Description

Technical Field

[0001] This invention relates to the field of home appliance technology, and in particular to an installation mechanism and a range hood. Background Technology

[0002] A range hood is a kitchen appliance that purifies the kitchen environment. Installed above the stove, it quickly removes combustion waste and harmful fumes produced during cooking, expelling them outdoors, reducing pollution, and purifying the air. It is an indispensable household appliance in kitchen life. The oil cup, as an important component of the range hood, has the function of collecting grease.

[0003] Currently, the industry standard for grease cups is that they are suspended below the range hood body. During installation, the grease cup is inserted into a slot inside the range hood, and the insertion part on the grease cup mates with the slot inside the range hood to secure it. However, this installation method requires a high degree of fit between the insertion part and the slot, meaning that only range hoods with specially designed grease cups can be installed, thus limiting the range hood's installation options. Furthermore, special tools are needed to remove the grease cup from the range hood during cleaning or maintenance, making the process difficult. Summary of the Invention

[0004] Based on this, the first technical problem solved by the present invention is to provide an installation mechanism that facilitates the installation of the oil cup; at the same time, it makes the oil cup easy to disassemble, which is beneficial to improving the cleaning or maintenance efficiency of the oil cup.

[0005] The second technical problem solved by this invention is to provide a range hood that facilitates the installation and operation of the oil cup; at the same time, it makes the oil cup easy to disassemble, which helps to improve the cleaning or maintenance efficiency of the oil cup.

[0006] The technical solution is as follows:

[0007] The first technical problem mentioned above is solved by the following technical solution:

[0008] An installation mechanism includes: a mounting shell with an opening; a sliding seat slidably mounted inside the mounting shell, the sliding seat being used to push and engage with an installation component on an oil cup through the opening, the sliding seat having a first locking portion; a clamping structure passing through the opening and connected to the sliding seat, the clamping structure being used to clamp the installation component; and a locking member movably mounted inside the mounting shell, the locking member having a second locking portion. When the sliding seat is pushed to a first position, the clamping structure is in an open state; when the sliding seat is pushed to a second position, the first locking portion and the second locking portion are locked together, and the clamping structure is in a clamping state; when the sliding seat is pushed away from the second position, the first locking portion and the second locking portion are disengaged, and the first locking portion and the second locking portion are misaligned.

[0009] The installation mechanism described in this invention offers the following advantages compared to the prior art: During the oil cup installation process, the oil cup mounting component is placed against the sliding seat through the opening; the sliding seat is pushed, causing it to slide to the second position; when the sliding seat is in the second position, the clamping structure is in a clamping state, that is, the clamping structure clamps the oil cup mounting component. Furthermore, when the sliding seat is in the second position, the second locking part on the locking component engages with the first locking part, thus locking the sliding seat in the second position and preventing it from moving towards the first position due to gravity. This ensures the oil cup is stably fixed, facilitating the installation of the oil cup on the range hood. When the oil cup needs cleaning or maintenance, press the oil cup to push the sliding seat away from the second position. At this time, the second locking part will disengage from the first locking part, and the second locking part and the first locking part will be misaligned in the pushing direction of the sliding seat. That is, the second locking part and the first locking part are not in the same direction. Therefore, when the oil cup is released, the sliding seat will drive the oil cup to slide towards the first position under its own weight. When the sliding seat reaches the first position, the clamping structure is in the open state. That is, the clamping structure releases the oil cup's mounting parts, allowing the oil cup to completely detach from the range hood. In this way, the installation mechanism not only makes the installation of the oil cup simple, but also simplifies the disassembly of the oil cup, greatly improving the efficiency of cleaning or maintenance of the oil cup.

[0010] In one embodiment, the sliding seat has a misaligned portion, and a first elastic member is provided between the locking member and the inner wall of the mounting housing. The second locking portion abuts against the misaligned portion through the first elastic member. When the sliding seat is pushed away from the second position, the second locking portion slides on the misaligned portion and is misaligned with the first locking portion. This ensures stable and quick installation and removal of the oil cup on the mounting mechanism.

[0011] In one embodiment, the sliding seat is further provided with a first guide groove and a second guide groove located on opposite sides of the second locking portion. One end of the first guide groove and one end of the second guide groove are connected through the offset portion. The second locking portion moves from the second guide groove to the first locking portion through the offset portion; and / or moves from the first locking portion to the first guide groove. The other end of the first guide groove and the other end of the second guide groove are transitionally fitted. This ensures that the sliding of the second locking portion is more standardized and orderly, thereby ensuring that the installation and removal of the oil cup on the range hood are more stable.

