Description

Technical Field

[0001] This utility model relates to the field of smart home technology, specifically a flame-sensing wireless transmitter. Background Technology

[0002] In modern kitchen environments, range hoods, as important smoke extraction devices, are widely used in various household and commercial stove systems. Traditional range hoods rely on manual operation or simple timer control to start and stop the fan, which cannot be intelligently adjusted according to the actual cooking conditions. When users forget to turn on the fan, it can easily cause oil fumes to spread, affecting kitchen air quality and human health. If the range hood is not turned off after the flame is extinguished, the fan will continue to run, resulting in energy waste and equipment damage.

[0003] In addition, although some existing range hoods are equipped with sensors, they mostly use mechanical or wired connections, which have problems such as slow response speed, complicated wiring, and inconvenient installation. They are difficult to meet the needs of modern kitchens for intelligence, automation, and aesthetics. At the same time, they lack the ability to monitor the flame status in real time. Therefore, it is necessary to develop a flame sensor wireless transmitter to accurately identify the flame status and achieve efficient linkage with the range hood control system through wireless communication, thereby improving the intelligence level and safety of the equipment. Utility Model Content

[0004] To address the aforementioned problems of traditional range hoods where the fan operation relies on manual user intervention or simple timer control, failing to intelligently adjust according to actual cooking conditions, and the complex wiring and inconvenient installation caused by existing mechanical or wired sensing devices, the technical solution adopted by this utility model is as follows:

[0005] A flame-sensing wireless transmitter includes a device body, the device body including a first housing, a control board disposed in the first housing, and a flame-sensing component electrically connected to the control board. The control board is provided with a wireless transmission module. The flame-sensing component is used to identify flames and transmit electrical signals to the control board, and transmits the electrical signals to the control system of a range hood through the wireless transmission module to realize the automatic start and stop of the range hood fan.

[0006] Furthermore, the flame sensing assembly includes a sensor and a connection portion connecting the sensor and the control board, wherein the connection portion is provided with wires for electrically connecting the sensor and the control board.

[0007] Furthermore, the device body also includes a second housing connected to the first housing, the second housing having a first mounting cavity for the first housing to be embedded in, and the second housing being used to fix the first housing.

[0008] Furthermore, the device body also includes a storage battery disposed within the first housing, the storage battery being electrically connected to the control board, the control board being provided with a charging module, the charging module including a charging port disposed on the control board, and the first housing being provided with a connection hole for connecting an external power source to the charging port.

[0009] Furthermore, the sensor is an infrared sensor or an ultraviolet sensor.

[0010] Furthermore, the first housing has a first extension on the side near the connection hole. When the first housing is inserted into the first mounting cavity, the first extension abuts against the bottom of the first mounting cavity, so that the connection hole is separated from the bottom of the first mounting cavity.

[0011] Furthermore, the second housing is provided with a drain port that connects the first mounting cavity and the outside of the second housing.

[0012] Furthermore, the first housing has a pressing part and a light-transmitting hole on one side, and the control board has a button opposite to the pressing part and an indicator light opposite to the light-transmitting hole.

[0013] Furthermore, the first housing is provided with a first cavity for mounting the control board and a second cavity for mounting the battery, and the connection hole communicates with the first cavity.

[0014] Furthermore, the connecting part is made of a malleable material, allowing the user to deform the connecting part and adjust the alignment of the sensor with the kitchen stove.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention connects a flame sensing component to a control board and includes a wireless transmission module on the control board. The flame recognition component can identify whether there is a flame or not, generating a corresponding electrical signal and transmitting it to the control board. The wireless transmission module on the control board then transmits the electrical signal to the range hood's control system, thereby enabling the range hood to start and stop automatically. This improves installation convenience and achieves intelligent control of the range hood. Attached Figure Description

[0025] Please see Figures 1 to 5 The flame-sensing wireless transmitter shown includes a device body 1. The device body 1 includes a first housing 2, a control board 3 disposed in the first housing 2, and a flame-sensing component 4 electrically connected to the control board 3. The control board 3 is provided with a wireless transmission module. The flame-sensing component 4 is used to identify flames and transmit electrical signals to the control board 3. The electrical signals are then transmitted to the control system of the range hood through the wireless transmission module to realize the automatic start and stop of the range hood fan.

[0026] In this invention, the control board is housed within the first housing. The flame sensing component is electrically connected to the control board, and the control board is equipped with a wireless transmission module, which may be, but is not limited to, Bluetooth, Wi-Fi, or ZigBee wireless protocols. The flame sensing component is used to identify flames and may employ infrared sensors, ultraviolet sensors, or other photoelectric sensing methods. When a flame is detected, the flame sensing component converts it into an electrical signal and transmits it to the control board. The control board then transmits the electrical signal to the range hood's control system via the wireless transmission module, thereby enabling the automatic start and stop of the range hood's fan.

