Problems solved by technology

However, the existing water cups generally do not have anti-scalding function. People pour cold water or boiling water into the cup, but it is difficult for the user to judge the suitable temperature, or it is easy to accidentally drink it for a while, so that the tongue is scalded.
The anti-scalding cover on the water cup can only prevent scalding hands, and it is still difficult for users to judge the suitable drinking temperature of the water, and it is easy to burn the tongue when drinking

Embodiment 1

[0031] Such as Figures 1 to 3 As shown, an anti-scald water cup includes a cup body, an anti-scald cover is detachably fixed on the cup body, a water inlet and outlet are arranged in the middle of the anti-scald cover, and the water inlet and outlet include a channel extending downward from the anti-scald cover , a blocking part that can seal the passage is arranged below the passage, and the blocking part passes through a circular plate with a diameter slightly larger than the diameter of the lower port of the passage. The upper surface of the circular plate is horizontal and can fit the lower port of the passage. The lower end surface is fixedly connected to the support column, and the support column made of shape memory alloy is connected and fixed to the bottom of the cup body. The phase transition temperature of the shape memory alloy is the safe temperature of the water temperature and the support column elongates after the phase transition. The plugging part can be pus...

Embodiment 2

[0038] Such as Figure 4 with Figure 5As shown, the difference between this embodiment and Embodiment 1 is that the blocking member is an elastic air bag, and when the water temperature in the cup body is lower than the safe temperature, the radius of the elastic air bag is smaller than the inner diameter of the lower port of the channel. . The elastic airbag expands when heated and retracts when cooled. If the blocking part is set as an elastic airbag, then when hot water is discharged, the diameter of the elastic airbag is larger than the inner diameter of the channel due to the expansion of the elastic airbag, and the elongation of the support column pushes the airbag upwards, and the elastic airbag blocks the channel and cannot discharge water , and when the cold water comes out, the radius of the elastic airbag is smaller than the inner diameter of the channel, so that the water can be poured out through the channel, which prevents the user from using a water cup to po...

Abstract

The invention discloses an anti-scalding cup comprising a cup body; an anti-scalding lid is detachably fixed on the cup body; a water outlet / inlet is formed in the middle of the anti-scalding lid; thewater outlet / inlet comprises a channel downwards extending from the anti-scalding lid; a plugging part capable of plugging the channel is arranged below the channel; the plugging part is connected and fixed at the bottom of the cup body by a supporting column made of a shape memory alloy; the phase transition temperature of the shape memory alloy is a safe temperature of a water temperature, andthe supporting column is elongated after phase transition; and the plugging part can be jacked to plug the channel after the supporting column is elongated. When the water temperature in the cup is higher than the safe temperature, the supporting column can be subjected to phase-transition extension to jack the plugging part to plug the channel, and thus, hot water cannot be poured; and when the water temperature in the cup is lower than the safe temperature, the supporting column can be shortened to the original length due to a shape memory effect, the channel is not plugged by the plugging part, and water can be poured from the channel, so that the phenomenon that a user pours water with overhigh temperature to result in scalds is avoided.

Description

technical field [0001] The invention relates to the technical field of water cup equipment, more specifically, it relates to an anti-scalding water cup. Background technique [0002] Water cup is one of utensils that use the most general in people's daily life, and whether its comfort of use has very big influence to people. However, existing water cups generally do not have anti-scald functions. People pour cold water or boiling water into the cups, and it is difficult for users to judge the suitable temperature, or it is easy to drink by mistake for a while, so that the tongue is scalded. The anti-scalding cover on the water cup coat can only avoid scalding hands, and it is still difficult for users to judge the suitable drinking temperature of water, and it is easy to scald the tongue when drinking. Contents of the invention [0003] The purpose of the present invention is to provide an anti-scald water cup, which can prevent the tongue from being scalded by drinking w...