[0012] In one embodiment, the staggered portion includes an inlet segment and an outlet segment, both of which are inclined. The end of the inlet segment near the second guide groove is higher than the end of the inlet segment near the first locking portion, and the end of the outlet segment near the first locking portion is higher than the end of the outlet segment near the first guide groove.

[0013] In one embodiment, the bottom of the first guide groove at the end away from the offset portion is higher than the bottom of the second guide groove at the end away from the offset portion, and the bottom of the first guide groove at the end away from the offset portion is inclined relative to the second guide groove.

[0014] In one embodiment, the clamping structure includes a first clamping member and a second clamping member that are both movably connected to the sliding seat. When the sliding seat is pushed to the first position, the first clamping member and the second clamping member move away from each other. When the sliding seat is pushed to the second position, the first clamping member and the second clamping member move closer to each other under the action of the inner wall of the opening.

[0015] In one embodiment, the mounting mechanism further includes a guide member located within the mounting housing. The guide member has a first guide portion. Both the first clamping member and the second clamping member are rotatably connected to the sliding seat. The first clamping member and / or the second clamping member have second guide portions that guide and cooperate with the first guide portion. This allows the first clamping member and / or the second clamping member to rotate smoothly, improving the clamping stability of the clamping structure on the oil cup.

[0016] In one embodiment, the mounting mechanism further includes a reset member disposed between the sliding seat and the inner wall of the mounting housing. Thus, under the action of the reset member, the sliding seat will automatically move to the first position, making the disassembly of the oil cup smoother.

[0017] In one embodiment, the mounting mechanism further includes a first conductive element and a second conductive element spaced apart within the mounting housing. When the sliding seat is pushed to the second position, the first conductive element makes conductive contact with the second conductive element under the pressure of the sliding seat. The first conductive element is used to connect to an external power source, and the second conductive element is used to connect to the power source of the range hood. This ensures the range hood is in a power-off safety state, guaranteeing user safety during cleaning.

[0018] The second technical problem mentioned above is solved by the following technical solution:

[0019] A range hood includes a range hood body, an oil cup, and an installation mechanism as described in any one of the above. The installation mechanism has an installation port and is installed in the range hood body. The opening is opposite to the installation port. The oil cup has an installation component. When the oil cup is inserted into the installation port and the sliding seat is pushed to the second position, the clamping structure clamps the installation component.

[0020] The range hood of the present invention offers the following advantages compared to the prior art: Using the above-described installation mechanism, during the installation of the oil cup, the oil cup mounting component is placed against the sliding seat through the opening; the sliding seat is pushed, causing it to slide to the second position; when the sliding seat is in the second position, the clamping structure is in a clamping state, that is, the clamping structure clamps the oil cup mounting component. Furthermore, when the sliding seat is in the second position, the second locking part on the locking component engages with the first locking part, thus locking the sliding seat in the second position and preventing it from moving towards the first position due to gravity. This ensures the oil cup is stably fixed and facilitates the installation of the oil cup on the range hood. When the oil cup needs cleaning or maintenance, press the oil cup to push the sliding seat away from the second position. At this time, the second locking part will disengage from the first locking part, and the second locking part and the first locking part will be misaligned in the pushing direction of the sliding seat. That is, the second locking part and the first locking part are not in the same direction. Therefore, when the oil cup is released, the sliding seat will drive the oil cup to slide towards the first position under its own weight. When the sliding seat reaches the first position, the clamping structure is in the open state. That is, the clamping structure releases the oil cup's mounting parts, allowing the oil cup to completely detach from the range hood. In this way, the installation mechanism not only makes the installation of the oil cup simple, but also simplifies the disassembly of the oil cup, greatly improving the efficiency of cleaning or maintenance of the oil cup.

[0021] In one embodiment, the range hood further includes a detection component installed within the range hood body. This detection component is used to detect the amount of oil in the oil cup. Thus, by accurately detecting the amount of oil in the oil cup, the user is promptly reminded to empty any excess oil. Attached Figure Description

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0038] In this invention, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0039] In one embodiment, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 An installation mechanism 100 includes: a mounting shell 110, a sliding seat 120, a clamping structure 130, and a locking member 140. The mounting shell 110 has an opening 113. The sliding seat 120 is slidably mounted inside the mounting shell 110 and is used to push and engage with the mounting member 210 on the oil cup 200 through the opening 113. The sliding seat 120 has a first locking part 121. The clamping structure 130 passes through the opening 113 and is connected to the sliding seat 120. The clamping structure 130 is used to clamp the mounting member 210. The locking member 140 is movably mounted inside the mounting shell 110 and has a second locking part 141. When the sliding seat 120 is pushed to a first position, the clamping structure 130 is in an open state. When the sliding seat 120 is pushed to a second position, the first locking part 121 and the second locking part 141 are locked together, and the clamping structure 130 is in a clamping state. When the sliding seat 120 is pushed away from the second position, the first locking part 121 and the second locking part 141 are disengaged and misaligned.

