Description

Air massage device with forced exhaust

[0001] The present invention relates to an air massage device, and more particularly, to an air massage device capable of forced exhaust.

[0002] In general, modern society has led a convenient life based on many benefits of civilization, and as we live without knowing the inconveniences of life, such as cars, buses, and trains that allow us to quickly travel short and long distances, and department stores, markets, and various entertainment facilities are built in urban areas, our eating habits are gradually becoming more affluent and westernized, and obesity is gradually increasing due to excessive nutritional intake and lack of exercise.

[0003] In addition, the environmental pollution that appears from the advantages of this civilization, the lack of time due to social life, and the stress that arises from this overlap and act as causes of various diseases.

[0004] In order to eliminate the causes of these various diseases, the best way is to breathe clean air, get enough rest, and exercise appropriately. However, as these conditions are not sufficient, various exercise aids and massagers have emerged as alternatives.

[0005] Massagers are available in mechanical force and air pressure massagers. Air massagers using air pressure are generally configured to include a pressurized unit having a pump as a means for pressurizing external air and a filtering unit for filtering out foreign substances, a control unit for distributing and supplying air from the pressurized unit according to pressure or sequence, and a pressurized air pad for storing or discharging the pressurized air from the control unit.

[0006] The above pressurized air pad is made of an inner and outer layer and is sewn so that it can be inserted or wrapped around a part of the body, and is designed to be inflated when air is supplied to the pressure applied from the outside through the injection port.

[0007] The above inner skin is also flat and has a Javara shape to increase the cross-sectional area and increase the efficiency of the massager.

[0008] An air massager using air pressure configured as above is operated by placing an air pad on the user's leg or arm, etc., and connecting the inlet and the control unit with a hose. When the air pad is operated, the outside air is compressed by the pump, and as the compressed air is alternately and repeatedly injected through the hose and the inlet under the control of the control unit, the inner lining of the air pad expands, and the pressure presses a part of the body, thereby achieving the effect of the massager.

[0009] However, the above-mentioned air massager is generally equipped with multiple air pads to evenly massage the body. However, when air is injected into multiple air pads using a single pump and the air is exhausted from some of the air pads, there is a problem in that the air pressure of other air pads is unintentionally reduced as the air injected through the pump is also exhausted. In addition, there is also the problem of difficulty in forcibly exhausting the air inside each air pad.

[0010] In other words, even if air is injected into multiple air pads using a single pump, it is necessary to develop an air massager that can independently inject air, maintain air pressure, and discharge air for each air pad, and can forcibly exhaust the air inside each air pad.

[0011] (Patent Document 1) Japanese Patent Application Publication No. 2021-016409 (published on February 15, 2021)

[0012] The present invention is intended to solve the above problems, and the purpose of the present invention is to provide an air massage device capable of independently injecting air, maintaining air pressure, and exhausting air for each air pad even when air is injected into a plurality of air pads using a single pump, and capable of forced exhaust to forcibly exhaust the air inside each air pad.

[0027] At this time, the control unit can control the operation of the second common valve member so that the fluid communication between the main supply pipe and the suction pipe is blocked when the air inside the air cell is forcibly discharged.

[0028] At this time, the control unit can control the operation of each valve member so that when the air inside the air cell is naturally discharged, the air flowing through the air cell pipe is discharged sequentially through the suction pipe and the main supply pipe.

Here, the X direction is a length direction, the Y direction is a width direction, and the Z direction is a height direction. In order to clearly describe the present invention, parts that are not related to the description are omitted from the drawings.

