[0050] 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.

[0051] With the improvement of people's living standards, many traditional household appliances can no longer meet the usage needs of users. Therefore, more and more household appliances are improved on the basis of the original equipment, and the air purifier is one of them. At present, when installing the various components of the adapter adapter board of the air purifier, it is necessary to connect the various parts of the adapter adapter board into one body through additional components such as screws. The above operation method makes the assembly efficiency of the adapter adapter board relatively low, and at the same time, installing with screws is likely to cause a certain degree of damage to the drilled parts of the adapter adapter board.

[0052] Therefore, the technical problem to be solved by the present invention is that when installing the various components of the adapter adapter board of the air purifier in the prior art, the installation efficiency is relatively low and it is easy to cause damage to the drilled parts, thereby providing an adapter adapter board and an air purifier.

[0053] Embodiment 1

[0054] As Figures 1 to 7 shown, the embodiment of the present invention provides an adapter adapter board, which includes a first wire pressing member 1 and a second wire pressing member 2, and a buckling structure for connecting the first wire pressing member 1 and the second wire pressing member 2.

[0055] Specifically, as Figures 1 to 5 shown, an adapter socket 3 is provided on the first wire pressing member 1. AsFigure 1 , Figure 2 , Figure 3 and Figure 6 As shown in Figure 6 , when the second wire pressing member 2 is connected to the first wire pressing member 1 through a fastening structure, the first side plate 12 and the bottom plate 11 of the first wire pressing member 1 and the accommodating portion 22 of the second wire pressing member 2 surround to form an installation cavity suitable for installing the circuit board 4, and the circuit board 4 is electrically connected to the adapter base 3. The fastening structure can be a buckle 15 provided on the first wire pressing member 1 and a slot 25 provided on the second wire pressing member 2, or a slot 25 provided on the first wire pressing member 1 and a buckle 15 provided on the second wire pressing member 2.

[0056] Of course, those skilled in the art can change the positions and quantities of the buckle 15 and the slot 25 according to the actual situation, as long as the first wire pressing member 1 and the second wire pressing member 2 can be connected through structural cooperation. At the same time, those skilled in the art can also change the fastening structure according to the actual situation. This embodiment is only an example and is not restrictive, as long as the same technical effect can be achieved.

[0057] In the embodiment of the present invention, the first wire pressing member 1 and the second wire pressing member 2 are directly connected through structural cooperation by setting a fastening structure, without connecting the various parts of the adapter adapter board into one body through additional components such as screws. There is no need for work processes such as screwing during installation, thereby improving the installation efficiency. At the same time, it can also avoid a certain degree of damage to the various parts of the adapter adapter board caused by the drilling parts formed during screw installation.

[0058] In some embodiments of the present invention, the first wire pressing member 1 includes a bottom plate 11, a first side plate 12, and a second side plate 13. As Figures 2 to 4 shown, the bottom plate 11 has two opposite end faces. An adapter base 3 is provided on the first end face, and a buckle 15 is provided on the second end face opposite to the first end face. The buckle 15 extends in a direction away from the adapter base 3. At the end of the bottom plate 11 away from the adapter base 3, as Figure 3 shown, that is, a convex plate 14 is provided at the rightmost end of the bottom plate 11. The first side plate 12 is provided on the upper side of the bottom plate 11, and the first side plate 12 connects the upper side of the bottom plate 11 and the upper side of the convex plate 14 at the same time. The second side plate 13 is provided on the other side of the convex plate 14, as Figure 3 shown, that is, on the lower side of the convex plate 14. Both the first side plate 12 and the second side plate 13 are provided at a certain angle with the bottom plate 11 and extend in a direction away from the adapter base 3, so that the first side plate 12, the second side plate 13, and the convex plate 14 surround to form a wire routing groove, and a part of the side wall of the installation cavity is surrounded by the first side plate 12 and the bottom plate 11.

