Description

Technical Field

[0001] The utility model belongs to the technical field of decorative drawing boards, in particular to a decorative drawing board with the function of absorbing formaldehyde. Background Art

[0002] In recent years, studies have proposed innovative designs that combine air purification functions with interior decoration. One of the more ideal solutions is to use decorative drawing boards. The decorative drawing boards themselves are formaldehyde-free and can not only serve as interior decoration, but also have the function of absorbing formaldehyde. By using adsorption materials such as activated carbon boards, formaldehyde and other harmful substances are adsorbed and filtered, which can not only beautify the space, but also effectively purify the indoor air.

[0003] However, during long-term use, it was found that: 1. Due to the structure of the activated carbon board itself, a substrate needs to be set up as support, but the existing substrate structure will reduce its contact area with the air, affecting the adsorption efficiency; 2. Existing decorative painting boards are often directly fixed to the wall with bolts, which will cause the gap between the decorative painting board and the wall to be smaller. When the two are relatively close, it is easy for air to be unable to circulate into the activated carbon board, and the adsorption efficiency is further reduced. In order to solve this problem, practitioners have designed a decorative painting board with the function of adsorbing formaldehyde. Utility Model Content

[0004] The purpose of the present utility model is to provide a decorative painting board with formaldehyde adsorption function in order to solve the problem that the substrate structure and the way of installation on the wall of the existing decorative painting board with formaldehyde adsorption function easily lead to poor circulation between the activated carbon board in the decorative painting board and the air, resulting in low adsorption efficiency.

[0005] The utility model achieves the above-mentioned object through the following technical solutions: a decorative painting board with formaldehyde adsorption function, comprising a picture frame body, a formaldehyde-free board component is arranged in the cavity of the picture frame body, the formaldehyde-free board component and the cavity of the picture frame body are firmly connected by a pressure strip, a embedding groove is opened on the side wall of the picture frame body, and two sets of connecting parts are slidably arranged in the embedding groove located at the upper part;

[0006] The formaldehyde-free board assembly includes an activated carbon board, a substrate and a canvas are respectively bonded to two sides of the activated carbon board, and a plurality of penetration holes are evenly distributed on the substrate.

[0007] Furthermore, the picture frame body is composed of four groups of picture frame side bars, and each group of picture frame side bars is fixed to each other by right-angle connectors.

[0008] Furthermore, the pressure strip includes two groups of supporting parts arranged opposite to each other, and an arc-shaped pressing piece is arranged between the two groups of supporting parts.

[0009] Furthermore, the connecting member includes a sliding base plate slidably arranged in the embedding groove, the sliding base plate is provided with a threaded hole, the sliding base plate is fixedly provided with an extension plate, and the extension plate is provided with a hanging groove.

[0010] Furthermore, the cross section of the extension plate is "L"-shaped, and the inner wall of the hanging groove is provided with a plurality of groups of tooth grooves.

[0011] Furthermore, the connecting member includes a sliding base plate slidably arranged in the embedding groove, the sliding base plate is provided with a threaded hole, the sliding base plate is slidably provided with an extension plate, and the extension plate is provided with a hanging groove.

[0012] Beneficial effects: The utility model has reasonable design, simple and stable structure, strong practicality, and has the following beneficial effects:

[0013] 1. Formaldehyde adsorption function: By setting an activated carbon plate inside the main body of the picture frame and setting permeable holes on its base plate, while not containing formaldehyde itself, it can effectively adsorb formaldehyde and other harmful substances in the air, improve indoor air quality, and have environmental and health protection effects. In addition, the base plate surface is provided with permeable holes to ensure that air can circulate inside the picture frame, which helps the activated carbon plate to better adsorb formaldehyde and other harmful gases, further improving the adsorption efficiency;

[0014] 2. Stable hanging structure and optimized air circulation: The design of the connector makes the hanging of the decorative drawing board more stable. At the same time, without affecting the overall aesthetics of the decorative drawing board, the gap between the decorative drawing board and the wall can be adjusted to further improve the circulation between the activated carbon board and the air, thereby increasing the adsorption efficiency.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Example 1:

[0025] Combine Figure 1-5 The decorative painting board shown has the function of absorbing formaldehyde, which includes a picture frame body 1. The picture frame body 1 is the structural core of the entire decorative painting board. A special cavity is provided in the picture frame body 1, and a formaldehyde-free board component 2 is installed in the cavity. While it does not have formaldehyde itself, it can effectively purify harmful substances in the air. The formaldehyde-free board component 2 is tightly fixed to the cavity of the picture frame body 1 through a pressure strip 3 to ensure stability and prevent shaking during use. In order to enhance the installation convenience and stability of the formaldehyde-free board component 2, a groove 4 is designed on the side wall of the picture frame body 1, and two sets of sliding connectors 5 are provided on the part above the groove 4 to facilitate the installation and fixation of the decorative painting board.

