[0057] Embodiment 1

[0058] As Figure 1 and Figure 2 shown, a multifunctional massage device includes:

[0059] A housing 1;

[0060] A massage part 2, the massage part 2 having a state capable of protruding from or recessing into the housing 1;

[0061] A driving mechanism 3, the driving mechanism 3 being disposed in the housing 1, an output end of the driving mechanism 3 being connected to the massage part 2, the driving mechanism 3 being configured to drive the massage part 2 to perform a reciprocating motion;

[0062] A telescopic mechanism 4, the telescopic mechanism 4 being disposed in the housing 1 and connected to the driving mechanism 3, the telescopic mechanism 4 being configured to drive the driving mechanism 3 to telescopically move in the housing 1 and drive the massage part 2 to switch between a state of protruding from and recessing into the housing 1 through the driving mechanism 3.

[0063] The multifunctional massage device provided by the embodiment of the present invention has a state in which the massage part 2 can protrude from the housing 1 or be recessed into the housing 1. Specifically, in use, the telescopic mechanism 4 drives the driving mechanism 3 to telescopically move in the housing 1, thereby driving the massage part 2 connected to the driving mechanism 3 to telescopically move in the housing 1, realizing the conversion between the state where the massage part 2 protrudes from the housing 1 and the state where it is recessed into the housing 1. The massage part 2 makes a reciprocating motion under the drive of the driving mechanism 3, so that the massage part 2 realizes two modes of massage in the state of protruding from the housing 1 and the state of being recessed into the housing 1. When the massage part 2 is in the state of protruding from the housing 1, the massage part 2 is brought into contact with the part to be massaged, and the driving mechanism 3 drives the massage part 2 to make a reciprocating motion, and the massage part 2 can perform patting massage on the part to be massaged; when the massage part 2 is in the state of being recessed into the housing 1, a massage opening is formed at one end of the housing 1 where the massage part 2 is located. The massage part is placed over the part to be massaged, and the driving mechanism 3 drives the massage part 2 to make a reciprocating motion, generating a sucking force in the massage opening, thereby performing sucking massage on the part to be massaged in the massage opening; therefore, the multifunctional massage device can perform two modes of massage, namely patting massage and sucking massage, to achieve the effects of eliminating fatigue, stretching the skin or muscles, and achieving a health care effect; and through the conversion between the two modes of patting massage and sucking massage, precise massage can be performed on different regional parts of the human body, improving the comfort of massage, greatly enhancing the massage effect, and the two modes of patting massage and sucking massage can be quickly switched, greatly improving the convenience of use of the massage device.

[0064] In this embodiment, the telescopic mechanism 4 includes a telescopic assembly 41 and a movable part 42, and the movable part 42 is slidably arranged on the telescopic assembly 41 and fixedly connected to the driving mechanism 3.

[0065] As Figure 2 、 Figures 5 to 8 shown, the telescopic assembly 41 is provided with a first limiting part 413 and a second limiting part 414. The telescopic assembly 41 is used to drive the movable part 42 to slide and control the driving mechanism 3 to move between the first limiting part 413 and the second limiting part 414.

[0066] In this embodiment, the position of the driving mechanism 3 can be manually adjusted through the telescopic assembly 41. Specifically, when the telescopic assembly 41 moves, it drives the movable part 42 to slide on the telescopic assembly 41, thereby driving the driving mechanism 3 fixedly connected to the movable part 42 to telescopically move in the housing 1. The stroke of the driving mechanism 3 is limited between the first limiting part 413 and the second limiting part 414, so as to realize the conversion of driving the massage part 2 between the state of protruding from the housing 1 and the state of being recessed into the housing 1 through the driving mechanism 3.

