Cleaning head for a floor cleaning equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor cleaning equipment face issues with cumbersome operation and inefficiency in cleaning smooth floors, as they require frequent tool replacements and can lead to water leakage and equipment damage due to improper water management.
Innovation Solution
A cleaning head for floor cleaning equipment featuring a water supply tank with a venting hole, a communicating tube connecting two chambers, and a water distributor with an absorbent core, allowing for smoother water supply and efficient humidification of the mop cloth, preventing water overflow and maintaining cleanliness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a water tank with adjusting ports is used to control water output, then water supply can be adjusted, but water leaks from the open adjusting port and wets the exterior of the tank body
Solution Approach 1:
The patent introduces a one-way valve as an intermediary component between the water tank interior and the adjusting port. This one-way valve allows air to enter the tank through the adjusting port when needed for pressure equalization, but prevents water from leaking outward. The valve acts as a mediator that selectively permits airflow in one direction while blocking water flow in the opposite direction, thus resolving the contradiction between water supply control and water leakage prevention.
2Reliability
If the water tank is provided with a venting hole for air entry, then air can enter the tank, but water still comes out at both the open adjusting port and the liquid outlet
Solution Approach 1:
The one-way valve serves as a selective intermediary that distinguishes between air and water flow. It permits air to pass through the adjusting port to fulfill the venting function, while its structural design (such as a float or diaphragm mechanism) automatically blocks water from passing through the same port. This resolves the contradiction by enabling reliable air venting while preventing water leakage through the same opening.
Solution Approach 2:
The one-way valve introduces local quality differentiation at the adjusting port - it has different permeability properties for different substances (air versus water). The valve structure is designed with specific local characteristics (such as hydrophobic properties or pressure-dependent opening) that allow it to selectively permit air while blocking water, thus resolving the contradiction between venting function and leakage prevention.
3Ease of operation
If adjusting ports are located at the bottom of the water tank, then water output can be controlled, but water leaks from the open port and enters the inside of the floor sweeping robot
Solution Approach 1:
The one-way valve positioned at the bottom adjusting port acts as a protective intermediary that prevents water from entering the robot's interior. It allows air to pass through for pressure equalization during normal operation, but its design prevents water from passing through to protect sensitive electronic components and the motor from water damage, thus resolving the contradiction between water output control and equipment protection.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables a consistent and efficient water supply to the mop cloth, enhancing cleaning efficiency and preventing water leakage, thus improving the overall cleaning process and maintaining floor cleanliness.
Implementation Method 1
a communicating tube that puts the first chamber and the second chamber in communication, the communicating tube having a lower end opening in communication with the second chamber and an upper end opening extending into the first chamber and located in an upper portion of the first chamber
Implementation Method 2
The plurality of water outlet holes are provided on the lower cover. An absorbent core is provided at the water outlet, the absorbent core being partially exposed from the corresponding water outlet and being capable of guiding water flowing into the second chamber to the outside of the water distributor through the water outlet hole
Implementation Method 3
a water supply tank used for supplying water to the mop cloth, the water supply tank being mounted to the cleaning head body and located above the base plate, the water supply tank being provided with a venting hole that communicates with the exterior
