Description

Technical Field

[0001] The utility model belongs to the technical field of range hood installation structures and relates to a universal sensor installation bracket. Background Art

[0002] Photoelectric fume sensors are becoming the standard configuration of smart range hoods due to their high detection accuracy, fast response time, and good sensitivity. Since the photoelectric fume sensor works on the principle of scattering, it is necessary to place the fume sensor in the air duct of the range hood. Most of them place the fume sensor in the volute or the inner wall of the range hood. However, due to the differences in the shapes and sizes of range hoods, the installation dimensions of the volute or the inner wall of range hoods of different brands and models are different. This makes it difficult for the existing universal fume sensor mounting bracket to be compatible with different installation dimensions. It is always necessary to formulate mounting brackets of different specifications for range hoods of different brands and models, which makes the existing universal fume sensor mounting bracket incompatible and installable, and also increases the installation cost of the fume sensor in range hoods of different brands and models.

[0003] Therefore, in view of the above-mentioned defects of the existing universal oil smoke sensor mounting bracket, the utility model discloses a universal sensor mounting bracket. Utility Model Content

[0004] The utility model aims to provide a universal sensor mounting bracket, which is compatible with different installation sizes of volutes or inner walls of range hoods of different brands, models and specifications, and is compatible with the installation of oil fume sensors with a set of mounting structures.

The end of the second mounting bracket away from the first mounting bracket is a connecting end and is provided with a second connecting part, and the end of the second mounting bracket close to the first mounting bracket is a hinged end and is relatively rotatably connected with the first mounting bracket. By relatively rotating the first mounting bracket and the second mounting bracket, the spacing between the first connecting part and the second connecting part changes, and the spacing between the first connecting part and the second connecting part refers to the straight line distance between the first connecting part and the second connecting part. For different sizes of range hood volutes, it is only necessary to adjust the spacing between the first connecting part and the second connecting part to adapt to the corresponding volute installation size, so as to meet the universal compatible installation of the sensor body inside the range hood volutes of different models and sizes.

[0034] The first mounting bracket 2 and the second mounting bracket 3 are made of plastic and alloy materials, which ensure the strength of the first mounting bracket 2 and the second mounting bracket 3 while reducing the weight of the first mounting bracket 2 and the second mounting bracket 3. A mounting surface for mounting the sensor body 1 is provided on the top of the first mounting bracket 2. A first connecting portion 100 is provided on the end of the first mounting bracket 2 located on the mounting surface away from the second mounting bracket 3. The end of the first mounting bracket 2 located on the mounting surface close to the second mounting bracket 3 is a hinged end, and the end of the mounting surface close to the first connecting portion 100 is higher than the end of the mounting surface close to the second mounting bracket 3, so that the mounting surface is in a state of gradually decreasing height and tilting along the direction from the first connecting portion 100 to the second mounting bracket 3, ensuring that the oil stains condensed and deposited on the mounting surface can slide smoothly along the mounting surface toward the connected plate 3, and avoiding a large amount of oil stains from being deposited on the mounting surface of the first mounting bracket 2. The sensor body 1 is detachably mounted in the area between the first connecting portion 100 and the hinged end on the mounting surface, and the detection axis of the sensor body 1 corresponds to the internal air duct of the range hood volute, ensuring that the sensor body 1 can smoothly detect the concentration of oil smoke inside the air duct.
