Description

Technical Field

[0001] The invention relates to a negative pressure massage device used for massage and a use method thereof. Background Art

[0002] In recent years, with the development of social industrialization and informatization, people generally lack exercise. Whether using computers, watching TV, playing video games, or sitting on airplanes for a long time, we often maintain a bad sitting posture. These sitting postures make our head, neck, shoulders, chest, hips or abdomen muscles often tense, leading to tension headaches and neck and shoulder pain. Such conditions may also hinder the normal blood circulation in the brain, causing people to often feel tired and have difficulty concentrating.

[0003] In order to allow people to fully relax and rest in their limited free time, many kinds of massage equipment have appeared on the market, such as negative pressure massage devices. A general negative pressure massage device includes a main unit, a hose and a vacuum cup. The two ends of the hose are connected to the main unit and the vacuum cup respectively. The user can control the pressure in the vacuum cup through the main unit to achieve a relaxing massage effect.

[0004] However, general negative pressure massage equipment does not have the function of adjusting pressure. Due to the different physiological structures and organ positions of different parts of the human body, general negative pressure massage equipment is difficult to optimally adapt to different parts of the human body, and it is also difficult to adapt to different massage objects, such as the elderly and children, men and women, etc. This not only brings operational problems, but also increases the cost of manufacturing multiple sets of equipment.

[0005] In view of this, how to design a negative pressure massage device with adjustable pressure and a method of using the same is one of the problems that need to be solved urgently. Summary of the invention

[0012] In some embodiments, the first flow rate, the second flow rate, and the third flow rate generated when the third solenoid valve is turned on are all equal.

[0013] In some embodiments, the negative pressure massage device also includes a fourth solenoid valve connected to the vacuum pump, the opening end, the first solenoid valve, the second solenoid valve and the third solenoid valve, and electrically connected to the control board; when the first solenoid valve, the second solenoid valve, the third solenoid valve and the fourth solenoid valve are opened at the same time, the vacuum pump remains connected to the opening end.

[0014] In some embodiments, the first flow rate, the second flow rate, the third flow rate, and the fourth flow rate generated when the fourth solenoid valve is turned on are all equal.

[0015] The present invention provides a negative pressure massage device, comprising: a vacuum pump connected to an open end; a first solenoid valve connected to the vacuum pump and the open end; a second solenoid valve connected to the vacuum pump, the open end and the first solenoid valve; a third solenoid valve connected to the vacuum pump, the open end, the first solenoid valve and the second solenoid valve; and a control panel electrically connected to the vacuum pump, the first solenoid valve, the second solenoid valve and the third solenoid valve; the vacuum pump, the first solenoid valve, the second solenoid valve and the third solenoid valve are arranged in parallel with each other.

[0016] In some embodiments, when the first solenoid valve is opened and the second solenoid valve and the third solenoid valve are closed, the vacuum pump maintains communication with the open end.

[0017] In some embodiments, when the first solenoid valve and the second solenoid valve are opened and the third solenoid valve is closed, the vacuum pump maintains communication with the open end.

[0018] In some embodiments, when the first solenoid valve, the second solenoid valve, and the third solenoid valve are opened simultaneously, the vacuum pump maintains communication with the open end.

[0019] In some embodiments, a first flow rate generated when the first solenoid valve is turned on is equal to a second flow rate generated when the second solenoid valve is turned on.

[0020] In some embodiments, the first flow rate, the second flow rate, and the third flow rate generated when the third solenoid valve is turned on are all equal.

[0021] In some embodiments, the negative pressure massage device further includes a fourth solenoid valve connected to the vacuum pump, the opening end, the first solenoid valve, the second solenoid valve and the third solenoid valve, and electrically connected to the control board; when the first solenoid valve, the second solenoid valve, the third solenoid valve and the fourth solenoid valve are opened at the same time, the vacuum pump remains connected to the opening end.

[0026] In some embodiments, when the first solenoid valve, the second solenoid valve, and the third solenoid valve are opened or closed, the vacuum pump is connected to the open end, and the vacuum pump is maintained in an open state.

