Description

Dust excluding hood and welding equipment Technical Field The application belongs to the technical field of welding, and particularly relates to a dust hood and welding equipment. Background Modern intelligent manufacturing has certain requirements on the cleanliness class of laser welding, and the dust concentration needs to meet the limit requirements of welding equipment. In the prior art, a direct-insertion mode is adopted between the body of the dust hood and the communicating pipe, and the mode can lead to smaller dust-removing air suction port and lower dust-removing efficiency. Disclosure of utility model The embodiment of the application aims to provide a dust hood and welding equipment. According to a first aspect of an embodiment of the present application, there is provided a dust hood comprising: The body is internally provided with a cavity, the body is provided with a through hole, the through hole is communicated with the cavity, and the length of the through hole is larger than the width of the through hole; And the communicating pipe is arranged outside the cavity, is tangentially connected with the body and is communicated with the through hole. Optionally, the through hole is in a water drop shape. Optionally, the width of the through hole is 30mm-40mm. Optionally, the dust hood comprises four communicating pipes; Four through holes are formed in the body, the four through holes are arranged at intervals along the circumferential direction of the body, and the four communicating pipes are respectively communicated with the corresponding through holes. Optionally, the communicating pipe includes a first pipe and a second pipe, the first pipe is communicated with the through hole, the second pipe is connected with the first pipe, and an axis of the first pipe intersects with an axis of the second pipe. Optionally, axes of the first pipes of two adjacent communication pipes intersect. Alternatively, the axes of the first pipes of the two communicating pipes that are disposed at intervals are arranged at intervals in the radial direction of the body. Optionally, the body includes a first port and a second port, the first port having a diameter smaller than a diameter of the second port. Optionally, the dust hood further comprises a filter component, and the filter component is arranged in the body and located at the through hole. According to a second aspect of the embodiment of the application, there is provided a welding device, including the dust hood described above. The embodiment of the application has the technical effects that the length of the through hole is larger than the width of the through hole, and the communicating pipe is tangentially connected with the body, so that the dust removal area can be increased without increasing the dust removal air suction amount, and the dust removal efficiency is effectively improved.
