[0002] A range hood is a kitchen appliance used in home kitchens to remove cooking fumes.

[0003] Currently, household range hoods are fixed to the wall by hanging them on hooks and then using expansion screws. This means the position of the range hood is fixed and its height cannot be changed. This cannot meet the needs of users of different heights to find a range hood that is the right height for them, increasing the inconvenience of using the range hood and also causing some damage to the wall. Summary of the Invention

[0004] To address at least one of the aforementioned technical problems, this application proposes a range hood lifting device and control method.

[0005] According to one aspect of this application, a range hood lifting device is disclosed. The device includes a range hood, a floating component, and a hydraulic drive device. The range hood is connected to the floating component via a first fixed structure. The floating component is disposed at one end of the hydraulic drive device. The hydraulic drive device is used to drive the floating component to move up and down. The floating component is used to drive the range hood to rise or fall.

[0006] In some possible implementations, the hydraulic drive includes a connector filled with liquid, and a floating assembly disposed at the end of the connector away from the ground, the floating assembly moving in response to changes in the pressure of the liquid.

[0007] In some possible implementations, the hydraulic drive device further includes a hydraulic drive assembly for regulating the pressure of the fluid within the connector.

[0008] In some possible implementations, the hydraulic drive assembly includes a pedal and a power plate. The pedal is disposed at one end of the connector near the ground, and the power plate is connected to the pedal. The hydraulic drive assembly is used to generate power in a preset direction based on the pressure transmitted by the pedal and the force generated by the power plate, thereby adjusting the pressure of the liquid within the connector.

[0009] In some possible implementations, the connector includes a limiting plate and a limiting groove, the floating component is disposed within the limiting plate, the limiting plate is used to keep the movement range of the floating component within a preset range; the limiting groove is disposed at preset intervals in the vertical direction of the inner edge of the connector; the limiting groove is used to fix the floating component.

[0010] In some possible implementations, the device further includes a shock-absorbing structure connected to the range hood via a second fixing structure, the shock-absorbing structure being used to absorb vibrations from the range hood.

[0011] In some possible implementations, the shock-absorbing structure includes a shock-absorbing plate and a raised structure. The shock-absorbing plate is connected to the range hood via the second fixing structure. The raised structure is disposed on the left and right sides of the shock-absorbing plate relative to the side of the shock-absorbing plate connected to the range hood. The shock-absorbing plate is connected to the floating component via the raised structure.

[0012] In some possible implementations, the floating assembly includes a float plate disposed at the end of the connector away from the ground, with the edge of the float plate abutting against the inner edge of the connector; a limiting piece is provided at the edge of the float plate near the ground; the float plate is used to drive the range hood to rise or fall; the limiting piece is used to fix the float plate in a limiting groove.

[0013] According to another aspect of this application, a range hood lifting control method is also disclosed, applied to the aforementioned range hood lifting device, the method comprising:

[0014] Obtain the ideal and actual height of the range hood;

[0015] Based on the ideal height and the actual height, determine the target height difference of the range hood;

[0016] When the target height difference is greater than the preset height difference, the hydraulic drive device is controlled to drive the floating component to move upward, so that the floating component drives the range hood to rise.

[0017] If the target height difference is less than the preset height difference, the hydraulic drive device is controlled to drive the floating component to move downward, so that the floating component drives the range hood to descend.

[0018] In some possible implementations, controlling the hydraulic drive device to drive the floating component upward when the target height difference is greater than a preset height difference, so that the floating component drives the range hood to rise, includes:

[0019] When the target height difference is greater than the preset height difference, the hydraulic drive assembly is controlled to generate downward force to increase the pressure of the liquid inside the connector.

[0020] The increased pressure of the liquid inside the connector drives the float to move upward, thereby causing the float to lift the range hood.

[0021] In some possible implementations, controlling the hydraulic drive device to drive the floating component downward when the target height difference is less than a preset height difference, so that the floating component causes the range hood to descend, includes:

[0022] When the target height difference is less than the preset height difference, the hydraulic drive assembly is controlled to generate upward force to reduce the pressure of the liquid inside the connector.

[0023] The reduced pressure of the liquid inside the connector drives the float to move downwards, causing the float to lower the range hood.