[0027] In summary, the negative pressure massage device and its use method of the present invention are difficult to optimally adapt to different parts of the human body and different massage objects, such as the elderly and children, men and women, etc., compared with the existing negative pressure massage equipment. In the negative pressure massage device of the present invention, the user first turns on the main power of the negative pressure massage device, and then the control panel controls the vacuum pump to be turned on and the first solenoid valve, the second solenoid valve and the third solenoid valve to be turned on or off. The control panel can control the flow rate by opening the first solenoid valve alone, the second solenoid valve alone, the third solenoid valve alone, the first solenoid valve and the second solenoid valve at the same time, the first solenoid valve and the third solenoid valve at the same time, the second solenoid valve and the third solenoid valve at the same time, and the first solenoid valve, the second solenoid valve and the third solenoid valve at the same time, so as to achieve more diverse negative pressures that change with time, so as to achieve different massage effects and purposes. It also solves the technical problem that it is difficult to optimally adapt to the massage state of each part of the human body or the massaged object in the prior art, so as to save costs and improve the use efficiency. Furthermore, in the negative pressure massage device of the present invention, the first flow rate, the second flow rate and the third flow rate are all equal, which can simplify the operation mode. For example, the user does not need to adjust the flow rate of each solenoid valve, and can combine different flow rate requirements by simply opening or closing. In addition, regardless of whether the first solenoid valve, the second solenoid valve and the third solenoid valve are opened or closed, the vacuum pump can remain connected to the opening end and continue to operate, so that the vacuum pump will not generate negative pressure at the opening end when it is opened, causing energy waste.

[0044] The detailed description and technical contents of the present invention are described below with reference to the accompanying drawings. However, the accompanying drawings are only provided for reference and description and are not intended to limit the present invention.

[0045] As used herein, terms such as "first", "second", etc. describe various elements, components, regions, layers and / or parts, which should not be limited by these terms. These terms can only be used to distinguish one element, component, region, layer or part from another. Unless the context clearly indicates, the terms such as "first", "second" used in this article do not imply a sequence or order.

[0046] Figure 1 This is a system architecture diagram of the first embodiment of the negative pressure massage device 1 of the present invention, please refer to Figure 1 As shown, the negative pressure massage device 1 according to the first embodiment of the present invention comprises a vacuum pump 10 , a first solenoid valve 11 , a second solenoid valve 12 , a third solenoid valve 13 and a control panel 15 .

[0047] The vacuum pump 10 is connected to the open end 16. When the vacuum pump 10 is turned on, a first negative pressure value 101 can be generated at the open end 16. The first negative pressure value 101 is the difference between the atmospheric pressure of the environment and the pressure at the open end 16. When the vacuum pump 10 is turned on, the first negative pressure value 101 is a positive value. The smaller the pressure at the open end 16, the greater the first negative pressure value 101. When the vacuum pump 10 is turned off, the pressure at the open end 16 is the same as the atmospheric pressure of the environment. Of course, according to different definitions, the negative pressure value can also be a negative value, which is not restrictive here.

[0048] The first solenoid valve 11 is connected to the vacuum pump 10 and the opening end 16. When the first solenoid valve 11 is opened, the air outside the negative pressure massage device 1 can flow in through the first solenoid valve 11, thereby adjusting the pressure at the opening end 16. The amount of air flowing into the first solenoid valve 11 per unit time is the first flow rate 111, and the amount of air can be defined by volume or mass or other definitions. When the first solenoid valve 11 is set to a larger cross-sectional area, the first flow rate 111 is larger. When the first solenoid valve 11 is closed, the air outside the negative pressure massage device 1 cannot flow in through the first solenoid valve 11.

[0049] The second solenoid valve 12 is connected to the vacuum pump 10, the opening end 16 and the first solenoid valve 11. When the second solenoid valve 12 is opened, the air outside the negative pressure massage device 1 can flow in through the second solenoid valve 12, thereby adjusting the pressure at the opening end 16. The amount of air flowing into the second solenoid valve 12 per unit time is the second flow rate 121, and the amount of air can be defined by volume or mass or other definitions. When the second solenoid valve 12 is set to a larger cross-sectional area, the second flow rate 121 is larger. When the second solenoid valve 12 is closed, the air outside the negative pressure massage device 1 cannot flow in through the second solenoid valve 12.

[0050] The third solenoid valve 13 is connected to the vacuum pump 10, the opening end 16, the first solenoid valve 11 and the second solenoid valve 12. When the third solenoid valve 13 is opened, the air outside the negative pressure massage device 1 can flow in through the third solenoid valve 13, so as to adjust the pressure at the opening end 16. The amount of air flowing into the third solenoid valve 13 per unit time is the third flow rate 131, and the amount of air can be defined by volume or mass or other definitions. When the third solenoid valve 13 is set to a larger cross-sectional area, the third flow rate 131 is larger. When the third solenoid valve 13 is closed, the air outside the negative pressure massage device 1 cannot flow in through the third solenoid valve 13.

