DETAILED DESCRIPTION

(11) In order to make the objectives, technical solutions and advantages of the present disclosure clear, the following further describes the present disclosure in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure, but not to limit the present disclosure.

(12) The first embodiment of the air pressure massager of the present disclosure will be illustrated with reference to FIGS. 1-3. FIG. 1 is a n exploded view of a first embodiment of an air pressure massager of the present disclosure. FIG. 2 is a cross-sectional view of the first embodiment of the air pressure massager of the present disclosure. FIG. 3 is a cross-sectional view of the first embodiment of the air pressure massager of the present disclosure.

(13) The first embodiment of the air pressure massager 1 is optionally, a portable electrical device or a small device, which comprises a housing 8, a pressure field generating device 2, and a switch 72.

(14) Optionally, the switch 72 is configured to turn on and turn off the air pressure massager 1. The switch 72 may be, for example, a button controlled to turn on or off the air pressure massager 1, or a lock sliding switch. Alternatively, it is possible to turn on and turn off the air pressure massager 1 by remote control.

(15) The pressure field generating device of the first embodiment comprises a chamber 3 of the air pressure massager. The chamber 3 comprises at least one first opening 31 configured to be placed on a portion of a human body 11, a connecting rod member 5 connected to one end of the chamber 3, an eccentric member 4 connected to the connecting rod member 5, a driving unit 6 in a transmission connection with the eccentric member 4, a control device configured to activate the drive unit 7, and an accessory 18. The driving unit 6 drives the eccentric member 4 to move to drive the connecting rod member 5 to move, such that a volume of the chamber is changed to generate a pressure field for stimulating the human body. The pressure field generated in the chamber 3 directly towards the portion of the human body. The pressure field is adjusted by a positive pressure mode and/or a negative pressure mode.

(16) For example, the driving unit 6 may be an electric motor, and the driving unit 6 drives the chamber 3 through an output shaft of the driving unit 6 and by means of the eccentric member (or alternatively by means of the connecting rod member), so that the volume of the chamber 3 changes along with rotation of the output shaft of the driving unit 6. However, it should be noted that, in principle, any type of driving device that causes a wall 9 of the chamber 3 to deform for volume changes can be used in the air pressure massager 1. The driving device can, for example, be performed hydraulically, pneumatically, mechanically or electromagnetically. An example is described in detail below.

(17) The control device turns on the driving unit 6, and the driving unit 6 drives the eccentric member 4 to move to drive the connecting rod member 5 to move, such that a volume of the chamber 3 is changed to generate a pressure field for stimulating the human body. There is no gap between the chamber 3 and the connecting rod member, which is convenient for cleaning and maintenance, and solves the hygiene problem. The single chamber 3 ensures an integrity of the structure, thereby improving an overall waterproof performance. The pressure field generated by the single chamber 3 is configured to directly act on the human body, and there is no intermediate conduction energy loss, such that an excellent experience is obtained.

(18) Furthermore, the air pressure massager 1 further comprises the housing 8. The housing 8 comprises a second opening 83. A main body of the chamber 3 extends into the housing 8 through the second opening 83 of the housing 8. Optionally, a design of the housing 8 conforms to an ergonomic form, so that the housing 8 can be comfortably held by one hand and has no sharp edges or sharp edges.

(19) The air pressure massager 1 further comprises the accessory 18. Optionally, the accessory 18 is a portion of the housing 8 and is able to be moved relative to the housing 8 accommodating the pressure field generating device 2.

(20) Furthermore, the chamber 3 may be made of a soft rubber material, such as a silicone material. For example, the chamber 3 is made of silicone film that made of the silicone material, which is convenient for contacting the skin area of the human body to be stimulated. The rotation of the eccentric member 4 drives the connecting rod member 5 to pull the silicone film, so that the volume of the chamber 3 made by the silicone film changes, and a movement stroke is 5 mm, thereby generating a pressure field for stimulation, which has a good stimulation effect and is convenient to use.

(21) Further, a size of the first opening 31 is 12.5 mm, which is reasonable in size and fits and stimulates the human body well.

