Water pump and humidifier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing humidifiers with spray-type wet water curtains face issues of water pump blockage due to scale or foreign matter accumulation, leading to the water pump not rotating.
Innovation Solution
A water pump design featuring a stator assembly, rotor assembly, and an end cap with a hooking structure that allows for easy removal of the impeller for cleaning, utilizing a hooking structure that hangs below the end cap to detach the impeller from the accommodating cavity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the water pump operates continuously to pump water to the wet curtain, then the humidification function is achieved, but scale and foreign matter accumulate causing the water pump to become blocked and not rotate
Solution Approach 1:
The water pump is divided into separable components: the end cap can be detached from the main body, and the impeller can be removed independently through the hooking structure. This segmentation allows easy access to cleaning without disassembling the entire pump, addressing the blockage issue while maintaining operational reliability.
Solution Approach 2:
The impeller is extracted as a separate removable component through the hooking structure design. By taking out the impeller independently, users can clean scale and foreign matter accumulation without affecting other pump components, resolving the blockage problem while preserving the pump's reliable operation.
2Stability of the object's composition
If the impeller is designed to be securely fixed in the accommodating cavity, then the water pump operates stably, but the impeller becomes difficult to remove for cleaning
Solution Approach 1:
The hooking structure provides a dynamic fixation system that adapts to different operational states: during normal operation, the impeller is securely held; during maintenance, the impeller can be easily removed by actuating the hooking structure. This dynamic design resolves the contradiction between stable fixation and easy removal.
Solution Approach 2:
The hooking structure acts as an intermediary mechanism between the end cap and impeller. It provides secure fixation during operation but allows easy release when needed, mediating between the conflicting requirements of stability and ease of operation through a simple mechanical interface.
3Device complexity
If the end cap is designed to completely seal the rotor assembly and impeller, then the pump structure is compact and sealed, but the impeller cannot be accessed for cleaning
Solution Approach 1:
The end cap is designed as a separable component that can be detached from the main pump body. This segmentation maintains the compact sealed structure during operation but allows easy access to the impeller for cleaning by removing the end cap, resolving the contradiction between structural compactness and cleaning accessibility.
Solution Approach 2:
The hooking structure is preliminarily designed to enable impeller removal before cleaning is needed. This preliminary action feature allows users to quickly remove and clean the impeller without complex disassembly, maintaining both structural compactness and ease of maintenance.

AI summary
The present invention, relating to the field of water pumps, discloses a water pump and a humidifier, which includes a stator assembly, a rotor assembly, and an end cap; the rotor assembly is connected with an impeller; the end cap at least covers and seals the rotor assembly and the impeller within an accommodating cavity; a side of the end cap facing the impeller is provided with a hooking structure; the hooking structure is configured to hang below the end cap when the impeller is assembled into the accommodating cavity or removed from the accommodating cavity; and after the impeller is assembled into the accommodating cavity, the hooking structure does not contact the impeller. The water pump and the humidifier of the present invention can allow for the impeller to be conveniently removed for cleaning, thereby quickly resolving the issue of the water pump being blocked and not rotating.
