Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
In order that the above-described aspects may be better understood, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may 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 above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.
Example 1
Referring to fig. 1 to 4, the invention discloses an intelligent garbage can, which comprises a can body 100, a can cover 200, a can cover motor 300 and a magnetic component.
The magnetic attraction assembly comprises a permanent magnet electromagnet 400 and a first magnetic attraction piece 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 opened state.
That is, if the permanent magnet electromagnet 400 is disposed in the tub cover 200, the first magnetic attraction 500 is disposed on the tub body 100; when the permanent magnet 400 is disposed on the tub 100, the first magnetic attraction member 500 is disposed on the tub cover 200. And the positions of the two can be corresponding when the tub cover 200 is in a completely opened state, so as to realize adsorption.
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 electromagnet 400 in a magnetic state.
When the lid motor 300 executes the lid opening command, the permanent magnet electromagnet 400 is kept powered off at least for the last period of the lid opening time; when the cap motor 300 executes a cap closing command, the permanent magnet electromagnet 400 remains energized for at least a portion of the initial time of the cap closing time.
It is easy to understand that, in view of the present invention designed for an intelligent trash can without a position sensor and a current sampling circuit, the can lid motor 300 is controlled by time, i.e., when the can lid is opened, the can lid motor 300 is turned forward for a period of time and then is closed; when the cover is closed, the cover motor 300 is turned back for a while and then is closed. The cover opening time refers to the time required by the cover motor 300 to open the cover 200, and the cover closing time refers to the time required by the cover motor 300 to close the cover 200.
The end period of the cover opening time refers to a period of time at the tail section in the cover opening time process, and the length of the period of time can be determined according to the adsorption state of the permanent magnet electromagnet 400 and the first magnetic attraction piece 500, for example, the time when the first magnetic attraction piece 500 enters the attraction range of the permanent magnet electromagnet 400. In this embodiment, the permanent magnet electromagnet 400 can be kept in the power-off state all the time during the process of opening the cover.
The initial period of closing time refers to a period of time in the first period during the closing time, and the length of the period of time can be determined according to the adsorption state of the permanent magnet 400 with the magnetic attraction piece, and the period of time in this embodiment should at least ensure that the magnetic attraction piece is separated from the suction range of the permanent magnet 400, so as to avoid affecting the closing of the tub cover 200.
The intelligent garbage can cover 200 control circuit controls the permanent magnet electromagnet 400, the can cover motor 300 and other executive components to realize the functions as described above. Referring to fig. 5 to 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, referring to fig. 5, a power management circuit is constructed based on a linear voltage regulator U3 to reduce the voltage from 12V to 5V, so as 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 cover opening and closing commands according to cover opening and closing signals, so as to control the first driving circuit, the indicating circuit and the second driving circuit. Specifically, the main control chip U1 is provided with an IR-DAT pin to receive signals for opening or closing the cover; the motor driving chip U2 is provided with INC2 and INC1 pins for outputting level signals and controlling the motor driving chip U2; a PWMC2 pin is provided to control the indication circuit.
The first driving circuit is used for driving the tub cover motor 300, and comprises a motor driving chip U2, wherein the motor driving chip U2 is provided with a BI pin and a FI pin, and the tub cover 200 switches the level received by the pins and can control the tub cover motor 300. In one example, when the BI pin receives a low level and the FI pin receives a high level, the lid motor 300 is rotated 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 reversely rotates to execute the 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 R4 and the LED1 form an indicating circuit for indicating the current working state of the intelligent dustbin, and a light prompt is executed for a certain time before the instruction of opening or closing the cover is executed.
The trigger circuit is used for sensing a cover opening or closing signal and transmitting the cover opening or closing signal to the main control circuit. In this embodiment, an infrared trigger circuit is adopted, and specifically, as shown in fig. 7, the infrared trigger circuit is composed of an infrared receiving sensor U4, a capacitor C4 and an infrared tube emitting tube IR 1. When corresponding gestures or operations stop the infrared receiving sensor U4 from receiving infrared light of the infrared transmitting tube IR1, a trigger signal for opening the cover is obtained, and otherwise, a trigger signal for closing the cover is obtained.
