[0028] The utility model provides the following description with reference to the accompanying drawings to help fully understand the various embodiments of the utility model as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the utility model.

[0029] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply 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 understood as a limitation on the present invention.

[0030] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0031] The embodiment of the utility model provides a range hood with a bottom plate that can be disassembled and assembled by hand, such as Figure 1-4As shown, the housing 100 includes a bottom housing component located at the bottom thereof, the bottom housing component is provided with an opening 101, and the bottom housing 200 is provided with a smoke inlet 201 penetrating through the bottom housing component, so that oil smoke can enter the housing 100 through the smoke inlet 201. When the bottom housing 200 is mounted on the bottom housing component, the bottom housing 200 covers the opening 101. The bottom housing component may include a plate or may be composed of a plurality of plates, the opening 101 may penetrate a plate included in the bottom housing component, or may be enclosed by a plurality of plates to form the opening 101. For the convenience of explanation, the parts of the bottom housing component on both sides of the length direction, the width direction or the other directions of the opening 101 may be the first bottom housing component 110 and the second bottom housing component 120, respectively.

[0032] One end of the bottom plate 200 passes through the opening 101 and is placed on the second bottom shell assembly 120, and the second bottom shell assembly 120 supports this end of the bottom plate 200; the other end of the bottom plate 200 is provided with a plurality of through holes, and a screw member 300 that can rotate relative to the bottom plate 200 is inserted into the through holes. The screw member 300 is rotatably connected with the bottom plate 200, and the screw member 300 includes a knob portion 310 that can be screwed by the user and a buckle plate 320 connected to the top of the knob portion 310. The user can manually operate the knob portion 310 to drive the entire screw member 300 to rotate. The screw member 300 extends into the opening 101, and when the screw member 300 rotates, the buckle plate 320 will also rotate accordingly, and the buckle plate 320 can be rotated until it is hung on the first bottom shell assembly 110 or removed from the first bottom shell assembly 110.

[0033] When the buckle plate 320 is hung on the first bottom shell assembly 110, the first bottom shell assembly 110 and the second bottom shell assembly 110 respectively support the bottom plate 200 from both ends of the bottom plate 200, so that the bottom plate 200 is installed on the bottom shell assembly. When the buckle plate 320 is rotated to be removed from the first bottom shell assembly 110, the buckle plate 320 is no longer hung on the first bottom shell assembly 110, and the end of the bottom plate 200 with the perforation can be separated from the bottom shell assembly, and then the other end of the bottom plate 200 (the end placed on the second bottom shell assembly 120) is pulled out from the opening 101, thereby completing the removal of the bottom plate 200. Since the user can rotate the entire screw button 300 by twisting the knob part 310, there is no need to use other tools such as screwdrivers, and the installation and removal process can be done without the help of tools. The user can complete the installation and removal of the bottom plate 200 with bare hands, which is more convenient to operate.

[0034] In some embodiments, considering that the pinch plate 320 is only hung on the bottom shell assembly, there may be instability issues. Figure 4 and Figure 6As shown, in this embodiment, a protrusion 321 is provided on the bottom surface of the buckle plate 320, and a positioning hole 111 matched with the protrusion 321 is provided on the first bottom shell component 110. When the buckle plate 320 is rotated to be hung on the first bottom shell component 110, the protrusion 321 is inserted into the positioning hole 111. The cooperation between the protrusion 321 and the positioning hole 111 limits the buckle plate 320, restricting the buckle plate 320 from moving on the surface of the first bottom shell component 110. The buckle plate 320 is not easily removed from the first bottom shell component 110, and the bottom plate 200 can be stably installed on the bottom shell component. When it is necessary to remove the buckle plate 320 from the first bottom shell assembly 110, a certain external force is required to rotate the screw fastener, and the material deformation and / or assembly gap are used to move the protrusion 321 out of the positioning hole 111. The buckle plate 320 can be removed from the first bottom shell assembly 110, the screw fastener can be detached from the first bottom shell assembly 110, and the bottom plate 200 can be removed from the bottom shell assembly.

[0035] In some embodiments, Figure 4 and Figure 6 As shown, the top surface of the gusset plate 320 is provided with a plurality of protruding reinforcing plates 322. Since the gusset plate 320 is hung on the first bottom shell assembly 110, it needs to bear the weight of the bottom plate 200 and the weight of other objects connected to the bottom plate 200. The reinforcing plates 322 can strengthen the structural strength of the gusset plate 320, so that the gusset plate 320 is not easy to break, thereby extending its service life and ensuring that the bottom plate 200 can be stably installed on the bottom shell assembly.

[0036] In this embodiment, the reinforcing plate 322 may be integrally connected to the pinch plate 320 and perpendicular to the pinch plate 320 . A plurality of reinforcing plates 322 may be provided to enhance the reinforcing effect on the pinch plate 320 .

[0037] In some embodiments, Figure 4 and Figure 5 As shown, the knob portion 310 and the clasp plate 320 are detachably connected, and the knob portion 310 and the clasp plate 320 are respectively located below and above the bottom plate 200. During installation, the knob portion 310 and the clasp plate 320 are respectively placed below and above the bottom plate 200 and aligned with the through holes on the bottom plate 200, and then the knob portion 310 and the clasp plate 320 are connected together to complete the installation of the turnbuckle. This combined structure can facilitate the assembly of the entire turnbuckle.

