Description of Related Art

The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. With the progress and development of the industrial and commercial society, in the mode of advocating speed and efficiency, modern people are always under various pressures. Coupled with abnormal diet, excessive intake of food and little exercise, many diseases related to cardiovascular or other unknown sources have occurred. In order to effectively relieve pressure and improve various functions of the body, related companies have successively developed various negative-pressure massage devices for different purposes to meet the needs of the market.

In general, the cups used in negative-pressure device in the industry will be used with a rhythm box, and the vibration generated by a vibration motor in the rhythm box will enhance blood circulation. In the known technology, a vibration intensity adjustment knob is disposed on each rhythm box, and a fixed DC power to all connected rhythm boxes is provided through a multi-connector power line. Therefore, when the vibration intensity needs to be adjusted, the knobs must be adjusted one by one on each rhythm box. Only after the device 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 individually adjust the knob to change the vibration mode, thereby causing inconvenience in use.

Accordingly, the present disclosure designs a negative-pressure massage device and a negative-pressure controller to supply power to an accessory body so that the accessory body can directly accept the current input voltage/current, without connecting to the system separately for synchronous control.

DETAILED DESCRIPTION

Reference will now be made to the drawing figures to describe the present disclosure in detail. It will be understood that the drawing figures and exemplified embodiments of present disclosure are not limited to the details thereof.

Please refer toFIG.1A, which shows a schematic appearance view of a negative-pressure massage device according to the present disclosure. The negative-pressure massage device100mainly sucks/releases specific parts of the human body for uninterrupted massage so as to effectively relieve muscle tension and fatigue. At the same time, additional accessories (such as phototherapy, heat therapy, etc.) may also be used to increase the effect of relieving muscle tension and fatigue. The negative-pressure massage device100includes at least one accessory body1and a negative-pressure controller2, and the negative-pressure controller2is separately disposed from the at least one accessory body1. In particular, the negative-pressure controller2is connected to the at least one accessory body1through an external circuit connection so as long as the accessory body1can be controlled by the negative-pressure controller2, it can be operated through the external circuit connection. In addition,FIG.1Ais an example of two accessory bodies1collocated with the negative-pressure controller2, but it is not limited thereto, and the number of the accessory bodies1may be increased or decreased according to the needs of users.

The accessory body1includes a negative-pressure accessory12and a rhythm box14. The negative-pressure accessory12includes an air hole122, and the air hole122is used to allow air to enter/exit the negative-pressure accessory12so that when the negative-pressure accessory12is attached to a specific part of the human body, pressure changes will occur. The rhythm box14is disposed and contacted on one side of the negative-pressure accessory12. A vibration motor is accommodated in an accommodating space inside the rhythm box14, and the vibration motor drives the negative-pressure accessory12to move accordingly. Specifically, when the speed of the vibration motor is increased, the vibration intensity will be intensified, otherwise the vibration intensity of the vibration motor will be weakened. The negative-pressure accessory12is affected by the intensified/weakened vibration intensity of the vibration motor to produce a rhythmic effect.

The negative-pressure controller2includes a control panel22, a negative-pressure air hole24, and a first output port26. The control panel22is disposed on one side of the negative-pressure controller2. The negative-pressure air hole24is formed on one side of the negative-pressure controller2, and may be on the same side as the control panel22or on different sides. When the negative-pressure air hole24and the control panel22are on the same side, the negative-pressure air hole24may be integrated on the control panel22. The negative-pressure air hole24communicates with the air hole122through an external air pipe (not shown) so as to provide a suction force from the external air pipe to the negative-pressure air hole24and form a negative pressure from the accessory body1and the air hole122to the external air pipe. Relatively, when the negative pressure of the accessory body1must be released, the negative-pressure controller2introduces air into the negative-pressure air hole24to release the negative pressure of the accessory body1by releasing the suction force of the negative-pressure air hole24. The first output port26is formed on one side of the negative-pressure controller2, and may be on the same side as the control panel22or on different sides. The first output port26may be integrated on the control panel22. The first output port26is electrically connected to the vibration motor inside the rhythm box14through a power linePel, and provides a PWM (pulse-width modulation) voltage PWM to the vibration motor through the power line Pe1.

