Glue Gun Nozzle Adapter With Replaceable Sealing Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wide-width adapters of glue applicators require frequent cleaning due to residual solidified high-viscosity glue, leading to poor sealing and reduced lifespan, and are difficult to disassemble and maintain due to metal integrated joints.
Innovation Solution
An adapter with a sealing ring and stepped design, along with a polygonal shape and anti-slip surface, facilitates easy assembly and disassembly, improves sealing performance, and reduces maintenance frequency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If stainless steel adapters are used, then structural strength is improved, but sealing performance deteriorates due to residual solidified glue
Solution Approach 1:
The adapter is divided into a body portion and a separate sealing ring component. The sealing ring can be independently removed and replaced, allowing the sealing function to be maintained without replacing the entire adapter structure. This resolves the contradiction by preserving the strong stainless steel body while enabling easy renewal of the sealing element that degrades due to glue exposure.
Solution Approach 2:
The sealing ring is designed as a consumable component that can be easily replaced when degraded by glue exposure. Instead of replacing the entire expensive stainless steel adapter, only the relatively inexpensive sealing ring needs periodic replacement, maintaining sealing performance while reducing overall maintenance costs.
2Strength
If metal integrated joints are used, then connection strength is improved, but ease of operation deteriorates during disassembly and assembly
Solution Approach 1:
The adapter separates the joint connection function into distinct components: the threaded connection portions for strong attachment and the removable sealing ring for easy maintenance. This allows the joint to maintain strength during operation while enabling simple disassembly and reassembly by removing only the sealing ring component.
Solution Approach 2:
The adapter design allows the sealing ring to be dynamically removed and reinstalled, transforming the joint from a permanently fixed metal-integrated connection to a maintainable connection. The threaded portions provide stable connection during use, while the removable sealing ring enables easy operation during maintenance cycles.
3Duration of action of stationary object
If stainless steel adapters are used, then durability is improved, but maintenance frequency increases due to cleaning requirements
Solution Approach 1:
By separating the adapter into a durable stainless steel body and a removable sealing ring, the design allows the main body to remain in service for extended periods while only the sealing ring requires periodic replacement. This segmentation reduces overall maintenance frequency compared to replacing entire stainless steel adapters.
Solution Approach 2:
The sealing ring is designed as a replaceable component that can be discarded when degraded and replaced with a new one, while the valuable stainless steel adapter body is retained and reused. This extends the overall system lifespan and reduces maintenance frequency of the complete adapter assembly.

AI summary
The present application provides an adapter, a pipe assembly, a glue gun head and a glue applying device. The adapter is configured to connect a first pipe member to a second pipe member, wherein the adapter includes: a pipe joint, having a first accommodating part and a second accommodating part which are disposed at an interval in a first direction, the first accommodating part being configured to connect with the first pipe member, and the second accommodating part being configured to connect with the second pipe member; and a first sealing ring, disposed between the first accommodating part and the second accommodating part, so that the first pipe member and the second pipe member are able to abut against the first sealing ring from both sides of the first sealing ring in the first direction.
