[0035] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0036] See also Figures 1 to 9The utility model discloses a range hood with a hidden oil cup. The range hood with a hidden oil cup disclosed by the utility model comprises a range hood main body 1, a telescopic component 2 and an oil cup component 3. The range hood main body 1 has a back plate 11; the driving end of the telescopic component 2 has an extended state and a retracted state; the oil cup component 3 is connected to the driving end of the telescopic component 2; when the driving end of the telescopic component 2 is in the retracted state, the oil cup component 3 is hidden behind the back plate 11, and when the oil cup component 3 is pushed upward, the oil cup component 3 presses the driving end of the telescopic component 2 upward, the telescopic component 2 switches to the extended state, and the oil cup component 3 extends out from under the back plate 11; when the telescopic component 2 is in the extended state, when the oil cup component 3 is pushed upward, the oil cup component 3 presses the driving end of the telescopic component 2 upward, the telescopic component 2 switches back to the retracted state, and the oil cup component 3 is hidden back behind the back plate 11. In the range hood with a hidden oil cup of the utility model, under normal conditions, the oil cup assembly 3 is hidden behind the back plate 11, and the oil cup assembly 3 cannot be seen from the user side. The machining accuracy requirement for the assembly position of the oil cup assembly 3 becomes lower. When the oil in the oil cup assembly 3 needs to be cleaned, the user applies an upward thrust to the bottom of the oil cup assembly 3, and the oil cup assembly 3 squeezes the driving end of the telescopic assembly 2 upward, and the telescopic assembly 2 switches to the extended state, extending the oil cup assembly 3 from under the back plate 11, making it convenient for the user to remove the oil cup assembly 3 from the telescopic assembly 2.

[0037] See also Figures 3 to 10The utility model has a range hood with a hidden oil cup, and the telescopic assembly 2 includes a slide seat 21, a push rod 22 and a compression spring 23. The slide seat 21 is connected to the inner side of the back plate 11, and has a slideway. A hook 24 located in the slideway is provided on the top of the slide seat. A slide groove 221 is provided at the upper end of the push rod 22, and a limit block 222 is provided in the slide groove 221. The compression spring 23 is sleeved on the push rod 22, and the push rod 22 is slidably connected in the slideway, and its lower end is connected to the oil cup assembly 3 and forms the driving end of the telescopic assembly 2. When the driving end of the telescopic assembly 2 is in a retracted state, the hook 24 is hung on the limit block 222, and the compression spring 23 is compressed. When the driving end of the telescopic assembly 2 is in an extended state, the hook 24 slides out of the slide groove 221, and the compression spring 23 resets and pushes the push rod 22 downward. When the oil cup assembly 3 is hidden behind the back plate 11, if the oil cup needs to be cleaned, the user applies an upward thrust to the bottom of the oil cup assembly 3. Under the action of the thrust, the hook 24 slides along the slide groove 221 and leaves the limit block 222. The force of the hook 24 on the push rod 22 disappears, and the force applied by the hook 24 to the compression spring 23 through the push rod 22 disappears. The compression spring 23 resets and pushes the push rod 22 to slide down the slideway. The lower end of the push rod 22 moves downward relative to the slide seat 21, and the oil cup assembly 3 moves with the push rod 22. Move downward and extend below the back plate 11; after the oil in the oil cup assembly 3 is cleaned, the user connects the oil cup assembly 3 with the lower end of the push rod 22, and then the user pushes the oil cup assembly 3 upward. Under the force of the oil cup assembly 3, the push rod 22 moves upward along the slideway and compresses the compression spring 23. The hook 24 slides relatively with the limit block 222 in the slide groove 221. When the hook 24 is hooked with the limit block 222 again, the push rod 24 rises to its position, and the oil cup assembly 3 is hidden behind the back plate 11 again. In the utility model of the range hood with hidden oil cup, the oil cup assembly 3 is hidden behind the back plate 11, and the machining accuracy of the gap between the oil cup assembly 3 and the range hood body is reduced without affecting the appearance of the range hood. When the oil cup assembly 3 needs to be cleaned, the telescopic assembly 2 can extend the oil cup assembly 3 without affecting the user's disassembly of the oil cup assembly 3.

