Description

A device for controlling the air flow of a cylindrical air massager

[0001] The present invention relates to a device for controlling air flow in a cylinder-type air massager, and more particularly, to a device for controlling air flow of a type in which a central piston moves up and down by rotation of a home cam and a type in which a central piston moves up and down by two cams.

[0002] The air massager, which transmits the expansion force of the airbag generated when air is supplied to the massage area to apply pressure and then releases the air to release the pressure, has a great influence on the effect of stimulating the autonomic nervous system and activating it, which promotes metabolism, depending on the strength of the pressure and the time of the pressure.

[0003] Devices capable of supplying compressed air to airbags include compressors, vacuum pumps, and methods utilizing the air contained in the cylinders of the device itself. Compressors are not suitable for use in massagers due to noise and heat generation. Vacuum pumps used in commercially available air massagers can only be used when air pressure is low, and their timing is difficult to control, making it difficult to achieve a high-quality massage effect.

[0004] Commercially available massagers, such as hand and foot massagers or pain relief devices, have a problem in that they have minimal massage effects and thus cannot meet consumer needs. In addition, a technology for applying a high-function valve controlled by a non-standard gear that controls the airflow of a cylindrical air massager developed by the applicant to a cylindrical air massager in which a home cam operates a central piston must be developed, and there is a problem in that a technology for a cylindrical air massager in which a high-function valve using a standard gear with a protrusion on one side and a spring to correct the position of the protrusion has not been secured.

[0005] Also, the gear 1 with one tooth meshes with the teeth of the standard gear 2.

[0006] There is a problem that the technology has not been developed to enable the high-function valve to operate normally by marking the teeth of the 2nd gear among the teeth of the 1st gear to distinguish between the teeth that engage and the teeth that do not engage when repeating the engagement and disengagement, and assembling the 2nd gear so that the teeth that engage are inserted into the spring during assembly.

[0007] Additionally, there is a problem in that massagers are not developed for specific purposes and thus cannot meet the diverse needs of consumers.

[0008] In addition, the cylinder-type air massager, which controls the airflow with a high-function valve or a solenoid valve controlled by a timer, can massage one area continuously for a set time while sequentially massaging multiple areas. This function is designed to match the full-body meridian massage time, so if used for full-body meridian massage, you can obtain a high-quality massage effect.

[0009] However, for massages for specific areas or for pain relief, it is more effective to use a manual valve because it is easy to supply air by selecting the valve connected to the air bag in contact with the area requiring massage, and long-term massage is required for one or two areas.

[0010] There are various types of manual valves on the market, but since the convenience of use and ease of assembly are almost the same, there is no need to specify one or two types of manual valves. However, the explanation is supplemented by suggesting how to use one or two of them.

[0011] The present invention is intended to solve the above problems, and the purpose of the present invention is to provide a non-standard gear having a number of teeth half that of a standard gear so that a groove provided on the lower surface of a disc cam of a high-function valve can always be stopped at an exact position vertically above a piston valve, so that the high-function valve controlled by the non-standard gear can always operate normally, and to control the air flow of a cylinder-type air massager in which the groove cam operates the central piston to obtain a high-quality massage effect.

[0012] In addition, the purpose is to provide a cylindrical air massager in which a high-function valve is controlled by a standard gear having a protrusion on one side of the standard gear and a spring controls the position of the protrusion, thereby controlling the air flow.

[0013] In addition, the valve can operate normally even when using a standard gear, and another standard gear is a gear with one tooth, No. 1, which rotates, and among the teeth of gear No. 2, the teeth that should mesh with the No. 1 gear tooth and the teeth that should not mesh with the No. 1 gear tooth are marked so that the product can be assembled so that the meshing teeth are fitted into the spring, and the purpose is to enable the high-function valve to operate normally.

[0014] In addition, the purpose is to provide a cylinder-type air massager that can easily select a specific area and sufficiently massage it for a desired period of time by using a manual high-function valve that manually rotates the disc cam of the high-function valve.

[0015] In addition, the purpose is to control the air flow of the cylinder-type air massager by controlling the opening and closing time of a number of solenoid valves with a specially designed timer, thereby achieving a high-quality massage effect.

[0016] Additionally, the purpose is to allow for a long and sufficient massage of a specific area by manually opening and closing the solenoid valve.

[0017] In addition, the purpose is to provide a cylinder-type air massager in which a manual valve that operates a ball valve or gate valve, etc., controls the air flow so that the cylinder-type air massager can obtain a high-quality massage effect.

[0018] In addition, the purpose is to assemble a pressure reducing valve at the bottom of the cylinder so that when the air pressure inside the cylinder rises above a preset required pressure value, the valve opens to release the air, thereby preventing overload on the reduction motor and maintaining a constant pressure on the massage area, so that the air flow of the cylinder-type air massager can achieve a high-quality massage effect.

