For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] Reference below Figures 1 to 7 The invention describes a chandelier with a fume purification function provided according to an embodiment of the invention.

[0044] like Figures 1 to 5 As shown, the chandelier with oil fume purification function according to the embodiment of the utility model has an unfolded use state and a folded storage state. It can reduce the occupied space after being folded and stored. Moreover, it can also accurately filter and purify the smoke for multiple dining seats on the dining table at the same time, and the smoke purification effect is good.

[0045] The chandelier with oil fume purification function of this embodiment can be applied to a dining table with multiple dining seats, and the dining seats can be hot pot seats, barbecue seats, etc. where smoke can be generated. In order to better describe this embodiment, the chandelier with oil fume purification function is described in the installation state.

[0046] The chandelier with oil fume purification function of this embodiment includes a fixing component, a lamp assembly, an umbrella-type lifting mechanism 600 , a driving mechanism 200 and a range hood 500 .

[0047] The upper end of the fixing assembly is provided with a mounting portion, and the mounting portion is used to be hung on the ceiling. In this embodiment, the fixing assembly includes a ceiling cup 100, and the ceiling cup 100 can be installed on the ceiling. Further, the lower surface of the ceiling cup 100 can be provided with a decorative piece, and the decorative piece can be a crystal decorative piece.

[0048] The umbrella lifting mechanism 600 is disposed below the fixed component, and the umbrella lifting mechanism 600 is fixedly connected to the lower end of the fixed component, so that the fixed component provides a pulling force for the umbrella lifting mechanism 600, so that the umbrella lifting mechanism 600 can be stably suspended below the ceiling. The umbrella lifting mechanism 600 has a central axis extending in the up-down direction and a plurality of connecting parts, wherein the plurality of connecting parts are arranged in a circle around the central axis of the umbrella lifting mechanism 600. There are a plurality of range hoods 500, and the plurality of range hoods 500 are respectively connected to the plurality of connecting parts, so that the connecting parts of the umbrella lifting mechanism 600 provide an installation position and a support function for the range hood 500.

[0049] It is understandable that the number of the range hoods 500 is consistent with the number of the connecting parts of the umbrella-type lifting mechanism 600, and can be set according to actual needs, and is not specifically limited here. Figure 1 As shown, the number of range hoods 500 is 10. Therefore, the chandelier with oil fume purification function can provide effective smoke suction and purification functions for 10 dining seats respectively. At this time, the 10 dining seats such as hot pot seats are evenly arranged along the circumference of the dining table.

[0050] The umbrella-type lifting mechanism 600 is configured to be able to be unfolded with the central axis extending in the up-down direction as the central axis, so that the multiple connecting parts are separated from each other, so that the range hood 500 on each connecting part can be moved to above the corresponding dining seat to achieve a precise smoke purification function; moreover, the umbrella-type lifting mechanism 600 is also configured to be able to be retracted with the central axis extending in the up-down direction as the central axis, so that the multiple connecting parts are close to each other, so that all the range hoods 500 are in a storage state, thereby reducing the horizontal space occupied by all the range hoods 500.

[0051] The driving mechanism 200 is configured to drive the umbrella-type lifting mechanism 600 to expand or contract. It is understandable that the driving mechanism 200 can provide a driving function for the umbrella-type lifting mechanism 600, so that the umbrella-type lifting mechanism 600 can move to achieve automatic expansion or automatic folding, thereby improving the automation of the chandelier with oil fume purification function.

[0052] The irradiation surface of the lamp assembly can be arranged vertically downward or tilted downward, so that the lamp assembly can provide good lighting. In some examples, the lamp assembly can be connected to the fixed assembly through a hanging rope or a hanging rod, so that the lamp assembly can maintain a stable hanging state and emit light downward, thereby providing a good dining environment. In other examples, the lamp assembly can be fixedly connected to the umbrella lifting mechanism 600 through a support rod, and the umbrella lifting mechanism 600 is fixedly connected to the fixed assembly, so that the lamp assembly is indirectly connected to the fixed assembly.

[0053] In this embodiment, if Figures 1 to 3 As shown, the umbrella lifting mechanism 600 includes a support rod 660 , a first connecting sleeve 610 , a second connecting sleeve 620 , a first connecting rod 630 and a second connecting rod 640 .

