Description

Technical Field

[0001] The utility model relates to the technical field of fascia guns, in particular to a fascia gun with a novel heating connection structure. Background Art

[0002] The fascia gun is a soft tissue rehabilitation tool that relaxes the body's soft tissue through high-frequency impact. To facilitate people's use, existing fascia guns are also equipped with a heating function, and a heating element is usually installed in the massage head.

[0003] There are usually two types of existing fascia guns with heating functions. One type of fascia gun has a heating element in the massage head directly connected to the circuit board in the fascia gun housing through a long wire. The other type, such as the Chinese utility model patent disclosed on July 18, 2023, with the announcement number CN219354617U, is a fascia gun with a hot compress function. The second battery module and the second PCB circuit board independently arranged directly in the massage head are used to supply power to the heating element, which has both vibration massage function and hot compress function.

[0004] Both types of fascia guns have certain problems when used. The first type of fascia gun: Since the heating element in its massage head is directly connected to the circuit board in the fascia gun shell through a long wire, the massage head cannot be replaced at will (the existing massage heads include spherical heads, conical heads, U-shaped heads and flat heads), and cannot meet people's different needs (the spherical head is mainly used for massaging large muscle groups, such as the chest, back and legs, the conical head is more suitable for small muscle groups, such as the palms and soles of the feet, the flat head is mainly used for local muscle relaxation and shaping, and the U-shaped head is suitable for strip muscle groups, such as shoulders, neck, tendons and spine massage). The second type of fascia gun: Due to the limited space inside the massage head, the installed battery module is small, the power supply and hot compress time is short, and the battery module and circuit board are prone to unstable fixation and poor contact with the wires under the violent shaking of the massage head. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a fascia gun with a novel heating connection structure to solve the problems that the massage head of the existing fascia gun cannot be replaced at will, and when the battery module and the circuit board are installed in the massage head, the installed battery module is small, the power supply and hot compress time is short, and the battery module and the circuit board are prone to unstable fixation and poor contact with the wires under the violent shaking of the massage head.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a fascia gun with a novel heating connection structure, comprising a shell and a massage head, wherein a power supply, a reciprocating drive mechanism and a circuit board are arranged inside the shell, wherein the power supply and the circuit board are connected through a wire, wherein the reciprocating drive mechanism drives the massage head to reciprocate, wherein a heating element is arranged inside the massage head, and further comprising:

[0007] A movable sleeve is fixedly arranged at the output end of the reciprocating drive mechanism, and the massage head is detachably fixed in the movable sleeve;

[0008] A conductive plate is fixedly disposed in the movable sleeve, and the conductive plate is electrically connected to the circuit board through a wire;

[0009] A conductive probe is fixedly arranged at one end of the massage head facing the conductive plate.

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments. However, the following embodiments are only preferred embodiments of the present invention, not all of them. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work all belong to the protection scope of the present invention. The experimental methods in the following embodiments are conventional methods unless otherwise specified. The materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.

[0026] like Figure 1-Figure 4 As shown, the utility model provides a fascia gun with a novel heating connection structure, including a shell 1 and a massage head 4, wherein a power supply 2, a reciprocating drive mechanism 3 and a circuit board 13 are arranged inside the shell 1 (the specific structure and working principle of the reciprocating drive mechanism 3 are prior art and are not described in detail here), the power supply 2 is connected to the circuit board 13 through a wire, the reciprocating drive mechanism 3 drives the massage head 4 to reciprocate, a heating element 8 is arranged inside the massage head 4 (this is an existing structure and is not described in detail here), and further comprises a movable sleeve 5, a conductive plate 6 and a conductive probe 7;

[0027] The movable sleeve 5 is fixedly arranged at the output end of the reciprocating drive mechanism 3, and the massage head 4 is detachably fixed in the movable sleeve 5. The reciprocating drive mechanism 3 drives the movable sleeve 5 to reciprocate, thereby driving the massage head 4 to reciprocate;

[0028] The conductive plate 6 is fixedly disposed in the movable sleeve 5, and the conductive plate 6 is electrically connected to the circuit board 13 through a wire;

[0029] The conductive probe 7 is fixedly arranged at one end of the massage head 4 facing the conductive plate 6. One end of the conductive probe 7 is electrically connected to the heating element 8 through a wire. When the massage head 4 is fixed in the movable sleeve 5, the other end of the conductive probe 7 is in contact with the conductive plate 6 and is electrically connected.

