The invention discloses a skin beauty care machine (also called 'nursing machine' for short), comprising: a host 1; a power supply (generally, a storage battery) provided in the main body 1; the skin care head 2 is arranged on the main machine 1, and the skin care head 2 at least comprises a skin cleaning channel with a skin cleaning port, a liquid supply channel and a backflow channel which are respectively communicated with the skin cleaning channel; the skin care head comprises a water purification tank 31, a waste water tank 32 and an overflow tank 4 which are detachably mounted on a host 1, wherein the water purification tank 31 is connected with a liquid supply channel of the skin care head 2 so as to send clean water in the water purification tank 31 to the liquid supply channel of the skin care head 2, the waste water tank 32 is communicated with a return channel of the skin care head 2, the waste water tank 32 is communicated with the overflow tank 4 through a third pipeline 73 by an air pump 6, air in the waste water tank 32 is pumped out by the air pump 6 so as to form negative pressure in the waste water tank 32, and waste water in the return channel of the skin care head 2 flows into the waste water tank 32 by utilizing the negative pressure; a detecting device for detecting whether the waste liquid in the waste water tank 32 enters the third pipeline 73; and the control circuit board is electrically connected with the detection device and is used for stopping the air pump 6 after the air pump 6 stops working when detecting that the waste liquid in the waste water tank 32 enters the third pipeline 73, and increasing the power of the air pump 6 to work for a preset time so as to pump the waste liquid entering the third pipeline 73 into the overflow tank 4.

Wherein, water purification case 31 and waste water case 32 are fixed and are constituteed water tank set spare 3 together, and water tank set spare 3 and overflow tank 4 are all detachably installed on host computer 1. The skin care head 2 is provided at the upper end of the main body 1, and the water tank assembly 3 and the overflow tank 4 are provided at the lower end of the main body 1. The advantage of this arrangement is that the water tank assembly 3 and the overflow tank 4 are heavy to give the machine great stability with the weight down and the weight up, and the head 2 is above for ease of use.

Wherein, the lower extreme of host computer 1 is equipped with the water tank groove, and the tank bottom in water tank groove has backup pad 11, and water tank set spare 3 detachable installs in the water tank groove. The groove wall of the water tank groove is provided with a convex limiting convex part 12, the water tank component 3 is correspondingly provided with a limiting groove 30, the supporting plate 11 is provided with an elastic buckle 13, the water tank component 3 is correspondingly provided with a buckle hole, and when the water tank component 3 is installed in the water tank groove, the limiting convex part 12 is matched with the limiting groove 30 to be connected and the elastic buckle 13 is buckled in the buckle hole. The overflow tank 4 is mounted below the support plate 11 by any one of the conventional detachable connection methods such as snap-fit, and position limitation.

Wherein, the top of the clear water tank 31 is provided with a first tank cover 311 for convenient water adding operation; a water pumping pipe 313 and an air inlet pipe 314 extending to the bottom of the purified water tank 31 are arranged in the purified water tank, the air inlet pipe 314 is communicated with the outside atmosphere, and the water pumping pipe 313 is connected with the liquid supply channel through a first pipeline 71. The top of waste tank 32 has a second tank cap 321 to facilitate the dumping of waste liquid. The waste water tank 32 is communicated with the return channel of the skin care head 2 through a second pipeline 72. The overflow tank 4 is provided with an intake port 41 connected to the third duct 73 and an exhaust port 42 communicating with the outside atmosphere. Therefore, the air pump 6 operates to pump air in the waste water tank 32 into the overflow tank 4 and is discharged through the air outlet 42.

In one embodiment, the skin care head 2 is in the skin cleaning device of CN2019101861212, and will not be repeated here. Of course, the skin care head 2 may have other structures or functions in the prior art, which are not described in detail herein.