[0054] The length of the support rod 660 extends in the up-down direction, and the upper end of the support rod 660 is fixedly connected to the lower end of the fixing assembly. The upper end of the support rod 660 can be fixedly connected to the ceiling cup 100 by welding, threading, etc. The support rod 660 can be coaxially arranged with the ceiling cup 100. The lamp assembly can be fixedly connected to the support rod 660 by a support rod.

[0055] The first connecting sleeve 610 is sleeved on the support rod 660, and the first connecting sleeve 610 is slidably connected with the support rod 660 in the up-down direction, and the first connecting sleeve 610 is coaxially arranged with the support rod 660. Specifically, the first connecting sleeve 610 is provided with a through hole, and the inner circumference of the through hole contacts the outer circumference of the support rod 660. In this embodiment, the support rod 660 is a round rod.

[0056] The output end of the driving mechanism 200 is fixedly connected to the first connecting sleeve 610. When the driving mechanism 200 is running, the output end of the driving mechanism 200 can drive the first connecting sleeve 610 to move up and down relative to the support rod 660. The driving mechanism 200 can be fixed on the support rod 660 or on a fixed component. It can be understood that the driving mechanism 200 is used to drive the first connecting sleeve 610 to move linearly in the up and down direction. The driving mechanism 200 can be a linear driving device such as an electric cylinder, a linear module, a hydraulic cylinder, etc.

[0057] The second connecting sleeve 620 is located below the first connecting sleeve 610, and the second connecting sleeve 620 is sleeved on the support rod 660, and the second connecting sleeve 620 is coaxially arranged with the support rod 660. The second connecting sleeve 620 is fixedly connected to the support rod 660. It can be understood that the maximum distance and the minimum distance between the first connecting sleeve 610 and the second connecting sleeve 620 in the up and down directions can be set according to actual conditions. When the driving mechanism 200 is running, the first connecting sleeve 610 moves upward, and after moving into place, the height distance between the first connecting sleeve 610 and the second connecting sleeve 620 reaches the maximum value; when the driving mechanism 200 is running in the reverse direction, the first connecting sleeve 610 moves downward, and after moving into place, the height distance between the first connecting sleeve 610 and the second connecting sleeve 620 reaches the minimum value.

[0058] There are multiple first connecting rods 630, and the multiple first connecting rods 630 are evenly arranged around the circumference of the support rod 660. In this embodiment, the number of the first connecting rods 630 is the same as the number of the range hood 500. The upper end of each first connecting rod 630 is hinged to the first connecting sleeve 610 through a hinge shaft, wherein the axial direction of the hinge shaft is perpendicular to the up and down direction. The lower end of each first connecting rod 630 is set as a connecting part, and the range hood 500 is fixedly connected to the lower end of the first connecting rod 630.

[0059] There are multiple second connecting rods 640, and the multiple second connecting rods 640 are evenly arranged around the circumference of the support rod 660. In this embodiment, the number of the second connecting rods 640 is the same as the number of the first connecting rods 630, and the multiple second connecting rods 640 are respectively arranged in a one-to-one correspondence with the multiple first connecting rods 630. One end of each second connecting rod 640 is hinged to the second connecting sleeve 620 through a hinge shaft, and the other end of the second connecting rod 640 is hinged to the second connecting rod 640 through a hinge shaft, and the axial direction of the hinge shaft is perpendicular to the up and down direction.

[0060] like Figure 2 and Figure 3As shown, when the driving mechanism 200 drives the first connecting sleeve 610 to move upward along the support rod 660, the second connecting sleeve 620 is fixed relative to the support rod 660, and the vertical distance between the first connecting sleeve 610 and the second connecting sleeve 620 increases. The upper end of the first connecting rod 630 moves upward with the first connecting sleeve 610, and the second connecting rod 640 exerts a limiting effect on the first connecting rod 630, causing the first connecting rod 630 to swing downward around the hinged end thereof and the first connecting sleeve 610, so that the first The acute angle formed by the connecting rod 630 and the supporting rod 660 becomes smaller. At the same time, the second connecting rod 640 swings upward around the hinged end with the second connecting sleeve 620, and the range hood 500 moves upward with the first connecting rod 630. Therefore, all the first connecting rods 630 drive the range hood 500 to retract, and all the second connecting rods 640 are also retracted accordingly, so that the chandelier with oil fume purification function is in a folded storage state, reducing the space occupied by the chandelier with oil fume purification function when not in use.

