[0029] Embodiment 1 The oil fume treatment device provided by the present application comprises a smoke collecting structure located indoors, an air pipe 540 penetrating through a wall or a glass, and a fan system located outdoors.

[0030] As shown in Figures 1-4 , the air outlet of the smoke collecting structure is connected to the non-return valve 310 and then connected to the outdoor fan assembly through the air pipe 540. In other implementable schemes, the non-return valve 310 can not be provided, or a non-return valve can be provided at the smoke outlet of the outdoor fan system. Since no fan assembly is provided in the smoke collecting structure, compared with the smoke collecting structure of the conventional oil fume treatment device, the smoke collecting structure in the present embodiment has a smaller volume.

[0031] As shown in Figure 2 , the smoke collecting structure has a communicating air inlet 3211 and an air outlet.

[0032] The smoke collecting structure comprises a smoke collecting cover 550, a deflection air duct and an oil cup 340.

[0033] The smoke hood 550 comprises a front plate 321, a top plate 322 and a back plate 323, wherein the front plate 321 is arranged to be inclined relative to the horizontal plane, the front is higher than the back, and an air inlet 3211 is arranged on the front plate 321.

[0034] As shown in Figure 2 and Figure 9 , a head cover 324 is formed at the upper edge of the front plate 321, and elements such as a lamp or a key mechanism 380 can be installed inside the head cover 324. Of course, the lamp can be installed at other positions of the smoke hood, for example, on the inclined surface of the front plate 321.

[0035] The front edge of the top plate 322 is connected with the head cover 324, the rear edge of the top plate 322 is connected with the upper edge of the back plate 323, and the lower edge of the back plate 323 is connected with the lower edge of the front plate 321.

[0036] As shown in Figure 4 , specifically, the lower edge of the back plate 323 has a first folded edge 3231 folded forward, the first folded edge 3231 is provided with an oil leakage hole 32311, and an oil cup 340 is connected below the first folded edge 3231. Specifically, the oil cup 340 can be connected with the first folded edge 3231, and the oil stains leaked from the oil leakage hole 32311 can enter the oil cup 340. The oil cup 340 can be connected at the bottom of the smoke hood and exposed outside the smoke hood; the oil cup 340 can also be arranged in a hidden manner inside the smoke hood.

[0037] As shown in Figure 2 , the top plate 322 is provided with an assembly opening, and the assembly opening is arranged on the top plate 322. Specifically, in the embodiment, the number of top plates 322 is two, and the two top plates 322 are arranged left and right (only one side of the top plate 322 is drawn in Figure 2 ), and the interval forms the above-mentioned assembly opening. The lower end opening of the turning air duct is connected with the assembly opening. The rear end port of the turning air duct forms an air outlet and is connected with a check valve 310.

[0038] As shown in Figure 2 , a first oil guide strip 351 is arranged on the inner side wall of the front plate 321, and the first oil guide strip 351 extends in the left-right direction. In the plane of the front plate 321, the first oil guide strip 351 is located above the air inlet 3211, and the length of the first oil guide strip 351 in the left-right direction is greater than or equal to the length of the air inlet 3211 in the left-right direction, so as to shield the oil stains sliding downward. The oil stains flowing downward from above the first oil guide strip 351 will be shielded by the first oil guide strip 351, avoiding entering the air inlet 3211.

[0039] Furthermore, to improve oil drainage efficiency and prevent oil from crossing the first oil guide strip 351 and entering the air inlet 3211, the side of the first oil guide strip 351 facing away from the air inlet 3211 has a protruding structure. The protruding structure protrudes towards the side away from the air inlet 3211, and is higher in the middle and lower on both sides. The first oil guide strip 351 is roughly inverted "V" or "arch" shaped, with a higher middle and lower sides, which can play a role in guiding oil. Oil falling on the protruding structure from above is guided to flow to its left and right sides.

[0040] Furthermore, the first oil guide strip 351 is provided with a second oil guide strip 352 extending downward at both ends. The oil flowing to both ends of the first oil guide strip 351 flows downward along the second oil guide strip 352. The lowest point of the second oil guide strip 352 is lower than the position of the air inlet 3211. The oil flowing down along the second oil guide strip 352 will flow into the oil cup 340.

