Description

Technical Field

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

[0002] Tower fans are based on the principles of aerodynamics, creating a three-dimensional air exchange system between indoor and outdoor air. Tower fans typically "throw" air out through a cross-flow fan, forming an airflow. In other words, the rotation of the fan wheel creates wind pressure, generating centrifugal force, which is then transmitted out through the internal air guide wall.

[0003] Typically, tower fans consist of a base and a fan cylinder mounted on top of the base. The fan cylinder contains a fan wheel, and the base integrates a drive module and a power module electrically connected to the drive module. The output shaft of the drive module is coaxially connected to the fan wheel to drive the fan wheel to rotate. With this configuration, the heat generated by the drive module and the power module is concentrated in the base, resulting in poor heat dissipation of the drive module and the power module, which urgently needs improvement.

[0014] In one embodiment, the inner peripheral wall of the fan cylinder is provided with a partition, and the partition and the inner peripheral wall of the fan cylinder surround to form a wire passage extending along the axial direction of the fan cylinder. The drive module is provided with a drive wire passage port communicating with the wire passage channel, and the power module is provided with a power wire passage port communicating with the wire passage channel.

[0033] 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.

[0034] 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.

[0035] This application provides a desktop high-speed tower fan, which separates the drive module and power module at both ends of the fan barrel axis, rather than the traditional layout where the drive module and power module are integrated. The heat from the drive module and the power module is dispersed at both ends of the fan barrel axis, so that the heat from the drive module will not spread to the power module, and similarly, the heat from the power module will not spread to the drive module, thereby enhancing the heat dissipation effect of the drive module and the power module.

[0036] 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.

[0037] Please see Figure 1 and Figure 2 This application provides a desktop high-speed tower fan 1000, which includes: a fan barrel 100, a fan wheel 200, a drive module 300, and a power module 400.

[0038] The fan cylinder 100 is a cylindrical shape with open ends. The fan cylinder 100 provides installation space for other components such as the fan wheel 200, drive module 300, and power module 400. The fan cylinder 100 has many shapes, such as cylindrical, square, or other shapes. No specific limitation is made here.

[0039] The fan cylinder 100 has an air inlet area 101 and an air outlet area 102 arranged at intervals along its circumference. The air inlet area 101 and the air outlet area 102 can be formed directly through corresponding positions on the outer peripheral wall of the fan cylinder 100. Alternatively, the air inlet area 101 and the air outlet area 102 can be formed by a grille-type ventilation structure. In this case, the grille-type ventilation structure and the fan cylinder 100 can be fixed by other fixed connection methods such as bonding or ultrasonic welding. Alternatively, the grille-type ventilation structure and the fan cylinder 100 can be fixed by other detachable connection methods such as snap-fit ​​connection, magnetic connection, or threaded connection.

[0040] The fan wheel 200 is located inside the fan cylinder 100. There are many ways to set the fan wheel 200. The fan wheel 200 can be set concentrically with the fan cylinder 100, that is, the axis of the fan wheel 200 coincides with the axis of the fan cylinder 100. The fan wheel 200 can also be set eccentrically, that is, the axis of the fan wheel 200 is parallel to the axis of the fan cylinder 100 and spaced apart. The fan wheel 200 can also be set at an angle relative to the axis of the fan cylinder 100, that is, the axis of the fan wheel 200 intersects the axis of the fan cylinder 100 at a certain angle. No specific limitation is made here.

[0041] The drive module 300 and the power module 400 are respectively located at both ends of the fan cylinder 100 along the axial direction, and the drive module 300 and the power module 400 are electrically connected. The drive module 300 and the power module 400 are rotatably connected to the two ends of the fan wheel 200 along the axial direction. The drive module 300 is used to drive the fan wheel 200 to rotate. For details, please refer to [link to relevant documentation]. Figure 2 and Figure 3 A rotating sleeve 201 is fixed at one axial end of the fan wheel 200, and a rotating shaft 202 is provided at the other axial end of the fan wheel 200. The output shaft 301 of the drive module 300 is rotatably inserted into the rotating sleeve 201. The power module 400 is provided with a rotating hole 401, and the rotating shaft 202 is rotatably inserted into the rotating hole 401. This arrangement makes the rotational docking of the drive module 300 and the power module 400 with the fan wheel 200 detachable, thereby facilitating the assembly and disassembly of the drive module 300, the power module 400, and the fan wheel 200.

