Technical Field

[0001] The utility model relates to the technical field of fascia guns, in particular to a compact and small-sized fascia gun. Background Technique

[0002] A fascia gun is a soft tissue rehabilitation tool, that is, it relaxes the soft tissues of the body through high-frequency impacts.

[0003] For the fascia gun key assembly of the Chinese utility model patent publicly disclosed on December 19, 2023, with the announcement number CN220208781U, a bolt passes through the circuit board and is inserted into a threaded cylinder and threadedly connected thereto, so that the circuit board can be kept in the current position and will not have a gap due to the extrusion of the pressing force.

[0004] However, the circuit board of this fascia gun is fixed by inserting a bolt through the circuit board and into the threaded cylinder and threadedly connecting them, which requires drilling the circuit board.

[0005] There are the following problems with drilling the circuit board: (1) Drilling holes in the circuit board will reduce the available area for placing components on the circuit board. Therefore, it is usually solved by increasing the area of the circuit board or increasing the number of circuit boards, both of which will increase the volume of the fascia gun; (2) Drilling holes in the circuit board will increase the production process, which will not only increase the production cost but also reduce the production efficiency. Content of the Utility Model

[0006] In order to overcome the deficiencies of the prior art, the utility model provides a compact and small-sized fascia gun to solve the problems that the existing circuit board needs to be fixed by drilling holes in the circuit board, which will increase the volume of the fascia gun, increase the production cost, and reduce the production efficiency.

[0007] To solve the above technical problems, the utility model provides the following technical solution: A compact and small-sized fascia gun includes a housing and a massage head. A power supply, a reciprocating drive mechanism, and several circuit boards are arranged inside the housing. The reciprocating drive mechanism drives the massage head to reciprocate. Several support structures for supporting the circuit boards and limiters for limiting and fixing the circuit boards on the support structures are arranged inside the housing.

[0008] Preferably, the housing includes a first outer shell and a second outer shell that are detachably connected. The limiter is a screw.

When the nut is screwed and fixed on the lower support member, the nut or the screw rod abuts against one side of the circuit board.

[0010] Preferably, a plurality of side grooves adapted to the thickness of a single circuit board are symmetrically formed on both sides of the inner wall of the first housing. The circuit board is slidably disposed in the side grooves. The support structure is the top surface and the bottom surface of the inner wall of the side grooves. When the screw is screwed and fixed on the first housing, the nut abuts against one side of the circuit board.

[0011] Preferably, at least one of the opposite surfaces of the lower support member and the upper support member in contact with the circuit board is provided with an arc-shaped convex surface.

[0019] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the following combines specific embodiments to further elaborate on the present utility model. However, the following embodiments are only the preferred embodiments of the present utility model, not all of them. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative labor all belong to the protection scope of the present utility model. The experimental methods in the following embodiments are all conventional methods unless otherwise specified. The materials, reagents, etc. used in the following embodiments can all be obtained from commercial channels unless otherwise specified.

[0020] As Figures 1 - 3 shown, the present utility model provides a compact and small-sized fascia gun, which includes a housing 1 and a massage head 4. Inside the housing 1, there are a power source 2, a reciprocating drive mechanism 3 (not fully shown here, which is prior art and the specific structural principle will not be elaborated here), and several circuit boards 5. The reciprocating drive mechanism 3 drives the massage head 4 to reciprocate. In the housing 1, there are several support structures for supporting the circuit boards 5 and limit members 8 for limiting and fixing the circuit boards 5 to the support structures.

[0021] When installing the circuit board 5, by placing the circuit board 5 on the support structure and then using the limit member 8 to limit and fix the circuit board 5 to the support structure, the circuit board 5 is fixed in place. Compared with the existing method of using screws to penetrate the circuit board 5 for fixation, it can avoid damage to the circuit board 5 and make the most of the area for placing components on the circuit board 5. Thus, it is possible to avoid using a large-area circuit board 5 or increasing the number of circuit boards 5 after opening holes on the circuit board 5. This not only saves production costs but also achieves the purpose of reducing the overall volume of the fascia gun, making its structure more compact and small.

[0022] At the same time, reducing the process of opening holes on the circuit board 5 reduces production costs to a certain extent and improves production efficiency.

[0023] As Figure 1 and Figure 3 shown, the housing 1 includes a detachable first outer shell 11 and a second outer shell 12. The limit member 8 is a screw. When the circuit board 5 is located on the support structure and the screw is screwed and fixed inside the housing 1, both sides of the circuit board 5 are respectively in contact with the inner wall of the first outer shell 11 and the screw.

[0024] The support structure completes the vertical limit and fixation of the circuit board 5, and the screw cooperates with the outside of the first outer shell 11 to complete the horizontal limit and fixation of the circuit board 5, thereby completing the fixation of the circuit board 5.