[0041] like Figure 2 As shown, the inner wall of the upper cover plate 311 of the steering duct is inclined. The front edge of the upper cover plate 311 is connected to the front plate 321, and the front edge of the upper cover plate 311 is lower than the rear edge of the upper cover plate 311. The inclined surface can be flat or curved. In this embodiment, the upper cover plate 311 is set to a curved structure, which can guide the flue gas from bottom to top to flow to the rear, improving the smoke guiding effect. The oil stains adhering to the upper cover plate 311 will flow forward along the inclined surface, and when they flow to the lowest position of the inclined surface, the oil stains will drip. The downward projection of the oil stain dripping position of the upper cover plate 311 is located on the front plate 321 and above the first oil guide strip 351, that is, it can be blocked by the first oil guide strip 351.

[0042] When the fume treatment device is working, the fumes are drawn into the fume collection hood 550 through the air inlet 3211, then flow upwards into the deflecting duct, and finally are discharged from the room to the outside. When the fumes pass through the deflecting duct, they come into contact with its upper cover plate 311, and some oil stains adhere to the inner wall of the upper cover plate 311. The inner wall of the upper cover plate 311 is designed to be inclined, which allows the oil stains to flow upwards to the bottom of the upper cover plate 311 under the action of gravity, that is, towards the front edge of the upper cover plate 311, and finally fall onto the front plate 321. The inclined front plate 321 guides the oil stains downwards.

[0043] A first oil guide strip 351 is installed above the air inlet 3211 to prevent oil from falling. The oil can only flow to the left and right sides of the first oil guide strip 351 and pass through the left and right sides of the air inlet 3211 without passing through the air inlet 3211, thus preventing the oil flowing down from the turning air duct from dripping from the air inlet 3211.

[0044] like Figure 2As shown, the turning air duct further comprises two side plates 312 and a back plate 313 located at the left and right sides of the upper cover plate 311, and the upper cover plate 311, the two side plates 312 and the back plate 313 form a cavity structure with an open lower end, and the back plate 313 is provided with an air outlet for connecting with the check valve 310.

[0045] As shown in the drawings, Figure 5 the lower edge of the side plate 312 is inclined, with the front end being higher and the rear end being lower, so that the oil stains adhered to the lower edge of the side plate 312 will flow backward under the action of gravity and finally flow down from the lowest position (the rear end of the lower edge), and the oil stain dripping position of the lower edge is projected downward on the front plate 321 and located below the air inlet 3211. The oil stains flowing down from the side plate 312 gather at the lower edge thereof, and because the lower edge of the side plate 312 is inclined with the front end being higher and the rear end being lower, the oil stains will flow backward and fall on the front plate 321 at the lowest position, and then flow from the front plate 321 to the oil cup 340. In this embodiment, the oil stain dripping position of the lower edge is projected downward on the first folding edge 3231.

[0046] As shown in the drawings, Figure 2 and Figure 4 In order to increase the structural stability of the back plate 323, the front edge of the first folding edge 3231 is provided with an upwardly folded flange 3232, and the flange 3232 is connected with the lower edge of the front plate 321, and in order to realize normal oil guiding, the flange 3232 is provided with a gap 3233, through which the oil stains on the front plate 321 flow to the first folding edge 3231, and then flow to the oil cup 340 through the oil leakage hole 32311. The number and position of the gap 3233 can correspond to the number and position of the oil leakage hole 32311, so that the oil stains flowing out of the gap 3233 can quickly enter the oil leakage hole 32311 and finally fall into the oil cup.

[0047] As shown in the drawings, Figure 3 The upper edge of the front plate 321 has a second folding edge 3241, which is horizontally arranged, and the front edge of the upper cover plate 311 has a third folding edge 3111, which is also horizontally arranged, and the second folding edge 3241 is connected with the third folding edge 3111 in a top-to-bottom manner. In this embodiment, the second folding edge 3241 is arranged in a horizontal direction and connected with the upper edge of the head cover 324, and the second folding edge 3241 has a first through hole, and correspondingly, the third folding edge 3111 is also arranged in a horizontal direction and provided with a second through hole corresponding to the first through hole, and the first through hole and the second through hole are aligned in a top-to-bottom manner, and a locking member such as a screw and a nut can be used to lock the second folding edge 3241 and the third folding edge 3111 after passing through the first through hole and the second through hole. Of course, other ways can also be used to connect the second folding edge 3241 and the third folding edge 3111, such as clamping or welding.

