[0050] Referring to Figure 1 As shown in the drawings, the embodiment of the present application provides a table-top range hood 1 which can be applied to a dining table to suck away the oil smoke and odor generated during cooking. The table-top range hood 1 comprises a range hood body 11, a support 12 and an oil cup 13, the oil cup 13 is hung on the lower side of the air inlet of the range hood body 11, the range hood body 11 is connected with the support 12, the support 12 is used to assemble the range hood body 11 on the table top, and the oil cup 13 is used to collect the oil stains dripping during the operation of the range hood body 11.

[0051] Referring to Figures 2-4 As shown in the drawings, specifically, the range hood body 11 comprises an outer shell 111, a rectifier module 112, a filter module 113, a connecting module 114, a fan 115 and a rear support module 116, the rectifier module 112, the filter module 113, the connecting module 114, the fan 115 and the rear support module 116 are sequentially arranged inside the outer shell 111.

[0052] More specifically, the outer shell 111 comprises an upper shell 1111 and a lower shell 1112, both the upper shell 1111 and the lower shell 1112 are hollow annular shells, the upper shell 1111 and the lower shell 1112 are connected through the connecting module 114, and the oil cup 13 is hung on the upper shell 1111. The rectifier module 112 and the filter module 113 are arranged in the upper shell 1111, and the filter module 113 is located between the rectifier module 112 and the connecting module 114. The fan 115 and the rear support module 116 are arranged in the lower shell 1112, and the fan 115 is located between the connecting module 114 and the rear support module 116. When the table-top range hood 1 is working, the fan 115 rotates, under the action of the fan 115, the oil smoke is sucked into the filter module 113 from the outside wall of the filter module 113 through the flow guide of the rectifier module 112 for filtration, and then enters the fan 115 from the end of the filter module 113 close to the fan 115, and is discharged to the outside through the fan 115.

[0053] Further, the smoke machine body 11 is provided with a movable assembly 117 and a running switch assembly 118, and the movable assembly 117 and the running switch assembly 118 are arranged on the outer circumferential side of the fan 115. The movable assembly 117 is arranged close to the running switch assembly 118, and the movable assembly 117 can move with the inclination of the smoke machine body 11. When the movable assembly 117 moves to a specified position, the running switch assembly 118 is triggered to obtain the inclination angle of the smoke machine body 11 and start the corresponding running mode.

[0054] Optionally, the running mode corresponding to the inclination angle can be voice prompt, indicator light prompt, adjustment of the rotating speed of the fan 115, or shutdown of the fan 115, and the like, which is not limited in the embodiment of the present application.

[0055] Specifically, the fan 115 is electrically connected with the running switch assembly 118, and the fan 115 is used to adjust the rotating speed according to the inclination angle of the smoke machine body 11 recognized by the running switch assembly 118. In the embodiment of the present application, when the smoke machine body 11 is excessively inclined downward, oil stains are easy to drop outside the oil cup 13, and the oil stains can be prevented from dropping by reducing the rotating speed of the fan 115 or shutting down the fan 115. When the smoke machine body 11 is excessively inclined upward, the smoke suction effect of the smoke machine body 11 is poor, and the smoke suction effect of the smoke machine body 11 can be improved by increasing the rotating speed of the fan 115.

[0056] Please continue to refer to Figure 4 As shown in the figure, it can be understood that the inclination angle θ of the smoke machine body 11 represents the angle of the smoke machine body 11 deviating from the vertical plane. The specified position is the position of the movable assembly 117 corresponding to the inclination of the smoke machine body 11 to a certain degree. For example, the position of the movable assembly 117 corresponding to the inclination angle θ of the smoke machine body 11 in the normal state, and / or the position of the movable assembly 117 corresponding to the inclination angle θ of the smoke machine body 11 in the excessively inclined downward state, and / or the position of the movable assembly 117 corresponding to the inclination angle θ of the smoke machine body 11 in the excessively inclined upward state.

[0057] In the embodiment of the present application, the movable assembly 117 is arranged to move with the inclination of the smoke machine body 11, and the movable assembly 117 can cooperate with the running switch assembly 118. When the movable assembly 117 moves to the specified position, the running switch assembly 118 is triggered to obtain the inclination angle θ of the smoke machine body 11, and then different running modes are adopted according to different inclination angles θ. The problem that the table-top smoke machine on the market cannot detect the inclination angle to adapt to different use scenarios can be solved. The inclination angle θ of the table-top smoke machine 1 can be controlled within a certain range in the embodiment of the present application, so as to prevent the excessively large downward inclination angle θ from causing oil stains to drop outside the oil cup 13, or the excessively large upward inclination angle θ from causing the smoke suction effect to be poor, and greatly improve the use experience of the table-top smoke machine 1.

