The present disclosure relates to a garbage can of a daily necessity, and more particularly, to a thermal sensing type garbage can cover and a garbage can.
A sensitive garbage can includes an opening and closing system of a cover controlled by a circuit chip, and the opening and closing system of the cover consists of a sensor and a driving system. When an object enters a range of a sensitive area, the sensor will detect the existence of an obstacle and feed back a signal to the opening and closing system of the cover, and the opening and closing system of the cover receiving an instruction may control automatic opening of the cover. When the object leaves the range of the sensitive area, the sensor which does not detect the obstacle will also feed back a signal to the opening and closing system of the cover, so that the opening and closing system of the cover receiving an instruction controls automatic closing of the cover. The sensitive garbage can is powered by an internal power supply such as a battery, with low power consumption, and the power supply or an external power supply does not need to be changed frequently. Therefore, a user does not need to control opening and closing of the cover by hand pressing or foot pressing, and is able to throw garbage more easily and conveniently.
On one hand, the sensor of the existing sensitive garbage can is usually an infrared detector, and the sensitive garbage can using this sensor is easy to judge an ordinary object with a lower temperature and a human body with a higher temperature as the obstacles. Therefore, when the ordinary object enters the sensitive area of this sensitive garbage can, the garbage can cover may still be opened and closed automatically, thus increasing power consumption of the internal power supply and reducing a whole service life of the garbage can cover and the garbage can. On the other hand, the existing sensitive garbage can is usually driven by a DC motor assisted by a spring at an output end. When a heavy cover is driven, an opening and closing process of the garbage can cover is poor in stability during a whole opening and closing movement due to an excessively heavy weight of the cover. Furthermore, unexpected situations such as tilting and overturning of the garbage can easily occur due to unbalanced stress of the garbage can as a whole.
At present, it is urgent to provide a sensitive garbage can and a cover thereof which are able to improve the stability of the opening and closing process of the cover and a judgment accuracy of the opening and closing system for controlling the opening and closing of the cover.
The present disclosure is intended to solve at least one of the technical problems in the prior art. Therefore, the present disclosure provides a garbage can cover, which is able to strengthen supporting to the cover, and improve a stability of the cover and a judgment accuracy of an opening and closing system for controlling opening and closing of the cover.

With reference to
The motor 210 drives the first connecting rod 400 to swing through the rotating shaft 220 during use, thus driving the second connecting rod 500 to support the cover 300, and the cover 300 rotates around the rotating rod 110. After the cover 300 is turned up, the first torsional spring 600 abuts against the cover 300 and the shell 100 respectively to support the cover 300. Meanwhile, a pressure loaded on the third torsional spring 800 is released when the rotating shaft 220 rotates, so that the third torsional spring 800 generates a torque opposite to a rotating direction to the rotating shaft 220, so as to support the rotating shaft 220. Pairs of the first torsional spring 600, the second torsional spring 700 and the third torsional spring 800 support the cover 300 and the rotating shaft 220 respectively, so as to reduce a load on the motor 210 and improve a stability of the cover 300.
In addition, since the first torsional spring 600 and the second torsional spring 700 are symmetrically arranged along the rotating rod 110, a torsional force generated on the rotating shaft 220 of the motor 210 may be evenly transferred and distributed to the first torsional spring 600 and the second torsional spring 700 located on both sides of the rotating rod 110 and then further transmitted to the cover 300 during rotation of the cover 300, thus avoiding an unbalanced stress situation, and further improving the stability of the cover 300 during rotation of the cover 300.
It should be mentioned that in order to improve an accuracy, a stepping motor 210 is selected as the motor 210.
According to some embodiments of the present disclosure, the motor base 200 is provided with a plurality of receiving holes 230, the plurality of receiving holes 230 are arranged around an axis of the rotating shaft 220, and the end portion of the third torsional spring 800 is inserted into the receiving hole 230 for fixing. A torsion degree of the third torsional spring 800 may be adjusted by changing the insertion hole 230 into which the end portion of the third torsional spring 800 is inserted, thus changing elastic potential energy accumulated on the third torsional spring 800, and then changing a tightness thereof to meet requirements of different situations.
According to some embodiments of the present disclosure, the first torsional spring 600 is sleeved on the rotating rod 110, and the first torsional spring 600 is provided with a first abutting end 602 and a second abutting end 604. A rib 120 is arranged in the shell 100, the first abutting end 602 passes through the rib 120, and the second abutting end 604 abuts against a lower portion of the cover 300.
According to some embodiments of the present disclosure, the second torsional spring 700 is sleeved on the rotating rod 110, and the second torsional spring 700 is provided with a third abutting end 702 and a fourth abutting end 704. A rib 120 is arranged in the shell 100, the third abutting end 702 passes through the rib 120, and the fourth abutting end 704 abuts against a lower portion of the cover 300.
With reference to
According to some embodiments of the present disclosure, the upper cover 302, the middle cover 304 and the lower cover 306 are connected and fixed by fastening connection or snap connection and combined into the cover 300 with a large mass.
The present disclosure further provides a garbage can with the above garbage can cover. The garbage can according to an embodiment of a second aspect of the present disclosure includes the garbage can cover according to any one of the above items, and the garbage can includes a can body 400 and the garbage can cover according to the first aspect of the present disclosure.
According to some embodiments of the present disclosure, the garbage can further includes the thermal sensing device arranged on a front surface of the can body 400 and electrically connected with the motor 210. The sensitive garbage can using this sensor is able to distinguish an ordinary object with a lower temperature from a human body with a higher temperature. Therefore, when the ordinary object with the lower temperature enters a sensitive area of the thermal sensing type garbage can, the garbage can cover will not be automatically opened and closed. Only when a part (a hand or a foot, etc.) of the human body with the higher temperature enters the sensitive area of the thermal sensing type garbage can, the garbage can cover may be automatically opened and closed, thus improving a judgment accuracy of an opening and closing system for controlling opening and closing of the cover, reducing electric energy consumption of an internal power supply, and prolonging an overall service life of the cover and the garbage can. Certainly, in order to meet requirements of different consumers and usage scenarios, the thermal sensing device used in the present disclosure may also be replaced by other infrared sensors.
According to some embodiments of the present disclosure, the garbage can further includes a Hall positioning device 500 arranged at a middle portion of a front end of the cover 300 and a corresponding position on the can body 400. The cover 300 is able to be accurately butted and pressed on the can body 400 by the Hall positioning device 500 during closing of the can cover 300, so as to prevent deviation during closing of the cover, thus affecting a sealing performance of the cover.
According to some embodiments of the present disclosure, the can body 400 further includes two handles 402 arranged at corresponding positions on two sides of the can body 400. The user is able to lift the whole garbage can through the handles 402, thus being convenient for carrying and other operations.
The embodiments of the present disclosure are described in detail with reference to the accompanying drawings above, but the present disclosure is not limited to the above embodiments, and various changes may also be made within the knowledge scope of those of ordinary skills in the art without departing from the purpose of the present disclosure.
