Description

Technical Field

[0001] The present invention relates to the technical field of bathroom shower heads, and more particularly to a pressure rotary shower head. Background Art

[0002] As people's living standards improve, the requirements for the quality and functions of shower heads are also increasing. At present, most ordinary shower heads on the market can only adjust the shower water spray and size, and have a single function. A small number of ordinary shower heads with massage functions only stimulate the skin's senses through intermittent water flow, and the actual massage effect is not ideal, and it cannot meet the requirements of massage to relieve fatigue.

[0003] Moreover, families with pets have higher requirements for the massage function of shower heads. Ordinary shower heads with massage functions cannot meet the needs of rubbing and massaging pets' fur only through changes in water flow.

[0004] At the same time, showers used in the industrial livestock farming industry need to be equipped with objects such as scratchers to "massage" the livestock during the showering process. Currently, showers used in this industry can only simply shower livestock, clean feces, etc., and cannot effectively massage livestock to relieve itching.

[0005] Some other shower heads with massage functions use motors to drive the rotors to rotate, thereby driving the massage heads to rotate, thereby achieving better massage effects. However, this type of shower head uses motors to drive the rotors, which has strict requirements on the sealing and waterproofing of the shower head, and its internal structure is too complicated, and the manufacturing and use costs are high, which is not conducive to its promotion and use.

[0006] Therefore, it is necessary to improve the existing shower head to increase its massage function and effect, simplify its internal structure, and reduce the production and use costs. Summary of the invention

[0007] In summary, the purpose of the present invention is to solve the technical deficiencies of existing ordinary bath showers, such as single function, poor massage effect or no massage function, overly complex internal structure and high production and use costs, and to provide a pressure rotary shower with a simple structure and good massage effect.

[0008] To achieve the above object, the present invention adopts the following technical solutions:

[0009] A pressure rotary shower head includes a shower head housing, a separation ring is arranged in the cavity of the shower head housing, a rotor is rotatably arranged in the separation ring and matches the inner wall of the separation ring, a cover is arranged in the cavity of the shower head housing for sealing the rotor in the separation ring, a nozzle is arranged above the cover and matches the cavity opening of the shower head housing, and a plurality of massage heads for massage and nozzles for water discharge are arranged on the nozzle head. The nozzle head is coaxially fixedly connected with the rotor, a water storage cavity is formed between the bottom surface of the nozzle head and the top surface of the cover, and the water storage cavity is connected to the external space through the nozzle. More than one arc-shaped protruding section is arranged on the separation ring, and a crescent-shaped water-spraying cavity is formed between each arc-shaped protruding section and the side wall of the rotor, a water-spraying port for water flow to enter is arranged on the separation ring at a position corresponding to the front end of the water-spraying cavity, and a drain port for water flow to discharge is arranged on the cover at a position corresponding to the rear end of the water-spraying cavity, and the water-spraying cavity is connected to the water storage cavity through the drain port. The rotor is movably provided with more than two blades elastically abutting against the inner wall of the separation ring.

[0010] The cavity of the shower housing includes an outer wall surrounding the outer side of the separation ring, and the outer periphery of the cover is sealed against the inner side of the outer wall. A water inlet cavity for water inlet is formed between the outer wall and the separation ring, and the water inlet cavity is connected to the water ejection cavity through the water ejection port, and at least one water inlet for water flow to enter the water inlet cavity is opened on the outer wall.

[0011] The rotor is rotatably connected to the shower housing via a bearing.

[0012] The middle part of the sealing cover is provided with an escape position for connecting the rotor with the spray head.

[0013] A self-lubricating sleeve with a sealing function is movably nested between the avoidance position and the rotor or the nozzle.

[0014] The nozzle is made of skin-friendly material, and a fixing plate is embedded in the nozzle to support and shape the nozzle.

[0015] A circle of outer edge sealing edge for sealing is vertically extended from the bottom edge of the nozzle.

[0016] The rotor is provided with blade receiving grooves having the same number as the blades, and the blades are movably arranged in the blade receiving grooves respectively. Each blade receiving groove is provided with at least one return spring for elastically driving the blade to abut against the inner wall of the separation ring.

[0017] The rotor is provided with more than two inwardly recessed weight-reducing cavities.

[0018] A connecting bone position is formed between two adjacent weight-reducing cavities, and the blades are movably arranged on the connecting bone position.

