Specific implementation mode

[0019] A lifting device for the water outlet joint of a water dispenser. This product is mainly applicable to the use of a purified water dispenser installed in an embedded manner in a household cabinet. The water outlet joint lifting device of this product belongs to the local device protection of the water dispenser body, including the front casing 1 of the water dispenser, the water outlet joint 2, and the lifting and adjusting device 3. The front of the front casing 1 is flat and vertical; a recessed water receiving container recess 11 is provided on the front side wall of the front casing 1. The water receiving container recess 11 is used to set the water outlet joint 2 and facilitate the placement of the water receiving container, without the need for the water outlet joint 2 to protrude outward, preventing the water outlet joint 2 from being collided and being more beautiful; the water receiving container recess 11 is square-shaped, with a relatively general and simple design; a flat base 12 for supporting the water receiving container is provided at the bottom of the water receiving container recess 11, which is used to place and support water receiving containers such as a water receiving kettle, a water receiving cup, a water receiving basin, and a water receiving tray; the water outlet hole of the water outlet joint 2 is opened at the front bottom, and the water outlet hole is located above the flat base 12 for supporting the water receiving container. The water receiving container is located on the flat base 12 for supporting the water receiving container, and the water outlet hole is aligned with the container mouth for receiving water. The water outlet holes are: a hot water outlet hole 2B and / or a normal temperature water outlet hole 202. The water inlet hole of the water outlet joint 2 is opened at the rear wall, and the water inlet hole is used to connect the internal water pipeline of the water dispenser. The water inlet holes are: a hot water outlet hole 2B or a normal temperature water outlet hole 202 or a chilled water inlet hole 203, or a combination of the foregoing. After the water enters from the water inlet hole, it flows through the internal water channel and then flows out from the water outlet hole into the water receiving container. The main technical improvement of this product is that: a joint lifting and adjusting hole 13 is provided on the inner vertical wall of the water receiving container recess 11. The joint lifting and adjusting hole 13 is arranged vertically in a long strip shape. The water outlet joint 2 is movably installed in a through-hole manner at the joint lifting and adjusting hole 13. The water outlet hole and the front section of the water outlet joint 2 are arranged in the water receiving container recess 11 for docking and cooperating with the water receiving container to receive water; the rear wall of the front casing 1 is fixedly connected with a lifting and adjusting device 3 through a screw assembly. The lifting and adjusting device 3 is fixedly connected with the rear part of the water outlet joint 2 through a screw assembly. The water outlet joint 2 realizes the lifting height adjustment through the lifting and adjusting device 3; since the water receiving containers such as water receiving kettles, water receiving cups, water receiving basins, and water receiving trays at home have different heights and are not unified; the water outlet joint 2 of this product generally descends to a low position to be suitable for the heights of most water receiving containers, such as water receiving cups, water receiving basins, water receiving trays, etc., to prevent the water receiving space from being too high and prevent water from splashing out; when some water receiving kettles with high barrels, high-footed cups, etc. need to receive water, the height space between the water outlet joint 2 and the flat base 12 for supporting the water receiving container is not high enough to be normally located and vertically receive water. At this time, the water outlet joint 2 can be pushed upward by hand to raise it, so that the height space between the water outlet joint 2 and the flat base 12 for supporting the water receiving container becomes higher, so that the water receiving kettles with high barrels, high-footed cups, etc. can be normally located and fixed on the flat base 12 for supporting the water receiving container and vertically receive water, preventing or reducing water splashing and facilitating water receiving. This structure has strong practicability.
