Description

Technical Field

[0001] The utility model belongs to the technical field of household appliances, and in particular relates to a button assembly for a garbage disposer. Background Art

[0002] In the field of food waste disposer air switches, the button used is a component that compresses the air bag below it by transmitting mechanical force to generate air pressure to achieve switch conduction and closure. In the traditional production process of this button assembly, in order to assemble the metal cover sleeve, metal button cover sleeve, plastic cover, and plastic button and ensure that they are fixed and will not loosen or fall off, the following two production processes are generally used. The first process: first manually apply glue evenly on the metal button cover sleeve and the inner surface of the metal cover sleeve, and then combine them with the plastic button and plastic cover respectively, and finally place them on the pneumatic tooling for compression operation. The second process: the metal button cover sleeve and the plastic cover, the metal cover sleeve and the plastic cover are assembled by clearance fit. First, they are assembled together by hand, and then placed on a special tooling to tighten the metal cover.

[0003] The shortcomings of the above two processes are: the first process requires additional production costs and the product will be affected by the external environment. Since glue is required, it is necessary to investigate whether the existing glue on the market can meet the product requirements. If not, it is necessary to develop a special glue. Whether buying existing glue or developing special glue, it requires additional costs; and glue is greatly affected by the environment. Too high or too low ambient temperature will reduce the adhesion of glue and even cause the metal cover to fall off. The shortcoming of the second process is that it will cause damage to the metal surface. Since this process requires the metal cover to be tightened, the special tooling needs to use a larger air pressure. If the workpiece is not placed correctly, it may cause irreversible indentations on the metal surface. If large particles of hard objects such as iron filings, sand, etc. are attached to the surface of the special tooling or the surface of the metal cover, it will also cause surface damage. The appearance requirements of this component are relatively high, so the defective rate of this process is also relatively high. Therefore, it is necessary for technical personnel in this field to make improvements to the existing deficiencies. Utility Model Content

[0004] In view of the above problems, the utility model discloses a button assembly for a garbage disposer, which solves the problems of high production cost, great environmental pollution, low production efficiency and high defective rate of the existing button assembly.