In general, when the PWM 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 PWM voltage PWM is at a low level, the vibration motor decreases its rotation speed to produce an effect of weakened vibration. Therefore, by controlling the vibration intensity of the vibration motor through the PWM voltage PWM can cause the negative-pressure accessory12to produce a rhythmic effect.

Furthermore, the control panel22may be used to set operation parameters, such as but not limited to massage time, rhythm intensity (for example, but not limited to, it may include constant rhythm intensity, decreasing rhythm intensity or increasing rhythm intensity), frequency of releasing the suction force, etc. Therefore, the negative-pressure controller2can adjust the duty cycle of the PWM voltage PWM, the suction force of the negative-pressure air hole24, the frequency of releasing the suction force based on the operation parameters. Please refer toFIG.1B, which shows a schematic diagram of the correlation between the duty cycle and the rhythm intensity of the PWM voltage according to the present disclosure. Since the rhythm intensity is positively correlated with the duty ratio (i.e., the on-time width) of the PWM voltage PWM, the negative-pressure controller2may adjust the duty ratio of the PWM voltage PWM based on the operation parameters to adjust the rhythm intensity R of the vibration motor. When the negative-pressure controller2provides the PWM voltage PWM with a smaller duty ratio, the rhythm intensity R of the vibration motor is smaller. Conversely, when the negative-pressure controller2provides the PWM voltage PWM with a larger duty ratio, the rhythm intensity R of the vibration motor is larger.

Furthermore, the negative-pressure controller2acquires the required waveform equivalently by modulating the width of a series of pulses, and then uses the high-resolution counter to calculate the duty cycle of the square wave to encode the analog signal alignment bits, and the voltage/current that activates the accessory body1by an on and/or off control so that the repeated pulse sequence to simulate the rhythm.

Please refer toFIG.1Aagain, the negative-pressure controller2further includes a casing C and a second output port28, and the control panel22includes an operation panel222. The casing C forms an accommodating space inside the casing C (not shown) for accommodating multiple components constituting the negative-pressure controller2, which will be further described later. In particular, the casing C and the control panel22may commonly form the accommodating space inside the negative-pressure controller2. Alternatively, the casing C alone forms the accommodating space, and then the control panel22is installed on the casing C through an opening of the casing C. The second output port28is formed on one side of the negative-pressure controller2, and may be on the same side as the control panel22or on different sides. The second output port28may be integrated on the control panel22. The second output port28is used to output a second DC voltage Vdc2with a fixed voltage value, and the second DC voltage Vdc2may be electrically connected to the accessory body1through another power line (not shown) to supply power to the accessory body1.

Specifically, in addition to the vibration motor of the rhythm box14of the accessory body1needs to be powered, the accessory body1may also include additional accessories, which must be powered by an additional power supply with a fixed voltage value in order to operate smoothly. Therefore, the second DC voltage Vdc2(such as but not limited to 12 volts) with the fixed voltage value may be provided through the second output port28to supply power to the additional accessories in the accessory body1. In addition, if the vibration motor of the rhythm box14continues to be powered by a high-level voltage, the vibration motor will continuously vibrate at the maximum vibration intensity. Therefore, if the vibration motor of the vibration box14is changed to be powered by the second DC voltage Vdc2with the fixed voltage value through the second output port28, the vibration intensity R of the vibration motor can be controlled to the maximum vibration value (i.e., continuous vibration).

The operation panel222includes an operation interface222A and a display interface222B. The operation interface222A is, for example but not limited to, a knob, a touch screen, a switch, or other components that can be used to set operation parameters. The display interface222B may be, for example but not limited to, a liquid crystal display, an LED display, and the like with an intuitive display screen so as to correspondingly display the operation parameters set by the user.