[0051] It is worth mentioning that the vacuum pump 10, the first solenoid valve 11, the second solenoid valve 12 and the third solenoid valve 13 are arranged in parallel with each other, and when at least any one of the first solenoid valve 11, the second solenoid valve 12 and the third solenoid valve 13 is opened, the vacuum pump 10 maintains communication with the opening end 16. That is, when the first solenoid valve 11 is opened or closed, the communication between the vacuum pump 10 and the opening end 16 will not be blocked. Alternatively, when the second solenoid valve 12 is opened or closed, the communication between the vacuum pump 10 and the opening end 16 will not be blocked. Alternatively, when the third solenoid valve 13 is opened or closed, the communication between the vacuum pump 10 and the opening end 16 will not be blocked. In other words, regardless of whether the first solenoid valve 11, the second solenoid valve 12 and the third solenoid valve 13 are opened or closed, the vacuum pump 10 can maintain communication with the opening end 16 and continue to operate.

[0052] The control board 15 is electrically connected to the vacuum pump 10, the first solenoid valve 11, the second solenoid valve 12 and the third solenoid valve 13. The control board 15 can control, for example, opening or closing at least one of the vacuum pump 10, the first solenoid valve 11, the second solenoid valve 12 and the third solenoid valve 13.

[0053] In some embodiments, when the first solenoid valve 11 is opened, and the second solenoid valve 12 and the third solenoid valve 13 are closed, the vacuum pump 10 is maintained in communication with the open end 16. In other embodiments, when the first solenoid valve 11 and the second solenoid valve 12 are opened, and the third solenoid valve 13 is closed, the vacuum pump 10 is maintained in communication with the open end 16. In still other embodiments, when the first solenoid valve 11, the second solenoid valve 12 and the third solenoid valve 13 are opened at the same time, the vacuum pump 10 is maintained in communication with the open end 16. In this way, different operation modes of the negative pressure massage device 1 can be increased.

[0054] It is worth mentioning that the first flow rate 111 generated when the first solenoid valve 11 is turned on is equal to the second flow rate 121 generated when the second solenoid valve 12 is turned on. Furthermore, the first flow rate 111, the second flow rate 121, and the third flow rate 131 generated when the third solenoid valve 13 is turned on can all be equal, but this is not intended to limit the present invention. In other words, the first flow rate 111, the second flow rate 121, and the third flow rate 131 can all be equal.

[0055] As mentioned above, compared with the existing negative pressure massage equipment, it is difficult to optimally adapt to different parts of the human body, and it is also difficult to adapt to different massage objects, such as the elderly and children, men and women, etc. In the negative pressure massage device 1 of this embodiment, the user first turns on the main power of the negative pressure massage device 1, and then the control board 15 controls the vacuum pump 10 to be turned on and controls the opening or closing of the first solenoid valve 11, the second solenoid valve 12 and the third solenoid valve 13. The control board 15 can control the flow rate by opening the first solenoid valve 11 alone, opening the second solenoid valve 12 alone, opening the third solenoid valve 13 alone, opening the first solenoid valve 11 and the second solenoid valve 12 at the same time, opening the first solenoid valve 11 and the third solenoid valve 13 at the same time, opening the second solenoid valve 12 and the third solenoid valve 13 at the same time, and opening the first solenoid valve 11 and the second solenoid valve 12 and the third solenoid valve 13 at the same time, so as to achieve more diverse negative pressures that change with time, so as to achieve different massage effects and purposes. And solve the technical problem that the prior art is difficult to optimally adapt to the massage state of each part of the human body or the massaged object, so as to achieve the purpose of saving costs and improving use efficiency. Furthermore, the negative pressure massage device 1 of this embodiment can simplify the operation mode by making the first flow rate 111, the second flow rate 121 and the third flow rate 131 equal. For example, the user does not need to adjust the flow rate of each solenoid valve, and can combine different flow rate requirements by simply opening or closing. In addition, regardless of whether the first solenoid valve 11, the second solenoid valve 12 and the third solenoid valve 13 are opened or closed, the vacuum pump 10 can maintain communication with the opening end 16 and continue to operate, so that the vacuum pump 10 will not generate negative pressure at the opening end 16 when it is opened, causing energy waste.

