[0024] In the solution of the present invention, the air pressure in the cavity is adjusted by the air pump assembly, so that the airbag deforms in the cavity. The deformation of the airbag causes the suction nozzle to generate an air flow, making the sucking massage effect softer. Moreover, by controlling the air pumping / air intake of the cavity by the air pump assembly, the force control is more uniform and precise. At the same time, the vibrating rod disposed between the suction nozzle and the airbag can be controlled to vibrate while sucking, enriching the massage effect. In addition, the suction nozzle is movably installed on the opening of the massage end opening part, which is convenient for replacing the suction nozzle in contact with the human body in the massager and keeping it clean.

[0025] Please refer to Figure 1 and Figure 2 As shown in and, a massager provided by an embodiment of the present invention includes a housing main body 1, an air pump assembly 2, a massage assembly 3 and a control circuit board 4 disposed inside the housing main body 1. Among them, the housing main body 1 is composed of an upper housing aa and a lower housing bb which are fastened and fixed up and down. The housing main body 1 is integrally in an "L" shape, including a massage end 10 and a hand-held end 11. On the side near the massage function, the massage end 10 is arc-connected to the side of the hand-held end 11 near the massage function. A silicone sleeve cc can be sleeved on the outer surface of the housing main body 1 to improve the holding feel.

[0026] Please refer to together with Figure 3 and Figure 4 As shown in and, the massage end 10 of the housing main body 1 is provided with an opening part 100 with one end open. Along the opening part downward, a receiving cavity is formed inside the massage end 10, and a receiving cavity is also formed inside the hand-held end 11. Among them, the air pump assembly 2 and the control circuit board 4 are disposed in the receiving cavity inside the hand-held end 11.

[0027] The massage component 3 includes a cavity 30, an airbag 31, a suction nozzle 32, and a vibrating rod 33. Among them, the cavity 30 is placed in the accommodation cavity formed inside the massage end 10. One end of the cavity 30 near the opening is open, and the other end is closed. The open end of the cavity 30 is hermetically connected to the airbag 31. The suction nozzle 32 is movably installed on the opening of the opening part 100, and the vibrating rod 33 is placed between the suction nozzle 32 and the airbag 31. The vibrating rod 33 is electrically connected to the control circuit board 4 and can be controlled by it to vibrate, so as to generate stimulation to the massage part of the human body through the suction nozzle 32. The suction nozzle 32 can be made of silica gel material and can be designed into different shapes according to needs.

[0028] The cavity 30 is provided with air holes. Through the air holes, the cavity 30 is connected to the air pump assembly 2. The air pump assembly 2 is electrically connected to the control circuit board 4 and is controlled by it. The air pump assembly 2 pumps air into or out of the cavity 30 through the air holes, so that the air pressure in the cavity 30 changes. As the air pressure in the cavity 30 changes, the airbag 31 will deform correspondingly in the cavity 30, so that an air flow is generated in the suction nozzle 32, and the suction nozzle generates a sucking action.

[0029] In the embodiment of the present invention, the air pressure in the cavity is adjusted under the drive of the air pump assembly, so that the airbag deforms in the cavity. The deformation of the airbag causes an air flow to be generated in the suction nozzle, making the sucking massage effect softer. At the same time, by controlling the air pumping / air intake of the cavity by the air pump assembly, the strength control is more uniform and precise. In addition, the vibrating rod arranged between the suction nozzle and the airbag can be controlled to vibrate while sucking, enriching the massage effect. In addition, the suction nozzle is movably installed on the opening of the opening part of the massage end, which is convenient for replacing the suction nozzle in contact with the human body in the massager and keeping it clean.

[0030] Driven by the air pump assembly 2, by adjusting the air pressure in the cavity 30, the airbag 31 deforms in the cavity 30, thereby generating an air flow to cause the suction nozzle 32 to achieve sucking. In the embodiment of the present invention, the air pump assembly 2 includes an air pump 20, a solenoid valve 21, a three-way pipe 22, an air inlet pipe 23, an exhaust pipe 24, and a connecting pipe 25. Among them, there are two connecting pipes on the air pump 20. One end of the air inlet pipe 23 is communicated with one of the connecting pipes on the air pump 20, and the other end is connected to one end of the three-way pipe 22 and is connected to the solenoid valve 21 through the other end of the three-way pipe 22. The three-way pipe 22 and the solenoid valve 21 can be connected by a silica gel pipe. At the same time, the solenoid valve 21 is also connected with a silica gel pipe for air intake; the remaining end of the three-way pipe 22 is connected to the connecting pipe 25, and the other end of the connecting pipe 25 is connected to it through the air hole on the cavity 30; the other connecting pipe of the air pump 20 is connected to the exhaust pipe 24. The air pump 20 is a negative pressure air compressor, controlled by the control circuit board 4. When the solenoid valve 21 is closed, the silica gel pipe between the three-way valve 22 and the solenoid valve 21 is closed. The air pump 21 acts, and the air in the cavity 30 enters the air pump 20 through the connecting pipe 25, the three-way valve 22, and the air inlet pipe 23, and is extracted through the exhaust pipe 24; when the solenoid valve 21 is opened, air enters the three-way pipe 22 through the solenoid valve 21. Part of the gas enters the air pump 20 through the air inlet pipe 23, and part of the gas enters the cavity 30 through the connecting pipe 25. The closing and opening of the air valve 21 cause the air pressure in the cavity 30 to change, so that the suction nozzle 32 realizes sucking. By controlling the closing frequency of the air valve 21, different sucking frequencies of the suction nozzle 32 can be realized.

[0031] In the embodiment of the present invention, the air pump assembly is used to adjust the internal air pressure of the cavity. During the adjustment process, the change of the air pressure can be continuous and fine, so that when the suction effect caused by the deformation of the airbag makes the suction nozzle generate a sucking effect, the force control can be more uniform and fine.

