The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

Referring to fig. 1 to 6, a first embodiment of the present application provides a housing, which may be applied to various types of electronic devices such as a notebook computer, a server, a computer host, etc., and includes a housing 3 and a dust removing device disposed on an inner surface of the housing 3, where the dust removing device includes a support member 1 having a bearing portion and a dust removing member 2 fixedly connected to the bearing portion, the support member 1 is capable of being driven by force to make the bearing portion have at least a first station and a second station with respect to the housing 3, i.e., the bearing portion of the support member 1 is capable of changing positions with respect to the housing 3, the dust removing member 2 is used for removing dust on a fan 5 located inside the housing 3, and it should be understood that the fan 5 and the dust removing member 2 are located on the same side of the housing 3. It should be noted that "dust" herein is to be understood in a broad sense, and refers to any type of foreign matter that slowly accumulates on the fan 5 during normal use of the fan 5. When the bearing part is positioned at the first station, the dust removing part 2 is not contacted with the fan blades 51 rotated by the fan 5, namely the fan blades 51 cannot touch the dust removing part 2 in the rotating process; when the carrying part is located at the second station, the dust removing part 2 is contacted with the rotating fan blade 51, that is, the fan blade 51 can touch the dust removing part 2 in the rotating process. The dust removing member 2 has a contour shape matching the fan blade 51 on the side of the fan 5 in the axial direction thereof near the fan blade 51, as shown in fig. 4, which is a shape conforming to the contour of the fan blade 51 in the longitudinal section of the fan 5 (i.e., a plane passing through the rotation axis), for example, the upper edge of the fan blade 51 in fig. 4 is circular arc-shaped, and thus the side of the dust removing member 2 near the fan blade 51 is provided in circular arc-shape.

The supporting member 1 can be driven by force to change the working position of the bearing portion, and the driving manner of the supporting member can be various, as shown in fig. 3, in this embodiment, the supporting member 1 is pushed by an external object, for example, a card pin 4. In a preferred embodiment, the support 1 is provided as a spring having opposite first and second ends, the bearing portion being located at the first end, the second end being fixedly connected to the housing 3. Fig. 3 shows a state in which the carrying part is located at the first station, when the fan 5 needs to be dedusted, the card pin 4 can be used to push the dedusting piece 2 located at the carrying part of the supporting part 1 to the fan 5 through the first through hole 31 (see fig. 2), when the carrying part reaches the second station, the fan blades 51 rotated by the fan 5 can touch the dedusting piece 2, so that dust on the fan 5, especially dust which accumulates in the gaps between adjacent fan blades 51 and affects the air quantity, is swept down by the dedusting piece 2, and the swept dust is blown to a preset position under the action of the air flow of the fan 5, for example, is directly blown to the outside of the casing. After the dust removal is finished, the clamping pin 4 is pulled out of the first through hole 31, the supporting piece 1 is driven by the elastic restoring force of the supporting piece to enable the bearing part to be changed from the second station to the first station, and the dust removal piece 2 is not contacted with the rotating fan blade 51 when the bearing part is positioned at the first station, so that the normal work of the fan 5 is not influenced. According to the dust removal process, when the electronic equipment adopting the casing of the application needs to remove dust from the fan 5 in the casing, a user does not need to detach the casing, so that the trouble of disassembling parts is avoided, and the parts are prevented from being damaged by disassembling operation. Therefore, the shell can enable a user to conveniently and rapidly finish dust removal of the fan 5 inside the electronic equipment.

As shown in fig. 5 and 6, in order to achieve a better dust removing effect, the dust removing member 2 is configured as a brush, the brush has a plurality of bristles 21 arranged at intervals, the bristles 21 of the same cluster are arranged along a preset line shape, the rotating fan blades 51 sequentially pass through each cluster of bristles 21, and the preset line shape is consistent with the extending trend of the fan blades 51 along the radial direction of the fan 5. In this embodiment, the blades 51 extend outward from one end near the rotation center of the fan 5 in an arc trend, all the blades 51 are in a swirl shape as a whole in fig. 6, the bristles 21 of the dust removing member 2 are arranged in clusters corresponding to the extending trend of the blades 51 in accordance with the arc trend, and the intervals between the clusters are identical to the intervals between the adjacent blades 51, so that when one blade 51 passes through the dust removing member 2 with the rotation of the fan 5, the blade 51 will be sequentially overlapped with each cluster of bristles 21, and when the fan 5 rotates to this point, the cluster of bristles 21 are respectively overlapped with one blade 51, taking the moment illustrated in fig. 6 as an example. In other embodiments, the fan blades 51 may extend in other shapes along the radial direction of the fan 5, for example, the fan blades 51 extend outward in a straight line from one end near the rotation center of the fan 5, and all the fan blades 51 are in a radial shape. In addition, the dust removing member 2 may be provided in other types, for example, the dust removing member 2 is made of a soft material such as rubber, in addition to the brush.

