Description

The present invention relates to personal care devices, and more particularly to mask machines.

A mask machine is a device that puts water, nutrient solution and gel chips into a chamber, heats and agitates them to uniformly mix them, discharges them, and cools and molds them to form a mask.

In the conventional mask machine, there are mainly two methods for discharging the mask liquid after heating: discharge by a mechanical button and pumping by hand. Among these methods, the manual pumping method is inconvenient to operate, and the temperature of the mask solution after heating is high, which is likely to cause burns to the user. Further, in discharging by a mechanical button, the opening and closing valve is opened and closed by operating the button to open the discharge passage, and the heated mask liquid can be automatically discharged. In this way, the consumer can operate the product for a certain period of time after starting the product during use, the discharge pipe will automatically open, the liquid will be automatically discharged into the mask tray, and can be used immediately after cooling. and there is no need to pay special attention to the working condition of the product. However, in this method, since the mask liquid solidifies after it cools, the mask liquid remaining in the discharge path adheres to the on-off valve, which prevents the on-off valve from opening normally. In the conventional mask machine, when such a situation occurs, only the forced opening and closing operation of the opening and closing valve by the motor can be handled. Further, when the on-off valve is severely clogged, the motor cannot be operated continuously for a long time, and the motor is likely to be damaged due to overheating.

The technical solution of the present invention has the following beneficial effects compared with the prior art.

1. The automatic mask making machine provided by the present invention uses a controller to control a deceleration motor to rotate a ball valve in forward and reverse directions, thereby connecting and disconnecting a stirring chamber and a mask liquid flow path, thereby allowing the mask liquid to flow into the stirring chamber. Agitation and heating are carried out by placing it inside, and the agitated mask liquid flows out to the mask tray through the mask liquid channel. Each time the ball valve rotates to the open or closed position, the microswitch sends an in-position signal to the controller, so that the time difference between the control signal output by the controller and the received in-position signal is compared. , the time for the ball valve to rotate from the open position to the closed position, or the time for the ball valve to rotate from the closed position to the open position. If the in-position signal is not received for the predetermined time or longer, it is determined that an abnormality such as clogging of the ball valve has occurred, and the controller outputs an alarm signal to stop the rotation of the deceleration motor.

2. The automatic mask making machine provided by the present invention uses a PTC heating element to heat the mask liquid, and is double protected by a temperature sensor and a temperature protector. The maximum temperature of the PTC reaches 270°C. First, the temperature sensor controls the maximum temperature for heating the mask liquid, and when the temperature sensor detects that the temperature of the mask liquid > the set value, the PTC heating element stops operating. However, if the temperature sensor element is abnormal, the temperature of the PTC will continue to rise, and when the temperature > the operating temperature of the temperature protector, the circuit of the entire device will be cut off to realize the protective action.

3. The automatic mask making machine provided by the present invention uses the attraction force of magnets to fix the cover and the mask machine body. In addition, when the mask machine body is accidentally overturned during operation, the cover and the mask machine body can be separated to prevent the liquid from jumping out. In addition, a hall switch combined with a magnet is provided in the mask machine main body so as to detect the presence or absence of the cover. As a result, the entire device can operate normally only with the cover closed, and if the cover is opened during use, warnings and Operation can be stopped.

4. The automatic mask making machine provided by the present invention is equipped with a liquid level sensor on the side wall of the stirring chamber so as to judge the height of the water level, and when the amount of injected water does not reach the set water level capacity, the working mode is Cannot start.

5. The automatic mask making machine provided by the present invention uses a Hall switch to detect whether the mask tray is placed at a predetermined position. Detects the state of the panel before starting the working mode, and if it is not in place, it cannot start. If the mask is removed during operation, when the liquid is ready to be discharged, the state of the mask tray will be detected again, and if it is not placed in place, the ball valve will not open and the liquid will be automatically discharged. However, once the mask is in place, it will automatically start draining the liquid. This prevents the liquid from automatically draining and running onto the tabletop or other areas, creating a hazard when the mask is not present. Before start-up, the signal of the microswitch is similarly detected to confirm whether or not the ball valve is in the closed position before start-up.