[0058] Please combineFigures 4-7 As shown, specifically, the movable assembly 117 comprises a conduit 1171 and a movable ball 1172, the movable ball 1172 is a magnet and is placed in the conduit 1171. The operation switch assembly 118 comprises a circuit board 1181 and a magnetic force detection device 1182, the magnetic force detection device 1182 is arranged on the circuit board 1181 and is electrically connected with the circuit board 1181, the fan 115 is electrically connected with the magnetic force detection device 1182, and the fan 115 is used for adjusting the rotating speed according to the inclination angle θ of the smoke machine body 11 identified by the magnetic force detection device 1182. When the inclination angle θ of the smoke machine body 11 changes, the movable ball 1172 moves to the lower end of the conduit 1171 under the action of gravity and triggers the corresponding magnetic force detection device 1182, so that the magnetic force detection device 1182 obtains the inclination angle θ of the smoke machine body 11.

[0059] Specifically, the movable ball 1172 is a permanent magnet.

[0060] Specifically, the circuit board 1181 is a PCB board.

[0061] Further, the desktop smoke machine 1 further comprises a prompt device (not shown), the prompt device is electrically connected with the magnetic force detection device 1182, and the prompt device is used for prompting according to the inclination angle θ of the smoke machine body 11 identified by the magnetic force detection device 1182. Optionally, the prompt device can be a voice module, and the voice module is used for voice prompting. Alternatively, the prompt module can be an indicator light, and the indicator light is used for prompting by changing the color or the brightness.

[0062] In the embodiment of the application, the inclination angle θ of the smoke machine body 11 can be provided to the user in a visual angle through the setting of the prompt device, so that the user can avoid excessively inclining the smoke machine body 11 when operating the desktop smoke machine 1.

[0063] In the embodiment of the application, the movable ball 1172 moves in the conduit 1171 along with the inclination of the smoke machine body 11 and then triggers the corresponding magnetic force detection device 1182. Since the corresponding magnetic force detection device 1182 can be triggered only when the movable ball 1172 moves to the specified position along with the inclination of the smoke machine body 11, the magnetic force detection device 1182 can obtain the inclination angle θ of the smoke machine body 11 when the corresponding magnetic force detection device 1182 is triggered. In addition, the movable ball 1172, the conduit 1171 and the magnetic force detection device 1182 are used in cooperation, which is simple in structure, convenient to use and small in size, can reduce the overall volume of the desktop smoke machine 1 and has great practicability.

[0064] Please continue to combine Figures 4-7As shown, specifically, the conduit 1171 is a V-shaped tube. By setting the conduit 1171 as a V-shaped tube, on one hand, it can correspond to the three states of the conventional state, excessive downward inclination and excessive upward inclination of the range hood body 11, and on the other hand, it can make the movable ball 1172 produce a collision sound when it moves to the three end points of the V-shaped tube following the inclination of the range hood body 11, further indicating the user that the inclination of the range hood body 11 is in place, and preventing excessive inclination.

[0065] More specifically, the conduit 1171 includes a first end 11711, a curved end 11712 and a second end 11713, and the curved end 11712 is located between the first end 11711 and the second end 11713. The magnetic force detection device 1182 includes a first magnetic force sensor 11821, a second magnetic force sensor 11822 and a third magnetic force sensor 11823, the first magnetic force sensor 11821 is arranged corresponding to the first end 11711, the second magnetic force sensor 11822 is arranged corresponding to the second end 11713, and the third magnetic force sensor 11823 is arranged corresponding to the curved end 11712. When the range hood body 11 is in the conventional state, the movable ball 1172 is located at the curved end 11712 and triggers the third magnetic force sensor 11823, when the range hood body 11 is inclined downward from the conventional state and the movable ball 1172 is located at the first end 11711, the first magnetic force sensor 11821 is triggered, and when the range hood body 11 is inclined upward from the conventional state and the movable ball 1172 is located at the second end 11713, the second magnetic force sensor 11822 is triggered.

[0066] Specifically, when the inclination angle θ of the range hood body 11 is 10-50 degrees, the movable ball 1172 is located at the curved end 11712, that is, the inclination angle θ of the range hood body 11 in the conventional state is 10-50 degrees. When the inclination angle θ of the range hood body 11 is greater than 50 degrees, the movable ball 1172 is located at the first end 11711, that is, when the inclination angle θ of the range hood body 11 is greater than 50 degrees, the range hood body 11 is excessively inclined downward, and oil stains are easy to drop onto the table top. When the inclination angle θ of the range hood body 11 is less than 10 degrees, the movable ball 1172 is located at the second end 11713, that is, when the inclination angle θ of the range hood body 11 is less than 10 degrees, the range hood body 11 is excessively inclined upward, and at this time, the smoke suction effect of the table top range hood 1 is poor.

