【Detailed ways】

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Embodiment one

Please refer to FIG. 1 and FIG. 2 together. The negative pressure massager includes a housing 1 and a negative pressure generator 3 . The negative pressure generator 3 is installed in the housing 1 and the suction port 333 of the negative pressure generator 3 is exposed from the housing 1 .

The negative pressure generator 3 includes a first housing 31 , a flexible body 33 , a negative pressure source 34 and an exhaust pipe 35 .

The first housing 31 has an accommodating chamber 31A and a communication passage 31B communicating with the accommodating chamber 31A.

The flexible body 33 is accommodated in the accommodation cavity 31A. The flexible body 33 has a massage cavity 331 , an adsorption port 333 and a through hole 335 disposed on the massage cavity 331 . The through hole 335 communicates with the communication channel 31B. Wherein, the flexible body 33 is made of elastically deformable flexible material, and the suction port 333 is used to be placed on the parts of the human body that need to be massaged (such as the back of the hand and the back).

The negative pressure source 34 is used to generate negative pressure.

The suction pipe 35 communicates with the negative pressure source 34 and the communication channel 31B.

During use, the suction port 333 is placed on the position of the human body that needs to be massaged (such as the back of the hand, the back), and the negative pressure source 34 works and sequentially sucks the air in the massage chamber 331 through the air extraction pipe 35, the communication channel 31B and the through hole 335 so that The suction port 333 generates negative pressure to absorb the skin of the massaged part of the human body, thereby achieving a massage effect. At the same time, because the flexible body 33 can deform under the action of negative pressure and squeeze the skin of the massaged part of the human body, it can also achieve kneading. The effect of massage.

In this embodiment, the negative pressure source 34 is an air pump, and the air pump 34 has an air suction port 341 communicated with the air suction pipe 35 and an exhaust port 343 communicated with the outside.

In this embodiment, the negative pressure generator 3 also includes an air intake pipe 37 and a switch valve 39 , one end of the air intake pipe 37 communicates with the massage chamber 331 , and the other end communicates with the outside world. Wherein, the on-off valve 39 can be an electromagnetic on-off valve.

As shown in the figure, the air intake pipe 37 communicates with the air extraction pipe 35 so that the air intake pipe 37 communicates with the massage chamber 331 through the air extraction pipe 35 , the communication channel 31B and the through hole 335 in sequence. That is to say, the air intake pipe 37 communicates indirectly with the massage chamber 331 .

During the working process of the negative pressure source 34 of the negative pressure massager, the periodic opening and closing of the switch valve 39 can periodically generate negative pressure at the suction port 333 so that the suction port 333 continuously absorbs and relaxes the skin of the massaged part of the human body. Specifically, during the working process of the negative pressure source 34, the negative pressure source 34 sequentially sucks the air in the massage chamber 331 through the air suction pipe 35, the communication channel 31B and the through hole 335 so that the suction port 333 generates negative pressure to absorb the massage parts of the human body. At the same time, during the working process of the negative pressure source 34, the switch valve 39 is periodically opened and closed, and the outside air enters through the intake pipe 37, the exhaust pipe 35, the communication channel 31B and the through hole 335 in sequence when the switch valve 39 is opened. The massage chamber 331 of the flexible body 33 is to break the negative pressure state of the massage chamber 331. When the negative pressure state of the massage chamber 331 is broken, the suction port 333 relaxes the skin of the massaged part of the human body; after that, the switching valve 39 is closed to prevent external The air enters the massage cavity 331 of the flexible body 33 to make the massage cavity 331 re-form a negative pressure. That is to say, the massage cavity 331 can adjust the absorption or relaxation of the massage part of the human body by periodically opening and closing the switching valve 39 of the negative pressure source 34, so as to achieve the massage effect of absorption and relaxation.

In this embodiment, the first housing 31 and the flexible body 33 are detachably connected.

Embodiment two

Please refer to FIG. 3 to FIG. 5 . The difference between the second embodiment and the first embodiment is that the first housing 31 includes a housing main body 311 that encloses and forms an accommodating cavity 31A and is fixed on the side of the housing main body 311 away from the accommodating cavity 31A. The gland 313, the communication channel 31B includes a first channel 31C that runs through the shell body 311 and communicates with the through hole 335, and a second channel 31D that is located on the gland 313 and communicates with the first channel 31C and the exhaust pipe 35. The shell body 311 A waterproof filter structure 4 located on the communication channel 31B is sandwiched between the gland and the gland 313 .

In this embodiment, the gland 313 is fixed on the housing body 311 by fasteners (eg, screws or bolts).

In this embodiment, the waterproof filter structure 4 is an elastic membrane. Wherein, the elastic membrane can communicate with the first channel 31C and the second channel 31D when the negative pressure source 34 is working and the switch valve 39 is closed, thereby making the communication channel 31B conduct; and when the negative pressure source 34 stops working or breaks the massage chamber 331 In the negative pressure state, the communication between the first channel 31C and the second channel 31D can be blocked, thereby blocking the communication channel 31B. Such arrangement can effectively prevent external liquid water or gaseous water from entering the shell 1 through the adsorption port 333 , the massage chamber 331 , the through hole 335 , the communication channel 31B, the exhaust pipe 35 and the negative pressure source 34 in sequence.