[0030] When in use, the conductive plate 6 is fixed in the movable sleeve 5, and then the massage head 4 is fixed in the movable sleeve 5. At this time, one end of the conductive probe 7 is in contact with and electrically connected to the conductive plate 6, and the other end of the conductive probe 7 is electrically connected to the heating element 8 through a wire. Since the conductive plate 6 is electrically connected to the circuit board 13 through a wire, the power supply 2 in the housing 1 can supply power to the reciprocating drive mechanism 3 while also supplying power to the heating element 8. Compared with the existing battery module and circuit board 13 independently arranged in the massage head 4, when the battery module and the circuit board 13 are installed in the massage head 4, the battery module installed is smaller, the power supply and hot compress time is short, and the battery module and the circuit board 13 are prone to unstable fixation and poor contact with the wire when the massage head 4 is violently shaken.

[0031] At the same time, when the massage head 4 needs to be replaced, the massage head 4 can be directly disassembled to separate it from the movable sleeve 5. At this time, the conductive probe 7 is separated from the conductive plate 6 and no longer in contact, and the heating element 8 and the circuit board 13 are not directly connected by a wire, thereby facilitating the disassembly and replacement of the massage head 4 to meet people's different needs.

[0032] like Figure 2 and Figure 4 As shown, the conductive plate 6 is detachably fixed in the movable sleeve 5, the support plate 51 is fixedly installed in the movable sleeve 5, and the bottom surface of the conductive plate 6 is fixedly installed with a bottom plate 11. The size of the bottom plate 11 is not larger than the opening size of the movable sleeve 5, so that the bottom plate 11 can be moved in and out of the movable sleeve 5. The bottom plate 11 is fixed with the support plate 51 by screws when they are fitted together;

[0033] When the conductive plate 6 needs to be fixedly installed, the base plate 11 is placed into the movable sleeve 5 opposite the support plate 51 until the base plate 11 and the support plate 51 are fitted together. At this time, screws are used to penetrate the support plate 51 and enter the base plate 11, thereby completing the fixation of the support plate 51, i.e., the conductive plate 6, so that when the massage head 4 is installed later, the conductive probe 7 at one end of the massage head 4 contacts the conductive plate 6 and is energized.

[0034] like Figure 4 As shown, specifically, the bottom plate 11 is detachably fixedly connected to the conductive plate 6, and the bottom plate 11 is detachably connected to the first fixed cover 9, the first fixed cover 9 is columnar, and the first fixed cover 9 has openings at both ends and is hollow inside, and the first fixed cover 9 is provided with a first inner edge at one end away from the bottom plate 11. When the first fixed cover 9 is located on the bottom plate 11, the first inner edge presses and fixes the conductive plate 6 on the bottom plate 11;

[0035] By providing the first fixing cover 9, after the conductive plate 6 is placed on the bottom plate 11, the first fixing cover 9 can be fixed on the bottom plate 11, and the conductive plate 6 can be pressed and fixed on the bottom plate 11 by the first inner edge of the first fixing cover 9, thereby completing the fixation of the conductive plate 6. When the conductive plate 6 is damaged during use, it is only necessary to remove the first fixing cover 9 and directly remove the conductive plate 6 from the bottom plate 11 to complete the separate replacement of the conductive plate 6, without replacing the conductive plate 6 and the bottom plate 11 as a whole, thereby saving materials.

