Detailed implementation manners

[0029] In order to enable those skilled in the art of this technology to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the utility model.

[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the utility model.

[0031] Please refer to Figures 1 to 10 , an embodiment of the present utility model provides a tower fan 10, which includes a tower fan body 100, a heightening base 200 and a base 300. The heightening base 200 is detachably connected between the tower fan body 100 and the base 300, and the tower fan body 100 is detachably connected to the base 300. The tower fan 10 can selectively be in a first combined state or a second combined state. When the tower fan 10 is in the first combined state, the tower fan body 100, the heightening base 200 and the base 300 are connected in sequence. When the tower fan 10 is in the second combined state, the tower fan body 100 and the base 300 are connected in sequence. Thus, compared with the tower fans in the related art, the tower fan 10 of the present application can adjust the height according to the actual height of the user by introducing the detachable heightening base 200. When the user is relatively tall, the heightening base 200 can be installed between the tower fan body 100 and the base 300 to increase the overall height of the tower fan 10. For a shorter user, the tower fan body 100 and the base 300 can be directly connected to reduce the height of the tower fan 10. This design greatly improves the applicability of the product and the user experience.

[0032] In addition, this design allows the user to freely adjust the height of the tower fan 10 according to different usage scenarios or personal preferences. For example, in an open space such as a living room, a higher combination method can be selected to promote air circulation; while in a bedroom or other smaller spaces, a lower setting can be selected to save space and maintain beauty. In addition, such flexibility also facilitates cleaning and maintenance work.

[0033] In some embodiments, the heightening base 200 is provided with a cavity 201 and a through hole 202. The through hole 202 communicates with the cavity 201. The heightening base 200 has a first end 210 and a second end 220 which are arranged opposite to each other. The through hole 202 is located at the first end 210. The tower fan body 100 is provided with a connecting member 110, and the connecting member 110 is provided with a connecting convex portion 111. The tower fan 10 further includes a limiting member 400. When the tower fan 10 is in the first combined state, the connecting convex portion 111 passes through the through hole 202, the limiting member 400 is located in the cavity 201 and is connected to the connecting convex portion 111, and the first end 210 is clamped between the connecting member 110 and the limiting member 400.

[0034] Among them, an inner cavity 201 is provided inside the heightening base 200. This cavity 201 provides an installation space for the limiting member 400 and also provides a space into which the connecting member 110 (especially the connecting convex part 111) can extend. The through hole 202 is located at the first end 210 of the heightening base 200. The function of the through hole 202 is to allow the connecting convex part 111 on the tower fan body 100 to pass through, so that the tower fan body 100 can be connected to the heightening base 200. The limiting member 400 is placed in the cavity 201 of the heightening base 200. Its function is to fix the passing connecting convex part 111 when the tower fan 10 is in the first combined state, preventing it from easily detaching or moving.

[0035] In this way, the limiting member 400 further locks the position of the connecting convex part 111, increasing the safety and stability of the structure. The heightening base 200 is firmly fixed under the tower fan body 100 to form an integral whole, ensuring that it will not easily separate even during use.

[0036] In some embodiments, the limiting member 400 is a limiting ring, and the limiting ring is threadedly connected to the connecting convex part 111. In this way, the limiting ring is connected to the connecting convex part 111 through threads, and can provide a very firm mechanical connection method. Threaded connection not only ensures the tightness of the connection, but also allows the user to adjust its position by rotating the limiting ring until the best tightening effect is achieved.

[0037] In addition, the threaded connection provides a self-locking function, which means that even under the action of vibration or external force during use, the limiting ring is not easily loosened. This increases the safety and reliability of the entire structure.

[0038] In some embodiments, the connecting member 110 is provided with a plurality of first positioning parts 112, and the first end 210 is provided with a plurality of second positioning parts 211. Each first positioning part 112 corresponds to a second positioning part 211. When the tower fan 10 is in the first combined state, each first positioning part 112 is in positioning cooperation with the corresponding second positioning part 211. Among them, if the first positioning part 112 is a protrusion, the second positioning part 211 can be a corresponding groove or hole so that the protrusion can be embedded therein. If the first positioning part 112 is a groove or hole, the second positioning part 211 can be a corresponding protrusion to be inserted into the first positioning part 112.

