[ detailed description ] embodiments

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example one

Referring to fig. 1 and 2, the negative pressure massage apparatus includes a housing 1 and a negative pressure generator 3, the negative pressure generator 3 is installed in the housing 1, and an absorption 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 tube 35.

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

The flexible body 33 is accommodated in the accommodating chamber 31A, the flexible body 33 has a massage chamber 331, and an adsorption port 333 and a through hole 335 provided in the massage chamber 331, and the through hole 335 communicates with the communication passage 31B. Wherein, the flexible body 33 is made of flexible material which can generate elastic deformation, and the absorption port 333 is used for being placed at the parts (such as the back of the hand and the back) of the human body which need massage.

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

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

When the massage device is used, the adsorption port 333 is placed at the part of the human body (such as the back of the hand and the back) needing to be massaged, the negative pressure source 34 works and sequentially pumps the air in the massage cavity 331 through the air pumping pipe 35, the communication channel 31B and the through hole 335 to enable the adsorption port 333 to generate negative pressure to adsorb the skin of the part needing to be massaged, so that the massage effect can be achieved, and meanwhile, the flexible body 33 can deform under the action of the negative pressure to extrude the skin of the part needing to be massaged, so that the kneading massage effect can be achieved.

In this embodiment, the negative pressure source 34 is an air pump, and the air pump 34 has an air pumping port 341 communicating with the air pumping pipe 35 and an air discharging port 343 communicating with the outside.

In this embodiment, the negative pressure generator 3 further includes an air inlet pipe 37 and a switch valve 39, one end of the air inlet pipe 37 is communicated with the massage chamber 331, the other end thereof is communicated with the outside, and the switch valve 39 is provided on the air inlet pipe 37. The switching valve 39 may be an electromagnetic switching valve.

As shown in the figure, the air intake pipe 37 communicates with the air suction pipe 35 so that the air intake pipe 37 communicates with the massage chamber 331 sequentially through the air suction pipe 35, the communication passage 31B, and the through hole 335. That is, the air inlet pipe 37 is indirectly communicated with the massage chamber 331.

During the operation of the negative pressure source 34 of the negative pressure massager, the suction port 333 can periodically generate negative pressure through the opening and closing of the switch valve 39, so that the suction port 333 can continuously suck and relax the skin of the massage part of the human body. Specifically, during the operation of the negative pressure source 34, the negative pressure source 34 sucks the air in the massage cavity 331 through the suction pipe 35, the communication passage 31B and the through hole 335 in sequence to make the suction port 333 generate negative pressure to suck the skin of the human body massage part, meanwhile, during the operation of the negative pressure source 34, the switch valve 39 is periodically opened and closed, the external air enters the massage cavity 331 of the flexible body 33 through the air inlet pipe 37, the suction pipe 35, the communication passage 31B and the through hole 335 in sequence when the switch valve 39 is opened to break the negative pressure state of the massage cavity 331, and when the negative pressure state of the massage cavity 331 is broken, the suction port 333 relaxes the sucked skin of the human body massage part; thereafter, the on-off valve 39 is closed to prevent the external air from entering the massage chamber 331 of the flexible body 33, so that the massage chamber 331 is re-pressurized. That is, the suction or relaxation of the massage part of the human body by the massage chamber 331 is regulated by the periodical opening and closing of the on-off valve 39 of the negative pressure source 34, thereby achieving the massage effect of suction relaxation.

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

Example two

Referring to fig. 3 to fig. 5, the difference between the second embodiment and the first embodiment is only: the first shell 31 includes a shell main body 311 enclosing to form the accommodating cavity 31A and a gland 313 fixedly arranged on one side of the shell main body 311 departing from the accommodating cavity 31A, the communicating channel 31B includes a first channel 31C penetrating through the shell main body 311 and communicating with the through hole 335 and a second channel 31D arranged on the gland 313 and communicating with the first channel 31C and the exhaust tube 35, and the waterproof filter structure 4 arranged on the communicating channel 31B is clamped between the shell main body 311 and the gland 313.

