Description
Technical field
The utility model relates to a kind of sewage disposer, particularly a kind of sewage disposer with atmospheric buffer device.
Background technology
Sewage disposer is requisite articles for use in people's daily life, sewage disposer commonly used all is to be provided with pedal in entire body, and pedal connects strut by stepping on arm, when needs are opened bung, push down on the pedal, the interaction by each parts can realize opening of bung.
At present, most foot-operated sewage disposer is not all installed shock absorber, causes in the bung closure, rigid collision occurs between bung and the staving, thereby can produce larger noise, and, because regular like this collision also can be easy to cause the damage of sewage disposer.For this situation, although now also have some sewage disposers to be provided with shock absorber, these often install complicated structure or result of use undesirable, can not satisfy user's demand.
The utility model content
For addressing the above problem, it is a kind of rational in infrastructure simple that the purpose of this utility model is to provide, a kind of sewage disposer with atmospheric buffer device of middle generation noise capable of reducing using.
The technical scheme that the invention for solving the technical problem adopts is:
A kind of sewage disposer with atmospheric buffer device, the open-and-close mechanism that comprises bung, exterior bowl, interior bucket and the folding of control bung, open-and-close mechanism is installed in the backboard top of exterior bowl, bung is connected with strut in the open-and-close mechanism, described open-and-close mechanism also comprises atmospheric buffer device, this atmospheric buffer device comprises bounce cylinder and piston, and piston places bounce cylinder inside and is connected with the piston handle bottom, and the piston handle top is connected with strut.When the needs bung is closed, decontrol pedal, bung is closed downwards under the effect of self gravitation, the drive strut moves downward, strut pulling piston moves downward, and the air in the bounce cylinder is pushed, but because the air in bounce cylinder can not quick drain, thereby the air resistance speed that piston moves downward that slowed down, so that bung can not send the noise of collision when closure.
Further, the circumference of described piston is provided with groove, and double-layer seal rings is housed in the groove.Double-layer seal rings is so that produce certain friction force during relative motion between piston and the bounce cylinder, thus the speed of the piston movement that slows down.
Further, be arranged with two pores on the chassis edge of described piston.When bung is closed, when piston moved downward, air can pass through pore, but the double-layer seal rings in this moment groove can because the relation of air pressure open, thereby the quick discharge of obstruction air is played and is slowed down the speed that piston moves downward.And open when bung, during the piston upward movement, then this situation can not appear.Therefore, in actual use, the speed that bung is opened can be greater than its closed speed.
Further, described exterior bowl front lower is equipped with pedal, and pedal connects steps on arm, steps on the strut that the terminal connection of arm can strut bung.
Further, interior bucket detachably is installed in the exterior bowl.When tipping rubbish, the user only need take out interior barrel of rubbish of toppling over the inside and get final product, and need not take together by whole sewage disposer, is user-friendly to.
The beneficial effects of the utility model are: a kind of sewage disposer with atmospheric buffer device that the utility model adopts, the open-and-close mechanism that comprises exterior bowl, interior bucket, bung and the folding of control bung, open-and-close mechanism is installed in the backboard top of exterior bowl, bung is connected with strut in the open-and-close mechanism, described open-and-close mechanism also comprises atmospheric buffer device, this atmospheric buffer device comprises bounce cylinder and piston, and the piston handle top is connected with strut, and piston places bounce cylinder inside and is connected with the piston handle bottom.Of the present utility model rational in infrastructure simple, when bung is opened, the speed of unlatching, and in closure, the bung closing speed is slower, thereby can not produce noise, and be conducive to protect sewage disposer, easy to use, satisfactory for result.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and example.
Fig. 1 is the overall schematic of a kind of sewage disposer with atmospheric buffer device of the utility model.
Fig. 2 is the side sectional view of a kind of sewage disposer with atmospheric buffer device of the utility model.
Fig. 3 is the structural representation of the utility model atmospheric buffer device.

The specific embodiment
With reference to Fig. 1 Fig. 4, a kind of sewage disposer with atmospheric buffer device of the present utility model, the open-and-close mechanism 4 that comprises bung 1, exterior bowl 2, interior bucket 3 and 1 folding of control bung, open-and-close mechanism 4 is installed in the backboard top of exterior bowl 2, bung 1 is connected with the strut 43 of 4 li of open-and-close mechanisms, described open-and-close mechanism 4 also comprises atmospheric buffer device 5, this atmospheric buffer device 5 comprises bounce cylinder 53 and piston 51, piston 51 places bounce cylinder 53 inside and is connected with piston handle 54 bottoms, and piston handle 54 tops are connected with strut 43.When needs bung 1 closure, decontrol pedal 41, bung 1 is closed downwards under the effect of self gravitation, driving strut 43 moves downward, strut 43 pulling pistons 51 move downward, and the air that bounce cylinder is 53 li is pushed, but because the air in bounce cylinder 53 can not quick drain, thereby the air resistance speed that piston 51 moves downward that slowed down, so that bung 1 can not send the noise of collision when closure.
Further, the circumference of described piston 51 is provided with groove 55, and double-layer seal rings 52 is housed in the groove 55.Double-layer seal rings 52 is so that produce certain friction force during relative motion between piston 51 and the bounce cylinder 53, thus the speed of piston 51 motions of slowing down.
Further, be arranged with two pores 56 on the chassis edge of described piston 51.When bung 1 closure, when piston 51 moved downward, air can pass through pore 56, but this moment the double-layer seal rings 52 in the groove 55 can because the relation of air pressure open, thereby hinder the quick discharge of air, play and slow down the speed that piston 51 moves downward.And open when bung 1, during piston 51 upward movement, then this situation can not appear.Therefore, in actual use, the speed that bung 1 is opened can be greater than its closed speed.
Further, described exterior bowl 2 front lower are equipped with pedal 41, and pedal 41 connects steps on arm 42, steps on the strut 43 that arm 42 terminal connections can strut bung 1.
Further, interior bucket 3 detachably is installed in the exterior bowl 2.When tipping rubbish, the user only need take out interior barrel 3 rubbish of toppling over the inside and get final product, and need not take together by whole sewage disposer, is user-friendly to.
