Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric fascia guns, in particular to an electric fascia gun with self-adaptive mechanical force. BACKGROUND

[0002] A fascia gun, also known as a deep muscle fascia impact instrument, is a portable device that relaxes soft tissues, relieves muscle soreness and promotes blood circulation through high-frequency, short-stroke mechanical impact. Its working principle is usually to drive an eccentric wheel by a motor to convert rotary motion into reciprocating linear motion, thereby driving the massage head to perform high-frequency tapping on the target muscle group.

[0003] With the popularity of fascia guns, users have increasingly high requirements for their functions and performance. Although traditional electric fascia guns can provide effective relaxation, their impact force is usually fixed or pre-set through limited electronic speed regulation. This working mode has a significant defect, i.e., it cannot dynamically and adaptively adjust the force feedback according to the pressing force during actual use.

[0004] In actual use, the body parts, muscle tension and personal tolerance of users are different. For example, a larger impact force may be needed to achieve deep relaxation for muscle-rich areas such as thighs and hips, while a gentle force is needed for sensitive and weak areas such as the neck and joints. The existing fascia gun requires users to manually switch gears to adapt to different parts, which disrupts the continuity of massage and relies on the subjective judgment of users, making the operation less intelligent and convenient. More importantly, when users apply different pressing forces to the same part, the output stroke and force of the traditional fascia gun are constant.

[0005] Therefore, there is an urgent need in the art for a fascia gun that can intelligently sense the user's pressing force and automatically adjust the striking force in real time. Although there are some existing solutions that attempt to solve this problem, such as adjusting the motor speed or current through pressure sensors and complex electronic control systems, these solutions often have complex structures, high costs, delayed responses, and unreliable reliability in the continuous high-frequency vibration environment. In view of this, the present application aims to provide an electric fascia gun with pure mechanical and self-adaptive force adjustment. This design discards the complex electronic control system and converts the user's hand pressure on the device directly and without delay into the increase of the eccentricity of the impact assembly, thereby linearly increasing the stroke and striking force of the working end. SUMMARY

[0006] In view of the above technical problems, the technical scheme adopted by the present application is: an electric fascia gun with self-adaptive mechanical force, which comprises a main mechanism for relaxing fascia of a patient part or a part needing relaxation, wherein the main mechanism comprises a fascia gun shell, a self-adjusting mechanism for adjusting great force according to different pressing forces is arranged on the main mechanism, and the self-adjusting mechanism comprises a fixed cylinder fixedly installed in the fascia gun shell.

[0007] Further, the main mechanism comprises an inner sliding column slidingly installed in the fascia gun shell, an operation end fixedly installed on the inner sliding column, and an eccentric rotating arm rotatably installed on the inner sliding column.

[0008] Further, the main mechanism further comprises a side rotating column rotatably installed on the fixed cylinder, a side gear fixedly installed on the side rotating column, a rotating rod fixedly installed on the side rotating column, a horizontal sliding groove arranged in the rotating rod and eccentric to the center of the side rotating column, a horizontal moving ring slidingly installed in the horizontal sliding groove, a spring arranged between the horizontal moving ring and the rotating rod, a sliding column fixedly installed in the horizontal moving ring, a rotating block fixedly installed on the sliding column, and the eccentric rotating arm and the rotating block are rotatably installed.

[0009] Further, the main mechanism further comprises an inner motor fixedly installed in the fascia gun shell, a motor wheel fixedly installed on a motor shaft of the inner motor, an inner transmission wheel rotatably installed in the fascia gun shell, an inner gear fixedly installed on the inner transmission wheel, and an inner transmission belt wound outside the inner transmission wheel and the motor wheel, and the inner gear is engaged with the side gear.

[0010] The inner motor drives the motor wheel to rotate, the motor wheel drives the inner transmission wheel to rotate through the inner transmission belt, the inner transmission wheel drives the inner gear to rotate, the inner gear drives the side gear, the side rotating column and the rotating rod to rotate, the rotating rod drives the horizontal moving ring, the sliding column and the eccentric rotating arm to rotate eccentrically relative to the rotating rod and the side rotating column through the horizontal sliding groove, so as to drive the inner sliding column and the operation end to slide back and forth relative to the fascia gun shell rapidly through the eccentric rotating arm.

[0011] The user can replace the operation end with different shapes according to different use requirements, and when using, first turn on the power, hold the handle, power the inner motor through the battery pack, place the operation end on the fascia of the part needing massage or relaxation, and continuously impact the fascia through the rapid reciprocating sliding of the operation end and the inner sliding column relative to the fascia gun shell to achieve the purpose of massage and relaxation.

