Description

Technical Field

[0001] This utility model relates to the field of fan duct technology, and in particular to a detachable bladeless fan air outlet duct structure. Background Technology

[0002] Bladeless fans, with their unique design, safety features, and gentler airflow, have quickly gained popularity in the market since their introduction and are highly favored by consumers. Compared to traditional fans, bladeless fans eliminate exposed rotating blades, significantly reducing safety risks during use, making them especially suitable for homes with children or pets. Furthermore, their air multiplication technology produces a more even and gentle airflow, mimicking the effect of natural wind and providing users with a more comfortable experience.

[0003] However, bladeless fans currently on the market still have some significant drawbacks in terms of airflow duct structure. Many bladeless fans use an integrated airflow duct design, which means that the entire duct system must be assembled as a whole during production. If a component inside the duct malfunctions, repairs require disassembling the entire duct and even the fan body, making repairs extremely difficult, time-consuming, and labor-intensive, and potentially damaging the overall fan structure and reducing the product's lifespan. Furthermore, integrated ducts present numerous inconveniences during transportation. Their larger size increases the space occupied during transport, and they are more susceptible to damage from collisions during transit, increasing transportation costs and the risk of product loss.

[0004] To address these issues, some bladeless fans have begun to adopt detachable air duct structures. However, existing detachable connection methods are often overly complex, requiring the use of various additional connectors such as screws, nuts, and clips. This not only increases the number of parts and costs but also makes the actual disassembly and installation process cumbersome, requiring specialized tools and demanding a high level of user skill, which to some extent affects the user experience. Utility Model Content

[0005] The present invention aims to at least partially solve one of the problems existing in the existing related technologies. To this end, the present invention proposes a bladeless fan air outlet duct structure that is simple in structure, easy to disassemble and install, firmly connected and low in cost.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A detachable bladeless fan air outlet duct structure includes a detachably connected split pipe and an air outlet pipe. One end of the split pipe is provided with a connecting port, and one end of the air outlet pipe is connected to an insert pipe that is fitted to the connecting port. An elastic hook is provided on the inner wall of the connecting port, and a slot is provided on the outer wall of the insert pipe. After the insert pipe is inserted into the connecting port, the elastic hook is engaged in the slot.

[0007] In some embodiments, the elastic hook includes a connecting block and a hook block, the hook block being hooked into the slot, and the upper and lower walls of the hook block being inclined first guide slopes.

[0008] In some embodiments, one inner wall surface of the slot is a second guide slope that mates with the first guide slope.

[0009] In some embodiments, a guide insertion structure is provided between the connecting port and the insertion tube.

[0010] In some embodiments, the guide insertion structure includes a guide groove on the inner wall of the connecting tube, and a guide flange on the outer wall of the insertion tube that can slide into the guide groove.

[0011] In some embodiments, the guide slot has a V-shaped structure with a larger outer end and a smaller inner end.

[0012] In some embodiments, an annular groove is provided at the inner end of the connecting pipe, and a sealing ring is provided in the annular groove.

[0013] In some embodiments, an exhaust port is provided on one side of the air outlet pipe.

[0014] In some embodiments, the left and right ends of the diversion pipe are provided with connecting pipe ports, and each connecting pipe port can be detachably connected to an air outlet pipe. An air inlet pipe port is provided on one side of the diversion pipe and between the two connecting pipe ports.

[0015] In some embodiments, an arc-shaped diverter seat is provided inside the diverter pipe and between the two connecting pipe openings. The arc-shaped diverter seat is used to guide and divert the airflow entering from the air inlet pipe to the two connecting pipe openings respectively.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. The splitter pipe and outlet pipe of this structure are detachably connected via a combination of elastic hooks and slots. This design offers significant advantages in the production process. During assembly on the production line, workers can quickly insert the pipe into the connecting port without the need for complex tools, ensuring the elastic hooks accurately engage with the slots to complete the duct assembly, greatly improving production efficiency. When a duct malfunction occurs during use, users or maintenance personnel can easily separate the splitter pipe from the outlet pipe, quickly locate and address the faulty component, and reassemble it rapidly after repair. This effectively reduces maintenance difficulty and cost, shortens the product maintenance cycle, and improves product availability and lifespan.

