Description

Negative pressure massage device and negative pressure controller

The present invention relates to a massage device and a controller, and in particular to a negative pressure massage device and a negative pressure controller.

With the progress and development of the industrial and commercial society, in the mode of advocating speed and efficiency, modern people always bear various pressures. Coupled with abnormal diet, excessive food intake and little exercise, many cardiovascular-related or other unknown diseases have arisen. In order to effectively relieve stress and improve various functions of the body, relevant industries have successively developed various negative pressure massage equipment for different purposes to meet the needs of the market.

The cups used in general negative pressure instruments in the industry are used with a rhythm box, and the motor vibration inside the rhythm box enhances blood circulation. In the known technology, each rhythm box has a vibration intensity adjustment knob, and the instrument will provide a DC power of a fixed voltage value to all connected rhythm boxes through a multi-connector power cord. Therefore, when the vibration intensity needs to be adjusted, the knob must be adjusted one by one on each rhythm box. Only after the instrument counts down for 30 minutes will the DC power be cut off once, so that all rhythm boxes will stop operating at the same time. Therefore, each rhythm box must adjust the knob separately to change the vibration mode, causing inconvenience in use.

Therefore, how to design a negative pressure massage device and a negative pressure controller to supply power to the accessory body so that the accessory body can directly receive the current input voltage/current without being connected to the system for synchronous control is a major topic that the creator of this case wants to study.

In order to solve the above problems, the present invention provides a negative pressure massage device to overcome the problems of the prior art. Therefore, the negative pressure massage device of the present invention includes at least one accessory body and a negative pressure controller, and the negative pressure controller is separately arranged from the accessory body. The accessory body includes a negative pressure accessory and a rhythm box, and the negative pressure controller includes a control panel, a negative pressure air hole and a first output port. The negative pressure accessory includes an air hole, and the rhythm box is arranged on one side of the negative pressure accessory and contacts the negative pressure accessory. The rhythm box includes a vibration motor, and the vibration motor is used to drive the negative pressure accessory to rhythmically move. The control panel is arranged on one side of the negative pressure controller and is used to set operating parameters. The negative pressure air hole is opened on one side of the negative pressure controller and is used to connect the air hole through an external air supply pipe to provide suction from the external air supply pipe to the negative pressure air hole and form a negative pressure from the air hole to the external air supply pipe. The first output port is opened on one side of the negative pressure controller and is used to electrically connect the rhythm box through the power line to provide the pulse width modulation voltage to the vibration motor through the power line. The negative pressure controller adjusts the duty cycle of the pulse width modulation voltage based on the operating parameters to change the rhythm intensity of the vibration motor based on the adjustment of the duty cycle.

In order to solve the above problems, the present invention provides a negative pressure controller to overcome the problems of the prior art. Therefore, the negative pressure controller of the present invention is used to control and adjust the negative pressure and rhythm intensity generated by at least one accessory body, and the negative pressure controller includes a control panel, a negative pressure air hole and a first output port. The control panel is arranged on one side of the negative pressure controller and is used to set the operating parameters. The negative pressure air hole is opened on one side of the negative pressure controller and is used to provide suction from the outside to the negative pressure air hole. The first output port is opened on one side of the negative pressure controller and is used to provide a pulse width modulation voltage. Among them, the negative pressure controller adjusts the duty cycle of the pulse width modulation voltage based on the operating parameters, and the size of the duty cycle is positively correlated with the rhythm intensity. Among them, the size of the suction force is positively correlated with the negative pressure.

The main purpose and effect of the present invention is that the negative pressure massage device developed by the present invention is dedicated to supplying power to the accessory body (especially the rhythm box), and the first output port of the negative pressure controller provides a pulse width modulated voltage for regulation, thereby speeding up or slowing down the vibration motor so that the vibration intensity is the corresponding intensity. On the other hand, the circuit board of the accessory body directly receives the current input voltage/current (i.e., pulse width modulated voltage), and does not need to be connected to the system separately for synchronous control, which simplifies the manufacturing cost and control method of the accessory body.

