[0036] 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:
[0037] See also Figures 1 to 6 The utility model provides a range hood, including a range hood body 1, a box body 2 and a wireless connection module 3.
[0038] The range hood body 1 comprises a sheet metal housing 11, which defines an air intake 111. This housing 11 also includes a sheet metal cover 112, which defines a mounting opening 113 located at the top of the cover 112. In this embodiment, the housing 11 is constructed of sheet metal. The air intake 111 allows the user to activate the range hood, generating negative pressure in the air intake 111. This draws fumes into the housing 11 before exhausting them to the outside.
[0039] The box body 2 is located within the sheet metal housing 11 and is detachably connected to the sheet metal housing 11. The top of the box body 2 is embedded in the mounting opening 113. Specifically, the box body 2 is made of a plastic polymer material, i.e., the box body 2 is a plastic box body 2. In this embodiment, the box body 2 and the sheet metal housing 11 are fixedly connected by screws, so that the box body 2 can be more stably mounted on the sheet metal housing 11.
[0040] The wireless connection module 3 is removably mounted within the housing 2, and signals transmitted by the wireless connection module 3 can pass through the housing 2. The wireless connection module 3 includes at least one of a Bluetooth module and a WiFi module. In this embodiment, the wireless connection module 3 includes both a Bluetooth module and a WiFi module. In this embodiment, the user installs the wireless connection module 3 within the housing 2 using screws, thereby achieving quick installation of the wireless connection module 3.
[0041] When a user of the present invention uses the range hood, negative pressure is generated at the air intake 111, causing the oil smoke to enter the sheet metal shell 11 and then be discharged to the outside, thereby exhausting the oil smoke from the kitchen to the outside. At the same time, the wireless connection module 3 is installed in the box body 2, and the top of the box body 2 is embedded in the installation port 113. When the user needs to understand or control the range hood, the wireless connection module 3 transmits the signal through the box body 2, thereby connecting the user terminal to the wireless connection module 3. The sheet metal shell 11 cannot shield the transmission signal between the wireless connection module 3 and the user terminal, thereby enabling the signal transmitted by the wireless connection module 3 to better interact with the user terminal, improving the connection signal between the user terminal and the wireless connection module 3, and facilitating better signal transmission.
[0042] Based on the above examples, please refer to Figure 6 In this embodiment, the wireless connection module 3 includes an integrated circuit board 31 and a communication antenna 32. The integrated circuit board 31 includes a PCB board and a Bluetooth module chip and a WiFi module chip integrated thereon. Both the Bluetooth module chip and the WiFi module chip are communicatively connected to the communication antenna 32, enabling communication between the client terminal and the Bluetooth module chip and the WiFi module chip via the communication antenna 32.
[0043] The communication antenna 32 is detachably mounted on top of the integrated circuit board 31 and is electrically connected to the integrated circuit board 31. The communication antenna 32 is mounted on top of the integrated circuit board 31 by welding. Signals transmitted by the communication antenna 32 pass through the box body 2 and the mounting opening 113, preventing the sheet metal cover 112 from shielding the wireless connection module 3. This ensures a normal signal connection between the user terminal and the wireless connection module 3, thereby facilitating data transmission between the user terminal and the integrated circuit board 31 via the communication antenna 32.
[0044] Based on the above examples, please refer to Figure 5 and Figure 6 In this embodiment, the box body 2 includes an upper cover 21 and a base 22. The upper cover 21 is embedded in the mounting opening 113. The upper cover 21 and the base 22 are of the same size. A cavity is defined between the upper cover 21 and the base 22. The wireless connection module 3 is detachably mounted in the cavity. In this embodiment, the upper cover 21 and the sheet metal cover 112 have an interference fit, and the cavity is sealed. When the user installs the box body 2, the wireless connection module 3 is installed in the cavity, and then the upper cover 21 and the base 22 are buckled together to install the wireless connection module 3 in the box body 2, thereby preventing oil smoke from entering the cavity of the box body 2 and interfering with the wireless connection module 3; then, the upper cover 21 is embedded and installed in the installation opening 113, so that the upper cover 21 and the sheet metal cover 112 have an interference fit, so that the box body 2 can be better fixed on the sheet metal cover 112, thereby facilitating data transmission between the user terminal and the wireless connection module 3.
[0045] Based on the above examples, please refer to Figure 5 and Figure 6 In this embodiment, the cavity comprises an upper cavity and a lower cavity. The upper cavity is defined at the end of the upper cover 21 facing the base 22, while the lower cavity is defined at the end of the base 22 facing the upper cover 21. The wireless connection module 3 is removably mounted in the lower cavity. The volume of the lower cavity is 1.5 to 3.5 times that of the upper cavity. Specifically, the upper cavity is defined at the lower end surface of the upper cover 21, while the lower cavity is defined at the upper end surface of the base 22. In this embodiment, the volume of the lower cavity is 1.5 times that of the upper cavity; similarly, the volume of the lower cavity can also be set to 2 or 3.5 times that of the upper cavity. When the user installs the wireless connection module 3 in the lower cavity, the lower cavity not only facilitates installation of the wireless connection module 3, but also provides a gap between the top of the wireless connection module 3 and the top of the upper cover 21, and between the bottom of the wireless connection module 3 and the bottom of the lower cavity, facilitating heat dissipation for the wireless connection module 3.
