Description

Technical Field

[0001] This application relates to the field of fan technology, and more specifically, to a horizontal desktop 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] Generally, a swing-out air grille is installed at the air outlet of the fan barrel to adjust the airflow direction. However, adjusting the airflow direction by swinging the air grille left and right limits the adjustment angle to a certain range, which limits the applicable application scenarios. Therefore, it is in urgent need of improvement. Utility Model Content

[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 horizontal desktop tower fan, in which the two mounting ends of the bracket are rotatably connected to the two ends of the fan cylinder along the axial direction, so that the fan cylinder is horizontally placed and mounted on the desktop. With the addition of a drive device located on the fan cylinder to drive the fan cylinder to rotate relative to the bracket, the air outlet angle of the fan cylinder can be infinitely adjusted by driving the fan cylinder to rotate relative to the bracket, so that the horizontal desktop tower fan can be used in more usage scenarios and improve the user experience.

[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 Figure 1 and Figure 2 This application provides a horizontal desktop tower fan 1000, which includes a fan cylinder 100, a bracket 200, and a drive device 300.

[0034] The fan barrel 100 provides mounting space for the drive unit 300 and other components that will be described below. The fan barrel 100 has many shapes, such as cylindrical, square, or other shapes, and is not specifically limited here.

[0035] Please see Figure 1 and Figure 3 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 by directly penetrating 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.

[0036] The fan cylinder 100 is horizontally positioned. Obviously, when the fan cylinder 100 is horizontally positioned, its axis can be parallel to the horizontal direction, or it can be slightly inclined relative to the horizontal direction; no specific limitation is made here. Furthermore, in this embodiment, the fan cylinder 100 is a cylindrical shape with open ends, so that other components of the drive device 300 can be installed inside the fan cylinder 100 through the open ends. In other embodiments, the fan cylinder 100 can also be a cylindrical shape with closed ends; in this case, the fan cylinder 100 is formed by joining two semi-cylinders symmetrically positioned about its axis.

[0037] Please see Figure 1 and Figure 4 The bracket 200 is used to support the fan cylinder 100 so that the fan cylinder 100 can be placed horizontally and mounted on the table. The bracket 200 has two mounting ends 201 arranged coaxially and spaced apart. The two mounting ends 201 are rotatably connected to the two ends of the fan cylinder 100 in the axial direction. The driving device 300 is provided on the fan cylinder 100 and is used to drive the fan cylinder 100 to rotate relative to the bracket 200.

[0038] In this embodiment, the rotatable connection between each assembly end 201 and the corresponding axial end of the fan barrel 100 is configured as a detachable rotatable connection. The specific structure of the detachable rotatable connection will be described below. This configuration facilitates the assembly and disassembly of each assembly end 201 and the corresponding axial end of the fan barrel 100. In other embodiments, the rotatable connection between each assembly end 201 and the corresponding axial end of the fan barrel 100 can also be configured as a non-detachable rotatable connection.

[0039] Similarly, the connection method between the drive unit 300 and the fan barrel 100 can be set with reference to the fixed connection method described above, or it can be set with reference to the detachable connection method described above. No specific limitation is made here.

[0040] Through the above technical solution, in this application, the two mounting ends 201 of the bracket 200 are rotatably connected to the two ends of the fan cylinder 100 in the axial direction. With the drive device 300 located on the fan cylinder 100 and used to drive the fan cylinder 100 to rotate relative to the bracket 200, the air outlet angle of the fan cylinder 100 can be infinitely adjusted by rotating the fan cylinder 100 relative to the bracket 200 through the drive device 300. This makes the horizontal desktop tower fan 1000 suitable for more usage scenarios and improves the user experience.