In order to further understand the technology, means and effects adopted by the present invention to achieve the intended purpose, please refer to the following detailed description and drawings of the present invention. It is believed that the purpose, features and characteristics of the present invention can be understood in depth and in detail. However, the attached drawings are only provided for reference and explanation, and are not used to limit the present invention.

The technical content and detailed description of the present invention are as follows with accompanying drawings:

Please refer to FIG. 1A for a schematic diagram of the negative pressure massage device of the present invention. The negative pressure massage device 100 mainly performs suction/release on specific parts of the body to perform continuous massage to effectively relieve muscle tension and fatigue. At the same time, additional accessories (such as light therapy, heat therapy, etc.) can also be used to increase the effect of relieving muscle tension and fatigue. The negative pressure massage device 100 includes at least one accessory body 1 and a negative pressure controller 2, and the negative pressure controller 2 is separated from the accessory body 1. The negative pressure controller 2 is connected to the accessory body 1 by an external line connection, so any accessory body 1 that can be controlled by the negative pressure controller 2 can be operated by the external line connection. In addition, FIG. 1A takes two accessory bodies 1 and a negative pressure controller 2 as an example, but it is not limited to this, and it can be increased or decreased according to the needs of the user.

The accessory body 1 includes a negative pressure accessory 12 and a rhythm box 14, and the negative pressure accessory 12 includes an air hole 122. The air hole 122 is used to allow air to enter/exit the negative pressure accessory 12, so that when the negative pressure accessory 12 is attached to a specific part of the body, a change in pressure is generated. The rhythm box 14 is configured on one side of the negative pressure accessory 12 and contacts the negative pressure accessory 12. The accommodating space inside the rhythm box 14 includes a vibration motor, and the vibration motor is used to drive the negative pressure accessory 12 to vibrate accordingly. Specifically, when the speed of the vibration motor is increased, an intensified vibration effect will be generated, and vice versa, the vibration of the vibration motor will be weakened. The negative pressure accessory 12 is affected by the intensified/weakened vibration of the vibration motor, and a rhythmic effect is generated.

The negative pressure controller 2 includes a control panel 22, a negative pressure air hole 24 and a first output port 26, and the control panel 22 is disposed on one side of the negative pressure controller 2. The negative pressure air hole 24 is opened on one side of the negative pressure controller 2, and can be on the same side as the control panel 22 or on a different side. When the negative pressure air hole 24 and the control panel 22 are on the same side, the negative pressure air hole 24 can be integrated on the control panel 22. The negative pressure air hole 24 is used to connect the air hole 122 through an external air supply pipe (not shown) to provide suction from the external air supply pipe to the negative pressure air hole 24, and form a negative pressure from the accessory body 1, the air hole 122 to the external air supply pipe. In contrast, when the negative pressure of the accessory body 1 must be released, the negative pressure controller 2 introduces air into the negative pressure air hole 24 to release the suction of the negative pressure air hole 24 and release the negative pressure of the accessory body 1. The first output port 26 is opened on one side of the negative pressure controller 2, and can be on the same side or different side as the control panel 22, and can be integrated on the control panel 22. The first output port 26 is used to electrically connect to the vibration motor inside the rhythm box 14 through the power line Pe1 to provide a pulse width modulation voltage PWM to the vibration motor through the power line Pe1.

Generally, when the pulse width modulated voltage PWM is, for example but not limited to, at a high level, the vibration motor increases its rotation speed to produce an effect of intensified vibration. Conversely, when the pulse width modulated voltage PWM is at a low level, the vibration motor decreases its rotation speed to produce an effect of reduced vibration. Therefore, by controlling the vibration magnitude of the vibration motor through the pulse width modulated voltage PWM, the negative voltage accessory 12 can produce a rhythmic effect.

