Description

Technical Field

[0001] This utility model relates to the field of air purification technology, specifically to a carbon fiber filter winding tape. Background Technology

[0002] Formaldehyde, as a major pollutant, poses a serious threat to human health. Formaldehyde is a highly volatile organic compound (VOC), and long-term exposure can cause respiratory diseases, allergic reactions, and even increase the risk of cancer. Therefore, efficient and long-lasting formaldehyde removal technology has become a key research direction in the field of air purification.

[0003] Existing technologies for formaldehyde removal, such as mainstream particulate filters and photocatalytic / bioenzyme technologies, have limitations in performance. Activated carbon fiber, with its unique structural properties, solves the balance problem of adsorption efficiency, wind resistance control, and long-term stability. Activated carbon fiber can achieve an effective contact area of ​​over 95% and wind resistance of less than 15 Pa, and it does not cause secondary pollution during use. It exhibits unique advantages in fields with stringent air quality requirements, such as medical and food industries, laying the foundation for developing more efficient dynamic adsorption systems. In particular, its entangleable and foldable characteristics greatly expand its application possibilities in complex spaces. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the defects of the filter structure balance in the prior art, thereby providing a carbon fiber filter winding belt.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A carbon fiber filter winding tape includes a wrapping tape, a support frame, and a filter screen. The support frame and the filter screen are both installed inside the wrapping tape. The wrapping tape has sealing elements at both ends. The filter screen also has a heating element on the side away from the support frame. The heating element is also installed inside the wrapping tape and extends out of the sealing elements at both ends. The surface of the filter screen is also provided with support bones.

[0007] By adopting the above technical solution, the filter wrapping tape consists of a filter screen and a wrapping tape, and is supported by a support frame and support bones inside. It can be flexibly positioned as a flat filter tape or a wrapped filter tape, and can be adapted to different usage scenarios, making it highly practical. The addition of a heating element inside the wrapping tape, together with the sealing element and the electrical component, enables the internal product to be heated, which improves the formaldehyde decomposition catalytic effect and enhances the efficiency of formaldehyde removal.

[0008] Furthermore, the filter screen includes a filter layer, two antibacterial layers, and two functional layers. The top and bottom surfaces of the filter layer are covered with antibacterial layers. The functional layers are arrayed granular balls disposed between the filter layer and the antibacterial layers. The functional layers and the antibacterial layers are hot-pressed onto the filter layer.

[0009] By adopting the above technical solution, the filter layer is made of activated carbon fiber and modified to increase the formaldehyde capture and catalytic function of activated carbon fiber. Antibacterial layers are set on the upper and lower sides of the filter layer to reduce the influence of water vapor and humidity. The functional layer is made of granular balls, which are mainly metal oxides, to achieve the catalytic decomposition of captured formaldehyde.

[0010] Furthermore, the support frame is cylindrical and arranged along the length of the wrapping strip, the diameter of the support frame is 1mm, and the support frame is sewn inside the wrapping strip.

[0011] By adopting the above technical solution and using a thinner 1mm stainless steel support frame, it can be easily bent and wound, making it easy to shape, and it also has a certain degree of strong tensile strength and is not easy to break.

[0012] Furthermore, the wrapping tape covers the support frame, filter screen, and heating element, with the wrapping tape interface located near the sewn part of the support frame, and the wrapping tape interface is fixed by welding.

[0013] By adopting the above technical solution, the wrapping tape is made of non-woven fabric of PP or PET material. It is a porous medium material. When wrapped around the surface of the support frame, filter screen and heating element, it can block a certain amount of large dust particles and play a role in directional screening and adsorption.

[0014] Furthermore, the heating element includes a heating wire and a protective tube, the protective tube being sleeved and installed on the heating wire, and the protective tube is also sewn inside the wrapping tape.

[0015] By adopting the above technical solution, formaldehyde-removing activated carbon fibers can rapidly decompose formaldehyde at 40-60℃. The heating element allows for rapid heating to 50-80℃ via the heating wire. Since this product operates in a ventilated environment, the heating temperature needs to be slightly higher than the optimal temperature required for formaldehyde decomposition by the activated carbon fibers. To avoid safety issues, an insulating and thermally conductive material is applied to the surface of the heating wire, and the protective tube is made of a soft, pressure-resistant material, facilitating deformation during winding. The heat-conducting tube can be made of silicone or a regular flexible tube coated with thermally conductive silicone grease or adhesive double-sided thermally conductive tape. Alternatively, thermally conductive silicone cloth can be directly wrapped around the surface of the heating wire.