1 to 11, the automatic mask making machine according to this embodiment comprises a mask machine main body 1 and a mask tray 3. As shown in FIG. A stirring chamber 11 and a mask liquid flow path 12 are provided inside the mask machine main body 1, and an on-off valve is provided in a communicating portion between the stirring chamber 11 and the mask liquid flow path 12 for opening and closing the communicating portion. The mask tray 3 is for receiving the mask liquid flowing out from the mask liquid channel 12 . As a result, after heating and stirring of the mask liquid is completed, an external force is applied to the on-off valve 14 from the deceleration motor 13 to move the on-off valve 14 from the closed position to the open position, thereby opening the agitation chamber 11 and the mask liquid flow. The mask liquid after stirring and heating automatically flows from the mask liquid flow path 12 into the mask tray 3 and is provided to the user. It is possible to save the trouble of manually pumping out the mask liquid after being heated and stirred, and avoid the problem that the mask liquid hardens in the stirring chamber 11 because the pumping is not done in time.

Since activation of the deceleration motor 13 is controlled by a control signal from the controller 15, the stop of the deceleration motor 13 is realized so as to accurately stop the on-off valve 14 at the open position or the closed position. For this purpose, a first sensing unit and a second sensing unit are provided in the mask machine body 1 corresponding to the open position and the closed position, and the signal output parts of the first sensing unit and the second sensing unit are connected to the signal input of the control device 15 . Accordingly, when the on-off valve 14 moves from the open position to the closed position or from the closed position to the open position, the corresponding sensor outputs a sensor signal to the control unit 15, and the output of the control signal to the deceleration motor 13 is controlled. be stopped.

Since a large amount of mask liquid exists at the position where the on-off valve 14 exists, the on-off valve 14 is easily clogged. In this case, the on-off valve 14 cannot smoothly move to the open position or the closed position, the corresponding sensor cannot transmit a sensor signal, and the deceleration motor 13 may burn out due to long-time operation. Normally, switching between the open position and the closed position of the on-off valve 14 requires the deceleration motor 13 to operate for 1 s, but the controller 15 is set with a time threshold t (t≧1 s). When the control signal from the controller 15 causes the deceleration motor 13 to start rotating and the timing is started, and the detection signal is not received even after the time threshold t has elapsed, the controller 15 detects that the on-off valve 14 has a failure such as clogging. When it is determined that such an event has occurred, an alarm signal is output and the rotation of the deceleration motor 13 is controlled to stop. This alarm signal may be in the usual form of alarm, such as an audible alarm, an optical alarm, or the like.

In this embodiment, the first sensing unit and the second sensing unit are microswitches 16 respectively, and the on-off valve 14 is provided with a trigger member 141 for triggering the microswitches 16 . In this manner, the forward or reverse rotation of the on-off valve 14 by the deceleration motor 13 causes the trigger member 141 to come into contact with different microswitches 16 to operate the different microswitches 16 .

Specifically, the on-off valve 14 is a ball valve having a through opening 142, and when the on-off valve 14 is in the open position, the through opening 142 communicates the stirring chamber 11 and the mask liquid flow path 12, A through opening 142 offsets the agitation chamber 11 and the mask liquid channel 12 when the on-off valve 14 is in the closed position. By rotating the ball valve by 90° by the deceleration motor 13 in this manner, switching between the valve open position and the valve closed position is performed, the stroke is relatively small, and the switching speed is high.

The on-off valve 14 has a rotary shaft 143 connected to the output shaft of the speed reduction motor 13 so as to be connected to the speed reduction motor 13, and the trigger member 141 is connected to the speed reduction motor 13 and protrudes radially outward. ing. There are two trigger members 141 , which are spaced apart from each other by 90° and offset in the axial direction of the rotating shaft 143 . The microswitches 16 are installed on the PCB board, and two of them are provided at different heights corresponding to the height of the trigger member 141 . Thus, when the on-off valve 14 rotates clockwise or counterclockwise, one trigger member 141 separates from the corresponding microswitch 16 to generate a sensing signal, and the other trigger member 141 rotates, thereby It abuts on the corresponding microswitch 16 to generate a sensing signal.