Please refer toFIG.2A, which shows a schematic diagram of component configuration from a first perspective of internal circuits of a negative-pressure controller according to the present disclosure, and also refer toFIG.1AandFIG.1B. The negative-pressure controller2is accommodated in the accommodating space inside the casing C, and the negative-pressure controller2includes a power supply30and a driver board32, and the control panel22further includes a control board224. The power supply30is accommodated in the accommodating space, and converts an input voltage Vin into a first DC voltage Vdc. In one embodiment, the power supply30may be an AC/DC converter, and may be a power factor corrector (PFC). The driver board32is accommodated in the accommodating space, and is electrically connected to the control panel22, the first output port26, and the power supply30. The power supply30provides the first DC voltage Vdc to supply power to the driver board32, and the driver board32drives or supplies power to various components inside the negative-pressure controller2based on the control of the control panel22.

Specifically, the control board224is electrically connected to the operation panel222and the driver board32, and the control board224provides a control signal Sc corresponding to the operation parameters to the driver board32so as to control the driver board32through the control signal Sc to drive or supply power to various components inside the negative-pressure controller2. In particular, a main chip224A on the control board224is responsible for processing the instructions (i.e., operation parameters) sent by the APP or other external controllers, and according to these received instructions, the first output port26connected to the same group on the driver board32may change the specific power supply mode at the same time.

The driver board32includes a first conversion circuit322and a second conversion circuit324. The first conversion circuit322is electrically connected to the first output port26, and the second conversion circuit324is electrically connected to the second output port28. The driver board32controls the first conversion circuit322to convert the first DC voltage Vdc1into the PWM voltage PWM, and provide the PWM voltage PWM to the first output port26. The driver board32controls the first conversion circuit322to adjust the duty cycle of the PWM voltage PWM based on the control signal Sc (corresponding to the operation parameters). The driver board32controls the second conversion circuit324to convert the first DC voltage Vdc1into the second DC voltage Vdc2with the fixed voltage value so as to provide the second DC voltage Vdc2with the fixed voltage value to the second output port28.

In one embodiment, the first conversion circuit322and the second conversion circuit324are inverters, also may be called AC/DC converters. The driver board32controls the switches in the second conversion circuit324to be constantly turned on to control the second conversion circuit324to convert the first DC voltage Vdc1into the second DC voltage Vdc2with the fixed voltage value. Alternatively, a capacitor is used for energy storage to filter the PWM voltage PWM outputted by the second conversion circuit324into the second DC voltage Vdc2with the fixed voltage value. Specifically, since multiple conversion circuits with the same circuit structure are used on the same circuit board (i.e., the driver board32), the conversion circuit only needs to be designed once, and the selection of components for the conversion circuit is relatively simple. Therefore, the first conversion circuit322and the second conversion circuit324are designed as the same type of converter, which can simplify the circuit design and reduce the circuit cost.

Please refer toFIG.2B, which shows a schematic diagram of component configuration from a second perspective of internal circuits of the negative-pressure controller according to the present disclosure, and also refer toFIG.1AtoFIG.2A. The negative-pressure controller further a negative-pressure generation component34and a pressure-releasing component36. The negative-pressure generation component34is electrically connected to the driver board32, and communicates with the negative-pressure air hole24through an internal air pipe (not shown) to provide the suction force. The negative-pressure generation component34includes a vacuum pump and a driver circuit of driving the vacuum pump. The driver board32is electrically connected to the driver circuit, and controls driver circuit to drive the vacuum pump to adjust the suction force based on the control signal Sc (corresponding to the operation parameters). The vacuum pump is driven by the driver circuit for vacuum suction, and the negative-pressure air hole24provides the suction force through the internal air pipe. The pressure-releasing component36is electrically connected to the driver board32, and releases the suction force by communicating the internal air pipe (not shown) to the negative-pressure air hole24. In one embodiment, the pressure-releasing component36is an electromagnetic valve. The driver board32controls the pressure-releasing component36to release the suction force provided by the negative pressure air hole24by introducing air to generate pressure releasing during the negative-pressure process based on the control signal Sc (corresponding to the operation parameters). The driver board32controls the pressure-releasing component36to adjust a frequency of releasing the suction force based on the control signal Sc (corresponding to the operation parameters) so as to achieve intermittent suction and releasing.

