Description

Technical Field

[0001] This article relates to the field of bathroom technology, specifically a massage spray head. Background Technology

[0002] Some existing bathroom fixtures have massage functions, such as bathtubs, showers, or foot baths. These fixtures typically have multiple water jets that spray water onto the body to provide a massage.

[0003] Water supply devices that supply water to multiple nozzles are bulky, which is not conducive to the layout of the nozzles, and the water supply devices can only provide a single pulse of water flow with a single tactile sensation. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this application provides a massage nozzle, which includes:

[0005] The shell is provided with a liquid collection chamber, a water outlet channel extending from one end of the liquid collection chamber to the outside of the shell, and a plurality of sub-channels penetrating the peripheral wall of the liquid collection chamber, wherein the plurality of sub-channels are arranged sequentially along the circumferential direction of the peripheral wall;

[0006] The impeller is rotatably connected to the housing and is provided with a shielding surface;

[0007] The impeller is driven to rotate by water flowing through the sub-channel. When the impeller rotates, the shielding surface can pass through the ends of the multiple sub-channels in sequence, and the shielding surface can block the end of the sub-channel that is being passed.

[0008] In one illustrative embodiment, the housing includes

[0009] An end cap includes a cylindrical body, a water outlet covering one end of the cylindrical body, and a convex ring disposed on the inner side of the water outlet, wherein an annular cavity is formed between the cylindrical body and the convex ring.

[0010] A cover plate is provided to cover the end of the convex ring that is away from the water outlet.

[0011] The convex ring, the water outlet, and the cover plate enclose the liquid collection cavity. The water outlet channel passes through the cover plate and is coaxial with the convex ring. The sub-channels are all arranged on the convex ring and pass through the convex ring.

[0012] In one illustrative embodiment, a plurality of grooves are provided at one end of the convex ring away from the end face, the grooves extending from the inner circumferential surface of the convex ring to the outer circumferential surface of the convex ring;

[0013] The cover plate covers the opening of the groove, and the inner surface of the groove and the surface of the cover plate covering the opening enclose the sub-channel.

[0014] In one illustrative embodiment, the cover plate is further provided with a guide post, one end of which is connected to the cover plate and the other end extends into the water outlet channel;

[0015] The guide post, the convex ring, and the water outlet channel are all coaxially arranged.

[0016] In one illustrative embodiment, the radius of the guide post gradually decreases from the cover plate to the water outlet channel.

[0017] In one illustrative embodiment, the cover plate has an annular protrusion on its surface facing the convex ring, the top of the protrusion abutting against the top of the convex ring.

[0018] In one illustrative embodiment, the blade is disposed within the liquid collection chamber;

[0019] The impeller includes:

[0020] The connecting ring has an outer peripheral surface that is clearance-fitted with the inner wall of the liquid collection cavity; and

[0021] The blade, connected to the connecting ring, includes a front end and an end opposite to the front end, the end being provided with a force-bearing surface;

[0022] The sub-channel drives the impeller to rotate by spraying water onto the force-bearing surface, and the shielding surface is the outer side of the blade.

[0023] In one illustrative embodiment, the force-bearing surface is located on the outer side of the end, and the force-bearing surface is constructed as a concave arc surface.

[0024] In one illustrative embodiment, at least a portion of the sub-channel extends radially along the collection cavity; and / or

[0025] At least a portion of the subchannels do not extend radially along the collection chamber.

[0026] In one illustrative embodiment, the width of the front end is smaller than the width of the end end.

[0027] In one illustrative embodiment, multiple blades are provided, and the multiple blades are evenly distributed on the connecting ring.

[0028] In one illustrative embodiment, the distance from the blade to the axis of the connecting ring is less than the radius of the water outlet channel.

[0029] In one illustrative embodiment, the cover plate also seals the end of the cylinder opposite to the water outlet.

