casing 11 and is provided with a plate body 121, a sealing part 122 and a partition rib 123 protruding from the sealing part 122.

[0054] The thickness of the dividing rib 123 (parallel to the vertical direction 5) gradually decreases along the first direction 4. The dividing rib 123 is adapted to extend into the through hole 112 and divide the through hole 112 into a first water passage hole 1121 and a second water passage hole 1122 arranged along the vertical direction 5 perpendicular to the first direction 4, with the dividing rib 123 directly opposite the center of the outlet hole 113. The first water passage hole 1121 extends obliquely upward along the first direction 4, and the second water passage hole 1122 extends obliquely downward along the first direction 4. The first water passage hole 1121 is located below the second water passage hole 1122. In this embodiment, the oblique direction of the first water passage hole 1121 and the second water passage hole 1122 is caused by the combined thickness of the dividing rib 123 and the dimensions of the upper and lower walls of the outlet hole 113. In other embodiments, it may be caused solely by the dimensions of the upper and lower walls of the outlet hole 113 or the thickness of the dividing rib 123.

[0055] refer to Figure 4 The plate 121 and the sealing part 122 are placed in the mounting cavity 111. The plate 121 and the first surface 1111 enclose a first water passage cavity 13, and the plate 121 and the sealing part 122 and the second surface 1112 enclose a second water passage cavity 14, so that the first water passage cavity 13 and the second water passage cavity 14 are arranged along the first direction 4 and isolated from each other. The first water passage cavity 13 is farther away from the water outlet 113 than the second water passage cavity 14. The first water outlet 1113 is the water inlet of the first water passage cavity 13, and the second water outlet 1114 is the water inlet of the second water passage cavity 14. Specifically, plate 121 is spaced apart from the first surface 1111, and the plate 121 and the first surface 1111 enclose a first water passage cavity 13; plate 121 is spaced apart from the second surface 1112, and the plate 121 and the second surface 1112 enclose a water passage cavity 141; sealing part 122 covers the through hole 112 and seals against the second surface 1112, and the sealing part 122 is provided with a water inlet channel 142, which connects to the water passage cavity 141. 1. The second water passage 1122 and the water inlet channel 142 extend in a direction perpendicular to the first direction 4 and penetrate the sealing part 122 in the direction of extension to form the water inlet end of the water inlet channel 142 on the side of the sealing part 122, so that water enters the water inlet channel 142 in a direction perpendicular to the first direction 4. The water outlet end of the water inlet channel 142 is located on the top surface of the sealing part 122 and communicates with the second water passage 1122, so that water exits the water inlet channel 142 in the first direction 4. The water passage cavity 141 and the water inlet channel 142 together enclose to form the second water passage cavity 14.

[0056] The water-passing plate 12 is also provided with a water-passing hole 124, which penetrates the plate body 121 and the sealing part 122, and connects the first water-passing cavity 13 and the first water-passing hole 1121. The water inlet channel 142 and the water-passing hole 124 are located at the upper and lower ends of the partition rib 123, respectively.

[0057] refer to Figure 4 To facilitate the installation of the water-passing plate 12, the outer casing 11 can be manufactured in separate parts. After the outer casing 11 and the water-passing plate 12 are installed, the first water-passing cavity 13, the water-passing hole 124, the first water-passing hole 1121, and the water-outlet hole 113 are arranged along the first direction 4 and connected in sequence; the second water-passing cavity 14, the second water-passing hole 1122, and the water-outlet hole 113 are arranged along the first direction 4 and connected in sequence, and the water outlet pattern of the second water-passing cavity 14 is different from that of the first water-passing cavity 13. In this embodiment, since the first water-passing hole 1121 extends obliquely upward along the first direction 4, the second water-passing hole 1122 extends obliquely downward along the first direction 4, and the water-passing cross section of the water-outlet hole 113 gradually decreases along the first direction 4, the first water-passing cavity 13 and the second water-passing cavity 14 are respectively suitable for obliquely upward water outlet and obliquely downward water outlet. In the above, the water outlet patterns of the second water passage chamber 14 and the first water passage chamber 13 are different because of the different water outlet angles. In other embodiments, the different water outlet patterns can also be due to different water outlet shapes, different water outlet intensities, etc.

[0058] refer to Figure 1 , Figure 2 , Figure 8 , Figure 9 The switching element 2 is installed on the water outlet body 1 and is provided with a blocking part 21. The switching element 2 is adapted to move relative to the water outlet body 1 so that the blocking part 21 changes the water passage area of ​​the first water outlet 1113 and the second water outlet 1114. In this embodiment, the blocking part 21 is located inside the rotating hole 114. The switching element 2 is adapted to rotate relative to the water outlet body 1 so that the blocking part 21 covers or opens the first water outlet 1113 and the second water outlet 1114. The blocking part 21 is adapted to completely cover the first water outlet 1113 and the second water outlet 1114, and is also adapted to simultaneously open portions of the first water outlet 1113 and the second water outlet 1114.

