[0023] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0024] Please refer to Figures 1-3 This embodiment provides a range hood 100, which includes a range hood body 110, a fan assembly 120, a smoke collection hood 130, a cleaning unit 140, and at least one oil cup 150. The fan assembly 120 is placed inside the main body 110 of the range hood; and in this embodiment, the smoke collection hood 130 is connected to the main body 110 of the range hood; the oil cup 150 is detachably connected to the smoke collection hood 130. The cleaning unit 140 is connected to the fume hood 130 or the oil cup 150 and is used to introduce cleaning material into the oil cup 150 or the fume hood 130.

[0025] Please refer to Figures 1-3 The working principle of this range hood 100 is as follows: The range hood 100 includes a main body 110, a fan assembly 120, a smoke collection hood 130, a cleaning unit 140, and at least one oil cup 150. The fan assembly 120 is placed inside the main body 110. The smoke collection hood 130 is connected to the main body 110. During operation, the range hood 100 draws in the smoke from the inlet of the smoke collection hood 130 through the operation of the fan assembly 120. When configuring the smoke inlet of the smoke collection hood 130, a movable flap 160 can be provided at the smoke inlet to open or close the smoke inlet. A display panel and an operation panel can be configured on the movable flap 160 for easy observation and use.

[0026] The oil cup 150 is detachably connected to the fume hood 130, which is intended to facilitate cleaning by removing the oil cup 150. The cleaning unit 140 is connected to the fume hood 130 or the oil cup 150 and is used to introduce cleaning materials into the oil cup 150 or the fume hood 130. It should be noted that the cleaning unit 140 contains solid or liquid cleaning materials, which are introduced into the oil cup 150 or the fume hood 130 to dissolve the oil stains in the oil cup 150, improve its fluidity or reduce its adhesion. In addition, the cleaning materials can also be used to sterilize the oil cup 150 and reduce the odor of the oil cup 150.

[0027] When discharging cleaning materials, the cleaning unit 140 can guide them into the fume hood 130 or into the oil cup 150 as needed. That is, it can directly guide the cleaning materials into the oil cup 150 to treat the existing oil stains in the oil cup 150, or it can guide them into the fume hood 130 so that when the oil fumes are drawn into the fume hood 130, they mix with the oil fumes drawn into the fume hood 130 to improve the fluidity of the oil fumes after liquefaction or reduce their viscosity, so that they can quickly collect into the oil cup 150. That is, it is convenient to treat the drawn oil fumes in the fume hood.

[0028] In summary, the range hood 100 has a simple structure and can introduce cleaning materials into the oil cup 150 or the smoke collection hood 130. The cleaning materials can dissolve the oil stains in the oil cup 150, improve its fluidity, or reduce its adhesion, thereby facilitating the pouring out of the oil stains and the cleaning of the oil cup 150. This simplifies the cleaning process, reduces the need for subsequent rinsing or wiping of the oil cup 150, and improves the cleaning efficiency of the oil cup 150.

[0029] Further, please refer to Figures 1-3 In this embodiment, when configuring the cleaning unit 140, the cleaning unit 140 may include a material container 141 and a discharge module 142, both of which are connected to the fume hood 130. The material container 141 is used to contain cleaning materials; the discharge module 142 is used to discharge the cleaning materials from the material container 141 and guide the discharged cleaning materials to be released into the oil cup 150 or the fume hood 130. The material container 141 is used to contain cleaning materials, while the discharge module 142 is used to discharge the cleaning materials into the oil cup 150 or the fume hood 130.

[0030] Depending on the type of cleaning material, the cleaning unit 140 can be configured to export solid materials or to export liquid materials. Furthermore, in this embodiment, when exporting liquid cleaning materials, the cleaning material can be exported in an atomized manner.

