[0046] In response to the problem that the adjustment of both the massage head and the water flow of the shower head requires adjustment in related technologies, which involves many adjustment steps and is cumbersome to operate, this application switches the water flow channel by rotating the adjusting component and adjusts the position of the massage head by rotating the adjusting component. This allows for the adjustment of both the water flow of the shower head and the massage head through the adjusting component, reducing the difficulty of adjustment and making the shower head easier to use.

[0047] The shower head of an embodiment of this application is described below with reference to the accompanying drawings. It should be noted that... Figure 3 , Figure 5 and Figure 7 The text uses solid arrows and dashed lines to illustrate the flow path of water.

[0048] Reference Figures 1 to 5 According to an embodiment of the present invention, a shower head 10 includes a main body 100, an adjusting member 200, and a massage head 300. The main body 100 is provided with a water inlet channel 110 and a receiving groove 120. The water inlet channel 110 communicates with the receiving groove 120 and is used to communicate with an external water source to guide water into the shower head 10. The adjusting member 200 is rotatably connected to the main body 100 and is rotatable relative to the main body 100 to a first position and a second position. The adjusting member 200 covers the receiving groove 120, defining a water passage cavity 190 between the adjusting member 200 and the receiving groove 120. The adjusting member 200 is provided with a first flow channel 210 and a second flow channel 220, which are respectively connected to the water passage cavity 190 and the external space. The first flow channel 210 and the second flow channel 220 are respectively used for the water output of the shower head 10. The minimum inner diameter of the first flow channel 210 is larger than the minimum inner diameter of the second flow channel 220, so that the water output capacity of the first flow channel 210 is greater than that of the second flow channel 220. The massage head 300 is provided with a massage part 310 and a connecting part 320, which are respectively located on opposite sides of the massage head 300. The connecting part 320 is connected to the adjusting member 200, and the adjusting member 200 can drive the massage head 300 to move.

[0049] Among them, reference Figures 1 to 3 When the adjusting member 200 is rotated to the first position, the first flow channel 210 is connected to the water inlet channel 110, and the massage part 310 is located on the side of the outer end face 203 facing the water passage cavity 190. (Refer to...) Figure 4 and Figure 5 When the adjusting member 200 is rotated to the second position, the second flow channel 220 connects with the water inlet channel 110, and the massage part 310 protrudes from the outer end face 203 on the side opposite to the water passage cavity 190. By rotating the adjusting member 200, the water flow rate can be adjusted and the usage state of the massage head 300 can be switched. When the shower head 10 has a large water flow for showering, the massage head 300 is retracted into the shower head 10 in a hidden state, reducing the chance of damage to the massage head 300 and improving the aesthetics of the shower head 10. When the massage head 300 is in use and extended from the shower head 10, the shower head 10 has a smaller water flow to assist in the use of bath products, reducing the chance of bath products being directly rinsed away, and allowing for scrubbing and massage through the massage head 300. The shower head 10 of this embodiment reduces the steps required to adjust the usage state of the massage head 300 and the water flow rate of the shower head 10, lowering the adjustment difficulty and making the shower head 10 easier to use.

[0050] Specifically, the massage head 310 has at least the ability to move relative to the adjustment member 200 in a direction toward or away from the water passage cavity 190. During the movement of the adjustment member 200 from the first position to the second position, the massage head 300 moves relative to the adjustment member 200 in a direction away from the water passage cavity 190, and the massage head 310 gradually protrudes from the side of the outer end face 203 away from the water passage cavity 190. Conversely, during the movement of the adjustment member 200 from the second position to the first position, the massage head 300 moves relative to the adjustment member 200 in a direction toward the water passage cavity 190, the massage head 310 gradually retracts into the shower head 10, and finally resides on the side of the outer end face 203 facing the water passage cavity 190.