[0024] Due to the above technical solution, this application has the following beneficial effects:

[0025] The range hood lifting device in this embodiment is connected to the range hood via a floating component. When the hydraulic drive device moves the floating component up and down, the floating component causes the range hood to rise or fall, allowing the range hood to be raised and lowered to meet the different height requirements of users of different heights and improve the user experience. The range hood also reduces energy consumption by rising or falling with the movement of the floating component. Furthermore, the connection between the range hood and the floating component avoids damage to the wall surface caused by directly hanging the range hood on the wall. Attached Figure Description

[0039] Figure 1 This is a schematic diagram of a range hood lifting device provided in an embodiment of this application; as shown Figure 1 As shown, the device includes a range hood 10, a floating component 20, and a hydraulic drive device 30. The range hood 10 is connected to the floating component 20 through a first fixed structure. The floating component 20 is disposed at one end of the hydraulic drive device 30. The hydraulic drive device 30 is used to drive the floating component 20 to move up and down. The floating component 20 is used to drive the range hood 10 to rise or fall.

[0040] In this embodiment, the range hood 10 is connected to the floating component 20 via a first fixing structure. The first fixing structure is used to fix the range hood 10 to the floating component 20. Optionally, the first fixing structure includes, but is not limited to, bolts, nuts, or screws. The hydraulic drive device 30 can be various types of hydraulic drive devices, including, but not limited to, drive devices capable of generating pressure. The floating component 20 can be various types of floating components, including, but not limited to, floating plates.

[0041] In this embodiment, the range hood 10 is fixedly connected to the floating assembly 20. When the hydraulic drive device 30 drives the floating assembly 20 to move up and down, the floating assembly 20 can cause the range hood 10 to rise or fall, allowing the range hood to be raised and lowered to meet the different height requirements of users of different heights and improve the user experience. Because the range hood 10 is connected to the floating assembly 20, damage to the wall caused by directly hanging the range hood on the wall is avoided. The fact that the range hood 10 rises or falls with the up and down movement of the floating assembly 20 also reduces energy consumption.

[0042] Figure 2 This is a schematic diagram of another range hood lifting device provided in the embodiments of this application. Figure 1 ;likeFigure 2 As shown, the hydraulic drive device 30 includes a connector 31 filled with liquid, and a floating component 20 disposed at the end of the connector 31 away from the ground. The floating component 20 moves with the change in the pressure of the liquid.

[0043] In this embodiment, the connector 31 is filled with liquid, which, exemplarily, includes, but is not limited to, water. A floating component 20 is disposed at the end of the connector 31 away from the ground, and the area of ​​the bottom of the floating component 20 is the same as the planar area of ​​one end region of the connector 31, thus sealing the end of the connector 31 away from the ground. Furthermore, the end of the connector 31 near the ground is also sealed, making the connector 31 a sealed structure. Exemplarily, the connector 31 includes, but is not limited to, a U-shaped closed container.

[0044] The floating component 20 is located at one end of the enclosed connector 31. The floating component 20 can move in response to changes in the pressure of the liquid within the connector 31. When the pressure of the liquid within the connector 31 increases, due to the fluidity of the liquid, the pressure is transmitted in all directions within the connector 31, reaching the bottom of the floating component 20. This generates an upward thrust on the floating component 20, causing it to move upwards and lifting the range hood 10. When the pressure of the liquid within the connector 31 decreases, the floating component 20 and the range hood move downwards due to gravity, causing the range hood 10 to descend. Thus, the range hood 10 can rise or fall with the up-and-down movement of the floating component 20, meeting the different height requirements of users of different heights and improving the user experience. Furthermore, utilizing the pressure transmission of the liquid to move the floating component 20 reduces energy consumption.

[0045] In an optional embodiment, the hydraulic drive device 30 further includes a hydraulic drive assembly 32 for adjusting the pressure of the liquid within the connector 31.

[0046] In this embodiment, the hydraulic drive device 30 further includes a hydraulic drive assembly 32. The hydraulic drive assembly 32 can be of various types; for example, it may include, but is not limited to, a drive assembly capable of changing the pressure of the liquid within the connector. Optionally, the hydraulic drive assembly 32 can be located at the end of the connector 31 closest to the ground and at the end furthest from the floating assembly 20. The hydraulic drive assembly 32 can adjust the pressure of the liquid within the connector 31, thereby causing the floating assembly 20 to move as the liquid pressure changes.

