Description

Technical Field

[0001] This utility model relates to the field of range hood technology, specifically to an oil cup mounting structure and a range hood. Background Technology

[0002] A range hood is a kitchen appliance that purifies the kitchen environment. It quickly removes cooking fumes and waste from the stove and exhausts them outdoors, reducing pollution and purifying the air. To facilitate the removal and installation of the grease cup, it often features a detachable structure. Current disassembly mechanisms require the user to manually engage a locking mechanism with the grease cup to install it onto the locking mechanism.

[0003] Chinese patent application number 202222907702.0, published on April 14, 2023, discloses an oil cup mounting structure for a range hood, including a housing, an oil cup, a locking member, and an elastic member. The second engaging portion of the locking member extends downward from the crossbar portion and includes an extension post and a hook from top to bottom. The hook includes an engaging surface extending outward from the side wall of the extension post in a left-right direction, serving as a mating surface with the first engaging portion of the oil cup, and a guide surface extending downward at an angle from the outer periphery of the engaging surface, thus forming a pointed shape. The elastic member is configured to act on the locking member, keeping the hook of the locking member always extending outward, and storing energy when the hook of the locking member retracts under external force. This oil cup mounting structure, with the hook having a guide surface engaging with the oil cup, eliminates the need for manual operation of the locking member engaging with the oil cup during installation.

[0004] The oil cup installation of this structure requires inserting a hook into the third opening to achieve contact between the hook and the wall of the third opening. Therefore, during installation, the position of the hook and the third opening must be adjusted before they can be aligned. However, there is no guiding or limiting structure between the third opening and the hook, so alignment can only be achieved by observing the position of the third opening and the hook. The oil cup installation is complicated and cannot be done blindly. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide an oil cup installation structure and a range hood, wherein the guide channel guides the movement of the oil cup, and there is no need to adjust the position of the spring mounting pin and the mounting hole when installing the oil cup, so as to realize blind operation of oil cup installation and make oil cup installation simple.

[0006] To solve the above-mentioned technical problems, the technical solution used in this utility model is as follows:

[0007] The present invention relates to an oil cup mounting structure and a range hood, comprising an oil cup and a hanging ear assembly. The hanging ear assembly is provided with a spring-loaded mounting pin, and the oil cup is provided with a mounting hole. The oil cup is detachably mounted on the spring-loaded mounting pin through the mounting hole. A guide portion is provided on the oil cup, located above the mounting hole. The guide portion is bent outward from the end of the oil cup. The guide portion is provided with a guide channel for compressing the spring-loaded mounting pin and guiding the movement of the mounting hole to cooperate with the spring-loaded mounting pin.

[0008] Preferably, the guide portion includes a first blocking surface, a second blocking surface, and a guide surface; the guide surface is disposed between the first blocking surface and the second blocking surface, and the bending amplitude of the guide surface is greater than the bending amplitude of the first blocking surface and the second blocking surface; a guide channel is formed between the first blocking surface, the guide surface, and the second blocking surface.

[0009] Preferably, the ear-hanging assembly includes two ear-hanging covers, which are stacked and detachably connected, and the elastic mounting pin is disposed between the two ear-hanging covers; a positioning structure is provided between the two ear-hanging covers for connecting and positioning the two ear-hanging covers.

[0010] Preferably, the positioning structure includes a first limiting structure, which is used for longitudinal positioning of the two ear cover plates.

[0011] Preferably, the positioning structure includes a second limiting structure, which is used for the lateral positioning of the two ear covers.

[0012] Preferably, the first positioning structure includes a first positioning flange and a first positioning recess, the first positioning flange being disposed on one ear cover plate; the first positioning recess being disposed on another ear cover plate; and the first positioning flange being disposed in the first positioning recess.

[0013] Preferably, the second positioning structure includes a second positioning flange and a second positioning recess, the second positioning flange being disposed on one ear cover plate; the second positioning recess being disposed on another ear cover plate; and the second positioning flange being disposed in the second positioning recess.

[0014] Another objective of this utility model is to provide a range hood, including a range hood body and a detachable hanging ear assembly mounted on the range hood body.

[0015] Preferably, a shielding part is provided on one side of the hanging ear assembly, the shielding part is connected to the main body of the range hood and extends along the height of the oil cup; the height of the shielding part is greater than the height of the oil cup.

