DETAILED DESCRIPTION

[0053] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0055] like Figure 1-Figure 10 As shown, in this embodiment, a device with a smoke collecting hood is provided, including a machine body 1, a smoke collecting hood 2, an anti-collision device and a controller.

[0056] The smoke hood 2 is movably connected to the body 1; the anti-collision device is connected to the smoke hood 2, and is suitable for sending a stop signal when the smoke hood 2 contacts an obstacle during the movement relative to the body 1; the controller is electrically connected to the anti-collision device, and is suitable for controlling the smoke hood 2 to stop moving when receiving the stop signal sent by the anti-collision device.

[0057] By setting up an anti-collision device connected to the smoke hood 2, when the smoke hood 2 contacts an obstacle during movement, the anti-collision device can send a stop signal. After receiving the stop signal, the controller promptly controls the smoke hood 2 to stop moving, thereby preventing damage to the obstacle and reducing the safety hazards of the smoke hood 2.

[0058] The device with the smoke hood in this embodiment further includes a driving device connected to the smoke hood 2, and the driving device is suitable for driving the smoke hood 2 to move relative to the machine body 1; the controller is electrically connected to the driving device, and is suitable for controlling the driving device to stop driving the smoke hood 2 to move when receiving a stop signal from the anti-collision device. By setting the driving device to drive the smoke hood 2 to move relative to the machine body 1 and electrically connected to the controller, when the smoke hood 2 encounters an obstacle during the movement, the controller can automatically control the driving device to drive the smoke hood 2 to stop moving, so that the smoke hood 2 stops more timely, thereby improving the intelligence of the device.

[0059] As a convertible implementation, it is also possible that the driving device is not included, and a person manually drives the smoke hood 2 to move relative to the body 1. When the controller receives a stop signal from the anti-collision device, it sends an alarm signal (such as voice or light or a combination of the two), thereby allowing the person to manually control the smoke hood 2 to stop moving.

[0060] The biasing member in this embodiment is a spring 3. As a convertible implementation, the biasing member can also be a biasing member of other forms.

[0061] The anti-collision device in this embodiment includes: a spring 3, one end of which is connected to the smoke hood 2, and the other end of which is connected to the driving device; a trigger device, which is suitable for sending a stop signal when the smoke hood 2 contacts an obstacle during the movement relative to the machine body 1. The anti-collision device is configured to include the spring 3 and the trigger device, so that when the smoke hood 2 moves relative to the machine body 1 and encounters an obstacle, the driving device can drive the spring 3 to continue to move, such as when the spring 3 continues to be compressed or stretched, the bias force of the spring 3 will trigger the trigger device and send a stop signal, so that the controller can control the smoke hood 2 to stop moving in time.

[0062] Specifically, Figure 1-Figure 6 As shown, the trigger device in this embodiment includes a paddle 5, which is arranged on the driving device; at least one micro switch 6, which is arranged on the smoke hood 2. When the paddle 5 contacts the micro switch 6, the trigger device sends a stop signal. By arranging the paddle 5 on the driving device and at least one micro switch 6 on the smoke hood 2, when the smoke hood 2 moves in at least one direction, when it encounters an obstacle in the direction, the smoke hood 2 stops moving, and the driving device can continue to move with the spring 3, so that the paddle 5 contacts the micro switch 6, and then sends a stop signal. The triggering method is relatively simple. As a convertible embodiment, it is also possible that the paddle 5 is arranged on the smoke hood 2 and the micro switch 6 is arranged on the driving device.

[0063] In order to improve the reliability of the movement of the smoke hood 2, the trigger device in this embodiment includes two micro switches 6 arranged at intervals, and the paddle 5 is located between the two micro switches 6. By including the trigger device with two micro switches 6 arranged at intervals, when the smoke hood 2 moves in two different directions and encounters an obstacle, the paddle 5 can contact the micro switch 6, thereby ensuring the reliability of the smoke hood 2 moving in different directions.

[0064] In this embodiment, a fixing seat 7 is provided on the smoke collecting hood 2 , a micro switch 6 is provided on the fixing seat 7 , and the spring 3 is connected to the smoke collecting hood 2 by connecting to the fixing seat 7 .

