Description

Technical Field

[0001] The utility model relates to the technical field of drinking water auxiliary equipment, in particular to a bottled water fresh-keeping device. Background Art

[0002] As people's living standards improve, they have higher requirements for water quality. When people use tea bar machines or drink Gongfu tea, they often need to pump water from a low-lying bottled water into the tea set through a water pump for heating. At present, the water inlet pipe of the corresponding water pump of the tea bar machine usually adopts a two-way pipe joint. In specific applications, one end of the two-way joint is inserted into the middle opening of the bottle cap of the bottled water. The water inlet pipe at the lower end of the two-way pipe is located in the bottled water. The other end of the two-way joint is connected to the water inlet pipe of the water pump through a pipeline. When working, the water pump generates negative pressure suction to pump water out through the water outlet into the tea set for heating.

[0003] Although the existing two-way joints meet the needs to a certain extent, due to structural limitations, there are still the following technical problems that need to be solved urgently. First, the two-way joint is made of hard plastic material and has no plasticity. It has a long application time and is affected by factors such as wear and tear, and there is a probability that the outer diameter will become smaller. Therefore, after one end of the two-way joint is inserted into the middle opening of the bottled water cover, the two ends cannot guarantee effective sealing. In addition, in order to ensure that there is no negative pressure in the barrel and the water pump cannot pump water normally, a ventilation groove is left at one end of the two-way joint to allow external air to enter the barrel. In this way, external dust and the like can easily enter the barrel and cause water pollution, which has an adverse effect on people's healthy drinking water. Second, the two sides of the two-way joint and the water inlet pipe are connected because of the lack of plasticity. When the inner diameter of the water inlet pipe increases due to long-term plugging and unplugging, or the outer diameter of the two sides of the two-way joint decreases due to wear and tear, the sealing of the water inlet pipe cannot be guaranteed, which leads to the inability of water to effectively enter the water pump. In summary, the above-mentioned shortcomings have resulted in the inability of existing bottled water to achieve a fresh-keeping effect. It is particularly necessary to provide a device that can effectively seal the bottle cap and water inlet pipe of the bottled water and prevent dust and the like from entering the barrel as much as possible. Summary of the invention

[0004] In order to overcome the drawbacks of existing bottled water connector equipment (fresh-keeping equipment) as described in the background due to structural limitations, the utility model provides a bottled water fresh-keeping device which can be conveniently connected to a water pump and a bottled water bottle cap, and can effectively seal the bottle cap socket, the water inlet of the water pump, and the water inlet pipe in the barrel, thereby ensuring that external air can enter the barrel and reducing the chance of dust and the like entering the barrel when not in use.

After the water inlet pipe is connected to the water inlet and the water outlet respectively, the outer diameter of the sealing gasket is slightly larger than the inner diameter of the water inlet pipe. The inner side of the sealing gasket can effectively seal and fit with the outer side of the water inlet and the water outlet through the expansion buckle effect. In this way, the sealing performance of the water inlet pipe and the water inlet and the water outlet is better; (2) The lower end of the ventilation groove of the present invention is located at the inner upper end of the lowermost sleeve position of the sealing ring and is sealed. Only when the water pump is pumping water will the external air flow break through the lowermost end of the sealing ring on the corresponding side and enter the water bucket. On the basis of preventing the generation of negative pressure in the bucket, it also reduces the probability of dust and the like entering the bucket when it is not in use, which can achieve a better hygienic effect.