[0019] The beneficial effects of the present invention are as follows: the water flow in the shower housing enters the water jet cavity under the cover through the water jet port corresponding to the front end of the crescent-shaped water jet cavity and arranged on the separation ring, and enters the water storage cavity on the cover through the water outlet corresponding to the end of the crescent-shaped water jet cavity and arranged on the cover. The water flow entering the water storage cavity is finally sprayed outward through the nozzle arranged on the nozzle, forming a complete water path to realize the function of spraying and bathing of the present invention. The water flow in the water jet cavity flows from one end of the water jet port to one end of the water outlet to impact the blades arranged on the rotor to drive the rotor to rotate, and then drives the nozzle coaxially fixedly connected to the rotor to rotate through the rotor, and realizes the functions of kneading, massaging, anti-itching and fatigue relief of the present invention through the massage head arranged on the nozzle, with a simple structure and good massage effect.

[0020] At the same time, the blades on the rotor of the present invention automatically elastically abut against the inner wall of the separation ring, and automatically expand and contract as the curvature of the inner wall of the separation ring changes. Since the separation ring is provided with an arc-shaped protruding section, the areas of the blades in the arc-shaped protruding section exposed to the outside of the rotor side wall are different, and different force-bearing areas are formed between the blades to block the water flow entering the water-jetting chamber. The water flow in the water-jetting chamber flows out of the end of the water-jetting port from the end of the water-jetting port to impact the blades. According to the pressure formula F=PS, under the condition of consistent water flow pressure P, the blade with a larger protruding area S has a greater pressure F impacted by the water flow. Therefore, the water flow can drive the rotor to rotate continuously under the action of the pressure difference between the blades, forming a water pressure power source for driving the nozzle to rotate. Compared with the existing shower head that uses a motor to drive the rotor to rotate to achieve a massage function, the motor-free device of the present invention only uses the water flow pressure to drive the nozzle to rotate, does not need to be connected to electricity, has a lower requirement for sealing and waterproofing inside the nozzle, effectively simplifies the internal structure of the shower head, reduces the production and use costs of the present invention, and is conducive to popularization and use.

[0021] In addition, the spray head of the present invention is coaxially linked with the rotor, so the water flow sprayed from the nozzle on the spray head is sprayed in a rotating manner, the water output force is strong, and the spray bathing effect is better. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The structure of the present invention is further described below in conjunction with the accompanying drawings and preferred specific embodiments of the present invention. This embodiment is only a preferred implementation of the present invention and cannot be understood as limiting the present invention.

[0036] Reference Figures 1 to 3As shown, the present invention: a pressure rotary shower head, comprises a shower head housing 1, which is composed of a handle 11 with a hollow cylindrical structure at the end and a head 12 with a groove-shaped cavity structure at the head end. The head 12 specifically comprises a bottom plate with a circular structure (not shown in the figure) and an outer wall 13 integrally connected to the bottom plate and vertically surrounding the edge of the bottom plate, and the bottom plate and the outer wall 13 together form the groove-shaped cavity structure of the head 12. The head end of the hollow handle 11 is integrally fixedly connected to the outer wall 13 of the head 12, and a water inlet 131 is provided on the outer wall 13 at the connection between the two, and is used for water in a bathing device such as a water heater to enter the groove-shaped cavity of the shower head 12. The end of the handle 11 is threadedly fixedly connected to the water outlet pipe of the bathing device, and the head 12 of the shower head of the present invention is connected to the bathing device such as a water heater through the water inlet 131 and the handle 11 with a hollow structure to form a water inlet channel.

[0037] Specifically, a circle of separation rings 14 located inside the outer wall 13 is vertically arranged in the cavity of the head 12 of the circular groove structure of the shower housing 1. The separation ring 14 is integrally connected to the bottom plate of the head 12, close to the outer wall 13, and the height of the separation ring 14 needs to be less than the height of the outer wall 13. A pin 17 integrally connected to the bottom plate of the head 12 is also vertically arranged at the center of the bottom plate of the head 12 of the shower housing 1. A bearing 2 is fixedly clamped in the gap on the pin 17. A rotor 3 matching the inner wall of the separation ring 14 is fixedly clamped in the gap on the outer ring of the bearing 2. The rotor 3 can rotate freely with the bearing 2 on the inner side of the separation ring 14.

[0038] It should be noted that, refer to Figure 7 As shown, the “matching” mentioned here means that the smallest part of the inner diameter of the separation ring 14 is movably connected to the side wall of the rotor 3 to ensure that the rotor 3 can rotate freely within the inner wall of the separation ring 14.