[0042] There are many types of power modules 400. Power modules 400 can be constructed using rechargeable batteries such as lithium-ion batteries, nickel-metal hydride batteries, and lithium-air batteries. They can also be constructed using non-rechargeable batteries such as lithium-air batteries and zinc-air batteries. Furthermore, power modules 400 can incorporate both rechargeable and non-rechargeable batteries; no specific limitations are made here. Obviously, regardless of the type of power module 400 used, multiple power modules 400 can be used. In this case, the power modules 400 are detachably connected to the fan barrel 100. This allows for the continued supply of power to the drive module 300 simply by replacing the power module 400 when the battery is depleted and cannot be recharged.

[0043] Through the above technical solution, the drive module 300 and the power module 400 are separately located at opposite ends of the fan barrel 100 along the axial direction, instead of being integrated into the same space as in the traditional method. This dispersed arrangement prevents heat from spreading between the drive module 300 and the power module 400, thus distributing the heat between them along the axial direction of the fan barrel 100 and enhancing their heat dissipation. Furthermore, when the drive module 300 drives the fan wheel 200 to rotate, a portion of the airflow generated by the rotation of the fan wheel 200 blows towards the side of the drive module 300 and the power module 400 that are close together, as well as the assembly gap between the drive module 300 and the fan barrel 100 and the assembly gap between the power module 400 and the fan barrel 100, effectively cooling the drive module 300 and the power module 400.

[0044] There are many ways to disassemble and assemble the aforementioned driver module 300 and power module 400. Please refer to [link / reference]. Figures 1 to 3 In one embodiment of this application, the drive module 300 and the power module 400 are inserted into the two ends of the fan barrel 100 along the axial direction. With this configuration, the drive module 300 or the power module 400 can be installed by inserting it into the end of the fan barrel 100. Similarly, the drive module 300 or the power module 400 can be disassembled by removing it from the end of the fan barrel 100. This makes it convenient to install and remove the drive module 300 and the power module 400, thereby facilitating the maintenance or replacement of the drive module 300 and the power module 400.

[0045] Furthermore, the insertion and connection of the drive module 300 and the fan barrel 100, as well as the insertion and connection of the power module 400 and the fan barrel 100, are all interference fits, which can enhance the stability of the drive module 300 and the power module 400.

[0046] Specifically, the drive module 300 is inserted into one axial end of the fan barrel 100, with its outer peripheral wall fitting into the inner peripheral wall of the fan barrel 100. The power module 400 is inserted into the other axial end of the fan barrel 100, with its outer peripheral wall fitting into the inner peripheral wall of the fan barrel 100. This arrangement allows both the drive module 300 and the power module 400 to be located within the fan barrel 100, thereby reducing the size of the desktop high-speed tower fan 1000 and facilitating its integrated design. In other embodiments, both the drive module 300 and the power module 400 may be partially inserted into the end of the fan barrel 100, with the remaining portion exposed. This allows both the drive module 300 and the power module 400 to be partially exposed to the external environment, improving their heat dissipation.

[0047] Furthermore, in other embodiments, the drive module 300 and the fan barrel 100, as well as the power module 400 and the fan barrel 100, can also be fixed together by other detachable connection methods such as magnetic connection or snap-fit ​​connection. The drive module 300 and the fan barrel 100, as well as the power module 400 and the fan barrel 100, can also be fixed together by other fixed connection methods such as bonding or ultrasonic welding.

