Problems solved by technology

[0003] Although the above-mentioned garbage can is simple in structure and easy to use, it does not take into account the setting of the normally open state of the lid of the garbage can
However, the existing inductive trash can is usually controlled by capacitive touch or physical buttons to realize the function of normally opening (maintaining the lid) of the trash can. This method has three major problems: 1. When there is a foreign object on the touch panel, In the case of dirt, false triggers are prone to occur; 2. In the process of user use, the panel is inevitably dirty, but to realize this function, it is necessary to touch the panel, which is easy to get dirty and inconvenient to use; 3. Through physical There is not only the second problem to realize the normal opening of the trash can by pressing the button, but also the troublesome operation, especially when both hands are holding the trash, it will be very troublesome to realize the function of keeping the lid open by pressing the button

Embodiment 1

[0031] One of the implementations of the method for controlling the opening of an inductive garbage can according to the present invention is as follows: figure 1 with Figure 3 to Figure 5 shown, including the following steps:

[0032] Step 1: The microcomputer program control unit controls the infrared emitter to emit infrared encrypted pulse signal light; the frequency of the infrared encrypted pulse signal light emitted by the infrared emitter is 38KHz. The infrared transmitter emits infrared encrypted pulse signal light at a frequency of 38KHz, which can improve the anti-interference ability of infrared rays and avoid infrared interference in the atmosphere.

[0033] Step 2: When a sensing object is placed in the sensing area above the sensing window, the infrared receiver receives the encrypted pulse signal light emitted by the infrared transmitter;

[0034] Step 3: The encrypted pulse signal light received by the infrared receiver is sequentially amplified by the ampl...

Embodiment 2

[0053] One of the implementations of the method for controlling the opening of an inductive garbage can according to the present invention is as follows: Figure 2 to Figure 5 As shown, the main technical solutions of this embodiment are basically the same as those of Embodiment 1, and the features not explained in this embodiment are explained in Embodiment 1, and will not be repeated here. The difference between this embodiment and Embodiment 1 is that the microcomputer control chip also includes a TEMP register, and the TEMP register is connected to the microcomputer program control unit. The TEMP register is used to temporarily save the current A / D conversion result for comparison with the value of the next A / D conversion register. Wherein, step 411 is also included between step 41 and step 5: the judging module judges whether the value stored in the A / D conversion register is continuously greater than the value of the TEMP register; if so, then enters step 5; if not, then...

Embodiment 3

[0061] One of the embodiments of an induction trash can of the present invention, such as Figure 3 to Figure 5 As shown, the main technical solution of this embodiment is basically the same as that of embodiment 1 or embodiment 2, and the features not explained in this embodiment adopt the explanation in embodiment 1 or embodiment 2, and are not repeated here . The difference between this embodiment and embodiment 1 or embodiment 2 is that step 3 and step 4 also include step 31: the sensor in front of the trash can detects whether there is an inductive object in front of the trash can, if yes, then enter step 4; if not , the microcomputer program control unit does not issue control instructions. The inductive trash can is also provided with a sensor for sensing objects in front of the trash can, and the sensor is connected with the microcomputer program control unit. When the user stands in front of the trash can, the sensor senses the user's use, and cooperates with the ex...

Abstract

A method for controlling the opening of an inductive trash can. A microcomputer program control unit controls an infrared emitter to emit infrared encrypted pulse signal light. When an inductive object is placed in the sensing area above the sensing window, the infrared receiver receives The encrypted pulse signal light received by the infrared receiver is sequentially amplified by the amplifier, converted by the A / D converter, and stored in the A / D conversion register; and then stored in the A / D conversion register by the judgment module The value of the sensing area 1 distance register and the sensing area 2 distance register are compared respectively. At the same time, the time the sensing object stays in the sensing area is compared with the value of the trigger time register for keeping the lid open to determine the normal opening triggered by the user. Cover mode or long-term open cover mode; users can trigger the sensor according to specific needs, with strong flexibility, effectively avoiding direct contact with the trash can with hands, and the design is more humanized.

Description

technical field [0001] The invention relates to the technical field of garbage cans, in particular to a method for controlling the opening of an inductive garbage can. Background technique [0002] Garbage cans are common garbage collection devices in daily life, and are generally divided into manually controlled opening and closing garbage cans and induction-type automatic control garbage cans. Existing induction trash cans, for example, the Chinese invention patent discloses "a kind of fully automatic infrared induction trash can" with the patent number ZL200920146228.6, the structure of which includes a bucket body and a bucket cover; , the edge of the bung is provided with an induction head, the induction head is provided with an induction window, and an infrared sensor is arranged in the induction window; the center of the bung is provided with a control panel that can be opened and closed, and the infrared sensor and the control panel connect. When objects or other o...
