Description

Technical Field

[0001] This utility model belongs to the field of aromatherapy technology, specifically relating to a massager. Background Technology

[0002] As living standards continue to improve, people are paying more and more attention to their physical and mental health, leading to a growing demand for various nutritional supplements and massage devices. Massage devices use motors to generate movements such as vibration, rotation, and linear reciprocating motions, thereby applying massage actions such as pressing and kneading to the human body.

[0003] However, most existing handheld massagers have the following drawbacks: 1) Handheld massagers are relatively short overall. When needing to massage the muscles of the back or calves, it is difficult to reach the massage head to the desired area or requires bending over to operate, resulting in poor applicability. To address this issue, the current solution is to add a thinner and longer handle to extend the overall length of the massager. The handle and massage head are usually fixed by a snap-fit ​​or simple threaded connection. However, because the handle is long and thin, this connection method makes it easy for the connection between the massage head and the handle to break when the massager is under stress. Secondly, the length of the handle is fixed and cannot be adjusted, which also limits its usage scenarios. Utility Model Content

[0004] The purpose of this utility model is to overcome the existing technical defects and provide a massager that improves the connection structure between the handle and the massage head, thereby increasing the strength of the connection and preventing breakage during use.

[0036] To better understand the technical content of this utility model, the following will further introduce and explain this utility model in conjunction with the accompanying drawings and specific embodiments. It should be noted that if there are descriptions such as "first" and "second" in the text, they are used to distinguish different components, etc., and do not represent the order of priority, nor do they limit "first" and "second" to be different types.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0038] Example 1

[0039] like Figures 1 to 8 As shown in the figure, the massager in this embodiment includes a handle 1 and a massage head 2. One end of the handle 1 is provided with a first insertion groove 10, and one end of the massage head 2 is provided with a first insertion rod 21 that is inserted into the first insertion groove 10. The end of the handle 1 near the massage head 2 is provided with a first threaded part 11. The outside of the first insertion rod 21 is rotatably fitted with a first threaded cover 22 that is threadedly connected to the first threaded part 11. In this structure, an insertion groove is first added to the handle and an insertion rod is added to the massage head. The insertion rod is used to increase the connection area and area between the handle and the massage head. The insertion structure of the insertion rod improves the force and strength at the connection point between the two, avoiding the problem of breakage during use. The threaded cover and the threaded part are used to achieve threaded connection and fixation. The connection process and structure are simple and reliable.

[0040] In practice, such as Figures 2 to 8As shown, to better realize the operation and control of the massager, the control part of the massager is usually located inside the handle. That is, the handle 1 contains a control board 12, a charging board 13 electrically connected to the control board 12, and a battery 14. The charging board 13 has a charging interface 131 exposed on one side or at the end of the handle 1. After the charging board 13 is connected to an external power source, it charges the internal battery 14 or directly powers the whole machine. The control board 12 has multiple control switches 121, and one side of the handle 1 has multiple buttons 15 for pressing the control switches 121 one by one. The massage head 2 has a vibration motor 23 inside at the end away from the handle 1. The rotating shaft of the vibration motor 23 has an eccentric rotor 231, so that the massage head vibrates through the vibration motor, and massages... Two exposed electrode pads 24 are provided at the end of the head 2 furthest from the handle 1. When the electrode pads 24 are energized and come into contact with the skin, they can generate current stimulation. The operation of the vibration motor 23 and the electrode pads 24 is controlled by the control board 12. Both can be turned on at the same time to achieve the dual effect of vibration and electrical stimulation on the human body, that is, to perform vibration massage and microcurrent electric shock on the human body, stimulate acupoints on the skin surface, and play a health care role in relieving fatigue and relaxing muscles. Alternatively, depending on the actual needs, only the vibration motor 23 or the electrode pads 24 can be turned on to achieve a single vibration massage effect or current stimulation effect. It is understood that the control switch 121 is preferably three: one is the power switch of the whole machine, one is the control switch of the vibration motor 23, and one is the control switch of the electrode pads 24.

[0041] As a preferred option, such as Figures 3 to 4 As shown, in order to realize the detachable structure and electrical connection between the handle and the massage head, a first circuit board 16 electrically connected to the control board 12 is provided in the first insertion slot 10. The first circuit board 16 is provided with four conductive spring pins 161. A second circuit board 25 is provided at the end of the first plug rod 21. The outer side of the second circuit board 25 is provided with four conductive contacts 251 that abut against the conductive spring pins 161 one by one. The vibration motor 23 and the electrode plate 24 are electrically connected to the second circuit board 25 through wires (not shown in the figure), thereby realizing the electrical connection between the handle and the massage head by utilizing the abutting relationship between the first circuit board and the second circuit board.

[0042] In one embodiment, such as Figure 2 As shown, the control panel 12 also has a display screen 17 exposed on one side of the handle.

[0043] In one embodiment, such as Figures 2 to 6As shown, the inner wall of the first insertion groove 10 has two protruding guide ribs 101 arranged along its groove depth, and the two guide ribs 101 are symmetrically arranged. The outer periphery of the first insertion rod 21 has two guide grooves 211 for the guide ribs 101 to be inserted one by one. The inner wall of the first insertion groove 10 has two limiting planes 102 arranged along its groove depth, and the two limiting planes 102 are symmetrically arranged. The line connecting the two limiting planes 102 is perpendicular to the line connecting the two guide ribs 101. The outer periphery of the first insertion rod 21 has two guide planes 212 that cooperate with the limiting planes 102. Through the above structure, the insertion process of the first insertion rod 21 is guided and limited, avoiding the problem of self-deflection of the first insertion rod 21. After insertion, the conductive spring pin 161 and the conductive contact 251 can be connected one by one.

