Description

Technical Field

[0001] The invention belongs to the field of massagers and relates to a fascia gun, in particular to a contact transmission structure of a fascia gun and the fascia gun. Background Art

[0002] The fascia gun is a kind of massage equipment, which has a pistol-like structure, including a horizontal shell and a vertical handle, and a massage head is arranged at the front end of the shell. The massage head can vibrate back and forth, and the massage head is pressed against the muscle to vibrate the muscle, so as to achieve the effect of relaxing the muscles and activating blood circulation.

[0003] The existing fascia gun structure is shown in patent publication numbers CN110179646A and CN110882147A, which adopts the transmission structure of a traditional reciprocating saw. It includes a motor connected to an eccentric wheel, a rocker hinged to the eccentric wheel, a piston hinged to the front end of the rocker, the piston is restricted on the housing, and a massage head is provided to connect the piston. The above structure requires an increase in the housing space for swinging the rocker, and it is difficult to simplify the housing shape.

[0004] The existing fascia gun structure, such as patent publication number CN110680711A, adopts a flat transmission hole on the transmission rod, and an eccentric cylinder is provided on the rotating disk, and the cylinder is located in the transmission hole. The problem with this structure is that the flat width of the transmission hole needs to be larger than the rotation diameter of the cylinder. In order to avoid the transmission rod and the transmission hole being too wide, the distance between the cylinder and the axis of the rotating disk should also be reduced, resulting in a very small vibration amplitude of the fascia gun. If the vibration amplitude of the fascia gun is increased, then the transmission rod and the transmission hole need to be larger than the width of the rotating disk, which will also cause the width of the fascia gun housing to increase, and the purpose of streamlining cannot be achieved. Summary of the invention

[0005] The purpose of the present invention is to provide a contact transmission structure of a fascia gun and a fascia gun in view of the above-mentioned existing problems.

[0006] The objective of the present invention can be achieved through the following technical solutions: a contact transmission structure of a fascia gun, characterized in that it includes a motor arranged in a housing of the fascia gun, a rotating part connected to the motor, a transmission part restricted in the housing for reciprocating linear motion, and a massage head directly / indirectly connected to the transmission part, wherein the motor axis is parallel or colinear with the rotating axis of the rotating part, the motor axis is perpendicular to the movement direction of the transmission part, the contact part of the transmission part is in contact with the rotating edge of the rotating part, and when the rotating part rotates, at least two positions of the contact part have different linear spacings to the rotating axis of the rotating part.

[0013] Furthermore, one end of the transmission member is detachably connected to the massage head, or one end of the transmission member is connected to the adapter, and the adapter is detachably connected to the massage head.

[0014] Furthermore, a component for limiting the rotation of the transmission member is provided in the housing.

[0015] Furthermore, the component for limiting the rotation of the transmission member includes a protrusion arranged on the transmission member, and a long groove parallel to the movement direction of the transmission member is provided in the shell, and the protrusion is limited to slide in the long groove.

[0016] Furthermore, the component for limiting the rotation of the transmission member includes a circle of continuous protruding edges set on the rotating edge of the rotating member, and a bearing is provided at one end of the transmission member, the rolling part of the bearing contacts the rotating edge, and the side of the bearing contacts the edge.

[0032] Example 1

[0033] Figure 1 As shown, the fascia gun includes a shell 1, a handle 3 is provided under the shell 1, and a front hole 2 is provided at the front end of the shell 1 for inserting a massage head 4, and the massage head 4 can generally be detachably pulled out from the front hole 2.

[0034] The fascia gun is provided with a battery, which is located at the handle 3 and is provided with a charging port and a switch, as well as a circuit board for controlling the starting gear position (existing technology, which will not be described in detail).

[0035] Specifically, the housing 1 is placed horizontally, and the handle 3 is placed vertically. A motor 5 is arranged in a fixed position in the housing 1, and the axis of the motor 5 is in the vertical direction. The motor shaft 5-1 is connected to the rotating member 7, and the motor shaft 5-1 is connected to the eccentric position of the rotating member 7. Preferably, the motor shaft 5-1 and the rotating member 7 are connected through a coupling 6, and the axis of the motor 5 is parallel or colinear with the axis of the rotating member 7. The motor shaft 5-1 is directly connected to the rotating member 7 without passing through a gear box, which can reduce noise during transmission.

[0036] Preferably, Figure 2-Figure 3 As shown, the rotating member 7 can be an irregular shape, as long as the rotating edge of the rotating member 7 is a continuous arc, or an eccentric circle. More preferably, the rotating member 7 can be a cam.

[0037] A horizontally arranged transmission member 12 is provided in the housing 1. The transmission member 12 may be a rod-shaped structure or a structure with an arch in the middle and parallel ends. The transmission member 12 is restricted in the housing 1 and can only move back and forth linearly. Preferably, one end of the transmission member 12 is inserted into the front hole 2 of the housing 1, and there are reinforcing ribs inside the housing 1 to support the transmission member 12, so as to keep the transmission member 12 horizontal.