[0048] Further, please refer to Figure 4 and Figure 5 The inner peripheral wall of the fan cylinder 100 is provided with a first guide bar 103 and a second guide bar 104 at both ends along the axial direction of the fan cylinder 100. Both extend along the axial direction of the fan cylinder 100. Please refer to [link to relevant documentation]. Figure 6 and Figure 7 The outer peripheral wall of the drive module 300 is provided with a first guide channel 302 that engages with the first guide strip 103. Please refer to [link / reference]. Figure 8 and Figure 9 The outer peripheral wall of the power module 400 is provided with a second guide channel 402 that engages with the second guide strip 104. This serves as a guide when assembling and disassembling the drive module 300 and the power module 400, making their assembly and disassembly convenient. Furthermore, the width of the first guide strip 103 gradually widens from the drive module 300 to the power module 400, and the width of the first guide channel 302 also gradually widens from the drive module 300 to the power module 400. This design allows the narrower portion of the first guide strip 103 to be inserted into the wider portion of the first guide channel 302 first, facilitating insertion of the first guide strip 103 into the first guide channel 302. Similarly, the width of the second guide bar 104 gradually expands from the power module 400 to the drive module 300, and the width of the second guide channel 402 gradually expands from the power module 400 to the drive module 300. This arrangement allows the narrower part of the second guide bar 104 to be inserted into the wider part of the second guide channel 402 first, making it easier for the second guide bar 104 to be inserted into the second guide channel 402.

[0049] To easily determine whether the drive module 300 and power module 400 are properly inserted into the end of the fan barrel 100, please refer to [link / reference needed]. Figures 2 to 5 In one embodiment of this application, the inner peripheral wall of the fan cylinder 100 is provided with an air guide 110 extending circumferentially thereon. The two ends of the air guide 110 in the axial direction of the fan cylinder 100 abut against the drive module 300 and the power module 400 respectively. With this configuration, when the drive module 300 or the power module 400 is to be inserted into the end of the fan cylinder 100, the drive module 300 or the power module 400 is first inserted into the end of the fan cylinder 100 until the drive module 300 or the power module 400 abuts against the end of the air guide 110 in the axial direction of the fan cylinder 100, so that it can be known that the drive module 300 or the power module 400 has been inserted in place.

[0050] Further, please refer to Figures 2 to 5 The air guide 110 is located at one end of the fan cylinder 100 in the circumferential direction adjacent to the air inlet area 101, and at the other end of the fan cylinder 100 in the axial direction adjacent to the air outlet area 102. This arrangement allows the air guide 110 to guide the airflow from the air inlet area 101 to the air outlet area 102 when the drive module 300 drives the fan wheel 200 to rotate, thereby reducing wind loss and enhancing the air outlet effect.

[0051] And, please see Figure 4 and Figure 5The outer peripheral wall of the air guide 110 has circumferentially extending plates 111 at both ends of the fan cylinder 100. Each plate 111 has an insertion notch 1111 on its outer side, and the inner peripheral wall of the fan cylinder 100 has an axially extending insertion protrusion 105. The insertion protrusion 105 engages with the insertion notch 1111, thus facilitating the installation of the air guide 110. Obviously, one or more insertion notches 1111 and insertion protrusions 105 can be used, and no specific limitation is made here. Furthermore, the air guide 110 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.

[0052] To facilitate the electrical connection between the drive module 300 and the power module 400 via wires, in one embodiment of this application, please refer to... Figures 2 to 5 The inner peripheral wall of the fan cylinder 100 is provided with a partition 120. The partition 120 and the inner peripheral wall of the fan cylinder 100 surround each other to form a wire passage 121 extending along the axial direction of the fan cylinder 100. The drive module 300 is provided with a drive wire passage port 303 communicating with the wire passage port 121. The power module 400 is provided with a power wire passage port 403 communicating with the wire passage port 121. With this configuration, one end of the wire is first connected to the drive module 300, and then the other end of the guide is passed through the drive wire passage port 303, the wire passage 121 and the power wire passage port 403 in sequence and then electrically connected to the power module 400, so as to realize the electrical connection between the drive module 300 and the power module 400.

[0053] The installation method of the separator 120 is the same as the fixed connection or detachable connection in the above embodiments, and is not specifically limited here. In other embodiments, a wire passage groove can be formed directly on the inner peripheral wall of the fan cylinder 100, or a wire passage channel 121 can be formed by enclosing a structural component on the outer peripheral wall of the fan cylinder 100.