In the present embodiment, the gland 313 is fixed to the case main body 311 by a fastener (e.g., a screw or bolt).

In this embodiment, the waterproof filter structure 4 is an elastic membrane. Wherein the elastic membrane can communicate the first channel 31C and the second channel 31D when the negative pressure source 34 is operated and the switch valve 39 is closed, thereby making the communication channel 31B conductive; and the communication between the first passage 31C and the second passage 31D is blocked when the negative pressure source 34 stops operating or the negative pressure state of the massage chamber 331 is broken, thereby blocking the communication passage 31B. With such an arrangement, external liquid water or gaseous water can be effectively prevented from sequentially entering the housing 1 through the adsorption port 333, the massage cavity 331, the through hole 335, the communication passage 31B, the suction pipe 35 and the negative pressure source 34.

Specifically, the elastic membrane includes a blocking portion 41, a fixing portion 43 provided around the blocking portion 41 and interposed between the case main body 311 and the pressing cover 313, and a plurality of elastic connecting portions 45 provided at intervals and connecting the blocking portion 41 and the fixing portion 43. When the on-off valve 39 is closed and the negative pressure source 34 is operated, the blocking portion 41 moves into the second passage 31D by the negative pressure generated by the negative pressure source 34 to cause the first passage 31C and the second passage 31D to communicate with each other and the elastic connecting portion 45 to elastically deform. Since the first passage 31C and the second passage 31D are communicated with each other, the negative pressure source 34 can suck the air in the massage chamber 331 through the suction pipe 35, the communication passage 31B and the through hole 335 in order to generate the negative pressure at the suction port 333 to suck the skin of the massage part of the human body. When the on-off valve 39 is opened and the negative pressure source 34 is operated, since the external air sequentially enters the second passage 31D through the air inlet pipe 37 and the air exhaust pipe 35 to cause the blocking portion 41 to lose the negative pressure acting thereon, at this time, the elastic connecting portion 45 recovers the elastic deformation under the self deformation acting force to move the blocking portion 41 to the first passage 31C to the position covering the first passage 31C, thereby blocking the communication between the first passage 31C and the second passage 31D. In the process of restoring the deformation of the elastic connection portion 45 (or before the blocking portion 41 moves to the position where the first channel 31C covers the first channel 31C), the first channel 31C and the second channel 31D are still communicated, and the external air entering the second channel 31D further sequentially enters the massage cavity 331 of the flexible body 33 through the first channel 31C and the through hole 335 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 can block the communication between the first channel 31C and the second channel 31D. When the negative pressure source 34 stops operating, the blocking portion 41 loses the negative pressure acting thereon, and at this time, the blocking portion 41 is in a position covering the first passage 31C, that is, the elastic mold blocks the communication between the first passage 31C and the second passage 31D.

In this embodiment, the housing 1 is provided with an air hole 13, and the exhaust port 343 communicates with the air hole 13 through the exhaust pipe 15. The arrangement enables the negative pressure source 34 to exhaust air to the outside through the air hole 13, and when external liquid water or gaseous water enters the negative pressure source 34 through the adsorption port 333, the massage cavity 331, the through hole 335, the communication channel 31B and the exhaust tube 35 in sequence, the negative pressure source 34 can also discharge liquid out of the casing 1 through the exhaust tube 15 and the air hole 13, so as to further avoid short circuit caused by the liquid entering a circuit in the casing 1.

EXAMPLE III

Referring to fig. 6, the difference between the third embodiment and the second embodiment is only: the waterproof filtering structure 4 is a breathable isolation film covering the first channel 31C and the second channel 31D. Since the air-permeable isolating membrane can only allow air to pass through and prevent liquid water and gaseous water from passing through, the liquid water or gaseous water can be prevented from entering the suction pipe 35 through the massage cavity 331.