[0048] Further, a fourth fold 3112 folded vertically downward can be arranged at the rear edge of the third fold 3111, and the lowest point of the fourth fold 3112 is the oil dropping point of the upper cover plate 311. The oil flowing down from the upper cover plate 311 falls on the third fold 3111 and then flows to the fourth fold 3112.

[0049] The oil fume flows out of the oil fume collecting structure and enters the fan system.

[0050] As shown in Figures 11-14 , the fan system includes a fan device 510, and the fan device 510 includes an oil fume inlet 111, an oil fume outlet 112, and a fan assembly located between the oil fume inlet 111 and the oil fume outlet 112, and the fan assembly is used to form an air flow from the oil fume inlet 111 to the oil fume outlet 112.

[0051] The fan device 510 includes a first shell 110 and a movable baffle 120.

[0052] As shown in Figure 13 , the fan assembly is arranged in the first shell 110, and the fan assembly includes a motor and an impeller 130 and the like.

[0053] The shape of the first shell 110 is not limited, and in the embodiment, the first shell 110 is roughly cuboid. The left side wall of the first shell 110 is provided with the oil fume inlet 111. The oil fume inlet 111 is connected with the oil fume collecting device in the room through a flexible air pipe 540, and the negative pressure generated by the fan device 510 is transmitted to the oil fume collecting device through the air pipe 540 to absorb the oil fume generated during cooking in the room.

[0054] As shown in Figures 11-13 , an open mouth can be arranged on the right side wall of the first shell 110, and in the embodiment, the first shell 110 does not have a right side wall, and the right side of the first shell 110 is completely arranged as an open mouth.

[0055] The movable baffle 120 is connected to the inside of the first shell 110, and the movable baffle 120 is movably connected with the first shell 110. The movable baffle 120 can rotate or slide relative to the first shell 110 to change the area of the open mouth blocked. In the closed state, as shown in Figure 13 , the movable baffle 120 blocks part of the open mouth, and the part of the open mouth not blocked forms the oil fume outlet 112. In the open state, the movable baffle 120 is turned to the right side from Figure 13 , and the area of the open mouth not blocked by the movable baffle 120 is larger than the area of the oil fume outlet 112 in the closed state. In the embodiment, when the movable baffle 120 is completely opened, the open mouth is completely exposed, providing the user with the maximum operating space, and the impeller 130 can be taken out of the open mouth, facilitating the maintenance of the impeller 130.

[0056] When the user needs to maintain and clean the inside of the fan device 510, the movable baffle 120 can be opened, and the area of the opening is larger, which can facilitate the user to extend into the inside of the first shell 110 for maintenance and cleaning. After the maintenance and cleaning are completed, the movable baffle 120 is reset.

[0057] As shown in Figure 12 and Figure 13 , in this embodiment, the movable baffle 120 is rotationally connected with the first shell 110. An installation edge 113 can be provided on the bottom plate of the first shell 110. The installation edge 113 and the movable baffle 120 can be connected by using a hinge 140, or a shaft hole is provided on the installation edge 113, and a rotating shaft rotationally connected with the shaft hole is provided on the movable baffle 120, so as to realize the swinging of the movable baffle 120. In this embodiment, the movable baffle 120 rotates around the hinge 140, and the rotating shaft of the hinge 140 is parallel to the plane of the opening, so that the movable baffle 120 can swing towards the inside or outside of the opening.

