Description

Technical Field

[0001] This utility model belongs to the field of massage instrument technology, and specifically refers to a massage head structure. Background Technology

[0002] Massage devices are becoming increasingly common health care equipment in modern people's daily lives, used to relieve muscle fatigue, promote blood circulation, and improve physical health. Massage devices typically have multiple massage heads, which are driven by a motor to rotate. The surface of each massage head has multiple massage protrusions that, as the head rotates, produce a massage effect similar to hand kneading.

[0003] In existing technologies, the massage protrusions on massage heads are mostly integrally molded, meaning that the height of the massage protrusions is relatively fixed. No matter whether the massage head rotates clockwise or counterclockwise, the height of the massage head will not change, resulting in a relatively simple massage effect that cannot meet the increasingly diverse massage needs. Utility Model Content

[0004] The main purpose of this invention is to provide a massage head structure that solves the problems existing in the prior art and can provide different massage effects when the massage head rotates in different directions.

[0005] To achieve the above objectives, the solution of this utility model is: A massage head structure includes a massage head body, a track seat, and a plurality of massage protrusions; the massage protrusions include at least one movable protrusion separately designed from the massage head body; the massage head body covers the upper surface of the track seat; the upper surface of the track seat is provided with an arc-shaped guide rail corresponding to the number of movable protrusions, the arc-shaped guide rail having a gradually increasing or decreasing height change trend; an arc-shaped hole matching the shape of the arc-shaped guide rail is provided through the upper and lower surfaces of the massage head body, the arc-shaped hole exhibiting a height change trend synchronized with the corresponding arc-shaped guide rail; the movable protrusions are slidably fitted on the upper surface of the massage head body, and their lower ends are provided with guide rods passing through the arc-shaped holes and movably fitted on the arc-shaped guide rails.

[0006] The upper surface of the massage head body is recessed to form a guide groove that changes in height synchronously with the arc-shaped hole, and the movable protrusion slides and engages within the guide groove.

[0007] The lower end of the guide rod is provided with a through hole running from left to right, and a pin is installed in the through hole; a relief groove is formed between the two sides of the arc-shaped guide rail; the lower end of the guide rod is movably fitted in the relief groove, and the pin is slidably fitted on the upper surface of the arc-shaped guide rail, and the upper surface of the arc-shaped guide rail and the lower surfaces of the two side walls of the arc-shaped hole clamp the pin.

[0008] Preferably, flanges are provided on both sides of the arc-shaped guide rail to restrict the axial movement of the pin.

[0009] The track base is provided with mounting holes through which the motor's shaft passes.

[0010] The massage head body and the track seat are assembled by screw locking.

[0011] The massage protrusions also include a fixed protrusion integrally formed with the massage head body, the fixed protrusion being disposed on the upper surface of the massage head body. Alternatively, all the massage protrusions are movable protrusions, and there are two movable protrusions, the height variation trends of the arc-shaped guide rails corresponding to the two movable protrusions being opposite along the same circumferential direction. Or, all the massage protrusions are movable protrusions, and there are two movable protrusions, the height variation trends of the arc-shaped guide rails corresponding to the two movable protrusions being the same along the same circumferential direction.

[0012] After adopting the above technical solution, the present invention has the following technical effects: This invention utilizes a track seat to form an arc-shaped guide rail within the massage head body, allowing the movable protrusions to slide and engage. The two ends of the arc-shaped guide rail have different heights. As the massage head rotates clockwise or counterclockwise, the movable protrusions, upon contact with the human body, experience a reaction force and move along the direction of the arc-shaped guide rail / arc-shaped hole from one end to the other. At different ends, the height of the top of the movable protrusion relative to the massage head body is different, thus providing different massage effects and enriching the user's massage experience.

