Description

Technical Field

[0001] The utility model relates to the technical field of cleaning tools, mainly for cleaning experimental glassware, and specifically is a novel multi-purpose glass container cleaning device. Background Art

[0002] Laboratory bottles are a type of glass container commonly used in scientific research laboratories, usually used to hold, mix or react chemical substances. There are many different types of laboratory bottles, among which the most common ones include volumetric flasks, conical flasks, round-bottom flasks, etc. Taking the volumetric flask as an example, the volumetric flask is a common test bottle in the laboratory. Its main features are a wide bottom and a large capacity. It is generally spherical or conical, and is usually used for operations such as solution mixing and dilution; volumetric flasks are divided into narrow-mouth volumetric flasks and wide-mouth volumetric flasks. Narrow-mouth volumetric flasks are generally used to accurately measure and dilute small amounts of liquids, while wide-mouth volumetric flasks are more suitable for dissolving solids or liquids. Conical flasks are usually used to collect gases because their tip shape facilitates gas collection and observation of gas production. The reason why laboratory bottles have a variety of shapes is that different experimental operations require different experimental purposes, different processes, and many other requirements, which lead to the need to use bottles of various shapes.

[0003] However, this type of glass container is difficult to clean due to the narrow and long structure of the bottle mouth, which is a common pain point in the industry. Conventional cleaning brushes need to be completely cleaned, which makes the cleaning process inconvenient and inefficient. This is mainly because the bottle mouth is narrow and long, and it is difficult to use ordinary cleaning tools such as brushes to enter the deep part of the bottle mouth for cleaning. Due to shape adaptation problems, the cleaning is incomplete and residual substances are easily left. In order to solve this problem, a specially designed bottle mouth brush can be used or a solvent or a more expensive ultrasonic cleaning equipment can be used for cleaning. Taking the volumetric flask cleaning device disclosed in Chinese Patent 202221821875.4 as an example, it discloses the cleaning of spherical container bottles, but this structure is too simple and cannot clean containers such as conical flasks. Although some cleaning devices have multi-functional and multi-angle cleaning functions, they are generally complex in structure and have high preparation costs. Summary of the invention

[0004] In order to solve the deficiencies of the above-mentioned prior art, the inventor has developed and designed a new multi-purpose glass container cleaning device, which has the function of cleaning glass containers of various shapes, and can use a multi-level adjustment method according to actual use needs to achieve structural adaptation to different bottle types, thereby improving applicability, cleaning efficiency and cleaning quality. Specifically, the utility model is implemented as follows:

[0005] A novel multi-purpose glass container cleaning device comprises a cleaning rod and a brush bar with bristles installed at the end of the cleaning rod. The core of the structural design is:

[0006] An end piece, mounted on the end of the cleaning rod;

[0007] The sliding sleeve is composed of two split half sleeves, including a first sliding half sleeve and a second sliding half sleeve, which are respectively sleeved on the cleaning rod and can slide up and down along the cleaning rod, and the tail of each sleeve is respectively installed with an elastic limiting pressing piece;

[0008] The brush bar is divided into an arc brush bar group and a two-section brush bar group, wherein:

[0009] The arc brush strip group is composed of a plurality of arc brush strips, one end of which is mounted on one half of the end piece, and the other end is mounted on the tube end of the first sliding half sleeve, and the arc brush strips are slightly bent outwards under normal conditions; when the arc brush strip group is squeezed by the axial force of the cleaning rod, it can expand outwards and bulge into a hemispherical structure;

[0010] The two-section brush strip assembly comprises a plurality of two-section brush strips, one end of which is mounted on the other half of the end piece, and the other end is mounted on the tube end of the second sliding half sleeve, and each section of each two-section brush strip is hingedly connected; when the two-section brush strip assembly is squeezed by the axial force of the cleaning rod, it can expand and bend outward to form a semi-conical structure;

[0011] The limit slots are in two groups and are longitudinally arranged on both sides of the cleaning rod along the length direction of the cleaning rod. The shape of the limit slots is adapted to the pressure head of the limit pressing piece, so that under normal conditions, the pressure head of the limit pressing piece can be inserted into a limit slot due to its own elasticity to lock the relative position of the first sliding half-sleeve or the second sliding half-sleeve relative to the cleaning rod.

[0012] The working principle of the utility model is introduced as follows: the multi-purpose glass container cleaning device of the utility model can be set with various models and sizes according to the total length of the cleaning rod, such as large, medium and small, so as to be suitable for volumetric flasks or experimental bottles with different lengths of bottle mouths. According to the different lengths, the lengths of the first sliding half-tube and the second sliding half-tube and the position design of the limit pressing piece all need to be adjusted accordingly, but the overall design structure remains unchanged. Taking the average size as an example, the length of the cleaning rod is basically longer than the overall height of the volumetric flask. Under normal conditions, the first sliding half-tube and the second sliding half-tube are in the initial position, that is, the storage state. The first sliding half-sleeve tube is in an active state, and a thrust is applied to press it downward, so that the first sliding half-sleeve tube slides downward along the cleaning rod, shortening the cleaning time and then sliding the brush bar as close to the cleaning rod as possible. The distance between the end of the cleaning rod and the first sliding half-sleeve is adjusted, and the arc-shaped brush strip installed between the end of the cleaning rod and the first sliding half-sleeve is expanded outward into an arc shape by the extrusion force. The shape of the arc-shaped brush strip is controlled by the degree of downward pressure, so that it can adapt to the curvature of the inner wall of the volumetric flask and can contact it. Then release the limit pressing piece, the limit pressing piece resets under the action of its own elastic force, and the end of the pressing piece moves downward and is inserted into the limit card groove on the cleaning rod corresponding to the current position, thereby locking the current position of the first sliding half-sleeve and keeping the arc-shaped brush strip in the expanded state. At this time, you can hold the end of the cleaning rod and rotate it to drive the arc-shaped brush strip to move. The brush strips rotate accordingly, thereby achieving the purpose of conveniently cleaning the inner wall of the spherical volumetric flask; when it is necessary to clean a conical flask or other container bottles with obvious angled edges, the limiting pressing piece on the second sliding half sleeve can be pressed to push the second sliding half sleeve downward, and the two sections of the brush strips will form an inflection point at the hinge point due to the pressure change caused by the displacement and expand outward to form a turning structure similar to an acute angle, and the two sections of the brush strips respectively constitute two bevel structures, the bottom bevel is used to clean the bottle bottom, the upper bevel is used to clean the bottle wall, and the convex corner of the turning part can be used to clean the bottom edge of the volumetric flask and other corners.