[0058] As shown in Figure 13 , in order to reduce resistance and improve smoke exhaust efficiency, when the movable baffle 120 is in a closed state, the movable baffle 120 is inclined, and the edge of the movable baffle 120 rotationally connected is closer to the smoke inlet 111 than the edge of the movable baffle 120 forming the smoke outlet 112, that is, the lower edge of the movable baffle 120 is closer to the left side, and the upper edge of the movable baffle 120 is closer to the right side. When the impeller 130 rotates clockwise, the airflow acting on the inner side wall of the movable baffle 120 can move on the inclined surface of the movable baffle 120 towards the impeller 130, because the inner side wall of the movable baffle 120 and the bottom surface of the first shell 110 form an obtuse angle, the airflow flowing through the obtuse angle position has smaller resistance than the right angle, and more smoke can be guided to move with the impeller 130, and finally exhausted to the smoke outlet 112.

[0059] The stop structure is movably connected on the first shell 110, and is used for stopping the movable baffle 120 after moving to the movement path of the movable baffle 120, so as to maintain the closed state of the movable baffle 120.

[0060] As shown in Figure 14 , the stop structure can be movably connected with the first shell 110, or can be detachably connected.

[0061] The stop structure is located on the swinging path of the movable baffle 120 when working, and can support the movable baffle 120 to maintain the closed state. When the stop structure is removed from the first shell 110, the movable baffle 120 without support is turned outward, so that the area of the opening is larger.

[0062] The stop structure can be connected with the first shell 110 by insertion, clamping or threaded connection, so as to realize detachable connection.

[0063] Specifically, in the embodiment, the first shell 110 is provided with a pin hole, and the stop structure includes a pin rod 150 inserted into the pin hole. After the pin rod 150 is inserted into the pin hole, it is located outside the movable baffle 120, and the inclined movable baffle 120 is lapped on the pin rod 150, so that the pin rod 150 maintains the closed state of the movable baffle 120. After the pin rod 150 is pulled out, the movable baffle 120 can be swung outward to open the opening.

[0064] The first shell 110 is also provided with a limiting structure located on the movement path of the movable baffle 120, which is used to stop and position the movable baffle 120 when it is swung from the open state to the closed state. The closed state is the position where the movable baffle 120 is vertically inclined to block the opening, leaving only a part of the opening unblocked to form the smoke outlet, as shown in Figure 14 .

[0065] During the switching from the open state to the closed state, the movable baffle 120 is flipped to the left side. In order to avoid its excessive flipping (over the closed state position) and bumping the impeller 130, the first shell 110 is provided with a limiting structure. In the embodiment, the limiting structure is a stop edge 115 provided on the inner wall of the first shell 110. The stop edge 115 is located on the movement path of the movable baffle 120, and is used to stop and position the movable baffle 120 when it is swung to the closed state position, preventing it from moving further inward.

[0066] The limiting structure and the stop structure cooperate with each other to maintain the movable baffle 120 in the closed state without swinging inward and outward, thereby improving the stability of the movable baffle 120 during operation.

[0067] As shown in Figure 13 and Figure 14 , in order to reduce the entry of foreign matter (such as rainwater, leaves or plastic bags) into the smoke outlet 112, the first shell 110 is provided with a shielding edge 114 located above the smoke outlet 112.

[0068] The movable baffle 120 is provided with a flow guide flange 121 folded outward of the smoke outlet 112 at the edge of the smoke outlet 112; the flow guide flange 121 and the shielding edge 114 are oppositely arranged, and a flow guide gap is formed between them.

[0069] As shown in Figure 13 and Figure 14As shown, the upper and lower arranged flow guide flange 121 and the shielding edge 114 form a guide gap to guide the smoke to be discharged. Further, the shielding edge 114 is located above the flow guide flange 121, and the shielding edge 114 includes a first edge connected with the first shell 110, and a second edge arranged relative to the first edge and lower than the first edge. The inclined shielding edge 114 can play a role of lateral shielding, and can shield a part of the foreign matters blown laterally, so as to reduce the foreign matters entering the smoke outlet 112.