Furthermore, the control panel 22 can be used to set operating parameters, such as but not limited to massage time, rhythm intensity (such as but not limited to constant rhythm size, from large to small or from small to large), discharge frequency, etc. Therefore, the negative pressure controller 2 can adjust the duty cycle of the pulse width modulation voltage PWM, the suction of the negative pressure vent 24, the discharge suction frequency, etc. based on the operating parameters. Referring to FIG. 1B , which is a schematic diagram of the correlation between the duty cycle of the pulse width modulated voltage and the rhythm intensity of the present invention, since the rhythm intensity is positively correlated with the duty cycle (i.e., the width) of the pulse width modulated voltage PWM, the negative voltage controller 2 can adjust the duty cycle of the pulse width modulated voltage PWM based on the operating parameters to change the rhythm intensity R of the vibration motor. When the negative voltage controller 2 provides a pulse width modulated voltage PWM with a smaller duty cycle, the rhythm intensity R of the vibration motor is smaller. On the contrary, when the negative voltage controller 2 provides a pulse width modulated voltage PWM with a larger duty cycle, the rhythm intensity R of the vibration motor is larger.

Furthermore, the negative voltage controller 2 modulates the width of a series of pulses to obtain the required waveform, and then uses a high-resolution counter to calculate the duty cycle of the square wave to simulate the signal alignment bit for encoding, so that the voltage/current that activates the accessory body 1 is an on (ON) or off (OFF) repeated pulse sequence to simulate a rhythmic rhythm.

Referring again to FIG. 1A , the negative pressure controller 2 further includes a housing C, a second output port 28 , and the control panel 22 includes an operation panel 222 . The housing C is used to form a storage space (not shown, i.e., inside the housing C) to accommodate a plurality of components constituting the negative pressure controller 2 , which will be further described later. Among them, the housing C and the control panel 22 can form a storage space inside the negative pressure controller 2 . Alternatively, for example but not limited to, the housing C alone forms a storage space, and the control panel 22 is then installed through an opening on the housing C. The second output port 28 is opened on one side of the negative pressure controller 2 , and can also be on the same side as the control panel 22 or on a different side, and can be integrated on the control panel 22 . The second output port 28 is used to output a second DC voltage Vdc2 with a fixed voltage value, and the second DC voltage Vdc2 can be electrically connected to the accessory body 1 through another power line (not shown) to supply power to the accessory body 1.

Specifically, in addition to the vibration motor of the rhythm box 14, the accessory body 1 may also include additional accessories. Some of these additional accessories must be powered by an additional fixed voltage value power source to operate smoothly. Therefore, the second output port 28 can provide a second DC voltage Vdc2 with a fixed voltage value (for example, but not limited to 12V) to power the additional accessories in the accessory body 1. In addition, if the vibration motor of the rhythm box 14 is continuously powered by a high-level voltage, the vibration motor will continue to vibrate at the maximum vibration intensity. Therefore, if the vibration motor of the rhythm box 14 is changed to provide a second DC voltage Vdc2 with a fixed voltage value through the second output port 28, the rhythm intensity R of the vibration motor can be controlled to be the maximum value (i.e., continuous vibration).

The operation panel 222 includes an operation interface 222A and a display interface 222B. The operation interface 222A may be, for example but not limited to, a knob, a touch screen, a switch, or other components for setting operation parameters. The display interface 222B may be, for example but not limited to, a liquid crystal, an LED display, or other display screen that can be viewed visually to display the operation parameters set by the user accordingly.

