Description

Exhaust device and filter comprising same Technical Field Cross Reference to Related Applications The present application claims priority and benefit from korean patent application No. 10-2024-0105885 filed 8 at 8/2024, the disclosure of which is incorporated herein by reference in its entirety. The present invention relates to an exhaust device and a filter including the same. Background As the use of fossil fuels has grown rapidly, the demand for using alternative energy sources or clean energy sources is increasing, and as a part thereof, the field under study is the field of using electrochemical power generation and electric power storage. Currently, secondary batteries are representative examples of electrochemical devices that utilize such electrochemical energy, and the range of use thereof tends to be gradually expanded. Recently, with the development of technology and the increase in demand for mobile devices such as portable computers, portable phones, and cameras, the demand for secondary batteries has increased with the rapid increase in energy sources. Among such secondary batteries, many researches have been conducted on lithium secondary batteries that exhibit high charge/discharge characteristics, have long cycle life, are environmentally friendly, and have been commercialized and widely used. Such a lithium secondary battery is manufactured by integrating an electrode assembly including an electrode and a separator into a secondary battery case together with an electrolyte, and the electrode is manufactured by applying an electrode slurry including an active material onto a current collector, and then drying and rolling the resulting layer. At this time, in order to remove impurities generated during the process of mixing, transporting and supplying the electrode slurry, a filtering process is performed through a filter, and air generated in the filter must be removed. However, if the air generated in the filter is not sufficiently removed, air bubbles are contained inside the electrode slurry, which may adversely affect the quality of the electrode surface, and eventually cause a problem of deterioration of the performance of the secondary battery as a final product. Generally, in order to remove Air in the filter, an operator rotates an exhaust cover mounted to an upper end of the filter to perform Air discharge, and adjusts the amount of discharged Air (Air) according to the degree of rotation of the cover. Therefore, the exhaust cover used so far may have a problem in that it is impossible to exhaust a sufficient amount of air since the amount of air exhausted varies according to the empirical value of the operator. When the pressure within the filter is very high, it may cause stability problems with cap ejection. Accordingly, there is a need to develop a technology capable of solving the above-described problems of the related art. Disclosure of Invention Technical problem An object of the present invention is to provide an exhaust device capable of solving a stability problem such as ejection of a top cover while keeping the amount of air discharged constant, and a filter configured to be coupled with the exhaust device. Technical proposal According to an aspect of the present invention, there is provided an exhaust apparatus comprising: a main body unit having a diagonally shaped groove formed therein, and An insertion unit having a protrusion coupled to the diagonally shaped groove, Wherein a space is formed between the insertion unit and the main body unit due to movement of the protrusion in a state where the protrusion is coupled to the diagonally-shaped groove, and Wherein the diagonally shaped groove includes a first hooking groove at one side end and a second hooking groove at the other side end. According to another aspect of the present invention, there is provided a filter configured to be coupled with the above-described exhaust apparatus. Advantageous effects The protrusion of the insertion unit of the present invention discharges air while moving between the first and second hook-shaped grooves in a state of being coupled to the diagonally-shaped groove of the main body unit, there is an advantage in that a constant amount of air discharge can be maintained regardless of an operator's experience value and the air discharge device or the insertion unit is not ejected in a state of being coupled to the filter.