[0019] In order to achieve the above-mentioned purpose, it is preferable that the non-standard gear controlling the high-function valve according to the present invention be configured so that the number of teeth is half that of the number of teeth configured in the standard gear.

[0020] Additionally, even when it is a standard gear, it is desirable to have a protrusion on one side so that a spring corrects the position of the protrusion so that the high-function valve always operates normally.

[0021] In addition, when the single-toothed gear No. 1 rotates, it is desirable to mark the teeth of the second gear to distinguish between the teeth that are engaged and the teeth that are not engaged, and to assemble the gear so that the teeth that are engaged are inserted into the spring so that the high-function valve can operate normally.

[0022] In addition, it is desirable to assemble a pressure reducing valve (25) at the bottom of the cylinder so that when the air pressure inside the cylinder rises above a preset value, the valve opens to release the air.

[0023] Additionally, when performing a body-specific massage or a pain-relieving massage, it is desirable to configure a manual valve that can arbitrarily control the flow of air so that the desired area can be easily selected and sufficiently massaged for an arbitrary amount of time.

[0024] Additionally, it is desirable to have a solenoid valve controlled by a timer to control the air flow so that the cylinder-type air massager can achieve a high-quality massage effect.

[0025] Additionally, it is desirable to provide various types of cylinder-type air massagers that can meet the needs of consumers.

[0026] For home cams,

[0027] (a) A cylindrical air massager in which a high-function valve controlled by a non-standard gear controls the air flow;

[0028] (b) A type of high-function valve that controls the air flow by a standard gear having a protrusion on the side and a spring that fixes the position of the protrusion;

[0029] (c) A type of high-function valve that controls air flow using a standard gear as the 2nd gear that can identify the teeth that mesh with the teeth of the 1st gear and the teeth that do not mesh with the teeth of the 2nd gear;

[0030] (d) A type in which a manual high-function valve controls the air flow;

[0031] (e) a type in which a solenoid valve controlled by a timer controls the air flow;

[0032] (f) a type in which a manually controlled solenoid valve controls the air flow;

[0033] (g) There is a type that sequentially massages multiple locations by connecting only one hose to the central cylinder and using fittings to connect and disconnect the hose connected to the airbag.

[0034] For two cams,

[0035] (a) A type of high-function valve that controls air flow by a standard gear having a protrusion on the side and a spring that fixes the position of the protrusion;

[0036] (b) A type of high-function valve that controls air flow using a standard gear as the 2nd gear that can identify the teeth that mesh with the teeth of the 1st gear and the teeth that do not mesh with the teeth of the 2nd gear;

[0037] (c) a type in which a manual high-function valve controls the air flow;

[0038] (d) a type in which a solenoid valve controlled by a timer controls the air flow;

[0039] (e) a type in which a manually controlled solenoid valve controls the air flow;

[0040] (f) There is a type that provides intensive massage by connecting only one hose to the central cylinder and using fittings to attach and detach multiple hoses to the air bag attached to the area requiring massage.

[0041] As described above, the high-function valve controlled by the non-standard gear of the present invention and the high-function valve controlled by the standard gear having a protrusion on one side have the advantage of allowing the high-function valve to always operate normally by causing the groove provided on the lower surface of the disk cam (71) to stop at an exact position vertically above the piston valve (73) when the disk cam (71) that sequentially opens and closes a plurality of piston valves while repeating rotation and stop stops.

[0042] In addition, a pressure reducing valve (25) is assembled at the bottom of the central cylinder (20), so that when the air pressure inside the cylinder is higher than a preset value that is excessively high, the valve opens to release the air, thereby preventing overload of the reduction motor and preventing pain caused by excessively strong pressure during massage.

[0043] Additionally, it has the advantage of allowing you to easily select the area that needs massage using a manual valve and massage it sufficiently for the required amount of time.

[0044] Additionally, it has the advantage of being able to sequentially massage multiple locations by connecting only one hose to the cylinder and using fittings to attach and detach hoses connected to multiple airbags.

Terms defined in general dictionaries used in this invention may be interpreted as having the same or similar meaning within the context of the relevant technology, and unless explicitly defined herein, they shall not be interpreted in an ideal or overly formal sense.

[0070] Hereinafter, an embodiment of the present invention for solving the above problem will be described with reference to the attached drawings.

[0071]

[0072] Fig. 1 is a cylinder-type air massager in which a central piston moves up and down by the rotation of a home cam and a high-function valve controls the air flow.