[0070] As shown, Figure 13 The motor is mounted on the front wall of the first shell 110, and the driving shaft of the motor extends in the front-rear direction and is rotationally connected with the rear wall of the first shell 110 (a bearing is arranged between the two). The impeller 130 is located between the front wall and the rear wall and is connected with the driving shaft. The impeller 130 rotates to form an airflow in the circumferential direction, and guides the oil fume to flow from the smoke inlet 111 to the smoke outlet 112. The extension direction of the driving shaft of the motor is not the same as the directions of the smoke inlet 111 and the smoke outlet 112, i.e., the fixed position of the driving shaft is arranged on the surface other than the surfaces of the smoke inlet 111 and the smoke outlet 112. Therefore, the driving shaft of the motor can be connected with other functional devices requiring torque, and the functional devices are located on the side of the second side wall and do not shield or affect the smoke inlet 111 or the smoke outlet 112. In the embodiment, the driving shaft is transmissionally connected with the movable piece of the heat dissipation mechanism 520 to realize the circulation of the cooling medium, so as to reduce the volume and cost of the system. The cooling medium can be a gas or a liquid.

[0071] As shown, Figure 1 The fan system further includes a solar device 560 and an energy storage device 610 connected with the fan device 510. The solar device 560 is electrically connected with the energy storage device 610, and the energy storage device 610 is used to store the electric energy generated by the solar device 560. The energy storage device 610 is electrically connected with the fan device 510. In an implementable scheme, the electric energy converted by the solar device is only used to drive the fan device 510 to work. In other implementable schemes, the energy storage device 610 is electrically connected with the electrical modules (for example, a smoke sensor, a lighting lamp or a key module) on the smoke collecting structure, so as to use the electric energy stored in the energy storage device 610 to drive the smoke collecting structure to work. In still another implementable scheme, the fan device 510 and the electrical modules on the smoke collecting structure all use the electric energy stored in the energy storage device 610.

[0072] As shown, Figure 1As shown, the fan device 510, the energy storage device 610 and the solar device 560 are connected with each other. The three can be arranged in the up-down direction. Since the battery 470 is heavy, the energy storage device 610 is arranged at the lowermost position, and the integrated structure is more stable. The fan device 510 is arranged above the energy storage device 610, and the solar device 560 is arranged above the fan device 510. The solar device 560 is arranged at the uppermost position, which can reduce the shading and facilitate the absorption of solar energy.

[0073] In other implementable schemes, the solar device 560 can include a solar panel, which is covered outside the shell of the fan device 510 or the energy storage device 610, or is directly prepared into the shell of the fan device 510 or the energy storage device 610. Thus, the solar device 560 is integrated with the fan device 510 or the energy storage device 610, and the product volume is reduced.

[0074] As shown in Figure 13 , Figure 19 and Figure 20 , the solar device 560 on the fan system can convert solar energy into electrical energy, which can be stored in the energy storage device 610. When the fan device 510 works, additional electrical energy is provided, which reduces the electricity consumption of the resident household when the oil fume treatment device works. In the embodiment, the fan device 510 is arranged outdoors and is connected with the indoor smoke hood 550 through the air pipe 540, which can reduce the indoor noise.

[0075] As shown in Figure 19 , the energy storage device 610 includes a second shell 521 and a battery 470 arranged inside the second shell 521. Similarly, the shape of the second shell 521 is substantially the same as that of the first shell 110. The first shell 110 and the second shell 521 are connected in the up-down direction, and the bottom surface of the first shell 110 and the top surface of the second shell 521 have the same shape and area, which facilitates the arrangement and installation of the integrated structure.

[0076] As shown in Figure 20 , in order to reduce the heat generated by the fan device 510 from being transferred to the energy storage device 610, a heat insulation layer 570 is arranged between the connecting surfaces of the first shell 110 and the second shell 521.

[0077] As shown in Figure 21 and Figure 22 , the energy storage device 610 includes a heat dissipation mechanism 520, which is used for dissipating heat of the battery 470 in the energy storage device 610.

[0078] The heat dissipation mechanism 520 can include a cooling medium circulation flow channel, which flows through a heat dissipation end and a heat absorption end of the heat dissipation mechanism 520, the heat absorption end is connected with the battery 470, when the cooling medium flows through the heat absorption end, the cooling medium absorbs heat generated by the battery 470 and increases in temperature, then the cooling medium with increased temperature flows through the heat dissipation end, radiates heat to the surrounding air, and the temperature of the cooling medium decreases. The heat dissipation mechanism 520 includes a rotatable movable member 420, and the movable member 420 rotates to drive the cooling medium to circulate.