[0030] The cover plate is provided with an acceleration hole that communicates with the annular cavity;

[0031] The impeller is disposed in the annular cavity, and the impeller includes a connecting ring sleeved on the convex ring, blades extending outward from the connecting ring, and a baffle connected to the connecting ring;

[0032] The shielding surface is the inner side of the baffle;

[0033] The acceleration hole can inject water into the annular cavity, and the acceleration hole drives the impeller to rotate by obliquely spraying water onto the blades.

[0034] In one illustrative embodiment, the extension direction of the acceleration hole is at an angle to the axis of the connecting ring.

[0035] When using this massage nozzle, multiple sub-channels simultaneously inject water into the collection chamber. Some sub-channels are blocked by the shielding surface, preventing water from entering the collection chamber. As the water flows through the impeller, it drives the impeller to rotate. As the impeller rotates, it rotates the water flow, which is then sprayed out of the housing through the outlet channel. Simultaneously, the shielding surface of the impeller, as it rotates, passes sequentially over the inward-facing ends of multiple sub-channels, blocking the ends of the sub-channels it passes through, preventing them from continuing to inject water into the collection chamber. Thus, as the shielding surface alternately blocks and moves away from the ends of the sub-channels, the water flow intermittently impacts the collection chamber. Ultimately, the water flow output from the outlet channel has a pulsating sensation in both directions parallel and perpendicular to the outlet channel, creating a dual massage experience of pressing and kneading.

[0036] These massage jets are small in size and have a simple structure, making them more flexible when placed in a bathtub.

[0061] Example 1

[0062] like Figure 1-3 As shown, Figure 1-3 The massage nozzle 1 in Embodiment 1 is shown. The massage nozzle 1 includes a housing 2 and an impeller 3. The impeller 3 is disposed within the housing 2.

[0063] The housing 2 includes an outer cylinder 21, an end cap 22, and a cover plate 23. The outer cylinder 21 has a tubular structure. The end cap 22 covers one end of the outer cylinder 21 and is connected to the outer cylinder 21. The end of the outer cylinder 21 opposite to the end cap 22 is used to connect to an external water supply pipe, which injects water into the outer cylinder 21.

[0064] The end cap 22 includes a cylindrical body 221, a water outlet 222, and a raised ring 223. The cylindrical body 221 has a cylindrical structure. The water outlet 222 covers one end of the cylindrical body 221. An external thread is provided on the outer circumferential surface of the cylindrical body 221, and an internal thread matching the external thread is provided on the outer cylinder 21. The cylindrical body 221 is screwed into the outer cylinder 21 to form a threaded connection between them.

[0065] The water outlet 222 is annular in shape. The water outlet 222 seals the end of the cylinder 221. A water outlet channel 224 is provided on the water outlet 222, which extends through the water outlet 222. The water outlet channel 224 is a straight channel, and its cross-section can be circular. The water outlet channel 224 is coaxially arranged with the cylinder 221.

[0066] like Figure 2 As shown, the convex ring 223 is circular in shape. The convex ring 223 is disposed on the plate surface of the water outlet 222 facing the inside of the cylinder 221. The convex ring 223 surrounds the water outlet channel 224. The convex ring 223 and the water outlet channel 224 are coaxially arranged. The inner cavity of the convex ring 223 is connected to the water outlet channel 224. Multiple grooves 226 are provided on the end of the convex ring 223 facing away from the water outlet 222. The grooves 226 are formed by indentation from the end face of the convex ring 223. The grooves 226 extend from the inner circumferential surface of the convex ring 223 to the outer circumferential surface of the convex ring 223. The multiple grooves 226 are arranged sequentially along the circumference of the convex ring 223. The outer diameter of the convex ring 223 is smaller than the inner diameter of the cylinder 221, forming an annular cavity 225 between the convex ring 223 and the cylinder 221.