[0039] It should also be noted that, referring to Figure 2 As shown, the rotor 3, the bearing 2 and the pin 17 are on the same axis to prevent the rotor 3 from deflecting during rotation and affecting the normal use of the present invention. After the rotor 3 is rotatably connected to the shower head 12 through the bearing 2, the height of its upper surface preferably does not exceed the height of the separation ring 14.

[0040] Specifically, a cover 5 is matched in the cavity of the head 12 of the shower housing 1 for sealing the rotor 3 in the separation ring 14. The cover 5 is a disc-shaped structure matching the inner side of the outer wall 13 and is threadedly fixedly connected to the separation ring 14. After being fixed, the outer periphery of the cover 5 is sealed against the inner side of the outer wall 13, and the bottom of the cover 5 is sealed against the top of the separation ring 14. It should be noted that after the cover 5 is fixedly connected to the separation ring 14, a certain space is left between its top surface and the top opening of the outer wall 13, so that the cavity of the head 12 of the shower housing 1 is divided into two parts, upper and lower, by the cover 5. A nozzle 7 is movably provided above the cover 5, which matches the opening of the cavity of the head 12 of the circular groove structure of the shower housing 1 and is used to seal the head 12. The outer periphery of the nozzle 7 is movably sealed against the upper opening position of the inner side of the outer wall 13. The nozzle 7 is coaxially fixedly connected to the rotor 3 , and a plurality of massage heads 71 ​​for massage and nozzles 72 for water discharge are arranged on the top surface of the nozzle 7 facing away from the cover 5 , and the bottom surface of the nozzle 7 facing the cover 5 is parallel to the cover 5 .

[0041] Specifically, a water storage chamber 18 located above the cover 5 is formed between the bottom surface of the spray head 7 facing the cover 5 and the top surface of the cover 5 . The water storage chamber 18 is connected to the space outside the shower head through the nozzle 72 on the spray head 7 .

[0042] Specifically, refer to Figure 3 , Figures 7 and 8 As shown, the separation ring 14 in this embodiment is an elliptical ring structure protruding to the left and right sides, and the rotor 3 of the flat cylindrical structure is matched and rotated inside the separation ring 14 of the elliptical ring structure, and the diameter of the rotor 3 matches the short axis length of the inner wall of the separation ring 14. The separation ring of the elliptical ring structure is provided with two arc-shaped protruding sections protruding to the left and right sides respectively, and a crescent-shaped water-jetting cavity 16 is formed between each arc-shaped protruding section and the side wall of the rotor 3. The separation ring 14 is provided with two groups of water-jetting ports 141 corresponding to the front ends of the water-jetting cavities 16 on the left and right sides, respectively, for water to enter the water-jetting cavity 16. The cover 5 is provided with two groups of drainage ports 52 corresponding to the rear ends of the water-jetting cavities 16 on the left and right sides, for water to be discharged from the water-jetting cavity 16 to the water storage cavity 18. The water-jetting cavity 16 is connected to the water storage cavity 18 through the drainage ports 52.

[0043] Specifically, refer to Figures 2 to 4 and Figure 7 As shown, the gap between the outer wall 13 of the head 12 and the separating ring 14 is blocked by the sealing cover 5 to form a water inlet chamber 15 surrounding the water ejection chamber 16. The water inlet chamber 15 is connected to a bathing device such as a water heater through the water inlet 131 and the handle 11. At the same time, the water inlet chamber 15 is connected to the water ejection chamber 16 through two groups of water ejection ports 141. The water ejection chamber 16 is connected to the water storage chamber 18 through two groups of drainage ports 52. The water storage chamber 18 is connected to the external space of the shower head through the nozzle 72 on the nozzle 7.

[0044] Specifically, refer to Figure 2 , Figure 5 to Figure 6 As shown, an extension part 31 of a cylindrical structure for fixing and connecting the nozzle 7 is vertically extended upward at the center of the middle circle of the upper surface of the rotor 3. After the rotor 3 is rotated and connected in the head 12, the top of the extension part 31 exceeds the separation ring 14 but is lower than the outer wall 13. A connecting screw hole 311 for threadedly fixing and connecting the nozzle 7 is provided at the center of the top surface of the extension part 31. Four positioning columns 312 are evenly distributed around the connecting screw hole 311 and extend vertically upward to fix the nozzle 7 to ensure that the nozzle 7 can be coaxially linked with the rotor 3. A circle of sleeve accommodating grooves 313 recessed toward the inner part of the upper surface of the rotor 3 are also provided at the bottom of the outer periphery of the extension part 31. A self-lubricating sleeve 4 with a matching bottom accommodated in the sleeve accommodating groove 313 is fixed in the gap on the outer periphery of the extension part 31, and the upper part of the self-lubricating sleeve 4 is slightly lower than the top surface of the extension part 3 after being fixed.