[0040] During the installation of the oil cup 200, the aforementioned installation mechanism 100 places the mounting part 210 of the oil cup 200 against the sliding seat 120 through the opening 113; pushes the sliding seat 120, causing it to slide to the second position; when the sliding seat 120 is in the second position, the clamping structure 130 is in a clamping state, that is, the clamping structure 130 clamps the mounting part 210 of the oil cup 200. Furthermore, when the sliding seat 120 is in the second position, the second locking part 141 on the locking member 140 engages with the first locking part 121, thus locking the sliding seat 120 in the second position, preventing it from moving towards the first position due to gravity, thereby ensuring the oil cup 200 is stably fixed and facilitating its installation on the range hood. When the oil cup 200 needs cleaning or maintenance, press the oil cup 200 to push the sliding seat 120 away from the second position. At this time, the second locking part 141 will disengage from the first locking part 121, and the second locking part 141 and the first locking part 121 will be misaligned in the pushing direction of the sliding seat 120. That is, the second locking part 141 and the first locking part 121 are not in the same direction. Therefore, when the oil cup 200 is released, the sliding seat 120 will slide the oil cup 200 towards the first position under its own weight. When the sliding seat 120 reaches the first position, the clamping structure 130 is in the open state. That is, the clamping structure 130 releases the mounting part 210 of the oil cup 200, so that the oil cup 200 is completely removed from the range hood. In this way, the installation mechanism 100 not only makes the installation operation of the oil cup 200 simple, but also simplifies the disassembly operation of the oil cup 200, greatly improving the cleaning or maintenance efficiency of the oil cup 200.

[0041] It should be noted that the locking member 140 in this embodiment is rotatably installed inside the mounting housing 110. Therefore, when the sliding seat 120 slides to the first position, the locking member 140 can be in its initial state by its own weight or other guiding structures, such as guide blocks or guide grooves, so that the locking member 140 can be used for subsequent oil cup 200 installation operations.

[0042] It should also be noted that the misalignment of the first locking part 121 and the second locking part 141 should be understood as follows: when the sliding seat 120 is pushed away from the second position, the second locking part 141 is misaligned on the sliding seat 120, so that the second locking part 141 and the first locking part 121 are misaligned in the pushing direction of the sliding seat 120, so as to prevent the second locking part 141 from locking with the first locking part 121 again when the sliding seat 120 slides back to the first position.

[0043] Optionally, when the sliding seat 120 is pushed away from the second position, the second locking part 141 can be misaligned from the first locking part 121 in the following ways: An inclined surface is provided in front of the first locking part 121, causing the second locking part 141 to shift on the sliding seat 120, thus misaligning the second locking part 141 with the first locking part 121; or, an arc-shaped block is provided in front of the first locking part 121, causing the second locking part 141 to shift on the sliding seat 120; or, a rack is installed on the sliding seat 120, and opposing gears and levers are provided inside the mounting housing 110. When the sliding seat 120 slides to the second position, the rack and gears mesh, driving the lever to rotate, thereby disengaging the second locking part 141. Of course, the disengaged second locking part 141 can maintain its misaligned state with the first locking part 121 through friction with the sliding seat 120.

[0044] Optionally, this embodiment does not limit the specific construction of the clamping structure 130, as long as the clamping structure 130 is in the open state at the first position and in the clamping state at the second position. For example, the clamping structure 130 is divided into two clamping parts 211. When the two clamping parts 211 are inserted into or out of the opening 113, the two clamping parts 211 are clamped and opened by the action of the side wall of the opening 113; or, the sliding seat 120 and the two clamping parts 211 are all provided with racks, and a gear is provided between the sliding seat 120 and the clamping parts 211. Through the combination of gear and rack, the sliding of the sliding seat 120 is converted into the clamping and opening of the two clamping parts 211.

[0045] Further, please refer to Figure 2 , Figure 4 and Figure 7The sliding seat 120 is provided with a misaligned portion 122. The locking member (140) is rotatably installed in the mounting shell (110). A first elastic member 143 is provided between the locking member 140 and the inner wall of the mounting shell 110. The second locking portion 141 abuts against the misaligned portion 122 through the first elastic member 143. When the sliding seat 120 is pushed away from the second position, the second locking portion 141 slides on the misaligned portion 122 and is misaligned with the first locking portion 121. Therefore, when the sliding seat 120 is in the second position, the sliding seat 120 is pushed further, causing the second locking part 141 to slide on the offset part 122. Since the second locking part 141 abuts against the offset part 122 through the first elastic member 143, and the locking member 140 is rotatably disposed within the mounting housing 110, under the combined action of the offset part 122 and the first elastic member 143, the second locking part 141 is misaligned relative to the first locking part 121. This misalignment is maintained by the abutting action between the second locking part 141 and the offset part 122, preventing the second locking part 141 from moving back to the position opposite to the first locking part 121 and locking again when the sliding seat 120 slides to the first position. In this way, the oil cup 200 is stably and quickly installed and removed from the mounting mechanism 100.

