Electromagnetic Diaphragm Pump Gravity Drainage Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electromagnetic vibrating diaphragm pumps face issues with water ingress, leading to component deterioration, rusting, and difficult maintenance due to the inability to effectively drain water from internal chambers, and the addition of separate water-prevention components increases cost and complexity.
Innovation Solution
The design incorporates sloping communicating passages and chambers to facilitate gravity-driven drainage, eliminating the need for additional water-prevention components, with inclined bottom portions and concave drainage areas to efficiently direct water from the suction chamber to the exhaust port, ensuring water does not remain inside the pump.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional electromagnetic vibrating diaphragm pumps are used with centrally mounted valves and communicating passages, then the pump structure is simple and compact, but water remains inside the pump chambers causing component deterioration and rusting
Solution Approach 1:
The patent applies asymmetry by positioning the suction valve and exhaust valve at different locations on the partition wall, and by forming the communicating passages with asymmetric bottom portions that slope downward. Specifically, the bottom portion of the first communicating passage slopes downward toward the compression chamber side, while the bottom portion of the second communicating passage slopes downward toward the exhaust chamber side. This asymmetric configuration creates gravity-driven water drainage paths that prevent water accumulation without requiring additional components.
Solution Approach 2:
The patent creates equipotentiality for water drainage by designing the communicating passages with bottom portions that slope downward to form drainage paths. The first communicating passage has its bottom portion sloping downward toward the compression chamber, and the second communicating passage has its bottom portion sloping downward toward the exhaust chamber. This gravitational equipotential design allows water to naturally drain from higher to lower positions, ensuring complete water removal without additional energy input or components.
2Ease of repair
If conventional pumps are used without drainage structures, then the pump structure remains simple, but maintenance becomes very troublesome when water enters the pump
Solution Approach 1:
The patent implements self-service by incorporating drainage structures into the existing pump body that automatically drain water without requiring external intervention or disassembly. The first communicating passage with its downward-sloping bottom portion drains water from the suction chamber to the compression chamber, and the second communicating passage with its downward-sloping bottom portion drains water from the exhaust chamber to the exhaust port. This self-draining capability eliminates the need for manual water removal and frequent maintenance.
3Reliability
If a filter is added to prevent water inflow, then water prevention is improved, but the number of components increases resulting in higher cost and size
Solution Approach 1:
The patent converts the harmful effect of water ingress into a beneficial drainage function by designing the communicating passages with downward-sloping bottom portions. Instead of trying to prevent water entry with filters, the patent allows water to enter but then uses gravity to drain it through the asymmetrically configured passages. The first communicating passage drains water to the compression chamber, and the second communicating passage drains water to the exhaust port, transforming water from a harmful substance into a flowable element that is automatically removed.

Function Achieved in This Case
This solution prevents component deterioration and rusting by ensuring water is drained from the pump through the exhaust port, reducing maintenance needs and eliminating the requirement for additional water-prevention components, while maintaining pump performance.
Implementation Method 1
magnetic coil portions (2) connected to an alternating-current power source, an oscillator (4) being equipped with a permanent magnet (3) and being driven so as to make a reciprocating motion by applying an alternating voltage to the magnetic coil portions (2)
Implementation Method 2
a bottom portion inside the suction chamber (62) slopes down toward the first communicating passage (P1) such that the compression chamber side (61) thereof is lower than the suction chamber side (62), and a bottom portion of the first communicating passage (P1) slopes down such that its compression chamber side is made lower

AI summary
An object of the present invention is to provide an electromagnetic vibrating diaphragm pump with a draining structure which is a simple structure and can easily drain water having flowed into the pump without providing a separate member for preventing inflow of water. A first communicating passage P1 is formed at a bottom end of a partition wall W1 between a suction chamber 62 and a compression chamber 61, and a bottom portion 62a inside the suction chamber 62 slopes down toward the first communicating passage P1 such that the compression chamber 61 side thereof is lower than the suction chamber 62 side; a second communicating passage P2 is formed at a bottom end of a partition wall W2 between an exhaust chamber 63 and the compression chamber 61, and a bottom portion 61a inside the compression chamber 61 slopes down toward the second communicating passage such that the exhaust chamber 63 side thereof is lower than the compression chamber 61 side; and a bottom portion inside the exhaust chamber 63 slopes down toward the exhaust port such that the exhaust port side is made lower, and the exhaust port slopes down such that an outlet side thereof is made lower.