[0061] When the driving mechanism 200 drives the first connecting sleeve 610 to move downward along the support rod 660, the vertical distance between the first connecting sleeve 610 and the second connecting sleeve 620 decreases, and the upper end of the first connecting rod 630 moves downward along with the first connecting sleeve 610, while the first connecting rod 630 is restricted by the second connecting rod 640, so that the first connecting rod 630 swings upward around the hinged end with the first connecting sleeve 610, so that the acute angle between the first connecting rod 630 and the support rod 660 becomes larger, and at the same time, the second connecting rod 640 swings upward around the hinged end with the first connecting sleeve 610. Its hinged end with the second connecting sleeve 620 swings downward, and the range hood 500 moves downward with the first connecting rod 630. Therefore, all the first connecting rods 630 drive the range hood 500 to unfold, and all the second connecting rods 640 also unfold accordingly, so that the chandelier with oil fume purification function is in an unfolded and used state. At this time, each range hood 500 corresponds to each dining seat on the dining table, and the range hood 500 is in a horizontal state. The upper and lower distances between the range hood 500 and the dining table can be set according to actual conditions, and are not specifically limited here.

[0062] Further, such as Figure 2 and Figure 3 As shown, the umbrella lifting mechanism 600 also includes a third connecting rod 650. There are multiple third connecting rods 650, and the number of the third connecting rods 650 is the same as the number of the first connecting rods 630. The multiple third connecting rods 650 correspond to the multiple first connecting rods 630 one by one and are arranged in parallel, and the multiple third connecting rods 650 are evenly arranged around the circumference of the support rod 660. The upper end of each third connecting rod 650 is hinged to the first connecting sleeve 610 through a hinge shaft, and the lower end of each third connecting rod 650 and the lower end of each first connecting rod 630 are hinged to the range hood 500 through a hinge shaft, and the two hinged ends of the first connecting rod 630 and the two hinged ends of the third connecting rod 650 form a parallelogram.

[0063] The hinge axes of the first connecting rod 630, the second connecting rod 640 and the third connecting rod 650 are all perpendicular to the up-down direction. In this embodiment, the third connecting rod 650 is located on the side of the first connecting rod 630 away from the support rod 660, the hinge end of the third connecting rod 650 and the first connecting sleeve 610 is higher than the hinge end of the first connecting rod 630 and the first connecting sleeve 610, and the hinge end of the third connecting rod 650 and the range hood 500 is higher than the hinge end of the first connecting rod 630 and the range hood 500. Moreover, the hinge end of the first connecting rod 630 and the first connecting sleeve 610, the hinge end of the first connecting rod 630 and the range hood 500, the hinge end of the third connecting rod 650 and the range hood 500, and the hinge end of the third connecting rod 650 and the first connecting sleeve 610 are connected in sequence to form a parallelogram.

[0064] According to the parallelogram rule, when the first connecting sleeve 610 moves in the up and down directions, the first connecting rod 630 and the third connecting rod 650 always remain parallel to each other, and the range hood 500 can maintain a horizontal state.

[0065] It can be understood that the first connecting rod 630, the second connecting rod 640 and the third connecting rod 650 can be split into two parallel rods.

[0066] Of course, it is not ruled out that in other embodiments, the first connecting sleeve 610 is fixed to the support rod 660, the second connecting sleeve 620 is slidably connected to the support rod 660 up and down, the output end of the driving mechanism 200 is connected to the second connecting sleeve 620, and can drive the second connecting sleeve 620 to move in the up and down directions. At this time, when the umbrella-type lifting mechanism 600 switches from the unfolded state to the folded state, the position of the range hood 500 becomes relatively lower; when the umbrella-type lifting mechanism 600 switches from the folded state to the unfolded state, the position of the range hood 500 becomes relatively higher.

