Description

Technical Field

[0001] This utility model relates to the field of computer cleaning technology, and more specifically, to a computer chassis dust removal device. Background Technology

[0002] A computer case typically includes the outer shell, bracket, and various switches and indicator lights on the front panel. As a component of a computer, its main function is to house and secure various computer parts, providing support and protection. Due to the unpredictable environment in which computer cases are used, a large amount of dust accumulates inside after prolonged use. To prevent dust buildup from affecting the normal operation and heat dissipation of the components inside, it is necessary to clean the case and its internal components periodically. Current cleaning procedures generally involve using a brush to initially clean the dust inside the case, followed by using a blower to blow the dust out of the case. However, both brushing and blowering release a large amount of dust into the outside air, causing operators to inhale a significant amount of dust during operation, resulting in respiratory discomfort and impacting their health. Utility Model Content

[0003] The present invention aims to provide a computer chassis cleaning device to solve the problem in the prior art that a large amount of dust easily drifts to the outside when operators clean the chassis, which is detrimental to the health of the operators.

[0004] The embodiments of this utility model are implemented as follows:

[0005] This utility model provides a computer chassis dust removal device, which includes a base;

[0006] The top of the base is provided with a glass frame, and one end of the glass frame near the base is snapped into the top of the base;

[0007] The base has a cavity inside, and a number of support rods are provided inside the cavity. The support rods are parallel to each other and spaced apart. The two ends of the support rods are vertically fixed to the two sides of the base.

[0008] The bottom of several of the aforementioned support rods is provided with a dust filter assembly, and the outer edge of the dust filter assembly abuts against the inner wall of the aforementioned cavity;

[0009] A blower is provided on one side of the base. The air inlet of the blower is connected to the cavity inside the base. A brush is provided inside the glass frame. The axis of the brush has a ventilation channel, which is connected to the air outlet of the blower.

[0010] The glass frame has a first opening on the side near the blower, and a dust cover is sealed to the first opening.

[0011] In use, firstly, the glass frame is removed from the base. Secondly, the operator moves the chassis to the top of the base and places it on the support rods inside the cavity. The glass frame is then placed over the base, and the blower is started. The operator's hand passes through the dust cover on the first opening. Then, the operator grabs the brush inside the glass frame to scrub the chassis. The blower provides air intake for the ventilation duct. When the brush cleans the dust from the chassis, the air blown out of the ventilation duct agitates the brushed-off dust, causing it to accumulate on the dust cover through the blower's suction, preventing dust from drifting to the outside and affecting the surrounding environment and the operator's health.

[0012] The computer chassis cleaning device disclosed in this embodiment allows the chassis to be cleaned inside the glass frame by the brushes, as the glass frame covers the base. Simultaneously, the circulating air from the blower blows away the dust, improving cleaning efficiency. This results in a computer chassis cleaning device that is less likely to cause dust to drift to the outside, is beneficial to the health of operators, has high cleaning efficiency, and is easy to operate.

[0013] Optionally, the top of the base is provided with a slot, the slot extends and closes along the circumference of the base, and one end of the glass frame near the base is located in the slot.

[0014] This design, by utilizing the aforementioned slots, effectively restricts the glass frame, preventing it from shifting or sliding and thus affecting its dust-proofing effect.

[0015] Optionally: the dust cover has a pocket ring, the pocket ring is sealed to and limited to the first opening, the pocket ring is provided with a conical bag on the side near the glass frame, the conical bag has a second opening at the end away from the pocket ring, the second opening is provided with an elastic band along the ring, and the end of the conical bag near the pocket ring is fixedly connected to the pocket ring.

[0016] This design makes the dust cover easy to install and remove at the first opening. The conical shape of the bag makes the dust cover gradually narrower as it approaches the operator's wrist, which helps to seal it. The elastic band at the first opening can accommodate operators with different arm sizes, making the dust cover more versatile.

[0017] Optionally, the base has a plurality of support feet at its bottom end, and the plurality of support feet are evenly distributed at the bottom end of the base and vertically fixed to the bottom end of the base.

[0018] With this configuration, the aforementioned support feet raise the base too high, preventing the base from directly contacting the ground or operating table, effectively protecting the dust removal device and extending its service life.

[0019] Optionally, some of the above-mentioned support rods are cylindrical structures.

[0020] This design allows dust that falls onto the aforementioned support rods to easily slide onto the aforementioned dust filter assembly, effectively preventing dust from accumulating and remaining on the dust filter assembly.

[0021] Optionally: A slot is provided at one end of the base, the slot extends through one end of the base along the horizontal direction, and the dust filter assembly is slidably connected to the slot;

[0022] The aforementioned dust filter assembly has a frame, a filter screen inside the frame, a handle at one end of the frame near the slot, and the frame and the slot slide together.

