When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0038] This application proposes a desktop range hood, combined with Figure 1 and Figure 2 As shown, in some embodiments, the desktop range hood includes a range hood body 1000, a body 2000 and a base 3000, the range hood body 1000 is connected to the body 2000, the body 2000 is connected to the base 3000, the base 3000 supports the body 2000 and the body 2000 supports the range hood body 1000 (that is, the base 3000 supports the body 2000 and the range hood body 1000), when the desktop range hood is placed on a supporting surface, the base 3000 is used to support the supporting surface, that is, the base 3000 is in contact with the supporting surface to support the entire desktop range hood, and the projection along the top-down direction is designed to have a smaller area than the projection 3001 of the base 3000, and the body 2000 is arranged to be tapered along the bottom-up direction.

[0039] When the desktop range hood is placed on a supporting surface, the base 3000 contacts the supporting surface and is supported on the supporting surface, thereby placing the desktop range hood on the supporting surface. The projection 3001 area of ​​the base 3000 is designed to be larger than the projection 2001 area of ​​the body 2000, thereby increasing the contact area with the supporting surface and improving the placement stability of the desktop range hood. The body 2000 is designed to taper from bottom to top, which helps to lower the center of gravity of the body 2000 and thus lower the center of gravity of the desktop range hood, thereby further improving the placement stability of the desktop range hood.

[0040] Specifically, the range hood body 1000 is used to extract oil smoke, for example, the range hood body 1000 includes an air duct housing 1100, a bracket 1200, a fan 1300, a filter component 1400 and a protective cover 1500. The air duct housing 1100 is provided with an air duct 1110, and the air duct housing 1100 can be integrally formed or formed by connecting at least two parts, one end of the air duct 1110 constitutes an air inlet 1111, and the other end of the air duct 1110 constitutes an air outlet 1112. The bracket 1200 needs to be connected and fixed with the air duct shell 1100 and set in the air duct 1110. There are many ways to connect the bracket 1200 and the air duct shell 1100, such as welding, screw connection, clamping, etc. It can be understood that the bracket 1200 is a component used to support other components. The bracket 1200 can be made of metal materials or other materials. The bracket 1200 can be a regular shape or an irregular shape. In this embodiment, the bracket 1200 is a sheet metal part. The so-called sheet metal part is that the bracket 1200 is processed by a sheet metal process. The fan 1300 is connected to the bracket 1200 and fixed in the air duct 1110. At this time, the fan 1300 is between the air inlet 1111 and the air outlet 1112. The fan 1300 drives the oil smoke from the air inlet 1111 into the air duct 1110 and discharges the air duct 1110 from the air outlet 1112. The filter component 1400 is installed on the air duct housing 1100 and is located in the air duct 1110. The filter component 1400 is located upstream of the fan 1300 (such as at the air inlet 1111). The oil smoke first flows through the filter component 1400 and then flows through the fan 1300. By setting the filter component 1400, the filter component 1400 can filter the oil smoke to obtain oil liquid. The protective cover 1500 is located downstream of the fan 1300 (such as at the air outlet 1112), and the protective cover 1500 can protect the internal structure.

[0041] The fuselage 2000 is used to support the range hood body 1000. For example, the range hood body 1000 is connected to and installed on the fuselage 2000 and is located above the fuselage 2000. When the desktop range hood is placed on the supporting surface, the weight of the range hood body 1000 is applied to the fuselage 2000. The fuselage 2000 includes an electronic control component, a guide member and an oil cup 2200. The electronic control component controls the operation of the desktop range hood. The guide member discharges the oil discharged from the range hood body 1000 into the oil cup 2200 for temporary storage. The oil cup 2200 is designed to be detachable, that is, the oil cup 2200 can be installed at a predetermined position or can be disassembled. In this way, the user can remove the oil cup 2200 and pour out the oil and clean the oil cup 2200, and the cleaned oil cup 2200 can be reinstalled at a predetermined position.

[0042] The base 3000 is used to support the body 2000. For example, the body 2000 is connected to and mounted on the base 3000 and is located above the base 3000. When the tabletop range hood is placed on a support surface, the base 3000 contacts the support surface and is supported on the support surface. The weight of the range hood body 1000 and the body 2000 is applied to the base 3000. It can be understood that the support surface is a structure for placing the tabletop range hood, such as a tabletop, the ground, or a chair surface.

