The technical solution of the present application will be further described with reference to the following embodiments and accompanying drawings.

As shown in fig. 1, 2 and 4, an embodiment of the present application provides a fascia gun, which includes a body 1, a massage head 2, a handle 3 and a motor assembly; the fuselage 1 includes a nose portion 11, a tail portion 12 and a fuselage body 13 connected between the nose portion 11 and the tail portion 12, that is, the fuselage 1 has a length extending direction from the nose portion 11 to the tail portion 12, that is, an x direction in fig. 1. The massage head 2 is arranged at the head part 11 of the machine body 1 and is used for massaging the human body; the handle 3 is arranged at one side of the machine body 1 (i.e. the handle 3 is arranged below the machine body 1 as shown in fig. 1) and is used for facilitating a user to hold the handle 3 by hand so as to realize the effect of holding the fascial gun by hand to massage the part of the user needing massage.

In the related art, because the handle is in a straight cylinder shape and the lengths of the fingers of the user are different, the holding comfort level of the user when holding the handle is not good; in the embodiment, the free portion 31 of the handle 3 is arranged toward the connecting portion 32 connected to the body 1 (i.e., from bottom to top), and the cross-sectional area p of the connecting portion 32 is gradually increased (the cross-sectional area here refers to the area enclosed by the outer contour of the handle 3) so that the outer surface of the connecting portion 32 forms a limiting slope m, the limiting slope m is used for increasing the attaching area between the user's hand and the handle 3 and preventing the user's hand from moving toward the body 1, and under the same anti-moving friction force, the holding force of the user's hand is effectively reduced, so that the user can hold the gun fascia more easily; and the limit inclined plane m can limit the hand of the user from moving towards the machine body 1, so that the situation that the bottom surface of the machine body 1 presses the lateral surfaces of the forefinger and the thumb can be effectively avoided, and the fatigue of the long-time fascia gun is reduced. It will be appreciated that the cross-sectional area p is the cross-sectional area of the handle 3 along a plane perpendicular to the direction of the free portion 31 of the handle 3 towards the connecting portion 32 with the body 1. As shown in fig. 1, the cross-sectional area p of the connecting portion 32 increases gradually from bottom to top, which can effectively prevent the user's hand from moving toward the main body 1 on the handle 3; meanwhile, the shape of the handle 3 also conforms to the shape of a hand when the handle is held by the hand, namely the finger ring enclosed by the forefinger of the user is smaller than the finger ring enclosed by the fingers and is larger, so that the user can not feel tired even when holding the handle 3 by hand for a long time.

Specifically, the limit inclined plane m is in the shape of an inwards concave arc surface and is connected to the machine body 1 in a smooth transition mode. Because handle 3 passes through connecting portion 32 and is connected with fuselage 1, can eliminate effectively between connecting portion 32 and the fuselage 1, because of the produced sharp limit of handing-over of dimensional change between connecting portion 32 and the handle 3 through setting spacing inclined plane m to the cambered surface, avoid because of there being the problem that the sharp change leads to the chrome hand.

More specifically, the head part 11 and the tail part 12 are both protruded out of the outer edge of the handle 3, and the limit inclined plane m smoothly transits to the side of the tail part 12 opposite to the massage head 2. Through all setting up prelude 11 and afterbody 12 to protrusion in handle 3's outside edge promptly, can make to form the spacing inclined plane m that encircles between handle 3 and the fuselage 1, and then the department of transition between handle 3 and fuselage 1 forms the spacing inclined plane m that encircles in order to carry out the omnidirectional limiting displacement to user's hand for spacing inclined plane m is more even to the spacing atress of user's hand, and then makes anti-channeling effect better.

In addition, the fascial gun also comprises a motor assembly 4, at least part of the motor assembly 4 is arranged in the handle 3 to increase the balance weight of the handle 3, so that the inertia of the handle 3 is increased, the vibration of the handle 3 is smaller, and the relative movement of the handle 3 and the hand is further prevented; in addition when the handheld handle 3 of standing vertically, the bigger handle 3 of gravity can order about spacing inclined plane and press to paste to the hand, avoided the hand to keeping away from 1 one side drunkenness of fuselage effectively from this, so set up through spacing inclined plane m and the gravity distribution of handle 3 sets up the combined action, prevented the drunkenness of hand on handle 3 effectively, and reduced the dynamics demand of gripping, avoided the oppression of fuselage 1 to the finger, make the user hold for a long time when holding handle 3 not tired and the hand highly stable that grips on handle 3.

