[0048] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0049] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In order to make the technical solutions and advantages of this application clearer, the fascia gun, etc. will be described in detail in conjunction with the drawings.

[0050] The fascia gun, also known as the deep myofascial impactor, uses a motor to drive the massage head to perform high-frequency impacts on the muscles to squeeze, stimulate and comb the knots between the muscles, relax the tense and stiff muscles, and thus reduce the pain and discomfort caused by exercise.

[0051] Currently, fascia massage guns usually include a horizontal barrel and a longitudinal barrel, forming an L-shaped or T-shaped structure. One side of the barrel serves as a handle, and the other side of the barrel is provided with a massage head. Such fascia massage guns are generally large in size and not easy to carry.

[0052] In this regard, the present application provides a fascia gun, such as Figure 1 and Figure 2 As shown, the fascia gun includes a massage head assembly 1 and a main body assembly 2; the massage head assembly 1 is connected to the main body assembly 2, and the axial direction of the massage head assembly 1 coincides with the axial direction of the main body assembly 2, and the main body assembly 2 is used to drive the massage head assembly 1 to reciprocate along its axial direction; the massage head assembly 1 includes a massage head cover 11, a first shell 12 and a heating component 13, the massage head cover 11 is provided on one end of the first shell 12 away from the main body assembly 2, and is connected to the first shell 12, the massage head cover 11 is a heat-conducting component; the heating component 13 is located inside the first shell 12, and is used to heat the massage head cover 11.

[0053] In some embodiments, the axial direction of the massage head assembly 1 can also be understood as the extension direction of the massage head assembly 1; the axial direction of the main unit assembly 2 can also be understood as the extension direction of the main unit assembly 2.

[0054] In the fascia gun provided in the embodiment of the present application, the axial direction of the massage head assembly 1 is the same as the axial direction of the main body assembly 2, so that the central axis of the massage head assembly 1 and the central axis of the main body assembly 2 can be located on the same straight line, so that the fascia gun as a whole has an "I"-shaped structure, is small in size, and is easy to carry.

[0055] The main assembly 2 can drive the massage head assembly to move back and forth to achieve the massage function, and the main assembly 2 also plays the role of a "handle" for the user to hold. The overall structure of the fascia gun is relatively compact, which is convenient for the user to carry at any time, thereby improving the convenience and portability of the fascia gun.

[0056] Furthermore, in order to reduce the size of fascia guns in related art and make them easier for users to carry, some functional components (such as the heating device) are generally removed to save internal space and thus reduce the overall size of the fascia gun. Although this configuration can meet the user's convenience needs, it also sacrifices some functions and is difficult to meet the diverse needs of users.

[0057] In the fascia gun provided in the embodiment of the present application, a heating component 13 is also provided inside the massage head assembly 1, which can heat the massage head while realizing the massage function, which can not only increase blood circulation and promote blood vessel dilation, but also improve the blood supply and oxygen supply to the muscles, and help relieve muscle tension and pain.

[0058] In some embodiments, the opening on one side of the first housing 12 where the massage head cover 11 is provided is a bell-shaped opening, and a portion of the first housing 12 extends outward, thereby increasing the accommodation space inside the bell-shaped opening. The heating assembly 13 is located inside the bell-shaped opening and is connected to the massage head cover 11 to heat the massage head cover 11. The fascia massage gun provided in the embodiment of the present application retains the heating function while not increasing the size of the remaining parts of the fascia massage gun except for the massage head cover 11, thereby satisfying both versatility and convenience of the fascia massage gun.

[0059] For example, Figure 3 As shown, the first shell 12 includes a first section 122, a second section 123 and a third section 124 connected in sequence; the first section 122 includes a large head end 1221 and a small head end 1222, the massage head cover 11 is connected to the large head end 1221, and the small head end 1222 is connected to the second section 123; wherein, the cross-sections of the small head end 1222, the second section 123 and the third section 124 perpendicular to the axial direction of the massage head assembly 1 are all circular, and the diameters of the small head end 1222, the second section 123 and the third section 124 decrease in sequence.

[0060] The end of the first shell 12 provided with the massage head cover 11 is set as the large head end 1221, while the size of the remaining parts is reduced. This not only increases the internal space of the first shell 12 and retains the heating function of the heating component 13, but also makes the shapes of the two ends of the first shell 12 along the extension direction inconsistent, thereby setting the first shell 12 to an asymmetric shape to form a fool-proof structure, which can avoid assembly errors and thus improve assembly efficiency.

