Water cup assembly, cleaning assembly and range hood

Abstract

The invention discloses a water cup assembly, a cleaning assembly and a range hood. The water cup assembly comprises a water cup, an ejection rod and an elastic part, wherein the water cup is provided with a cavity, and the side wall of one side of the cavity is provided with a first communicating opening communicated with the cavity; the first end of the ejection rod penetrates through the first communicating opening to extend into the cavity to seal the first communicating opening; the elastic part frequently pushes a second end to move towards a direction far away from the water cup; and when the ejection rod is pushed into the water cup through external force, the cavity is communicated with the first communicating opening. According to the water cup assembly for the range hood, the second end of the ejection rod is frequently pushed to move towards the direction far away from the water cup by utilizing the elastic part, so that the first end of the ejection rod seals the first communicating opening; when the second end of the ejection rod is pushed to move into the water cup through the external force, the cavity is communicated with the first communicating opening. Thus, the self sealing of the water cup can be realized, and the persistence and reliability of the sealing effect of the water cup assembly are enhanced.

Description

technical field [0001] The present invention relates to the technical field of household appliances, in particular to a water cup assembly, a cleaning assembly and a range hood. Background technique [0002] At present, there are mainly two working methods of household range hoods on the market: top suction type and side suction type. The effect is good, showing a clean and tidy atmosphere. The side-suction range hood is also called the near range hood. Because its installation position is closer to the stove, it can suck and exhaust the lampblack during the rising process of the lampblack. Therefore, it has certain advantages in the separation effect of the lampblack, and the space after installation is not obvious. Depressed, there is no risk of meeting. [0003] Regardless of the top-suction type or the side-suction type of the existing range hood cleaning system, most of them rely on the tight fit between the pipeline and the water cup outlet to realize the waterway se...

AI Technical Summary

Problems solved by technology

Due to the connection between the outlet of the cleaning water cup and the pipeline of the existing range hood, a high contact pressure is required to ensure the sealing effect, and the angle and insertion force of the water cup each time are different, which will lead to serious wear and deformation of the contact surface, so it cannot be guaranteed. good seal

Moreover, the deformation of the cup also has a great influence on the fit of the contact surface.
