Description

Double-material integrated mixing barrel

Technical Field

The application relates to the technical field of solid-liquid mixing devices, in particular to a double-material integrated mixing barrel.

Background

The disinfection is mainly used for eliminating and killing pathogenic bacteria floating in the air of a place or attached to articles, and the disinfection of public places can improve the sanitary condition of places and prevent diseases from happening and popularizing, is an important action for improving the sanitary condition of public places, and can effectively ensure the health and safety of the public.

The requirements of places with large flow and dense flow of people such as catering industry, medical institutions and the like on field sanitation conditions are higher, and in order to meet the related requirements of sanitation departments and better ensure public safety, the corresponding places are required to be disinfected timely and thoroughly. The common disinfection measure is to intermittently spray disinfection solution to public facilities or the air in public space, the preparation of the disinfection solution is usually carried out according to the steps of firstly measuring and then mixing, and after quantitatively measuring disinfection solvent according to the requirement, the disinfection solvent is added into quantitative solute for mixing to obtain the standard disinfection solution. Generally, the disinfectant is mainly prepared at present, an operator needs to finish the mixing preparation work on a disinfection site, but as the disinfectant has certain irritation and corrosiveness, and strong pungent smell can be emitted at the moment of mixing and preparing solid-liquid materials when the solid-liquid materials are mixed and prepared in an open environment, even if the operator wears protective tools such as masks, gloves and the like, the occurrence of unexpected risks cannot be completely blocked, and the gas can cause serious damage to human respiratory tracts and organs by long-term inhalation from mouths and noses, the preparation mode of the on-site manual preparation is complex in procedure and has great potential safety hazard.

Some devices capable of mixing solid and liquid in a relatively closed environment are also disclosed in the prior art, such as a beverage bottle cap capable of adding solid solute disclosed in Chinese patent CN 208683460U, which comprises an outer cap and an inner plug, wherein the inner plug is sleeved inside the outer cap, a gap between the outer cap and the upper end of the inner plug is closed, the top of the inner plug is provided with an arc-shaped top, the arc-shaped top is a soft silica gel thin wall plate, two arc-shaped inner lining plates are symmetrically arranged inside the arc-shaped top, the two inner lining plates are respectively connected with the arc-shaped top through connecting columns, and the lower end surfaces of the inner lining plates are uniformly provided with saw teeth; the solid solute is packaged in the inner plug, so that solid-liquid separation before mixing can be realized, when the inner plug is in formal use, the arc-shaped top is pressed firstly to drive the saw teeth at the lower end of the inner lining plate to puncture the lower end packaging paper, so that the solute in the inner plug is mixed with the solvent contained in the bottle in advance, at the moment, the bottle cap is not opened, and the bottle is in a sealing state. Therefore, if the container is used for solid-liquid mixing, even if the mixing process emits irritating gas, the gas will not leak out. However, there are several disadvantages to formulating a disinfectant using such containers: 1. the packing paper is a non-recoverable structure, so that the device can not realize the fractional release of the solute, and can only be used in one-time mixing operation; 2. the arc-shaped top is a soft silica gel thin wall plate, belongs to an elastic structure, and has the possibility of false touch release under the condition that other protective structures are not present, so that the effect of current preparation and use can not be achieved; 3. because the packaging paper belongs to an irrecoverable structure, the container can only be used once, and the cost is high.

From the above, some solid-liquid mixing devices disclosed in the prior art are mainly used for storing solute and solvent separately in advance to achieve the effects of dampproofing, moisture proofing and prolonging the preservation period of the solvent, the mixing process is usually completed once, the solute or solvent cannot be put in a separated manner, and once the membrane structure such as packaging paper is damaged by the stab component, the container cannot be recycled again, so that the container belongs to a disposable structure, and the use cost is relatively high.

Therefore, a novel solid-liquid mixing container for preparing disinfectant is necessary to be developed, so that the independent storage of solutes and solvents before mixing can be realized, and the airtight mixing of the solutes and the solvents can be realized, so that the outward dispersion of toxic and harmful gases can be prevented, and the physical health of operators can be fully ensured; the release process of the solvent or solute is controllable, so that the batch and repeated release and allocation process can be realized; preferably, the container matrix structure is not damaged in the use process, so that the recycling of the container is conveniently realized, and the use cost can be effectively controlled.