[0061] In addition, if Figure 2 As shown, the heating component 13 provided in the embodiment of the present application can be a disc-shaped heating component 13, which is attached to the side of the massage head cover 11 close to the main assembly 2. The disc-shaped heating component 13 is similar in shape to the massage head cover 11, can improve the heating efficiency, and occupies less space itself.

[0062] Moreover, due to the larger size of the large head end 1221, the size of the massage head cover 11 will also increase accordingly. Compared with the spherical or hemispherical massage heads in the related art, the large-sized massage head cover 11 will also increase the contact area with the skin and muscles, which can give the user a better massage experience.

[0063] Optionally, the massage head cover 11 is a flat head or an arc-shaped head, and those skilled in the art can select and adjust the type of the massage head cover 11 according to actual needs.

[0064] Among them, when the massage head cover 11 uses a flat head, the flat head is suitable for massaging all parts of the body, including shoulders, back, buttocks, legs, etc., and can meet the massage needs of different parts of the body; and the contact surface between the flat head and the skin is relatively flat, which can provide a uniform and stable massage effect, and will not concentrate on a certain point, causing discomfort.

[0065] Optionally, the massage head cover 11 is a ceramic component or a metal component.

[0066] Among them, the metal massage head cover 11 usually has high durability and can withstand long-term use without being easily worn or deformed; and metal has good thermal conductivity and can quickly conduct the heat generated by the heating component 13 to the surface of the massage head cover 11, thereby improving heating efficiency.

[0067] The surface of the ceramic massage head cover 11 is generally very smooth, which can provide a soft and comfortable massage experience and reduce skin friction and irritation; in addition, ceramics have good corrosion resistance and rust resistance, and are easy for users to clean; and the ceramic massage head cover 11 is lighter than the metal massage head cover 11, which can further reduce the overall weight of the fascia gun and improve convenience and portability.

[0068] In one implementation of the embodiment of the present application, Figure 2As shown, the heating assembly 13 may include a heating element 131 and a heat conductor 132; the heating element 131 is configured to generate heat when powered on; the heat conductor 132 is attached to the side of the heating element 131 close to the massage head cover 11, and is connected to or against the massage head cover 11 to transfer the heat generated by the heating element 131 to the massage head cover 11.

[0069] If the heat-generating heating element 131 is directly connected to the massage head cover 11, uneven heat transfer and damage to the massage head may occur. Therefore, in the fascia massage gun provided in the embodiment of the present application, a heat conductor 132 can be further provided between the heating element 131 and the massage head cover 11 to separate the heating element 131 from the massage head cover 11. The heat conductor 132 itself has heat conductivity, which not only ensures the heating function of the fascia massage gun but also prevents damage and uneven heat transfer.

[0070] Optionally, the heat conducting member 132 is heat conducting silica gel.

[0071] The fascia gun provided in the embodiment of the present application uses thermally conductive silicone as the heat conductor 132, which can effectively conduct the heat generated by the heating plate to the surface of the massage head, achieving a more uniform heating effect and thus avoiding local high temperature, providing the best massage experience; and the thermally conductive silicone has good thermal conductivity, which can improve the heating efficiency, shorten the preheating time, and allow users to enjoy the comfortable effect of hot compress massage more quickly; in addition, the thermally conductive silicone has good stability and durability, and can withstand long-term high-temperature operation without deformation or damage, which ensures the long-term performance and reliability of the heating plate and the massage head, and extends the service life of the massager.

[0072] In some embodiments, the heating element 131 can be a heating sheet that can convert electrical energy into thermal energy, thereby providing heat for the massage head cover 11; and the heating element 131 is sheet-shaped, similar in shape to the massage head cover 11, and can transfer heat more evenly, and the space it occupies is small, thereby avoiding affecting the overall volume of the fascia gun.

