Detailed Description

The technical content and detailed description of the present utility model are described below with reference to the drawings:

fig. 1A is a schematic view of the negative pressure massage device according to the present utility model. The negative pressure massage device 100 is mainly used for sucking/discharging specific parts of the body to perform uninterrupted massage, so as to effectively relieve the tension and fatigue of muscles. Meanwhile, the utility model can be matched with additional accessories (such as phototherapy, thermotherapy, etc.) to increase the effect of relieving the muscle tightness and fatigue. The negative pressure massage device 100 comprises at least one fitting body 1 and a negative pressure controller 2, wherein the negative pressure controller 2 is separated from the fitting body 1. The negative pressure controller 2 is connected to the fitting body 1 by an external line, and thus the fitting body 1 can be operated by the connection of an external line as long as the negative pressure controller 2 is applicable to control. In addition, in fig. 1A, two accessory bodies 1 are matched with the negative pressure controller 2, but not limited thereto, and the number of the accessory bodies can be increased or decreased according to the needs of users.

The fitting body 1 includes a negative pressure fitting 12 and a rhythm case 14, and the negative pressure fitting 12 includes an air hole 122. The air hole 122 is used to make air enter/exit the negative pressure fitting 12, so that pressure change is generated when the negative pressure fitting 12 is attached to a specific part of the body. The rhythm case 14 is disposed on one side of the negative pressure fitting 12 and contacts the negative pressure fitting 12. The accommodating space inside the rhythm box 14 comprises a vibration motor, and the vibration motor is used for driving the negative pressure fitting 12 to vibrate accordingly. Specifically, when the rotation speed of the vibration motor is fast, the vibration aggravating effect is generated, otherwise, the vibration of the vibration motor is weakened. The negative pressure fitting 12 is affected by the acceleration/attenuation of the vibration motor, producing a rhythmic effect.

The negative pressure control device 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 control device 2. The negative pressure air hole 24 is formed on one side of the negative pressure control device 2, and may be on the same side as the control panel 22 or on a different side. The negative pressure vent 24 may be integrated on the control panel 22 when the negative pressure vent 24 is on the same side as 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 fitting body 1, the air hole 122 to the external air pipe. In contrast, when the negative pressure of the fitting body 1 must be released, the negative pressure controller 2 introduces air into the negative pressure air hole 24 to release the negative pressure of the fitting body 1 in conjunction with the suction force of the negative pressure air hole 24. The first output port 26 is disposed on one side of the negative pressure control apparatus 2, and may be the same side as the control panel 22 or different from the control panel 22, and may be integrated on the control panel 22. The first output port 26 is electrically connected to the vibration motor inside the rhythm box 14 through a power line Pe1 to provide a pulse width modulation voltage PWM to the vibration motor through the power line Pe 1.

Generally, when the PWM voltage PWM is at a high level, for example and not limited to, the vibration motor increases the rotation speed to generate a vibration-increasing effect. On the contrary, when the PWM voltage PWM is at a low level, the vibration motor decreases the rotation speed to generate the vibration attenuation effect. Therefore, the vibration of the vibration motor is controlled by the PWM voltage, so that the negative pressure fitting 12 can generate the effect of the pulsation.

Further, the control panel 22 may be used to set operating parameters such as, but not limited to, massage time, intensity of beats (e.g., but not limited to, may include constant law magnitude, from large to small or from small to large), bleeding frequency, etc. Accordingly, the negative pressure controller 2 can adjust the duty ratio of the PWM voltage PWM, the suction force of the negative pressure air hole 24, the frequency of the bleed suction force, and the like based on the operation parameters. Referring to fig. 1B, a diagram showing the correlation between the duty cycle of the PWM voltage and the intensity of the pulse, wherein the intensity of the pulse and the duty cycle (i.e. the width) of the PWM voltage PWM are positively correlated, so that the negative pressure controller 2 can adjust the duty cycle of the PWM voltage PWM based on the operation parameters to change the intensity of the pulse R of the vibration motor. When the negative pressure controller 2 supplies the pulse width modulation voltage PWM having a relatively small duty ratio, the pulse intensity R of the vibration motor is small. Conversely, when the negative pressure controller 2 supplies the PWM voltage PWM with a relatively large duty ratio, the pulse intensity R of the vibration motor is relatively large.

Further, the negative pressure controller 2 equivalently obtains a required waveform by modulating the width of a series of pulses, calculates the duty ratio of the square wave by a high resolution counter to simulate the signal alignment bit for encoding, and simulates the rhythm of the rhythm by the repeated pulse sequence with an ON (ON) or OFF (OFF) voltage/current started by the accessory body 1.

