[0053] Example 1

[0054] like Figure 1 As shown, this disclosure provides an oil fume treatment device 100, and takes a top-mounted range hood as an example to illustrate the structure of the oil fume treatment device 100.

[0055] like Figure 1 As shown, the fume treatment device 100 includes a fan assembly 20, a fume collection system 10, and a pipe assembly 30. One end of the pipe assembly 30 is connected to the fan assembly 20, and the other end of the pipe assembly 30 is connected to the fume collection system 10. The fan assembly 20 can generate negative pressure, which allows the fumes from the cooking area 400 to pass through the fume collection system 10, the pipe assembly 30, and the fan assembly 20 in sequence before being discharged outdoors.

[0056] like Figure 1 As shown, the fan assembly 20 is installed above the ceiling 300, far from the user. The ceiling 300 can isolate the noise generated during the operation of the fan assembly 20, reducing the impact of noise on the user and improving the user experience. When the height of the wall 200 is different, the length of the pipe assembly 30 can be adjusted to ensure the reliability of the fume treatment device 100.

[0057] like Figure 1 As shown, the smoke collection system 10 includes a smoke collection chamber 11 and a flap 12. The smoke collection chamber 11 has a smoke inlet 111, and the flap 12 is disposed on the smoke collection chamber 11. The flap 12 can switch between a first state with the smoke inlet 111 open and a second state with the smoke inlet 111 closed.

[0058] Currently, the visualization of the fume treatment device 100 is mainly on the main control panel (not shown in the figure). In addition, the fume treatment device 100 will generate noise during use, and different parts of the fume treatment device 100 will generate different noise levels. However, the existing fume treatment device 100 has poor visualization of noise, and users cannot intuitively perceive the noise levels of different parts of the fume treatment device 100.

[0059] To solve the above problems, such as Figure 2 and Figure 3As shown, the fume treatment device 100 of this embodiment includes a sound detection device 40 and a projection component 50. The sound detection device 40 is used to obtain sound information at various locations of the fume treatment device 100. The projection component 50 includes a projection mechanism 51 and a display mechanism 52. The display mechanism 52 is disposed on the pipeline assembly 30. The projection mechanism 51 can project the distribution of sound information at various locations of the fume treatment device 100 onto the display mechanism 52, thereby enabling the display mechanism 52 to visualize the noise situation of various parts of the fume treatment device 100. Users can intuitively perceive the noise situation of various parts of the fume treatment device 100. In addition, the visualization of noise situation can make reasonable use of the large space of the existing pipeline assembly 30 of the fume treatment device 100 without making major modifications to the existing fume treatment device 100, which is conducive to the mass production of the fume treatment device 100 and effectively reduces the production cost of the fume treatment device 100.

[0060] It should be noted that, as Figure 2 and Figure 3 As shown, the sound detection device 40 can obtain the sound information of each position of the fume treatment device 100 and obtain the distribution of the sound information at each position of the fume treatment device 100 through algorithm fitting. The sound detection device 40 then transmits the distribution of each position of the fume treatment device 100 to the projection mechanism 51, and the projection mechanism 51 then projects the corresponding distribution onto the display mechanism 52.

[0061] For example, the core principle of converting sound information into an image is time-frequency analysis. The essence of sound information is a pressure wave that changes over time, while an image is two-dimensional static information (pixels). The key to converting sound information into an image lies in extracting the energy distribution information of the sound signal in both time and frequency dimensions. Specific algorithms can include short-time Fourier transform, continuous wavelet transform, discrete wavelet transform, Mel-frequency cepstral coefficient extraction, etc. Since algorithms for converting sound information into images are relatively conventional technologies in this field, this disclosure will not elaborate further. All methods capable of converting sound information into images are within the protection scope of this disclosure.

[0062] like Figure 2 and Figure 3 As shown, the sound detection device 40 includes a sound probe 41. The fan assembly 20, the pipeline assembly 30, and the smoke collection system 10 are all equipped with corresponding sound probes 41. The arrangement of multiple sound probes 41 enables the acquisition of sound information at various locations of the fume treatment device 100, and the distribution of sound information at various locations of the fume treatment device 100 can be obtained through algorithm fitting.

[0063] like Figure 3As shown, the position of the display mechanism 52 relative to the pipeline assembly 30 in the vertical direction is adjustable. The projection mechanism 51 includes a projection section 513, the position of which is adjustable in the vertical direction. By synchronously adjusting the position of the display mechanism 52 and the projection section 513 in the vertical direction, the distribution of sound information at various locations in the fume treatment device 100 in the vertical direction can be adjusted to meet the optimal viewing angle for users of different heights, thereby improving the user experience for different users.

[0064] For example, such as Figure 3 As shown, the projection mechanism 51 can be an LED projector, a laser projector, a hybrid HLD and LED light source projector, etc. All devices or structures capable of projection are within the protection scope of this disclosure.

[0065] For example, such as Figure 3 As shown, the display mechanism 52 can be a white plastic screen, a glass bead screen, a gray screen, an anti-glare screen, etc. All structures capable of projection reception and display are within the protection scope of this disclosure embodiment.

