Detailed Description

Example one

Referring to fig. 1 to 3, fig. 1 to 3 show a massage nozzle 1 according to a first embodiment. The massage nozzle 1 comprises a housing 2 and an impeller 3. The impeller 3 is disposed within the housing 2.

The housing 2 includes an outer cylinder 21, an end cap 22, and a cover plate 23. The outer cylinder 21 is constructed in 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 facing away from the end cap 22 is used for externally connecting a water supply pipeline which injects water into the outer cylinder 21.

The end cap 22 includes a barrel 221, a water outlet portion 222, and a male ring 223. The drum 221 is configured as a cylindrical structure. The water outlet portion 222 covers one end of the cylinder 221. An external thread is provided on the outer circumferential surface of the cylinder 221, an internal thread matching the external thread is provided on the outer cylinder 21, and the cylinder 221 is screwed into the outer cylinder 21 to be in threaded connection with the outer cylinder 21.

The water outlet portion 222 is formed in an annular shape. The water outlet portion 222 closes the end of the cylinder 221. The water outlet portion 222 is provided with a water outlet passage 224, and the water outlet passage 224 penetrates the water outlet portion 222. The water outlet passage 224 is a straight passage, and the cross section thereof may be circular. The water outlet passage 224 is provided coaxially with the cylinder 221.

As shown in fig. 2, the male ring 223 is configured in a ring shape. The convex ring 223 is disposed on the surface of the water outlet portion 222 facing the inside of the cylinder 221. The convex ring 223 surrounds the water outlet passage 224. The convex ring 223 is coaxially disposed with the water outlet passage 224. The inner cavity of the convex ring 223 is communicated with the water outlet passage 224. The end of the male ring 223 facing away from the outlet portion 222 is provided with a plurality of grooves 226. The groove 226 is formed by an end surface of the convex ring 223 being depressed inward. The groove 226 extends from the inner peripheral surface of the male ring 223 to the outer peripheral surface of the male ring 223. The plurality of grooves 226 are arranged in series in the circumferential direction of the male ring 223. The external diameter of the collar 223 is smaller than the internal diameter of the barrel 221, and an annular cavity 225 is formed between the collar 223 and the barrel 221.

The cover plate 23 is configured in a disk shape. The cover plate 23 covers the end of the cylinder 221 away from the water outlet part 222. The cover plate 23 also covers the end of the annular chamber 225 facing away from the water outlet 222. The cover plate 23 also abuts the end of the collar 223 facing away from the outlet portion 222. The collar 223, the outlet portion 222 and the cover plate 23 enclose a liquid collection chamber 227. The cover plate 23 also covers the openings of the grooves 226 of the collar 223, and 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 ends of the sub-channels 220 communicate the liquid collection chamber 227 with the annular chamber 225. The sub-channel 220 may be a straight channel. The cover plate 23 is provided with an acceleration hole 231. The acceleration hole 231 is provided at the edge of the cover plate 23. The acceleration holes 231 may be provided in plural, and the plural acceleration holes 231 are uniformly distributed in the circumferential direction of the cover plate 23. The acceleration orifice 231 communicates with the annular chamber 225.

As shown in fig. 5, the impeller 3 is disposed in the sump 227. The impeller 3 includes a connection ring 31 and blades 32. The connection ring 31 is configured as a circular ring. The connecting ring 31 is coaxially arranged with the convex ring 223, and the outer peripheral surface of the connecting ring 31 is in clearance fit with the inner peripheral surface of the convex ring 223, i.e. the outer peripheral surface of the connecting ring 31 is in clearance fit with the inner wall of the liquid collecting cavity 227. The impeller 3 is able to rotate about its axis within the sump 227. The connecting ring 31 abuts against the water outlet portion 222, 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 portion 222, and the connecting ring 31 does not block the sub-channels 220.

As shown in FIG. 2, the blades 32 are configured in a generally wedge-shaped configuration. The blades 32 are connected to the connection ring 31. The blade 32 includes a front end 321 and a tip end 322 opposite the front end 321. The leading ends 321 of the blades 32 face in the rotation direction of the impeller 3, and the distal ends 322 of the blades 32 face in the opposite direction to the rotation direction of the impeller 3. The tip 322 of the blade 32 is provided with a force-bearing surface 323, and the force-bearing surface 323 is inclined outward. As shown in fig. 8, the water injected into the liquid collecting chamber 227 by the sub-channel 220 can rush to the force bearing surface 323 of the vane 32, so that the vane 32 is pushed forward, thereby driving the impeller 3 to rotate.