[0027] In terms of installation, the use of wireless communication eliminates the need for complex wiring like traditional equipment, significantly reducing installation difficulty and cost. Installation is convenient and quick in both newly renovated and existing kitchens. Functionally, it enables intelligent control of the range hood, automatically controlling the fan's start and stop based on the actual flame status. When the user starts cooking, the flame sensor detects the flame and transmits a corresponding electrical signal to the control board, which then transmits the signal to the range hood's control system via a wireless transmission module, activating the fan. This effectively prevents cooking fumes from spreading in the kitchen, improving air quality and protecting health. When the flame goes out, the flame sensor transmits the same signal back to the control board, which then transmits it to the range hood's control system via a wireless transmission module, shutting off the fan. This avoids energy waste and unnecessary equipment wear and tear, extending the equipment's lifespan. The intelligent control of the range hood effectively improves the user experience and ease of operation.

[0028] Furthermore, the flame sensing assembly 4 includes a sensor 41 and a connection part 42 connecting the sensor 41 and the control board 3. The connection part 42 is provided with wires for electrically connecting the sensor 41 and the control board 3.

[0029] In this invention, the flame sensing component includes a sensor and a connecting part. Specifically, one end of the connecting part is connected to the sensor outside the first housing, and the other end is connected to the control board inside the first housing. The connecting part contains wires, which electrically connect the sensor and the control board. This design makes the connection between the sensor and the control board more stable and reliable. At the same time, the connecting part provides flexibility for adjusting the sensor's position. Users can adjust the sensor's position appropriately according to actual usage needs to ensure more accurate flame detection, thus improving the device's practicality and adaptability.

[0030] Furthermore, the device body 1 also includes a second housing 5 connected to the first housing 2. The second housing 5 is provided with a first mounting cavity 51 for the first housing 2 to be embedded in, and the second housing 5 is used to fix the first housing.

[0031] In this invention, the device body further includes a second housing connected to the first housing. A first mounting cavity is provided on the second housing, the shape and size of which match the first housing. The second housing serves as an intermediate connecting component, used to fix the first housing near the stove, so that the sensor can identify the flame. Specifically, the second housing is fixed to the stove panel or to a wall near the stove. The first housing is installed in the first mounting cavity of the second housing. The user can fix the second housing in a suitable position according to actual use to ensure that the sensor can effectively identify the flame on the stove, thus effectively improving the reliability and practicality of the device.

[0032] Furthermore, the device body 1 also includes a storage battery 6 disposed in the first housing 2. The storage battery 6 is electrically connected to the control board 3. The control board 3 is provided with a charging module. The charging module includes a charging port 31 disposed in the control board 3. The first housing 2 is provided with a connection hole 21 for connecting an external power source to the charging port 31.

[0033] In this invention, a storage battery is housed within the first housing of the device body. The storage battery is electrically connected to the control board, providing power to the control board. The control board is equipped with a charging module, which includes a charging port on the control board. Additionally, a connection hole is provided on the first housing, allowing an external power source to connect to the charging port and charge the storage battery. In summary, the storage battery eliminates the direct dependence on an external power source, enabling the device to operate normally even without an external power supply, greatly improving its flexibility and convenience. Furthermore, the charging module design ensures that the battery can be repeatedly charged, extending the device's lifespan and reducing operating costs.

[0034] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the connecting part 42 passes through the connecting hole 21 to connect the sensor 41 located outside the first housing 2 and the control board 3 located inside the first housing 2.

[0035] Furthermore, the sensor 41 is an infrared sensor or an ultraviolet sensor.

[0036] In this invention, the sensor is an infrared sensor or an ultraviolet sensor.

[0037] Because flames release electromagnetic radiation of different wavelengths during combustion, with infrared light being a major component, and the intensity of infrared radiation is directly related to the combustion state (such as flame size and temperature), the more intense the combustion, the higher the radiation intensity. Therefore, the sensor can identify the size and temperature of the flame using an infrared sensor, and then transmit electrical signals to the control board. The wireless transmission module then controls the start and stop of the range hood fan. Similarly, flames release ultraviolet light during combustion. Therefore, the sensor can use an ultraviolet sensor to capture the ultraviolet light released by the flame, converting the received ultraviolet photons into electrical signals. When the detected ultraviolet light intensity exceeds a threshold, it is determined to be in a "flame" state, and the wireless transmission module of the control board transmits an electrical signal to the range hood control system to control the fan to start. Conversely, when the detected ultraviolet light intensity is below the threshold, it is determined to be in a "no flame" state, and the wireless transmission module of the control board transmits a corresponding electrical signal to the range hood control system to control the fan to stop.

[0038] Furthermore, the first housing 2 is provided with a first extension 22 on the side near the connection hole 21. When the first housing 2 is embedded in the first mounting cavity 51, the first extension 22 abuts against the bottom of the first mounting cavity 51, so that the connection hole 21 is separated from the bottom of the first mounting cavity 51.

