Description

Technical Field

[0001] The utility model relates to the technical field of waterproof structures, and particularly relates to a knob with double waterproof functions. Background Art

[0002] At present, water dispensers and water purifiers on the market are generally equipped with heating or instant heating technologies to meet users' daily needs for hot water. However, since everyone has different preferences for the temperature of hot water or warm water, the traditional fixed heat preservation temperature setting is difficult to meet the expectations of all users. Therefore, many water dispensers and water purifiers have introduced temperature adjustment functions, allowing users to set the temperature according to their own preferences to achieve a personalized drinking experience.

[0003] Among the various modes of interaction between electronic devices and users, including buttons / keys, knobs, touch controls, voice controls, and remote controls, for the adjustment of specific numerical values such as temperature, stepless adjustment technology provides the most accurate and flexible solution. In particular, achieving stepless adjustment through a knob is not only intuitive and easy to understand but also extremely convenient to operate, making it one of the most popular interaction methods among users. For example, the document with the publication number CN209694925U provides a temperature adjustment device for a water dispenser, using a knob as the interaction structure to adjust the water outlet temperature of the water dispenser. The document with the publication number CN210810550U also provides a warning water dispenser that is convenient for maintenance and has an anti-scald mechanism, and a knob is also used as the adjustment interaction structure in this solution. In both solutions, the knobs are respectively arranged above and below the water outlet of the water dispenser. However, when the water outlet of the water dispenser outputs hot water, especially boiling water, a large amount of water vapor will be generated. When the user finishes receiving water, a small amount or a large amount of water often leaks from the water outlet. The accumulated water in the water receiving tray assembly is also likely to overflow, and finally, the accumulated water or water vapor seeps into the interior of the water dispenser body along the gap between the knob and the knob installation position, resulting in adverse phenomena such as electric leakage and corrosion of the circuit board. Summary of the Invention

[0004] Aiming at the problems in the related technologies, the utility model provides a knob with double waterproof functions, which has better waterproof and waterproof vapor performance.

[0005] The utility model is realized as follows:

[0006] A knob with double waterproof functions is arranged on a shell. An installation opening is provided on the surface of the shell, and an electronic control unit is arranged inside the shell. It includes a rotating part and a connecting part. The rotating part includes a connecting portion and a sleeving portion. The connecting portion extends outward along the top of the circumference and is folded to form the sleeving portion. The groove formed between the sleeving portion and the connecting portion faces the installation opening.

[0007] The connecting member is an annular cylindrical structure, which is arranged between the rotating member and the mounting port; the connecting member and the mounting port are fixedly connected; a first sealing member is connected between the outer peripheral side of the connecting member and the sleeve portion; a second sealing member is connected between the outer peripheral side of the connecting member and the mounting port; the bottom of the connecting portion passes through the connecting member and is connected with the electronic control unit.

[0008] After installation, the rotating part shields the lower connecting parts, the installation opening, and the circuit mechanism and complex structure inside the installation opening.

[0009] The outward-turned portion of the rotating part is used to cover the installation port, electrical and other structures below, and the connecting part is used to assist the connection between the rotating part and the installation port; there is a clearance fit between the rotating part and the connecting part, and between the connecting part and the installation port. By setting the first seal and the second seal, the sealing of the connection can be improved to form a double waterproof knob structure to prevent water or water vapor from penetrating into the interior of the installation port along the gap.

[0010] The first sealing member and the second sealing member are both silicone sealing rings, or other solid rubber materials with elasticity, strong sealing and waterproof properties.

[0011] The electronic control unit is a circuit board, on which a rotatable stepless or step-adjustable encoder is provided. The encoder is fixedly connected to a rotating member, and the rotation of the rotating member acts on the encoder.

[0012] As a further optimization of the above solution, a first limiting groove and a second limiting groove are respectively provided along the outer peripheral side of the connecting member; the first limiting groove cooperates with the first sealing member; and the second limiting groove cooperates with the second sealing member.

