Title: Kitchen garbage can

Description:
TECHNICAL FIELD 
     The present invention relates to a garbage bin, more specifically to one kind of damping side sliding style garbage can. 
     BACKGROUND 
     Garbage cans are commonly used sanitary utensils in people&#39;s daily life. There are many types of garbage cans, and at the same time, the size and opening and closing methods are also different: currently some kitchen garbage cans are used to collect food waste and utilize a back-hanging structure, and the garbage can is directly hung on the door frame of the kitchen cabinet using a hook. The upper edge of the garbage can is close to the kitchen countertop, and it is inconvenient to configure the garbage can lid with the upper edge. Once the lid is set, when the lid is opened, the lid will rise a lot above the countertop, which will affect normal operation. Therefore, current kitchen hanging frame type garbage cans are generally not equipped with lids, and open garbage cans are not sanitary, easily spreading odors, which need to be dealt with in time.

     DETAILED DESCRIPTION 
     As shown in  FIGS. 1-10 , a kitchen garbage can including a garbage can body  1 , the garbage can body  1  including an outer casing, an inner casing  12  and an upper frame  13 , this inner casing  12  is accommodated in this outer casing, the outer casing including a base  10  and a cover  11 , the cover  11  is placed on this base  10 , and the upper frame  13  is set on the top opening of the cover  11 , a lid  2  arranged on the top end of the garbage can body  1 , the garbage can lid  2  connecting to the upper frame through a side sliding mechanism, a side sliding operating part  22  is arranged on the top of the lid  2 , a hanging board  5  is arranged on the outer side of the garbage can body  1 . 
     This top opening is square shaped, and the upper frame  13  is symmetrical with the top opening and also has a square shaped structure, the side sliding mechanism including a long rocker arm  31  and a short rocker arm  32 , one end of the short rocker arm  32  connectively hinged to an upper side wall on the front of the upper frame  13 , a groove  21  is arranged on the bottom of the lid  2 , the direction of allowable movement of the groove  21  is forwards and backwards, a slider is arranged on the other side of the short rocker arm  32 , the slider is accommodated inside groove  21 , the length of the short rocker arm  32  ensures that when lid  2  is opened or closed, as the slider slides in the groove  21 , the bottom of the moving lid  2  is always close to one side of the short rocker arm  32  arranged on the top opening of garbage can body  1 ; a connecting part  15  is arranged on the bottom left and right inner walls of the upper frame, the top of the connecting part  15  forming a step portion between the left and right inner walls of the upper frame, and the step portion is provided with a guiding groove  14  that penetrates the top surface of the connecting part, the bottom end of the long rocker arm  31  penetrates the guiding groove  14  and pivots on connecting part  15 ; a gear wheel  33  is arranged on the bottom end of long rocker arm  31 , and long rocker arm  31  is pivotally connected to the connecting part  15  through the gear shaft of the gear wheel  33 , the connecting part  15  is pivotally connected to a damping gear  16  meshed with gear wheel  33 , a reset connection part  35  is arranged on the lower end of this long rocker arm  31 , this reset connection part  35  is arranged on the left side or right side of gear wheel  33 , and a tension spring  17  is arranged between reset connection part  35  and upper frame  13 , the tension spring  17  providing the moving force when the lid  2  is closed, the top end of this long rocker arm  31  is connectively hinged near the back of lid  2 ; the rotation plane of long rocker arm  31  and this short rocker arm  32  is parallel with this groove  21 . 
     The present invention has a side sliding structure lid arranged on the top opening of the back-hung kitchen garbage can, when the lid is opened, a force exerted manually by hand on the slide sliding control part  22 , will move the lid  2  forward and out, and long rocker arm  31 , having gear wheel  33  centered on the gear shaft, rotates lid  2  forward, the short rocker arm  32  slides along groove  21  at the bottom of lid  2 , so that lid  2  rotates forward and at the same time the front end of lid  2  always slides close to the front side of the upper frame, and when the lid is opened and in place, lid  2  is suspended at the top opening by the long rocker arm and the short rocker arm, and the bottom surface of the lid will be close to the outer wall of the front side of the garbage can body, and will not affect normal operation of the kitchen countertop; when closing the lid  2 , it&#39;s only possible to push lid  2  upwards, and one side of the lid  2  is close to the front edge of the top opening and slides upwards while rotating with the gear shaft as the center, and as the gear wheel meshes with the damping gear, after the lid is pushed up a distance, the force exerted on the tension spring  17  arranged between the reset connection part  35  and the upper frame  13 , can be slowly eased and reset. 
     The lid of this present invention has a side sliding opening structure, the lid is pulled in an outward direction when opening, the lid will stay close to the front of the top opening and will rotate and slide to open, and during the opening process the lid will not protrude above the kitchen countertop, and in the final state the lid will be suspended vertically at the front wall of the garbage can body, so as not to affect the normal disposal of kitchen waste, and when pushing up the lid when closing, after pushing up a distance, the lid is automatically reset under the action of the tension spring, and the damping gear is activated, when opening and closing, the speed of the lid can be slowed down, so that it can be opened or closed slowly and at a uniform speed, and this structure is a reliable structure, convenient and hygienic.