[0047] In an optional embodiment, the hydraulic drive assembly 32 includes a pedal and a power plate. The pedal is disposed at one end of the connector 31 near the ground, and the power plate is connected to the pedal. The hydraulic drive assembly 32 is used to generate power in a preset direction based on the pressure transmitted by the pedal and the force generated by the power plate, thereby adjusting the pressure of the liquid in the connector 31.

[0048] In this embodiment, the hydraulic drive assembly 32 includes a pedal disposed at the end of the connector 31 near the ground. The pedal can receive the user's weight. The pedal is connected to a power plate and can receive the force generated by the power plate. The hydraulic drive assembly 32 can generate a force in a preset direction based on the pressure transmitted by the pedal and the force generated by the power plate, thereby adjusting the pressure of the liquid within the connector 31. The pressure transmitted by the pedal is the user's weight received by the pedal. Therefore, the hydraulic drive assembly 32 can generate a force in a preset direction based on the user's weight received by the pedal and the force generated by the power plate received by the pedal, thereby adjusting the pressure of the liquid within the connector 31. For example, when the combined force of the pressure transmitted by the pedal and the force generated by the power plate is downward, the hydraulic drive assembly generates a downward force, increasing the pressure of the liquid inside the connector and increasing the upward force of the liquid below the floating assembly, thereby generating an upward force on the floating assembly, causing the floating assembly to move upward and drive the range hood to rise; when the combined force of the pressure transmitted by the pedal and the force generated by the power plate is upward, the hydraulic drive assembly generates an upward force, increasing the downward force of the liquid below the floating assembly, decreasing the pressure of the liquid inside the connector, thereby reducing the force on the floating assembly, causing the floating assembly to move downward and drive the range hood to descend.

[0049] Optionally, Figure 4 This is a schematic diagram of the hydraulic drive device provided in the embodiments of this application, such as... Figure 4As shown, the power plate includes, but is not limited to, the small float 321. A pressure sensor is installed at the pedal, which monitors the force generated by the hydraulic drive assembly. This force is either the resultant force of the pressure transmitted by the pedal and the force generated by the power plate, or the resultant force of the user's weight received by the pedal and the force generated by the power plate, or the resultant force of the user's weight received by the pressure sensor and the force generated by the power plate. The pressure sensor is connected to the power plate. In this embodiment, the pressure sensor is connected to the small float via a spring. Using Pascal's law, the pressure at the pressure sensor is the same as the pressure at the small float. Therefore, the change in the force generated by the small float can be achieved by changing the contact area between the small float and the liquid. As the contact area increases, the force at the small float also increases. The magnitude of the force generated by the small float received by the pressure sensor can be determined by the number of small floats connected to the pressure sensor, which is determined based on the actual situation. For example, when the number of small floats connected to the pressure sensor increases, the contact area between the small floats connected to the pressure sensor and the liquid increases, thus increasing the force at the small floats and the force received by the pressure sensor from the small floats; when the number of small floats connected to the pressure sensor decreases, the contact area between the small floats connected to the pressure sensor and the liquid decreases, thus decreasing the force at the small floats and the force received by the pressure sensor from the small floats; when the pressure sensor is not connected to any small floats, the pressure sensor only receives the user's gravity.

[0050] In this embodiment, the force generated by the power plate is used to assist the pedal in receiving the user's weight, thereby enabling the hydraulic drive assembly to generate a force capable of adjusting the pressure of the liquid within the connector. For example, when it is necessary for the force generated by the hydraulic drive assembly to increase the pressure of the liquid within the connector, but the user's weight received by the pedal is less than the force required to increase the pressure within the connector, the force generated by the power plate needs to be increased to ensure that the force generated by the hydraulic drive assembly can increase the pressure of the liquid within the connector. Conversely, when it is necessary for the force generated by the hydraulic drive assembly to decrease the pressure of the liquid within the connector, but the user's weight received by the pedal is greater than the force required to decrease the pressure within the connector, the force generated by the power plate needs to be increased to offset part of the weight, so that the force generated by the hydraulic drive assembly can decrease the pressure of the liquid within the connector. The specific process of the change in the force generated by the hydraulic drive assembly is analyzed based on the actual situation.

[0051] In an optional embodiment, the connector 31 includes a limiting plate 311 and a limiting groove. The floating component 20 is disposed within the limiting plate 311. The limiting plate 311 is used to keep the moving range of the floating component 20 within a preset range. The limiting groove is disposed at preset intervals in the vertical direction of the inner edge of the connector 31. The limiting groove is used to fix the floating component 20.