The thickness of the blades 32 is greater than that of the connection ring 31 on the axis of the impeller 3. The blades 32 extend from the connecting ring 31 toward the side of the sub-passage 220, and the blades 32 can shield the inward end of the sub-passage 220. The outward side of the blade 32 is the shielding surface 320, i.e. the side of the blade 32 close to the inner circumferential surface of the convex ring 223 is the shielding surface 320. The shielding surface 320 is configured as a circular arc surface coaxial with the convex ring 223, and the blade 32 shields the inward end of the sub-passage 220 through the shielding surface 320.

As shown in fig. 6 and 8, after the 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, and the flow velocity of the water flow is increased due to the sudden reduction of the cross-sectional area of the flow passage in the process that the water flow flows into the acceleration hole 231 from the outer cylinder 21, so that the water flow velocity entering the annular cavity 225 is high. The water in the annular chamber 225 is injected into the liquid collecting chamber 227 through a plurality of sub-channels 220, at least a part of the sub-channels 220 can inject the water to the force bearing surfaces 323 of the blades 32 to drive the impeller 3 to rotate, and at the same time, a part of the sub-channels 220 are blocked by the shielding surfaces 320 of the blades 32 and cannot inject the water into the liquid collecting chamber 227. When the impeller 3 rotates, the impeller 3 drives the water in the liquid collecting cavity 227 to rotate, the rotating water flow is sprayed out of the shell 2 through the water outlet channel 224, meanwhile, the shielding surface 320 of the impeller 3 sequentially passes through the inward end parts of the plurality of sub-channels 220 when rotating, the shielding surface 320 can shield the end parts of the sub-channels 220 through which the shielding surface 320 passes, so that the sub-channels 220 cannot continuously inject water into the liquid collecting cavity 227, in this way, the shielding surface 320 intermittently impacts the liquid collecting cavity 227 when shielding and leaving the end parts of the sub-channels 220 in turn, and finally, the water flow output from the water outlet channel 224 has pulse feeling in the directions parallel to the water outlet channel 224 and perpendicular to the water outlet channel 224, so that double massage feeling of pressing and kneading is formed.

In an exemplary embodiment, the cover plate 23 is further provided with a guide post 232. One end of the guiding column 232 is connected to the middle part of the cover plate 23 and is located at one side of the cover plate 23 close to the water outlet channel 224. The other end of the guide post 232 extends into the outlet passage 224. The diameter of the portion of the guide post 232 extending into the outlet passage 224 is smaller than the inner diameter of the outlet passage 224. An annular gap is formed between the guide post 232 and the water outlet passage 224.

The plurality of water flows respectively injected into the liquid collecting chamber 227 by the plurality of sub-passages 220 can move in the direction of the water outlet passage 224 under the guidance of the guide posts 232, and can also flow into the water outlet passage 224 around the guide posts 232 due to the rotation of the water flow driven by the impeller 3.

In an exemplary embodiment, the radius of the end of the guide post 232 connected to the cover plate 23 is larger than the radius of the end of the guide post 232 extending into the outlet passage 224. The guide post 232 has a radius gradually decreasing in a direction from the cover plate 23 to the water outlet passage 224.

Thus, an obtuse angle is formed between the outer peripheral surface of the guide post 232 and the water flow ejected from the water outlet passage 224, and the loss speed of the water flow when the water flow hits the guide post 232 is small.

In an exemplary embodiment, the cover plate 23 is further provided with a protrusion 233, and the protrusion 233 has a ring shape. The projection 233 is provided on the plate surface of the cover plate 23 facing the convex ring 223. The top end of the protrusion 233 facing away from the cover plate 23 abuts against the top end of the convex ring 223 facing away from the water outlet 222. The seal between the cover plate 23 and the collar 223 is enhanced by the abutment of the projection 233 against the collar 223.

In an exemplary embodiment, as shown in fig. 2 and 8, the force-bearing surface 323 on the blade 32 is disposed on an outer side of the tip 322 of the blade 32. The force-bearing surface 323 is configured as a concave arc surface.

When a part of the sub-channel 220 extends in the radial direction of the convex ring 223, the part of the sub-channel 220 sprays water onto the arc-shaped force-bearing surface 323, so that the vane 32 receives a forward component of force, thereby pushing the vane 32 to rotate.