Specifically, motor element 4 can be selected for use and have brush motor or brushless motor, and its specific size model can be selected for use according to actual massage dynamics demand, and this embodiment does not do specific limit to this.

The fascia gun also comprises a transmission component 5 and a piston 6, wherein the transmission component 5 and the piston 6 are positioned in the machine body 1, the transmission component 5 extends towards one side close to the handle 3 to be connected with the motor component 4, the motor component 4 drives the piston 6 to do reciprocating linear motion through the transmission component 5, and the piston 6 is connected with the massage head 2; the axial direction of the motor assembly 4 is deflected towards the tail portion 12 relative to the extension direction of the handle 3. Thereby, the gravity of the handle 3 is deflected toward the tail portion 12, so that the handle 3 generates a pressing force to the palm, thereby making the holding more labor-saving. In addition, because the axis of the piston 6 is perpendicular to the axis of the motor assembly 4, the included angle between the axis of the piston 6 and the extending direction of the handle 3 is an obtuse angle, so that the bending degree of the wrist can be reduced when the fascial gun is used, and the fatigue of long-term holding is reduced.

As shown in fig. 1, the head 11, the tail 12 and the main body 13 are integrally formed into the body 1 with a smooth outer surface, so that the body 1 is a smooth 3D curved surface, and the problem of inconvenience in cleaning due to dead angles existing on the body 1 is avoided. Namely, the fascia gun of the embodiment has a smooth overall appearance, and is convenient and labor-saving to clean. It should be noted that, as shown in fig. 1 and fig. 2, the head part 11 is a left part of the main body 11, the tail part 12 is a right part of the main body 13, and the massage head 2 is disposed on the left side of the main body 1 and connected to the head part 11 located on the left side of the main body 13. Similarly, the free portion 31, the connecting portion 32 and the handle body 33 are integrally formed into the handle 3 with a smooth outer surface, so that the handle 3 integrally presents a smooth 3D curved surface.

As shown in fig. 7 and 8, the boundary between the handle 3 and the body 1 is a, and it should be noted that since the connecting portion between the body 1 and the handle is in smooth transition, there is no obvious boundary and only a rough distinction can be made, and the boundary a is only illustrated for the sake of clearer understanding of the present embodiment, and is not a boundary position in an absolute sense.

In addition, in this embodiment, the handle 3 is configured to have a free portion 31, a connecting portion 32 and a handle main body 33 connected between the free portion 31 and the connecting portion 32, that is, a portion convenient for a user to hold is the handle main body 33, and a portion for connecting with the main body 13 is defined as the connecting portion 32, the connecting portion 32 can be specifically connected with the main body 13 in a clamping manner or in a threaded manner, or the connecting portion 32 and at least a portion of the main body 13 are integrally formed to save a processing process, so that the whole fascia gun gradually and smoothly transitions from the handle 3 with a small cross section to the main body 1 with a large outline without dead angles, and thus the overall appearance of the fascia gun is smoother, without dead angles, and is safer and easier. And the end of the handle 3 away from the body 13 defines a free portion 31, i.e. as shown in fig. 1, the upper end of the handle body 33 is a connecting portion 32 and the lower end is the free portion 31. More importantly, unlike the handle 3 in the related art which is in a straight cylinder shape, that is, the cross section of the handle 3 in the direction from the free portion 31 to the connecting portion 32 is uniform, this design may cause the user to feel tired when holding the handle 3, because the lengths of the five fingers of the user are different, for example, the circle diameter of the circle surrounded by the index finger and the circle surrounded by the little finger is different, and the cross section of the handle 3 is uniform, which may cause the index finger to possibly encircle the handle and the little finger to possibly not completely encircle the handle, and thus may cause the user to feel tired when holding the handle. Therefore, in order to conform to the shape of the human hand when making a fist, so that the user feels comfortable when holding the handle, in the present embodiment, the handle 3 is configured to be arranged in a direction from the free portion 31 toward the connecting portion 32 (i.e., a direction from bottom to top), the cross-sectional area p of the connecting portion 32 gradually increases, and the specific increasing change of the gradually increasing cross-sectional area of the connecting portion 32 is set according to actual needs, which is not specifically limited in the present embodiment.

