Dust-proof water dispenser

Abstract

The invention discloses a dust-proof water dispenser which comprises a water bucket, a bucket cover for covering a nozzle of the water bucket, a first pipe, a second pipe, a transparent pipe, an air tank, a check valve and a sucking pump; an air inlet channel which is communicated with an inner cavity of the water bucket and allows air to enter therein is formed between the bucket cover and the nozzle of the water bucket; a connection pipe is arranged on the outer top wall of the bucket cover in an upward extending mode; the first pipe is inserted into the water bucket and communicated with the second pipe; the second pipe is in cup joint fit with the connection pipe; the lower end of the transparent pipe is communicated with the connection segment of the second pipe, and the second pipe further comprises a water inlet segment and a water outlet segment, wherein the connection segment is arranged between the water inlet segment and the water outlet segment and is in cup joint fit with the water inlet segment and the water outlet segment; the water outlet segment is provided with a valve, and the valve is used for controlling switching-on and switching-off of the water outlet segment; the highest point of the transparent pipe is higher than the highest point of the water outlet segment; the transparent pipe is communicated with one of air openings of the air tank through an air pipe, and the other air opening of the air tank is communicated with the sucking pump through the check valve. By means of the dust-proof water dispenser, dust entering the water dispenser can be reduced, and accordingly contamination of drinking water is avoided.

Description

technical field [0001] The present invention relates to water dispensers. Background technique [0002] Existing water dispensers generally have a groove on the top of the water dispenser, a connecting pipe is installed in the groove, and a water inlet is provided on the connecting pipe, the opening of the groove is upward, the bucket is inverted in the groove and the connecting pipe is inserted into the water nozzle of the bucket After that, the water flows into the groove from the bucket by its own gravity. Since the groove is completely exposed to the external space, pollutants such as dust from the outside can easily enter, and then flow out with the water, polluting the drinking water. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a dust-proof water dispenser, which can better reduce dust and other pollutants from entering the water dispenser, thereby avoiding drinking wate...