[0067] In this embodiment, if Figures 1 to 3 As shown, the driving mechanism 200 includes a lead screw 210 , a connecting member 670 and a rotating driving member 220 .

[0068] The length of the screw rod 210 extends in the up and down directions, and the support rod 660 is hollow inside to form a accommodating cavity. The screw rod 210 is arranged in the accommodating cavity of the support rod 660. The upper and lower ends of the screw rod 210 can be fixed on the support rod 660 through bearing seats. The screw rod 210 is coaxially arranged with the support rod 660. The height position of the screw rod 210 remains unchanged relative to the support rod 660, and the screw rod 210 can rotate around its own central axis relative to the support rod 660.

[0069] The connecting piece 670 is threadedly connected to the screw rod 210. Specifically, the connecting piece 670 is provided with a threaded through hole connected to the screw rod 210. The peripheral wall surface of the support rod 660 is provided with at least one guide hole 661. The number of the guide holes 661 can be determined according to actual conditions. The length of the guide hole 661 extends in the up-down direction. The guide hole 661 is communicated with the accommodating cavity. The connecting piece 670 is slidably connected to the guide hole 661 up and down, and the connecting piece 670 is fixedly connected to the first connecting sleeve 610.

[0070] In this embodiment, the connecting member 670 includes a third connecting sleeve and a connecting arm. The third connecting sleeve is threadedly connected to the screw rod 210. One end of the connecting arm is fixedly connected to the outer circumference of the third connecting sleeve. The other end of the connecting arm passes through the guide hole 661 and is fixedly connected to the inner circumference of the first connecting sleeve 610. Moreover, the connecting arm contacts the two side walls of the guide hole 661. The guide hole 661 can guide and stop the connecting arm. Subsequently, during the rotation of the screw rod 210, the connecting member 670 is enabled to drive the first connecting sleeve 610 to move in a straight line along the length direction of the screw rod 210.

[0071] The output end of the rotary drive member 220 is fixedly connected to one end of the screw rod 210. When the rotary drive member 220 is running, the output end of the rotary drive member 220 can drive the screw rod 210 to rotate relative to the support rod 660 around the central axis extending up and down. It can be understood that the rotary drive member 220 can be set at the upper end of the support rod 660 or at the lower end of the support rod 660. The rotary drive member 220 includes a motor and a transmission structure, wherein the transmission structure can be a coupling, a reducer, etc.

[0072] In this embodiment, the upper end of the support rod 660 is fixedly connected to the ceiling cup 100, and the accommodating cavity of the support rod 660 passes through the upper end of the support rod 660. The ceiling cup 100 has a accommodating cavity with an opening facing upward, and the accommodating cavities are connected to each other. The rotating driving member 220 is arranged in the accommodating cavity of the ceiling cup 100 to be protected.

[0073] In this embodiment, if Figure 4 and Figure 5 As shown, the structure of the range hood 500 includes a housing 510, a fan 540 and a filter element.

[0074] The shell 510 is hollow inside to form a wind cavity, the lower surface of the shell 510 is provided with an air inlet 517, the upper surface of the shell 510 is provided with an air outlet 515, and the air inlet 517 and the air outlet 515 are both connected to the wind cavity. The fan 540 is arranged in the wind cavity of the shell 510. When the fan 540 is working, the smoke can flow into the wind cavity through the air inlet 517 and then flow out from the air outlet 515. The filter element is arranged at the air inlet 517 of the shell 510, and the filter element can filter and purify the smoke. The filter element can be a filter cotton or a high-efficiency filter.

[0075] In this embodiment, the fan 540 is a centrifugal fan. The housing 510 can be made of plastic. A plurality of air inlets 517 and air outlets 515 are provided and distributed in a grid.

[0076] Further, such as Figure 4 and Figure 5 As shown, the range hood 500 further includes a light bar 530. The light bar 530 is disposed on the lower surface of the housing 510, the light bar 530 is fixed relative to the housing 510, the light bar 530 is disposed around the outer periphery of the air inlet 517, and the light bar 530 emits light downward. The light bar 530 may be in a circular ring shape or in an arc shape. In this embodiment, the light bar 530 is an LED silicone light strip. It is understandable that such a design enables the range hood 500 to have both smoke purification and lighting functions.
