Description

Technical Field

[0001] This invention belongs to the field of beauty equipment technology, and particularly relates to a spray mechanism and beauty device. Background Technology

[0002] Facial steamers or oxygen infusion devices often have nozzles with a narrow spray angle. The nozzles are either fixed to the product or only move slightly up and down, resulting in incomplete mist coverage. Users must constantly move the device or adjust their facial posture to meet the spray, significantly reducing user comfort and ease of use. For example, Chinese invention patent CN205007246U discloses an aromatherapy whitening facial steamer with a fixed steam nozzle on the top cover. Users must rotate the entire device or adjust their facial posture to meet the spray, leading to a poor user experience. Summary of the Invention

[0003] In view of the above-mentioned problems existing in the prior art, the purpose of the present invention is to provide a spray mechanism and beauty device with a large spray range and a good user experience.

[0004] The technical solution adopted in this embodiment of the invention is a spraying mechanism, comprising: a retainer assembly including an elastic member, the retainer assembly having an inner spherical surface; a nozzle assembly having an outer spherical surface adapted to the inner spherical surface, the nozzle assembly being fixedly connected to the elastic member so that the outer spherical surface fits against the inner spherical surface; and a drive assembly being kinetically connected to the nozzle assembly for driving the nozzle assembly to perform a conical pendulum motion relative to the retainer assembly. In this embodiment of the invention, the nozzle assembly is mounted on the retainer assembly via the elastic member, and the outer spherical surface of the nozzle assembly fits against the inner spherical surface of the retainer assembly. The elastic member can prevent the nozzle assembly from rotating around its axis, but can achieve a 360° conical pendulum motion through the cooperation of the inner and outer spherical surfaces, increasing the spray range and improving the user experience.

[0005] In an optional embodiment, the nozzle assembly includes: a nozzle holder having a first end and a second end opposite to each other; the outer peripheral surface of the first end forms an outer spherical surface; the end face of the first end is recessed inward to form a chamber; the nozzle holder has a first mounting hole and a second mounting hole respectively communicating with the chamber; the first mounting hole is arranged along the center line of the nozzle holder; and the axis of the second mounting hole intersects the axis of the first mounting hole; an air nozzle is disposed in the first mounting hole; a water nozzle is disposed in the second mounting hole; and a swing sleeve is connected to the second end of the nozzle holder, the swing sleeve being used for transmission connection with the drive assembly. This nozzle assembly has a reasonable structure, is easy to assemble, and can better form a spray.

[0006] In an optional embodiment, the retainer assembly further includes: a first frame, the inner spherical surface being formed on the first frame, the first frame having a first through hole extending to the inner spherical surface, the first through hole communicating with the spherical cavity enclosed by the inner spherical surface, so that the nozzle assembly sprays outward through the first through hole; a second frame connected to the first frame, the second frame having a second through hole, so that the nozzle assembly is connected to the drive assembly through the second through hole; the elastic component includes an elastic sleeve, the outer peripheral wall of the elastic sleeve being fixed between the first frame and the second frame, and the inner peripheral wall of the elastic sleeve being fixedly connected to the nozzle holder. The retainer assembly of this embodiment is simple to assemble, allowing the nozzle assembly to rotate flexibly and smoothly.

[0007] In an optional embodiment, at least one annular fold is provided between the inner peripheral wall and the outer peripheral wall of the elastic sleeve, so that the annular fold can be folded or unfolded when the inner peripheral wall moves radially relative to the outer peripheral wall. In this embodiment of the invention, the elastic sleeve is provided with an annular fold, which can maintain a stable fit between the inner and outer spherical surfaces and fold or unfold with the swing of the nozzle assembly, thereby reducing the resistance of the nozzle assembly swing.

[0008] In an optional embodiment, the inner peripheral wall of the elastic sleeve has a ring of protrusions for fixed connection with the nozzle holder. Multiple notches are spaced apart on the protrusions, interrupting the protrusions circumferentially. The nozzle holder has a fixing groove surrounding its outer wall, with multiple limiting strips spaced apart within the fixing groove to interrupt the fixing groove circumferentially. When the nozzle assembly is mounted on the retainer assembly, the protrusions are embedded in the fixing groove, and the limiting strips are embedded in the notches, thus fixing the nozzle holder to the elastic sleeve. In this embodiment, the protrusions on the elastic sleeve for connection with the nozzle assembly have notches circumferentially, and the corresponding fixing grooves on the nozzle assembly are not connected circumferentially, thereby fixing the nozzle holder and preventing it from rotating.

