To the air room. Fig. 3 is a schematic view showing an outline of an embodiment of the pneumatic massager of the present invention. The body for the massager is installed on the upper limb and the lower limb, and is massaged by a finger from the finger to the shoulder or from the toe to the thigh. The compressed air supplied to the lower limbs via the three-way valves V 1 to V 4 is divided into two by the adapter 13 and introduced into the massage bag body attached to the two lower limbs. After the user inputs the power of the massager main body 5, the switching mechanism provided in the massager main body 5 is turned on to start the massage (operation). At this time, the basic operation of the massager is to operate the air pump 5 (refer to FIG. 1) at the start of operation, and the compressed air is supplied to the tank 7. The control unit 8 is based on the pre-memorized button (setting mode). The energization of each of the electromagnetic coil units 3 is turned on and off, and the switching of the three-way valves VI to V4 is performed. The setting mode is, for example, firstly inflated from the air chamber 1 1 a on the front side and sequentially in the air chamber 1 d on the thigh side, and then the exhaust vortex is repeatedly oscillating mode -10- (8) 1290044 (A mode) The air chamber 1 1 a from the front side of the edge is sequentially inflated for the air chamber 1 1 d on the thigh side, and the air chamber 1 is held for a predetermined set of pressures for a certain period of time for the air chambers 1 la 1 1 Id La~1 Id is simultaneously squeezed in the squeezing mode (B mode), and the air chambers 1 la 〜1 Id are simultaneously inflated at the same time, and the set air pressures are specified for the air chambers 1 la 〜1 Id The exhaust mode is performed at the same time after a certain period of time, but it is not limited to the above, and it is possible to set various modes of φ. Further, it can be set to an arbitrary operation time, and is operated by the setting mode according to the set end time. Fig. 4 is a flow chart showing the pressure abnormality detection in the pneumatic massager abnormality detecting system of the present invention and the corresponding sequence. As shown in Fig. 4, the sequence is composed of step S1 from step S1 to step S25, and abnormal mode operation. Here, the steps S 1 1 to S 19 are related to the preparation operation before the start of the pressing, and the steps S 20 to S 25 are the authors of the actual massage. Further, the specific one is as described later, and step S 2 2 is set to φ in the setting mode to constitute a different detailed step. In step S1 1 , it is determined whether the power source is turned on (power input), and if it is determined that the power is turned on, the process proceeds to step s 1 2 • in step s 1 2, it is determined that the pressure sensor 9 is on the side of the pressure sensor 9 Whether the pressure is above the specified pressure P1 (for example, 1 7 · 7 kP a ). Step S1 2 is to detect whether or not a short circuit of the pressure sensor 9 occurs (the pressure is infinite due to a failure) and the air pump is detected in the standby operation until the start of the operation of the step s 13 6 Unable to stop any of the exceptions. Moreover, "Pa" is the meaning of the pressure unit "Pascal" (the atmospheric pressure is approximately equal to -11 - (9) 1290044 lOOkPa). When the pressure is determined to be equal to or greater than the specified pressure P1, the abnormal mode of step S50 operates. In the abnormal mode operation, the operation of the air pump 6 is stopped, the valve V 1 to V 4 is closed, the buzzer is turned ON, and the power lamp is turned off. And, in step S12, if the pressure is judged not to be above the designated transition, the process proceeds to step S1 3 of the operation start step, and it is judged whether it is the start, and if it is determined that the operation is started, the process proceeds to step φ. After the "three-way valve V1 is turned on" in S14, the three-way valve v1 is closed after the specified time (for example, 5·5 seconds). The step S1 is performed to remove the residual pressure in the tank 7. . Further, in the step S1 5 in which the timer 1 is measured in the timer 1 in the control unit 8, it is determined whether or not the pressure is equal to or lower than a predetermined pressure, for example, 0.4 kPa). In step S15, when it is determined that the pressure system is not below the pressure, the process proceeds to the abnormal mode of step S50, and when it is determined that the pressure is below the specified pressure, the process proceeds to step S16 to specify the input ##40%) Drive air pump 6 (specify the output air pump). In step S15, it is determined whether or not the step s 14 is normal, and it is detected whether an abnormality of the