[0067] The cover plate 23 is disc-shaped. It covers the end of the cylinder 221 opposite to the water outlet 222. It also covers the end of the annular cavity 225 opposite to the water outlet 222. The cover plate 23 abuts against the end of the convex ring 223 opposite to the water outlet 222. The convex ring 223, the water outlet 222, and the cover plate 23 enclose a liquid collecting cavity 227. The cover plate 23 also covers the opening of the grooves 226 of the convex ring 223. The inner surface of each groove 226 and the surface of the cover plate 23 facing the groove 226 enclose a sub-channel 220. The two ends of the sub-channel 220 connect the liquid collecting cavity 227 to the annular cavity 225. The sub-channel 220 can be a straight channel. An acceleration hole 231 is provided on the cover plate 23. The acceleration hole 231 is located on the edge of the cover plate 23. Multiple acceleration holes 231 can be provided, and the multiple acceleration holes 231 are evenly distributed in the circumferential direction of the cover plate 23. The acceleration holes 231 are connected to the annular cavity 225.

[0068] like Figure 5 As shown, the impeller 3 is disposed within the liquid collecting chamber 227. The impeller 3 includes a connecting ring 31 and blades 32. The connecting ring 31 is circular. The connecting ring 31 is coaxially arranged with the convex ring 223, and the outer circumferential surface of the connecting ring 31 is in clearance fit with the inner circumferential surface of the convex ring 223, that is, the outer circumferential surface of the connecting ring 31 is in clearance fit with the inner wall of the liquid collecting chamber 227. The impeller 3 can rotate around its own axis within the liquid collecting chamber 227. The connecting ring 31 abuts against the water outlet 222, and the sub-channels 220 on the convex ring 223 are all located on the side of the connecting ring 31 away from the water outlet 222, and the connecting ring 31 does not obstruct the sub-channels 220.

[0069] like Figure 2 As shown, the blade 32 has a generally wedge-shaped structure. The blade 32 is connected to the connecting ring 31. The blade 32 includes a front end 321 and a rear end 322 opposite to the front end 321. The front end 321 of the blade 32 faces the rotation direction of the impeller 3, and the rear end 322 of the blade 32 faces the opposite direction of rotation of the impeller 3. A force-bearing surface 323 is provided on the rear end 322 of the blade 32, and the force-bearing surface 323 is obliquely outward. Figure 8 As shown, when the subchannel 220 injects water into the liquid collection chamber 227, it can reach the force-bearing surface 323 of the blade 32, so that the blade 32 is subjected to a forward thrust, thereby driving the impeller 3 to rotate.

[0070] Along the axis of the impeller 3, the thickness of the blade 32 is greater than the thickness of the connecting ring 31. The blade 32 extends from the connecting ring 31 toward the sub-channel 220, and the blade 32 can block the inward end of the sub-channel 220. The outward side of the blade 32 is the blocking surface 320, that is, the side of the blade 32 near the inner circumferential surface of the convex ring 223 is the blocking surface 320. The blocking surface 320 is constructed as an arc surface coaxial with the convex ring 223, and the blade 32 blocks the inward end of the sub-channel 220 through the blocking surface 320.

[0071] like Figure 6 , 8 As shown, after water is injected into the outer cylinder 21 through the water supply pipe, the water in the outer cylinder 21 enters the annular cavity 225 through the acceleration hole 231 on the cover plate 23. During the process of water flowing from the outer cylinder 21 into the acceleration hole 231, the cross-sectional area of ​​the flow channel suddenly decreases, which increases the flow velocity of the water, thus making the water flow velocity into the annular cavity 225 larger. The water in the annular cavity 225 is injected into the liquid collection cavity 227 through multiple sub-channels 220. At least some of the sub-channels 220 can spray water onto the force-bearing surface 323 of the blade 32 to drive the impeller 3 to rotate. At the same time, some of the sub-channels 220 are blocked by the shielding surface 320 of the blade 32 and cannot inject water into the liquid collection cavity 227. When the impeller 3 rotates, it drives the water in the collection chamber 227 to rotate. The rotating water flow is sprayed out of the housing 2 through the water outlet channel 224. At the same time, the shielding surface 320 of the impeller 3 passes through the inward ends of multiple sub-channels 220 in turn as it rotates. The shielding surface 320 blocks the ends of the sub-channels 220 it passes through, preventing the sub-channels 220 from continuing to inject water into the collection chamber 227. In this way, as the shielding surface 320 alternately blocks and leaves the ends of the sub-channels 220, the water flow intermittently impacts the collection chamber 227. Finally, the water flow output from the water outlet channel 224 has a pulsating sensation in both the direction parallel to and perpendicular to the water outlet channel 224, thus forming a dual massage sensation of pressing and kneading.