The second driving circuit is configured to drive the permanent magnet electromagnet 400, as shown in fig. 8, and includes a resistor R5, a resistor R6, a triode Q2, and a diode D1; one end of the resistor R5 is connected with the main control chip to acquire 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 triode Q2 is grounded, and the resistor R6 is connected with the base electrode and the emitter of the triode Q2 in parallel; the collector 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 anti-parallel with the permanent magnet electromagnet 400.
In one example:
the main control chip U1 transmits 38KHZ PWM signals through the IR_OUT, after the infrared receiving sensor U4 receives the 38KHZ signals, the received signals are returned to the main control chip U1 through the IR_DAT, and the LED1 lamp is fully lighted.
When the main control chip U1 receives the 38KHZ signal of the IR_DAT, it outputs INC2 (low level) and INC1 (high level) signals to the motor driving chip U2 to perform forward rotation, the barrel cover 200 is opened at the moment, and after 2 seconds, it outputs INC2 (low level) and INC1 (low level) signals to the motor driving chip U2 to perform motor closing.
The main control chip U1 outputs a low-level signal through the B_MOTOR, and the triode Q2 is not opened, so that the permanent magnet electromagnet 400 is powered off to keep magnetism, and because the garbage can is close to the permanent magnet electromagnet 400 and is provided with the first magnetic attraction piece 500, the garbage can cover 200 is kept in an open state at the moment, and the garbage can cover 200 is attracted by the magnetism of the permanent magnet electromagnet 400, so that the can cover 200 does not rebound or automatically fall back.
The LED1 is gradually darkened within 3 seconds after the tub cover 200 is opened for 3 seconds, and when the main control chip U1 receives the ir_dat signal, the LED1 lamp is fully lighted and the tub cover 200 is continuously automatically turned off for 3 seconds. After the LED1 is turned off after 3 seconds of delay, the main control chip U1 outputs a high-level signal through the B_MOTOR to turn on the triode Q2 so that the permanent magnet electromagnet 400 is electrified to lose magnetism, meanwhile, the main control chip U1 outputs INC2 (high level) and INC1 (low level) signals to the MOTOR driving chip U2 to perform inversion, the barrel cover 200 is turned off at the moment, the main control chip U1 outputs a low-level signal through the B_MOTOR so that the triode Q2 is not turned on, and then outputs INC2 (low level) and INC1 (low level) signals to the MOTOR driving chip U2 after 2 seconds of delay, and the barrel cover 200 is turned off at the moment.
Example 2
Referring to fig. 1-4, the present invention also provides another embodiment, which is different from embodiment 1 in that: in addition to embodiment 1, an electromagnet 600 is added to the magnetic attraction assembly, and a third driving circuit is added to the control circuit. In addition, a permanent magnet electromagnet 400 is provided in the tub cover 200.
Similarly, the electromagnet 600 is disposed on the tub 100 corresponding to the adsorption position of the tub cover 200 in the closed state, and the electromagnet 600 and the permanent magnet electromagnet 400 repel each other.
Thus, when the lid motor 300 executes the lid closing instruction, the permanent magnet electromagnet 400 is switched to the power-off state before the end time of the lid closing time, the electromagnet 600 is kept powered on during the end time of the lid closing time, when the lid 200 is completely closed, the electromagnet 600 is electrified to generate magnetism, the permanent magnet electromagnet 400 is powered off to generate magnetism, and the polarities of the permanent magnet electromagnet 400 are opposite, so that the magnetic repulsion is used for buffering the falling speed of the lid 200, thereby avoiding the phenomena of abnormal sound, wind blowing (possibly causing liquid and peculiar smell in the lid to float out of the body 100 under the action of wind pressure) and the like caused by the gravity influence of the lid 200.
When the lid motor 300 executes the lid opening command, the permanent magnet electromagnet 400 is kept powered off for an initial period of the lid opening time, and the electromagnet 600 is kept powered on for an initial period of the lid opening time, so that magnetic repulsion is utilized to reduce the moment requirement on the lid motor 300 at the starting moment and prevent the additional load caused by the adhesion (such as possibly caused by garbage mucus) between the lid 200 and the edge of the barrel body 100, so that the lid motor 300 can select smaller power, further reduce the volume and improve the service life of the lid motor.