[0009] The retainer assembly further includes: a first frame, the inner spherical surface being formed on the first frame, the first frame having a first through hole extending to the inner spherical surface, the first through hole communicating with the spherical cavity enclosed by the inner spherical surface so that the nozzle assembly sprays outward through the first through hole; the elastic component includes a plurality of springs, one end of each of the plurality of springs being fixed to the nozzle holder, and the other end of each of the plurality of springs being fixed to the first frame.

[0010] In an optional embodiment, the angle between the axis of the first mounting hole and the axis of the second mounting hole is 30°-60°. In this embodiment of the invention, the water nozzle and the air nozzle are assembled at this angle to better form a spray.

[0011] In an optional embodiment, the second end of the nozzle holder has a notch for allowing the air intake pipe connected to the jet nozzle to pass through radially. In this embodiment of the invention, the air intake pipe is connected to the jet nozzle radially to avoid interfering with the connection between the second end of the nozzle holder and the drive device.

[0012] In an optional embodiment, the swing sleeve has an inwardly recessed swing hole with a concave spherical bottom. The driving assembly includes an eccentric wheel, which comprises a wheel body and a driving rod eccentrically mounted on the wheel body and protruding towards the swing sleeve. The driving rod is disposed within the swing hole so that when the eccentric wheel rotates, the driving rod drives the nozzle assembly to swing in a circular motion. In this embodiment of the invention, the nozzle assembly is directly driven to swing in a circular motion via the eccentric wheel, resulting in a simple structure and easy assembly.

[0013] In an optional embodiment, the drive assembly further includes a motor, and the eccentric wheel is connected to the output shaft of the motor. In this embodiment of the invention, a motor is directly connected to a cam, resulting in a simple structure and easy assembly.

[0014] Secondly, embodiments of the present invention provide a beauty device, which includes the spray mechanism described in any of the above embodiments.

[0015] Compared with the prior art, the beneficial effect of the spray mechanism of the present invention is that the nozzle assembly in the spray mechanism of the present invention is assembled on the retainer assembly by an elastic member, and the outer spherical surface of the nozzle assembly is in contact with the inner spherical surface of the retainer assembly. The elastic member can prevent the nozzle assembly from rotating around the axis, but can achieve 360° conical pendulum motion through the cooperation of the inner and outer spherical surfaces, thereby increasing the spray range and improving the user experience.

[0016] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit the invention.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0034] This invention provides a spray mechanism that can be applied to beauty products such as facial steamers and oxygen infusion devices. See also... Figures 1 to 12 The spray mechanism includes a cage assembly 26, a nozzle assembly 21, and a drive assembly 25. The cage assembly 26 includes an elastic member and has an inner spherical surface 15. The nozzle assembly 21 has an outer spherical surface 16 adapted to the inner spherical surface 15. The elastic member is sleeved on the outside of the nozzle assembly 21 so that the outer spherical surface 16 fits against the inner spherical surface 15. The drive assembly 25 is drively connected to the nozzle assembly 21 and drives the nozzle assembly 21 to oscillate relative to the cage assembly 26 in a conical pendulum motion.

[0035] In this embodiment of the invention, the nozzle assembly 21 is mounted on the retainer assembly 26 via an elastic component, such that the outer spherical surface 16 of the nozzle assembly 21 is in contact with the inner spherical surface 15 of the retainer assembly 26. The elastic component prevents the nozzle assembly 21 from rotating around its axis, but allows for a 360° conical pendulum motion through the cooperation of the inner spherical surface 15 and the outer spherical surface 16. This increases the spray range, ensuring that the sprayed mist is applied to the skin from all directions, greatly enhancing the user experience and improving ease of use. The spray effect can be seen in [reference needed]. Figure 13 .

