Furthermore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

Referring to fig. 1 to 4, a range hood includes a housing 1 and a sensor assembly 2, and the structure of the housing 1 may adopt any structure in the prior art. In this embodiment, taking the side-draft range hood as an example, the range hood may alternatively adopt any form in the prior art.

The sensor mounting structure includes a mounting plate 11 of a mounting base of the sensor unit 2, and in the present embodiment, the mounting plate 11 is one of left and right side walls of the housing 1. The sensor assembly 2 includes a sensor 21 and a mounting box 22 for mounting the sensor 21 to the mounting plate 11. The sensor 21 is fixed in a mounting box 22, and the mounting box 22 is fixed on the side of the mounting plate 11 facing the inside of the housing 1. The sensor 21 is preferably an air quality sensor such as a formaldehyde detection sensor, a TVOC detection sensor, or a natural gas leak detection sensor. When the quality of the detected ambient air is lower than the preset value, the range hood can be automatically started. Alternatively, the sensor 21 may be a smoke sensor, a temperature sensor, or the like, as desired.

The mounting plate 11 is provided with a through hole at a position corresponding to the mounting box 22 to form a detection port 111, the detection port 111 can be one hole or a plurality of holes arranged at intervals to form a whole (similar to a grid), and the mounting box 22 is provided with an opening 221 at a side facing the detection port 111, so that the sensor 21 can be in fluid communication with an object to be detected, such as ambient gas, and thus the ambient gas entering from the detection port 111 can be detected.

Referring to fig. 2 to 7 again, the mounting box 22 includes a box body 222, the opening 221 is formed in the box body 222, and the sensor 21 is disposed in the box body 222. The mounting box 22 further includes a latch 223 and a mounting post 224 provided on a wall surface of the box body 222 opposite to the opening 221 (i.e., a wall surface away from the mounting plate 11). The sensor 21 includes a probe head 211 and a base plate 212, the probe head 211 is disposed on the base plate 212 integrally, and the probe head 211 is preferably oriented toward the detection port 111. The base plate 212 is correspondingly provided with an insertion hole 213 matched with the plug 223 and a mounting hole 214 matched with the mounting post 224, and the sensor 21 and the mounting box 22 can be fixed by inserting the plug 223 into the insertion hole 213 for a predetermined position and then penetrating the mounting post 224 and the mounting hole 214 through a fastener, such as a screw. The latch 223 and the mounting post 224 may also be provided on the substrate 212 of the sensor 21, in which case the receptacle 213 and the mounting hole 214 are formed on the case 222. The above is only an example of one installation manner of the sensor 21 and the installation box 22, and the sensor 21 and the installation column box 22 may also adopt other installation manners, such as gluing, clamping, etc., as long as the relative positions of the two are fixed.

The sensor assembly 2 further includes a moving plate 23 and a moving mechanism 24 for driving the moving plate 23. The detection port 111 can be opened and closed by the movement of the moving plate 23. In this embodiment, the moving plate 23 is moved up and down to close the detection port 111 when it is lowered or raised. In the present embodiment, in order to collect oil stains (which will be described in detail below), the moving plate 23 may be raised above the mounting box 22, see fig. 8 to 10, so as to enable the sensor 21 to be in an operating state, and may also be lowered to the detection port 111 to close the detection port 111 and simultaneously close the opening 221 of the mounting box 22, so as to enable the sensor 21 to be in a non-operating state. With a sensor module in the form of a non-cartridge, it is also possible to protect the sensor module by closing only the detection port 111. Here, the sensor 21 is in an operating state, which means that the sensor 21 can be turned on at any time in this situation to perform normal detection operation, and although the sensor 21 is usually kept on all the time, it is not required that the sensor 21 is always kept on; the sensor 21 is in a non-operating state, which means that the sensor 21 cannot normally perform a detection operation even if it is turned on in this case, rather than that the sensor 21 remains in a turned-off state.

The moving mechanism 24 is configured to drive the moving plate 23 to ascend and descend, and may be a linear driving module, such as an electric push rod in this embodiment, or may be other linear driving modules in the prior art, such as a combination of a motor and a gear rack, a combination of a motor and a lead screw nut, and the like. When the moving plate 23 descends to close the opening 221, the detection port 111 is closed at the same time, and when the moving plate 23 ascends to open the opening 221, the detection port 111 is opened at the same time. The moving plate 23 is closely attached to the inner side of the mounting plate 11, so that oil stains on the inner side of the mounting plate 11 can be scraped downwards, particularly at the detection port 111 and at the periphery of the detection port, in the process of lifting the moving plate 23, thereby preventing the accumulation of the oil stains from influencing the detection of the sensor 21.

The top of the moving plate 23 can be bent laterally to form a bending portion 231, so that the bending portion 231 can abut against the top of the box 222 when the moving plate 23 is lowered to the position for closing the detection port 111, thereby playing a role of limiting, and avoiding the moving mechanism 24 from being locked due to the fact that the moving plate 23 is lowered beyond the lower limit.

The side of the box 222 close to the mounting plate 11 is further provided with a groove 225, the groove 225 is formed by the surface of the box 222 close to the mounting plate 11 sinking towards the direction far away from the mounting plate 11, the groove 225 penetrates through the top of the box 222, and the opening 221 is formed on the wall surface of the groove 225 far away from the mounting plate 11. Thus, the moving plate 23 may be received within the groove 225 as it is lowered, keeping the surfaces flush, and the groove 225 may also provide a guide for movement of the moving plate 23. When the moving plate 23 moves, it abuts against the mounting plate 11, thereby scraping off the oil stain on the inner side wall surface of the mounting plate 11.

The portion of the box 222 below the groove 225 is tightly attached to the mounting plate 11, a through hole 226 is opened on the bottom surface of the groove 225, the through hole 226 is used as an oil leakage hole, and therefore, the oil scraped by the moving plate 23 can flow down along the through hole 226. The cylinder 232 extends downwards from the bottom of the movable plate 23, and when the movable plate 23 descends to the position where the detection port 111 is closed, the cylinder 232 is inserted into the through hole 226, so that the through hole 226 can be dredged, oil stains are prevented from being condensed in the through hole 226 and blocking the through hole 226, and the cylinder 232 can also be beneficial to guiding the scraped oil stains to flow downwards. The bottom of the shell 1 is provided with an oil cup 3, and oil dirt flowing down from the mounting box 22 can be collected into the oil cup 3.

The inner bottom surface 2221 of the box body 222 may be inclined to a certain degree, and gradually inclined downward from the direction away from the mounting plate 11 to the direction close to the mounting plate 11, so that the through hole 226 is located at the lowest position of the bottom of the box body 222, and oil stains in the box body 222 can smoothly enter the through hole 226, thereby avoiding accumulation in the box body 222.

In addition, the sensor mounting structure can be used in other occasions requiring dust prevention, water prevention and the like.