[0079] In addition, in order to improve the heat dissipation efficiency, a semiconductor heat dissipation sheet or a heat dissipation fin can be arranged at the heat dissipation end, so that the cooling medium flowing through the heat dissipation end is reduced to a lower temperature.

[0080] As shown in Figure 20 and Figure 21 In order to reduce the overall volume and production cost, the driving shaft 531 driving the impeller 130 is connected with the movable member 420, so that the driving shaft 531 drives the impeller 130 and the movable member 420 to move synchronously.

[0081] The movable member 420 can drive the cooling medium to move through rotation or linear reciprocating motion. In the embodiment, the movable member 420 includes a rotatable paddle.

[0082] In the fan system, the fan device 510 and the heat dissipation mechanism 520 share one motor, which drives the impeller 130 and the movable member 420 to rotate together. The rotating impeller 130 forms a negative pressure to absorb oil fume generated during cooking, and the rotating paddle can drive the cooling medium to circulate and flow, thereby achieving heat dissipation.

[0083] In the embodiment, since the first shell 110 and the second shell 521 are arranged in an up-down position, the driving shaft 531 is connected with the movable member 420 through a transmission structure, the transmission structure transmits the torsion of the driving shaft to the movable member, so that the movable member 420 moves. In the embodiment, the movable member 420 includes a rotatable paddle, and the flow of the cooling medium is realized through rotation.

[0084] The transmission structure includes a driving rotating member connected with the driving shaft 531, a driven rotating member connected with the movable member 420, and a torsion transmission member connected between the driving rotating member and the driven rotating member, so that the driving shaft 531 drives the movable member 420 to rotate.

[0085] Therefore, the driving shaft 531 part located outside the first shell 110 is connected with the driving wheel 533. The shaft center of the movable part 420 is connected with the rotating shaft 536, a part of the rotating shaft 536 penetrates through the second shell 521, and is connected with the driven wheel 535. In order to improve the stability of the rotating shaft 536, a bearing can be arranged on the second shell 521, and the inner ring of the bearing is connected with the rotating shaft 536. The flexible transmission ring 534 is connected with the driving wheel 533 and the driven wheel 535 respectively. After the driving shaft 531 rotates, the impeller 130 and the driving wheel 533 are synchronously driven to rotate, the driving wheel 533 drives the lower driven wheel 535 to rotate through the flexible transmission ring 534, and then drives the movable part 420 to rotate through the rotating shaft 536, so as to realize the circulating flow of the cooling medium. The flexible transmission ring can be a flexible transmission ring or a transmission chain.

[0086] In other implementable schemes, the circumferential side wall of the driving wheel 533 and the driven wheel 535 can be provided with a tooth structure, and the torsion transmission member includes a gear which is engaged between the driving wheel 533 and the driven wheel 535.

[0087] As shown in Figure 19 , the fan system further includes a third shell 537 connected with the first shell 110 and the second shell 521 respectively, and the third shell 537 covers the outside of the driving wheel 533, the flexible transmission ring 534 and the driven wheel 535 to protect them. At the same time, during transportation, the fan device 510 and the energy storage device 610 can be transported in a split structure, and then assembled into an integrated structure, and then the flexible transmission ring 534 and the third shell 537 are connected after assembly.

[0088] As shown in Figure 1 and Figure 23 , the solar device 560 includes a mounting seat 630 and a solar panel 620, and the mounting seat 630 is fixedly connected with the top surface of the first shell 110. The solar panel 620 is connected with the mounting seat 630 through a rotating structure, so that the orientation of the solar panel 620 can be adjusted. It is convenient for the user to adjust the orientation of the solar panel 620 according to the season to obtain the maximum solar energy.

[0089] Specifically, the rotating structure includes a connecting rod 640, one end of the connecting rod 640 is connected with the mounting seat 630, and the other end is connected with the solar panel 620. The connecting rod 640 includes at least two hinged rod bodies to change the pitch angle. The lower end of the connecting rod 640 is rotatably connected with the mounting seat 630, and the rotating direction is horizontal (the axis is vertical) to change the horizontal orientation.

