Abstract
Description
Technical Field
[0001] This utility model relates to the field of trash can technology, and in particular to a sensor-type trash can that adaptively adjusts the sensing distance. Background Technology
[0002] As a common waste collection device in daily life, some existing trash cans are designed with the function of automatically opening the lid when a person approaches in order to improve the user experience. The user experience of this function depends on whether the trash can can accurately detect the approaching person. In actual application scenarios, environmental factors will affect the use of this function. For example, if the trash can is placed under a narrow table, the sensing distance should not be set too high to avoid accidental triggering by detecting the table. However, if the trash can is placed in a more open location, a larger sensing distance is more conducive to detecting the user throwing away trash. This means that users need to adjust the sensing distance themselves, which is inconvenient. Utility Model Content

[0026] Figure 3 This is a schematic diagram of the module structure of the microprocessor-related control circuit in an embodiment of this utility model. Detailed Implementation
[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0028] As a common waste collection device in daily life, some existing trash cans are designed with the function of automatically opening the lid when a person approaches in order to improve the user experience. The user experience of this function depends on whether the trash can can accurately detect the approaching person. In actual application scenarios, environmental factors will affect the use of this function. For example, if the trash can is placed under a narrow table, the sensing distance should not be set too high to avoid accidental triggering by detecting the table. However, if the trash can is placed in a more open location, a larger sensing distance is more conducive to detecting the user throwing away trash. This means that users need to adjust the sensing distance themselves, which is inconvenient.
[0029] In view of this, this application provides a sensor-operated trash can with adaptively adjustable sensing distance. Figure 1 , 2 This is a schematic diagram of the structure of a sensor-operated trash can with adaptively adjustable sensing distance, provided in an embodiment of this application. Figure 1 , 2 The sensor-operated trash can may include, but is not limited to: a body 100, a head 200, and a double-door lid 300;
[0030] The bucket head 200 covers the upper end of the bucket body 100 and is detachably connected to the bucket body 100;
[0031] The double-door bucket lid 300 includes at least two door units that can be opened relative to each other, and the door units are hinged to the side edges of the bucket head 200.
[0032] A sensor window 210 is provided on the front side of the barrel head 200. An infrared transmitting and receiving module is provided inside the sensor window 210. The infrared transmitting and receiving module emits infrared light signals to the outside through the sensor window 210.
[0033] The bucket head 200 is also equipped with a microprocessor, which is connected to the infrared transmitting and receiving module and the double-door bucket lid 300 respectively. The microprocessor is configured to control the infrared transmitting and receiving module to emit infrared light signals and adjust the emission power of the infrared light signals according to the corresponding feedback signals, so as to adjust the corresponding sensing distance.
[0034] Specifically, the bin body 100 has a cavity, which serves as a space to hold waste. The structure of the bin body 100 can be designed as cylindrical or prismatic, etc., and is not limited in this embodiment. The bin head 200 covers the upper end of the bin body 100 via a detachable connection method such as a snap or latch. Meanwhile, a cavity is left in the middle of the bin head 200 for mounting a double-door bin lid 300. The double-door bin lid 300 includes at least two door units that can be opened relative to each other. The relative opening direction can be set to left-right or up-down; this embodiment uses the left-right direction as an example. Figure 2 The two door units are defined as the first door unit 310 and the second door unit 320, respectively. Each door unit is hinged to one of the edges on both sides of the bin head 200, so that the two door units can open and close normally. The space above the bin body 100 is covered by the bin head 200 and the bin lid 300, thus preventing garbage from overflowing.
[0035] Figure 1 , 2 The diagram shows the two states of the sensor-operated trash can lid 300 when it is open and closed. The lid 300 in the diagram is designed to open in the left and right directions.
[0036] On the other hand, in order to facilitate user control, a control panel is also provided on the bucket head 200. Taking the double-door bucket lid 300 which opens in the left and right directions as an example, the control panel can be set on the front side of the bucket head 200. On the control panel, a sensor window 210 is provided. The sensor window 210 is made of infrared-transparent glass or plastic and other materials. A space is provided in the sensor window 210, and an infrared transmitting and receiving module is set in the space. Thus, through the infrared light-transmitting sensor window 210, infrared light signals that detect the approach of objects are emitted outward, and feedback signals of detection feedback are received.