[0041] There are many types of the aforementioned drive unit 300; please refer to [link / reference]. Figure 1 , Figure 2 and Figure 4 In one embodiment of this application, both assembly ends 201 are detachably rotatably connected to shafts 210, and the two shafts 210 are detachably fixedly connected to the two ends of the fan barrel 100 in the axial direction. The driving device 300 includes a driving member 310, which is disposed on the fan barrel 100, and the output shaft of the driving member 310 is drivenly connected to a shaft 210 to drive the fan barrel 100 to rotate relative to the bracket 200. With this arrangement, on the one hand, the rotational assembly of the bracket 200 and the fan barrel 100 is realized through the two shafts 210, and on the other hand, the driving member 310 is drivenly connected to the shaft 210 so that the driving member 310 can drive the fan barrel 100 to rotate relative to the bracket 200.

[0042] There are many types of driving components 310. The driving component 310 can be a rotating element such as a motor or a rotary cylinder, and no specific limitation is made here. In addition, in other embodiments, the assembly end 201 may be provided with a circular track, and the end of the fan cylinder 100 may be provided with a sliding member that slides with the track. This can also achieve a rotatable connection between the assembly end 201 and the end of the fan cylinder 100. In this case, the sliding member can be driven to slide along the track by a crank-rocker mechanism.

[0043] There are many ways to connect the output shaft of the drive unit 310 and the shaft 210 in a transmission manner; please refer to [link / reference needed]. Figure 1 , Figure 2 and Figure 4 The drive unit 300 also includes a first gear 320 and a second gear 330 that mesh with each other. The outer diameter of the first gear 320 is smaller than that of the second gear 330. The first gear 320 is fixed to the output shaft of the drive member 310, and the second gear 330 is fixed to a shaft member 210. With this configuration, when the output shaft of the drive member 310 rotates forward and backward, it simultaneously drives the first gear 320 to rotate forward and backward. The forward and backward rotation of the first gear 320 drives the second gear 330 and the shaft member 210 to rotate, thereby causing the fan cylinder 100 to rotate relative to the support 200. Furthermore, because the outer diameter of the first gear 320 is smaller than that of the second gear 330, the first gear 320 and the second gear 330 are a small gear driving a large gear. This transmission method of a small gear driving a large gear has the advantages of high transmission efficiency and strong load-bearing capacity.

[0044] In other embodiments, the output shaft of the drive member 310 may have a built-in first pulley, and the shaft member 210 may have a built-in second pulley. A belt may be wound around the first and second pulleys, and the output shaft of the drive member 310 and the shaft member 210 may be connected by the first pulley, the second pulley, and the belt. Furthermore, in other embodiments, the drive device 300 may be simply a motor, with the motor's output shaft directly fixed to the shaft member 210, which can also drive the fan cylinder 100 to rotate relative to the bracket 200.

[0045] There are many types of the aforementioned bracket 200; please refer to [link / reference]. Figure 4 In one embodiment of this application, the bracket 200 includes a main body 220 and two support parts 230. The main body 220 is horizontally placed and U-shaped. The two support parts 230 are inclined in the vertical direction. The lower ends of the two support parts 230 are connected to the two ends of the main body 220 at acute angles. The upper ends of the two support parts 230 are formed into two assembly ends 201. With this configuration, the bracket 200 has strong structural stability and strong load-bearing capacity due to the U-shaped configuration of the main body 220 and the acute angle connection between the lower ends of the two support parts 230 and the two ends of the main body 220.

[0046] Furthermore, the connection between the support part 230 and the main body 220 is arc-shaped, which can enhance the connection strength between the support part 230 and the main body 220.

[0047] Preferably, the angle between each support 230 and the main body 220 is 45 degrees, which can further improve the stability and load-bearing capacity of the bracket 200. In addition, the angle between each support 230 and the main body 220 can also be other values ​​such as 30 degrees, 35 degrees, 40 degrees, 50 degrees, 55 degrees, 60 degrees, and 65 degrees.

[0048] In other embodiments, the bracket 200 may also include two T-shaped frames, with the lower ends of the two frames placed on the table and the upper ends of the two frames rotatably connected to the two ends of the fan cylinder 100 in the axial direction.

