Description

Technical Field

[0001] The present invention relates to the technical field of fans, in particular to a fan. Background Art

[0002] In hot weather or environment, in order to relieve the discomfort caused by high temperature, stuffiness and poor air circulation, people usually use electrical appliances such as fans to drive air flow, thereby improving human comfort. Common fans on the market are usually standing or sitting. In some special environments, such as offices and other environments with small personal space, standing or sitting fans usually take up a large space and are not suitable for use. Other common handheld or clamped fans, although small in size, have a fixed air outlet direction and cannot meet the different usage needs of users, resulting in poor user experience. Summary of the Invention

[0003] In view of this, it is necessary to provide a fan with better user experience.

[0004] An embodiment of the present invention provides a fan, comprising a fan body and a magnetic base. The fan body comprises a housing having a fan receiving chamber and a fan assembly located in the fan receiving chamber, the fan assembly comprising a cross-flow fan arranged along a preset direction, the housing further comprising an air outlet connected to the fan receiving chamber, the cross-flow fan being used to blow air toward the air outlet; the magnetic base being used to support the fan body and comprising a base body, wherein the magnetic base further comprises a first magnetic member arranged on the base body or the base body is the first magnetic member, the fan body further comprises a second magnetic member or the housing is the second magnetic member, the second magnetic member being used to magnetically attract the first magnetic member, so as to achieve a magnetically detachable connection between the magnetic base and the fan body.

[0005] Compared with the prior art, the fan provided in the embodiment of the present invention, by arranging the first magnetic part on the magnetic base and arranging the second magnetic part magnetically attracted to the first magnetic part on the fan body, can realize a magnetic detachable connection between the magnetic base and the fan body, so that the air outlet range of the fan is wider, meeting the user's multi-directional air outlet and cooling needs, making the user more comfortable, and also easy to disassemble and connect, so that the fan is easy to carry, convenient for users to use, and better user experience. In addition, the fan assembly is stored in the fan storage cavity, making the fan safer and quieter when in use, and the structure of the entire fan is simpler and occupies less space. The fan assembly adopts the cross-flow fan, which can make the air outlet speed uniform and improve human comfort.

[0006] In one embodiment, the magnetic base includes a first magnetic member disposed on the base body, and the fan body further includes a second magnetic member disposed on the housing, and the second magnetic member is used to magnetically connect to the first magnetic member, so that the magnetic base and the fan body are magnetically detachably connected. By disposing the first magnetic member on the base body and the second magnetic member magnetically connected to the first magnetic member on the housing, the magnetic base and the fan body can be relatively rotated to achieve a magnetic detachable connection in a variety of different relative positions, thereby adjusting the air outlet direction of the fan body, so that the fan has a wider air outlet range, meets the user's multi-directional air outlet and cooling needs, and provides greater user comfort. At the same time, the fan is easy to disassemble and connect, making it easy to carry and use, and providing a better user experience. At the same time, by rotating the magnetic base or the fan body to achieve a magnetic connection in a variety of different relative positions between the two, the air outlet direction of the fan body can be adjusted, which is convenient to operate. During the rotation process, the magnetic base and the fan body always maintain a magnetic connection, ensuring the safety and stability of the fan during operation.

[0007] In one embodiment, one of the first magnetic member and the second magnetic member is a permanent magnet, and the other of the first magnetic member and the second magnetic member is a permanent magnet or a soft magnet. By having one of the first magnetic member and the second magnetic member be a permanent magnet and the other of the first magnetic member and the second magnetic member be a permanent magnet or a soft magnet, the manufacturing process is easy, the manufacturing cost is low, and the manufacturing process is suitable for mass production.

[0008] In one embodiment, the housing includes a sidewall structure arranged around the preset direction and covering the outside of the cross-flow fan, and two end plates respectively connected to the two ends of the sidewall structure. The air outlet includes a strip-shaped air outlet arranged on the sidewall structure and extending along the preset direction. The housing also has an air inlet connected to the fan storage chamber. By providing the sidewall structure arranged around the preset direction and covering the outside of the cross-flow fan, and the two end plates respectively connected to the two ends of the sidewall structure, the cross-flow fan can be stored in the fan storage chamber surrounded by the sidewall structure and the end plates, so that the inlet and outlet air of the cross-flow fan are more concentrated. Moreover, by providing the air outlet in a strip shape, the air outlet can be matched with the outlet direction of the cross-flow fan, thereby improving the inlet and outlet efficiency of the cross-flow fan.

