Technical Field

[0001] This application relates to the field of fan technology, and more specifically, to a desktop tower fan assembly and a desktop tower fan. Background Technology

[0002] When the tower fan is running, the fan wheel rotates, driving the airflow through the air outlet grille on the fan cylinder to blow towards the user. However, since the airflow inside the fan cylinder blows towards the air outlet grille along the annular air duct, and the air outlet grille is located on the outside of the annular air duct, the airflow on the outside of the annular air duct can blow towards the user through the air outlet grille, while the airflow on the inside of the annular air duct cannot blow towards the user through the air outlet grille. This results in a large airflow loss inside the fan cylinder and poor airflow effect, so it is urgent to improve. Utility Model Content

[0003] Therefore, it is necessary to provide a desktop tower fan assembly to address the above problems, which aims to enable the airflow on both the outer and inner sides of the annular air duct inside the fan cylinder to be blown towards the user through the air outlet grille, so as to effectively reduce the airflow loss inside the fan cylinder and enhance the blowing effect.

Detailed Implementation

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0030] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0031] This application provides a desktop tower fan assembly, which has multiple air guides arranged circumferentially along the fan cylinder on the inner side of the air outlet grille. Each air guide is curved toward the volute tongue and arranged in an arc shape, so that the multiple air guides can guide the airflow on the outer and inner sides of the annular air duct inside the fan cylinder to the air outlet grille and blow it out, thereby effectively reducing the airflow loss in the fan cylinder and enhancing the blowing effect.

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0033] Please see Figures 1 to 3 This application provides a desktop tower fan assembly 100, which includes: a fan cylinder 10, a fan wheel 20, a volute 30, a control component 40, and an air outlet grille 50.

[0034] The fan cylinder 10 provides installation space for other components, such as the fan wheel 20, volute 30, control unit 40, and air outlet grille 50, which will be introduced below. The fan cylinder 10 has many shapes, such as cylindrical, square, or other shapes, and is not specifically limited here.

[0035] Obviously, the fan cylinder 10 also has an air inlet grille 11. The air inlet grille 11 and the air outlet grille 50 are arranged circumferentially around the fan cylinder 10. The air inlet grille 11 and the air outlet grille 50 can be formed directly through corresponding positions on the outer peripheral wall of the fan cylinder 10. Alternatively, the air inlet grille 11 and the air outlet grille 50 can be independent grille ventilation components. In this case, the grille ventilation component and the fan cylinder 10 can be fixed by other fixed connection methods such as bonding or ultrasonic welding. The grille ventilation structure and the fan cylinder 10 can also be fixed by other detachable connection methods such as snap-fit ​​131 connection, magnetic connection, or threaded connection. In this embodiment, the air inlet grille 11 is formed through corresponding positions on the outer peripheral wall of the fan cylinder 10, thus making the air inlet grille 11 and the fan cylinder 10 integrally formed, thereby enhancing the stability of the connection between the air inlet grille 11 and the fan cylinder 10.

[0036] The fan wheel 20 is located inside the fan cylinder 10 and is eccentrically positioned, meaning its axis is parallel to and spaced apart from the axis of the fan cylinder 10. This facilitates the airflow from the inlet grille 11 to the outlet grille 50 by the rotation of the fan wheel 20. In other embodiments, the fan wheel 20 may also be concentrically positioned with the fan cylinder 10, meaning its axis coincides with the axis of the fan cylinder 10. Alternatively, the fan wheel 20 may be inclined relative to the axis of the fan cylinder 10, meaning its axis intersects the axis of the fan cylinder 10 at a certain angle.

[0037] The volute tongue 30 is a tongue-shaped structure located at the air outlet grille 50 of the fan cylinder 10. It is mainly used to prevent gas from circulating inside the fan cylinder 10. Specifically, the volute tongue 30 is located on the inner circumferential wall of the fan cylinder 10, and the volute tongue 30 is integrally formed with the fan cylinder 10. This can enhance the structural stability of the connection between the volute tongue 30 and the fan cylinder 10.