[0066] Specifically, such as Figure 3 and Figure 4 As shown, the fume treatment device 100 also includes a drive device 60. The drive device 60 includes a housing 61, a lead screw 62, a nut 63, and a rotary motor 65. The housing 61 is mounted on the pipe assembly 30. The lead screw 62 is rotatably connected to the housing 61 and extends vertically. The nut 63 is screwed onto the lead screw 62 and is fixedly connected to the display mechanism 52. The rotary motor 65 includes a body 651 and a rotating shaft 652 that can rotate relative to it. The rotating shaft 652 is fixedly connected to the lead screw 62. The body 651 drives the rotating shaft 652 to rotate, which in turn drives the lead screw 62 to rotate. The lead screw 62 drives the nut 63 to move vertically relative to the housing 61, thereby enabling the nut 63 to move the display mechanism 52 vertically, thus adjusting the position of the display mechanism 52 vertically. This type of drive device 60 has the advantages of high transmission efficiency, high precision, high rigidity, high load-bearing capacity, long service life, and good smoothness of movement. In addition, the drive device 60 can also be a linear motor, a linear cylinder, etc. All drive structures capable of achieving linear output are within the protection scope of the embodiments of this disclosure.

[0067] like Figure 3As shown, the display mechanism 52 includes a display body 521 and a connecting part 522. The display body 521 is located on the front side of the pipeline assembly 30. Connecting parts 522 are provided on both sides of the display body 521 in the width direction. Each connecting part 522 is provided with a corresponding drive device 60. The connecting part 522 is fixedly connected to the corresponding nut 63. By providing connecting parts 522 on both sides of the display mechanism 52, a stable connection between the display mechanism 52 and the drive device 60 can be achieved, and the left and right tilting of the display mechanism 52 during the lifting process can also be avoided.

[0068] like Figure 3 As shown, the projection mechanism 51 also includes a mounting part 511 and a first lifting mechanism 512. The mounting part 511 is fixedly connected to the position to be installed. One end of the first lifting mechanism 512 is fixedly connected to the mounting part 511, and the other end of the first lifting mechanism 512 is fixedly connected to the projection part 513. The position of the projection part 513 can be adjusted in the vertical direction by the lifting action of the first lifting mechanism 512.

[0069] For example, such as Figure 3 As shown, the first lifting mechanism 512 can be a linear motor, a hydraulic lifting structure, a pneumatic lifting structure, a lead screw and nut structure, etc. All structures that can achieve linear output are within the protection scope of this disclosure embodiment.

[0070] like Figure 3 As shown, the projection mechanism 51 also includes a sealing plate 514, which is disposed at the lower end of the projection part 513. When the first lifting mechanism 512 is in the retracted state, the first lifting mechanism 512 can make the sealing plate 514 seal the opening of the ceiling (not shown in the figure). When the projection mechanism 51 is in the non-working state, it can ensure the sealing and aesthetics of the ceiling (not shown in the figure).

[0071] like Figure 3 As shown, the projection mechanism 51 also includes a sound mechanism 516, which is connected to the projection mechanism 51. The sound mechanism 516 can play sounds, such as music, radio dramas, crosstalk, skits, and the working status of the fume treatment device 100, which can increase the user's entertainment and user experience during use.

[0072] like Figure 3 As shown, sound mechanisms 516 are provided on both sides of the projection mechanism 51, thereby achieving stereo sound effects. In addition, whether the user is cooking on the left or right stove, they can receive the sound played by the sound mechanism 516 well.

[0073] like Figure 5As shown, the graphics projected by the projection mechanism 51 onto the display mechanism 52 can be a music image 70, a reference image 80, and a noise distribution image 90. The music image 70 contains information related to the sound played by the sound mechanism 516. The reference image 80 and the noise distribution image 90 are used together. The noise distribution image 90 is a gradient cloud map, representing the outer contour of the fume treatment device 100. Different colors are displayed at different locations on this outline to indicate different noise intensities. The reference image 80 is a coordinate scale, where different colors correspond to different noise intensity values.

[0074] Example 2

[0075] like Figure 6 As shown, this embodiment of the present disclosure provides an oil fume treatment device 100. The structure of the oil fume treatment device 100 is basically the same as that of the oil fume treatment device 100 in Embodiment 1. The main difference between the two is that the projection mechanism 51 is set in a different position. The projection mechanism 51 also includes a second lifting mechanism 515. One end of the second lifting mechanism 515 is fixedly connected to the smoke collection system 10, and the other end of the second lifting mechanism 515 is fixedly connected to the projection part 513. This kind of oil fume treatment device 100 has a more compact overall structure, does not require additional kitchen space, and is easy to install.

[0076] For example, such as Figure 6 As shown, the second lifting mechanism 515 can be a linear motor, a hydraulic lifting structure, a pneumatic lifting structure, a lead screw and nut structure, etc. All structures that can achieve linear output are within the protection scope of this disclosure embodiment.

[0077] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