[0023] With this configuration, the slot and the dust filter assembly work together, making it easy for the operator to grab the handle and pull it to remove the filter screen for dust cleaning. The frame ensures that the filter screen is always in the extended state, improving the structural stability of the dust filter assembly and facilitating the filter screen to catch dust falling from the upper part of the support rods.

[0024] Optionally: The blower is provided with a base plate at its bottom, one end of which is vertically fixed to the outer side wall of the base, and the blower is fixedly connected to the base plate.

[0025] This configuration allows the blower to be connected to the base plate and the base as a whole, which facilitates the overall handling of the equipment and ensures the stable operation of the blower.

[0026] Optionally: the brush has a bristle belt, a gripping belt is fixedly connected to the bristle belt in the axial direction, the ventilation channel passes through the bristle belt and the gripping belt in sequence, and an inner retaining ring is provided between the bristle belt and the gripping belt.

[0027] The inner wall of the glass frame is provided with a frame, one end of which has a notch, and the inner retaining ring is detachably engaged with the notch.

[0028] With this configuration, the inner retaining ring and the notch cooperate to allow the brush to be hooked onto the frame, the bristles to brush away dust inside the chassis, the gripping strap to facilitate the operator's gripping of the brush, and the air blown out of the ventilation duct to clean the dust brushed away by the bristles. The dust is then adsorbed by the blower and accumulated on the filter screen for centralized cleaning.

[0029] Optionally: The top of the glass frame is provided with a first pipe connector, which passes through the top of the glass frame and is limited to the top of the glass frame.

[0030] A third conduit is provided between one end of the first pipe connector near the inside of the glass frame and one end of the ventilation duct. One end of the third conduit is fixedly connected to the end of the first pipe connector near the inside of the glass frame, and the other end of the third conduit is fixedly connected to one end of the ventilation duct.

[0031] With this configuration, the third conduit between the first pipe connector and the brush allows the brush to be used more flexibly and conveniently, facilitating comprehensive dust removal of the chassis. At the same time, the third conduit guides air, and the first pipe connector facilitates the installation and removal of the glass frame from the base.

[0032] Optionally: the air inlet of the blower is connected to a first duct, the base has a through hole on the side near the blower, the through hole penetrates the side wall of the base and communicates with the cavity, and the end of the first duct away from the blower is sealed and connected to the through hole.

[0033] The air outlet of the blower is connected to a second pipe connector. The end of the second pipe connector away from the blower is sealed to a second conduit. The end of the second conduit away from the second pipe connector is detachably sealed to the end of the first pipe connector away from the glass frame.

[0034] With this configuration, when the blower is started, it draws in air filtered by the dust filter assembly from the bottom of the base through the first duct. The blower then guides the filtered air into the ventilation duct through the second pipe connector, the second duct, the first pipe connector, and the third duct, and blows it out from the end of the brush. This effectively blows away the dust, causing it to be adsorbed and accumulated on the dust filter assembly by the blower. Furthermore, the detachable connection between the second duct and the first duct connector facilitates the removal of the glass frame, allowing the machine to be placed on the support rods. The glass frame can then be replaced and the second duct and the first duct connector connected, making the assembly and disassembly of the glass frame more convenient.

[0035] Optionally, both the first guide tube and the second guide rod mentioned above are made of flexible tubing.

[0036] This design allows for easy connection between the first guide tube and the second guide rod, while also facilitating the replacement of different lengths according to the usage environment, thus expanding the range of applications.

[0037] Optionally, both the first and second pipe connectors mentioned above are flexible pipe joints.

[0038] This design gives the first and second pipe connectors a certain degree of flexibility, which helps to ensure the sealing of the pipe connections.

[0039] Optionally: The glass frame described above is made of transparent material.

[0040] This design allows operators to directly observe the cleanliness of the machine casing while cleaning it with the brushes, making it easier to adjust the brush angle.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0051] Example

[0052] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This embodiment proposes a computer chassis dust removal device, including a base 1;

[0053] A glass frame 2 is provided on the top of the base 1, and one end of the glass frame 2 near the base 1 is snapped into the top of the base 1;

[0054] The base 1 has a cavity 3 inside, and a number of support rods 4 are provided inside the cavity 3. The support rods 4 are parallel to each other and spaced apart. The two ends of the support rods 4 are vertically fixed to the two sides of the base 1.