[0046] Optionally, in this embodiment, the top surface of the offset portion 122 facing away from the sliding seat 120 is an inclined surface, or the side surface of the offset portion 122 facing the first locking portion 121 is an inclined surface. When the top surface of the offset portion 122 facing away from the sliding seat 120 is an inclined surface, the inclined surface is inclined along the pushing direction perpendicular to or substantially perpendicular to the sliding seat 120. At this time, the second locking portion 141 slides on the inclined surface. Since the second locking portion 141 is always subjected to the pushing force of the first elastic member 143, the second locking portion 141 can easily slide along the inclined surface on the offset portion 122, causing the second locking portion 141 to be offset from the first locking portion 121. When the side surface of the offset portion 122 facing the first locking portion 121 is an inclined surface, the second locking portion 141 will abut against this side surface, and under the action of the inclined surface, the locking member 140 will rotate, thereby causing the second locking portion 141 to be offset from the first locking portion 121. In order to facilitate understanding of the pushing direction of the slider 120 in this embodiment, Figure 2 For example, the pushing direction of the sliding seat 120 is Figure 2 The direction indicated by S in the middle.

[0047] Optionally, the first elastic element 143 is an elastic metal sheet, an elastic rubber element, a spring, or other elastic object.

[0048] Furthermore, please refer to Figure 7The sliding seat 120 is also provided with a first guide groove 123 and a second guide groove 124 located on opposite sides of the second locking portion 141. One end of the first guide groove 123 and one end of the second guide groove 124 are connected by a misalignment portion 122. The second locking portion 141 is transferred from the second guide groove 124 to the first locking portion 121 via the misalignment portion 122; and / or, from the first locking portion 121 to the first guide groove 123. The other end of the first guide groove 123 is transitionally fitted with the other end of the second guide groove 124. Therefore, when the sliding seat 120 is pushed away from the second position, the second locking part 141, under the action of the offset part 122, moves from the first locking part 121 to the first guide groove 123, causing the second locking part 141 to disengage from the first locking part 121 and be offset; then, the sliding seat 120 is released, causing the sliding seat 120 to slide towards the first position under its own weight or the action of other structures. At this time, the second locking part 141 moves along the first guide groove 123 on the sliding seat 120. Since one end of the first guide groove 123 and one end of the second guide groove 124 are transitionally fitted, when the sliding seat 120 moves to the second position under the push of the oil cup 200, the second locking part 141 transfers from the first guide groove 123 to the second guide groove 124 and moves along the second guide groove 124; when the sliding seat 120 is pushed to the second position, the second locking part 141, under the action of the offset part 122, transfers from the second guide groove 124 to the first locking part 121, so that the second locking part 141 locks on the first locking part 121, thereby completing the fixed installation of the oil cup 200. In addition, in this embodiment, the first guide groove 123 and the second guide groove 124 are respectively provided on the fixed seat 114 to ensure that the sliding of the second locking part 141 is more standardized and orderly, thereby ensuring that the installation and removal of the oil cup 200 on the range hood is more stable.

[0049] In one embodiment, please refer to Figure 7 The staggered portion 122 includes an inlet section 1222 and an outlet section 1221, both of which are inclined. The end of the inlet section 1222 near the second guide groove 124 is higher than the end of the inlet section 1222 near the first locking portion 121. The end of the outlet section 1221 near the first locking portion 121 is higher than the end of the outlet section 1221 near the first guide groove 123. Thus, by designing the inlet section 1222 and the outlet section 1221 as inclined surfaces, the second locking portion 141 can be smoothly transferred from the second guide groove 124 to the first locking portion 121 and from the first locking portion 121 to the first guide groove 123, thereby enabling stable unlocking and locking operations between the locking member 140 and the sliding seat 120.