Further, as shown in fig. 4-1 and 4-2, the handle 3 is provided with a handle inner cavity 36, the body 1 is provided with a body inner cavity 15, and the handle inner cavity 36 is communicated with the body inner cavity 15; the transmission assembly 5 is positioned in the inner cavity 15 of the fuselage and extends along the tail part 12 towards the head part 11; part of motor element 4 is located in fuselage inner chamber 15, and remaining part motor element 4 is located handle inner chamber 36 to be used for making handle inner chamber 36 and fuselage inner chamber 15 communicate and be used for placing motor element 4 and transmission assembly 5. It should be noted that, part of the motor assembly 4 is disposed in the handle inner cavity 36, and because the cross section of the part of the housing of the handle 3 forming the handle inner cavity 36 in the direction from the free portion 31 to the connecting portion 32 is gradually increased, when the motor assembly 4 located in the handle inner cavity 36 vibrates at a high frequency, the distance between the motor assembly 4 and the inner wall of the handle 3 is gradually increased, so as to weaken the vibration force transmitted from the high frequency vibration generated by the motor assembly 4 to the handle 3, and thus, a user can easily hold the handle 3 with a smaller force.

Specifically, the handle 3 is arranged in a direction from the free portion 31 to the connecting portion 32 (i.e. from bottom to top), and the cross-sectional area p of the connecting portion 32 is gradually increased, so that the hand of the user can be effectively prevented from moving on the handle in a direction towards the body; and motor element 4 locates in handle 3, and in the direction of connecting portion 32 of being connected with fuselage 1 of free portion 31 orientation of handle 3, the cross-sectional area of its connecting portion 32 crescent, make motor element 4 who is located in handle 3 when high-frequency vibration, the distance between the inner wall of motor element 4 distance handle 3 crescent, in order to weaken the vibrational force of high-frequency vibration that motor element 4 produced to handle 3 transmission, thereby make the user can use littleer power to easily grip handle 3, avoid transmitting 3 on the handle in a large number because of the vibration that motor element 4 produced promptly, make the user need great strength to hold handle 3 for a long time and then can produce the tired sense of feeling when making the user hold handle 3, the comfort level of gripping when leading to the user to use the manadesma rifle is not good.

As shown in fig. 1, the transition junction of the connection portion 32 and the body 1 is in smooth transition, that is, as shown in fig. 1, the handle 3 and the head portion 11 are in smooth transition, and the handle 3 and the tail portion 12 are also in smooth transition, and the connection of the whole handle 3 and the body 1 is in smooth transition, that is, the body 1 can be set to be in smooth curved with the body 1 itself of the handle 3 and the handle 3 itself, so that the external contour of the fascial gun is more smooth, and further the whole fascial gun has stronger stereoscopic impression, so that a user can observe a more visual and stereoscopic fascial gun shape in the axial direction of the body 1, and can conveniently observe and clearly fascial gun without turning over the fascial gun. The exterior of the fascial gun is more smoothly contoured, and the fascial gun can be held by a user at any position on the handle 3 for a more comfortable experience. In addition, because the connecting part 32 and the fuselage 1 form smooth transition, when the fascia gun is placed on a supporting surface like a table top, the contact area between the fascia gun and the table top is small, and the dirty resistance of the fascia gun is good.

As shown in fig. 1 and 2, the connecting portion 32 is connected to one side of the head portion 11, the body main body 13 and the tail portion 12, and both ends of the body 1 protrude from both sides of the handle 3 in a direction from the head portion 11 to the tail portion 12, so that the body 1 can limit the hand of the user. It can be understood that, as shown in the x direction in fig. 1, since both ends of the body 1 protrude out of the handle 3, a limiting surface is formed at the transition joint between the body 1 and the handle 3, specifically, a limiting surface is formed between the body 1 and the connecting portion 32, so that the limiting surface can limit the hand of the user, and the hand of the user can be prevented from moving back and forth on the handle 3 when the user holds the handle 3, so as to affect the comfort level of the user when the user holds the handle 3.

It should be noted that, as described above, the two ends of the main body 1 protrude from the handle 3 to form a step surface with the handle 3, so as to limit the hand of the user, therefore, the protruding length of the two ends of the main body 1 protruding from the handle 3 can be set according to actual needs as long as the above functions are satisfied, and this embodiment is not limited to this.

Further, as shown in fig. 1 and fig. 2, in a direction from the head portion 11 to the tail portion 12, a first arc-shaped structure S1 is formed at a transition junction between a part of the outer wall surface of the connecting portion 32 close to the head portion 11 and the fuselage 1, so that the transition junction between the part of the outer wall surface of the connecting portion 32 close to the head portion 11 and the head portion 11 is smoothly transitioned, thereby making a transition between the head portion 11 and the connecting portion 32 smooth, and making a transition connection surface between the connecting portion 32 and the head portion 11 smooth.

