Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water quality detection, in particular to a horn structure of an outdoor water quality detector. Background Technique
[0002] Water is the source of life. Humans cannot live without water in their daily life and production activities. The quality of domestic drinking water is closely related to human health. With the development of social economy, scientific progress and the improvement of people's living standards, people's requirements for the quality of domestic drinking water are constantly increasing, and the drinking water quality standards are also constantly developing and improving accordingly. Since the formulation of domestic drinking water quality standards is related to various factors such as people's living habits, culture, economic conditions, the level of scientific and technological development, water resources and their water quality status, there are differences in the requirements for drinking water quality not only between countries, but also between different regions of the same country.
[0003] Currently, when detecting water quality, a water quality detector is usually required. During the process of detecting the water source by the existing water quality detector, a horn needs to be installed to give an alarm prompt to people. When installing the horn, in order to prevent external water flow from splashing into the horn, a waterproof structure needs to be set around the horn. However, the setting of the waterproof structure will affect the sound quality played by the horn, resulting in a series of negative impacts. Content of the Utility Model

A backing plate is arranged between the inner walls of the top cover near the bottom edge. A horn body is arranged on the top of the backing plate near the front side edge. Blocks are fixed on both sides of the bottom of the horn body near the edges.
[0007] Optionally, the bottoms of the two blocks are respectively and correspondingly attached to the top of the backing plate. A plurality of kidney-shaped grooves are equidistantly arranged on the top of the backing plate near the front side edge.
[0008] Optionally, the front side of the backing plate is bent and extends upward into the interior of the top cover. The front side of the backing plate is attached to the inner wall of the front side of the top cover.
[0009] Optionally, the outer surface edge of the safety door is bent and extended backward, and the surface edge of the bent frame is bent and extended forward.
[0010] Optionally, the outer surface of the bent portion of the bent frame extends to the inside of the bent portion of the safety door, and a control panel is provided on the front side of the safety door.
[0011] Optionally, a base is fixed to the bottom of the protective housing, and an opening penetrating through the base is provided on the inner bottom surface of the protective housing.
