Technical Field

[0001] The present invention relates to the technical field of range hoods, and particularly to a range hood with a mobile phone wireless charging function. Background Art

[0002] With the improvement of people's living standards, range hoods have become essential household appliances in families. It can be understood that range hoods can extract kitchen fumes to reduce the amount of fumes inhaled by users, improving the health of users. Generally, in order to facilitate users to cook in a relatively dark environment, range hoods are equipped with lighting lamps, and users can turn on the lighting lamps as needed.

[0003] In modern kitchen life, people frequently use mobile phones to consult recipes, answer calls, etc. However, traditional range hoods only focus on the fume extraction function. Mobile phone charging depends on an external charging cable and a socket. The oil stains and water stains in the kitchen environment are likely to contaminate the charging cable, and the messy wires affect the beauty and operation convenience of the kitchen. Existing wireless charging devices are mostly placed independently, and they need to occupy additional countertop space in the limited kitchen space, making them inconvenient to use.

[0004] Therefore, we introduce a range hood with a mobile phone wireless charging function. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1-7 Figures 1-7 For this invention, a technical solution is provided: a range hood with a mobile phone wireless charging function, including: a range hood housing 1, on the surface of the range hood housing 1 there is a range hood panel 6, and on the surface of the range hood panel 6 there is a control switch 7; A range hood filter screen 4, the range hood filter screen 4 is arranged at the bottom of the range hood housing 1, and on both sides of the bottom of the range hood housing 1 there are respectively arranged lighting lamps 5; A wireless mobile phone charging module 9, the wireless mobile phone charging module 9 is arranged on the surface of the range hood panel 6 on one side of the control switch 7, and the wireless mobile phone charging module 9 is used to fix the mobile phone for charging.

[0019]

[0019] The wireless mobile phone charging module 9 includes a wireless mobile phone charging module box 91, on one side of the wireless mobile phone charging module box 91 there is connected a magnet 96, the magnet 96 is used to adsorb the mobile phone with a magnet 96 for charging, on one side of the wireless mobile phone charging module box 91 on the side of the magnet 96 there is connected a wireless mobile phone charger 95 (the wireless mobile phone charger 95 is a power management chip, control unit), and on the side of the wireless mobile phone charging module box 91 there is connected a bottom frame 93.

[0020]

[0020] On the surface of the bottom frame 93 there are equidistantly connected buckles 94, and when the buckles 94 are snapped into the inside of the wireless mobile phone charging module box 91, the bottom frame 93 can fix the wireless mobile phone charger 95 and the magnet 96 together.

[0021]

[0021] On the surface of the wireless mobile phone charging module box 91 there is an empty slot 97 for placing the magnet 96.

[0022] On the surface of the range hood panel 6 there is an installation slot 92 for placing the wireless mobile phone charging module 9, and the installation slot 92 and the range hood panel 6 are integrally formed, which is convenient for installing the wireless mobile phone charging module 9.

[0023]

[0023] On the surface of the range hood panel 6 on the other side of the control switch 7 there is connected an NFC induction part 8, and the NFC induction part 8 reads various data of the range hood (real-time air volume / power, total usage duration and total power, range hood filter screen 4 cleaning reminder, etc.).

[0024]

[0024] On the top of the range hood housing 1 there is an air outlet 2, and the air outlet 2 is convenient for discharging the fumes to the outside.

[0025] Inside the range hood housing 1, a blower 3 is provided. The blower 3 is located at the bottom of the air outlet 2. After starting the range hood, the blower 3 starts to operate. The operation of the blower 3 generates a strong suction force, creating a negative pressure environment in the bottom area of the range hood. Under the action of the negative pressure, the cooking fumes generated in the kitchen are sucked into the range hood. The range hood filter screen 4 preliminarily filters the cooking fumes, intercepting large particulate oils and impurities in the cooking fumes to prevent them from entering the interior of the range hood and protecting components such as the blower 3. The filtered cooking fumes are discharged to the outside through the air outlet 2, thus achieving the purification of the kitchen air.

[0026] Specifically, during use, the core working system of this range hood covers two major functions: kitchen fume treatment and mobile phone wireless charging. The range hood generates suction through the operation of the blower 3, filters the cooking fumes in the kitchen through the range hood filter screen 4, and discharges them from the air outlet 2 to complete the basic fume purification work. At the same time, the wireless mobile phone charging module 9 provided on the range hood panel 6 realizes the wireless charging function with the mobile phone, and the NFC sensing part 8 provides convenient interaction possibilities for users. When a mobile phone that supports the wireless charging function and can be adsorbed and fixed by the magnet 96 is placed in the specific area where the wireless mobile phone charging module 9 is located on the range hood panel 6, the wireless charging receiving coil in the mobile phone and the charging coil in the wireless mobile phone charger 95 in the range hood enter the magnetic field induction coupling range. The magnet 96 on one side of the wireless mobile phone charging module box 91 plays a role in adsorbing the mobile phone, making it stably placed in the charging area, ensuring the stable relative position between the two coils, and providing a basis for efficient wireless charging. After the range hood is powered on, the power management chip delivers the electric energy converted from the range hood power supply to the charging coil of the wireless mobile phone charger 95. The charging coil generates an alternating magnetic field under the action of the electric energy. This alternating magnetic field will continuously change its direction and intensity with the change of the current in the charging coil. The wireless charging receiving coil of the mobile phone is in this alternating magnetic field. According to the principle of electromagnetic induction, when the receiving coil senses the change of the magnetic field, it will generate an electric current. The generated electric current is processed by the internal circuit of the mobile phone, such as a series of operations like rectification and voltage stabilization, and then charges the mobile phone battery, thus realizing the process of wireless charging. A control unit (i.e., the wireless mobile phone charger 95) is provided inside the range hood. It real-time monitors the battery power and charging status of the mobile phone. When the mobile phone battery reaches the full charge state, the control unit will automatically cut off the power supply of the wireless mobile phone charger 95 and stop charging to avoid overcharging the mobile phone and protecting the life and safety of the mobile phone battery. If the mobile phone is removed during the charging process, the control unit will also detect the change in the charging status and immediately cut off the charging function to prevent the waste of electric energy and achieve the purpose of energy conservation.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