[0052] In this embodiment, the connector 31 includes a limiting plate 311, and the floating component 20 is disposed within the limiting plate 311. The limiting plate 311 can keep the movement range of the floating component 20 within a preset range, preventing the floating component 20 from moving upward or downward without restriction. Optionally, the end of the limiting plate 311 that prevents the floating component 20 from moving downward without restriction is hollow in the middle, facilitating liquid flow to the floating component 20. The connector 31 also includes a limiting groove, which is disposed at preset intervals in the vertical direction of the inner edge of the connector 31. The limiting groove can fix the floating component 20. For example, when the floating component 20 moves to a suitable position, it is locked in the limiting groove to prevent the floating component 20 from moving further.

[0053] In an optional embodiment, the device further includes a shock-absorbing structure 40 connected to the range hood 10 via a second fixing structure, the shock-absorbing structure 40 being used to absorb the vibration of the range hood 10.

[0054] In this embodiment, the range hood lifting device further includes a shock-absorbing structure 40, which is connected to the range hood 10 via a second fixing structure. Exemplarily, the second fixing structure includes screws and hooks. The shock-absorbing structure 40 can absorb the vibration of the range hood 10, thereby reducing the vibration of the range hood to the wall and lowering noise. Fixing the range hood 10 to the shock-absorbing structure 40 can prevent damage to the wall surface when the range hood is hung on it.

[0055] In an optional embodiment, the shock-absorbing structure 40 includes a shock-absorbing plate 41 and a raised structure 42. The shock-absorbing plate 41 is connected to the range hood 10 via the second fixing structure. The raised structure 42 is disposed on the left and right sides of the shock-absorbing plate 41 relative to the side of the shock-absorbing plate 41 connected to the range hood 10. The shock-absorbing plate 41 is connected to the floating component 20 via the raised structure 42.

[0056] In this embodiment, the vibration damping structure 40 includes a vibration damping plate 41, which is connected to the range hood 10 via a second fixing structure. Optionally, the surface of the vibration damping plate 41 is an elastic material covering a high-strength plastic part, including rubber, both of which are flame-retardant and fireproof. The interior of the vibration damping plate 41 is a porous absorbent sponge. Furthermore, the area of ​​the vibration damping plate 41 essentially covers the back area of ​​the range hood. The vibration damping plate 41 can absorb the vibration of the range hood, reducing vibration to the wall and lowering noise. The surfaces of the vibration damping plate 41 and the connector 31 can be painted with corresponding colors according to individual needs, thereby improving the aesthetics of the range hood's operating environment.

[0057] In this embodiment, the shock-absorbing structure 40 further includes a protruding structure 42. The protruding structure 42 is provided on the left and right sides of the shock-absorbing plate 41, and on the side of the shock-absorbing plate 41 that is connected to the range hood 10. The shock-absorbing plate 41 is connected to the floating component 20 through the protruding structure 42. When the floating component 20 moves up and down, the shock-absorbing plate 41 moves up and down with the floating component 20, causing the range hood 10 to rise or fall. Optionally, the protruding structure 42 can be of various types.

[0058] In an optional embodiment, the floating assembly 20 includes a float 21 disposed at the end of the connector 31 away from the ground, and the edge of the float 21 is in contact with the inner edge of the connector 31; a limiting piece is provided at the edge of the end of the float 21 near the ground; the float 21 is used to drive the range hood 10 to rise or fall; the limiting piece is used to fix the float 21 in the limiting groove.

[0059] In this embodiment, the floating assembly 20 includes a float plate 21, which is disposed at the end of the connector 31 away from the ground. The edge of the float plate 21 is abutted against the inner edge of the connector 31, sealing this section of the connector away from the ground. A limiting plate is provided around the periphery of the end of the float plate 21 near the ground. Optionally, the limiting plate can pop out from the float plate 21 or retract into the float plate 21. The float plate 21 can be fixed to the connector 31 by being engaged in a limiting groove by the limiting plate. Exemplarily, when the float plate 21 moves to a suitable position, the limiting plate pops out from the float plate 21 and engages in the limiting groove of the connector 31, thereby fixing the float plate 21 to the connector; when the limiting plate pops out from the limiting groove and retracts into the float plate 21, the float plate 21 can move.

