Description

Technical Field

[0001] This utility model relates to the field of fascia gun technology, and in particular to a fascia gun with a novel electrical structure. Background Technology

[0002] Fascia guns, also known as deep myofascial impactors, use a specially designed high-speed motor inside to drive the tapping head and generate high-frequency vibrations that penetrate deep into the muscles. This high-frequency vibration can achieve a massage effect, reducing local tissue tension, relieving muscle soreness, and promoting blood circulation.

[0003] A fascia gun with a handle extension function, published on October 4, 2022, has an extension handle fitted onto the main handle and fixed by a locking device. After disassembly, the main handle can be used independently. After assembly, the extension handle and the main handle work together to effectively expand the area and range of use for the user, avoiding the technical defects of inconvenience or inability to reach certain massage positions when massaging muscles in certain areas.

[0004] However, this fascia gun only uses a simple mechanical locking device to fix the main handle and the extension handle. The motor and other drive structures of the fascia gun, as well as the power supply, are all located in the fascia gun body and the main handle. When the extension handle is attached to the main handle, although it can effectively expand the area and range of use for the user, it will make the end of the fascia gun body and the main handle too heavy. At the same time, the fascia gun will generate a large impact force when it is working, which makes it more difficult for people to hold the extension handle. In severe cases, it may even injure the wrist. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model provides a fascia gun with a novel power-conducting structure. This addresses the issue that the motor and other drive structures, as well as the power supply, are all located at the fascia gun body and main handle. While attaching an extension handle to the main handle can effectively expand the user's usable area, it also results in one end of the fascia gun body and main handle becoming excessively heavy. Furthermore, the fascia gun generates significant impact force during operation, making it more difficult for users to grip the extension handle and potentially causing wrist injuries in severe cases.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a fascia gun with a novel electrically conductive structure, comprising a handle and a massage part, wherein a power source is provided in the handle, and a transmission mechanism is provided in the massage part. The electrically conductive structure includes a first conductive element and a second conductive element. The first conductive element is provided on the handle and is electrically connected to the power source via a wire. The second conductive element is provided on the massage part and is electrically connected to the transmission mechanism via a wire. The fascia gun further includes: The bending extension has a first conductive element and a second conductive element at its two ends, and the first conductive element and the second conductive element at its two ends are electrically connected by a wire. When the handle and massage parts are detachably and fixedly connected to form a fascia gun in a first use state, or when the two ends of the bent extension are detachably and fixedly connected to the handle and massage parts respectively to form a fascia gun in a second use state, each first conductive element is electrically connected to a second conductive element in contact.

[0007] Preferably, the first conductive element and the second conductive element are in plug-in contact.

[0008] Preferably, the first conductive element / second conductive element is a probe / ring conductive sheet or a probe / hollow needle connector, and both the ring conductive sheet and the hollow needle connector are provided with a socket adapted to the size of the probe.

[0009] Preferably, the first conductive element and the second conductive element are in contact with each other.

[0010] Preferably, the first conductive element / second conductive element is a probe / spring.

[0011] Preferably, the fascia gun further includes a detachable fixing mechanism, which includes a first disassembly and a second disassembly and fixing structure that are detachably fixed. When the handle and the massage part are fixed by the detachable fixing mechanism, the fascia gun has a first use state. When the handle and the massage part are fixed by the detachable fixing mechanism at both ends of the bending extension part, the fascia gun has a second use state. The bending extension part includes at least one extension structure, and each extension structure has a first disassembly and a second disassembly and fixing structure at both ends. The extension structure is made of a deformable material and includes a deformable support member.

[0012] Preferably, the extension structure further includes a protective sleeve, which is fitted around the deformable support member.

[0013] Preferably, it also includes a limiting structure to prevent the protective sleeve from sliding on the deformable support.

[0014] Preferably, the limiting structure includes a recess and a protrusion adapted to the recess, the first disassembly structure includes a first connecting part, the second disassembly structure includes a second connecting part, when the first connecting part and / or the second connecting part has at least one recess or protrusion on its periphery, the inner wall of the protective sleeve has at least one protrusion or recess, and when the protective sleeve is fitted around the deformable support, the protrusion is located inside the recess.

[0015] Preferably, the limiting structure includes a stepped surface and an inner edge. The first and second disassembly structures are each provided with at least one stepped surface. The protective sleeve is open at both ends and has several inner edges extending toward the center of the opening. When the protective sleeve is fitted around the deformable support, each inner edge abuts against a stepped surface.

