The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

Referring to fig. 1, fig. 1 is a flowchart of a control method of the negative pressure cupping device provided in the present embodiment. As shown, the method comprises the following steps:

and step S110, generating negative pressure which meets the preset requirement in the negative pressure tank.

Specifically, referring to fig. 2, the negative pressure cupping device may include: a drive part 1 and a negative pressure tank part 2. Wherein, the driving part 1 may include a housing 11, an actuating device 12, a battery (not shown in the figure), a rotation shaft 13, a transmission device 14, a can coupling plate 15, a piston disc coupling plate 16, and a physiotherapeutic module 17; the negative pressure tank part 2 may include a tank body 21, a piston 22, and a sealing ring 23. The piston 22 should be located the predetermined lowest position, namely initial position before using, actuating device 12 can include motor and control module, and control module can control the motor and rotate according to set speed and direction, drives pivot 13 rotation through transmission 14, and pivot 13 drives piston 22 up-and-down motion through piston dish binding plate 16, through changing the volume between piston 22 and skin, can change the pressure in the negative pressure jar, and then realize negative pressure physiotherapy effect.

When the user begins to use, the user selects the tank leaving mode or the tank flashing mode, and sets parameters such as pressure grade, physical therapy time, whether to heat in the tank, heating temperature and the like. After the parameters are set, the negative pressure tank is placed at the position where the tank needs to be applied, the start button is pressed, the motor drives the piston 22 to ascend, and then negative pressure is generated, and the negative pressure meets the preset requirement. It should be noted that the preset requirement may be determined according to actual needs, and this embodiment does not limit the preset requirement at all.

Step S120, the negative pressure in the negative pressure tank is made to fluctuate at a constant pressure or within a certain range.

Specifically, if the user selects the tank leaving mode, the pressure in the negative pressure tank is made constant after the negative pressure reaches a preset requirement; if the user selects the flash tank mode, the negative pressure in the negative pressure tank is fluctuated within a certain range. Wherein, the negative pressure in the negative pressure tank can fluctuate within a certain range by the repeated movement of the piston 22 driven by the motor to ascend and descend.

Step S130, after the negative pressure in the negative pressure tank is kept constant or fluctuates within a certain range for a certain time, the pressure in the negative pressure tank is reduced to stop the treatment.

Specifically, after the constant pressure in the negative pressure tank is maintained for a certain time or the negative pressure in the negative pressure tank is fluctuated for a certain time within a certain range, the motor drives the piston 22 to descend to the bottom of the tank 21 to decompress the negative pressure in the negative pressure tank, and then the treatment is stopped.

Referring to fig. 3, fig. 3 is a flowchart illustrating the process of generating the negative pressure in the negative pressure tank to meet the preset requirement according to this embodiment. As shown in the figure, the step of generating the negative pressure in the negative pressure tank to meet the preset requirement may include the following steps:

and step S310, judging whether the piston in the negative pressure tank is located at the initial position, and if so, moving the piston to generate negative pressure.

Specifically, the piston 22 should be located at a preset lowermost position, i.e., an initial position, before use, so it should be judged whether the piston 22 is located at the initial position before use. If the piston 22 is located at the initial position, the piston 22 is raised to generate a negative pressure; if the piston 22 is not located at the initial position, the piston 22 is lowered to the initial position and then the piston 22 is raised again to generate a negative pressure.

And step S320, detecting whether the negative pressure tank leaks air or not when the piston moves to the preset position, and enabling the negative pressure of the negative pressure tank to meet the preset requirement if the negative pressure tank does not leak air.

Specifically, when the piston moves to a preset position, whether the negative pressure tank leaks air or not is detected. If no air leakage occurs, the negative pressure of the negative pressure tank reaches the preset requirement; if air is leaked, the piston 22 is moved to the initial position again, and then the piston 22 is moved to the preset position until no air leakage of the negative pressure tank is detected. In specific implementation, the preset requirement may be the pressure P in the negative pressure tank₁And a predetermined pressure P₀Is smaller than a first preset value, which may be 2 KPa. It should be noted that the first preset value can be determined according to actual needs, and this embodiment is used to determine the first preset valueIt is not limited in any way.

In the embodiment, after the piston moves to the preset position, whether the negative pressure tank leaks air or not is detected, and if the negative pressure tank does not leak air, the negative pressure of the negative pressure tank meets the preset requirement; if air leaks, the piston is moved to the initial position again, and then the piston is moved to the preset position until the negative pressure tank is detected to be airtight, so that the air leakage of the negative pressure tank can be effectively avoided, and the treatment effect is ensured.

Referring to fig. 4, fig. 4 is a flowchart for detecting whether the negative pressure tank leaks air according to this embodiment. As shown, detecting whether the negative pressure tank leaks air may include the steps of:

and step S410, acquiring the pressure in the negative pressure tank when the piston moves to the preset position.

Specifically, when the piston 22 moves to a predetermined position, for example, when the piston 22 rises to a position of 10mm, the pressure in the negative pressure tank at that time is acquired by the sensor.

Step S420, calculating the Boyle constant B according to the pressure intensity₁And calculating the obtained Boyle constant B₁And a predetermined Boyle constant B₀The absolute value of the difference of (a) is compared with a second preset value.

Specifically, the Boyle constant B is calculated according to the pressure in the negative pressure tank at the moment and the Boyle's law₁I.e. according to formula B₁＝πr²hP calculation B₁Wherein r is the inner radius of the tank body, h is the rising height of the piston 22, and P is the pressure inside the tank when the piston 22 rises by the height h; and B is₁And B₀The absolute value of the difference of (a) is compared with a second preset value. It should be noted that the second preset value may be determined according to actual needs, and this embodiment does not limit the second preset value.