[0038] The control component 40 is integrated within the volute 30. The outer peripheral wall of the fan cylinder 10 has a mounting port 12 that communicates with the interior of the volute 30. A touch panel 13 is sealed at the mounting port 12, and the touch panel 13 abuts against the control component 40. This allows the user to control the desktop tower fan 1000 by pressing the touch position on the touch panel 13, such as starting or stopping the desktop tower fan 1000, switching the speed of the desktop tower fan 1000, and setting a timer for the desktop tower fan 1000's operation. For details, please refer to [link to relevant documentation]. Figures 1 to 3 The touch panel 13 is provided with a buckle 131, and the inner peripheral wall of the fan cylinder 10 is provided with a buckling protrusion 14 that cooperates with the buckle 131 at the position adjacent to the mounting port 12, so as to facilitate the disassembly and assembly of the touch panel 13, thereby facilitating the inspection, cleaning or replacement of the touch panel 13.

[0039] An air outlet grille 50 is disposed on the fan cylinder 10, and the air outlet grille 50 is located to the side of the volute tongue 30 in the circumferential direction of the fan cylinder 10. In this embodiment, please refer to... Figures 2 to 4 The air outlet grille 50 has fasteners 501 on both sides of the fan cylinder 10 in the circumferential direction. The inner circumferential wall of the fan cylinder 10 has two fastening grooves 15, each of which engages with the corresponding fastener 501 to facilitate the installation and removal of the air outlet grille 50, thereby simplifying maintenance, cleaning, or replacement. Furthermore, one of the fastening grooves 15 is formed through a portion of the volute tongue 30, thus facilitating its formation.

[0040] Further, please refer to Figure 1 and Figure 4 The diameter of the air outlet grille 50 gradually expands from its inner side to its outer side, which allows the airflow to be diffused after passing through the air outlet grille 50, thereby increasing the air blowing area of ​​the air outlet grille 50.

[0041] Please see Figure 2 and Figure 4The inner side of the air outlet grille 50 is provided with multiple air guides 51 arranged at intervals along the circumference of the fan cylinder 10. In this article, "multiple" refers to two or more. Each air guide 51 is arc-shaped, and the outer convex side of each air guide 51 is facing the volute tongue 30.

[0042] In this embodiment, multiple guide members 51 are evenly spaced along the circumference of the fan cylinder 10, meaning the distance between adjacent guide members 51 is equal. This allows for the uniform guidance of airflow within the annular duct of the fan cylinder 10, resulting in more consistent airflow intensity at various locations of the air outlet grille 50. In other embodiments, the multiple guide members 51 may be non-equally spaced along the circumference of the fan cylinder 10. For example, the distance between adjacent guide members 51 may gradually increase from the air outlet grille 50 to the volute tongue 30, or the distance may gradually decrease from the air outlet grille 50 to the volute tongue 30.

[0043] Furthermore, in this embodiment, the number of guide elements 51 is set to four. This arrangement optimizes the airflow guiding effect of the guide elements 51, that is, maximizes the guidance of airflow from the outer and inner sides of the annular air duct inside the fan cylinder 10 to the air outlet grille 50. In other embodiments, the number of guide elements 51 can also be set to two, three, five, six, or other values.

[0044] Specifically, please refer to Figure 1 and Figure 5 The air outlet grille 50 has multiple axial grilles 52, each extending along the axial direction of the fan cylinder 10. These axial grilles 52 are evenly spaced along the circumference of the fan cylinder 10. Each guide element 51 also extends circumferentially along the fan cylinder 10. The inner side of each axial grille 52 is smoothly connected to its corresponding guide element 51, allowing the airflow to flow directly through the axial grilles 52 and be blown out after being guided by the guide elements 51. Additionally, the air outlet grille 50 also has a circumferential grille 53, which connects to the multiple axial grilles 52 to enhance the stability of the air outlet grille 50.

