Detailed Description
The invention will be further described with reference to the following examples and with reference to the accompanying drawings, it being understood that the following detailed description is only illustrative of the invention and is not intended to limit the scope of the invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the drawings, and the words "inner" and "outer" refer to directions toward or away from, respectively, the geometric center of a particular component.
The invention relates to a safe stirrer, which is shown in figure 1, and comprises a stirring barrel 1, an upper cover 2, a stirring shaft 3 and a motor 4; the stirring barrel 1 is of a cylindrical barrel-shaped structure with an opening at the upper part, the upper cover 2 is covered above the stirring barrel 1 and is matched with the stirring barrel 1 to form a closed accommodating space, a pressure relief hole 5 is formed in the side wall of the stirring barrel 1, a pressure relief nozzle 6 is arranged in the pressure relief hole 5, the pressure relief nozzle 6 is in interference fit with the pressure relief hole 5, a rubber recovery bag 7 is sleeved at one end of the pressure relief nozzle 6, which is positioned at the outer side of the stirring barrel, at least two elastic sheets 8 are arranged at one end of the pressure relief nozzle 6, the opening of the pressure relief nozzle 6 is completely covered by the elastic pieces 8, a sealing gasket 9 is arranged between the part, which is contacted with the stirring barrel 1 and the upper cover 2, a motor accommodating cavity 10 for accommodating a motor is additionally arranged in the upper cover 2, a motor 4 is arranged in the motor accommodating cavity 10, a driving shaft 3 at the lower end of the upper cover 2 is driven to rotate through gear engagement, and the stirring shaft 3 is arranged in the stirring barrel 1 and the stirring barrel is fixedly provided with stirring blades 11.
The principle of the invention is as follows: firstly, the sealing performance of the stirrer is guaranteed through the cooperation among the stirring barrel, the upper cover and the sealing gasket, wherein in order to avoid the influence of the gap between the stirring shaft and the upper cover on the sealing performance of the stirrer, a motor accommodating cavity is directly arranged in the upper cover, so that the sealing performance of the whole stirrer cannot be influenced even if a gap exists between the stirring shaft and the upper cover, the problem of air pressure rising in the stirring process is solved after the sealing performance is guaranteed, a pressure relief hole is formed in the side wall of the stirring barrel, a pressure relief nozzle is arranged in the pressure relief hole, one end of the pressure relief nozzle is sleeved with a rubber recovery bag which is flexible, the volume in the stirrer is indirectly increased, the air pressure is reduced, an elastic sheet is covered on the inner side of the pressure relief nozzle, and the pressure relief device is triggered only when the air pressure is high enough to influence the stirring effect in the stirrer, namely, the air is forced to enter the rubber recovery bag only when the air pressure is high enough to deform the elastic sheet. The material and the elastic coefficient of the elastic sheet can be changed according to the air pressure requirement of the stirring material.
As an embodiment of the present invention, the elastic sheet 8 has two pieces, and has the same shape and size, and is semicircular. Only two elastic sheets are used, so that the cost is saved, and the stress deformation of the elastic sheets is balanced.