Again as shown in connection with fig. 5. The control circuit board is provided with a controller U1, a state detection switch and an air pump driving circuit for driving the air pump 6 to work. The controller U1 is generally implemented by a single chip microcomputer, such as a single chip microcomputer of AT89C51, wherein the first control port P2.0 of the controller U1 is electrically connected to the air pump driving circuit to control the operating state and thus the operating power of the air pump 6. The air pump driving circuit is prior art, for example, the air pump driving circuit includes a transistor and a relay, the relay is electrically connected between the air pump 6 and the power supply, the transistor is used as a driving switch of the relay, wherein, the base of the transistor is electrically connected with the P2.0 port of the controller U1, thus, the P2.0 port of the controller U1 outputs a control signal to control the action of the transistor, so as to change the working state of the air pump 6, for example, the control signal is a PWM signal, and the power of the air pump 6 can be changed at different duty ratios, which is not described in detail herein.

The power supply supplies power to the air pump 6 through the state detection switch. The state detection switch is a balance switch or an angle switch. The common balance switch is a mercury balance switch or a ball balance switch, and the common angle switch is also a mercury angle switch or a ball angle switch. Since the state detection switch is provided on the control circuit board, the control circuit board can be horizontally installed in the main body 1. Therefore, when a user (or a user) holds the handheld body 1 to use the nursing machine, the nursing machine can certainly incline the water tank assembly 3 according to the use requirement, when the inclination angle of the water tank assembly 3 does not exceed the preset angle, the wastewater in the wastewater tank 32 can not enter the third pipeline 73, at the moment, the nursing machine can work normally, and therefore the balance switch or the angle switch is also in a conducting state, and the air pump 6 can work normally; on the contrary, when the inclination angle of the nursing machine exceeds the preset angle, the balance switch or the angle switch is also in a disconnected state, so that the air pump 6 is powered off, and the nursing machine stops working.

In addition, the controller U1 can also detect whether the orientation state of the nursing machine is normal, that is, whether the inclination angle of the nursing machine is within the preset angle, and the implementation manner is as follows: one end of the state detection switch is electrically connected to the series resistor R2 and the second detection port P1.1 of the controller U1. Therefore, when the orientation state of the nursing machine is normal and the inclination angle corresponding to the nursing machine is within the preset angle, the state detection switch is turned on, and at this time, the second detection port P1.1 of the controller U1 is at a high level; on the contrary, when the orientation state of the nursing machine is abnormal, the state detection switch is turned off when the inclination angle exceeds the preset angle due to the rollover of the nursing machine or improper use, and the like, at this time, the second detection port P1.1 of the controller U1 is at a low level. Therefore, the controller U1 can determine whether the orientation state of the nursing machine is normal according to the level of the second detection port P1.1.

Furthermore, the detecting device comprises a first probe J1 and a second probe J2 which are arranged in a third pipeline 73 communicating the waste water tank 32 and the air pump 6, the first probe J1 and the second probe J2 are arranged at intervals so that the first probe J1 and the second probe J2 are not directly electrically communicated, the first probe J1 is connected with a direct current power supply VCC (general VCC is 5V) through a resistor R1, and the second probe J2 is electrically connected with a first detecting port P1.0 of a controller U1 on a control circuit board. Therefore, when the waste liquid collected from the skin care head 2 in the waste water tank 32 does not enter the third pipeline 73, the first probe J1 is not electrically connected with the second probe J2, so that the first detection port P1.0 of the controller U1 detects a low level; on the contrary, when the nursing machine is toppled or the user holds the main unit 1 to incline the nursing machine by a larger angle, the waste liquid in the waste water tank 32 enters the third pipeline 73 carelessly, the waste liquid is filled between the first probe J1 and the second probe J2, so that the first probe J1 is electrically connected with the second probe J2, and the first detection port P1.0 of the controller U1 detects a high level. Therefore, the controller U1 on the control circuit board can detect and determine whether the waste liquid in the waste water tank 32 enters the third pipeline 73 through the level signal of the first detection port P1.0.

