Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and in particular to a sealing structure for an emergency button on a power supply box and an air conditioner. Background Technology

[0002] Power supply units for electrical equipment such as air conditioners typically require a power box and a cover, which are usually connected and secured with screws. To prevent sudden power box malfunctions, a common feature is an emergency stop button, allowing users to shut down the power supply by pressing it. The power box has a direct-access button hole, through which the emergency stop button is inserted for easy operation. However, this open design allows external air to enter the power box through the gap between the emergency stop button and the button hole, resulting in poor sealing. Utility Model Content

[0003] Based on this, the purpose of this utility model is to overcome the shortcomings of the prior art and provide a power box emergency button sealing structure and an air conditioner. According to the embodiments of this utility model, the power box emergency button sealing structure and air conditioner can effectively improve the sealing performance of the button through hole by sealing the elastic sealing cylinder with the button through hole, thereby improving the sealing effect of the power box.

[0004] To achieve the above objectives, a first aspect of this utility model provides a sealing structure for an emergency button on a power supply box. A through-hole for the button is provided on the side wall of the power supply box. The emergency button is located inside the power supply box and on one side of the through-hole. The sealing structure is an elastic sealing cylinder, the shape of which is adapted to the shape of the through-hole. An annular groove is provided on the outer wall of the elastic sealing cylinder.

[0024] In related technologies, power supply units for electrical equipment such as air conditioners generally require a power supply box and a power supply box cover, which are typically connected and secured using screws. To prevent sudden power supply box malfunctions, a common power supply box includes an emergency stop button, allowing users to stop the power supply by pressing it. The power supply box has a direct button opening, through which the emergency stop button is inserted for easy pressing. However, this open structure allows external air to easily enter the power supply box through the gap between the emergency stop button and the button opening, resulting in poor sealing.

[0025] In view of this, the present utility model provides a sealing structure for the emergency button 11 of the power box and an air conditioner.