[0039] In this way, by setting the corresponding first positioning parts 112 and second positioning parts 211, it is ensured that the tower fan body 100 and the heightening base 200 can be accurately aligned during assembly. This avoids problems of instability or unsightliness caused by misalignment.

[0040] In addition, the cooperation between the first positioning portion 112 and the second positioning portion 211 not only helps to maintain the correct positional relationship between the components, but also prevents relative movement caused by external forces during use. This can significantly improve the stability and durability of the entire tower fan 10 structure.

[0041] Moreover, the design of the positioning portion can also prevent the tower fan main body 100 from rotating unnecessarily relative to the heightening base 200. This is particularly important for ensuring that the operation panel of the tower fan 10 always faces the correct direction, and at the same time avoids wire entanglement or other safety issues.

[0042] In some embodiments, the heightening base 200 is further provided with an opening 203 which communicates with the cavity 201, and the opening 203 is located at the second end 220. Among them, the size and shape of the opening 203 should be designed to be large enough so that users can easily operate the limiting member 400 through it. Common shapes can be circular, elliptical or rectangular, etc.

[0043] When assembling the tower fan 10, first pass the connecting convex portion 111 on the tower fan main body 100 through the through hole 202 at the first end 210 of the heightening base 200. Then place the limiting member 400 into the cavity 201 of the heightening base 200 from the opening 203 and connect it to the connecting convex portion 111.

[0044] When disassembling the tower fan 10, users can easily access the limiting member 400 through the opening 203 and use an appropriate tool (such as a screwdriver) or manually turn it to loosen the limiting member 400. Once the limiting member 400 is loosened, the tower fan main body 100 can be easily separated from the heightening base 200, so as to perform cleaning, maintenance or other operations.

[0045] In this way, the existence of the opening 203 enables users to directly access the limiting member 400 in the cavity 201 without completely disassembling the entire heightening base 200, greatly simplifying the installation and disassembly process.

[0046] In some embodiments, a plurality of first threaded portions 221 are provided at the edge of the second end 220, and a plurality of second threaded portions 310 are provided on the base 300, and each second threaded portion 310 corresponds to a first threaded portion 221; when the tower fan 10 is in the first combined state, each first threaded portion 221 cooperates with the corresponding second threaded portion 310. Among them, the first threaded portion 221 and the second threaded portion 310 can be threaded holes, and then connected by screws.

[0047] In this way, through the cooperation of the first threaded portion 221 and the second threaded portion 310, a firm mechanical connection is formed between the heightening base 200 and the base 300. Threaded connection can provide a high fastening force to ensure that it will not loosen due to external forces or vibrations during use, thereby enhancing the stability of the entire tower fan 10 structure.

[0048] In addition, the threaded connection not only provides an axial fastening force, but also prevents the heightened seat 200 from rotating relative to the base 300. This is very important for maintaining the overall balance and aesthetics of the tower fan 10, especially when the user adjusts the fan direction or moves the tower fan 10.

[0049] In some embodiments, the tower fan body 100 is provided with a connecting member 110, the connecting member 110 is provided with a connecting protrusion 111, and the tower fan 10 further includes a stopper 400; when the tower fan 10 is in the second assembly state, the connecting protrusion 111 is penetrated through the base 300, the stopper 400 is threadedly connected to the connecting protrusion 111, and the base 300 is clamped between the stopper 400 and the connecting member 110. Among them, the connecting protrusion 111 can be a columnar component with an external thread. The stopper 400 is an annular component with an internal thread, which is used to fix the connecting protrusion 111 through a threaded connection.

[0050] During installation, the connecting protrusion 111 of the tower fan body 100 is passed through the base 300 of the base 300, and the stopper 400 is rotated to be tightened along the external thread of the connecting protrusion 111. As the stopper 400 is tightened, the base 300 is firmly clamped between the connecting member 110 and the stopper 400. When disassembly is required, the stopper 400 is screwed in the opposite direction using a suitable tool (such as a wrench or a screwdriver) to loosen the threaded connection between the stopper 400 and the connecting protrusion 111. Once the stopper 400 is loosened, the base 300 can be easily removed from the tower fan body 100.

