Automatic air exhaust system and Bluetooth wireless exhaust device

The present invention relates to an automatic air exhaust system for automatically controlling a Bluetooth wireless exhaust device to vent indoor air outside the ignition device to promote air circulation.

In home life, the application of flammable gases (such as liquefied petroleum gas, natural gas) is quite common. For example, gas stoves are common food cooking appliances. Generally, gas stoves are connected to the nozzles of gas drums through a hose. The gas is transferred to the gas burner through the hose for combustion to achieve the purpose of heating; similarly, the water heater is also commonly used as fuel for gas or natural gas.

Taking the kitchen as an example, a general kitchen will install a row of hoods above the gas stove. The range hood has a power button and a wind speed adjustment button such as high speed, medium speed and low speed. When the user uses the gas stove to cook food, it is necessary to manually turn on the power button of the range hood and switch the wind speed adjustment button by itself; however, if a large amount of oil smoke is suddenly generated during the cooking of the food, the user has taken the cooking tool with both hands. Or the seasoning or ingredients have been stained on the hand, and it is inconvenient for the user to press the wind speed adjustment button to switch to a higher wind speed, which often causes troubles in use.

In view of the inconvenience that the conventional range hood can only be operated by manual operation, the main purpose of the creation is to provide an automatic air exhaust system that can automatically adjust the exhaust speed without manual operation by the user, bringing the user convenient.

The automatic air exhaust system of the present invention comprises: an ignition device switch having an ignition state and a flameout state; a Bluetooth wireless exhaust device comprising a exhaust device and a Bluetooth transmission module, the Bluetooth transmission module setting And the flow detecting device and a flow detecting and controlling device for connecting a nozzle of a gas container to detect a flammable gas flow, the flow detecting and controlling device electrically connecting the ignition device switch and the Bluetooth wireless exhaust device The Bluetooth transmission module controls the Bluetooth wireless exhaust device according to the flammable gas flow rate when determining that the ignition device switch is in an ignition state, so that the flammable gas flow rate is proportional to the exhaust effect of the exhaust device relationship.

The creation also provides a Bluetooth wireless air exhaust device, which comprises an air exhaust device and a Bluetooth transmission module, and the Bluetooth transmission module is disposed in the air exhaust device.

According to the present invention, since the flow detecting and controlling device adjusts the exhausting effect of the Bluetooth wireless exhaust device according to the flammable gas flow rate of the nozzle opening, taking the cooking as an example, when the flow rate of the flammable gas (such as gas) is larger, The stronger the representative heat, the more soot caused. At this time, the flow detection and control device correspondingly enhances the exhaust effect of the Bluetooth wireless exhaust device, effectively discharging the kitchen fumes out of the room, and avoiding the user inhaling too much fumes. It is healthy and the user does not have to manually operate to adjust the exhaust speed, which greatly enhances the practicality and convenience of this creation.

Referring to FIG. 1, the present automatic air exhaust system includes an ignition device switch 11, a Bluetooth wireless exhaust device 12, and a flow rate detecting and controlling device 13.

The igniter switch 11 is disposed on an ignition device, and the igniter is connected to a nozzle of a gas container through a pipeline. The gas container stores a flammable gas, and the flammable gas may be liquefied petroleum gas, natural gas or Gas, etc., the gas container can be a gas drum, a gas pipeline or a natural gas pipeline. The ignition device switch 11 has an ignition state and a flameout state. When the ignition device switch 11 performs an ignition operation and is in an ignition state, the combustible gas stored in the gas container can be circulated to the ignition device through the nozzle port. To burn in the ignition device. The igniter switch 11 can be a switch for a water heater switch, a gas burner switch or other ignition device for a combustible gas. For example, the ignition device switch 11 can be a knob type gas burner switch. When the ignition device switch 11 is in a starting position, it is in a flameout state; the user can rotate the ignition device switch 11 to cause the ignition device switch 11 to leave. The starting position, and thus the ignition state, can burn a combustible gas (such as gas) that is delivered from the gas container.

The Bluetooth wireless air exhaust device 12 can be installed at the junction between indoors and outdoors to discharge indoor air to the outside to promote indoor air circulation. The Bluetooth wireless air exhaust device 12 includes an air exhaust device 121 and a Bluetooth transmission module 122. The air exhaust device 121 can be a row of hoods or a fan. The Bluetooth transmission module 122 is disposed in the exhaust air. In device 121.

The flow rate detecting and controlling device 13 is connectable to a nozzle opening of the gas container and is connected to the ignition device switch 11 and the Bluetooth wireless exhaust device 12. The flow detection and control device 13 is configured to detect the flammable gas flow rate of the nozzle port, and can determine that the ignition device switch 11 is in an ignition state or a flameout state, wherein when the ignition device switch 11 is in an ignition state or a flameout state, An ignition signal or a flameout signal may be separately generated to the flow rate detecting and controlling device 13 for determining that the ignition device switch 11 is in an ignition state or a flameout state when the flow rate detecting and controlling device 13 receives the ignition signal or the flameout signal.

The flow rate detecting and controlling device 13 and the ignition device switch 11 and the Bluetooth wireless air exhaust device 12 are connected by Bluetooth wireless, for example, respectively, having a Bluetooth transmission module to connect through the Bluetooth technology. In this way, the flow detecting and controlling device 13, the ignition device switch 11 and the Bluetooth wireless exhaust device 12 can be disposed in the same place without being limited, and can be respectively set in different places or rooms to achieve the Bluetooth wireless control function, and then In addition, the installation can also be installed without any need to consider the interior decoration to achieve the convenience of installation.

When the flow rate detecting and controlling device 13 determines that the ignition device switch 11 is in an ignition state, please refer to FIG. 2, and adjust the exhausting effect of the Bluetooth wireless air exhaust device 12 according to the flammable gas flow rate of the nozzle port to make the flammable The gas flow rate is proportional to the exhaust effect of the exhaust device 121 of the Bluetooth wireless exhaust unit 12. For example, the exhaust device 121 may be a fan, and the flow detecting and controlling device 13 accelerates or decelerates according to an increase or decrease in the flow rate of the combustible gas to correspondingly control the rotational speed of the exhaust device 121. In addition, when the flow rate detecting and controlling device 13 determines that the ignition device switch 11 is changed from the ignition state to the flameout state, the Bluetooth wireless air exhaust device 12 may be automatically turned off, or may be turned off after a delay (for example, several seconds). Bluetooth wireless exhaust device 12.

In this case, it is assumed that the user uses the gas stove to cook the vegetables, and the larger the flammable gas flow rate at the nozzle opening is, the stronger the heat is, and the more soot is generated during cooking, and the flow detection and control device 13 corresponds to this time. Enhancing the exhausting effect of the Bluetooth wireless air exhaust device 12, the user does not need to manually adjust the exhaust air speed, effectively accelerate the exhaustion of the oil smoke to the outside, and avoid the user inhaling too much soot; conversely, if the cooking is used, the fire is lower. The flow rate of the flammable gas of the nozzle port is less than that of the oil smoke. The flow rate detecting and controlling device 13 correspondingly reduces the air exhausting effect of the Bluetooth wireless air exhaust device 12, and does not need to be exhausted by a large exhaust effect. Low amount of soot to achieve the effect of saving electricity.
