Description

Multifunctional volumetric flask brush

Technical Field

The utility model belongs to the technical field of experimental equipment, and particularly relates to a multifunctional volumetric flask brush.

Background

The volumetric flask is the glassware that often can use in the laboratory for the constant volume of solution is placed, and volumetric flask is used the back and is to be washd for follow-up use, and current brush that is used for volumetric flask abluent usually adopts ordinary test tube brush or oval brush head and triangle-shaped brush head, and the brush that above-mentioned structure set up exists the too big or too little problem of brush head, and there is the problem that volumetric flask is inside washly not put in place at a bit more, and current brush that is used for volumetric flask abluent is mostly with brush hair direct fixation on the brush pole, pours the lotion into volumetric flask in, washs with the brush, washes with water at last, and this kind of operation has the cleaning time long, the great problem of loss.

Disclosure of Invention

Aiming at the problems in the background technology, the utility model aims to provide a multifunctional volumetric flask brush which is realized by the following technical scheme:

a multifunctional volumetric flask brush, the volumetric flask brush comprising:

hollow handle: the handle part is provided with a hollow columnar lower connecting end and a bell-mouth-shaped handle part with the diameter gradually becoming larger from the lower connecting end upwards;

middle brush: the hollow columnar structure is characterized in that two ends of the hollow columnar structure are threaded connection parts, and bristles are uniformly distributed on a pipe body between the threaded connection parts;

bottom brush: the brush comprises a hollow columnar upper connecting end and a bottom brush part with a triangular cross section extending downwards from the upper connecting end, wherein bristles are uniformly distributed on the outer wall of the bottom brush part, and the bottom edge of the bottom brush part is of a folding structure.

Further, two ends of the middle brush are respectively connected with the lower connecting end of the hollow handle and the upper connecting end of the bottom brush in a threaded manner.

Further, a hose is sleeved on the handle part of the hollow handle, and the other end of the hose is connected with the faucet.

Further, a plurality of water outlet holes are uniformly distributed on the tube body of the brush and the bottom of the bottom brush.

Further, external threads are arranged at two ends of the middle brush, and internal threads matched with the external threads are arranged at the lower connecting end of the hollow handle and the upper connecting end of the bottom brush.

Further, the cross section of the bottom brush is isosceles triangle.

According to the utility model, the disassembly and connection of the volumetric flask brush are realized through the split type hollow handle, the middle brush and the bottom brush, the volumetric flask brush is convenient to clean, the whole hollow structure is convenient to connect with the faucet directly through the hose, water flows out of the interior of the volumetric flask brush, the purpose of rapid cleaning is achieved, and meanwhile, the bottom can be folded, so that the corner part of the volumetric flask can be thoroughly cleaned.

fig. 1-hollow handle, 101-handle portion, 2-middle brush, 3-bristles, 4-bottom brush, 401-bottom brush part, 5-hose and 6-water outlet hole.

Detailed Description

The utility model is further described below in conjunction with the drawings of the specification to better understand the technical scheme.

As shown in fig. 1, the multifunctional volumetric flask brush of the present utility model comprises a hollow handle 1, a middle brush 2 and a bottom brush 4 which are sequentially connected from top to bottom, wherein the hollow handle 1 is provided with a hollow columnar lower connecting end and a bell-mouth-shaped handle part 101 with the diameter gradually becoming larger and extending upwards from the lower connecting end; the lower connecting end is mainly used for being connected with the middle brush 2, the handle part 101 is used for holding, the handle part 101 is in a horn mouth shape, washing liquid is convenient to add from the opening end of the handle part 101, meanwhile, the hose 5 can be sleeved, the other end of the hose 5 is connected with a faucet, water of the faucet is convenient to directly enter the volumetric flask brush, and the cleaning efficiency is improved.

The middle brush 1 is of a hollow columnar structure, two ends of the middle brush are threaded connection parts, and bristles 3 are uniformly distributed on a pipe body between the threaded connection parts; the bottom brush 4 is provided with a hollow columnar upper connecting end and a bottom brush part 401 with a triangular cross section extending downwards from the upper connecting end, preferably, the bottom brush part 401 is in an isosceles triangular shape, bristles 3 are uniformly distributed on the outer wall of the bottom brush part 401, the bottom edge of the bottom brush part 401 is of a folding structure, the folding structure is similar to a folding fan, the bottom of the bottom brush part is in a stretching state in a natural state, when the bottom brush part needs to be placed into a volumetric flask for cleaning, external force is slightly applied to retract the bottom of the bottom brush part, then the bottom of the volumetric flask stretches into the mouth of the volumetric flask, and after the bottom of the bottom brush part breaks away from the external force, the bottom of the volumetric flask is automatically unfolded, and the bristles 3 are adhered to the bottom and the periphery of the volumetric flask to realize dead angle-free cleaning.

The concrete relation of connection of well handle 1, well brush 2 and end brush 3 is, the both ends of well brush 2 respectively with the lower link of well handle 1 and the last link threaded connection of end brush 4, be provided with the external screw thread on the both ends of well brush 2 in particular, all be provided with the internal thread with the external screw thread adaptation on the lower link of well handle 1 and the last link of end brush 4, realize connecting through the internal and external screw thread, simultaneously on the body of well brush 2 and the bottom equipartition of end brush 4 be provided with a plurality of apopores 6, the setting of apopore 6 realizes the action of flushing while brushing, improves abluent efficiency.
