Abstract

A blender includes abase and a container unit mounted rotatably and detachably on the base. The container unit includes a container, and a blade assembly disposed on a bottom portion of the container. The base includes a first push portion adjacent to the blade assembly which has a second push portion. When the container unit is rotated relative to the base until the second push portion contacts with the first push portion, the first push portion pushes upward the second push portion as the container unit is continuously rotated relative to the base so as to move the container unit upwardly and away from the base.

First claim

What is claimed is:

1. A blender comprising:
a base including a base surrounding wall defining a base space, and a first push portion protruding from an inner peripheral surface of said base surrounding wall and having a first push surface that is an oblique flat surface or a curved surface; and
a container unit mounted rotatably and detachably on said base, said container unit including a container, and a blade assembly disposed on a bottom portion of said container:
said first push portion being adjacent to said blade assembly;
said blade assembly including a blade holder having a blade holder surrounding wall, a plurality of blades disposed on said blade holder and surrounded by said blade holder surrounding wall, and a second push portion formed on a lower end of said blade holder surrounding wall and having a second push surface facing said first push surface, said second push surface having a lower end and an upper end, said second push surface extending from said lower end to said upper end thereof; and
when said container unit is rotated relative to said base until said second push portion contacts with said first push portion so as to detach from said base, said second push surface is moved into contact with said first push surface such that said first push surface moves along and pushes said second push surface from said upper end to said lower end thereof, and said first push portion pushes upward said second push portion as said container unit is continuously rotated relative to said base so as to move said container unit upwardly and away from said base;
wherein said container includes a container surrounding wall having a first threaded portion at a bottom portion thereof, and said blade assembly further includes a second threaded portion for connection with said first threaded portion.

2. The blender as claimed in claim 1 , wherein said container surrounding wall defines a receiving space having an upper opening, and said container unit further includes a cover for removably covering a top end of said container surrounding wall.

3. The blender as claimed in claim 1 , wherein said container further includes an end wall integrally connected to a top end of said container surrounding wall and cooperating with said container surrounding wall to define a receiving space.

4. The blender as claimed in claim 1 , wherein said blade assembly further includes an engaging slot spaced apart from and opposite to said second push surface of said second push portion for engagement with said first push portion.

5. The blender as claimed in claim 1 , wherein a tangent line (TL) passing through a contact point of said second push surface and said first push surface forms an acute angle (θ) with respect to a horizontal reference line (RL), and said acute angle (θ) is less than or equal to 45°.

6. The blender as claimed in claim 5 , wherein said acute angle (θ) is defined as 25°≤θ≤45°).

7. A pushing unit of a blender, the blender including a base and a container unit detachably mounted on the base, said pushing unit being configured to be disposed on at least one of the base and the container unit and being configured to push the container unit so as to move the container unit upward relative to the base when the container unit is rotated relative to the base;
wherein said pushing unit includes a first push portion formed on the base, and a second push portion formed on the container unit and pushed by said first push portion, said first push portion having a first push surface that is an oblique flat surface or a curved surface;
wherein said second push portion has a second push surface, said second push surface having a lower end and an upper end, said second push surface extending from said lower end to said upper end; and
wherein, when the container unit is rotated relative to the base to detach from the base, said second push surface is moved into contact with said first push surface such that said first push surface move along and push said second push surface from said upper end to said lower end.

8. The pushing unit as claimed in claim 7 , wherein a tangent line (TL) passing through a contact point of said second push surface and said first push surface forms an acute angle (θ) with respect to a horizontal reference line (RL), and said acute angle (θ) is less than or equal to 45°.

9. The pushing unit as claimed in claim 8 , wherein said acute angle (θ) is defined as 25°≤θ≤45°.