[0036] like Figure 2 and Figure 3As shown, the end of the massage head 4 facing the conductive plate 6 is detachably fixedly connected with a second fixed cover 10, the size of the second fixed cover 10 is not larger than the size of the tube mouth of the movable sleeve 5, to ensure that when the massage head 4 is installed in the movable sleeve 5, the second fixed cover 10 can normally enter the movable sleeve 5, the second fixed cover 10 is columnar, with openings at both ends and a hollow interior, the second fixed cover 10 is provided with a second inner edge at the end away from the massage head 4, a groove is provided at the end of the massage head 4 facing the conductive plate 6, a support block 71 is placed in the groove, a plurality of conductive probes 7 are fixed on the support block 71, and when the second fixed cover 10 is fixed on the massage head 4, the second inner edge presses the support block 71 tightly and fixes it in the groove;

[0037] The conductive probe 7 is positioned and fixed by the support block 71. When the conductive probe 7 needs to be installed, the support block 71 is placed in the groove, and then the second fixing cover 10 is fixed to the end of the massage head 4 facing the conductive plate 6, so that the second inner edge of the second fixing cover 10 presses the support block 71 tightly and fixes it in the groove, thereby completing the fixing of the support block 71, i.e., the conductive probe 7;

[0038] On the contrary, when the conductive probe 7 is damaged, after the massage head 4 is disassembled from the movable sleeve 5, the second fixed cover 10 is removed from one end of the massage head 4, and the second inner edge no longer presses and fixes the support block 71, so that the support block 71 and the conductive probe 7 can be taken out of the groove, and the conductive probe 7 can be quickly disassembled, assembled and replaced.

[0039] like Figure 3 As shown, a protective block 72 is provided on the support block 71, and a plurality of through holes 721 adapted to the conductive probe 7 are opened on the protective block 72, and the protective block 72 is located between the support block 71 and the second inner edge. When the second fixing cover 10 is fixed on the massage head 4, the second inner edge presses and fixes the protective block 72 on the support block 71;

[0040] By adding the protection block 72, the outer periphery of the conductive probe 7 protruding from the top surface of the support block 71 can be protected to prevent the conductive probe 7 from protruding too long from the support block 71 and contacting the conductive plate 6, thereby preventing the conductive probe 7 from bending and tilting, resulting in failure to conduct electricity.

[0041] Since the conductive probe 7 is in contact with and electrically connected to the conductive plate 6 , the conductive probe 7 penetrates the protection block 72 and the second fixing cover 10 .

[0042] like Figure 4 As shown, the first fixed cover 9 is screwed or screwed to the bottom plate 11;

[0043] Here, the screw fixation of the first fixing cover 9 and the bottom plate 11 is taken as an example. Specifically, an internal thread is set on the inner wall of the first fixing cover 9, and an external thread matched with the internal thread is set on the outer wall of the bottom plate 11. The two are fixed by screw connection, so as to facilitate the disassembly and assembly of the first fixing cover 9 and the bottom plate 11. When the conductive plate 6 is damaged, after the first fixing cover 9 and the bottom plate 11 are taken out as a whole, only the conductive plate 6 needs to be replaced separately, and there is no need to replace the bottom plate 11.

[0044] like Figure 3 As shown, the second fixing cover 10 is screwed or screwed to the massage head 4;

[0045] Here, the second fixing cover 10 and the massage head 4 are fixed by a screw-lock as an example. For details, reference may be made to the existing lampshade screw-lock structure (such as a screw-lock structure with announcement number CN210153732U and a screw-lock structure in a lamp), which will not be described in detail here.

[0046] like Figure 2-Figure 4 As shown, a fixing ring 12 is fixedly installed on the periphery of the massage head 4, the fixing ring 12 is made of rubber, and the massage head 4 and the movable sleeve 5 are connected by interference fit through the fixing ring 12;

[0047] The massage head 4 can be inserted and fixed in the movable sleeve 5 by the fixing ring 12, which is stable and convenient for disassembly and replacement of the massage head 4.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
