Technical Field

[0001] The utility model belongs to the technical field of daily necessities, and in particular relates to a combined massage stick. Background Art

[0002] Massage sticks are one of the common daily necessities. Existing massage sticks can often only control the frequency of vibration by changing the current of the vibration motor, but cannot change the amplitude of vibration. The main reason is that the eccentric vibration head connected to the motor cannot be replaced. This structure causes the problem of a single vibration adjustment mode of the massage stick, affecting the user experience. Therefore, it is necessary to design a massage stick structure with a replaceable eccentric vibration head to achieve amplitude change of the massage stick. Utility Model Content

[0003] In order to solve the problem that the vibration amplitude of the existing massage stick is difficult to change, the present solution provides a combined massage stick.

[0004] The technical solution adopted by the utility model is:

[0006] As an alternative or supplement to the above-mentioned combined massage stick: a locking pin is provided on the side wall of the eccentric vibration head; the locking pin is threadedly connected to the eccentric vibration head and can vertically press against the motor shaft.

[0007] As an alternative or supplement to the above-mentioned combined massage stick: the front end of the vibration inner core is provided with an external threaded portion, and the cap opening of the protective cap is provided with an internal threaded portion that matches the external threaded portion.

[0008] As an alternative or supplement to the above-mentioned combined massage stick: the vibration inner core is cylindrical and has a built-in battery for powering the DC motor.

[0009] As an alternative or supplement to the above-mentioned combined massage stick: the front end of the protective cap is semi-spherical.

[0010] As an alternative or supplement to the above-mentioned combined massage stick: the outer surface of the front end of the silicone jacket is provided with a plurality of convex rubber particles.

[0011] As an alternative or supplement to the above-mentioned combined massage stick: the vibration inner core outer shell is provided with one or more layers of rubber inner shells, and the silicone outer shell is arranged outside the rubber inner shell and covers the entire rubber inner shell.

[0012] As an alternative or supplement to the above-mentioned combined massager: the rubber inner sleeve has only one layer, a rear airbag is arranged in the side wall of the rear part of the rubber inner sleeve, and a front airbag is arranged in the side wall of the front part of the rubber inner sleeve; the rear airbag is connected to the front airbag through a channel in the side wall of the rubber inner sleeve.

[0013] The beneficial effects of the utility model are as follows: in this scheme, the vibration amplitude of the massage stick can be changed through the replaceable eccentric vibration head, and the power supply current of the DC motor can be changed as needed, thereby achieving dual changes in vibration frequency and vibration amplitude, thereby meeting the needs of different people for different vibration sensations and improving the user experience.

[0021] The technical solution in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings. The described embodiments are only some of the embodiments, not all of them. Based on the embodiments in this solution, all other embodiments obtained by ordinary technicians in this field without making creative work are within the protection scope of this solution.

[0022] Example 1

[0023] like Figures 1 to 5 As shown, this embodiment designs a combined massage stick, including a vibration inner core 1, a protective cap 2, an eccentric vibration head 5 and a silicone outer cover 4 and other components.

[0024] A DC motor and a battery are arranged in the vibration inner core 1. The vibration inner core 1 is cylindrical. The battery can supply power to the DC motor. A switch and a current regulator are arranged on the circuit between the DC motor and the battery, so as to control and adjust the rotation speed of the DC motor as needed.

[0025] The motor shaft 11 of the DC motor extends from the front end of the vibration inner core 1 and is connected to the eccentric vibration head 5; the eccentric vibration head 5 is detachably connected to the motor shaft 11; a locking nail 6 is provided on the side wall of the eccentric vibration head 5; the locking nail 6 is threadedly connected to the eccentric vibration head 5 and can vertically press against the motor shaft 11. By replacing different eccentric vibration heads 5, the vibration amplitude of the vibration inner core 1 can be changed to meet different usage requirements.

[0026] The protective cap 2 is arranged outside the eccentric vibration head 5. The front end of the protective cap 2 is semi-spherical, so as to avoid the edges and corners from scratching the skin. The protective cap 2 is threadedly connected to the front end of the vibration inner core 1, which effectively improves the reliability of the connection and prevents the protective cap 2 from falling off. The front end of the vibration inner core 1 is provided with an external threaded portion, and the cap opening of the protective cap 2 is provided with an internal threaded portion that matches the external threaded portion.

[0027] The silicone coat 4 is inserted into the vibration core 1 and covers the vibration core 1. The outer surface of the front end of the silicone coat 4 is provided with a plurality of convex rubber particles 41. The silicone material used in the silicone coat 4 has better skin-friendliness, and the convex rubber particles 41 can stimulate the skin and improve the use experience.

[0028] One or more layers of rubber inner sleeves 3 are provided on the outer cover of the vibration inner core 1, and the silicone outer sleeve 4 is provided outside the rubber inner sleeve 3 and covers the entire rubber inner sleeve 3. By adding different numbers of rubber inner sleeves 3, the diameter of the massage stick can be changed.

[0029] When the rubber inner sleeve 3 has only one layer, a rear airbag 31 may be provided in the side wall of the rear portion of the rubber inner sleeve 3, and a front airbag 32 may be provided in the side wall of the front portion of the rubber inner sleeve 3; the rear airbag 31 and the front airbag 32 are connected through a channel in the side wall of the rubber inner sleeve 3. When the rear end of the rubber inner sleeve 3 is held and squeezed hard, the air in the rear airbag 31 can be squeezed into the front airbag 32, thereby changing the diameter of the front airbag 32.

[0030] The above embodiments are merely examples for the purpose of clarifying the description, and are not intended to limit the implementation methods; it is not necessary and impossible to list all implementation methods exhaustively. However, obvious changes or modifications derived therefrom are still within the scope of protection of the present technology.