[0054] Further, please refer to Figures 2 to 5The two ends of the separator 120 in the axial direction of the fan cylinder 100 abut against the drive module 300 and the power module 400 respectively. The separator 120 has a first position 122 at the end near the drive module 300, and the air guide 110 has two spaced second positions 112 at the end near the drive module 300. The first position 122 and the two second positions 112 are arranged in a triangle. The first position 122 and the two second positions 112 are fixed to the drive module 300 by bolts. This makes the fixing force on the drive module 300 triangularly distributed, thereby enhancing the stability of the drive module 300. Similarly, the separator 120 has a third position 123 at one end near the power module 400, and the air guide 110 has two spaced fourth positions 113 at one end near the power module 400. The third position 123 and the two fourth positions 113 are arranged in a triangle. The third position 123 and the two fourth positions 113 are all fixed to the power module 400 by bolts. This makes the fixing force on the power module 400 triangularly distributed, thereby enhancing the stability of the power module 400.

[0055] There are many types of the power module 400 mentioned above; please refer to [link / reference]. Figure 2 and Figure 8 In one embodiment of this application, the power module 400 includes a housing 410, two batteries 420, and a pressing member 430. The housing 410 is located at one end of the fan cylinder 100 that is axially away from the drive module 300, and the side of the housing 410 facing away from the drive module 300 is provided with a receiving groove 411. The two batteries 420 are placed in parallel in the receiving groove 411, and the pressing member 430 is detachably installed in the receiving groove 411 and presses the two batteries 420 against the bottom of the receiving groove 411.

[0056] With the above technical solution, when assembling the power module 400, first place the two batteries 420 in parallel at the bottom of the receiving slot 411, then detachably install the pressing member 430 in the receiving slot 411, and press the two batteries 420 against the bottom of the receiving slot 411, thus completing the assembly of the power module 400; when disassembling the power module 400, first remove the pressing member 430 from the receiving slot 411, releasing the constraint on the two batteries 420, and then remove the two batteries 420 from the receiving slot 411, thus completing the disassembly of the power module 400.

[0057] In other embodiments, the power module 400 may also be configured as a battery pack and a battery casing covering the battery pack, or the power module 400 may be directly configured as a battery pack.

[0058] There are many ways in which the aforementioned pressing member 430 can be detachably installed in the receiving groove 411; please refer to [the relevant documentation]. Figure 2 and Figure 8In one embodiment of this application, a reinforcing rib 412 is provided between two opposing sides of the inner peripheral wall of the receiving groove 411. The reinforcing rib 412 is located between the two batteries 420, and a plug-in portion 4121 is provided in the middle of the reinforcing rib 412. A plug-in interface 431 that engages with the plug-in portion 4121 is provided in the middle of the pressing member 430, and the two ends of the pressing member 430 press the two batteries 420 against the bottom of the receiving groove 411. With this configuration, the pressing member 430 can be detachably installed through the cooperation of the plug-in portion 4121 and the plug-in interface 431. Obviously, in other embodiments, the pressing member 430 can also be configured with the detachable installation method described in the above embodiment, which will not be elaborated here.

[0059] Specifically, the two ends of the pressing member 430 along its length are also fixed to the bottom of the receiving groove 411 by bolts, which can enhance the stability of the pressing member 430.

[0060] Further, please refer to Figure 8 The surface of the housing 410 adjacent to the opening of the receiving groove 411 is also provided with a first annular groove 413 surrounding the receiving groove 411. The first annular groove 413 communicates with the receiving groove 411. The power module 400 also includes a power end cover 440, which cooperates with the first annular groove 413 and presses against the pressing member 430, thereby enhancing the stability of the battery 420. Furthermore, the reinforcing rib 412 is provided with two first mating posts 4122, and the insertion part 4121 and the pressing member 430 are located between the two first mating posts 4122. The power end cover 440 is provided with two arc-shaped first countersunk through holes 441, and each of the two first countersunk through holes 441 is provided with a first countersunk sleeve 442. The two first countersunk sleeves 442 are correspondingly fitted with the two first mating posts 4122, thereby enhancing the stability of the power end cover 440.

[0061] Furthermore, please refer to Figure 8 The power supply end cover 440 has a first groove 443 on the side facing away from the pressing member 430. The bottom of the first groove 443 has a first buckle 444. The power module 400 also includes a power supply outer cover 450 that cooperates with the first groove 443. The power supply outer cover 450 has a first buckle 451 that cooperates with the first buckle 444.