[0073] In a structure in which a base block (30) is assembled on the upper side of a central cylinder (20) on which a central piston (10) is assembled, a main block (42) is assembled on the upper right side of the base block, and a reduction motor (40) is assembled on the main block, a home cam (78), a cylindrical finger (50), and a single-toothed No. 1 gear (59) are assembled on the output shaft (41) of the reduction motor (40), and a first auxiliary block (45) supporting the output shaft (41) on the left side of the No. 1 gear, a gear shaft (55) assembled on the first auxiliary block is a standard gear having a number of teeth that is half of a standard gear, or a protrusion on one side and a spring (97) that adjusts the position of the protrusion, or when the No. 1 gear having one tooth rotates, a mark (116) is provided that can identify the teeth of the No. 2 gear, which is a standard gear, that mesh with the teeth of the No. 1 gear and the teeth that do not mesh with the teeth of the No. 1 gear. When a standard gear (see Fig. 4) is assembled, a third gear (54) having one tooth at the end of the gear shaft (55) and a fourth gear (58) having a number of teeth that are linked with the third gear, which is half that of the standard gear, are assembled, and when the fourth gear rotates, a high-function valve disc cam (71) assembled on the same shaft (57) as the fourth gear rotates and sequentially opens and closes a piston valve (73), and a high-function valve (56) is assembled on the auxiliary block (45), and when the home cam (78) rotates due to the rotation of the output shaft (41) of the reduction motor (40), a protrusion (90) on the upper part of the press bar fitted into the groove (165) of the home cam machined into an ellipse whose radius continuously changes around the circumference of the home cam shaft hole (166) moves up and down according to the change in the height of the groove, so that the press bar (65) and the central piston (10) coupled with the lower part of the press bar move up and down. When the central piston (10) descends, the air inside the central cylinder (20) is pressure-suppressed into the high-function valve (56) through the hose (68).

[0074] The air that is pressurized into the high-function valve (56) is pressurized into the air bag (79) that is connected to the only open cylinder hole (74) among the many cylinder holes (74) provided in the high-function valve and the hose (68), and the expansion force of the air bag is transmitted to the massage area using an auxiliary device such as a belt to compress the massage area, and when the home cam continues to rotate and the central piston rises, the intake and exhaust piston valve (63) is opened to release the air, and while the central piston (10) rises due to the continued rotation of the home cam (78), air is sucked into the central cylinder (20) through the open intake and exhaust piston valve (63), and when the central piston descends again, the intake and exhaust piston valve (63) is closed by the rotation of the cylindrical finger, and when the central piston descends, the air in the cylinder is supplied to the high-function valve, thereby continuously massaging, and the process of opening and closing the intake and exhaust piston valve (63) by the rotation of the cylindrical finger (50) assembled to the output shaft (41) is repeated. When the cylindrical finger (50) rotates and the right finger (49) of the intake / exhaust disc cam shaft (62) pushes the right jaw (84), the intake / exhaust disc cam (60) turns right, and when the cylindrical finger rotates further and the left finger (51) pushes the left jaw (83) of the intake / exhaust disc cam shaft (62), the intake / exhaust disc cam turns left. When the intake / exhaust disc cam alternately rotates left and right, when the thinner side of the lower surface of the intake / exhaust disc cam (60) stops above the intake / exhaust piston valve (63), the ventilation hole (64) of the intake / exhaust piston valve rises above the cylinder hole (85) of the intake / exhaust cylinder block (61) and opens, and when the thicker side of the intake / exhaust disc cam stops above the intake / exhaust piston valve (63), the ventilation hole (64) of the intake / exhaust piston valve goes down into the cylinder hole (85) of the intake / exhaust cylinder block (61), and the valve closes.After the central piston descends to the bottom dead center, the intake and exhaust piston valve (63) is opened just before it meets the part where the groove radius (165) of the home cam shortens, and then the home cam (78) continues to rotate, causing the central piston to rise, and while the central piston rises, air is sucked into the central cylinder through the open intake and exhaust piston valve, and then just before the central piston descends, the intake and exhaust disc cam (60) is rotated by the rotation of the cylindrical finger to close the intake and exhaust valve, and while the central piston descends, the air in the cylinder is pressurized and supplied to the air bag, and while repeating the process, continuously massaging is performed, and when the home cam (78) rotates once, the central piston moves up and down once, supplying and releasing air in the cylinder into the air bag once, and massaging the massage area that touches the air bag once, the single-toothed No. 1 gear (59) assembled on the output shaft also rotates once, and the number of teeth is 1 / 2 of the standard gear and the non-standard gear No. 2 The gear (52) is rotated by a central angle corresponding to one tooth. In the case where the gear 2 is a standard gear with a protrusion on the side, and the gear 1 with one tooth rotates 360° once, the gear 2 rotates by a central angle corresponding to two teeth, the high-function valve can operate normally even when it is a standard gear by creating a protrusion (115) on the side of the gear 2 (52) and controlling the position of the protrusion with a spring (97). (See Fig. 4).

