Garbage bag detection device, intelligent garbage can and automatic bag replacing control method

Abstract

The invention relates to the technical field of intelligent garbage cans, in particular to a garbage bag detection device, an intelligent garbage can and an automatic bag replacing control method. Thedevice comprises an emitting end and a receiving end; the emitting end is used for emitting signals; the signals are reflected by a garbage bag to form reflection signals; the receiving end is used for receiving the reflection signals; and the receiving end and the emitting end are arranged on the inner wall of the garbage can. Furthermore, the device comprises a fan and a control mechanism. In this way, when the garbage bag is automatically replaced, the position of the garbage bag in the garbage can can be detected, control is achieved according to the detected position information of the garbage bag, and after a new garbage bag is laid, laying is controlled to stop, and the problem that the garbage bag is sucked into the fan and damaged is also avoided. The garbage bag detection devicefacilitates protection of the garbage bag, saves resources, reduces potential safety hazards of the intelligent garbage can and improves the stability and reliability.

Description

technical field [0001] The present application relates to the technical field of intelligent garbage cans, and more specifically, to a garbage bag detection device, an intelligent garbage can and an automatic bag changing control method. Background technique [0002] With the advancement of science and technology and the improvement of people's living standards, smart homes have gradually become an indispensable part of daily life. Among them, smart trash cans have become the focus of people's attention because of their clean, hygienic and convenient use. [0003] Existing smart trash cans are generally equipped with an infrared sensing device at the position of the flip. When people pass by, the flip is opened, and when the person leaves, the flip is closed. Although the steps of opening and closing the flip can be saved, these simple functions are far from satisfying people's needs. need. Therefore, technicians in related fields have begun to study functions such as intel...

Problems solved by technology

[0003] Existing smart trash cans generally have an infrared sensing device installed at the position of the cover. When people pass by, the cover is opened, and when the person leaves, the cover is closed. Although the steps of opening and closing the cover can be omitted, these simple functions are far from satisfying people's needs. need

Therefore, technicians in related fields have begun to study functions such as intelligent sensing, automatic packaging, and automatic bag changing. Among them, automatic bag changing can solve the problem of time-consuming and laborious manual bag changing. The air inside is pumped out, so that the external atmospheric pressure is higher than the air pressure in the bucket. At this time, the garbage bag is pressed into the bucket due to the atmospheric pressure, thus completing the automatic bag change. However, due to the existing smart trash cans on the market, they are generally manual. Or semi-automatic bag replacement, without an effective detection device for detecting the position of the garbage bag in the bucket, it is impossible to judge whether the garbage bag has been laid. In the process of automatically replacing the garbage bag, it is easy to cause damage to the garbage bag, and even make There are potential safety hazards in smart trash cans, which limits the further intelligent development of smart trash cans

[0004] Therefore, how to solve the problem that the existing smart trash can cannot detect the position of the garbage bag in the trash can, which may easily cause the garbage bag part to be damaged during the automatic bag changing process, and how to meet the needs of the smart trash can in the process of further intelligence The problem of the position information of the garbage bag in the barrel is a key technical problem to be solved by those skilled in the art