As further shown in fig. 6, the skin beauty treatment machine works as follows:

in step S1, after the nursing machine is turned on, the air pump 6 is started to operate.

Specifically, the waste water tank 32 forms a larger negative pressure under the action of the air pump 6, and the larger negative pressure in the waste water tank 32 generates a negative pressure suction force on the return channel of the skin care head 2 through the second pipeline 72; meanwhile, the skin cleaning port of the skin care head 2 is attached to the skin and is sealed by the skin, so that negative pressure is transmitted to the liquid supply channel through the skin cleaning port, clean water in the water purification tank 31 is sent to the liquid supply channel of the skin care head 2 through the first pipeline 71 under the action of the negative pressure, and the clean water is sprayed out through the skin care port in the modes of ultrasonic water columns, water mist and the like under the action of the skin care head 2; waste liquid generated in the skin cleaning and nursing process flows back to the return channel of the skin care head 2 under the action of negative pressure, and then the waste liquid in the return channel flows into the waste water tank 32 under the action of negative pressure, so that water drops generated after the oxygen-enriched water is used for performing beauty treatment on the skin in the using process are prevented from dropping.

Step S2, it is determined whether or not waste liquid has entered the third pipe 73. As described above, the controller U1 on the control circuit board can detect and determine whether the waste liquid in the waste water tank 32 enters the third pipeline 73 through the level signal of the first detection port P1.0. If the waste liquid in the waste water tank 32 is judged not to enter the third pipeline 73, the step returns to the step S2 to continue the detection, otherwise, the step returns to the step S3.

Step S3 is to stop the operation of the air pump 6. As described above, the first control port P2.0 of the controller U1 generates a control signal to the air pump driving circuit to change the operation state of the air pump 6, including starting/stopping the operation of the air pump 6 or changing the operation power of the air pump 6, respectively, which will not be described in detail herein.

And S4, detecting whether the orientation state of the nursing machine is normal, if not, sending a prompt message to prompt a user to restore the normal orientation state of the nursing machine, returning to S4 to continue the detection, otherwise, turning to S5 when the orientation state of the nursing machine is normal. As described above, the controller U1 can determine whether the orientation state of the nursing machine is normal according to the level of the second detection port P1.1.

Step S5, the controller U1 controls the air pump 6 to be started, and the air pump 6 is operated at increased power for a preset time period to pump the waste liquid entering the third pipeline 73 into the overflow tank 4, and then the operation returns to step S1 to allow the nursing machine to continue to operate normally, and the waste water tank 32 maintains a negative pressure state to ensure that the waste liquid generated by the skin care head 2 can be continuously sucked into the waste water tank 32 by using the negative pressure, so as to avoid the waste liquid generated by the skin care head 2 from dripping or splashing to affect the use experience of the user. The purpose of starting the air pump 6 and operating the air pump 6 with increased power for a preset time period can be achieved by the first control port P2.0 of the controller U1 generating a corresponding control signal to the air pump driving circuit, which is common knowledge of those skilled in the art and will not be described in detail.

In summary, the skin beauty care machine disclosed by the invention utilizes the air pump 6 to generate negative pressure to the waste water tank 32 to recycle the waste liquid generated by the skin care head 2, even if the nursing machine is toppled or improperly used in the using process, so that the orientation state of the nursing machine is abnormal, the waste liquid in the waste water tank 32 carelessly enters the third pipeline 73, and the negative pressure is possibly disappeared or weakened, under the condition that the orientation state of the nursing machine is judged to be recovered to be normal, let air pump 6 increase power take out the waste liquid that gets into in the third pipeline 73 in the overflow case 4, both avoided the waste liquid that collects in the waste water tank 32 to take place the hourglass, guaranteed again that the negative pressure disappearance can not appear in the nursing machine course of working or weaken and lead to the waste liquid that skin care head 2 produced can't in time flow waste water tank 32 and produce the condition that drips or splash to the operational reliability of nursing machine has been improved and is favorable to improving user's use and experiences.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