[0052] As illustrated in FIGS. 1 to 4, an air massage device capable of forced exhaust according to one embodiment of the present invention comprises a plurality of air cells (10), a single air pump (20) for supplying or exhausting air to each air cell (10), an intake pipe (30) through which air supplied to the air pump (20) flows, a discharge pipe (40) through which high-pressure air discharged from the air pump (20) flows, a plurality of air cell pipes (50) in fluid communication with each air cell (10), a plurality of first individual valve members (100) for controlling whether or not each air cell pipe (50) is in fluid communication with the discharge pipe (40), a plurality of second individual valve members (200) for controlling whether or not each air cell pipe (50) is in fluid communication with the suction pipe (30), a main supply pipe (60) in fluid communication with the suction pipe (30), a main discharge pipe (70) in fluid communication with the discharge pipe (40), and a discharge pipe (40). It includes a first common valve member (300) that controls whether the main discharge pipe (70) is in fluid communication, a second common valve member (400) that controls whether the suction pipe (30) and the main supply pipe (60) are in fluid communication, and a control unit (500) that controls the operation of the air pump (20) and each valve member.

[0053] For example, these multiple air cells (10) may be provided to enable independent air massage at various locations, such as the foot, lower calf, upper calf, lower thigh, and upper thigh, based on the user's legs. Alternatively, these multiple air cells (10) may be provided to enable independent air massage at various locations, such as the hand, wrist, upper arm, and lower arm, based on the user's arms.

[0054] At this time, air is supplied to the plurality of air cells (10) using an air pump (20). Since air is supplied to the plurality of air cells (10) using a single air pump (20), the size and weight of the entire device are reduced, and the manufacturing cost can be reduced. An intake pipe (30) through which air supplied by the air pump (20) flows, a discharge pipe (40) through which high-pressure air discharged from the air pump (20) flows, a plurality of air cell pipes (50) in fluid communication with each air cell (10), a main supply pipe (60) in fluid communication with the intake pipe (30), and a main discharge pipe (70) in fluid communication with the discharge pipe (40) are provided, thereby not only connecting the plurality of air cells (10) and the single air pump (20), but also connecting the air cells (10) and the outside so that the air inside the air cells (10) is discharged to the outside. A pressure pipe (80) equipped with a pressure sensor can be fluidly connected to the first individual valve member (100).

[0055] In addition, a plurality of first individual valve members (100) for controlling whether each air cell pipe (50) and discharge pipe (40) are in fluid communication, a plurality of second individual valve members (200) for controlling whether each air cell pipe (50) and suction pipe (30) are in fluid communication, a first common valve member (300) for controlling whether the discharge pipe (40) and the main discharge pipe (70) are in fluid communication, and a second common valve member (400) for controlling whether the suction pipe (30) and the main supply pipe (60) are in fluid communication are provided to control the flow of air supplied from the air pump (20) to the air cell (10) or air discharged to the outside from the air cell (10).

[0056] At this time, the control unit (500) controls the operation of the air pump (20) and the operation of each valve member. However, since air is supplied to a plurality of air cells (10) using a single air pump (20) in this way, it is important to configure it so that stable operation is possible without mutual influence even if different operations are performed in each air cell (10), and for this purpose, as described above, a plurality of first individual valve members (100) and a plurality of second individual valve members (200) are provided. That is, since a first individual valve member (100) and a second individual valve member (200) are provided for each air cell (10), even if air is supplied using a single air pump (20), each air cell (10) is able to operate independently and stably without mutual influence.

[0057] In addition, a first common valve member (300) and a second common valve member (400) are provided so that communication between each air cell (10) and the outside can be controlled, thereby forcibly discharging air inside the air cell (10).

[0058] At this time, as shown in Fig. 1, a surge tank (90) can be connected to the main discharge pipe (70), through which the shock action of air that may occur due to sudden shut-off or sudden operation of the air pump (20) or sudden opening and closing of each valve member can be buffered.

[0059] FIG. 5 is a cross-sectional view of part I-I of FIG. 4, FIG. 6 is a cross-sectional view of part II-II of FIG. 4, and is a drawing illustrating a state in which air is injected into an air cell, and FIG. 7 is a cross-sectional view of part I-I of FIG. 4, and is a drawing illustrating a state in which air is injected into an air cell.

[0060] As illustrated in FIG. 5, the first individual valve member (100) is provided with a first delivery passage (110) in which a passage is formed to allow air to flow to the neighboring first individual valve members (100), and a supply passage (120) in which a passage is formed to allow air to flow to the air cell pipe (50).

