[0044] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0045] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0046] The terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise specified, the meaning of "a plurality" is two or more.

[0047] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. Additionally, when describing pipelines or channels, the terms "connection" and "coupling" used in this application have the meaning of conducting. The specific meaning needs to be understood in combination with the context.

[0048] In the embodiments of the present application, words such as "exemplary" or "for example" are used to represent examples, illustrations, or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Exactly, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0049] As used herein, "about", "substantially", or "approximately" includes the stated value and the average value within an acceptable deviation range of the specific value, where the acceptable deviation range is determined by those of ordinary skill in the art considering the measurement being discussed and the errors associated with the measurement of the specific quantity (i.e., the limitations of the measurement system).

[0050] A range hood is a device installed above a kitchen stove to remove the oil fumes, smoke, and odors generated during cooking. It can purify the air by suction and filtration, reducing the pollution of the kitchen and the home environment by oil fumes.

[0051] The oil fume absorbed by the range hood is discharged through the exhaust port fixed on the wall. The range hood is connected to the exhaust port through an exhaust pipe. If the range hood is not fixedly installed, it may cause the exhaust pipe to be unstable, which will affect the use effect of the range hood and prevent the effective discharge of oil fume and odor.

[0052] The range hood is usually installed by fixedly connecting it to the wall. This installation method of fixed connection involves steps such as determining the installation height in advance and drilling holes in the wall. Due to measurement errors and other reasons, after hanging the range hood, the air inlet surface of the range hood may be uneven, resulting in problems such as poor smoking effect, oil leakage and dripping of the range hood, or there may be a height difference between the range hood and the cabinet, affecting the installation effect of the range hood.

[0053] If the installation level and height of the range hood are adjusted, repositioning and drilling are required, which is not only difficult but also increases the installation cost of the range hood and reduces the user experience.

[0054] To solve the above technical problems, the embodiment of the present application provides a range hood, which can be a side suction range hood, a top suction range hood, etc.

[0055] See Figure 1 , the range hood in the present application includes a main body 100. One side surface of the main body 100 is an installation surface 1011, and the installation surface 1011 is used to connect to the wall. After installing the main body 100 on the wall, it can ensure that the range hood is firmly fixed on the wall and prevent accidents.

[0056] Exemplarily, the main body 100 of the range hood in the present application includes a fan cover 101. The fan cover 101 is usually located above the range hood and is used to cover and protect the internal fan and impeller.

[0057] The main function of the fan cover 101 is to increase the wind resistance, so that the oil fume, smoke and other gases generated during cooking are more easily sucked into the range hood. At the same time, the fan cover 101 also plays a role in reducing noise and preventing external foreign objects from entering the fan mechanism.

[0058] Another exemplarily, the main body 100 of the range hood in the present application further includes a smoke collecting hood 102. The smoke collecting hood 102 is communicated with the fan cover 101. The smoke collecting hood 102 includes a smoke collecting plate, and the smoke collecting plate faces the stove.

[0059] The smoke collecting hood 102 is located above the stove, close to the cooking area, and is used to collect and guide the harmful gases such as oil fume and smoke generated during cooking into the range hood.

[0060] It should be noted that the installation surface 1011 for the range hood to be connected to the wall can be the surface of the blower housing 101 close to the wall, or the surface of the smoke collecting hood 102 close to the wall. This application does not make any limitations in this regard.

[0061] For the convenience of description, the following content will take the installation surface 1011 as the surface of the blower housing 101 close to the wall for exemplary illustration.

[0062] Furthermore, referring to Figure 1 , the range hood in this application further includes at least one connection component between the wall and the main body 100.

[0063] It should be noted that the number of connection components in this application can be one, two, or more. This application does not make any limitations in this regard.

[0064] Among them, referring to Figure 1 , the connection component includes a fixed seat 200 and a movable seat 300 that can slide relative to each other. The fixed seat 200 is used for fixed connection with the wall, and one side surface of the fixed seat 200 is fixed to the wall. The movable seat 300 is slidably connected to the fixed seat 200, and the installation surface 1011 of the main body 100 is connected to the movable seat 300.

