Description

Technical Field

[0001] The present invention relates to a bottle mouth connector, specifically a bottle mouth connector applied to an instant water dispenser. Background Art

[0002] At present, the bottle mouth connectors of instant water dispensers on the market only have a single thread and can only match water bottles of one caliber. If different caliber water bottles need to be matched, more than two sets of different bottle mouth connectors need to be configured at the same time. Some merchants also call it the same meaning as bottle caps with more than two different caliber threads.

[0003] Some bottle mouth connectors use a stepped shape, or a conical shape, or a combination of a step and a cone. The number of different bottle mouths connected by these bottle mouth connectors is small, and the threads are easily damaged when screwed in, and the appearance is not beautiful, which cannot meet the user's requirements. Therefore, further improvement is needed. Summary of the Invention

[0004] The purpose of the present invention is to provide a bottle mouth connector and an instant water dispenser thereof that can connect various bottle mouths, meet user requirements, are flexible and fast to install, effectively solve the problem of only a single thread for the bottle mouth connector of the instant water dispenser on the market, and are convenient for connecting water bottles of various different calibers, so as to overcome the deficiencies in the prior art.

One or more mutually spaced first threads are provided at the opening of the bottle mouth connector seat. A threaded sliding block is provided inside the bottle mouth connector seat. One or more mutually spaced second threads are provided on the threaded sliding block. An elastic member is provided between the inside of the bottle mouth connector seat and the threaded sliding block; wherein, when installing a water bottle with a bottle mouth diameter > the inner diameter of the threaded sliding block, the threaded sliding block slides along the inner wall of the bottle mouth connector seat and presses the elastic member, and at least part of the elastic member is compressed inside the bottle mouth connector seat; the first thread and / or the second thread cooperate with the bottle mouth; or, when installing a water bottle whose bottle mouth just matches the second thread, the elastic member is not compressed, so as to connect water bottles of various different calibers. Combining two or more sets of threads with different calibers on a set of bottle mouth connectors saves the need to configure multiple sets of bottle mouth connectors with only a single thread, which is simple and practical, saves costs, and also avoids the possibility of consumers losing due to improper storage of multiple sets of bottle mouth connector accessories.

[0006] The elastic member is a compression spring.

[0007] By having more than one set of threads with different diameters in the bottle mouth connector, each set of threads is evenly distributed in the bottle mouth connector in three sections. When matching with water bottles of different calibers, it will be automatically adapted. The threaded sliding block can be screwed into a water bottle with a smaller caliber. When the smaller caliber water bottle is screwed in, the water bottle only cooperates with the second thread of the threaded sliding block.
