Detailed Description of the Embodiment

[0031] The embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0032] To better understand the above technical solution, the exemplary embodiments of the present utility model will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present utility model are shown in the drawings, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present utility model and to fully convey the scope of the present utility model to those skilled in the art.

[0033] The following will Figures 1-9 describe in detail a waterproof movement provided by the present utility model. The waterproof movement includes: a movement body 1.

[0034] Specifically, the movement body 1 has a housing 11, a rotating shaft 12, a massage head 13, at least two oil seals 14 and a cover 15. The housing 11 defines a first cavity 111 and a second cavity 112 with an open mouth. A first through hole 113 communicates between the first cavity 111 and the second cavity 112. The rotating shaft 12 is adapted to pass through the first through hole 113 from the second cavity 112 and extend out of the first cavity 111. The massage head 13 is connected to the rotating shaft 12. The oil seal 14 can be sleeved between the rotating shaft 12 and the first cavity 111 so that the oil seal 14 abuts against the outer peripheral surface of the rotating shaft 12 and the inner peripheral surface of the first cavity 111. The cover 15 has a second through hole 151, and the second through hole 151 can be sleeved on the rotating shaft 12 so that the cover 15 blocks the open mouth of the first cavity 111 and confines the oil seal 14 within the first cavity 111.

[0035] That is to say, a driving device is installed in the first cavity 111 of the housing 11 to drive the rotation of the rotating shaft 12. The rotating shaft 12 is provided to facilitate driving the massage head 13 to rotate for massage. Since the rotating shaft 12 needs to extend from the second cavity 112 through the first through hole 113 to the outside of the second cavity 112 and needs to rotate, there is a fitting gap between the rotating shaft 12 and the first through hole 113. Through the setting of the first cavity 111, the outer peripheral surface of the oil seal 14 is restricted by the first cavity 111, so that the cooperation between the oil seal 14 and the rotating shaft 12 and the housing 11 is closer, avoiding water from entering the second cavity 112 through the gap between the rotating shaft 12 and the first through hole 113 and damaging the movement. Through the sleeved cooperation between the second through hole 151 of the cover 15 and the rotating shaft 12, the large swing of the rotating shaft 12 can be restricted, preventing a gap from occurring between the rotating shaft 12 and the oil seal 14. Moreover, the cover 15 can confine the oil seal 14 within the first cavity 111, ensuring the reliability of the cooperation between the oil seal 14 and the rotating shaft 12, and thus ensuring the waterproof performance of the movement.

[0036] Thus, by means of multiple oil seals 14 cooperating with the rotating shaft 12 in the first cavity 111 of the housing 11, a seal is formed in the gap between the rotating shaft 12 and the housing 11, preventing water from entering the interior of the movement through the gap between the rotating shaft 12 and the housing 11. The oil seals 14 are restricted within the first cavity 111 by the cover body 15, ensuring the reliability of the cooperation between the oil seals 14 and the rotating shaft 12 in the first cavity 111. This waterproof movement has a simple structure and good waterproof effect, facilitating massage use during bathing.

[0037] Regarding the housing 11, the housing 11 has a first housing body 114 and a second housing body 115. The first housing body 114 and the second housing body 115 are detachably connected to jointly construct the second cavity 112, and a sealing ring 16 is provided between the first housing body 114 and the second housing body 115. It can be understood that through the split setting of the first housing body 114 and the second housing body 115, the installation of driving components such as motors can be facilitated. Through the setting of the sealing ring 16, the sealing after the installation of the first housing body 114 and the second housing body 115 can be facilitated, improving the waterproof performance of the housing 11. Among them, the first housing body 114 and the second housing body 115 can be provided with installation grooves for installing the sealing ring 16. The number of the sealing rings 16 can be two, and the two sealing rings 16 are arranged at intervals. The first housing body 114 and the second housing body 115 can be connected by screws in cooperation with sealing parts, and the positions where the screws are locked can be set on the periphery of the two sealing rings 16. In this way, seals are formed between the first housing body 114 and the second housing body 115 of the housing 11, and between the housing 11 and the rotating shaft 12, enabling the waterproof level of the movement body 1 to reach IPX8, facilitating use in water.

[0038] Regarding the first cavity 111, the first cavity 111 is arranged in the first housing body 114. The open mouth of the first cavity 111 is higher than the plane where the first housing body 114 is located, and the connection part between the first cavity 111 and the first through hole 113 is lower than the plane where the first housing body 114 is located. It can be understood that by setting the open mouth of the first cavity higher than the plane where the first housing body 114 is located and the connection part between the first cavity 111 and the first through hole 113 lower than the plane where the first housing body 114 is located, the idle position of the second cavity 112 is fully utilized, facilitating the installation of multiple oil seals 14 to improve the waterproof performance of the movement, while reducing the occupied space of the overall movement body 1, and strengthening the overall strength of the first cavity 111, facilitating the strengthening of the support for the rotating shaft 12. Among them, the first cavity 111 can be integrally formed in the first housing body 114; in addition, an LED lamp can also be provided on the first housing body 114. The LED lamp is installed in the lamp slot 116 of the first housing body 114, facilitating heating during massage. The LED lamp can be arranged in a U shape, and the LED lamp can be treated with potting seal. The waterproof level of the LED lamp can reach IPX8.