[0044] In one embodiment, such as Figures 4 to 8 As shown, the outer periphery of the first insertion rod 21 away from the handle 1 has two symmetrically arranged limiting blocks 213 protruding, and an annular limiting groove 214 is formed between the end of the first insertion rod 21 away from the handle 2 and the limiting block 213. The end of the first threaded cover 22 near the massage head 2 has a through hole 221 for the first insertion rod 21 to pass through. The wall surface of the through hole 221 has two clearance notches 222 for the limiting blocks 213 to pass through one by one, so that one end of the first threaded cover 22 passes through the limiting block 213 and enters the limiting groove 214, so that the first threaded cover 22 is rotatably disposed in the limiting groove 214.

[0045] In one embodiment, such as Figures 7 to 8 As shown, the massage head 2 includes a rod portion 201 and a massage portion 202 disposed at one end of the rod portion 201. A first insertion rod 21 is disposed at the end of the rod portion 201 away from the massage portion 202. A vibration motor 23 and an electrode plate 24 are disposed on the massage portion 202.

[0046] Optional, such as Figures 7 to 8 As shown, in order to install the vibration motor, a cover 203 fixed by screws is provided on one side of the massage part 202 to form a detachable structure. A cavity for accommodating the vibration motor 23 is formed between the cover 203 and the massage part 202, so that the vibration motor 23 can be installed inside the massage part 202 after the cover 203 is removed.

[0047] Optional, such as Figures 5 to 8 As shown, in order to improve the comfort during use, silicone sleeves 204 that are adapted to the shape are fitted around the outer periphery of the rod 201 and the massage part 202. The electrode plate 24 is exposed outside the silicone sleeve 204. The rod 201, the massage part 202 and the cover are usually made of plastic, and the rod 201 and the massage part 202 are integrally molded.

[0048] In one specific embodiment, such as Figure 7 As shown, a wiring groove 205 is recessed on one side of the rod 201 and the massage part 202. One end of the wiring groove 205 is connected to the cavity inside the massage part to accommodate the wires between the vibration motor and the electrode plate and the second circuit board. The wiring groove is wrapped inside by a silicone sleeve. The middle of the first plug rod 21 is a hollow structure. One end of the rod 201 is provided with a right-angle hole or T-shaped hole 206 that connects the wiring groove 205 and the inside of the first plug rod 21.

[0049] In one embodiment, such as Figures 4 to 8 As shown, the massage head 202 and the cover are assembled into an ellipsoidal shape, forming a certain angle with the shaft 201, so that the massage head is shaped like a golf club. This shape can be better adapted to the joints and curved parts of the human body for use.

[0050] Example 2

[0051] like Figures 9 to 10 As shown in the figure, the overall structure of the massager shown in this embodiment is basically the same as that shown in embodiment 1. The difference is that the shape of the massage part in the massage head is different. In this embodiment, the massage part and the cover are combined to form a spherical structure. This shape can be better adapted to the palms, soles and other parts of the body for use.

[0052] Example 3

[0053] like Figures 11 to 12 As shown, the massager in this embodiment has a similar overall structure to that in embodiment 1. The difference is that the shape of the massage part in the massage head is different. In this embodiment, the massage part and the cover are combined to form a heart-shaped structure. This shape allows for better use on various muscle parts of the human body, especially the back. The silicone sleeve 204 on the outside of the rod 201 and the massage part 202 is made in one piece.

[0054] In this embodiment, the massage part 202 has an arched soft rubber 207 on the side away from the cover 203, and the soft rubber 207 is located inside the silicone sleeve 204. Utilizing the soft properties of the soft rubber 207 inside, the massage head can be used to tap acupoints on the body. Therefore, after the vibration function is activated, by tapping acupoints or tired areas, vibration and tapping can eliminate the soreness of the thigh muscles, thereby achieving the health benefits of relaxing muscles and reducing fatigue.

[0055] Example 4

[0056] like Figures 13 to 15As shown, the massager in this embodiment has a generally similar structure to that shown in any one of embodiments 1-4, except that: the massager also includes a hollow extension rod 3, with a second insertion rod 31 inserted into the first insertion slot 10 at one end of the extension rod 3, and a second threaded cover 32 that is threadedly connected to the first threaded portion 11 is rotatably sleeved on the outside of the second insertion rod 31; the other end of the extension rod 3 is provided with a second insertion slot 33 for the first insertion rod 21 to be inserted into, and the end of the extension rod 3 away from the handle 1 is provided with a second threaded portion 34 that is threadedly connected to the first threaded cover 22; the second insertion rod 31 has the same shape as the first insertion rod 31, and the second insertion slot 33 has the same shape as the first insertion slot 10. The second threaded cap 32 has the same shape as the first threaded cap 22; a third circuit board 35 is provided inside the outer end of the second plug rod 31, and four conductive contacts 251 are provided on the outer side of the third circuit board 35; a fourth circuit board 36 electrically connected to the third circuit board 35 is provided inside the second insertion slot 33, and four conductive spring pins 161 are provided on the outer side of the fourth circuit board 36. Thus, the length of the entire massager can be increased by using this extension rod, and the connection between the third circuit board and the fourth circuit board will not affect the electrical connection between the handle 1 and the massage head 2. Therefore, the extension rod can be selected according to actual needs to adapt to different massage positions and different massage needs, thereby improving the scope of use and applicable scenarios of the massager.

[0057] In one embodiment, the third circuit board 35 has the same shape as the second circuit board 25, and the fourth circuit board 36 has the same shape as the first circuit board 16.