Further, as shown in fig. 1 and 2, a part of the outer wall surface of the connecting portion 32 near the header 11 extends toward the header 11; and from the direction of free portion 31 towards connecting portion 32, the partial outer wall face that connecting portion 32 is close to cephalad 11 extends towards the direction of keeping away from axis y of handle 3 crooked, and the outer wall face of connecting portion 32 extends towards the upper left side in order to form partial first arc structure S1, and first arc structure S1 is the flaring arc, and the tip that handle 3 is close to fuselage 1 is the arc flaring outward to make the arc transition between connecting portion 32 and cephalad 11 more smooth, make the user hold the experience that has better on handle 3 with hand.

Further, as shown in fig. 1 and fig. 2, in a direction from the head portion 11 to the tail portion 12, a second arc-shaped structure S2 is formed at a transition junction between a portion of the outer wall surface of the connecting portion 32 close to the tail portion 12 and the tail portion 12, so that the portion of the outer wall surface of the connecting portion 32 close to the tail portion 12 and the transition junction of the tail portion 12 are smoothly transitioned, and thus a transition between the tail portion 12 and the connecting portion 32 is smooth, and a connecting surface between the connecting portion 32 and the tail portion 12 is smooth.

Further, as shown in fig. 1 and 2, a part of the outer wall surface of the connecting portion 32 near the tail portion 12 extends toward the tail portion 12; and from the direction of free portion 31 towards connecting portion 32, the crooked extension of the direction of the partial outer wall face that connecting portion 32 is close to afterbody 12 towards the axis y of keeping away from handle 3 is in order to form partial second arc structure S2, and the outer wall face of connecting portion 32 extends in order to form partial second arc structure S2 towards the upper right side, and second arc structure S2 is the flaring arc, and the tip that handle 3 is close to fuselage 1 is the arc flaring outward, so that the arc transition between connecting portion 32 and afterbody 12 is more smooth, makes the user hold the better experience on handle 3.

It should be noted that, as shown in fig. 5, in the present embodiment, the curvature of the first arc-shaped structure S1 is greater than or equal to the curvature of the second arc-shaped structure S2, that is, the arc transition of the nose portion 11 is greater, and the arc transition of the tail portion 12 is smaller, so that the arc length corresponding to the bending of the nose portion 11 extending to the preset angular position is shorter than that of the tail portion 12, and therefore, the distance that the nose portion 11 protrudes from the main body 1 is shorter than that of the tail portion 12, so that the length that the nose portion 11 protrudes from the main body 1 can be indirectly reduced, the moment arm is reduced, and the user can hold the handle 3 more stably. Specifically, the curvature of the first arc-shaped structure S1 may be equal to the curvature of the second arc-shaped structure S2, so that the transition connection between the head 11 and the tail 12 of the whole fascial gun and the handle 3 is symmetrical, and the whole fascial gun line is smoother; alternatively, the bending curvature S1 of the first arc-shaped structure is greater than the bending curvature S2 of the second arc-shaped structure, and the specific difference of the bending curvatures is set according to actual needs, which is not specifically limited in this embodiment.

Further, as shown in fig. 3, the fuselage 1 has a length extension direction (refer to x direction in fig. 1) from the nose 11 toward the tail 12 and a width direction d perpendicular to the length extension direction x; along the width direction d, the machine body 1 is provided with the machine body outer side faces 14 which are oppositely arranged, the handle 3 is provided with the handle outer side faces 34 which are oppositely arranged, and smooth transition is formed between each machine body outer side face 14 and the corresponding handle outer side face 34, namely as shown in fig. 3, the transition area between each machine body outer side face 14 and the corresponding handle outer side face 34 is approximately planar, namely, the side face of the handle 3 is approximately equal to the side face of the machine body 1, so that when the fascia gun is placed on a supporting surface such as a table top, the general supporting surface is all planar, the contact area between the fascia gun and the supporting surface of the table top is large, the placement of the fascia gun on the supporting surface is more stable, and the risk of falling caused by instability is prevented.

Further, as shown in fig. 2 and 3, the handle 3 is provided with a charging hole 35, the charging hole 35 is provided on a side wall of the handle 3 near the massage head 2 or a side wall of the handle 3 far from the massage head 2, that is, as shown in fig. 2, with the fascial gun in this deployed position, the charging port 35 can be located on the left sidewall of the handle 3, or the charging port 35 can be located on the right sidewall of the handle 3, since the side of the handle 3 in the width direction (the position state as in figure 3) d is intended to be placed in contact with the support surface, while both sides of the handle 3 in the longitudinal direction (the position shown in figure 2) do not come into contact with the support surface, therefore, the problem that the charging operation is affected by the fact that the supporting surface covers the charging hole 35 when the fascia gun is stably placed cannot occur no matter the charging hole 35 is arranged on the left side wall of the handle 3 or on the right side wall of the handle 3. The specific installation position of the charging hole 35 is set according to actual needs, and this embodiment does not specifically limit this.