[0045] Specifically, refer to Figure 1 , Figure 2 , Figures 5 to 7 As shown, in order to reduce the weight of the rotor 3 of the present invention and increase the water storage capacity in the inner chamber of the separation ring 14 to increase the water output of the nozzle 7 of the present invention, eight groups of weight-reducing chambers 35 with fan-shaped groove structures that are recessed relative to the inside of the rotor 3 are arranged radially and correspondingly on the upper and lower surfaces of the rotor 3. A total of eight radially arranged connecting bone positions 36 are formed between the eight groups of upper and lower opposite weight-reducing chambers 35. A blade receiving groove 32 extending vertically along the side wall of the rotor 3 toward the axis of the rotor 3 is respectively provided on each connecting bone position 36. Each blade receiving groove 32 penetrates the upper and lower surfaces of the rotor 3 from top to bottom. A spring retaining groove 321 extending along one of the side walls of the blade retaining groove 32 toward the axis of the rotor 3 is horizontally provided in each blade retaining groove 32, and a return spring 33 is matched in each spring retaining groove 321. A blade 34 with a plate-like structure is movably provided in each blade accommodating groove 32 for blocking the directional flow of water in the water injection cavity 16. The tail end of each blade 34 is movably abutted against the reset spring 33, and the head end of each blade 34 is elastically abutted against the smooth curved inner wall of the separation ring 14 driven by the elastic force of the corresponding reset spring 33.

[0046] Since the diameter of the rotor 3 in this embodiment matches the minor axis length of the elliptical ring-shaped separating ring 14, it should be ensured that when the blade 34 is at the position where the side wall of the rotor 3 is closest to the inner wall of the separating ring 14, the blade 34 can overcome the elastic force of the return spring 33 under the pressure of the inner wall of the separating ring 14 and be completely accommodated in the blade accommodating groove 32, ensuring that the blade 34 will not be stuck on the inner wall of the separating ring 14 and hinder the rotation of the rotor 3. At the same time, it should be ensured that when the blade 34 is at the middle position of the water ejection cavity 16 where the side wall of the rotor 3 is farthest from the separating ring 14, the blade 34 will not be separated from the blade accommodating groove 32 and separated from the rotor 3 under the elastic drive of the return spring 33. The above definition ensures that during the free rotation of the rotor 3 inside the separating ring 14 of the present invention, the blade 34 can be abutted against the inner wall of the separating ring 14 under the elastic drive of the return spring 33 and automatically expand and contract while rotating with the rotor 3, so as to automatically adapt to the curvature change of the inner wall of the separating ring 14, thereby ensuring the smooth rotation of the rotor 3 and improving the reliability of the present invention.

[0047] Specifically, refer to Figure 7 and 8 As shown, a clearance position 51 is provided in the middle of the cover 5 for the extension portion 31 of the rotor 3 to pass upward and connect to the nozzle 7. The diameter of the clearance position 51 matches the outer diameter of the upper portion of the self-lubricating sleeve 4 sleeved on the extension portion 31. Two groups of drain ports 52 are correspondingly arranged on the periphery of the clearance position 51. Each group of drain ports 52 has five drain ports and are arranged in an arc shape to adapt to the crescent-shaped end structure of the water ejection chamber 16. Six connecting through holes 53 for threadedly fixing the cover 5 to the separation ring 14 are evenly distributed on the outer peripheral edge of the cover 5. Correspondingly, six connecting studs 142 (such as 142) used in conjunction with the connecting through holes 53 are provided on the separation ring 14. Figure 4 ).

[0048] It should be noted that the extension portion 31 provided on the rotor 3 in this embodiment is used to fix the nozzle 7. In other embodiments, the extension portion 31 can be provided in the middle position of the bottom surface of the nozzle 7, and the nozzle 7 can be fixedly connected to the upper surface of the rotor 3 through the extension portion 31.