[0051] It is understandable that the smaller the inner diameter of the flow channel, the greater the resistance to water flow and the smaller the flow rate. Therefore, the flow rate can be controlled by controlling the minimum inner diameter of the flow channel. Furthermore, by controlling the minimum inner diameter of the second flow channel 220, it is possible to achieve a dripping state when the adjusting component 200 is rotated to the second position.

[0052] In some embodiments, refer to Figure 2 The first flow channel 210 and the second flow channel 220 can be continuous through holes (not shown in the figure) provided on the adjusting member 200. As long as the first flow channel 210 and the second flow channel 220 are separated from each other, one end can be connected to the water inlet channel 110, and the other end can be connected to the outside.

[0053] In some embodiments, refer to Figure 1 , Figure 4 and Figure 5 The adjusting member 200 is provided with a receiving cavity 240. At least a portion of the massage head 300 is located within the receiving cavity 240. The second flow channel 220 includes a first hole 221 and a second hole 222. The first hole 221 connects the receiving groove 120 and the receiving cavity 240, and the second hole 222 connects the receiving cavity 240 and the external space. By connecting the second flow channel 220 with the receiving cavity 240, the adjusting member 200 can be in a second position where the first hole 221 connects with the water inlet channel 110, and the massage head 300 extends beyond the shower head 10. The water outlet position of the shower head 10 corresponds to the position of the massage head 300, facilitating the use of bath products while providing moisture with a smaller water flow. Furthermore, the massage part 310 and the second hole 222 correspond in the extension direction of the second hole 222, so that the water outlet of the shower head 10 and the extension of the massage part 310 share the same opening, further improving the coordination between the massage part 310 and the water outlet, and further enhancing the usage effect. (Refer to...) Figure 13 The massage head 300 may have multiple water passage holes 340 to facilitate water flow out through the second hole 222. (See reference) Figure 13The massage head 300 has a relief hole 350 in the middle to facilitate the connection between the rotating shaft 180 and the rotating hole 295.

[0054] In some embodiments, refer to Figure 1 , Figure 3 and Figure 5 The adjusting member 200 is also provided with a water storage cavity 270, which is separated from the receiving cavity 240. The receiving cavity 240 is located in the middle of the receiving groove 120, and the water storage cavity 270 surrounds the circumferential outer side of the receiving cavity 240. The water storage cavity 270 can act as a buffer for water, making the water output of the shower head 10 more uniform. The receiving cavity 240 is located in the middle of the receiving groove 120, which facilitates the installation of the massage head 300 and allows the massage part 310 to be located in the middle of the receiving groove 120, so as to concentrate the massage position and ensure the massage effect. In some embodiments, the first flow channel 210 and the second flow channel 220 are both connected to the water storage cavity 270. In other embodiments, the first flow channel 210 is connected to the water storage cavity 270, and the second flow channel 220 is connected to the receiving cavity 240.

[0055] Specifically, refer to Figure 2 , Figure 3 , Figure 5 and Figure 8 In the embodiment where the first flow channel 210 communicates with the water storage chamber 270, the first flow channel 210 is defined by a third hole 211, a fourth hole 212, and a fifth hole 213 provided on the adjusting member 200. The adjusting member 200 is also provided with an annular groove 290 communicating with the receiving groove 120. The annular groove 290 surrounds the third hole 211, which extends radially along the rotation center axis of the adjusting member 200 and communicates with the annular groove 290. The fourth hole 212 is located within the annular groove 290 and communicates with the receiving groove 120 and the water storage chamber 270. The fifth hole 213 communicates with the water storage chamber 270 and the outside. The communication between the first flow channel 210 and the water storage chamber 270 ensures that the adjusting member 200 is in the first position so that the shower water has a sufficient spray area when the shower head 10 is in shower mode. The first hole 211 and the third hole 211 are spaced apart along the rotation direction of the adjusting member 200 from the first position to the second position. A pressurized nozzle can also be installed at the fifth hole 213, which can further improve the water output effect during showering.