[0075] When the 2nd gear is a standard gear, when the 1st gear with one tooth rotates 360° once, it rotates by the central angle corresponding to two teeth of the 2nd gear, so the teeth of the 2nd gear are marked so that the teeth that mesh with the teeth of the 1st gear and the teeth that do not mesh with them can be identified, and when the massager is stopped, the teeth with the marks are always inserted into the spring (99 in Fig. 4), and the teeth of the 2nd gear that mesh with the teeth of the 1st gear are stopped at the position where the outer teeth of the 1st gear and the teeth of the 2nd gear first meet (see Fig. 6). By considering this, the high-function valve always operates normally.

[0076]

[0077] FIG. 2 is a front view of a home cam, and a line dividing the width of the keyway vertically downward from the center of the shaft hole (166) is extended to designate a central angle of 0° as a reference point, and a groove (165) is machined around the shaft hole (166) as the center, but the groove is machined in an elliptical shape so that the distance from the shaft hole to the groove continues to change, so that when the groove cam rotates in the direction of the arrow while the protrusion (90) of the press bar is fitted into the groove, when the 0° portion of the groove (165) is vertically downward of the shaft hole (166), the distance between the shaft hole (166) and the groove is the closest, so that the protrusion (90) is in a state where it is raised the highest, and thus the press bar (65) and the central piston (10) coupled to the lower end thereof are raised to the top dead center. After that, as the home cam rotates in the direction of the arrow and the a° portion of the home (165) approaches the reference point 0°, the distance between the shaft hole and the home becomes increasingly farther away, so the press bar (66) and the central piston coupled to the bottom of the press bar descend, and when the b° portion, which has the longest distance between the shaft hole and the home (165), comes to the reference point 0° portion, the press bar descends to the bottom dead point, and since the distance of the grooves is the same between b° and c°, it continues to rotate, and while the c° portion rotates to the reference point 0° portion, the central piston is stopped at the bottom dead point.

[0078] From c°, the distance between the shaft hole and the groove becomes shorter, so the press bar rises, and when the 0° portion is vertically below the shaft hole, the distance between the shaft hole and the groove is the closest, so the press bar and the central piston (10) rise to the top dead center, and as the central piston continues to move up and down due to the continued rotation of the groove cam, the air in the cylinder is supplied and discharged into the air bag, so that it can continuously massage.

[0079]

[0080] Figure 3 illustrates a normal operating form in which, when the single-toothed No. 1 gear (59) assembled on the output shaft (41) of the reducer rotates in the direction of the arrow, the tooth (80) of the No. 1 gear enters the space between the teeth 81 and 82 of the No. 2 gear to rotate the No. 2 gear (52). However, when the No. 2 gear (52) is a standard gear, when the single-toothed No. 1 gear rotates 360° once, it rotates by a central angle corresponding to two teeth of the No. 2 gear. For example, if gear 2 is a standard gear with 12 teeth and the teeth of gear 2 are numbered from 1 to 12, when gear 1 (59) first rotates, it is wedged between teeth 1 and 2 of gear 2 (52). When gear 2 is rotated after gear 1 continues to rotate, the teeth of gear 1 and gear 2 are separated, gear 2 stops, and when gear 1 rotates 360° once and meshes with gear 2 again, it is not wedged between teeth 2 and 3, but between teeth 3 and 4, and then between teeth 5 and 6. The teeth of gear 1 mesh with the teeth of gear 2, first tooth 1, then tooth 3, then tooth 5, and then tooth 7. And when the gear 2 is rotated while the teeth of the gear 1 are meshed with the teeth 1 of the gear 2, and when the gear 2 is rotated while meshing with the teeth 2 of the gear 2, the stop position of the gear 2 cannot but be different. Referring to Fig. 5, if the stop position of the gear 2, which determines the stop position of the groove of the disc cam (71), is not accurate, the groove center section (section a) of the disc cam does not stop at the exact position vertically above the piston valve, so the piston valve (73) cannot rise to the groove center section (section a) and cannot open.Therefore, if only the odd-numbered teeth of the second gear that mesh with the teeth of the first gear are left and the even-numbered non-meshing teeth are cut and a non-standard gear with a number of missing teeth that is half that of the standard gear is used, the stop position of the second gear (52) is always constant, so the groove center section (section a) of the disc cam always stops vertically above the piston valve, and the high-function valve can operate normally.

