Description

Technical Field

[0001] The utility model relates to the technical field of dustproof chassis, in particular to a dustproof chassis of a computer. Background Art

[0002] The computer case is an indispensable computer component when using computers at home and at work. Various components contained in the computer are installed inside the case. As a result, a large amount of heat is generated inside the case during the use of the computer. Currently, in order to dissipate the heat inside the case, heat dissipation holes are opened on the case, and cooling fans are installed next to the heat dissipation holes. The cooling fans can blow external air into the case, thereby achieving the effect of heat dissipation and cooling.

[0003] However, when the computer case is not in use, dust floating in the air will fall into the inside of the case through the heat dissipation holes on the case, and when the cooling fan blows air into the inside of the case, the dust will also flow into the inside of the case with the airflow. This cannot provide a good dust-proof effect for the inside of the case. In order to prevent dust, the direction of the air blown by the cooling fan is changed so that the cooling fan blows the air inside the case to the outside. This will reduce the heat dissipation effect and cannot prevent the floating dust from naturally falling into the inside of the case when the computer is not in use. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] The technical problem to be solved by the utility model is that the current method of achieving dust prevention effect by driving the air inside the chassis to blow to the outside by a cooling fan will affect the heat dissipation effect, and it is also impossible to prevent the dust floating in the air from naturally falling into the chassis when the computer is not in use.

[0007] In order to solve the above technical problems, the technical solution provided by the utility model is: a dustproof case for a computer, comprising a case body, a dustproof heat dissipation mechanism and a mounting slot located at the bottom of the case body, the dustproof heat dissipation mechanism comprising a bottom plate cooperating with the mounting slot, the upper end of the bottom plate is fixedly connected to a frame plate, the upper end of the bottom plate is provided with a fixed side plate located on the outer side of the frame plate, a honeycomb sponge filter is inserted into the fixed side plate, the honeycomb sponge filter is provided with at least one and evenly arranged filter holes, the upper end of the fixed side plate is provided with a fixed mesh plate cooperating with the honeycomb sponge filter, the upper end of the fixed mesh plate is provided with a cooling fan driven by a motor, and the upper end of the fixed mesh plate is provided with a fan fixing frame cooperating with the cooling fan.

[0008] As an improvement, at least one evenly arranged partition plate is provided in the frame plate.

[0009] As an improvement, the fixed side plates are all connected to the fixed mesh plate and the bottom plate by threads.

[0010] As an improvement, the fixed mesh plate and the fan fixing frame are connected by threads.

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the advantages of the utility model are that: the sides and bottom of the chassis body are both sealed structures, the mounting groove at the bottom of the chassis body is installed with a dust-proof heat dissipation mechanism, the cooling fan can dissipate heat inside the chassis body, and on the premise of heat dissipation, the honeycomb sponge filter can also filter dust, and the dust-proof heat dissipation mechanism is located at the bottom of the chassis body during normal use, and it is difficult for floating dust to enter the chassis body from the dust-proof heat dissipation mechanism at the bottom, which can improve the dust-proof effect without affecting the heat dissipation function.

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] Embodiment 1

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Fig. 9 As shown, a dustproof case for a computer comprises a case body 1, wherein four corners of the bottom of the case body 1 are provided with legs 2, a dustproof heat dissipation mechanism 4 and a mounting slot 3 located at the bottom of the case body 1, and no through holes are provided on the four sides and the top of the case body 1, the dustproof heat dissipation mechanism 4 comprises a bottom plate 5 matched with the mounting slot 3, a frame plate 6 is fixedly connected to the upper end of the bottom plate 5, and at least one evenly arranged partition plate 7 is provided in the frame plate 6, and the partition plate 7 can play a role in guiding airflow.

[0028] Through the above structure, the bottom plate 5 can be installed in the installation groove 3 to achieve heat dissipation and dust prevention. The specific structure is as follows:

[0029] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9As shown, the upper end of the base plate 5 is provided with a fixed side plate 10 located on the outside of the frame plate 6, a honeycomb sponge filter 8 is inserted in the fixed side plate 10, and the honeycomb sponge filter 8 is provided with at least one and evenly arranged filter holes 9, the upper end of the fixed side plate 10 is provided with a fixed mesh plate 11 matched with the honeycomb sponge filter 8, the upper end of the fixed mesh plate 11 is provided with a cooling fan 12 driven by a motor, the upper end of the fixed mesh plate 11 is provided with a fan fixing frame 13 matched with the cooling fan 12, the fixed mesh plate 11 and the fan fixing frame 13 are threadedly connected, and the fan fixing frame 13 can be disassembled separately for easy maintenance of the fan.

[0030] Through the above structure, the dust-proof effect inside the chassis body 1 can be improved without affecting the heat dissipation effect.

[0031] Embodiment 2

[0032] like Figure 6 , Figure 7 and Figure 8 As shown, the fixed side plate 10 is connected to the fixed mesh plate 11 and the bottom plate 5 by threads, and inclined protrusions are provided on the four sides of the fixed side plate 10 .

[0033] Through the above structure, the honeycomb sponge filter 8 can be taken out separately from the fixed side plate 10 by disassembling the bottom plate 5 , and the inclined protrusion makes it convenient to grab the fixed side plate 10 .

[0034] During the specific implementation of the utility model, when the chassis body is used, the bottom plate of the dustproof heat dissipation mechanism is fixed in the installation groove, and the heat dissipation fan is extended into the interior of the chassis body. During the use of the chassis body, the four sides and the top of the chassis body are structures without openings, and dust will not enter the interior of the chassis body through the four sides and the top of the chassis body. The dustproof heat dissipation mechanism is located at the bottom of the chassis body. During normal use, dust naturally floating in the air is difficult to enter the interior of the chassis body from the bottom of the chassis through the dustproof heat dissipation mechanism.

[0035] During heat dissipation, the cooling fan rotates to blow external air into the chassis body. In the process of air flowing through the dust-proof heat dissipation mechanism, the honeycomb sponge filter and the partition plate cooperate to block the dust. The fixed side plate cooperates with the fixed mesh plate to fix the honeycomb sponge filter. When the honeycomb sponge filter needs to be replaced or cleaned, the bottom plate is removed and the honeycomb sponge filter can be taken out from the fixed side plate for replacement or cleaning. This can improve the effect of preventing dust from entering the chassis body without affecting the heat dissipation effect.