[0056] It is understandable that the middle part of the receiving groove 120 refers to the center position of the cross-section of the receiving groove 120 taken along the direction perpendicular to the central rotation axis of the adjusting member 200.

[0057] Specifically, refer to Figure 1 , Figure 3 and Figure 8The adjusting component 200 can be composed of an outer cover 201 and an inner cover 202. The outer cover 201 and the inner cover 202 together define the receiving cavity 240 and the water storage cavity 270. The inner cover 202 is located on the side near the bottom wall 130. After the outer cover 201 and the inner cover 202 are assembled with the massage head 300, they are fixedly connected to form the complete adjusting component 200. A handle 280 can be provided on the outer cover of the adjusting component 200 to facilitate the user to drive the adjusting component 200 to rotate.

[0058] Furthermore, refer to Figure 1 , Figures 6 to 8 The adjusting member 200 is also provided with a third flow channel 230, which is connected to the first flow channel 210. The minimum inner diameter of the third flow channel 230 is greater than or equal to the minimum inner diameter of the first flow channel 210, to ensure that the shower head 10 has sufficient water flow when it sprays water through the third flow channel 230. The adjusting member 200 can rotate relative to the main body 100 to a third position. The first, second, and third positions are set sequentially along the rotation direction of the adjusting member 200. When the adjusting member 200 is rotated to the third position, the third flow channel 230 is connected to the water inlet channel 110, and at least a portion of the massage head 300 is located outside the receiving groove 120, so that when the massage head 300 is in use and extends out of the receiving groove 120, the shower head 10 has a large water flow for showering, realizing that the shower head 10 can spray water and massage at the same time. By incorporating a third flow channel 230, the shower head 10 can be selected between a simple shower mode, a bath product scrubbing mode, and a shower-while-massaging mode by rotating the adjusting component 200, thereby enhancing the functionality of the shower head 10 and meeting more usage needs.

[0059] Specifically, the third flow channel 230 can be a continuous through-hole directly connected to the first flow channel 210. Alternatively, refer to... Figure 7 and Figure 8 In an embodiment where the adjusting member 200 is provided with an annular groove, the third flow channel 230 includes a sixth hole 231. The sixth hole 231, the first hole 221, and the third hole 211 are spaced apart along the rotation direction of the adjusting member 200 from the first position to the second position. The third flow channel 230 and the first flow channel 210 may have a common flow passage.

[0060] Reference Figure 1 and Figure 9 A rubber part 800, such as a leather cup, can be installed at the outlet of the water inlet channel 110 for sealing, so as to reduce the possibility of water leakage at the connection when the water inlet channel is connected to the first flow channel 210, the second flow channel or the third flow channel.

[0061] It should be noted that, referring to Figure 2 , Figure 3 , Figure 5 and Figure 8This application does not limit the number of the third hole 211, the fourth hole 212, and the fifth hole 213 in the first flow channel 210, nor does it limit the number of the first hole 221 and the second hole 222 in the second flow channel 220, nor does it limit the number of the sixth hole 231 in the third flow channel 230. The number of each hole can be one or more, and can be adapted to the actual water discharge requirements.

[0062] Reference Figure 3 The adjusting member 200 is rotatably connected to the main body 100 via a hole-shaft fit. The main body 100 includes a bottom wall 130 and a side wall 140, which are connected to each other and define a receiving groove 120. A rotating shaft 180 is provided at the center of the bottom wall 130 of the main body 100, and a rotating hole 295 is provided at the center of the adjusting member 200. The rotating shaft 180 is inserted into the rotating hole 295, and a threaded hole is also provided at the center of the rotating shaft 180. A bolt is threaded into the bolt hole, and the bolt's resistance restricts the relative movement of the adjusting member 200 and the main body 100 in the axial direction of the rotating shaft 180. Furthermore, a bolt sleeve is provided between the rotating shaft 180 and the bolt head, which allows adjustment of the bolt's preload to adjust the force required to drive the adjusting member 200 to rotate relative to the main body 100. The inner wall of the rotating hole 295 and the outer surface of the rotating shaft 180 can be further sealed by using a sealing ring and a gasket to reduce the possibility of water accumulation inside the shower head 10. It is understood that the positions of the rotating shaft 180 and the rotating hole 295 can be interchanged; that is, the rotating hole 295 can be provided on the bottom wall 130 of the main body 100, and the rotating shaft 180 can be provided on the adjusting member 200.

