Description

Technical Field

[0001] This utility model relates to the field of dissolved oxygen detection in water, specifically a device for detecting dissolved oxygen in water. Background Technology

[0002] Dissolved oxygen in water refers to molecular oxygen dissolved in water, usually denoted as DO, and expressed in milligrams per liter of water. Dissolved oxygen is an important indicator of a water body's self-purification capacity and is closely related to factors such as the partial pressure of oxygen in the air, water temperature, and water quality. Under natural conditions, dissolved oxygen in water mainly comes from the dissolution of oxygen in the atmosphere and the photosynthesis of aquatic plants. To facilitate the detection of dissolved oxygen concentration in water, detection equipment is needed. The "Analyzer for Detecting Dissolved Oxygen in Water" disclosed in application number "CN202021542929.4" represents an increasingly mature technology. However, its limitation is that "when the analyzer is not in use, the detection head cannot be securely fixed in the placement slot; careless placement of the detection head can lead to accidental damage from impacts, making replacement difficult." The current design is complex and difficult to use, which also reduces the aesthetic appeal of the analyzer itself. The cumbersome and complicated operation increases the frequency of detector head damage, thus compromising the normal operation of the analyzer. However, the device also has the following drawbacks: While the analyzer itself, along with the display screen and operating buttons, does effectively detect dissolved oxygen, its fixed length limits its detection range in water. Therefore, it is necessary to provide a device that can expand the detection range and enhance versatility. Furthermore, the device is inconvenient to support and adjust in height during use, and prolonged handheld use increases labor intensity. Therefore, it is necessary to provide a device that is easier to support and adjust in height, reducing labor intensity. Utility Model Content