[0016] Furthermore, the protective tube is provided with multiple mounting ring grooves at the contact point with the filter screen. The mounting ring grooves are arranged in an array along the length of the protective tube, and a snap-fit ​​ring opening is provided on the side of the mounting ring groove near the filter screen.

[0017] By adopting the above technical solution, the protective tube extends and is fixed to the filter screen. The side of the filter screen can be snapped into the snap ring to ensure that heat can be transferred through contact, reducing the loss caused by air transfer.

[0018] Furthermore, the support bones are rectangular strips and are fixedly installed on both sides of the filter screen. Multiple support bones form a V-shape connected end to end, and adjacent support bones are discontinuously staggered.

[0019] By adopting the above technical solution, the supporting bone provides support for the winding tape without affecting the winding of the winding tape, ensuring that the winding tape structure is stable and not easy to fall apart.

[0020] Furthermore, the sealing element is sleeved on both ends of the packaging tape, and a snap-fit ​​ring is provided inside the sealing element corresponding to the support frame and the heating element. A control element is also connected to one end of the sealing element, and the control element is electrically connected to the heating element.

[0021] By adopting the above technical solution, the sealing component seals both ends of the package and protects the support frame and heating component. The control component is electrically connected to the heating component to provide power to the heating component. Various charging devices with connecting wires can be used, or a battery box can be directly installed for power supply.

[0022] In summary, the technical solution of this utility model has the following advantages:

[0023] 1. The carbon fiber filter winding tape provided by this utility model consists of a filter screen and a wrapping tape, and is internally provided with a support frame and support bones for support operation. It can be flexibly positioned as a flat filter tape or a wound filter tape, and can be adapted to different usage scenarios, making it highly practical.

[0024] 2. The carbon fiber filter winding tape provided by this utility model has a heating element inside the winding tape. The heating element is actively heated by power supply through the control element, which greatly improves the adsorption effect of the material on formaldehyde. Attached Figure Description

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0033] A type of carbon fiber filter winding tape, such as Figure 1 , Figure 2 and Figure 3 As shown, the filter includes a wrapping tape 1, a support frame 2, a filter screen 3, and a heating element 4. The support frame 2, filter screen 3, and heating element 4 are all installed inside the wrapping tape 1. The support frame 2 and heating element 4 are arranged along the length of the filter screen 3 and are positioned opposite each other on both sides of the filter screen 3's width. Sealing pieces 6 are provided at both ends of the wrapping tape 1, and the heating element 4 extends beyond the sealing pieces 6 at both ends. Supporting bones 5 are also provided on the surface of the filter screen 3. The filter wrapping tape consists of the filter screen 3 and the wrapping tape 1, with the support frame 2 and supporting bones 5 inside for support. It can be flexibly positioned as a flat filter tape or a wound filter tape, adapting to different usage scenarios, making it highly practical. Adding a heating element 4 inside the wrapping tape 1, along with the sealing pieces 6 and connecting to an electrical component, enables internal product heating, improving the formaldehyde decomposition catalytic effect and increasing the efficiency of formaldehyde removal.

[0034] Sealing components 6 are fitted onto both ends of the packaging tape 1. Inside the sealing component 6, corresponding to the support frame 2 and the heating element 4, there are snap-fit ​​rings 61. A control component 62 is also connected to one end of the sealing component 6, and the control component 62 is electrically connected to the heating element 4. The sealing component 6 seals both ends of the packaging tape 1 and protects the support frame 2 and the heating element 4. The control component 62, electrically connected to the heating element 4, provides power to the heating element 4. It can be powered by various charging devices with connecting cables, or by directly installing a battery box.

[0035] like Figure 2 and Figure 3 As shown, the wrapping tape 1 wraps and covers the support frame 2, filter screen 3, and heating element 4. The interface of the wrapping tape 1 is located near the sewn part of the support frame 2, and the interface of the wrapping tape 1 is fixed by welding. The wrapping tape 1 is made of non-woven fabric of PP or PET material. It is a porous medium material. When wrapped around the surface of the support frame 2, filter screen 3, and heating element 4, it can block a certain amount of large dust particles and play a role in directional screening and adsorption.

