DETAILED DESCRIPTION

[0052] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0053] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0054] In the description of the present utility model, it should be noted that the terms "upper", "lower", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or are directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model.

[0055] like Figure 1As shown, this embodiment provides a direction switching system, which is applicable to airflow regulating devices such as fans, heaters, and circulating fans. Specifically, the direction switching system of the airflow regulating device includes a functional component, a column 200, a steering motor 7, and a transmission assembly. For different devices, the functional component is different, which can be any one of a fan host 100, a heater host, and a circulating fan host. In this embodiment, the functional component is a fan host 100.

[0056] like Figure 1-6 As shown, a chassis 300 is provided at the lower end of the column 200, and the airflow regulating device is vertically arranged on the load-bearing surface through the chassis 300. The column 200 includes a guide plate 2 located at the upper end, and the guide plate 2 includes a plate body 21 on the upper side and a ring column 22 on the lower side. A lower guide hole L2 is provided in the middle of the guide plate 2, which passes through the ring column 22 from the plate body 21, and a vertical guide shaft 3 is rotatably provided in the lower guide hole L2. The functional component includes a shell 1, and a mounting portion 11 is fixed in the shell 1. The steering motor 7 is fixed on the mounting portion 11, and the mounting portion 11 is provided with an upper guide hole L1 for the upper end of the guide shaft 3 to pass through. The upper guide hole L1 and the lower guide hole L2 are coaxial, and together constitute a space to limit the radial movement of the guide shaft 3.

[0057] like Figure 2 , 5 , 6, and the lower end of the housing 1 has a sleeve portion 12; the sleeve portion 12 is movably sleeved on the upper end of the column 200, and a sleeve 4 is provided between the sleeve portion 12 and the disk body 21 of the guide disk 2. The transmission assembly includes an eccentric sleeve 6 and a transmission member 5 connected to the output end of the steering motor 7, and the two sides of the transmission member 5 are respectively rotatably connected to the eccentric end of the eccentric sleeve 6 and the disk body 21. When the steering motor 7 is running, it drives the eccentric sleeve 6 to rotate, thereby driving the transmission member 5 to rotate eccentrically and forming a force on the guide disk 2. Since the guide disk 2 is fixed on the column 200, the driving relative active force is reversely applied to itself, thereby forcing the housing 1 fixed with the steering motor 7 to reciprocate with limited amplitude. In this movement, the housing 1 reciprocates with limited amplitude relative to the column 200 in a manner that the sleeve portion 12 surrounds the guide disk 2.

[0058] Through the above-mentioned structural arrangement, firstly, the coaxial sleeve 4 connection of the sleeve 12, the guide plate 2 and the sleeve 4 makes the circumferential rotation more stable, and the sleeve 4 located between the sleeve 12 and the guide plate 2 plays a guiding and supporting role in the rotation of the housing 1, reducing the circumferential shaking during the rotation, improving the stability, and making the rotation smoother. Moreover, the sleeve 4 can fine-tune the gap along the circumferential direction, so that a suitable rotation gap is maintained between the sleeve 12 and the guide plate 2, so that no large friction resistance is formed between the sleeve 12 and the guide plate 2, thereby further improving the smoothness of the rotation and reducing the noise. In addition, the guide shaft 3 that runs through the mounting portion 11 and the guide plate 2 further guides the rotation of the housing 1 in the circumferential direction through the limiting effect of the center, further improving the stability and smoothness of the rotation. In summary, the sleeve 4 and the guide shaft 3 play a guiding and supporting role in the rotation of the functional component, preventing the functional component from shaking when it swings and rotates. The setting of the guide shaft 3 further improves the rigidity of the connection between the two, thereby increasing the connection strength.

[0059] In terms of material selection, the guide plate 2 and the sleeve 4 are made of polyformaldehyde, which has the advantages of high strength, high elastic modulus, high hardness and good impact strength, making the connection structure more stable. In addition, the polyformaldehyde surface is glossy and has good self-lubricating properties, making the relative rotation between the components smoother and less prone to jamming. Further preferably, the guide shaft 3 is made of stainless steel, so that its metal rigidity can be used to reinforce the connection between the upper and lower components.

[0060] In this embodiment, if Figure 1-2 As shown, the fan main unit 100 includes a fan head 101 and a fuselage 102. The fan head 101 and the fuselage 102 are fixedly connected, and the fuselage 102 is rotatably connected to the column 200. The fuselage 102 includes a housing 1 connected to the fan head 101. The steering motor 7 that drives the fan main unit 100 to rotate around the column 200 to achieve direction switching is located in the housing 1 of the fuselage 102.

[0061] Furthermore, if Figure 1-2 As shown in , 4, the shell 1 of the fuselage part 102 includes a vertical section 102a coaxial with the column 200 on the lower side and a curved section 102b bent backward on the upper side and connected to the rear of the fan head part 101; the steering motor 7 is located in the vertical section 102a and in the front part of the vertical section 102a. Usually, the main motor driving the fan blades is located at the rear side of the fan head part 101. Therefore, setting the steering in the vertical section 102a not only keeps the two apart to avoid heat dissipation interference between the two, but also makes the center of gravity of the equipment more centered, further improving stability.

