the upper space of the support is used for placing continuous point-broken garbage bags, and openings are formed in the connecting positions of the point-broken garbage bags and are used for triggering the hairpin bag opening device, so that length errors cannot be generated when the garbage bags are replaced each time.
When the sliding pull hook is used, the pedal is stepped on, the pedal drives the rotating rod to deflect, one end of the rotating rod pushes the uncovering push rod upwards, the uncovering push rod pushes the uncovering push rod to open, meanwhile, the protruding rod on the pedal drives the sliding pull hook to move downwards, the main tension spring on the sliding pull hook is lengthened, and meanwhile, the locking hook blocks the lower edge of the sliding pull hook under the tension of the resetting tension spring to prevent the sliding pull hook from returning upwards. At this time, the upper support rod and the lower support rod form a straight line to lean against one side of the sliding groove of the support, the stress rod is supported and cannot be pulled down by the main tension spring, and the elongated main tension spring is used for providing power when being used for clamping bags. The pedal is released, the protruding rod on the pedal is separated from the sliding hook, and the flip cover is slowly closed under the action of the damper.
The bag clamping and opening device has the following action process that when garbage is required to be taken away, the pedal is depressed, the flip is opened, and the garbage bag mouth stuck on the reusable adhesive tape on the U-shaped clamping rod is pulled upwards after being folded by the hand. The continuous garbage bag moves upwards along the arc-shaped opening at the lower part of the inner barrel, the garbage bag in the box slides downwards through the gap between the bracket and the wall of the inner barrel, and the upper part of the L-shaped trigger rod can be inserted into an opening beside a broken line of the downward sliding garbage bag. The garbage bag is pulled continuously, the L-shaped trigger rod is driven to move downwards for a certain distance and then stops moving, the garbage bag is clamped on the L-shaped trigger rod and cannot be pulled continuously, the L-shaped trigger rod simultaneously pushes the trigger connecting rod to move downwards, the trigger connecting rod pulls one end of the sliding rod, the other end of the sliding rod pulls the upper supporting rod and the lower supporting rod to deflect and release a supporting state, at the moment, the locking hook leaves the sliding drag hook under the pulling of the reset tension spring, meanwhile, the stress rod is pulled downwards by the main tension spring, the stress rod drives the U-shaped rotating rod to deflect, the two ends of the U-shaped rotating rod move downwards and drive the long pull rod to move downwards, the long pull rod pulls the guide rod to deflect, the deflected guide rod drives the two U-shaped clamping rods to fold and clamp the garbage bag, the upper supporting rod drives the sliding rod to deflect downwards under the pushing of the stress rod, one end of the sliding rod, the triggering connecting rod pulls the L-shaped trigger rod to slide out of a hole of the garbage bag to drop to the lowest point of the support, and then the garbage bag point breaking line is torn off and the garbage bag is removed;
when the garbage bag is taken away, the pedal is loosened, the sliding draw hook and the stressed rod move upwards under the acting force of the main tension spring, the stressed rod pulls the upper support rod and the lower support rod to move to form a straight line and form a support dead point, the lower support rod enables the locking hook to deflect below the sliding draw hook through the reset tension spring, meanwhile, the trigger connecting rod deflects upwards under the action of the trigger connecting rod torsion spring, one end of the trigger connecting rod drives the L-shaped trigger rod to reset upwards, meanwhile, the guide rod deflects backwards under the acting force of the guide rod tension spring, the guide rod drives the small pull rod and the long pull rod to move upwards, the long pull rod drives the U-shaped rotating rod to deflect, meanwhile, the guide rod drives the two U-shaped clamping rods to open a garbage bag mouth through the reusable adhesive tape, and the bag mouth is not completely opened at the moment. Then the bag pressing cover is pressed down or the bag pressing cover is pressed down together with the flip cover, the outer edges of the flip pages arranged on the two sides of the bag pressing cover are contacted with the inner barrel opening to enable the bag pressing cover to deflect 90 degrees, the inner edges of the flip pages drive the garbage bag opening to press the inner barrel wall of the garbage can, the bag opening is completely opened, and the lock catch on the bag pressing cover enables the bag pressing cover to be clamped on the inner side of the upper shell.
The cover opening and locking process is as follows, the turning cover is opened after the pedal is stepped on, one end of the knob is pressed down, the knob is clamped in a crack between the turning cover and the upper shell, the turning cover cannot return, and the other end of the knob is pressed down during unlocking. When the cover is locked, the bag pressing cover is opened at the moment, and the boss of the bag pressing cover contacts one end of the knob to enable the knob to deflect to release the cover locking, so that the cover opening locking device can be prevented from being damaged when the cover is pressed down together with the bag pressing cover after bag replacement.
In the process of changing the garbage bag box or the coiled garbage bag, the pedal flip cover is stepped on to open, then the bag pressing cover is opened, the inner barrel is lifted, a new garbage bag is pulled out from the box for a certain distance, the garbage bag box is inserted into the upper end of the support from the side face and is put back into the inner barrel, the garbage bag is pulled out from the arc-shaped opening at the lower part of the inner barrel by hands until the U-shaped clamping rod clamps the garbage bag opening, the bag opening is automatically opened after the pedal is released, and the bag pressing cover is closed to finish the garbage bag changing step.
Further, the opening is in a shape of a W and an M opposite to each other when the garbage bag is closed.
According to the garbage can, after garbage is taken out, a new garbage bag does not need to be sleeved manually, the bag does not need to be opened by hands or in a blowing mode, the steps of changing the garbage bag and the garbage bag box are simple, and a large number of pre-installed garbage bags can be stored on the side face of the garbage can for use.
