Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
In order to better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
In order to better understand the technical scheme, the technical scheme is described in detail in the following with reference to the attached drawings of the specification and specific embodiments.
Example 1
Referring to fig. 1 to 4, the present invention discloses an intelligent trash can, which includes a can body 100, a can cover 200, a can cover motor 300 and a magnetic component.
Wherein, the magnetic component comprises a permanent magnet 400 and a first magnetic component 500. One of the permanent magnet 400 and the first magnetic attraction member 500 is disposed in the tub cover 200, and the other is disposed on the tub body 100 corresponding to an attraction position of the tub cover 200 in an open state.
That is, if the permanent magnet 400 is disposed in the tub cover 200, the first magnetic attraction member 500 is disposed on the tub 100; if the permanent magnet 400 is disposed on the tub 100, the first magnetic member 500 is disposed on the tub cover 200. And the positions of the two can correspond when the tub cover 200 is in a fully opened state to achieve adsorption.
It should be noted that the material of the first magnetic attraction member 500 of the present invention is not limited to iron, and may be other materials that can be attracted by the permanent magnet 400 in a magnetic force state.
When the barrel cover motor 300 executes a cover opening instruction, the permanent magnet electromagnet 400 is powered off at least in a tail period of the cover opening time; when the lid closing command is executed by the lid closing motor 300, the permanent magnet 400 is kept energized at least for an initial period of the lid closing time.
It is easy to understand that, in view of the design of the intelligent trash can without the position sensor and the current sampling circuit, the motor 300 of the can cover is controlled by time, that is, when the can cover is opened, the motor 300 of the can cover is turned forward for a period of time and then is closed; when closing the lid, the lid motor 300 is turned reversely for a certain period of time and then closed. The lid opening time refers to a time required for the lid motor 300 to open the lid 200, and the lid closing time refers to a time required for the lid motor 300 to close the lid 200.
The end period of the uncapping time refers to a period of time in the end period in the uncapping time process, and the length of the time can be determined according to the adsorption state of the permanent magnet 400 and the first magnetic attraction piece 500, for example, according to the time when the first magnetic attraction piece 500 enters the range of the attraction force of the permanent magnet 400. In this embodiment, the permanent magnet 400 can always maintain the power-off state during the opening process.
The initial period of the closing time is a period of time in the first period of time in the process of the closing time, and the length of the period of time can be determined according to the adsorption state between the permanent magnet 400 and the magnetic attraction piece, and the period of time in this embodiment at least ensures that the magnetic attraction piece is separated from the attraction range of the permanent magnet 400, so as to avoid influencing the closing of the barrel cover 200.
The control circuit of the intelligent garbage can cover 200 controls the permanent magnet 400, the can cover motor 300 and other executing parts to realize the functions as described above. Referring to fig. 5-8, in the present embodiment, the control circuit includes a power management circuit, a trigger circuit, a main control circuit, a first driving circuit, an indication circuit, and a second driving circuit.
Specifically, please refer to fig. 5, which illustrates a power management circuit based on the linear regulator U3, which implements a step-down from 12V to 5V to supply power to other circuits in the control circuit.
Referring to fig. 6, the main control circuit includes a main control chip U1 for generating a cover opening and closing instruction according to the cover opening and closing signal, and further controlling the first driving circuit, the indicating circuit and the second driving circuit. Specifically, the main control chip U1 has an IR-DAT pin to receive a signal to open or close the lid; the motor driving circuit is provided with INC2 pins and INC1 pins for outputting level signals to control a motor driving chip U2; there is a PWMC2 pin to control the indication circuit.
The first driving circuit is used for driving the barrel cover motor 300 and comprises a motor driving chip U2, the motor driving chip U2 is provided with a BI pin and an FI pin, and the barrel cover 200 switches the level received by the pins and can control the barrel cover motor 300. In one example, when the BI pin receives a low level and the FI pin receives a high level, the lid opening motor 300 rotates forward to perform the lid opening operation; when the BI pin receives a high level and the FI pin receives a low level, the barrel cover motor 300 rotates reversely to perform a cover closing action; when the BI pin receives a low level and the FI pin receives a low level, the tub cover motor 300 is turned off.
And the R4 and the LED1 form an indicating circuit which is used for indicating the current working state of the intelligent garbage can and executing light prompt for a certain time before executing a cover opening or closing instruction.
The trigger circuit is used for sensing a cover opening or closing signal and transmitting the signal to the main control circuit. In the present embodiment, an infrared trigger circuit is adopted, and as shown in fig. 7, the infrared trigger circuit is composed of an infrared receiving sensor U4, a capacitor C4, and an infrared tube transmitting tube IR 1. When corresponding gestures or operations block the infrared receiving sensor U4 from receiving the infrared light of the infrared transmitting tube IR1, a triggering signal for opening the cover is obtained, and otherwise, a triggering signal for closing the cover is obtained.
