Description

Technical Field

[0001] The present invention relates to the technical field of fascia guns, and in particular to a novel fascia gun. Background Art

[0002] With the rapid development of science and technology, there are more and more massage devices, such as fascia guns, also known as deep myofascial impactors. Fascia guns are a soft tissue rehabilitation tool that uses a special internal high-speed motor to drive the "gun head" to produce high-frequency vibrations, acting on the skin, fat, fascia and muscles, aiming to reduce local tissue tension, relieve pain and promote blood circulation. Fascia guns were originally used mainly as sports rehabilitation equipment, and are now widely used to relax muscles and relieve fatigue. At present, the transmission method used by fascia guns on the market is that there is a certain distance between the axis of the motor shaft and the axis of the eccentric wheel, and then there is an eccentricity. When the motor drives the motor shaft to rotate, the motor shaft drives the eccentric wheel to make a circular motion. Due to the eccentricity between the eccentric shaft and the motor shaft, the eccentric shaft drives the connecting rod to reciprocate. Due to the limitations of this method, the fascia guns on the market are all "7-shaped" or "T-shaped", and this transmission method causes the motor to be a certain distance from the eccentric wheel, and the eccentric wheel to the connecting rod. The distance between the motor shaft and the connecting rod is too large, and the overall volume of the fascia gun cannot be reduced. Summary of the invention

[0003] The purpose of the present invention is to provide a new type of fascia gun to solve the problem that the volume of the fascia gun cannot be reduced. The present invention provides a new type of fascia gun, including a housing, a drive motor, a transmission assembly and a massage assembly, the transmission assembly including an eccentric wheel, a connecting rod, a bearing and a sliding bearing, a fixed disk is arranged below the drive motor, the motor shaft of the drive motor is movably connected to the fixed disk, a clamping coupling is arranged on the eccentric wheel, a mounting groove for accommodating a housing of the drive motor is arranged inside the eccentric wheel, the housing is arranged in the mounting groove, the clamping coupling locks and fixes the housing, the bearing is arranged at one end of the connecting rod close to the eccentric wheel, and the eccentric wheel is fixedly connected to the connecting rod through the bearing.

[0004] A new type of fascia gun provided according to the present invention also includes a sliding bearing arranged outside the connecting rod, a sleeve arranged outside the sliding bearing, a silicone sleeve wrapped outside the sleeve, and batteries arranged on both sides of the silicone sleeve.

[0005] According to a new type of fascia gun provided by the present invention, three first screw holes are arranged on the fixing plate, and the fixing plate is fixedly connected to the shell by screws.

[0006] According to a new type of fascia gun provided by the present invention, one end of the motor shaft is connected to the eccentric wheel and can rotate relatively, and the axis of the housing and the axis of the eccentric wheel are not located on the same central axis.

[0007] A new fascia gun provided according to the present invention also includes three second screw holes arranged on one end of the connecting rod near the bearing, the side of the casing near the fixed plate is flush with one side of the connecting rod, and one side of the connecting rod is flush with one side of the bearing, and the casing is fixed in the mounting groove by inserting screws into the three second screw holes on the side of the connecting rod near the fixed plate through a card.

[0008] According to a new type of fascia gun provided by the present invention, the end of the connecting rod away from the eccentric wheel is fixedly connected to the sliding bearing through a pin, a sleeve is arranged on the outside of the sliding bearing, and the silicone sleeve wraps the sleeve and is tightly attached to the sliding bearing.

[0009] A novel fascia gun provided according to the present invention also includes the massage component being clamped together with the sliding bearing.

[0010] A new type of fascia gun provided according to the present invention also includes the clamping coupling that locks and fixes the casing by installing vertical screws.

[0011] The present invention utilizes the casing of the driving motor and the eccentric wheel to cooperate with each other to transmit power, and cleverly embeds the casing of the driving motor into the eccentric wheel, which not only ensures the driving of the fascia gun, but also overlaps the space occupied by the casing and the eccentric wheel, thereby reducing the overall required space. In this way, the connecting rod is arranged on the outside of the eccentric wheel through the rotating shaft, and the thickness of the overall transmission structure is reduced to be equal to the thickness of the eccentric wheel, so that the overall volume of the fascia gun is reduced, and it can adapt to shells of more shapes, thereby improving the utilization of space.

[0022] See attached Figure 1 To Attachment Figure 3 , shown in the figure is a specific embodiment of a new type of fascia gun provided by the present invention.