three-way valve VI or an abnormality of the pressure sensor 9 (the pressure is infinite due to the failure) occurs. In the subsequent step S17, it is determined that after step S16, the specified time T2 (e.g., 1·5 second) reaches the designated pressure P3 4 kPa or more), and if it is determined that it has not arrived, the process proceeds to step S50. In step S17, when it is determined that the pressure P3 or more is specified within the designated time 12, the process proceeds to the pre-pressure mode step and proceeds to execution: 3. Alarm! Force P1 is determined to operate S14. At t1 (Example 4 moves each finger. In the case of P2 (in the case of the designation is in the out (such as driving the walk, and whether the short circuit is in (for example, the abnormal system arrives at step -12-(10) 1290044 S 1 8 and the pre-pressure is started. Step S 1 7 ' It is judged whether the pressure is increased at the normal speed after the step s 1 6 , and accordingly, whether the open circuit of the pressure sensor occurs (the pressure is measured due to the failure), the air pump 6 cannot be operated, and the action cannot be closed. The directional valve V4, the full rupture of the pressure sensor passage 16 (completely impassable), and the abnormality of either the breaking (without pressure) and the half of the pressure sensor passage 16 (approximately no pass). φ In step S 18, It is a pre-pressure mode in which the air chamber 1 1 a~1 1 d is only about time and the air supply is started at the same time, and the exhaust gas is exhausted after reaching the pressure, and the mode pressure is only determined when the set pressure is reached ( In the subsequent step S1 9 , the mode is set to an arbitrarily selected setting, and the setting mode lamp which is indicated as the preset setting mode is turned on. The massage operation of the massager is ended. In the previous operation, the following massage operation is used. In the following description, the B mode is used as the sub-men, and the opening and closing timing of the three-way valves VI to V4 is as shown in Fig. 6. In Fig. 6, the three-way valve is used. The operation of V1 indicates that when the electromagnetic coil portion 3 of the three-way valve V1 is energized at time t0, the pressure of the air chamber connected by the three directions starts to rise, and reaches the set force at 110. After the specified time is set to hold the set pressure, and the energization is stopped at t20, the three-way valve V1 is in the exhaust state, and the air pressure is returned to zero. The opening and closing operations of the other three-way valves V2 to V4 are based on the timing. In the same manner as in the step S20, it is determined that when the three-way valve VI is opened, the detection force is set to VI to the difference in the rupture rupture, and the grading is set as an example. The pattern of the parking room is over-the--13- ( 11) 1290044 After a predetermined time (for example, 0.3 seconds), 'is the specified pressure P4 (for example, 1 kPa) or less. If it is determined that the specified time t4 is not equal to or less than the specified pressure P4, the abnormal mode operation of the step S50 is entered. On the other hand, if it is determined that the specified time t4 is equal to or less than the specified pressure P4, the process proceeds to step S2 1 . Step S 2 0 is to determine whether the pressure of the three-way valve V 1 is immediately after a certain degree of pressure. With the removal of the box, it is detected whether or not the occurrence of an abnormality in the three-way valve V1 and the closing of the three-way valve VI cannot occur. In step S21, it is determined whether or not the specified pressure P5 (e.g., 0.4 kPa) or more after a predetermined time t5 (e.g., 4 seconds) has elapsed after the three-way valve VI is opened. When it is not the predetermined pressure P5 or more after the lapse of the designated time t5, the operation proceeds to the abnormal mode operation in the step S50. If it is determined that the predetermined pressure P5 or more is after the lapse of the designated time t5, the process proceeds to step S22. In order to judge whether the sensor 9 is normally operated after the elapse of time from the opening operation of the three-way valve VI, at the same time, the opening of the pressure sensor 9 is detected (the pressure is measured due to the failure), and the pressure sensor path is 16 An abnormality occurs in any of the breakage, the half of the pressure sensor passage 16 and the inability of the air pump 6 to operate. Further, the operation of step S22 (part A of the broken line) will be described in detail later with reference to FIG. 5. Fig. 5 is a detailed flow chart showing the step S22. In step s3, it is determined whether the pressure has reached the specified