[0067] In the embodiment of the present application, by matching the position of the movable ball 1172 in the conduit 1171 with the inclination angle θ of the range hood body 11, the corresponding magnetic force sensor is triggered for the table top range hood 1 in the three inclination states, and further, the table top range hood 1 is provided with a favorable environment for starting the corresponding operation mode.

[0068] In the embodiment of the present application, the conduit 1171 is defined with three end points, i.e., the first end 11711, the curved end 11712 and the second end 11713, which correspond to three states of the table-top range hood 1 respectively. The curved end 11712 between the first end 11711 and the second end 11713 can correspond to a normal state, i.e., a tilt angle θ corresponding to a normal use of the table-top range hood 1. The first end 11711 can correspond to a tilt angle θ corresponding to an excessive downward tilt from the normal state. The second end 11713 can correspond to a tilt angle θ corresponding to an excessive upward tilt from the normal state. In this way, when the movable ball 1172 moves to the first end 11711 or the second end 11713, i.e., the range hood body 11 is excessively tilted upward or downward, the movable ball 1172 triggers the corresponding magnetic force sensor, and the table-top range hood 1 is enabled to start the corresponding operation mode.

[0069] Referring to FIG. 1, Figure 8 As shown in FIG. 1, optionally, the curved angle a of the curved end 11712 is 90-125 degrees. Specifically, the curved angle a of the curved end 11712 is 90 degrees, 95 degrees, 100 degrees, 105 degrees, 110 degrees, 115 degrees, 120 degrees or 125 degrees. Preferably, in the embodiment of the present application, the curved angle a of the curved end 11712 is 115 degrees.

[0070] It can be understood that the curved angle a of the curved end 11712 is negatively correlated with the forward tilt angle of the range hood body 11. The greater the curved angle a, the easier the movable ball 1172 passes through the curved end 11712 of the conduit. Therefore, by limiting the curved angle a of the curved end 11712 to 90-125 degrees, it can be ensured that the movable ball 1172 smoothly passes through the curved end 11712 of the conduit 1171.

[0071] Optionally, the included angle b between the pipe section of the conduit 1171 where the second end 11713 is located and the horizontal plane is 0-15 degrees. Specifically, the included angle b is 0 degrees, 5 degrees, 7 degrees, 10 degrees or 15 degrees. Preferably, in the embodiment of the present application, the included angle b is 7 degrees.

[0072] It can be understood that the included angle b between the pipe section of the conduit 1171 where the second end 11713 is located and the horizontal plane adjusts and controls the range of the excessively small forward tilt angle of the range hood body 11, and is positively correlated. The greater the included angle b, the more the air inlet of the range hood body 11 is tilted upward. When the movable ball 1172 does not move to the second end 11713, the tilt angle θ of the range hood body 11 corresponds to a poor smoke suction effect, which is not conducive to smoking. Therefore, by limiting the included angle b between the pipe section of the conduit 1171 where the second end 11713 is located and the horizontal plane to 0-15 degrees, it can be ensured that the position of the movable ball 1172 in the conduit 1171 corresponds to the state of the range hood body 11, and the smoke suction effect of the table-top range hood 1 is improved.

[0073] Please refer toFigure 3 、 Figure 9 and Figure 10 As shown in FIG. 1, the table-type range hood 1 further comprises an assembly box 119 and an assembly cover 120. The assembly box 119 is arranged at the outer circumferential side of the fan 115 and between the fan 115 and the housing 111. The assembly box 119 is hollow, and the duct 1171 and the circuit board 1181 are arranged in the assembly box 119. The duct 1171 is open at one end and closed at the other end. The assembly cover 120 is arranged on the assembly box 119 and abuts the open end of the duct 1171. In this way, the duct 1171 and the circuit board 1181 are arranged in the assembly box, which can fix and protect the duct 1171 and the circuit board 1181. The duct 1171 is arranged to be open at one end and closed at the other end, which facilitates the installation of the movable ball 1172 in the duct. The assembly box 119 and the assembly cover 120 are arranged in cooperation, which facilitates the installation of the duct 1171 and the circuit board 1181 in the assembly box 119 for fixation. After the assembly cover 120 is arranged on the assembly box 119, it can abut the open end of the duct 1171, which prevents the movable ball 1172 from being separated from the duct 1171 during the tilting of the range hood main body 11.

[0074] Further, the assembly box 119 is arranged apart from the fan 115. In the embodiment of the present application, the assembly box 119 is arranged apart from the fan 115, which can avoid the displacement of the movable ball 1172 in the duct 1171 fixed in the assembly box 119 due to the vibration of the fan 115 during the normal operation of the table-type range hood 1, and thus affect the detection of the tilting angle θ of the range hood main body 11.

[0075] Any combination of the technical features of the above embodiments can be made. In order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, however, as long as the combinations of the technical features do not exist, they should be considered as the scope of the present application.

It should be pointed out that, for ordinary skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, which all belong to the protection scope of the present application.
