Rotary blade type intelligent trash can and control circuit thereof

Abstract

The invention relates to a rotary blade type intelligent trash can and a control circuit thereof. The rotary blade type intelligent trash can comprises a can cover, a can body, a can bottom, an inner can and a handle, wherein the can cover is arranged over the can body; the can bottom is located under the can body; the inner can is located in the can body and installed on the upper end face of the can bottom; the handle is installed between two lifting lugs of the inner can; four annular hasps are symmetrically arranged on the upper side of the can bottom and are clamped to the lower end of the can body. The control circuit comprises a master control module, an H bridge motor drive module, an infrared detection module, a signal amplification module, an indication module and a phase reversal module, wherein the infrared detection module is used for forming an electric pulse signal, the signal amplification module is used for amplifying the electric pulse signal of the infrared detection module, and the phase reversal module is used for providing a switch signal to the master control module. The rotary blade type intelligent trash can and the control circuit thereof can achieve the rapid and intelligent opening and closing function, and have the advantages that the structure is simple, operation is simple and convenient, closing performance is good, blade response time is short, gear transmission noise is low, the size is small, cost is low and the appearance shape effect is good.

Description

technical field [0001] The invention relates to a garbage can, in particular to a rotary vane type intelligent garbage can and its control circuit. Background technique [0002] As an indispensable necessity in human life, "trash can" has accompanied human beings through every era. Especially in today's household goods and hotel supplies market, it is even more indispensable; with the general improvement of people's environmental awareness and aesthetic level, the types and quantities of trash cans are constantly being renovated and increased, and people pay more attention to its beauty and practicality. characteristics, and the products are also developing in the direction of "small" and "intelligent". Since the launch of the smart trash can, it has been welcomed by consumers. Because of the large market demand and small investment, it is also favored by small and medium investors. [0003] The existing smart trash cans are mainly clamshell-type, but the flip-top smart tra...

Problems solved by technology

[0003] The existing smart trash cans are mainly clamshell-type, but the flip-top smart trash cans have the following disadvantages: 1. Due to the short sensing time and fast flipping speed, people feel that their hands have not yet been retracted in time, which makes it easy to flap the trash can. There are potential safety hazards in the hands of personnel; 2. Its structural design is not suitable for pouring soup garbage, and it is very easy to splash on the flip cover

Although there are also some products on the market that overcome the shortcomings of the flip-type, such as the rotary intelligent microcomputer dustbin disclosed in Chinese Patent No. 201120147189.9, which adopts a rotary opening, effectively avoiding the defects of the flip-type opening, but It still has some defects: 1. Fifteen blades are used, and the thickness of the blades is too thick, resulting in a large opening in the center when the blades are closed at the same time, the sealing performance is poor, and the garbage and unpleasant gas overflow; The shape of the blades are all crescent-shaped with large volume, the waste of raw materials is serious, and the cost is expensive; 3. Due to the large transmission range of the designed gears, it takes a long time to realize the opening and closing process of the blades, and the opening speed of the blades is slow. People throw garbage and wait for a long time; 4. Due to its large gear transmission range, in order to speed up the opening speed of the blades, it is necessary to increase the working speed of the transmission motor gear and the influence of various friction forces, resulting in a louder sound during the transmission process of the motor , seriously affecting people's lives; 5. The structure is designed with an induction panel, the lower barrel is not cylindrical, the appearance and shape of the barrel are poor, the structure is complex, difficult to process, and the cost is expensive; 6. In the process of intelligent control , is always in a charged state, resulting in high energy consumption, which will increase the cost of use, and does not meet the theme of energy saving
