DETAILED DESCRIPTION

[0053] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0054] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0055] like Figure 1 - Figure 7 As shown, this embodiment provides a base assembly for a bladeless fan, including: a base structure 1 and at least one shell 2.

[0056] A head assembly is fixedly connected to the top of the base structure 1; at least one housing 2 is provided with an air inlet 12, and the housing 2 is snap-fitted to the base structure 1. By snapping the base structure 1 and the housing 2 of the bladeless fan together, it is not necessary to assemble other components beforehand when assembling the housing 2 and the base structure 1, thus eliminating many assembly steps. The housing 2 and the base structure 1 can be assembled directly by snapping them together, resulting in simple assembly steps and high assembly efficiency.

[0057] In this embodiment, there are two shells 2, and the base structure 1 is an annular structure. Each shell 2 is a semi-annular structure. When the two shells 2 are assembled with the base structure 1, they completely cover the outer surface of the base structure 1. By providing two shells 2, the shells 2 and the base structure 1 can be assembled and disassembled more conveniently, and there are no restrictions on the material of the shells 2. For example, the shells 2 can be made of plastic, which makes it easier to obtain the shells 2. As a convertible embodiment, it is also possible to have one shell 2, made of an elastic material, such as a rectangle when opened, which can be formed into an annular structure according to the shape of the base structure 1. As a convertible embodiment, it is also possible to have three or more shells 2.

[0058] In order to limit the position of the housing 2 in the axial direction, a plurality of first engaging structures are provided on the inner peripheral wall of the housing 2 and the end of the base structure 1. As an alternative embodiment, there may be only one first engaging structure.

[0059] The first engaging structure in this embodiment includes a first engaging portion provided on the lower surface of the upper end portion 3 of the base structure 1; and a second engaging portion provided on the inner circumferential wall of the housing 2, the second engaging portion being matingly connected to the first engaging portion. By providing the first engaging portion on the lower surface of the upper end portion 3 of the base structure 1 and matingly connecting with the second engaging portion on the inner circumferential wall of the housing 2, the housing 2 can be axially limited, preventing axial movement of the housing 2 and ensuring a secure assembly between the housing 2 and the base structure 1.

[0060] Specifically, the first engaging portion in this embodiment is the first engaging hole 6, and the second engaging portion is the first snap 7. The first snap 7 is provided on the inner peripheral wall of the shell 2 near the upper end side, and the first snap 7 includes: a first handle extending from the inner peripheral wall of the shell 2 toward the base structure 1; and a first hook extending upward from the end of the first handle away from the inner peripheral wall of the shell 2. As a convertible embodiment, the first engaging portion may be the first engaging groove. As a convertible embodiment, the first engaging portion may be the first snap 7, and the second engaging portion may be the first engaging hole 6 or the first engaging groove. As a convertible embodiment, the first snap 7 may be a clamping block.

[0061] The first engaging structure in this embodiment further includes: a third engaging portion disposed on the outer peripheral wall of the lower end portion 4 of the base structure 1; and a fourth engaging portion disposed on the inner peripheral wall of the housing 2, the third engaging portion and the fourth engaging portion being cooperatively connected. By providing the third engaging portion on the outer peripheral wall of the lower end portion 4 of the base structure 1 and cooperating with the fourth engaging portion on the inner peripheral wall of the housing 2, the housing 2 can be limited in the axial direction to prevent axial movement of the housing 2 without affecting the assembly of the purification component above the lower end portion 4, thereby ensuring the effective assembly of the purification component, the housing 2, and the base structure 1.

[0062] Specifically, in this embodiment, the third engaging portion is a third engaging hole 8, and the fourth engaging portion is a third snap 9. The third snap 9 is provided on the inner peripheral wall of the housing 2 near the lower end. As an alternative embodiment, the third engaging portion may be a third engaging groove. As an alternative embodiment, the third engaging portion may be a third snap 9, and the second engaging portion may be a third engaging hole 8 or a third engaging groove.