[0063] Reference Figure 3 The movement of the massage head 300 within the receiving groove 120 can be achieved by configuring the connecting part 320 of the massage head 300 as a screw (not shown in the figure). A nut (not shown in the figure) is provided at the end of the bolt threaded into the bolt hole, away from the bottom wall 130, as the bolt head, so that the screw can be threadedly connected to the nut. When the screw and nut rotate relative to each other, the massage head 300 can move relative to the main body in the axial direction of the rotating shaft. (Refer to...) Figure 1 , Figure 3 , Figure 13 and Figure 14One of the massage head 300 and the adjusting member 200 is provided with a guide hole 330 extending axially along the rotating shaft 180, and the other is provided with a guide portion 245 extending axially along the rotating shaft 180. The guide portion 245 is inserted into the guide hole 330. The cooperation between the guide hole 330 and the guide portion 245 allows the adjusting member 200 to drive the massage head 300 to rotate. As it rotates, the massage head 300 can move axially along the rotating shaft 180 to extend or retract the shower head 10. It is understood that the guide hole 330 and the guide portion 245 are located radially outward of the rotating shaft 180.

[0064] To further reduce the size of the shower head 10 and facilitate its use, this application embodiment also provides an improvement. (Refer to...) Figure 1 , Figure 9 , Figure 10 and Figure 11 The main body 100 includes a bottom wall 130, a side wall 140, and a guide portion 150. The bottom wall 130 and the side wall 140 are connected to each other and define a receiving groove 120. The guide portion 150 is connected to the bottom wall 130 and extends along the rotation direction of the adjusting member 200. A guide surface 151 is provided on the side of the guide portion 150 opposite to the bottom wall 130. The distance between the guide surface 151 and the adjusting member 200 gradually decreases along the direction of the adjusting member 200 from the first position to the second position. The connecting portion 320 abuts against the guide surface 151. The adjusting member 200 is also provided with a through hole 250, which connects the receiving cavity 240 and the receiving groove 120. The connecting portion 320 passes through the through hole 250. When the adjusting member 200 rotates, it abuts against the connecting portion 320 through the inner wall of the through hole 250, which can drive the massage head 300 to rotate synchronously. The shower head 10 also includes a first elastic element 400, which is connected to the massage head 300. The first elastic element 400 applies a force toward the bottom wall 130 to the massage head 300 to ensure that the connecting part 320 can maintain contact with the guide surface 151. By setting the guide surface 151 to contact the connecting part 320, when the adjusting member 200 drives the massage head 300 to rotate, the connecting part 320 can move along the inclined direction of the guide surface 151 in the axial direction of the rotating shaft 180, so that the massage part 310 can extend or retract into the shower head 10. In this embodiment, the connecting part 320 can enter the water passage cavity 190 through the through hole 250, effectively utilizing the space in the water passage cavity 190, improving the space utilization rate, and effectively reducing the volume of the main body 100.