[0043] The orientation in this article is based on the situation that the desktop range hood is placed on the support surface and the user faces the air inlet 1111. The side of the desktop range hood facing the user is the front, the side away from the user is the back, the side corresponding to the user's left hand is the left, the side corresponding to the user's right hand is the right, the side close to the support surface is the bottom, and the side away from the support surface is the top. Projecting along the top-down direction, the area of ​​the projection 2001 of the body 2000 is designed to be smaller than the area of ​​the projection 3001 of the base 3000. That is to say, if the body 2000 is supported on the support surface, the contact area between the body 2000 and the support surface is smaller than the contact area between the base 3000 and the support surface. Compared with the body 2000 being supported on the support surface, the base 3000 being supported on the support surface can increase the contact area with the support surface, thereby facilitating the placement stability of the desktop range hood. It can be understood that when the desktop range hood is placed on the support surface, the base 3000 is located at the bottom. Even if the base 3000 is made larger, the space occupied by the user can be reduced as much as possible.

[0044] In addition, based on the design that the area of ​​the projection 2001 of the body 2000 is smaller than the area of ​​the projection 3001 of the base 3000, the body 2000 is also designed to be gradually reduced along the bottom-up direction, that is, a horizontal plane is defined, and the cross-section formed by the intersection of the horizontal plane and the body 2000 gradually becomes smaller along the bottom-up direction. On the whole, the body 2000 is approximately cone-shaped. Through such a setting, it is beneficial for the body 2000 to lower its center of gravity, and then lower the center of gravity of the desktop range hood, thereby further improving the placement stability of the desktop range hood, and the desktop range hood is less likely to tip over when touched by a user.

[0045] Combination Figure 1 and Figure 5 As shown, in some embodiments, the projection 2001 of the body 2000 (referring to the projection along the top-down direction) is designed to be located within the range of the projection 3001 of the base 3000 (referring to the projection along the top-down direction). In this way, when observed from the top-down direction, the center of gravity of the body 2000 is located within the range of the projection 3001 of the base 3000, which is beneficial to further improve the placement stability of the desktop range hood.

[0046] Continue to combine Figure 1 and Figure 5 As shown, in some embodiments, the contour of the projection 2001 of the body 2000 (referring to the projection along the top-down direction) is designed to be alternately arranged with the contour of the projection 3001 of the base 3000 (referring to the projection along the top-down direction). In this way, when observed along the top-down direction, the center of gravity of the body 2000 is closer to the center of the projection 3001 of the base 3000, which is beneficial to further improve the placement stability of the desktop range hood.

[0047] Similar to the relative positional relationship between the projection 2001 of the body 2000 and the projection 3001 of the base 3000, when projecting in a top-down direction, the projection of the top of the body 2000 can also be located within the range of the projection of the bottom of the body 2000, and the outline of the projection of the top of the body 2000 and the outline of the projection of the bottom of the body 2000 are alternately arranged, which can also enhance the placement stability of the desktop range hood.

[0048] Combination Figure 3 and Figure 4 As shown, in some embodiments, the base 3000 includes a base body 3100 and a cover 3200. The base 3000 is suitable for being supported on a supporting surface through the base body 3100. The body 2000 is connected to the base body 3100. More specifically, the body 2000 and the base body 3100 are connected and fixed via a connecting structure, and the cover 3200 covers the connecting structure.

[0049] Specifically, the support of the base 3000 to the fuselage 2000 and the range hood body 1000 is mainly achieved through the base body 3100. That is, when the desktop range hood is placed on a supporting surface, the base body 3100 needs to be in contact with the supporting surface. Therefore, it is necessary to ensure that the base body 3100 has a high structural strength. The base body 3100 can be made of metal material, plastic material or other materials. For example, the base body 3100 is manufactured by one-piece injection molding to ensure structural strength.

