Embodiment 1

[0017] Example 1. see Figure 1a and Figure 6g : The horizontal section of the barrel body 1 is a narrow waist circle, the bottom surface 2 of the barrel extends horizontally on both sides of the width of the barrel body 1, and the barrel product is obtained by one-time injection molding. The weak point of this example product is that a part of the teacher's hand washing water may spill out of the bucket due to the narrow mouth of the bucket 3 .

Embodiment 2

[0018] Example 2. see Figure 1b and Figure 6f : the bottom of the barrel body 1 is smaller and the barrel mouth 3 is larger, any horizontal section thereof is rectangular, and two groups of opposite sides are straight planes. The bottom surface 2 of bucket is the same as example 1. When the area of ​​the inner bottom of the bucket is equal, the mouth surface of the bucket product of this example is larger than that of the bucket product of Example 1, thereby reducing the possibility of handwashing water spilling outside the bucket, but the mold structure is complex, and the processing difficulty is greater than that of Example 1.

Embodiment 3

[0019] Example 3. see figure 2 and Figure 3d : The bucket product is spliced ​​together by injection molding the barrel body and the bottom of the barrel (the splicing surface is bonded by strong adhesive). The bucket body is still small at the bottom and big at the top, but two sets of opposite sides are curved surfaces turned outward, and any horizontal section of the bucket body 1 is still rectangular.

Abstract

The invention discloses a special barrel for cleaning a classroom, relating to the field of school classroom supplies. The special barrel comprises a barrel body, a barrel lifting handle and the like, wherein the barrel body can be formed by splicing a barrel body piece and a barrel bottom piece, the barrel body has a narrow type horizontal section, at least one pair of opposite side surfaces are expanded outwards from bottom to top, and the bottom surface of the barrel extends horizontally on the two sides of the width of the barrel body. The wider mouth surface of the barrel is favorable for collecting water which is trickled down by a teacher during hand-washing, the falling water is constrained by the narrower barrel body to get the appropriate depth so as to be suitable for rinsing by flat brooms and mops, and the wider barrel bottom piece can ensure the stability in the use of the barrel body. The application of the cleaning barrel is favorable for improving the management of school classroom internal affairs.

Description

technical field [0001] The invention relates to a daily necessities which can be used in classrooms of primary and middle schools, that is, a special barrel for cleaning classrooms. Background technique [0002] At present, there are always dirty brooms and mops piled up in one corner of the classrooms of primary and secondary schools (it can be said that sanitary tools are unhygienic).