[0061] That is, the air supplied to the first individual valve member (100) moves to the neighboring first individual valve member (100) through the first transmission path (110) or flows to the air cell pipe (50) through the supply path (120).

[0062] At this time, the control unit (500) can control the operation of the first individual valve member (100) so that air flows to the supply path (120) when air is injected into the air cell (10). That is, as illustrated in FIG. 6, the air supplied to the first individual valve member (100) moves to the air cell (10) through the supply path (120).

[0063] At this time, as illustrated in FIG. 5, a plurality of first individual valve members (100) can be modularly arranged to be mutually connected, and by configuring in this manner, not only can a plurality of first individual valve members (100) be simply assembled into an air massage device, but also fluid communication between the plurality of first individual valve members (100) can be stably maintained.

[0064] As illustrated in FIG. 7, the control unit (500) can control the operation of the first individual valve member (100) so that air flows to the first transmission path (110) when air is injected into neighboring air cells (10).

[0065] That is, the air supplied to the sequentially arranged first individual valve members (100) moves sequentially through the first delivery path (110), and the air moved in this way moves to the air cell pipe (50) through the supply path (120) provided in the first individual valve member (100) arranged in the air cell (10) into which air is to be injected, thereby allowing air to be stably injected into the air cell (10).

[0066] Fig. 8 is a cross-sectional view of part Ⅰ-Ⅰ of Fig. 4, which illustrates a state in which air is injected into one air cell and then into another air cell.

[0067] As illustrated in FIG. 8, the control unit (500) can control the operation of the first individual valve member (100) so that when air is injected into another neighboring air cell (10) after completing the injection of air into one air cell (10), the supply path (120) provided in the first individual valve member (100) connected to one air cell (10) is blocked and the air flows into the supply path (120) provided in the first individual valve member (100) connected to the other air cell (10).

[0068] That is, when air injection into one air cell (10) is completed, the control unit (500) blocks (turns off) the current applied to the first individual valve member (100) connected to one air cell (10), thereby blocking the supply path (120) provided in the first individual valve member (100) connected to one air cell (10), and applies (turns on) current to the first individual valve member (100) connected to another air cell (10), thereby opening the supply path (120) provided in the first individual valve member (100) connected to another air cell (10), thereby controlling air injection into the other air cell (10).

[0069] That is, when air is injected into one air cell (10) and the massage intensity according to the pressure selected by the user is secured, a holding operation is performed in which air is no longer supplied to one air cell (10), and at the same time, air can be injected into another air cell (10).

[0070] Fig. 9 is a cross-sectional view of part Ⅲ-Ⅲ of Fig. 4, and Fig. 10 is a cross-sectional view of part Ⅱ-Ⅱ of Fig. 4, which is a drawing showing a state in which air inside an air cell is discharged.

[0071] As illustrated in FIG. 9, the second individual valve member (200) is provided with a discharge path (210) in which a path is formed so that air inside the air cell (10) discharged through the air cell pipe (50) flows to the suction pipe (30), and as illustrated in FIG. 10, the control unit (500) can control the operation of the second individual valve member (200) so that air flows to the discharge path (210) when the air inside the air cell (10) is discharged.

[0072] That is, when the massage intensity through the air cell (10) is reduced or the massage process is finished, the air inside the air cell (10) is discharged to the outside, and in this case, the control unit (500) controls the operation of the second individual valve member (200) so that the air flows into the discharge path (210) provided in the second individual valve member (200). At this time, the control unit (500) can control the air to flow into the discharge path (210) provided in the second individual valve member (200) by blocking (turning off) the current applied to the second individual valve member (200). With this configuration, the air inside the air cell (10) flowing through the air cell pipe (50) moves to the suction pipe (30) through the discharge path (210) of the second individual valve member (200), so that the air inside the air cell (10) can be discharged to the outside, and since there is no need to apply current to the second individual valve member (200) when discharging the air inside the air cell (10), the current consumption can be minimized.

[0073] At this time, the air that has moved to the suction pipe (30) can be forcibly discharged to the outside through the air pump (20) or naturally discharged through the main supply pipe (60), and the control unit (500) controls the operation of the first common valve member (300), the second common valve member (400), and the operation of the air pump (20) to enable forced or natural exhaust.

