In order to facilitate understanding of the embodiments of the present invention, the structure of the present invention is explained in detail by several specific embodiments.

The utility model provides a range hood, include: a hood cover 11; the oil collector 15 is connected to an oil discharge port on the range hood cover 11 and used for containing waste oil extracted by the range hood; one end of the oil suction pipe 12 extends into the oil collector 15, and the other end of the oil suction pipe is communicated with the input end of the waste oil treatment pump 13; the waste oil treatment pump 13 is detachably fixed on the range hood 11, and an output end of the waste oil treatment pump 13 is communicated with the oil discharge pipe 14 and is used for extracting the waste oil in the oil collector 15 and discharging the extracted waste oil through the oil discharge pipe 14; and the oil discharge pipe 14 extends to the outside of the hood 11 at one end away from the waste oil treatment pump 13.

In this regard, when the oil collector 15 is to be cleaned, it is only necessary to pump the waste oil in the oil collector 15 through the oil suction pipe 12 by the waste oil treatment pump 13 and then discharge the pumped waste oil through the oil discharge pipe 14, and then the oil collector 15 from which the waste oil has been pumped can be removed and the oil collector 15 can be cleaned. In this process, since the waste oil in the oil collector 15 has been previously drawn out, inconvenience due to splashing of the waste oil can be avoided in the process of unloading the oil collector 15.

Fig. 1 is a schematic structural diagram of a range hood according to a first embodiment of the present application. Specifically, as shown in fig. 1, a first embodiment of the application provides a range hood, and it is worth noting that in this embodiment, the structure, shape and model of this range hood are not limited, and only it needs to meet the requirements of this embodiment, so the range hood shown in fig. 1 is only a structure of this embodiment. Such as: the range hood can be: the upper-discharge range hood, the side-discharge range hood or the lower-discharge range hood can be, of course: a Chinese range hood, a European range hood, a side draft range hood, or a multimedia intelligent range hood.

Specifically, this lampblack absorber includes: a range hood 11, an oil collector 15, an oil suction pipe 12, a waste oil treatment pump 13 and an oil discharge pipe 14; wherein, oil catcher 15 connect in oil drain port on the lampblack absorber cover 11, moreover, this oil catcher 15 is used for holding the waste oil of lampblack absorber extraction, in this embodiment, do not make the limit to the structure and the shape of this oil catcher 15, only need it satisfy the requirement of this embodiment can, if: the oil collector 15 is in the shape of a strip and a bowl. In another embodiment, the oil collector 15 is: an oil cup.

Furthermore, one end of the oil suction pipe 12 extends into the oil collector 15, while the other end is communicated with the input end of the waste oil treatment pump 13;

the waste oil treatment pump 13 is detachably fixed on the hood 11, and the output end of the waste oil treatment pump 13 is communicated with the oil discharge pipe 14 for extracting the waste oil in the oil collector 15 and discharging the extracted waste oil through the oil discharge pipe 14; of course, in another embodiment, the waste oil treatment pump 13 is detachably fixed to the outer side of the hood 11, and of course, may be detachably fixed to the inner side of the hood 11, and may be directly fixed to the hood 11.

Therefore, when the oil collector 15 is to be cleaned, it is only necessary to turn on the waste oil treatment pump 13 to pump out the waste oil in the oil collector 15 through the oil suction pipe 12 by the waste oil treatment pump 13 and then discharge the pumped-out waste oil through the oil discharge pipe 14. In this way, the oil collector 15 from which the waste oil has been drawn out is removed, and then the oil collector 15 is cleaned. In this process, since the waste oil in the oil collector 15 has been previously drawn out, inconvenience due to splashing of the waste oil can be avoided in the process of unloading the oil collector 15.

In another embodiment, the oil collector 15 is transparent so that the user can monitor the amount of oil in the oil collector 15.

In another embodiment, the range hood further includes: and a waste oil discharge port. The waste oil discharge port is opened at the lowest end of the hood 11 for fixing the end of the oil discharge pipe 14 away from the waste oil treatment pump 13. Therefore, the waste oil discharge port can be hidden to ensure the aesthetic property of the range hood.

In another embodiment, the range hood further includes: and a fixed interface 111, wherein the fixed interface 111 is fixed to the waste oil discharge port and is communicated with the oil discharge pipe 14. In this embodiment, the fixing interface 111 is used for detachably fixing the waste oil container 113.

Therefore, only need install this waste oil receptacle 113 on this fixed interface 111 earlier, then open this waste oil treatment pump 13 in order to pass through this waste oil treatment pump 13, take out the waste oil in the oil collector 15 through inhaling oil pipe 12, then discharge the waste oil of taking out to this waste oil receptacle 113 through oil discharge pipe 14, after the extraction is accomplished, only need close waste oil treatment pump 13, then lift this waste oil receptacle 113 off, can be fast convenient the completion from this draw and handle the waste oil in oil collector 13.

In another embodiment, the range hood further includes: the valve 112 is controlled. The control valve 112 is connected to the oil drain pipe 14 for controlling the on/off of the oil drain pipe 14. In this regard, the waste oil is secondarily controlled by the control valve 112 in addition to the waste oil treatment pump 13.

In another embodiment, the end of the oil suction pipe 12 of the range hood, which extends into the oil collector 15, is in a trumpet shape. In this way, the path of the waste oil to the oil suction pipe 12 can be enlarged to avoid the waste oil from blocking the oil inlet of the oil suction pipe 12.

In another embodiment, the range hood further includes: a waste oil filter screen 16, wherein the edge of the waste oil filter screen 16 is fixed on the inner wall of the oil collector 15 and is used for filtering the waste oil flowing into the oil collector 15; of course, the end of the oil suction pipe 12 extending into the oil collector 15 is located between the waste oil filter screen 16 and the bottom of the oil collector 15. In this regard, the extracted waste oil may be filtered to avoid clogging of the waste oil during extraction and discharge. Of course, in this embodiment, the mechanism and shape of the waste oil filter screen 16 are not limited, and only the requirements of this embodiment need be satisfied.

In another embodiment, to improve the filtering efficiency of the used oil, the used oil filtering net 16 may be configured as follows: the waste oil filter screen 16 is arranged obliquely, or the waste oil filter screen 16 is arranged in a conical shape. Of course, the tip in the waste oil filter screen 16 is located between the opening of the waste oil filter screen 16 and the bottom of the oil collector 15; or, the waste oil filter screen 16 is arranged in a conical shape, and the opening of the waste oil filter screen 16 is positioned between the tip of the waste oil filter screen 16 and the bottom of the oil collector 15.

In another embodiment, the range hood further includes: and the waste oil cleaning agent input port 17 is arranged on the oil collector 15, and the waste oil cleaning agent input port 17 is communicated with the inner cavity of the oil collector 15 and is used for injecting the waste oil cleaning agent. In this regard, a proper amount of waste oil cleaning agent may be injected into the oil collector 15 through the waste oil cleaning agent inlet 17 to dilute the waste oil in the oil collector 15 to further prevent the waste oil from clogging during the extraction and discharge processes, and of course, the oil collector 15 may be cleaned thereby. Of course, in the present embodiment, the number and the structure of the waste oil cleaning agent input ports 17 are not limited, and only the requirement of the present embodiment is satisfied, and as shown in fig. 1, two waste oil cleaning agent input ports 17 are provided.
