Description

Technical Field

[0001] This utility model relates to the technical field of television back panels, and in particular to a dustproof television back panel. Background Technology

[0002] Televisions typically have numerous ventilation grilles on their back panels to dissipate heat during operation. These grille-style vents are simple in structure but require a large number of grilles to achieve effective heat dissipation.

[0003] A known Chinese patent, authorized publication number CN221127363U, describes a TV back panel with a dustproof structure. It uses a dustproof mesh design to prevent dust from entering the TV's interior while ensuring the TV's internal ventilation. The heat dissipation holes at the bottom also reduce the amount of dust entering the TV's interior.

[0004] However, in actual use, because the heat dissipation holes are located at the bottom, dust from the ground can more easily enter the TV from the bottom. The dust filter structure is not only not very effective at preventing dust, but it can also easily become clogged with dust if not cleaned in time. Furthermore, the single-channel heat dissipation vent at the bottom does not allow for smooth airflow inside the TV, and the heat generated by the electronic components is more likely to accumulate in the middle of the back panel, making it difficult for the heat to dissipate. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a dustproof television back panel.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A dustproof television back panel includes: a television back panel, both sides of which have heat dissipation vents, and dustproof devices are installed on the heat dissipation vents. The dustproof device on the left side of the television back panel includes a first dustproof frame, on which a dust collection box is installed via a frame. The dustproof device on the right side of the television back panel includes a second dustproof frame, and a dust collection bag is adhered inside the second dustproof frame.

[0008] Furthermore, the first dustproof rack has a wide opening on the front and a narrow opening on the back.

[0009] Furthermore, the wide opening on the front of the first dustproof frame is connected to the dust collection box, and an exhaust box is installed on the narrow opening on the back of the first dustproof frame. The exhaust box has a ladder structure, and an exhaust groove is opened on the outside of the exhaust box. The exhaust groove is the same size as the narrow opening.

[0010] Furthermore, the dust collection box has a tiered structure, and a back plate is installed on the contact surface between the dust collection box and the first dustproof frame. Multiple small holes are evenly opened on the back plate, and a panel is installed on the side of the dust collection box away from the first dustproof frame. Multiple large holes are evenly opened on the panel.

[0011] Furthermore, a dust collection box is installed at the bottom of the dust collection box, and a rubber ring is installed at the top of the dust collection box.

[0012] Furthermore, both sides of the first and second dustproof frames are equipped with support portions, and a support frame is installed inside the support portion. The support frame includes a connecting plate, and one side of the connecting plate is fixed with a side plate by a toothed plate. The toothed plate is filled with soft strips.

[0013] Furthermore, the second dustproof frame has narrow openings of equal width on both sides, and the two narrow openings are connected by a dust collection bag.

[0014] Furthermore, exhaust boxes are installed on both sides of the second dustproof frame, and the two exhaust boxes are connected to the narrow opening of the second dustproof frame.

[0015] Compared with the prior art, the present invention has at least the following advantages:

[0016] This utility model's dustproof TV back panel, through the design of heat dissipation vents on both sides of the TV back panel, prevents ground dust from directly contacting the vents. Furthermore, because the vents are designed on both sides of the TV back panel, air can circulate from one side to the other, improving heat dissipation. The structural design of the first and second dustproof frames allows dust to be intercepted and collected, thus preventing the vents from becoming clogged due to prolonged lack of cleaning.

[0030] Please see Figure 1-5 A dustproof television back panel includes: a television back panel 1, with heat dissipation vents 2 on both sides of the television back panel 1, and a dustproof device 3 installed on the heat dissipation vents 2. The dustproof device 3 on the left side of the television back panel 1 includes a first dustproof frame 31, and a dust collection box 32 is installed on the first dustproof frame 31 via a box frame 33. The dustproof device 3 on the right side of the television back panel 1 includes a second dustproof frame 315, and a dust collection bag 314 is glued inside the second dustproof frame 315.

[0031] The dustproof TV back panel 1 of this utility model has heat dissipation vents 2 on both sides of the TV back panel 1, which prevents ground dust from directly contacting the heat dissipation vents 2. Furthermore, due to the design on both sides of the TV back panel 1, air can circulate from one side to the other, thus improving the heat dissipation effect. Relying on the structural design of the first dustproof frame 31 and the second dustproof frame 315, dust can be intercepted and collected, thereby avoiding the blockage of the heat dissipation vents 2 due to long-term uncleaning.

[0032] Please see Figure 3 The first dustproof bracket 31 has a wide opening on the front and a narrow opening on the back. The wide opening on the front of the first dustproof bracket 31 is connected to the dust collection box 32. An exhaust box 34 is installed on the narrow opening on the back of the first dustproof bracket 31. The exhaust box 34 has a trapezoidal structure. An exhaust groove 35 is opened on the outside of the exhaust box 34. The exhaust groove 35 is the same size as the narrow opening. Due to the outer wide and inner narrow structure design, the air blowing through the first dustproof bracket 31 is compressed, thereby accelerating the air flow and allowing the heat inside the television to be carried out by the air.

[0033] Please see Figure 4 The dust collection box 32 has a ladder structure. A back plate 312 is installed on the contact surface between the dust collection box 32 and the first dustproof frame 31. Multiple small holes 313 are evenly opened on the back plate 312. A panel 38 is installed on the side of the dust collection box 32 away from the first dustproof frame 31. Multiple large holes 39 are evenly opened on the panel 38. The design of the panel 38 and the back plate 312 makes it easy to intercept and collect dust inside the dust collection box 32. In conjunction with the ash box 310 at the bottom of the dust collection box 32, it is easy to collect dust again and avoid dust scattering. The ash box 310 is installed at the bottom of the dust collection box 32, and a rubber ring 311 is installed on the top of the ash box 310.

[0034] Please see Figure 3-6 Both sides of the first dustproof frame 31 and the second dustproof frame 315 are equipped with a support 37. A support frame 36 is installed inside the support 37. The support frame 36 includes a connecting plate 364. One side of the connecting plate 364 is fixed with a side plate 362 by a toothed plate 361. The toothed plate 361 is filled with a soft strip 363. With the support frame 36, the entire dustproof device 3 can be easily inserted into the heat dissipation port 2. Due to the soft strip 363 filled in the toothed plate 361, the toothed plate 361 generates friction with the support 37 and with the heat dissipation port 2, making the connection between the entire dustproof device 3 and the heat dissipation port 2 more stable.

[0035] Please see Figure 5 The second dustproof frame 315 has narrow openings of equal width on both sides, and the two narrow openings are connected by a dust collection bag 314. Both sides of the second dustproof frame 315 are equipped with exhaust boxes 34, and the two exhaust boxes 34 are connected to the narrow openings of the second dustproof frame 315. Relying on the dust collection bag 314 and the design of the second dustproof frame 315, cold air enters at the first dustproof frame 31, and then the cold air carries away the heat of the electronic components and is discharged from the second dustproof frame 315.

[0036] In use, the support frame 36 is pressed into the support 37 to retract the support frame 36, and then the dustproof device 3 is installed on the heat dissipation port 2 in sequence. Through different wide and narrow opening structure designs, the air entering the back panel 1 of the TV is compressed, thereby achieving rapid heat dissipation.

[0037] The structure of the flexible strip 363 is adopted. When the TV speaker vibrates, the flexible strip 363 shakes, thereby controlling the first dust cover 31 or the second dust cover 315 to shake off the dust inside. The dust falls into the corresponding storage slots, avoiding the need to repeatedly remove and remove the TV to clean the dust.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