[0016] Compared with the prior art, the beneficial effects that this utility model can achieve are: By setting a first conductive element and a second conductive element, the power supply is located inside the handle, and the transmission mechanism is located inside the massage part. This ensures that the power supply provides power to the transmission mechanism when the handle and massage part are detachably and fixedly connected to form a fascia gun in the first use state, or when the two ends of the bent extension are detachably and fixedly connected to the handle and massage part respectively to form a fascia gun in the second use state. At the same time, since the power supply is located in the handle, the power supply and the transmission mechanism are located at opposite ends of the bent extension, avoiding the weight of both the power supply and the transmission mechanism being concentrated at the massage part at one end of the bent extension. This reduces the weight at the massage part, making it less strenuous for people to hold the fascia gun and effectively preventing wrist injuries. Attached Figure Description

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model is further described below in conjunction with specific embodiments. However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of this utility model.

[0019] like Figures 1-6 As shown, this utility model provides a fascia gun with a novel electrically conductive structure, including a handle 1 and a massage part 2. The handle 1 contains a power source, and the massage part 2 contains a transmission mechanism. Specifically, the transmission mechanism includes a motor and a cam reciprocating motion structure. This is an existing structure for fascia gun movement; the specific working principle is not detailed here. The fascia gun can be a single-head or double-headed fascia gun; the figure shows a double-headed fascia gun as an example. The electrically conductive structure includes a first conductive element 6 and a second conductive element 7. The first conductive element 6 is located on the handle 1 and is electrically connected to the power source via a wire. The second conductive element 7 is located on the massage part 2 and is electrically connected to the transmission mechanism via a wire. The fascia gun also includes: The bending extension has a first conductive element 6 and a second conductive element 7 at both ends, and the first conductive element 6 and the second conductive element 7 at both ends of the bending extension are electrically connected by a wire. When the handle part 1 and the massage part 2 are detachably and fixedly connected to form a fascia gun in the first use state, or when the two ends of the bent extension part are detachably and fixedly connected to the handle part 1 and the massage part 2 to form a fascia gun in the second use state, each first conductive element 6 is electrically connected to a second conductive element 7 in contact. When the handle part 1 and the massage part 2 are detachably and fixedly connected to form a combination as shown in the figure Figure 1 The fascia gun shown in the first usage state makes it convenient for people to use the fascia gun to massage the arms, legs and other parts. At this time, the power supply in the handle 1 conducts electricity to the first conductive part 6 on the handle 1 through the wire. After the first conductive part 6 on the handle 1 conducts electricity with the second conductive part 7 on the massage part 2, the second conductive part 7 on the massage part 2 is electrically connected to the transmission mechanism through the wire, thereby ensuring that the power supply provides power to the transmission mechanism. When the two ends of the bent extension are respectively detachably and fixedly connected to the handle part 1 and the massage part 2 to form a combination as shown in the figure Figure 2 The second usage state of the fascia gun shown allows users to massage their backs. In this state, the power source in the handle 1 conducts electricity to the first conductive element 6 on the handle 1 via a wire. The first conductive element 6 on the handle 1 contacts and conducts electricity with the second conductive element 7 at one end of the bent extension. The second conductive element 7 at one end of the bent extension conducts electricity with the first conductive element 6 at the other end of the bent extension via a wire. The first conductive element 6 on the bent extension then conducts electricity with the second conductive element 7 on the massage part 2. The second conductive element 7 on the massage part 2 is then electrically connected to the transmission mechanism via a wire, ensuring that the power source supplies power to the transmission mechanism. Furthermore, by placing the power source in the handle 1, the power source and transmission mechanism are located at opposite ends of the bent extension, preventing the weight of both from being concentrated at the massage part 2 at one end of the bent extension. This reduces the weight at the massage part 2, making it less strenuous for users to hold the fascia gun and effectively preventing wrist injuries.

[0020] like Figure 4 and Figure 5 As shown, the first conductive element 6 and the second conductive element 7 are in a plug-in contact. Specifically, the first conductive element 6 and the second conductive element 7 are probes / ring conductive sheets or probes / hollow needle connectors (such as hollow conductive posts). Both the ring conductive sheet and the hollow needle connector are provided with sockets that are adapted to the size of the probe, resulting in a wider contact surface and a more stable connection. In this diagram, the first conductive element 6 is used as a probe, and the second conductive element 7 is a hollow conductive post / ring-shaped conductive sheet as an example. When the handle part 1 and the massage part 2 are detachably and fixedly connected to form a combination as shown in the diagram... Figure 1 The first usage state of the fascia gun or the bent extension is shown to be detachably and fixedly connected to the handle part 1 and the massage part 2 at both ends to form a combination as shown. Figure 2 When the fascia gun is in the second usage state shown, normal conductivity is achieved by inserting the probe into the hollow conductive post or the annular conductive sheet. Alternatively, the first conductive element 6 can be a hollow conductive post / annular conductive sheet, and the second conductive element 7 can be a probe, which will not be elaborated here.