[0049] Reference Figure 1 , Figure 2 , Figure 7 and Figure 8As shown, during the actual assembly, the rotor 3 with the self-lubricating sleeve 4 fixed thereon is firstly connected to the cavity of the separation ring 14 of the head 12 by rotation through the bearing 2, and the blades 34 are elastically abutted against the inner wall of the separation ring 14. Then the cover 5 is matched and placed on the separation ring 14 of the head 12, and the connecting through holes 52 and the connecting studs 142 are matched one by one, so that the avoidance position 51 is correspondingly nested on the self-lubricating sleeve 4 on the outer periphery of the extension part 31, and the position is adjusted so that the two groups of drainage ports 52 are correspondingly located at the ends of the crescent-shaped water-spraying cavities 16 on the left and right sides. Then, the cover 5 is horizontally threaded and fixedly connected to the cavity of the head 12 through the six screws 6 through the connecting through holes 53 and the connecting studs 142.

[0050] The cover 5 of the present invention is matched and accommodated in the head 12. After being fixed, its outer peripheral seal abuts against the inner side surface of the outer wall 13. The clearance position 51 in the middle and the extension portion 31 of the rotor 3 are sealed by the self-lubricating sleeve 4, which ensures that the cover 5 can effectively block the water inlet chamber 15 and the water ejection chamber 16 at the lower part. The water flowing into the water inlet chamber 15 through the water inlet 131 can only enter the water ejection chamber 16 through the water ejection port 141 on the separation ring 14, which is conducive to increasing the water pressure in the water inlet chamber 15 and improving the impact force of the water flow entering the water ejection chamber 16. At the same time, the water entering the water ejection chamber 16 can only be concentrated from the water outlet 52 at the other end of the water ejection chamber 16 to enter the water storage chamber 18, which is conducive to increasing the water pressure in the water ejection chamber 16, further improving the impact force of the water flow on the blades 34, making the rotation of the rotor 3 more powerful, and also making the rotation of the rotor 3 more continuous and stable.

[0051] It should be noted that, referring to Figure 7 As shown, in this embodiment, the two groups of water outlets 52 are respectively located at the ends of the crescent-shaped water-jetting chambers 16 on the left and right sides, and the two groups of water outlets 141 are respectively located at the front ends of the crescent-shaped water-jetting chambers 16 on the left and right sides. After the water flows into the water inlet chamber 15 through the handle 11 and the water inlet 131, it enters the water-jetting chambers 16 on the left and right sides through the two groups of water outlets 141. Since the water outlets 141 and the water outlets 52 are respectively located at the front and rear ends of the water-jetting chamber 16 on the same side, after the water flows into the water-jetting chamber 16, it can only flow counterclockwise from one end of the water outlet 141 to one end of the water outlet 52 and impact the blades 34 to drive the rotor 3 to rotate counterclockwise.

[0052] Under the condition of the same water flow pressure P, according to the pressure formula F=PS, when the water flow directional impacts the blade 34 in the same side water jet chamber 16, the larger the area S of the blade 34 extending outward, the greater the water flow pressure F on the blade 34. Therefore, when the water flow impacts the blade 34 in the counterclockwise direction in the water jet chamber 16, the water flow pressure on the blade 34 near the middle end of the water jet chamber 16 is greater than the water flow pressure on the blade 34 near the end of the water jet chamber 16, and a pressure difference is generated between the two, which is conducive to the water flow to flow counterclockwise and impact the blade 34. Therefore, the water flow flowing counterclockwise in the water jet chamber 16 can continuously impact the blade 34 to drive the rotor 3 to rotate continuously in the counterclockwise direction, and drive the nozzle 7 to rotate continuously counterclockwise through the rotor 3.

[0053] Compared with the existing shower head that uses a motor to drive the rotor to rotate and thus drives the massage head to rotate, the present invention does not require external power. It can drive the spray head 7 to rotate continuously only by relying on the pressure of the water flow entering the shower head, and realize the function of rotary massage through the massage head 71 on the spray head 7. There is no need to set up a motor, nor is there any need to seal and waterproof the motor. The internal structure of the shower head of the present invention is effectively simplified, the cost of production and use of the present invention is reduced, and it is conducive to the popularization of the present invention.

[0054] At the same time, the self-lubricating sleeve 4 sleeved on the extension part 31 of the rotor 3 of the present invention and the bearing 2 rotatably arranged between the rotor 3 and the shower housing 1 can effectively reduce the friction between the rotor 3 and the cover 5 and the shower housing 1 when the rotor 3 rotates, so that the rotation of the rotor 3 is smoother. Moreover, the self-lubricating sleeve 4 provided in the present invention can also play a good role in sealing and preventing water leakage, so that the water in the water-jetting chamber 16 under the cover 5 can only flow into the water storage chamber 18 from the drain port 52, which is conducive to increasing the water pressure in the water-jetting chamber 16 and facilitating the water flow to drive the rotor 3 to rotate.