[0062] like Figure 3 , 4As shown in Figures 6 and 7, the transmission member 5 is an arc-shaped transmission plate, and the two ends of the transmission plate are respectively provided with a first connection hole 51 and a second connection hole 52; the eccentric end of the eccentric sleeve 6 is inserted into the first connection hole 51, and the upper end of the disc body 21 is provided with a boss 23, which is inserted into the second connection hole 52. Through this connection method, the rotation angle of the functional component is increased in a limited space.

[0063] like Figure 3-6 As shown, the mounting portion 11 is a motor bracket fixed on the main housing. For ease of assembly, the mounting portion 11 and the main housing are initially independent components. The two are fixed to each other by fasteners in the subsequent assembly process to form a housing 1 of the functional component. The steering motor 7 is mounted on the motor bracket, and the motor bracket is provided with a through hole for the output shaft of the steering motor 7 to pass through. An eccentric sleeve 6 is provided on the lower side of the motor bracket, and the eccentric sleeve 6 includes a connecting sleeve 61 connected to the lower end of the output shaft of the steering motor 7 and a cylindrical protrusion 62 located on the side of the connecting sleeve 61 and protruding downward. The cylindrical protrusion 62 is inserted into the first connecting hole 51 of the transmission plate.

[0064] like Figure 5-7 As shown, the upper edge of the disk body 21 is provided with a circumferential first ring portion 21a, and the lower side of the first ring portion 21a forms a circumferential body 21b with a smaller diameter than the first ring portion 21a; the upper edge of the sleeve 4 is provided with a circumferential second ring portion 41; the upper edge of the sleeve portion 12 extends into the shell 1 to form an annular high protrusion 12a, and the first ring portion 21a, the second ring portion 41 and the annular high protrusion 12a are stacked in sequence from top to bottom. The guide disk 2 is fixed to the column 200, so that an axial space adapted to the rotation of the shell 1 is formed between the first ring portion 21a and the annular high protrusion 12a, and the second ring portion 41 is located in the axial space, thereby realizing the limited connection of the sleeve 4, and at the same time, the gap between the two is adaptively adjusted, thereby improving the stability and smoothness of the rotation of the shell 1.

[0065] like Figure 3 , 5 -7, the guide shaft 3 is provided with an annular protrusion 31 protruding from the outer peripheral wall; the diameter of the annular protrusion 31 is larger than the lower guide hole L2, so as to limit the guide shaft 3 from disengaging from the lower guide hole L2 downward, and the lower side of the motor bracket is supported by the upper surface of the annular protrusion 31. The lower section of the guide shaft 3 is provided with a retaining spring groove v recessed in the outer peripheral wall, and the retaining spring groove v is exposed in the lower guide hole L2. The retaining spring located in the retaining spring groove v limits the guide shaft 3 from jumping upward. In this way, the guide shaft 3 is prevented from jumping up and down, and the guide shaft 3 is prevented from being slightly deflected, which is beneficial to the realization of its guiding and connecting functions. The upper surface of the annular protrusion 31 does not support the lower side of the mounting portion 11 rigidly, and a preferred method such as a rolling bearing can be adopted between the two, so that the two can rotate smoothly relative to each other, and the upper surface of the annular protrusion 31 can also support the motor bracket.

[0066] like Figure 5 As shown, a countersunk hole s is provided on the upper surface of the guide plate 2 , and the annular protrusion 31 is located in the countersunk hole s. The lower end of the motor bracket is provided with an annular flange m surrounding the upper guide hole L1 , and the diameter of the annular flange m is adapted to the annular protrusion 31 .

[0067] like Figure 1-2 As shown, in order to facilitate the installation of the column 200, it also includes a column body 201 and a connecting seat 202. The guide plate 2 is fixedly connected to the connecting seat 202. When leaving the factory, the guide plate 2 and the connecting seat 202 are fixed to one end of the functional component to form a modular component, and the column body 201 is separated from it. During assembly, the modular components are docked in a manner that the connecting seat 202 is coaxially fixed to the upper side of the column body 201 to complete the assembly of the whole machine. Such a modular setting is convenient for packaging, transportation in transit, and on-site assembly.

[0068] Preferably, if Figure 1-2 As shown in Figures 5 and 7, the connection seat 202 is assembled with the column body 201 through the connection head 203 fixedly connected to the lower side of the connection seat 202; a nut seat f is provided in the inner cavity of the column body 201, and a stud j is provided at the lower section of the connection head 203, and the stud j is screwed and plugged with the nut seat f; the annular lower end surface of the connection seat 202 abuts against the annular upper end surface of the column body 201. This connection method not only has high connection strength and good stability, but is also convenient and easy to operate.

[0069] Preferably, if Figure 5 , 7 As shown, the upper edge of the connecting seat 202 is provided with a stepped annular recess p which is recessed inwardly into the outer peripheral wall, and the annular lower end surface of the shaft sleeve 4 is supported by the stepped annular recess p.
