Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application; the technical features designed in the different embodiments of the application described below can be combined with each other as long as they do not conflict with each other; all other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

In the description of the present application, it should be noted that all terms used in the present application (including technical terms and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs and are not to be construed as limiting the present application; it will be further understood that terms used herein should be interpreted as having a meaning that is consistent with their meaning in the context of this specification and the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

As shown in fig. 1 to 5, the present application provides a fascia gun including a housing 200, a massage head 100, a driving motor 300, a driving shaft sleeve 500, a limiting guide groove 410, and a link 700.

A motor fixing seat 400 is arranged in the shell 200, and an opening is arranged at one end of the shell 200. A guide bar 210 is provided at one side of the massage head 100, and the guide bar 210 is reciprocally movably provided in the opening. Specifically, the housing 200 may be a single-opening hollow cylinder structure, and other components of the fascia gun are disposed inside the housing 200. During operation, the opening limits the movement direction of the guide bar 210, thereby ensuring that the massage track of the massage head 100 meets the requirements.

The driving motor 300 is fixed on the motor fixing base 400, and the driving motor 300 has an output shaft 310; the outdrive 500 includes a stopper 510 and a push rod 520 disposed on the outer sidewall, and the outdrive 500 is obliquely sleeved on the output shaft 310. Specifically, when the output shaft 310 rotates, the outdrive 500 does not rotate together with the output shaft 310, and the inclination angle corresponding to each point on the outdrive 500 changes periodically, i.e. the outdrive 500 swings with the rotation of the output shaft 310.

The limiting guide groove 410 is arranged on the driving motor 300 or the motor fixing seat 400, and the extending direction of the limiting guide groove 410 is parallel to the output shaft 310; one end of the connecting rod 700 is provided with a connecting hole 710, the connecting hole 710 is connected with the pushing rod 520, and the other end of the connecting rod 700 is connected with the guide rod 210 positioned in the opening; when the output shaft 310 rotates, the limit rod 510 slides reciprocally in the limit guide slot 410, so that the push rod 520 outside the driving sleeve 500 drives the massage head 100 to move reciprocally in the opening through the connecting rod 700. That is, the limit lever 510 limits the lateral displacement of each point on the outdrive 500, so that each point on the outdrive 500 is only periodically displaced in the direction of the output shaft 310, thereby causing the push lever 520 outside the outdrive 500 to displace in the direction of the output shaft 310 and finally transmitting the motion to the massage head 100 through the guide lever 210.

In actual operation, the drive motor 300 is started and the output shaft 310 rotates. The transmission shaft sleeve 500 generates periodic change on the inclined surface under the action of the output shaft 310, so that the limit rod 510 slides reciprocally in the limit guide groove 410, and further, the push rod 520 at the outer side of the transmission shaft sleeve 500 drives the massage head 100 to reciprocate in the opening through the connecting rod 700, thereby realizing a massage mode of high-frequency impact.

Preferably, as shown in fig. 1 and 2, the end of the push rod 520 is provided with a transmission block 530, and part of the outer surface of the transmission block 530 is in a spherical or circular ring structure, and the outer surface of the transmission block 530 corresponding to the connection hole 710 of the connecting rod 700 is provided, so that when the push rod 520 swings, the connection hole 710 is sleeved on the outer surface of the transmission block 530. Specifically, the transmission block 530 can effectively reduce the friction between the push rod 520 and the link 700, reduce noise, and simultaneously ensure that the transmission rod is not affected by transverse torsion.

In an embodiment, as shown in fig. 2 to 5, the driving device further includes a driving block 600, where the driving block 600 is fixed on the output shaft 310, and the driving block 600 is provided with an abutment surface that abuts against the driving shaft sleeve 500, and the abutment surface is disposed obliquely with respect to the output shaft 310, so that when the output shaft 310 rotates, the abutment surface pushes the driving shaft sleeve 500 to swing. Specifically, the abutment surface of the pushing block 600 is an inclined surface, and the inclined surface rotates together with the output shaft 310, and the rotating inclined surface pushes the driving shaft sleeve 500, so that the periodical inclination angle change is generated. Meanwhile, the structure of the pushing block 600 is adopted, so that stable transmission of torsion can be ensured, the structure is simple, the stability is strong, various problems such as blocking and derailment cannot occur, the swing transition of the driving shaft sleeve 500 is stable, and the noise is low.

Preferably, as shown in FIG. 2, the axis of the pusher block 600 is located on a different line than the output shaft 310. That is, the pushing block 600 is eccentrically arranged, so that the axis of the pushing block is vertical to the inclined plane, thereby ensuring smooth transmission between the driving shaft sleeve 500 and the pushing block 600.

In one embodiment, as shown in FIG. 2, the outdrive 500 is sleeved on the output shaft 310 through a first bearing 540.

Preferably, as shown in FIG. 2, the drive block 530 is a self-aligning bearing.

Further, as shown in fig. 3 to 4, the diameter of the end of the housing 200 near the opening is gradually reduced. That is, one end of the housing 200 close to the opening is contracted toward the central axis, and the whole housing is in an inverted funnel shape, so that the arrangement can save the occupied space while improving the aesthetic feeling.

Preferably, the linkage 700 is located in the same plane as the output shaft 310 as a whole. That is, the overall direction of the link 700 is in the extending direction of the output shaft 310, so that the overall structure is linear.

Preferably, the end of the link 700 connected to the guide bar 210 is on the same axis as the output shaft 310 of the driving motor 300. The coaxial line is arranged to enable the integral structure of the fascia gun to be compact, simultaneously enable transmission of torsion between structures to be smoother, and effectively prolong service life.

Preferably, as shown in fig. 2, the link 700 is connected to the guide bar 210 through a second bearing 720.

Specifically, the first bearing 540 and the second bearing 720 may be roller bearings, and the arrangement of the first bearing 540 and the second bearing 720 can reduce friction between adjacent structures during transmission, reduce noise and influence of transverse torsion, prevent structural deformation, and effectively improve service life.