In view of the disadvantage that the foreign objects such as the card pin 4 are lost or not easy to find, in a preferred embodiment, the dust removing device may include a movable member movably disposed relative to the housing 3, for example, the movable member is slidably connected to the housing 3, and the user applies the driving force to the support member 1 through the movable member. Since the movable member is arranged on the housing 3 or other parts of the electronic device, it is always kept together with the electronic device, so that the user does not have to find an extra object to drive the support member 1. In order to cooperate with the movable member, a force receiving portion may be provided on a side of the support member 1 facing away from the dust removing member 2, and the movable member may be configured to be movable relative to the housing 3 in a first direction perpendicular to an axial direction of the fan 5, so as to apply a force for driving the support member 1 to the force receiving portion by the movable member, for example, the movable member is configured as a slider having a wedge portion, and is slidably engaged with the housing 3, and a user can push the movable member to slide from an outer side of the housing 3 in a direction parallel to a surface of the housing 3, so that the wedge portion thereof is wedged between the support member 1 and the housing 3 in fig. 3, and the dust removing member 2 is forced to move toward the fan 5. Alternatively, the movable member may be configured to be movable relative to the housing 3 in a second direction parallel to the axial direction of the fan 5, so as to apply a force to the force receiving portion by the movable member to drive the support member 1, for example, the movable member may be configured as a button, slidably coupled to the housing 3, and the user may press the movable member from outside the housing 3 to slide in a direction perpendicular to the surface of the housing 3, so as to push the dust removing member 2 against the fan 5.

As shown in fig. 2 and 3, in the embodiment in which the housing 3 is provided with the first through hole 31 into which the foreign objects such as the card pin 4 are inserted, in order to avoid the entry of the external dust from the first through hole 31, a plugging portion adapted to the first through hole 31 may be disposed on a side of the dust removing member 2 close to the first through hole 31, and when the bearing portion of the supporting member 1 is located at the first station, the plugging portion is located in the first through hole 31. In order to make the outer surface of the electronic device take on a regular structure, the dust removing device is preferably provided with: when the bearing part of the support piece 1 is positioned at the first station, the end face of the blocking part of the dust removing piece 2 is flush with the outer surface of the shell 3. In addition, the terminal surface of shutoff portion can be provided with the concave structure that is used for fixing a position the external object, uses card needle 4 to push away dust removal piece 2 back to fan 5 like this, is difficult for appearing skidding between card needle 4 and the terminal surface of shutoff portion to ensure that dust removal piece 2 position is motionless. In order to minimize the occupation of the internal space of the electronic device, in this embodiment, when the carrying portion is located at the first station, the supporting member 1 is closely attached to the inner surface of the housing 3, as shown in fig. 3.

Referring to fig. 7 to 9, a second embodiment of the present application provides a housing, and the main difference between the second embodiment and the first embodiment is that the second embodiment is provided with a first elongated hole 11 at a first end of the supporting member 1, that is, an end not fixedly connected with the housing 3, and meanwhile, a limit post 32 slidably matched with the first elongated hole 11 is disposed on an inner surface of the housing 3, and the limit post 32 is fixed to the housing 3 and penetrates through the first elongated hole 11. The dust removing member 2 is disposed in the middle of the supporting member 1, preferably near the first elongated hole 11, as shown in fig. 8 and 9, when the clamping pin 4 passes through the first through hole 31 on the housing 3 to push the bearing part of the supporting member 1, i.e. the part connected with the dust removing member 2, to the aforementioned second station, i.e. the station for removing dust, the limit post 32 abuts against one end of the first elongated hole 11 away from the dust removing member 2, so that the problem that the dust removing member 2 is excessively displaced due to improper force control when the clamping pin 4 is used by a user, and then the fan blade 51 contacted with the dust removing member 2 is damaged is avoided. Furthermore, when the supporting member 1 is configured as a spring, the positioning post 32 and the first elongated hole 11 further avoid the problem that the supporting member 1 cannot rebound due to excessive deformation. Therefore, the spacing post 32 and the first strip hole 11 can make the dust removing device safer and more reliable to use. It should be noted that, the end of the limiting post 32 away from the housing 3 is provided with an expansion portion that is blocked outside the first elongated hole 11, so that the supporting member 1 cannot be separated from the limiting post 32. It is to be understood that, in other embodiments, the second end of the supporting member 1 may be not fixedly connected to the housing 3, but configured in the same manner as the first end, that is, the two ends of the supporting member 1 are provided with the first elongated holes 11 and pass through the limit posts 32 at the corresponding positions, so that the problem of preventing the excessive displacement of the dust removing member 2 can be also achieved.

As shown in fig. 12, the bearing portion is located at an end of the support member 1 away from the elastic member 13, and the guide member 35 has a guide surface disposed obliquely to the first direction. The dust removing member 2 is connected to the carrying part, the guiding surface of the guiding member 35 may be configured as a slope surface or an arc surface, which forms a slope surface on the moving path of the supporting member 1, fig. 12 shows a state when the carrying part of the supporting member 1 is in the first station, when the carrying part needs to be switched to the second station for dust removing, a user can apply a force to the part of the supporting member 1 exposed on the outer surface of the housing 3, so that the supporting member 1 moves to the right side of fig. 12, when the supporting member 1 passes through the guiding member 35, the guiding member 35 slides along the guiding surface, and the guiding member 35 forces the supporting member 1 to bend and deform due to the inclined arrangement of the guiding surface relative to the first direction, i.e. the initial moving direction of the supporting member 1, so that the dust removing member 2 moves away from the inner surface of the housing 3 and finally contacts with the rotating fan blade 51.

As shown in fig. 10 and 11, in order to facilitate the user to operate the support member 1 to move from the outside of the housing 3, a protrusion 12 may be provided to slidably engage with a second elongated hole 34 provided in the housing 3, the protrusion 12 being fixedly connected to the support member 1, and the length direction of the second elongated hole 34 being parallel to the aforementioned first direction.