Referring back 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 configured to form a receiving space (not shown), i.e., an interior of the housing C, for accommodating a plurality of components constituting the negative pressure controller 2, which will be described later. The housing C and the control panel 22 may together form an accommodating space inside the negative pressure control device 2. Alternatively, for example, but not limited to, the housing C separately forms the accommodating space, and then the control panel 22 is installed through the opening on the housing C. The second output port 28 is disposed on one side of the negative pressure control device 2, and may be the same side as the control panel 22 or different from the control panel 22, and may be integrated on the control panel 22. The second output port 28 is configured to output a second dc voltage Vdc2 with a fixed voltage value, and the second dc voltage Vdc2 may 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 being supplied with power, the accessory body 1 may further include additional accessories, and some of the additional accessories must be supplied with power by a power source with an additional fixed voltage value, so that the accessory body 1 can operate smoothly. Accordingly, additional accessories in the accessory body 1 may be powered by a second dc voltage Vdc2 (e.g., without limitation, 12V) that provides a fixed voltage value through the second output port 28. In addition, since the vibrating motor of the rhythm case 14 is continuously supplied with a high-level voltage, the vibrating motor is continuously vibrated at the maximum vibration level. Therefore, if the second dc voltage Vdc2 with a fixed voltage value is provided to the vibration motor of the vibration box 14 instead of the second output port 28, the vibration intensity R of the vibration motor can be controlled to be the maximum value (i.e. to continuously vibrate).

The operation panel 222 includes an operation interface 222A and a display interface 222B, and the operation interface 222A may be, for example, but not limited to, a knob, a touch screen, a switch, etc. that can be used to set operation parameters. The display interface 222B may be, for example and without limitation, a display screen with visual view, such as a liquid crystal, LED display, etc., to correspondingly display the operation parameters set by the user.

Fig. 2A is a schematic diagram of the component configuration of the internal circuit of the negative pressure controller according to the present utility model at a first view angle, and fig. 1A to 1B are combined. The negative pressure control device 2 includes a power supply 30, a driving board 32, and a control panel 22 further includes a control board 224 in the accommodating space inside the casing C. The power supply 30 is accommodated in the accommodating space and is used for converting the input voltage Vin into a first direct current voltage Vdc1. The power supply 30 may be an ac/dc converter, and may be a power factor corrector (Power Factor Correction; PFC). The driving board 32 is accommodated in the accommodating 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 supplies the first direct current voltage Vdc1 to power the driving board 32, and the driving board 32 drives or supplies 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 driving board 32, and is configured to provide a control signal Sc corresponding to the operation parameter to the driving board 32, so as to control the driving board 32 to drive or supply power to each component inside the negative pressure control apparatus 2 through the control signal Sc. The control board 224 has a main chip 224A, and is responsible for processing commands (i.e., operation parameters) sent by the APP or other external controller, and according to these received commands, the first output ports 26 connected in the same group on the driving board change a specific power supply mode at the same time.

The driving board 32 includes a first converting circuit 322 and a second converting circuit 324, wherein the first converting circuit 322 is electrically connected to the first output port 26, and the second converting circuit 324 is electrically connected to the second output port 28. The driving board 32 is used for controlling the first converting circuit 322 to convert the first dc voltage Vdc1 into the PWM voltage PWM to provide the PWM voltage PWM to the first output port 26. Meanwhile, the driving board 32 is also used for controlling the first converting circuit 322 to adjust the duty ratio of the PWM voltage PWM based on the control signal Sc (corresponding to the operation parameter). The driving board 32 is also used for controlling the second converting circuit 324 to convert the first dc voltage Vdc1 into a second dc voltage Vdc2 with a fixed voltage value to provide the second dc voltage Vdc2 with the fixed voltage value to the second output port 28.

It should be noted that, in an embodiment of the present utility model, the first conversion circuit 322 and the second conversion circuit 324 may be both inverters (or may be referred to as AC/DC converters). The driving board 32 is used for controlling the switch in the second converting circuit 324 to be constantly turned on to control the second converting circuit 324 to convert the first dc voltage Vdc1 into the second dc voltage Vdc2 with a fixed voltage value, or uses a capacitor to store energy and filter the pwm voltage outputted by the second converting circuit 324 into the second dc voltage Vdc2 with a fixed voltage value. Specifically, since a plurality of conversion circuits with the same circuit structure are used on the same circuit board (i.e., the driving board 32), the conversion circuits can be designed only by a single circuit, and the components of the conversion circuits are simpler to select. Therefore, the first conversion circuit 322 and the second conversion circuit 324 are designed as the same type of converter, so as to achieve the effects of simplifying the circuit design and reducing the circuit cost.

