Description

Technical Field

[0001] This invention relates to the technical field of fan equipment, specifically to an automatic air-sweeping structure and a hanging screen fan. Background Technology

[0002] A screen-mounted fan is a small fan device that is placed on electronic devices (usually computer screens) to reduce the temperature of the electronic devices or to cool the user when the temperature is high. Screen-mounted fans are popular among users because they are small in size, easy to carry, and easy to assemble and disassemble.

[0003] Existing wall-mounted fans can only blow air forward. When users are using electronic devices and are sitting directly in front of the fan, the air blown out of the fan is always blowing directly at the user, which can easily cause physical discomfort. In addition, because existing wall-mounted fans can only blow air forward, the air delivery width is relatively narrow and the air delivery area is small, which also results in a poor user experience and fails to meet the user's needs. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defects of the existing screen hanging fan, which can only blow air forward, has a narrow air blowing width, and has a poor user experience, so as to provide an automatic air sweeping structure and screen hanging fan with a wide air blowing range, a large air blowing area, and a good user experience.

[0043] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0046] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0047] like Figure 1The diagram shows a preferred embodiment of the automatic air-sweeping structure of the present invention. This automatic air-sweeping structure can be applied to electrical equipment that requires air supply, such as fans and air conditioners. It can achieve automatic air sweeping, with a wide air supply range and large air supply area, resulting in good user comfort. Moreover, this automatic air-sweeping structure is compact, small in size, easy to set up, and provides a good user experience.

[0048] This automatic air-sweeping structure includes a housing 1, a wind turbine assembly, and an air-sweeping assembly.

[0049] The housing 1 serves as the carrier for the automatic air-sweeping structure and includes an air outlet 101. Specifically, the housing 1 is generally rectangular and includes an upper housing 102 and a lower housing 103. On the side facing the user, both the upper housing 102 and the lower housing 103 have openings that together form the air outlet 101, through which air can be delivered outwards. Furthermore, the upper housing 102 and the lower housing 103 can be connected by fasteners (such as screws) to form the housing 1.

[0050] like Figure 2 As shown, the lower housing 103 is generally a rectangular cover structure. Two motor mounting slots 104 are provided on the inner side of the lower housing 103 (i.e., the side of the lower housing 103 facing the upper housing 102) for mounting motors. Preferably, the two motor mounting slots 104 are symmetrically arranged with respect to the center line of the lower housing 103. Multiple air inlets 107 are provided around the motor mounting slots 104, evenly distributed around their circumference. Centrifugal duct ribs 105 are also provided on the outer side of the air inlets 107, forming impeller mounting slots 106. A gear disk mounting hole 108 is provided between the two centrifugal duct ribs 105. In this embodiment, the gear disk mounting hole 108 is located near the outer wall of the centrifugal duct rib 105 on the left side for ease of structural arrangement.

[0051] like Figure 3 As shown, the upper shell 102 is a rectangular cover structure. The inner side of the upper shell 102 (i.e. the side of the upper shell 102 facing the lower shell 103) has two centrifugal air duct upper ribs 109. The positions of the centrifugal air duct upper ribs 109 and the centrifugal air duct lower ribs 105 are vertically corresponding. An upper limit position 110 of the impeller is also provided on the inner side of the centrifugal air duct upper ribs 109. The centrifugal air duct upper ribs 109, the centrifugal air duct lower ribs 105 and the impeller upper limit position 110 together limit the position of the impeller assembly.

[0052] A fan assembly is housed within the housing 1 and is used for air intake and exhaust. The fan assembly includes a first fan 301 and a second fan 302, both of which are rotatably mounted within the housing 1. Specifically, the first fan 301 and the second fan 302 are respectively disposed within two fan mounting slots 106, and their axial directions are perpendicular to the lower housing 103. In this embodiment, both the first fan 301 and the second fan 302 are centrifugal fans. When the first fan 301 and the second fan 302 rotate rapidly, outside air enters the housing 1 through the air inlet 107, passes through the centrifugal air duct within the housing 1, and is then blown out from the air outlet 101. Figure 4 As shown, a drive gear 3011 is provided at the shaft center of the first wind turbine 301. The diameter of the drive gear 3011 is smaller than the diameter of the first wind turbine 301, and the drive gear 3011 can rotate together with the first wind turbine 301.