The second driving circuit is used for driving the permanent magnet electromagnet 400, and as shown in fig. 8, the second driving circuit includes a resistor R5, a resistor R6, a transistor Q2, and a diode D1; one end of the resistor R5 is connected with the main control chip to obtain a level signal, and the other end of the resistor R5 is connected with the base electrode of the triode Q2; the emitter of the transistor Q2 is grounded, and the resistor R6 is connected with the base and the emitter of the transistor Q2 in parallel; the collector point pole of the triode Q2 is connected with the permanent magnet electromagnet 400 in series and then is connected with VCC; the diode D1 is connected in reverse parallel with the permanent magnet 400.
In one example:
the main control chip U1 transmits 38KHZ PWM signal through IR _ OUT, when the infrared receiving sensor U4 receives 38KHZ signal, the received signal is returned to the main control chip U1 through IR _ DAT, and the LED1 lamp is fully on.
When the main control chip U1 receives the 38KHZ signal from IR _ DAT, it outputs INC2 (low level) and INC1 (high level) signals to the motor driving chip U2 to perform forward rotation, at which time the lid 200 opens, and after 2 seconds, it outputs INC2 (low level) and INC1 (low level) signals to the motor driving chip U2 to perform motor shutdown.
The output of the main control chip U1 is a low level signal output through the B _ MOTOR to turn off the transistor Q2, so that the permanent magnet electromagnet 400 is powered off and keeps magnetic property, because the trash can is close to the permanent magnet electromagnet 400 and the first magnetic attraction member 500 is installed, at this time, the trash can cover 200 is kept open and the trash can cover 200 is attracted by the magnetic property of the permanent magnet electromagnet 400, so that the trash can cover 200 does not rebound or automatically falls back.
The LED1 slowly darkens within 3 seconds after the barrel cover 200 is opened for 3 seconds, the LED1 lamp is fully lighted when the main control chip U1 receives the IR _ DAT signal, and the barrel cover 200 is automatically closed after being delayed for 3 seconds. After 3 seconds of delay, the LED1 goes out, the main control chip U1 outputs a high level signal through the B _ MOTOR to turn on the triode Q2 to enable the permanent magnet electromagnet 400 to be powered on and lose magnetism, and at the same time, the main control chip U1 outputs INC2 (high level) and INC1 (low level) signals to the MOTOR driving chip U2 to perform reversal, and at this time, the barrel cover 200 is closed, the main control chip U1 outputs a low level signal through the B _ MOTOR to enable the triode Q2 not to be opened, and after 2 seconds of delay, INC2 (low level) and INC1 (low level) signals are output to the MOTOR driving chip U2 to perform MOTOR closing, and at this time, the barrel cover 200 is closed.
Example 2
Referring to fig. 1 to 4, the present invention further provides another embodiment, which is different from embodiment 1 in that: on the basis of embodiment 1, the electromagnet 600 is additionally arranged in the magnetic attraction component, and the third driving circuit is additionally arranged in the control circuit. In addition, the permanent magnet 400 is provided in the tub cover 200.
Similarly, the electromagnet 600 is also disposed on the tub 100 corresponding to the adsorption position of the tub cover 200 in the closed state, and the electromagnets 600 and the permanent magnet electromagnets 400 repel each other magnetically.
Therefore, when the lid closing instruction is executed by the lid motor 300, the permanent magnet 400 is switched to the power-off state before the end of the lid closing time, the electromagnet 600 is powered on during the end of the lid closing time, and thus when the lid 200 is completely closed, the electromagnet 600 is powered on and generates magnetism, the permanent magnet 400 is powered off and generates magnetism, and due to the fact that the polarity of the electromagnet and the polarity of the electromagnet are opposite, the magnetism is repelled, the falling speed of the lid 200 is buffered, and phenomena of abnormal sound, wind rush (possibly causing liquid, peculiar smell and the like in the lid to drift out of the lid 100 under the action of wind pressure) and the like caused by the fact that the falling speed is too high due to the influence of the gravity of the lid 200 are avoided.
When the lid opening instruction is executed by the lid opening motor 300, the permanent magnet 400 is powered off within a period of initial time of the lid opening time, and the electromagnet 600 is powered on within a period of initial time of the lid opening time, so that the moment requirement on the starting moment of the lid opening motor 300 can be reduced and the extra load caused by the adhesion (such as possibly caused by garbage mucus) between the lid 200 and the edge of the bucket body 100 can be prevented by utilizing the repulsion of magnetism, so that the lid opening motor 300 can select smaller power, the volume is further reduced, and the service life of the lid opening motor is prolonged.