[0009] In one embodiment, there are multiple strip-shaped air outlets, and the multiple air outlets are arranged in a matrix along the preset direction and in a direction perpendicular to the preset direction. By providing multiple strip-shaped air outlets and arranging the multiple air outlets in a matrix along the preset direction and in a direction perpendicular to the preset direction, the air output of the fan can be made more uniform. At the same time, it can prevent users from accidentally inserting their fingers into the fan during use, causing injuries. It can also prevent dust, hair, and other debris from entering the fan and causing damage, thereby ensuring the safety of the fan during use.

[0010] In one embodiment, the air inlet is in the form of a strip extending along the preset direction, there are multiple air inlets, and the multiple air inlets are arranged in a matrix along the preset direction and in a direction perpendicular to the preset direction. By setting the air inlet in the form of a strip extending along the preset direction, the number of the air inlets is multiple, and the multiple air inlets are arranged in a matrix along the preset direction and in a direction perpendicular to the preset direction, the air intake of the fan can be made more uniform. At the same time, it can prevent users from accidentally inserting their fingers into the fan during use, causing injuries. It can also prevent dust, hair, and other debris from entering the fan and causing damage to the fan, thereby ensuring the safety of the fan during use.

[0011] In one embodiment, the side wall structure has a first outer surface located on the outside, and the base body has a second outer surface corresponding to the first outer surface. One of the first outer surface and the second outer surface includes an arc-shaped convex surface, and the other of the first outer surface and the second outer surface is an arc-shaped concave surface adapted to the arc-shaped convex surface. The arc-shaped convex surface and the arc-shaped concave surface are magnetically connected to each other through the first magnetic part and the second magnetic part, and the arc-shaped convex surface can rotate in the arc-shaped concave surface, so that the fan body rotates relative to the magnetic base, thereby adjusting the air outlet direction of the fan body. By including an arcuate convex surface on one of the first outer surface and the second outer surface, and the other of the first outer surface and the second outer surface being an arcuate concave surface adapted to the arcuate convex surface, the arcuate convex surface and the arcuate concave surface are magnetically connected through the first magnetic member and the second magnetic member, so that the magnetic connection between the fan body and the magnetic base is more secure, and the arcuate convex surface can move in the arcuate concave surface, so that the fan body moves relative to the magnetic base, thereby adjusting the air outlet direction of the fan body. The use of the arcuate surface can make the rotation between the two smoother, with less noise and easy operation.

[0012] In one embodiment, the cross-section of the first outer surface perpendicular to the preset direction is circular or teardrop-shaped. By setting the cross-section of the first outer surface perpendicular to the preset direction to be circular or teardrop-shaped, the shape of the fan housing cavity can be matched with the shape of the cross-flow fan, thereby making the airflow of the cross-flow fan smoother and improving the airflow efficiency of the fan.

[0047] Example 1

[0048] See also Figures 1-9 , Figure 1 It is a three-dimensional diagram of the fan 1 provided in the first embodiment of the present invention. Figure 2 yes Figure 1 A three-dimensional view of the fan 1 from another angle is shown. Figure 3 yes Figure 1 A perspective view of the fan 1 in a supported state is shown. Figure 4 yes Figure 1 A partially exploded schematic diagram of the fan 1 is shown. Figure 5 yes Figure 1 An exploded schematic diagram of the fan 1 is shown. Figure 6 yes Figure 1 A cross-sectional view of the fan 1 is shown. Figure 7 yes Figure 1 The figure shows a schematic diagram of the combination of the first gear member 31 and the second gear member 32 of the fan 1. Figure 8 yes Figure 1 The fan 1 is shown in a three-dimensional view with the magnetic base 20 in a supporting state. Figure 9 yes Figure 1 An exploded schematic diagram of the magnetic base 20 of the fan 1 is shown. An embodiment of the present invention provides a fan 1 comprising a fan body 10 and a magnetic base 20. The magnetic base 20 is used to support the fan body 10. The magnetic base 20 and the fan body 10 are magnetically attracted to each other to achieve a magnetically detachable connection with at least two different relative positions, thereby allowing the airflow direction of the fan body 10 to be adjusted, allowing the user to adjust the airflow direction according to usage requirements, facilitating use.