[0038] One end of the transmission member 12 contacts the edge of the rotating member 7 . Since the center of the rotating shaft of the rotating member 7 is eccentric, there is a maximum distance and a minimum distance from the axis of the rotating member 7 to the edge. The difference between the two distances is the movement distance of the transmission member 12 .

[0039] Preferably, one end of the transmission member 12 is provided with a rolling contact portion that contacts the rotating edge of the rotating member 7. Specifically, the contact portion includes a bearing 9, and the rolling portion of the bearing 9 contacts the rotating edge of the rotating member 7. More specifically, one end of the transmission member 12 is provided with a connecting shaft, and the connecting shaft is provided with a bearing 9.

[0040] Another form, Figure 6 As shown, the contact portion includes a ball 15 connection portion, in which the ball 15 is built, and the ball 15 contacts the rotating edge of the rotating member 7. More specifically, the ball 15 connection portion includes a C-shaped embedded groove, two-thirds of the ball 15 is located in the embedded groove, and the ball 15 has a point that contacts the rotating edge of the rotating member 7.

[0041] The front end of the transmission member 12 is connected to the massage head 4. Preferably, the front end of the transmission member 12 is provided with an axial hole, and the massage head 4 includes a software and a connecting rod, an O-ring is sleeved on the connecting rod, and the connecting rod is connected to the axial hole in an extrusion manner.

[0042] Alternatively, the front end of the transmission member 12 is connected to a transfer member, which is provided with an axial hole. The massage head 4 includes a software and a connecting rod, which is covered with an O-ring and is connected to the axial hole by extrusion.

[0043] When in use, the user presses the fascia massage head 4 on the massage part of the human body, and the massage head 4 is pushed forward by the stroke of the rotating member 7. When the massage head 4 returns to its original position, it relies on the pushing force when the external force squeezes the human body.

[0044] Figure 2 , Figure 5 As shown, when the contact part of the transmission member 12 is the bearing 9, it is necessary to prevent the transmission member 12 from rotating. Preferably, a circle of continuous protruding edges 8 is provided on the edge of the rotating member 7, the rolling part of the bearing 9 contacts the edge of the rotating member 7 and the side of the bearing 9 abuts against the protruding edge 8 of the rotating member 7, so that the rotation of the transmission member 12 can be restricted.

[0045] For example, Figure 4 As shown, a protrusion 10 is provided on the transmission member 12, and a long groove 14 parallel to the movement direction of the transmission member 12 is provided in the housing 1, and the protrusion 10 is limited to slide in the long groove 14, and the protrusion 10 is equal in width to the long groove 14. At the same time, when the transmission member 12 moves forward, the protrusion 10 hits the anti-detachment component 13 in front of the housing 1 to prevent the transmission member 12 from detaching.

[0046] When the contact part of the transmission member 12 is the rolling ball 15, the transmission member 12 can rotate. The transmission member 12 can also be restricted from rotating. Specifically, a protrusion 10 is provided on the transmission member 12, and a long groove 14 parallel to the movement direction of the transmission member 12 is provided in the housing 1. The protrusion 10 is limited to slide in the long groove 14, and the protrusion 10 is equal in width to the long groove 14. At the same time, when the transmission member 12 moves forward, the protrusion 10 hits the anti-detachment component 13 in front of the housing 1 to prevent the transmission member 12 from detaching.

[0047] Preferably, a reset and shock-absorbing structure can be provided, for example, a spring 11 is provided in the housing 1, a pushing portion is provided on the transmission member 12, one end of the spring 11 is connected to the front of the housing 1, and the other end is connected to the pushing portion. Preferably, the pushing portion and the protrusion 10 are of the same structure, and more preferably, the spring 11 is sleeved on the transmission member 12, and the pushing portions have two symmetrical ones. The spring 11 allows the end of the transmission member 12 to always be in contact with the edge of the rotating member 7.

[0048] In the above structure, the transmission member 12 is always horizontal and reciprocates in one direction. The contact point of the transmission member 12 is at the edge of the rotating member 7, so when the size of the rotating member 7 is limited to adapt to the width of the housing 1, the reciprocating stroke of the transmission member 12 can be maximized.

[0051] The fascia gun is provided with a battery, which is located at the handle 3 and is provided with a charging port and a switch, as well as a circuit board for controlling the starting gear position (existing technology, which will not be described in detail).

[0052] Specifically, the housing 1 is placed horizontally, and the handle 3 is placed vertically. A motor 5 is provided in a fixed position in the housing 1. Figure 7 As shown, the axis of the motor 5 is in the horizontal direction. The motor shaft 5-1 is connected to a transmission gear set that changes direction, and the transmission gear set is limited in the tooth groove of the housing 1. It includes bevel gear 1 17 and bevel gear 2 16. Bevel gear 1 17 is connected to the motor shaft 5-1, and bevel gear 2 16 is connected to the shaft of the rotating member 7. The shaft of the rotating member 7 is in an eccentric position during rotation. The axis of the motor 5 is perpendicular to the axis of the rotating member 7.
