The provision of the feeding hopper (4) facilitates dumping and entering of garbage and waste; moreover, by means of the provision of the inclined baffle (7) at the lower end of the feeding hopper (4), and the coordination between a reset spring (9) and rotatable connection of the inclined baffle (7) and the mounting block (8), it is convenient to seal and open the lower end of the feeding hopper (4). When opened, the lower end allows for entering of garbage, and when sealed, the lower end functions to achieve coordination with sealing and covering matching between the lid bin body (3) and the primary bin body (1), so as to prevent emission of unpleasant odor in the bin from making persons uncomfortable.
A: An efficient crushing feed hopper comprising a feed hopper (1), wherein a cover plate (2) is arranged at an upper end of the feed hopper (1); a longitudinal stirring electric motor (3) is arranged at an upper end of the cover plate (2); a stirring shaft (4) is arranged at a lower end of the longitudinal stirring electric motor (3) and located in the feed hopper (1); an auger delivery piece (5) is mounted on the stirring shaft (4); the feed hopper (1) has an upper portion in the shape of a cylinder and a lower portion in the shape of an inverted cone; a rotating shaft (6) is arranged below the stirring shaft (4) and located in the feed hopper (1); stirring blades (7) are mounted on the rotating shaft (6); the rotating shaft (6) is movably connected to a side wall of the feed hopper (1) via a bearing seat; a transverse stirring electric motor (8) is connected to an outer end of the rotating shaft (6); the transverse stirring electric motor (8) is fixedly mounted on the side wall of the feed hopper (1); a discharge tube (9) is arranged at a lower end of the feed hopper (1); and a feed port (13) is provided on the cover plate (2). By adding a longitudinally arranged stirring shaft and a transversely arranged rotating shaft in a feed hopper, agglomerate materials in the feed hopper can be double stirred, thereby ensuring sufficient crushing of the agglomerate materials, effectively preventing the materials from blocking the feed hopper and lengthening the usage life of the feed hopper.
B: A balance ring mounting structure, an inner tub having same and a washing machine. The balance ring mounting structure comprises a balance ring (1) and a tub body (2). The balance ring (1) is mounted on an upper opening of the tub body (2). An inward convex support portion (3) is provided at the periphery of the upper end of the tub body (2). An overlap portion (4) overlapped on the support portion (3) is provided at the outer periphery of the balance ring (1). A sealing element (5) is sandwiched between the support portion (3) and the overlap portion (4). The tub body (2) is rotatably riveted to the balance ring (1). A groove structure (6) stamped from outside to inside is provided at the periphery of the upper end of the tub body (2), an opening faces towards the outside of the periphery of the tub body (2), and the groove bottom is protruded inward the tub body (2). The support portion (3) is located above the groove structure (6). A water outlet (7) is formed below the support portion (3) of the inner tub of the washing machine. During dewatering, water in the tub climbs upwards under the centrifugal force and is guided to the outside of the tub from the water outlet (7). The washing machine is sealedly connected between the inner tub and the balance ring (3) to prevent water splashing between the inner tub and the balance ring (3) to cause potential safety hazard. The structure is simple, the sealing effect of the inner tub is good, and the dewatering is rapid.
C: Disclosed is a sealing garbage can, comprising a can body (1) and a can cover (2); a garbage receiving apparatus (5) is disposed on the can cover (2), the garbage receiving apparatus (5) comprises a cover body (501) and a rotation body disposed on the cover body (501), the cover body (501) closes the space inside a garbage bag, and a temporary storage compartment (508) is disposed on the rotation body; the can cover (2) is also provided with a garbage bag storage apparatus (3) and a garbage bag sealing apparatus (4); the can body (1) or can cover (2) is provided with a garbage bag infeed apparatus; the garbage bag storage apparatus (3) is installed under the garbage receiving apparatus (5); a garbage bag sealing apparatus (4) is mounted under the garbage bag storage apparatus (3); a controllable channel used for communicating with the external environment when a bag is inserted is disposed between the garbage receiving apparatus (5) and the garbage bag storage apparatus (3), or on the garbage receiving apparatus (5). The sealing garbage can has good sealing and deodorization performance as well as the function of automatically packing and sealing filled garbage bags. Furthermore, after removing a packed garbage bag, a new garbage bag can be communicated with the external environment such that bag infeed of the new garbage bag can be successfully completed.
D: A feeding barrel for drinking and ingestion, a drinking and ingestion integrated device, and a feeding control method, the feeding barrel for drinking and ingestion comprising a barrel body (1), independent discharging ports are provided on a lower end of the barrel body (1), a rotating rod (12) is rotationally arranged between adjacent material separating plates on each discharging port, a rotating plate (15) is fixedly arranged on each rotating rod (12), and a water tank (2) is also disposed on the barrel body (1). The drinking and ingestion integrated device comprises the barrel body (1), an ingestion groove (7) is provided below the barrel body (1), a plurality of partition plates (72) are provided within the ingestion groove (7), and a plurality of ingestion areas are formed therein.