[0016] The advantages of the oil cup installation structure described in this utility model compared to existing technologies are mainly reflected in the following aspects: The guide channel guides the installation hole to engage with the elastic installation pin, guiding the movement of the oil cup. This allows the installation hole to move along the guide direction, achieving the most accurate alignment with the elastic installation pin. Thus, there is no need to adjust the position of the elastic installation pin and the installation hole during oil cup installation, enabling blind operation and simplifying the installation process. Simultaneously, the guide part is bent outwards, so that when guiding the oil cup's movement, the elastic installation pin contacts the wall surface of the guide part, compressing the elastic installation pin. Once the installation hole and the elastic installation pin are aligned, the elastic installation pin returns to its original position and extends into the installation hole, achieving connection between the installation hole and the elastic installation pin. The guide part enables rapid installation between the oil cup and the elastic installation pin.

[0017] In the guide section, the guide surface abuts against the elastic mounting pin, compressing the elastic mounting pin; the first and second blocking surfaces respectively cooperate with the elastic mounting pin to restrict the movement of the oil cup along the width direction; thus, when installing the oil cup, the oil cup can only move along the guide direction of the guide channel, facilitating the cooperation between the mounting hole and the elastic mounting pin.

[0018] In the lug assembly, a positioning structure positions the two lug covers, achieving pre-fixation between them; simultaneously, the two lug covers fix the spring-loaded mounting pin. A first limiting structure and a second limiting structure are provided to position the two lug covers along the longitudinal and transverse directions respectively, enabling rapid alignment and installation of the two lug covers.

[0019] Compared to existing technologies, the advantages of this utility model of a range hood are mainly reflected in the following: the hanging ear assembly is detachably mounted on the main body of the range hood, and the oil cup is detachably mounted on the hanging ear assembly, making disassembly and assembly convenient. The presence of a shielding part with a height greater than the oil cup allows for visual concealment of the oil cup, thus enabling it to be hidden from view.

[0020] This invention guides the movement of the oil cup through a guide channel, eliminating the need to adjust the position of the spring mounting pin and mounting hole during oil cup installation, thus enabling blind operation and simplifying oil cup installation. Attached Figure Description

However, the embodiments are not intended to limit this utility model. In this embodiment, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this utility model.

[0035] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to and integrated with the other element, or there may be an intervening element present. The terms "mounted," "one end," "the other end," and similar expressions used in this invention are for illustrative purposes only.

[0036] Example 1

[0037] This embodiment provides an oil cup mounting structure, such as Figure 1-4 As shown, the device includes an oil cup 1 and a hanging ear assembly 2. The hanging ear assembly 2 is provided with a spring mounting pin 3. The oil cup 1 is provided with a mounting hole 11. The oil cup 1 is detachably mounted on the spring mounting pin 3 through the mounting hole 11. A guide part 12 is provided on the oil cup 1. The guide part 12 is located above the mounting hole 11. The guide part 12 is bent outward from the end of the oil cup 1. The guide part 12 is provided with a guide channel 124. The guide channel 124 is used to compress the spring mounting pin 3 and guide the mounting hole 11 to move and cooperate with the spring mounting pin 3.

[0038] In this embodiment, the mounting holes 11 are provided at both ends of the oil cup 1; there are two hanging ear components 2, which are symmetrically arranged about the oil cup 1.

[0039] After the elastic mounting pin 3 is engaged with the mounting hole 11, the elastic mounting pin 3 passes through the mounting hole 11 and restricts the movement of the oil cup 1 in the radial direction of the elastic mounting pin 3; in this way, the movement of the oil cup 1 relative to the lug assembly 2 in the vertical direction can be restricted, as well as the movement of the oil cup 1 relative to the lug assembly 2 in the horizontal direction can be restricted. The guide channel 124 guides the mounting hole 11 to engage with the elastic mounting pin 3, guiding the movement of the oil cup 1. This ensures that the mounting hole 11 moves along the guide direction to achieve the most accurate alignment with the elastic mounting pin 3. This eliminates the need to adjust the position of the elastic mounting pin 3 and the mounting hole 11 during oil cup 1 installation, enabling blind operation and simplifying the installation process. Simultaneously, the guide part 12 is bent outwards, so that when the oil cup 1 moves, the elastic mounting pin 3 contacts the wall surface of the guide part 12, compressing the elastic mounting pin 3. Once the mounting hole 11 and the elastic mounting pin 3 are aligned, the elastic mounting pin 3 returns to its original position and extends into the mounting hole 11, connecting the two. The guide part 12 enables rapid installation between the oil cup 1 and the elastic mounting pin 3.