[0073] In one implementation of the embodiment of the present application, Figure 4As shown, the heating component 13 may also include a heating mainboard 133, a conductive connector 134 and a first wire 135. The interior of the first shell 12 has a chamber 121 and a first mounting groove 125, wherein the first mounting groove 125 is opened at the end of the first shell 12 away from the massage head cover 11. A through hole 1251 is opened on the bottom wall of the first mounting groove 125, and the protruding end of the conductive connector 134 passes through the heating mainboard 133 and the through hole 1251 in sequence and extends into the chamber 121, and the conductive connector 134 is exposed at the bottom wall so as to be suitable for electrical connection with the power supply component provided in the main assembly 2; the first wire 135 is located in the chamber 121 and is connected to the protruding end of the conductive connector 134, and the end of the first wire 135 away from the conductive connector 134 is connected to the heating element 131.

[0074] In the prior art, the massage head and the main unit are typically electrically connected via a copper sheet. During use, the massage head assembly 1 moves up and down at a high frequency, causing the connector (i.e., the contacts of the massage head assembly 1) to slightly rub and collide with the corresponding contacts in the main unit. The copper sheet is generally thin, and friction and other factors can damage it during use, leading to disconnection.

[0075] Therefore, in the fascia massage gun provided in this embodiment of the present application, one end of the conductive connector 134 extends through the heating mainboard 133 into the chamber 121 inside the first housing 12, where it is connected to the first wire 135. The other end is located on the side of the heating mainboard 133 facing the main body assembly 2 and is exposed from the first housing 12, serving as a contact in the massage head assembly 1 and contacting a corresponding contact in the main body assembly 2 to achieve an electrical connection. Compared to using copper sheets as contacts, the conductive connector 134 provided in this embodiment of the present application is longer and less susceptible to wear and damage.

[0076] In some embodiments, the conductive connector 134 may include a main body 1341 and an extension section 1342 connected to each other; the main body 1341 is located on the side of the heating main board 133 away from the first wire 135, and is exposed to the bottom wall of the first mounting groove 125; the extension section 1342 extends along the axial direction of the main body 1341, and the cross-section of the extension section 1342 perpendicular to the axial direction is arc-shaped, and a portion of the first wire 135 is located in the extension section 1342 and is connected to the extension section 1342.

[0077] like Figure 5 As shown, since an extension section 1342 is provided at one end of the main body 1341, during welding, a portion of the first wire 135 can be placed in the extension section 1342, and then the first wire 135 can be welded through the open portion on the extension section 1342, which makes welding more convenient.

[0078] Exemplarily, the angle of the arc is 180°, and those skilled in the art can select and adjust the angle according to actual needs.

[0079] Optionally, the conductive connector 134 is a metal connector, and those skilled in the art can select and adjust the type of the conductive connector 134 according to actual needs.

[0080] Exemplarily, the conductive connecting member 134 is a conductive copper pillar.

[0081] In one implementation of the embodiment of the present application, the main unit assembly 2 may include a second shell 21 and a connector 22; a second mounting groove 211 is provided at one end of the second shell 21 close to the massage head assembly 1, and at least one through-hole 2211 is provided on the bottom wall of the second mounting groove 211; the end of the first shell 12 away from the massage head cover 11 extends into the second mounting groove 211 and abuts against the bottom wall of the second mounting groove 211; the connector 22 is located inside the second shell 21 and is electrically connected to the conductive connector 134 through at least one through-hole 2211.

[0082] like Figure 6 As shown, one end of the massage head assembly 1 extends into the second mounting groove 211. The connector 22 inside the second housing 21 passes through the opening 2211 in the second mounting groove 211 and connects to the massage head assembly 1. The connector 22 is connected to the guide block 24, which is in turn connected to the drive arm 25 of the drive motor (not shown) inside the second housing 21. Driven by the drive arm 25, the guide block 24 drives the massage head assembly 1 to reciprocate along the extension direction of the second mounting groove 211 to achieve the massage function. The connector 22 is used to establish an electrical connection between the conductive connector 134 and the main assembly 2.

[0083] Optionally, the connector 22 is an anti-vibration connector 22 to avoid risks such as poor contact and instantaneous power failure when the massage head assembly 1 is working.

[0084] In some embodiments, as Figure 6 As shown, a side of the guide block 24 close to the massage head assembly 1 is provided with an avoidance groove 241, and a second wire 242 is provided in the avoidance groove 241, and the second wire 242 is connected to the power supply inside the second shell 21; the connector 22 has a plurality of contacts inside, and the two ends of the contacts are respectively connected to the second wire 242 and the conductive connector 134, for realizing the electrical connection between the host assembly 2 and the massage head assembly 1; wherein, the contacts can be telescopically moved along the extension direction of the connector 22, and by providing the avoidance groove 241, the contacts will not be damaged by the squeezing force of the guide block 24 and the conductive connector 134 when telescopically moving.