[0053] The further impeller assembly also includes two motors 303. In this embodiment, the motors 303 are brushless DC motors. The first impeller 301 and the second impeller 302 are each driven by a motor 303, which is disposed in the motor mounting slot 104. The first impeller 301, the second impeller 302 and the motors 303 are magnetically secured to each other in their respective mounting slots via shaft holes.

[0054] The air sweeping assembly is mounted on the housing 1. The air sweeping assembly includes several spaced air guide plates 201. The air guide plates 201 are located at the air outlet 101. The air sweeping assembly is driven by the impeller assembly and drives the air guide plates 201 to swing back and forth, thereby realizing automatic air sweeping.

[0055] In this embodiment, the air sweeping assembly includes a gear disk 202 and a linkage transmission assembly. The gear disk 202 is rotatably mounted on the housing 1 and is driven by the impeller assembly. One end of the linkage transmission assembly is hinged to the gear disk 202, and the other end is hinged to the air guide plate 201.

[0056] Furthermore, such as Figure 5 , 6As shown, the upper surface of the gear disk 202 has a connecting rod mounting shaft 2022, and the lower surface has a gear disk mounting shaft 2021. The gear disk mounting shaft 2021 mates with the gear disk mounting hole 108, allowing the gear disk 202 to be installed. After the gear disk 202 is installed on the lower housing 103, its axial direction is parallel to the axial direction of the first impeller 301. The gear disk mounting shaft 2021 and the connecting rod mounting shaft 2022 are parallel to each other, with the gear disk mounting shaft 2021 positioned along the axial direction of the gear disk 202, while the connecting rod mounting shaft 2022 is eccentrically positioned relative to the axial direction of the gear disk 202. Specifically, the gear disk 202 meshes with the driving gear 3011, making the gear disk 202 a driven gear.

[0057] Furthermore, the air sweeping assembly also includes an air guide plate bracket 203, which is disposed within the housing 1, and the air guide plate 201 is rotatably mounted on the air guide plate bracket 203. Figure 7 As shown, the air guide plate bracket 203 is a rectangular frame structure, with its plane perpendicular to the inner side of the lower housing 103. The length direction of the air guide plate bracket 203 is parallel to the length direction of the lower housing 103. The upper long side of the air guide plate bracket 203 has multiple air guide rib plate mounting grooves 2031, one side of which has a notch and a certain degree of elasticity. The lower long side of the air guide plate bracket 203 has multiple air guide rib plate lower mounting holes 2032, and the upper and lower positions of the air guide rib plate mounting grooves 2031 and the lower air guide rib plate lower mounting holes 2032 correspond to each other. In this embodiment, there are 8 air guide rib plate mounting grooves 2031 and 8 air guide rib plate lower mounting holes 2032. Furthermore, to improve structural strength, multiple spaced reinforcing ribs 2033 are provided between the upper and lower long sides of the air guide plate bracket 203. In this embodiment, there are 7 reinforcing ribs 2033.

[0058] Furthermore, the air guide plate bracket 203 is connected to the housing 1 via a plug-in mechanism. Specifically, the plug-in mechanism includes a plug-in groove 401 and a plug-in retainer 402, which can be plugged into each other. The plug-in groove 401 is formed on both side walls of the air outlet 101, and the plug-in retainer 402 is disposed on both sides of the air guide plate bracket 203. In this embodiment, since the air outlet 101 is formed by the upper housing 102 and the lower housing 103, a portion of the plug-in groove 401 is formed on the upper housing 102, and the other portion is formed on the lower housing 103. During installation, the plug-in retainer 402 of the air guide plate bracket 203 can be inserted into the plug-in groove 401 of the lower housing 103 first, and then the plug-in groove 401 of the upper housing 102 can be aligned with the plug-in retainer 402 to achieve the installation connection of the upper housing 102, the air guide plate bracket 203, and the lower housing 103. This plug-in mechanism has a simple structure, is easy to operate, and is convenient to assemble and disassemble.