[0063] like Figure 3 As shown, the base structure 1 in this embodiment includes a main body, which is arranged between the upper and lower ends 4 of the base structure 1, and two connecting parts 5 are provided on the main body. A plurality of second snap-fit ​​structures are provided on the inner circumferential wall of the shell 2 and the connecting part 5; the second snap-fit ​​structure includes: a fifth snap-fit ​​part, which is arranged on the outer circumferential wall of the connecting part 5, a sixth snap-fit ​​part, which is arranged on both sides of the inner circumferential wall of the shell 2, and the fifth snap-fit ​​part and the sixth snap-fit ​​part are matched and connected; the second snap-fit ​​structure also includes: a seventh snap-fit ​​part, which is arranged on the side where the connecting part 5 is connected to the end; an eighth snap-fit ​​part, which is arranged on both sides of the inner circumferential wall of the shell 2, and the seventh snap-fit ​​part and the eighth snap-fit ​​part are matched and connected. By arranging a second snap-fit ​​structure on the inner circumferential wall of the shell 2 and the connecting portion 5, the assembly of the shell 2 on the base structure 1 is achieved. A snap-fit ​​portion is arranged on the outer circumferential wall of the connecting portion 5, which can limit the shell 2 in the radial direction. A snap-fit ​​portion is arranged on the side where the connecting portion 5 is connected to the end portion, which can limit the shell 2 in the circumferential direction, preventing the shell 2 from moving in the radial direction and rotating in the circumferential direction, thereby ensuring that the shell 2 is firmly assembled with the base structure 1.

[0064] In particular, when the first snap-fit ​​structure and the second snap-fit ​​structure exist at the same time, the outer shell 2 can be limited in three directions: axial, radial and circumferential. While ensuring that the outer shell 2 is more firmly assembled, the purification component on the inner side of the outer shell 2 can also be more firmly fixed to prevent the purification component from shifting between the base and the outer shell 2 during transportation. No additional components are needed to fix the purification component, which makes the disassembly and assembly of the purification component more convenient and also makes the overall structure of the bladeless fan simpler. As a convertible embodiment, it can also be a combination of any two of the two forms of the first snap-fit ​​structure and the two forms of the second snap-fit ​​structure, but at this time, the first snap-fit ​​structure and the second snap-fit ​​structure are capable of limiting the outer shell 2 in different limiting directions, such as any combination of axial + radial, axial + circumferential, and radial + circumferential snap-fit ​​structures.

[0065] As an alternative embodiment, the second engaging structure may be one. As an alternative embodiment, when there is one housing 2, there may be one connecting portion 5, or when there are three housings 2, there may be three connecting portions 5, or the number of connecting portions 5 may be the same as the number of housings 2, or there may be more connecting portions. As an alternative embodiment, the second engaging portion may include only the fifth and sixth engaging portions, or only the seventh and eighth engaging portions.

[0066] Specifically, in this embodiment, the fifth engaging portion is a groove 14, and the sixth engaging portion is a protrusion 13. As an alternative embodiment, the fifth engaging portion can be a protrusion 13, and the sixth engaging portion can be a groove 14. As an alternative embodiment, the fifth and sixth engaging portions can also be engaging holes or a combination of an engaging groove and a buckle.

[0067] Specifically, if Figure 7 As shown, the seventh engaging portion in this embodiment is the second engaging hole 10; the eighth engaging portion is the second snap 11, and the second clamping block is provided on the inner side of the protrusion 13. The second snap 11 includes: a second handle 15 extending from the inner peripheral wall of the shell 2 toward the base structure 1; and a second hook 16 extending from the end of the second handle 15 away from the inner peripheral wall of the shell 2 toward the connecting portion 5. As a convertible embodiment, the seventh engaging portion may be the second engaging groove. As a convertible embodiment, the seventh engaging portion may be the second snap 11, and the eighth engaging portion may be the second engaging hole 10 or the second engaging groove. As a convertible embodiment, the second snap 11 may be a clamping block.