[0085] In one implementation of the embodiment of the present application, the heating assembly 13 includes a plurality of conductive connectors 134 , and the outer contour of the bottom wall of the first mounting groove 125 is a non-centrosymmetrical figure.

[0086] For example, the outer contour of the bottom wall of the first mounting groove 125 includes a trapezoidal section 126, and the width of the trapezoidal section 126 is linearly narrowed along the length direction of the bottom wall, wherein the length direction is perpendicular to the axial direction of the massage head assembly 1 and perpendicular to the width direction of the trapezoidal section 126. Figure 7 As shown, the outer contour of the portion includes a large head section, a trapezoidal section 126 and a small head section connected in sequence, and a plurality of conductive connecting members 134 are sequentially arranged at intervals along the height direction of the trapezoidal section 126 .

[0087] It should be noted that the plurality of conductive connectors 134 include positive and negative electrodes, and the positive and negative electrodes are generally located at opposite ends. Therefore, the positions of the positive and negative electrodes of the conductive connectors 134 can be easily distinguished based on the direction of the tapering or widening of the trapezoidal segments 126. This prevents assembly errors from occurring during electrical connection with the connector 22 of the main assembly 2, which could result in a short circuit between the massage head assembly 1 and the main assembly 2.

[0088] In some embodiments, the bottom wall of the first mounting groove 125 can be made of a PVC board, that is, the end of the first mounting groove 125 away from the massage head cover 11 can be blocked by a PVC board. The PVC board has fireproof properties to improve the safety of the fascia gun.

[0089] Furthermore, the surface of the connector 22 facing the massage head assembly 1 may be provided with a third mounting groove 221, and the third section 124 of the first housing 12 may extend into the third mounting groove 221. This means that the portion of the first housing 12 provided with the second mounting groove 211 is also located within the third mounting groove 221. In some embodiments, the shape of the third mounting groove 221 may match the shape of the portion of the first housing 12 provided with the first mounting groove 125, thereby preventing the massage head assembly 1 from being assembled with the main unit assembly 2 in reverse polarity, thereby improving safety.

[0090] In some embodiments, the main assembly 2 may further include a connecting sleeve 23, such as Figure 6 As shown, the connecting sleeve 23 is sleeved on the outer side wall of the part of the first shell 12 that extends into the second mounting groove 211. Since the massage head assembly 1 needs to reciprocate along the extension direction of the second mounting groove 211 during operation, the connecting sleeve 23 is sleeved on the outside of the first shell 12. The connecting sleeve 23 can prevent the first shell 12 from directly rubbing and colliding with the second mounting groove 211 during the reciprocating movement, thereby improving the service life of the fascia gun.

[0091] As shown in the figure, the end face of the connecting sleeve 23 away from the guide block 24 abuts against the small head end 1222 in the first shell 12. When the massage head assembly 1 moves back and forth, the end of the connecting sleeve 23 close to the guide block 24 is pushed by the guide block 24, which in turn causes squeezing and friction on the small head end 1222.

[0092] Therefore, in some embodiments, Figure 6 As shown, the massage head assembly 1 can also include a vibration damper 14, which is a deformable elastic component; the second section 123 is provided with an assembly groove 1231, and the vibration damper 14 is partially sleeved in the assembly groove 1231 and abuts against the side wall of the small head end 1222 close to the second section 123.

[0093] The two ends of the connecting sleeve 23 are connected to the guide block 24 and the small end 1222, respectively. When the massage head assembly 1 is in operation, the vibration frequency of the massage head assembly 1 is relatively high, and the connecting sleeve 23 may collide with and rub against the small end 1222. Therefore, a vibration damper 14 can be provided. The vibration damper 14 is not only elastic but also creates an interference fit between the connecting sleeve 23 and the small end 1222, thereby preventing vibration and friction between the connecting sleeve 23 and the small end 1222, thereby extending the service life of the fascia massage gun.

[0094] In some embodiments, the assembly groove 1231 is an annular groove, and the width of the annular groove may be smaller than the length of the portion of the vibration damping member 14 located in the assembly groove 1231 .

