The head massager generally includes a first housing and a second housing, and the screw assembly drives the action mechanism to push the first housing and the second housing to bring the first housing and the second housing closer to or away from each other. , to achieve size adjustment, which is suitable for different users of the application. The pitch adjusting device of the present invention and the head massager having the adjusting structure will be described in detail below with reference to specific embodiments.

 As shown in FIG. 1 and FIG. 5, in the first embodiment of the head massager of the present invention, the first housing 110 and the second housing 120 are separated into two parts, and are substantially hemispherical. A hemispherical internal setting massage device (not shown), in order to adjust the distance between the first housing 110 and the second housing 120, on the top and sides of the first housing 110 and the second housing 120 Three spacing adjustment devices 130 for connecting the first housing 110 and the second housing 120 are provided, respectively. Of course, the pitch adjusting devices 130 may be one, two or more, and the number thereof may be adjusted according to actual needs.

 [58] Referring to Figures 1 to 5, one of the pitch adjusting devices is taken as an example to describe in detail how the pitch adjusting device is implemented. The pitch adjusting device includes a housing, a screw assembly, an action mechanism, and the like.

In the present embodiment, the outer casing is mounted at a joint position of the first casing 110 and the second casing 120, and the first casing 110 and the second casing 120 are movable relative to the outer casing. The outer casing serves as the outer casing of the entire pitch adjusting device 130, thereby functioning as a screw assembly, an action mechanism, and the like. The housing includes a base 135 and a cover 136. The base 135 and the cover 136 can be coupled to both sides of the first housing 110 and the second housing 120 by various mechanisms such as screws, bolts, rivets, snaps, and the like. An accommodating space 1361 for accommodating the screw assembly is formed between the cover 136 and the base 135, as shown in FIG. 3 and FIG. 4, and is used on the cover 136. The third through hole 1362 passes through the screw 131. It can be understood that the outer casing can also be integrally formed with the first housing 110 or the second housing 120. The screw 131 can be a ball screw, so that the adjustment can be more labor-saving; of course, other forms of the screw can also be used.

[60] The action mechanism includes a first connecting piece 111 disposed on the first housing 110, a second connecting piece 121 disposed on the second housing 120, and disposed between the first connecting piece and the second connecting piece Elastic reset and rotating handle.

 [61] The first connecting piece 111 and the second connecting piece 121 are provided with corresponding first through holes 112 and second through holes 122, and corresponding to the third through holes 1362 on the outer casing, so as to facilitate screw wear. Over. The first connecting piece 111 and the second connecting piece 121 are inserted into the receiving space 1361 of the cover body 136, and the outer side of the first connecting piece 111 is pushed against the inner end surface of the receiving space 1361 by the elastic returning member provided, and The outer side of the two connecting pieces 121 abuts against the inner end surface of the rotary handle 133; and the rotating handle 133 is disposed outside the second connecting piece 121 and protrudes from the accommodating space 1361. The second connecting piece 121 is moved toward or away from the first connecting piece 111 by operating the rotating handle 133, thereby adjusting the distance between the first housing 110 and the second housing 120.

 [62] It can be understood that the first connecting piece 111 and the first housing 110 can be an integrally formed structure, or a structure in which a separate member is fixed on the housing, and the second connecting piece 121 and the second housing 120. The structure is the same.

 [63] The elastic returning member spring 134 is disposed between the first connecting piece 111 and the second connecting piece 121 to provide an elastic restoring force. Since the first through hole 112 and the second through hole 122 are through holes, the first through hole 112 and the second through hole 122 are through holes. A connecting piece 111 and a second connecting piece 121 are slidable relative to the screw 131, and the spring 134 is disposed such that the position of the screw 131 and the rotating handle 133 are relatively fixed, so that the first connecting piece 111 and the second connecting piece 121 can be respectively respectively The inner end surface of the accommodating space 1341 and the inner end surface of the handle 133 are positioned such that the positions of the two connecting pieces are relatively positioned with the screw.

 [64] Further, the rotating handle 133 may further be provided with a non-slip structure 1332. The anti-slip structure 1332 may be a stripe-shaped protrusion or a groove, so that the rotating handle 133 is operated, and the phenomenon of slipping is less likely to occur.

 [65] The screw assembly includes a screw 131 having a head 132 and a screw hole 1331 that engages the screw 131. In the present embodiment, the screw hole 1331 is provided on the rotary handle 133 and is engaged with the end of the screw 131. The head portion 132 of the screw 131 is disposed outside the cover body 136 to prevent the screw 131 from coming off.

[66] The first connecting piece 111 and the second connecting piece 121 are disposed in the receiving space 1361 of the cover 136. And the spring 134 is disposed between the first connecting piece 111 and the second connecting piece 121; then, the screw 13 1 is sequentially passed through the third through hole 1362, the first through hole 112, the spring 134, and the second through hole 122. The screw hole 1331 on the rotary handle 1 33 is aligned with the screw 131, and the rotary handle 133 is screwed to the end of the screw 131.

[67] After the distance 吋 between the first housing 110 and the second housing 120 needs to be pulled, the handle 13 3 is rotated in one direction, so that the screw 131 is further screwed into the screw hole 1331, and the second handle is pushed by the rotating handle 133. The connecting piece 121 is adjacent to the first connecting piece 111 and simultaneously compresses the spring 134 to achieve a distance between the first housing 110 and the second housing 120.

 [68] When it is necessary to adjust the distance 第一 between the first housing 110 and the second housing 120, the handle 13 3 is rotated in the other direction, so that the screw 131 partially rotates out of the screw hole 1331, and then, at the spring 134 Under the action of the elastic restoring force, the second connecting piece 121 is pushed away from the first connecting piece 111, thereby increasing the distance between the first housing 110 and the second housing 120.

It is a screw hole of the screw assembly, and the rotary handle in the first embodiment is omitted. Further, a retaining hole 2363 may be left in the right side of the housing 236 to allow the portion of the screw 231 to be rotated out of the second connecting piece 221. Also, the second connecting piece 221 and the second outer casing 220 are movable relative to the base 235 and the cover 236.

 [71] After the distance between the first housing 210 and the second housing 220 needs to be adjusted, only the head 2 32 of the screw 231 needs to be operated to rotate the screw 231 in the forward or reverse direction, since the second through hole 222 is The screw 231 engages with the screw hole, so that the second connecting piece 221 moves toward or away from the first connecting piece 211 under the driving of the screw 231, thereby adjusting the distance between the first housing 210 and the second housing 220. . Of course, it is also possible to provide a spring 234 between the first connecting piece 211 and the second connecting piece 221 or not to provide a spring (for example, the first connecting piece 211 is fixedly connected with the housing 236 to ensure the relative positioning of the first connecting piece 211 and the screw 231). You can).

It can be understood that the first through hole on the first connecting piece can also be used as a screw hole that engages with the screw, and then the first housing and the first connecting piece can be moved relative to the base and the cover; or, a through hole and a second through hole are designed as screw holes that mesh with the screw, and the first through hole and the second through hole have opposite spiral directions, so that the first connecting piece and the second connection can be driven when the screw 拧 is turned The piece moves relative to or back, The distance between the first housing and the second housing is further adjusted; the spring may not require a spring, and the threaded connection enables the first tab and the second tab to be positioned relative to the screw.
