Embodiment 1

[0021] In order to solve the problem of inconvenient cleaning of the round bottom flask existing in the prior art, the present embodiment provides a method such as figure 1 The scrub head shown is a collapsible round bottom flask cleaning brush. The cleaning brush includes a cleaning rod 1 , a fixed connector 2 and a brush head 3 , one end of the fixed connector 2 is fixed to the cleaning rod 1 , and the other end is fixed to the brush head 3 . Bristles 4 are fixed on the brush head 3 . The bristles 4 are made of nylon or polyester fiber.

[0022] The fixed connector 2 is cylindrical, and a U-shaped groove 5 is opened axially upward from the bottom surface at its lower end, and the axis of the U-shaped groove 5 coincides with the axis of the fixed connector 2 . Such as figure 2 shown.

[0023] There are two brush heads 3 with exactly the same shape and structure. The brush heads 3 are arc-shaped, and the center of the arc is upward; In the groove 5; the two brush heads 3...

Embodiment 2

[0026] On the basis of Embodiment 1, the brush head 3 of the round-bottom flask cleaning brush of the present embodiment is an arc-shaped structure composed of bristles 4 and twisted wires for fixing the bristles. The metal wire is selected from a metal wire with a certain softness, such as iron wire, aluminum wire or other alloy wires.

[0027] The two brush heads 3 of the round bottom flask cleaning brush of the present invention can rotate around the fixed shaft 6 to realize the opening and folding of the brush heads. Entering, when entering the bottom of the flask, the two brush heads 3 can be separated by pressure and attached to the inner wall of the flask, and the inner wall of the flask can be scrubbed clean by rotating the brush head.

Abstract

The invention relates to a round-bottom flask cleaning brush with foldable washing and brushing heads. The round-bottom flask cleaning brush comprises a cleaning rod, a cylindrical fixed connector andtwo washing and brushing heads, one end of the fixed connector is fixed with the cleaning rod, the other end of the fixed connector is fixed with the washing and brushing heads, a U-shaped groove isaxially formed in the lower end of the fixed connector from the bottom surface upwards, an axis line of the U-shaped groove is coincident with that of the fixed connector, one end of one washing and brushing head is coincided with one end of the other washing and brushing head each other, the washing and brushing heads are fixed into the U-shaped groove through a fixed shaft, the washing and brushing heads and the cleaning rod rotate around the fixed shaft in the same plane, and the washing and brushing heads are limited through the bottom of the U-shaped groove. The two washing and brushing heads can rotate around the fixed shaft, unfolding and folding of the washing and brushing heads are achieved, the two washing and brushing heads are coincided together each other when entering and exiting from an opening of a round-bottom flask and smoothly enter the round-bottom flask, the two washing and brushing heads are separated by the aid of pressure when entering the bottom of the round-bottom flask, the washing and brushing heads are fitted with the inner wall of the round-bottom flask, and the inner wall of the round-bottom flask can be brushed and washed up.

Description

technical field [0001] The invention relates to a cleaning device for glassware, in particular to a cleaning brush for a round bottom flask with a foldable cleaning head. Background technique [0002] The test tube brush is mainly used to clean glassware in the laboratory. Because the test tube brush is straight, it is usually very convenient for cleaning straight vessels, but it is often difficult to clean when cleaning non-straight vessels such as round bottom flasks and Erlenmeyer flasks. Laborious and easy to clean. [0003] Especially when doing some experimental reactions with strong product adhesion, and using larger round bottom flasks of 5L and 10L, some residues that are difficult to remove by washing with water will adhere to the wall of the round bottom flask, while Because the common straight test tube brush can only brush near the bottom; even if the special bottom bristle of the flask is a fan-shaped brush, it is difficult to touch the upper position of the i...