pressure. If it is determined that the pressure has not arrived, the process proceeds to step S32. In the step S32, various setting modes (for example, A mode, B mode, and C mode) are determined. Whether the corresponding setting mode has passed the specified time 17 (for example, the A and B modes are 60 seconds, and the c mode is -14-(12) 1290044 90 seconds). If the time has elapsed, the process proceeds to the abnormal mode action of step S50. . In step S32, it is determined whether the pressure rises at the normal speed corresponding to the various modes, and at the same time, it is detected whether the pressure sensor 9 is turned on (the pressure is zero due to the fault), and the pressure sensor path 16 Fully broken or detached and broken, half of the pressure sensor passage 16 is broken, the air pump 6 cannot be operated, the three-way valve V 1 to V4 cannot be opened, and the three-way valve V 1 to V4 cannot be closed. An abnormal φ occurs. In step S31, if it is determined that the set pressure is reached, the process proceeds to step S3. 3. In step S33, it is determined whether or not the specified pressure is higher than the set pressure P6 (for example, 2 kPa) or more, and the specified time t6 has elapsed ( For example, if it is determined that the set pressure is higher than the set pressure P6 and the predetermined time t6 has elapsed, the process proceeds to the abnormal mode operation of step S50. If it is determined that the predetermined pressure P6 is higher than the set pressure P6 and the specified time t6 has not elapsed, the process proceeds to step S34. Step S33 is: • continuously monitor whether the pressure is above the allowable range during the operation, and continue. It is detected whether or not a short circuit of the pressure sensor 9 occurs (the pressure is measured to be infinite due to a failure), and an abnormality of any one of the pneumatic pumps 6 cannot be stopped. Next, in step S34, it is determined whether the three-way valve V2 is in the open state. If it is determined to be in the open state, the process proceeds to step S3. 5. In step S35, it is determined whether the pressure reaches the set pressure, and if it is determined that the pressure is not reached, the process proceeds. Go to step S36. In step S36, it is determined whether or not the designated time 17 has elapsed in the various setting modes. If it is determined that the time has elapsed, the process proceeds to the abnormal mode of step -15-(13) 1290044. In step S3-6, it is determined whether the pressure is increased at the normal speed corresponding to the various setting modes, and at the same time, whether the opening of the pressure sensor 9, the full folding of the pressure sensor passage 16 or the like is detected The removal and breaking, the half of the pressure sensor supply flow path is broken, the air pump 6 is not operated, the three-way method VI to V4 cannot be opened, and the three-way valve V 1 to V4 cannot be closed. An exception occurred. If it is determined in step S35 that the set pressure is reached, the process proceeds to step S37. The step S3-7 determines whether the set pressure is higher than the specified pressure P6 and thus passes the designated time t6, as determined. When the set pressure is higher than the predetermined pressure P6 and the predetermined time t6 has elapsed, the process proceeds to step S38. The step S37 is to continuously monitor whether the pressure is higher than the allowable range or higher during the operation. At the same time, it is possible to detect whether or not a short circuit of the pressure sensor 9 occurs (the pressure is measured to be infinite due to a failure), and an abnormality of any one of the pneumatic pumps 6 cannot be stopped. Next, in step S38, it is determined whether the three-way valve 3 is in an open state, and if it is determined to be in an open state, the process proceeds to step S39. In step S39, it is determined whether the pressure reaches the set pressure, and if not, then Proceeding to step S40, in step S40, it is determined whether or not the specified time has elapsed in the various setting modes, and if it is determined that the system has passed, the process proceeds to the abnormal mode of step S50. In step S40, it is determined whether the pressure rises at the normal speed corresponding to the various setting modes, and at the same time, it can be detected whether the opening of the pressure sensor 9, the full folding or the pulling and breaking of the pressure sensor passage 16 and the breaking are detected. The pressure sensor supply flow path is broken by half of the flow path, and the air can not be operated. 