[0037] Furthermore, to achieve intelligent control of the trash can, the bin head 200 is equipped with a microprocessor. This microprocessor is connected to both the infrared transmitting and receiving module and the double-door bin lid 300, thereby controlling both. In other embodiments, the microprocessor can also be housed within the bin body 100. Through the arrangement of internal and external circuits, the microprocessor can control the infrared transmitting and receiving module to emit infrared light signals. Upon receiving a feedback signal, it can analyze and judge the signal, adjusting the transmission power of the infrared light signal accordingly. By changing the transmission power, the detectable distance of the infrared light is adjusted, thus achieving the effect of adjusting the sensing distance. It should be noted that this does not involve improvements to the program algorithm; the relevant functions are implemented through corresponding circuit design, and the program algorithm involved is existing technology.
[0038] This embodiment designs a sensor-operated trash can including a bin body 100, a bin head 200, and a double-door bin lid 300. The bin head 200 covers the upper part of the bin body 100 and is detachably connected to the bin body 100. The double-door bin lid 300 includes at least two door units that can be opened relative to each other. The door units are hinged to the two side edges of the bin head 200. A sensor window 210 is provided on the front side of the bin head 200. An infrared transmitting and receiving module is provided inside the sensor window 210. The infrared transmitting and receiving module can emit infrared light signals that detect the approach of objects through the sensor window 210. In addition, the bin head 200 is also provided with a microprocessor. The microprocessor is connected to the infrared transmitting and receiving module and the double-door bin lid 300 respectively. The microprocessor is configured to control the infrared transmitting and receiving module to emit infrared light signals and adjust the emission power of the infrared light signals according to the corresponding feedback signals to adjust the corresponding sensing distance. Compared to manually adjusting the appropriate sensing distance, this application can adaptively adjust the transmission power based on feedback signals through a microprocessor, thereby adjusting to a suitable sensing distance and improving the user experience of the trash can.
[0039] In some embodiments, the microprocessor further includes a maximum power register, a minimum power register, and a transmit power register. The maximum power register stores the maximum transmit power of the infrared light signal, the minimum power register stores the minimum transmit power of the infrared light signal, and the transmit power register stores the currently set transmit power of the infrared light signal.
[0040] The microprocessor is also configured to determine the transmit power range based on the feedback signal, the maximum transmit power, the minimum transmit power, and the transmit power, and to update the transmit power based on the median value of the transmit power range.
[0041] Optionally, to serve as a reference for determining the transmission power, this embodiment also utilizes registers within the microprocessor. Registers are high-speed storage components that support rapid data access. These registers store the maximum transmission power, minimum transmission power, and currently set transmission power of the infrared light signal, respectively, and are defined as the maximum power register, minimum power register, and transmission power register. The transmission power must fall within the range formed by the minimum and maximum transmission powers.
[0042] On the other hand, the microprocessor, through the design of related circuits, can also determine a suitable transmission power within the range of maximum and minimum transmission power based on the feedback signal. For example, taking the initial state as an example, the transmission power range is from the minimum to the maximum transmission power. The midpoint of this range is the average of the maximum and minimum transmission power, and an infrared light signal is emitted at the transmission power corresponding to this average value. Then, upon receiving the feedback signal, if the feedback signal indicates that an object has been detected, it means that the current transmission power may be redundant. The upper limit of the transmission power range is modified to the current transmission power, and the transmission power is re-determined based on the midpoint of the newly determined transmission power range. This new transmission power corresponds to one-quarter of the range formed by the minimum and maximum transmission power, and an infrared light signal is emitted again based on this new transmission power. Conversely, if the feedback signal does not indicate that an object has been detected, it means that the current transmission power may still be insufficient. The lower limit of the transmission power range is modified to the current transmission power, and the transmission power is re-determined based on the midpoint of the newly determined transmission power range. This new transmission power corresponds to three-quarters of the range formed by the minimum and maximum transmission power, and an infrared light signal is emitted again based on this new transmission power. The steps described above for re-determining the transmission power range and transmission power can be repeated. The appropriate transmission power is quickly determined by the binary search method. The process of determining the appropriate transmission power is the transmission power adjustment process defined in this embodiment.
