Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0021] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0022] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0023] In the description of the present utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "arrangement", "installation", "connection" and "coupling" shall be understood in a broad sense. For example, the connection may be a fixed connection, a detachable connection, or an integrated connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, which means the connection between the interiors of the two elements. A person skilled in the art can understand the specific meanings of the above terms in the present utility model according to specific situations.

[0024] In the related art, for the first device and the second device to implement the linkage function, they usually need to be products from the same brand manufacturer, so as to ensure the consistency of communication protocols. However, this limits the independent selection right of users to a certain extent, that is, when the user only has the first device of brand A, he has to purchase the second device of the same brand to implement the linkage function. With the solution in the embodiment of the present utility model, when the user only has the first device of brand A, the user can choose the second device of brand B, and the manufacturer of brand B provides the knob assembly in the embodiment of the present utility model for the user through gift or tie-in sale. Since the knob assembly in the embodiment of the present utility model can know the operating state of the first device of brand A, and can send the corresponding operating state to the second device of brand B through the communication module, thus enabling users to implement the cross-brand device linkage function without replacing the first device of brand A, which greatly enhances the independent selection right of users and improves the use experience of products.

[0025] Some embodiments of the present utility model are described in detail below with reference to the accompanying drawings. In case of no conflict, the embodiments and the features in the embodiments described below can be combined with each other.

[0026] Example 1 An embodiment of the present utility model provides a knob with a battery, comprising: a knob body 1; the knob body 1 is coupled to a corresponding first device; the knob body 1 comprises an induction module and a communication module; the communication module is in communication connection with a corresponding second device; the knob body 1 is provided with a battery compartment, and a battery compartment cover 141 is arranged on the battery compartment; the battery compartment is used for placing a battery that supplies power to the induction module and the communication module; the induction module is used for acquiring the operating state of the first device and sending the operating state to the communication module; the communication module is used for sending the operating state to the second device, so that the second device makes a response based on the operating state.

[0027] Specifically, the knob body 1 is coupled to the valve stem of the first device. The knob body 1 and the valve stem can rotate synchronously around the axis of the valve stem. A battery compartment for placing a battery is provided inside the knob body 1. An opening is provided on the knob body 1, which is connected to the battery compartment. The battery can be placed in the battery compartment through the opening. The battery compartment is provided with a battery compartment cover 141. The battery compartment cover 141 is generally part of the housing of the knob body 1 and is provided at the opening to close the opening.

[0028] Both the sensing module and the communication module are located inside the knob body 1. The communication module follows the same communication protocol as the communicator of the second device. After the knob is powered on, the communication module pairs with the second device to achieve data communication. The sensing module can directly transmit data with the first device to obtain the operating status of the first device and send the obtained sensing signal to the communication module. The communication module forwards the operating status of the first device to the second device with which it has been paired. The second device responds according to the operating status of the first device. For example, if the second device learns that the first device is powered on, the second device will also power on synchronously; if the second device learns that the first device is powered off, the second device will also power off synchronously. Those skilled in the art will understand that the power-off state and the power-on state are the most basic operating states of household appliances such as stoves, range hoods, dishwashers, steam ovens, and air conditioners. Therefore, the knob in this embodiment can at least realize the linkage of the opening and closing functions between the first device and the second device.

[0029] The communication module is not limited to using Bluetooth, WIFI or other communication solutions; it only needs to enable wireless linkage for data transmission between two devices.

[0030] Furthermore, in some preferred embodiments of this utility model, the knob body 1 includes: a knob upper cover 11 and a knob lower cover 12, with an installation cavity provided between the knob upper cover 11 and the knob lower cover 12; a circuit board 5 is provided in the installation cavity; a battery compartment cover 141 is provided on the knob lower cover 12, the battery compartment is provided in the installation cavity and connected to the knob lower cover 12; a positive electrode spring 143 and a negative electrode spring 142 are provided on the circuit board 5 corresponding to the position of the battery compartment.

[0031] For details, see Figure 1The schematic diagram shown in this embodiment of the present invention provides a structural diagram of a knob body 1. The knob body 1 includes an upper knob cover 11 and a lower knob cover 12. The upper knob cover 11 and the lower knob cover 12 are fixedly connected by a connector (e.g., a bolt passes through a bolt hole 122 for fixed connection). There is a mounting cavity between the two, in which the sensing module and the communication module are placed. The battery compartment cover 141 is part of the lower knob cover 12. The user can remove the knob body 1 and open the battery compartment cover 141 to replace the battery. By placing the battery compartment cover 141 on the lower knob cover 12, the battery compartment cover 141 is not exposed after the knob body 1 is installed, making the knob more aesthetically pleasing and safer. When the user needs to replace the battery, the knob body 1 can be removed.