[0056] Figure 2 This is a system architecture diagram of the second embodiment of the negative pressure massage device 2 of the present invention. Please refer to Figure 2 As shown. The difference between the negative pressure massage device 2 of the second embodiment of the present invention and the negative pressure massage device 1 of the first embodiment is that the negative pressure massage device 2 further includes a fourth solenoid valve 14 and a cup body 161, and the control board 15 further includes a control unit 151 and a storage unit 152. The vacuum pump 10, the first solenoid valve 11, the second solenoid valve 12, the third solenoid valve 13 and the control board 15 are similar to the vacuum pump 10, the first solenoid valve 11, the second solenoid valve 12, the third solenoid valve 13 and the control board 15 of the negative pressure massage device 1 of the first embodiment, and are not described in detail here.

[0057] The fourth solenoid valve 14 is connected to the vacuum pump 10, the opening end 16, the first solenoid valve 11, the second solenoid valve 12 and the third solenoid valve 13, and is electrically connected to the control board 15. When the fourth solenoid valve 14 is opened, the air outside the negative pressure massage device 2 can flow in through the fourth solenoid valve 14, so as to adjust the pressure at the opening end 16. The amount of air flowing into the fourth solenoid valve 14 per unit time is the fourth flow rate 141, and the amount of air can be defined by volume or mass or other definitions. When the fourth solenoid valve 14 is set to a larger cross-sectional area, the fourth flow rate 141 is larger. When the fourth solenoid valve 14 is closed, the air outside the negative pressure massage device 2 cannot flow in through the fourth solenoid valve 14.

[0058] When the first solenoid valve 11, the second solenoid valve 12, the third solenoid valve 13 and the fourth solenoid valve 14 are opened at the same time, the vacuum pump 10 maintains communication with the open end 16. When the first solenoid valve 11 is opened or closed, the communication between the vacuum pump 10 and the open end 16 will not be blocked. When the second solenoid valve 12 is opened or closed, the communication between the vacuum pump 10 and the open end 16 will not be blocked. When the third solenoid valve 13 is opened or closed, the communication between the vacuum pump 10 and the open end 16 will not be blocked. When the fourth solenoid valve 14 is opened or closed, the communication between the vacuum pump 10 and the open end 16 will not be blocked. In other words, regardless of whether the first solenoid valve 11, the second solenoid valve 12, the third solenoid valve 13 and the fourth solenoid valve 14 are opened or closed, the vacuum pump 10 can maintain communication with the open end 16 and continue to operate.

[0059] The cup body 161 is connected to the open end 16, and the cup body 161 can be a three-dimensional curved surface shape, such as a hemispherical shape or a semi-ellipsoidal shape, but this is not intended to limit the present invention. The cup body 161 can be made of plastic or glass, but this is not intended to limit the present invention.

[0060] The control unit 151 may include, for example, a sensor integrated circuit, a microcontroller (MCU), a microprocessor (MPU), a central processing unit (CPU), an application-specific integrated circuit (ASIC), a digital signal processor (DSP), a graphics processing unit (GPU), a field programmable logic array (FPGA), or a system-on-chip (SoC), or other applicable chips, but they are not used to limit the present invention. The control unit 151 is electrically connected to the vacuum pump 10, the first solenoid valve 11, the second solenoid valve 12, the third solenoid valve 13, and the fourth solenoid valve 14, and can control the opening or closing of at least any one of the vacuum pump 10, the first solenoid valve 11, the second solenoid valve 12, the third solenoid valve 13, and the fourth solenoid valve 14. The storage unit 152 is electrically connected to the control unit 151, and the storage unit 152 stores control parameters. The control unit 151 opens or closes at least any one of the vacuum pump 10, the first solenoid valve 11, the second solenoid valve 12, the third solenoid valve 13, and the fourth solenoid valve 14 according to the control parameters.

[0061] In some embodiments, the first flow rate 111 , the second flow rate 121 , the third flow rate 131 , and the fourth flow rate 141 generated when the fourth solenoid valve 14 is turned on are all equal, but this is not intended to limit the present invention.