[0065] Exemplarily, the movable seat 300 and the installation surface 1011 are connected by bolts.

[0066] Another exemplarily, referring to Figure 2 and Figure 3 , a hook 303 is provided on the surface of the movable seat 300 (not shown in the figure) facing away from the fixed seat 200, and a card hole 10111 detachably connected to the hook 303 is provided on the installation surface 1011. By matching the positions of the card hole 10111 and the hook 303, the main body 100 can be installed on the movable seat 300.

[0067] Referring to Figure 4 and Figure 5 , the connection component further includes a gear adjusting member 400 and a rack adjusting member 500 provided between the fixed seat 200 and the movable seat 300, and the rack adjusting member 500 meshes with the gear adjusting member 400. In this application, the cooperation between the rack adjusting member 500 and the gear adjusting member 400 can be utilized to achieve the sliding connection between the movable seat 300 and the fixed seat 200, thereby realizing the sliding connection between the range hood and the wall.

[0068] In this way, after the range hood is installed, if there is a problem that the installation position is inaccurate and needs to be adjusted, the user only needs to adjust the rack adjusting member 500 and the gear adjusting member 400 to adjust the position of the range hood, which is convenient to operate.

[0069] Moreover, the transmission mode between the rack adjusting member 500 and the gear adjusting member 400 can meet the adjustment of large loads, can bear a relatively large mass of objects, and maintain accurate and stable positions.

[0070] In addition, the structural design of the rack adjusting member 500 and the gear adjusting member 400 makes the position of the range hood relatively stable. Since the meshing tooth patterns of the rack adjusting member 500 and the gear adjusting member 400 fit each other, it can effectively prevent the object from shaking or being unstable during the adjustment process, improving the overall stability.

[0071] Specifically, by changing the rotation angle of the gear adjusting member 400, the moving position of the range hood can be accurately controlled. This precise adjustment method can meet the user's need for fine distance adjustment of the range hood after the range hood is installed.

[0072] Exemplarily, the gear adjusting member 400 can be rotatably connected to one of the fixed seat 200 and the moving seat 300, and the present application does not limit this. At this time, the rack adjusting member 500 is connected to the other of the fixed seat 200 and the moving seat 300.

[0073] It can be understood that when the gear adjusting member 400 is rotatably connected to the fixed seat 200, the rack adjusting member 500 is connected to the moving seat 300; when the gear adjusting member 400 is rotatably connected to the moving seat 300, the rack adjusting member 500 is connected to the fixed seat 200.

[0074] For the convenience of description, the following content takes the gear adjusting member 400 being rotatably connected to the fixed seat 200 and the rack adjusting member 500 being connected to the moving seat 300 as an example for illustration.

[0075] In some embodiments, referring to Figure 6 , in the present application, the moving seat 300 includes a connecting portion 301 and a sliding portion 302 that are fixedly connected, and the installation surface 1011 (not shown in the figure) is connected to the connecting portion 301.

[0076] In some embodiments, referring to Figure 6 and combining with Figure 7 , the fixed seat 200 includes a fixed portion 201 and a supporting portion 202 that are fixedly connected. The fixed portion 201 is located on the side of the supporting portion 202 close to the moving seat 300, and the fixed portion 201 is fixed to the wall.

[0077] Exemplarily, the fixed portion 201 is connected to the wall by bolts.

[0078] Exemplarily, the fixed portion 201 is welded to the surface of the wall.

[0079] In some embodiments, referring to Figure 7 and combining with Figure 8, the supporting part 202 is provided with a receiving cavity 2021, and the sliding part 302 can be received in the receiving cavity 2021.

[0080] Wherein, the sliding part 302 is slidably connected to the wall surface of a part of the receiving cavity 2021, and the sizes of the sliding part 302 and the receiving cavity 2021 cooperate with each other to ensure stable sliding.

