Description

Technical Field

[0001] The utility model relates to the technical field of massage devices, in particular to a massage device with adjustable massage distance. Background Art

[0002] There are various massage devices on the market, such as massage chairs, shoulder and neck massage devices, leg massage devices, etc. Among them, leg and foot massagers can eliminate fatigue, relax muscles and blood circulation, and relax the body and mind by massaging the legs and feet.

[0003] There are basically two types of existing leg massage devices: one is the air bag massage method, and the other is the mechanical pinching and rubbing method. The air bag massage method is to squeeze and massage the human calf by inflating and deflating the air bags installed on both sides of the calf. This method has a relatively poor user experience and a single massage technique. In the mechanical pinching and rubbing method, the distance between the two sides of the calf remains relatively unchanged, and it cannot be automatically adjusted according to the difference in the thickness of the user's calf. For consumers with thick legs, the massage intensity is too high, and for consumers with thin legs, the massage intensity may not be felt. Utility Model Content

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0039] like Figures 1 to 7 As shown, a massage device with adjustable massage distance of the utility model comprises a massage housing 1, a massage spindle 2, a massage component 3, a massage motor 4 and a distance adjustment component 5.

[0040] The massage spindle 2 is rotatably mounted on the massage housing 1. In this embodiment, the massage housing 1 is a leg massager as an example. The massage housing 1 has two massage areas 11. A group of massage components 3 is arranged in each massage area 11. Of course, only one massage area 11 may be arranged.

[0041] The massage component 3 includes a first massage structure 31 and a second massage structure 32. The first massage structure 31 and the second massage structure 32 are installed on the massage main shaft 2 at intervals, and the first massage structure 31 can be axially reciprocatingly slidably sleeved on the massage main shaft 2; a massage spacing H is formed between the first massage structure 31 and the second massage structure 32 for the user's legs and other parts to be inserted and placed.

[0042] The massage motor 4 drives the massage main shaft 2 to rotate. The massage motor 4 can also be installed in the massage housing 1, and can drive the massage main shaft 2 through the cooperation of the worm gear and the spur gear of the massage gear assembly 41.

[0043] When the massage main shaft 2 rotates, it drives the first massage structure 31 and the second massage structure 32 to perform massage movements, so as to perform kneading massage on the legs and other parts.

[0044] The spacing adjustment component 5 includes an adjustment motor 51 and a linear adjustment structure 52; the linear adjustment structure 52 connects the adjustment motor 51 and the first massage structure 31; in this embodiment, the linear adjustment structure 52 takes a screw mechanism 52a as an example, and the screw mechanism 52a includes a slider 521 and a screw 522 that cooperate with each other; the first massage structure 31 is connected to the slider 521; the adjustment motor 51 drives the screw 522 to rotate, and the rotation of the screw 522 drives the slider 521 and the first massage structure 31 to slide along the massage main axis 2.

[0045] Also see Figure 2 and Figure 3 In this embodiment, the massage component 3 and the linear adjustment structure 52 each have two groups, and are symmetrically arranged on both sides of the massage main shaft 2. The two first massage structures 31 are adjacently arranged in the middle of the massage main shaft 2, and the two second massage structures 32 are respectively arranged at both ends of the massage main shaft 2; the adjustment motor 51 is arranged corresponding to the middle of the massage main shaft 2, and the screw rods 522 of the two linear adjustment structures 52 can be connected as a whole to be driven by the adjustment motor 51 to rotate synchronously.

[0046] Thus, when the adjusting motor 51 drives the linear adjusting structure 52 to move, it will drive the two first massage structures 31 to slide back and forth along the axial direction of the massage main shaft 2, and can synchronously adjust the size of the massage spacing H of the massage components 3 on both sides, thereby being suitable for different users with different leg shapes to have a better massage effect and avoid the gap being too large to massage. At the same time, the adjusting motor 51 is used for electric adjustment, which is quick and convenient to use; specifically, it can be controlled by the corresponding control button 12 set on the massage housing 1.

[0047] See also Figure 4The spacing adjustment component 5 also includes an adjustment movement 53 and an adjustment gear set 54. The adjustment movement 53 can be fixed to the massage housing 1. The adjustment motor 51 is installed in the adjustment movement 53 to drive the screw rod 522 to rotate through the adjustment gear set 54.

[0048] like Figure 3 , Figure 6 and Figure 7 As shown, the first massage structure 31 includes a first massage arm 311 and a first eccentric wheel 312 ; the second massage structure 32 includes a second massage arm 321 and a second eccentric wheel 322 .

[0049] The first eccentric wheel 312 and the second eccentric wheel 322 are coaxially rotatably sleeved on the massage main shaft 2, and the first eccentric wheel 312 can be axially reciprocatingly slidably sleeved on the massage main shaft 2; the first massage arm 311 and the second massage arm 321 are eccentrically rotatably sleeved on the first eccentric wheel 312 and the second eccentric wheel 322, respectively. Therefore, when the massage main shaft 2 rotates, the first eccentric wheel 312 and the second eccentric wheel 322 are driven to rotate, and then the first massage arm 311 and the second massage arm 321 are linked to eccentrically swing, thereby forming a massage and kneading effect.