[0055] Moreover, the rotor 3 of the present invention is provided with a plurality of weight-reducing cavities 35, which effectively reduce the weight of the rotor 3 itself, making the rotation of the rotor 3 more flexible. The plurality of weight-reducing cavities 35 provided on the rotor 3 can also increase the water storage capacity in the inner cavity of the separation ring 14, which is beneficial to increase the water output of the nozzle 7 of the present invention and improve the bathing and showering effect of the present invention.

[0056] In addition, in the present embodiment, the arc-shaped protruding sections on the separation ring 14 are arranged to have two corresponding left and right sections, so that two crescent-shaped water-jetting chambers 16 interconnected with each other are formed between the separation ring 14 and the side wall of the rotor 3, and two groups of water-jetting ports 141 and water-discharging ports 52 corresponding to the two water-jetting chambers 16 are provided on the separation ring 14 and the cover 5, respectively, so that water can enter the water-jetting chambers 16 on both sides at relative positions and flow counterclockwise in the same direction, thereby promoting the directional impact of water on the blades 34 to drive the rotor 3 to rotate counterclockwise, increasing the rotation force of the nozzle 7 of the present invention, and improving the massage effect of the present invention.

[0057] It should be noted that in this embodiment, the two groups of drain ports 52 and the water jet ports 141 are respectively arranged at the two ends of the crescent-shaped water jet cavity 16 on the same side, so that the water flow entering the water jet cavity 16 can only flow in the counterclockwise direction. This structural setting is only a preferred embodiment of the present invention and is not a limitation of the present invention. In some other embodiments, the positions of the drain ports 52 and the water jet ports 141 can also be interchanged, so that the water jet ports 141 are correspondingly located at the rear end of the crescent-shaped water jet cavity 16, and the drain ports 52 are correspondingly located at the front end of the crescent-shaped water jet cavity 16. After the interchange, the water flow entering the water jet cavity 16 can only flow in the clockwise direction to drive the rotor 3 to rotate in the clockwise direction.

[0058] It should also be noted that the position and number of the arc-shaped protruding sections, the water ejection ports 141, and the water drain ports 52 provided on the separator ring 14 in this embodiment are only a preferred embodiment of the present invention and are not limitations of the present invention. In other embodiments, the position and number of the arc-shaped protruding sections, the water ejection ports 141, and the water drain ports 52 on the separator ring 14 can be designed according to actual needs. For example, the arc-shaped protruding sections on the separator ring 14 can be set to three, and the water ejection ports 141 on the separator ring 14 and the water drain ports 52 on the cover 5 can be matched to three groups, etc.

[0059] It should also be noted that the arrangement and number of the eight groups of weight-reducing cavities 35, eight connecting bone positions 36 and eight blades 34 provided on the rotor 3 in this embodiment are not limitations of the present invention. In other embodiments, the arrangement and number of the weight-reducing cavities 35, connecting bone positions 36 and blades 34 can be adjusted. For example, the blades 34 can be arranged in an inclined manner, or the number of weight-reducing cavities 35, connecting bone positions 36 and blades 34 can be increased or decreased, etc., as long as the water flow in the water jet cavity 16 can impact the blades 34 and then drive the rotor 3 to rotate.

[0060] Specifically, refer to Figure 1 , Figure 2 , Figures 9 to 12 As shown, the spray head 7 of the present invention is a disc-shaped structure that matches the cavity opening of the circular groove head 12 of the shower housing 1. In order to ensure the massage effect of the present invention and increase the comfort of massage, the size and outward protrusion height of the massage head 71 on the spray head 7 of the present invention are not completely the same. At the same time, in order to ensure that the nozzle 72 does not affect the outward spraying of water during massage, the outward protrusion height of the nozzle 72 on the spray head 7 of the present invention is less than the protrusion height of the massage head 71.

[0061] Specifically, refer to Figures 9 to 11As shown, in this embodiment, the nozzles 72 on the nozzle 7 are radially arranged on the nozzle 7, and the massage heads 71 ​​are evenly distributed around the nozzles 72. Each nozzle 72 is provided with a water outlet 721 connected to the water storage chamber 18 for water to be ejected. A countersunk through hole 73 is provided at the center of the nozzle 7 for use with the connecting screw hole 311 on the extension part 31 of the rotor 3. Four positioning grooves 74 are also provided at the middle position of the bottom surface of the nozzle 7 facing the cover 5, which are engaged with the positioning columns 312 on the extension part 31.

