Abstract: The present application provides an integrated oral care apparatus, including: an uneven housing, a composite member, a medium supply unit, a vector generation unit and a medium delivery member, where the uneven housing has a main extension line and oppositely arranged first end and second end, the main extension line extends from the first end of the uneven housing to the second end of the uneven housing, the vector generation unit connects with the composite member through a vector transmission rod, the vector transmission rod has a medium conveying channel, and the first end of the medium conveying channel is communicated with the composite member; the medium delivery member is configured to bridge between the vector generation unit and the medium supply unit, and has a communication channel, and the communication channel is hermetically coupled between the second end of the medium conveying channel and the medium supply unit.

Abstract: The present disclosure relates to the field of blowing equipment, more particularly, to a handheld hair drying apparatus which includes a handle, a main body and a controller. The handle includes a fluid inlet. The main body includes a housing, a tube body and a first end cover; the housing is connected to the handle; the tube body passes through the housing coaxially and is connected to the housing; the tube body has a first opening and a second opening opposite to each other, the first end cover enclosing the first opening; a first fluid outlet is formed between an end of the tube body where the second opening is located, the first fluid outlet communicating with the fluid inlet to form a first fluid channel; and the controller is arranged inside the tube body.

Abstract: An over-temperature protection structure and a hair drying apparatus is provided. The over-temperature protection structure includes a main body, a heater and an over-temperature protector; the heater includes an inner layer and a heating element, the inner layer being arranged on an inner side of the heating element and configured to support the heating element. Therefore, when the temperature of the heater is relatively high, the heater and the power source will be disconnected and the heater will cease to work, avoiding damaging the heater and surrounding elements because of overheat, thereby protecting the whole hair drying apparatus.