[0051] In this way, a stable mechanical connection is formed by the cooperation of the connecting protrusion 111, the stopper 400 and the base 300, ensuring that the tower fan 10 will not loosen due to external force or vibration during use, thereby enhancing the overall stability.

[0052] In addition, the user can install or remove the connection between the tower fan body 100 and the base 300 through a simple screwing action without the need for additional tools, making the assembly process easier and faster.

[0053] In some embodiments, the connecting member 110 is provided with a plurality of first positioning portions 112, and the base 300 is provided with a plurality of third positioning portions 320, each third positioning portion 320 corresponds to a first positioning portion 112, and when the tower fan 10 is in the second combination state, each third positioning portion 320 is positioned and matched with the corresponding first positioning portion 112.

[0054] The first positioning portion 112 may be a protruding column, block or other shaped protrusion, or a corresponding groove or hole. The third positioning portion 320 may be a groove, a hole or a corresponding protrusion, and is used to match the first positioning portion 112 on the connecting member 110 .

[0055] In this way, the cooperation between the first positioning portion 112 and the third positioning portion 320 ensures that the tower fan body 100 and the base 300 can be accurately aligned during assembly. This avoids problems of instability or unsightliness caused by misalignment.

[0056] In addition, the cooperation between the first positioning portion 112 and the third positioning portion 320 not only helps to maintain the correct positional relationship between the components, but also prevents relative movement caused by external forces during use. This can significantly improve the stability and durability of the entire tower fan 10 structure.

[0057] Moreover, when the user assembles the tower fan 10, the installation can be quickly completed by visually aligning the first positioning portion 112 with the third positioning portion 320. This method reduces the possibility of incorrect installation and does not require additional tools or complex operating steps.

[0058] In some embodiments, the base 300 is provided with reinforcing ribs 320, and the reinforcing ribs 320 are located on the side of the base 300 facing away from the tower fan body 100. Among them, the reinforcing ribs 320 can be convex strip structures and are evenly distributed along the edge or inside of the base 300. The reinforcing ribs 320 can be designed in a straight line shape, a cross shape or other geometric shapes, and the specific layout can be optimized according to the size and shape of the base 300.

[0059] In this way, the reinforcing ribs 320 increase the rigidity and anti-deformation ability of the base 300, making the base 300 more stable when bearing the weight of the tower fan body 100 and not prone to bending or deformation.

[0060] In addition, the reinforcing ribs 320 help to disperse the pressure transmitted from the tower fan body 100 to the base 300, reduce local stress concentration, thereby improving the stability of the entire tower fan 10 and preventing the tower fan 10 from tipping over due to external forces during use.

[0061] Moreover, by increasing the strength and rigidity of the base 300, wear and damage caused by long-term use are reduced, and the overall service life of the tower fan 10 is extended.

[0062] In some embodiments, the height of the tower fan body 100 is greater than the height of the heightening base 200.

[0063] In this way, by setting the height of the tower fan body 100 to be greater than the height of the heightening base 200, the user can choose whether to use the heightening base 200 according to actual needs. This provides two different height options: one is the lower height when only the tower fan body 100 and the base 300 are used, and the other is the higher height after adding the heightening base 200. This enables the tower fan 10 to meet the needs of users of different heights.

[0064] In addition, the option of different heights enables users to adjust according to their own comfort levels, ensuring that the panel and air outlet of the tower fan body 100 are in the optimal positions, thus enhancing the convenience and comfort of use.

[0065] In some embodiments, the interior of the tower fan body 100 should be reasonably arranged to accommodate key components such as the wind wheel, motor, control circuit, etc. The air inlet of the tower fan 10 is usually located on the side of the tower fan body 100 to suck in air. The air outlet of the tower fan 10 is located on the side of the tower fan body 100 to blow the air in the desired direction.
