Embodiment 1

[0055] Figure 6a , Figure 6b It is a front view and a top view of an additional embodiment 1 of the present invention, Figure 7a , Figure 7b It is an illustration diagram of the use state of the additional embodiment 1 of the present invention.

[0056] With reference to the accompanying drawings, the harmful gas purification device of the additional embodiment 1 includes a cover assembly 50, which seals the suction portion 11 on the remaining side except the side of the outer cover 20 provided with the above-mentioned local exhaust pipeline portion 30 to improve the local exhaust pipeline portion. 30 suction efficiency.

[0057] For this reason, in the above-mentioned harmful gas purifying device, the main body 10 is formed by a polygonal cylindrical body (in the embodiment, a planar quadrangular cylindrical body), and in order to be able to attach the magnetic body 53 of the cover assembly 50 described later, at least the main body is formed. The section of the sucti...

Embodiment 2

[0065] Figure 8 It is a front view of an additional embodiment 2 of the present invention, Figure 9 It is the front view of the cover of the additional embodiment 2 of the present invention, Figure 10 It is a top view of an outer cover of an additional embodiment 2 of the present invention, Figure 11 It is a side view of the cover of the second additional embodiment of the present invention.

[0066] Referring to the accompanying drawings, the harmful gas purifying device of the second embodiment is added in such a way that the door assembly 40 of the local exhaust pipeline part 2 is arranged on the outer cover 20 instead of on the suction pipe 31 .

[0067] The above-mentioned door assembly 40 is formed by a rail 41 , a door 42 and a rod 43 .

[0068] The rails 41 are disposed on both sides of the joint end of the local exhaust line portion 30 on the inner surface of the cover 20 coupled with the local exhaust line portion 30 . Specifically, the rail 41 has a substant...

Embodiment 3

[0072] Figure 12 It is an illustration diagram of an additional embodiment 3 of the present invention.

[0073] Referring to the accompanying drawings, the harmful gas purifying device of the additional embodiment 3 is a structure in which the door 42 of the door assembly 40 exemplified in the additional embodiment 2 slides through external signal input (electrical signal input or hydraulic pressure / pneumatic signal input). Therefore, the above-mentioned door assembly 40 additionally includes a cover 45 and a door driving source 46 .

[0074] The cover 45 is coupled to the outer surface of the cover 20 where the slit 21 is formed so as to cover the slit 21 and the rod 43 . In this case, the cover 45 prevents leakage of harmful gas through the slit 21 of the cover 20 formed as a space for the rod 43 to move, and provides a space for installing a door driving source 46 described later.

[0075] The door driving source 46 is provided inside the cover 45 and combined with the l...

Abstract

In a harmful gas purification device of the present invention, an inhalation part for collecting harmful gas is provided at the lower end of a main body. A filter unit that filters and purifies harmful gases is provided on the upper side of the above-mentioned suction unit. A purified air discharge unit for discharging purified air to the outside is provided on the upper side of the filter unit. The above-mentioned harmful gas purification device with a local exhaust function includes: an outer cover, which is combined with the outer surface of the main body where the suction part is formed, and communicates with the suction part inside the main body; a local exhaust pipeline part which is combined with one side of the above-mentioned outer cover, makes the suction pipe formed in a long way, so that the user can exhaust harmful gas at a specific location, and a collection end that can collect harmful gas at a specific location is formed at the end.

Description

technical field [0001] The invention relates to a harmful gas purifying device with local exhaust function. [0002] In detail, the present invention improves a device for collecting and purifying harmful gases in places such as laboratories or workshops that are easily exposed to various chemical substances, and in particular, the present invention relates to the following harmful gases with a local exhaust function Purification device, that is, adding a local exhaust unit that allows the user to inhale the harmful gas generated in the specific location required, thereby providing an addition to the original function of collecting and purifying harmful gas in a wide area An additional function to collect and purify harmful gases at a specific location. Background technique [0003] Generally, for example, harmful gas purification equipment removes harmful gases generated during processes and experiments at industrial sites such as chemical, agrochemical, and pharmaceutical...