[0049] There are many ways to detachably rotate the assembly end 201 and the shaft 210; please refer to [the relevant documentation]. Figure 2 and Figure 4 In one embodiment of this application, both ends of the fan cylinder 100 are fixedly provided with bushings 103 in the axial direction, and each assembly end 201 is provided with a through hole 231; each shaft 210 includes a screwing part 211 and a shaft part 212 connected to the screwing part 211. Each shaft part 212 passes through the corresponding through hole 231 and is threaded into the corresponding bushing 103. Each screwing part 211 abuts against the side of the corresponding assembly end 201 facing away from the corresponding bushing 103. Obviously, each shaft part 212 is rotatably engaged with the corresponding through hole 231 so that each shaft part 212 can rotate within the through hole 231.

[0050] Specifically, the outer periphery of the bushing 103 is fitted with the inherent bearing 1031, and the second gear 330 is sleeved on the outer peripheral wall of the bearing 1031. The second gear 330 is fixed to the mounting end 201 of the support portion 230 by the outer cover 710 (hereinafter referred to as the outer cover), so that the second gear 330 is indirectly fixed to the shaft portion 212 of the shaft member 210. Alternatively, the shaft member 210 may be directly fixed to the end of the fan cylinder 100, and the second gear 330 may be directly fixed to the outside of the shaft member 210.

[0051] In other embodiments, the assembly end 201 may be provided with a through hole 231, and the shaft 210 may be inserted into the through hole 231. Two nuts may be threaded onto the outer peripheral wall of the shaft 210. The two nuts may be respectively abutted against the side of the assembly end 201 facing the fan cylinder 100 and the side of the assembly end 201 facing away from the fan cylinder 100. The end of the shaft 210 may be fixed to the fan cylinder 100 by means of snap-fit ​​connection or magnetic connection.

[0052] Further, please refer to Figure 2 , Figure 4 and Figure 5 Each bushing 103 contains a threaded sleeve 104, and each threaded sleeve 104 is threadedly screwed onto the corresponding shaft portion 212. This arrangement facilitates the installation of internal threads. Specifically, the outer peripheral wall of the threaded sleeve 104 has two protrusions 1041 spaced apart along its axial direction. Each protrusion 1041 extends circumferentially along the threaded sleeve 104 and is arranged in a ring. The outer peripheral wall of each protrusion 1041 is interference-fitted with the inner peripheral wall of the corresponding bushing 103, which enhances the stability of the threaded sleeve 104. In addition, each protrusion 1041 can also be elastic, so that the outer peripheral wall of each protrusion 1041 is elastically squeezed and clamped by the inner peripheral wall of the corresponding bushing 103, thereby fixing the threaded sleeve 104.

[0053] Using the above technical solution, when assembling the bracket 200 and the fan cylinder 100, first hold the screwing part 211 of each shaft 210, pass the shaft part 212 of each shaft 210 through the corresponding through hole 231, and then screw the screwing part 211 of each shaft 210 so that the shaft part 212 of each shaft 210 is threaded into the corresponding bushing 103, until each screwing part 211 abuts against the corresponding support part 230, thus completing the assembly of the bracket 200 and the fan cylinder 100. Assembly; When separating the bracket 200 and the fan cylinder 100, first hold the screwing part 211 of each shaft 210, so that the shaft part 212 of each shaft 210 is screwed out from the corresponding bushing 103, and then each shaft part 212 is pulled out from the corresponding through hole 231, thus completing the separation of the bracket 200 and the fan cylinder 100; in this way, the rotational connection between each assembly end 201 and the corresponding end of the fan cylinder 100 in the axial direction is the detachable rotational connection mentioned above.

[0054] In other embodiments, the shaft 210 may also be configured as a rotating shaft, with one end of the rotating shaft fixed to the end of the fan cylinder 100, and the other end of the rotating shaft fitted with a bearing component. The inner circumference of the bearing component is fixed to the rotating shaft, and the outer circumference assembly end 201 of the bearing component is fixed to it.