[0060] In the embodiments of this application, Figure 3 This is a schematic diagram of another range hood lifting device provided in the embodiments of this application. Figure 2 ;like Figure 3 As shown, the stove 60 can be installed on the connector 31, and the floor 50 can be installed in the empty space. A channel can be installed under the stove 60 and the floor 50 to connect the two ends of the connector.

[0061] In this embodiment, a scale can be set on the connector along the vertical direction, and an identification component can be set at the bottom of the shock-absorbing plate. The scale can be identified by the identification component to determine the actual height of the bottom of the range hood from the stove surface.

[0062] Figure 5 This is a flowchart illustrating a range hood lifting control method provided in an embodiment of this application; the range hood lifting control method is applied to the aforementioned range hood lifting device, such as... Figure 5 As shown, the method includes:

[0063] Step S501: Obtain the ideal height and actual height of the range hood;

[0064] In this embodiment, the ideal height of the range hood is the ideal height of the bottom of the range hood from the ground to accommodate the user's height, thus facilitating user use; the actual height of the range hood is the actual height of the bottom of the range hood from the ground.

[0065] The methods for obtaining the ideal and actual height of the range hood include: a pressure sensor receiving the user's weight while the user stands on the footrest; obtaining the user's standard weight based on this weight, which corresponds to a standard body weight; and then, based on the user's standard body weight, determining the ideal and actual height of the range hood according to h. 人 =m 人标 +105, determine the user's height; based on the user's height, according to h 灶台面 =h 人 -80, determine the height of the top of the stove, i.e., the height of the stove surface from the ground; therefore, based on h 理想油烟机底部 =h 灶台面 +(A~B)=h 人 -80 + (A~B) = m 人标 +25+(A~B) determines the ideal height of the range hood, i.e., the ideal height of the bottom of the range hood from the ground. Here, A~B correspond to the ideal height range of the bottom of different range hood models from the cooktop surface. In this embodiment, a scale can be set along the vertical direction on the connector, and an identification component can be set at the bottom of the shock-absorbing plate. This identification component identifies the scale to obtain the actual height of the range hood, i.e., the actual height h of the bottom of the range hood from the cooktop surface. 实际油烟机底部 .

[0066] Step S502: Based on the ideal height and the actual height, determine the target height difference of the range hood;

[0067] In this embodiment of the application, based on the ideal height of the range hood and the actual height of the range hood, according to L=h 理想油烟机底部 -h 实际油烟机底部 Determine the target height difference for the range hood.

[0068] Step S503: When the target height difference is greater than the preset height difference, control the hydraulic drive device to drive the floating component to move upward, so that the floating component drives the range hood to rise;

[0069] In this embodiment, if the target height difference of the range hood is greater than the preset height difference, it indicates that the actual height of the range hood is too low and does not meet the user's height requirements for the range hood. Therefore, the range hood needs to be raised to meet the user's needs. Thus, the hydraulic drive device is controlled to drive the floating component to move upward, thereby driving the shock absorption structure to move upward and thus raising the range hood.

[0070] In an optional embodiment, the range hood remains stationary when the target height difference is equal to a preset height difference.

[0071] In this embodiment, if the target height of the range hood is equal to the preset height difference of the range hood, it means that the range hood does not need to be raised or lowered, and the range hood remains stationary.

[0072] Step S504: If the target height difference is less than the preset height difference, control the hydraulic drive device to drive the floating component to move downward, so that the floating component drives the range hood to descend.

[0073] In this embodiment, if the target height difference of the range hood is less than the preset height difference, it indicates that the actual height of the range hood is too high and does not meet the user's height requirements for the range hood. Therefore, the range hood needs to be lowered to meet the user's needs. Thus, the hydraulic drive device is controlled to drive the floating component to move downward, thereby causing the shock absorption structure to move downward and thus driving the range hood to descend.

[0074] In an optional embodiment, the step of controlling the hydraulic drive device to drive the floating component to move upward when the target height difference is greater than a preset height difference, so that the floating component drives the range hood to rise, includes:

[0075] When the target height difference is greater than the preset height difference, the hydraulic drive assembly is controlled to generate downward force to increase the pressure of the liquid inside the connector.

[0076] The increased pressure of the liquid inside the connector drives the float to move upward, thereby causing the float to lift the range hood.