[0032] Please refer to Figure 4 and Figure 5 , the airbag 31 is a silica gel body, including a fixing part 310 and an elastic part 311. The fixing part 310 is hermetically connected to the opening of the cavity 30, so that the elastic part 311 is placed in the opening area of the cavity 30. The elastic part 311 is composed of several annular segments. When the air pump assembly 2 pumps air out of the cavity 30 and the air pressure in the cavity 30 changes from normal atmospheric pressure to negative pressure, the annular segments of the elastic part 311 gradually expand in the cavity 30, and its shape is as shown in Figure 5 ; when the air pump assembly 2 intakes air into the cavity 30 and the air pressure in the cavity 30 changes from negative pressure to normal atmospheric pressure, the annular segments of the elastic part 311 gradually contract in the cavity 30. When it contracts to return to its original state, its shape is as shown in Figure 4 . As the airbag 31 expands and contracts in the cavity 30, a pulsating suction force is generated in the cavity of the suction nozzle 32, acting on the human body part to generate a sucking action.

[0033] In the embodiment of the present invention, the elastic part of the airbag is composed of several rings of annular ends. When the air pressure in the cavity is negative pressure, the annular segments expand and can occupy the volume of the cavity to the maximum extent, so as to enable the suction nozzle to generate sufficient air flow and ensure the strength effect of the sucking action.

[0034] The opening part 100 of the massage end 10 includes, from top to bottom, a first accommodation cavity 1000, a second accommodation cavity 1001 and a third accommodation cavity 1002 that are connected in sequence, and the three are located on the same central axis.

[0035] The suction nozzle 32 is sleeved on the opening of the first accommodation cavity 1000. The suction nozzle 32 includes an inner silicone layer 320 and an outer silicone layer 321, and an inverted "V" - shaped gap space is formed between the inner silicone layer 320 and the outer silicone layer 321. An annular protrusion 3210 is provided on the inner wall of the outer silicone layer 321 of the inverted "V" - shaped gap space. Correspondingly, an annular groove is provided on the outer peripheral surface of the first accommodation cavity 1000, and the annular protrusion 3210 cooperates with the annular groove to fasten the suction nozzle 32 and the first accommodation cavity 1000.

[0036] The connection between the third accommodation cavity 1002 and the second accommodation cavity 1001 is at a right angle. The cavity 30 is snapped into the third accommodation cavity 1002. The second accommodation cavity 1001 and the cavity 30 are located on the same central axis and have the same aperture size. In the embodiment of the present invention, the cavity 30 includes an annular part 300 provided around its outer surface, and a first end part 301 and a second end part 302 with the same aperture size separated by the annular part 300, and the first end part 301 is open. A plurality of tooth holes are provided on the annular part 300. A plurality of strip - shaped silicone strips (not shown in the figure) that can be snapped with the tooth holes may also be connected to the surface of the fixing part 310 of the airbag 31. The cavity 30 is fixed by the cooperation of the tooth holes on the annular part 300 and the gear protrusions on the inner wall of the third accommodation cavity 1002, and at the same time, the silicone strips are stretched and snapped into the tooth holes of the corresponding annular part 300 of the cavity 30. The cavity 30 is fixed in the third accommodation cavity 1002. At this time, the fixing part 310 of the airbag 31 that is hermetically connected to the cavity 30 abuts against the right - angle connection between the third accommodation cavity 1002 and the second accommodation cavity 1001.

[0037] In the embodiment of the present invention, by fixing the cavity, the airbag abuts tightly against the right - angle connection between the third accommodation cavity and the second accommodation cavity, and combined with the silicone strips connected to the surface of the airbag being snapped into the tooth holes on the outer periphery of the cavity, the loosening of the airbag on the cavity is avoided, so that the deformation action generated with the change of the air pressure in the cavity will not be weakened, thus ensuring the sucking and massaging effect of the suction nozzle.

[0038] The longitudinal section of the second accommodation cavity 1001 is rectangular, and the longitudinal section of the first accommodation cavity 1000 is an inverted trapezoid that is wider at the top and narrower at the bottom. The second accommodation cavity 1001 and the adjacent first accommodation cavity 1000 form a trumpet-shaped air flow channel. The air flow generated by the deformation of the elastic part of the airbag 31 in the cavity 31 enters the inner silica gel layer of the suction nozzle 32 through this trumpet-shaped air flow channel, so as to make the suction nozzle 32 produce a sucking and massaging effect.

[0039] The massage assembly 3 further includes a waterproof and breathable membrane 34 disposed between the suction nozzle 32 and the airbag 31. In the embodiment of the present invention, the waterproof and breathable membrane 34 is disposed on the vibrator 33 and is arranged in a fitting manner.

[0040] In the embodiment of the present invention, by providing a waterproof and breathable membrane between the suction nozzle and the airbag, it is possible to prevent the liquid or debris on the human skin from penetrating into the airbag through the suction nozzle during massage, causing pollution of the airbag.

[0041] In the massager provided by the embodiment of the present invention, the air pressure in the cavity is adjusted under the drive of the air pump assembly, so that the airbag deforms in the cavity. The deformation of the airbag then causes the suction nozzle to generate an air flow, making the sucking and massaging effect softer. At the same time, by controlling the air extraction / air intake of the cavity by the air pump assembly, the force control is more uniform and precise. In addition, the vibrator disposed between the suction nozzle and the airbag can be controlled to vibrate while sucking, enriching the massage effect. Furthermore, the suction nozzle is movably installed at the opening of the massage end, which is convenient for replacing the suction nozzle in contact with the human body in the massager and maintaining cleanliness.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
