Description

Technical Field

[0001] This utility model relates to the field of health and wellness technology, and in particular to a household gas monitor. Background Technology

[0002] In the field of health and wellness technology, home gas monitors are crucial devices for ensuring home safety. Their core function is to detect leaks of methane and other gases in the home in real time, preventing accidents. However, existing home gas monitors have significant shortcomings in installation compatibility, making it difficult to meet the installation needs of different households in various scenarios. 1. Most products only support a single installation method. For example, some monitors are only designed for screw fixing, which requires drilling holes and driving screws into the wall, cabinet or other mounting locations. This is not only cumbersome, but may also damage the mounting surface (such as tiles or wooden cabinets), making them particularly unsuitable for tenants or users who do not want to damage their decoration.

[0003] 2. The existing installation structure has poor versatility. The size of the installation space (such as a kitchen corner or near the gas meter) and the material of the installation surface vary greatly among different households. Monitors with a single installation method often have difficulty finding a suitable installation location. They are either left idle because they cannot be fixed, or their detection sensitivity is reduced due to improper installation location (such as being far away from areas where gas leaks may occur), making it impossible to provide timely warnings of risks. This seriously restricts the actual application effect of home gas monitors and reduces users' willingness to use them.

[0004] Therefore, there is an urgent need for a home gas monitor to solve the above problems. Utility Model Content

[0023] Reference Figures 1-5 The manufacturer includes multiple magnetic components (40) and mounting plates (50) with the shipment, along with multiple bolts, allowing users to choose according to their actual needs; see reference. Figure 1This is the first installation method for the gas detector. In this embodiment, the user can install multiple magnetic components 40 into the slots 13 on the housing 10. The installation method can be interference fit or adhesive. When in use, the entire gas detector is magnetically connected to the metal component to achieve magnetic installation, quickly fix the device, and eliminate the need to drill holes to damage the installation surface. The operation is convenient and damage-free.

[0024] Reference Figures 2-5 This is a second installation method for the gas monitor. In this embodiment, the user can install one end of multiple mounting pieces 50 onto the slot 13. Preferably, the back of the housing 10 is provided with multiple bosses 60, the slot 13 is set on the bosses 60, and the side end of the bosses 60 is provided with a limiting notch 61 communicating with the slot 13. The middle section of the mounting piece 50 extends into the limiting notch 61. Furthermore, the bottom of the slot 13 is provided with a threaded hole 62, one end of the mounting piece 50 is provided with a first through hole 63, and a bolt is also included. The bolt passes through the first through hole and is threadedly connected to the threaded hole 62. Furthermore, the other end of the mounting piece 50 is provided with a second through hole 64.

[0025] Specifically, during installation, one end of the mounting piece 50 is inserted into the slot 13, so that the first through hole 63 is opposite to the threaded hole 62, the middle section of the mounting piece 50 extends into the limiting notch 61, and the other end of the mounting piece 50 extends to the outside of the side end of the housing 10. The limiting notch 61 restricts the swing of the mounting piece 50. Then, corresponding holes are made on the mounting position, and bolts are used to pass through the second through hole 64 and lock into the holes to realize the bolt connection and fixation between the gas monitor and the mounting position.

[0026] Reference Figure 1 This is the third installation method for the gas detector. In this embodiment, the user can also apply nail-free adhesive to the slot 13 for adhesive bonding.

[0027] Reference Figures 2-5 As a preferred option, the first through hole 63 is set as a countersunk hole, which can hide the head of the bolt and avoid affecting the installation.

[0028] Reference Figures 2-5 In some embodiments, there are four slots 13 evenly distributed around the back of the housing 10, and correspondingly, there are also four magnetic suction pieces 40 and four mounting pieces 50.

The first quick-connect threaded connector 91 is connected to the air inlet 11, and the second quick-connect threaded connector 92 is connected to the air outlet 12. This enables quick connection of pipes or expansion of corresponding accessories, improving the ease of use.

[0032] In other embodiments, the control board 20 is equipped with a wireless communication module, such as a 4G or 5G communication module, which can feed back the detected data to the user's mobile terminal. In particular, when the detected concentration is greater than a threshold, an alarm signal will be sent to the mobile terminal. At the same time, the control board 20 can also be configured with an audible alarm module and / or a visual alarm module to alert the user in the room that a gas leak has occurred. In a further embodiment, the monitor can also be connected to a smart home system, which can automatically open electric windows to ventilate the room when a gas leak is detected, thus preventing gas from accumulating in the room.

[0033] The advantages of this invention are as follows: the structure allows for the selective assembly of magnetic components or mounting plates through the slots, forming two core installation methods: magnetic installation and screw installation. When the mounting position is made of metal, the magnetic component is inserted into the slot, and the device is quickly fixed by magnetic attraction without drilling or damaging the mounting surface, making the operation convenient and damage-free. When the mounting position is made of non-metallic material, one end of the mounting plate is inserted into the slot, and the other end is fixed to the mounting position with a screw, achieving stable assembly and adapting to installation environments without metal carriers. The two methods can be flexibly switched, covering the installation scenarios of most households and greatly improving the versatility of the device.