[0081]

[0082] Fig. 4 shows that even when using a standard gear, the teeth that should not be engaged, such as No. 2, No. 4, and No. 6 described in Fig. 3, do not engage, so that a protrusion (115) is made on the side of the No. 2 gear (52) so that the position of the protrusion is corrected with a spring (97) and the teeth that should not be engaged, such as the teeth of the No. 2 gear (59), do not stop at the 22° center angle position of the No. 1 gear (see Fig. 6), so that the high-function valve operates normally even when using a standard gear with a protrusion on the side. In addition, when the No. 2 gear is a standard gear, the teeth that engage with the teeth of the No. 1 gear and the teeth that do not engage are marked with numbers (116), letters, or lines so that the teeth that engage can be identified, so that when disassembling and assembling, it is confirmed that the teeth with the marks are inserted between the springs (99), and when assembling and using, the high-function valve operates normally. And since the gear teeth are inserted between the springs (99), the positions of the gear teeth do not change even when moving or shaking, but when assembling, if you check that the gear teeth with the mark are inserted between the springs (99) and assemble and use them, the high-function valve will operate normally.

[0083]

[0084] FIG. 5A is a partial assembly drawing of a structure in which a disc cam (71) is horizontally assembled on a high-function valve cylinder block (70) and a piston valve (73) is assembled in each hole of the cylinder block. When the disc cam (71) rotates in the direction of the arrow, the piston valve rises due to the elasticity of the spring (75) assembled at the bottom of the piston valve while the inclined surface c section where the height of the groove increases rubs against the piston valve (73), and when the central section of the groove (section a) stops above the piston valve, the vent (72) rises above the cylinder hole (74) of the cylinder block and is exposed to the space of the high-function valve, and when the valve opens, the air inside the high-function valve passes through the vent (72) and is supplied into the air bag (79) through the hose (68). As the disc cam further rotates, while the vent (72) of the piston valve rubs against section b where the height of the groove gradually decreases, the air is blocked by the vent (72) going down into the cylinder hole (74) of the air valve. Therefore, when the disc cam stops, the stop position of the second gear, which repeats rotation and stop, must be constant so that the groove center section (section a) can always stop vertically above the piston valve. Fig. 5 B is a plan view of the disc cam (71), and there is a groove center section (section a) on the lower surface, and on both sides there is a slope section c where the groove height increases and a section b where the groove height decreases.

[0085]

[0086] Fig. 6 is a reference diagram for finding the position where the single-toothed gear 1 (59) first meets the teeth of the second gear (52) as it rotates. When the second gear has a module of 2.5 and 24 teeth, the two teeth meet at a position with a central angle of 22°, so that the teeth that should not mesh at this position do not stop, and the positions of the protrusion (115) and the spring (97) on the side of the gear described in Fig. 4 are determined and used so that the teeth that should not mesh at this position do not stop, the high-function valve can operate normally. In addition, when the position of the spring (99) of Fig. 4 is determined and used so that the teeth marked as tooth 2, etc. that should not mesh with the teeth of the first gear in the description of Fig. 4 do not stop at a position with a central angle of 22°, the high-function valve always operates normally.

[0087]

[0088] Fig. 7 is a drawing for explaining the principle of opening and closing a high-function valve when four gears are interlocked. When the single-toothed No. 1 gear (59) assembled on the output shaft (41) rotates 360° once, the meshed No. 2 gear, which is a standard gear with half the number of teeth of the standard gear or has a protrusion on the side, or when the No. 2 gear (52) is a standard gear, has marks that identify the teeth that mesh with the outer teeth of the No. 1 gear and the teeth that do not mesh, the single-toothed No. 3 gear (54), and the No. 4 gear (58) with half the number of teeth of the standard gear, are interlocked, the disk cam (71) sequentially opens and closes the piston valve (73) while repeating rotation and stop. Specifically, the No. 1 gear (59) assembled on the output shaft (41) of the reduction motor rotates to rotate the No. 2 gear (52). Since the No. 1 gear (59) is an externally toothed gear with only one tooth, when the No. 1 gear (59) rotates 360° once, the No. 2 gear (52), which has half the number of teeth of the standard gear, rotates by a central angle corresponding to one tooth. Then, when the No. 1 gear (59) continues to rotate, the teeth of the No. 1 gear and the teeth of the No. 2 gear disengage, so the No. 2 gear (52) stops, and only the No. 1 gear (59) continues to rotate, meshes with the No. 2 gear again, rotates the No. 2 gear partially, disengages, and then engages again, repeating the operation to rotate the No. 2 gear.

[0089] For example, if the number of teeth of the 2nd gear is 12, when the 1st gear rotates 12 times, the 2nd gear (52) rotates 360° once. When the 2nd gear (52) rotates 360° once, the 3rd gear (54) assembled on the same shaft (55) as the 2nd gear also rotates 360° once to rotate the 4th gear (58). Since the 3rd gear (54) is also an external gear with only one tooth, it rotates by the central angle corresponding to one tooth of the 4th gear (58). When the 4th gear rotates, the disc cam (71) assembled on the same shaft (57) as the 4th gear rotates to open and close the valve. Therefore, the valve opens and closes when the 1st gear rotates the same number of teeth as the 2nd gear. When the valve is opened, air pressured from the central cylinder (20) to the high-function valve through the hose (68) is supplied into the air bag (79) connected to the open valve and the hose (68), and when the air bag generates expansion force, it is transmitted to the massage area using a belt or massage bed to compress the massage area, and then the intake and exhaust piston valve (63) of Fig. 1 is opened to release the air.

