Description

An anti-residue water purifier spout

technical field

The utility model relates to the technical field of water purifiers, in particular to an anti-residue water outlet nozzle of the water purifier.

Background technique

The water outlet of the water purifier is installed at the water outlet position of the water purifier. Generally speaking, the water outlet flow channel of the water outlet is set in a straight cylinder shape. In many cases, when the water purifier stops water outlet, there are still some in the water flow channel of the water outlet. Some water droplets, due to the relatively large diameter of the water outlet of the water outlet, the surface tension formed between the water droplet and the hole wall is not enough to overcome the gravity of the water droplet itself. When the water cup is taken away, it will continue to flow out of the water outlet, forming the so-called residual water. Phenomenon.

Utility model content

The utility model aims to provide a water purifier spout that prevents residual water to solve the above problems in order to solve the problem that there is residual water in the spout of the current water purifier.

In order to achieve the above object, the utility model adopts the following technical solutions:

An anti-residue water purifier spout, the spout includes a water inlet at the upper end and a water outlet at the lower end, an installation hole is set outside the upper end of the spout; the middle of the spout is provided with a water inlet and an outlet The water flow channel of the water outlet, the upper part of the water flow channel is set as a gradient pipe with a gradually changing diameter, and the lower part of the water flow channel is set as a straight tube.

Preferably, the gradient pipe gradually becomes smaller or larger from top to bottom.

The beneficial effects of the utility model are: a water purifier spout for preventing residue of the utility model, the spout includes a water inlet at the upper end and a water outlet at the lower end, and an installation hole is arranged on the outer side of the upper end of the spout The middle part of the water outlet is provided with a water flow channel connecting the water inlet and the water outlet, the upper part of the water flow channel is set as a gradient pipe with a gradually changing caliber, and the lower part of the water flow channel is provided with a straight tube; through the combination of the gradient tube and the straight tube , the appropriate water inlet, water outlet aperture ratio and the size of the aperture itself, at the moment of stopping the water outlet, the volume of the residual water droplet in the hole is appropriate, and the surface tension generated between the water droplet and the hole wall is enough to overcome the gravity of the water droplet itself, thus inhibiting the flow of water droplets Flow out from the outlet.

Detailed ways

Below in conjunction with accompanying drawing 1,2 the utility model is further elaborated:

An anti-residue water purifier spout, the spout includes a water inlet 1 at the upper end and a water outlet 2 at the lower end, an installation hole 3 is provided outside the upper end of the spout; the middle of the spout is provided to connect the water inlet 1 and the water outlet 2 The water flow channel 4, the upper part of the water flow channel 4 is set as a gradient pipe 41 with a gradually changing caliber, the lower part of the water flow channel 4 is provided with a straight tube 42, and the straight tube 42 is shorter than the length of the entire water flow channel 4. 1/8 to 1/5.

The gradient pipe 41 gradually becomes smaller (as shown in FIG. 1 ) or gradually becomes larger (as shown in FIG. 2 ) from top to bottom.

An anti-residue water purifier spout of the utility model; through the combination of the gradual change pipeline 41 and the straight tube 42, the appropriate ratio of the apertures of the water inlet 1 and the water outlet 2 to the size of the aperture itself can be used when the water is stopped. In an instant, the volume of the remaining water droplet in the hole is appropriate, and the surface tension generated between the water droplet and the hole wall is sufficient to overcome the gravity of the water droplet itself.

The embodiments described above are only preferred examples of the utility model, and are not intended to limit the scope of implementation of the utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the patent scope of the utility model, All should be included in the utility model patent application scope.