[0072] In one illustrative embodiment, a guide post 232 is also provided on the cover plate 23. One end of the guide post 232 is connected to the middle of the cover plate 23 and is located on the side of the cover plate 23 near the water outlet channel 224. The other end of the guide post 232 extends into the water outlet channel 224. The diameter of the portion of the guide post 232 extending into the water outlet channel 224 is smaller than the inner diameter of the water outlet channel 224. An annular gap is formed between the guide post 232 and the water outlet channel 224.

[0073] Multiple streams of water injected into the collection chamber 227 through multiple sub-channels 220 can move toward the outlet channel 224 under the guidance of the guide column 232. At the same time, due to the impeller 3 driving the water to rotate, these streams can also rotate around the guide column 232 and flow into the outlet channel 224.

[0074] In one illustrative embodiment, the radius of the end of the guide post 232 connected to the cover plate 23 is greater than the radius of the end of the guide post 232 extending into the water outlet channel 224. The radius of the guide post 232 gradually decreases in the direction from the cover plate 23 to the water outlet channel 224.

[0075] In this way, the outer peripheral surface of the guide column 232 and the water flow sprayed from the water outlet channel 224 form an obtuse angle, so that the water flow loses little velocity when it hits the guide column 232.

[0076] In one illustrative embodiment, the cover plate 23 is further provided with a protrusion 233, which is annular. The protrusion 233 is provided on the surface of the cover plate 23 facing the protruding ring 223. The top end of the protrusion 233 facing away from the cover plate 23 abuts against the top end of the protruding ring 223 facing away from the water outlet 222. Since the protrusion 233 abuts against the protruding ring 223, the seal between the cover plate 23 and the protruding ring 223 is strengthened.

[0077] In one illustrative embodiment, such as Figure 2 , 8 As shown, the force-bearing surface 323 on the blade 32 is located on the outer side of the end 322 of the blade 32. The force-bearing surface 323 is constructed as a concave arc surface.

[0078] When a portion of the subchannel 220 extends radially along the convex ring 223, this subchannel 220 sprays water onto the arc-shaped force-bearing surface 323, causing the blade 32 to be subjected to a forward component force, thereby driving the blade 32 to rotate.

[0079] Another part of the sub-channel 220 does not extend radially along the convex ring 223. This part of the sub-channel 220 can also spray water onto the arc-shaped force-bearing surface 323, so that the blade 32 is subjected to a forward component force, and this component force is greater than the forward component force applied by the water sprayed by the radially extended sub-channel 220. After being subjected to this thrust, the blade 32 can rotate faster.

[0080] In particular, the force-bearing surface 323 of this concave arc structure can make more efficient use of the impact force of the water flow when it is impacted by the water flow, converting the impact force into forward component force as much as possible, so that the impeller 3 can rotate faster.

[0081] In one illustrative embodiment, the width of the front end 321 of the blade 32 is smaller than the width of the rear end 322 of the blade 32. This results in less water resistance for the blade 32 during rotation, allowing the impeller 3 to rotate faster.

[0082] In one illustrative embodiment, the distance from the axis of the blade 32 to the connecting ring 31 is less than the radius of the water outlet channel 224.

[0083] In this way, when using the massage nozzle 1, the user can see the blade 32 rotating through the water outlet channel 224, allowing the user to more directly observe whether the massage nozzle 1 is working, thus improving the experience.

[0084] In one illustrative embodiment, such as Figure 10 , 11 As shown, multiple blades 32 are provided, for example, two. These multiple blades 32 are evenly distributed on the connecting ring 31. Each blade 32 can simultaneously interrupt multiple sub-channels 220.