[0090]

[0091] Fig. 8 is a piston valve of a high-function valve.

[0092] This is a valve that is lowered by a horizontally assembled disc cam assembled on top of each cylinder hole (74) of a cylinder block (70) and closes when the vent hole (72) goes down into the cylinder hole (74) and opens when the vent hole (72) rises above the cylinder hole (74) by the elasticity of a spring (75) assembled at the bottom. When the valve is opened, the air in the high-function valve is supplied into the airbag through the vent hole (72) and the vertical hole (77) formed at the bottom.

[0093]

[0094] Fig. 9 is a cylinder block of a high-function valve.

[0095] There is a hole in the center that supports a disc camshaft (57) of a high-function valve, and a number of cylinder holes (74) are provided on an arbitrary circumference around the hole.

[0096]

[0097] FIG. 10 shows a structure identical to that of FIG. 1, in which the home cam (78) rotates to move the central piston (10) up and down, and the functions of the cylindrical finger (50), the intake / exhaust disc cam (60), the intake / exhaust cylinder block (61), and the intake / exhaust piston valve (63) are identical to those described in FIG. 1, and when the handle (94) for manually controlling the disc cam (71) of the high-function valve is rotated and the indicator needle (88) is aligned with the scale (95) of the valve hole to be opened, the vent hole (72) of the piston valve (73) assembled in the valve hole rises above the cylinder hole (74) and opens. The air compressed from the central cylinder (20) is supplied into the air bag connected to the open piston valve and hose, massaging the area touching the air bag, and when the disc cam handle is rotated again, the groove on the lower surface of the disc cam moves, closing the piston valve, whether it is open, and then the piston valve rises to the central section (section a) of the groove on the lower surface of the disc cam, and when the vent opens, air is supplied and discharged into the air bag (79) connected to the piston valve and hose, continuously massaging the area touching the air bag. At this time, the manual valve is a manual high-function valve, a manually controlled solenoid valve, a gate valve, a ball valve, etc., and the methods of using the fitting without a valve of FIGS. 14 and 22 are all the same in function and convenience of use, although they are different in form only.

[0098]

[0099] Fig. 11 is a cylinder-type air massager that moves the piston up and down as the home cam rotates, and when the central piston (10) descends, the air in the cylinder is sent to the solenoid valve box (160), and a specially made timer (161) is used.

[0100] This is a cylinder-type air massager that sequentially opens a number of solenoid valves one by one for a preset period of time, supplies and releases air into an air bag (79) connected to the open valve and a hose (68), and continuously massages the area touched by the air bag for several minutes, and then sequentially massages the next area for several minutes.

[0101]

[0102] Fig. 12 is a structure of a cylinder-type air massager that moves the central piston (10) up and down as the home cam (78) rotates, and when the central piston descends, the air in the cylinder is compressed and sent to the solenoid valve box, so that the air is supplied to the air bag touching the area to be massaged. When the switch is selected in the solenoid valve power switch box (155) to supply power to the solenoid valve connected to the air bag, the selected solenoid valve opens, and the air compressed from the central cylinder is supplied and discharged into the air bag connected to the opened valve, so that the area touched by the air bag can be continuously massaged.

[0103]

[0104] Fig. 13 is a cylinder-type air massager that moves the piston up and down as the home cam rotates, and the central piston (10) descends to move the air inside the cylinder.

[0105] When the ball valve type manual valve box (89) is pressurized, the area in contact with the air bag that is in contact with the area requiring massage is opened, and the area in contact with the air bag is continuously massaged. When the valve is closed and the next valve is opened, the area in contact with the air bag connected to the next valve is continuously massaged.

[0106]

[0107] Fig. 14 is a structure of a cylindrical air massager that moves the central piston (10) up and down as the home cam (78) rotates, and by attaching and detaching hoses connected to the cylinder without a valve to each hose connected to the air bag using fittings (110, 120), multiple locations can be sufficiently massaged sequentially.

[0108]

[0109] Fig. 15 is a cylinder-type air massager that moves a piston up and down with two cams, and a high-function valve controlled by two types of standard gears described in Fig. 4 controls the air flow.