Since the stirring chamber 11 is for sufficiently stirring and heating the mask solution and water, a stirring means is required inside the stirring chamber 11 . The stirring means in this embodiment uses a DC motor 111 and a magnetic stirring rotor 112 to achieve a stirring function, and the controller 15 detects the operating current value of the DC motor 111 to determine whether the function of the stirring device is normal. determine whether or not When 0.03A<operating current<0.3A, it is determined that the operation is normal, but when operating current<0.03A, it is determined that the magnetic stirring rotor 112 is not engaged, and the controller 15 outputs a warning signal. , the operating current>0.3A, it is determined that the DC motor 111 is clogged, and the controller 15 outputs a warning signal. DC motor 111 and magnetic stirring rotor 112 may be used to achieve the stirring function, so that DC motor 111 may be located outside stirring chamber 11 and magnetic stirring rotor 112 may be located inside stirring chamber 11 . rotates the magnetic stirring rotor 112 to stir the liquid in the stirring chamber 11 . After the stirring is completed, the magnetic stirring rotor 112 is removed and cleaned. In addition, since it is not necessary to provide a rotating shaft for attaching the stirring unit to the inner wall of the stirring chamber 11, the inner wall of the stirring chamber 11 can be kept flat, making cleaning easier.

In order to heat the liquid in the stirring chamber 11 , the mask machine main body 1 is provided with a PTC heating element 113 and a temperature protector 114 for heating the mask liquid in the stirring chamber 11 . The stirring chamber 11 is further provided with a temperature sensor 115 for sensing the temperature of the mask solution. As a result, the temperature sensor 115 and the temperature protector 114 are doubly protected. The maximum temperature of the PTC heating element 113 reaches 270° C. First, the temperature sensor 115 controls the maximum heating temperature of the mask liquid. Stop working. If the element of the temperature sensor 115 is abnormal, the temperature of the PTC continues to rise, and when the temperature of the PTC>the operating temperature of the temperature protector 114, the entire circuit trips and the protective action works. This provides double protection and further increases certainty and safety. In this embodiment, a thermistor (NTC) is used as the temperature sensor 115 .

In addition, a cover 2 for opening and closing the stirring chamber 11 is provided so that the user can easily put the mask liquid or water into the stirring chamber 11 . A first position sensor for detecting whether or not the cover 2 is closed is provided between the cover 2 and the mask machine main body 1 . A signal output terminal of the first position sensor is connected to a signal input terminal of the controller 15 . The first position sensor comprises a hall switch 17 provided on one of the mask machine main body 1 and the cover 2 and a magnet 21 provided on the other. The cover 2 can be fixed to the mask machine main body 1 by the attraction force of the magnet 21, and the arrangement position and the magnitude of the magnetic force of the magnet 21 facilitate the separation of the cover 2 and the mask machine main body 1. When the mask machine main body 1 is accidentally pushed and overturned, the cover 2 is not separated from the mask machine main body 1 and the liquid is prevented from jumping out. The mask machine body 1 is also provided with a Hall switch 17 for detecting the presence or absence of the cover body 2 together with the magnet 21 . As a result, the entire machine can operate normally only when the cover 2 is closed, and if the cover 2 is opened during use, the user is prevented from being scalded by the hot liquid. In addition, it is possible to issue a warning or stop the operation.

A relative position between the mask tray 3 and the mask machine body 1 is detected between the mask tray 3 and the mask machine body 1 in order to prevent the heated mask liquid from flowing into the mask tray 3 accurately. A second position sensor is provided, the signal output of the second position sensor being connected to the signal input of the controller 15 .

The second position sensor also consists of a Hall switch provided on one of the mask tray 3 and the main body 1 and a magnet provided on the other of the mask tray 3 and the main body 1 . This makes it possible to detect whether or not the mask tray 3 is correctly set using the Hall switch. Before starting the working mode, the state of the panel plate 3 is detected, if it is not put in place, it cannot be started, but if the mask 3 is removed during operation, the state of the mask 3 is again prepared for liquid discharge. is detected, and if the mask 3 is not in a predetermined position, the ball valve does not open, the liquid is not discharged, and a warning is given. This avoids the risk of liquid being automatically drained and running onto the table or other areas when the mask tray 3 is not present.

Finally, in this embodiment, a liquid level sensor 116 is provided on the side wall of the stirring chamber 11 . The liquid level sensor 116 is for judging the water level, and when the amount of supplied water does not reach the set water level capacity, the operation mode cannot be started.
