Such spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figure experiences a position flip or a change in attitude or a change in state of motion, then the indications of these directivities correspondingly change, for example: an element described as "under" or "beneath" another element or feature would then be oriented "over" or "above" the other element or feature. Accordingly, the example term "below … …" may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used herein interpreted accordingly.

As shown in fig. 1 to 6, in a first aspect, an embodiment of the present application provides a function key, including: the device comprises an outer shell 10, a pressing assembly 20 and a functional assembly 30, wherein the outer shell 10 is provided with a cylinder wall 11, a sliding space 12 is formed in an inner cavity of the cylinder wall 11, and a first clamping piece 111 is arranged at the end part of the cylinder wall 11; the pressing assembly 20 comprises a pressing structure 21 and a sealing structure 22, the pressing structure 21 is movably positioned in the sliding space 12, the sealing structure 22 is coated on the periphery outer side of the cylinder wall 11, and the sealing structure 22 is contacted with the first clamping piece 111; the functional component 30 is provided with a pressing structure 31, the functional component 30 is detachably connected with the outer shell 10, and the pressing structure 31 presses the sealing structure 22 against the first clamping piece 111.

Through seal structure 22 cladding in the week outside of section of thick bamboo wall 11 for steam invasion needs the steering of more than one hundred eighty degrees, can reduce the possibility of steam invasion through the route setting, and the detachable connection of the functional module 30 of the cooperation makes to support and presses structure 31 can support and push away seal structure 22 and first fastener 111 and offset and form sealedly, thereby realizes further steam isolation, and such setting makes the function button also can prevent effectively that liquid or steam from invading when facing moist external environment. The application effectively solves the problem of poor waterproof performance of the functional keys in the prior art when facing complex outdoor environments.

It should be noted that, through the setting of seal structure 22 with pressing structure 21 and trigger structure 32 separation, and then the position of pressing structure 21 even take place the phenomenon of liquid seepage, waterproof demand that satisfies to such setting has been solved the restriction to pressing structure 21, pressing structure 21 can set up according to actual pressing feel, also can avoid the manufacturing of meticulous part, and then reduced manufacturing cost, solved the function button among the prior art can not satisfy waterproof, pressing feel and manufacturing cost requirement simultaneously problem. The arrangement of the sliding space 12 provides a displacement space for the pressing structure 21, i.e. provides a sliding arrangement of the pressing structure 21, and the sliding space 12 may be a linear cavity adapted to the pressing structure 21, which is more beneficial for sliding the pressing structure 21. The trigger structure 32 is positioned as a trigger structure 32 having a reset function, which enables resetting of the trigger structure 32 as well as the pressing structure 21 after pressing. Further, the mechanism used for resetting is a linear spring, the pressing structure 21 is reset by pushing against the triggering structure 32, and when no external force acts, the gravity of the pressing structure 21 does not compress the linear spring, and the non-triggering state is maintained.

In the solution of the present embodiment (not shown in the figures), the sealing structure 22 is made of a flexible material. Such arrangement is advantageous for effectively deforming and sealing the inside of the functional key, since the pressing structure 21 is of a dynamic structure, the conventional hard sealing member, such as packing, felt, etc., is adopted, which interferes with the pressing structure 21 during use, which affects the pressing feel of the pressing structure 21, and the assembly process and sealing capability are relatively limited in such low-pressure air, which can play a role in sealing. The flexible material, such as silica gel, rubber and other materials, can adapt to the dynamic process of the pressing structure 21 on one hand, and has good recovery effect after the flexible material is deformed on the other hand, plays a certain reset effect, and is more beneficial to the use of the functional keys.