[0045] Through the above technical solution, when the airflow is driven from the air inlet grille 11 to the air outlet grille 50 by the rotation of the fan wheel 20, firstly, the airflow from the external environment flows from the air inlet grille 11 into the annular air duct inside the fan cylinder 10 by the rotation of the fan wheel 20. Then, the airflow on the outer and inner sides of the annular air duct is thrown along the tangential direction of the outer convex side of the multiple guide members 51 to the space between two adjacent guide members 51 by the rotation of the fan wheel 20. Finally, the airflow between the two adjacent guide members 51 is blown out along the air outlet grille 50. This arrangement allows the multiple guide members 51 to guide the airflow on the outer and inner sides of the annular air duct inside the fan cylinder 10 to the air outlet grille 50 and blown out, thereby effectively reducing the airflow loss inside the fan cylinder 10 and enhancing the blowing effect. Furthermore, the integration of the control unit 40 into the volute 30 allows the control unit 40 and the volute 30 to utilize the same space within the fan cylinder 10 without occupying additional space, which facilitates the integrated design of the desktop tower fan assembly 100.

[0046] To enhance the airflow guiding effect of the multiple guide members 51, please refer to Figure 2. In one embodiment of this application, the length between the end of the multiple guide members 51 that is away from the air outlet grille 50 and the end that is close to the air outlet grille 50 gradually decreases from the air outlet grille 50 to the volute tongue 30. This arrangement causes the distance between the multiple guide members 51 and the outer peripheral wall of the fan wheel 20 to gradually decrease from the air outlet grille 50 to the volute tongue 30, thereby making the airflow in the annular air duct inside the fan cylinder 10 more concentrated and flowing faster to the space between two adjacent guide members 51, thus enhancing the airflow guiding effect of the guide members 51.

[0047] There are many types of the aforementioned cochlear tongue 30; please refer to [link / reference]. Figure 2 and Figure 3 In one embodiment of this application, the volute tongue 30 includes a first guide section 31 and a second guide section 32 connected at an acute angle. The first guide section 31 and the second guide section 32 are located far apart on the inner peripheral wall of the fan cylinder 10. The first guide section 31 is arc-shaped, and the concave side of the first guide section 31 faces the convex side of the guide member 51 closest to the volute tongue 30 among the multiple guide members 51. With this arrangement, the rotation of the fan wheel 20 can drive part of the airflow in the annular air duct to be thrown between the guide member 51 near the volute tongue 30 and the first guide section 31, and then flow out from the air outlet grille 50 through the guidance of the convex side of the guide member 51 and the concave side of the first guide section 31. This can further reduce the airflow loss and thus further enhance the blowing effect.

[0048] Specifically, both the first guide section 31 and the second guide section 32 are integrally formed with the fan cylinder 10, which enhances the structural strength of the volute tongue 30. Furthermore, the second guide section 32 is arranged in a gentle arc shape, which can smoothly guide the airflow that is not blown out by the air outlet grille 50 to the inner peripheral wall of the fan cylinder 10 and diffuse it, so as to avoid turbulence and backflow within the fan cylinder 10.

[0049] Further, please refer to Figure 2 and Figure 3 The volute tongue 30 also includes a bent section 33 with a "7"-shaped cross-section, where the cross-section refers to the section along the radial direction of the fan cylinder 10. The bent section 33 is connected to the end of the first guide section 31 away from the second guide section 32 at an acute angle, and the end of the bent section 33 away from the first guide section 31 is connected to the inner peripheral wall of the fan cylinder 10, thus enhancing the structural strength of the volute tongue 30. In addition, the retaining groove on the volute tongue 30 is provided on the part of the bent section 33 away from the first guide section 31, making the retaining groove easy to set.

[0050] As an example and not a limitation, the angle between the first guide section 31 and the second guide section 32, and the angle between the first guide section 31 and the bending section 33, can be any other acute angle value such as 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees, 60 degrees, 65 degrees, 70 degrees, or 75 degrees. Furthermore, the angle between the first guide section 31 and the second guide section can be greater than, equal to, or less than the angle between the first guide section 31 and the bending section 33.

[0051] Considering that if the curvature of the first guide section 31 is too large, turbulence and backflow may easily form at the first guide section 31, affecting the guiding effect of the first guide section 31, please refer to [the relevant documentation]. Figure 2 and Figure 3 In one embodiment of this application, the curvature of the guide member 51 is greater than the curvature of the first guide section 31. This configuration can effectively prevent the formation of turbulence and backflow at the first guide section 31 when the first guide section 31 guides the airflow, thereby ensuring the guiding effect of the first guide section 31.