[0038] See also Figures 3 to 10In the utility model of the range hood with hidden oil cup, the bottom of the limit block 222 has a limit groove 2221. When the driving end of the telescopic assembly 2 is in the retracted state, the hook 24 is hooked in the limit groove 2221 of the limit block 222. The limit groove 2221 can make the connection between the hook 24 and the limit block 222 relatively stable, and prevent the hook 24 from leaving the limit block 222 when the oil cup assembly 3 is accidentally touched, so that the oil cup assembly 3 is extended from the back of the back plate 11 to the bottom of the back plate 11. At the same time, due to the existence of the limit groove 2221, when the user pushes the oil cup assembly 3 upward and resets the push rod 22, when the hook 24 is hooked in the limit groove 2221, the user will be given a force feedback, that is, the user can feel that the hook 24 is hooked in the limit groove 2221, so as to prevent the user from pushing the oil cup assembly 3 too far, so that the hook 24 is not left by the limit block 222.

[0039] See also Figures 3 to 10 In the range hood with a hidden oil cup of the utility model, the limit block 222 divides the slide 221 into a left part and a right part. A first limit surface 2211 is provided on the right side of the outlet end of the slide 221, and a second limit surface 2212 is provided on the right side of the bottom of the slide 221. When the driving end of the telescopic component 2 is in a retracted state, after the push rod 22 is pushed upward, the hook 24 disengages from the limit block 222 and exits the slide along the right part of the slide 221, and the compression spring 23 resets and pushes the push rod 22 downward; when the driving end of the telescopic component 2 is in an extended state, after the push rod 22 is pushed upward, the push rod 22 moves upward and compresses the compression spring 23, and at the outlet end of the slide 221, the hook 24 enters from the left part of the slide 221 until it is hooked on the limit block 222. When the driving end of the telescopic assembly 2 is in a retracted state, the hook 24 is hooked to the limit groove 2221 of the limit block 222. When the oil cup assembly 3 needs to be extended, the oil cup assembly 3 is pushed upward. When the oil cup assembly 3 applies an upward force to the push rod 22, the push rod 22 slides upward, and the bottom of the slide groove 221 moves upward relative to the hook 24. Due to the limitation of the second limit surface 2212, the push rod 22 cannot continue to move upward. The user removes the upward pushing force on the oil cup assembly 3. At this time, the compression spring 23 begins to reset, and the compression spring 23 pushes the push rod 22 downward. The hook 24 enters the right part of the slide groove 221 and slides out from the After the right side part of the groove 221 slides out and the compression spring 23 is fully reset, the oil cup assembly 3 extends from under the back plate 11; after the oil cup assembly 3 is cleaned, the oil cup assembly 3 is connected to the lower end of the push rod 22. At this time, when the driving end of the telescopic assembly 2 is in an extended state, the oil cup assembly 3 is pushed upward. When the oil cup assembly 3 applies an upward force to the push rod 22, the push rod 22 moves upward and compresses the compression spring 23. When the outlet end of the slide groove 221 rises to the hook 24, due to the limitation of the first limit surface 2211, the hook 24 enters from the left side of the slide groove 221 until it is hooked on the limit block 222.

[0040] See also Figure 1 and Figure 2 In the utility model of the range hood with hidden oil cup, the oil cup assembly 3 includes an oil cup 31 and a lifting frame 32. The lifting frame 32 is provided with an oil cup hanging ear 321. The oil cup 31 is provided with an oil cup hanging ear 321. The oil cup hanging ear 311 corresponding to the oil cup hanging ear 321 is clamped in the oil cup 31. The driving end of the telescopic assembly 2 is connected to the lifting frame 32. When the telescopic assembly 2 switches between the retracted state and the extended state, the telescopic assembly 2 drives the lifting frame 32 to rise and fall, and the oil cup 31 rises and falls with the lifting frame 32.

[0041] See also Figure 1 and Figure 2 The utility model of the range hood with hidden oil cup, the range hood body 1 also includes a back plate frame 12, the back plate frame 12 has an oil collecting chamber, the back plate 11 is connected to the front side of the back plate frame 12, the bottom of the back plate frame 12 has a receiving groove a for receiving the oil cup 31 and avoidance positions b located on both sides of the receiving groove a, the telescopic assembly 2 is installed on the back plate 11 and the avoidance position b is aligned, the driving end of the telescopic assembly 2 extends into the receiving groove a and is connected to the lifting frame 32. The telescopic assembly 2 is connected to the rear of the back plate 11 and the part aligned with the avoidance position b, the driving end of the telescopic assembly 2 extends into the receiving groove a and is connected to the lifting frame 32, and the oil cup 31 is connected to the bottom of the lifting frame 32. When the telescopic assembly 2 is in the retracted state, the oil cup 31 is located in the receiving groove a and hidden behind the back plate 11; when the push rod assembly 2 is in the extended state, the oil cup 31 is pushed downward and leaves the receiving groove a.

