Description

Technical Field

[0001] The present invention relates to a skin suction head used for, for example, treatment, beauty, or massage, and a suction device including the same.

Background Art

[0002] Devices that press a suction head against the skin and perform treatment or massage while sucking the skin are known. For example, the massager described in Patent Document 1 includes a cup support tool that supports two cups (suction / discharge tools) and a main body that incorporates a pump. A tube is interposed between the main body and the cup support tool. One end of the tube is connected to the pump of the main body, and the other end is branched into two and connected to the cups provided in the cup support tool, respectively.

[0003] Since this massager includes two cups, for example, the two cups can be simultaneously abutted against two acupoints on the neck muscles, and an excellent massage effect can be obtained. In addition, since the distance between the two cups of this massager can be changed, the distance can be adjusted to a distance according to individual differences and the target site.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In the massager described in Patent Document 1, the mechanism for adjusting the distance between the two cups was to loosen the wing nuts corresponding to each of the two cups and move the screws attached to each wing nut along the long holes. In this configuration, in order to change the distance between the two cups, it was necessary to loosen the two wing nuts and then move each of the two cups individually.

[0006] The present invention aims to solve the aforementioned conventional problems and to provide a skin suction head and a suction device equipped therewith that can change the distance between two suction tubes with simple operation. [Means for solving the problem]

[0007] To achieve the above objective, the present invention provides a skin suction head for suctioning skin, comprising: a main body case; a movable case; a first suction tube integrated with the main body case; a second suction tube integrated with the movable case; a slide tube connecting the main body case and the movable case; and a rotating ring housed in the main body case, the inner circumference of which is screwed onto the slide tube. The slide tube is fixed at one end to the movable case and slidably inserted at the other end into a lateral hole provided in the main body case. By rotating the rotating ring screwed onto the slide tube, the amount the slide tube enters the lateral hole changes, causing the movable case to move in the axial direction of the slide tube. The second suction tube, integrated with the movable case, moves in conjunction with the movement of the slide tube, thereby changing the distance between the first suction tube and the second suction tube.

[0008] The suction device of the present invention is a suction device equipped with the skin suction head of the present invention, comprising a suction hose connected to the skin suction head and an operating panel connected to the suction hose. [Effects of the Invention]

[0009] The skin suction head of the present invention is equipped with two suction tubes, so for the same area, suction can be performed faster compared to a configuration with one suction tube, and since suction is performed with both suction tubes simultaneously, the stimulating effect is also enhanced. Furthermore, the distance between the two suction tubes can be adjusted, allowing the distance to be set to a dimension that suits individual differences and the target area, and this adjustment can be performed with a simple operation of just rotating a single rotating ring.

[0011] Hereinafter, one embodiment of the present invention will be described with reference to the drawings. First, an overview of the suction device 1 according to one embodiment of the present invention will be described with reference to Figure 1. Figure 1 is an overall perspective view of the suction device 1 according to this embodiment. A suction hose 3 is connected to the control panel 2, and a skin suction head 20 is connected to the tip of the suction hose 3. A power cord 4 is connected to the control panel 2, and the operation and stopping of the suction device 1 are switched on and off by the ON / OFF of the power switch 5. An electric pump (not shown) is built into the suction device 1, and when the electric pump is driven, air is sucked in from the suction ports 22a and 22b (see Figure 2) at the tips of the suction tubes 21a and 21b provided on the skin suction head 20, and exhausted through the suction hose 3.

[0012] By the suction mode selection buttons 6 - 8, the suction force can be switched to three levels of low, medium, and high suction modes. In each suction mode, the suction force can be further adjusted by adjusting the suction adjustment dial 9. The suction force is displayed on the suction force display panel 10. Also, by pressing the suction force reset button 11, the suction force can be reset.

[0013] The suction device 1 has a timer function. The set time can be lengthened by the time - up button 12 and shortened by the time - down button 13. The set time of the timer is displayed on the timer display panel 14.

[0014] Figure 2 shows an overall perspective view of the skin suction head 20 shown in Figure 1. The skin suction head 20 mainly consists of a main body case 23 and a movable case 24. A suction pipe 21a having a suction port 22a is attached to the main body case 23. A suction pipe 21b having a suction port 22b is attached to the movable case 24, and a connection pipe 25 for connecting the suction hose 3 (Figure 1) is provided. An O - ring 26 for sealing is attached to the connection pipe 25.

