Description

Cold air device, cover plate and closestool Technical Field The utility model relates to the field of toilets, in particular to a cold air device, a cover plate and a toilet. Background Users often feel uncomfortable due to higher ambient temperatures when using the toilet in hot days, and the use experience is reduced. In some prior art, the toilet cover plate setting can be set to hollow structure and built-in air supply mechanism, can blow to the user when the user turns up the cover plate and uses the closestool to improve user's comfort level. However, since the environment of the toilet is still at a high temperature level, the temperature of the wind delivered to the user is also close to the ambient temperature, and a good cooling effect cannot be achieved. Disclosure of Invention The utility model provides a cold air device, a cover plate and a closestool, and aims to solve the technical problem that in the prior art, the air outlet temperature of an air supply mechanism on the cover plate of the closestool is high, and a good cooling effect cannot be achieved. To achieve the above object, an embodiment of a first aspect of the present utility model provides a cooling air device, including: The shell is sequentially provided with an air inlet, an air duct and an air outlet, air flow can flow out from the air outlet after entering the air duct from the air inlet, the shell further comprises at least one accommodating cavity, and heat transfer can occur between the accommodating cavity and the air duct; The air supply mechanism is used for sending air flow into the air duct; The cold storage piece is arranged in the accommodating cavity; And the refrigeration module can be connected with the cold storage part in a heat conduction way, and when the refrigeration module is started, the refrigeration module absorbs the heat of the cold storage part so that the temperature of the cold storage part is lower than the temperature of the air flow entering the air duct.