The other part of the sub-channels 220 does not extend along the radial direction of the convex ring 223, and this part of the sub-channels 220 can also spray water onto the cambered surface-shaped force-bearing surface 323, so that the vane 32 can be subjected to a forward component force, which is greater than the forward component force applied by the water sprayed from the radially extending sub-channels 220, and the vane 32 can rotate faster after the forward component force is applied.

In particular, the force-bearing surface 323 of the concave cambered surface structure can utilize the impact force of the water flow more efficiently when being impacted by the water flow, so that the impact force is converted into a forward component as much as possible, and the impeller 3 can rotate faster.

In an exemplary embodiment, the width of the leading end 321 of the blade 32 is less than the width of the trailing end 322 of the blade 32. Thus, the blades 32 are less resistant to water when rotated and the impeller 3 can be rotated faster.

In an exemplary embodiment, the distance from the blades 32 to the axis of the connection ring 31 is less than the radius of the outlet passage 224.

Thus, when the massage spray head 1 is used, a user can see the rotation of the blades 32 from the water outlet channel 224, so that the user can more intuitively see whether the massage spray head 1 works or not, and the experience is improved.

In an exemplary embodiment, as shown in fig. 10 and 11, the blade 32 is provided in a plurality, for example 2. The plurality of blades 32 are uniformly distributed on the connection ring 31. Each vane 32 may simultaneously intercept multiple sub-channels 220.

Thus, when the impeller 3 is impacted by the water flow, the force applied to the impeller 3 is more uniform, and the rotation of the impeller 3 is more balanced.

In some embodiments, as shown in fig. 12 and 13, only one blade 32a may be provided.

The number of blades 32a can be flexibly set as desired.

In some embodiments, as shown in fig. 14 and 15, the plurality of blades 32b may be provided, and each blade 32b can only block one sub-channel 220 at a time.

The number of sub-channels 220 that can be intercepted by each vane 32b can be flexibly set as desired.

One end of the outer cylinder 21d, which is away from the end cap 22d, is used for externally connecting a water supply pipeline, and the water supply pipeline injects water into the outer cylinder 21d.

As shown in fig. 17 and 18, the end cap 22d includes a cylinder 221d, a water outlet portion 222d, and a convex ring 223d. The cylinder 221d is configured as a cylindrical structure. The outlet 222d covers one end of the cylinder 221 d. An external thread is arranged on the outer peripheral surface of the cylinder 221d, an internal thread matched with the external thread is arranged on the outer cylinder 21d, and the cylinder 221d is screwed into the outer cylinder 21d to be in threaded connection with the outer cylinder 21d.

As shown in fig. 17, the water outlet portion 222d is formed in an annular shape. The water outlet portion 222d closes the end of the cylinder 221 d. The water outlet portion 222d is provided with a water outlet passage 224d, and the water outlet passage 224d penetrates the water outlet portion 222d. The outlet passage 224d is a straight passage, and may have a circular cross section. The water outlet passage 224d is provided coaxially with the cylinder 221 d.

The convex ring 223d is annular. The convex ring 223d is provided on the plate surface of the water outlet portion 222d facing the inside of the cylinder 221 d. The convex ring 223d surrounds the outlet passage 224 d. The convex ring 223d is disposed coaxially with the water outlet passage 224 d. The inner cavity of the convex ring 223d is communicated with the water outlet passage 224 d. The end of the convex ring 223d facing away from the water outlet portion 222d is provided with a plurality of grooves 226d. The groove 226d is formed by an end surface of the convex ring 223d being depressed inward. The grooves 226d extend from the inner peripheral surface of the convex ring 223d to the outer peripheral surface of the convex ring 223d. The plurality of grooves 226d are arranged in series in the circumferential direction of the convex ring 223d. The outer diameter of the collar 223d is smaller than the inner diameter of the barrel 221d, and an annular cavity 225d is formed between the collar 223d and the barrel 221 d.

As shown in fig. 17, 19, and 22, the cover plate 23d is configured in a disk shape. The cover plate 23d covers the end of the cylinder 221d away from the water outlet 222d. A cover plate 23d covers the end of the annular chamber 225d facing away from the water outlet portion 222d. The cover plate 23d also abuts the end of the male ring 223d facing away from the outlet portion 222d. The convex ring 223d, the water outlet portion 222d and the cover plate 23d enclose the liquid collecting chamber 227d. The cover plate 23d also covers the openings of the slots 226d of the collar 223d, and the inner surface of each slot 226d and the surface of the cover plate 23d facing the slot 226d enclose a sub-passage 220d. The two ends of the sub-channel 220d connect the plenum 227d with the annular cavity 225d. The sub-channel 220d may be a straight channel. The cover plate 23d is provided with an acceleration hole 231d. The acceleration hole 231d is provided at the edge of the cover plate 23d. The acceleration hole 231d may be provided in plural, and the plural acceleration holes 231d are uniformly distributed in the circumferential direction of the cover plate 23d. The acceleration bore 231d communicates with the annular cavity 225d.

