Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a shiftable massager. Background Art

[0002] Massagers can help users relieve stress and fatigue, and proper use is beneficial to physical and mental health. Massagers use an internal vibration motor to generate vibrations to massage the body. Due to differences in physical fitness, the massager's amplitude and frequency, as well as the gear position, need to be adjusted to meet user needs. Specifically, the output voltage is controlled by the PCB board to adjust the output power of the vibration motor, achieving the gear shifting function.

[0003] However, the internal space of the massager is limited, and a high-power vibration motor cannot be installed therein. This also results in the massage intensity of the existing massager not changing significantly after switching gears, reducing the user's adaptation experience. Utility Model Content

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art and to provide a shiftable massager, so that the amplitude can be significantly different after the gear is switched, giving the user a different using experience.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] A shiftable massager comprising: an outer cover, a silicone body, a controller, and a vibration module;

[0007] The outer skin is wrapped around the outside of the silica gel body;

[0008] The silicone body is provided with a gripping portion and a massage portion, the controller is located in the gripping portion, the vibration module is located in the massage portion, and the controller and the vibration module are electrically connected via a wire;

[0009] The vibration module includes a vibration motor, an eccentric rotor, a housing, and a magnetic latch. The eccentric rotor and the housing are both arranged on the output shaft of the vibration motor, and the housing is rotatably connected to the output shaft of the vibration motor. The vibration motor is used to drive the eccentric rotor to rotate. The eccentric rotor is provided with a receiving hole, and the magnetic latch is slidably arranged in the receiving hole.

[0010] A frame is provided on the side of the outer sleeve close to the eccentric rotor, the magnetic latch is arranged toward the frame, and a blocking portion matching the magnetic latch is provided on the frame.

[0011] In one embodiment, the controller is equipped with a battery, a control board and a charging base.

[0012] In one embodiment, the control panel is provided with a button, and the grip portion is provided with a protrusion matching the button.

[0013] In one embodiment, the silicone body is thick at both ends and narrow in the middle.

[0014] In one embodiment, the vibration module further includes a shell and an end cover. The shell is a cylindrical structure with an opening on one side. The vibration motor, the eccentric rotor, the outer sleeve and the magnetic latch are all located in the shell. The end cover is used to close the opening of the shell.

[0015] In one embodiment, a wrench position is provided on the outer wall of the vibration motor, and a holding rod matching the wrench position is provided on the end cover.

[0016] In one embodiment, a bushing is provided between the outer sleeve and the output shaft of the vibration motor.

[0017] In one embodiment, an eccentric portion is provided on the outer sleeve.

[0018] In one embodiment, a blocking ring is provided on the outlet side of the receiving hole.

[0019] The advantage of the above-mentioned shiftable massager is that after switching gears, the speed of the eccentric rotor changes, which in turn drives the magnetic pin to lock the eccentric rotor and the outer shell, causing them to rotate synchronously, causing the eccentric mass to change, thereby increasing the amplitude after shifting gears, and increasing the difference in massage force of the massager before and after shifting gears, giving users a different usage experience.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended solely for the purpose of describing specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] See also Figure 1 The present invention provides a shiftable massager 10 , which includes: an outer shell 100 , a silicone body 200 , a controller 300 and a vibration module 400 .

[0033] The outer skin 100 is wrapped around the outside of the silicone body 200 .

[0034] The silicone body 200 includes a grip portion 210 and a massage portion 220. The controller 300 is located within the grip portion 210, and the vibration module 400 is located within the massage portion 220. The controller 300 and the vibration module 400 are electrically connected via wires. Preferably, the silicone body 200 is thicker at both ends and narrower in the middle, with the grip portion 210 and the massage portion 220 located at either end. The user grips the grip portion 210 and controls the vibration module 400 via the controller 300 to activate, deactivate, and shift gears.

[0035] See also Figure 2 and Figure 3 The vibration module 400 includes a vibration motor 410, an eccentric rotor 420, a housing 430, and a magnetic latch 440. The eccentric rotor 420 and the housing 430 are both disposed on the output shaft of the vibration motor 410, and the housing 430 is rotatably connected to the output shaft of the vibration motor 410. The vibration motor 410 is used to drive the eccentric rotor 420 to rotate. The eccentric rotor 420 is provided with a receiving hole 421, and the magnetic latch 440 is slidably disposed in the receiving hole 421.

