Description

Technical Field

[0001] The utility model relates to the field of duct machine detection, in particular to a device for lifting a liquid level switch in an duct water pump. Background Art

[0002] The duct unit is a new type of air conditioner, which solves the problem of wall-mounted units and cabinet units being exposed to the outside and affecting the appearance. It has a high degree of comfort and the duct length is longer than that of ordinary household air conditioners. It is more flexible to install and is loved by more and more consumers. It has a good market prospect.

[0003] Duct machines can generally be divided into models with water pumps and models without water pumps. Among them, duct machines with water pumps (hereinafter referred to as duct pump internal machines) are all equipped with a liquid level switch to detect the amount of condensed water in the duct machine casing and to determine whether the water pump is needed to work. When the duct pump internal machine is actually installed and used, the liquid level switch is in a natural hanging state under normal working conditions. However, during production, due to factory production needs, the direction of the unit is opposite to the actual installation direction, resulting in the direction of the liquid level switch also being opposite to the direction under normal working conditions. Therefore, when conducting production tests on the duct pump internal machine, the inspector must use tools to lift the liquid level switch and simulate the natural hanging state of the liquid level switch in order to simulate the normal operating state of the unit in order to conduct unit testing. In the current production process, inspectors generally use disposable chopsticks to reach into the duct pump internal machine and lift the liquid level switch to assist in testing. This method has the following problems: (1) The liquid level switch is inside the duct water pump. The lower cover, air outlet frame, side panel, etc. will block the liquid level switch. There is no special tool to lift the liquid level switch. Using disposable chopsticks to lift the liquid level switch is complicated to operate, easy to get loose, and cannot fit well. As a result, during the test, it is easy to report a full water protection failure, resulting in test failure and the need for retesting. It is time-consuming and affects efficiency. (2) Disposable chopsticks are not compatible and have poor durability. They are easy to poke the float of the liquid level switch, posing a quality risk. Utility Model Content