[0036] See Figure 3 In some embodiments, the retainer assembly 26 further includes a first frame 12 and a second frame 7. The first frame 12 has a first through hole 121, and an inner spherical surface 15 is formed on the first frame 12, forming a spherical cavity. The first through hole 121 communicates with the spherical cavity so that the nozzle assembly 21 sprays through the first through hole 121. The second frame 7 is connected to the first frame 12 and is annular to form a second through hole 71. The nozzle assembly 21 is connected to the drive assembly 25 through the second through hole 71. The elastic member includes an elastic sleeve 8, the outer peripheral wall of which is fixed between the first frame 12 and the second frame 7, and the inner peripheral wall of which is fixedly connected to the nozzle assembly 21. The first frame 12 and the second frame 7 clamp and fix the outer peripheral wall of the elastic sleeve 8, realizing the assembly of the nozzle assembly 21 fixed to the inner peripheral wall of the elastic sleeve 8 and the retainer assembly 26. Under the action of the elastic sleeve 8, the outer spherical surface 16 on the nozzle assembly 21 fits against the inner spherical surface 15 on the first frame 12. The cooperation between the inner spherical surface 15 and the outer spherical surface 16 allows the nozzle assembly 21 to swing relative to the retainer assembly 26 in any direction. The deformation of the elastic sleeve 8 allows the relative movement of its inner peripheral wall to the outer peripheral wall, satisfying the displacement required for the swing of the nozzle assembly 21 fixed to the inner peripheral wall. The retainer assembly 26 of this embodiment is simple to assemble, making the nozzle assembly 21 rotate flexibly and smoothly.

[0037] In some embodiments, see Figure 2The elastic sleeve 8 has at least one annular fold 17 between its inner and outer peripheral walls, allowing the annular fold 17 to fold or unfold when the inner peripheral wall moves radially relative to the outer peripheral wall. The annular fold 17 increases the displacement of the inner peripheral wall relative to the outer peripheral wall of the elastic sleeve 8 by folding or unfolding, and has a strong elastic force to keep the outer spherical surface 16 of the nozzle assembly 21 in contact with the inner spherical surface 15 of the first frame 12, ensuring the smoothness of the nozzle assembly 21's swing. In this embodiment of the invention, the elastic sleeve 8 is provided with an annular fold 17, which can maintain a stable contact between the inner spherical surface 15 and the outer spherical surface 16, and fold or unfold with the swing of the nozzle assembly 21, reducing the resistance to the swing of the nozzle assembly 21.

[0038] In some embodiments, the elastic sleeve 8 can be made of materials such as soft plastic, rubber, and silicone. Soft plastics include PP (polypropylene), PE (polyethylene), TPU (thermoplastic polyurethane elastomer), TPE (thermoplastic rubber), and soft PVC.

[0039] In some embodiments, such as Figure 9 As shown, the inner circumferential wall of the elastic sleeve 8 has a ring of protrusions 81 for fixed connection with the nozzle assembly 21. The protrusions 81 have notches 82 that interrupt the protrusions 81 circumferentially. The nozzle assembly 21 has a fixing groove 91 corresponding to the protrusions 81, and multiple limiting strips 92 are spaced apart within the fixing groove 91 (see...). Figure 9 and Figure 10 The nozzle assembly 21 is mounted on the retainer assembly 26, with the protrusion 81 embedded in the retaining groove 91 and the limiting strip 92 embedded in the notch 82, thus fixing the nozzle assembly 21 to the elastic sleeve 8. In this embodiment of the invention, the protrusion 81 of the elastic sleeve 8 used to connect with the nozzle assembly 21 has a notch 82 in the circumferential direction, and the corresponding retaining groove 91 on the nozzle assembly 21 is provided with a limiting strip 92, so that the retaining groove 91 is not connected in the circumferential direction. The notch 82 on the protrusion 81 cooperates with the limiting strip 92 in the retaining groove 91 to fix the nozzle assembly 21 while preventing the nozzle assembly 21 from rotating.

[0040] In some embodiments, see Figure 3The nozzle assembly 21 includes a nozzle holder 9, a water nozzle 10, an air nozzle 11, and a swing sleeve 4. The nozzle holder 9 has a first end and a second end opposite to each other. The outer circumferential surface of the first end forms an outer spherical surface 16, and a cavity is formed by an inward recess from the end face of the first end. A fixing groove 91 is arranged around the outer circumferential surface of the nozzle holder 9. The nozzle holder 9 has a first mounting hole and a second mounting hole respectively communicating with the cavity. The first mounting hole is arranged along the centerline of the nozzle holder 9 (i.e., the axis of the first mounting hole is collinear with the axis of the outer spherical surface), and the axis of the second mounting hole intersects the axis of the first mounting hole, forming a certain angle. The air nozzle 11 is installed in the first mounting hole, and the water nozzle 10 is installed in the second mounting hole. The swing sleeve 4 is connected to the second end of the nozzle holder 9 and is used for transmission connection with the drive assembly 25. The water nozzle 10 and the air nozzle 11, respectively installed in the first and second mounting holes, are arranged intersectingly. The high-speed airflow ejected from the air nozzle 11 disperses the water droplets flowing from the water nozzle 10, forming a spray phenomenon and achieving the spraying purpose. The sprayed mist particles are smaller, making it easier to penetrate the inner layer of the skin for hydration. The nozzle holder 9 is provided with a first mounting hole and a second mounting hole, which can be used to quickly assemble the air nozzle 11 and the water nozzle 10 for easy assembly.

