Technical Field

[0001] This utility model relates to the technical field of blowers, and in particular to a blower protective structure suitable for outdoor environments. Background Technology

[0002] Blowers, as important pneumatic conveying equipment, are widely used in industrial production, environmental management, and municipal engineering. When used outdoors, existing blowers are often affected by external environmental factors such as rain, sunlight, insects, and dust. Traditional protection methods often involve building rain shelters or placing them indoors with extended air ducts and louvered structures, but these methods have the following problems: Complex structure and high processing cost; The waterproofing effect is limited; even small amounts of rainwater can still be sucked into the interior through the air inlet. Metal casings are prone to overheating under strong light, which affects blower efficiency and control system stability.

[0003] Once inhaled, flying insects accumulate around the filter element and are difficult to clean.

[0004] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a blower protection structure suitable for outdoor environments, making it more valuable for industrial use. Utility Model Content

[0010] As a further improvement of this utility model, the filter element is installed inside the inner cylinder through the filter element mounting bracket, and the servo motor is installed inside the inner cylinder through the motor mounting bracket.

[0011] As a further improvement of this utility model, elastic shock-absorbing pads are installed between the filter element and the filter element mounting bracket, and between the servo motor and the motor mounting bracket.

[0012] As a further improvement of this utility model, the insect-proof net is detachably installed on the inner cylinder outside several air inlets, and the insect-proof net is a honeycomb-shaped metal mesh or nylon mesh.

[0024] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. 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.

[0026] The first embodiment of this utility model: like Figures 1-2 As shown, this embodiment of a blower protection structure suitable for outdoor environments includes an outer shell and a blower assembly installed inside the outer shell. The blower assembly includes a servo motor 9, a controller 10, and a blower 11.

[0027] The outer casing consists of an outer cylinder 1 and an inner cylinder 2 arranged coaxially. The outer cylinder 1 is located on the top outside of the inner cylinder 2, thus forming an annular air gap between the outer cylinder 1 and the inner cylinder 2. This design not only provides a physical isolation barrier but also constitutes a special airflow channel.

[0028] The blower assembly is located at the bottom of the inner cylinder 2. A filter element 7 is installed inside the inner cylinder 2 above the blower assembly. Several air inlets are formed on the inner cylinder 2 above the filter element 7. An insect-proof net 6 is installed on the inner cylinder 2 outside the air inlets. The insect-proof net 6 is detachably installed on the inner cylinder 2 outside the air inlets. The insect-proof net 6 is a honeycomb-shaped metal mesh or nylon mesh with a pore size of less than 5mm, effectively blocking flying insects from entering without significantly affecting airflow. The detachable installation of the insect-proof net facilitates regular cleaning and maintenance.

[0029] External air enters through the air inlet channel at the bottom of the outer cylinder 1 and flows upward along the air gap between the outer cylinder 1 and the inner cylinder 2. After entering through the air inlet at the top of the inner cylinder 2, it flows downward through the filter element 7 and then to the blower assembly below.

[0030] The airflow path design in this embodiment: External air enters through the air inlet at the bottom of the outer cylinder, flows upward along the air gap between the outer and inner cylinders, forming the first flow path; after reaching the top, it enters the inner cylinder through the air inlet at the top, then flows downward through the filter element, and finally flows to the blower assembly at the bottom. This tortuous airflow path of "bottom in, top out, then bottom in again" effectively prevents the direct intrusion of rainwater and flying insects.

[0031] Several mounting feet 3 are installed at the bottom of the inner cylinder 2, and elastic damping pads are installed at the bottom of the mounting feet 3. The filter element 7 is installed inside the inner cylinder 2 via the filter element mounting bracket 8, and the servo motor 9 is installed inside the inner cylinder 2 via the motor mounting bracket 12. Elastic damping pads are installed between the filter element 7 and the filter element mounting bracket 8, and between the servo motor 9 and the motor mounting bracket 12. This forms a multi-layer damping system, effectively reducing vibration and noise during equipment operation.

[0032] Both the outer cylinder 1 and the inner cylinder 2 are made of stainless steel, and the outer side of the outer cylinder 1 is made of mirror, which can effectively reflect sunlight and reduce the temperature rise caused by solar radiation. At the same time, the annular space formed by the air gap not only serves to waterproof and prevent insects, but also constitutes a natural heat insulation layer to prevent the internal temperature from becoming too high.

[0033] The second embodiment of this utility model: like Figures 1-2 As shown, a blower protection structure suitable for outdoor environments in this embodiment mainly includes an outer shell, blower components, and related installation support structures.

[0034] The outer casing adopts a double-cylinder structure design, consisting of an outer cylinder 1 and an inner cylinder 2 coaxially. The outer cylinder 1 is located on the top outer side of the inner cylinder 2, with an appropriate gap between them to form an annular air gap. Both the outer cylinder 1 and the inner cylinder 2 are made of stainless steel, and the outer surface of the outer cylinder 1 is mirror-finished to enhance sunlight reflection.

[0035] The outer cylinder 1 and the inner cylinder 2 are detachably installed together: connected by clamps, bolts or flange structure, which facilitates assembly and maintenance.

[0036] The blower assembly is installed at the bottom of the inner cylinder 2 and includes a servo motor 9, a controller 10, and a blower 11. The servo motor 9 is fixed inside the inner cylinder 2 by a motor mounting bracket 12 to ensure operational stability.

[0037] A filter element 7 is installed inside the inner cylinder 2 above the blower assembly, and the filter element 7 is fixed by the filter element mounting bracket 8. The main function of the filter element 7 is to further filter fine particulate matter in the air and protect the internal components of the blower.

[0038] Several air inlets are provided at the top of the inner cylinder 2, and an insect-proof net 6 is installed on the outside of the air inlets. The insect-proof net 6 adopts a honeycomb structure and can be made of metal mesh or nylon mesh, with a pore size of less than 5mm, to ensure effective insect prevention without affecting ventilation.

[0039] The insect screen 6 can be detachably installed on the outside of the air inlet using clips or screws. When cleaning is required, simply loosen the fasteners to remove the insect screen for washing or replacement, making maintenance very convenient.

[0040] Several mounting feet 3 are installed at the bottom of the inner cylinder 2. The bottom of the mounting feet 3 is equipped with elastic shock-absorbing pads to effectively isolate the transmission of equipment vibration to the foundation.

[0041] An air outlet duct 4 is installed on one side of the bottom of the inner cylinder 2, which is connected to the internal blower 11 for outputting pressurized air. A gland 5 is installed on the other side for cable installation.

[0042] A brief description of the working process in this embodiment: Air intake stage: External air enters naturally from the air intake channel at the bottom of the outer cylinder 1 and flows upward along the air gap between the outer cylinder 1 and the inner cylinder 2; Initial protection: During the upward flow, raindrops in the air drip downwards due to gravity and will not enter the inner cylinder; flying insects and other debris are carried upwards by the airflow. Turning entry: After the air reaches the top of the inner cylinder, it enters the inner cylinder through the air inlet. At this time, the insect-proof net 6 effectively blocks flying insects from entering. Fine filtration: After air enters the inner cylinder, it flows downwards and passes through filter element 7, where fine particulate matter is filtered out. Blower operation: The filtered clean air enters the blower 11, is pressurized, and is output to the aeration system through the air outlet duct 4; Heat dissipation process: During equipment operation, the air gap forms natural convection, which carries away some of the heat; the mirrored outer cylinder reflects sunlight, reducing the internal temperature rise; Safety protection: A waterproof and breathable valve 13 is installed on the controller 10 to prevent the internal pressure from rising due to overheating after the controller is encapsulated.
