Abstract

The cutter stand of a mixer includes a set of blades and a blade holder installed at the bottom of the bowl of a mixer. The set of blades has a vertical shaft extending downward and the blade holder is fitted on the shaft, with a clutch installed under the blade base and threadably assembled with the shaft. The blade holder is composed of a bearing base, a copper alloy bush, a bearing sleeve, two heat-insulating and waterproof washers and a waterproof gasket. The shaft is inserted through the bearing sleeve, the copper alloy bush and the bearing base and then threadably assembled with the clutch connected with a motor which will drive the shaft to rotate and actuate the set of blades to rotate and beat fruit into juice. Thus the cutter stand of a mixer is assembled quickly, having effects of heat insulation, shock absorption and noise abatement.

Claims

1. The cutter stand of a mixer comprising:

a bowl formed with a support base at the bottom, said support base bored with plural threaded holes at the lower side, said bowl having its lower side bored with an insert hole in the center at the bottom, said insert hole provided under with an annular stop edge;

a set of blades installed at the lower portion of said bowl, said set of blades secured on a vertical shaft extending downward, said shaft inserted through said insert hole of said bowl, said shaft having its lower end formed with a threaded portion;

a blade holder assembled under said set of blades;

a clutch assembled under said blade holder, said clutch threadably assembled with said set of blades; and

,

characterized by said blade holder composed of a bearing base, a copper alloy bush, two waterproof washers, a bearing sleeve and a waterproof gasket, said bearing base threadably assembled with said support base of said bowl, said bearing base formed with a chamber inside, said chamber bored with a through hole at the bottom, said copper alloy bush received in said chamber of said bearing base, said copper alloy bush formed with an axial passageway in the interior, said two waterproof washers respectively assembled on the upper and the lower end of said copper alloy bush, said bearing sleeve assembled on said bearing base, said bearing sleeve having its upper end inserted upward through said insert hole of said bowl, said bearing sleeve bored in the center with an axial through hole aligned to both said passageway of said copper alloy bush and said through hole of said bearing base, said waterproof gasket fitted around said bearing sleeve;

said bearing base enabling the components of said blade holder to be positioned easily, said cutter stand able to be assembled quickly and having excellent effect of heat insulation, said waterproof gasket and said two waterproof washers also having effects of shock absorption and noise abatement and of preventing oil splashing.

2. The cutter stand of a mixer as claimed in claim 1, wherein said bearing base of said blade holder is provided with an extending-up neck on the central portion and bored with plural threaded holes to match with said threaded holes of said bowl, with bolts inserted upward in said threaded holes to fix said bearing base under said support base of said bowl, said bearing sleeve having its lower side formed with a flange for said waterproof gasket to rest thereon, said waterproof gasket provided with a flange around its lower outer side, said flange pushing against said stop edge of said support base of said bowl.

3. The cutter stand of a mixer as claimed in claim 1, wherein said waterproof gasket and said waterproof washers of said blade holder are made of a waterproof and heat-insulating material.
