Specific embodiments

[0021] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The role of the drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be construed as a limitation on the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution: a range hood with a weighing sensor for cleaning reminder function, including a range hood body 1. A mesh cover 2 is fixedly installed at the bottom of the range hood body 1. An oil drip tray 3 is arranged at the bottom of the mesh cover 2 for receiving oil droplets. A mounting box 7 is fixedly connected to the bottom of the oil drip tray 3. A weighing sensor 10 is fixedly connected inside the mounting box 7. The surface of the weighing sensor 10 is fixedly connected to the inside of the oil drip tray 3, so as to monitor the weight of the oil droplets in the oil drip tray 3 through the weighing sensor 10. A warning lamp 8 is fixedly connected to the bottom of the mounting box 7. The warning lamp 8 is electrically connected to the weighing sensor 10. The weighing sensor 10 triggers the warning lamp 8, which facilitates the user to easily judge whether the oil droplets in the oil drip tray 3 need to be cleaned. At the same time, the setting of the mounting box 7 provides an installation space for the battery, thereby supplying power to the weighing sensor 10 and the warning lamp 8. The surface of the mounting box 7 is rotatably connected with a box cover 9, which is convenient for the user to replace the battery.

[0023] Further, a connecting sleeve 11 is provided at the upper end of the load cell 10. A screw rod 17 is fixedly connected to the bottom of the connecting sleeve 11. A fixing sleeve 20 is fixedly connected to the upper end of the load cell 10. The surface of the screw rod 17 is threadedly connected to the inner wall of the fixing sleeve 20 to connect the connecting sleeve 11 and the fixing sleeve 20. Two convex blocks 12 are fixedly connected to the inner wall of the connecting sleeve 11. A connecting column 4 is fixedly connected to the bottom of the wire mesh cover 2. The connecting column 4 matches the inner wall of the connecting sleeve 11. Two vertical grooves 5 are formed on the surface of the connecting column 4. Two arc grooves 6 are formed on the surface of the connecting column 4. The two arc grooves 6 are respectively communicated with the two vertical grooves 5. Thus, through the settings of the convex blocks 12, the vertical grooves 5 and the arc grooves 6, the user only needs to align the convex blocks 12 with the vertical grooves 5, then insert the convex blocks 12 into the vertical grooves 5, and rotate the oil receiving tray 3 to make the convex blocks 12 enter the arc grooves 6, then the oil receiving tray 3 can be installed at the bottom of the wire mesh cover 2, which facilitates the user to remove the oil receiving tray 3 and improves the convenience of the device during use.

[0024] A hemispherical first oil receiving film 13 is placed on the inner wall of the oil receiving tray 3. A third oil receiving film 19 with an arc-shaped cross-section is fixedly connected to the inner wall of the first oil receiving film 13. A second oil receiving film 18 in a conical shape is fixedly connected to the inner wall of the third oil receiving film 19. A support sleeve 21 is fixedly connected to the surface of the load cell 10. The support sleeve 21 is located outside the fixing sleeve 20. A conical extrusion sleeve 16 is fixedly connected to the surface of the connecting sleeve 11. The extrusion sleeve 16 corresponds to the support sleeve 21. One end of the second oil receiving film 18 away from the third oil receiving film 19 is located between the extrusion sleeve 16 and the support sleeve 21. Thus, when installing the second oil receiving film 18, the user only needs to put the second oil receiving film 18 on the support sleeve 21, and then install the connecting sleeve 11 on the fixing sleeve 20. Then, as the connecting sleeve 11 descends, the extrusion sleeve 16 contacts the support sleeve 21, and the second oil receiving film 18 is pressed between the extrusion sleeve 16 and the support sleeve 21, thereby realizing the installation of the second oil receiving film 18 and facilitating the use of the device.

[0025] Further, a connecting rod 14 is fixedly connected to the surface of the extrusion sleeve 16. One end of the connecting rod 14 away from the extrusion sleeve 16 is fixedly connected to a support ring 15. The surface of the support ring 15 contacts the inner wall of the first oil receiving film 13.

[0026] Specifically, when installing the first oil receiving film 13, the second oil receiving film 18 and the third oil receiving film 19, the third oil receiving film 19 is put on the supporting sleeve 21, and then the connecting sleeve 11 is installed on the fixing sleeve 20. Then, as the connecting sleeve 11 descends, the extrusion sleeve 16 presses the third oil receiving film 19 between the supporting sleeve 21 and the extrusion sleeve 16. At the same time, the descending of the extrusion sleeve 16 drives the support ring 15 to descend, and then cooperates with the inner wall of the oil receiving pan 3 to press the outer ring of the first oil receiving film 13 and fix the first oil receiving film 13 in the oil receiving pan 3, thereby preventing the first oil receiving film 13 from being affected by the dripping of oil droplets, causing the first oil receiving film 13 to be skewed relative to the inside of the oil receiving pan 3, affecting the first oil receiving film 13 from receiving oil droplets, thereby ensuring the normal use of the device.

[0027] Secondly, when the oil droplets are received, the oil droplets fall into the oil receiving pan 3 and drip onto the first oil receiving film 13 and the third oil receiving film 19. Then, the third oil receiving film 19 is subjected to the gravity of the oil droplets, and the wrinkles of the third oil receiving film 19 are flattened, so that the weight of the oil droplets can be monitored by the weighing sensor 10. Then, when there is a lot of oil in the oil receiving pan 3, the weighing sensor 10 triggers the prompt light 8, so that the prompt light 8 produces a bright light, reminding the user that the oil in the oil receiving pan 3 needs to be cleaned, so that the user can be judged based on the actual amount of grease accumulation to remind the user to clean the range hood, thereby improving the use effect of the device and improving the practicality of the device.

[0028] When the oil needs to be cleaned, the oil in the oil pan 3 can be directly dumped, and then the first oil receiving film 13, the third oil receiving film 19 and the second oil receiving film 18 can be replaced. During the whole process, the weighing sensor 10 is not in contact with the oil, thereby reducing the weighing sensor 10 from being soaked in oil for a long time, reducing the monitoring effect of the weighing sensor 10, and affecting the use of the weighing sensor 10, thereby improving the service life of the device and improving the use effect of the device.

[0029] Working principle: When the oil droplets are received, the oil droplets fall into the oil receiving pan 3, and drip onto the first oil receiving film 13 and the third oil receiving film 19. Then, the third oil receiving film 19 is affected by the gravity of the oil droplets, and the wrinkles of the third oil receiving film 19 are flattened, so that the weight of the oil droplets can be monitored by the weighing sensor 10. Then, when there is a lot of oil in the oil receiving pan 3, the weighing sensor 10 triggers the warning light 8, so that the warning light 8 produces light, reminding the user that the oil in the oil receiving pan 3 needs to be cleaned.

[0030] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