[0055] Please see Figure 2 and Figure 4 To enhance the rotational stability of each shaft 210, in one embodiment of this application, the bracket 200 further includes two limiting sleeves 240. Each limiting sleeve 240 is fitted onto the corresponding assembly end 201, and each limiting sleeve 240 is provided with a through hole 241 communicating with the corresponding through hole 231. Each shaft portion 212 passes through the corresponding through hole 241 and the corresponding through hole 231 and is threaded into the corresponding bushing 103. Each screwing portion 211 abuts against the side of the corresponding limiting sleeve 240 facing away from the corresponding bushing 103. This arrangement allows the shaft portion 212 of each shaft 210 to rotate within the limiting sleeve 240, thereby effectively reducing the vibration amplitude of each shaft 210 during rotation and enhancing the rotational stability of each shaft 210.

[0056] It is understandable that the through hole 241 of the limiting sleeve 240 penetrates the two sides of the limiting sleeve 240 that are arranged opposite to each other. The through hole 241 has two parts. When the limiting sleeve 240 is fitted on the support part 230, the two parts of the through hole 241 are located on both sides of the through hole 231.

[0057] Please see Figure 1 and Figure 4To enhance the placement stability of the bracket 200, in one embodiment of this application, the horizontal desktop tower fan 1000 further includes a base pad 400. The base pad 400 is provided with an inverted L-shaped snap-fit ​​member 410. The middle part of the main body 220 is snapped between the base pad 400 and the snap-fit ​​member 410. Specifically, the main body 220 has a first segment 221 and two parallel second segments 222. The two second segments 222 are vertically connected to the two ends of the first segment 221. The middle part of the first segment 221 is snapped between the base pad 400 and the snap-fit ​​member 410. With this arrangement, when the bracket 200 is placed on the desktop, the friction between the bracket 200 and the desktop can be enhanced by the base pad 400, thereby enhancing the placement stability of the bracket 200.

[0058] Specifically, the base pad 400 and the snap-fit ​​part 410 are formed from a single sheet of material. The middle part of the sheet is die-cast to form the snap-fit ​​part 410, while the other parts of the sheet are formed to form the base pad 400. This makes the forming of the base pad 400 and the snap-fit ​​part 410 convenient.

[0059] Preferably, please refer to Figure 1 and Figure 6 The lower surface of the base pad 400 is provided with a groove 401, and a friction pad 420 is embedded in the groove 401 to further enhance the friction between the bracket 200 and the desktop bracket 200, thereby further enhancing the placement stability of the bracket 200. Obviously, the lower surface of the friction pad 420 can be provided with a V-shaped anti-slip texture to prevent the bracket 200 from being accidentally pushed.

[0060] Please see Figure 3 and Figure 7 Considering that the horizontal desktop tower fan 1000 also includes a fan wheel 500 and a power unit 600, the fan wheel 500 is located inside the fan cylinder 100, and the output end of the power unit 600 is coaxially connected to the fan wheel 500, if the position of the power unit 600 and the position of the drive device 300 can be concentrated together, it will be convenient for the wiring of the horizontal desktop tower fan 1000. Therefore, in one embodiment of this application, the power unit 600 and the drive device 300 are integrated. The type of the power unit 600 is set with reference to the type of the drive unit 310 in the above embodiment, and will not be described in detail here. Specifically, the horizontally mounted desktop tower fan 1000 also includes an integrated housing 700, which is inserted into one axial end of the fan cylinder 100. The integrated housing 700 has a first mounting groove 701 on the side facing the fan wheel 500 and a second mounting groove 702 surrounding the first mounting groove 701 on the side facing away from the fan wheel 500. The power component 600 and the drive device 300 are respectively disposed in the first mounting groove 701 and the second mounting groove 702.

