[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a bladeless fan adapter for a blower, comprising a first fan housing 1 and a second fan housing 2. The inner sides of the first fan housing 1 and the second fan housing 2 are fixedly snapped together. The fixed snap-fit ​​method can ensure the stability of the connection between the two housings, and at the same time facilitates later disassembly and maintenance, ensuring the protective effect of the housing on the internal components. The inner walls of the first fan housing 1 and the second fan housing 2 are fixedly connected to the fan body 3, which is the core power component of the adapter. The fixed connection to the inner walls of the two housings can prevent displacement during operation and ensure the stability of air delivery. A rear cover 4 is movably snapped between one end of the first fan housing 1 and the second fan housing 2. The movably snapped rear cover 4 facilitates opening to inspect or replace the internal fan body 3 and other components, taking into account both sealing and maintainability.

[0019] Reference Figure 1 , Figure 3 and Figure 4A connector sleeve 5 is movably snapped between the other ends of the first fan housing 1 and the second fan housing 2. The connector sleeve 5 serves as a transition component connecting the housing and the bladeless fan adapter 6. Its movable snap-fit ​​design allows for flexible disassembly and adjustment according to assembly requirements. The bladeless fan adapter 6 is movably sleeved on the outer end of the connector sleeve 5. This movable sleeve allows the bladeless fan adapter 6 to rotate around the connector sleeve 5, flexibly adjusting the airflow direction of the air outlet 7 and improving usability. An air outlet 7 is provided on the outer edge of the front of the bladeless fan adapter 6. Multiple air outlets 7, evenly spaced in a ring, allow for uniform airflow diffusion, expanding the airflow range and improving the user experience of bladeless fan supply. Multiple air outlets 7 are provided and evenly spaced in a ring. An assembly component 8 is provided between the fan adapter 6 and the connector sleeve 5. This assembly component 8 is the core connection structure between the two, used to achieve quick positioning and assembly, and a secure connection to ensure it does not loosen during use. The assembly component 8 includes an assembly pin 81, an assembly slot 83, and an assembly base 84, which work together to form a snap-fit ​​assembly structure. Through mechanical cooperation, the adapter 6 and the connector sleeve 5 can be detachably fixed. The structure is simple and reliable. The outer wall of the assembly pin 81 is fixedly connected to the outer wall of the connector sleeve 5, providing a fixed fulcrum for the connection and ensuring accurate positioning during assembly. Two assembly pins 81 are provided, mirror-imaged along the central axis of the connector sleeve 5. The two assembly pins 81 ensure even force distribution, preventing loosening due to unilateral stress and improving assembly stability. A telescopic pin 82 is fixedly connected to the outer wall of each assembly pin 81. The telescopic pin 82, with its elastic telescopic function, is a key component for quick engagement and disengagement between the assembly pin 81 and the assembly seat 84. The outer wall of the telescopic end of the telescopic pin 82 movably engages with the inner wall of the assembly seat 84. This movable engagement between the telescopic pin 82 and the assembly seat 84 allows for quick and easy assembly and fixing of the adapter and connector sleeve 5. An assembly slot 83 is located on the outer wall of the bladeless fan adapter 6, providing a channel for the insertion of the assembly pin 81. Its dimensions are compatible with the assembly pin 81, ensuring proper assembly. The assembly slots 83 are provided in two ways. The two assembly slots 83 are mirror images of the bladeless fan adapter 6 along the central axis, matching the mirror image of the assembly pin 81. This ensures that the two can be accurately aligned during assembly, improving assembly efficiency and accuracy. The outer wall of the assembly bracket 84 is fixedly connected to the bladeless fan adapter 6. The assembly bracket 84 and the bladeless fan adapter 6 are fixedly connected, providing a locking support point for the telescopic locking pin 82, forming a stable locking structure. There are two sets of assembly brackets 84, and the two sets of assembly brackets 84 are mirror images of the two assembly slots 83 respectively. Each set of assembly brackets 84 corresponds to one assembly slot 83. The mirror image setting can make the force received by the locking pin symmetrical, further enhancing the overall stability after assembly.

[0020] Working principle: First, the first fan housing 1 and the second fan housing 2 are fixedly connected on the inside to form a complete outer shell. The fan body 3, which is fixed on the inner wall, is stably housed inside as the core power component. Then, the rear cover 4 is movably connected to one end of the housing to ensure both sealing and ease of maintenance. At the same time, the connector sleeve 5 is movably connected to the other end of the housing as a transition piece connecting the housing and the bladeless fan adapter 6. Next, the assembly of the bladeless fan adapter 6 and the connector sleeve 5 is completed with the help of the assembly component 8: the two assembly pins 81, which are mirror images of the outer wall of the connector sleeve 5 along the central axis, are inserted into the assembly slots 83 that are mirror images of the outer wall of the bladeless fan adapter 6. At this time, the telescopic pins 82 on the assembly pins 81 will elastically extend and retract and lock into the inner wall of the assembly seat 84 set in the corresponding assembly slot 83 on the bladeless fan adapter 6, so as to achieve a quick and stable connection between the two. When the equipment is started, the main body of the fan 3 operates to generate airflow. The airflow is transported to the connector sleeve 5 through the internal channel formed by the first fan housing 1 and the second fan housing 2, and then introduced into the bladeless fan adapter 6. Finally, it is evenly diffused and sent out through multiple air outlets 7 distributed at equal intervals in a ring on the outer edge of the front of the adapter. This not only expands the air supply range, but also ensures the stability of the air supply. The fixed snap-fit ​​and movable snap-fit ​​structural designs adopted by each component not only ensure the connection stability during operation, but also take into account the convenience of later maintenance.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