[0012] Further, the self-adjusting mechanism comprises an outer sliding sleeve slidingly installed on the fascia gun shell, an inner connecting block fixedly installed on the outer sliding sleeve, two inclined groove plates fixedly installed on the inner connecting block, an inclined sliding groove arranged on the inclined groove plate, and the inclined groove plate slides in the fixed cylinder.

[0013] Further, the self-adjusting mechanism further comprises a lifting column slidingly installed in the fixed cylinder, a lifting cone head being fixedly installed above the lifting column, the upper surface of the lifting cone head being a conical surface, the lifting column being located between the two inclined chute plates, and side guide columns being arranged on both sides of the lifting column and sliding in the inclined sliding grooves.

[0014] Further, the self-adjusting mechanism further comprises an outer pushing column fixedly installed on the sliding column, the outer pushing column being slidingly installed with the side rotating column, and the end of the outer pushing column being in contact with the conical surface of the lifting cone head.

[0015] Further, the self-adjusting mechanism further comprises a fixed ring fixedly installed on the fascia gun shell, a handle being fixedly installed below the outer sliding sleeve, and a return spring being arranged between the outer sliding sleeve and the fixed ring.

[0016] When the work end has contacted the skin of the user, and the user continues to exert force on the massage part by holding the handle, the outer sliding sleeve slides relative to the fixed ring, the return spring is compressed, and the outer sliding sleeve moves towards the work end, at this time, the outer sliding sleeve drives the inner connecting block and the inclined chute plate to move towards the work end.

[0017] The inclined chute plate drives the side guide column, the lifting column and the lifting cone head to rise through the inclined sliding grooves, the outer pushing column, the sliding column and the horizontal moving ring are pushed outwards through the conical surface of the lifting cone head, so that the eccentric distance of the sliding column relative to the side rotating column and the rotating rod is increased, at this time, the movement stroke of the eccentric rotating arm is increased, and the impact force of the work end is increased, so as to realize that the greater the force exerted by the user on the skin, the greater the impact force of the work end.

[0018] When the side rotating column and the rotating rod rotate, the outer pushing column slides on the conical surface of the lifting cone head, so that the outer pushing column, the sliding column and the horizontal moving ring are always pushed outwards by the conical surface of the lifting cone head during the rotation of the side rotating column and the rotating rod.

[0019] Further, the fascia gun shell is fixedly installed with an outer protective sleeve, the inner sliding column is located in the outer protective sleeve, and the end of the fascia gun shell is provided with a battery pack for supplying power to the built-in motor.

[0020] Further, the work end is detachable and replaceable, and there are three types of work ends, namely, a spherical shape, a fork shape and a disc shape.

[0021] The beneficial effects of this invention compared with the prior art are: (1) This invention directly and in real time converts the pressure of the user's hand into an increase in the impact force at the end of the work by means of a mechanical self-adjustment mechanism. When the user presses down, the displacement of the outer sliding sleeve pushes the sliding column outward without delay through the inclined plate and the lifting cone, increasing the eccentricity of the transmission system, thereby linearly increasing the stroke and impact force at the end of the work. It can provide precise force feedback according to different body parts and muscle states, which not only avoids the poor relaxation effect caused by insufficient force, but also prevents damage that may be caused by excessive impact in sensitive areas; (2) The self-adjustment process set by this invention is completely realized through a pure mechanical structure, without relying on electronic sensors that are susceptible to vibration interference, complex control circuits or software algorithms. The mechanical linkage mechanism is directly integrated into the transmission system, with a compact structure and a short power transmission path, which not only avoids the The invention addresses the issue of electronic system response delay and improves reliability and durability in continuous high-frequency vibration environments, reducing potential failures of electronic components and extending the overall lifespan of the product; (3) This invention eliminates the need for users to frequently switch gears manually or consult complex instructions. Users can simply press down the handle naturally, just like using a traditional tool, and the device will automatically provide the appropriate impact force, making operation simple and intuitive and enhancing the continuity and immersion of the massage process; (4) While realizing the core adaptive function, this invention retains good versatility. The device end is designed as a detachable and replaceable working end, which can be adapted to various massage heads such as spherical, fork-shaped, and disc-shaped to meet different massage needs such as impact, pressing, and vibration. Its adaptive force adjustment mechanism can work in conjunction with working ends of various shapes, ensuring effectiveness and safety in different application scenarios. Attached Figure Description

Detailed Implementation

[0031] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0032] Example: Reference Figures 1-8 An electric fascia gun with adaptive mechanical force includes a main body mechanism for relaxing the fascia of the affected area or the area that needs relaxation. The main body mechanism includes a fascia gun housing 101 and is provided with a self-adjusting mechanism that adjusts the force according to different pressure levels. The self-adjusting mechanism includes a fixed cylinder 208 fixedly installed inside the fascia gun housing 101.

