[0004] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme:

[0005] One aspect of the present application provides a key intermediate for mounting on a printed circuit board, comprising a main body portion, a connecting portion and a folded portion connected in sequence, the folded portion being arranged opposite to the main body portion, and a slot for embedding one end of the printed circuit board being formed between the main body portion, the connecting portion and the folded portion.

[0040] The technical solutions of the present application will be described clearly and completely below in conjunction with the drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0041] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0042] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0043] In the related art, the key structure module has many material pieces, including a printed circuit board, a key support, key silica gel, a key, and a decoration piece. The key and the key support are sequentially mounted into the decoration piece, then the key silica gel is mounted into the key support, and finally the decoration piece with the key is mounted with the printed circuit board. Due to structural limitations, the key support and the key silica gel structure cannot be completely prevented from being installed in reverse and have small visual differences. In the production process, the support and the silica gel are easily installed in reverse. In addition, the key silica gel is too thin and is easily detached during the transfer process after being mounted into the key support, which affects the efficiency.

[0044] As shown in Figures 1 to 7 One aspect of the present application provides a key intermediate 04 for mounting on a printed circuit board 08, which includes a main body part 03, a connecting part 06, and a folding part 05 connected in sequence. The folding part 05 is arranged opposite to the main body part 03, and a slot 07 is formed between the main body part 03, the connecting part 06, and the folding part 05 for embedding one end of the printed circuit board.

[0045] The key intermediate 04 provided by the present application, when connected with the printed circuit board 08, is inserted with the printed circuit board 08 through the slot 07. The connecting part 06 can limit the relative position of the key intermediate 04 and the printed circuit board 08 in the direction parallel to the printed circuit board 08, and the main body part 03 and the connecting part 06 can limit the relative position of the key intermediate 04 and the printed circuit board 08 in the direction perpendicular to the printed circuit board 08. This makes it difficult to separate the key intermediate 04 and the printed circuit board 08 during production, thereby achieving the purpose of preventing the key intermediate 04 from falling off during the key structure module process and improving the assembly efficiency of the key structure module. Moreover, since the key intermediate 04 is inserted with the printed circuit board 08, rather than being mounted on the support first and then mounted on the printed circuit board 08 through the support, the support material piece is removed, which not only reduces the production cost but also further improves the production efficiency due to the reduction of assembly steps. At the same time, since the insertion direction between the slot 07 and the printed circuit board 08 is determined, the problem of installation in reverse is unlikely to occur without the anti-falling structure, which reduces the probability of incorrect installation during assembly and further improves the assembly efficiency.

[0046] As shown in Figures 2 to 4As shown in one or more embodiments, the main body 03 has a fitting surface 11, the connecting portion 06 is located at the edge of the fitting surface 11, and the slot opening of the slot 07 is directed to the middle of the fitting surface 11. The connecting portion 06 is arranged at the edge of the fitting surface 11 to avoid the middle of the fitting surface 11 as much as possible, and the connecting portion 06 has enough area to interact with the printed circuit board 08. The slot opening of the slot 07 is directed to the middle of the fitting surface 11, so that the printed circuit board 08 can have a larger interaction area with the fitting surface 11 after the printed circuit board 08 is inserted into the slot 07. Of course, the connecting portion 06 can also be arranged near the middle of the fitting surface 11.

[0047] In one or more embodiments, the connecting portion 06 is in the shape of a strip, and the extending direction of the folding portion 05 corresponds to the extending direction of the edge of the fitting surface 11. This makes the connecting portion 06 have a longer length, and increases the limiting range of the connecting portion 06 to the printed circuit board 08. Of course, the connecting portion 06 can also be in the shape of a block structure such as a circle or a square.

[0048] As shown in one or more embodiments, the connecting portion 06 is in the shape of a strip, and the extending direction of the folding portion 05 corresponds to the extending direction of the edge of the fitting surface 11. This makes the connecting portion 06 have a longer length, and increases the limiting range of the connecting portion 06 to the printed circuit board 08. Of course, the connecting portion 06 can also be in the shape of a block structure such as a circle or a square. Figure 4 and Figure 5 As shown in one or more embodiments, the connecting portion 06 is in the shape of a U. This makes the connecting portion 06 have a longer length, and increases the limiting range of the connecting portion 06 to the printed circuit board 08. On the other hand, the connecting portion 06 can limit the printed circuit board 08 from multiple directions parallel to the printed circuit board 08, and has better limiting ability to the printed circuit board 08. Of course, the connecting portion 06 can also be in the shape of an L, or in a multi-segment distribution structure.

[0049] In one or more embodiments, the folding portion 05 is in the shape of a strip. This makes the folding portion 05 have a longer length, and increases the limiting range of the folding portion 05 to the printed circuit board 08.

[0050] In one or more embodiments, the turn-up portion 05 is U-shaped, and the extension direction of the turn-up portion 05 corresponds to the extension direction of the edge of the fitting surface 11. This makes the turn-up portion 05 have a larger length, and the turn-up portion 05 can contact the printed circuit board 08 in a larger area, thereby better defining the relative position of the key intermediate piece 04 and the printed circuit board 08 in the direction perpendicular to the printed circuit board 08. Of course, the turn-up portion 05 can also be a plate-shaped structure covering the middle part of the fitting surface 11, but when the printed circuit board 08 is inserted into the slot 07, the plate-shaped turn-up portion 05 will cover the printed circuit board 08 in a larger area, which will adversely affect the heat dissipation of the printed circuit board 08. However, the U-shaped turn-up portion 05 provided in the embodiment of the present application not only plays a limiting role on the printed circuit board 08, but also avoids most of the printed circuit board 08, thereby reducing the adverse effects of the turn-up portion 05 on the heat dissipation of the printed circuit board 08.