[0013] The first limiting groove and the second limiting groove are used for fixing and limiting the first sealing member and the second sealing member respectively.

[0014] As a further optimization of the above scheme, the connecting member is raised along the outer peripheral side of the top to form a limiting step; after the knob is installed, the limiting step is limited to the outside of the installation port; the outer peripheral side of the limiting step is connected to the first sealing member; the outer peripheral side of the connecting member is connected to the second sealing member outside the limiting step.

[0015] The limiting convex step is used to limit the installation depth of the connector at the installation opening to avoid over-embedding and facilitate installation.

[0016] As a further optimization of the above solution, an outwardly protruding fixing portion is provided at the bottom of the outer peripheral side of the connecting member; the connecting member forms a fixing groove between the limiting convex step and the fixing portion; and the fixing groove cooperates with the installation opening.

[0017] The setting of the fixing part and the formation of the fixing groove effectively improve the fastening and stability of the fit between the connecting piece and the mounting opening.

[0018] Furthermore, the end of the fixing part is provided with a first inclined surface facing outward; a second inclined surface is provided at the mounting opening; the first inclined surface and the second inclined surface cooperate with each other to assist in guiding the installation of the connector at the mounting opening. The inclined surface can also be replaced with a rounded corner, an arc surface, etc.

[0019] As a further optimization of the above solution, a plurality of evenly distributed, plate-shaped deformation parts are formed by the axial protrusion of the bottom edge of the connecting piece; the fixing part is provided at the bottom of the outer side of the deformation part.

[0020] When the connecting piece is installed, the bottom faces the mounting opening and is inserted. After the deformation part is set, the fixing part drives the deformation part to be squeezed and deformed towards the middle until the mounting opening cooperates with the fixing groove, and the deformation part and the fixing part return to their original positions. Compared with directly setting on the connecting part, setting the deformation part can not only maintain good elastic changes but also ensure the structural strength of the connecting part itself.

[0021] As a further optimization of the above solution, a plurality of deformation joints are provided on the connecting piece; the deformation joints extend vertically from the bottom edge of the connecting piece and are arranged on both sides of the deformation part.

[0022] The setting of the deformation joints enables the deformation part to have better elastic deformation characteristics.

[0023] As a further optimization of the above solution, the surface of the housing is smoothly arranged around the mounting opening.

[0024] Furthermore, a glass panel is installed on the surface of the housing, and the glass panel is provided with an opening equal in size to the mounting opening at the mounting opening. The glass panel is convenient for users to clean.

[0025] As a further optimization of the above solution, a first annular platform protruding outward is provided along the edge of the mounting opening;

[0026] or a second annular platform protruding vertically towards the inside of the housing is provided along the edge of the mounting opening;

[0027] or the first annular platform and the second annular platform are provided simultaneously.

[0028] Both the first annular platform and the second annular platform are part of the mounting opening.

[0029] The surface of the housing is smoothly arranged, such as a plane, etc. Compared with setting the first annular platform, each has its own advantages. Among them, the former housing is convenient for production, and the appearance line is smooth and beautiful; the latter model has high production difficulty and high cost, but it is more convenient for gap sealing and has better waterproof effect.

[0030] As a further optimization of the above solution, a limiting rib is provided on the outer peripheral side of the connecting member, and a limiting groove is provided at the edge of the mounting opening; the limiting rib and the limiting groove cooperate with each other.

[0031] The arrangement of the limiting rib and the limiting groove further improves the fastening property after the connecting member is installed.

[0032] As a further optimization of the above solution, after the knob is installed, there is a gap between the bottom of the groove and the top of the connecting member; there is a gap between the end of the socket part and the surface of the housing.

[0033] Preferably, the connecting member can also be used as a decorative member. The separately arranged connecting member and the outer sides of the housing and / or the rotating member are respectively provided with different colors, so that the device provided with the knob has a more beautiful appearance and can meet the customized needs of users. The connecting member, the housing and / or the rotating member can also be respectively made of different materials.