[0077] In this embodiment, when the target height difference of the range hood is greater than the preset height difference, the hydraulic drive component is controlled to generate downward force, which increases the pressure of the liquid in the connector, thereby driving the float to move upward, driving the shock absorber to move upward, and thus driving the range hood to rise.

[0078] According to m 重 =m 浮板 +m 减震板 +m 油烟机Determine the total weight of the structure to be raised, and to ensure the safety of the range hood's movement, the range hood's speed range is 0 ≤ v ≤ 2 m / s. The target height difference of the range hood is L. Controlling the hydraulic drive assembly to generate downward force to drive the float plate upward includes: controlling the float plate's limiting plate to pop out from the limiting groove in the connector and retract. The range hood needs to rise by L. The range hood's movement process requires first uniformly accelerated linear motion until the speed reaches v, denoted as t1. According to F... 浮 -m 重 g = m 重 *v / t1 determines the forces acting on the range hood during its movement. According to Pascal's Law, if the float at one end of the connector (the range hood) needs to move upwards with uniform acceleration, then the internal plate at the pressure sensor at the other end of the connector needs to move downwards with uniform acceleration. The net force F required at the pressure sensor at this point is... 压力传感器 Downward, the force at the pressure sensor, i.e., the resultant force at the pressure sensor, is the power generated by the hydraulic drive assembly. The pressure transmitted by the pedal is obtained, which is the user's weight m. 人实 g, compared to F 压力传感器 and m 人实 g.

[0079] In F 压力传感器 ≥m 人实 In case g, it means the user's gravity does not meet the net force required at the pressure sensor. Therefore, the pressure sensor is controlled to increase the number of connected small floats to increase the downward force, with a magnitude of F. 压力传感器 -m 人实 g, so that the actual resultant force at the pressure sensor meets the resultant force required at the pressure sensor, and the direction of the resultant force at the pressure sensor is downward. At this time, the range hood accelerates upward in a straight line.

[0080] In F 压力传感器 <m 人实 In case g, it indicates that the user's gravity is too great, meaning the downward force provided by gravity is too large and does not meet the net force required at the pressure sensor. Therefore, the pressure sensor is controlled to reduce the number of connected small floats to increase the upward force, with a magnitude of F. 压力传感器 -m 人实 g partially offsets the downward force of gravity, ensuring that the actual net force at the pressure sensor meets the required net force. The direction of the net force at the pressure sensor is downward, causing the range hood to accelerate upward in a straight line.

[0081] Then, the range hood needs to move at a constant linear speed, denoted as v, until it begins to decelerate uniformly, denoted as t2. When the range hood needs to move upwards at a constant speed, F... 浮 =m 重 According to Pascal's law, the internal plate at the pressure sensor needs to descend at a constant speed in a straight line, and F 压力传感器=0, because the pressure sensor is subjected to the pressure transmitted from the pedal, i.e., the user's weight, an upward force of magnitude m needs to be added to the pressure sensor. 人实 g, so that the actual resultant force at the pressure sensor meets the resultant force required at the pressure sensor, at which point the range hood rises in a straight line at a uniform speed.

[0082] Finally, the range hood needs to decelerate linearly until its speed reaches 0, denoted as t3. The range hood rises a total of L, according to m 重 gF 浮 =m 重 *v / (t3-t2) determines the forces acting on the range hood during its motion. When the range hood needs to move upward in a uniformly decelerated linear motion, according to Pascal's law, the internal plate at the pressure sensor needs to move downward in a uniformly decelerated linear motion. Therefore, the net force at the pressure sensor needs to be upward, increasing the upward force by magnitude F. 压力传感器 -m 人实 g, so that the actual resultant force at the pressure sensor meets the resultant force required at the pressure sensor, at which point the range hood decelerates and rises in a linear motion.

[0083] The range hood moves upward in a straight line with uniform deceleration until it stops. While the range hood remains stationary, the limiting plate of the control float pops out and into the limiting groove of the connector to fix the float, keeping the range hood in place. This allows for convenient and normal use of the range hood.

[0084] In an optional embodiment, the step of controlling the hydraulic drive device to drive the floating component downward when the target height difference is less than a preset height difference, so that the floating component causes the range hood to descend, includes:

[0085] When the target height difference is less than the preset height difference, the hydraulic drive assembly is controlled to generate upward force to reduce the pressure of the liquid inside the connector.

