Abstract

The utility model discloses an air insulating and clean keeping purified water bottle which is used for a water drinking machine. The utility model is composed of a bottleneck, an enlarging part, an air insulating film, a bottle bottom, and bottle body. After the utility model is filled with water, a bottle opening is downwards arranged on the water drinking machine. When the water in the utility model flows in the water drinking machine, the air insulating film in the bottle can be automatically shrunk, and air can not enter the bottle. The utility model has the advantages of avoiding harmful substances in the air polluting purified water and guaranteeing that the purified water in the bottle is not polluted in the course of use.

Description

The trapping pure water bottle of keeping a public place clean

The utility model relates to a kind of pure water container, the pure water bottle that uses on especially a kind of automatic water-drinking machine.

(general capacity is 18.9 liters to the pure water bottle that uses on the water dispenser at present, 5 gallons), bottleneck is installed on the water dispenser downwards behind this bottled full water, when the water in the bottle flows out water dispenser, air will enter in the pure water bottle by water dispenser, makes pure water in the bottle will be subjected to the pollution of harmful substance in the air.

In view of above-mentioned the deficiencies in the prior art, the purpose of this utility model is that a kind of trapping pure water bottle of keeping a public place clean will be provided.This bottle in use, it can prevent effectively that air from entering in the pure water bottle, avoids in the air harmful substance to pollute pure water.

The purpose of this utility model is achieved in that separates a following enlarged of bottleneck and a bottle end with body, enlarge trapping film on mouthful installed inside at place at bottleneck, and trapping film and bottleneck expansion mouth will be connected firmly closely knit, not blank gas.At the bottom of installing bottle in the outside of trapping film with the body part, and enlarge the mouth screwed connection with bottleneck, connect and be installed on the water dispenser downwards when the trapping that the fill water pure water bottle bottleneck of keeping a public place clean, when the pure water in the bottle flows out, trapping film in the bottle will shrink automatically, avoid air to enter in the bottle, reach the not contaminated purpose of pure water.

The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is according to the keep a public place clean profile of pure water bottle of the trapping that the utility model proposes.

Describe details and working condition in detail below in conjunction with Fig. 1 according to the concrete device that the utility model proposes.

This device comprises a bottleneck and following enlarged (1), there is trapping film (2) the bottle inboard, the trapping film will be connected closely knit firm with bottleneck and following enlarged, the skin of trapping film be bottle at the bottom of and body (3), bottle is reserved passage (4) at the end, divide (3) to use screwed connection with body and bottle bottom bottleneck and following enlarged (1), be installed on the water dispenser (5) after filling water in the bottle, when the valve of opening on the water dispenser (6), the trapping film (3) when water flows out in the bottle will shrink automatically and reach air and can not enter into a purpose in the bottle.

Claims

A kind of trapping pure water bottle of keeping a public place clean, the pure water bottle that particularly uses on the water dispenser, it is characterized in that it is grouped into by bottleneck and enlarged, trapping film, body and bottom, the following enlarged of bottleneck was separated with body with the bottle end, enlarge trapping film on mouthful installed inside at place at bottleneck, trapping film and bottleneck expansion mouth will be connected firmly closely knit, not blank gas, with the body part, and enlarge with bottleneck and mouthful firmly to be connected at the bottom of installing bottle in the outside of trapping film.