Please refer toFIG.3, which shows a schematic diagram of component configuration of an accessory body according to the present disclosure, and also refer toFIG.1AtoFIG.2B. In one embodiment, the accessory body1includes a negative-pressure accessory12and a rhythm box14. A vibration motor142is installed/disposed inside the rhythm box14. The negative-pressure accessory12is a cup (the following will be represented by cup12). One end of the cup12forms a cup mouth124and the other end forms a cup bottom126away from the cup mouth124. The air hole122is communicated with the cup bottom126so that air enters/exits the cup12through the air hole122. Therefore, when the negative-pressure air hole24communicates with the air hole122through the external air pipe, and the cup12is covered on a specific part of the human body, the air in the cup12is sucked out by the suction force through the negative-pressure air hole24so that the accommodating space in the cup12can produce a negative pressure.

Please refer toFIG.3again, the cup12further includes an air-releasing valve130and an additional component132. The air-releasing valve130is disposed on the cup bottom126, and manually releases the negative pressure. Specifically, since the negative-pressure controller2operates the air suction/releasing operation based on the operation parameters, if it is urgently necessary to terminate the air suction/releasing operation, the user can manually operate the air-releasing valve130to release the negative pressure. The additional component132is disposed on the cup bottom126, and receives the second DC voltage Vdc2with the fixed voltage value to operate. Specifically, the additional component132provides an additional function of the cup12, and the additional function depends on the capabilities of the additional component132. For example, but not limited to, the additional component132may be a phototherapy module with LED lights, which is used to irradiate the direction of the cup mouth124to provide the effect of phototherapy. Alternatively, the additional component132may be a thermotherapy module with a heating body, which is used to generate heat to provide the effect of thermotherapy. Alternatively, the additional component132may be a steam module with solid/liquid atomization to generate mist into the cup12to provide the effect of steam therapy. Alternatively, the additional component132may be a negative ion emitting module that provides/emits negative ions to provide/emit negative ions that are beneficial to the human body in the direction of the cup12, and has a good regulating effect on the high-level center of the autonomic nervous system. Alternatively, a combination of the above modules. Therefore, at least one of light therapy, heat therapy, steam therapy, and negative ions can be provided to specific parts of the human body. In one embodiment, the additional component132is not limited to the above examples. For example, any additional component132that can provide additional functions of relieving muscle tension and fatigue in addition to the suction/releasing massage function should be included in the scope of this embodiment.

Accordingly, the negative-pressure massage device100developed by the present disclosure is dedicated to supply power to the connected accessory body1(especially the rhythm box14). It is known that most of the accessory body1only needs the ordinary second output port28to output a stable 12-volt voltage for operation. However, in order to provide a variety of vibration modes for the rhythm box14(such as a round-trip cycle in which the vibration body feels gradually changing from strong to weak, or directly switch between strong, medium, and weak), the present disclosure abandons the manner of synchronously controlling remote connections one by one from the accessories. Instead, the first output port26of the negative-pressure controller2provides PWM voltage PWM for regulation, and then makes the vibration motor142speed up or down so that the vibration intensity is the corresponding intensity. On the other hand, the circuit board of the accessory body1directly receives the current input voltage/current (that is, the PWM voltage PWM), and does not need to be separately connected to the system for synchronous control, which simplifies the manufacturing cost and control manner of the accessory body1.