[0081] Exemplarily, the shape of the sliding part 302 is a rectangular slider, and a part of the receiving cavity 2021 is a rectangular chute, or the shape of the sliding part 302 is a V-shaped slider, and a part of the receiving cavity 2021 is a V-shaped chute. The present application does not limit this.

[0082] In some embodiments, continue to refer to Figure 7 , the receiving cavity 2021 includes a limiting space 20211. The X direction shown in the figure is the direction from the fixed seat 200 to the moving seat 300. Along the direction from the fixed seat 200 to the moving seat 300, the width of the limiting space 20211 gradually decreases, and the width of the sliding part 302 gradually increases. The sliding part 302 is slidably received in the limiting space 20211 in cooperation.

[0083] In this way, refer to Figure 8 and combine with Figure 7 , the cooperation between the sliding part 302 and the wall surface of the limiting space 20211 is tight. Even if the sliding part 302 has a slight swing or deflection during the sliding process, the sliding part 302 can automatically calibrate its position.

[0084] In some embodiments, refer to Figure 7 , along the horizontal direction, that is, the X direction shown in the figure, the cross-section of the sliding part 302 is in an isosceles trapezoid shape, and the wider end of the sliding part 302 is located on the side opposite to the connecting part 301 of the narrower end.

[0085] The cross-section of the limiting space 20211 is in an isosceles trapezoid shape, and the narrower end of the limiting space 20211 is located on the side opposite to the fixing part 201 of the wider end.

[0086] It can be understood that the sliding part 302 is a trapezoidal slider at this time, and the trapezoidal slider can provide a larger contact area with the limiting space 20211 during the movement, thereby increasing the friction force and improving the stability and anti-lateral displacement ability of the sliding part 302 during the sliding process. It can better maintain the movement direction of the sliding part 302 and ensure the accuracy and stability of the movement.

[0087] In some embodiments, refer to Figure 7, the accommodation cavity 2021 further includes a gear accommodation space 20212. The gear accommodation space 20212 is located between the limit space 20211 and the fixing part 201. The gear adjusting member 400 is accommodated in the gear accommodation space 20212, and the rack adjusting member 500 is arranged on the surface of the sliding part 302 facing away from the connecting part 301.

[0088] Further, the accommodation cavity 2021 is formed by the moving seat 300 being buckled on the fixed seat 200. At this time, the accommodation cavity 2021 further includes a rack accommodation space 20213. The rack accommodation space 20213 is located between the limit space 20211 and the gear accommodation space 20212.

[0089] In this application, by arranging the gear adjusting member 400 and the rack adjusting member 500 inside the accommodation space, they can be effectively protected from the external environment, such as dust, liquid, etc. This helps to extend the service life of the gear adjusting member 400 and the rack adjusting member 500 and reduce the failure rate.

[0090] Moreover, by arranging the gear adjusting member 400 and the rack adjusting member 500 inside the accommodation space, the noise and vibration generated during the movement of the gear adjusting member 400 and the rack adjusting member 500 can also be reduced, improving the working stability of the gear adjusting member 400 and the rack adjusting member 500. At the same time, placing the gear 401 and the rack 501 inside the accommodation space can make the entire connection assembly look neater and more beautiful, avoiding the exposure of scattered parts and further beautifying the appearance of the range hood.

[0091] In some embodiments, referring to Figure 9 and Figure 10 , the gear adjusting member 400 in this application includes a gear 401, a connecting rod 402, and an adjusting knob 403 that are fixedly connected. One end of the connecting rod 402 penetrates the wall surface of the fixed seat 200 and extends into the gear accommodation space 20212. The other end of the connecting rod 402 is located outside the fixed seat 200. The end of the connecting rod 402 located in the gear accommodation space 20212 is connected to the gear 401, and the other end of the connecting rod 402 located outside the fixed seat 200 is connected to the adjusting knob 403.

[0092] In this way, referring to Figure 11 and combined with Figure 10 , by the user rotating the adjusting knob 403 of the gear adjusting member 400, the connecting rod 402 can be rotated to make the gear 401 rotate. By rotating the adjusting knob 403, the rotation direction and speed of the gear 401 can be precisely controlled, so as to achieve precise adjustment of the movement of the fixed seat 200 and the moving seat 300.