Step S430, if B₁And B₀If the absolute value of the difference is less than the second preset value, the negative pressure tank is airtight.

Specifically, if B₁And B₀If the absolute value of the difference is smaller than the second preset value, the negative pressure tank is airtight, and the piston 22 continues to rise until the sensor detects that the negative pressure in the tank meets the preset requirement; such asFruit B₁And B₀If the absolute value of the difference is larger than or equal to the second preset value, the negative pressure tank leaks air, and the negative pressure tank gives an alarm through sound and light to prompt a user.

In this example, B is prepared by₁And B₀The absolute value of the difference is compared with a second preset value, whether the negative pressure tank leaks air or not can be judged in advance, whether the negative pressure tank is in close contact with the skin or not can be checked, whether the operation mode of an operator is correct or not can be checked, and meanwhile, the problem that the piston does not reach the set pressure when reaching the maximum stroke can be avoided.

Referring to fig. 5, fig. 5 is a flowchart of a process of maintaining a negative pressure and a constant pressure in the negative pressure tank according to this embodiment. As shown in the figure, the process of maintaining the negative pressure constant in the negative pressure tank can comprise the following steps:

step S510, acquiring pressure P in the negative pressure tank₁And the pressure P in the negative pressure tank is adjusted₁And a predetermined pressure P₀The absolute value of the difference of (a) is compared with a first preset value.

Specifically, the mode of keeping constant pressure in the negative pressure tank is a tank retention mode, and the pressure P in the negative pressure tank is obtained through a sensor₁And the pressure P in the negative pressure tank is adjusted₁And a predetermined pressure P₀The absolute value of the difference of (a) is compared with a first preset value, which may be 2 KPa.

Step S520, if the pressure P in the negative pressure tank₁And a predetermined pressure P₀If the absolute value of the difference is smaller than the first preset value, the pressure in the negative pressure tank is kept unchanged.

In particular if the pressure P in the underpressure tank is high₁And a predetermined pressure P₀Keeping the pressure in the negative pressure tank unchanged if the absolute value of the difference is smaller than a first preset value, and after keeping for a certain time, driving the piston 22 to descend to the bottom of the tank body 21 by the motor to reduce the pressure in the negative pressure tank, and then stopping treatment; if the pressure P in the underpressure tank is high₁And a predetermined pressure P₀The absolute value of the difference is greater than or equal to a first preset value, the piston 22 is raised, and the pressure in the negative pressure tank is increased until the pressure P in the negative pressure tank is increased₁And a predetermined pressure P₀Is less thanA first preset value.

In this embodiment, in the process of maintaining the constant pressure in the negative pressure tank, the pressure in the negative pressure tank inevitably has a little leakage, and the pressure P in the negative pressure tank is obtained by changing the pressure P₁And a predetermined pressure P₀The absolute value of the difference is compared with the first preset value, if the absolute value is larger than or equal to the first preset value, the pressure in the negative pressure tank is increased until the absolute value is smaller than the first preset value, the negative pressure in the negative pressure tank can be ensured to meet the preset requirement, and the treatment effect is further ensured.

Referring to fig. 6, fig. 6 is a flowchart illustrating that the negative pressure in the negative pressure tank fluctuates within a certain range according to the present embodiment. As shown, fluctuating the negative pressure in the negative pressure tank within a certain range may include the steps of:

step S610 is to reduce the pressure in the negative pressure tank.

Specifically, the flashing mode is obtained when the negative pressure in the negative pressure tank fluctuates within a certain range, and after the negative pressure in the negative pressure tank reaches a preset requirement, the motor rotates reversely to drive the piston 22 to descend, so that the pressure in the negative pressure tank is reduced.

And step S620, when the pressure in the negative pressure tank is reduced to a third preset value, the pressure in the negative pressure tank is increased.

Specifically, when the pressure in the negative pressure tank drops to a third preset value, for example, when the pressure in the negative pressure tank drops to 10KPa, the piston 22 is raised, and thus the pressure in the negative pressure tank is raised. It should be noted that the third preset value may be determined according to actual needs, and this embodiment does not limit it at all.

And step S630, when the pressure in the negative pressure tank reaches the preset requirement, reducing the pressure in the negative pressure tank to a third preset value.

In particular, when the pressure inside the underpressure tank reaches a preset requirement, i.e. when the pressure P inside the underpressure tank reaches a preset pressure P₁And a predetermined pressure P₀When the absolute value of the difference is smaller than the first preset value, the pressure in the negative pressure tank is reduced to a third preset value; when the pressure in the negative pressure tank does not reach the preset requirement, the piston 22 is continuously raised, so that the pressure in the negative pressure tank is continuously raised,until the pressure in the negative pressure tank reaches the preset requirement.

And step S640, repeatedly reducing the pressure in the negative pressure tank, increasing the pressure in the negative pressure tank when the pressure in the negative pressure tank is reduced to a third preset value, and reducing the pressure in the negative pressure tank to the third preset value for a certain time when the pressure in the negative pressure tank reaches a preset requirement.

Specifically, the steps S610, S620 and S630 are repeated for a certain time, and then the motor drives the piston 22 to descend to the bottom of the tank 21 to reduce the pressure in the negative pressure tank, thereby stopping the treatment.

In this embodiment, through controlling the pressure in the negative pressure jar and undulant between third default and predetermineeing the requirement, can realize dodging a jar mode, and then convenient to use person operates.