The impeller 3d is disposed within the annular cavity 225d. The impeller 3d includes a connection ring 31d, blades 32d, and a baffle 33d. The connection ring 31d is configured as a circular ring. The connection ring 31d is fitted over the convex ring 223d. A clearance fit is formed between the inner peripheral surface of the connection ring 31d and the outer peripheral surface of the protruding ring 223d. The connection ring 31 can rotate around the convex ring 223d.

The blades 32d are provided in plural, and the plural blades 32d are protruded outwardly from the connection ring 31d. The blade 32d may be an involute, cycloid, or straight blade 32d. The accelerating hole 231d of the cover plate 23d is configured as an inclined hole, and the direction of extension of the accelerating hole 231d forms an angle with the axis of the connecting ring 31d. When the accelerating holes 231d are filled with water to the annular cavity 225d, the water flow obliquely hits the blades 32d, so that the impeller 3d is pushed to rotate.

The baffle 33d is connected to the connection ring 31d. The baffle 33d is configured as an arc-shaped plate. The inner surface of the shutter 33d is a shielding surface 331d and is a circular arc surface. The shielding surface 331d faces the protruding ring 223d, and is in clearance fit with the outer peripheral surface of the protruding ring 223d. The shielding surface 331d can shield a portion of the outward end of the sub-passage 220d.

After the water supply pipe injects water into the outer cylinder 21d, the water in the outer cylinder 21d enters the annular cavity 225d through the acceleration hole 231d on the cover plate 23d, and the acceleration hole 231d can accelerate the water flow, so that the water flow entering the annular cavity 225d has a high speed. The water jet is jetted to the blades 32d to rotate the impeller 3d. When the impeller 3d rotates, the impeller 3d rotates the water in the annular cavity 225d, and the rotating water is injected into the liquid collecting cavity 227d through the sub-channel 220d and is ejected out of the housing 2d through the water outlet channel 224 d.

As shown in fig. 18 and 21, the water in the annular chamber 225d is injected into the liquid collecting chamber 227d through a plurality of sub-passages 220d, at least a part of the sub-passages 220d can inject the water to the force receiving surfaces 323d of the vanes 32d to drive the impeller 3d to rotate, and at the same time, a part of the sub-passages 220d are blocked by the blocking surfaces 331d of the vanes 32d and cannot inject the water into the liquid collecting chamber 227d. When the shielding surface 331d of the impeller 3d rotates, the shielding surface 331d sequentially passes through the outward end portions of the plurality of sub-channels 220d, and the shielding surface 331d shields the end portions of the sub-channels 220d through which the sub-channels 220d pass, so that the sub-channels 220d cannot continuously inject water into the liquid collecting cavity 227d, in this way, the shielding surface 331d shields and opens the end portions of the sub-channels 220d, so that the water flow intermittently impacts the liquid collecting cavity 227d, and finally, the water flow output from the water outlet channel 224d has pulse feeling in the directions parallel to the water outlet channel 224d and perpendicular to the water outlet channel 224d, thereby forming the double massage feeling of pressing and kneading.

In an exemplary embodiment, as shown in fig. 19 and 21, the cover plate 23d is further provided with a guide post 232d. One end of the guiding column 232d is connected to the middle of the cover plate 23d and is located at one side of the cover plate 23d close to the water outlet channel 224 d. The other end of the guide post 232d extends into the outlet passage 224 d. The diameter of the portion of the guide post 232d extending into the outlet passage 224d is smaller than the inner diameter of the outlet passage 224 d. An annular gap is formed between the guiding column 232d and the water outlet passage 224 d.

The plurality of water streams respectively injected into the liquid collecting chamber 227d by the plurality of sub-channels 220d can move in the direction of the water outlet channel 224d under the guidance of the guide posts 232d, and at the same time, because the impeller 3d drives the water streams to rotate, the water streams can also rotate around the guide posts 232d to flow into the water outlet channel 224 d.