[0021] like Figure 4 and Figure 6 As shown, the first conductive element 6 and the second conductive element 7 are in a close-fitting contact. Specifically, the first conductive element 6 and the second conductive element 7 are probes / springs; The spring here can be set as a double spring. In this figure, the first conductive element 6 is used as a probe and the second conductive element 7 is a double spring as an example. When the handle part 1 and the massage part 2 are detachably and fixedly connected to form a combination as shown in the figure, the spring can be used as a combination of a double spring. Figure 1 The first usage state of the fascia gun or the bent extension is shown to be detachably and fixedly connected to the handle part 1 and the massage part 2 at both ends to form a combination as shown. Figure 2 When the fascia gun is in the second usage state shown, normal conductivity can also be achieved through the contact between the probe sidewall and the double spring sheet. Alternatively, the first conductive element 6 can be set as the double spring sheet and the second conductive element 7 as the probe, which will not be elaborated here.

[0022] like Figures 3-7 As shown, the fascia gun also includes a detachable fixing mechanism, which includes a first disassembly and assembly structure 4 and a second disassembly and assembly structure 5 that are detachably fixed. When the handle part 1 and the massage part 2 are fixed by the detachable fixing mechanism, the fascia gun has a first use state. When the two ends of the bending extension part are fixed by the detachable fixing mechanism, the fascia gun has a second use state. The bending extension part includes at least one extension structure 3. Each extension structure 3 has a first disassembly and assembly structure 4 and a second disassembly and assembly structure 5 at both ends. When there are two or more extension structures 3, two adjacent extension structures 3 are detachably fixedly connected by the first disassembly and assembly structure 4 and the second disassembly and assembly structure 5. When the handle part 1 is provided with a first disassembly structure 4 or a second disassembly structure 5, the massage part 2 is provided with a second disassembly structure 5 or a first disassembly structure 4. Through the detachable fixing mechanism composed of the first disassembly structure 4 and the second disassembly structure 5, the handle part 1 and the massage part 2 can be fixedly assembled into a fascia gun with a relatively short first use state, or the handle part 1, the bending extension part and the massage part 2 can be fixedly assembled into a fascia gun with a relatively long second use state. Thus, the overall length and use form of the fascia gun can be freely assembled and adjusted by people, which makes it convenient for users to choose to use it according to their own needs in different scenarios, and the application range is wider. Specifically, this example illustrates how a first disassembly / reassembly structure 4 is provided at one end of the massage part 2, and a second disassembly / reassembly structure 5 is provided at one end of the handle part 1. The first disassembly / reassembly structure 4 and the second disassembly / reassembly structure 5 are connected and rotated relative to each other to lock them in place. like Figure 4 , Figure 5 and Figure 6As shown, the second disassembly structure 5 includes a second cylinder 51, and the first disassembly structure 4 includes a first cylinder 41. One end of the first cylinder 41 has an opening that matches the size of the second cylinder 51. At least one positioning block 42 is fixed to the inner wall of the opening. The side of the positioning block 42 that is opposite to the inner wall of the opening has a positioning groove 43 along the central axis of the first cylinder 41. The outer edge of the second cylinder 51 has a second sliding groove 53 and a first sliding groove 52 that is not smaller than the size of the positioning block 42 along its central axis. The second sliding groove 53 is connected to the first sliding groove 52 in an L-shape. The inner wall of the second sliding groove 53 is provided with a limiting member 54. After the second cylinder 51 enters the first cylinder 41, it rotates relative to the first cylinder 41. When the positioning block 42 moves from the first sliding groove 52 to the second sliding groove 53, the limiting member 54 moves into the positioning groove 43, and the positioning block 42 is in contact with the inner wall of the second sliding groove 53. The limiting component 54 is a spring-loaded positioning ball or / and a rubber strip; This explanation uses a rubber strip as an example to illustrate the concept of limiting component 54: When it is necessary to fix the first disassembly structure 4 and the second disassembly structure 5, align one end of the second cylinder 51 with the opening of the first cylinder 41, and insert the positioning block 42 into the first slide groove 52 until the positioning block 42 is directly opposite the second slide groove 53. Then rotate the first cylinder 41 or the second cylinder 51 in the forward direction so that the positioning block 42 can enter the second slide groove 53. When the limiting member 54 is a rubber strip, when the first cylinder 41 or the second cylinder 51 is rotated in the forward direction, due to the interference fit of the rubber strip, when the rubber strip moves into the positioning groove 43, the first cylinder 41 and the second cylinder 51 will not easily rotate relative to each other. Also, because the limiting member 54 moves into the positioning groove 43, the positioning block 42 is in contact with the inner wall of the second slide groove 53. At this time, the first cylinder 41 and the second cylinder 51 will not easily move relative to each other along their central axis, thus completing the fixation of the first cylinder 41 and the second cylinder 51 (the first disassembly structure 4 and the second disassembly structure 5). Conversely, when it is necessary to disassemble the first disassembly structure 4 and the second disassembly structure 5, simply rotate the first cylinder 41 or the second cylinder 51 in the opposite direction to make the limiting member 54 disengage from the positioning groove 43 and the positioning block 42 disengage from the second slide groove 53 and enter the first slide groove 52. Then pull the first cylinder 41 and the second cylinder 51 away from each other until the positioning block 42 is completely disengaged from the first slide groove 52. Thus, the first disassembly structure 4 and the second disassembly structure 5 can be used to achieve either a first usage state where the handle part 1 and the massage part 2 are fixedly assembled with a relatively short length, or a second usage state where the handle part 1, the bent extension part and the massage part 2 are fixedly assembled with a relatively long length.