[0050] Further, please refer to Figure 7The end of the inlet segment 1222 near the first locking part 121 is higher than the end of the outlet segment 1221 near the first locking part 121. That is, there is a height difference between the inlet segment 1222 and the outlet segment 1221. Thus, when the sliding seat 120 is pushed away from the second position, the second locking part 141 will disengage from the first locking part 121 and move towards the first position. Since there is a height difference between the inlet segment 1222 and the outlet segment 1221, the part of the inlet segment 1222 that is higher than the outlet segment 1221 will block the second locking part 141 from continuing to move, and cause the second locking part 141 to shift along the slope of the outlet segment 1221 into the first guide groove 123, thereby making it easier for the second locking part 141 to transfer into the first guide groove 123. Meanwhile, due to the height difference between the inlet section 1222 and the outlet section 1221, when the second locking part 141 slides down from the inlet section 1222, it will impact the outlet section 1221 or the part of the sliding seat 120 near the first locking part 121, producing a sound. The user can then determine whether the second locking part 141 is locked to the first locking part 121 by this sound. Furthermore, the height difference between the inlet section 1222 and the outlet section 1221 ensures that the locking member 140 rotates in a fixed direction, preventing reverse rotation.

[0051] In one specific embodiment, please refer to Figure 7 The first locking part 121 is a concave structure, and the two side walls of the concave structure are set at an included angle. Therefore, it can be seen that the first locking part 121 in this embodiment is in or approximately in a "V" shape, which makes it easier for the second locking part 141 to slide into the first locking part 121 from the second guide groove 124.

[0052] In one embodiment, please refer to Figure 7The bottom of the first guide groove 123 away from the offset portion 122 is higher than the bottom of the second guide groove 124 away from the offset portion 122, and the bottom of the first guide groove 123 away from the offset portion 122 is inclined relative to the second guide groove 124. Therefore, when the sliding seat 120 is in the first position, the second locking portion 141 is located at the end of the first guide groove 123 away from the offset portion 122. Since the bottom of one end of the first guide groove 123 is inclined relative to the second guide groove 124, and the first elastic member 143 is provided between the locking member 140 and the inner wall of the mounting shell 110, as the sliding seat 120 slides to the second position, under the pushing of the first elastic member 143, the second locking part 141 will slide along its inclined surface on the bottom of the first guide groove 123 into the second guide groove 124, and slide along the second guide groove 124 towards the first locking part 121. In this way, the second locking part 141 is smoothly transferred from the first guide groove 123 to the second guide groove 124, so that the second locking part 141 repeatedly moves in a circular motion between the installation and disassembly operations of the oil cup 200.

[0053] It should be noted that the bottom of the first guide groove 123, which is away from the offset part 122, is inclined relative to the second guide groove 124. This should be understood as the bottom of the first guide groove 123 being lower on the sliding seat 120 as it gets closer to the second guide groove 124.

[0054] Specifically, the end of the first guide groove 123 away from the first locking part 121 is higher than the end of the second guide groove 124 away from the first locking part 121. At the same time, the bottom of the end of the second guide groove 124 away from the first locking part 121 is also inclined.

[0055] In one embodiment, please refer to Figure 1 and Figure 3 The clamping structure 130 includes a first clamping member 131 and a second clamping member 132, both movably connected to the sliding seat 120. When the sliding seat 120 is pushed to the first position, the first clamping member 131 and the second clamping member 132 move away from each other. When the sliding seat 120 is pushed to the second position, the first clamping member 131 and the second clamping member 132 move closer to each other under the action of the inner wall of the opening 113. Therefore, when the sliding seat 120 is in the first position, the first clamping member 131 and the second clamping member 132 are far apart from each other, so that the clamping structure 130 is in the open state, which makes it easy to remove the oil cup 200. When the sliding seat 120 is in the second position, the first clamping member 131 and the second clamping member 132 are pulled into the mounting shell 110 from the opening 113 by the sliding seat 120. Since the first clamping member 131 and the second clamping member 132 are limited by the width of the opening 113, the first clamping member 131 and the second clamping member 132 move closer to each other under the action of the opening 113, so that the clamping structure 130 is in the clamping state, thereby making the oil cup 200 stably installed.

[0056] Optionally, the first clamping member 131 and the second clamping member 132 are movably connected to the sliding seat 120 in the following ways: both the first clamping member 131 and the second clamping member 132 are rotatably connected to the sliding seat 120; or, both the first clamping member 131 and the second clamping member 132 are slidably connected to the sliding seat 120, so that the first clamping member 131 and the second clamping member 132 move closer to each other or further apart. Of course, in order to make the first clamping member 131 and the second clamping member 132 move closer to each other when the sliding seat 120 moves within the mounting shell 110, inclined strips, i.e., triangular strip structures, can be provided on the outer sides of both the first clamping member 131 and the second clamping member 132.