Please refer to FIG. 2A for a schematic diagram of the component configuration of the internal circuit of the negative voltage controller of the present invention from a first perspective, and refer to FIG. 1A to FIG. 1B in conjunction. The negative voltage controller 2 includes a power supply 30 and a driver board 32 in the accommodation space inside the housing C, and the control panel 22 also includes a control board 224. The power supply 30 is accommodated in the accommodation space and is used to convert the input voltage Vin into a first DC voltage Vdc1. The power supply 30 can be an AC/DC converter and can be a power factor corrector (Power Factor Correction; PFC). The driver board 32 is accommodated in the accommodation space and is electrically connected to the control panel 22, the first output port 26, the second output port 28 and the power supply 30. The power supply 30 provides a first DC voltage Vdc1 to power the driver board 32 , and the driver board 32 drives or powers various components inside the negative pressure controller 2 based on the control of the control panel 22 .

Specifically, the control board 224 is electrically connected to the operation panel 222 and the driver board 32, and is used to provide a control signal Sc corresponding to the operating parameter to the driver board 32, so as to control the driver board 32 to drive or supply power to various components inside the negative pressure controller 2 through the control signal Sc. Among them, there is a main chip 224A on the control board 224, which is responsible for processing the instructions (i.e., operating parameters) sent by the APP or other external controllers, and according to these received instructions, the first output ports 26 connected in the same group on the driver board are simultaneously changed to a specific power supply mode.

The driver board 32 includes a first conversion circuit 322 and a second conversion circuit 324, wherein the first conversion circuit 322 is electrically connected to the first output port 26, and the second conversion circuit 324 is electrically connected to the second output port 28. The driver board 32 is used to control the first conversion circuit 322 to convert the first DC voltage Vdc1 into a pulse width modulated voltage PWM, so as to provide the pulse width modulated voltage PWM to the first output port 26. At the same time, the driver board 32 is also used to control the first conversion circuit 322 to adjust the duty cycle of the pulse width modulated voltage PWM based on the control signal Sc (corresponding to the operating parameter). The driving board 32 is also used to control the second conversion circuit 324 to convert the first DC voltage Vdc1 into a second DC voltage Vdc2 with a fixed voltage value, so as to provide the second DC voltage Vdc2 with a fixed voltage value to the second output port 28.

It is worth mentioning that in one embodiment of the present invention, the first conversion circuit 322 and the second conversion circuit 324 can both be inverters (or AC/DC converters). The driver board 32 is used to control the switch in the second conversion circuit 324 to be constantly turned on to control the second conversion circuit 324 to convert the first DC voltage Vdc1 into a second DC voltage Vdc2 of a fixed voltage value, or to use a capacitor for energy storage to filter the pulse width modulated voltage output by the second conversion circuit 324 into a second DC voltage Vdc2 of a fixed voltage value. Specifically, since multiple conversion circuits with the same circuit structure are used on the same circuit board (i.e., the driver board 32), the conversion circuit only needs to be designed once, and the selection of components for the conversion circuit is also relatively simple. Therefore, the first conversion circuit 322 and the second conversion circuit 324 are designed as the same type of converter, which can achieve the effect of simplifying the circuit design and reducing the circuit cost.

Please refer to FIG. 2B for a second perspective diagram of the internal circuit of the negative pressure controller of the present invention, and refer to FIG. 1A to FIG. 2A in conjunction. The negative pressure controller 2 further includes a negative pressure generating assembly 34 and a pressure relief assembly 36. The negative pressure generating assembly 34 is electrically connected to the driving plate 32 and is connected to the negative pressure air hole 24 through an internal air pipe (not shown). The negative pressure generating assembly 34 may include a vacuum pump and a driving circuit for driving the vacuum pump, and the driving plate 32 is electrically connected to the driving circuit to control the driving circuit based on the control signal Sc (i.e., the operating parameter) to drive the vacuum pump and adjust the strength of the suction. The vacuum pump is driven by the driving circuit to vacuum and provide suction to the negative pressure air hole 24 through the internal air pipe. The pressure relief assembly 36 is electrically connected to the driving plate 32 and is connected to the negative pressure air hole 24 through the internal air pipe (not shown). The pressure relief assembly 36 can be an electromagnetic valve, and the driving plate 32 is used to control the pressure relief assembly 36 based on the control signal Sc (i.e., the operating parameter) to release the suction provided by the negative pressure air hole 24 by introducing air to generate pressure relief during the negative pressure process. Among them, the driving plate 32 is used to control the pressure relief assembly 36 based on the control signal Sc (i.e., the operating parameter) to adjust the frequency of suction being released to achieve intermittent suction and release.