[0049] The fan body 10 includes a housing 11 having a fan receiving chamber 111 and a fan assembly 112 located in the fan receiving chamber 111. The fan assembly 112 includes a cross-flow fan 112a arranged along a preset direction. The housing 11 also includes an air outlet connected to the fan receiving chamber 111. The cross-flow fan 112a is used to blow air toward the air outlet 113. The magnetic base 20 is used to support the fan body 10 and has a base body 21. The magnetic base 20 also includes a first magnetic member arranged on the base body 21 or the base body 21 is a first magnetic member. The fan body 10 also includes a second magnetic member or the housing 11 is a second magnetic member. The second magnetic member is used to magnetically attract the first magnetic member so that a magnetically detachable connection is achieved between the magnetic base 20 and the fan body 10. It should be noted that the cross-flow fan 112a is also called a cross-flow fan, and its impeller is multi-bladed, long cylindrical, and has forward-facing multi-wing blades. When the impeller rotates, the airflow enters the blade grid from the opening of the impeller, passes through the inside of the impeller, and is discharged into the volute from the other side of the blade grid to form a working airflow. Since the cross-flow fan 112a has very little low interference, the wind blown out by the cross-flow fan 112a is very concentrated. In this way, it can send the wind very far under low noise conditions and can easily change the direction of the wind flow. It can be understood that when the fan 1 of this embodiment is in use, the cross-flow fan 112a blows air in the fan storage chamber 111 toward the air outlet 113 connected to the fan storage chamber 111 to achieve the purpose of cooling. At the same time, the first magnetic part and the second magnetic part are magnetically attracted to each other, so that the magnetic base 20 and the fan body 10 are magnetically connected. The first magnetic part and the second magnetic part can be detached by the magnetism of the first magnetic part and the second magnetic part, so that the fan 1 is easy to disassemble and store when it is not in use.

[0050] The fan 1 provided in the embodiment of the present invention, by arranging the first magnetic part on the magnetic base 20 and arranging the second magnetic part magnetically attracted to the first magnetic part on the fan body 10, can realize a magnetic detachable connection between the magnetic base 20 and the fan body 10, so that the air outlet range of the fan 1 is wider, meeting the user's multi-directional air outlet and cooling needs, making the user more comfortable, and also easy to disassemble and connect, so that the fan 1 is easy to carry, convenient for users to use, and better user experience. In addition, the fan assembly 112 is stored in the fan storage cavity 111, so that the fan 1 is safer and quieter when in use, and the structure of the entire fan 1 is simpler and occupies less space. The fan assembly 112 adopts the cross-flow fan 112a, which can make the air outlet speed uniform and improve human comfort.

[0051] Specifically, in this embodiment, the magnetic base 20 includes a first magnetic part provided on the base body 21, and the fan body 10 also includes a second magnetic part provided on the shell 11, and the second magnetic part is used to be magnetically connected to the first magnetic part, so that the magnetic base 20 and the fan body 10 are magnetically detachably connected. It can be understood that the first magnetic part can be embedded in the base body 21 by casting, one-piece molding or other processes, and the second magnetic part can also be embedded in the shell 11 by casting, one-piece molding or other processes. In other embodiments, the base body 21 and the shell 11 can be directly made of magnetic material or a material that can be magnetically attracted by a magnetic material, that is, the base body 21 is the first magnetic part, and the shell 11 is the second magnetic part. By arranging the first magnetic part on the base body 21 and arranging the second magnetic part magnetically connected to the first magnetic part on the shell 11, the magnetic base 20 and the fan body 10 can be relatively rotated to achieve a magnetic detachable connection in a variety of different relative positions, thereby adjusting the air outlet direction of the fan body 10, making the air outlet range of the fan 1 wider, meeting the user's multi-directional air outlet and cooling needs, making the user more comfortable, and also easy to disassemble and connect, making the fan 1 easy to carry, convenient for users to use, and better user experience. At the same time, by rotating the magnetic base 20 or the fan body 10 to achieve a variety of different relative positions of the magnetic connection between the two, the air outlet direction of the fan body 10 can be adjusted, and the operation is convenient. During the rotation process, the magnetic base 20 and the fan body 10 always maintain a magnetic connection, ensuring the safety and stability of the fan 1 during operation.

[0052] Furthermore, one of the first magnetic part and the second magnetic part is a permanent magnet, and the other of the first magnetic part and the second magnetic part is a permanent magnet or a soft magnet. It can be understood that both the first magnetic part and the second magnetic part can be permanent magnets, or one of the first magnetic part and the second magnetic part is a permanent magnet and the other is a soft magnet. A permanent magnet refers to a magnet that can retain a high remanence for a long time in an open circuit state, such as natural magnetite (magnetite), artificial magnet (aluminum nickel cobalt alloy), etc. A soft magnet refers to a magnet made of materials such as iron, and its magnetism cannot be permanently maintained, such as iron silicon alloy (silicon steel sheet). Permanent magnets and soft magnets are both common magnetic materials, and the production and processing technology is also very mature. The use of permanent magnets or soft magnets to make the first magnetic part and the second magnetic part has low production cost and is suitable for mass production. By having one of the first magnetic part and the second magnetic part be a permanent magnet and the other of the first magnetic part and the second magnetic part be a permanent magnet or a soft magnet, it is easy to produce and process, has low production cost, and is suitable for mass production.

