Embodiment 1

[0019] In this example, see figure 1 with figure 2 A cleaning brush for a four-necked flask for emulsion synthesis, comprising a handle 1, a long and straight brush rod 2 and a brush head part, the brush rod 2 adopts a plastic rod, and the brush head part is installed on the front end of the brush rod 2, The tail of the brush rod 2 forms a handle 1. The brush head part is mainly composed of a suction cup 3 and a thin wire ball 8. The suction cup 3 is made of rubber material. The suction cup 3 is arranged at the front end of the brush rod 2. Conduction through the brush rod 2, so that the suction cup 3 is adsorbed on the inner wall surface corresponding to the bottleneck of the four-necked flask 9, which plays a very good role in stabilizing the flask. The thin wire ball 8 is set on the brush rod 2, and the fine The wire ball 8 can be deformed, and is provided with a deformation brush head expansion and contraction mechanism. The deformation brush head expansion and contracti...

Embodiment 2

[0023] This embodiment is basically the same as Embodiment 1, especially in that:

[0024] In the present embodiment, the front ends of each iron wire 5 are respectively articulated through independent small iron rings 7 and spring coils 6, which is convenient to manufacture and reduces the stress concentration and torque increase caused by the interaction between the small iron rings 7 and spring coils 6. When damage occurs, the connection relationship between the small iron ring 7 and the spring ring 6 is maintained, and the service life of the cleaning brush is improved.

Embodiment 3

[0026] This embodiment is basically the same as the previous embodiment, and the special features are:

[0027] In this embodiment, an auxiliary confinement ring that is enclosed within the brush rod 2 is set inside the thin wire ball 8, the outer ring size of the auxiliary confinement ring is smaller than the inner diameter of the bottle mouth of the four-necked flask 9, and the auxiliary confinement ring is in accordance with the sleeve mouth 4 They are arranged parallel to each other, and all the iron wires 5 pass through the inside of the auxiliary confinement ring. The auxiliary confinement ring makes most of the sections of the iron wire 5 in a straight working state, and only a part of the iron wire 5 in the thin iron ball 8 is in a bent working state, which is conducive to ensuring the maintenance of the stable working state of the iron wire 5 in force transmission.

Abstract

The invention discloses a cleaning hairbrush of an emulsion synthesis four-mouth flask; by virtue of an internal sucking disc device and thin iron wire balls which sleeve outside the internal sucking disc device, flexible iron wires are pulled and pushed, so that cleaning work is conducted. A long and straight hairbrush rod is connected to the upper part of a sucking disc; action force is exerted on a handle, so that the sucking disc is adsorbed on the bottom of the flask. The iron wires sleeve outside a sucking disc plastic rod, and the upper parts of the various iron wires are fixed to a sleeve opening while the lower parts are fixed to a spring ring by virtue of small iron rings, so that the spring ring is driven to do contraction and shrinkage motions by virtue of the iron wires. The thin steel wire balls are attached to the outermost periphery of the spring ring by a circle, so that the interior of the flask is cleaned. Firstly, the cleaning hairbrush disclosed by the invention is simple to operate and is convenient and practical, and the hairbrush is capable of brushing and cleaning the flask easily just by pushing and pulling the sleeve opening; secondly, the hairbrush is formed by contractible and shrinkable thin iron wire balls which are controllable in size, so that the inner wall of the flask can be cleaned and brushed thoroughly; and thirdly, the hairbrush is simple in design, low in manufacturing cost and is economical and practical, and the hairbrush is suitable for popularization and application in experimental processes.

Description

technical field [0001] The invention relates to a cleaning device for the inner wall of a container, in particular to a cleaning brush for a flask, which is applied in the technical field of chemical experiment instruments. Background technique [0002] A flask is a necked glassware that can withstand a certain amount of heat. It is also a very common laboratory glassware, usually made of heat-resistant glass. After using the flask, laboratory personnel must clean the flask in time, otherwise the residual product of the reaction will adhere to it and affect the subsequent use. Generally, flasks are divided into flat bottom and round bottom, the flat bottom is called flat bottom flask, and the round bottom is called round bottom flask. For the four-necked flask used for emulsion synthesis, the gel produced during the reaction often adheres to it after the experiment, which is difficult to clean. And because of the special structural design of the four-neck flask, it is also...