[0031] For liquid cleaning materials, the discharge module 142 includes a feeder 143 and a guide pipe 144. The inlet of the feeder 143 is connected to the material container 141, and the outlet of the feeder 143 is connected to the guide pipe 144. The feeder 143 is used to deliver the cleaning material in the material container 141 to the oil cup 150 or the fume hood 130 via the guide pipe 144. That is, when the cleaning material is liquid, it can be pumped out by a pump body. Therefore, the feeder 143 can be a guide pump and release it into the oil cup 150 or the fume hood 130. It should be noted that when pumping it to the fume hood 130, in order to improve the mixing effect with the oil fumes drawn into the fume hood 130, the cleaning material can be released into the fume hood 130 in an atomized manner.

[0032] Furthermore, in order to improve the treatment effect on the oil stains in the oil cup 150 when the cleaning material is released into the oil cup 150, the guide pipe 144 can be arranged along the length direction of the oil cup 150, and at least one first discharge port 145 and / or at least one second discharge port can be arranged at intervals along the length direction of the oil cup 150, and each oil cup 150 corresponds to at least one first discharge port 145; wherein, the first discharge port 145 can release the cleaning material toward the oil cup 150, and the second discharge port can release the cleaning material toward the fume hood 130.

[0033] That is, when the cleaning material is released into the oil cup 150 through the first discharge port 145, multiple first discharge ports 145 can be configured so that the cleaning material can be released at intervals along the length of the oil cup 150, thereby improving the cleaning efficiency of the cleaning material in treating oil stains; and when there are multiple oil cups 150, each oil cup 150 can have at least one corresponding first discharge port 145 to release cleaning material to it, so as to ensure the treatment effect of oil stains in the oil cup 150.

[0034] When releasing cleaning material into the fume hood 130 through the second discharge port, multiple second discharge ports can be configured so that the cleaning material can be released at intervals along the length of the oil cup 150, thereby improving the mixing effect of the cleaning material with the oil fumes drawn into the fume hood 130 and thus improving the oil stain treatment efficiency. In addition, in order to improve the treatment effect of oil stains in the oil cup 150 and the fume hood 130, the liquid cleaning material can be atomized and transported into the oil cup 150 or the fume hood 130. Therefore, an atomizing nozzle can be provided at the first discharge port 145 or the second discharge port.

[0035] For solid cleaning materials, they can be granular powder, flakes, or filaments. The specific form can be adjusted according to actual usage requirements. This embodiment takes solid cleaning materials in powder form as an example. Specifically, the discharge module 142 includes a feeding pipe, a feeding roller, and a drive motor. The feeding pipe is arranged along the length of the oil cup 150 and communicates with the material container 141. The feeding roller is rotatably connected inside the feeding pipe and is driven by the drive motor. The feeding pipe is equipped with at least one third discharge port, and each oil cup 150 corresponds to at least one third discharge port. The feeding roller is used to rotate under the drive of the drive motor, thereby conveying the cleaning material in the material container 141 to the oil cup 150 through the third discharge port. Therefore, through the above-described structural arrangement, the clean material in the material container 141 can be introduced into the feeding pipe and transported to the oil cup 150 by the rotation of the feeding roller. Moreover, when configuring the third discharge port, it can be adjusted according to the number of oil cups 150, so that each oil cup 150 corresponds to at least one third discharge port.

[0036] During the use of the range hood 100, the cleaning material in the material container 141 will be consumed over time. Therefore, the cleaning material needs to be replenished within a certain period of use. Based on this, in order to facilitate the replenishment of cleaning material into the material container 141, the material container 141 can be detachably connected to the smoke hood 130 or detachably connected to the oil cup 150, so that the cleaning material can be replenished inside by removing it.

[0037] Please refer to Figures 1-4 The following explanation uses the example of a detachable connection between the material container 141 and the fume hood 130: The smoke hood 130 is provided with a mounting position 131 for installing a material container 141, and a connector 132 for engaging with the material container 141 in the mounting position 131; a passage 133 is provided on one side of the smoke hood 130 in the area opposite the mounting position 131; wherein, the material container 141 is detachably connected to the mounting position 131 and can be moved into or out of the mounting position 131 through the passage 133.

[0038] Therefore, with this arrangement, the material container 141 can be inserted into the mounting position 131 through the port 133 and connected to the connector 132 inside the smoke hood 130, thereby maintaining its installation state in the mounting position 131; moreover, when configuring the mounting position 131, it can be an installation cavity communicating with the port 133, thereby improving the installation stability of the material container 141.