[0059] Furthermore, the linkage drive assembly includes a connecting rod 204 and a guide rod 205. One end of the connecting rod 204 is eccentrically hinged to the gear disk 202, and the other end is hinged to the guide rod 205. The guide rod 205 is also hinged to the guide plate 201. The guide rod 205 and the guide plate bracket 203 are arranged parallel to each other in the length direction. Specifically, as shown... Figure 8 As shown, the connecting rod 204 is a rod-shaped structure, with a first mounting hole 2041 and a second mounting hole 2042 at each end. The first mounting hole 2041 cooperates with the connecting rod mounting shaft 2022 to achieve the hinge connection between the connecting rod 204 and the gear disk 202, while the second mounting hole 2042 is structurally connected to the air guide plate 201.

[0060] Furthermore, such as Figure 9 As shown, the air guide rod 205 is a rod-shaped structure with multiple air guide rod mounting holes 2051 formed on it. The number of air guide rod mounting holes 2051 is greater than or equal to the number of air guide plates 201. In this embodiment, the number of air guide rod mounting holes 2051 is 8. The length direction of the air guide rod 205 is parallel to the length direction of the air guide plate bracket 203.

[0061] Furthermore, such as Figure 10 As shown, the air guide plate 201 includes an air guide rib plate 2011 and an air guide extension rod 2012. One end of the air guide extension rod 2012 is connected to the upper end of the air guide rib plate 2011. The air guide rib plate 2011 and the air guide extension rod 2012 are parallel and extend in opposite directions. The upper and lower ends of the air guide rib plate 2011 are both hinged to the air guide plate bracket 203. The end of the air guide extension rod 2012 away from the air guide rib plate 2011 is hinged to the air guide rod 205.

[0062] Specifically, the upper and lower ends of the air guide plate 2011 are respectively equipped with an upper air guide plate mounting shaft 2013 and a lower air guide plate mounting shaft 2014, which are coaxially arranged. The upper air guide plate mounting shaft 2013 is adapted to be inserted into the upper air guide plate mounting groove 2031, while the lower air guide plate mounting shaft 2014 is inserted into the lower air guide plate mounting hole 2032, thereby achieving the hinge connection between the air guide plate 201 and the air guide plate bracket 203. During installation, the lower air guide plate mounting shaft 2014 is first inserted into the lower air guide plate mounting hole 2032, and then the upper air guide plate mounting shaft 2013 is inserted into the upper air guide plate mounting groove 2031, achieving the hinge connection between the air guide plate 201 and the air guide plate bracket 203. After installation, a portion of the air guide plate 2011 extends out of the air outlet 101 to enhance the air guiding effect.

[0063] Specifically, the air guide extension rod 2012 extends from the mounting shaft 2013 on the air guide plate. The end of the air guide extension rod 2012 away from the mounting shaft 2013 on the air guide plate has an air guide extension rod mounting shaft 2015. The air guide extension rod mounting shaft 2015 extends upward and can be installed with the air guide extension rod mounting hole 2051, thereby realizing the hinge connection between the air guide plate 201 and the air guide rod 205.

[0064] Furthermore, the end of the connecting rod 204 that is hinged to the air guide rod 205 is also hinged to the air guide extension rod 2012 of one of the air guide plates 201. Specifically, the air guide extension rod mounting shaft 2015 on one of the air guide plates 201 can be simultaneously hinged to the second mounting hole 2042 and the air guide extension rod mounting hole 2051. In this embodiment, there are eight air guide plates 201, and the air guide extension rod mounting shaft 2015 on the fourth air guide plate 201 from the left is simultaneously hinged to the second mounting hole 2042 and the air guide extension rod mounting hole 2051.