[0055] A dust filter assembly 5 is provided at the bottom of several support rods 4, and the outer edge of the dust filter assembly 5 abuts against the inner wall of the cavity 3;

[0056] A blower 6 is provided on one side of the base 1. The air inlet of the blower 6 is connected to the cavity 3 inside the base 1. A brush 7 is provided inside the glass frame 2. The axis of the brush 7 has a ventilation channel 8, which is connected to the air outlet of the blower 6.

[0057] A first opening 9 is provided on the side of the glass frame 2 near the blower 6, and a dust cover 10 is sealed and connected to the first opening 9.

[0058] In use, firstly, the glass frame 2 is removed from the base 1. Secondly, the operator moves the chassis to the top of the base 1 and places it on several support rods 4 inside the cavity 3. The glass frame 2 is then placed over the base 1. The blower 6 is started, and the operator's hand passes through the dust cover 10 on the first opening 9. Then, the operator grabs the brush 7 inside the glass frame 2 to brush the chassis. The blower 6 provides air intake to the ventilation duct 8. When the brush 7 cleans the dust from the chassis, the air blown out of the ventilation duct 8 agitates the brushed-off dust, causing the dust to accumulate on the dust cover 10 through the adsorption of the blower 6, preventing the dust from drifting to the outside and affecting the surrounding environment and the health of the operator.

[0059] The computer chassis cleaning device disclosed in this embodiment allows the chassis to be cleaned inside the glass frame 2 by brush 7, as the base 1 is covered by a glass frame 2. At the same time, the dust is blown away by the circulating air of the blower 6, which improves the cleaning efficiency. Thus, the computer chassis cleaning device has the beneficial effects of preventing dust from being scattered to the outside, being beneficial to the health of operators, having high cleaning efficiency, and being easy to operate.

[0060] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The top of the base 1 has a slot 11 that extends and closes along the circumference of the base 1. The end of the glass frame 2 near the base 1 is located in the slot 11. The slot 11 is used to restrict the glass frame 2, preventing the glass frame 2 from shifting and sliding, which would affect the dust isolation effect.

[0061] The dust cover 10 has a pocket ring 12, which is sealed to and confined within the first opening 9. A conical bag 13 is provided on the side of the pocket ring 12 near the glass frame 2. The end of the conical bag 13 away from the pocket ring 12 has a second opening 14. An elastic band 15 is provided along the circumference of the second opening 14. The end of the conical bag 13 near the pocket ring 12 is fixedly connected to the pocket ring 12. This arrangement makes it easy to install and remove the dust cover 10 at the first opening 9. At the same time, the conical bag 13 makes the dust cover 10 gradually smaller near the operator's wrist, which is conducive to sealing. The elastic band 15 at the first opening 9 can accommodate operators with different arm sizes, making the dust cover 10 more widely applicable.

[0062] The base 1 has several support feet 16 at its bottom. The support feet 16 are evenly distributed at the bottom of the base 1 and vertically fixed to the bottom of the base 1. The support feet 16 raise the base 1 too high, preventing the base 1 from directly contacting the ground or operating table, effectively protecting the dust removal device and extending its service life.

[0063] The support rods 4 are all cylindrical, which makes it easy for dust falling onto the support rods 4 to slide onto the dust filter assembly 5, effectively preventing dust from accumulating and remaining on the dust filter assembly 5.

[0064] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A slot 17 is provided at one end of the base 1. The slot 17 passes through one end of the base 1 in the horizontal direction. The dust filter assembly 5 is slidably connected to the slot 17.

[0065] The dust filter assembly 5 has a frame 18, and a filter screen 19 is located inside the frame 18. A handle 20 is provided at one end of the frame 18 near the slot 17. The frame 18 and the slot 17 slide together, and the slot 17 cooperates with the dust filter assembly 5. This allows the operator to easily grasp the handle 20 and pull the handle 20 to remove the filter screen 19 of the dust filter assembly 5 for dust cleaning. The frame 18 ensures that the filter screen 19 is always in the unfolded state, which improves the structural stability of the dust filter assembly 5 and makes it easier for the filter screen 19 to catch the dust falling from the upper part of the support rods 4.

[0066] The blower 6 has a base plate 21 at its bottom. One end of the base plate 21 is vertically fixed to the outer wall of the base 1. The blower 6 is fixedly connected to the base plate 21. This arrangement allows the blower 6 to be connected to the base 1 as a whole through the base plate 21, which is beneficial for the overall transportation of the equipment. At the same time, it ensures that the blower 6 can operate stably.