[0061] Through the above technical solution, when disassembling and assembling the power component 600 and the drive device 300, the integrated housing 700 can be inserted into or removed from the end of the fan cylinder 100, thus completing the disassembly and assembly of the power component 600 and the drive device 300 simultaneously, and enabling the disassembly and assembly of the drive component 310 and the drive device 300. Furthermore, the arrangement of the second mounting groove 702 surrounding the first mounting groove 701 allows the space of the integrated housing 700 in the axial direction of the fan cylinder 100 to be shared by the power component 600 and the drive device 300, thereby reducing the size of the integrated housing 700.

[0062] In other embodiments, the drive device 300 can be configured as a motor, which is directly fixed together with the power component 600, thus achieving the integrated configuration of the power component 600 and the drive device 300.

[0063] Please see Figure 3 and Figure 7 In order to facilitate the rotatable connection between the two assembly ends 201 and the two ends of the fan cylinder 100, in one embodiment of this application, the horizontal desktop tower fan 1000 also includes a housing 800. The housing 800 is inserted into the end of the fan cylinder 100 that is axially away from the integrated housing 700, and the two assembly ends 201 are rotatably connected to the integrated housing 700 and the housing 800 respectively.

[0064] Specifically, the housing 800 has a receiving groove 801 on the side facing away from the integrated housing 700, and the two bushings 103 are fixedly installed in the second mounting groove 702 and the first mounting groove 701 respectively, which makes it convenient to install the bushings 103.

[0065] Further, please refer to Figure 3 and Figure 7 An outer cover 710 is provided on the side of the integrated housing 700 facing away from the fan wheel 500. The outer cover 710 covers the opening of the first mounting groove 701, and the middle of the outer cover 710 is through to allow the corresponding shaft portion 212 to pass through. Similarly, an end cover 810 is provided on the side of the housing 800 facing away from the fan wheel 500. The end cover 810 covers the opening of the receiving groove 801. An outer cover 811 is snap-fitted to the outer side of the end cover 810, and the middle of the end cover 810 and the outer cover 811 are through to allow the corresponding shaft portion 212 to pass through. Furthermore, the second gear 330 is fixedly installed on the inner side of the outer cover 710. The outer cover 710 is clamped and fixed between the bearing 1031 and the support part 230, so that the outer cover 710 and the support part 230 are fixed together, thereby realizing that the second gear 330 and the support part 230 are also fixed together. Obviously, when the outer cover 710 is clamped and fixed, the outer cover 710 and the integrated shell 700 are in clearance fit, so that the integrated shell 700 and the outer cover 710 can rotate relative to each other.

[0066] In addition, the outer cover 710 is provided with a plurality of countersunk channels 711 arranged at intervals along its circumference. Each countersunk channel 711 extends circumferentially along the outer cover 710 and is arranged in an arc shape. Each countersunk channel 711 is provided with a countersunk head 712 that slides with it. The first mounting groove 701 is provided with a plurality of mating parts 703. Each countersunk head 712 is inserted into and mated with the corresponding mating part 703. With this arrangement, when the fan cylinder 100 rotates relative to the bracket 200, each countersunk head 712 rotates within the corresponding countersunk channel 711, thereby enhancing the rotational stability of the integrated shell 710. Furthermore, a decorative cover 713 is fastened to the outer side of the outer cover 710.

[0067] Furthermore, please refer to Figure 3 and Figure 7 The receiving slot 801 houses a power supply 900. The drive unit 310 and drive device 300 are both electrically connected to the power supply 900. The fan barrel 100 has a wiring channel (not shown) connecting the housing 800 and the integrated housing 700 inside or outside, facilitating the electrical connection of the power supply 900 to the drive unit 310 and drive device 300 via wires. Additionally, the end of the fan wheel 500 furthest from the power unit 600 is rotatably connected to the housing 800 to enhance the rotational stability of the fan wheel 500.