[0043] By setting up multiple registers related to transmission power, the microprocessor can flexibly select the method for determining the transmission power based on the maximum and minimum transmission power, thereby improving the efficiency of the trash can in continuously filtering for suitable transmission power.
[0044] In some embodiments, the microprocessor further includes a comparison unit, which is used to compare whether the transmit power range is less than a preset accuracy range;
[0045] If the transmit power range is less than the preset accuracy range, after updating the transmit power based on the intermediate value, the transmit power adjustment process is determined to be over, and the sensing distance is determined based on the updated transmit power.
[0046] In response to the transmission power range being greater than or equal to the preset accuracy range, after updating the transmission power based on the intermediate value, the microprocessor re-controls the transmission of infrared light signals based on the updated transmission power and adjusts the transmission power based on the feedback signal.
[0047] In conjunction with the above embodiments, this embodiment sets a preset accuracy range to evaluate whether the repeatedly updated transmission power is appropriate. Specifically, the microprocessor also includes a comparison unit, which uses comparison logic circuitry to compare the transmission power range with the preset accuracy range. During the repeated updates of the transmission power range and transmission power, after each update, the transmission power range is compared with the preset accuracy range. When the transmission power range is less than the preset accuracy range, the accuracy requirements for infrared light detection are met, and the transmission power adjustment process can be stopped. The updated transmission power is the target transmission power. When the transmission power range is still greater than or equal to the preset accuracy range, it means that the accuracy requirements for infrared light detection are still not met. The transmission power range and transmission power are repeatedly updated to narrow the transmission power range until it is less than the preset accuracy range.
[0048] By setting up a comparison unit to compare the preset accuracy range and the transmission power range, a suitable cutoff point is provided for the process of repeatedly optimizing the transmission power accuracy, thereby improving the intelligence of the trash can in adaptively adjusting the transmission power.
[0049] In some embodiments, the microprocessor is configured to control the infrared transmitting and receiving module to emit infrared light signals in response to the trigger sensing opening of the double-door bucket lid 300, and to adjust the emission power according to the feedback signal to adjust the sensing distance.
[0050] In this embodiment, the transmission power adjustment process is set to be triggered once whenever the trash can senses an approaching object and the hinged lid 300 is opened. This process adjusts the transmission power to a suitable level and determines the corresponding sensing distance. By setting trigger conditions, the transmission power adjustment process can be initiated only when an object is detected, avoiding initiation in meaningless scenarios that could impact the trash can's energy consumption.
[0051] In some embodiments, the microprocessor further includes a sensing distance register and a counter, the sensing distance register being used to store the previous sensing distance corresponding to the previous transmit power adjustment, and the microprocessor being configured to compare whether the previous sensing distance and the current sensing distance are consistent.
[0052] In response to the previous sensing distance being the same as the current sensing distance, the counter increments by one. When the counter reaches the preset value, the transmission power adjustment process is stopped.
[0053] In response to the discrepancy between the previous sensing distance and the current sensing distance, the sensing distance is stored in the sensing distance register, and the counter is reset.
[0054] Furthermore, as usage time increases, after the trash can has repeatedly initiated the transmission power adjustment process described in the above embodiment, it may have already adjusted to a transmission power and sensing distance suitable for the current usage environment. Initiating the process again at this point would be wasteful of energy. Therefore, this embodiment sets up a sensing distance register and a counter within the microprocessor. The sensing distance register stores the sensing distance after the previous transmission power adjustment, defined as the previous sensing distance. After each process execution, the microprocessor compares the previous sensing distance with the currently adjusted sensing distance. If they are inconsistent, it indicates a change in the trash can's usage scenario, or that the previously determined sensing distance was still inaccurate, and the counter is reset. If they are consistent, the counter is incremented. When the counter reaches a preset value, such as 5 or 7 times, it means that the adjustment results of the transmission power and sensing distance have been the same multiple times without change, and the transmission power adjustment process can be stopped. For example, the activation condition described in the above embodiment, where the process is triggered whenever the double-door lid 300 is sensed and opened, can be temporarily disabled.