Fig. 2B is a schematic diagram of an element configuration of the internal circuit of the negative pressure controller according to the present utility model at a second view angle, and fig. 1A to 2A are combined. The negative pressure control apparatus 2 further comprises a negative pressure generating component 34 and a pressure releasing component 36, wherein the negative pressure generating component 34 is electrically connected with the driving plate 32 and is communicated with the negative pressure air hole 24 through an internal air pipe (not shown). The negative pressure generating component 34 may include a vacuum pump and a driving circuit for driving the vacuum pump, and the driving board 32 is electrically connected to the driving circuit to control the driving circuit to drive the vacuum pump based on the control signal Sc (i.e. the operation parameter) so as to adjust the suction force. The vacuum pump is driven by the driving circuit to vacuum and the negative pressure air hole 24 provides suction force 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 via an internal air pipe (not shown). The pressure relief assembly 36 may be a solenoid valve, and the driving plate 32 is configured to control the pressure relief assembly 36 based on the control signal Sc (i.e. the operation parameter) to release the suction force provided by the negative pressure air hole 24 by introducing air to release the pressure during the negative pressure process. The driving plate 32 is used for controlling the pressure release assembly 36 to adjust the frequency of the suction released based on the control signal Sc (i.e. the operation parameter) so as to achieve intermittent suction and release.

Please refer to fig. 3, which is a schematic diagram illustrating the component configuration of the fitting body according to the present utility model, and fig. 1A-2B are repeated. In one embodiment of the present utility model, the fitting body 1 includes a negative pressure fitting 12 and a rhythm case 14, and the inside of the rhythm case 14 includes a vibration motor 142. The negative pressure fitting 12 is a cup (hereinafter, will be referred to as cup 12), but is not limited thereto. One end of cup 12 includes an open cup opening 124 and the other end includes a base 126 remote from cup opening 124. The air holes 122 are configured and communicate with the cup bottom 126 to allow air to enter/exit the cup 12 through the air holes 122. Therefore, when the negative pressure air hole 24 is communicated with the air hole 122 through the external air pipe, and the cup 12 is covered on a specific part of the body, the air in the cup is sucked out through the suction force of the negative pressure air hole 24, so that the accommodating space in the cup 12 can generate negative pressure.

Referring back to FIG. 3, cup 12 further includes a bleed valve 130 and an additional component 132. The bleed valve 130 is configured and communicates with the cup bottom 126 and is used to manually bleed negative pressure. Specifically, since the negative pressure controller 2 performs the operation of operating the air suction/discharge in accordance with the operation parameters, the user can release the negative pressure by manually operating the air release valve 130 if the operation of terminating the air suction/discharge is required urgently. The additional component 132 is disposed on the bottom 126, and the additional component 132 is operated by receiving a second dc voltage Vdc2 with a fixed voltage value through a power line (not shown). Further, the add-on component 132 is configured to provide additional functionality to the cup 12, depending on the capabilities of the add-on component 132. For example, and without limitation, the additional component 132 may be a phototherapy module having LED lights to illuminate the cup opening 124 to provide a phototherapy effect. Alternatively, the additional member 132 may be a thermal therapy module having a heating body for heating to provide a thermal therapy effect. Alternatively, the additional component 132 may be a vapor module having a solid/liquid atomizing function to create a mist into the cup 12 to provide a vapor therapy effect. Alternatively, the additional component 132 may be a negative ion emitting device with a function of providing/emitting negative ions, so as to provide/emit negative ions beneficial to human body to the direction of the cup 12, and have a good adjusting effect on the advanced central nervous system. Or a combination of the above modules. Thus, at least one of phototherapy, thermal therapy, vapor therapy, and negative ions may be provided to at least a specific part of the body. It should be noted that, in an embodiment of the present utility model, the additional component 132 is not limited to the above example. Additional components 132 that provide additional relief from muscle strain in addition to the suction/discharge massage function are included within the scope of the present embodiment.

Therefore, in summary, the negative pressure massage apparatus 100 developed in the present utility model supplies power exclusively to the connection fitting body 1 (particularly, the rhythm case 14). Most of the conventional accessory bodies 1 only need to output stable 12V through the common second output port 28, but in order to provide multiple vibration modes (such as a round-trip cycle of the vibration sense from strong to weak, or direct switching of strong, medium and weak) of the rhythm box 14, the utility model omits a mode of performing synchronous control by connecting each accessory end remotely, but the first output port 26 of the negative pressure controller 2 provides a pulse width modulation voltage to perform regulation, so that the rotation speed of the vibration motor 142 is regulated fast or slow, and the vibration strength is corresponding. On the other hand, the circuit board of the fitting body 1 directly receives the voltage/current (i.e. the PWM voltage) input at the present time, and is not connected to the system to synchronously control, thereby simplifying the manufacturing cost and control mode of the fitting body 1.