[0051] In one or more embodiments, the turn-up portion 05 and the connecting portion 06 are both U-shaped, and the extension trajectory of the turn-up portion 05 is the same as the extension trajectory of the connecting portion 06.

[0052] As shown in Figure 1 and Figure 3 In one or more embodiments, the key intermediate piece 04 further comprises a convex portion 02 and a plurality of key limiting posts 01, the convex portion 02 and each key limiting post 01 are located on the side of the main body portion 03 away from the turn-up portion 05, the convex portion 02 and each key limiting post 01 protrude from the main body portion 03 away from the turn-up portion 05, and each key limiting post 01 is arranged around the periphery of the convex portion 02. Preferably, each key limiting post 01 is uniformly distributed around the convex portion 02. When the atomizer is assembled, the convex portion 02 and each limiting post in the decoration part are used to contact the key, the convex portion 02 is used to trigger the switch on the printed circuit board 08, such as a tactile switch or a dome sheet, and each key limiting post 01 plays a role in limiting the position of the key, so that the key is difficult to collapse or tilt in the extension direction of the key limiting post 01. The surface of the convex portion 02 facing the printed circuit board 08 can be a groove forming a switch receiving space. In the embodiment of the present application, the convex portion 02 and the key limiting post 01 are preferably cylindrical, and correspondingly, each key limiting post 01 is uniformly distributed around the convex portion 02. Of course, the convex portion 02 can also be square.

[0053] As shown in Figure 8As shown, in one or more embodiments, a limiting step 12 is formed on the edge of the main body part 03 and recessed into the main body part 03, the limiting step 12 is located on the side of the main body part 03 away from the folding part 05, and the limiting step 12 is used to cooperate with the limiting claw 16 of the decoration part 10 to limit the freedom of the key intermediate part 04 in the direction perpendicular to the printed circuit board 08.

[0054] As shown, another aspect of the present application provides an atomizer, which comprises a printed circuit board 08 and a key intermediate part 04 provided by the embodiments of the present application, and the key intermediate part 04 is inserted into the printed circuit board 08 through the slot 07. Figures 5 to 10

[0055] The atomizer provided by the present application adopts the key intermediate part 04 provided by the present application. When the key intermediate part 04 is connected with the printed circuit board 08, the key intermediate part 04 is inserted into the printed circuit board 08 through the slot 07, the connecting part 06 can limit the relative position of the key intermediate part 04 and the printed circuit board 08 in the direction parallel to the printed circuit board 08, and the main body part 03 and the connecting part 06 can limit the relative position of the key intermediate part 04 and the printed circuit board 08 in the direction perpendicular to the printed circuit board 08, so that the key intermediate part 04 and the printed circuit board 08 are not easy to separate during the production process, and the key intermediate part 04 is not easy to fall off during the process of assembling the key structure module, thereby improving the assembly efficiency of the key structure module. Moreover, since the key intermediate part 04 is inserted into the printed circuit board 08, rather than being installed on the bracket first and then being installed on the printed circuit board 08 through the bracket, the bracket is removed, which not only reduces the production cost, but also further improves the production efficiency due to the reduction of the assembly steps. At the same time, since the insertion direction between the slot 07 and the printed circuit board 08 is determined, the problem of being installed in reverse is not easy to occur without setting the foolproof structure, which reduces the probability of wrong assembly during the assembly process, and further improves the assembly efficiency. In the embodiments of the present application, the distance between the folding part 05 and the main body part 03 in the slot 07 is not greater than the thickness of the printed circuit board 08. When the key intermediate part 04 is made of elastic materials such as silica gel, the folding part 05 and the main body part 03 are in pressure contact with the printed circuit board 08 inserted into the slot 07, thereby improving the limiting effect on the printed circuit board 08.

[0056] ​In one or more embodiments, the atomizer further comprises a key cap 09, the key middle piece 04 further comprises a convex portion 02 and a plurality of key limiting posts 01, the convex portion 02 and each of the key limiting posts 01 are located on a side of the main body portion 03 away from the folded portion 05, the convex portion 02 and each of the key limiting posts 01 protrude from the main body portion 03 away from the folded portion 05, and the convex portion 02 and each of the key limiting posts 01 abut against the key cap 09. It can be understood that the atomizer in the embodiments of the present application further comprises a decoration piece 10, when the atomizer is assembled, the convex portion 02 and each of the limiting posts in the decoration piece 10 are used to contact the key cap 09, the convex portion 02 is used to trigger the printed circuit board 08, and each of the key limiting posts 01 plays a role of limiting the position of the key cap 09, so that the key cap 09 is difficult to collapse or rise in the extension direction of the key limiting posts 01. As shown in Figure 10 The shell of the atomizer provided in the embodiments of the present application comprises the decoration piece 10 and a shell portion 17.

[0057] As shown in Figure 9 In one or more embodiments, the atomizer further comprises a decoration piece 10, a key cap mounting slot is formed on the decoration piece 10, a first flange 13 is formed on the inner wall of the key cap mounting slot, the key cap 09 comprises a key cap body 15 and a second flange 14 formed on the outer wall of the key cap body 15, the key cap mounting slot is sleeved on the key cap body 15, the key middle piece 04 and the key cap 09 are arranged in sequence in a first direction, the second flange 14 and the first flange 13 are arranged in sequence in the first direction, and the second flange 14 and the first flange 13 abut against each other in the first direction. In this way, when installing, first insert the key cap body 15 into the key cap mounting slot in the first direction, so that the second flange 14 abuts against the first flange 13, and then abut the key middle piece 04 and the key cap 09 in the first direction to limit the position of the key cap 09.

[0058] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
