Description

A kind of fool proof filter cartridge construction

Technical field

The utility model is related to purifier fields, are specifically related to a kind of fool proof filter cartridge construction.

Background technology

As people are higher and higher to the hygienic requirements of drinking water, water purifier is in a variety of different occasions（Such as family, enterprise With some public places of entertainment etc.）Middle use is more and more extensive, in order to achieve the effect that best filtering, purification, it will usually in water purification The inside of device installs multiple filter cores and water is filtered for multiple times and purified treatment, is flowed into water tank stores for people later Drink.There is no error-proof structure between filter flask ontology and filter flask lid in the prior art, user be difficult determine whether to be installed in place, and Filter flask lid is once not installed in place the risk that can have leak, and in order to further meet the development need of purifier, having must The prior art is further improved.

Utility model content

The technical issues of the utility model is solved is to provide a kind of fool proof filter cartridge construction, to solve above-mentioned background technology In disadvantage.

The technical issues of the utility model is solved is realized using following technical scheme：

A kind of fool proof filter cartridge construction, including filter flask ontology and filter flask lid, filter flask lid are internally provided with internal thread, filter flask ontology Top is equipped with external screw thread, and filter flask lid is mounted on filter flask body upper part by way of being spirally connected, the lower part of the filter flask lid be equipped with The arc thin slice of filter flask ontology form fit, filter flask body upper part are equipped with the buckle of protrusion, and the centre of arc thin slice is equipped with buckle Hole,

When buckle coordinates clamping with block button hole, filter flask lid is installed in place with filter flask ontology；

Conversely, when buckle misplaces with block button hole, filter flask lid is not mounted to position with filter flask ontology.

Preferably, the arc thin slice is molded with filter flask lid for integral molded plastic.

The utility model is simple in structure, has very specific foolproof function, is filled again as not being screwed into position if not into machine, can be with Allow user there are one very clear intuitive information.

Description of the drawings

Fig. 1 is the structural schematic diagram of the utility model preferred embodiment；

Fig. 2 is the side view of the utility model filter flask lid preferred embodiment；

In figure, filter flask ontology 1, filter flask lid 2, arc thin slice 3, buckle 4, block button hole 31.

Specific implementation mode

In order to make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, under Face combines and is specifically illustrating, and the utility model is expanded on further.

Embodiment 1, referring to Fig. 1 --- shown in Fig. 2, a kind of fool proof filter cartridge construction, including filter flask ontology 1 and filter flask lid 2, filter Bottle cap 2 is internally provided with internal thread, and 1 top of filter flask ontology is equipped with external screw thread, and filter flask lid 2 is mounted on filter flask by way of being spirally connected 1 top of ontology, the lower part of the filter flask lid 2 are equipped with the arc thin slice 3 with 1 form fit of filter flask ontology, and 1 top of filter flask ontology is set There are the buckle 4 of protrusion, the centre of arc thin slice 3 to be equipped with block button hole 31,

When buckling 4 with the cooperation clamping of block button hole 31, filter flask lid 2 is installed in place with filter flask ontology 1；

Conversely, when buckling 4 with the dislocation of block button hole 31, filter flask lid 2 is not mounted to position with filter flask ontology 1.

Preferably, the arc thin slice 3 is molded with filter flask lid 2 for integral molded plastic.

The utility model in the lower part of filter flask lid 2 by being arranged the arc thin slice 3 with block button hole 31, on filter flask ontology 1 Portion's setting buckle 4, buckle 4 must coordinate with block button hole 31 can just be screwed into position.Otherwise as when not being screwed into, buckle 4 will jack up The arc thin slice 3 that filter flask covers, such arc thin slice 3 pushed up outward when being higher by filter flask ontology 1, then filter flask can not be installed to machine On device, the utility model is simple in structure, has very specific foolproof function, is filled again not into machine, Ke Yirang if not being screwed into position There are one very clear intuitive information by user.

The advantages of basic principles and main features and the utility model of the utility model have been shown and described above.One's own profession The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model Claimed range is defined by the appending claims and its equivalent thereof.