[0026] The core material of the formaldehyde-free board component 2 is the activated carbon board 201, which has a very strong ability to adsorb formaldehyde and other harmful gases. The two sides of the activated carbon board 201 are bonded with a substrate 202 and a canvas 203 respectively. The substrate 202 not only plays a supporting role, but also effectively promotes air circulation and the adsorption of harmful substances through a number of penetration holes 204 evenly distributed on its surface. The design of these holes ensures that the surface area of the activated carbon is maximized, thereby improving the adsorption effect. The canvas 203 is not further limited. Its surface can be enhanced in aesthetics by spraying and hand-painting. In addition, its surface can be coated with a film to enhance its scratch resistance as needed. In terms of overall design, the decorative painting board can beautify the space while continuously adsorbing harmful substances such as formaldehyde in the indoor air, providing fresh and healthy air for the indoor environment, and is both decorative and environmentally friendly.

[0027] In this embodiment, the picture frame body 1 is composed of four groups of picture frame side bars 101. Each group of picture frame side bars 101 is long and arranged along the four sides of the picture frame to form a rectangular frame structure. Each group of picture frame side bars 101 is fixedly connected by right-angle connectors 102. The design of the right-angle connectors 102 enables each corner of the picture frame to form a right angle stably and accurately, thereby ensuring the correct geometric shape of the entire picture frame body 1. The right-angle connectors 102 are generally made of sturdy metal or high-strength plastic material, have good connection performance, can not only provide sufficient support force, but also effectively prevent the picture frame from deformation or loosening.

[0028] The structural design of the pressure strip 3 in this embodiment is innovative and practical, and includes two groups of relatively arranged support parts 301. The design of each group of support parts 301 enables the pressure strip 3 to stably fix the formaldehyde-free board component 2 in the cavity of the picture frame body 1, ensuring that the entire device will not shake during use. A circular arc-shaped pressing piece 302 is connected between the two groups of support parts 301. The pressing piece 302 not only plays a role in evenly distributing pressure, but also can effectively perform a certain degree of compression to ensure that it can effectively work on formaldehyde-free board components 2 of different thicknesses. In addition, the circular arc shape of the pressing piece 302 can also prevent sharp edges from causing damage to the formaldehyde-free board component 2 or the picture frame body 1, further improving the safety of the entire device and the reliability of long-term use.

[0029] The design of the connecting member 5 in this embodiment focuses on the convenience of installation of the device, and mainly includes a sliding base plate 501 that is slidably arranged in the embedded groove 4 on the side wall of the picture frame body 1. The design of the sliding base plate 501 enables the connecting member 5 to slide smoothly in the embedded groove 4, thereby facilitating the installation and adjustment of the formaldehyde-free board assembly 2. In order to ensure the stability of the connecting member 5, a threaded hole 502 is provided on the sliding base plate 501, allowing the sliding base plate 501 to be fixed to the embedded groove 4 with other components by screws. An extension plate 503 is also fixedly provided on the sliding base plate 501. The extension plate 503 enhances the bearing capacity of the connecting member 5 through precise structural design, so that it remains stable and durable during long-term use. A hanging slot 504 is provided on the extension plate 503. This design allows the decorative painting board to be installed on the wall to prevent it from falling off or shifting.

[0030] In this embodiment, the cross-section of the extension plate 503 is designed to be "L"-shaped. The "L"-shaped cross-section allows the decorative painting board to be staggered with the wall after being installed on the wall, ensuring the subsequent air circulation of the substrate. In addition, the inner wall of the hanging groove 504 is designed with several groups of grooves. The presence of these grooves effectively enhances the friction force of the hanging groove 504 after hanging, thereby improving the safety and reliability of the decorative painting board after hanging.

[0031] Embodiment 2: The cooperation mode between the sliding base plate 501 and the extension plate 503 in this embodiment 2 is improved on the basis of the above embodiment. The technical contents disclosed in the above embodiment will not be described repeatedly. The contents of the above disclosed embodiment also belong to the contents disclosed in this embodiment 2.

[0032] One embodiment of the present invention, combined with Figure 6 The connecting member 5 shown includes a sliding base plate 501 that is slidably arranged in the embedded groove 4, and a threaded hole 502 is provided on the sliding base plate 501, and an extension plate 503 is slidably provided on the sliding base plate 501, and a hanging groove 504 is provided on the extension plate 503. Compared with the embodiment 1, the extension plate 503 is combined with the sliding structure of the sliding base plate 501, so that the entire structure can move smoothly during use while maintaining a good fixing effect. In this way, the gap between the decorative painting board and the wall can be adjusted according to actual needs, further increasing air circulation and enhancing the adsorption effect. However, this setting method may affect the aesthetics of some decorative painting boards when the extension plate 503 is fully pulled out. At the same time, if the decorative painting board has a large weight, it will cause poor pulling and abnormal noise for a long time.
