Description

Electronic balance wind shield Technical Field The utility model relates to the technical field of auxiliary equipment of metering devices, in particular to a wind shield of an electronic balance. Background In the process of accurately weighing an electronic balance, a wind shield is usually arranged, a weighing area is isolated from the outside air by the wind shield, and the air flow in the environment is effectively blocked, so that the weighing accuracy and stability are improved. Moreover, the windshield can also protect the balance, prevent dust, sundries and the like from entering the balance, prevent the dust, the sundries and the like from falling on a sensor and a tray of the balance, and be favorable for ensuring the normal work of the electronic balance. The existing electronic balance windshield only plays a role in physically isolating a weighing area of the electronic balance, and does not have a dehumidifying and moisture absorbing function. When the ambient humidity is higher, can't carry out effective processing to the moisture in the cover, be in high humidity environment for a long time under, electronic balance's part is easy to wet rust, and the circuit also can receive the influence, leads to weighing inaccuracy. Especially under the condition that the windshield is not sealed well, moist air in the external environment can enter the windshield through a gap between the cover body and the electronic balance, and then water vapor is condensed in the windshield, so that the weighing accuracy of the electronic balance is affected. Disclosure of Invention The utility model aims to provide a windshield structure for facilitating the placement of a drying medium in a windshield in the use process of an electronic balance, reducing the humidity in the windshield and avoiding the influence of the environmental humidity on the weighing accuracy of the electronic balance. In order to achieve the above object, the present utility model provides an electronic balance windshield, comprising a cover body, wherein the cover body is arranged above an electronic balance, is used for covering a weighing area of the electronic balance, forms a closed cavity above the electronic balance, and is internally provided with a container; The container is internally provided with a placing cavity for containing a drying medium, the inner wall of the placing cavity is provided with a vent hole, and the container is configured to communicate the closed cavity in the cover body with the placing cavity by using the vent hole, so that the drying medium adsorbs water vapor in the gas in the cover body. The container is internally provided with a placing cavity for placing a drying medium, and the placing cavity is communicated with the closed cavity in the cover body through the vent hole, so that water vapor in gas in the cover body can be adsorbed, the drying of the environment in the cover body is ensured, the measurement accuracy of the electronic balance is effectively prevented from being influenced by the water vapor, and the reliability of weighing and measuring of the electronic balance is improved.
