Explosion-Proof Sealant Bottle for Tire Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing sealant bottles for tire repair using gas pressure can experience high pressure buildup due to blocked valve plugs or closed outlets, posing a risk of explosion during the tire repair process.
Innovation Solution
The sealant bottle incorporates an explosion-proof element with a rear and front housing, a tapered piston, and a spring mechanism, along with an air releasing hole and a lock washer, to automatically reduce pressure by allowing air to escape when it becomes too high, ensuring safety and preventing sealant leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If air pressure is used to press sealant into the tire, then the tire repair process becomes simple and efficient, but the pressure within the sealant bottle may build up excessively causing explosion danger
Solution Approach 1:
The explosion-proof element is pre-installed in the air inlet of the air throat before the tire repair process begins. This preliminary safety mechanism is already in place to prevent potential explosions by providing an automatic pressure relief pathway, allowing the system to operate efficiently without constant monitoring for pressure buildup.
Solution Approach 2:
The explosion-proof element acts as an intermediary safety device between the air compressor and the sealant bottle. It mediates the pressure transmission by allowing excess pressure to escape through the air releasing hole, thus protecting the sealant bottle from explosion while still enabling efficient sealant delivery during normal operation.
2Reliability
If the valve plug or sealant outlet becomes blocked during operation, then sealant delivery is interrupted, but pressure continues to build up causing safety hazards
Solution Approach 1:
The air releasing hole in the explosion-proof element extracts excess pressure from the system independently of the sealant delivery pathway. This separate pressure relief channel ensures that even if the sealant outlet is blocked, the pressure can still be released through the air releasing hole, preventing dangerous pressure buildup while maintaining reliable sealant delivery when needed.
3Loss of substance
If the sealant outlet is kept closed to prevent leakage, then sealant is preserved, but pressure cannot be released causing explosion risk
Solution Approach 1:
The system is segmented into two separate functional pathways: one for sealant delivery (through the sealant outlet) and another for pressure relief (through the air releasing hole in the explosion-proof element). This segmentation allows the sealant outlet to remain closed for preservation while the pressure relief pathway remains available to prevent explosion, solving the contradiction between sealant preservation and pressure management.
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 effectively reduces high pressure within the sealant bottle, preventing explosions and ensuring safety during tire repair while maintaining efficient sealant delivery to the tire, thus enhancing safety and convenience.
Implementation Method 1
a spring (74) is disposed within the front housing (72). One end of the spring (74) is placed in a cavity which is located inside the front housing (72) and is matched with the shape of the spring (74), while its other end is sleeved with an end cylinder (731) on the tapered piston (73)
Implementation Method 2
during the process of tire repair, the air can flow out through the air releasing hole on the explosion proof element so as to reduce the high pressure within the sealant bottle

AI summary
This invention discloses a sealant bottle for tire repair of gas pressure type which comprises a bottle body configured for containing sealant. The bottle body is provided with a sealant outlet and an air inlet, wherein a bottle cap is disposed at the sealant outlet and the air inlet is connected with a straight pipe assembly. An air-inlet end of the straight pipe assembly is connected with an air throat for transferring the air into the straight pipe assembly, and the air throat is further provided with an explosion proof element. A sealant guiding pipe disposed within the bottle cap is comprised of a first pipe section arranging along the axial direction of the bottle body and a second pipe section perpendicular to the first pipe section. A second step is disposed between inlets of the first pipe section and the second pipe section, and a rubber plug is further disposed between the inlet of the first pipe section and the second step. In this invention, when the pressure within the bottle body is too large, the explosion proof element on the air throat can be connected to the surrounding atmosphere which thus releases the air within the bottle body through the air releasing hole, lowers down the high pressure within the bottle body and ensures the safety usage for the sealant bottle. This invention is simple in structure and low in cost. Besides, it ensures the safety operation during the process of tire repair.