[0059] refer to Figure 1 , Figure 2 , Figure 12 The push button 3 is slidably connected to the outer casing 11 along the vertical direction 5. One of the push button 3 and the switching component 2 is provided with a strip-shaped hole 22, and the other is provided with an abutting post 31 extending into the strip-shaped hole 22. The abutting post 31 is adapted to slide and engage with the strip-shaped hole 22 and abut against the hole wall for transmission. The switching component 2 is adapted to rotately connect to the water outlet body 1. In this embodiment, the push button 3 is provided with an abutting post 31 extending along the first direction 4, and the switching component 2 is provided with a strip-shaped hole 22.

[0060] When using, refer to Figure 9By pushing the switch 2 with the push button 3, the spray angle can be infinitely adjusted up and down. When the blocking part 21 completely blocks the first water outlet 1113, water enters through the second water outlet 1114, and the second water passage chamber 14, the second water passage hole 1122, and the water outlet hole 113 are connected in sequence, and water is discharged at an angle downwards. (Reference) Figure 8 When the sealing part 21 completely blocks the second water outlet 1114, water enters the first water outlet 1113, and the first water passage cavity 13, water passage hole 124, first water passage hole 1121, and water outlet hole 113 are connected in sequence, and water flows out at an upward angle. When the sealing part 21 simultaneously opens portions of the first water outlet 1113 and the second water outlet 1114, water enters both the first water outlet 1113 and the second water outlet 1114 simultaneously, and the direction of water flow (upward or downward) is determined by the water inlet area of ​​the first water outlet 1113 and the second water outlet 1114. If the water inlet areas of the two water outlets are the same, the water flows out nearly horizontally. In this embodiment, refer to... Figure 10 The third water passage 115 is not controlled by the switching element 2, but in other embodiments, it may be controlled by the switching element 2.

[0061] Compared with the prior art, this embodiment has the following beneficial effects:

[0062] In one exemplary embodiment, a back spray includes a water outlet body 1. The water outlet body 1 is provided with a first water passage cavity 13, a second water passage cavity 14, a first water passage hole 1121, a second water passage hole 1122, a water inlet hole 124, and a water outlet hole 113. The first water passage cavity 13 and the second water passage cavity 14 are arranged along a first direction 4 and isolated from each other to prevent water from flowing between them. The first water passage cavity 13, the water inlet hole 124, the first water passage hole 1121, and the water outlet hole 113 are arranged along the first direction 4 and connected in sequence. Since the first water passage cavity 13 is farther away from the water outlet hole 113 than the second water passage cavity 14, the water inlet hole 124 is needed to guide the water to the water outlet hole 113. The second water passage cavity 14, the second water passage hole 1122, and the water outlet hole 113 are arranged along the first direction 4 and connected in sequence, so that water from both the first water passage cavity 13 and the water outlet cavity 14 exits through the water outlet hole 113, simplifying the structure and not affecting the water outlet area. Furthermore, since there is no corresponding connection between the water passage 124 and the first water passage 1121 and the second water passage 1122, water leakage will not occur, thus achieving stable water output. The water output patterns of the second water passage 14 and the first water passage 13 are different, thus achieving different water outputs from the same hole, simplifying the structure and increasing the number of water output patterns. The first water passage 1121 and the second water passage 1122 are arranged along the vertical direction 5 perpendicular to the first direction 4, reducing the length of the product along the first direction 4. Moreover, the arrangement of each water passage along the first direction 4 makes the arrangement of each water passage more compact, further reducing the length of the product along the first direction 4.

[0063] In one exemplary embodiment, the water outlet body 1 includes a housing 11 and a water passage plate 12. The housing 11 is provided with a through hole 112 and a water outlet hole 113. The water passage plate 12 is installed on the housing 11 and is provided with a dividing rib 123. The dividing rib 123 is adapted to extend into the through hole 112 and divide the through hole 112 into a first water passage hole 1121 and a second water passage hole 1122. By manufacturing separately, it is convenient to form the first water passage hole 1121 and the second water passage hole 1122 arranged in the vertical direction 5.

[0064] In one exemplary embodiment, the first water passage 1121 extends obliquely upward along the first direction 4, causing water at the first water passage 1121 to flow out obliquely upward. The second water passage 1122 extends obliquely downward along the first direction 4, causing water at the second water passage 1122 to flow out obliquely downward. The upper and lower walls of the outlet hole 113 gradually decrease along the first direction 4, thereby making it less likely that the direction of water at the first water passage 1121 and the second water passage 1122 will be blocked by the wall of the outlet hole 113. Thus, when water flows out of the outlet hole 113, it is still obliquely upward (when water flows out of the first water passage 1121) or obliquely downward (when water flows out of the second water passage 1122). Based on the above-mentioned second scheme, in order to realize the corresponding oblique water flow channel design, the water outlet body 1 is manufactured separately, which can realize the extension direction of the corresponding first water passage 1121 and second water passage 1122, as well as the size change of the outlet hole 113, which is convenient for processing.