[0034] like Figures 2-4 As shown, the main mechanism also includes a side rotating column 111 rotatably mounted on the fixed cylinder 208. A side gear 112 is fixedly mounted on the side rotating column 111. A rotating rod 113 is fixedly mounted on the side rotating column 111. A transverse sliding groove 117 is provided inside the rotating rod 113. The transverse sliding groove 117 is eccentrically positioned relative to the center of the side rotating column 111. A transverse moving ring 118 is slidably mounted inside the transverse sliding groove 117. A spring is provided between the transverse moving ring 118 and the rotating rod 113. A sliding column 114 is fixedly mounted inside the transverse moving ring 118. A rotating block 116 is fixedly mounted on the sliding column 114. An eccentric rotating arm 115 is rotatably mounted on the rotating block 116.

[0035] like Figures 2-4 As shown, the main mechanism also includes a built-in motor 103 fixedly installed inside the fascia gun housing 101. A motor wheel 107 is fixedly installed on the motor shaft of the built-in motor 103. An inner transmission wheel 109 is rotatably installed inside the fascia gun housing 101. An inner gear 110 is fixedly installed on the inner transmission wheel 109. An inner transmission belt 108 is wound around the inner transmission wheel 109 and the motor wheel 107. The inner gear 110 meshes with the side gear 112.

[0036] The built-in motor 103 drives the motor wheel 107 to rotate. The motor wheel 107 drives the inner transmission wheel 109 to rotate through the inner transmission belt 108. The inner transmission wheel 109 drives the inner gear 110 to rotate. The inner gear 110 drives the side gear 112, the side rotating column 111, and the rotating rod 113 to rotate. The rotation of the rotating rod 113 drives the transverse moving ring 118, the sliding column 114, and the eccentric rotating arm 115 to rotate eccentrically relative to the rotating rod 113 and the side rotating column 111 through the transverse sliding groove 117. Thus, the eccentric rotating arm 115 drives the inner sliding column 104 and the working end 105 to slide rapidly back and forth relative to the fascia gun housing 101.

[0037] Users can replace the working end 105 with different shapes according to different usage needs. When using it, first turn on the power, hold the handle 204, and use the battery pack 102 to power the built-in motor 103. Place the working end 105 on the fascia of the area that needs to be massaged or relaxed. Through the rapid reciprocating sliding of the working end 105 and the inner sliding column 104 relative to the fascia gun shell 101, the fascia is continuously impacted to achieve the purpose of massage and relaxation.

[0038] like Figures 5-8 As shown, the self-adjusting mechanism includes an outer sliding sleeve 203 that is slidably mounted on the fascia gun housing 101. An inner connecting block 205 is fixedly mounted on the outer sliding sleeve 203. Two inclined groove plates 207 are fixedly mounted on the inner connecting block 205. Inclined grooves 212 are provided on the inclined groove plates 207. The inclined groove plates 207 slide within the fixed cylinder 208.

[0039] like Figures 5-8 As shown, the self-adjusting mechanism also includes a lifting column 209 that is slidably installed in the fixed cylinder 208. A lifting cone 210 is fixedly installed above the lifting column 209. The upper surface of the lifting cone 210 is a conical surface. The lifting column 209 is located between two inclined slot plates 207. Side guide columns 206 are provided on both sides of the lifting column 209. The side guide columns 206 slide in the inclined slide groove 212.

[0040] like Figures 5-8 As shown, the self-adjusting mechanism also includes an outward push column 211 fixedly installed on the sliding column 114. The outward push column 211 is slidably installed with the side rotating column 111, and the end of the outward push column 211 contacts the conical surface of the lifting cone head 210.

[0041] As Figures 5-8 shown, the self-adjusting mechanism further comprises a fixed ring 201 fixedly installed on the fascia gun shell 101, a handle 204 fixedly installed below an outer sliding sleeve 203, and a return spring 202 arranged between the outer sliding sleeve 203 and the fixed ring 201.