[0023] See attached Figure 1 A new type of fascia gun comprises a shell, a driving motor 2, a transmission assembly and a massage assembly 9, wherein the transmission assembly comprises an eccentric wheel 5, a connecting rod 3, a bearing 4 and a sliding bearing 6, a fixed disk 1 is arranged below the driving motor 2, a motor shaft 202 of the driving motor 2 is movably connected with the fixed disk 1, a clamping coupling 501 is arranged on the eccentric wheel 5, a mounting groove 502 for accommodating a housing 201 of the driving motor 2 is arranged inside the eccentric wheel 5, the housing 201 is arranged in the mounting groove 502, the clamping coupling 501 locks and fixes the housing 201, the bearing 4 is arranged at one end of the connecting rod 3 close to the eccentric wheel 5, and the eccentric wheel 5 is fixedly connected to the connecting rod 3 through the bearing 4.

[0024] See attached Figure 1 In the above embodiment, a sliding bearing 6 is arranged outside the connecting rod 3, a sleeve 7 is arranged outside the sliding bearing 6, a silicone sleeve 8 is wrapped outside the sleeve 7, and batteries are arranged on both sides of the silicone sleeve 8. By designing the battery in this way, the empty space on both sides of the silicone sleeve 8 is cleverly utilized, the occupied space is further reduced, and the space utilization rate is improved.

[0025] See attached Figure 3 In the above embodiment, three first screw holes 101 are provided on the fixing plate 1, and the fixing plate 1 is fixedly connected to the housing by screws. The transmission structure is fixed to the housing by the fixing plate 1 using the screw holes and screws, thereby increasing the stability of the device.

[0026] See attached Figure 3 In the above embodiment, one end of the motor shaft 202 is connected to the eccentric wheel 5 and can rotate relatively. The axis of the housing 201 and the axis of the eccentric wheel 5 are not located on the same central axis. Through the operation of the driving motor 2, the housing 201 is driven to perform circular motion. The axis of the housing 201 and the axis of the eccentric wheel 5 are not located on the same central axis, thereby generating an eccentricity, causing the connecting rod 3 to reciprocate.

[0027] See attached Figure 2 In the above embodiment, three second screw holes 301 are provided at one end of the connecting rod 3 close to the bearing 4, the side of the housing 201 close to the fixed plate 1 is flush with the side of the connecting rod 3, and the side of the connecting rod 3 is flush with the side of the bearing 4. The side of the connecting rod 3 close to the fixed plate 1 is screwed into the three second screw holes 301 through a card to fix the housing 201 in the mounting groove 502. The housing 201 is placed in the mounting groove 502 so that it is flush with one side of the connecting rod 3, and then the housing 201 can be well fixed in the mounting groove 502 by using a card to insert screws into the three second screw holes 301, thereby improving the stability of the device.

[0028] See attached Figure 1 In the above embodiment, one end of the connecting rod 3 away from the eccentric wheel 5 is fixedly connected to the sliding bearing 6 through a pin, and a sleeve 7 is provided on the outside of the sliding bearing 6. The silicone sleeve 8 wraps the sleeve 7 and is tightly attached to the sliding bearing 6. The pin and the silicone sleeve 8 are used for assembly, which can effectively avoid the problem of mechanical movement not being consistent with the assumption due to errors during the assembly and manufacturing process. The silicone sleeve 8 can buffer excessive force and adjust the movement direction by itself, thereby reducing the requirements for assembly and production.

[0029] See attached Figure 1In the above embodiment, the massage component 9 is snap-connected with the sliding bearing 6. By setting the massage component 9 and the sliding bearing 6 in a snap-connected manner, the user can easily replace the massage component 9 with other styles during use, thereby increasing the user's diversified massage experience and improving the user's usage experience.

[0030] See attached Figure 3 In the above embodiment, the clamping coupling 501 locks and fixes the casing 201 by installing vertical screws. In this way, while ensuring that the casing 201 is fixed, the casing 201 can also be protected without affecting the center concentricity of the casing 201 and the eccentric wheel 5, so that the operation is smooth and no swing occurs.

[0031] The beneficial effect of the present invention is as follows: by utilizing the casing 201 of the driving motor 2 and the eccentric wheel 5 to cooperate with each other to transmit power, the casing 201 of the driving motor 2 is cleverly embedded in the eccentric wheel 5, which not only ensures the driving of the fascia gun, but also overlaps the space occupied by the casing 201 and the eccentric wheel 5, thereby reducing the overall required space. In this way, the connecting rod 3 is arranged on the outside of the eccentric wheel 5 through the rotating shaft, and the thickness of the overall transmission structure is reduced to be equivalent to the thickness of the eccentric wheel 5, so that the overall volume of the fascia gun is reduced, and it can adapt to shells of more shapes, thereby improving the utilization of space.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features thereof may be replaced by equivalents.