[0057] Further, please refer to Figure 2 and Figure 4 The mounting mechanism 100 also includes a guide member 150 located inside the mounting housing 110. The guide member 150 is provided with a first guide portion 151. The first clamping member 131 and the second clamping member 132 are both rotatably connected to the sliding seat 120. The first clamping member 131 and / or the second clamping member 132 are provided with a second guide portion 133 that guides and cooperates with the first guide portion 151. Therefore, during the installation of the oil cup 200, the mounting part 210 of the oil cup 200 passes through the opening 113 and abuts against the sliding seat 120, and the sliding seat 120 is pushed to the second position. At this time, the first clamping part 131 and the second clamping part 132, driven by the sliding seat 120, also pass through the opening 113 and enter the mounting shell 110. Due to the abutment of the two side walls of the opening 113 against the first clamping part 131 and the second clamping part 132, the first clamping part 131 and the second clamping part 132 rotate and move closer to each other. When the sliding seat 120 is pushed to the second position, the first clamping part 131 and the second clamping part 132 cooperate to clamp the mounting part 210, thereby achieving the fixed installation of the oil cup 200. Since the mounting housing 110 is provided with a guide member 150, and the guide member 150 is provided with a first guide part 151, the first guide part 151 cooperates with the second guide part 133 to make the first clamping member 131 and / or the second clamping member 132 rotate smoothly, thereby improving the clamping stability of the clamping structure 130 on the oil cup 200.

[0058] Optionally, the first guide portion 151 is a guide groove and the second guide portion 133 is a guide bar; or, the first guide portion 151 is a guide bar and the second guide portion 133 is a guide groove.

[0059] Furthermore, please refer to Figure 5 and Figure 6The mounting housing 110 is provided with two first mounting grooves 117, which are located on opposite sides of the opening 113. The guide 150 is inserted into the first mounting groove 117, so that the guide 150 is stably installed, thereby stably guiding the first clamping member 131 and the second clamping member 132.

[0060] In one embodiment, please refer to Figure 5 and Figure 7 The sliding seat 120 is provided with a mounting seat 126. The mounting seat 126 is provided with a first rotating shaft 1261 and a second rotating shaft 1262 spaced apart. The first clamping member 131 is rotatably connected to the first rotating shaft 1261, and the second clamping member 132 is rotatably connected to the second rotating shaft 1262. In this way, the first clamping member 131 and the second clamping member 132 can rotate stably.

[0061] Further, please refer to Figure 7 The mounting base 126 is provided with an abutment part 1263, which is used to abut against the mounting part 210. In this way, the oil cup 200 can stably push the sliding seat 120 through the abutment part 1263 and the mounting part 210.

[0062] In one embodiment, please refer to Figure 7 The first clamping member 131 is provided with a first groove 1311, and the second clamping member 132 is provided with a second groove 1321. The first groove 1311 and the second groove 1321 are respectively adapted to the side of the mounting member 210. In this way, the first clamping member 131 and the second clamping member 132 are more tightly connected with the mounting member 210, ensuring that the oil cup 200 is more stably installed on the range hood.

[0063] Specifically, both the first groove 1311 and the second groove 1321 are arc surfaces, and the clamping part 211 on the mounting part 210 is or is approximately spherical.

[0064] In one embodiment, please refer to Figure 5 A second elastic member 1312 is provided between the first clamping member 131 and the sliding seat 120, and a third elastic member 1322 is provided between the second clamping member 132 and the sliding seat 120. Thus, through the second elastic member 1312 and the third elastic member 1322, the first clamping member 131 and the second clamping member 132 can automatically open, thereby making it easier for the oil cup 200 to detach from the range hood.

[0065] Specifically, the second elastic element 1312 and the third elastic element 1322 are both torsion springs. The torsion springs are sleeved on the first rotating shaft 1261 and the second rotating shaft 1262. One end of the torsion spring abuts against the sliding seat 120, and the other end of the torsion spring abuts against the first clamping member 131 or the second clamping member 132.

[0066] In one embodiment, please refer to Figure 2 and Figure 4 The mounting mechanism 100 also includes a reset member 180. The reset member 180 is disposed between the sliding seat 120 and the inner wall of the mounting housing 110. Thus, when the first locking part 121 and the second locking part 141 are disengaged, the sliding seat 120 will automatically move to the first position under the action of the reset member 180, making the disassembly of the oil cup 200 smoother.

[0067] Optionally, the reset element 180 may be a spring, an elastic rubber element, an elastic metal sheet, or other elastic material.

[0068] Further, please refer to Figure 2 The reset element 180 is a spring, and the sliding seat 120 is provided with a guide post 127. One end of the spring is sleeved on the guide post 127, and the other end of the spring abuts against the inner wall of the mounting shell 110. In this way, the spring will not bend or deform during the extension or compression process, so that the spring is stable between the sliding seat 120 and the inner wall of the mounting shell 110.