[0041] In some embodiments, see Figure 6 and Figure 7 The nozzle 11 has a micro-pore constriction at its nozzle 24, with a diameter of 0.3 mm. The gas supplied to the nozzle 11 through the air inlet pipe 5 experiences increased airflow velocity at the nozzle 24, reaching supersonic speeds. This high-speed airflow creates a vacuum negative pressure zone 23 around the water nozzle 22 of the spray nozzle 10. Under atmospheric pressure, water from the water tank in the beauty equipment is drawn upwards by this negative pressure into the spray nozzle 10 and flows out from the nozzle 22. The constriction of the nozzle 24 can be calculated using Bernoulli's equation. The diameter of the water nozzle 22 of the spray nozzle 10 can be 0.25 mm. The spray nozzle 10 is connected to the water tank via the water inlet pipe 6. A concave chamber is provided at the first end of the nozzle holder 9, where the nozzle 11 is located, facilitating the generation of negative pressure near the water nozzle 22 of the spray nozzle 10.

[0042] The spray mechanism of this embodiment of the invention also includes an air supply unit, and the jet nozzle 11 is connected to the air supply unit through the air inlet pipe 5.

[0043] In some embodiments, see Figure 5 The angle between the axis of the first mounting hole and the axis of the second mounting hole can be 30°-60°. In this embodiment of the invention, the water nozzle 10 and the air nozzle 11 are assembled at this angle, which can better atomize the water flow and form a spray.

[0044] In some embodiments, see Figure 4The second end of the nozzle holder 9 has a notch for the air intake pipe 5, which is connected to the jet nozzle 11, to pass through radially along the nozzle holder 9. In this embodiment of the invention, the air intake pipe 5 is connected to the jet nozzle 11 radially to avoid affecting the connection between the second end of the nozzle holder 9 and the drive device.

[0045] In some embodiments, see Figure 5 The swing sleeve 4 has a recessed swing hole 13, the bottom of which is a concave spherical surface. The drive assembly 25 includes an eccentric wheel 3, which includes a wheel body and a drive rod 31 eccentrically mounted on the wheel body and protruding towards the swing sleeve 4. The end of the drive rod 31 is a convex spherical surface. The drive rod 31 extends into the swing hole 13 so that when the eccentric wheel 3 rotates, the drive rod 31 drives the nozzle assembly 21 to swing in a ring. In this embodiment of the invention, the eccentric wheel 3 directly drives the nozzle assembly 21 to swing in a ring, which is simple in structure and easy to assemble.

[0046] In some embodiments, see Figure 6 The drive assembly 25 also includes a motor 2, and the wheel body of the eccentric wheel 3 is connected to the output shaft of the motor 2. In this embodiment of the invention, the motor 2 is directly connected to the eccentric wheel 3, which is simple in structure and easy to assemble.

[0047] like Figure 11 and Figure 12 As shown, in addition to the elastic sleeve 8, the elastic component can also be multiple springs 27 as an alternative. One end of each spring 27 is fixed to the nozzle holder 9, and the other end of each spring 27 is fixed to the first frame 12. When the nozzle assembly 21 moves in a conical pendulum motion, the springs 27 deform under force. Due to the positioning effect of the springs 27, the circumferential rotation direction of the nozzle assembly 21 is restricted, thus achieving the purpose that the nozzle assembly 21 can swing but cannot rotate.

[0048] Specifically, continue to combine Figure 11 and Figure 12 The nozzle holder 9 protrudes outward to form a first spring seat 93. The first frame 12 protrudes outward on the side of its periphery facing the nozzle holder 9 to form a second spring seat 122. The two ends of the spring 27 are respectively fixed to the first spring seat 93 and the second spring seat 122.