[0015] A slit 28 is formed in the main body case 23, and a rotating ring 29 is arranged inside the slit 28 (see Figure 4). When the rotating ring 29 is manually rotated, the movable case 24 moves. The moving direction of the movable case 24 is the direction in which the distance between the suction pipes 21a and 21b arranged in parallel changes (direction of arrow A). The adjustment of the distance between the suction pipes 21a and 21b by the operation of the rotating ring 29 will be described later.

[0016] Figure 3 is a perspective view of the skin suction head 20 seen from the side of the connection pipe 25. A suction port 27 for sucking air into the suction hose 3 (Figure 1) is formed in the connection pipe 25. A gap B is formed between the main body case 23 and the movable case 24. The gap B changes by the rotational operation of the rotating ring 29, and at the same time, the distance between the suction pipes 21a and 21b changes.

[0017] Figure 4 is an exploded perspective view of the skin suction head 20. The slide tube 30 is shown in a state removed from the movable case 24. In the assembled state of the skin suction head 20, the screw 36 is screwed into the screw hole 34 formed in the slide tube 30. O-rings 32 and 33 for sealing are attached to the slide tube 30.

[0018] The rotating ring 29 is shown in a state removed from the slide tube 30. In the assembled state of the skin suction head 20, the female screw 29a provided on the rotating ring 29 and the male screw 31 provided on the slide tube 30 are screwed together.

[0019] Figure 5 shows a state where the slide tube 30 is attached to the movable case 24 and the rotating ring 29 is housed in the main body case 23 from the state of Figure 4. The rotating ring 29 is inserted into the main body case 23 through the slit 28 of the main body case 23. From the state of Figure 5, when the tip of the slide tube 30 is pushed into the horizontal hole 40 provided in the main body case 23 and the female screw 29a provided on the rotating ring 29 and the male screw 31 provided on the slide tube 30 are screwed together, the skin suction head 20 is in an assembled state.

[0020] Hereinafter, the adjustment of the distance between the suction tubes 21a and 21b by operating the rotating ring 29 will be described. Figure 6 shows a front view of the skin suction head 20 as viewed from the side of the suction tubes 21a and 21b. A part of the main body case 23 is broken to illustrate the internal structure. The internal structure shown is only the main part for the sake of illustration convenience.

[0021] Figure 6 shows a state where the distance (distance between the center points) between the suction tubes 21a and 21b is the maximum value D1. In this state, a gap B is formed between the main body case 23 and the movable case 24. Also, at the end of the male screw 31 provided on the slide tube 30, the female screw 29a (see Figure 4) of the rotating ring 29 is screwed.

[0022] Figure 7 shows a horizontal cross-sectional view of the skin suction head 20 in the state shown in Figure 6. Figure 7 shows the suction hose 3 (see Figure 1) connected to the connecting tube 25. The connection structure between the connecting tube 25 and the suction hose 3 is simplified in the illustration. Also, as in Figure 6, a gap B is formed between the main body case 23 and the movable case 24, and the distance between the suction tubes 21a and 21b is the maximum value D1.

[0023] In Figure 7, when the skin suction head 20 is in use, the electric pump built into the suction device 1 (see Figure 1) drives air from the suction ports 22a and 22b at the tips of the suction tubes 21a and 21b (arrows a and b), and exhausts it through the suction hose 3 (arrow h).

[0024] More specifically, the air flowing into the suction tube 21b (arrow a) passes through the slide tube 30 via the hole 35 provided in the slide tube 30, flows into the connecting tube 25, and is exhausted into the suction hose 3 (arrows c, g, h). The air flowing into the suction tube 21a (arrow b) passes through the slide tube 30 via the hole 41 provided in the main body case 23, passes through the slide tube 30 via the hole 35 provided in the slide tube 30 (arrows d, e, f, g). After that, it flows into the connecting tube 25 and is exhausted into the suction hose 3 (arrow h).