[0110] In a structure in which a second cam (66), a first cam (47), a cylindrical finger (50), and a single-toothed first gear (59) are assembled to an output shaft (41) of a reduction motor assembled to the main block, a base block (30) across the upper center of a central cylinder (20) on which a central piston (10) is assembled, a main block (42) assembled on the upper right side of the base block, and when the output shaft (41) rotates, the first cam (47) assembled to the output shaft rotates to lower the first press bar (65), and the second press bar (43) connected to the central piston (10) coupled to the lower part of the first press bar is lowered simultaneously, and when the central piston is lowered, the air in the cylinder is supplied into a high-function valve controlled by the standard gear of FIG. 4, and then supplied into an air bag connected to an open valve among a number of valve holes (74) provided in the high-function valve by a hose, and the expansion force of the air bag is transmitted to the massage area using auxiliary devices such as a belt, a cuff, and a massage bed, thereby providing a massage. After pressing the area, the intake and exhaust piston valve (63) is opened by the rotation of the cylindrical finger (50) to release air, and then the second press bar (43) is raised by the rotation of the second cam (66), so that the central piston (10) connected to the first press bar (46) and the lower part of the first press bar (65) are simultaneously raised by the up-and-down reciprocating motion of the central piston, and the air is released and sucked in by the opening and closing of the intake and exhaust valve, which is composed of the cylindrical finger (50) and the intake and exhaust disc cam intake and exhaust cylinder block (61) described in Fig. 1, to continuously massage the area that is in contact with the air bag.When the single-toothed No. 1 gear (59) assembled on the output shaft (41) rotates, it rotates the No. 2 gear (52). When the No. 2 gear is a standard gear with a protrusion (115), when the No. 1 gear rotates 360° once, the No. 2 gear, which is a standard gear, rotates by a central angle corresponding to two teeth. Therefore, when a standard gear with a protrusion on the side and a spring (97) assembled thereon is used, the central section (section a) of the groove of the disc cam described in FIG. 5 can always be stopped vertically above the piston valve (73), so the high-function valve can operate normally.

[0111] In addition, when the single-toothed No. 1 gear (59) assembled on the output shaft (41) rotates to rotate the No. 2 gear (52), if a standard gear has marks that can identify which teeth of the No. 2 gear mesh with the No. 1 gear and which teeth do not mesh with the No. 1 gear, when the No. 1 gear rotates once 360°, the standard gear No. 2 gear rotates by a central angle corresponding to two teeth, so if a standard gear with marks that can identify which teeth mesh with the No. 1 gear and which teeth do not mesh with the No. 1 gear is used and the meshing teeth are fitted into the spring (99) during assembly, the central section (section a) of the groove of the disc cam described in FIG. 5 can always be stopped vertically above the piston valve (73), so that the high-function valve can operate normally.

[0112]

[0113] Fig. 16 is a first cam (47) that presses and lowers the first press bar (65) with the first eccentric cam.

[0114] When the shortest radius 0° part is rubbed against the first press bar (65) when rotated in the direction of the arrow while assembled on the output shaft, the first press bar (65) and the central piston (10) are at top dead center, and when the central piston (10) descends until the longest radius a° part is rubbed, the air in the central cylinder (20) is pressurized and supplied to the high-function valve (56) through the hose (68), and the air bag (79) connected to the only open piston valve (73) among the piston valves (73) assembled in the multiple cylinder holes (74) provided in the high-function valve and the hose (68) is transmitted to the massage area using an auxiliary device such as a belt or a massage bed to compress the massage area, and when the center angle a° part of the cam with the longest radius of the eccentric cam is rubbed against the press bar (65), the central piston is lowered to the bottom dead center, and the entire amount of air in the central cylinder (20) is supplied to the air bag, and the area in contact with the air bag is compressively pressed. After that, the eccentric cam rotates, and the central piston (10) is stopped at the bottom dead center until the central angle b° portion rubs against the first press bar (65), so the air supplied to the air bag remains stationary and in a pressurized state, and from b° to 0°, the radius of the eccentric cam is rapidly shortened, so it rotates without touching the first press bar (65).

[0115]

[0116] Fig. 17 shows a second eccentric cam, and while the central angle b° portion of the first eccentric cam of Fig. 16 is rubbed against the first press bar (65), and the portion of the first eccentric cam whose radius is rapidly shortened rotates without touching the first press bar, the second cam (66) is rubbed against the second press bar, and then the portion of the eccentric cam whose radius is gradually lengthening is rubbed against the second press bar, thereby raising the second press bar (43), and the first press bar connected to the second press bar by a link (46) and the central piston (10) coupled to the lower end of the first press bar are raised to the top dead center, and then the first cam lowers the central piston again, repeating the operation. Thus, the first cam lowers the central piston and the second cam raises the central piston, so that the first cam and the second cam move the central piston up and down.

[0117]

[0118] Fig. 18 is a cylinder-type air massager in which a high-function valve (98) manually controlled by two cams moves a piston up and down to control the air flow.