[0090] In other implementable schemes, the driving shaft 531 is directly connected with the movable part 420, that is, the movable part 420 and the impeller 130 are coaxially arranged.

[0091] As shown in Figures 24-29As shown, the heat dissipation part of the heat dissipation mechanism 520 includes: a housing 410, a movable part 420, and a heat dissipation part 430.

[0092] Among them, such as Figure 27 As shown, the internal cavity of the outer casing 410 forms a cooling chamber. The movable member 420 is connected to the outer casing 410, and the blades of the movable member 420 can rotate within the cooling chamber, thereby driving the cooling medium within the cooling chamber to flow from the inlet 411 to the outlet 412.

[0093] In this embodiment, the cooling cavity is composed of a semi-circular region at the bottom and a rectangular region at the top. The center of the blade is approximately located at the junction of the upper and lower parts, and the outer edge of the blade sweeps across the upper and lower regions. The circumferential sidewall of the semi-circular region is an arc-shaped sidewall 413, which matches the outer edge of the blade rotation, thereby reducing the flow resistance of the cooling medium.

[0094] The outer casing 410 is provided with an inlet 411 and an outlet 412, which are respectively located on the front and rear walls of the semi-circular region. Cooling medium, which has exchanged heat with the battery 470 and absorbed heat, enters the cooling chamber through the inlet 411 on one side, and then flows between the two blades of the propeller. As the propeller rotates, it pushes the cooling medium to the outlet 412. A heat sink 430, which can be a semiconductor heat sink, can be attached to the outer side of the sidewall corresponding to the area between the inlet 411 and the outlet 412. After the propeller rotates, it carries the hotter cooling medium from the inlet 411 to the heat dissipation area of ​​the semiconductor heat sink for cooling. The cooled cooling medium then flows out through the outlet 412.

[0095] Of course, among other feasible options, the heat sink 430 can also be finned, which has a large heat dissipation area and high heat dissipation efficiency.

[0096] To reduce gaps and improve heat transfer, a first thermally conductive material is filled between the heat sink 430 and the outer casing 410. The first thermally conductive material can be thermally conductive silicone grease, which accelerates the conduction of heat from the cooling medium in the cooling cavity to the heat sink 430.

[0097] like Figure 24 As shown, the heat dissipation mechanism 520 includes a first bracket 440, which can be welded together with the outer shell 410. The first bracket 440 and the outer shell 410 clamp and fix the heat dissipation component 430. The main body of the first bracket 440 has a frame structure, and the middle position is a first window 441 that avoids the heat dissipation surface of the heat dissipation component 430. The structure of the first window 441 facilitates the heat dissipation of the heat dissipation component 430 itself.

[0098] The inlet 411 and the outlet 412 are within the movement range of the paddle, so that the cooling medium entering the cooling cavity can also be directly pushed by the paddle to move quickly to the position where the heat sink 430 is located.

[0099] As shown in Figure 22 , Figures 28-29 , the heat absorption end includes a heat absorption flow channel 451, the inlet of the heat absorption flow channel 451 is connected with the outlet 412, and the outlet of the heat absorption flow channel 451 is connected with the inlet 411; the heat absorption flow channel 451 is arranged in a plane in a spiral coil shape to form a disc body, and the disc body is attached to one side of the battery.

[0100] As shown in Figure 22 , the disc-shaped heat absorption flow channel 451 is attached to one side wall of the battery, the battery 470 is installed on the battery mounting bracket, the lower cooling medium pipe 481 is connected at both ends with the inlet 411 and the internal flow channel outlet of the heat absorption flow channel 451 respectively, the upper cooling medium pipe 482 is connected at both ends with the outlet 412 and the internal flow channel inlet of the heat absorption flow channel 451 respectively, the second bracket 460 is installed on the battery box shell, and the heat absorption flow channel 451 is installed on the second bracket 460.