[0021] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0022] refer to Figures 1 to 7 As shown, this utility model discloses a massage head structure, including a massage head body 1, a track seat 2, and several massage protrusions; The massage protrusion includes at least one movable protrusion 3 that is separately designed from the massage head body 1; The massage head body 1 covers the upper surface of the track seat 2; the upper surface of the track seat 2 is provided with an arc-shaped guide rail 21 corresponding to the number of movable protrusions 3. The arc-shaped guide rail 21 has a gradually increasing or gradually decreasing height trend, that is, the two ends of the arc-shaped guide rail 21 are not consistent in height and there is a smooth transition between the two ends. An arc-shaped hole 11 matching the shape of the arc-shaped guide rail 21 is provided through the upper and lower surfaces of the massage head body 1. The arc-shaped hole 11 exhibits a height change trend that is synchronized with the corresponding arc-shaped guide rail 21. The movable protrusion 3 slides on the upper surface of the massage head body 1, and its lower end is provided with a guide rod 31 that passes through the arc-shaped hole 11 and is movably fitted on the arc-shaped guide rail 21.

[0023] Through the above solution, this utility model utilizes the track seat 2 to form an arc-shaped guide rail 21 within the massage head body 1 for the movable protrusion 3 to slide and engage. The two ends of the arc-shaped guide rail 21 have different heights. During the clockwise or counterclockwise rotation of the massage head, the movable protrusion 3, after being subjected to a reaction force due to its contact with the human body, will move from one end to the other along the direction of the arc-shaped guide rail 21 / arc-shaped hole 11. At different ends, the top of the movable protrusion 3 has a different height relative to the massage head body 1, thereby providing different massage effects and enriching the user's massage experience.

[0024] refer to Figures 1 to 3 The first embodiment of the present invention is shown in the figure.

[0025] The upper surface of the massage head body 1 is recessed to form a guide groove 12 that has a synchronous height change trend with the arc-shaped hole 11. The movable protrusion 3 slides in the guide groove 12 to achieve limiting and guiding during sliding.

[0026] The lower end of the guide rod 31 is provided with a through hole 32 that runs from left to right, and a pin 4 is installed in the through hole 32; a relief groove 22 is formed between the two sides of the arc-shaped guide rail 21; the lower end of the guide rod 31 is movably fitted in the relief groove 22, and the pin 4 is slidably fitted on the upper surface of the arc-shaped guide rail 21, and the upper surface of the arc-shaped guide rail 21 and the lower surfaces of the two side walls of the arc-shaped hole 11 clamp the pin 4.

[0027] Furthermore, flanges 23 are provided on both sides of the aforementioned arc-shaped guide rail 21 to restrict the axial movement of the pin 4 and prevent the pin 4 from coming out of the through hole 32. Thus, the pin 4 only needs to pass through the guide rod 31 without being fixed, and the pin 4 can roll within the guide rod 31, which also reduces the friction when it slides on the arc-shaped guide rail 21.

[0028] The aforementioned track base 2 is provided with a mounting hole 24 through which the motor shaft passes. After passing through the mounting hole 24, the motor shaft is connected and fixed to the lower surface of the massage head body 1, thereby driving the massage head.

[0029] The massage head body 1 and the track seat 2 are assembled and fixed by screw locking.

[0030] In the first embodiment, the massage protrusion further includes a fixing protrusion 13 integrally formed with the massage head body 1, and the fixing protrusion 13 is disposed on the upper surface of the massage head body 1.

[0031] refer to Figure 4 , 5 As shown, a second embodiment of the present invention is illustrated.

[0032] The second embodiment employs most of the same technical means as the first embodiment. The main difference lies in that the massage protrusions in the second embodiment are all movable protrusions 3, and there are two movable protrusions 3. The height variation trends of the arc-shaped guide rails 21 corresponding to the two movable protrusions 3 are opposite along the same circumferential direction. Therefore, during the clockwise or counterclockwise rotation of the massage head, the two movable protrusions 3 exhibit a "one high, one low" effect, and the two movable protrusions 3 always have a height difference.

[0033] refer to Figure 6 , 7 As shown, a third embodiment of the present invention is illustrated.

[0034] The third embodiment employs most of the same technical means as the second embodiment. Its main difference lies in that the height variation trend of the arc-shaped guide rails 21 corresponding to the two movable protrusions 3 is the same along the same circumferential direction. Therefore, it is possible to achieve the effect of "equal height and level" for the two movable protrusions 3 during clockwise or counterclockwise rotation of the massage head, ensuring that the two movable protrusions 3 are always at the same height.

[0035] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