[0055] In other embodiments, the sensing distance register can also be configured to store the transmission power after the previous transmission power adjustment, and determine whether to count by comparing whether the previous transmission power and the current adjusted transmission power are consistent.
[0056] By setting a sensing distance register and counter, the trash can can intelligently determine whether the usage environment has stabilized and whether the continuous optimization and adjustment of the sensing distance can be stopped, thereby stopping the triggering of the transmission power adjustment process and reducing the energy consumption of the trash can.
[0057] In some embodiments, reference Figure 3 The front of the bin head 200 is also equipped with a touch panel, which is connected to the microprocessor. The touch panel is used to receive external touch input operations. The microprocessor is also configured to control the opening or closing of the sensor-operated trash can or the opening or closing of the double-door bin lid 300 based on the touch input operation.
[0058] Optionally, to improve the user experience of the sensor-operated trash can, a touch panel is provided on the front side of the can head 200. This touch panel can receive the user's touch input operation through capacitive touch sensing technology, and transmit the corresponding touch sensing signal to the microprocessor to realize touch control.
[0059] On the other hand, the touch panel features control buttons for turning the sensor-activated trash can power on or off, manually turning the double-door trash can on or off, and manually initiating the transmission power adjustment process, providing versatile control options to enhance the user experience.
[0060] In other embodiments, the touch panel may also be located in other positions, such as the rear of the bucket head 200 or the bucket body 100, and may be adjusted according to the designer's needs.
[0061] In some embodiments, reference Figure 3 An LED display module is also installed on the front side of the bin head 200. The LED display module is connected to the microprocessor and is used to display the power information and / or lid opening / closing information of the sensor-operated trash can.
[0062] Optionally, a graduation LED display module is also provided on the front side of the bin head 200. This LED display module is connected to a microprocessor to obtain information related to the state of the trash can and displays the information through the LED units in the module. The displayed content includes, for example, the current power signal of the sensor trash can, the opening and closing information of the double-door bin lid 300 representing the current state, and / or the execution status information of the transmission power adjustment process.
[0063] The LED display module provides users with intuitive visual feedback on the various states of the trash can, helping them understand how to use the sensor-operated trash can and improving the user experience.
[0064] In some embodiments, reference Figure 3 The front of the bucket head 200 is also equipped with a motor drive module, which is connected to the microprocessor and the double-door bucket lid 300 respectively. The motor drive module is used to drive the double-door bucket lid 300 to open or close according to the instructions of the microprocessor.
[0065] Optionally, a motor drive module is also provided on the front side of the bin head 200. The microprocessor controls the motor drive module to drive the motor unit, so that each door unit of the double-door bin lid 300 is affected by the motor unit to move, thereby driving the door unit to rotate and realize the opening or closing of the double-door bin lid 300, improving the intelligence of the trash can.
[0066] In some embodiments, reference Figure 3 The sensor-operated trash can also includes a power module, which is connected to a microprocessor and is used to provide power to the microprocessor via an external power source.
[0067] The sensor-operated trash can also contains a power module, which connects to an external power source to obtain electrical energy. After processing within the module, such as rectification and voltage regulation, the energy is converted into power to drive the sensor-operated trash can. This power module also supplies power to the microprocessor via a connection to the microprocessor. Furthermore, for other energy-consuming components within the trash can, although... Figure 3 The connection relationships are not shown in the diagram, but the power module is also connected to it and provides it with power. They will not be listed and explained here.
[0068] In some embodiments, the infrared light signal is set to a 38kHz carrier signal.
[0069] Optionally, the infrared transmitting and receiving module also modulates the infrared light into a carrier signal before transmitting it at a selected frequency of 38kHz. In other embodiments, it can be set to other frequencies according to the needs of the staff. By using a carrier signal for sensing, interference from other factors in the environment can be effectively reduced, improving the sensing accuracy of the trash can.
