Description

Technical Field

[0001] This utility model relates to the field of home appliance technology, specifically to a control component and device. Background Technology

[0002] Most household appliances have their buttons or control panels located on the appliance itself, such as refrigerators, rice cookers, and humidifiers. With the increasing prevalence of smart technology and the growing number of functions in appliances, the number of buttons has increased, and the user interfaces have become more complex. For smaller appliances, the focus is on smaller size and a simpler appearance, leading to a wide variety of button designs. Some are partitioned, increasing the difficulty of operation, while others have a separate remote control, which is inconvenient to store and often requires searching for. For appliances involving liquids, such as humidifiers, aroma diffusers, and rice cookers, placing buttons and control panels on the appliance body also presents the problem of liquid and gas erosion of the circuit boards.

[0003] Nowadays, the focus of home appliances is mainly on functionality and aesthetics, with little attention paid to operation and usability. For example, the aroma diffuser with patent number ZL202222545727.0 and the aroma humidifier with patent number ZL202120325689.0 both have control panels located on the body. When cleaning or when liquid leaks, the control panels are easily soaked in liquid. Moreover, the control panels are located at the bottom or facing downwards of the body, requiring users to bend down or place the product at or above eye level to see them clearly. Utility Model Content

[0008] Furthermore, the opening of the receiving cavity is in the shape of a circular bottle mouth, a first protrusion is provided on the front cover surrounding the opening, and a second protrusion is provided on the rear cover surrounding the opening; the top cover is in the shape of a circular bottle cap, and at least two snap-fit ​​structures are provided on the inner surface of the side wall of the top cover to engage with the first protrusion and / or the second protrusion.

[0009] Preferably, there are two buckle structures, which are arranged opposite to each other on the inner surface of the side wall of the top cover.

[0010] Furthermore, each of the inner walls of the front and rear covers has at least one mounting position. The potentiometer is fixed to the inner wall of the receiving cavity through the mounting position. The rotating shaft of the potentiometer extends from the opening of the receiving cavity and is fixedly connected to the insertion hole provided on the top cover. Rotating the top cover causes the rotating shaft to rotate accordingly, thereby adjusting the potentiometer.

[0011] Furthermore, the fastener is a tubular channel that opens onto the outer surface of the rear cover and extends into the receiving cavity. The fastener also provides some limiting and support for the components located within the receiving cavity.

[0012] Preferably, the inner diameter of the fastener gradually decreases along the extension direction.

[0014] A device includes a body and the aforementioned control components; the body is provided with at least one connector that mates with the fasteners, thereby detachably mounting the control components onto the body.

[0015] Furthermore, a first window is provided on the body, and when the control component is connected to the body via a connecting cable, the connecting cable enters and exits the body through the first window.

[0016] Furthermore, the equipment includes humidifiers, aroma diffusers, etc.

[0017] The beneficial effects of this utility model are: The control component of this utility model has a simple structure. By combining the positional design of each component, each part is fully utilized, minimizing the number of parts used. For example, the potentiometer also serves as a support for the front cover, rear cover, and top cover; and the top cover, for instance, serves as a fixing component for the front and rear covers while also functioning as an adjustment knob for the potentiometer.

[0018] The control component of this invention is an independent module that can be used independently of the equipment or assembled into the equipment as part of it. Whether used independently or assembled, the control component is isolated from the equipment body, unaffected by vapor or liquid, and as an independent module, it is also more convenient to disassemble and maintain.

[0019] The device of this invention achieves simple assembly through connecting parts (such as connecting columns) and fasteners, resulting in an integrated design and high installation efficiency.

[0031] See Figures 1 to 4 The control component 200 of this utility model includes a front cover 210, a rear cover 220, a top cover 230, a PCB control board 240, and a potentiometer 250. The front cover 210 and the rear cover 220 are detachably connected to form a receiving cavity with an opening; The top cover 230 is detachably connected to the front cover 210 and the rear cover 220 at the opening of the receiving cavity; The PCB control board 240 and the potentiometer 250 are located within the receiving cavity; At least one fastener 221 is provided on the rear cover 220 for assembling the control component 200 onto other devices.

[0032] In some embodiments, the front cover 210 and the rear cover 220 can be detachably connected by a snap fastener 232; the front cover 210 is provided with a male snap fastener 225 (or a female snap fastener 211), and the rear cover 220 is provided with a female snap fastener 211 (or a male snap fastener 225). The front cover 210 and the rear cover 220 are joined together by the connection of the male snap fastener 225 and the female snap fastener 211 to form a receiving cavity with an opening at the top.

[0033] See Figure 4In some embodiments, a second window 222 is provided on the rear cover 220. When the control component 200 is connected to the controlled device via a connecting line (not shown in the figure), the connecting line enters and exits the receiving cavity through the second window 222.