[0062] Reference Figure 2 As shown, during actual assembly, the nozzle 7 is placed on the upper part of the cover 5 of the head 12 with the bottom surface facing the cover 5, so that the positioning groove 74 on the bottom surface of the nozzle 7 is matched and snapped onto the positioning column 312 on the extension 31 of the rotor 3, and then the nozzle 7 is matched and threadedly fixedly connected to the rotor 3 through the countersunk screw 8 through the countersunk through hole 73 and the connecting screw hole 311. After the threaded fixed connection, the nozzle 7 is coaxially linked with the rotor 3. The outer peripheral edge of the nozzle 7 is sealed and movably abutted against the inner side of the outer wall 13 of the head 12 to ensure that the water in the water storage chamber 18 will not leak out of the nozzle 7 from the outer peripheral edge of the nozzle 7.

[0063] Specifically, refer to Figure 1 and Figure 2 As shown, after the countersunk screw 8 is tightened, its nut is accommodated in the countersunk through hole 73. For the sake of aesthetics, water leakage prevention and avoiding rust of the nut of the countersunk screw 8, the present invention also provides a sealing plug 9 on the countersunk through hole 73 for sealing the countersunk through hole 73.

[0064] The nozzle 7 of the present invention blocks the upper opening of the head 12 cavity, and the outer periphery of the nozzle 7 is rotatably sealed and abutted against the inner side surface of the outer wall 13, ensuring that the water flow in the water storage chamber 18 can only be ejected outward through the water outlet 721 of the nozzle 72, which is beneficial to increase the water pressure in the water storage chamber 18, making the water spray from the nozzle 7 more powerful, thereby improving the bathing and flushing effect of the present invention.

[0065] In actual use, water flows through the handle 11 of the shower head of the present invention through the water inlet 131 into the water inlet chamber 15, and then flows into the water ejection chambers 16 on both sides and connected to each other through the two sets of corresponding water ejection ports 141 on the separation ring 14. The water entering the water ejection chambers 16 on both sides flows counterclockwise from one end of the water ejection ports 141 to one end of the drain port 52, and enters the water storage chamber 18 through the drain port 52. The water entering the water storage chamber 18 is ejected out of the spray head 7 through the water outlet 721 and the nozzle 72, forming a complete water path, realizing the function of the spray shower of the present invention.

[0066] The water flows out of the water jet chamber 16 in the counterclockwise direction and continuously impacts the blades 34 on the rotor 3, thereby driving the rotor 3 to rotate in the counterclockwise direction. During the rotation of the rotor 3, the blades 34 automatically elastically expand and contract as the curvature of the inner wall of the separation ring 14 changes, which is conducive to the water flow impacting the blades 34 and driving the rotor 3 to rotate continuously. When the rotor 3 rotates, the nozzle 7 threadedly fixedly connected to the rotor 3 is synchronously driven to rotate in the counterclockwise direction. During the rotation of the nozzle 7, the massage head 71 can be used to perform rotational massage and rubbing on human skin or animal fur, thereby realizing the massage function of the present invention.

[0067] The shower head of the present invention can be used to massage and rub while showering to relieve fatigue, and the massage effect is good. Moreover, for elderly people and children with inconvenient movements, the shower head of the present invention can also be used to rub and rinse the back and other parts that are not easily accessible, making bathing more convenient, and the cleaning effect and massage effect are better.

[0068] Specifically, refer to Fig. 9 and Fig.12 As shown, in order to improve the texture of the nozzle 7 of the present invention and increase the comfort of pressing and kneading the massage head 71, the nozzle 7 of the present invention is made of skin-friendly material, and a circular fixed plate 75 with a supporting and shaping function is embedded inside.

[0069] It should be noted that the fixing plate 75 needs to be provided with holes corresponding to the countersunk through hole 73 , the positioning groove 74 and the water outlet hole 721 to ensure that the nozzle 7 can be connected and fixed on the rotor and discharge water normally.

