[0004] However, after long-term operation, the surface of existing equipment will accumulate a lot of dust. In order to reduce the impact of dust on the equipment, users need to separate the entire fan blade and filter screen connected by threads, which is time-consuming and laborious and affects maintenance efficiency.

[0005] Therefore, it is necessary to redesign and modify ventilation and cooling equipment that is easy to clean. Utility Model Content

It solves the problem that after long-term operation, the surface of existing equipment will accumulate a large amount of dust. In order to reduce the impact of dust on the equipment, users need to separate the entire threaded fan blade and filter screen, which is time-consuming, laborious, and affects maintenance efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a ventilation and cooling device that is easy to clean, including a base;

[0008] The base is provided with a bracket on the top, and a heat dissipation component is installed on the top of the bracket. Connecting blocks are fixedly connected to the top of the left and right sides of the base. A shielding frame is movably connected to the surface of the connecting block through a pin. The shielding frame is fitted onto the surface of the heat dissipation component and forms a protective cavity to shield the heat dissipation component. The base is provided with an opening and closing structure that can control the shielding frame to flip open and close.

[0009] As a preferred embodiment of this utility model, the opening and closing structure includes force-bearing rods fixedly connected to both sides of the connecting block, and a pressing plate fixedly connected to the surface of the bracket. Both sides of the pressing plate are in contact with the inner side of the force-bearing rod. When the pressing plate descends with the bracket, it can press the force-bearing rod so that it carries the shielding frame and flips and closes with the pin inside the connecting block as the axis.

[0010] As a preferred embodiment of this utility model, an electric telescopic rod is fixedly connected to the bottom of the base, the output end of the electric telescopic rod passes through the base and extends to the top of the base, and a connecting frame is fixedly connected to the output end of the electric telescopic rod, the top of the connecting frame being fixedly connected to the bottom of the extrusion plate.

[0011] In a preferred embodiment of this invention, the left and right sides of the extrusion plate are movably connected to pressure rollers via pins, and the outer surface of the pressure rollers contacts the inner side of the force-bearing rod.

[0012] As a preferred embodiment of this utility model, both sides of the base are fixedly connected to support legs, and the outer side of the force-bearing rod is fixedly connected to a spring plate.

[0013] As a preferred embodiment of this utility model, a buffer pad is fixedly connected to the outer side of the support leg, and the outer side of the buffer pad can contact the surface of the shielding frame after the shielding frame is flipped open.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model uses a shielding frame to cover the heat dissipation components to form a protective cavity, which effectively isolates external dust during equipment operation and prevents dust from directly adhering to the surface of the heat dissipation components, thereby reducing dust accumulation problems at the source. The opening and closing structure is linked with the shielding frame, eliminating the need for the cumbersome steps of disassembling threaded connectors in traditional equipment, and significantly shortening maintenance time.

[0016] 2. This utility model utilizes the vertical movement of the bracket to drive the extrusion plate to apply inward pressure to the force rod, and directly controls the closing of the shielding frame through the lever principle. The operation logic is simple and reliable.

[0017] 3. This utility model provides precise linear power through an electric telescopic rod, and transmits the power to the extrusion plate through a connecting frame, realizing the electric opening and closing of the shielding frame. Users only need to operate the button to complete the maintenance preparation, completely eliminating manual operation.

[0018] 4.

[0019] 5. In this utility model, the spring plate is compressed and stores elastic potential energy when the shielding frame is closed. When the electric telescopic rod releases the pressure, the spring plate quickly rebounds and pushes the force rod to reset, accelerating the opening action of the shielding frame.

[0020] 6. When the shielding frame is opened, the buffer pad makes flexible contact with the surface of the shielding frame to absorb the kinetic energy of the rollover and avoid deformation or noise caused by hard collision of metal parts. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 4 As shown, the present invention provides a ventilation and cooling device that is easy to clean, including a base 1;

[0028] The base 1 has a support 2 on its top, and a heat dissipation component 3 is installed on the top of the support 2. Connecting blocks 4 are fixedly connected to the top of the left and right sides of the base 1. A shielding frame 5 is movably connected to the surface of the connecting block 4 through a pin. The shielding frame 5 is fitted onto the surface of the heat dissipation component 3 and forms a protective cavity to shield the heat dissipation component 3. An opening and closing structure 6 is provided inside the base 1. The opening and closing structure 6 can control the shielding frame 5 to flip open and close.