[0068] In this embodiment, a handle 17 is provided on one side of the shell 2, and a clearance space is provided on the other side. When the shell 2 is assembled to the base structure 1, the handle 17 and the clearance space are arranged in cooperation to form an operating space. Specifically, the clearance space is a clearance groove 18. By arranging the handle 17 on one side of the shell 2 and the clearance space on the other side, when the shell 2 is assembled to the base structure 1, the handle 17 and the clearance space are arranged in cooperation to form an operating space. When the shell 2 needs to be disassembled, it is convenient for the human hand to be in the clearance space and the fingers can hook the handle 17, and the shell 2 can be released from the base structure 1 by prying it outward with force, which is convenient for operation. As a convertible embodiment, the handle 17 and the clearance space can be set as two or more. As a convertible embodiment, the clearance space can also be a clearance hole.

[0069] The base assembly in this embodiment also includes a filter structure 19, which is fixedly connected to the housing 2. The filter structure 19 is arranged correspondingly to the purification structure provided on the base structure 1. The purification structure is arranged at a groove 14 on the main body of the base structure 1, and the upper surface of the lower end portion 4 and the protrusion on the main body form the groove 14. By fixing the filter structure 19 to the housing 2, the housing 2 has a built-in filtering function. The corresponding arrangement of the filter structure 19 and the purification structure can also perform preliminary filtration on the air entering from the outside before it enters the purification structure, thereby improving the purification efficiency while reducing the frequency of cleaning or replacing the purification structure.

[0070] like Figure 5 As shown, the filter structure 19 in this embodiment is provided with two clamping ribs 20, both of which are provided on one side of the filter structure 19, and a limiting space that cooperates with the clamping rib 20 is provided on the inner peripheral wall of the shell 2. Specifically, the limiting space is a limiting hole 21. By providing the clamping rib 20 on the filter structure 19 and providing a limiting space that cooperates with the clamping rib 20 on the inner peripheral wall of the shell 2, the filter structure 19 can be easily assembled on the shell 2. As a convertible embodiment, it is also possible that the clamping rib 20 is provided as one or more. As a convertible embodiment, it is also possible that the limiting space is a limiting groove. As a convertible embodiment, it is also possible that the filter structure 19 is provided with a limiting hole 21, and the inner peripheral wall of the shell 2 is provided with a clamping rib 20.

[0071] The inner circumferential wall of the shell 2 in this embodiment is also provided with limiting ribs 22 corresponding to the end corners of the filter structure 19, which are suitable for clamping the end corners of the filter structure 19. By providing the limiting ribs 22 corresponding to the end corners of the filter structure 19 on the inner circumferential wall of the shell 2, the end corners of the filter structure 19 can be further clamped, ensuring the limiting of the filter structure 19, so that the filter structure 19 is more firmly set on the shell 2. As a convertible embodiment, it is also possible to not provide the limiting ribs 22, but to provide several more clamping ribs 20 to firmly fix the filter structure 19 on the inner circumferential wall of the shell 2. As a convertible embodiment, it is also possible to provide the filter structure 19 on the outer circumferential wall of the shell 2.

[0072] Specifically, the filter structure 19 in this embodiment is unfolded into a rectangle with four end corners. Four corresponding ribs are provided on the inner peripheral wall of the shell 2 to clamp the four end corners.

[0073] This embodiment also provides a bladeless fan, including the above-mentioned base assembly.

[0074] The bladeless fan in this embodiment includes a head assembly, which is located above the base assembly. The head assembly is provided with an air outlet, and the housing 2 is provided with an air inlet 12. Air enters through the air inlet 12, passes through the filter structure 19 and the purification structure, and then flows to the head assembly and is blown out through the air outlet. Because the housing 2 is snap-fitted to the base assembly, the housing 2 is easy to assemble and disassemble. Moreover, because the purification structure is fixedly connected to the base assembly and located within the housing 2, the purification structure is not assembled with other components. When the purification assembly needs to be disassembled, replaced, or cleaned, only the housing 2 needs to be removed to remove the purification assembly, thus making the product easy to use.

[0075] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
