[0002] With the rapid development of modern industry and technology, axial flow devices are increasingly used in the fields of ventilation, heat dissipation, air circulation, etc. Traditional axial flow devices usually adopt a single fan design, which can only achieve one-way air circulation, which is not enough in some occasions that require two-way ventilation, such as server rooms, large electronic equipment, etc. In addition, traditional axial flow devices also have shortcomings in dustproof design. The dustproof net is not installed firmly, is easy to fall off, and is not easy to replace, which to a certain extent affects the service life and performance stability of the axial flow device. Therefore, the development of an axial flow device that can achieve two-way circulation and has a stable dustproof net installation structure has become an urgent need in the industry.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0027] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0028] In an embodiment of the utility model, this case provides a bidirectional axial flow device, including two fans 100, a base 110 and a dustproof net 120. The base 110 is connected front to back, and the two fans 100 are respectively installed at the front end and the rear end of the base 110, and the two fans 100 are in opposite directions; the upper end of the inner wall of the base 110 is provided with two oppositely arranged clamping plates 200, the clamping plates 200 include a high plate 210 and a low plate 220, and the upper end of the dustproof net 120 is clamped between the high plate 210 and the low plate 220; the lower end of the inner wall of the base 110 is also provided with a transverse groove 300, and a locking platform 310 is provided in the transverse groove 300, and the lower end of the dustproof net 120 is installed in the locking platform 310.

[0029] Specifically, by installing fans 100 in opposite directions at the front and rear ends of the base 110, two-way air circulation is achieved. When forward wind flow is required, the fan 100 at one end of the base 110 is started, and the fan 100 at the other end is turned off. When reverse wind flow is required, the fan 100 at one end of the base 110 is turned off, and the fan 100 at the other end is started. This design not only improves the air circulation efficiency, but also can better adapt to the ventilation needs of different occasions, and improves the practicality of the axial flow device. By setting the clamping plate 200 and the locking platform 310, the dustproof net 120 is stably installed on the base 110. The high and low plate 220 design of the clamping plate 200 can effectively fix the upper end of the dustproof net 120, and the locking platform 310 can ensure the stable installation of the lower end of the dustproof net 120. This structural design makes the dustproof net 120 not easy to fall off, and improves the overall stability of the axial flow device.

[0030] In another embodiment of the utility model, the locking platform 310 includes a locking base 311, two elastic support arms 312 arranged opposite to each other, the two elastic support arms 312 are installed on the locking base 311, and an arc groove 313 is provided on the elastic support arm 312, and the groove bottoms of the two arc grooves 313 point in opposite directions. Specifically, the locking platform 310 forms a stable support structure through the locking base 311 and the two elastic support arms 312 arranged opposite to each other. This structure can effectively bear the weight of the lower end of the dustproof net 120 and the vibration that may be generated by the outside world, ensuring that the dustproof net 120 is not easy to loosen or fall off during long-term use. The arc groove 313 provided on the elastic support arm 312 is very cleverly designed. Since the groove bottoms of the arc groove 313 point in opposite directions, when the lower end of the dustproof net 120 is installed in the locking platform 310, the edge of the dustproof net 120 will naturally be clamped by the two arc grooves 313. This design not only enhances the stability of the installation of the dustproof net 120, but also enables the dustproof net 120 to be automatically positioned during the installation process, thereby simplifying the installation steps.

[0031] In another embodiment of the utility model, a connection cover 400 is provided between the fan 100 and the base 110. The connection cover 400 is in a hollow truncated cone shape, one end of the connection cover 400 is fixedly connected to the fan 100, and the other end is connected to the base 110. Specifically, the hollow design of the connection cover 400 allows air to pass smoothly, and its truncated cone shape can guide the air flow to a certain extent, so that the air circulation between the fan 100 and the base 110 is more uniform and efficient. This helps to improve the ventilation effect of the axial flow device and meet the needs of two-way circulation.

[0032] In another embodiment of the utility model, a plurality of first connection holes 500 are provided on the connection cover 400, and a plurality of second connection holes 510 are provided at the front and rear ends of the base 110, and a bolt passes through the first connection hole 500 and is threadedly connected with the second connection hole 510. Specifically, the bolt connection method is simpler and more convenient than other connection methods (such as welding or gluing). During the installation process, it is only necessary to pass the bolt through the first connection hole 500 on the connection cover 400 and threadedly connect it with the second connection hole 510 on the base 110. This design makes the installation process faster and more efficient, and reduces the difficulty and cost of installation.

[0033] In another embodiment of the utility model, two sets of dustproof nets 120 are provided in the base 110, and two sets are provided at corresponding positions of the clamping plate 200 and the locking platform 310. By providing two sets of dustproof nets 120, dust and impurities in the air can be more effectively prevented from entering the interior of the axial flow device. The superposition of the two sets of dustproof nets 120 doubles the dustproof effect, especially in harsh working environments, and can better protect the components inside the axial flow device from dust erosion and extend its service life.

[0034] In another embodiment of the utility model, two fans 100 are controlled separately, and the fan 100 includes a mounting frame 101 and a fan blade 102. One end of the mounting frame 101 is connected to one end of the connection cover 400, and the other end is connected to the ventilation cover 600. The mounting frame 101 is provided with a rotating fan blade 102. Specifically, the mounting frame 101 can better protect the fan blade 102 from rotating.

[0035] In another embodiment of the utility model, the dustproof net 120 is woven from a net rope 121, and the net rope 121 is woven into a square shape. The dustproof net 120 woven from the net rope 121 has a mesh structure that can effectively block dust, particles and other impurities in the air. After the net rope 121 is woven into a square shape, the mesh size of the dustproof net 120 is uniform, which can filter out most of the fine dust, ensure the cleanliness of the interior of the axial flow device, and thus extend its service life.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