[0059] As Figure 3 and Figure 4As shown, a through hole 16 is also provided on the bottom plate 11, and the through hole 16 is arranged adjacent to the buckle 15. After the first crimping member 1 and the second crimping member 2 are installed through the buckle structure, if you want to separate the first crimping member 1 from the second crimping member 2, you can directly put your finger into the through hole 16 and apply pressure to the buckle 15, so that the first crimping member 1 and the second crimping member 2 can be separated. This makes it easy to disassemble the wiring board assembly, and replace or repair the circuit board 4 in the installation cavity, which can further improve the work efficiency of the staff.

[0060] In the embodiment of the present invention, screw holes may be provided on the first side plate 12 or the bottom plate 11 to facilitate fixing the circuit board 4 in the installation cavity. Of course, this embodiment is only an example of the installation method of the circuit board 4 and is not limiting. Those skilled in the art may fix the circuit board 4 in the installation cavity by other means, such as by gluing with silicone, as long as the same technical effect can be achieved.

[0061] In some embodiments of the present invention, Figure 6 and Figure 7 As shown, the second wire pressing member 2 includes a wire routing portion 21 and a receiving portion 22. The wire routing portion 21 and the receiving portion 22 are arranged in a stepped manner. Figure 6 For example, the upper left portion is the wiring portion 21, and the lower right portion is the accommodation portion 22. The wiring portion 21 and the accommodation portion 22 are connected via a connecting plate.

[0062] Specifically, the wiring portion 21 is composed of a plurality of side panels connected to each other, and a certain angle is set between each side panel, so that the wiring portion 21 is groove-shaped. A baffle 23 is set at the end of the wiring portion 21 away from the accommodating portion 22. When the first crimping member 1 and the second crimping member 2 are engaged with each other, the baffle 23 can just be abutted against the first side panel 12, and the wiring portion 21 and the wiring groove are engaged with each other to form a wiring cavity, and the wiring cavity is connected to the installation cavity. The wiring cavity is used to place the connecting wire 7, and the connecting wire 7 is electrically connected to the adapter seat 3. Figure 6 and Figure 7 As shown, the receiving portion 22 is composed of two side panels, which are arranged at a certain angle, and the two side panels of the receiving portion 22 surround the remaining side walls of the installation cavity. Figure 6 and Figure 7 As shown, a card slot 25 is provided inside the accommodating portion 22, and the other end of the card slot 25 is connected to the outside.

[0063] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, a first limiting protrusion 17 is provided on the bottom plate 11, and the first limiting protrusion 17 extends in a direction away from the adapter seat 3. Figure 6As shown, the receiving portion 22 is provided with a first limiting groove 24 that cooperates with the first limiting protrusion 17. The first limiting groove 24 is adapted for the first limiting protrusion 17 to be inserted therein, and the first limiting groove 24 and the first limiting protrusion 17 are in an interference fit.

[0064] Those skilled in the art can change the positions and numbers of the first limiting protrusion 17 and the first limiting groove 24 according to the actual situation. This embodiment is only for illustration and is not restrictive, as long as the same technical effects can be achieved. With such a setting, the stability between the first wire pressing member 1 and the second wire pressing member 2 during connection can be further increased, ensuring the normal operation of the adapter adapter board.

[0065] In some embodiments of the present invention, as Figure 3 and Figure 5 shown, the first wire pressing member 1 is further provided with a bottom baffle 18, which is arranged at one end of the bottom plate 11 close to the adapter base 3. The bottom baffle 18 is connected to the first side plate 12 and the bottom plate 11 at the same time, and the bottom baffle 18 constitutes the bottom sealing plate of the installation cavity. A through hole 19 is also provided on the bottom baffle 18. As Figure 6 and Figure 7 shown, the second wire pressing member 2 is provided with a limiting rib 26 at one end of the receiving portion 22 away from the wire routing portion 21. The limiting rib 26 is adapted to be inserted into the through hole 19. Thus, the stability between the receiving portion 22 and the bottom baffle 18 can be ensured.

[0066] In some embodiments of the present invention, as Figure 4 and Figure 5 shown, the adapter adapter board further includes a support portion 31 and a convex block 20. The top circumferential edge of the adapter base 3 is provided with the support portion 31, and the convex block 20 is arranged at one end of the bottom plate 11 close to the adapter base 3, such that the convex block 20 is located below the support portion 31. As Figure 5 shown, the support portion 31 is slightly higher than the convex block 20, such that there is a gap between the convex block 20 and the support portion 31, so that the second limiting protrusion 52 can be conveniently inserted into the gap between the convex block 20 and the support portion 31.

