Description

Technical Field

[0001] The present invention relates to the technical field of electronic warehouse sealing, and in particular to an electronic warehouse constant pressure sealing structure. Background Art

[0002] Most electronic products are equipped with an electronic compartment. Electronic products used in special environments, such as floor scrubbers, have high requirements for the waterproof performance of their electronic compartments. In the prior art, electronic compartments are mostly composed of a compartment body and a compartment cover. Electronic components are arranged in the compartment body, and the compartment cover is a sealing cover arranged at the top opening of the compartment body. In actual use, it is found that electronic components generate a lot of heat when working. The volume of a traditional electronic compartment is fixed. In an electronic compartment with a fixed volume, the temperature rises and the pressure increases. At this time, a pressure difference is formed inside and outside the electronic compartment. Over time, the connection between the compartment cover and the compartment body will produce a gap under the action of the internal and external pressure difference, which is prone to water vapor leakage, and ultimately affects the service life of the electronic components.

[0003] Therefore, in view of the shortcomings of the existing technology, it is necessary to design an electronic compartment constant pressure sealing structure to solve the above problems. Summary of the invention

[0004] In order to overcome the above-mentioned deficiencies in the prior art, the present invention aims to provide an electronic compartment constant pressure sealing structure.

[0005] To achieve the above-mentioned purpose and other related purposes, the technical solution provided by the present invention is: a constant pressure sealing structure of an electronic warehouse, including a warehouse body, a warehouse cover and an elastic membrane, the warehouse body is used to assemble electronic components, the elastic membrane seal is covered on the top opening of the warehouse body, the warehouse cover is covered on the top opening of the warehouse body, and the warehouse cover is provided with an air vent connected to the outside.

[0006] The preferred technical solution is: a circle of embedding groove is provided on the edge of the top opening of the warehouse body, the elastic membrane covers the top opening of the warehouse body and the edge covers the embedding groove, and also includes a sealing ring, which is embedded in the embedding groove and presses the edge of the elastic membrane.

[0007] The preferred technical solution is: two first connecting ears arranged opposite to each other are provided on the outer wall of the bin body, and two second connecting ears arranged opposite to each other are provided on the outer wall of the bin cover, and the first connecting ears and the second connecting ears are arranged correspondingly and are detachably fixedly connected by bolts.

[0008] The preferred technical solution is: the groove bottom of the embedding groove is provided with multiple groups of ring edges, the bottom side of the sealing ring is provided with multiple groups of ring grooves, and the ring edges and the ring grooves are arranged to match each other.

[0009] Due to the application of the above technical solution, the present invention has the following beneficial effects: The present invention proposes a constant pressure sealing structure for an electronic warehouse, which covers the top opening of the warehouse with an elastic film so that when the temperature inside the warehouse rises and the air pressure becomes high, the volume inside the warehouse can be adaptively adjusted to keep the air pressure inside and outside the warehouse balanced, thereby avoiding the problem of water vapor penetration caused by the pressure difference between the inside and outside of the warehouse. The structure is simple and has outstanding effects. It can perfectly solve the problem of water vapor penetration into the electronic warehouse due to the pressure difference between the inside and outside of the electronic warehouse, and is suitable for popularization and use.