[0069] For details, please refer to Figure 5 , Figure 6 and Figure 7 The sliding seat 120 is provided with a first recess 125, and the guide post 127 is disposed on the inner wall of the first recess 125. At the same time, the inner wall of the mounting shell 110 is provided with a side stop 115, and the side stop 115 and the mounting inner wall form a second recess 116, and one end of the spring is located in the second recess 116.

[0070] In one embodiment, please refer to Figure 2 and Figure 4The installation mechanism 100 also includes a first conductive element 160 and a second conductive element 170 spaced apart within the installation housing 110. When the sliding seat 120 is pushed to the second position, the first conductive element 160 makes conductive contact with the second conductive element 170 under the pressure of the sliding seat 120. The first conductive element 160 is used to connect to an external power source, and the second conductive element 170 is used to connect to the power source of the range hood. Therefore, during the installation of the oil cup 200, the oil cup 200 is pressed against the sliding seat 120, and the sliding seat 120 is pushed to slide to the second position. During the sliding process, the sliding seat 120 will press the first conductive element 160, causing it to deform and make conductive contact with the second conductive element 170, thereby connecting the range hood to the power source and ensuring that the range hood automatically starts during the installation of the oil cup 200. Meanwhile, when the oil cup 200 needs cleaning or maintenance, the sliding seat 120 moves to the first position, so that the sliding seat 120 is not in contact with the first conductive element 160. At this time, the first conductive element 160 loses the squeezing force of the sliding seat 120, so that the first conductive element 160 is disconnected from the second conductive element 170, thereby putting the range hood in a power-off safety state to ensure the safety of users during the cleaning process.

[0071] It should be noted that the first conductive element 160 in this embodiment is an elastic conductive element with a certain elastic function. When the sliding seat 120 is no longer pressing the first conductive element 160, the first conductive element 160 can disconnect from the second conductive element 170 by relying on its own elastic function.

[0072] It should also be noted that in this embodiment, the external power source is the live wire of the indoor power source, which serves as the input end of the power cord; meanwhile, the range hood power source is the live wire of the range hood power source, which serves as the output end of the power cord.

[0073] Optionally, both the first conductive element 160 and the second conductive element 170 can be made of metal materials with high electrical conductivity, good elasticity, and high thermal conductivity, such as brass, silver tin oxide, and silver nickel.

[0074] Further, please refer to Figure 6 The inner wall of the mounting housing 110 is provided with a first slot 118 and a second slot 119 spaced apart. The first conductive component 160 and the second conductive component 170 are respectively inserted into the first slot 118 and the second slot 119, which makes the installation of the first conductive component 160 and the second conductive component 170 more convenient.

[0075] In one embodiment, please refer to Figure 6 The mounting housing 110 is provided with a fixing seat 114, the fixing seat 114 is provided with a socket 1141, and the locking member 140 is provided with an insertion part 142. The insertion part 142 is inserted into the socket 1141, so that the locking member 140 is stably installed in the mounting housing 110; at the same time, it ensures that the locking member 140 can rotate stably in the mounting housing 110.

[0076] Specifically, the locking element 140 has a U-shaped structure. The material of the locking element 140 can be metal, plastic, wood, etc.

[0077] In one embodiment, please refer to Figure 5 The mounting housing 110 includes a base 111 and a pressure cover 112 covering the base 111. The sliding seat 120 and the locking member 140 are both mounted on the base 111. Meanwhile, the first elastic member 143 is disposed between the locking member 140 and the pressure cover 112.

[0078] Further, please refer to Figure 5 and Figure 6 The base 111 is provided with a first snap-fit ​​part 1111, and the cover 112 is provided with a second snap-fit ​​part 1121 that snaps into the first snap-fit ​​part 1111. Thus, the assembly operation of the mounting shell 110 is made more convenient through the first snap-fit ​​part 1111 and the second snap-fit ​​part 1121, which helps to improve the assembly efficiency of the mounting mechanism 100.

[0079] Optionally, the first latching portion 1111 is a protrusion and the second latching portion 1121 is a groove; or, the first latching portion 1111 is a groove and the second latching portion 1121 is a protrusion.

[0080] In one embodiment, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 A range hood includes a range hood body 300, an oil cup 200, and a mounting mechanism 100 as described in any of the above embodiments. The mounting mechanism 100 has an installation port 321. The mounting mechanism 100 is installed inside the range hood body 300, with its opening 113 opposite to the installation port 321. The oil cup 200 has a mounting member 210. When the oil cup 200 is inserted into the installation port 321 and the sliding seat 120 is pushed to a second position, the clamping structure 130 clamps the mounting member 210.