[0065] like Figure 7-Figure 9As shown, another form of trigger device is also provided in this embodiment, and the trigger device includes two displacement sensors 8, which are arranged on the driving device, one of which is initially in a normally open state, and the other is initially in a normally closed state. Specifically, a support member 9 is provided on the driving device, and the displacement sensor 8 is provided on the support member 9, and the spring 3 is connected to the driving device through the support member 9. When the smoke hood 2 encounters an obstacle during movement, the spring 3 continues to stretch, so that the two displacement sensors 8 are both in an open state (that is, the smoke hood 2 is out of contact with the displacement sensor 8), and the controller controls the smoke hood 2 to stop moving; the spring 3 continues to compress, so that the two displacement sensors 8 are both in a closed state (that is, the smoke hood 2 is in contact with the displacement sensor 8), and the controller controls the smoke hood 2 to stop moving. As a convertible embodiment, it is also possible that the displacement sensor 8 is provided on the smoke hood 2.

[0066] The device with the smoke hood in this embodiment is not provided with a guide member. As a convertible implementation, the device with the smoke hood may also include a guide member, which is arranged inside the spring 3. Specifically, the guide member in this embodiment includes a guide column 21, which is arranged inside the spring 3. The guide column 21 is fixed to the driving device through a guide screw 22. By arranging the guide member inside the spring 3, the spring 3 can be better guided during the movement of the spring 3, thereby preventing the spring 3 from deflecting during the movement.

[0067] The driving device in this embodiment includes: a power device; a transmission mechanism connected to the power device and the spring 3, and adapted to drive the spring 3 and the smoke collecting hood 2 to move under the drive of the power device. Figure 3 As shown, the power device in this embodiment is a push rod motor 10, including a motor body 19 and a push rod 18, and the transmission mechanism includes a slider 11, which is movably connected to the push rod 18. Driven by the motor body 19, the slider 11 reciprocates on the push rod 18. As a convertible implementation, it can also be, Fig. 9 As shown, the power device is a motor 24 , and the transmission structure includes a slider 11 and a screw 20 .

[0068] Specifically, Figure 1-Figure 3 As shown, the slider 11 in this embodiment is arranged below the fixing seat 7, one end of the spring 3 is connected to the slider 11, and the other end is connected to the top of the fixing seat 7, and the top of the fixing seat 7 is fixedly connected to the bottom of the smoke hood 2. As a convertible embodiment, it can also be, Figure 4 As shown, the fixing seat 7 is arranged on the smoke hood 2, and a clearance hole 23 is provided on the fixing seat 7. One end of the spring 3 is connected to the slider 11, and the other end is connected to the bottom of the smoke hood 2. The slider 11, driven by the push rod motor 10, can pass through the clearance hole 23 on the fixing seat 7 to drive the spring 3 and then drive the smoke hood 2 to perform lifting and lowering movements.

[0069] The smoke collecting hood 2 in this embodiment moves up and down along the machine body 1. Figure 5 and Figure 6 As shown, in this embodiment, a limiting cavity 12 is provided on the machine body 1, a smoke hood 2 is provided in the limiting cavity 12, a guide rail 15 is provided in the limiting cavity 12, and a convex block 16 cooperating with the guide rail 15 is provided on the smoke hood 2, so that the smoke hood 2 can move up and down relative to the machine body 1 in the limiting cavity 12. When the smoke hood 2 is not in use, a first flange 13 extends outward from the top of the limiting cavity 12, and a second flange 14 extends outward from the top of the smoke hood 2. When the first flange 13 contacts the second flange 14, the smoke hood 2 moves to the lower limit position. By setting a first flange 13 on the top of the limiting cavity 12 and a second flange 14 on the top of the smoke hood 2, when the first flange 13 contacts the second flange 14, the smoke hood 2 moves to the lower limit position, at which time the smoke hood 2 can be completely in the limiting cavity 12, making the overall appearance of the device more beautiful and increasing the use space of the device surface; when the smoke hood 2 needs to be used, a closed end 17 is provided on the top of the guide rail 15, and when the protrusion 16 moves to the closed end 17, the smoke hood 2 moves to the upper limit position. As a convertible embodiment, it is also possible to set a protrusion 16 in the limiting cavity 12 and set a guide rail 15 on the smoke hood 2.