[0062] In summary, compared with the existing negative pressure massage equipment, it is difficult to optimally adapt to different parts of the human body, and it is also difficult to adapt to different massage objects, such as the elderly and children, men and women, etc. In the negative pressure massage device 2 of this embodiment, the user can first place the cup body 161 on the part to be massaged, and then turn on the main power supply of the negative pressure massage device 2. Next, the control unit 151 controls the opening of the vacuum pump 10 according to the control parameters stored in the storage unit 152, and controls the opening or closing of the first solenoid valve 11, the second solenoid valve 12, the third solenoid valve 13 and the fourth solenoid valve. The control unit 151 can control the flow rate by opening any one, any two, any three or all of the first solenoid valve 11, the second solenoid valve 12, the third solenoid valve 13 and the fourth solenoid valve 14, so as to achieve more diverse negative pressures that change with time, so as to achieve different massage effects and purposes. And solve the technical problem that it is difficult to optimally adapt the massage state of each part of the human body or the massaged object in the prior art, so as to achieve the purpose of saving costs and improving the use efficiency. Furthermore, the negative pressure massage device 2 of this embodiment can simplify the operation mode by making the first flow rate 111, the second flow rate 121, the third flow rate 131 and the fourth flow rate 141 equal. For example, the user does not need to adjust the flow rate of each solenoid valve, and can combine different flow requirements by simply opening or closing. In addition, regardless of whether the first solenoid valve 11, the second solenoid valve 12, the third solenoid valve 13 and the fourth solenoid valve 14 are opened or closed, the vacuum pump 10 can remain connected to the opening end 16 and continue to operate, so that the vacuum pump 10 will not generate negative pressure at the opening end 16 when it is opened, resulting in energy waste. Moreover, through the setting of the cup body 161, it can be adapted to the shape of the human body, making the massage process more comfortable.

[0063] Figure 3A Please refer to the control method flow chart of the negative pressure massage device of the present invention. Figure 3A As shown, step S01 is to start the vacuum pump of the negative pressure massage device. Step S02 is to generate a first negative pressure value at the opening end via the vacuum pump. Step S03 is to start the first solenoid valve of the negative pressure massage device. Step S04 is that the first solenoid valve generates a first flow and generates a second negative pressure value at the opening end. Step S05 is to start the second solenoid valve of the negative pressure massage device. Step S06 is that the second solenoid valve generates a second flow and generates a third negative pressure value at the opening end.

[0064] Please refer to Figure 1 and Figure 3AAs shown, before step S01, the user first turns on the main power of the negative pressure massage device 1, and then can control the negative pressure massage device 1 through the control panel 15 to execute steps S01 to S06. There is no absolute order for steps S01 to S06. For example, step S03 or step S05 can be executed first.

[0065] In step S01, the vacuum pump 10 of the negative pressure massage device 1 is turned on. In step S02, a first negative pressure value 101 is generated at the opening end 16 via the vacuum pump 10. When the vacuum pump 10 is turned on, the first negative pressure value 101 can be generated at the opening end 16. That is, as described above, the first negative pressure value 101 is the difference between the atmospheric pressure of the environment and the pressure at the opening end 16. When the vacuum pump 10 is turned on, the first negative pressure value 101 is a positive value. The smaller the pressure at the opening end 16, the larger the first negative pressure value 101. When the vacuum pump 10 is turned off, the pressure at the opening end 16 is the same as the atmospheric pressure of the environment. Of course, according to different definitions, the negative pressure value can also be a negative value, which is not restrictive here.

[0066] In step S03, the first solenoid valve 11 of the negative pressure massage device 1 is opened. In step S04, the first solenoid valve 11 generates a first flow rate 111 and generates a second negative pressure value 112 at the opening end 16. When the first solenoid valve 11 is opened, air (or external gas) outside the negative pressure massage device 1 can flow in through the first solenoid valve 11, thereby generating a second negative pressure value 112 at the opening end 16. That is, the amount of air flowing into the first solenoid valve 11 per unit time is the first flow rate 111. Since the inflow of air of the first flow rate 111 will cause the negative pressure value to decrease, the second negative pressure value 112 is less than the first negative pressure value 101.

[0067] In step S05, the second solenoid valve 12 of the negative pressure massage device 1 is opened. In step S06, the second solenoid valve 12 generates a second flow rate 121 and generates a third negative pressure value 122 at the opening end 16. When the second solenoid valve 12 is opened, air outside the negative pressure massage device 1 can flow in through the second solenoid valve 12, thereby adjusting the third negative pressure value 122 generated at the opening end 16. That is, the amount of air flowing into the second solenoid valve 12 per unit time is the second flow rate 121. Since the inflow of air of the second flow rate 121 will cause the negative pressure value to decrease, the third negative pressure value 122 is less than the second negative pressure value 112. In some embodiments, the first flow rate 111 is equal to the second flow rate 121.