[0081] The aforementioned range hood, employing the aforementioned mounting mechanism 100, during the installation of the oil cup 200, places the mounting part 210 of the oil cup 200 against the sliding seat 120 through the opening 113; pushing the sliding seat 120 causes it to slide to the second position; when the sliding seat 120 is in the second position, the clamping structure 130 is in a clamping state, that is, the clamping structure 130 clamps the mounting part 210 of the oil cup 200. Furthermore, when the sliding seat 120 is in the second position, the second locking part 141 on the locking member 140 engages with the first locking part 121, thus locking the sliding seat 120 in the second position, preventing it from moving towards the first position due to gravity, thereby ensuring the oil cup 200 is stably fixed and facilitating its installation on the range hood. When the oil cup 200 needs cleaning or maintenance, press the oil cup 200 to push the sliding seat 120 away from the second position. At this time, the second locking part 141 will disengage from the first locking part 121, and the second locking part 141 and the first locking part 121 will be misaligned in the pushing direction of the sliding seat 120. That is, the second locking part 141 and the first locking part 121 are not in the same direction. Therefore, when the oil cup 200 is released, the sliding seat 120 will slide the oil cup 200 towards the first position under its own weight. When the sliding seat 120 reaches the first position, the clamping structure 130 is in the open state. That is, the clamping structure 130 releases the mounting part 210 of the oil cup 200, so that the oil cup 200 is completely removed from the range hood. In this way, the installation mechanism 100 not only makes the installation operation of the oil cup 200 simple, but also simplifies the disassembly operation of the oil cup 200, greatly improving the cleaning or maintenance efficiency of the oil cup 200. In addition, since the mounting mechanism 100 is installed inside the range hood, the oil cup 200 needs to be inserted through the opening 113 and installed on the mounting mechanism 100. In this way, the oil cup 200 is completely inside the range hood, achieving the effect of hiding the oil cup 200 on the range hood.

[0082] Specifically, when the oil cup 200 is installed on the mounting mechanism 100, the bottom surface of the oil cup 200 is kept or basically kept on the same plane as the bottom surface of the range hood body 300, which greatly improves the overall effect of the range hood.

[0083] Further, please refer to Figure 9 and Figure 10 The range hood also includes a detection component 400. The detection component 400 is installed inside the range hood body 300 and is used to detect the amount of oil in the oil cup 200. In this way, the detection component 400 can accurately detect the amount of oil in the oil cup 200 and promptly remind the user to empty the excess oil.

[0084] Optionally, this embodiment does not specifically limit the detection component 400, as long as it can detect the oil quantity in the oil cup 200.

[0085] Specifically, the detection component 400 is a photoelectric liquid level sensor, which utilizes the principle of light reflection and refraction at the interface of two different media. Its working logic is as follows: when the oil level has not reached the designated position, the photoelectric liquid level sensor is in the air medium, and the output electrical signal is zero; when the oil level reaches the designated position, the photoelectric liquid level sensor is in the oil medium, and the output electrical signal is non-zero; after receiving this electrical signal, the range hood's electronic control system will issue an audible or visual prompt to remind the user to empty the oil in time.

[0086] In one embodiment, please refer to Figure 11 The mounting component 210 includes a fixing part 212 and a clamping part 211 connected to the fixing part 212. The clamping structure 130 clamps and engages with the clamping part 211, and the fixing part 212 is connected to the oil cup 200. The connection method between the fixing part 212 and the oil cup 200 can be bolt connection, screw connection, welding, bonding, riveting, or other connection methods.

[0087] Further, please refer to Figure 11 The oil cup 200 is provided with a second mounting groove 220, and the fixing part 212 is installed on the bottom wall of the second mounting groove 220. This helps to improve the installation stability of the mounting part 210 on the oil cup 200.

[0088] In one embodiment, please refer to Figure 8 The range hood body 300 includes a body 310 and a smoke extraction structure 320. The smoke extraction structure 320 is vertically mounted on the body 310. The smoke extraction structure 320 has a smoke inlet 322, an installation port 321, and an installation mechanism 100. Thus, when smoke enters through the smoke inlet 322, grease flows down the smoke extraction structure 320 into the grease cup 200. Because the smoke extraction structure 320 is vertically mounted on the body 310, it can be retracted into the body 310 when not in use, reducing the space occupied by the range hood.

[0089] Optionally, this embodiment does not specifically limit the lifting method of the smoking structure 320, as long as it satisfies the lifting requirement of the smoking structure 320. For example, it can use a linear module, cylinder, hydraulic cylinder, motor and crank structure, motor and rack, motor and traction rope, etc.

[0090] Further, please refer to Figure 8 The smoke extraction structure 320 is equipped with an openable smoke hood 323, which covers the smoke extraction port 322. In this way, the smoke hood 323 ensures that the range hood is in a closed state when it is not working.

[0091] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0092] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
