Liquid stirring device

Abstract

A liquid stirring device comprises: a shell (1), a container (2), a container cover (3), a drive device (4), a suspending device (6), and a stirring head (5). The drive device (4) is arranged below the container (2); the suspending device (6) and the stirring head (5) are arranged in the container (2). The stirring head (5) is positioned in the container (2) through the suspending device (6); an upper part of the suspending device (6) is fixed on the container cover (3). A shaft of suspending device (6) includes an upper section (6.1) and a lower section (6.3); the upper section (6.1) and the lower section (6.3) are connected through an elastic connecting device (6.2). An upper part of the drive device (4) is provided with a magnet device (4.3), and a lower part of the stirring head (5) is provided with a magnet device (5.3); a lower part of the suspending device (6) is provided with a magnet device (6.4), and an upper part of the stirring head (5) is provided with a magnet device (5.4). The drive device (4) drives the stirring head (5) through the magnetic action of the magnet devices (4.3, 5.3), and together with the magnet device (6.4) at the lower part of the suspending device (6), positions the stirring head (5) through magnetic action. The liquid stirring device positions the stirring head (5) from the lower part through a magnetic force, and also positions the stirring head (5) from the upper part through a magnetic force, so that during rotation, the stirring head neither contacts the bottom of the container (2) nor contacts the suspending device (6), hence reducing the friction of the stirring head (5) during rotation, and improving the working efficiency.

Description

technical field [0001] The invention relates to a liquid stirring device, in particular to a liquid stirring device with a stirring head in a suspended state during operation. Background technique [0002] Some common liquid stirring devices on the market fix the stirring head on the container cover through a connecting rod or shaft; some fix the stirring head on the bottom of the container through a connecting rod or shaft. [0003] The stirrer involved in the patent application number 200810137652.4 and the title of the invention is an appliance and method for preparing foam from food liquid is positioned in the container by a positioning device, which is a protrusion or a recess, and the positioning device is compatible with the The bottoms of the containers together form an integral wall. [0004] The liquid stirring device that fixes the stirring head on the container cover through a connecting rod or shaft, its driving device is generally also on the container cover, ...

AI Technical Summary

Problems solved by technology

[0004] The liquid stirring device that fixes the stirring head on the container cover through a connecting rod or shaft, its driving device is generally also on the container cover, one of its disadvantages is that the container cover is relatively heavy, and it is inconvenient to open or close the container cover; its second disadvantage It is because the liquid in the container is boiled and expanded or the liquid in the container overflows to the container cover due to the high-speed rotation of the stirring head, which will cause the power supply in the drive device to communicate with the liquid on the container cover and cause electric shock to people who touch the container cover; The third disadvantage is that the stirring head is fixed on the connecting rod or shaft on the container cover, it is inconvenient to clean the stirring head, and the dirt in the gap between the stirring head and the connecting rod or shaft is difficult to clean

[0005] A liquid stirring device that fixes the stirring head on the bottom of the container through a connecting rod or a shaft. The connecting rod or shaft of the driving device extends through the bottom of the container to the interior of the container and is fixed with the stirring head. One of the disadvantages is the connecting rod or shaft of the driving device. Extending through the bottom of the container to the inside of the container, this production process is relatively cumbersome, especially the corresponding sealing process is cumbersome, especially when the liquid in the container may be heated to boiling, the requirements for sealing materials will be relatively high; The second disadvantage is that it is inconvenient to clean the part where the connecting rod or shaft of the driving device passes through the bottom of the container; the third disadvantage is that the stirring head is fixed on the connecting rod or shaft at the bottom, so it is not convenient to clean the stirring head. The dirt in the gap between the connecting rod or the shaft connection is difficult to clean

[0006] In the application number 200810137652.4, the title of the invention is the device and method for preparing foam from food liquid. The positioning device in the patent is a protrusion or a recess at the bottom of the container. Positioning the agitator, so there will be special requirements for the shape of the protrusion or recess, so it is not generally a simple groove and protrusion stamped on the container wall, and its production process is relatively troublesome; its disadvantages The second is that the protrusions or recesses are inconvenient to clean; the third disadvantage is that when rotating at high speed, the stirring head may break away from the protrusions or recesses where it is positioned.