[0074] In addition, a plurality of second individual valve members (200) can be modularly arranged to be mutually connected, and the plurality of second individual valve members (200) can be mutually connected through the second transmission path (220). With this configuration, not only can the plurality of second individual valve members (200) be easily assembled into the air massage device, but also the fluid communication between the plurality of second individual valve members (200) can be stably maintained.

[0075] As illustrated in FIG. 6, the control unit (500) can control the operation of the second individual valve member (200) so that air flowing into the air cell pipe (50) when air is injected into the air cell (10) is prevented from being discharged through the second individual valve member (200).

[0076] That is, the control unit (500) controls the operation of the first individual valve member (100) so that air flows to the supply path (120) when air is injected into the air cell (10). At this time, it is important to control so that the air that has moved to the air cell pipe (50) through the first individual valve member (100) is not discharged to the second individual valve member (200) connected to the air cell pipe (50). With this configuration, air can be stably injected into the air cell (10).

[0077] As illustrated in FIG. 5, the first common valve member (300) is provided with a first common delivery path (310) in which a path is formed so that air flowing through the discharge pipe (40) flows to the first individual valve member (100), and a common discharge path (320) in which a path is formed so that air flowing through the discharge pipe (40) flows to the main discharge pipe (70). At this time, as illustrated in FIG. 7, the control unit (500) can control the operation of the first common valve member (300) so that air flows to the first common delivery path (310) when air is injected into the air cell (10).

[0078] That is, the control unit (500) can control the air flowing through the discharge pipe (40) through the first common valve member (300) to flow into the first common transmission path (310), and through this, the air can be stably injected into the air cell (10) while flowing into the first individual valve member (100).

[0079] Fig. 11 is a cross-sectional view of part Ⅰ-Ⅰ of Fig. 4, which is a drawing showing a state in which air injected into an air cell is forcibly exhausted.

[0080] As illustrated in Fig. 11, the control unit (500) can control the operation of the first common valve member (300) so that air flows into the main discharge pipe (70) when forcibly discharging air inside the air cell (10).

[0081] That is, the control unit (500) can control the air flowing into the discharge pipe (40) through the first common valve member (300) to flow into the common discharge path (320), thereby allowing the air to flow into the main discharge pipe (70) and be forcibly discharged to the outside.

[0082] Fig. 12 is a cross-sectional view of part Ⅲ-Ⅲ of Fig. 4, which illustrates a state in which external air is introduced into an air pump through a suction pipe, and Fig. 13 is a cross-sectional view of part Ⅲ-Ⅲ of Fig. 4, which illustrates a state in which air injected into each air cell is naturally exhausted.

[0083] As shown in FIGS. 12 and 13, the second common valve member (400) is provided with a common supply passage (410) in which a passage is formed so that the main supply pipe (60) and the suction pipe (30) are in fluid communication, and the control unit (500) can control the operation of the second common valve member (400) so that the main supply pipe (60) and the suction pipe (30) are in fluid communication when air is injected into the air cell (10) or when air inside the air cell (10) is naturally discharged.

[0084] That is, as shown in Fig. 12, when air is injected into the air cell (10), the common supply path (410) provided in the second common valve member (400) is opened so that external air is introduced into the air pump (20), and the external air moves sequentially through the main supply pipe (60) and the suction pipe (30).

[0085] In addition, as illustrated in FIG. 13, even when the air inside the air cell (10) is naturally discharged, the common supply path (410) provided in the second common valve member (400) is opened so that the air inside the air cell (10) can be naturally discharged to the outside while sequentially passing through the suction pipe (30) and the main supply pipe (60).

[0086] Fig. 14 is a cross-sectional view of part IV-IV of Fig. 4, which illustrates a state in which air injected into an air cell is forcibly exhausted.

[0087] As illustrated in Fig. 14, the control unit (500) can control the operation of the second common valve member (400) so that the fluid communication between the main supply pipe (60) and the suction pipe (30) is blocked when forcibly discharging air inside the air cell (10).