[0036] See also Figure 2 and Figure 4 A frame 431 is provided on the side of the outer sleeve 430 close to the eccentric rotor 420 , the magnetic latch 440 is arranged toward the frame 431 , and a blocking portion 432 matching the magnetic latch 440 is provided on the frame 431 .

[0037] The distance operation principle of the vibration module 400 is as follows:

[0038] When the vibration motor 410 is just started, it is in a low-speed operation state. At this time, the magnetic latch 440 is adsorbed on the side of the receiving hole 421 close to the output shaft of the vibration motor 410 under its own magnetic force. The vibration motor 410 drives the eccentric rotor 420 to rotate alone. Figure 5 shown.

[0039] See also Figure 6 After the controller 300 switches the gear, the vibration motor 410 enters a high-speed operation state. As the eccentric rotor 420 rotates faster, the centrifugal force generated during the rotation becomes larger, causing the magnetic pin 440 to extend. When the extended part of the magnetic pin 440 contacts the blocking part 432, it will drive the outer cover 430 to rotate together with the eccentric rotor 420. Due to the addition of the outer cover 430, the eccentric mass becomes larger, which in turn causes the amplitude to increase. That is, after switching the gear, the vibration rate of the massager becomes faster and the vibration amplitude also increases.

[0040] When switching to low gear again, the speed of the vibration motor 410 decreases, and the centrifugal force generated by the rotation of the eccentric rotor 420 becomes smaller. When the centrifugal force is smaller than the magnetic attraction between the magnetic pin 440 and the output shaft of the vibration motor 410, the magnetic pin 440 retracts into the receiving hole 421. At this time, there is no connection between the outer sleeve 430 and the eccentric rotor 420, that is, the eccentric mass becomes smaller, and the amplitude also becomes smaller.

[0041] As can be seen from the above, after the gear is switched, the rotation speed of the eccentric rotor 420 changes, which in turn drives the magnetic latch 440 to lock the eccentric rotor 420 and the outer sleeve 430, so that they rotate synchronously, causing the eccentric mass to change, thereby increasing the amplitude after the gear shift, and increasing the difference in massage intensity of the massager before and after the gear shift, which can give users a different usage experience.

[0042] See also Figure 1 In one embodiment, the controller 300 includes a battery 310, a control panel 320, and a charging station 330. The control panel 320 includes a button 321, and the grip 210 includes a protrusion 211 that matches the button 321. The protrusion 211 allows the user to clearly identify the location of the button 321, making it easier for the user to operate the controller 300.

[0043] See also Figure 2 In one embodiment, the vibration module 400 further includes a housing 450 and an end cap 460. The housing 450 is a cylindrical structure with an opening on one side. The vibration motor 410, eccentric rotor 420, outer sleeve 430, and magnetic latch 440 are all located within the housing 450. The end cap 460 is used to seal the opening of the housing 450. A wrench position 411 is provided on the outer wall of the vibration motor 410, and a lever 461 is provided on the end cap 460 to mate with the wrench position 411. The lever 461 tightly fits the wrench position 411, securing the vibration motor 410 to the housing 450 and preventing the vibration motor 410 from shaking and weakening the vibration effect.

[0044] See also Figure 2 and Figure 3 Preferably, a bushing 470 is provided between the outer sleeve 430 and the output shaft of the vibration motor 410. When the output shaft of the vibration motor 410 rotates relative to the outer sleeve 430, the friction is reduced to prevent the output shaft of the vibration motor 410 from accidentally driving the outer sleeve 430 to rotate.

[0045] See also Figure 3 and Figure 4 Preferably, an eccentric portion 433 is provided on the outer sleeve 430 to further increase the amplitude generated during rotation.

[0046] See also Figure 2 and Figure 3In one embodiment, a blocking ring 422 is provided on the outlet side of the receiving hole 421 , and the blocking ring 422 is used to limit the sliding distance of the magnetic latch 440 to prevent the magnetic latch 440 from falling out of the receiving hole 421 .

[0047] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