[0040] The guide portion 12 includes a first blocking surface 121, a second blocking surface 122, and a guide surface 123. The guide surface 123 is disposed between the first blocking surface 121 and the second blocking surface 122, and the outward bending amplitude of the guide surface 123 is greater than the bending amplitude of the first blocking surface 121 and the second blocking surface 122. A guide channel 124 is formed between the first blocking surface 121, the guide surface 123, and the second blocking surface 122. In a preferred embodiment, the first blocking surface 121, the second blocking surface 122, and the guide surface 123 are integrally formed. In the guide section 12, the guide surface 123 abuts against the elastic mounting pin 3, causing the elastic mounting pin 3 to be compressed; the first blocking surface 121 and the second blocking surface 122 respectively cooperate with the elastic mounting pin 3 to restrict the movement of the oil cup 1 along the width direction; thus, when installing the oil cup 1, the oil cup 1 can only move along the guide direction of the guide channel 124, which facilitates the cooperation between the mounting hole 11 and the elastic mounting pin 3.

[0041] The ear-mount assembly 2 includes two ear-mount covers, which are stacked and detachably connected. The elastic mounting pin 3 is disposed between the two ear-mount covers. A positioning structure is provided between the two ear-mount covers for connecting and positioning them. The positioning structure includes a first limiting structure 23 and a second limiting structure 24. The first limiting structure 23 is used for longitudinal positioning of the two ear-mount covers. The second limiting structure 24 is used for lateral positioning of the two ear-mount covers.

[0042] The first limiting structure 23 includes a first positioning flange 231 and a first positioning recess 232. The first positioning flange 231 is disposed on one ear cover plate; the first positioning recess 232 is disposed on another ear cover plate; and the first positioning flange 231 is disposed in the first positioning recess 232.

[0043] The second limiting structure 24 includes a second positioning flange 241 and a second positioning recess 242. The second positioning flange 241 is disposed on one ear cover plate; the second positioning recess 242 is disposed on another ear cover plate; and the second positioning flange 241 is disposed in the second positioning recess 242.

[0044] The two ear covers are a first ear cover 21 and a second ear cover 22. The first ear cover 21 is positioned above the second ear cover 22. A first positioning flange 231 and a second positioning flange 241 are positioned on the first ear scraper. A first positioning recess 232 and a second positioning recess 242 are positioned on the second ear cover 22. In the ear assembly 2, the first ear cover 21 and the second ear cover 22 are positioned by the positioning structure to achieve pre-fixation between the first ear cover 21 and the second ear cover 22; at the same time, the elastic mounting pin 3 is fixed by the first ear cover 21 and the second ear cover 22. A first limiting structure 23 and a second limiting structure 24 are provided to position the first ear cover 21 and the second ear cover 22 along the longitudinal direction and the directional direction, respectively, to achieve quick alignment and installation of the first ear cover 21 and the second ear cover 22.

[0045] In a preferred embodiment, the first ear cover plate 21 is provided with a first groove 211 near the wall of the second ear cover plate 22, and the second ear cover plate 22 is provided with a second groove 221 near the wall of the first ear cover plate 21. The first groove 211 and the second groove 221 are used to accommodate the elastic mounting pin 3.

[0046] The elastic mounting pin 3 includes a mounting base 31 and a mounting pin 32 movable in the mounting base 31. The mounting base 31 and the mounting pin 32 are connected by a spring (not shown in the figure). A stop portion 33 protrudes outward from the peripheral wall of the mounting base 31 near the mounting pin 32. A first recess 212 is provided at one end of the first groove 211, and the cross-sectional width of the first recess 212 is greater than the cross-sectional width of the first groove 211. A second recess 222 is provided at one end of the second groove 221, and the cross-sectional width of the second recess 222 is greater than the cross-sectional width of the second groove 221. The first recess 212 and the second recess 222 are used to accommodate the stop portion 33. By setting the first recess 212 and the first groove 211, and the second recess 222 and the second groove 221 with different cross-sectional widths, the stop portion 33 is limited, preventing the elastic mounting pin 3 from falling out of the lug assembly 2.

[0047] In a preferred embodiment, a first through hole 213 is provided on the first ear cover plate 21, and a second through hole 223 is provided on the second ear assembly 2. When installing the ear assembly 2, it is installed on the threaded hole of the range hood body by passing a bolt through the second through hole 223 and the first through hole 213. The first through hole 213 and the second through hole 223 are countersunk holes.
