Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas, specifically to a household gas alarm. Background Technology
[0002] Common gas safety hazards are often eliminated through user reports and maintenance personnel using instruments to detect them, which may not be able to detect hazards in a timely manner.
[0003] In some residential communities, gas alarms are installed near gas facilities to meet safety requirements. Typically, each household has an inlet gas pipeline in the kitchen, where a flow meter and valve are installed. The valve connects to a flexible hose, which in turn connects to the stove or water heater. Household gas alarms are generally installed near the inlet gas pipeline to monitor gas safety. During renovations, gas pipelines may be enclosed within kitchen cabinets. Therefore, the installation location of the household gas alarm needs to be determined based on the renovation situation. The common method for fixing gas alarms is by drilling and screwing. However, if installed in a suitable location, the gas alarm may not be able to accurately detect gas leaks because it is too far from the detection point. Utility Model Content
[0004] The purpose of this utility model is to solve the above problems and provide a household gas alarm. By using a detachable magnetic mounting plate, the household gas alarm can be easily installed at the inlet of the gas pipeline or the gas inlet of the gas stove. The arc-shaped or square mounting plate can fit the bottom of the pipeline or stove better, allowing the gas alarm to be installed closer to the leak point, making the collection results more accurate.
[0005] To achieve the above objectives, the present invention adopts the following technical solution.
[0006] A household gas alarm includes a housing, a slot on one side of the housing, the slot being detachably connected to a mounting plate, a magnetic plate on the side of the mounting plate away from the housing, a metal cover on the side of the housing away from the mounting plate, through holes evenly distributed on the metal cover, and a flow guide plate on the housing, the flow guide plate having flow guide holes and flow guide grooves, the flow guide holes being inclined relative to the flow guide plate.
[0007] Furthermore, the shell is disc-shaped.
[0008] Furthermore, the mounting plate is arc-shaped.
[0009] Furthermore, the mounting plate is square.
[0010] Furthermore, the metal outer cover is detachably mounted on the housing.
[0011] Furthermore, the deflector plate is detachably mounted on the housing.
[0012] Furthermore, the guide grooves are arranged radially on the guide plate.
[0013] Furthermore, the guide holes are distributed in a gradually varying pattern on the guide plate.
[0014] Furthermore, the housing is equipped with a sensor, a power module, a transmission processing module, and an alarm module; the power module is connected to the sensor, the transmission processing module, and the alarm module, the sensor is connected to the transmission processing module, and the transmission processing module is connected to the alarm module.
[0015] Furthermore, the flow guide hole is positioned towards the sensor.
[0016] The positive effects of this utility model of a household gas alarm are:
[0017] This invention utilizes a detachable magnetic mounting plate, allowing for easy installation of a household gas alarm at the gas pipeline inlet or the gas inlet of a gas stove. The arc-shaped or square mounting plate fits the pipe or the bottom of the stove more closely, enabling the gas alarm to be installed closer to the leak point for more accurate data collection. Furthermore, due to the special environment of the kitchen, adding a fan to increase airflow or using heating to increase airflow is not suitable. The guide holes and guide grooves on the casing, through their physical structure, improve gas collection efficiency, thereby enhancing the accuracy of the gas alarm. Attached Figure Description

[0022] The following describes a specific embodiment of a household gas alarm according to the present invention, in conjunction with the accompanying drawings. However, it should be noted that the specific embodiments described are not intended to limit the specific implementation of the present invention. Any similar structures and similar variations of the present invention should be included within the protection scope of the present invention. The following description of the embodiments is based on the accompanying drawings and is used to illustrate specific embodiments in which the present invention 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 the present invention, and not for limiting the present invention.
[0023] See Figure 1 A household gas alarm includes a housing 1. A slot 2 is provided on one side of the housing 1, and the slot 2 is detachably connected to a mounting plate 3. A magnetic suction plate 4 is provided on the side of the mounting plate 3 away from the housing 1. A metal outer cover 5 is provided on the side of the housing 1 away from the mounting plate 3. Through holes are evenly distributed on the metal outer cover 5. A flow guide plate 6 is also provided on the housing 1. The flow guide plate 6 has flow guide holes 7 and flow guide grooves 8. The direction of the flow guide holes 7 is inclined relative to the flow guide plate 6. In this embodiment, the direction of the flow guide holes 7 is set at 35 degrees relative to the flow guide plate 6, and the extension line of the direction of the flow guide holes 7 intersects the sensor.
[0024] The housing 1 is disc-shaped. Inside the housing 1 are a sensor (for collecting the concentration of gas in the air), a power module (to provide power to the gas alarm), a transmission processing module (responsible for receiving signals from the sensor and transmitting them to a host computer; triggering an alarm module when the gas concentration exceeds a set threshold), and an alarm module (including an audible and visual alarm module). The power module is connected to the sensor, the transmission processing module, and the alarm module; the sensor is connected to the transmission processing module; and the transmission processing module is connected to the alarm module. The sensor is located in the center of the housing 1.
[0025] In one embodiment, the mounting plate 3 is arc-shaped, with its curvature perfectly matching the curvature of the gas pipe, allowing it to be installed in curved areas. In another embodiment, the mounting plate 3 is square, allowing it to be installed on flat areas such as the bottom of the stove. The metal outer cover 5 is detachably mounted on the housing 1, and the guide plate 6 is detachably mounted on the housing 1. The guide grooves 8 are radially arranged on the guide plate 6, with guide holes 7 at both ends of the guide grooves 8. The guide holes 7 are distributed in a gradually changing pattern on the guide plate 6, with the guide holes 7 respectively located on the outer and inner rings of the guide plate 6.
[0026] This utility model, by employing a detachable magnetic mounting plate 3, allows for easy installation of a household gas alarm at the inlet of the gas pipeline or the gas inlet of the gas stove. The arc-shaped or square mounting plate 3 can fit more closely to the bottom of the pipeline or stove, allowing the gas alarm to be installed closer to the leak point, resulting in more accurate data collection. At the same time, due to the special environment of the kitchen, it is not suitable to add a fan to increase the airflow rate or to increase the airflow rate through heating. However, the guide holes 7 and guide grooves 8 on the housing 1, through physical structure, can improve the gas collection efficiency, thereby improving the accuracy of the gas alarm.
