So set up, when improving the intensity of collection petticoat pipe 1, simplify the installation.

Example two

As shown in fig. 2 and fig. 5, the difference between the present embodiment and the above-mentioned embodiment is that in the present embodiment, an opening is formed at the center of the connecting piece 212 of the protruding portion 21, and a light assembly is installed at the opening, and the light assembly for a range hood includes a housing 6, a PCB, a reflective cup, a transparent cover 5, and an elastic sheet 7.

Specifically, be provided with the holding tank in the shell 6, PCB board, reflection cup and printing opacity cover 5 superpose in the holding tank in proper order. Through with PCB board, reflection cup and printing opacity cover 5 superpose in the holding tank in proper order, saved occupation space. The PCB board is provided with an LED lamp 8 thereon, and the reflective cup is configured to reflect light emitted from the LED lamp 8. The LED lamp 8 is adopted to replace the existing halogen lamp, the power is low, the heat is not easy to generate, and the reflecting cup is used for reflecting the light emitted by the LED lamp 8, so that the illuminating effect is improved. In this embodiment, for making things convenient for the PCB board to be connected with external power source, the bottom of shell 6 is provided with the through-hole that is linked together with the holding tank, and the bulge (being used for being connected with the power) card of PCB board is gone into in the through-hole, plays fixed spacing effect simultaneously.

As shown in fig. 2 and 5, when mounting, firstly, the elastic sheet 7 is connected to the outer shell 6 by a fastener, then the PCB is placed in the accommodating groove of the outer shell 6, then the reflecting cup and the light-transmitting cover 5 are tightly fitted together and are integrally placed in the outer shell 6, and finally, the whole lighting assembly for the range hood is clamped into the range hood by the elastic sheet 7.

To facilitate the mounting of the light transmissive cover 5 to the housing 6, the light transmissive cover 5 is optionally snap-fitted to the housing 6. To achieve the snap-fit of the cover 5 to the housing 6.

The light component for lampblack absorber that this embodiment provided, when the installation, at first with the fastener with shell fragment 7 connect on shell 6, put into the holding tank of shell 6 with the PCB board again, then with 5 tight-fits together of reflection cup and printing opacity cover, as a whole pack into in the shell 6, go into whole lampblack absorber through shell fragment 7 card with light component for lampblack absorber on can at last.

The light component for the range hood that this embodiment provided, simple structure, the size is little, and occupation space is little, and simple to operate is swift, and the installation effectiveness is high, and the illuminating effect is good, and power is little, is difficult for generating heat, and the installation is firm, is difficult for dropping in long-term use.

In this embodiment, light component installs in the bulge 21 department of decorating cover 2, not installs on collection petticoat pipe 1 to vacate more usage space for collection petticoat pipe 1, in addition, light component installs another benefit in bulge 21 department and lies in, when light component damages, can directly dismantle to decorate cover 2 and get off to maintain, and cost of maintenance is lower, convenient and fast.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and although the present invention has been disclosed with reference to the above preferred embodiment, but not to limit the present invention, any person skilled in the art can make modifications or changes to equivalent embodiments using the above-mentioned teachings without departing from the scope of the present invention, and the embodiments in the above embodiments can be further combined or replaced, but any simple modification, equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention are also within the scope of the present invention.