[0034] One end of the connecting cable outside the receiving cavity can be fitted with an adapter (not shown in the figure). When the control component 200 is assembled and used with other devices, the connecting cable is connected to the connecting cable of the controlled device through the adapter. When the control component 200 needs to be separated from the controlled device, the adapter can be disconnected.

[0035] In some embodiments, the rear cover 220 is further provided with at least one vent 223 to help the control component 200 dissipate heat.

[0036] See Figures 1 to 5 In some embodiments, the opening of the receiving cavity is formed by the front cover 210 and the rear cover 220. The opening is preferably in the shape of a circular bottle mouth. The front cover 210 forming the opening is provided with a first protrusion 212, and the rear cover 220 forming the opening is provided with a second protrusion 224. The top cover 230 is in the shape of a circular bottle cap and is adapted to the circular bottle mouth-shaped opening. The inner surface of the side wall of the top cover 230 is provided with at least two snap-fit ​​structures 232, which are engaged with the first protrusion 212 and / or the second protrusion 224.

[0037] In some preferred embodiments, the number of the snap-fit ​​structures 232 is two, arranged opposite each other on the inner surface of the side wall of the top cover 230. This balances the use of less material and the stability of the connection between the top cover 230 and the front cover 210 and the rear cover 220.

[0038] In some embodiments, at least one mounting position 226 is provided on the inner wall of each of the front cover 210 and the rear cover 220. The potentiometer 250 is fixed to the inner wall of the receiving cavity through the mounting position 226. The rotating shaft 251 of the potentiometer 250 extends from the opening of the receiving cavity and is fixedly connected to the insertion hole 233 provided on the top cover 230. When the top cover 230 is rotated, the rotating shaft 251 rotates accordingly, adjusting the potentiometer 250. The potentiometer 250 has at least one fixing point on the inner surface of the front cover 210 and the rear cover 220, which not only fixes the potentiometer 250, but also provides a supporting force to the front cover 210 and the rear cover 220, making the connection between the front cover 210 and the rear cover 220 more secure; the rotating shaft 251 of the potentiometer 250 also provides support for the top cover 230.

[0039] In some embodiments, the fastener 221 is a tubular channel that opens onto the outer surface of the rear cover 220 and extends into the receiving cavity. The fastener 221 also provides a certain degree of limiting and supporting for the components located within the receiving cavity, which can reduce the number of parts used for fixing and limiting. For example, it can reduce the range of movement of the PCB control board 240 within the receiving cavity, and can even adjust the extension length of the fastener 221 within the receiving cavity to directly lock the PCB control board 240 in a certain position.

[0040] In a preferred embodiment, the inner diameter of the fastener 221 gradually decreases along its extension direction. This design allows the connection to tighten automatically when a mating connector is inserted into the channel of the fastener 221, eliminating the need for additional tightening components.

[0041] In some embodiments, the operation buttons or operation interface of the control component 200 are disposed on the outer surface of the front cover 210 for easy operation.

[0042] See Figures 6 to 7 This utility model also provides a solution for applying the control component 200 to household appliances. Such appliances include a body 100 and the aforementioned control component 200 of this utility model; the body 100 is provided with at least one connector, which matches the fastener 221, so that the control component 200 can be detachably installed on the body 100.

[0043] In some embodiments, the body 100 has a first window 112. When the control component 200 is connected to the body 100 via a connecting line (not shown in the figure), the connecting line enters and exits the body 100 through the first window 112. An adapter (not shown in the figure) can also be installed at the end of the connecting line outside the body 100, connecting it to an adapter on the connecting line located outside the receiving cavity of the control component 200. When it is necessary to separate from the control component 200, the adapter can be unplugged, making connection and disassembly very convenient.

[0044] In some embodiments, the device includes a humidifier, an aroma diffuser, etc. The body 100 of the humidifier, aroma diffuser, etc., usually uses or generates liquids or mist. Using the control component 200 of this utility model, dry and wet separation can be achieved, reducing the corrosive damage of liquids and mists to the control component 200.

[0045] The control component 200 of this utility model has a simple structure. By combining the positional relationship of each component, each part is fully utilized, minimizing the number of parts used. For example, the potentiometer 250 also serves as a support for the front cover 210, rear cover 220, and top cover 230; and the top cover 230 serves as a fixing part for the front cover 210 and rear cover 220, while also functioning as an adjustment knob for the potentiometer 250.

[0046] The control component 200 of this invention is an independent module that can be used independently of the equipment or assembled into the equipment as part of it. Whether used independently or assembled, the control component 200 is isolated from the body 100 of the equipment and is not affected by gas or liquid. As an independent module, it is also more convenient to disassemble and maintain.

[0047] The device of this utility model achieves simple assembly through the connecting parts (such as connecting columns 110, etc.) and fasteners 221 of the body 100, with an integrated design and high installation efficiency. The body 100 and the control components 200 are separated, making cleaning and maintenance more convenient.

[0048] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