(22) The structure and function of a first aspect of the pressure field generating device 2 of the air pressure massager 1 will be described in detail below with reference to FIGS. 5-7. FIG. 5 is a cross-sectional view of a pressure field generating device where the air pressure massager of the present disclosure is in a first state. FIG. 6 is a cross-sectional view of the pressure field generating device where the air pressure massager of the present disclosure is in a second state. FIG. 7 is a cross-sectional view of the pressure field generating device where the air pressure massager of the present disclosure is in a third state.

(23) FIG. 5 shows the pressure field generating device 2 in the first state, in which the chamber 3 is placed on the skin area or the portion of the human body 11 to be stimulated. The first state of the pressure field generating device 2 is demonstrated by a neutral deformation of the chamber 3.

(24) The portion of the human body 11 to be stimulated is an area of the skin on the body. In the embodiment, the portion of the human body 11 is the clitoris 12, which is particularly sensitive. However, the use of the present disclosure is not limited to the clitoris 12. On the contrary, the air pressure massager 1 can be applied to any portion of the human body 11 or erogenous zones (such as inner thigh, waist area, nape, nipples, etc.) that can be stimulated by means of medium, air-pressure massage and/or negative pressure.

(25) Since the chamber 3 is placed on the portion of the human body 11 to be stimulated, the chamber 3 is, to a large extent or completely isolated from an outside of the pressure field generating device 2. That is, the pressure field generating device 2 is connected with the chamber 3 through connecting rod member, in which an edge of the chamber 3 and a surface of the portion of the human body 11 ideally form an air-tight enclosure.

(26) FIG. 6 shows the pressure field generating device 2 in the second state, in which the chamber 3 is placed on the skin area or the portion of the human body 11 to be stimulated. When in the second state, a force A acting on the chamber 3 causes the volume of the chamber 3 to decrease or compress. To be specific, a direction of force A is opposite to a direction of force B and the force A deforms the wall 9 of the chamber 3, so that the resulting volume V3 of the chamber 3 is smaller than the volume V1 (V1 is the volume of the chamber 3 where the pressure generating device is in the first state). The compression of the chamber 3 results in a positive pressure in the chamber 3.

(27) The flow of the medium is limited by the first opening 31 and is now directed towards the portion of the human body 11 to be stimulated, in particular towards the clitoris glans of the clitoris 12. The indirect (pressure) massage occurs due to the flow of the medium onto the portion of the human body 11. In this embodiment, the size of the first opening 31 is set to be sufficiently small relative to the change of the volume in the chamber 3, so that the medium is sufficiently accelerated for a noticeable massage effect.

(28) Furthermore, this type of medium is not only affected by the size and orientation of the first opening 31 but also affected by the connecting rod member 5. For example, the movement of the connecting rod member 5 makes the medium to rotate, so that the medium is distributed on the portion of the human body 11 to be stimulated to produce a softer or more turbulent effect.

(29) FIG. 7 shows the pressure field generating device 2 in the third state, in which the chamber 3 is placed on the skin area or the portion of the human body 11 to be stimulated. When in the third state, the force B acting on the chamber 3 makes the volume of the chamber 3 to expand. To be specific, the force B pulls the wall 9 of the chamber 3 along a direction away from the chamber 3, which increases the volume of the chamber 3, so that the resulting volume V2 of the chamber 3 is greater than the volume V1. that is, V2>V1. The compression of the chamber 3 results in a positive pressure in the chamber 3. In order to equalize the pressure difference formed between the chamber 3 and the medium/air, the medium/air flows into a lower end of the chamber 3.

(30) Assuming that in the first state, the pressure in the chamber 3 corresponds to the current external reference pressure (for example, air pressure), an overall pressure in the chamber is lower than the external reference pressure in the second state. The negative pressure is set to be lower than the normal systolic pressure in the blood vessels of the portion of the human body 11. The blood circulation in this area is therefore increased. In the embodiment, the clitoris 12 is better supplied with blood in the second state.

(31) The pressure generating device 2 shown in FIGS. 5-7 has advantages that it is easy to clean from a hygienic point of view (because dead space is avoided) and simple to manufacture. For example, there is no need to disposed any valve or any other openings on the chamber 3.
