Abstract
Description
Technical Field
[0001] The utility model relates to the technical field related to water dispensers, and in particular to a three-in-one water inlet structure. Background Art
[0002] A water dispenser is a device that heats or cools water supplied from a water tank or a pure water barrel to facilitate drinking. A water tank or a pure water barrel is placed above the machine.
[0003] A water dispenser generally includes a casing, the top of which has a groove, and a smart core is fixedly arranged at the bottom of the inner side. The smart core has a water passage. When the water tank is placed on the top of the casing, the smart core pushes against the water stop valve on the water tank and moves upward, and the water in the water tank can flow out into the water passage to achieve water supply. When the pure water bucket is inverted and placed on the smart core and moves downward, the smart core pierces the sealing film at the mouth of the pure water bucket, and the water in the pure water bucket flows out into the water passage to achieve water supply. Although a water dispenser with this structure can meet certain usage requirements, when the sealing film at the mouth of the pure water bucket is torn off, or when there is no sealing film at the mouth of the pure water bucket, when it is inverted and placed on the casing, the pure water flows out and cannot be placed normally on the casing. Utility Model Content
[0004] In order to overcome the existing technical defects and solve the technical problem that the pure water bucket cannot be placed normally on the casing when the sealing film of the water outlet is torn off or there is no sealing film, the purpose of the utility model is to provide a three-in-one water inlet structure to solve the above technical problems.
[0005] The technical solution adopted by the utility model to solve the technical problem is as follows:
[0006] According to one aspect of the utility model, a three-in-one water inlet structure is designed, including: a casing, a bellows telescopic tube and a smart core seat, the casing is provided with a groove, the bottom of the groove is provided with a receiving groove, the bottom of the receiving groove is provided with a connecting part and a water outlet channel, the lower end of the bellows telescopic tube is connected to the connecting part, and the upper end is connected to the smart core seat, the inner side wall of the smart core seat is provided with an internal thread for cooperating with the external thread on the pure water bucket, the smart core seat is provided with a smart core inside, the smart core is provided with a penetrating water passage, the water outlet channel, the inside of the bellows telescopic tube and the water passage are connected, when the bellows telescopic tube is not stretched, it is placed in the receiving groove, when stretched, the smart core seat can be moved outside the groove, and can bend and flip with the bellows telescopic tube, and the bending and flipping angle is not less than 135°.
[0007] With the above technical solution, when the sealing film of the water outlet of the pure water bucket is torn off or there is no sealing film and it needs to be placed on the housing of the water dispenser, pull the smart core seat upward to stretch the bellows, and the bellows can be bent and flipped 180° after stretching, so that the upper part of the smart core seat is flipped 180° downward. When the smart core seat is flipped, the external thread at the mouth of the pure water bucket is connected with the internal thread on the inner wall of the smart core seat. After the connection is completed, flip the pure water bucket upside down and retract the bellows, so that the pure water bucket can be placed on the housing for normal installation, thereby solving the technical problem that the existing pure water bucket cannot be placed on the housing normally after the sealing film of the mouth of the bucket is torn off or there is no sealing film. Of course, when the stretching, bending and flipping angle of the bellows is not 180°, the pure water bucket needs to be placed in an inclined state to correspond to the smart core seat before it can cooperate with the thread of the smart core seat.
[0008] In order to better solve the above technical defects, the utility model also has a better technical solution:
[0009] In some embodiments, an annular buckle body is provided at both ends of the corrugated expansion tube, and the annular buckle body at the upper end of the corrugated expansion tube is buckled with the first annular groove on the outer wall of the smart core seat. The connecting part is a circular ring structure, and the annular buckle body at the lower end of the corrugated expansion tube is buckled with the second annular groove on the outer wall of the connecting part.
[0010] In some embodiments, a conical slope is provided on the upper end of the smart core.
[0011] In some embodiments, the smart core has symmetrically arranged rectangular notches on the top.
[0012] In some embodiments, the smart core is cylindrical, and its diameter gradually decreases from top to bottom and then gradually increases. Therefore, when the water supply pipe is connected to the smart core to supply water, the water supply pipe is not easy to fall off.
[0013] In some embodiments, the outer side wall of the smart core seat has external threads, so that the smart core can be connected to a water supply pipe with internal threads. BRIEF DESCRIPTION OF THE DRAWINGS