[0067] As Figure 2 and Figure 7 shown, at one end away from the receiving portion 22, the wire routing portion 21 is provided with a second limiting groove 27. As Figure 8 and Figure 9 shown, when the adapter adapter board is inserted into the notch 61 of the air duct bracket 6, it can ensure that the edge of the notch 61 is inserted into the second limiting groove 27. Thus, the stability between the adapter adapter board and the air duct bracket 6 and the housing 5 can be strengthened.

[0068] Embodiment 2

[0069] The present invention also provides an air purifier, which includes an adapter adapter board as described in any of the above embodiments.

[0070] As Figures 8 to 10 shown, the air purifier further includes a housing 5 and a duct bracket 6. The housing 5 includes a first support plate and a second support plate disposed opposite to each other, and the first support plate and the second support plate are vertically disposed on the housing 5. The first support plate and the second support plate are both provided with first through holes, and the two first through holes form a mounting hole 51, and the mounting hole 51 is adapted for the adapter adapter board to be inserted. As Figure 5 shown, the adapter adapter board is provided with a raised rib 181 on the circumferential edge of the bottom baffle 18, and the two support plates are provided with grooves on the end faces close to each other, and the raised rib 181 is adapted to be embedded in the grooves. The housing 5 is provided with a mounting groove 53 at the lower end of the mounting hole 51, and the mounting groove 53 is used for mounting the adapter seat 3.

[0071] When installing the adapter adapter board on the housing 5, first insert the adapter adapter board from the mounting hole 51, and then align the bottom baffle 18 at the end with the mounting hole 51 until the adapter seat 3 on the first wire pressing member 1 is completely inserted into the mounting groove 53, and at the same time, the raised rib 181 of the bottom baffle 18 also just fits into the groove. With such a setting, the adapter adapter board can be fixed on the housing 5, and the connection is directly carried out through structural cooperation, without the need to fix it with additional components such as screws. There is no need for working processes such as screwing during installation, so the installation efficiency can be improved. At the same time, the procurement of additional components such as screws can also be reduced, thereby significantly reducing the production cost.

[0072] As Figure 8 and Figure 10 shown, the mounting hole 51 is further provided with a second limiting protrusion 52. When the adapter adapter board is inserted into the mounting hole 51, the second limiting protrusion 52 is adapted to be embedded in the gap between the convex block 20 and the support portion 31, and the second limiting protrusion 52 and the gap are in an interference fit, which can further fix the adapter adapter board. With such a setting, the adapter adapter board can be fixed on the housing 5, and the connection is directly carried out through structural cooperation, without the need to fix it with additional components such as screws. There is no need for working processes such as screwing during installation, so the installation efficiency can be improved. At the same time, the procurement of additional components such as screws can also be reduced, thereby significantly reducing the production cost.

[0073] As Figure 8 and Figure 9As shown, the air duct bracket 6 is provided on the housing 5, and the air duct bracket 6 is provided with a notch 61 at the installation position of the adapter adapter plate, so that when the adapter adapter plate is completely inserted into the installation hole 51, the end of the adapter adapter plate away from the installation hole 51 can just be inserted into the notch 61. Moreover, the edge of the notch 61 can be embedded in the second limiting groove 27 of the wire routing portion 21, so as to be able to fix the end of the adapter adapter plate away from the installation hole 51 at the same time, further strengthening the stability of the adapter adapter plate installed on the housing 5. With such a setting, the adapter adapter plate can be fixed on the housing 5, and directly connected through structural cooperation, without the need to be fixed by additional components such as screws. There is no need for work processes such as screwing during installation, thus improving the installation efficiency. At the same time, it can also reduce the procurement of additional components such as screws, thereby greatly reducing the production cost.

[0074] Obviously, the above embodiments are only examples given for clear illustration, rather than limitations on the implementation manners. For ordinary workers in the field, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