[0017] 2. The connection between the flexible hook and the slot provides a stable and reliable connection between the splitter pipe and the outlet pipe; the flexible hook tightly hooks into the slot, ensuring that the splitter pipe and the outlet pipe will not loosen or separate due to vibration or airflow impact, maintaining the integrity and sealing of the air duct system, ensuring the stable and efficient operation of the fan, providing users with a continuous stable and powerful airflow effect, and improving the user experience.

[0018] 3. The detachable duct structure greatly facilitates the transportation and storage of bladeless fans. During transportation, the splitter pipe and outlet pipe can be disassembled and packaged separately, significantly reducing the overall size of the product, minimizing space occupation during transport, and reducing transportation costs. In terms of product storage, the disassembled duct components can be placed more compactly, saving warehouse space and improving warehouse management efficiency. Attached Figure Description

[0025] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0026] like Figures 1-6 The detachable bladeless fan air duct structure shown includes a detachably connected split pipe 1 and an air outlet pipe 2. One end of the split pipe 1 is provided with a connecting port 3, and one end of the air outlet pipe 2 is connected to an insert pipe 4 that is assembled with the connecting port 3. An elastic hook 5 is provided on the inner wall of the connecting port 3, and a slot 6 is provided on the outer wall of the insert pipe 4. After the insert pipe 4 is inserted into the connecting port 3, the elastic hook 5 is hooked into the slot 6.

[0027] In actual production, the diversion pipe 1 and the air outlet pipe 2 can be manufactured using plastic injection molding, which facilitates mass production and ensures dimensional accuracy; the dimensions of the connecting pipe port 3 and the insert pipe 4 must strictly follow the design standards to ensure a tight fit; the elastic hook 5 can be integrally injection molded with the connecting pipe port 3, and the material is selected as plastic with certain elasticity and strength, while the slot 6 is directly formed on the outer wall of the insert pipe 4 through a mold; of course, the number of elastic hooks 5 and slots 6 is preferably two sets, and the two sets are symmetrically arranged.

[0028] When it is necessary to connect the split pipe 1 and the air outlet pipe 2, insert the tube 4 into the connecting pipe port 3. As the tube 4 is inserted, the outer wall of the tube 4 presses against the elastic hook 5, causing it to deform elastically. When the slot 6 moves to the position of the elastic hook 5, the elastic hook 5 quickly rebounds under its own elastic force and hooks into the slot 6, thus achieving a firm connection between the split pipe 1 and the air outlet pipe 2. When disassembling, simply apply a certain external force to make the elastic hook 5 deform again and disengage from the slot 6, and the tube 4 can be pulled out from the connecting pipe port 3.

[0029] This detachable connection method greatly simplifies the assembly and disassembly process of the bladeless fan's air outlet duct. In the production stage, it improves assembly efficiency; in later maintenance, it facilitates cleaning of the duct or replacement of parts, reducing maintenance costs. Simultaneously, the cooperation between the elastic hooks and the slots ensures the stability of the connection, preventing the duct from separating due to vibration or other reasons during fan operation, thus ensuring stable airflow.

[0030] See Figure 2 , Figure 3 , Figure 6As shown, the elastic hook 5 includes a connecting block 21 and a hook block 22. The hook block 22 is hooked into the slot 6, and the upper and lower walls of the hook block 22 are both inclined first guide slopes 23.

[0031] During the process of inserting the cannula 4 into the connecting tube port 3, the outer wall of the cannula 4 first contacts the first guide slope 23 of the hook block 22. Due to the inclined setting of the first guide slope 23, the insertion force of the cannula 4 will be decomposed into a force that deforms the elastic hook 5 and a force that pushes the hook block 22 to move along the axis of the cannula 4. As the cannula 4 goes deeper, the elastic hook 5 gradually deforms. When the slot 6 reaches the position of the hook block 22, the connecting block 21 rebounds, and the hook block 22 is smoothly inserted into the slot 6 under the action of the first guide slope.

[0032] Furthermore, one inner wall surface of the slot 6 is a second guide slope 31 that cooperates with the first guide slope 23.

[0033] When the insertion tube 4 is inserted into the connecting tube port 3, the first guide slope 23 of the hook block 22 and the second guide slope 31 of the slot port 6 abut against each other, further enhancing the stability of the connection part.

[0034] When the insertion tube 4 needs to be pulled out of the connecting tube port 3, the elastic hook 5 can be easily deformed by the cooperation of the first guide slope 23 and the second guide slope 31, which facilitates the disassembly of the air outlet tube 2.