[0065] Specifically, the first elastic element 400 can be selected as a conventional elastic element in the art, such as a spring or elastic rubber, and provides elastic force by abutting against the massage head 300. For example, the first elastic element 400 can abut against the massage part 310. In some embodiments, the massage head 300 may include a massage part 310, a base 360, and a connecting part 320. The base 360 ​​is connected to the connecting part 320, and the massage part 310 is connected to the base 360 ​​and protrudes towards the side opposite to the connecting part 320. The first elastic element 400 can abut against the base 360. Alternatively, the first elastic element 400 can be selected as an elastic sleeve. One end of the elastic sleeve is fixed to the massage head 300, and the other end of the elastic sleeve is fixed to the bottom wall 130. The base 360 ​​of the massage head 300 is provided with a water passage hole 340, and the elastic sleeve can pass through the water passage hole 340 for sleeve fixation. The elastic sleeve can be an elastic lasso such as a rubber band.

[0066] In this embodiment, one of the massage head 300 and the adjusting member 200 is provided with a guide hole 330 extending axially along the rotating shaft 180, and the other is provided with a guide portion 245 extending axially along the rotating shaft 180. The adjusting member 200 can drive the massage head 300 to rotate through the guide hole 330 and the guide portion 245, thereby reducing the tangential force on the connecting portion 320 and improving the motion stability of the massage head 300.

[0067] Reference Figure 1 , Figure 10 and Figure 11 A support surface 152 is also provided on the side of the guide portion 150 away from the bottom wall 130. The guide surface 151 and the support surface 152 are connected sequentially along the direction of the adjustment member 200 from the first position to the second position. The distance between the support surface 152 and the adjustment member 200 is 'a', and the maximum distance between the guide surface 151 and the adjustment member 200 is 'b', satisfying that 'a < b'. In the second position, the adjustment member 200's connecting portion 320 abuts against the support surface 152. By providing the support surface 152, stable support can be provided for the connecting portion 320, reducing the probability that the connecting portion 320 will be compressed during massage, thus overcoming the elastic force of the first elastic member 400 and sliding backward along the guide surface 151. This ensures that the shower head 10 can provide a stable massage function and improves the stability of the shower head 10. It is understood that in the embodiment with the third flow channel 230, since the first position, the second position and the third position are arranged sequentially along the rotation direction of the adjusting member 200, when the adjusting member 200 rotates to the third position, the connecting part 320 also abuts against the support surface 152. Therefore, when the adjusting member 200 is in the third position, the support surface 152 can also provide stable support for the massage head 300.

[0068] Reference Figure 10 and Figure 11Furthermore, the main body 100 is also provided with a limiting part 160, which is connected to the bottom wall 130. The limiting part 160 and the guide part 150 are connected sequentially along the direction in which the adjusting member 200 rotates from the first position to the second position. The distance between the end face of the limiting part 160 away from the bottom wall 130 and the adjusting member 200 is c, and the maximum distance between the guide surface 151 and the adjusting member 200 is b, satisfying: c < b. After the connecting part 320 moves along the guide surface 151 until the massage part 310 retracts into the shower head 10, the connecting part 320 abuts against the limiting part 160. The limiting part 160 restricts the movement of the connecting part 320 along the rotation direction of the adjusting member 200, thereby restricting the continued rotation of the adjusting member 200 and preventing the adjusting member 200 from over-rotating during use. This ensures that the adjusting member 200 stops after rotating to the first position, improving the positioning accuracy of the adjusting member 200 when rotating to the first position and further facilitating the use of the shower head 10.

[0069] To reduce the difficulty of sliding between the connecting part 320 and the guide surface 151, this application also provides an improvement. (Refer to...) Figure 1 , Figure 7 , Figure 10 and Figure 11 The end of the connecting portion 320 facing away from the massage portion 310 is provided with a curved surface 311, which abuts against the guide surface 151. The curved surface 311 reduces the frictional force when the connecting portion 320 slides against the guide surface 151, and also reduces the resistance tangential to the direction of movement experienced by the connecting portion 320, making the movement of the connecting portion 320 smoother and reducing the difficulty for the rotating adjustment member 200 to drive the massage head 300 to move.