[0042] See also Figure 1 and Figure 2 In the range hood with a hidden oil cup of the present invention, a guide rail assembly 4 is provided on the side wall of the receiving groove a. The guide rail 41 of the guide rail assembly 4 is connected to the side wall of the receiving groove a. The slider 42 of the guide rail assembly 4 is slidably connected to the guide rail 41 and connected to the lifting frame 32. When the telescopic assembly 2 drives the lifting frame 32 to rise and fall, the slider 42 rises and falls with the lifting frame 32 and slides along the guide rail 41. The guide rail assembly 4 can make the lifting frame 32 move smoothly and make the two sides of the lifting frame 32 move synchronously, so as to prevent the oil cup 31 from tilting and interfering with the wall of the receiving groove a when entering or exiting the receiving groove a.

[0043] See also Fig.11The range hood with a hidden oil cup of the present invention further comprises a support assembly 5. When the driving end of the telescopic assembly 2 is in a retracted state, the support assembly 5 supports the oil cup assembly 3 from both sides of the oil cup assembly 3. After the range hood has worked for many times, the amount of oil in the oil cup 31 increases, and the weight of the oil cup 31 increases. At this time, the force applied by the oil cup 31 to the push rod 22 through the lifting frame 32 increases, and the force applied by the hook 24 to the limit groove 2221 of the limit block 222 increases. If the hook 24 and the limit block 222 cooperate to bear the weight, after long-term use, the hook 24 is at risk of deformation, and the limit block 222 is also at risk of deformation. When one of the hook 24 and the limit block 222 is deformed, the connection between the hook 24 and the limit block 222 will fail, so that the oil cup 31 cannot be retracted to the rear of the back plate 11. A support assembly 5 is set. After the oil cup 31 is retracted to the rear of the back plate 11, the load-bearing assembly 5 supports the oil cup assembly 3 from both sides of the oil cup assembly 3, which can extend the service life of the telescopic assembly 2.

[0044] See also Fig.11 In the range hood with a hidden oil cup of the utility model, the support assembly 5 includes a marble 51 and a spring 52. A mounting channel is provided on the slider 42. The marble 51 is installed in the mounting channel, and the spring 52 is squeezed in the mounting channel by the marble 51. A support groove 411 is provided on the upper end surface of the guide rail 41. When the driving end of the telescopic assembly 2 is in a retracted state, the marble 51 is inserted into the support groove 411. When the telescopic component 2 is in the retracted state, the marble 51 is aligned with the support groove 411. Under the action of the spring 52, the marble 51 extends out of the installation channel and enters the support groove 411. The downward pulling force of the oil cup 31 on the lifting frame 32 makes the slider 42 installed on the lifting frame 32 have a downward movement trend and acts on the marble 51 through the support groove 411. At this time, the marble 51 has an upward supporting force on the lifting frame 32 through the slider 42. The supporting force is recorded as F1. F1 is the force shared by the support component 5 on the telescopic component 2, which can reduce the downward pulling force of the lifting frame 32 on the push rod 22, and then reduce the action force between the hook 24 and the limit block 222, which can protect the hook 24 and the limit block 222 and extend the service life of the telescopic component 2.

[0045] See also Figure 1 and Figure 2The utility model has a range hood with a hidden oil cup, and the range hood body 1 also includes an air collecting box 13. The bottom of the air collecting box 13 is provided with an oil leakage hole aligned with the opening of the lifting frame 32, and the bottom of the lifting frame 32 is provided with an oil outlet hole aligned with the oil cup 31. When the range hood is working, the smoke exhaust fan in the air collecting box 13 is started, and the oil smoke enters the air collecting box 13 and is discharged by the smoke exhaust fan. In the process of the smoke exhaust fan discharging the oil smoke, oil will be generated on the inner wall surface of the air collecting box 13, and oil will also be generated on the volute and impeller of the smoke exhaust fan. The oil flows into the bottom of the air collecting box, and then drips into the lifting frame 32 through the oil leakage hole, and then drips into the oil cup 31 through the oil outlet hole at the bottom of the lifting frame 32, so that the oil in the oil cup 31 continues to increase; after the range hood has been used for a period of time, the oil will be discharged by the user. The user can apply force upward to the oil cup 31 to make the hook 24 leave the limit block 222, the compression spring 23 resets and pushes the push rod 22 to move downward, the push rod 22 pushes the lifting frame 32 downward and makes the oil cup 31 extend downward, so that the user can remove the oil cup 31 from the lifting frame 32 and clean the oil cup 31 conveniently; after the oil cup 31 is cleaned, the user connects the oil cup 31 to the lifting frame 32 again, and then pushes the oil cup 31 upward, so that the lifting frame 32 pushes the push rod 22 upward, and finally the hook 24 is connected to the limit block 222.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