[0036] like Figure 2 As shown, the filter 3 includes, from top to bottom, an antibacterial layer 32, a functional layer 33, a filter layer 31, and another functional layer 33 and antibacterial layer 32. The functional layer 33 consists of arrayed granular balls. The functional layer 33 and the antibacterial layer 32 are hot-pressed together on the upper and lower sides of the filter layer 31. The filter layer 31 is made of activated carbon fiber and has undergone modification treatment to increase the formaldehyde capture and catalytic function of the activated carbon fiber. The antibacterial layer 32 is set on the upper and lower sides of the filter layer 31 to reduce the influence of water vapor and humidity. The functional layer 33 consists of granular balls set between the antibacterial layer 32 and the filter layer 31. It is mainly composed of metal oxides to achieve the catalytic decomposition of captured formaldehyde.

[0037] like Figure 3 As shown, the support frame 2 is cylindrical and arranged along the length of the wrapping strip 1. The diameter of the support frame 2 is 1mm, and the support frame 2 is sewn inside the wrapping strip 1. The 1mm thin stainless steel support frame 2 can be easily bent and wrapped, making it easy to shape, and it also has a certain degree of tensile strength, making it less prone to breakage.

[0038] The heating element 4 includes a heating wire 41 and a protective tube 42. The heating wire 41 is installed inside the protective tube 42, and the protective tube 42 is sleeved on the heating wire 41. The protective tube 42 is also sewn inside the wrapping tape 1. Formaldehyde-removing activated carbon fibers can rapidly decompose formaldehyde at 40-60℃. The heating element 4 allows the heating wire 41 to quickly raise the temperature to 50-80℃. Since this product is used in a ventilated environment, the heating temperature needs to be slightly higher than the optimal temperature required for formaldehyde decomposition by the activated carbon fibers. To avoid certain safety issues, an insulating and thermally conductive material is applied to the surface of the heating wire 41, and the protective tube 42 is made of a soft, pressure-resistant material, facilitating deformation during winding. Multiple mounting ring grooves 421 are provided at the contact point between the protective tube 42 and the filter screen 3. The mounting ring grooves 421 are arranged in an array along the length of the protective tube 42, and a snap-fit ​​ring opening 422 is provided on the side of the mounting ring groove 421 closest to the filter screen 3. The protective tube 42 extends and is installed with the ring groove 421 to fix the filter screen 3. The side of the filter screen 3 can be snapped into the snap ring 422 to ensure that heat can be transferred through contact and reduce the loss caused by air transfer.

[0039] like Figure 2 and Figure 3 As shown, the support ribs 5 are rectangular strips and are fixedly installed on both sides of the filter screen 3. Multiple support ribs 5 form a V-shape connected end to end, and adjacent support ribs 5 are intermittently staggered. The support ribs 5 provide support for the winding tape without affecting the winding of the winding tape, ensuring that the winding tape structure is stable and not easily scattered.

[0040] like Figure 1 and Figure 4 As shown, the finished wrapping tape is spirally wound around the corresponding device structure for application, with the outermost wrapping tape 1 also being spiral-shaped. For example, it can be placed at the air inlet and outlet of a household air purifier or fresh air system by wrapping or hanging, and powered via a fast power connector. This achieves the purpose of quickly removing formaldehyde. It can also be installed inside household cabinets, either laid flat at the bottom or wrapped around clothes hangers, without affecting storage space while still removing formaldehyde. It can also be used in drain cabinet spaces, such as those with strong odors, by wrapping it around the drain pipes to effectively absorb various odors emitted from the drain pipes, effectively keeping the air inside the drain cabinet clean.

[0041] The working principle and usage of this carbon fiber filter wrapping tape are as follows: The filter layer 31 is made of modified carbon fiber, and the upper and lower sides of the filter layer 31 are composite with functional layers 33 and antibacterial layers 32. The filter screen 3 is cut into a suitable size according to the size of the wrapping tape. The wrapping tape 1 is selected and the support frame 2 and heating element 4 are sewn inside. Then the filter screen 3 with surface support bone 5 is installed on the wrapping tape 1, and the interface of the wrapping tape 1 is welded and fixed. Sealing parts 6 are set at both ends of the wrapping tape 1 and suitable control parts 62 are connected.

[0042] The foregoing description illustrates and describes preferred embodiments of the present invention. As previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or related technical or knowledge. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
