Description

Easy-to-detach filter bottle

Technical Field

The utility model relates to a filter bottle of a water purifier, in particular to an easily detachable filter bottle.

Background technique

The Taiwan New Patent No. TWM501883U applied by the applicant in this case provides a leak-proof structure for the combination of the bottle body and the bottle cap of a water purifier filter bottle. The structure is such that a recessed portion is provided on the thread of the external thread on the top of the bottle body of the water purifier, and a protrusion is provided on the thread of the internal thread of the bottle cap. The structure in which the protrusion is inserted into the recessed portion can resist the water hammer effect generated by changes in water pressure, and effectively prevent the bottle body and the bottle cap from loosening and shifting.

Since most water purifiers are installed under the sink, you need to bend over or kneel to replace the filter when replacing the filter bottle. However, it takes a lot of effort to separate the filter bottle from the bottle cap when replacing the filter bottle with a screw lock.

Utility Model Content

Based on the above-mentioned deficiencies, the purpose of the present utility model is to provide a filter bottle of a water purifier, particularly an easily detachable filter bottle.

According to the above purpose, the utility model provides an easily removable filter bottle, comprising a bottle body and a bottle cap, a bottleneck of the bottle body having at least three limit blocks arranged at intervals and protruding from the surface of the bottleneck, and at least three limit structures correspondingly arranged on one side of the at least three limit blocks, and the inner surface of the bottle cap having a plurality of snap-fit blocks matching the contours of the at least three limit structures.

Each of the limiting structures is provided with a positioning portion, and each of the engaging blocks has a engaging portion matching the contour of the positioning portion.

The bottleneck and a body of the bottle are integrally formed or welded to each other.

A ring body is also provided which is sleeved on the outer surface of the bottle cap.

The ring body is a metal ring.

The bottle body and the bottle cover are made of metal or plastic material.

Each of the limiting blocks has a guiding portion and a stopping wall. The stopping wall extends downward from one end of the guiding portion. The guiding portion and the stopping wall together 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 providing a positioning part, and avoids the water hammer effect that causes the bottle body to loosen. By providing a limit block, the user can disassemble the bottle body and the bottle cap with less effort, thereby improving the convenience of use.

Detailed ways

In order to clearly illustrate the specific implementation method, structure and effect of the present invention, an embodiment is provided and described as follows with the accompanying drawings:

The descriptions of directions such as "front", "back", "upper" and "lower" involved in the present invention are only for the convenience of understanding. The present invention is not limited to these directions, but can be adjusted according to actual conditions. Please refer to Figures 1 to 2. The present invention provides an easily removable filter bottle, including a bottle body and a bottle cap 20. The bottle body has an accommodating space inside for accommodating a filter core. A bottleneck 15 of the bottle body extends upward from one end of a bottle body 12. The bottleneck 15 has three limiting blocks 16 arranged at intervals on the outer surface of the bottleneck 15, wherein the limiting blocks 16 protrude from the outer surface of the bottleneck 15, and each limiting block 16 has a guide portion 162 and a stop wall 161, and the stop wall 161 extends downward from one end of the guide portion 162. The guide portion 162 and the stop wall 161 together form a limiting structure 18 on the surface of the bottleneck 15, and each of the limiting structures 18 is provided with a positioning portion 17. The inner surface of the bottle cap 20 has a plurality of engaging blocks 21 that match the contours of the limiting structures 18. In other embodiments, the number of the limiting blocks 16 can be more than three, preferably four to five. The bottleneck 15 and the bottle body 12 of the bottle are integrally formed or welded to each other through ultrasonic welding or other techniques.

In the embodiment of the utility model, the guide portion 162 of the limit block 16 is further provided with a guide slope 162a at one end away from the stop wall 161. When the user wants to assemble the bottle cap 20 and the bottle body, the engaging block 21 of the bottle cap 20 is inserted into the limit structure 18 along the guide slope 162a until the engaging block 21 touches the stop wall 161 of the limit block 16, and then stops moving and completes the assembly of the bottle cap 20 and the bottle body.

It is further explained that each of the engaging blocks 21 has an engaging portion 211 that matches the profile of the positioning portion 17. In the embodiment of the utility model, the positioning portion 17 is a convex block, and the engaging portion 211 is a concave groove. In other embodiments, the engaging portion 211 may be a convex block, and the positioning portion 17 may be a concave groove, or the engaging portion 211 and the positioning portion 17 may be other concave-convex matching structures.

Since the flow of water has inertial momentum, the bottle cap 20 may become loose from the bottle body, thereby affecting the operation of the water purification system. The present invention increases the structural stability between the bottle cap 20 and the bottle body by providing a positioning portion 17, and prevents the bottle body from becoming loose due to the water hammer effect. By providing a stopper 16, the user can remove the bottle body and the bottle cap 20 with less effort, thereby improving the convenience of use.

In addition, the filter bottle of the present invention also has two sealing rings 19 sleeved on the end of the bottleneck 15 above the limit blocks 16, which can increase the structural stability between the bottle cap 20 and the bottle body and prevent water leakage.

To further illustrate, the bottle cap 20 and the bottle body may both be made of metal, or both be made of plastic, or the bottle cap 20 may be made of metal and the bottle body may be made of plastic, or the bottle cap 20 may be made of plastic and the bottle cap may be made of metal.

Please refer to FIG. 3 for a second embodiment of the present invention. In the second embodiment, a ring body 25 is sleeved on the outer surface of the bottle body. The ring body 25 is a metal ring. The ring body 25 can enhance the structural strength between the bottle cap 20 and the bottle body to prevent the bottle cap 20 from loosening from the bottle body.

The utility model provides a limiting block 16 to form a limiting structure 18 on the surface of the bottleneck 15 and provides a locking block 21 on the bottle cap 20, so that the user can separate the bottle body from the bottle cap 20 with less effort, thereby improving the convenience of operation. In addition, the positioning portion 17 is provided to increase the structural stability between the bottle cap 20 and the bottle body and avoid the occurrence of water hammer effect.
