Description

Technical Field

[0001] The utility model relates to the technical field of massagers, in particular to a guide sleeve structure and a massager. Background Art

[0002] Head massagers typically use an eccentric cam or hinged mechanism to drive the massage claws. Because the massage claws are mobile, while the massager's housing is relatively fixed, the housing must have a space to accommodate the movement of the rocker. As the massage claws massage the user's head, the user may sweat or their hair may coat the massage area with massage fluid. This fluid can easily enter the massager, contaminating it and making it difficult to clean, affecting subsequent hygiene.

[0003] To address this issue, patent publication number CN216021987U discloses a massager that features an intermediate guide sleeve designed around the rocker mechanism. The sleeve is mounted on the rocker, and a retaining spring secures a silicone sleeve to the outer wall of the sleeve. The sleeve's outer periphery is sealed against the periphery of the housing's mounting hole. However, there's no strict seal between the sleeve's outer wall and the sleeve's inner ring. This makes it prone to leakage at the connection between the sleeve and the intermediate guide sleeve during use, when the silicone sleeve deforms under force. This allows external contaminants to easily enter the housing, resulting in poor overall waterproofing. Utility Model Content

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. In the following, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, unless otherwise specified, "multiple" means two or more.

[0026] Reference Figures 1 to 3The massager shown includes a guide sleeve structure, which includes a guide sleeve body 10, a silicone sleeve 20 and a guide sleeve buckle 30. A buckle ring 11 is provided on one end of the guide sleeve body 10, and a mounting ring platform 12 is provided on the outer periphery of the guide sleeve body 10; the silicone sleeve 20 is movably sleeved on the guide sleeve body 10; the guide sleeve buckle 30 is sleeved on the guide sleeve body 10, and the inner ring of the guide sleeve buckle 30 is provided with a buckle platform 31 that cooperates with the buckle ring 11; the corresponding end of the guide sleeve buckle 30 can press the silicone sleeve 20 against the mounting ring platform 12.

[0027] The guide sleeve body 10 is mounted on the rocker, while the outer edge of the silicone sleeve 20 is buckled onto the opening of the housing, thus providing a seal. In the above embodiment, the mounting ring 12 not only constrains the inner ring structure of the silicone sleeve 20, but also cooperates with the guide sleeve buckle 30 to abut the portion of the silicone sleeve 20 near the center area, making the connection of the entire silicone sleeve 20 more stable.

[0028] In some possible implementations, in order to better seal, the silicone sleeve 20 includes an inner ring portion 21, a deformable folded portion 22, and an outer ring sealing portion 23, which are arranged in sequence from the inside to the outside. The inner ring portion 21 is sleeved on the guide sleeve body 10, and the guide sleeve buckle 30 can press the inner ring portion 21 against the mounting ring platform 12. Among them, the deformable folded portion 22 is folded back and forth in a serpentine shape as a whole. The purpose of this is to ensure that the deformable folded portion 22 can follow the inner ring portion 21 in the later stage when the guide sleeve body 10 moves, so that there is enough area for deformation and bending, which can ensure that the inner ring portion 21 reduces its own deformation and ensure the connection and sealing between the inner ring portion 21 and the guide sleeve body 10.

[0029] In order to improve the sealing performance of the connection between the inner ring portion 21 and the guide sleeve body 10, in an improved embodiment of the present application, a limiting ring groove 13 is provided on the side of the mounting ring platform 12 close to the buckle ring 11. One end of the inner ring portion 21 is clamped in the limiting ring groove 13. The mounting ring platform 12 is provided with an abutting slope 14 on the outer ring of the opening of the limiting ring groove 13. The abutting slope 14 abuts against the side of the deformable folded portion 22, and the guide sleeve buckle 30 can simultaneously clamp the inner ring portion 21 and the deformable folded portion 22. The limiting ring groove 13 can clamp one end of the inner ring portion 21, preventing it from being affected by the deformation of the deformable folded portion 22 and undergoing excessive deformation. The design of the abutting slope 14 enables the guide sleeve buckle 30 to press the side of the deformable folded portion 22 close to the inner ring portion 21, thereby improving the sealing performance.

[0030] In the above-mentioned improved solution, in order to better restrain the inner ring portion 21, a V-shaped abutment groove 24 is provided between the inner ring portion 21 and the deformable folded portion 22. An abutment platform 32 is provided on the inner ring of one end of the guide sleeve buckle 30. An abutment edge 33 is provided on the outer side of the abutment platform 32 of the guide sleeve buckle 30. The abutment platform 32 can cooperate with and abut the inner ring portion 21, and the abutment edge 33 can extend into and abut the bottom of the V-shaped abutment groove 24. This design can use the abutment edge 33 to tighten the connection between the inner ring portion 21 and the deformable folded portion 22 against the abutment slope 14, thereby improving the protective capability.

[0031] In some possible implementations, in order to facilitate the installation of the outer ring sealing portion 23 in the installation hole of the housing, a buckle edge 25 is provided on the outer periphery of the outer ring sealing portion 23 .

[0032] In some possible implementations, in order to facilitate the matching installation of the guide sleeve body 10 and the guide sleeve ring buckle 30, a guide cone surface 15 is provided on the end face of the guide sleeve body 10 at one end of the buckle ring 11. This design is conducive to inserting the buckle ring 11 into the guide sleeve ring buckle 30.

[0033] See also Figure 2 and Figure 3 To facilitate the accommodation of the retaining ring platform 31, in one embodiment of the present application, the outer wall of one end of the guide sleeve body 10 is recessed to form a ramp annular groove 16. The buckle ring 11 forms the outward side of the ramp annular groove 16. The side of the ramp annular groove 16 away from the buckle ring 11 is provided with a mating slope 17. The inner side of the retaining ring platform 31 is provided with a guide surface 34 that cooperates with the mating slope 17. The retaining ring platform 31 is generally ratchet-shaped, which can effectively ensure a secure connection between the guide sleeve buckle 30 and the guide sleeve body 10 and prevent slippage.

[0034] In some possible implementations, to facilitate installation on the rocker, the guide sleeve body 10 is provided with a blind mounting hole 18 on one end thereof near the buckle ring 11. Furthermore, to facilitate installation, a chamfer is provided between the opening of the mounting hole 18 and the guide sleeve body 10.

[0035] The guide sleeve structure is provided with a mounting ring 12 on the outer periphery of the guide sleeve body 10, and the corresponding end of the guide sleeve buckle 30 is used to press the silicone sleeve 20 against the mounting ring 12. In addition to limiting the deformation of the inner ring of the silicone sleeve 20, the design of the guide sleeve buckle 30 and the mounting ring 12 can also be used to limit the deformation of the silicone sleeve 20 near the inner ring. This can ensure a stable connection between the inner ring of the silicone sleeve 20 and the guide sleeve body 10, reduce the risk of leakage, and improve the sealing. Among them, a snap-fit ​​structure design is adopted between the guide sleeve buckle 30 and the guide sleeve body 10, which makes the assembly structure between the two simpler and improves the convenience of disassembly and assembly.

[0036] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present invention shall be covered by the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
