Description

Technical Field

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

[0002] As a new type of fan, bladeless fans are gradually gaining market favor due to their advantages such as no exposed blades and gentle airflow. By hiding the motor and blades inside the base, they utilize air multiplier technology to drive airflow, effectively solving the safety hazards and cleaning problems associated with traditional bladed fans.

[0003] However, existing bladeless fans have significant limitations in their structural design, especially their large size, which causes considerable inconvenience for carrying and transporting. Most bladeless fans use an integrated design for their air duct components and base, resulting in a large overall height and space occupation, making them unsuitable for home storage and portability. For example, when users are camping or storing away, traditional bladeless fans are difficult to carry or store due to their bulky size; in logistics and transportation, the integrated structure leads to low packaging space utilization, increasing transportation costs, and also makes components more susceptible to damage during handling due to collisions. Utility Model Content

[0004] The present invention aims to at least partially solve one of the problems existing in the prior art. To this end, the present invention proposes a portable, detachable bladeless fan.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A portable, detachable bladeless fan includes a fan base, a fan motor assembly disposed within the fan base, an air inlet on one side of the fan base, and an airflow outlet at the upper end of the fan base.

[0027] 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.

[0028] like Figures 1-9A portable, detachable bladeless fan is shown, comprising a fan base 1, a fan motor assembly disposed within the fan base 1, an air inlet 2 disposed on one side of the fan base 1, and an air outlet 3 disposed on the upper end of the fan base 1. A straight air duct 4 is detachably installed on the air outlet 3. An air duct bend 5 is connected to the upper end of the straight air duct 4. A diverter 6 is connected to the front end of the diverter 5. Both ends of the diverter 6 are provided with connecting ports 7. An air outlet 8 is detachably installed on both connecting ports 7. An air outlet 9 is provided on the front side of the air outlet 8.

[0029] The "detachable connection" design fundamentally solves the problem of excessive size of bladeless fans; the fan base 1 and the straight duct 4, the split pipe 6 and the air outlet pipe 8 all adopt a detachable structure, and each component can be stored independently after disassembly, greatly reducing the overall space occupied.

[0030] Demountable structures offer significant convenience for logistics and transportation. Disassembled components can be stacked and packaged, increasing packaging volume and reducing the number of vehicles required, thereby lowering logistics costs. Simultaneously, dispersed packaging reduces the risk of damage during transportation by minimizing compression between components, enhancing product safety. For manufacturers, smaller packaging volumes also facilitate warehouse storage and improve inventory turnover.

[0031] In addition, the detachable nature of each air duct component means that if a component is worn or damaged, the user can replace the corresponding component individually without scrapping the entire product. This not only reduces maintenance costs but also extends the overall service life of the product, which is in line with the concept of green environmental protection.

[0032] See Figures 2-5 As shown, the lower end of the straight duct 4 is provided with an installation end sleeve 21, and the lower end of the installation end sleeve 21 is provided with an installation ring 22. Multiple snap-fit ​​flanges 23 are provided along the circumference on the outer side wall of the installation ring 22. Multiple snap-fit ​​slots 24 that cooperate with the snap-fit ​​flanges 23 are provided on the inner side wall of the airflow outlet 3. Each snap-fit ​​slot 24 includes a vertical slot 25 and a horizontal slot 26 connected to one side of the lower end of the vertical slot 25. The snap-fit ​​flange 23 passes through the vertical slot 25 and rotates into the horizontal slot 26.

[0033] During installation, align the snap-fit ​​flange 23 of the mounting ring 22 with the vertical slot 25 of the airflow outlet 3 until the flange reaches the bottom of the vertical slot 25. Then rotate the mounting ring 22, and the snap-fit ​​flange 23 slides along the transverse slot 26 until it contacts the end limit protrusion. During disassembly, rotate the mounting ring 22 in the opposite direction to return the snap-fit ​​flange 23 to the position of the vertical slot 25, and then pull it out axially. This process requires no tools and can be completed by one person within 10 seconds.

[0034] Compared to threaded connections, the rotary snap-fit ​​structure offers higher installation efficiency and avoids the risk of thread stripping; multiple distributed snap-fit ​​flanges 23 ensure even force distribution and prevent the fan from falling off during operation.

[0035] Furthermore, an elastic limiting structure capable of positioning the mounting ring 22 is provided between the mounting ring 22 and the airflow outlet 3.