[0049] It is understandable that when the elastic sleeve 8 is replaced by the spring 27, the structures of all other components can be exactly the same, except that the second frame 7 is omitted and the structures of the nozzle frame 9 and the spring 27 and the nozzle frame 9 and the elastic sleeve 8 are different.

[0050] See Figures 1 to 7Taking the elastic sleeve 8 as an example, the assembly process of the spray mechanism in this embodiment of the invention is described as follows: An air inlet pipe 5 is inserted into the tail end of the air nozzle 11, and a water inlet pipe 6 is inserted into the tail end of the water nozzle 10. Then, the air nozzle 11 and the water nozzle 10 are respectively assembled into the first and second assembly holes on the nozzle holder 9. The axes of the air nozzle 11 and the water nozzle 10 form an angle θ (see...). Figure 5 Finally, the swing sleeve 4 is assembled onto the nozzle holder 9 and secured with screws, completing the assembly of the nozzle assembly 21.

[0051] The nozzle assembly 21 is fitted into the elastic sleeve 8, and the inner peripheral wall of the elastic sleeve 8 is embedded in the fixing groove 91 of the nozzle holder 9. Then, the elastic sleeve 8 is clamped by the second frame 7 and the first frame 12. At this time, the outer spherical surface 16 of the nozzle assembly 21 coincides with the inner spherical surface 15 of the retainer assembly 26. The inner spherical surface 15 can slide freely on the outer spherical surface 16 to swing freely, that is, to swing in a ring at an angle α with the swing center 18 (see...). Figure 5 ).

[0052] Motor 2 is installed into motor sleeve 1, and eccentric wheel 3 is connected to motor 2 to form a motor assembly.

[0053] The drive rod 31 of the eccentric wheel 3 is aligned with the swing hole 13 of the swing sleeve 4, and the motor assembly is installed into the nozzle assembly 21. Driven by the eccentric wheel 3, the nozzle assembly 21 tilts to the side. The angle α between the center line of the nozzle assembly 21 and the center line of the motor assembly 2 is the swing angle 19. At this time, the universal sliding assembly of the nozzle assembly 21 is completed.

[0054] When the motor 2 rotates, the eccentric wheel 3 acts on the nozzle assembly 21, and the nozzle assembly 21 makes a 360° circular swing motion around the swing center 18 with a swing angle 19 of a, so as to achieve the purpose of universal sliding and 360° swing of the assembly.

[0055] The annular fold 17 of the elastic sleeve 8 forms a deformation zone. When the motor assembly drives the nozzle assembly 21 to swing, the deformation zone of the elastic sleeve 8 will deform under force. Due to the fixing effect of the elastic sleeve 8, the direction of circumferential rotation of the nozzle assembly 21 is restricted. This can both fix the nozzle assembly 21 and prevent the nozzle assembly 21 from rotating in the circumferential direction. See [reference needed] Figure 8 .

[0056] This invention utilizes hemispherical connection positioning technology to enable the nozzle assembly 21 to slide in all directions. Taking advantage of the principle that the center position of the spheres remains unchanged during sliding between spheres, a motor drives the nozzle assembly 21 to oscillate. Furthermore, a soft rubber connection anti-rotation positioning technology is employed. Utilizing the principle that the soft rubber material 8 is easily deformed under stress, a wave-like annular fold 17 is designed at a local location on the elastic sleeve 8. When the elastic sleeve 8 is fitted with the nozzle assembly 21, the elastic sleeve 8 restricts the nozzle assembly 21 from rotating in a circular motion, but does not restrict its annular oscillation. Additionally, the cross-assembly of nozzles creates a vacuum negative pressure zone, using high-speed airflow to disperse water and create a spray phenomenon. This invention's spray mechanism achieves a 360° annular oscillating spray function, spraying the skin from all directions, greatly enhancing the user's experience and improving ease of use. Moreover, its structure is simple and ingenious, occupying little space, low in cost, and easy to assemble. This invention provides a beauty device, including the spray mechanism of this embodiment.

[0057] The above description is intended to be illustrative and not restrictive. Those skilled in the art can make variations, modifications, substitutions, and alterations to the above embodiments within the scope of this disclosure. Moreover, the above examples (or one or more of them) can be used in combination with each other, and these embodiments can be combined with each other in various combinations or arrangements.