[0050] For example, in order to realize the reciprocating sliding effect of the first massage structure 31 on the massage main shaft 2, an axially penetrating sliding through hole 3121 may be provided on the first eccentric wheel 312, and the outer side of the sliding through hole 3121 is also connected to an axially penetrating limiting groove 3122; and a limiting portion 211 radially protrudes on the massage main shaft 2 in the sliding area of ​​the first eccentric wheel 312, and the limiting portion 211 is extended into the limiting groove 3122, and moves axially in the limiting groove 3122 with the axial sliding of the first eccentric wheel 312, so that the first massage structure 31 can realize reciprocating movement through the sliding through hole 3121; and when the massage main shaft 2 rotates, the limiting portion 211 circumferentially abuts against the limiting groove 3122, which can drive the first eccentric wheel 312 to rotate synchronously, thereby realizing the eccentric swing of the first massage arm 311.

[0051] Specifically, in order to facilitate assembly and installation, a radially through pin hole 22 is provided on the massage main shaft 2 in the sliding area of ​​the first eccentric wheel 312. In this embodiment, two spaced-apart pin holes 22 are provided, and a limit pin 21 is passed through each pin hole 22. Both ends of the limit pin 21 protrude from the outer wall of the massage main shaft 2 to form the limit portion 211; and there are two limit grooves 3122, which are symmetrically arranged on both sides of the sliding through hole 3121, and the limit portions 211 at both ends of the limit pin 21 are respectively extended into the two limit grooves 3122.

[0052] Another example Figure 3 and Figure 6As shown, the massage main shaft 2 and the screw rod 522 are distributed in parallel inside and outside to avoid mutual interference; an inner sleeve hole 5211 is formed on the inner side of the slider 521, and the first eccentric wheel 312 connected to the first massage structure 31 is sleeved in the inner sleeve hole 5211. A groove 3123 can be set on the first eccentric wheel 312, and an embedded block 5212 is set in the inner sleeve hole 5211. The embedded block 5212 is embedded in the groove 3123, so that the first eccentric wheel 312 can be driven to slide when the slider 521 slides.

[0053] The outer side of the slider 521 is formed with an outer screw hole 5213, and the inner screw hole 5213 is provided with an inner thread, and the outer screw hole 5213 is threadedly matched with the screw rod 522. When the screw rod 522 rotates, since the inner sleeve hole 5211 of the slider 521 is limited to the first eccentric wheel 312, the rotation of the screw rod 522 is converted into the axial sliding of the slider 521.

[0054] The slider 521 includes an upper slider 521a and a lower slider 521b. The upper slider 521a and the lower slider 521b are buckled up and down to buckle and fix the first eccentric wheel 312 and the screw rod 522 to facilitate assembly operation.

[0055] In this embodiment, the first eccentric wheel 312 and the second eccentric wheel 322 both include an inner eccentric wheel 33 and an outer eccentric wheel 34, and the surfaces of the inner eccentric wheel 33 and the outer eccentric wheel 34 facing each other are arranged as inclined surfaces, and a connecting portion 331 extends from the inclined surface of the inner eccentric wheel 33 toward the inclined surface of the outer eccentric wheel 34; the massage main shaft 2 eccentrically passes through the first eccentric wheel 312 and the second eccentric wheel 322, and the axial direction of the connecting portion 331 is inclined to the axial direction of the massage main shaft 2;

[0056] The first massage arm 311 and the second massage arm 321 are provided with a connecting sleeve hole 35 and a massage panel 36 at both ends, respectively. The connecting sleeve hole 35 can be relatively rotatably sleeved on the connecting portion 331 , and the massage panel 36 is provided with a massage protrusion structure.

[0057] At the same time, the first massage arm 311 and the second massage arm 321 are also provided with a limiting column 37, and the limiting column 37 is used to cooperate with the limiting slot 38 to limit the rotation of the first massage arm 311 and the second massage arm 321. For details, see Figure 7 A first limiting column 371 may be provided below the first massage arm 311. The first limiting column 371 moves up and down and is limited in the front and rear directions and is inserted into the first limiting slot 381 below the massage main shaft 2. Figure 5 A second limiting column 372 may be provided on the side of the second massage arm 321 . The second limiting column 372 is movable left and right and is limited in the up and down directions and is inserted into the second limiting slot 382 on the side of the massage main shaft 2 .

[0058] Therefore, when the first eccentric wheel 312 and the second eccentric wheel 322 rotate, the connecting portion 331 performs eccentric motion around the massage main shaft 2, and drives the massage panels 36 of the first massage arm 311 and the second massage arm 321 to swing, thereby achieving a massage effect.
