Description

A magnetic levitation vibration type motion device for massager Technical Field

[0001] The present invention relates to the field of massagers, in particular to a magnetic suspension vibration type motion device for massagers. Background Art

[0002] As people's quality of life improves, more and more people begin to pay attention to their physical health and well-being. Massagers have become an indispensable item in people's daily lives. Existing massagers mostly use vibration-type motion devices.

[0003] For example, Patent No. CN102170604A provides a vibration-type motion device with a single-magnet magnetic circuit. In this single-magnet magnetic circuit, the magnetic circuit consists of a lower plate, magnet, middle ring, outer ring, and upper ring. Because the magnet is located far from the coil, it requires magnetic conductive components such as the lower plate, middle ring, outer ring, and upper ring to conduct magnetism. The use of multiple magnetic conductive components inevitably causes magnetic energy loss and low magnetic field utilization. Furthermore, the multiple magnetic conductive components inevitably increase the size of the overall device and increase manufacturing costs. Furthermore, the coil is made of a single aluminum die-cast part, which is inconvenient to process and has high manufacturing costs.

[0037] The following describes the technical solutions provided by various embodiments of the present application in conjunction with the accompanying drawings.

[0038] Referring to Figures 1 to 9, the present invention provides a magnetic levitation vibration-type motion device for a massager, comprising a magnet assembly 1, a tubular coil 2, and an upper cover 3 and a lower base 4 vertically spaced apart. The magnet assembly 1 and the tubular coil 2 are mounted between the upper cover 3 and the lower base 4. The magnet assembly 1 is fixed at the center of the lower end of the upper cover 3, and the tubular coil 2 is correspondingly fixed at the center of the upper end of the lower base 4. The upper cover 3 and the lower base 4 are identical in shape, both being rectangular and made of aluminum.

[0039] Referring to Figures 1, 4, and 5, magnet assembly 1 includes a magnetic base 11 made of a magnetically conductive material, such as iron. An annular magnetic gap 101 with an open bottom is defined within magnetic base 11. Multiple magnets 12 are mounted at equal intervals in a circular pattern on the inner wall of annular magnetic gap 101, distal from the center of magnetic base 11. These uniformly distributed magnets 12 ensure a stable magnetic field within annular magnetic gap 101.

[0040] Referring to Figure 4 , the tubular coil 2 is located below the magnet assembly 1 and is vertically movable relative to the magnet assembly 1. The upper end of the tubular coil 2 is positioned within the annular magnetic gap 101, while the magnet 12 corresponds to the upper end of the tubular coil 2 and is located outside the tubular coil 2. When alternating current is applied to the tubular coil 2, the Ampere force exerted on the energized conductor in the magnetic field causes the tubular coil 2 to reciprocate up and down relative to the magnet assembly 1, thereby driving the lower seat 4 to reciprocate vertically.

[0041] In some embodiments, as shown in Figures 4 to 7 , the magnetic base 11 includes an outer ring 111 and an inner ring 112 fixed to each other. For ease of processing, the outer ring 111 and the inner ring 112 are integrally formed. The magnet 12 is fixed to the inner circumferential wall of the outer ring 111, and an annular magnetic gap 101 is formed between the outer ring 111 and the inner ring 112.

[0042] In some embodiments, as shown in Figures 5 and 8 , the magnet member 12 is arcuate and has a first arcuate wall 121 and a second arcuate wall 122 that oppose each other. The first arcuate wall 121 is affixed to the inner wall of the annular magnetic gap 101, perhaps by gluing. The second arcuate wall 122 faces the outer wall of the tubular coil 2. The magnet member 12 is a permanent magnet, with the first arcuate wall 121 at one end being the south pole and the second arcuate wall 122 at one end being the north pole.

[0043] In some embodiments, as shown in Figures 1, 3, and 9, the tubular coil 2 includes an annular aluminum sheet 21 formed by bending a single aluminum sheet. A coil 22 is wound around the outer circumferential wall of the annular aluminum sheet 21, with the coil 22 partially positioned within the annular magnetic gap 101. The center of the lower base 4 is bent toward the upper cover 3 to form a connecting flange 401. A connecting portion 211 is retained at the lower end of the annular aluminum sheet 21, which is adhered to the connecting flange 401. This structure allows for easy manufacturing and processing of the tubular coil 2, resulting in low manufacturing costs, and a secure connection between the tubular coil 2 and the lower base 4.

[0044] In some embodiments, as shown in Figures 3 and 4 , the magnetic base 11 is fixedly connected to the upper cover 3 via multiple screws. The upper cover 3 is provided with multiple connection holes 301 at equal intervals along the circumference. The magnetic base 11 is provided with multiple threaded holes 113, each corresponding to each of the connection holes 301. Screws pass through the connection holes 301 and are threadedly connected to the corresponding threaded holes 113. This structure provides a secure connection between the magnetic base 11 and the upper cover.

[0045] In some embodiments, as shown in Figures 1 to 3, a buffer assembly 5 is symmetrically installed between the upper cover 3 and the lower seat 4. The buffer assembly 5 includes upper spring seats 51 symmetrically arranged on both sides of the middle of the upper cover 3 and lower spring seats 52 symmetrically arranged on the lower seat 4 and corresponding to the upper spring seats 51. A buffer spring 53 is installed between the upper spring seat 51 and the lower spring seat 52. The buffer assembly can provide a good buffering effect and a more stable structure.

[0046] In a preferred embodiment, as shown in Figures 1 to 3, multiple guide assemblies 6 are installed between the upper cover 3 and the lower seat 4. The guide assemblies 6 include guide rods 61 installed at the four corners of the upper cover 3, and guide sleeves 62 installed at the four corners of the lower seat 4 to cooperate with the guide rods 61. The provision of the guide assemblies 6 can guide the movement of the lower seat 4, making the movement direction more precise and the structure more stable.

[0047] The same and similar parts between the various embodiments in this specification can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0048] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