[0042] In use, when the working end 105 has contacted the skin of the user, the user continues to exert force on the handle 204 towards the massage site, which causes the outer sliding sleeve 203 to slide relative to the fixed ring 201, the return spring 202 is compressed, and the outer sliding sleeve 203 moves towards the working end 105, at this time, the outer sliding sleeve 203 drives the inner connecting block 205 and the inclined chute plate 207 to move towards the working end 105.

[0043] The inclined chute plate 207 drives the side guide column 206, the lifting column 209 and the lifting cone head 210 to rise through the inclined sliding groove 212, and the outer push column 211, the sliding column 114 and the horizontal moving ring 118 are driven to move outward through the taper surface of the lifting cone head 210, so that the eccentric distance of the sliding column 114 relative to the side rotating column 111 and the rotating rod 113 is increased, at this time, the movement stroke of the eccentric rotating arm 115 is increased, and the impact force of the working end 105 is increased, so that the greater the force exerted by the user on the skin, the greater the impact force of the working end 105.

[0044] When the side rotating column 111 and the rotating rod 113 rotate, the outer push column 211 slides on the taper surface of the lifting cone head 210, so that the taper surface of the lifting cone head 210 always pushes the outer push column 211, the sliding column 114 and the horizontal moving ring 118 outward during the rotation of the side rotating column 111 and the rotating rod 113.

[0045] As Figures 2-4 shown, the fascia gun shell 101 is fixedly installed with an outer protective sleeve 106, the inner sliding column 104 is located in the outer protective sleeve 106, and the fascia gun shell 101 is provided with a battery pack 102 for supplying power to the built-in motor 103.

[0046] As Figures 2-4 shown, the working end 105 is detachable and replaceable, and the working end 105 has three types, namely a spherical type, a fork type and a disc type.

[0047] The working principle of the self-adaptive mechanical force electric fascia gun disclosed by the application is as follows: a user can replace the working end 105 with different shapes according to different use requirements; when in use, the power is first turned on, the handle 204 is held, the working end 105 is placed on the fascia of a part needing massage or relaxation, the working end 105 and the inner sliding column 104 are quickly reciprocated relative to the fascia gun shell 101 to impact the fascia continuously, and the purpose of massage and relaxation is achieved. The built-in motor 103 drives the motor wheel 107 to rotate, the motor wheel 107 drives the inner transmission wheel 109 to rotate through the inner transmission belt 108, the inner transmission wheel 109 drives the inner gear 110 to rotate, the inner gear 110 drives the side gear 112, the side rotating column 111 and the rotating rod 113 to rotate, the rotating rod 113 rotates to drive the horizontal sliding groove 117, the horizontal moving ring 118, the sliding column 114 and the eccentric rotating arm 115 to rotate eccentrically relative to the rotating rod 113 and the side rotating column 111, so that the inner sliding column 104 and the working end 105 are driven by the eccentric rotating arm 115 to slide quickly relative to the fascia gun shell 101.

[0048] When in use, after the working end 105 has contacted the skin of the user, the handle 204 is held to continue to exert force on the massage part, the outer sliding sleeve 203 slides relative to the fixed ring 201, the reset spring 202 is compressed, the outer sliding sleeve 203 moves towards the working end 105, and the outer sliding sleeve 203 drives the inner connecting block 205 and the inclined groove plate 207 to move towards the working end 105. The inclined groove plate 207 drives the side guide column 206, the lifting column 209 and the lifting cone head 210 to rise through the inclined sliding groove 212, the outer push column 211, the sliding column 114 and the horizontal moving ring 118 are driven to move outward by the taper surface of the lifting cone head 210, the eccentric distance of the sliding column 114 relative to the side rotating column 111 and the rotating rod 113 is increased, the movement stroke of the eccentric rotating arm 115 is increased at this time, and the impact force of the working end 105 is increased, so that the impact force of the working end 105 is increased when the user presses the skin more.

[0049] When the side rotating column 111 and the rotating rod 113 rotate, the outer push column 211 slides on the taper surface of the lifting cone head 210, so that the taper surface of the lifting cone head 210 always pushes the outer push column 211, the sliding column 114 and the horizontal moving ring 118 outward during the rotation of the side rotating column 111 and the rotating rod 113.

[0050] The above merely describes the preferred specific embodiments of the application, but the protection scope of the application is not limited to this. Any person skilled in the art can make equivalent replacements or changes to the technical solution and the inventive concept of the application within the technical scope of the application, which should be covered within the protection scope of the application.