In other embodiments, the charging hole 35 may be disposed on an end surface of the free portion 31 away from the connecting portion 32, or the charging hole 35 may be disposed on a side wall of the handle main body 33 as close as possible to the free portion 31, so as to prevent sweat from entering the charging hole 35 when a user holds the fascial gun and holds the charging hole 35, which may cause the charging hole 35 to be easily disabled, bacteria and mildew.

Further, as shown in fig. 4-1 and 4-2, the transition connection between the inner wall surface of the handle 3 and the inner wall surface of the body 1 is in smooth transition, so that the connection transition between the handle 3 and the body 1 does not form a protrusion or a step due to the uneven shape of the inner wall surface, and the motor assembly 4 and the transmission assembly 5 are not allowed to interfere with each other.

Further, as shown in fig. 2, 4-1, 4-2, and 5, as described above, the connecting portion 32 is connected with the body 1 in a smooth transition manner, and the cross-sectional area of the connecting portion 32 or a portion of the handle 3 close to the body 1 is gradually reduced, so as to adapt to the length of the fingers of the user and improve the holding comfort; further, in addition to the gradual increase of the cross-sectional area of the handle 3 near the body 1, the cross-sectional area of the entire handle 3 may be continuously increased gradually from the free portion 31 toward the connecting portion 32, so that the user can prevent the user from feeling uncomfortable when holding the handle 3 at any position. As shown in fig. 5, fig. 5 is a schematic view illustrating a user holding the handle 3, and it can be seen that the handle 3 with the gradually increasing cross-sectional area from bottom to top is convenient for the user to hold, thereby improving the comfort of holding the handle 3.

Further, in the direction from the free portion 31 toward the connecting portion 32, the rate of change in the cross-sectional area of the free portion 31 is smaller than the rate of change in the cross-sectional area of the connecting portion 32. Namely, the change of the cross-sectional area of the connecting part 32 is faster, and the change rate of the free part 31 is smaller than that of the connecting part 32, so that on one hand, smooth transition between the handle 3 and the machine body 1 is ensured, and effective limit is formed at the jaw of the hand of the user to prevent the hand of the user from jumping back and forth on the handle 3, and the slope of the connecting part 32 is set to be larger; on the other hand, the change of the integral slope of the handle 3 can be effectively avoided, the cross section of the free end 31 of the handle 3 is small, the handle is not beneficial to holding, meanwhile, the space utilization rate in the handle 3 is reduced, and the compact design of the fascial gun is not beneficial.

As shown in fig. 6, on both sides of the handle 3 toward the head portion 11 and the tail portion 12, the slope of the free portion 31 is tan1 ° to tan3 °, and the slope of the connecting portion 32 is tan8 ° to tan15 °, i.e., the rate of change of the cross-sectional area of the free portion 31 is smaller than the rate of change of the cross-sectional area of the connecting portion 32. Specifically, the slope for the connection 32 is explained here as: since the outer contour of the connecting portion 32 changes in an arc shape, the slope of the connecting portion 32 is an inclined slope of a connecting line between an end point of the arc-shaped connecting portion 32 connected to the handle main body 33 and an end point connected to the body 1 with respect to a center line of the handle 3. Specifically, the slope of the free portion 31 may be tan1 ° as shown in fig. 6; in other embodiments, the slope of the free portion 31 may be tan2 ° or tan3 °. The slope of the connection 32 may be tan11 as shown in fig. 6; alternatively, in other embodiments, the slope of the connection portion 32 may be tan8 °, tan10 ° or tan15 °, and the slope is specifically set according to actual needs, and this embodiment is not limited to this. It should be added that, in order to prevent the relative slipping problem caused by the small friction between the handle 3 and the hand of the user when the user holds the handle 3, the handle 3 of the present embodiment may be sleeved with a non-slip mat to increase the friction between the handle 3 and the hand of the user, so as to prevent the slipping problem. In addition, besides the anti-slip pad for increasing the friction force, anti-slip lines, anti-slip protrusions, and the like may be provided on the outer circumferential surface of the handle 3, and the anti-slip pad may also serve to increase the friction force.

Specifically, the handle 3 and the anti-slip pattern or the anti-slip bump may be formed integrally to save the processing process. The material of the non-slip mat can be rubber or silica gel and the like. The body 1 and the handle 3 may be made of plastic or alloy, or other materials may be selected according to actual needs, which is not specifically limited in this embodiment.
