Description

Technical Field

[0001] This utility model relates to the field of gas safety, specifically to a clean-free household gas alarm. Background Technology

[0002] With the increasing prevalence of natural gas connections in homes, the demand for household gas alarms is growing in residential areas, especially densely populated ones. Gas alarms are typically installed near the gas usage area and detect gas leaks by alerting residents with sound, light, and a buzzer.

[0003] During the use of household gas alarms, heavy kitchen fumes can cause grease to accumulate and clog the sensor's air inlet, preventing proper monitoring. Cleaning the alarm's casing is essential for its normal operation; however, cleaning household gas alarms also poses safety risks. Non-professionals are at risk of electric shock, and cleaning agents can corrode or damage the alarm. This invention aims to solve the problem of reducing or eliminating the need for cleaning while ensuring the performance and lifespan of household gas alarms. Utility Model Content

[0004] The purpose of this invention is to solve the above problems and provide a cleaning-free household gas alarm. By setting the air intake grille in an upward direction and using multiple oil guide grooves, the problem of oil clogging the air intake grille can be reduced, effectively ensuring the normal operation of the household gas alarm.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] A self-cleaning household gas alarm includes a main body in the shape of a teardrop. An air intake grille is provided at one end of the main body. A buzzer, a status indicator light, and an operation button are provided near the air intake grille. An oil collection tank is provided away from the air intake grille. Oil-absorbing cotton is provided in the oil collection tank. A power cord and a relay connection wire are also provided on the side near the oil collection tank. An oil guide groove is provided on the main body.

[0007] Furthermore, the air intake grille is a porous structure arranged in an array.

[0008] Furthermore, the operation buttons are self-test and mute buttons.

[0009] Furthermore, the oil collection trough is annular.

[0010] Furthermore, the main body is provided with multiple oil guide grooves.

[0011] Furthermore, the oil guide groove is opened from the middle of one end of the body and extends to the oil collection groove.

[0012] Furthermore, the oil guide grooves are distributed in a divergent pattern.

[0013] The advantages of this new type of cleaning-free household gas alarm are:

[0014] Traditional household gas alarms have their air intake grille located at the bottom. In addition to the oil stains adhering to the surface, oil stains can also slide down from the upper part and clog the air intake grille. Now, by setting the air intake grille upwards, this sliding oil stains can be reduced. At the same time, with multiple oil guide grooves, the situation of oil stains clogging the air intake grille can also be reduced, effectively ensuring the normal operation of the cleaning-free household gas alarm.

[0018] The following describes specific embodiments of the self-cleaning household gas alarm of this utility model with reference to the accompanying drawings. However, it should be noted that the specific embodiments described are not intended to limit the specific implementation of this utility model. All similar structures and similar variations of this utility model should be included within the protection scope of this utility model. The following description of the embodiments is based on the accompanying drawings and is used to illustrate specific embodiments in which this utility model can be implemented. Directional terms mentioned in the embodiments, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings. Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model.

[0019] See Figure 1 A self-cleaning household gas alarm includes a body 1, which is teardrop-shaped. An air intake grille 2 is provided at one end of the body 1. A buzzer 3, a status indicator light 4, and an operation button 5 are provided near the air intake grille 2. An oil collection tank 6 is provided away from the air intake grille 2. Oil-absorbing cotton is provided in the oil collection tank 6. A power cord 7 and a relay connection wire 8 are also provided on the side near the oil collection tank 6. An oil guide groove is provided on the body 1.

[0020] The air intake grille 2 is a multi-porous structure with an array of holes, each with a diameter of 2-3 mm. The spacing between the holes is greater than the diameter, and the holes are angled downwards. This design prevents oil and grease from adhering without hindering the entry of fuel gas. Because of the angled openings, fuel gas can also enter through natural convection.

[0021] Power cord 7 is used to connect to a power source to provide power to the gas alarm, and relay connection wire 8 is used to actuate the gas valve. When a gas leak is detected, the relay can automatically cut off the gas supply. In another embodiment, the household gas detector is also equipped with a Bluetooth module. By working with a mobile app, while maintaining a Bluetooth connection, it can transmit data via Bluetooth and display a pop-up alert on the phone screen, providing an extra layer of safety when the sound and light module is insufficient for alerting.

[0022] The operation button 5 is a self-test and mute button. The self-test button is used to check whether the sound and light alarm and relay control functions of the gas alarm are normal. The mute button is used to silence the sound and light alarm.

[0023] The oil collecting groove 6 is annular and is located on the surface of the body 1, but does not penetrate into the interior. The body 1 is provided with multiple oil guiding grooves, which are opened from the middle of one end of the body 1 and extend to the oil collecting groove 6, and the oil guiding grooves are distributed in a radiating pattern.

[0024] During installation, the self-cleaning type household gas alarm should be placed in the same room as the gas-using appliance (gas stove or other). Minimize obstructions between the alarm and the appliance. Install the alarm approximately one meter below the ceiling and about one and a half meters from the gas source. After securing it with adhesive and screws, power it on for preheating. During the audible and visual alarm, the indicator light will flash yellow, and buzzer 3 will run for a few seconds. After preheating, the indicator light will remain solid green, indicating the alarm is operational. When the concentration of the detected gas in the air reaches the alarm set value, the detector will activate, the indicator light will flash red, and buzzer 3 will sound intermittently. A notification will pop up on your mobile phone. In case of a malfunction, the indicator light will remain solid yellow, and buzzer 3 will sound intermittently.

[0025] Traditional gas alarms have their air intake grille 2 located at the bottom. Besides surface grease, grease can also slide down from the upper part and clog the grille 2. By repositioning the air intake grille 2 upwards, this upward-sliding grease is reduced. Furthermore, the addition of multiple oil guide channels further minimizes clogging, effectively ensuring the normal operation of the self-cleaning household gas alarm. Under normal use, the detector has a maximum lifespan of 5 years. Through structural improvements, the detector no longer requires cleaning; only the absorbent cotton needs replacement, maximizing its lifespan.