[0065] In one exemplary embodiment, the thickness of the upper and lower walls of the through hole 112 and / or the partition ribs 123 gradually decreases along the first direction 4. Through the size change of the through hole 112 and / or the partition ribs 123, a first water through hole 1121 extending obliquely upward along the first direction 4 and a second water through hole 1122 extending obliquely downward along the first direction 4 are formed between the through hole 112 and the partition ribs 123, which helps to form an upward / downward oblique water pattern.

[0066] In one exemplary embodiment, the second water passage 14 is provided with a water passage 141 and a water inlet channel 142. The water inlet channel 142 connects the water passage 141 and the second water passage hole 1122. Water enters through the water inlet channel 142 in a direction perpendicular to the first direction 4 and exits through the water in the first direction 4, so as to avoid generating rotating water flow that affects the water pattern and the water outlet angle.

[0067] In one exemplary embodiment, the outer casing 11 is provided with a mounting cavity 111, the mounting cavity 111 having a first surface 1111 and a second surface 1112 disposed opposite to each other, and the opening of the through hole 112 away from the water outlet 113 is located on the second surface 1112; the water-passing plate 12 is provided with a plate body 121, a sealing part 122 and a partition rib 123 protruding from the sealing part 122, the plate body 121 and the sealing part 122 are placed in the mounting cavity 111, and the plate body 121 and the first surface 1111 enclose each other to form a shape. A first water passage cavity 13 is formed, and a second water passage cavity 14 is formed by the plate 121, the sealing part 122, and the second surface 1112. A water passage hole 124 penetrates the plate 121 and the sealing part 122, thereby realizing the setting of the first water passage cavity 13 and the second water passage cavity 14. The sealing part 122 covers the through hole 112 and seals against the second surface 1112 to prevent water at the second water passage cavity 14 from entering the first water passage hole 1121 and water at the water passage hole 124 from entering the second water passage cavity 14.

[0068] In one exemplary embodiment, a switching component 2 is further included. A first water passage chamber 13 is provided with a first water outlet 1113, and a second water passage chamber 14 is provided with a second water outlet 1114. The switching component 2 is installed on the water outlet body 1 and is provided with a sealing part 21. The switching component 2 is adapted to move relative to the water outlet body 1, so that the sealing part 21 changes the water passage area of ​​the first water outlet 1113 and the second water outlet 1114, thereby changing the water flow rate of the first water passage chamber 13 and the second water passage chamber 14, achieving flow rate regulation. Based on scheme three, the water outlet angle can be adjusted by adjusting the water flow, resulting in higher reliability and lower cost. Different users can adjust different water outlet angles according to their height or body part requirements, meeting user needs and applicable to a wider range of people.

[0069] In one exemplary embodiment, the water outlet body 1 is provided with a circular rotating hole 114. A first water outlet 1113 and a second water outlet 1114 are formed in the wall of the rotating hole 114. A sealing part 21 is located inside the rotating hole 114. The switching member 2 is adapted to rotate relative to the water outlet body 1, so that the sealing part 21 can cover or open the first water outlet 1113 and the second water outlet 1114. Switching is achieved by rotation, which facilitates stepless adjustment. Furthermore, the circumferential surface fit facilitates a hard seal, and the low friction makes rotation easy. The sealing part 21 is adapted to completely cover the first water outlet 1113 and the second water outlet 1114, and is also adapted to simultaneously open portions of the first water outlet 1113 and the second water outlet 1114. This allows for water to flow through the first water passage chamber 13, the second water passage chamber 14, and a mixed flow of water between the first and second water passage chambers 13 and 14. Combined with stepless adjustment, the strength or weakness of the first water passage chamber 13 can be adjusted, resulting in a richer variety of water outlet patterns.

[0070] In one exemplary embodiment, a push button 3 is also included. One of the push button 3 and the switching member 2 is provided with a strip hole 22, and the other is provided with an abutting post 31 extending into the strip hole 22. The abutting post 31 is adapted to slide with the strip hole 22 and abut against the hole wall of the strip hole 22 for transmission. The switching member 2 is adapted to be rotatably connected to the water outlet body 1 and pushed by the push button 3, making it easier to operate with one hand. Furthermore, due to the strip hole 22, the abutting post 31 can be prevented from jamming with the strip hole 22 during the rotation of the switching member 2, ensuring smooth rotation.

[0071] In one exemplary embodiment, the water outlet body 1 is further provided with a third water passage cavity 115 extending along a vertical direction 5 perpendicular to the first direction 4. The third water passage cavity 115 is adapted to connect to the top spray to increase the water outlet pattern.
