Description

TECHNICAL FIELD

[0001] The utility model relates to the field technology of face steamer, especially a cold and hot type face steamer. BACKGROUND

[0002] In the prior art, such as a cold and hot mixed type humidifying face steamer disclosed by Chinese patent CN208243771U, a cold humidifying mist outlet chamber is arranged below the water tank assembly, the cold humidifying mist outlet chamber is connected with a hot humidifying spray chamber through a water pipe, an atomizer is arranged at the bottom of the cold humidifying mist outlet chamber, and the hot humidifying spray chamber is provided with a heating body. Since the hot humidifying spray chamber is connected with the cold humidifying mist outlet chamber through the water pipe, the bottom of the hot humidifying spray chamber is lower than the bottom of the cold humidifying mist outlet chamber. After being used for a certain period of time, the cold humidifying mist outlet chamber will have no water available. The cold and hot exchange cannot be well realized. Moreover, the atomizer is arranged at the bottom of the cold humidifying mist outlet chamber, and the atomization effect is poor.

[0003] For example, a cold and hot spray face steamer disclosed by Chinese patent CN211050190U includes a cold mist generating device, which comprises a water-absorbing fiber cotton stick, a cold spray atomizer, and a water-absorbing fiber cotton stick guide column. One end of the water-absorbing fiber cotton stick extends into the lower part of the water tank along the water-absorbing fiber cotton stick guide column. In this structure, the water-absorbing fiber cotton stick guide column is suspended and is easy to shake and produce abnormal noise during the operation of the face steamer, which affects the user experience. Moreover, after being used for a certain period of time, the water-absorbing fiber cotton stick will have no water available. The water tank is directly filled through the water inlet, which is an internal water tank. It is difficult to observe the water amount in the cold and hot spray face steamer. The water amount is uncontrollable. When water needs to be added, the entire cold and hot spray face steamer needs to be carried for water filling, which is inconvenient for use.

[0004] Therefore, it is necessary to design a new technical solution to solve the above problems. UTILITY MODEL CONTENTS
