Description

Easy-to-detach filter flask

Technical Field

The utility model relates to a filter flask of a water purifier, in particular to an easy-to-detach filter flask.

Background

The applicant of the present application applies for a new TWM501883U patent in taiwan, and provides a leakage-proof structure for combining a bottle body and a bottle cap of a filter bottle of a water purifier, which is provided with a concave portion on a thread of an external thread at the top of the bottle body of the water purifier, and a protruding portion on a thread of an internal thread of the bottle cap, wherein the protruding portion is clamped into the concave portion, so that a water hammer effect generated during water pressure change can be resisted, and loosening and displacement of the bottle body and the bottle cap can be effectively prevented.

Most of water purifiers are arranged below the wash stand, so that when the filter flask is detached and replaced, the filter flask is required to be bent down or replaced in a kneeling mode, but the filter flask detached and replaced in a screw locking mode can be separated from the bottle cover with more effort.

Based on the above-mentioned shortcomings, the present utility model aims to provide a filter flask of a water purifier, in particular to an easy-to-detach filter flask.

According to the above-mentioned purpose, the utility model provides an easy-to-detach filter flask, comprising a flask body and a flask cover, wherein a flask neck of the flask body is provided with at least three limiting blocks which are arranged at intervals and protrude from the surface of the flask neck, and at least three limiting structures are correspondingly arranged at one side of the at least three limiting blocks, and the inner surface of the flask cover is provided with a plurality of clamping blocks matched with the outline of the at least three limiting structures.

Each of the limiting structures is provided with a positioning part, and each clamping block is provided with a clamping part matched with the contour of the positioning part.

Wherein the bottleneck and a body of the bottle body are integrally formed or welded with each other.

The bottle cap is also provided with a ring body sleeved on the outer surface of the bottle cap.

Wherein the ring body is a metal ring.

Wherein the bottle body and the bottle cap are made of metal materials or plastic materials.

Each limiting block is provided with a guide part and a limiting wall, wherein the limiting wall extends downwards from one end of the guide part, and the guide part and the limiting wall jointly define the limiting structure on the surface of the bottleneck.

The utility model increases the structural stability between the bottle cap and the bottle body by arranging the positioning part, and avoids the loosening of the bottle body caused by the water hammer effect. By arranging the limiting block, a user can detach the bottle body and the bottle cap with less force, and the use convenience is improved.

Detailed Description

In order to clearly illustrate the embodiments, constructions and effects achieved by the present utility model, examples are now provided and described with reference to the accompanying drawings as follows:

The description of the directions of "front", "rear", "upper", "lower" and the like in the present utility model is merely for convenience of understanding, and the present utility model is not limited to these directions but may be adjusted according to actual circumstances. Referring to fig. 1 to 2, the present utility model provides an easy-to-detach filter flask, comprising a flask body and a flask cap 20, wherein a receiving space is provided in the flask body for receiving a filter element, a bottleneck 15 of the flask body extends upward from one end of a flask body 12, the bottleneck 15 has three stoppers 16 disposed on an outer surface of the bottleneck 15 at intervals, wherein each stopper 16 protrudes from the outer surface of the bottleneck 15, each stopper 16 has a guiding portion 162 and a stopping wall 161, the stopping wall 161 extends downward from one end of the guiding portion 162, the guiding portion 162 and the stopping wall 161 together form a limiting structure 18 on the surface of the bottleneck 15, and each limiting structure 18 is provided with a positioning portion 17. Wherein the inner surface of the bottle cap 20 is provided with a plurality of clamping blocks 21 matched with the outlines of the limiting structures 18. In other embodiments, the number of the limiting blocks 16 may be more than three, preferably four to five. Wherein the neck 15 and a body 12 of the bottle are integrally formed or welded to each other by ultrasonic welding or the like.

In the embodiment of the present utility model, the end of the guiding portion 162 of the limiting block 16 far from the stopping wall 161 is further provided with a guiding inclined plane 162a, when a user wants to combine the bottle cap 20 with the bottle body, the engaging block 21 of the bottle cap 20 enters the limiting structure 18 along the guiding inclined plane 162a until the engaging block 21 contacts the stopping wall 161 of the limiting block 16, and the assembling of the bottle cap 20 and the bottle body is completed.

To further illustrate, each of the engaging blocks 21 has an engaging portion 211 matching the contour of the positioning portion 17. In the embodiment of the utility model, the positioning portion 17 is a bump, and the engaging portion 211 is a groove. In other embodiments, the engaging portion 211 may be a bump, the positioning portion 17 may be a groove, or the engaging portion 211 and the positioning portion 17 may be other concave-convex matching structures.

Because the flow of water has inertial momentum, the bottle cap 20 and the bottle body may be loosened, thereby affecting the operation of the water purification system. The positioning part 17 is arranged to increase the structural stability between the bottle cap 20 and the bottle body, and the bottle body is prevented from loosening due to the water hammer effect. By arranging the limiting block 16, a user can detach the bottle body and the bottle cap 20 with less force, and the use convenience is improved.

In addition, the filter bottle of the utility model is also provided with two sealing rings 19 sleeved at the ends of the bottle neck 15 above the limiting blocks 16, which can increase the structural stability between the bottle cap 20 and the bottle body and prevent water leakage.

Further, the bottle cap 20 and the bottle body may be made of metal materials, or made of plastic materials, or the bottle cap 20 is made of metal materials, the bottle body is made of plastic materials, or the bottle cap 20 is made of plastic materials, and the bottle cap is made of metal materials.

Referring to fig. 3, in a second embodiment of the present utility model, a ring 25 is provided to be sleeved on the outer surface of the bottle body, the ring 25 is a metal ring, and the structural strength between the bottle cap 20 and the bottle body can be enhanced by the ring 25 to prevent the bottle cap 20 from being released from the bottle body.

The utility model is characterized in that the limiting block 16 is arranged to form the limiting structure 18 on the surface of the bottleneck 15 and the clamping block 21 is arranged on the bottle cap 20, so that a user can separate the bottle body from the bottle cap 20 with less force, and the operation convenience is improved. In addition, the positioning part 17 increases the structural stability between the bottle cap 20 and the bottle body, and prevents the occurrence of water hammer effect.