[0101] Among them, the battery 470 and the heat absorption flow channel 451 are installed with two wall surfaces closely attached, and a second heat conduction material, such as heat-conducting silicone grease, is added to the contact surface of the battery 470 and the heat absorption flow channel 451, so as to facilitate the heat conduction of the battery 470 to the heat absorption flow channel 451.

[0102] In addition, as shown in Figure 22 and Figure 29 , the second bracket 460 is provided with a second window 461 which avoids the heat dissipation surface of the heat absorption flow channel 451, thereby saving materials and improving heat dissipation efficiency. Furthermore, compared with the conventional design of winding the pipeline around the battery 470, the heat absorption flow channel 451 directly contacts the battery 470, has a larger contact area, and the multi-layer bending design of the heat absorption flow channel 451 prolongs the time of the cooling medium flowing through, improves the heat exchange rate, and makes the heat dissipation effect of the battery 470 better.

[0103] In other implementable schemes, the heat absorption flow channel 451 can also be coiled in a cylindrical structure, i.e., the heat absorption flow channel 451 is arranged in a ring shape on the circumferential outer side of the battery, and heat absorption is realized for each surface of the battery.

[0104] As shown in Figure 20 and Figure 33As shown, the impeller 130 includes a shaft tube 512 and blades arranged in parallel with the shaft tube 512. The blades are multiple in number and arranged around the shaft tube 512. The multiple blades can be connected into an integral structure through a front frame, a middle plate and a rear frame, and the middle plate is connected with the shaft tube 512. The shaft tube 512 is provided with a shaft hole penetratingly arranged in the center, and the driving shaft 531 completely penetrates through the shaft hole. Moreover, the shaft tube 512 is locked with the driving shaft 531 through a locking piece 514, so that the driving shaft 531 and the impeller 130 have the same rotating state.

[0105] In other implementable schemes, the driving shaft 531 can also be welded with the impeller 130.

[0106] As shown in Figure 20 , Figures 30-33 As shown, the end of the shaft tube 512 away from the motor body is provided with multiple clamping claws 515 extending in the axial direction, the multiple clamping claws 515 are arranged at intervals in the circumferential direction, and the middle positions of the multiple clamping claws 515 are for the driving shaft 531 to penetrate through. The circumferential outer wall of the clamping claw 515 is provided with external threads. The locking piece 514 is in the shape of a nut and includes internal threads corresponding to the external threads, the locking piece 514 is threadedly connected with the clamping claw 515, and after the locking piece 514 is screwed, the clamping claw 515 that is clamped tightly is pressed against the driving shaft 531, so as to fixedly connect the shaft tube 512 with the driving shaft 531.

[0107] In order to realize positioning installation and improve the synchronism of rotation, the end of the shaft tube 512 facing the driving piece 530 is provided with a clamping groove 513, and the driving shaft 531 is provided with a clamping pin 532. When assembling the driving piece 530 and the impeller 130, the driving shaft 531 can be first penetrated through the end of the shaft tube 512, and when the clamping groove 513 and the clamping pin 532 are clamped, the driving shaft 531 is moved into position, and then the locking piece 514 is screwed. After the clamping groove 513 and the clamping pin 532 are clamped, a limit is formed in the circumferential direction, and when the clamping pin 532 on the driving shaft 531 rotates, it will abut against the groove wall of the clamping groove 513 and push the shaft tube 512 to move together, thereby improving the synchronism.

From top to bottom, the deflector 360 is inclined backward, the oil stains falling from the third folding edge 3111 flow to the deflector 360, and then the oil stains flow forward along the inclined deflector 360 to the front plate 321. During cooking, the oil fume in the smoke collection cover flows upward, then turns 90° and flows backward from the air outlet, the oil stains attached to the upper cover plate 311 flow forward along the inclined surface under the action of gravity, and then flow onto the third folding edge 3111, and then flow downward along the third folding edge 3111 to the deflector 360, and the oil stains continue to flow backward along the inclined deflector 360 to the front plate 321, and the oil stains flow smoothly through each surface without aggregation.

[0109] Moreover, the deflector 360 can be arranged to close the rear end opening of the head cover 324, to isolate the front plate 321 from the lamp or key assembly 380 inside the head cover 324, and to improve the service life of the devices inside the head cover 324.
