Drainage device of air handling unit

Abstract

The utility model discloses an air handling unit drainage device, which relates to the technical field of vehicles and comprises a drainage pipe, an inner cavity of the drainage pipe is fixedly connected with a limiting assembly, the inner wall of the limiting assembly is clamped with an installation assembly, and the outer wall of the lower part of the installation assembly is in threaded connection with the inner cavity of the drainage pipe. The outer wall of the upper portion of the mounting assembly is slidably connected with a drainage adjusting assembly, and the drainage adjusting assembly is located above the limiting assembly. According to the drainage device of the air conditioning cabinet, under the action of the spring, the empty shell ball body can move downwards to be opened when water flow exists above the empty shell ball body so as to drain water, and when the air conditioning cabinet does not work, the empty shell ball body can move upwards under the pushing of the spring so as to seal the inner cavity of the drainage pipe. Due to the fact that the spring and the fixed guide rod are not fixedly connected, when the spring loses elastic force, the empty shell ball body can still move upwards to be sealed under the buoyancy of accumulated water below, and therefore the accumulated water below is prevented from flowing backwards when water is not drained.

[0026] Firstly, by the action of installation assembly 2, drainage adjusting assembly 5 is fixed between sealing assembly 4 and limiting assembly 3, under the action of drainage adjusting assembly 5 and sealing assembly 4, the inner cavity of drain pipe 1 is sealed, so as to prevent external accumulated water from flowing back when air conditioner box is not working, when drainage is needed, under the impact of water flow, drainage adjusting assembly 5 can move downwards, at this time, water flow can flow downwards through the inner wall of sealing assembly 4, so as to be discharged through the inner cavity of lower installation assembly 2.

[0027] As shown in the figure, Figure 3 Installation assembly 2 includes fixed ring 21, the outer wall of fixed ring 21 is threadedly connected with the inner cavity of drain pipe 1, the upper surface of fixed ring 21 is fixedly connected with filter screen 22, the inner cavity of central part of filter screen 22 is fixedly connected with fixed guide rod 23;

[0028] By the action of fixed ring 21, filter screen 22 and hollow sphere 52 can be fixed in the inner cavity of drain pipe 1, so as to facilitate installation, use and disassembly and replacement, wherein under the action of filter screen 22, external insects and impurities cannot enter the inside of drain pipe 1, so as to ensure smooth drainage.

[0029] Sealing assembly 4 includes sealing ring 41, the outer wall of sealing ring 41 is fixedly connected with the inner cavity of drain pipe 1, the lower surface of sealing ring 41 is fixedly connected with sealing ring 42;

[0030] By the action of sealing ring 41, hollow sphere 52 can be limited, so as to be sealed between hollow sphere 52 and sealing ring 41 under the action of sealing ring 42, so as to prevent accumulated water from flowing back downwards when not draining.
