DETAILED DESCRIPTION

[0024] In order to make the technical means, creation features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0025] Embodiment: as shown in Figures 1-6 The utility model discloses a double-end fascia gun, including shell 5 and its inside electric control driving assembly 4, and electric control driving assembly 4 top transmission is connected with linkage assembly 3, and linkage assembly 3 is connected with massage head 1 outside transmission of shell 5;Linkage assembly 3 includes eccentric wheel 31 and the double-end connecting rod 32 of sleeve joint in the outside of eccentric wheel 31, and it is driven double-end connecting rod 32 by eccentric wheel 31 of the single power source provided by electric control driving assembly 4 to realize the vibration of massage head 1;Double-end connecting rod 32, the same side is provided with the joint parallel to each other and outside shell 5, is used for detachably connecting massage head 1, compared with the complicated transmission structure in the prior art, the transmission structure of the application is less and more compact, also saves production cost, reduces the difficulty of maintenance.

[0026] In this embodiment, the housing 5 is curved (similar to the shape of a ruyi), and is composed of a front upper housing 51, a front lower housing 52, and a handle 53. The massage head 1 faces the handle 53. The electronically controlled drive component 4 is located inside the front lower housing 52 and the handle 53. The linkage component 3 is set in the space formed by the front upper housing 51 and the front lower housing 52. This shape is ergonomic and conforms to people's grip habits, making it convenient to massage the back.

[0027] In this embodiment, as Figures 1-3 As shown, a piston assembly 2 is provided between the massage head 1 and the connector. The piston assembly 2 includes a silicone piston 21 sleeved on the outside of the connector. Part of the silicone piston 21 is engaged between the front upper shell 51 and the front lower shell 52, and part of it is exposed outside the shell 5. A washer ring 22 is also provided inside the silicone piston 21 to support and restrict the silicone piston 21. A piston engaging ring 23 is provided on the outside of the silicone piston 21 exposed outside the shell 5. The piston engaging ring 23 is engaged on one side of the front upper shell 51 and the front lower shell 52, which can both help restrict the front upper shell 51 and help fix the silicone piston 21. Compared with the prior art, this application uses the silicone piston 21 to control the left and right swing amplitude of the vibration linkage, which overcomes the defects of different frequency vibration and inability to output vibration vertically, so that the vibration of the linkage assembly 3 can be better transmitted to the massage head 1 through the double-headed linkage 32.

[0028] In this embodiment, as Figure 4 As shown, the linkage assembly 3 also includes a bearing 33 disposed between the eccentric wheel 31 and the double-ended connecting rod 32, which is used to reduce the frictional resistance between the two and improve the service life of the device.

[0029] In this embodiment, as Figures 4-5 As shown, the electronically controlled drive assembly 4 includes a drive motor 41, a battery 45, and a control board 43. The motor is fixed inside the front lower shell 52 by a motor mounting bracket 42. The output shaft of the drive motor 41 is fixedly connected to the eccentric wheel 31. The battery 45 is fixed inside the handle 53. The bottom of the handle 53 is provided with a tail cover 54 with a charging plug 44 for charging the battery 45. The control board 43 is electrically connected to one side of the battery 45. The control board 43 is electrically connected to the drive motor 41 and the charging plug 44. A button 46 is provided on one side of the handle 53. The button 46 is adapted to the button position on the control board 43. By pressing the button 46, the opening and closing of the double-headed fascia gun and the function switching can be controlled. In use, this application drives the two massage heads 1 to vibrate through the same drive motor 41. Compared with the dual independent motor drive of the prior art, it saves production costs, reduces the frequency of maintenance caused by the increase in the number of motors, reduces the cost of motor maintenance for users, and improves market competitiveness.

[0030] In the embodiment, as shown in Figure 5 The handle is provided with anti-skid decorative strips 531 on both sides to increase the gripping friction.

[0031] In the embodiment, the massage head 1 can be detached and replaced with a different shape. Figure 6 As shown in the figure, the contact surface shape of the massage head 1 is round 11, forked 12 or ring-shaped 13 from left to right, and any combination of the above two shapes can be made according to the user's needs, and different shapes can be replaced according to the user's needs.

[0032] In use, the button 46 is pressed to touch the keys on the control board 43, the control board 43 controls the driving motor 41 to start, and the power is transmitted to the eccentric wheel 31, the eccentric wheel 31 does eccentric motion through the bearing 33 to drive the double-head connecting rod 32 to vibrate, and then the left and right swing amplitude of the silicone piston 21 is controlled to ensure the vertical output, and finally the power is transmitted to the massage head 1 to massage the user, the power transmission process is simple and direct, avoiding the use of traditional double-motor and complex transmission structure scheme (the existing double-head fascia gun needs a rotating connection to transmit power), greatly reducing the production cost and maintenance difficulty and frequency.

[0033] The basic principle, main features and advantages of the utility model are shown and described above. It should be understood by those skilled in the art that the utility model is not limited by the above embodiments, and the above embodiments and the description in the specification are only to illustrate the principle of the utility model, and various changes and improvements can be made to the utility model without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model. The scope of protection of the utility model is defined by the appended claims and their equivalents.
