Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Example 1

Referring to fig. 1 to 3, the present embodiment provides a simple glove box including:

a box body 1. The box body 1 is made of transparent material. A glove operation opening 2 is arranged on one side wall of the box body 1. The bottom plate of the box body 1 is provided with a cover opening 12 at one side close to the glove operation opening 2. The box body 1 is provided with an exhaust port (not numbered in the figure) at one side far away from the glove operation port 2, and the exhaust port is suitable for being communicated with a harmful gas treatment device through an exhaust pipeline 5.

In the simple glove box of the embodiment, a container port (not shown) of the solution to be prepared can be covered by the cover port 12 of the box body 1, and the glove operation port 2 on the box body 1 is used for operation, so that harmful gas generated during the preparation of the solution, such as HCl gas generated during the preparation of concentrated hydrochloric acid, is limited in the box body 1. After the solution preparation is completed, gas in the box can enter the exhaust pipeline 5 through the exhaust port and be treated by a subsequent harmful gas treatment device. In addition, the case body 1 made of transparent materials is convenient for personnel to observe the conditions in the case body 1 during operation, and is favorable for the accuracy of operation. Through the use of simple glove box, can reduce personnel to the dependence of protective equipment such as goggles, save operating personnel's preparation operation, improve the operating efficiency, alleviate personnel's operation burden simultaneously.