[0050] The fuselage 2000 and the base body 3100 are connected and fixed by a connecting structure. In this embodiment, the cover 3200 is designed, and the cover 3200 can cover the connecting structure and avoid the exposure of the connecting structure. It can be understood that since the base body 3100 needs to support the fuselage 2000 and the range hood body 1000, the connecting structure needs to ensure the effective fixation between the fuselage 2000 and the base body 3100. Therefore, the design of the connecting structure can be mainly based on the firmness and convenience of the connection, and the aesthetics is achieved through the cover 3200, thereby avoiding the exposure of the connecting structure.

[0051] Combination Figures 6 to 9 As shown, in some embodiments, the desktop range hood also includes a threaded fastener (not shown in the figure), the base body 3100 is provided with a first fastening hole 3110, and the body 2000 is provided with a second fastening hole 2100. The threaded fastener, the second fastening hole 2100 and the first fastening hole 3110 constitute the connection structure mentioned above. When connecting the body 2000 and the base body 3100, the threaded fastener passes through the first fastening hole 3110 and the second fastening hole 2100 in sequence and is screwed.

[0052] Specifically, the threaded fastener has an external thread, for example, the threaded fastener is a screw, and the threaded fastener passes through the first fastening hole 3110 and the second fastening hole 2100 to achieve threaded connection, thereby achieving the connection and fixation between the fuselage 2000 and the base body 3100. The threaded connection method simplifies the design and is easy to operate, and the fastening force is controllable, ensuring the connection and fixation effect between the fuselage 2000 and the base body 3100.

[0053] For example, the first fastening hole 3110 is a through hole, the second fastening hole 2100 is a blind hole, and the hole wall of the second fastening hole 2100 has an internal thread. When the base body 3100 is assembled to the bottom of the fuselage 2000, a threaded fastener is sequentially passed through the first fastening hole 3110 and the second fastening hole 2100, and the threaded fastener is screwed with the second fastening hole 2100, thereby achieving the connection and fixation between the fuselage 2000 and the base body 3100. Since the threaded fastener, the first fastening hole 3110 and the second fastening hole 2100 constitute a connection structure, the cover 3200 covers the threaded fastener, the first fastening hole 3110 and the second fastening hole 2100 after being installed on the base body 3100, so as to prevent the threaded fastener, the first fastening hole 3110 and the second fastening hole 2100 from being exposed.

[0054] Furthermore, combined with Figure 3 and Figure 4 As shown, in some embodiments, the base body 3100 is provided with an annular positioning rib 3120, the lower end of the fuselage 2000 is covered with the annular positioning rib 3120, and the lower end of the fuselage 2000 is abutted against the annular positioning rib 3120, thereby forming an assembly positioning, which makes it more convenient for the threaded fastener to cooperate with the first fastening hole 3110 and the second fastening hole 2100.

[0055] Specifically, the annular positioning rib 3120 is arranged on the side of the base body 3100 facing the fuselage 2000. When assembling the fuselage 2000 and the base body 3100, the fuselage 2000 and the base body 3100 are controlled to move toward each other until the lower end of the fuselage 2000 touches the base body 3100. At this time, the lower end of the fuselage 2000 is covered with the annular positioning rib 3120 and abuts against the annular positioning rib 3120, thereby realizing the positioning cooperation between the fuselage 2000 and the base body 3100, and the relative position change between the fuselage 2000 and the base body 3100 is not easy to occur. In particular, the annular positioning rib 3120 is designed as a non-centrally symmetrical pattern, which has an anti-foolproof effect, so that the first fastening hole 3110 is aligned with the second fastening hole 2100, which makes it more convenient for the threaded fastener to pass through the first fastening hole 3110 and the second fastening hole 2100 to achieve a fastened connection.

[0056] In some embodiments, the cover 3200 is designed to be snap-fitted, bonded, interference-fitted, or magnetically connected to the base body 3100 , thereby being fixed to the base body 3100 .

[0057] Specifically, the main function of the cover 3200 is to cover the connection structure between the fuselage 2000 and the base body 3100. In this embodiment, the cover 3200 can be fixed to the base body 3100 by snap connection, bonding, interference fit, or magnetic connection, thereby covering the connection structure between the fuselage 2000 and the base body 3100.

[0058] For example, the cover 3200 is connected and fixed to the base body 3100 by bonding, and an adhesive is provided on the side of the cover 3200 facing the base body 3100. When the cover 3200 is bonded to the base body 3100, the adhesive is located between the cover 3200 and the base body 3100. Through such a setting, the cover 3200 can be fixed to the base body 3100 and the cover 3200 covers the connecting structure.