[0070] As an improvement to the above scheme, referring to Figure 1 , Figure 3 , Figure 8 and Figure 9 The main body 100 also includes a fixing part 170, which is connected to the bottom wall 130. The adjusting member 200 has multiple limiting grooves 260 on the side facing the bottom wall 130, with each limiting groove 260 spaced apart along the rotation direction of the adjusting member 200. The shower head 10 also includes a second elastic member 500, one end of which is connected to the fixing part 170, and the other end of which is located within the limiting groove 260. The second elastic member 500 can move from one limiting groove 260 to another as the adjusting member 200 rotates. Through the cooperation of the second elastic member 500 and the limiting groove 260, the adjusting member 200 can have a certain tactile feedback when rotating, indicating to the user how much angle it has rotated or whether the rotation is complete, thus improving the user experience of the shower head 10.

[0071] Specifically, when the adjusting member 200 is in the first position, the second elastic member 500 is located within the first limiting groove 260. When the adjusting member 200 moves to the second position, the second elastic member 500 follows the rotation of the adjusting member 200 and moves into the second limiting groove 260. When the adjusting member 200 moves to the third position, the second elastic member 500 follows the rotation of the adjusting member 200 and moves into the third limiting groove 260. The distance between the three limiting grooves 260 is the same as the spacing between the first, second, and third positions in the rotation direction of the adjusting member 200, so as to accurately indicate to the user that the adjusting member 200 has been rotated into position.

[0072] The second elastic element 500 can be a conventional ball screw or a spring and bolt assembly. When a ball screw is selected, it can be fixedly connected to the inner wall or inserted into a hole provided on the inner wall. When a spring and bolt assembly is selected, a portion of the spring and bolt are located within the hole provided on the inner wall, with one end of the spring abutting against the inner surface of the hole and the other end abutting against one end of the bolt, and the other end of the bolt abutting against the adjusting element 200.

[0073] Reference Figure 4 , Figure 5 and Figure 12 In an embodiment where the connecting portion 320 passes through the through hole 250 and the second flow channel 220 communicates with the receiving cavity 240, since the through hole 250 communicates with the receiving cavity 240, it is necessary to seal the through hole 250 to reduce the possibility of leakage. To solve the above problem, this application also provides an embodiment in which the through hole 250 includes a first hole segment 251 and a second hole segment 252 connected to each other. The inner diameter of the first hole segment 251 is larger than the inner diameter of the second hole segment 252. The shower head 10 also includes a sealing member 600 and a limiting member 700. The sealing member 600 is sleeved on the connecting portion 320 and is located inside the first hole segment 251. The limiting member 700 is fixed to the outer surface of the adjusting member 200 near the bottom wall 130. The limiting member 700 at least covers a portion of the first hole segment 251 and is used to abut against the sealing member 600. By cooperating with the limiting member 700 and the sealing member 600, the gap between the connecting part 320 and the through hole 250 can be sealed, and the movement of the connecting part 320 within the through hole 250 can be ensured, reducing the chance of water leakage.

[0074] Reference Figure 5 and Figure 9The main body 100 is provided with an opening 121, which connects to the receiving groove 120. The adjusting member 200 covers the opening 121. In some embodiments, the outer end face 203 is flush with the opening 121. When the adjusting member 200 is in the second position, the massage part 310 protrudes from the side of the outer end face 203 away from the water passage cavity 190 to ensure that the massage part 310 can contact the user for massage. In some embodiments, the outer end face 203 is located on the side of the opening 121 away from the water passage cavity 190. When the adjusting member 200 is in the second position, the massage part 310 protrudes from the side of the outer end face 203 away from the water passage cavity 190 to ensure that the massage part 310 can contact the user for massage. In some embodiments, the outer end face 203 is located on the side of the opening 121 facing the water passage cavity 190. When the adjusting member 200 is in the second position, the massage part 310 protrudes from the side of the opening 121 away from the water passage cavity 190 to ensure that the massage part 310 can contact the user for massage.