[0085] In this way, when impeller 3 is impacted by water flow, the force on impeller 3 is more even, and the rotation of impeller 3 is more balanced.

[0086] In some embodiments, such as Figure 12 , 13 As shown, blade 32a can also be configured as a single unit.

[0087] The number of blades 32a can be flexibly set according to requirements.

[0088] In some embodiments, such as Figure 14 , 15 As shown, multiple blades 32b can be set, and each blade 32b can only cut off one sub-channel 220 at a time.

[0089] The number of sub-channels 220 that each blade 32b can cut off can be flexibly set according to requirements.

[0090] Example 2

[0091] like Figure 16-21 As shown, Figure 16-21 The massage nozzle 1d of Embodiment 2 is shown. The massage nozzle 1d includes a housing 2d and an impeller 3d. The impeller 3d is disposed within the housing 2d.

[0092] like Figure 18 , 19 As shown, the shell 2d includes an outer cylinder 21d, an end cap 22d, and a cover plate 23d. The outer cylinder 21d has a tubular structure. The end cap 22d covers one end of the outer cylinder 21d and is connected to the outer cylinder 21d. The end of the outer cylinder 21d facing away from the end cap 22d is used to connect to an external water supply pipe, which injects water into the outer cylinder 21d.

[0093] like Figure 17 , 18 As shown, the end cap 22d includes a cylindrical body 221d, a water outlet 222d, and a convex ring 223d. The cylindrical body 221d has a cylindrical structure. The water outlet 222d covers one end of the cylindrical body 221d. An external thread is provided on the outer circumferential surface of the cylindrical body 221d, and an internal thread matching the external thread is provided on the outer cylinder 21d. The cylindrical body 221d is screwed into the outer cylinder 21d to form a threaded connection with the outer cylinder 21d.

[0094] like Figure 17 As shown, the water outlet 222d is annular in shape. The water outlet 222d blocks the end of the cylinder 221d. A water outlet channel 224d is provided on the water outlet 222d, which penetrates the water outlet 222d. The water outlet channel 224d is a straight channel, and its cross-section can be circular. The water outlet channel 224d is coaxially arranged with the cylinder 221d.

[0095] The convex ring 223d is circular in shape. It is positioned on the plate surface of the water outlet 222d facing the inner surface of the cylinder 221d. The convex ring 223d surrounds the water outlet channel 224d. The convex ring 223d and the water outlet channel 224d are coaxially aligned. The inner cavity of the convex ring 223d communicates with the water outlet channel 224d. Multiple grooves 226d are provided on the end of the convex ring 223d facing away from the water outlet 222d. The grooves 226d are formed by indentation from the end face of the convex ring 223d. The grooves 226d extend from the inner circumferential surface of the convex ring 223d to its outer circumferential surface. The multiple grooves 226d are arranged sequentially along the circumference of the convex ring 223d. The outer diameter of the convex ring 223d is smaller than the inner diameter of the cylinder 221d, forming an annular cavity 225d between the convex ring 223d and the cylinder 221d.

[0096] like Figure 17 , 19 As shown in Figure 22, the cover plate 23d is disc-shaped. The cover plate 23d covers one end of the cylinder 221d opposite to the water outlet 222d. The cover plate 23d also covers one end of the annular cavity 225d opposite to the water outlet 222d. The cover plate 23d also abuts against one end of the convex ring 223d opposite to the water outlet 222d. The convex ring 223d, the water outlet 222d, and the cover plate 23d enclose a liquid collecting cavity 227d. The cover plate 23d also covers the opening of the groove 226d of the convex ring 223d. The inner surface of each groove 226d and the surface of the cover plate 23d facing the groove 226d enclose a sub-channel 220d. The two ends of the sub-channel 220d connect the liquid collecting cavity 227d to the annular cavity 225d. The sub-channel 220d can be a straight channel. An acceleration hole 231d is provided on the cover plate 23d. Acceleration holes 231d are located on the edge of cover plate 23d. Multiple acceleration holes 231d can be provided, and the multiple acceleration holes 231d are evenly distributed in the circumferential direction of cover plate 23d. Acceleration holes 231d are connected to annular cavity 225d.