[0059] For example, the cover 3200 is connected and fixed to the base body 3100 by interference fit. The base body 3100 has a cavity 3130. The threaded fastener passes through the first fastening hole 3110 and the second fastening hole 2100 in sequence from one side of the cavity 3130 to fix the base body 3200 to the fuselage 200. Then, the cover 3200 is embedded in the cavity 3130 and the cover 3200 is interference fit with the cavity 3130. Through such a setting, the cover 3200 can be fixed to the base body 3100 and the cover 3200 covers the connecting structure.

[0060] For example, the cover 3200 is connected and fixed to the base body 3100 by means of a magnetic connection. A magnetic portion is provided on the side of the cover 3200 facing the base body 3100 or inside the cover 3200. A magnetic portion is also provided on the side of the base body 3100 facing the cover 3200 or inside the base body 3100. When the cover 3200 and the base body 3100 are assembled, they are connected by means of a magnetic connection, and the cover 3200 can cover both the connection structure and the magnetic portion.

[0061] Combination Fig. 9 As shown, in some embodiments, the cover 3200 is snap-connected to the base body 3100, which is convenient and quick. A claw 3210 is provided on the side of the cover 3200 facing the base body 3100, and the base body 3100 is provided with a hole 3140. When assembling the cover 3200 and the base body 3100, the cover 3200 and the base body 3100 move toward each other until the claw 3210 is snapped into the hole 3140, thereby fixing the cover 3200 to the base body 3100, and the cover 3200 can cover the connecting structure as well as the claw 3210 and the hole 3140.

[0062] Furthermore, combined with Fig. 9 As shown, in some embodiments, the cover 3200 is provided with a raised portion 3220 , which is raised toward the base body 3100 , and the base body 3100 is provided with a positioning hole 3150 , and the raised portion 3220 is used to be inserted into the positioning hole 3150 .

[0063] Specifically, when assembling the cover 3200 and the base body 3100, the cover 3200 and the base body 3100 are controlled to move toward each other so that the protrusion 3220 is inserted into the positioning hole 3150, thereby forming an assembly positioning. The relative position of the cover 3200 and the base body 3100 is not easy to change. Since the cover 3200 and the base body 3100 are connected by the claw 3210 and the hole 3140, the cooperation between the protrusion 3220 and the positioning hole 3150 can also avoid excessive force on the claw 3210 and cause the claw 3210 to break.

[0064] Combination Fig.10 As shown, in some embodiments, the base body 3100 is provided with a cavity 3130 open downward, the cover 3200 is embedded in the cavity 3130 and connected to the base body 3100, and the bottom surface 3230 of the cover 3200 is designed to be higher than or flush with the bottom surface 3160 of the base body 3100.

[0065] Specifically, when assembling the desktop range hood, the connection and fixation between the body 2000 and the base body 3100 is performed before the connection and fixation between the base body 3100 and the cover 3200. The threaded fastener passes through the first fastening hole 3110 and the second fastening hole 2100 from one side of the cavity 3130 in sequence to achieve the connection and fixation between the body 2000 and the base body 3100. The cover 3200 is then embedded in the cavity 3130 and connected and fixed to the base body 3100 by snap connection, bonding, interference fit or magnetic connection. The connection strength between the main body 3100 and the fuselage 2000 is greater than the connection strength between the base body 3100 and the cover 3200. Therefore, the bottom surface 3230 of the cover 3200 is designed to be flush with the bottom surface 3160 of the base body 3100, or the bottom surface 3230 of the cover 3200 is higher than the bottom surface 3160 of the base body 3100. In this way, when the desktop range hood is placed on a supporting surface, the contact between the base body 3100 and the supporting surface is ensured to avoid shaking of the desktop range hood due to the contact between the cover 3200 and the supporting surface alone.

[0066] When the cover 3200 is embedded in the concave cavity 3130, there is a mounting gap 3300 between the cover 3200 and the base body 3100. In order to avoid the exposure of the mounting gap 3300, the cover 3200 is provided with a mounting gap 3300.