[0025] As shown in Figure 2, the rotating ring 29 is positioned between slits 28 provided in the main body case 23 in the thickness direction. Furthermore, as shown in Figure 7, the slits 28 continue into the interior of the main body case 23. Therefore, the rotating ring 29 is also positioned between the slits 28 inside the main body case 23. In this configuration, the positional movement of the rotating ring 29 in the width direction of the slits 28 (axial direction of the slide tube 30) is restricted.

[0026] As described above, in Figure 6, the female thread 29a (see Figure 4) of the rotating ring 29 is screwed into the end of the male thread 31 provided on the slide tube 30. In this embodiment, the male thread 31 and the female thread 29a are formed such that, when the rotating ring 29 is viewed from the side of the main body case 23, and the rotating ring 29 is not housed in the main body case 22 as shown in Figure 6, the rotating ring 29 moves toward the movable case 23 when the rotating ring 29 is rotated clockwise.

[0027] On the other hand, as described above, the axial movement of the rotating ring 29 relative to the slide tube 30 is restricted. Therefore, even if the rotating ring 29 is rotated clockwise, the position of the rotating ring 29 does not change, but as the rotating ring 29 rotates, the movable case 24 fixed to the slide tube 30 is pulled towards the main body case 23. In other words, the amount the slide tube 30 enters the lateral hole 40 increases. As a result, the gap B between the main body case 23 and the movable case 24 becomes smaller, and the distance D1 between the suction tubes 21a and suction tubes 21b also becomes smaller.

[0028] Figure 8 shows the state where the distance (center-to-center distance) between suction tubes 21a and 21b changes from the maximum value D1 to the minimum value D2. In this state, there is no gap between the main body case 23 and the movable case 24 (arrow E). In this figure, the suction tube 21b in the state shown in Figure 6 is indicated by a dashed line.

[0029] Figure 9 shows a horizontal cross-sectional view of the skin suction head 20 in the state shown in Figure 8. Except that the distance between the suction tubes 21a and 21b is at its minimum value D2, the configuration is the same as in Figure 7, and the suction flow is also the same as in Figure 7.

[0030] From the state shown in Figure 8, rotating the rotating ring 29 in the opposite direction to the state from Figure 6 to Figure 8 increases the minimum value D2 interval up to the maximum value D1, returning to the state shown in Figure 6. Therefore, according to the skin suction head 20 of this embodiment, it is possible to adjust the distance between the suction tubes 21a and 21b between the maximum value D1 and the minimum value D2 by simply rotating one rotating ring 29. In other words, in this embodiment, it is not necessary to adjust the position of the suction tubes 21a and 21b individually. The maximum value D1 is, for example, 31 mm, and the minimum value D2 is, for example, 23 mm.

[0031] Figure 10 is a perspective view showing the skin 50 being suctioned by the skin suction head 20. In the state shown in Figure 10, the suction tubes 21a and 21b are in contact with the skin 50. In this state, when the skin suction head 20 is moved along the skin 50 (arrow F), a wide area of ​​the skin 50 can be suctioned. Since the skin suction head 20 is equipped with two suction tubes 21a and 21b, suction can be achieved faster over the same area compared to a configuration with one suction tube, and the stimulating effect is also enhanced because suction is performed by both suction tubes simultaneously.

[0032] Furthermore, by adjusting the distance between the suction tubes 21a and 21b, it becomes possible to adjust the distance to a dimension that suits individual differences and the target area. As mentioned above, this adjustment can be done with a simple operation of just rotating one rotating ring 29.

[0033] There are no particular restrictions on the area where the skin suction head 20 can be used, but the neck is one example. The cervical vertebrae in the neck have multiple muscles running vertically, and using the skin suction head 20 allows for simultaneous stimulation of multiple muscles. The position of the muscles varies from person to person, but as mentioned above, the distance between the suction tubes 21a and 21b can be easily adjusted, so it is possible to adjust the distance to suit the individual in a short amount of time.

[0034] Although one embodiment of the present invention has been described above, the above embodiment is merely an example and may be modified as appropriate. For example, the screw threads of the screw portion of the rotating ring 29 that widens (narrows) the gap between the suction tubes 21a and 21b may be formed so that the direction of rotation is opposite to that of the above embodiment.