Specifically, the elastic membrane includes a blocking portion 41 , a fixing portion 43 disposed around the blocking portion 41 and interposed between the shell body 311 and the gland 313 , and a plurality of gaps and connecting the blocking portion 41 and the fixing portion 43 . The elastic connecting part 45 . When the on-off valve 39 is closed and the negative pressure source 34 is working, the blocking portion 41 moves into the second passage 31D under the effect of the negative pressure generated by the negative pressure source 34 so that the first passage 31C and the second passage 31D are connected and elastic. The connecting portion 45 is elastically deformed. Wherein, since the first channel 31C and the second channel 31D are in communication, the negative pressure source 34 can sequentially suck the air in the massage chamber 331 through the suction pipe 35, the communication channel 31B and the through hole 335 to make the suction port 333 generate negative pressure. And absorb the skin of the massaged part of the human body. When the switch valve 39 is opened and the negative pressure source 34 is working, since the outside air enters the second channel 31D through the intake pipe 37 and the exhaust pipe 35 in turn, the blocking part 41 will lose the negative pressure acting on it. Therefore, at this time, the elastic The connecting portion 45 returns to elastic deformation under its own deformation force so that the blocking portion 41 moves toward the first channel 31C to cover the first channel 31C, thereby blocking the communication between the first channel 31C and the second channel 31D. Wherein, during the recovery deformation process of the elastic connecting portion 45 (or in other words, the blocking portion 41 moves toward the first channel 31C to cover the first channel 31C), the first channel 31C and the second channel 31D are still connected, and enter The outside air of the second channel 31D also enters the massage cavity 331 of the flexible body 33 through the first channel 31C and the through hole 335 in order to break the negative pressure state of the massage cavity 331, that is, when the negative pressure state of the massage cavity 331 is broken, the elastic membrane Communication between the first channel 31C and the second channel 31D can be blocked. When the negative pressure source 34 stops working, the blocking portion 41 loses the negative pressure acting on it, and at this moment, the blocking portion 41 is in a position covering the first channel 31C, that is, the elastic mold blocks the first channel 31C and the second channel 31C. The connection of the two channels 31D.

In this embodiment, the casing 1 is provided with an air hole 13 , and the exhaust port 343 communicates with the air hole 13 through the exhaust pipe 15 . Such setting not only enables the negative pressure source 34 to exhaust to the outside through the air hole 13, but also when the external liquid water or gaseous water enters the negative pressure through the adsorption port 333, the massage chamber 331, the through hole 335, the communication channel 31B and the exhaust pipe 35 When the source 34 is used, the negative pressure source 34 can also discharge the liquid out of the casing 1 through the exhaust pipe 15 and the air hole 13, thereby further preventing the liquid from entering the circuit in the casing 1 and causing a short circuit.

Embodiment three

Please refer to FIG. 6 , the difference between the third embodiment and the second embodiment is that the waterproof filter structure 4 is a gas-permeable isolation film, and the gas-permeable isolation film covers the first channel 31C and the second channel 31D. Since the air-permeable isolation membrane only allows air to pass through and prevents liquid water and gaseous water from passing through, it can prevent liquid water or gaseous water from entering the exhaust pipe 35 through the massage cavity 331 .

Embodiment Four

Please refer to FIG. 7 , the difference between the fourth embodiment and the second embodiment is only that the waterproof filter structure 4 is a spring ball structure. Wherein, the spring ball structure can make the first channel 31C conduction when the negative pressure source 34 works and the switch valve 39 is closed, thereby making the communication channel 31B conduction; and when the negative pressure source 34 stops working or breaks the negative pressure of the massage chamber 331 In this state, the conduction of the first channel 31C can be blocked, thereby blocking the communication channel 31B. Such arrangement can also effectively prevent external liquid water or gaseous water from entering the housing 1 through the adsorption port 333 , the massage chamber 331 , the through hole 335 , the communication channel 31B, the exhaust pipe 35 and the negative pressure source 34 in sequence.

Specifically, the spring ball structure includes a ball 47 and a spring 49, the ball 47 is disposed in the first channel 31C and can slide along the first channel 31C, and the spring 49 is inserted into the second channel 31D. When the switch valve 39 is closed and the negative pressure source 34 is working, the ball 47 slides toward the second channel 31D under the negative pressure of the negative pressure source 34 to make the first channel 31C conduct and the spring 49 elastically deforms. Wherein, since the first passage 31C is connected, the negative pressure source 34 can suck the air in the massage chamber 331 through the air suction pipe 35, the communication passage 31B and the through hole 335 in order to make the suction port 333 generate negative pressure and absorb the massage of the human body. parts of the skin. When the on-off valve 39 is opened and the negative pressure source 34 works, since the outside air enters the second channel 31D through the intake pipe 37 and the exhaust pipe 35 successively, the sphere 47 will lose the negative pressure acting on it, and the spring 49 will deform under its own force. The lower recovery elastically deforms so that the ball 47 slides away from the second channel 31D to a position blocking the first channel 31C, thereby blocking the communicating channel 31B. Wherein, during the recovery deformation process of the spring 49 (or in other words, the ball 47 slides away from the second channel 31D to the position before blocking the first channel 31C), the first channel 31C is still conducting, and the water entering the second channel 31D The outside air also enters the massage cavity 331 of the flexible body 33 through the first channel 31C and the through hole 335 in order to break the negative pressure state of the massage cavity 331, that is, when the negative pressure state of the massage cavity 331 is broken, the spring ball structure can block the first One channel 31C is turned on. When the negative pressure source 34 stops working, the ball 47 loses the negative pressure acting on it. At this time, the ball 47 is in the position of blocking the first channel 31C, that is, the spring ball structure blocks the communicating channel 31B.