[0039] Since the second housing is fixedly connected to the range hood and used to install the first housing, kitchen fumes, dust, and other impurities may enter the first mounting cavity during daily use and then enter the interior of the first housing through the connection hole, damaging the control board and charging port. This invention addresses this by providing a first extension on the side of the first housing near the connection hole. When the first housing is inserted into the first mounting cavity of the second housing, the first extension abuts against the bottom of the first mounting cavity, thus separating the connection hole from the bottom of the first mounting cavity. This effectively prevents direct contact between the connection hole and the bottom of the first mounting cavity, preventing fumes, dust, and other impurities from entering the first mounting cavity and entering the interior of the first housing through the connection hole, thus protecting the control board and charging port. This improves the reliability and safety of the device and extends its service life.

[0040] Furthermore, the first mounting cavity 51 has a second extension 511 on its side, and the first extension 22 has a limiting hole 221 for the connecting part 42 to pass through, thus forming a receiving space 512 for accommodating the connecting part 42. When the first housing 2 is connected to the second housing 5, the second extension 511 abuts against the side of the first housing 2 to ensure a tight connection between the first housing 2 and the second housing 5. At the same time, when the connecting part 42 connects the control board 3 and the sensor 41 through the connecting hole 21, the limiting hole 221 allows the connecting part 42 to pass through and be limited and fixed, and then extends from the receiving space 512 to the outside of the second housing 5.

[0041] Furthermore, the second housing 5 is provided with a drain port 52 that connects the first mounting cavity 51 and the outside of the second housing 5.

[0042] In this invention, a drain port is provided on the second housing, which connects the first mounting cavity to the outside of the second housing, so that liquid entering the first mounting cavity can be discharged to the outside through the drain port, avoiding the accumulation of liquid in the first mounting cavity, thereby preventing liquid from damaging the electronic components inside the first housing, and further improving the waterproof performance and reliability of the device.

[0043] Furthermore, the first housing 2 is provided with a pressing part 23 and a light-transmitting hole 24 on one side, and the control board 3 is provided with a button 32 opposite to the pressing part 23 and an indicator light 33 opposite to the light-transmitting hole 24.

[0044] In this invention, a pressing part and a light-transmitting hole are provided on one side of the first housing, and a button corresponding to the pressing part and an indicator light corresponding to the light-transmitting hole are provided on the control board. The user can trigger the button by pressing the pressing part, thereby enabling the operation of the device. The light emitted by the indicator light can be transmitted to the outside through the light-transmitting hole, allowing the user to intuitively understand the working status of the device. Specifically, the button can be used to trigger the test program of the control board. When the user presses the button, the preset test program of the control board is activated, and different test results are displayed through different states of the indicator light. For example, when the indicator light is flashing rapidly, the battery is in a low-power state; when the indicator light is flashing gradually, the battery is charging; when the indicator light is flashing slowly, the sensor did not detect a flame during the test program; when the indicator light is constantly on, the sensor detected a flame during the test program. The different states of the indicator light help the user confirm the working status of the device, ensuring that the device can effectively detect flames, further improving the ease of use and reliability of the device.

[0045] Furthermore, the first housing 2 is provided with a first cavity 25 for installing the control board 3 and a second cavity 26 for installing the battery 6, and the connection hole 21 communicates with the first cavity 23.

[0046] In this invention, the first housing is internally divided into two cavities: a first cavity for mounting the control board and a second cavity for mounting the battery. Specifically, the first and second cavities are relatively independent rather than completely separated. A wiring channel for electrical connection between the battery and the control board is provided between the first and second cavities. The connection hole is connected to the first cavity. When charging is required, the first housing is pulled out of the first mounting cavity, allowing external power to enter the first cavity through the connection hole and connect to the charging port to provide power to the control board and the battery. This design allows the control board and battery to be installed in different cavities, achieving separate installation of electronic components and effectively avoiding interference between the control board and the battery. For example, the battery may generate heat during charging and discharging; separating it from the control board reduces the impact of heat on the control board's performance, improving the stability and reliability of the device.

[0047] Furthermore, the connecting part 42 is made of a malleable material, allowing the user to deform the connecting part 42 to adjust the alignment of the sensor 41 with the kitchen stove.

[0048] Since the location and layout of stoves in different kitchens may vary, the sensor may not be able to align with the stove flame, thus failing to effectively collect the infrared or ultraviolet rays emitted by the flame. In this invention, the connecting part is made of a malleable material with a certain degree of flexibility and memory. Users can bend, twist, or otherwise deform the connecting part according to actual needs, thereby adjusting the position of the sensor so that it can align with the stove flame. This improves the accuracy and reliability of flame detection, allowing the device to better adapt to various kitchen environments and enhancing its versatility and practicality.