Example four

Referring to fig. 7, the difference between the fourth embodiment and the second embodiment is only that: the waterproof filtering structure 4 is a spring ball structure. Wherein, the spring ball structure can lead the first channel 31C to be conducted when the negative pressure source 34 works and the switch valve 39 is closed, thereby leading the communication channel 31B to be conducted; and the first passage 31C is blocked from being conducted when the negative pressure source 34 stops operating or the negative pressure state of the massage chamber 331 is broken, thereby blocking the communicating passage 31B. With such an arrangement, external liquid water or gaseous water can be effectively prevented from sequentially entering the casing 1 through the adsorption port 333, the massage cavity 331, the through hole 335, the communication channel 31B, the suction pipe 35 and the negative pressure source 34.

Specifically, the spring ball structure includes a ball 47 and a spring 49, the ball 47 is provided in the first passage 31C and is slidable along the first passage 31C, and the spring 49 is inserted into the second passage 31D. When the on-off valve 39 is closed and the negative pressure source 34 is operated, the ball 47 slides toward the second passage 31D under the negative pressure of the negative pressure source 34 to make the first passage 31C conductive and the spring 49 elastically deforms. Since the first passage 31C is open, the negative pressure source 34 can suck the air in the massage chamber 331 through the suction pipe 35, the communication passage 31B, and the through hole 335 in order to generate the negative pressure at the suction port 333 to suck the skin of the massage area of the human body. When the on-off valve 39 is opened and the negative pressure source 34 is operated, since the external air sequentially enters the second passage 31D through the air inlet pipe 37 and the air exhaust pipe 35 to cause the ball 47 to lose the negative pressure acting thereon, the spring 49 restores the elastic deformation under its own deformation acting force to make the ball 47 slide to a position away from the second passage 31D to block the first passage 31C, thereby blocking the communicating passage 31B. In the process of restoring the deformation of the spring 49 (or before the ball 47 slides away from the second channel 31D to the position blocking the first channel 31C), the first channel 31C is still conducted, and the external air entering the second channel 31D sequentially enters the massage cavity 331 of the flexible body 33 through the first channel 31C and the through hole 335 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 conduction of the first channel 31C. When the negative pressure source 34 stops operating, the ball 47 loses the negative pressure acting thereon, and at this time, the ball 47 is in a position of blocking the first passage 31C, i.e., the spring-ball structure blocks the communication passage 31B.

That is to say, the end of the second air tube 353 is connected with a plurality of adsorption units formed by combining the first shell 31 and the flexible body 33, so that the user can conveniently select one or more adsorption units (meeting the requirements of the user on different massage parts) to massage the human body part, and the structure is simple and the use is convenient.

In this embodiment, at least two branch air pipes 355 communicate with the collecting air pipe 357 through the adapter 7. In other embodiments, the adapter 7 may have a switch structure built therein, so that a user can open or close the different branch air pipes 355 conveniently, thereby controlling the opening or closing of the different adsorption units.

That is, the second housing 5 in the present embodiment has the same structure as the first housing 31 in the second to fourth embodiments.

It should be noted that, since the flexible body 33 and the first housing 31 in the first to fourth embodiments are detachably connected, and the connector 6 and the second housing 5 in the fifth embodiment are detachably connected, the user can change the negative pressure massage apparatus in the first to fourth embodiments to the negative pressure massage apparatus in the fifth embodiment or change the negative pressure massage apparatus in the fifth embodiment to the negative pressure massage apparatus in the first to fourth embodiments by replacing the components.

It should be noted that, in the negative pressure massage device of the fifth embodiment, the second air tube 353 of the negative pressure massage device may be configured as a tube body having only two ports, one port of the second air tube 353 is communicated with the communicating channel 31B, and the other port thereof is communicated with the air guide cavity 61 of the connecting head 6.