[0052] Considering that if the ends of the first guide section 31 and the second guide section 32 are directly connected, a whistling sound is easily generated when the airflow blows towards the connection point of the first guide section 31 and the second guide section 32. Therefore, in order to avoid whistling sound at the connection point of the first guide section 31 and the second guide section 32, please refer to [link / reference needed]. Figure 2 and Figure 3In one embodiment of this application, the volute tongue 30 further includes a straight connecting section 34, the two ends of which are connected to the first guide section 31 and the second guide section 32 at obtuse angles. With this configuration, the connecting section 34 can smoothly divert the airflow blowing towards the connection between the first guide section 31 and the second guide section 32, thereby effectively preventing the generation of whistling sound at the connection between the first guide section 31 and the second guide section 32.

[0053] In other embodiments, the volute tongue 30 may also be configured to include only the first guide section 31 and the second guide section 32.

[0054] There are many ways to integrate the aforementioned control element 40 into the volute tongue 30; please refer to [link / reference]. Figure 2 and Figure 3 In one embodiment of this application, the control member 40 is inserted between the volute tongue 30 and the inner peripheral wall of the fan cylinder 10 along the axial direction of the fan cylinder 10. With this arrangement, the control member 40 can be inserted between the volute tongue 30 and the inner peripheral wall of the fan cylinder 10 or pulled out from between the volute tongue 30 and the inner peripheral wall of the fan cylinder 10 along the axial direction of the fan cylinder 10, making it convenient to install and remove the control member 40.

[0055] Specifically, please refer to Figure 2 and Figure 3 The control component 40 is inserted along the axial direction of the fan cylinder 10 into the insertion space 301 enclosed by the second guide section 32 away from the first guide section 31, the bent section 33 away from the first guide section 31, and the inner peripheral wall of the fan cylinder 10. In this way, the second guide section 32 and the bent section 33 can jointly support the limiting control component 40, so that the insertion stability of the control component 40 is strong.

[0056] Further, please refer to Figure 2 , Figure 3 as well as Figure 5 The volute tongue 30 is provided with a limiting plate 302 on one side of the fan cylinder 10 along the axial direction. The control component 40 is inserted between the volute tongue 30 and the inner peripheral wall of the fan cylinder 10 along the axial direction and then abuts against the limiting plate 302. This makes it easy to determine whether the control component 40 is inserted in place.

[0057] In other embodiments, the volute tongue 30 may have a placement port on the circumferential side of the fan cylinder 10. The control component 40 is placed into the volute tongue 30 through the placement port and then magnetically fixed to the volute tongue 30. This also achieves the integrated setting of the control component 40 and the volute tongue 30.

[0058] Considering that the desktop tower fan 1000 also includes a driver unit 60 and a power supply unit 70, for convenient electrical connection of the driver unit 60 and the power supply unit 70, please refer to [link / reference needed]. Figure 2 , Figure 3 as well as Figure 6In one embodiment of this application, the two ends of the fan cylinder 10 are used to insert a drive component 60 and a power supply component 70. The drive component 60 and the power supply component 70 are detachably rotatably connected to the two ends of the fan wheel 20 along the axial direction. The detachable rotatable connection can be achieved by the cooperation of a bushing and a rotating shaft, or by the cooperation of a fixed shaft and a shaft hole, or by other means, which are not specifically limited here. The drive component 60 is used to drive the fan wheel 20 to rotate. The power supply component 70 is electrically connected to the drive component 60. The control component 40 and the volute tongue 30 surround to form a wire passage space 303 extending along the axial direction of the fan cylinder 10. With this configuration, one end of the wire is first electrically connected to the power supply component 70, and then the other end of the wire is passed through the wire passage space 303 and electrically connected to the drive component 60, so that the power supply component 70 and the drive component 60 can be electrically connected. This makes the electrical connection between the power supply component 70 and the drive component 60 convenient. Furthermore, the volute 30, control unit 40, and wiring space 303 can be integrated into the same place within the fan barrel 10 without occupying additional space, which is beneficial for the integrated setup of the desktop tower fan assembly 100.