[0070] The skin-friendly material is coated on the fixing plate 75, so that the outermost edge of the spray head 7 can be elastically abutted against the inner side of the outer wall 13 of the head 12, playing a role of sealing and leak prevention. In order to further enhance the sealing and leak prevention effect at the outer edge of the spray head 7, the outer edge of the bottom surface of the spray head 7 of the present invention is also provided with an outer edge sealing edge 76 extending vertically to the top surface of the cover 5 and playing a sealing role. In the process of the spray head 7 rotating with the rotor 3, the outer edge sealing edge 76 of the skin-friendly material always rotates and abuts against the top surface of the cover 5 and the inner side of the outer wall 13, effectively preventing the water flow from the water storage chamber 18 through the outer edge gap of the spray head 7, and having a good sealing effect, which can effectively avoid the problem of leakage of the spray head 7 during use, and has higher reliability. At the same time, the outer edge sealing edge 76 is also conducive to increasing the water pressure in the water storage chamber 18, making the water output of the spray head 7 more powerful, and improving the effect of the bathing and showering of the present invention.

[0071] Preferably, the fixing plate 75 in this embodiment is made of stainless steel, and the skin-friendly material is silicone rubber, which is coated on the fixing plate 75 of stainless steel to form the nozzle 7. The fixing plate 75 of stainless steel can ensure the strength of the nozzle 7 and also play a role in rust prevention. The silicone rubber material itself has excellent heat resistance, cold resistance, acid and alkali resistance, and is soft and tough. The massage head 71 made of silicone rubber has a more comfortable texture, which is conducive to improving the massage effect.

[0072] Of course, in some other embodiments, the material of the fixing plate 75 can also be made of synthetic plastic or other metal materials with strong rigidity and toughness, and the main body of the nozzle 7 covering the fixing plate 75 can also be made of other skin-friendly materials such as rubber or silicone.

[0073] It should be noted that the water outlet holes 721 provided on the nozzle 72 in this embodiment can be either vertically provided or obliquely provided to radiate outward. The water outlet hole 721 provided vertically has a water outlet area smaller than the water outlet hole 721 provided obliquely. In actual production, the water outlet hole 721 of the nozzle 72 can be provided vertically or obliquely according to actual needs.

[0074] It should also be noted that the arrangement, quantity, shape and size of the massage heads 71 ​​and nozzles 72 on the spray head 7 in this embodiment are only a preferred embodiment of the present invention and are not intended to limit the present invention. In other embodiments, the nozzles 72 may be arranged in a circular or disorderly manner. Or in other embodiments, the massage head 71 may also be provided with a water outlet 721, so that the massage head 71 can be used for both massage and water spraying.

[0075] It should also be noted that the height of the nozzle 72 in this embodiment is designed to be slightly lower than the height of the massage head 71, which can ensure that when the massage head 71 contacts the human skin or other animal fur for massage, the normal water discharge of the nozzle 72 is not affected. Moreover, the water flow sprayed by the relatively low nozzle 72 can rinse the relatively high massage head 71, thereby cleaning the massage head 71. In other embodiments, the heights of the nozzle 72 and the massage head 71 can be adjusted according to actual needs.

[0076] Of course, the shower head of the present invention is not limited to daily bathing for humans, but can also be used for bathing and massage of pets and livestock. When bathing and rinsing animals, the animal's fur can be massaged and rubbed by the massage head 71 on the nozzle 7 of the present invention, eliminating the process of manual rubbing and facilitating use. Moreover, in the process of massaging and rubbing the animal's fur by the massage head 71, it can also relieve itching, making the animal's bathing more comfortable. Especially in some large-scale industrial livestock breeding enterprises, livestock can be massaged, rubbed and bathed by installing multiple enlarged joint plates of the present invention, which is not only convenient for bathing and cleaning of livestock, but also can be massaged and relieved of itching by rotating the massage head 71 on the nozzle 7. The application prospect is broad, and the production cost of the present invention is low, which is suitable for large-scale promotion and use.

[0077] It should be noted that, unless otherwise clearly specified and limited, terms such as "assembly", "connection", "connection", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral whole; it can be directly connected or indirectly connected through an intermediate medium.

[0078] The above embodiment is only for the purpose of describing a specific implementation of the present invention, and is not intended to limit the implementation of the present invention. For those skilled in the art, according to the principle of the present invention, only the water pressure is increased, or the multi-nozzle switching is modified, or the size is increased, reduced, or combined, etc., are all within the scope of protection of the claims of the present invention.

[0079] According to the principles of the present invention, other adjustments or modifications to the shower housing 1, the rotor 3, the cover 5 and the spray head 7 can be deduced and summarized, which will not be listed here one by one. Any modification, replacement or improvement made within the spirit and principle of the present invention should be included in the scope of protection of the claims of the present invention.
