Oral Irrigator Cleaning Brush with Finger Insertion and Nozzle Array
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oral cleaning devices for pets, infants, patients, and disabled persons are ineffective in thoroughly removing oral cavity waste, tartar, and bad breath, and often cause discomfort due to the design of the nozzle, which fails to provide precise cleaning and stimulation of teeth and gums.
Innovation Solution
A cleaning brush attached to an oral cleaner that feeds a cleaning solution at a predetermined water pressure, featuring a finger insertion space with nozzles and a backflow prevention mechanism, allowing for targeted and comfortable cleaning by inserting a finger into the brush.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a common nozzle is used to spray cleanser in the oral cavity, then the device structure is simple, but the cleaning precision and ability to stimulate teeth and gums is insufficient
Solution Approach 1:
The single common nozzle is divided into multiple nozzles arranged in an array. Each nozzle targets specific areas of teeth and gums, enabling precise cleaning and stimulation. The nozzle array includes multiple spray outlets positioned to reach different surfaces of teeth and gingival areas simultaneously.
Solution Approach 2:
Different regions of the nozzle array are designed with specific spray directions and angles to target different oral areas. The nozzle configuration provides localized cleaning action on teeth surfaces, gum lines, and interdental areas, with each nozzle optimized for its specific target zone.
2Reliability
If the nozzle directly contacts teeth during cleaning, then cleaning effectiveness is improved, but the pet becomes irritated or surprised causing discomfort
Solution Approach 1:
A protective cover made of elastic material is introduced as an intermediary between the nozzle array and the pet's oral tissues. The cover protects the pet from direct contact with the nozzle while allowing the spray to pass through, eliminating irritation and surprise reactions during cleaning.
Solution Approach 2:
The protective cover is constructed from elastic material that can deform and conform to the oral cavity shape. This flexible shell allows the nozzle array to maintain its cleaning function while the soft material prevents discomfort to the pet during the cleaning process.
3Reliability
If an abrasive toothpaste is used for animals, then some plaque can be removed, but the animal dislikes the taste and cannot continuously use it
Solution Approach 1:
The invention replaces abrasive toothpaste with a high-pressure liquid spray system. The cleanser is delivered through the nozzle array at sufficient pressure to mechanically remove plaque and tartar without requiring abrasive chemicals. This hydraulic approach eliminates taste objections while maintaining effective plaque removal.
Solution Approach 2:
The mechanical action of abrasive particles in toothpaste is replaced by the mechanical force of high-pressure liquid spray. The kinetic energy of the sprayed cleanser provides the cleaning action previously achieved through chemical abrasion, eliminating the need for flavors and making continuous use acceptable.
4Length of moving object
If a long nozzle stand is used to spray cleanser, then the device can reach the oral cavity, but the cleaning inside the oral cavity is not perfect
Solution Approach 1:
The single long nozzle is segmented into multiple nozzles of appropriate length, arranged in an array that spans the oral cavity. This segmentation allows each nozzle to target specific areas effectively while collectively providing comprehensive coverage that a single long nozzle cannot achieve.
Solution Approach 2:
The cleaning approach transitions from a single-point spray (one-dimensional) to a distributed array of spray points (two-dimensional or three-dimensional coverage). The nozzle array configuration provides multi-directional cleaning coverage, enabling thorough cleaning inside the oral cavity while maintaining appropriate nozzle length.

AI summary
A cleaning brush is attached to an oral irrigator that includes a supply pipe stored in a body unit, which has a control unit on the lower side of a cleaning tank in which a cleaning solution is stored, such that cleaning is carried out by supplying the cleaning solution at a predetermined water pressure. The cleaning brush includes a supply hole to which the supply pipe is connected and which is provided on the upper side of a finger cover having an insertion space into which a finger is inserted. Nozzles are formed at predetermined intervals on the upper side of a nozzle unit to which the supply hole is connected. A brush protrudes from the peripheral upper side at which the nozzles are formed. The supply hole has a connection member protruding outward and has a connector having connector-connecting pipes formed on both sides thereof.