Please refer to FIG. 3 for a schematic diagram of the component configuration of the accessory body of the present invention, and refer to FIG. 1A to FIG. 2B in conjunction. In one embodiment of the present invention, the accessory body 1 includes a negative pressure accessory 12 and a rhythm box 14, and the rhythm box 14 includes a vibration motor 142 inside. The negative pressure accessory 12 is a cup (hereinafter referred to as the cup 12), but is not limited thereto. One end of the cup 12 includes an open cup mouth 124, and the other end includes a cup bottom 126 away from the cup mouth 124. The air hole 122 is configured and connected to the cup bottom 126, so that air can enter/exit the cup 12 through the air hole 122. Therefore, when the negative pressure air hole 24 is connected to the air hole 122 through the external air supply tube and the cup 12 is placed on a specific part of the body, the air in the cup is sucked out by the suction force of the negative pressure air hole 24, so that negative pressure is generated in the accommodation space of the cup 12.

Referring again to FIG. 3 , the cup 12 further includes a relief valve 130 and an additional component 132. The relief valve 130 is disposed and connected to the cup bottom 126 and is used to manually release the negative pressure. Specifically, since the negative pressure controller 2 operates the air suction/release operation according to the operating parameters, if the air suction/release operation needs to be terminated urgently, the user can release the negative pressure by manually operating the relief valve 130. The additional component 132 is disposed at the cup bottom 126, and the additional component 132 operates by receiving a second DC voltage Vdc2 of a fixed voltage value through a power line (not shown). Furthermore, the additional component 132 is used to provide the cup 12 with additional functions, and the additional functions are determined according to the capabilities of the additional component 132. For example, but not limited to, the additional component 132 can be a light therapy module with an LED lamp, which is used to irradiate the cup mouth 124 to provide a light therapy effect. Alternatively, the additional component 132 can be a heat therapy module with a heating element, which is used to generate heat to provide a heat therapy effect. Alternatively, the additional component 132 can be a steam module with atomization of solid/liquid, which is used to generate mist into the cup 12 to provide a steam therapy effect. Alternatively, the additional component 132 can be a negative ion emitting device that provides/emits negative ions, which is used to provide/emits negative ions that are beneficial to the human body in the direction of the cup 12, and has a good regulating effect on the higher autonomic nervous center. Or it can be a combination of the above modules. Therefore, at least one of light therapy, heat therapy, steam therapy and negative ions can be provided to a specific part of the body. It is worth mentioning that in one embodiment of the present invention, the additional component 132 is not limited to the above-mentioned examples. Any additional component 132 that can provide additional functions of relieving muscle tension and fatigue in addition to the suction/release massage function should be included in the scope of this embodiment.

Therefore, in summary, the negative pressure massage device 100 developed by the present invention is specifically used to supply power to the connected accessory body 1 (especially the rhythm box 14). It is known that most accessory bodies 1 only need the general second output port 28 to output a stable 12V to operate, but in order to provide the rhythm box 14 with multiple vibration modes (such as the vibration sensation changing from strong to weak back and forth, or directly switching between strong, medium, and weak), the present invention abandons the method of remote connection from the accessory end for synchronous control, but instead provides a pulse width modulation voltage from the first output port 26 of the negative voltage controller 2 for regulation, thereby allowing the vibration motor 142 to speed up or slow down, so that the vibration intensity is the corresponding intensity. On the other hand, the circuit board of the accessory body 1 directly receives the current input voltage/current (i.e., pulse width modulation voltage PWM) without being separately connected to the system for synchronous control, thereby simplifying the manufacturing cost and control method of the accessory body 1.