[0038] In this embodiment, the size of the knob portion 310 and the buckle plate 320 can be larger than the size of the through hole, so that the knob portion 310 and the buckle plate 320 cannot pass through the through hole, and the screw member cannot be separated from the bottom plate 200. At the same time, the knob portion 310 and the buckle plate 320 can be rotated relative to the bottom plate 200 to achieve a rotational connection between the screw member and the bottom plate 200. The knob portion 310 and the buckle plate 320 can be fixed with screws, snap-fit ​​connection or other methods to achieve a detachable connection with each other.

[0039] In some embodiments, Figure 4 and Figure 5 As shown, the knob portion 310 includes a disk 311 and a convex plate 312 disposed on the bottom surface of the disk 311. The thumb and index finger of the user can grasp the convex plate 312 from both sides of the convex plate 312, and then rotate the convex plate 312 to drive the entire turnbuckle to rotate. The knob portion 310 of this structure is easy to grasp and more labor-saving to operate.

[0040] In some embodiments, Figure 1 and Figure 6 As shown, the bottom plate 200 is provided with a perforated end and a through mounting hole, and the first bottom shell component 110 is provided with a threaded hole 112 which is opposite to the mounting hole, and a hand screw 400 is passed through the mounting hole, and the hand screw 400 is fixed in the threaded hole. The bottom plate 200 is still unstable when it is hung on the bottom shell component. In this embodiment, the bottom plate 200 is further reinforced by the hand screw 400, so that the bottom plate 200 can be stably installed on the bottom shell component. The hand screw 400 does not require the user to use tools such as a screwdriver, and can be manually screwed, which still ensures that the user can disassemble and install the bottom plate 200 by hand.

[0041] In some embodiments, the range hood with a bottom plate that can be manually disassembled further comprises a controller, which can control the entire range hood to start or stop working. Figure 2 and Figure 6 As shown, a sensor 500 is fixed at the opening 101, and the sensor 500 is connected to the controller, and the sensor 500 is used to detect whether the bottom plate 200 is installed on the bottom shell assembly. When the sensor 500 detects that the bottom plate 200 is not installed on the bottom shell assembly, it means that the bottom plate 200 has been removed from the bottom shell assembly. The controller is used to control the range hood to stop working, to ensure that the fan and other components in the housing 100 will not be started by mistake, and the user is not prone to danger when cleaning the inside of the housing 100, thereby improving the safety of use.

[0042] Furthermore, the sensor device 500 includes a micro switch. When the base plate 200 is installed on the bottom shell assembly, the base plate 200 triggers the micro switch, and the sensor device 500 detects that the base plate 200 is installed on the bottom shell assembly; when the base plate 200 is removed from the bottom shell assembly, the micro switch is not triggered, and the sensor device 500 does not detect that the base plate 200 is installed on the bottom shell assembly.

[0043] The embodiment of the utility model also provides another range hood whose bottom plate can be disassembled and assembled by hand. Compared with the above embodiment, the installation method of the bottom plate is different. Specifically, a plurality of through holes are provided at both ends of the bottom plate, and a screw member that can rotate relative to the bottom plate is provided in the through holes. The screw member is rotatably connected to the bottom plate. The screw member includes a knob portion that can be screwed by the user and a buckle plate connected to the top of the knob portion. The user can manually operate the knob portion to drive the entire screw member to rotate. The screw members at both ends of the bottom plate extend into the opening. When the screw member close to the first bottom shell assembly rotates, the buckle plate will also rotate accordingly. The buckle plate can be rotated until it is hung on the first bottom shell assembly or removed from the first bottom shell assembly; when the screw member close to the second bottom shell assembly rotates, the buckle plate will also rotate accordingly. The buckle plate can be rotated until it is hung on the second bottom shell assembly or removed from the second bottom shell assembly.

[0044] Therefore, in this embodiment, screw fasteners are provided at both ends of the bottom plate, and the screw fasteners at both ends of the bottom plate can be hung on the bottom shell assembly. When installing and removing the bottom plate, it is only necessary to rotate the screw fasteners at both ends of the bottom plate.

[0045] Furthermore, when the bottom surface of the buckle plate is provided with a protrusion, the first bottom shell assembly and the second bottom shell assembly are both provided with positioning holes adapted to the protrusion, and the protrusions on the screw fasteners at both ends of the bottom plate can be respectively inserted into the positioning holes on the first bottom shell assembly and the second bottom shell assembly to limit the buckle plate close to the first bottom shell assembly from moving on the surface of the first bottom shell assembly, and to limit the buckle plate close to the second bottom shell assembly from moving on the surface of the second bottom shell assembly, so that the bottom plate can be stably installed on the bottom shell assembly.

[0046] Furthermore, when mounting holes are provided at both ends of the bottom plate, the first bottom shell assembly and the second bottom shell assembly are respectively provided with threaded holes corresponding to the mounting holes at both ends of the bottom plate, and hand screws are passed through the mounting holes, and the hand screws are fixed in the threaded holes. The connection between the bottom plate and the first bottom shell assembly and the connection between the bottom plate and the second bottom shell assembly are further reinforced by the hand screws, so that the bottom plate can be stably installed on the bottom shell assembly. The hand screws do not require the user to use tools such as screwdrivers, and can be manually screwed, which still ensures that the user can remove and install the bottom plate by hand.

[0047] The terms and words used in the above description and claims are not limited to the literal meanings, but are only used by the applicant to enable a clear and consistent understanding of the utility model. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the utility model is provided only for illustration, and not for limiting the utility model as defined by the attached claims and their equivalents.