[0025] Specifically, the support structure can be the following two types:

[0026] Embodiment 1:

[0027] AsFigure 3 As shown, the support structure includes a lower support member 6 and an upper support member 7 provided on both sides of the inner wall of the first housing 11. The lower support member 6 and the upper support member 7 are respectively in contact with the bottom surface and the top surface of the circuit board 5. The screw includes a screw rod and a nut. When the nut is screwed and fixed on the lower support member 6, the nut or the screw rod abuts against one side of the circuit board 5;

[0028] Taking the example that the nut abuts against one side of the circuit board 5, threaded holes adapted to the screws can be preset on the lower support member 6:

[0029] When the circuit board 5 needs to be installed, the circuit board 5 is inserted between the lower support member 6 and the upper support member 7, so that the lower support member 6 and the upper support member 7 limit and fix the circuit board 5 in the vertical direction (perpendicular to the top surface of the circuit board 5). Then, the screw is inserted and screwed and fixed on the lower support member 6 along the direction parallel to the top surface of the circuit board 5 until the nut abuts against one side of the circuit board 5, and three sides of the four sides of the outer wall of the circuit board 5 abut against the inner wall of the first housing 11, thereby completing the limit and fixation of the circuit board 5 in the horizontal direction (parallel to the top surface of the circuit board 5);

[0030] Compared with the existing method of using screws to penetrate the circuit board 5 for fixation, it can avoid damage to the circuit board 5 and can make the most of the area for placing components on the circuit board 5, thereby avoiding selecting a large-area circuit board 5 or increasing the number of circuit boards 5 after opening holes in the circuit board 5, achieving the purpose of reducing the overall volume of the fascia gun and making its structure more compact and small;

[0031] In addition, the screw can also be inserted and fixed on the lower support member 6 along the direction perpendicular to the top surface of the circuit board 5 (not shown in the figure). At this time, the screw rod or the nut limits and abuts against the circuit board 5 for fixation.

[0032] Embodiment 2:

[0033] A plurality of side grooves adapted to the thickness of a single circuit board 5 are symmetrically opened on both sides of the inner wall of the first housing 11. The circuit board 5 is slidably arranged in the side grooves. The support structure is the top surface and the bottom surface of the inner wall of the side grooves. When the screw is screwed and fixed on the first housing 11, the nut abuts against one side of the circuit board 5;

[0034] By opening side grooves on the first housing 11, after the circuit board 5 is slidably arranged in the side grooves, the top surface and the bottom surface of the inner wall of the side grooves limit and fix the circuit board 5 in the vertical direction (perpendicular to the top surface of the circuit board 5). Then, the screw is inserted and screwed and fixed on the first housing 11 along the direction parallel to the top surface of the circuit board 5 until the nut abuts against one side of the circuit board 5, and three sides of the four sides of the outer wall of the circuit board 5 abut against the inner wall of the first housing 11 or one side of the inner wall of the side grooves, thereby completing the limit and fixation of the circuit board 5 in the horizontal direction (parallel to the top surface of the circuit board 5).

[0035] By providing side grooves on both sides of the inner wall of the first housing 11, compared with the first embodiment, the trouble of arranging the lower support member 6 and the upper support member 7 can be avoided, and materials can be saved. However, the thickness of the shell of the first housing 11 is generally small, so side grooves need to be opened on the first housing 11, and the processing difficulty is also relatively large. At the same time, when the screw is screwed and fixed on the first housing 11, it is easy to damage the first housing 11. The specific setting method of the support structure can be selected according to needs;

[0036] It should be noted that when the screw is fixed on the first housing 11, the nut will protrude from the first housing 11. Therefore, an avoidance hole can be opened at the position of the second housing 12 facing the nut to ensure the normal buckling of the first housing 11 and the second housing 12.

[0037] Such as Figure 3 shown, at least one of the opposite surfaces of the lower support member 6 and the upper support member 7 and the circuit board 5 is provided with an arc-shaped convex surface;

[0038] Taking the lower support member 6 as a cylindrical threaded cylinder as an example here, when the circuit board 5 is slidably placed between the lower support member 6 and the upper support member 7, the contact area between the circuit board 5 and the lower support member 6 can be reduced. Thus, when the circuit board 5 slides between the lower support member 6 and the upper support member 7, the contact between the lower support member 6 and the circuit board 5 and the components on the circuit board 5 can be minimized as much as possible, thereby reducing the wear of the lower support member 6 on the circuit board 5 and the components on the circuit board 5.

[0039] At least one of the top surface and the bottom surface of the inner wall of the side groove is provided with an arc-shaped convex surface;

[0040] Similarly to the above, when the circuit board 5 slides in the side groove, the contact area between the circuit board 5 and the top surface and the bottom surface of the inner wall of the side groove can be reduced. Thus, when the circuit board 5 slides on the top surface and the bottom surface of the inner wall of the side groove, the contact between the top surface and the bottom surface of the inner wall of the side groove and the circuit board 5 and the components on the circuit board 5 can be minimized as much as possible, thereby reducing the wear of the top surface and the bottom surface of the inner wall of the side groove on the circuit board 5 and the components on the circuit board 5.

[0041] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
