Description

A quick-connect filter bottle

technical field

The utility model relates to a filter bottle, in particular to a special quick-connect filter bottle for a pure water machine.

Background technique

At present, most of the common filter bottles for pure water machines on the market are connected to the external water pipes in the traditional threaded connection form, and the water pipe is locked at the water pipe interface of the filter bottle by using the threaded connection structure. However, in the actual installation process of the external water pipe, it takes a lot of time to tighten it, and in the process of tightening the screw thread, it is easy to be screwed and stuck, the disassembly and assembly are troublesome and time-consuming, and the work efficiency is low. In addition, in the actual use process, the water pipe interface of the filter bottle is often prone to water leakage, and the sealing effect is poor, which directly affects the normal operation of the filter bottle and the water purifier. In the process, the process is complicated, and the accuracy of the processing process is not easy to control. Therefore, the connection structure of the special filter bottle water pipe for the existing pure water machine needs to be improved.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies of the prior art, and provide a quick-connected filter bottle with simple and fast disassembly and assembly operation of the water delivery pipe and good sealing performance.

The purpose of the invention of the utility model is achieved in the following way: a quick-connect filter bottle, including a bottle body and a water delivery pipe, the bottle body is provided with a water pipe interface matched with the water delivery pipe, and it is characterized in that: the water pipe interface is provided with The quick-connect end cap matched with the cavity of the nozzle is provided with a positioning card that can lock the water delivery pipe on the quick-connect end cap.

There is a slidable wedge-shaped connection between the quick-connect end cap and the positioning card.

The water pipe interface is provided with a sealing ring matching the water pipe.

The utility model improves the filter bottle in the prior art, and replaces the traditional thread locking method with the wedge-shaped interlocking structure of the positioning card and the quick-connect end cap. The user only needs to insert the water pipe directly into the hole of the water pipe interface of the filter bottle to be locked on the water pipe interface of the filter bottle, and the water pipe can be easily pulled out only by pushing the positioning card, realizing the connection between the water pipe and the filter bottle. The disassembly operation of the bottle is simple and fast, which improves the actual work efficiency; moreover, after the water delivery pipe is wedge-shaped locked by the positioning card and the quick-connect end cap, it is then sealed and connected with the water pipe interface through the sealing ring, and the sealing effect of the product is good.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

According to Fig. 1 and Fig. 2, the quick-connect type filter bottle of the present utility model comprises a bottle body 1, and a water pipe interface 3 matched with a water delivery pipe 2 is provided on the bottle body 1. The water pipe interface 3 described in the utility model is provided with a quick-connect end cover 4 matching the nozzle cavity, and the quick-connect end cover 4 is provided with a positioning card 5 that can lock the water delivery pipe 2, and the quick-connect end cover 4 and The slidable wedge-shaped connection between the positioning cards 5 is mainly realized by matching the wedge-shaped protrusions on the positioning cards 5 with the reverse slope of the quick-connect end cover 4 . At the same time, in order to strengthen the tightness between the water pipe 2 and the water pipe interface 3 of the bottle body 1 , a sealing ring 6 matched with the water pipe 2 is provided in the water pipe interface 3 . When installing the water delivery pipe 2, you only need to insert one end of the water delivery pipe 2 directly into the hole of the positioning card 5 to the bottom and tighten the sealing ring 6. During this period, the water delivery pipe 2 drives the quick-connect end cover 4 and the positioning card 5 to realize wedge-shaped interlocking , so that the water pipe 2 is firmly locked on the water pipe interface 3, so that the water pipe 2 will not slide relative to each other and can withstand the fluid pressure; when disconnecting, only need to press the outer end of the positioning card 5 to move inward for a while distance, the water delivery pipe 2 can be pulled out, which realizes the simple and fast disassembly operation of the water delivery pipe 2 and the bottle body 1, avoids the water leakage link, and has a good sealing effect.