[0039] Based on the above, please refer to Figures 1-7When configuring the oil cup 150, multiple oil cups 150 can be set. The purpose is to reduce the length of a single oil cup 150 by setting multiple oil cups 150, so as to facilitate the disassembly, maintenance and cleaning of the oil cup 150. Based on this, taking the configuration of two oil cups 150 as an example, the range hood 100 includes two parallel oil cups 150. The adjacent ends of the two oil cups 150 abut against each other, and their abutting surfaces are respectively provided with positioning protrusions 151 and positioning grooves 152. The positioning protrusions 151 are used to cooperate with the positioning grooves 152. Therefore, by configuring a positioning groove 152 and a positioning protrusion 151 at the contact end of the two oil cups 150, the connection stability can be improved, thereby reducing the oil leakage at the connection of the oil cups 150. At the same time, an oil baffle 153 can be configured at the open end of the oil cup 150 to prevent oil leakage at the connection of the two oil cups 150.

[0040] Furthermore, both oil cups 150 are slidably connected to the smoke hood 130, which facilitates their installation and maintenance through the sliding connection. Additionally, the two oil cups 150 can slide out from one side of the smoke hood 130, or each oil cup 150 can slide out from one side of the smoke hood 130. Therefore, an opening can be provided on one side of the smoke hood 130 for the two oil cups 150 to slide in or out, i.e., the two oil cups 150 slide in or out from the same side of the smoke hood 130; or, openings can be provided on opposite sides of the smoke hood 130, with each opening allowing an adjacent oil cup 150 to slide in or out, i.e., the two oil cups 150 slide out from one side of the smoke hood 130 respectively.

[0041] Further, please refer to Figures 1-7 Based on the above structure, in order to detect the capacity of the cleaning material in the material container 141 so as to remind the user to replenish the material in time, the range hood 100 also includes a material detector 170 connected to the smoke collection hood 130. The material detector 170 is located on the side of the mounting position 131 away from the passage 133. The material detector 170 is used to detect the remaining amount of cleaning material in the material container 141.

[0042] Furthermore, to detect the amount of oil in the oil cup 150, the range hood 100 also includes an oil level detector 180. The oil level detector 180 is connected to the oil cup 150 or the smoke collection hood 130 and is used to detect the oil level in the oil cup 150; or, the oil cup 150 is equipped with an oil level display window that can display the oil level. It should be noted that when configuring the oil level detector 180 and the aforementioned material detector 170, they can be infrared liquid level detectors in the prior art, or other liquid level detection structures in the prior art. Their specific principles will not be elaborated here.

[0043] Therefore, by means of the above-described structural configuration, the time and amount of cleaning material introduced into the oil cup 150 by the oil level detection of the oil cup 150 can be determined; and based on the detection results of the material detector 170, the user can be reminded to replenish the cleaning material in a timely manner to ensure the normal use of the cleaning unit 140.

[0044] In summary, please refer to Figures 1-7 Based on the above, it can be seen that by adopting the structure of the cleaning unit 140, the range hood 100 can introduce cleaning material into the oil cup 150 or the smoke collection hood 130 in a timely manner according to the amount of oil in the oil cup 150 of the range hood 100, thereby cleaning the oil in the smoke collection hood 130 or the oil cup 150 in a timely manner. The cleaning methods include dissolving the oil stains in the oil cup 150, increasing its fluidity, or reducing its adhesion. In addition, it can also sterilize the oil cup 150 with cleaning materials to reduce the odor of the oil cup 150. In this way, the range hood 100 can self-clean the oil stains and reduce the steps and difficulty for users to clean the oil stains in the oil cup 150. This allows users to simply pour out the oil mixed with cleaning materials from the oil cup 150 and rinse it briefly to complete the cleaning process. This simplifies the cleaning steps, reduces the amount of time users need to spend cleaning the oil cup 150, and improves the ease of use of the range hood 100.

[0045] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