[0023] like Figure 3 , Figure 7 , Figure 8 and Figure 9As shown, the material of the extension structure 3 is a deformable material. The extension structure 3 includes a deformable support member 31. The two ends of the deformable support member 31 can be detachably fixed to the first disassembly structure 4 and the second disassembly structure 5, respectively. Specifically, it can be fixed with screws, which is stable and easy to disassemble and assemble. The deformable support 31 here can be made of plastic bent pipe, plastic bent plate, metal bent pipe, metal bent plate, etc. Taking a plastic bent plate or metal bent plate as an example, after the deformable support 31 is in contact with the first disassembly structure 4 or the second disassembly structure 5, screws can be used to directly fix the deformable support 31 to the first disassembly structure 4 or the second disassembly structure 5. In addition, a slot 9 can be opened at one end of the first disassembly structure 4 and the second disassembly structure 5 (e.g., Figure 8 and Figure 9 As shown, after the deformable support 31 is inserted into the slot 9 for positioning, screws are used to fix the first disassembly structure 4 and the deformable support 31 or the second disassembly structure 5 and the deformable support 31 through them.

[0024] like Figure 3 and Figure 7 As shown, the extension structure 3 also includes a protective sleeve 32, which is fitted around the deformable support 31. By setting the protective sleeve 32, it serves two purposes: firstly, it can prevent external objects from directly contacting and colliding with the deformable support 31 and causing damage to it, and secondly, it can protect the human body from contacting and colliding with the deformable support 31 and causing injury to the human body. On the other hand, it can also wrap the screws to ensure the overall aesthetics.

[0025] like Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the fascia gun also includes a limiting structure to prevent the protective sleeve 32 from sliding on the deformable support 31, ensuring stable fixation between the protective sleeve 32 and the deformable support 31. Specifically, the limiting structure includes a recessed portion 8 and a protrusion 322 adapted to the recessed portion 8. The first disassembly and assembly structure 4 includes a first connecting portion 44, and the second disassembly and assembly structure 5 includes a second connecting portion 56. When the first connecting portion 44 and / or the second connecting portion 56 have at least one recessed portion 8 or a protrusion 322 on their periphery, the inner wall of the protective sleeve 32 has at least one protrusion 322 or a recessed portion 8. When the protective sleeve 32 is fitted around the deformable support member 31, the protrusion 322 is located inside the recessed portion 8. Taking the example of a recessed portion 8 on the outer wall of the first connecting portion 44 and the second connecting portion 56, and a protrusion 322 on the inner wall of the protective sleeve 32, when the protective sleeve 32 is fitted around the deformable support member 31, the engagement between the protrusion 322 and the recessed portion 8 ensures that the protective sleeve 32 will not slide freely on the deformable support member 31.

[0026] like Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the limiting structure includes a stepped surface (specifically, such as...). Figure 8 The first step surface 441 and Figure 9 The protective sleeve 32 has an opening at both ends and has several inner edges 321 extending toward the center of the opening. When the protective sleeve 32 is fitted around the deformable support 31, each inner edge 321 abuts against a step surface, so that the protective sleeve 32 can be limited by the protrusion 322 and the recess 8 alone or in combination, so that the protective sleeve 32 will not slide arbitrarily on the deformable support 31.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