[0088] That is, when the operation of the second common valve member (400) is controlled to block the fluid communication between the main supply pipe (60) and the suction pipe (30), the intake of external air into the suction pipe (30) is blocked, and only the air inside the air cell (10) can move into the suction pipe (30). In this state, when the air pump (20) operates, it becomes possible to forcibly discharge the air inside the air cell (10), thereby improving the stability of the forced exhaust operation.

[0089] FIG. 15 is a plan view of an air massage device capable of forced exhaust according to one embodiment of the present invention, and is a drawing illustrating a state in which air injected into each air cell is naturally exhausted.

[0090] As shown in FIGS. 13 and 15, the control unit (500) can control the operation of each valve member so that when the air inside the air cell (10) is naturally discharged, the air flowing through the air cell pipe (50) is discharged sequentially through the suction pipe (30) and the main supply pipe (60).

[0091] That is, when naturally discharging the air inside the air cell (10), it is important to minimize the length of the air path. In the case of forced exhaust in which the air pump (20) operates, smooth air discharge is possible even if the length of the path increases, but in the case of natural exhaust, exhaust is achieved only by the air pressure inside the air cell (10).

[0092] Therefore, as described above, by configuring the air inside the air cell (10) to be discharged sequentially through the intake pipe (30) and the main supply pipe (60) when naturally discharged, the length of the path is minimized, enabling smooth natural exhaust of the air cell (10).

[0093] To this end, the control unit (500) blocks the current applied to the first individual valve member (100), and when the first individual valve member (100) is turned off, the air inside the air cell (10) flowing through the air cell pipe (50) does not flow to the supply path (120) of the first individual valve member (100), but moves to the second individual valve member (200) through the air cell pipe (50). In addition, the control unit (500) also blocks the current applied to the second individual valve member (200), and when the second individual valve member (200) is turned off, the air moves to the suction pipe (30) through the discharge path (210) of the second individual valve member (200). In addition, the control unit (500) blocks the current applied to the second common valve member (400), and when the second common valve member (400) is turned off, the air in the suction pipe (30) moves to the main supply pipe (60) through the common supply path (410) and is then discharged to the outside.

[0094] By configuring the air inside the air cell (10) to be discharged while the current is cut off to each individual valve member and common valve member in this way, power consumption can be minimized.

[0095] As illustrated in Fig. 14, the main supply pipe (60) may be arranged to branch off from the main discharge pipe (70). Therefore, when air is injected into the air cell (10), the current to the first common valve member (300) and the second common valve member (400) is cut off and maintained in an off state, so that the air sucked into the main supply pipe (60) moves to the suction pipe (30) through the second common valve member (400), and the air flowing through the discharge pipe (40) moves to the first individual valve member (100) through the first common valve member (300). In addition, when the air inside the air cell (10) is naturally discharged, the current to the first common valve member (300) and the second common valve member (400) is cut off and maintained in an off state, so that the air inside the air cell (10) can be discharged to the outside through the suction pipe (30). In addition, when forcibly discharging the air inside the air cell (10), current is applied to the first common valve member (300) and the second common valve member (400) to keep them in an on state, so that the air inside the air cell (10) can sequentially pass through the discharge pipe (40) and the main discharge pipe (70) via the air pump (20) and then be discharged to the outside.

[0096] As previously discussed, in the air massage device capable of forced exhaust according to one embodiment of the present invention, a first individual valve member (100) and a second individual valve member (200) are provided for each air cell (10), so that even if air is supplied using a single air pump (20), each air cell (10) can operate independently and stably without being influenced by each other, and a first common valve member (300) and a second common valve member (400) are provided so that communication between each air cell (10) and the outside can be controlled, so that air inside the air cell (10) can be forcibly exhausted.

[0097] Although one embodiment of the present invention has been described, the spirit of the present invention is not limited to the embodiments presented in this specification, and those skilled in the art who understand the spirit of the present invention will be able to easily propose other embodiments by adding, changing, deleting, or adding components within the scope of the same spirit, but this will also be considered to fall within the spirit of the present invention.