[0062] To enhance the heat dissipation of battery 420, in one embodiment of this application, please refer to... Figure 8The housing 410 is also provided with a heat dissipation notch 414 that communicates with the inner peripheral wall of the receiving groove 411. The end of the battery 420 is exposed in the heat dissipation notch 414. With this arrangement, on the one hand, when the desktop high-speed tower fan 1000 stops running, the heat generated by the battery 420 can be dissipated through the heat dissipation notch 414. On the other hand, when the desktop high-speed tower fan 1000 is running, part of the airflow generated by the rotation of the fan wheel 200 will be blown towards the battery 420 in the receiving groove 411 through the assembly gap between the power module 400 and the fan cylinder 100 and the heat dissipation notch 414, which can achieve the purpose of cooling the battery 420.

[0063] Further, please refer to Figure 8 The outer peripheral wall of the housing 410 is provided with a clearance space 415 that communicates with the heat dissipation gap 414. The clearance space 415 is provided through the side of the drive module 300, so that the airflow generated by the rotation of the fan wheel 200 can be blown to the battery 420 through the clearance space 415 and the heat dissipation gap 414, thereby enhancing the heat dissipation effect of the battery 420.

[0064] Specifically, there are four heat dissipation gaps 414 and four clearance spaces 415. Each heat dissipation gap 414 is connected to the corresponding clearance space 415. The two ends of one battery 420 are exposed from two heat dissipation gaps 414, and the two ends of another battery 420 are exposed from the other two heat dissipation gaps 414. This can further enhance the heat dissipation effect of the battery 420.

The drive module 300 may also include a drive housing, a motor and a control circuit board 330. The drive housing has an installation space, and the motor and the control circuit board 330 are both located in the installation space.

[0068] Further, please refer to Figure 10 The outer casing 310, adjacent to the opening of the second mounting groove 312, is also provided with a second annular groove 313 surrounding the receiving groove 411. The second annular groove 313 communicates with the second mounting groove 312. The drive module 300 also includes an outer end cover 340, which cooperates with the second annular groove 313 to seal the second mounting groove 312. Furthermore, the second mounting groove 312 is provided with three second mating posts 314 arranged in a triangle, and the outer end cover 340 is provided with three arc-shaped second countersunk through holes 341. Each second countersunk through hole 341 is provided with a second countersunk sleeve 342. The three first countersunk sleeves 442 are correspondingly fitted with the three first mating posts 4122, which can enhance the stability of the outer end cover 340.

[0069] Furthermore, please refer to Figure 10 The outer end cover 340 has a second groove 343 on the side facing away from the power module 400. The bottom of the groove 343 has a second buckle 344. The drive module 300 also includes a decorative cover 350 that cooperates with the second groove 343. The decorative cover 350 has a second buckle 351 that cooperates with the second buckle 344.

[0070] It should be noted that the fan tube 100 can be placed horizontally or vertically. The following text will describe the fan tube 100 in both horizontal and vertical positions.

[0071] Please see Figure 1 When the fan barrel 100 is placed horizontally, the desktop high-speed fan also includes a support 500. The support 500 has two connecting ends 501 arranged opposite to each other. The two connecting ends 501 are connected to the drive module 300 and the power module 400 respectively. In this way, the support 500 can support the drive module 300, the power module 400, the fan barrel 100 and the fan wheel 200, which facilitates airflow through the horizontally placed fan barrel 100. The connection method of the connecting ends 501 is set as in the above embodiment, which is either a fixed connection or a detachable connection, and will not be described in detail here.

[0072] Please see Figure 11When the fan barrel 100 is placed vertically, the desktop high-speed fan also includes a base 600, with the drive module 300 connected to the base 600. This allows the base 600 to support the drive module 300, power module 400, fan barrel 100, and fan wheel 200, enhancing the stability of the desktop high-speed fan. The connection method of the base 600 is set according to the fixed connection or detachable connection methods described in the above embodiments, and will not be elaborated further here. In other embodiments, the power module 400 may also be connected to the base 600.