[0053] Furthermore, the shell 11 includes a side wall structure 114 arranged around the preset direction and covering the outside of the cross-flow fan 112a, and two end plates 115 respectively connected to the two ends of the side wall structure 114, and the air outlet 113 includes a strip-shaped air outlet arranged on the side wall structure 114 and extending along the preset direction; the shell 11 also has an air inlet 116 connected to the fan storage chamber 111. By providing a side wall structure 114 that is arranged around the preset direction and covers the outside of the cross-flow fan 112a, and two end plates 115 that are respectively connected to the two ends of the side wall structure 114, the cross-flow fan 112a can be stored in the fan storage chamber 111 surrounded by the side wall structure 114 and the end plates 115, so that the air inlet and outlet of the cross-flow fan 112a are more concentrated, and the air outlet is set to a strip shape, so that the air outlet 113 can match the air outlet direction of the cross-flow fan 112a, thereby improving the air inlet and outlet efficiency of the cross-flow fan 112a.

[0054] Specifically, there are multiple strip-shaped air outlets, and the multiple air outlets 113 are arranged in a matrix along the preset direction and in a direction perpendicular to the preset direction. By providing multiple strip-shaped air outlets and arranging the multiple air outlets 113 in a matrix along the preset direction and in a direction perpendicular to the preset direction, the air output of the fan 1 can be made more uniform. At the same time, it can prevent users from accidentally inserting their fingers into the fan 1 during use, causing injuries. It can also prevent dust, hair, and other debris from entering the fan 1 and causing damage to the fan 1, thereby ensuring the safety of the fan 1 during use.

[0055] Furthermore, the air inlet 116 is in the shape of a bar extending along the preset direction, the number of the air inlet 116 is multiple, and the multiple air inlets 116 are arranged in a matrix along the preset direction and in a direction perpendicular to the preset direction. By setting the air inlet 116 in the shape of a bar extending along the preset direction, the number of the air inlet 116 is multiple, and the multiple air inlets 116 are arranged in a matrix along the preset direction and in a direction perpendicular to the preset direction, the air intake of the fan 1 can be made more uniform. At the same time, it can prevent users from accidentally inserting their fingers into the fan 1 during use, causing injuries. It can also prevent dust, hair and other debris from entering the fan 1 and causing damage to the fan 1, thereby ensuring the safety of the fan 1 during use.

[0056] Furthermore, the sidewall structure 114 has a first outer surface 114a located on the outside, and the base body 21 has a second outer surface 211 corresponding to the first outer surface 114a, and one of the first outer surface 114a and the second outer surface 211 includes an arc-shaped convex surface, and the other of the first outer surface 114a and the second outer surface 211 is an arc-shaped concave surface adapted to the arc-shaped convex surface, and the arc-shaped convex surface and the arc-shaped concave surface are magnetically connected through the first magnetic part and the second magnetic part, and the arc-shaped convex surface can rotate in the arc-shaped concave surface, so that the fan body 10 rotates relative to the magnetic base 20, thereby adjusting the air outlet direction of the fan body 10. It can be understood that in this embodiment, the first outer surface 114a can be an arc-shaped convex surface, and the second outer surface 211 is an arc-shaped concave surface adapted to the arc-shaped convex surface. Then, the base body 21 can accommodate the side wall structure 114 in the concave surface formed by the arc-shaped concave surface, so that the connection between the fan body 10 and the magnetic base 20 is more secure and not easy to fall off the magnetic base 20. In addition, the first outer surface 114a and the second outer surface 211 are set to a mutually matching arc surface structure, so that the fan body 10 can move along the arc-shaped concave surface relative to the magnetic base 20, thereby changing the relative position of the two. The operation is simple, the relative position of the two can be changed in a wide range, and the noise is low. In other embodiments, the second outer surface 211 can also be an arc-shaped convex surface, and the first outer surface 114a can be an arc-shaped concave surface adapted to the arc-shaped convex surface. By including an arcuate convex surface in one of the first outer surface 114a and the second outer surface 211, and the other of the first outer surface 114a and the second outer surface 211 being an arcuate concave surface adapted to the arcuate convex surface, the arcuate convex surface and the arcuate concave surface are magnetically connected through the first magnetic member and the second magnetic member, so that the magnetic connection between the fan body 10 and the magnetic base 20 is more secure, and the arcuate convex surface can move in the arcuate concave surface, so that the fan body 10 moves relative to the magnetic base 20, thereby adjusting the air outlet direction of the fan body 10.
