Description

The present invention relates to a stirrer and a cover for a stirrer for stirring fluids such as liquids and powders, and more particularly to a stirrer and a cover for a stirrer for stirring building materials such as wall materials. Conventionally, portable agitators, used by workers to stir fluids such as wall materials, which are mixtures of liquids, powders, or granules, have been known (see Patent Document 1). When stirring wall materials using the agitator described in Patent Document 1, the general procedure is as follows: First, the wall material to be stirred is placed in a container such as a can. Then, the worker holds the agitator and rotates it with the blades at the tip of the agitator immersed in the wall material, thereby stirring the material. Furthermore, the blades are attached to the tip of the rotating shaft, and when the blades are immersed in the wall material, the wall material also adheres to the rotating shaft. When the shaft is rotated with the wall material attached, centrifugal force causes the wall material to scatter. This necessitates cleaning and results in the loss of wall material. Therefore, there was a need for a stirrer that would prevent the fluid being agitated from scattering even when rotated. Japanese Patent Publication No. 2015-139713 This is a perspective view showing a stirrer according to an embodiment of the present invention.This figure shows a stirrer according to an embodiment of the present invention, where (a) is a partial front cross-sectional view showing a portion of the stirrer, and (b) is a right side view.This is an enlarged, disassembled section cross-sectional view showing the disassembled state in part A of Figure 2(a).This is an enlarged cross-sectional view showing a magnified view of part B in Figure 2(a).A perspective view showing a modified example of a stirrer according to an embodiment of the present invention. Next, embodiments of a stirrer to which the present invention is applied will be described with reference to the drawings. While the embodiments described below are preferred embodiments of the present invention and therefore have various technically preferable limitations, the scope of the present invention is not limited to these embodiments unless otherwise specified in the following description. [Embodiment] An agitator according to an embodiment of the present invention will be described with reference to Figures 1 to 4. Figure 1 is a perspective view showing an agitator according to an embodiment of the present invention. Figure 2 is a diagram showing an agitator according to an embodiment of the present invention, where (a) is a partial front cross-sectional view showing a portion of the agitator in cross-section, and (b) is a right side view. Figure 3 is an enlarged exploded cross-sectional view showing an expanded state of part A in Figure 2(a). Figure 4 is an enlarged cross-sectional view showing part B in Figure 2(a). First, the configuration of the agitator 1 according to this embodiment will be explained with reference to Figures 1 and 2. The agitator 1, as its basic components, includes a stirring element 10 that agitates the object by rotating, a rotating shaft 20 to which the stirring element 10 is connected, a cylindrical cover 30 that covers the rotating shaft 20, a housing 40 that houses a driving means (not shown) for rotating the rotating shaft 20, and a gripping part 50 connected to the housing 40 for the operator to grasp. Furthermore, it includes a connecting body 60 that connects the cover 30 and the housing 40. The agitator 10 has a hub 11 attached to the tip of the rotating shaft 20 and blades 12 extending outward from the hub 11. The rotation of the blades 12 within the fluid being agitated stirs the fluid. The agitator 10 is configured to be detachably attached to the rotating shaft 20. The rotating shaft 20 is formed in a long cylindrical shape and is rotationally driven by a driving means to rotate the agitator 10 attached to its tip. The driving means, housed inside the casing 40, and the rotating shaft 20 are connected by a large-diameter cylindrical rotating shaft holder 21, which drives the rotating shaft 20 to rotate. The cover 30 is formed in a cylindrical shape and is positioned almost concentrically with the rotating shaft 20 so as to cover the rotating shaft 20 from the outside, with the outer circumference of the rotating shaft 20 being a predetermined distance from the inner surface 30a of the cover 30 (see Figure 2(a)). The upper end of the cover 30 is located slightly below the rotating shaft holder 21, and the lower end of the cover 30 is located slightly above the hub 11 of the agitator 10. Details of the positional relationship between the cover 30 and the agitator 10 will be described later. The presence of the cover 30 reduces the portion of the rotating shaft 20 that is exposed to the outside. To maintain the relative positional relationship with the rotating shaft 20, the cover 30