[0070] like Fig.10 As shown, the device with a smoke hood in this embodiment is an integrated stove, including a stove 4, a body 1 and a smoke hood 2. As a convertible embodiment, the device with a smoke hood can also be another device with a smoke hood, and the smoke hood 2 can achieve lifting movement relative to the body 1.

[0071] When the integrated stove does not need to work, the smoke hood 2 moves downward relative to the body 1. During the descending process, the spring 3 is in a semi-compressed state. At this time, the paddle 5 on the slider 11 is between the two micro switches 6. The elastic force of the spring 3 is equal to the gravity of the smoke hood 2. The push rod motor 10 drives the slider 11 to drive the spring 3, and then drives the smoke hood 2 to move downward. When encountering an obstacle, the obstacle prevents the smoke hood 2 from moving downward. The push rod motor 10 drives the slider 11 to drive the spring 3 to continue moving downward. When the paddle 5 on the slider 11 touches the lower micro switch 6, a stop signal is issued, and the controller controls the push rod motor 10 to stop moving, thereby stopping the smoke hood 2 from moving. When the smoke hood 2 needs to work, The smoke hood 2 moves upward relative to the body 1. During the upward process, the spring 3 is in a semi-compressed state. At this time, the paddle 5 on the slider 11 is between the two micro switches 6. The elastic force of the spring 3 is equal to the gravity of the smoke hood 2. The push rod motor 10 drives the slider 11 to drive the spring 3, and then drives the smoke hood 2 to move upward. When encountering an obstacle, the obstacle prevents the smoke hood 2 from moving upward. The push rod motor 10 drives the slider 11 to drive the spring 3 to continue to move upward. When the paddle 5 on the slider 11 touches the upper micro switch 6, a stop signal is sent, and the controller controls the push rod motor 10 to stop moving, thereby stopping the smoke hood 2 from moving to prevent damage to the obstacle and preventing the smoke hood 2 from being damaged by the obstacle.

[0072] For another form of trigger device, when the smoke hood 2 moves downward relative to the body 1, the spring 3 is in a semi-compressed state, and the elastic force of the spring 3 is equal to the gravity of the smoke hood 2. At this time, the displacement sensors 8 on the support sheet, one of the displacement sensors 8 is initially in a normally open state (that is, the top of the displacement sensor 8 is in a separated state from the smoke hood 2), and the other displacement sensor 8 is initially in a normally closed state (that is, the top of the displacement sensor 8 is in a contact state with the smoke hood 2). The motor 24 drives the slider 11 to move up and down on the screw rod 20, and the slider 11 drives the spring 3, thereby driving the smoke hood 2 to move downward. When encountering an obstacle, the obstacle prevents the smoke hood 2 from moving downward, and the motor 24 drives the slider 11 to drive the spring 3 to continue to move downward. When the displacement sensor 8 in the normally closed state is out of contact with the smoke hood 2 and is in a separated state, the two displacement sensors 8 are both in an open state, and a stop signal is sent out. The controller controls the motor 24 to stop moving, thereby causing the smoke hood 2 to stop moving. When the smoke hood 2 moves upward relative to the body 1, the spring 3 is in a semi-compressed state, and the elastic force of the spring 3 is equal to the gravity of the smoke hood 2. At this time, one of the displacement sensors 8 on the support plate is initially in a normally open state (that is, the top of the displacement sensor 8 is separated from the smoke hood 2), and the other displacement sensor 8 is initially in a normally closed state (that is, the top of the displacement sensor 8 is in contact with the smoke hood 2). The motor 24 drives the slider 11 to move upward on the screw 20, and the slider 11 drives the spring 3, thereby driving the smoke hood 2 to move upward. When encountering an obstacle, the obstacle prevents the smoke hood 2 from moving upward, and the motor 24 drives the slider 11 to drive the spring 3 to continue to move upward. When the displacement sensor 8 in the normally open state contacts the smoke hood 2, the two displacement sensors 8 are in a closed state and send out a stop signal. The controller controls the motor 24 to stop moving, thereby stopping the smoke hood 2 from moving, preventing damage to the obstacle and preventing the smoke hood 2 from being damaged by the obstacle.

[0073] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