[0059] Specifically, please refer to Figure 3 , Figure 5 as well as Figure 6 The limiting plate 302 is located on the side of the volute tongue 30 near the power supply component 70. The limiting plate 302 is provided with a wire passage opening 3021. In this way, one end of the wire is first electrically connected to the power supply component 70, and then the other end of the wire is passed through the wire passage opening 3021 and electrically connected to the control component 40, so that the control component 40 and the power supply component 70 can be electrically connected, making the electrical connection between the control component 40 and the power supply component 70 convenient.

[0060] Furthermore, the drive component 60 and the power supply component 70 abut against the two ends of the air outlet grille 50 in the axial direction of the fan cylinder 10, thereby allowing the air outlet grille 50 to limit the movement of the drive component 60 and the power supply component 70, making it easier to determine whether the drive component 60 and the power supply component 70 are properly inserted. In addition, the drive component 60 and the power supply component 70 are also fixed to the two ends of the volute tongue 30 in the axial direction of the fan cylinder 10 by bolts, thus enhancing the stability of the drive component 60 and the power supply component 70.

[0061] To enhance heat dissipation of the wires within the 303 cable pass-through space, please refer to [link / reference needed]. Figure 2 and Figure 3 In one embodiment of this application, the wire passage space 303 is located on the side of the volute tongue 30 near the guide member 51. With this arrangement, the heat in the wire passage space 303 can be transferred to the side of the volute tongue 30 near the guide member 51, so that the airflow between the guide member 51 near the volute tongue 30 and the side of the volute tongue 30 near the guide member 51 can carry away the heat transferred to the side of the volute tongue 30 near the guide member 51, thereby enhancing the heat dissipation effect of the wire in the wire passage space 303.

[0062] Please see Figure 1 and Figure 2 In one embodiment of this application, the desktop tower fan assembly 100 further includes a volute 80, which is disposed on the inner peripheral wall of the fan cylinder 10, and the air outlet grille 50 is located between the volute 80 and the volute tongue 30; among the plurality of guide members 51, the guide members 51 near the volute 80 are staggered with the volute 80 in the circumferential direction of the fan cylinder 10. This arrangement allows the guide members 51 near the volute 80 to guide the airflow between the volute 80 and the fan wheel 20 to the air outlet grille 50 before the airflow leaves the volute 80, thereby further reducing wind loss and enhancing the blowing effect.

[0063] Specifically, please refer to Figure 1 and Figure 2 The volute 80 extends circumferentially along the fan cylinder 10 and is arranged in an arc shape. The inner circumferential wall of the fan cylinder 10 is adjacent to the air inlet grille 11 and is provided with an inclined guide plate 16 on the side near the volute 80. One end of the volute 80 in the circumferential direction abuts against the end of the guide plate 16 away from the air outlet grille 50, and the other end of the volute 80 in the circumferential direction abuts against the side of the air outlet grille 50 in the circumferential direction of the fan cylinder 10. In this way, the airflow flows into the fan cylinder 10 through the air outlet grille 50 and is directly guided to the air outlet grille 50 through the guide plate 16 and the volute 80, so as to minimize air loss.

[0064] Further, please refer to Figure 1 and Figure 2 The outer peripheral wall of the volute 80 has circumferentially extending plates 81 at both ends of the fan cylinder 10. The outer side of each plate 81 has an insertion notch 811, and the inner peripheral wall of the fan cylinder 10 has an axially extending insertion protrusion 17. The insertion protrusion 17 engages with the insertion notch 811, thus facilitating the installation of the volute 80. Obviously, one or more insertion notches 811 and insertion protrusions 17 can be used, and no specific limitation is made here. Furthermore, the volute 80 can be installed using either a fixed connection or a detachable connection as described in the above embodiments, and no specific limitation is made here.

[0065] Please see Figure 7 This application also provides a desktop tower fan 1000, which includes the desktop tower fan assembly 100 as described above. The specific structure of the desktop tower fan assembly 100 is as described in the above embodiments. Since the desktop tower fan 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0066] It should be noted that the fan tube 10 can be placed horizontally or vertically. The following description will use the horizontal and vertical placement of the fan tube 10 as examples.