[0032] See Figure 2 The schematic diagram of a battery compartment structure provided in the present utility model embodiment shows that a circuit board 5 is provided in the mounting cavity between the upper cover 11 and the lower cover 12 of the knob. One end of the positive electrode spring 143 and one end of the negative electrode spring 142 are both connected to the circuit board 5, and the other ends are respectively connected to the positive and negative terminals of the battery installed in the battery compartment.

[0033] Furthermore, in some preferred embodiments of this utility model, the knob further includes: a rotating core 4; a first slot 13 is provided on the knob body 1, and a plurality of limiting grooves 131 are provided circumferentially in the first slot 13; the rotating core 4 is provided with a protrusion 41 and a valve stem groove 42; the protrusion 41 is provided on the outer surface of the rotating core 4; the protrusion 41 can be selectively inserted into any limiting groove 131, and the protrusion 41 can restrict the rotation of the rotating core 4 through the limiting groove 131; the valve stem groove 42 is provided with a limiting surface 421, the valve stem groove 42 is inserted into the valve stem of the first device, and the valve stem of the first device is restricted to rotate in the valve stem groove 42 through the limiting surface 421.

[0034] Specifically, a first slot 13 is provided at the center of the lower cover 12 of the knob body 1; see also Figure 3 The figure shown is a bottom view of a knob cover according to an embodiment of the present invention. Multiple limiting grooves 131 are provided circumferentially within the first slot 13; see also... Figure 4 The schematic diagram of the rotating core provided in this embodiment of the present invention is shown. The rotating core 4 in this embodiment is provided with three protrusions 41. However, in actual production, there is no restriction on the number and shape of the protrusions 41. As long as they can be selectively inserted into any limiting groove 131, a relatively fixed positional relationship can be formed with the knob cover 12 of the button body or the knob body 1 with an integrated design.

[0035] Taking a dual-burner gas stove as an example, see Figure 5The schematic diagram shown in this embodiment of the present invention illustrates the effect of replacing the existing knobs in a dual-burner gas stove. The initial positions of the two old knobs, which are also the positions indicating the device is off on the device surface, usually point in the same direction. However, the limiting surfaces on the two valve stems on which the knobs are installed are usually mirrored. If the existing knobs are replaced, the initial position of the installed knobs is unlikely to point to the position indicating the device is off.

[0036] See Figure 6 The diagram shown illustrates the interaction between the rotating core and the knob body in this embodiment of the invention. Three interaction methods (a, b, and c) are shown, each with a different angle between the limiting surface 421 and the initial knob marking. The valve stem groove 42 is provided with a limiting surface 421. The valve stem groove 42 is inserted into the valve stem of the first device, and the limiting surface 421 restricts the rotation of the valve stem within the valve stem groove 42. It is understood that after the knob is installed, the base position on the knob body 1 will differ due to the different angles of the limiting surface 421, thus achieving adjustment of the knob installation angle. Interaction methods b and c perfectly solve the problem of… Figure 5 The problem with the device shown is that the left and right valve stems are installed in the manner shown in b and c respectively, so that the initial position of the replaced knob is exactly the same as the initial direction of the original knob.

[0037] Furthermore, in some preferred embodiments of this utility model, the knob further includes: a base 2; the base 2 is provided with a sensing element 22; the sensing module includes: a sensing sensor; the sensing sensor can rotate synchronously with the rotation of the knob body 1; the base 2 is fixedly mounted on the first device; the sensing module is used to detect the sensing element 22 through the sensing sensor to generate a sensing signal, and send the sensing signal to the communication module; wherein, during the rotation of the knob body 1, the sensing signal can switch between a first signal and a second signal; the first signal indicates that the first device is in a power-off state; the second signal indicates that the first device is in a power-on state; the communication module is also used to send the sensing signal to the second device so that the second device responds based on the sensing signal.

[0038] For details, see Figure 7The schematic diagram of a base provided in this embodiment of the present invention shows that a through hole 21 slightly larger than the diameter of the valve stem is provided in the center of the fixed base 2. The valve stem passes through the through hole 21. A sensing element 22 is fixedly installed on the base 2. The sensing sensor can generate a sensing signal based on the sensing element 22. The sensing signal changes with the distance between the two. The sensing sensor is fixedly installed in the button body and can rotate synchronously with the knob body 1. The first signal indicates that the first device is in the off state. After the knob is installed, when the first device is in the off state, the signal at this time is taken as the first signal. Generally, the signal strength is recorded. In some preferred embodiments of the present invention, due to some installation errors, the first signal can be set as a signal strength range. As long as the strength of the sensing signal falls within this range, it means that the sensing signal at this time is the first signal. Based on this, sensing signals with strength greater than or less than the first signal are collectively referred to as the second signal. In some preferred embodiments of the present invention, the first signal is usually the sensing signal with the strongest signal strength. At this time, the sensing element 22 and the sensing sensor are closest.