[0086] The reduced pressure of the liquid inside the connector drives the float to move downwards, causing the float to lower the range hood.

[0087] In this embodiment, when the target height difference of the range hood is less than the preset height difference, the hydraulic drive component is controlled to generate upward force, thereby reducing the pressure of the liquid in the connector, which drives the float to move downward, drives the shock absorber to move downward, and causes the range hood to descend.

[0088] In this embodiment, when the target height difference of the range hood is less than the preset height difference, the hydraulic drive component is controlled to generate upward force, thereby reducing the pressure of the liquid in the connector, which drives the float to move downward, drives the shock absorber to move downward, and causes the range hood to descend.

[0089] Controlling the hydraulic drive assembly to generate upward force and drive the float to move downward includes: controlling the float's limiting plate to pop out from the limiting groove in the connector and retract; the range hood needs to descend by L; the range hood's movement process requires first uniformly accelerated linear motion until the speed reaches v, denoted as t4, according to m 重 gF 浮 =m 重 *v / t4 determines the forces acting on the range hood during its movement. According to Pascal's Law, if the floating plate at one end of the connector (the range hood) needs to descend with uniform acceleration, then the internal plate at the pressure sensor at the other end of the connector needs to ascend with uniform acceleration. The net force F required at the pressure sensor at this point is... 压力传感器 Upward, because the pressure sensor receives pressure transmitted from the pedal, i.e., the user's weight, an upward force of magnitude F needs to be added to the pressure sensor. 压力传感器 -m 人实 g, so that the actual resultant force at the pressure sensor meets the resultant force required at the pressure sensor, at which point the range hood accelerates downward in a straight line.

[0090] Then, the range hood needs to move at a constant linear speed, denoted as v, until it begins to decelerate uniformly, denoted as t5. When the range hood needs to descend at a constant linear speed, F... 浮 =m 重 According to Pascal's law, the internal plate at the pressure sensor needs to move upwards at a constant velocity in a straight line, and F... 压力传感器 =0, because the pressure sensor is subjected to the pressure transmitted from the pedal, i.e., the user's weight, an upward force of magnitude m needs to be added to the pressure sensor. 人实 g, so that the actual resultant force at the pressure sensor meets the resultant force required at the pressure sensor, at which point the range hood descends in a straight line at a uniform speed.

[0091] Finally, the range hood needs to decelerate linearly until its speed reaches 0, denoted as t6. The range hood descends a total of L, according to F... 浮 -m 重 g = m 重 *v / (t6-t5) determines the forces acting on the range hood during its motion. When the range hood needs to descend in a uniformly decelerated linear motion, according to Pascal's law, the internal plate at the pressure sensor needs to ascend in a uniformly decelerated linear motion. Therefore, the net force at the pressure sensor needs to be downward. Since the pressure sensor is subjected to the pressure transmitted from the pedal, i.e., the user's weight, we obtain the pressure transmitted from the pedal, i.e., the user's weight, m. 人实 g, compared to F 压力传感器 and m 人实 g.

[0092] In F 压力传感器 ≥m 人实In case g, it means the user's gravity does not meet the net force required at the pressure sensor. Therefore, the pressure sensor is controlled to increase the number of connected small floats to increase the downward force, with a magnitude of F. 压力传感器 -m 人实 g, so that the actual resultant force at the pressure sensor meets the resultant force required at the pressure sensor, and the direction of the resultant force at the pressure sensor is downward. At this time, the range hood decelerates and descends in a straight line.

[0093] In F 压力传感器 <m 人实 In case g, it indicates that the user's gravity is too great, meaning the downward force provided by gravity is too large and does not meet the net force required at the pressure sensor. Therefore, the pressure sensor is controlled to reduce the number of connected small floats to increase the upward force, with a magnitude of m. 人实 gF 压力传感器 This partially offsets the downward force of gravity, ensuring that the actual resultant force at the pressure sensor meets the required resultant force. The direction of the resultant force at the pressure sensor is downward, causing the range hood to decelerate and descend in a straight line.

[0094] The range hood descends in a straight line with uniform deceleration until it stops. While the range hood remains stationary, the limiting plate of the control float pops out and into the limiting groove of the connector to fix the float, keeping the range hood in place. This allows for convenient and normal use of the range hood.

[0097] As can be seen from the embodiments provided in this application above, this application connects to the range hood via a floating component.