[0093] Further, for the convenience of user adjustment, a plurality of stripe columns are provided on the side wall of the adjustment knob 403, and the stripe columns are arranged around the adjustment knob 403 for one week, so as to increase the frictional force between the user and the adjustment knob 403 when the user touches the adjustment knob 403, enabling the user to easily rotate the adjustment knob 403 and enhancing the twistability of the adjustment knob 403.

[0094] Further, for the convenience of user adjustment, see Figure 12 and Figure 13 , a scale line 204 is also provided in the present application. Part of the scale line 204 is located on the fixed seat 200, and part of the scale line 204 is located on the moving seat 300. Through the scale line 204, the user can accurately control the moving position of the range hood.

[0095] In some embodiments, see Figure 9 , the rack adjusting member 500 in the present application includes a rack 501, and the rack 501 is connected to the moving seat 300.

[0096] Exemplarily, the rack 501 is welded to the surface of the moving seat 300.

[0097] Exemplarily, the rack 501 is connected to the moving seat 300 by bolts.

[0098] In some embodiments, see Figure 10 , the gear 401 in the present application is a helical gear 401, and the rack 501 is a helical rack 501.

[0099] The helical gear 401 and the helical rack 501 are matched with each other through the tooth patterns designed by the helix angle. During transmission, the force is transmitted and converted through the acting force between the inclined planes to achieve the purpose of mutual movement.

[0100] Among them, the contact area between the teeth of the helical gear 401 and the helical rack 501 is relatively large, which can bear a large load and provide a more stable transmission effect.

[0101] Therefore, by adopting the transmission method of the helical gear 401 and the helical rack 501, the gear adjusting member 400 and the rack adjusting member 500 in the present application can bear the large radial and axial loads of the range hood body 100 and meet the transmission requirements during the position adjustment of the range hood body 100.

[0102] In some embodiments, see Figure 14 , the fixed seat 200 in the present application further includes a plurality of mounting holes 203 arranged at intervals, and the first pressing member 600 is arranged in the mounting holes 203. Through the plurality of mounting holes 203 arranged at intervals, the first pressing member 600 can be fixed at different positions.

[0103] In some embodiments, see Figure 15, a first elastic notch 2022 recessed toward the fixing portion 201 is provided on the surface of the supporting portion 202 facing away from the fixing portion 201. The portion of the supporting portion 202 between the first elastic notch 2022 and the limiting space 20211 is the first supporting portion 2023, and the portion of the supporting portion 202 facing away from the limiting space 20211 of the first elastic notch 2022 is the second supporting portion 2024.

[0104] The connecting component in the present application further includes a first pressing member 600. When the range hood does not need to be fixed, driving the first pressing member 600 to move can limit the movement of the moving seat 300, thereby limiting the movement of the main body 100 of the range hood. The operation is simple and convenient for users to use.

[0105] Further, the first pressing member 600 is disposed through the second supporting portion 2024 and is movable relative to the first supporting portion 2023 in a direction close to the limiting space 20211. The first pressing member 600 includes a first pressing portion 602, and the first pressing portion 602 is received in the first elastic notch 2022.

[0106] Specifically, one end of the first pressing member 600 penetrates through the second supporting portion 2024. When the user moves the main body 100 to a position that meets the requirements, the user presses the first pressing member 600 in the direction of the limiting space 20211, which can make the first pressing portion 602 of the first pressing member 600 abut against the second supporting portion 2024. Continuing to press the first pressing member 600 can make the second supporting portion 2024 abut against the wall surface of the sliding portion 302 until they cannot slide relative to each other.

[0107] Wherein, by providing the first elastic notch 2022, when the second supporting portion 2024 is impacted by the first pressing member 600, it can play a certain buffering role, thereby reducing the damage to the second supporting portion 2024 caused by the impact force and prolonging the service life of the second supporting portion 2024.