[0095] Since the vibration damper 14 is a deformable elastic component, after a part of the vibration damper 14 is placed in the assembly groove 1231, it can be stuck in the assembly groove 1231 under the action of its own elastic force and will not fall off easily, which is more convenient when assembled with other components.

[0096] When the vibration damper 14 is squeezed by the connecting sleeve 23 and the small end 1222, it will undergo a certain degree of elastic deformation, which will cause relative movement between the connecting sleeve 23 and the first housing 12. In other words, the connecting sleeve 23 and the portion of the vibration damper 14 that is mounted on the first housing 12 will also move relative to each other. If the connecting sleeve 23 fits tightly against this portion, the friction force may affect the smooth deformation of the vibration damper 14, thereby affecting the vibration damping effect of the vibration damper 14.

[0097] In some embodiments of the present application, Figure 8 As shown, an annular protrusion 141 is formed on one side of the vibration damping member 14 away from the small head end 1222 , and the annular protrusion 141 protrudes in a direction away from the central axis of the vibration damping member 14 .

[0098] The annular protrusion 141 abuts against the inner wall of the connecting sleeve 23, so that there is a certain gap between the portion of the connecting sleeve 23 that is sleeved on the first shell 12 and the connecting sleeve 23. When the vibration damper 14 is deformed, only friction is generated between the annular protrusion 141 and the connecting sleeve 23, which reduces the contact area. That is, the friction between the connecting sleeve 23 and the vibration damper 14 is reduced, which can improve the vibration damping effect of the vibration damper 14.

[0099] According to the above embodiments, since the massage head assembly 1 needs to reciprocate along the extension direction of the second mounting groove 211 during operation, a connecting sleeve 23 is provided on the exterior of the first housing 12, and the connecting sleeve 23 needs to move with the massage head assembly 1. To ensure that the connecting sleeve 23 does not slip or fall off during movement, in some embodiments, a first annular groove 1232 may be defined on the outer wall of the second section 123, and the massage head assembly 1 may further include a first anti-slip member 15, which is located within the first annular groove 1232; and / or, in other embodiments, a second annular groove 1241 is defined on the outer wall of the third section 124, and the massage head assembly 1 further includes a second anti-slip member 16, which is located within the second annular groove 1241.

[0100] like Figure 6 As shown, by arranging a first anti-slip member 15 between the first shell 12 and the connecting sleeve 23, the first anti-slip member 15 elastically abuts against the groove wall of the first annular groove 1232 and the inner wall of the connecting sleeve 23 respectively, which can increase the friction between the connecting sleeve 23 and the first shell 12, thereby preventing the connecting sleeve 23 from sliding or falling off.

[0101] In addition, if Figure 6 As shown, a portion of the connector 22 extends into the connecting sleeve 23 and wraps around the outside of the third section 124. To prevent relative sliding between the connector 22 and the third section 124, the fascia gun provided in the embodiment of the present application may further be provided with a second anti-slip member 16. The second anti-slip member 16 elastically abuts against the groove wall of the second annular groove 1241 and the connector 22, respectively, thereby increasing the friction between the connector 22 and the third section 124, thereby preventing the connector 22 from sliding or falling off.

[0102] Exemplarily, the first anti-slip member 15 is an elastic O-ring; and / or the second anti-slip member 16 is an elastic O-ring.

[0103] In some embodiments, the size of the first anti-slip part 15 can be slightly larger than the groove width of the first annular groove 1232, and the size of the second anti-slip part 16 can be slightly larger than the groove width of the second annular groove 1241, so that the first anti-slip part 15 and the second anti-slip part 16 can be stuck in the first annular groove 1232 and the second annular groove 1241 by their own elastic force, and will not easily fall off under the action of external force, which is convenient for assembly with other components.

[0104] It should be noted that the assembly process of the fascia gun provided in the embodiment of the present application is as follows: the shock absorber 14 is put on the first shell 12 and stuck in the assembly groove 1231, the first anti-slip part 15 and the second anti-slip part 16 are respectively installed in the first annular groove 1232 and the second annular groove 1241, and then the connecting sleeve 23 is placed in the second installation groove 211 and put on the outside of the connector 22, and finally the massage head assembly 1 is inserted into the connecting sleeve 23, and after it abuts against the connector 22, the assembly is completed.
