[0009] In one or more embodiments, the dust collector cover may include a base portion attached to a main housing of the dust collector. The dust collector cover may include a first opening and closing portion connected to the base portion. The first opening and closing portion may be changeable between a state facing a first portion of the dust collector and a state not facing the first portion. The dust collector cover may include a second opening and closing portion connected to the base portion. The second opening and closing portion may be changeable between a state facing a second portion of the dust collector and a state not facing the second portion.

[0010] In the above configuration, the dust collector cover prevents the dust collector and objects around the dust collector from being damaged. The dust collector cover includes a base portion attached to the main body housing of the dust collector, a first opening / closing portion connected to the base portion, and a second opening / closing portion connected to the base portion. When a user wants to handle the first part of the dust collector, the user can handle the first part by opening the first opening / closing portion so that the first opening / closing portion does not face the first part without removing the entire dust collector cover from the dust collector. Similarly, the user can handle the second part by opening the second opening / closing portion so that the second opening / closing portion does not face the second part without removing the entire dust collector cover from the dust collector. Since the user can handle each of the first and second parts of the dust collector without removing the entire dust collector cover from the dust collector, the usability of the dust collector is prevented from being deteriorated.

[0011] In one or more embodiments, the dust collector may have a dust collection chamber and a dust box cover that opens and closes the dust collection chamber. The first part may include the dust box cover.

[0012] In the above configuration, the user can handle the dust box cover by opening the first opening / closing part without removing the entire dust collector cover from the dust collector. For example, the user can open the dust box cover to replace the dust collection bag placed in the dust collection chamber or to perform maintenance on the dust collection chamber.

[0013] In one or more embodiments, the dust collector may have a battery mounting portion to which the battery pack is attached. The second portion may include the battery mounting portion.

[0014] In the above configuration, the user can handle the battery mounting part or the battery pack by opening the second opening / closing part without removing the entire dust collector cover from the dust collector. For example, the user can mount the battery pack in the battery mounting part, remove the battery pack from the battery mounting part, and perform maintenance on the battery mounting part.

[0015] In one or more embodiments, the dust collector may have an operating unit connected to the main housing via an electrical cord, and the base portion may have a first opening through which the electrical cord is disposed.

[0016] In the above configuration, the first opening is provided in the base portion, so that the main body housing and the operation unit are connected via the electric cord with the dust collector covered with the dust collector cover.

[0017] In one or more embodiments, the body housing may include an exhaust port, and the base portion may include a second opening in which the exhaust port is disposed.

[0018] In the above configuration, since the second opening is provided in the base portion, the air discharged from the exhaust port can smoothly flow out to the periphery of the dust collector cover.

[0019] In one or more embodiments, the dust collector cover may include a mesh member disposed in the second opening.

[0020] In the above configuration, since a mesh member is disposed in the second opening, the exhaust port is protected by the mesh member. In addition, the mesh member prevents foreign matter around the dust collector cover from entering the internal space of the main housing through the exhaust port. Air discharged from the exhaust port can smoothly flow out around the dust collector cover through the mesh member.

[0021] In one or more embodiments, the dust collector cover may include a first joint portion that releasably joins the first opening / closing portion and the base portion. The dust collector cover may include a second joint portion that releasably joins the second opening / closing portion and the base portion.

[0022] In the above configuration, the first opening / closing part and the base part are joined by the first joint part, and the second opening / closing part and the base part are joined by the second joint part, so that the dust collector is covered with the dust collector cover. The first opening / closing part is released from the base part, so that the user can open the first opening / closing part. The second opening / closing part is released from the base part, so that the user can open the second opening / closing part.

[0023] In one or more embodiments, the base portion may include a woven portion. The base portion may include an elastic portion.

[0024] In the above configuration, the woven fabric portion sufficiently protects the main housing while suppressing an increase in the thickness of the base portion. The expandable portion allows the base portion to be deformed to match the outer shape of the main housing. For example, even if a part of a battery pack attached to the battery attachment portion protrudes from the surface of the main housing, the expandable portion can expand and contract to match the amount of protrusion of the battery pack.

[0025] In one or more embodiments, at least one of the base portion, the first closure, and the second closure may be formed from a high visibility material.

[0026] In the above configuration, at least a portion of the dust collector cover is made of a highly visible material, so that third parties around the user at a work site where the dust collector is used can easily recognize the presence of the user.
