Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] Such as figure 1 As shown, the present application mainly provides a water spray-proof structure, the suction nozzle is arranged at the cup mouth 51, and is tightly connected with the cup 5. The aperture at the upper end of the cup 5 gradually shrinks to the set size and then gradually expands to the original aperture size. The contracted position of the straw 1 is set as the constricted part 13, and the cross-sectional area size set by the constricted ...

Abstract

The invention mainly aims to provide a water spray preventing structure. The water spray preventing structure comprises a liquid storage jar, a cup lid and a straw, wherein a suction nozzle is arranged on a liquid storage jar opening; the straw, a water sucking channel and an air channel are arranged on the suction nozzle; aperture of the part, extending out of the upper end of the liquid storagejar, of the straw is gradually reduced to set size and then gradually increased to the original aperture size, and the shrinking position of the straw is set as a shrinking part; the straw penetratesthrough the water sucking channel; aperture of the air channel is larger than that of the shrinking part, the air channel is used for communicating an inner cavity of the liquid storage jar with an external environment, the total amount of high-pressure hot air discharged from the air channel is higher than that of air or hot water discharged from a suction nozzle hole, so that high-pressure air in the liquid storage jar can be discharged from the suction nozzle hole, and the probability of discharging hot water from the suction nozzle hole is reduced.

Description

technical field [0001] The invention relates to the technical field of daily necessities, in particular to a spray-proof structure. Background technique [0002] At present, there are also anti-spray suction nozzles or water cups for infants on the existing market. The anti-spray suction nozzles or water cups include liquid storage tanks, suction pipes, and cup covers. The aperture size is also the same and does not change. After the cup is covered, the high-pressure gas is trapped in the cup, and no pressure relief operation is performed on the high-pressure gas in the cup. When the temperature of the air in the cup is lower than the temperature of the hot water in the cup, after shaking or after a certain period of time , the air in the cup is heated and expands. At the moment of opening the lid, the water in the cup will be squeezed by the heated air and ejected from the nozzle quickly. Therefore, when the baby bites the nozzle to absorb water, the heat Water can still ...