[0067] The telescopic assembly 41 includes a first positioning tube 411 and a second positioning tube 412. The outer diameter of the first positioning tube 411 is smaller than the inner diameter of the second positioning tube 412. The first positioning tube 411 is installed inside the second positioning tube 412. The second positioning tube 412 can rotate relative to the first positioning tube 411 in the clockwise or counterclockwise direction. The first limiting portion 413 is provided at one end of the first positioning tube 411, and the second limiting portion 414 is provided at the other end of the first positioning tube 411. Both ends of the second positioning tube 412 are respectively connected to the first limiting portion 413 and the second limiting portion 414.

[0068] A first sliding groove 4111 is formed on the first positioning tube 411. The first sliding groove 4111 is located between the first limiting portion 413 and the second limiting portion 414. A guiding groove 4121 is formed inside the second positioning tube 412, or a guiding groove ring with a guiding groove 4121 is provided inside the second positioning tube 412. The movable portion 42 is inserted into the first sliding groove 4111 and is slidably installed in the guiding groove 4121. In this embodiment, the movable portion 42 is in the shape of a round shaft.

[0069] The first sliding groove 4111 is arranged along the axial direction of the first positioning tube 411 and has a certain length. The length of the first sliding groove 4111 is less than or equal to the distance between the first limiting portion 413 and the second limiting portion 414. Therefore, when the second positioning tube 412 rotates relative to the first positioning tube 411 in the clockwise or counterclockwise direction, it drives the movable portion 42 to slide in both the first sliding groove 4111 and the guiding groove 4121 simultaneously, and can limit the sliding of the movable portion 42 between the first limiting portion 413 and the second limiting portion 414, thereby restricting the stroke of the driving mechanism 3 between the first limiting portion 413 and the second limiting portion 414.

[0070] One end of the first sliding groove 4111 close to the first limiting portion 413 is provided with a first corner 4112 arranged along the circumferential direction of the first positioning tube 411, and the other end of the first sliding groove 4111 close to the second limiting portion 414 is provided with a second corner 4113 arranged along the circumferential direction of the first positioning tube 411. One of the first corner 4112 and the second corner 4113 is arranged along the clockwise circumferential direction of the first positioning tube 411, and the other is arranged along the counterclockwise circumferential direction of the first positioning tube 411. For example, the first corner 4112 is arranged along the clockwise circumferential direction of the first positioning tube 411, and the second corner 4113 is arranged along the counterclockwise circumferential direction of the first positioning tube 411. Thus, when the second positioning tube 412 rotates relative to the first positioning tube 411 in the clockwise or counterclockwise direction, the movable portion 42 can slide in the first sliding groove 4111 and slide to the first corner 4112 or the second corner 4113.

[0071] Combined with Figure 9, the driving mechanism 3 is arranged inside the first positioning tube 411; the second positioning tube 412 rotates relative to the first positioning tube 411 in the counterclockwise or clockwise direction, driving the movable part 42 to slide in the first chute 4111 and the guide groove 4121 simultaneously, so as to drive the driving mechanism 3 to move inside the first positioning tube 411. When the movable part 42 enters the first corner 4112, the second positioning tube 412 stops rotating relative to the first positioning tube 411, and the driving mechanism 3 is fixed at the corresponding position of the first limiting part 413 of the first positioning tube 411; it can be understood that the first positioning tube 411 can also rotate relative to the second positioning tube 412 in the counterclockwise or clockwise direction. In this embodiment, the rotation of the second positioning tube 412 relative to the first positioning tube 411 is taken as an example for illustration; for example, when the second positioning tube 412 rotates relative to the first positioning tube 411 in the counterclockwise direction, the guide groove 4121 of the second positioning tube 412 drives the movable part 42 to slide along the first chute 4111 in the direction towards the first corner 4112, so as to drive the driving mechanism 3 fixedly connected to the movable part 42 to move inside the first positioning tube 411. When the movable part 42 enters the first corner 4112, the movable part 42 will be restricted within the first corner 4112, and the second positioning tube 412 stops rotating relative to the first positioning tube 411, that is, the second positioning tube 412 cannot continue to rotate relative to the first positioning tube 411 in the counterclockwise direction, and the second positioning tube 412 can only rotate relative to the first positioning tube 411 in the clockwise direction; at this time, since the movable part 42 is restricted within the first corner 4112, the driving mechanism 3 will be fixed at the corresponding position of the first limiting part 413 of the first positioning tube 411, that is, the position of the movable part 42 is restricted by the first corner 4112, thereby realizing the restriction of the position of the driving mechanism 3 in the first positioning tube 411.

