Description

TECHNICAL FIELD The utility relates to the technical field of toilet manufacturing, and in particular to a drying device. BACKGROUND A toilet is one of the indispensable sanitary wares in modern society. With the development of the toilet manufacturing industry, people have higher and higher requirements for the integration and functionality of the toilet, and the use of the toilet is becoming more and more intelligent. For hygiene reasons, the existing smart toilets generally have cleaning functions, such as cleaning the hips of users after going to the toilet, and cleaning the ceramic parts of the toilet. In addition to the cleaning functions, the existing smart toilets usually have a warm air drying function, and the users do not need to wipe their hips with paper after going to the toilet, so that the toileting experience is better. However, the structures of the existing smart toilets still need to be improved. SUMMARY The problem to be solved by the utility is to provide a drying device, a fixed seat assembly and a toilet, in order to reduce the risk of water or dirt entering an air outlet, thus being helpful in protecting a heater. In order to solve the above problem, the utility provides a drying device, including a housing, provided with an air inlet and an air outlet; a fan, positioned inside the housing and adjacent to the air inlet; a heater, located inside the housing and adjacent to the air outlet; and an air bucket, disposed at the air outlet. Optionally, the air bucket includes a first air duct and a second air duct connected with each other, and the first air duct forms an included angle with the second air duct. Optionally, the first air duct and the second air duct are smoothly connected with each other by means of rounded corners. Optionally, the top end of the first air duct is connected with the air outlet, one end of the second air duct is connected with the bottom end of the first air duct, and the other end of the second air duct extends in the direction away from the housing. Optionally, the included angle between the first air duct and the second air duct is 87°-101°. Optionally, the included angle between the first air duct and the second air duct is 93°, and the first air duct supplies air in the vertical direction. Optionally, the length ratio of the first air duct to the second air duct is 2:1. Optionally, the housing includes an upper housing and a lower upper housing, and the upper housing is detachably connected with the lower housing. Optionally, the drying device further includes a thermistor, positioned in the air bucket. Accordingly, the utility also provides a fixed seat assembly, including the drying device and a fixed seat, the housing is disposed on the fixed seat, and the air bucket extends out of the bottom of the fixed seat. Accordingly, the utility also provides a toilet, including the fixed seat assembly and a toilet body provided with a toilet basin, the fixed seat assembly is disposed on the toilet body, and the air bucket is located at the top edge of the toilet basin. Compared with the prior art, due to the adoption of the technical solution, the utility has the advantages that: The drying device includes a housing, a fan, a heater, and an air bucket. The housing is provided with an air inlet and an air outlet. The fan is positioned inside the housing and adjacent to the air inlet, and the rotation of the fan causes air to rush into the air inlet to form air power. The heater is located inside the housing and adjacent to the air outlet, and is used for heating the passing air so as to enable the air outlet to output warm air. The air bucket is disposed at the air outlet, and the water or dirt sprayed to the air outlet is blocked by the air bucket and is therefore difficult to enter the air outlet. Accordingly, the air bucket is capable of reducing the risk of the water or dirt entering the air outlet, thus being helpful in protecting the heater.