[0013] Beneficial technical effects of the utility model: The utility model has a scientific and reasonable structure, a streamlined design and a double brush bar structure. The arc-shaped brush bar can form a relatively smooth arc-shaped structural surface, which can be suitable for the cleaning of spherical or arc-edged volumetric flasks. It can also use a conical brush bar structure with convex corners composed of two sections of brush bars, which can be suitable for the cleaning of some volumetric flasks or test bottles with corner edges, that is, one device can be adapted to the cleaning function of volumetric flasks of various shapes, and there is no need to frequently replace the cleaning brush during the cleaning process, thereby improving the cleaning efficiency and user experience. It also has a multi-speed adjustment function, which can fix the unfolding shape and degree of the brush bar and keep it fixed according to actual use needs, thereby improving the brush angle control during cleaning, adapting to the bottle shape as much as possible, and sticking to the bottle wall to improve the cleaning efficiency and quality.

When removing or installing the first sliding half sleeve 21 and the second sliding half sleeve 22, the end piece 12 needs to be removed, and the end piece 12 can usually be installed at the end of the cleaning rod 11 using screws or threaded structures; the two sets of inserts 24 on the first sliding half sleeve 21 and the second sliding half sleeve 22, each insert 24 is arranged along the radial direction of the cleaning rod 11, so that it cannot fall off after being inserted. In this structure, the slots 13 are arranged in a uniform and symmetrical cross shape, and the two inserts 24 form an oblique narrow structure with each other. After insertion, they cannot fall off the cleaning rod 11 in the horizontal direction, and no additional fixing parts are required for locking, and they can slide freely.

[0045] Preferably, the structure of the two-section brush strip 32 includes an upper brush strip 321 and a lower brush strip 322. One end of the upper brush strip 321 is fixedly or hingedly mounted on the tube end of the second sliding half sleeve 22, and the other end is hingedly connected to one end of the lower brush strip 322. The other end of the lower brush strip 322 is hingedly mounted on the terminal piece 12, and the upper brush strip 321 is longer than the lower brush strip 322. The brush strip 30 can be made of elastic plastic material or a metal wire rod structure. A hinge structure can be installed between the upper brush strip 321 and the lower brush strip 322, or two rings can be nested to form a connection; preferably, if a hinge is used, the hinge structure between the lower brush strip 322 and the upper brush strip 321 is set as a unidirectional outward 180° rotating hinge to prevent reverse bending, that is, reverse bending when pressed, which needs to be avoided in design. The lower brush strip 322 can be originally tilted outward. Preferably, the end piece 12 may be provided with an inwardly recessed groove at the fixing point where the two sections of the brush strips 32 are installed, the fixing point being placed at the bottom of the groove, and the groove wall can prevent the two sections of the brush strips 32 from tilting inwards and preventing them from bending in the reverse direction. The groove wall can prevent the lower brush strip 322 from shifting in the reverse direction, thereby ensuring that it can only tilt and unfold outwards under pressure.

[0046] Preferably, the limiting pressure piece 23 includes a pressing plate 231 and a fulcrum seat 233. The fulcrum seat 233 is fixedly mounted at the end of the tube body of the first sliding half-sleeve 21 and the second sliding half-sleeve 22. The torsion spring is mounted on the fulcrum seat 233.

When the end of the pressing plate 231 is pressed, the torsion spring is squeezed and the front end is disengaged from the limiting slot 15, releasing the restrictions of the first sliding half-sleeve 21 and the second sliding half-sleeve 22. In the above structure, the torsion spring structure can be removed, and a bent elastic sheet with a self-contained spring property can be fixedly installed at the tail end of the pressing plate 231 to form a structural design of this function. The fulcrum seat 233 acts as a lever fulcrum, and the spring can be well reset when subjected to pressure and when the pressure is released.

[0047] Preferably, the brushes on the brush strip 30 are distributed in a spiral shape or evenly distributed in a shape expanding around the brush strip 30 .

[0048] Preferably, a handle 14 is installed at the tail end of the cleaning rod 11 to facilitate the operator to hold and apply force during the cleaning process.

[0049] Preferably, a brush is provided on the outer side of the end piece 12. Since the end of the cleaning rod 11 usually contacts the bottom surface of the bottle, some brushes are designed and installed above it to achieve a cleaning effect.

[0050] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation on the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