[0068] It is worth mentioning that when the first solenoid valve 11 and the second solenoid valve 12 are opened or closed, the vacuum pump 10 is connected to the opening end 16 and the vacuum pump 10 remains in the open state. Regardless of whether the first solenoid valve 11 and the second solenoid valve 12 are opened or closed, the vacuum pump 10 can remain connected to the opening end 16 and continue to operate.

[0069] Through different combinations of the above steps, many different modes can be derived. For example, after the vacuum pump 10 is turned on for a period of time, the first solenoid valve 11 is turned on, and after a period of time, the first solenoid valve 11 is closed. In other words, the negative pressure value at the opening end 16 is changed from the first negative pressure value 101 to the second negative pressure value 112, and finally changed back to the first negative pressure value 101, that is, the negative pressure value changes from large to small and then to large.

[0070] For another example, after the vacuum pump 10 is turned on for a period of time, the first solenoid valve 11 is turned on for a period of time, the second solenoid valve 12 is turned on for a period of time, and then the first solenoid valve 11 and the second solenoid valve 12 are closed simultaneously, so that the negative pressure value at the opening end 16 changes from the first negative pressure value 101 to the second negative pressure value 112, then to the third negative pressure value 122, and then back to the first negative pressure value 101, so that the negative pressure value changes from large to small, then to a smaller value, and then to a large value. Other modes can be deduced in the same way, and will not be described in detail here.

[0071] The first negative pressure value 101 is the difference between the atmospheric pressure of the environment and the pressure at the opening end 16. When the vacuum pump 10 is turned on, the first negative pressure value 101 is a positive value. The smaller the pressure at the opening end 16 is, the greater the first negative pressure value 101 is. When the vacuum pump 10 is turned off, the pressure at the opening end 16 is the same as the atmospheric pressure of the environment.

[0072] Further, the opening time of the vacuum pump 10, the first solenoid valve 11 or the second solenoid valve 12 is greater than 0 seconds and less than or equal to 9.9 seconds. The negative pressure value generated by the vacuum pump 10 is between 40 Torr and 600 Torr. The negative pressure value is the difference between the atmospheric pressure of the environment and the pressure at the opening end 16. When the vacuum pump 10 is turned on, the negative pressure value is positive. For example, when the pressure at the opening end 16 is smaller, the negative pressure value is larger.

[0073] In the method of use described in the present invention, if the continuous activation time of the vacuum pump 10 is X, and the intermittent opening time of the first solenoid valve 11 or the second solenoid valve 12 is Y (X and Y are independent of each other on the time axis and do not affect each other), the negative pressure massage device 1 can have the following recommended implementation modes according to the part of the human body to be massaged:

[0074] (1) Chest: X = 2.0 to 2.4 seconds, Y = 0.6 to 1.0 seconds;

[0075] (2) Hip: X = 2.4 to 3.0 seconds, Y = 0.6 to 1.5 seconds;

[0076] (3) Shoulder and neck: X = 2.2-2.4 seconds, Y = 0.6-1.2 seconds or X = 2.2-2.4 seconds, Y = 0.6-1.2 seconds;

[0077] (4) Abdomen: X = 1.6 to 2.4 seconds, Y = 0.6 to 1.0 seconds;

[0078] (5) Face: X = 2.2-2.4 seconds, Y = 0.6-1.2 seconds or X = 0.1-0.2 seconds, Y = 0.1-0.2 seconds;

[0079] (6) Female private parts: X = 0.1 to 0.2 seconds, Y = 0.1 to 0.2 seconds.

[0080] Figure 3B This is a step diagram of the control method of the negative pressure massage device of the present invention, please refer to Figure 3B As shown, step S01 is to turn on the vacuum pump of the negative pressure massage device. Step S02 is to generate a first negative pressure value at the opening end via the vacuum pump. Step S03 is to turn on the first solenoid valve of the negative pressure massage device. Step S04 is that the first solenoid valve generates a first flow and generates a second negative pressure value at the opening end. Step S05 is to turn on the second solenoid valve of the negative pressure massage device. Step S06 is that the second solenoid valve generates a second flow and generates a third negative pressure value at the opening end. Step S07 is to turn on the third solenoid valve of the negative pressure massage device. Step S08 is that the third solenoid valve generates a third flow and generates a fourth negative pressure value at the opening end.