[0046] Based on the above examples, please refer to Figure 5 and Figure 6 In this embodiment, the base 22 is provided with a fixing portion 221. When the upper cover 21 is embedded in the installation opening 113, the fixing portion 221 is tightly attached to the sheet metal cover 112 and is fixed to the sheet metal cover 112 via fasteners. When the box body 2 is installed, after the upper cover 21 is embedded in the installation opening 113, the fixing portion 221 is attached to the bottom end surface of the sheet metal cover 112 and is fixed to the sheet metal cover 112 via fasteners. This allows the box body 2 to be more stably fixed to the sheet metal cover 112, preventing the box body 2 from falling off the sheet metal cover 112.
[0047] Based on the above examples, please refer to Figure 5 and Figure 6 In this embodiment, the wireless connection module 3 also includes a power cord 33. A power hole 222 is defined in the side wall of the base 22. The power cord 33 passes through the hole 222 to electrically connect to the wireless connection module 3. In this embodiment, the hole 222 is a square hole, and the power cord 33 fits into the square hole, thereby preventing the inrush of oil smoke into the box body 2. During installation, the user passes the power cord 33 through the hole 222 to electrically connect to the wireless connection module 3. After the power cord 33 is connected to an external power source, the wireless connection module 3 is powered.
[0048] Based on the above examples, please refer to Figure 1 and Figure 3 In this embodiment, the fixing portion 221 is provided with a fixing hole, and the sheet metal cover 112 is provided with a screw hole 114. The screw hole 114 is located at the edge of the mounting opening 113 and is connected to the fixing hole. The screw hole 114 is provided with a countersunk platform so that after a screw adapted to the screw hole 114 is screwed into the countersunk platform, the screw cap can be flush with the sheet metal cover 112. In this embodiment, two screw holes 114 are provided on the left and right sides of the mounting opening 113, respectively, and each screw hole 114 is provided with a countersunk platform. Through the setting of the screw holes 114, the fixing holes and the sinking platform, during the installation process, the user embeds the upper cover 21 into the installation opening 113, and when the fixing part 221 is attached to the bottom end surface of the sheet metal cover 112, the screws are screwed into the screw holes 114 and the fixing holes in turn, and the screw caps of the screws are screwed into the sinking platform so that the screw caps are flush with the sheet metal cover 112, thereby not only quickly fixing the fixing part 221 to the sheet metal cover 112, but also making the screw caps flush with the sheet metal cover 112, making the appearance of the sheet metal cover 112 more beautiful.
[0049] Based on the above examples, please refer to Figure 1The present invention also includes a shielding film 4. The shielding film 4 is pasted on the top of the sheet metal cover 112, and the shielding film 4 can cover the screw holes 114 and the mounting port 113. The shielding film 4 can be a plastic film or a paper film. In this embodiment, the shielding film 4 is a plastic film made of plastic material. The user covers the screw holes 114 and the mounting port 113 with the shielding film 4 to prevent the screw holes 114 and the mounting port 113 from being exposed to the outside, thereby making the top of the sheet metal cover 112 more beautiful. At the same time, it also prevents oil stains from flowing to the screw holes 114 and the mounting port 113, thereby preventing oil smoke from invading the box body 2.
[0050] Building on the above embodiment, this embodiment comprises two sheet metal covers 112, which are positioned opposite each other on the top of the sheet metal housing 11. In this embodiment, the two sheet metal covers 112 are positioned opposite each other, one on the left and one on the right side of the top of the sheet metal housing 11. An opening is defined between the two covers 112 to facilitate installation of the range hood's air duct assembly. Furthermore, the presence of two sheet metal covers 112 facilitates removal during range hood repair or maintenance.
[0051] Based on the above examples, please refer to Figure 2 and Figure 4 The utility model also includes a side baffle assembly 5 and an oil cup 6.
[0052] Two side baffle assemblies 5 are provided, each detachably connected to the sheet metal housing 11 and located on the left and right sides of the air intake 111. In this embodiment, the side baffle assemblies 5 are glass baffles. During installation, the user installs the two side baffle assemblies 5 on the left and right sides of the sheet metal housing 11. When the user uses the range hood, negative pressure is generated at the air intake 111, causing oil smoke to be drawn into the air intake 111. The glass baffles block the oil smoke, concentrating it and reducing its escape from the left and right sides of the sheet metal housing 11.
[0053] The oil cup 6 is located at the bottom of the sheet metal housing 11 and is detachably connected to the housing 11. In this embodiment, the oil cup 6 is made of a high-temperature-resistant plastic cup. When the user uses the range hood, oil smoke enters the range hood body 1 through the air intake 111. After the oil smoke in the range hood body 1 cools, oil drips from the range hood body 1 into the oil cup 6. The oil cup 6 collects the oil to prevent it from dripping onto the kitchen stove. Furthermore, when the oil in the oil cup 6 reaches its maximum level or needs to be cleaned, the user removes the oil cup 6 from the bottom of the sheet metal housing 11 to clean the oil in the oil cup 6.