[0065] This embodiment also provides a hanging screen fan, including the automatic air-sweeping structure provided in this embodiment. Of course, the hanging screen fan in this embodiment also includes other structures and components that are present in existing hanging screen fans. Since this invention does not involve these structures and components, they will not be described in detail here.

[0066] This type of hanging screen fan can automatically sweep the air, so that the air does not blow straight forward. Instead, it can automatically sweep the air by the reciprocating oscillation of the air guide plate, thereby expanding the air delivery range, increasing the air delivery area, and improving the user's comfort. Moreover, this automatic sweeping structure is compact, small in size, easy to set up, and provides a good user experience.

[0067] like Figure 11-13 As shown in the accompanying drawings, to further understand the automatic air-sweeping structure of this embodiment, the working process of the automatic air-sweeping structure of this embodiment will be described below with reference to the accompanying drawings:

[0068] In this embodiment, the hanging screen fan is placed horizontally, so the automatic air sweeping structure can perform automatic air sweeping in the horizontal direction, and the initial position of the air guide plate 201 is set to forward, that is, towards the user side.

[0069] When the hanging screen fan is powered on and started, the motor 303 drives the first impeller 301 and the second impeller 302 to rotate. In this embodiment, taking the first impeller 301 and the second impeller 302 rotating counterclockwise as an example, outside air enters the centrifugal air duct through the air inlet 107 and is blown out from the air outlet 101 under the guidance of the centrifugal air duct. At the same time, the drive gear 3011 rotates counterclockwise with the first impeller 301. The drive gear 3011 will drive the gear disk 202 to rotate clockwise. Since the connecting rod 204 is eccentrically hinged to the gear disk 202, the connecting rod 204 and the gear disk... One end of the gear 202 hinged together will rotate clockwise around the axis of the gear disk 202. Due to the limitation of the connecting structure, the end of the connecting rod 204 hinged together with the guide rod 205 will move to the right, thereby driving the guide rod 205 to move to the right. The end of the guide rod 2012 hinged together with the guide rod 205 will also move to the right. The guide rib plate 2011 will rotate around its connecting axis with the guide plate bracket 203. The guide rib plate 2011 extending out of the air outlet will swing to the left. When the end of the connecting rod 204 hinged together with the gear disk 202 moves to the left side of the axis of the gear disk 202 (e.g. Figure 11 (As shown in the image), the air guide rib 2011 reaches its left limit position, and the wind blows out to the left.

[0070] The drive gear 3011 continues to drive the gear disk 202 to rotate clockwise. When the end of the connecting rod 204 that is hinged to the gear disk 202 moves to the rear of the axis of the gear disk 202 (e.g.) Figure 12 (As shown in the image), the air guide rib 2011 faces forward, and the air blows forward;

[0071] The driving gear 3011 continues to drive the gear disk 202 to rotate clockwise. When the end of the connecting rod 204 that is hinged to the gear disk 202 moves to the right side of the axis of the gear disk 202 (e.g.) Figure 13 (As shown in the image), the air guide rib 2011 reaches its right limit position, and the wind blows out to the right.

[0072] This process repeats, causing the air guide plate 201 to swing back and forth horizontally (the swing direction is as follows). Figure 11-13 (As shown by the middle arrow), thus achieving automatic horizontal air sweeping of the hanging screen fan.

[0073] It should be noted that the oscillation speed of the air guide plate 201 is directly proportional to the rotation speed of the first impeller 301. The higher the wind speed, the faster the air guide speed, and the better the user's air blowing experience. Moreover, the oscillation direction of the air guide plate 201 is related to the setting posture of the hanging screen fan. For example, when the hanging screen fan in this embodiment is placed vertically, the oscillation direction of the air guide plate 201 becomes a vertical direction for automatic air sweeping.

[0074] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