[0097] Impeller 3d is disposed within an annular cavity 225d. Impeller 3d includes a connecting ring 31d, blades 32d, and baffles 33d. The connecting ring 31d is constructed as a ring. The connecting ring 31d is fitted onto the convex ring 223d. A clearance fit is formed between the inner circumferential surface of the connecting ring 31d and the outer circumferential surface of the convex ring 223d. The connecting ring 31d can rotate around the convex ring 223d.

[0098] Multiple blades 32d are provided, all extending outward from the connecting ring 31d. The blades 32d can be involute, cycloidal, or straight. The acceleration hole 231d on the cover plate 23d is constructed as an oblique hole, with its extension direction forming an angle with the axis of the connecting ring 31d. When water is injected into the annular cavity 225d through the acceleration hole 231d, the water flow obliquely impacts the blades 32d, thereby driving the impeller 3d to rotate.

[0099] Baffle 33d is connected to connecting ring 31d. Baffle 33d is constructed as an arc-shaped plate. The inner surface of baffle 33d is a shielding surface 331d, which is an arc surface. This shielding surface 331d faces the convex ring 223d and is clearance-fitted with the outer peripheral surface of the convex ring 223d. The shielding surface 331d can shield a portion of the outward-facing end of the sub-channel 220d.

[0100] After water is injected into the outer cylinder 21d through the water supply pipe, the water in the outer cylinder 21d enters the annular cavity 225d through the acceleration hole 231d on the cover plate 23d. The acceleration hole 231d accelerates the water flow, resulting in a higher velocity of the water entering the annular cavity 225d. The water flow is sprayed onto the blades 32d, causing the impeller 3d to rotate. As the impeller 3d rotates, it drives the water in the annular cavity 225d to rotate. This rotating water flow is injected into the liquid collection chamber 227d through the sub-channel 220d, and then sprayed out of the shell 2d through the water outlet channel 224d.

[0101] like Figure 18 , 21 As shown, water in the annular cavity 225d is injected into the liquid collection cavity 227d through multiple sub-channels 220d. At least a portion of the sub-channels 220d can spray water onto the force-bearing surface 323d of the blade 32d to drive the impeller 3d to rotate. At the same time, a portion of the sub-channels 220d are blocked by the shielding surface 331d of the blade 32d and cannot inject water into the liquid collection cavity 227d. When the impeller 3d rotates, the shielding surface 331d passes through the outward ends of multiple sub-channels 220d in sequence. The shielding surface 331d blocks the ends of the sub-channels 220d it passes through, preventing the sub-channels 220d from continuing to inject water into the collection chamber 227d. In this way, the shielding surface 331d causes the water flow to intermittently impact the collection chamber 227d by blocking and opening the ends of the sub-channels 220d. Finally, the water flow output from the water outlet channel 224d has a pulsating sensation in both the direction parallel to and perpendicular to the water outlet channel 224d, thus forming a dual massage sensation of pressing and kneading.

[0102] In one illustrative embodiment, such as Figure 19 , 21 As shown, a guide post 232d is also provided on the cover plate 23d. One end of the guide post 232d is connected to the middle of the cover plate 23d and is located on the side of the cover plate 23d near the water outlet channel 224d. The other end of the guide post 232d extends into the water outlet channel 224d. The diameter of the portion of the guide post 232d extending into the water outlet channel 224d is smaller than the inner diameter of the water outlet channel 224d. An annular gap is formed between the guide post 232d and the water outlet channel 224d.

[0103] Multiple streams of water injected into the collection chamber 227d through multiple sub-channels 220d can move toward the outlet channel 224d under the guidance of the guide column 232d. At the same time, due to the impeller 3d driving the water flow to rotate, these streams can also rotate around the guide column 232d and flow into the outlet channel 224d.