[0039] For the oil seal 14, there are two oil seals 14, and the two oil seals 14 are sleeved on the rotating shaft 12 in the first cavity 111. It can be understood that by arranging the two oil seals 14, it is convenient to further improve the sealing performance between the oil seal 14 and the rotating shaft 12 and the first cavity 111, thereby improving the waterproof performance of the movement. At the same time, it helps to support the rotating shaft 12, making the rotating shaft 12 not easily deviate, and thus the reliability of the seal. Among them, the depth of the first cavity 111 can match the thickness of the two oil seals 14 stacked, which is convenient for the cover 15 to connect to the outer shell 11 and contact the oil seal 14 at the same time. The cover 15 and the outer shell 11 can be connected by screws with seals. The oil seal 14 can be made of nitrile rubber, fluororubber, silicone rubber, acrylate rubber, polyurethane, polytetrafluoroethylene, etc.

[0040] Regarding the structure of the oil seal 14, the oil seal 14 is provided with a first annular groove 141. The inner side of the first annular groove 141 is the first sealing layer 142, and the outer side of the first annular groove 141 is the second sealing layer 143. The first sealing layer 142 is adapted to abut against the outer peripheral surface of the rotating shaft 12, and the second sealing side is adapted to abut against the inner peripheral surface of the first cavity 111. It can be understood that by arranging the first annular groove 141, the deformation of the first sealing layer 142 and the second sealing layer 143 is relatively independent, which is convenient for improving the fitting property of the oil seal 14 with the rotating shaft 12 and the first cavity 111. When the rotating shaft 12 deflects axially, the first sealing layer 142 still maintains contact with the outer peripheral surface of the rotating shaft 12 without affecting the contact between the second sealing layer 143 and the inner peripheral surface of the first cavity 111. Among them, the cross-section of the first annular groove 141 can be U-shaped.

[0041] Regarding the structure of the oil seal 14, the inner wall of the first sealing layer 142 is provided with a main sealing lip 144 and a secondary sealing lip 145 from top to bottom to jointly abut against the outer peripheral surface of the rotating shaft 12. It can be understood that by arranging the main sealing lip 144 and the secondary sealing lip 145, water and dust can be effectively isolated from entering the second cavity 112, thereby ensuring the waterproof performance of the movement. At the same time, it avoids excessive friction between the oil seal 14 and the rotating shaft 12 due to the overall contact between the first sealing layer 142 and the rotating shaft 12.

[0042] Regarding the structure of the oil seal 14, the oil seal 14 is provided with a second annular groove 146 and a third annular groove 147. The second annular groove 146 is arranged on the outer wall of the first sealing layer 142, and the third annular groove 147 is arranged adjacent to the secondary sealing lip 145. It can be understood that by arranging the second annular groove 146, it is convenient to arrange elastic components such as springs on the second annular groove 146, making the fitting property between the first sealing layer 142 and the rotating shaft 12 better, thereby ensuring the reliability of the seal. By arranging the third annular groove 147, it is convenient to improve the elasticity of the secondary sealing lip 145, so that the secondary sealing lip 145 fits better with the rotating shaft 12, thereby ensuring the reliability of the seal.

[0043] In addition, for the massage head 13, the massage head 13 includes a mounting base 131 and a massage member 132. The mounting base 131 is provided with a cylindrical connecting hole 1311 and a connecting post 1312. The connecting hole is detachably sleeved with the rotating shaft 12, and the massage member 132 is detachably sleeved with the connecting post 1311. The rotating shaft 12 and the connecting hole 1311 can be connected by a radial positioning pin to limit the relative rotation between the mounting base 131 and the rotating shaft 12, which can ensure the reliability of the axial and radial connections between the mounting base 131 and the rotating shaft 12. The number of the massage members 132 can be two, one large and one small. Ribs can be provided on the mounting base 131 to cooperate with the grooves of the massage member 132 to limit their relative rotation. Through the detachable connection between the mounting base 131 and the massage member 132 of the massage head 13, it is convenient to separately process the structurally complex massage head 13 and then assemble it, which is beneficial to cost control.

[0044] For the massager 2, it further includes a neck support member 21, and the neck support member 21 is connected to the movement body 1. It can be understood that by providing the neck support member 21, it is convenient to support the user's neck and improve the comfort of the massage of the massager 2.

[0045] For the massager 2, it further includes a covering member 22. The covering member 22 is adapted to cover the movement body 1 and the neck support member 21. The covering member 22 is provided with a suction cup 23 and a waterproof power connector 24. It can be understood that by providing the covering member 22, it is convenient to wrap the movement and the neck support, so as to prevent the internal structure from directly contacting the body, thereby improving the comfort of the massage. By providing the suction cup 23, it is convenient to adsorb the whole massager 2 on the side wall of a bathtub or a bath, which is convenient for the flexible fixation of the massager 2 to massage the user's back. Through the waterproof power connector 24, it is convenient for an external power supply to supply power to the massager 2. Among them, the neck support member 21 can be integrally formed on the covering member 22, and the neck support member 21 can form a soft connection with the waterproof movement through the covering member 22, which is convenient for folding and storing. The waterproof power connector 24 can be provided on one side of the covering member 22.

[0046] In this way, after the massager 2 adopts the above waterproof movement, the core part of the massager 2 has a waterproof function, and the waterproof level of the movement can reach IPX8, which is convenient for the massager 2 to be used while taking a bath.