As a more preferred embodiment, the magnetic assembly may further include a second magnetic member 700. Similarly, the second magnetic attraction member 700 is disposed on the tub body 100 corresponding to the attraction position of the tub cover 200 in the closed state, and in this embodiment, the contact area between the second magnetic attraction member 700 and the electromagnet 600 is smaller than that of the permanent magnet electromagnet 400, so that the second magnetic attraction member 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 caused by the magnetic force between the electromagnet 600 and the permanent magnet 400, the attractive force between the second magnetic attraction member 700 and the permanent magnet 400 should be smaller than the repulsive force between the electromagnet 600 and the permanent magnet 400.
Thus, when both the electromagnet 600 and the permanent magnet electromagnet 400 are powered off, the permanent magnet electromagnet 400 generates magnetism to attract the second magnetic attraction member 700, on one hand, if the barrel cover 200 is not covered in place, the attraction force can be used for attraction; on the other hand, the garbage can is in a non-power consumption suction state in a normal state, so that accidental opening of the garbage can (such as strong wind in an outdoor environment) can be prevented, or garbage throwing management of the outdoor garbage can (such as time-division throwing of the garbage can in a community) can be facilitated, and the non-throwing period can be prevented from being opened by closing the control circuit self-locking barrel cover 200.
The electromagnet 600 is driven by the third driving circuit, and outputs a high-level signal to turn on the triode through a pin of the main control chip U1, and the low-level signal turns off the triode, so that the circuit principle is consistent with that of the second driving circuit, and details are omitted here.
Example 3
The invention also discloses a cover opening and closing method for realizing the opening and closing cover of the intelligent dustbin,
specifically, as shown in embodiment 1, the intelligent garbage can is provided with a can body 100, a can cover 200, a can cover motor 300 and a magnetic attraction component, wherein the magnetic attraction component comprises a permanent magnet electromagnet 400 and a first magnetic attraction piece 500, one of the permanent magnet electromagnet 400 and the first magnetic attraction piece 500 is arranged in the can cover 200, and the other one is arranged on the can body 100 corresponding to an adsorption position of the can cover 200 in an opened state.
The following method for opening and closing the cover is adopted:
when the lid motor 300 executes the lid opening command, the permanent magnet electromagnet 400 is kept powered off at least for the last period of the lid opening time;
when the cap motor 300 executes a cap closing command, the permanent magnet electromagnet 400 remains energized for at least a portion of the initial time of the cap closing time.
The method effectively prevents the phenomena of abnormal falling back and the like of the barrel cover 200 in the process of uncovering by the adsorption action of the permanent magnet 400 and the first magnetic attraction piece 500. The control logic is simple, the permanent magnet electromagnet 400 can not act in the process of opening the cover, the cover closing action can be completed by triggering the cover motor 300, and in the process of closing the cover, the permanent magnet electromagnet 400 is started for a short time, so that the magnetic force between the permanent magnet electromagnet 400 and the first magnetic attraction piece 500 disappears, and the cover motor 300 can complete the cover closing action; more importantly, based on the characteristics of the permanent magnet electromagnet 400, the intelligent garbage can is only powered on briefly in the cover closing process, and the rest time is in a power-off state, so that the low power consumption of the intelligent garbage can is ensured, and the using time of a power supply of the intelligent garbage can is not influenced basically.
In addition, as a preferred embodiment, an electromagnet 600 is added to the magnet assembly, and a permanent magnet electromagnet 400 is provided in the tub cover 200. Similarly, the electromagnet 600 is disposed on the tub 100 corresponding to the adsorption position of the tub cover 200 in the closed state, and the electromagnet 600 and the permanent magnet electromagnet 400 repel each other.
The method further comprises:
when the lid motor 300 executes the lid closing instruction, the permanent magnet electromagnet 400 is switched to the power-off state before the end of the lid closing time, and the electromagnet 600 remains powered on for the end of the lid closing time.
Thus, when the barrel cover 200 is completely closed, the electromagnet 600 is electrified and magnetized, the permanent magnet electromagnet 400 is de-electrified and magnetized, and the polarities of the electromagnet and the permanent magnet electromagnet are opposite and the magnetism repel each other, so that the falling speed of the barrel cover 200 is buffered, the falling speed is prevented from being too high due to the influence of gravity of the barrel cover 200, abnormal sound, wind blowing (possibly causing liquid, peculiar smell and the like in the barrel to float out of the barrel body 100 under the action of wind pressure) and the like are caused.
