Description
Technical field
The present invention relates to a kind of sealing configuration of food waste disposer.
Background technique
Food waste disposer is mainly used in shredding garbage, then directly enters sewerage, reduces the resting period of food refuse, makes it not perishable and grow mosquito.In prior art, food waste disposer mainly comprises base, upper casing, motor and cutterhead, crushing chamber is formed between base and upper casing, cutterhead is placed in crushing chamber, the motor shaft of motor is fixedly linked with cutterhead through after base, and the joint of motor shaft and drain pan is provided with seal ring, and cutterhead can rotate thus pulverize the swill in crushing chamber under the drive of motor in crushing chamber, and seal ring prevents the water in crushing chamber from entering in motor, guarantee that motor normally uses.Because seal ring is that common rubber material is made, easily aging, distortion, working life is low, and wear-resisting property is poor, very easily be worn in the rotation process of motor shaft, sealing is lower, and cutterhead pulverize head and be comparatively large and the swill that material is harder time, easily rock, thus easily damage seal ring.
Summary of the invention
There is above-mentioned deficiency to overcome in prior art, the invention provides a kind of simple and compact for structure, easy to use, wear resistance is good, sealing effect is good and use the sealing configuration of stable food waste disposer.
The technological scheme that the present invention solves its technical problem is: a kind of sealing configuration of food waste disposer, comprise seal ring and lower seal, described upper seal ring internal fixtion has upper wear-resisting ring, and on this, lower end of wear-resisting ring is stretched out outside the lower end of described upper seal ring;
Described lower seal comprises Shang Quan, Xia Quan and is connected to the taper sheath between described Shang Quan and lower circle, and this taper sleeve is big top and small bottom, described upper circle internal fixtion has lower wear-resisting ring, the upper end of this lower wear-resisting ring is stretched out outside the upper end of described upper circle, and the upper surface of this lower wear-resisting ring contacts with the lower surface of described upper wear-resisting ring;
One elastic component is installed in described lower seal, this elastic component comprises support ring, lower support ring and multiple connecting sheet be evenly connected between described upper support ring and lower support ring, and multiple described connecting sheet is unanimously helically upwards arranged, described upper support ring is supported in described upper circle, and described lower support ring is supported in described lower circle.
Further, described Shang Quan, lower circle and taper sheath are injection molded into one by quality of rubber materials, and the upper end of described taper sleeve is injection-moulded on the outside of the lower end of described upper circle, the lower end of described taper sleeve is injection-moulded on the inner side of the upper end of described lower circle, and described upper circle is injection-moulded on the lower end of described lower wear-resisting ring;
Described upper support ring, lower support ring and connecting sheet strike out one by stainless steel, and the upper end of described connecting sheet is connected on the periphery of described upper support ring, and the lower end of described connecting sheet is connected on the inwall of described lower support ring;
The inner side of the lower end of described upper circle is extended with baffle ring downwards, forms support slot between this baffle ring and described taper sleeve, and described upper support ring is placed in described upper support slot, is arranged with lower support groove in described lower circle, and described lower support ring is placed in described lower support groove.
Because Shang Quan, lower circle and taper sheath are injection molded into one by quality of rubber materials, and lower wear-resisting ring and upper circle one-body molded, not only simple and compact for structure, and convenient formation, and on enclosed support slot, lower circle has lower support groove, thus be convenient to the installation of elastic component and fix, because upper support ring, lower support ring and connecting sheet strike out one by stainless steel, simple and compact for structure, convenient formation.
Further, described upper seal ring is made up of quality of rubber materials, positioning ring groove is arranged with in the lower end of described upper seal ring, it is convex that the upper end convex of described upper wear-resisting ring is provided with the positioning ring be placed in described positioning ring groove, positioning ring groove matches with positioning ring is convex thus upper wear-resisting ring and upper seal ring is fixed, simple and compact for structure.
Further, described upper wear-resisting ring and lower wear-resisting ring are made up of a kind of material among SIC, SI-SIC, C-SIC, and wear-resisting property is better, can ensure not wear and tear for more than 10 years, long service life.
The present invention in use, lower seal is close on the upper end of base, upper seal ring is inlaid on the lower end of cutterhead, motor shaft is successively through base, lower seal, elastic component, lower wear-resisting ring, fix with cutterhead after upper wear-resisting ring and upper seal ring, the lower end surface of upper wear-resisting ring contacts with the upper-end surface of lower wear-resisting ring, when motor is rotated by motor shaft band movable knife disc, upper wear-resisting ring and upper seal ring rotate with cutterhead, thus wear-resisting ring is rotated relative to lower wear-resisting ring, upper seal ring can effectively prevent the water in crushing chamber from the joint between upper seal ring and cutterhead, and the joint between upper seal ring and upper wear-resisting ring enters on motor shaft, lower seal can effectively prevent water in crushing chamber from the joint between lower seal and base, and the joint between lower seal and lower wear-resisting ring enters on motor shaft, upper wear-resisting ring and lower wear-resisting ring are close to mutually and can be effectively prevented the water in crushing chamber from entering on motor shaft from the contacting point between upper wear-resisting ring and lower wear-resisting ring, thus further anti-sealing enters in base along motor shaft, good seal performance, reach the effect of protection motor.Because upper wear-resisting ring and lower wear-resisting ring are that wear-resistant material is made, not easy to wear, and in lower seal, elastic component is installed, under the effect of this elastic component, lower seal is close to base all the time, and lower wear-resisting ring is close to wear-resisting ring all the time, upper seal ring is close to cutterhead all the time, good sealing effect.And when cutterhead pulverize head and be comparatively large and the swill that material is harder time, elastic component also plays and regulates and the effect of balance, rocks little, can not cause the damage of seal ring and lower seal.
Beneficial effect of the present invention is: adopt said structure, not only simple and compact for structure, easy to use, steady, and wear resistance is good, sealing effect is good.
