Description

Technical Field

[0001] The utility model belongs to the technical field of intelligent trash cans, and in particular relates to an intelligent trash can with energy-saving control. Background Art

[0002] Trash cans are mainly used to hold garbage and waste. Among them, trash cans with lids can isolate odors, are convenient and hygienic, and are widely used. With the advancement of technology, it has become a new trend to drive the opening of trash can lids by motors. However, at the moment when the motor drives the lid to open, the motor needs to provide a large torque, the motor load is large, and the energy consumption is high, so it is necessary to make improvements.

[0003] In the prior art, a Chinese patent with publication number CN207827099U provides a flap assembly and a smart trash can. The flap assembly includes a flap and a base. One side of the flap is pivotally connected to the base. A driving device is provided in the base. The driving device is connected to the flap in a transmission manner to control the flap to be flipped up or closed relative to the base. At the same time, a torsion spring is also provided between the reduction box and the rocker. The torsion compression of the torsion spring provides torque for the flap, making it easier to flip up. The trash can flap assembly is provided with a torsion spring for balancing the gravity of the lid at the motor shaft, which reduces the load of the motor to a certain extent. However, in actual applications of the trash can flap assembly, the selection of the torsion spring requires repeated testing, which is quite inconvenient. On the one hand, if the selected torsion spring torsional force is too large, the lid opens smoothly, but when the lid is closed, the motor output torque needs to overcome the additional torsion spring torsional force, and the battery energy consumption is large; on the other hand, if the selected torsion spring torsional force is too small, the lid closes smoothly, but when the lid is opened, the motor output torque needs to overcome the gravity of the lid, and the battery energy consumption is also large.

[0004] Therefore, in view of the problems existing in the prior art, it is urgently necessary to provide a trash can structure with a simple structure and convenient adjustment of the torsion spring torque. Summary of the invention

[0005] In view of the problems in the related technology, the utility model proposes an intelligent trash can with energy-saving control to overcome the technical problems in the prior art that the torsion spring torque on the driving motor of the flip-top trash can is difficult to adjust and the energy consumption is high.

[0006] The technical solution of the utility model is implemented as follows: an energy-saving controlled intelligent trash can, comprising a bucket head and a bucket body arranged from top to bottom; the bucket head comprises a bucket ring and a bucket cover hinged on the bucket ring; the bucket ring is also provided with a flip cover mechanism, and the bucket cover flips around its hinge point under the drive of the flip cover mechanism;

[0007] The flip cover mechanism comprises a driving unit, the output shaft of the driving unit is drivingly connected to a swing arm, a push rod is hinged on the swing arm, and the other end of the push rod is drivingly connected to the barrel cover; a plurality of limiting holes are arranged on the swing arm, and the plurality of limiting holes are spaced apart along the circumference of the output shaft of the driving unit; a torsion spring is also sleeved on the output shaft of the driving unit, one end of the torsion spring is in contact with the housing of the driving unit, and the other end is inserted into the limiting hole of the swing arm;

[0008] A sensing window is provided on the top of the barrel ring, and a sensing element is provided below the sensing window. The sensing element receives the sensing signal for triggering the opening and closing of the barrel cover through the sensing window. A controller is also provided on the barrel ring, and the controller is electrically connected to the sensing element and the driving unit respectively. The controller controls the output shaft of the driving unit to rotate forward / reverse according to the sensing signal received by the sensing element, thereby driving the barrel cover to open and close.

[0009] The utility model provides a plurality of limiting holes on the swing arm, and the plurality of limiting holes are spaced and distributed along the circumferential direction. The torsion force of the torsion spring is adjusted accordingly by inserting the torsion spring into the limiting hole at different positions, so that the torque output by the driving unit, the torsion force of the torsion spring and the gravity of the barrel cover interact to form a balance, which facilitates the opening and closing of the barrel cover and saves effort and energy.

[0010] As a further improvement of the above scheme, the swing arm includes a disk portion, a rotating shaft hole is provided in the middle of the disk portion, and the limiting holes are arranged in a ring shape on the disk portion around the axis of the rotating shaft hole, and the output shaft of the driving unit passes through the rotating shaft hole and is connected to the swing arm drive; one end of the disk portion protrudes and extends to form a rod portion, and the push rod is hinged on the rod portion; by arranging the rocker arm and the push rod, the rotational motion of the output shaft of the driving unit is converted into the up and down flipping motion of the barrel cover, and the structure is simple, stable and reliable.

[0011] As a further improvement of the above scheme, when the barrel cover is closed, the rod of the swing arm swings obliquely downward, and the hinge point between the top rod and the swing arm is lower than the axis of the shaft hole; when the barrel cover is fully opened, the rod of the swing arm swings obliquely upward, and the hinge point between the top rod and the swing arm is higher than the axis of the shaft hole;

[0012] It should be noted that when the lid is closed, the hinge point between the top rod and the swing arm is lower than the axis of the shaft hole, and the swing arm is in a relatively inclined state. This inclined state can reduce the thrust required to flip the lid, thereby saving effort; similarly, when the lid is fully opened, the swing arm is also in an inclined state, which is conducive to the closing of the lid.

[0013] As a further improvement of the above scheme, when the barrel cover is closed, the torsion spring is inserted into one end of the limiting hole and is subjected to force, and the torsion spring is twisted to store energy; when the barrel cover is just opened, the torsion spring restores its deformation and releases energy; the setting of the torsion spring can reduce the load of the drive unit, balance the gravity of the barrel cover, and make the opening of the barrel cover more labor-saving.

[0014] As a further improvement of the above scheme, the drive unit includes a motor and a gear box, wherein the gear box is provided with a plurality of gears meshing with each other, and the torque of the motor is transmitted to the output shaft through the gears. The torque generated by the motor is transmitted to the output shaft through the meshing of the gears in the gear box, and this transmission method can ensure higher efficiency and reduce energy loss; at the same time, the gears in the gear box are meshed with each other, and this design can withstand greater torque and pressure, and thus has a longer service life.

[0015] As a further improvement of the above scheme, the housing of the drive unit includes an end cover, which is arranged on the end face of one side of the output shaft of the drive unit; the end cover is provided with a guide sleeve extending along the circumference of the output shaft, and the output shaft is exposed after passing through the guide sleeve; the torsion spring is sleeved on the guide sleeve, and a stop block is provided at the lower part of the guide sleeve, and the torsion spring abuts against the stop block; the provision of the guide sleeve facilitates the installation and positioning of the torsion spring, and also reduces the friction resistance between the torsion spring and the output shaft during torsional deformation.

[0016] As a further improvement of the above solution, the limiting hole is a waist-shaped hole, a round hole or a rectangular hole.

[0017] As a further improvement of the above solution, a hinge seat is provided on the barrel cover, the barrel cover is hinged to the barrel ring through the hinge seat, and one end of the push rod away from the swing arm is hinged to the hinge seat.

[0018] As a further improvement of the above solution, there is an inwardly sunken groove between adjacent limiting holes, and the outer contour of the groove is adapted to the shape of the limiting holes on both sides; during the forming process of the swing arm, the forming material may deform due to the effect of internal stress. The existence of the groove can fix and limit the deformation of the product to a certain extent, and maintain the stability of its shape and size.

[0019] As a further improvement of the above solution, the number of the limiting holes ranges from 4 to 12.

[0020] Beneficial effects of the utility model:

[0021] The utility model provides a plurality of limiting holes on the swing arm, and the plurality of limiting holes are spaced and distributed along the circumferential direction.