16- 1290044 (14) Pu 6 and three-direction method v; [~V4 cannot be opened, and the three-way valve V 1 cannot be closed. Any one of the exceptions occurred. When it is determined in step S392 that the set pressure is reached, the process proceeds to S4 1 . In step S41, it is determined whether the set pressure is higher than the finger force P6 and the specified time t6 has elapsed. When the force is higher than the specified pressure and the specified time t6 has elapsed, the abnormal mode operation to S50 is entered. When it is determined that the set pressure is not equal to the set pressure φ, the specified time t6 is passed, and then the process proceeds to step S4 1 to continuously monitor whether the pressure is continued at a higher allowable fan height during the operation, and at the same time, It is detected whether a short circuit of the pressure sensor occurs (the measured pressure is infinite due to the failure), and the abnormality of any of the pump 6 cannot be stopped. In step S42, it is determined whether the three-way valve V4 is in the state, and if it is determined to be in the open state, the process proceeds to step S43. • In the step, it is determined whether the pressure reaches the set pressure, and if it is not arriving, Step S44. In step S44, it is determined whether or not the specified time t7 has elapsed in the various settings. If the system has passed, how to proceed to the abnormal mode of S50. In step S44, it is determined whether the pressure rises at a normal speed corresponding to the various fixed modes, and at the same time, whether the opening of the pressure sensor 9, the full-folding of the pressure sensor passage 16 and the breaking, the pressure sensor supply can be detected. The flow path is broken by 6 half, the air pump 6 is operated, the three-way method VI to V4 cannot be opened, and the valve VI to V4 cannot be closed. If it is determined in step S43 that the set pressure is reached, then the step V4 is stepped and the constant pressure step is high. S42. The pneumatic opening of the square S43 is entered into the fixed mold step or cannot be tripped into the square- 17-(15) 1290044 Step S45. In the step S45, it is determined whether the pressure pressure P6 is set to be the same as the specified time t6, and if the pressure is determined to be the pressure of the local finger pressure P6 or more, the specified time is entered. The abnormal mode of step S50. When it is determined that the predetermined time 16 has elapsed after the predetermined pressure P 6 or more is exceeded, the step S46 and the step S37 are continued to continuously monitor whether the pressure is higher or higher during the operation, and it is possible to detect whether or not the φ is generated. The short circuit of the device 9 cannot stop any of the pneumatic pumps 6 . In the subsequent step S46, the three-way valves VI to V4 are configured to exhaust the air chambers 11a to 11d. Next, in the step, when the pressure in the exhaust gas is equal to or higher than the specified pressure P1, the abnormal mode of the S50 operation is performed. In step S47, it is detected that the force is not down, and it is possible to detect whether or not the pressure sensing path is generated, and the abnormality of any one of the pneumatic pumps 6 cannot be stopped. Referring back to FIG. 4, in step S25, It is determined whether the arbitrarily turning time is over (time is up). If the time is not up, the process returns to the step and returns to the control of the connection. If the time is up, the control device ends. By the above, the present invention is capable of detecting that between the start of the power-on, the start of the operation, and the designated pressure of the air pump, the specified pressure drive of the air pump and the pre-pressure mode start the first pressure mode start and time to, In the case of the abnormality of each part of the exhaust gas during the operation of the exhaust gas, and the frequent monitoring is set to 16 for the high designation system, the pressure is set to the step that the abnormality of the allowable pressure sense is turned off. , enter the step S20 of the short 〇 setting of the exhaust ejector 9 (between the pneumatic press and the running movement, between the pre-middle (except in the pneumatic press -18 - (16) 1290044) An abnormal situation allows the user to use the pneumatic massager with ease and comfort. Moreover, in step S22 (shown in broken line A of Fig. 4 shown in detail in Fig. 5), each three-way valve V1 can be detected because it is performed. Since the opening and closing operation of the ~V 4 is performed by the determination of the abnormality, regardless of the type of the setting mode, or even before the passage of the valve opening and closing operation in the setting mode, the gas can be detected. The abnormality of each part of the massager progresses to the abnormal mode action of step S50, so that the user can quickly and comfortably use the pneumatic φ massager.