[0029] refer to Figure 1 The opening and closing structure 6 includes force rods 7 fixedly connected to both sides of the connecting block 4. A pressing plate 8 is fixedly connected to the surface of the bracket 2. Both sides of the pressing plate 8 are in contact with the inner side of the force rod 7. When the pressing plate 8 descends with the bracket 2, it can press the force rod 7 so that it carries the shielding frame 5 and flips and closes with the pin inside the connecting block 4 as the axis.

[0030] As a technical optimization of this utility model, the vertical movement of the bracket 2 drives the extrusion plate 8 to apply inward pressure to the force rod 7, and the closing of the shielding frame 5 is directly controlled by the lever principle. The operation logic is simple and reliable.

[0031] refer to Figure 3 An electric telescopic rod 9 is fixedly connected to the bottom of the base 1. The output end of the electric telescopic rod 9 passes through the base 1 and extends to the top of the base 1. A connecting frame 10 is fixedly connected to the output end of the electric telescopic rod 9. The top of the connecting frame 10 is fixedly connected to the bottom of the extrusion plate 8.

[0032] As a technical optimization of this utility model, the electric telescopic rod 9 provides precise linear power, and the connecting frame 10 transmits the power to the extrusion plate 8 to realize the electric opening and closing of the shielding frame 5. Users only need to operate the button to complete the maintenance preparation, completely eliminating manual operation.

[0033] refer to Figure 3 The left and right sides of the extrusion plate 8 are movably connected to the pressure rollers 11 by pins, and the outer surface of the pressure rollers 11 is in contact with the inner side of the force rod 7.

[0034] As a technical optimization of this utility model, the pressure roller 11 uses rolling contact to replace the sliding friction between the extrusion plate 8 and the force rod 7, thereby reducing the movement resistance, making the support 2 move more smoothly, reducing the load on the electric telescopic rod 9, and extending the motor life.

[0035] refer to Figure 4 Both sides of the base 1 are fixedly connected to support legs 12. The outer side of the force-bearing rod 7 is fixedly connected to a spring plate. The side of the spring plate away from the force-bearing rod 7 contacts the inner side of the support leg 12. The spring plate is elastic.

[0036] As a technical optimization of this utility model, the spring plate is compressed and stores elastic potential energy when the shielding frame 5 is closed. When the electric telescopic rod 9 releases the pressure, the spring plate quickly rebounds and pushes the force rod 7 to reset, accelerating the opening action of the shielding frame 5.

[0037] refer to Figure 4 A buffer pad 14 is fixedly connected to the outer side of the support leg 12. The outer side of the buffer pad 14 can contact the surface of the shielding frame 5 after the shielding frame 5 is flipped open.

[0038] As a technical optimization of this utility model, when the shielding frame 5 is opened, the buffer pad 14 makes flexible contact with the surface of the shielding frame 5 to absorb the kinetic energy of the flipping and avoid deformation or noise caused by hard collision of metal parts.

[0039] The working principle and usage process of this utility model: When the electric telescopic rod 9 is in the retracted state, it drives the connecting frame 10 and the extrusion plate 8 to move downward. The extrusion plate 8 applies inward pressure to the force rod 7 through the pressure rollers 11 on both sides, forcing the force rod 7 to drive the shielding frame 5 to rotate inward around the pin axis and close, forming a sealed protective cavity, effectively preventing dust from entering the heat dissipation component 3. During this process, the spring plate is compressed and stores elastic potential energy close to the inside of the support leg 12. Meanwhile, the heat dissipation component 3 continues to operate, achieving ventilation and cooling. When it is necessary to clean the heat dissipation component 3, the user starts the electric telescopic rod 9, and its output end extends, pushing the connecting frame 10 and the extrusion plate 8 to move upward. The extrusion plate 8 disengages from the force rod 7, and the spring plate releases elastic potential energy, pushing the force rod 7 to reset outward, causing the shielding frame 5 to rotate outward around the pin axis and open, completely exposing the surface of the heat dissipation component 3. Maintenance personnel can directly clean or maintain the exposed heat dissipation component 3 without disassembling the threaded fan blades or filter screen, significantly improving efficiency.

[0040] In summary, this easy-to-clean ventilation and cooling device effectively isolates external dust during operation by using a protective cavity formed by a shielding frame 5 and a heat dissipation component 3, preventing dust from directly adhering to the surface of the heat dissipation component 3 and reducing dust accumulation at the source. The opening and closing structure 6 is linked with the shielding frame 5, eliminating the need for the cumbersome steps of disassembling threaded connectors in traditional equipment and significantly shortening maintenance time.