[0035] In this invention, a guide insertion structure is provided between the connecting port 3 and the insertion tube 4.

[0036] Furthermore, the guide insertion structure includes a guide groove 51 provided on the inner side wall of the connecting pipe port 3, and a guide flange 52 provided on the outer side wall of the insertion tube 4 that can slide into the guide groove 51.

[0037] The guide groove 51 and the guide flange 52 can be formed simultaneously during the manufacturing of the connecting tube 3 and the insert 4. The depth and width of the guide groove 51 are designed according to the size of the insert 4 and the guiding accuracy required during insertion. The size of the guide flange 52 is adapted to the guide groove 51 to ensure smooth sliding within the guide groove.

[0038] During the process of inserting the tube 4 into the connecting tube port 3, the guide flange 52 slides along the direction of the guide groove 51; the guide groove 51 provides a precise insertion path for the guide flange 52, so that the tube 4 can be accurately inserted into the connecting tube port 3, avoiding the tube 4 from shifting or tilting during the insertion process, thereby ensuring that the elastic hook 5 can be smoothly aligned with the slot 6 and complete the connection.

[0039] Furthermore, the guide groove 51 has a V-shaped structure with a larger outer end and a smaller inner end.

[0040] Since the guide groove 51 is V-shaped, the larger opening at the outer end allows the guide flange 52 to enter smoothly. As the insertion tube goes deeper, the guide flange 52 gradually moves inward under the guidance of the V-shaped guide groove 51. During the movement, the V-shaped structure generates a certain clamping force on the guide flange 52, further ensuring that the insertion tube 4 is inserted in the correct direction.

[0041] Of course, it is preferable to have two sets of guide slots 51 and guide flanges 52, and the two sets are symmetrically arranged, which further enhances the guiding accuracy and stability of the guide insertion structure.

[0042] See Figure 5 , Figure 6 As shown, an annular groove 71 is provided at the inner end of the connecting pipe 3, and a sealing ring 72 is provided in the annular groove 71.

[0043] When the insert 4 is inserted into the connecting pipe 3, the sealing ring 72 is located in the gap between the connecting pipe 3 and the insert 4. During the operation of the fan, the airflow in the duct will generate a certain pressure. Under the action of pressure, the sealing ring 72 undergoes elastic deformation and tightly fits between the connecting pipe 3 and the insert 4, thereby effectively preventing airflow from leaking from the connection and ensuring the airtightness of the duct system.

[0044] In this invention, an exhaust port 80 is provided on one side of the air outlet pipe 2. During the operation of the fan, the airflow is discharged through the exhaust port 80.

[0045] In this utility model, both the left and right ends of the diversion pipe 1 are provided with connecting pipe ports 3, and each connecting pipe port 3 can be detachably connected to an air outlet pipe 2. An air inlet pipe port 81 is provided on one side of the diversion pipe 1 and between the two connecting pipe ports 3.

[0046] The airflow generated by the bladeless fan base enters the split pipe through the air inlet 3. Inside the split pipe 1, the airflow is split and flows to the connecting pipes 3 at the left and right ends respectively. Since both ends of the split pipe 1 are connected to the air outlet 2, the airflow passes through the connection between the connecting pipe 3 and the air outlet 2 and is finally discharged from the air outlet 2, thus realizing the fan's air outlet function.

[0047] Furthermore, an arc-shaped diversion seat 91 is provided inside the diversion pipe 1 and between the two connecting pipe ports 3. The arc-shaped diversion seat 91 is used to guide the airflow entering from the air inlet 81 to the two connecting pipe ports 3 respectively.

[0048] When the airflow enters the splitter pipe 1 from the air inlet 3, it directly impacts the arc-shaped splitter seat 91. Due to the special shape of the arc-shaped splitter seat 91, the airflow is divided into two parts, which are guided along the curved surface of the arc-shaped splitter seat 91 to the connecting pipes 3 on the left and right sides respectively. The arc-shaped splitter seat 91 can effectively change the direction of the airflow, so that the airflow is evenly distributed to the two connecting pipes 3, avoiding the turbulence and collision of the airflow in the splitter pipe 1.

[0049] The arc-shaped diverter seat 91 improves the airflow diversion effect in the diverter pipe 1, ensuring the uniformity and stability of the airflow from the left and right air outlet pipes 2; it also reduces the energy loss of the airflow during the diversion process and improves the airflow efficiency of the fan.

The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