[0072] The second positioning tube 412 rotates clockwise or counterclockwise relative to the first positioning tube 411, driving the movable part 42 to slide in the first chute 4111 and the guide chute 4121 simultaneously, so as to drive the drive mechanism 3 to move in the first positioning tube 411. When the movable part 42 enters the second corner 4113, the second positioning tube 412 stops rotating relative to the first positioning tube 411, and the drive mechanism 3 is fixed at the corresponding position of the second limiting part 414 of the first positioning tube 411. For example, when the second positioning tube 412 rotates clockwise relative to the first positioning tube 411, the guide chute 4121 of the second positioning tube 412 drives the movable part 42 to slide on the first chute 4111 in the direction towards the second corner 4113, so as to drive the drive mechanism 3 fixedly connected to the movable part 42 to move in the first positioning tube 411. When the movable part 42 enters the second corner 4113, the movable part 42 will be restricted within the second corner 4113, and the second positioning tube 412 stops rotating relative to the first positioning tube 411, that is, the second positioning tube 412 cannot continue to rotate clockwise relative to the first positioning tube 411, and the second positioning tube 412 can only rotate counterclockwise relative to the first positioning tube 411. At this time, since the movable part 42 is restricted within the second corner 4113, the drive mechanism 3 will be fixed at the corresponding position of the second limiting part 414 of the first positioning tube 411, that is, the position of the movable part 42 is restricted by the second corner 4113, thereby realizing the restriction of the position of the drive mechanism 3 in the first positioning tube 411.

[0073] Combined with Figure 10 , when the drive mechanism 3 is fixed at the corresponding position of the first limiting part 413 of the first positioning tube 411, the massage part 2 is in a state of protruding from the housing 1. Since the massage part 2 is connected to the drive mechanism 3, when the second positioning tube 412 rotates counterclockwise relative to the first positioning tube 411, the guide chute 4121 of the second positioning tube 412 drives the movable part 42 to slide on the first chute 4111 in the direction towards the first corner 4112, thereby driving the massage part 2 connected to the drive mechanism 3 to move in the direction of protruding from the housing 1. When the movable part 42 enters the first corner 4112, the drive mechanism 3 is fixed at the corresponding position of the first limiting part 413 of the first positioning tube 411, making the massage part 2 in a state of protruding from the housing 1.

[0074] When the driving mechanism 3 is fixed at the second limiting portion 414 of the first positioning tube 411, the massage portion 2 is in a state sunken into the housing 1. Since the massage portion 2 is connected to the driving mechanism 3, when the second positioning tube 412 rotates clockwise relative to the first positioning tube 411, the guide groove 4121 of the second positioning tube 412 drives the movable portion 42 to slide on the first sliding groove 4111 in the direction towards the second corner 4113, thereby driving the massage portion 2 connected to the driving mechanism 3 to move in the direction of being sunken into the housing 1. When the movable portion 42 enters the second corner 4113, the driving mechanism 3 is fixed at the corresponding position of the second limiting portion 414 of the first positioning tube 411, so that the massage portion 2 is in a state sunken into the housing 1. Therefore, by the relative rotation of the second positioning tube 412 and the first positioning tube 411, the massage portion 2 can be quickly switched between the state of protruding from the housing 1 and the state of being sunken into the housing 1, so as to quickly switch between the two modes of patting massage and sucking massage, greatly improving the use convenience of the massage device.