[0067] The brush 7 has a bristle belt 22, and a gripping belt 23 is fixedly connected to the bristle belt 22 axially. The ventilation duct 8 passes through the bristle belt 22 and the gripping belt 23 in sequence. There is an inner retaining ring 24 between the bristle belt 22 and the gripping belt 23. A frame 25 is provided on the inner wall of the glass frame 2. One end of the frame 25 has a notch 26. The inner retaining ring 24 is detachably engaged with the notch 26. Through the cooperation of the inner retaining ring 24 and the notch 26, the brush 7 can be hooked on the frame 25. The bristle belt 22 can brush away the dust inside the machine box. The gripping belt 23 makes it easy for the operator to grip the brush 7. The air blown out by the ventilation duct 8 is convenient for cleaning the dust brushed away by the bristle belt 22. The dust is adsorbed by the blower 6 and accumulated on the filter screen 19 for centralized cleaning.

[0068] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The top of the glass frame 2 is provided with a first pipe connector 27, which passes through the top of the glass frame 2 and is limited to the top of the glass frame 2.

[0069] A third conduit 28 is provided between one end of the first pipe connector 27 near the inside of the glass frame 2 and one end of the ventilation duct 8. One end of the third conduit 28 is fixedly connected to the end of the first pipe connector 27 near the inside of the glass frame 2, and the other end of the third conduit 28 is fixedly connected to one end of the ventilation duct 8. The third conduit 28 provided between the first pipe connector 27 and the brush 7 makes the brush 7 more flexible and convenient to use, and facilitates the brush 7 to clean the chassis from all directions. At the same time, the third conduit 28 has the function of guiding air. The setting of the first pipe connector 27 makes it easy to assemble and disassemble the glass frame 2 on the base 1.

[0070] The blower 6 has a first duct 29 connected to its air inlet. The base 1 has a through hole 30 on the side near the blower 6, which penetrates the side wall of the base 1 and connects to the cavity 3. The end of the first duct 29 away from the blower 6 is sealed to the through hole 30. The blower 6 has a second pipe connector 31 connected to its air outlet. The end of the second pipe connector 31 away from the blower 6 is sealed to a second duct 32. The end of the second duct 32 away from the second pipe connector 31 is detachably sealed to the end of the first pipe connector 27 away from the glass frame 2. When the blower 6 is started, it can draw dust from the bottom of the base 1 through the first duct 29, which is then drawn by the dust filter assembly 5. Filtered air enters the blower 6, which then guides the filtered air into the ventilation duct 8 through the second pipe connector 31, the second duct 32, the first pipe connector 27, and the third duct 28, and blows it out from the end of the brush 7. This blows away the dust, causing it to be adsorbed and accumulated on the dust filter assembly 5 by the blower 6. At the same time, the detachable connection between the second duct 32 and the first duct connector 27 makes it easier for workers to remove the glass frame 2, allowing them to place the machine on several support rods 4, cover the glass frame 2, and connect the second duct 32 and the first duct connector 27, making the disassembly and assembly of the glass frame 2 more convenient.

[0071] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 Both the first conduit 29 and the second guide rod are made of flexible tubing, which makes it easy to connect the first conduit 29 and the second guide rod, and also allows for the replacement of different lengths according to the usage environment, thus expanding the range of applications.

[0072] Both the first pipe connector 27 and the second pipe connector 31 are flexible pipe joints, which gives the first pipe connector 27 and the second pipe connector 31 a certain degree of flexibility, making it easier to ensure the sealing of the pipe connection.

[0073] The glass frame 2 is made of transparent material, which allows the operator to directly observe the cleaning status of the machine casing when cleaning it with the brush 7. This makes it easier to adjust the cleaning angle of the brush 7. At the same time, it makes it easier to observe the degree of dust accumulation on the filter screen 19, so that the operator can easily remove the filter screen 19 and clean it in time.

[0074] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The specific operating principle of the computer chassis cleaning device in this embodiment is as follows:

[0075] When cleaning the chassis is required, the operator can separate the second duct 32 from the first duct connector 27 and remove the glass frame 2. Then, place the chassis to be cleaned on several support rods 4, cover it with the glass frame 2, connect the second duct 32 to the first duct connector 27, and start the blower 6. The air inlet of the blower 6 achieves the dust suction effect on the base 1 and the inside of the glass frame 2. Then, using the second opening 14 on the dust cover 10, the operator can reach into the glass frame 2, grab and remove the brush 7. While cleaning the hardware inside the chassis, the air from the blower 6 outlet can re-enter the glass frame 2 through the ventilation channel 8 opened in the center of the second duct connector 31, the second duct 32, the first duct connector 27, the third duct 28, and the gripping strap 23, thus blowing away the dust. The dust blown down is then adsorbed by the blower 6 and accumulated on the filter screen 19, so that the chassis cleaning can be carried out completely inside the glass frame 2, preventing dust from drifting to the outside.

[0076] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