[0120] By rotating the first and second cams, the central piston moves up and down, and when the piston descends, the air inside the cylinder is pressurized and fed into the manual high-function valve (98). When the disc cam handle (94) is rotated by hand so that the air is supplied into the air bag that touches the area that needs to be massaged among the multiple cylinder holes (74) provided in the manual high-function valve (98), and the indicator needle (88) is aligned with the scale (95), the air pressurized from the central cylinder is continuously supplied and discharged into the air bag that touches the desired area, thereby continuously massaging the area.

[0121] In this process, the operation of the cylindrical finger and the suction / discharge valve is as described in Fig. 1, and the manual high-function valve (98) is controlled by turning the disc cam handle (87) by hand and aligning the indicator needle (88) with the mark (95) of the cylinder hole you want to open, and until you turn the handle (87) by hand again, the air is continuously supplied and discharged into the air bag connected to the open cylinder hole, so that only that area can be intensively massaged, and when you turn the disc cam handle (87) again, the valve that was open closes and then the next valve opens.

[0122]

When only one ball valve type manual valve (87) is opened, air is supplied and discharged into an air bag (79) connected to the open valve and a hose, thereby continuously massaging the area in contact with the air bag (79). When the open valve is closed and another valve is opened, air is supplied and discharged into an air bag connected to a newly opened valve and a hose, thereby continuously massaging the area in contact with the air bag.

[0125]

After a continuous massage, the valve that the timer (161) is open is closed and then the valve is opened for 3 minutes. Then, the area that is in contact with the newly opened solenoid valve and the air bag connected to the hose is massaged for 3 minutes, and other areas can be sequentially massaged for 3 minutes each.

In a structure in which a main block (42) assembled on the upper right side of the base block, a reduction motor (40) assembled to the main block, a first auxiliary block (45), a second auxiliary block (48), a third auxiliary block (53) supporting an output shaft (41) of the reduction motor (40), a first cam (47), a second cam (66), and a cylindrical finger (50) are assembled to the output shaft (41), when the output shaft (41) rotates, the first cam (47) rotates, and the second press bar (43) connected to the first press bar (65) by a link (46) and the central piston (10) coupled to the lower end of the first press bar (65) simultaneously descend, and an intake / exhaust piston valve (63) that opens just before the central piston (10) rises and closes just before it descends, an intake / exhaust valve disc cam (60) that opens and closes the intake / exhaust piston valve (63), and the intake / exhaust valve disc cam moves left and right. It further includes a cylindrical finger (50) that rotates alternately, and as the cylindrical finger (50) rotates with the continued rotation of the output shaft (41), the intake and exhaust valves are opened to discharge air, and then the central piston (10) coupled with the lower end of the first press bar (65) connected to the second press bar (43) by the link (46) is simultaneously raised by the rotation of the second cam (66), and while the central piston is rising, air is sucked into the central cylinder (20) through the intake and exhaust piston valve (63) that is open, and then the intake and exhaust valve is closed by the rotation of the cylindrical finger (50), and the air in the central cylinder (20) is supplied and discharged into the air bag by the central piston (10) that descends with the rotation of the first cam (47), thereby providing a continuous massage. A device for controlling the air flow of a cylinder-type air massager, characterized by a cylinder-type air massager having a pressure reducing valve (25) assembled therein that opens when the air pressure inside the central cylinder rises above a preset value.

14. A central cylinder (20) having a central piston (10) assembled thereon, a base block (30) assembled on the upper side of the central cylinder, a main block (42) assembled on the upper right side of the base block, a reduction motor (40) assembled to the main block, a first auxiliary block (45) and a second auxiliary block (53) supporting an output shaft (41) of the reduction motor (40) are assembled, and a first cam (47), a second cam (66), and a cylindrical finger (50) are assembled to the output shaft (41). When the output shaft (41) rotates, the first press bar (65) descends due to the rotation of the first cam (47), and the second press bar (43) connected to the first press bar by a link (46) and the central piston (10) in contact with the lower end of the first press bar (65) descend to the bottom dead center. When the central piston (10) descends, the air in the central cylinder (20) is pressurized and supplied to the manual high-function valve (98) through the hose (68), and when the disc cam handle (94) is manually rotated and the indicator needle (88) is aligned with the scale (95) that matches the valve connected to the air bag (79) and the hose (68) that touches the area to be massaged, air can be continuously supplied only to the desired area, so that only that area can be continuously massaged, and a cylinder-type air massager further includes an intake / exhaust piston valve (63) that opens just before the central piston (10) rises and closes just before it descends, an intake / exhaust valve disc cam (60) that opens and closes the intake / exhaust piston valve (63), and a cylindrical finger (50) that alternately rotates the intake / exhaust valve disc cam left and right, and a pressure reducing valve (25) that opens when the air pressure in the central cylinder rises above a preset value, characterized in that the manual high-function valve controls the air flow. A device that controls the air flow of a massager.