[0036] The elastic limiting structure includes a first elastic hook 41 disposed on the side wall of the mounting ring 22. The first elastic hook 41 is integrally injection molded with the mounting ring 22. A first hook groove 42 corresponding to the first elastic hook 41 is disposed on the inner side wall of the air outlet 3.

[0037] During the rotation of the mounting ring 22, the guide surface of the first elastic hook 41 contacts the inner wall of the air outlet 3 and deforms inward under radial pressure. When it rotates to the target position, the hook reaches the first hook slot 42, the radial constraint force disappears, the hook resets under its own elasticity, and the free end is embedded in the slot to form a circumferential mechanical lock. When disassembling, the rotational force applied by the user needs to overcome the elastic constraint force of the hook so that the hook deforms again and disengages from the slot.

[0038] The upper end of the mounting sleeve 21 is provided with a mounting sleeve 51, and the straight air duct 4 is inserted outside the mounting sleeve 51. The mounting sleeve 51 and the mounting sleeve 21 are integrally injection molded structures.

[0039] Furthermore, an annular groove 61 is provided at the upper end of the mounting sleeve 21 and around the mounting sleeve 51, a first sealing ring 62 is provided in the annular groove 61, and the lower end of the straight air duct 4 is inserted into the annular groove 61.

[0040] The first sealing ring 62 is compressed between the straight pipe 4 of the air duct and the annular groove 61, filling the gap between the two and playing a sealing role to prevent airflow from leaking from the connection between the straight pipe 4 of the air duct and the mounting end sleeve 21.

[0041] See Figures 6-9 As shown, one end of the air outlet pipe 8 is connected to an insert pipe 71 that is assembled with the connecting pipe port 7. A second elastic hook 72 is provided on the inner wall of the connecting pipe port 7, and a second hook groove 73 that cooperates with the second elastic hook 72 is provided on the outer wall of the insert pipe 71.

[0042] When installing the air outlet duct 8, insert the tube 71 into the connecting pipe port 7. The outer wall of the tube 71 presses against the protruding part of the second elastic hook 72, causing the spring to deform outward. When the tube 71 is in place, the hook protrusion aligns with the second hook groove 73, the spring returns to its original position, and the protrusion is locked into the groove, forming an axial and circumferential lock. At this time, the end of the tube 71 is in contact with the inner end of the connecting pipe port 7. When disassembling, simply apply a certain external force to cause the second elastic hook 72 to deform again and disengage from the second hook groove 73, and the tube 71 can be pulled out from the connecting pipe port 7.

[0043] Furthermore, a guide insertion structure is provided between the connecting port 7 and the insertion tube 71. The guide insertion structure includes a guide groove 81 provided on the inner side wall of the connecting port 7, and a guide flange 82 provided on the outer side wall of the insertion tube 71 that can slide into the guide groove 81.

[0044] The guide groove 81 and the guide flange 82 can be formed simultaneously during the manufacturing of the connecting tube 7 and the insert 71. The depth and width of the guide groove 81 are designed according to the size of the insert 71 and the guiding accuracy required during insertion. The size of the guide flange 82 is adapted to the guide groove 81 to ensure smooth sliding within the guide groove.

[0045] An annular groove 91 is provided at the inner end of the connecting pipe port 7, and a second sealing ring 92 is provided in the annular groove 91. When the insert tube 71 is inserted into the connecting pipe port 7, the second sealing ring 92 is located in the gap between the connecting pipe port 7 and the insert tube 71, thereby effectively preventing airflow from leaking from the connection part and ensuring the airtightness of the duct system.

[0046] See Figure 8 As shown, an arc-shaped diversion seat 93 is provided inside the diversion pipe 6 and between the two connecting pipe ports 7. The arc-shaped diversion seat 93 is used to guide the airflow entering from the duct bend 5 to the two connecting pipe ports 7 respectively.

[0047] The airflow generated by the bladeless fan base enters the split pipe 6 through the straight pipe 4 and the bend pipe 5 of the air duct. Under the action of the arc-shaped split seat 93, the airflow is split and flows to the connecting pipe ports 7 at the left and right ends respectively. Since both ends of the split pipe 6 are connected to the air outlet pipe 8, the airflow passes through the connection between the connecting pipe port 7 and the air outlet pipe 8 and is finally discharged from the air outlet 9 of the air outlet pipe 8, thus realizing the air outlet function of the fan.
