The rhythm box includes a vibration motor, and the vibration motor is used to drive the negative pressure accessories to rhythm accordingly. 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 communicate with the air hole through an external air pipe to provide suction from the external air pipe to the negative pressure air hole and form a negative pressure from the air hole to the external air 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 pulse width modulation voltage to the vibration motor through the power line. Among them, 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.

The technical content and detailed description of the present invention are as follows with reference to the drawings: Please refer to Figure 1A which is a schematic diagram of the appearance of the negative pressure massage device of the present invention. The negative pressure massage device 100 mainly suctions and releases specific parts of the body to perform uninterrupted massage to effectively relieve muscle tension and fatigue. At the same time, additional accessories (such as light therapy, heat therapy, etc.) can 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 and the accessory body 1 are provided separately. Among them, the negative pressure controller 2 is connected to the accessory body 1 through an external circuit connection. Therefore, as long as the accessory body 1 can be controlled by the negative pressure controller 2, it can operate through the connection of external circuits. In addition, Figure 1A takes two accessory bodies 1 and a negative pressure controller 2 as an example, but it is not limited to this and can be increased or decreased according to the user's needs.

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 holes 122 are used to allow air to enter/exit the negative pressure accessory 12, so that when the negative pressure accessory 12 fits a specific part of the body, a pressure change occurs. The rhythm box 14 is arranged on one side of the negative pressure fitting 12 and contacts the negative pressure fitting 12 . The accommodation space inside the rhythm box 14 includes a vibration motor, and the vibration motor is used to drive the negative pressure accessory 12 to rhythm accordingly. Specifically, when the speed of the vibration motor is increased, the vibration will be intensified, and conversely, the vibration of the vibration motor will be weakened. The negative pressure accessory 12 is affected by the intensification/weakening of the vibration of the vibration motor, producing a rhythmic effect.

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 is on the same side as the control panel 22, the negative pressure air hole 24 can be integrated on the control panel 22. The negative pressure air hole 24 is used to communicate with the air hole 122 through an external air pipe (not shown) to provide suction from the external air pipe to the negative pressure air hole 24 and form negative pressure from the accessory body 1 and the air hole 122 to the external air pipe. In contrast, the negative pressure on the accessory body 1 must When it is necessary to release, 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 thereby 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 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 first output port 26 is used to electrically connect the vibration motor inside the rhythm box 14 through the power line Pel, so as to provide the pulse width modulation voltage PWM to the vibration motor through the power line Pel.

Generally, when the pulse width modulation voltage PWM is, for example but not limited to, a high level, the vibration motor increases its rotational speed, resulting in an effect of intensified vibration. On the contrary, when the pulse width modulation voltage PWM is at a low level, the vibration motor reduces its rotational speed, thereby producing the effect of weakening the vibration. Therefore, by controlling the vibration size of the vibration motor through the pulse width modulation voltage PWM, the negative pressure 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 (for example, but not limited to, including a constant rhythm size, from large to small or from small to large), discharge frequency, etc. parameters. Therefore, the negative pressure controller 2 can adjust the duty cycle of the pulse width modulation voltage PWM, the suction force of the negative pressure air hole 24, the suction relief frequency and other operations based on the operating parameters. 1B is a schematic diagram of the correlation between the duty cycle of the pulse width modulation voltage and the rhythm intensity of the present invention. Since the rhythm intensity is positively correlated with the duty cycle (i.e., width) of the pulse width modulation voltage PWM, the negative pressure The controller 2 can adjust the duty cycle of the pulse width modulation voltage PWM based on the operating parameters to change the rhythm intensity R of the vibration motor. When the negative pressure controller 2 provides the pulse width modulation voltage PWM with a small duty ratio, the vibration intensity R of the vibration motor is small. On the contrary, when the negative pressure controller 2 provides the pulse width modulation voltage PWM with a large duty ratio, the vibration intensity R of the vibration motor is larger.

Furthermore, the negative pressure 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 encodes the level, and the voltage/current that activates the accessory body 1 is an on (ON) or off (OFF), repetitive pulse sequence to simulate a rhythmic rhythm.

Referring again to FIG. 1A , the negative pressure controller 2 further includes a housing C and a second output port 28 , and the control panel 22 includes an operation panel 222 . The casing C is used to form an accommodation space (not shown in the figure, namely inside the casing C) to house multiple components that constitute the negative pressure controller 2, which will be further introduced later. Among them, the housing C and the control panel 22 can jointly form an internal accommodation space of the negative pressure controller 2 . Alternatively, for example but not limited to, the housing C forms a separate accommodation space, and then the control panel 22 is installed through the 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 power the accessory body 1 .

Specifically, in addition to the vibration motor of the rhythm box 14 that needs to be powered, the accessory body 1 can also include additional accessories. Some of these additional accessories must be powered by an additional power supply with a fixed voltage value in order to function smoothly. operation. Therefore, the second DC voltage Vdc2 with a fixed voltage value (such as but not limited to 12V) can be provided through the second output port 28 to power additional accessories in the accessory body 1 . In addition, if the vibration motor of the rhythm box 14 continues to be powered with a high level of voltage, the vibration motor will continue to vibrate at the maximum vibration intensity. Therefore, if the vibration motor of the vibration box 14 uses the second output port 28 to provide the second DC voltage Vdc2 with a fixed voltage value, the vibration intensity R of the vibration motor can be controlled to be the maximum value (ie, 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, and other components that can be used to set operation parameters. The display interface 222B may be, for example, but not limited to, a liquid crystal, LED display, or the like with a display screen that can be viewed directly to correspondingly display the operating parameters set by the user.

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. According to these received instructions, the first output ports 26 connected to the same group on the driver board simultaneously change the specific power supply. model.

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 driving board 32 is used to control the first conversion circuit 322 to convert the first DC voltage Vdc1 into the pulse width modulation voltage PWM, so as to provide the pulse width modulation voltage PWM to the first output port 26 . At the same time, the driving board 32 is also used to control the first conversion circuit 322 to adjust the duty cycle of the pulse width modulation 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 The voltage Vdc1 is a second DC voltage Vdc2 with a fixed voltage value, so that the second DC voltage Vdc2 with a fixed voltage value is provided 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 (Inverters, or can also be called AC/DC converters). The driving 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 with a fixed voltage value, or to use a capacitor to store energy. The pulse width modulation voltage output by the second conversion circuit 324 is filtered into a second DC voltage Vdc2 with a fixed voltage value. Specifically, since multiple conversion circuits with the same circuit structure are used on the same circuit board (ie, the driving board 32 ), the conversion circuit only requires a single circuit design, and the component selection of the conversion circuit is relatively simple. Therefore, the first conversion circuit 322 and the second conversion circuit 324 are designed as the same type of converter, which can simplify the circuit design and reduce the circuit cost.