[0039] The sensing sensor can be any device that can detect the rotational position of the knob body 1, such as a magnetic sensor, mechanical switch, or infrared sensor.

[0040] The sensing sensor sends the acquired sensing signal to the communication module, which then forwards the signal to the paired second device. The second device responds based on the sensing signal; for example, if the second device learns that the first device is powered on, the second device also powers on simultaneously; conversely, if the second device learns that the first device is powered off, the second device also powers off simultaneously. Those skilled in the art will understand that the power-off state indicated by the first signal and the power-on state indicated by the second signal are the most basic operating states possessed by household appliances such as stoves, range hoods, dishwashers, steam ovens, and air conditioners. Therefore, the knob in this embodiment can at least achieve the linkage of the on / off functions between the first and second devices.

[0041] Furthermore, in some preferred embodiments of this utility model, the sensing element 22 is a sensing rod; a second slot 121 is provided on the knob body 1; the sensing rod is inserted into the second slot 121, and the second slot 121 constitutes a groove space that limits the rotation range of the knob body 1. During the rotation of the knob body 1, the second slot 121 rotates with the knob body 1 and is displaced relative to the sensing rod.

[0042] For details, please refer to [link / reference]. Figure 7 The sensor 22 is fixedly mounted on the side of the base 2 opposite to the main body of the button assembly; see also Figure 8The illustration shows a bottom view of a knob body provided in this embodiment of the present invention. The second slot 121 is arc-shaped and partially surrounds the first slot 13. It is understood that the sensor 22 is inserted into the second slot 121. During the rotation of the knob body 1, the sensor 22 moves within the second slot 121. When the sensing rod abuts one end of the second slot 121 during the rotation of the knob body 1, the knob body 1 can no longer continue rotating in the current direction. The sensing sensor is disposed within the mounting cavity, close to the groove wall of the second slot 121. In some preferred embodiments of the present invention, the sensing sensor is attached to the groove wall of the second slot 121, which allows for more sensitive detection of the sensor 22.

[0043] Furthermore, in some preferred embodiments of this utility model, the knob further includes: an indicator light; the indicator light is disposed on the circuit board 5; a viewing window 111 is disposed on the knob body 1 corresponding to the position of the indicator light; an indicator mark 23 is disposed on the base 2; when the sensing signal is the first signal, the indicator mark 23 and the indicator light are positioned at the same location.

[0044] Specifically, in this embodiment, all components in the knob assembly are mounted on the circuit board 5; the indicator light can be a single-color light or a multi-color light, reflecting different working states of the knob through color changes or different display formats; correspondingly, the knob body 1 can be transparent or semi-transparent. For example, when the sensing signal is the first signal, the indicator light is off; when the sensing signal is the second signal, the indicator light is constantly on; furthermore, when the indicator light flashes regularly, it indicates that the knob is in pairing mode and can be paired with a second device.

[0045] The position of the viewing window 111 is not limited; the user only needs to be able to observe the indicator light through the viewing window 111. If the material of the knob body 1 is opaque, the viewing window 111 can be transparent or it can be an opening; see [link / reference]. Figure 9 The diagram shown is a schematic of the position of a window provided in an embodiment of the present invention. The window 111 is disposed on the knob cover 11.

[0046] See also Figure 7 The indicator mark 23 usually functions when the knob is installed. It is aligned with the reference position of the old switch button when the first device is in a certain working state, usually the position of the off state. After the base 2 is installed on the surface of the first device, when the knob body 1 is installed, the position of the indicator light (i.e. the window 111) is aligned with the position of the indicator mark 23. At this time, the sensing signal sensed by the sensor is the first signal.

[0047] Furthermore, in some preferred embodiments of this utility model, the communication module is a Bluetooth module or a WiFi module.

[0048] Specifically, the communication module can be set as a Bluetooth module, which features low power consumption, fast transmission, and does not rely on an external network, enabling communication anytime. The knob can be powered by button batteries, various dry cell batteries, or rechargeable batteries, which can save internal space and facilitate replacement; furthermore, wireless power supply can also be integrated.

[0049] Furthermore, in some preferred embodiments of this utility model, the sensing element 22 is a magnet; the sensing sensor is a Hall sensor, a mechanical switch, or an infrared sensing sensor.

[0050] Specifically, the sensing sensor can be a Hall sensor, which features fast response time, low temperature drift, high accuracy, small size, wide bandwidth, strong anti-interference ability, and strong overload capacity, making it suitable for kitchens.

[0052] Example 2 Based on the above embodiments, this utility model provides another knob, which is set on the stove and can obtain the working status of the stove and send it to the range hood; after purchasing a range hood with stove-range linkage, the user can replace the original knob on the stove with this knob and achieve stove-range linkage without replacing the stove.

The operating status is then sent to the electrical equipment linked to the home appliance via the communication module. This allows for device linkage without replacing a large number of electrical devices, greatly improving the user experience.