[0108] In addition, the first elastic notch 2022 provides a telescopic stroke for the first pressing member 600 to meet the requirements of locking and releasing the sliding portion 302 by the first pressing member 600.

[0109] Further, in order to enhance the limiting ability of the connecting component to the sliding portion 302, the connecting component in the present application further includes a second pressing member 700, and the first pressing member 600 and the second pressing member 700 are oppositely arranged.

[0110] In some embodiments, refer to Figure 15, on the surface of the support part 202 facing away from the fixing part 201, there is a second elastic notch 2027 recessed towards the fixing part 201. The second elastic notch 2027 is located on the side of the limiting space 20211 away from the first elastic notch 2022. The part of the support part 202 between the first elastic notch 2022 and the limiting space 20211 is the third support part 2025, and the part of the support part 202 on the side of the first elastic notch 2022 facing away from the limiting space 20211 is the fourth support part 2026;

[0111] The second pressing member 700 is inserted through the fourth support part 2026 and is movable relative to the fourth support part 2026 in the direction close to the limiting space 20211. The second pressing member 700 includes a second pressing part 702, and the second pressing part 702 is received in the second elastic notch 2027.

[0112] In this way, by driving the first pressing member 600 and the second pressing member 700 to move, pressure can be applied to the sliding part 302 from both sides, so as to achieve uniform fixing of the sliding part 302, and avoid the situation that the sliding part 302 is deformed or damaged due to excessive unilateral force.

[0113] At the same time, applying pressure to both sides of the sliding part 302 can balance the force on the sliding part 302, improve the stability and reliability of the sliding part 302 in the static state, so as to ensure that the moving seat 300 will not loosen or fall off during the static process, and further improve the safety of the range hood during use.

[0114] In some embodiments, referring to Figure 15 , the second support part 2024 is provided with a first threaded hole 20241. The first pressing member 600 includes a first stud part 603. The first stud part 603 is received in the first threaded hole 20241, and the first stud part 603 is in threaded cooperation with the first threaded hole 20241.

[0115] Furthermore, referring to Figure 15 , the fourth support part 2026 is provided with a second threaded hole 20261. The second pressing member 700 includes a second stud part 703. The second stud part 703 is received in the second threaded hole 20261, and the second stud part 703 is in threaded cooperation with the second threaded hole 20261.

[0116] With the above settings, when installing the first pressing member 600 and the second pressing member 700, the user screws the first stud part 603 into the first threaded hole 20241 and screws the second stud part 703 into the second threaded hole 20261, then the driving of the first pressing member 600 and the second pressing member 700 can be realized. The structure is simple and convenient to operate.

[0117] In this way, by screwing the first stud portion 603 into the first threaded hole 20241 and the second stud portion 703 into the second threaded hole 20261, the positions and depths of the first pressing member 600 and the second pressing member 700 can be flexibly adjusted as needed to meet different user requirements.

[0118] In some embodiments, referring to Figure 15 , the first pressing member 600 includes a first handle 601. The first handle 601 is connected to one end of the first stud portion 603 facing away from the first pressing portion 602, and the handle is located on the side of the second support portion 2024 facing away from the first elastic notch 2022.

[0119] Furthermore, the first pressing member 600 includes a second handle 701. The second handle 701 is connected to one end of the second stud portion 703 facing away from the second pressing portion 702, and the second handle 701 is located on the side of the second support portion 2024 facing away from the second elastic notch 2027.

[0120] With the above settings, the user only needs to rotate the first handle 601 and the second handle 701 to drive the first pressing member 600 and the second pressing member 700. Setting the first handle 601 and the second handle 701 allows the user to grip the first pressing member 600 and the second pressing member 700 more stably during rotation, avoiding the risk of hand slipping or injury due to careless operation and improving the safety of the operation.

[0121] At the same time, by setting the first handle 601 and the second handle 701, the operating force arm of the user can be increased, enabling the user to more easily apply force to rotate the first handle 601 and the second handle 701, reducing the labor intensity.