As a more preferred embodiment, the magnetically attractive assembly may further include a second magnetically attractive element 700. Similarly, the second magnetic attraction piece 700 is disposed on the barrel body 100 corresponding to the attraction position of the barrel cover 200 in the closed state, in this embodiment, the contact area between the second magnetic attraction piece 700 and the electromagnet 600 is smaller than that of the permanent magnet electromagnet 400, so that the second magnetic attraction piece 700 and the electromagnet 600 can be disposed side by side.
It is easy to understand that, in order not to affect the buffering effect generated by the magnetic force between the electromagnet 600 and the permanent magnet electromagnet 400, the attraction force between the second magnetic attraction member 700 and the permanent magnet electromagnet 400 should be smaller than the repulsion force between the electromagnet 600 and the permanent magnet electromagnet 400.
Therefore, when the electromagnet 600 and the permanent magnet electromagnet 400 are both de-energized, the permanent magnet electromagnet 400 magnetically attracts the second magnetic attraction piece 700, and on one hand, if the barrel cover 200 is not covered in place, the second magnetic attraction piece can attract the barrel cover through the attraction force; on the other hand, the garbage bin is in the non-power consumption actuation state under the normality, can prevent the accident of garbage bin and open (strong wind when like the outdoor environment), or, the rubbish of being convenient for outdoor garbage bin puts in the management (like the time quantum of district garbage bin and puts in), and the accessible of non-time quantum closes control circuit auto-lock bung 200, prevents to be opened.
The electromagnet 600 is driven by the third driving circuit, and similarly, a high level signal is output through a pin of the main control chip U1 to turn on the triode, and a low level signal turns off the triode, and the circuit principle is consistent with that of the second driving circuit, which is not described herein again.
Example 3
The invention also discloses a method for opening and closing the cover, which is used for realizing the opening and closing of the intelligent garbage can,
specifically, the implementation carrier is as shown in embodiment 1, that is, the intelligent trash can is provided with a can body 100, a can cover 200, a can cover motor 300 and a magnetic component, the magnetic component includes a permanent magnet 400 and a first magnetic component 500, one of the permanent magnet 400 and the first magnetic component 500 is disposed in the can cover 200, and the other is disposed on the can body 100 corresponding to the adsorption position of the can cover 200 in the open state.
The following method for opening and closing the cover is adopted:
when the barrel cover motor 300 executes a cover opening instruction, the permanent magnet electromagnet 400 is powered off at least in the end period of the cover opening time;
when the lid closing command is executed by the lid closing motor 300, the permanent magnet 400 is kept energized at least for an initial period of the lid closing time.
According to the method, the phenomena of abnormal falling and the like of the barrel cover 200 in the uncovering process are effectively prevented through the adsorption effect of the permanent magnet electromagnet 400 and the first magnetic attraction piece 500. The control logic is simple, the permanent magnet 400 can not act in the uncovering process, the uncovering action can be finished by triggering the barrel cover motor 300, and the barrel cover motor 300 can finish the closing action only by turning on the permanent magnet 400 for a short time in the closing process to make the magnetic force between the permanent magnet 400 and the first magnetic attraction piece 500 disappear; more importantly, based on the characteristics of the permanent magnet electromagnet 400, the intelligent garbage can is powered on only temporarily in the cover closing process, and the rest time is the power-off state, so that the low power consumption of the intelligent garbage can is ensured, and the service life of the power supply of the intelligent garbage can is not influenced basically.
In addition, as a preferred embodiment, an electromagnet 600 is additionally provided in the magnetic attraction assembly, and a permanent magnet electromagnet 400 is further provided in the tub cover 200. Similarly, the electromagnet 600 is also disposed on the tub 100 corresponding to the adsorption position of the tub cover 200 in the closed state, and the electromagnets 600 and the permanent magnet electromagnets 400 repel each other magnetically.
Then, the aforementioned method further comprises:
when the drum cover motor 300 executes a cover closing instruction, the permanent magnet electromagnet 400 is switched to a power-off state before a period of end time of the cover closing time, and the electromagnet 600 is kept powered on during the period of end time of the cover closing time.
Therefore, when the barrel cover 200 is completely closed, the electromagnet 600 is electrified to generate magnetism, the permanent magnet electromagnet 400 loses the electricity to generate magnetism, the polarity of the electromagnet and the polarity of the electromagnet are opposite, the magnetism is repelled, the falling speed of the barrel cover 200 is buffered, and phenomena of abnormal sound, wind pounding (possibly causing liquid, peculiar smell and the like in the barrel to drift out of the barrel body 100 under the action of wind pressure) and the like caused by the excessively high falling speed due to the gravity influence of the barrel cover 200 are avoided.