[0081] Please refer to Figure 2 and Figure 3B As shown, before step S01, the user first turns on the main power of the negative pressure massage device 2, and then can control the negative pressure massage device 2 through the control panel 15 to execute steps S01 to S08. There is no absolute order for steps S01 to S08. For example, step S03, step S05 or step S07 can be executed first.

[0082] In step S07, the third solenoid valve 13 of the negative pressure massage device 2 is opened. In step S08, the third solenoid valve 13 generates a third flow rate 131 and generates a fourth negative pressure value 132 at the opening end 16. When the third solenoid valve 13 is opened, air outside the negative pressure massage device 2 can flow in through the third solenoid valve 13, thereby generating a fourth negative pressure value 132 at the opening end 16. That is, the amount of air flowing into the third solenoid valve 13 per unit time is the third flow rate 131. Since the inflow of air of the third flow rate 131 will cause the negative pressure value to decrease, the fourth negative pressure value 132 is less than the third negative pressure value 122. In some embodiments, the first flow rate 111, the second flow rate 121 and the third flow rate 131 are all equal.

[0083] It is worth mentioning that when the first solenoid valve 11, the second solenoid valve 12 and the third solenoid valve 13 are opened or closed, the vacuum pump 10 is connected to the open end 16 and the vacuum pump 10 remains in the open state. Regardless of whether the first solenoid valve 11, the second solenoid valve 12 and the third solenoid valve 13 are opened or closed, the vacuum pump 10 can remain connected to the open end 16 and continue to operate.

[0084] Through different combinations of the above steps, many different modes can be derived. For example, after turning on the vacuum pump 10 for a period of time, the first solenoid valve 11 is turned on, after a period of time, the second solenoid valve 12 is turned on, after a period of time, the third solenoid valve 13 is turned on, after a period of time, the first solenoid valve 11, the second solenoid valve 12 and the third solenoid valve 13 are closed at the same time, and the vacuum pump 10 is turned off, so that the negative pressure value at the opening end 16 changes from the first negative pressure value 101 to the second negative pressure value 112, then to the third negative pressure value 122, then to the fourth negative pressure value 132, and then back to the first negative pressure value 101, and finally the negative pressure value is returned to zero, even if the negative pressure value changes over time. Other modes can be deduced by analogy, and will not be repeated here.

[0085] In summary, compared with the existing negative pressure massage equipment, it is difficult to optimally adapt to different parts of the human body, and it is also difficult to adapt to different massage objects, such as the elderly and children, men and women, etc. In the negative pressure massage device of the present invention and the method of use thereof, the user can first place the cup body on the part to be massaged, and then turn on the main power supply of the negative pressure massage device. Next, the control unit controls the opening of the vacuum pump according to the control parameters stored in the storage unit, and controls the opening or closing of the first solenoid valve, the second solenoid valve, the third solenoid valve 3 and the fourth solenoid valve. The storage unit can store multiple modes. The control unit can enable different modes to open or close any one, any two, any three or all of the first solenoid valve, the second solenoid valve, the third solenoid valve and the fourth solenoid valve over time to control the flow rate, so as to achieve more diverse negative pressures that change over time, so as to achieve different massage effects and purposes. And solve the technical problem that the prior art is difficult to optimally adapt to the massage state of each part of the human body or the massaged object, so as to achieve the purpose of saving costs and improving the use efficiency. Furthermore, the negative pressure massage device of this embodiment can simplify the operation mode by making the first flow rate, the second flow rate, the third flow rate and the fourth flow rate equal. For example, the user no longer needs to adjust the flow rate of each solenoid valve, and can combine different flow requirements simply by opening or closing. In addition, regardless of whether the first solenoid valve, the second solenoid valve, the third solenoid valve and the fourth solenoid valve are open or closed, the vacuum pump can remain connected to the opening end and continue to operate, so that the vacuum pump will not generate negative pressure at the opening end when it is turned on, causing energy waste. Moreover, through the setting of the cup body, it can be adapted to the shape of the human body, making the massage process more comfortable. It is also possible to select the mode that best suits the user through the multiple modes pre-stored in the storage unit, making the massage process more comfortable.
