Abstract
Description
Technical Field
[0001] This utility model relates to the field of sofa cushion technology, and more specifically to an antibacterial and waterproof sofa sponge. Background Technology
[0002] Sofas are one of the most common modern home furnishings, widely loved by consumers for their softness and comfort. Sofas generally consist of an inner elastic cushion and an outer fabric. Sofa fabrics are divided into several types according to their materials and functions, the most common being leather, linen, and cotton. They are also classified according to their functions, such as waterproof, antibacterial, flame retardant, and antistatic.
[0003] With the improvement of people's living standards and aesthetic appreciation, existing sofa fabrics not only have mediocre antibacterial and waterproof effects, but also angle adjustment is generally achieved through motors or cylinders. This method is not only costly and noisy, but also has extremely poor softness of the fabric, resulting in a decline in user comfort and gradually failing to meet people's needs. In order to improve market competitiveness, this utility model provides an antibacterial and waterproof sofa sponge. Utility Model Content
[0004] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.
[0005] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide an antibacterial and waterproof sofa sponge.
[0006] To achieve the above objectives, the technical solution of this utility model is: an antibacterial and waterproof sofa sponge, comprising: a sofa cushion, which includes a polyurethane sponge pad, a layered airbag, an air tube, and an adjusting valve. The polyurethane sponge pad is installed on the layered airbag, the air tube is connected to the adjusting valve, and the air holes of the air tube are connected to the air holes of the layered airbag.
[0007] Preferably, a base is installed on the lower side of the layered airbag.
[0008] Preferably, a support plate is provided on the rear side of the base.
[0009] Preferably, the base is equipped with a control panel for controlling the operation of the regulating valve.
[0010] Preferably, the polyurethane foam pad is composed of several square blocks.
[0011] Preferably, rubber posts are inserted between the corners of the square blocks.
[0012] Preferably, a heating element and a power strip are installed inside the square block, and the heating element and the power strip are electrically connected.
[0013] The beneficial effects of this utility model are as follows: This utility model uses layered airbags and polyurethane foam pads to create a sofa cushion. The polyurethane foam pads not only provide a certain degree of waterproofing but also have excellent antibacterial properties, effectively preventing the growth of bacteria and fungi. Furthermore, the gas within the layered airbags increases the softness and comfort when sitting or leaning against the polyurethane foam pads. The adjustable valve controls the airflow through the air tubes, allowing for the release or replenishment of gas within the layered airbags, resulting in quieter and gentler adjustments to the angle and height of the polyurethane foam pads. Compared to existing sofa fabrics and adjustment mechanisms, this design is lower in cost, softer, and provides a more gradual adjustment process, thus greatly improving the comfort of the sofa fabric.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0021] Please see Figure 1-4 This utility model provides an antibacterial and waterproof sofa sponge, including: a sofa cushion, which includes a polyurethane sponge pad 1, a layered airbag 2, an air tube 3, and an adjusting valve 4. The polyurethane sponge pad 1 is installed on the layered airbag 2, the air tube 3 is connected to the adjusting valve 4, and the air holes of the air tube 3 are connected to the air holes of the layered airbag 2.
[0022] When in use, the layered airbags 2 are connected to the side of the polyurethane foam pad 1. The polyurethane foam pad 1 is made of polyurethane foam material with added antibacterial agents. The layered airbags 2 and the polyurethane foam pad 1 form a sofa cushion. Through the characteristics of the polyurethane foam pad 1, the sofa cushion not only has a certain waterproof function, but also has good antibacterial ability, which can effectively prevent the growth of bacteria, fungi, etc. In addition, the air in the layered airbags 2 increases the softness and enhances the comfort of sitting or leaning on the polyurethane foam pad 1. Furthermore, the air in the air pipe 3 is controlled by the regulating valve 4, which allows the air in the layered airbags 2 to be released or replenished, which has a quieter adjustment function for the angle and height of the polyurethane foam pad 1. The adjustment will also be more gentle, thereby improving the comfort of the sofa fabric.
[0023] According to some embodiments of this application, optionally, a base 5 is installed on the lower side of the layered airbag 2, and a support plate 6 is provided on the rear side of the base 5. This serves to support and adjust the height of the sofa.
[0024] According to some embodiments of this application, optionally, a control panel for controlling the operation of the regulating valve 4 is mounted on the base 5. This serves to facilitate the start and stop of the regulating valve 4.
[0025] According to some embodiments of this application, optionally, the polyurethane foam pad 1 is composed of several square blocks 7. The polyurethane foam pad 1 composed of several square blocks 7 gives the surface of the polyurethane foam pad 1 more recessed seams, which not only increases the anti-slip properties of the sofa fabric, but also plays a role in preventing wrinkles.
[0026] According to some embodiments of this application, optionally, rubber pillars 8 are inserted between the corners of the square blocks 7. When a user sits on or leans against the polyurethane foam pad 1, the square blocks 7 are squeezed, and the rubber pillars 8 will be slightly exposed, pressing against the user to provide support and massage, and also to increase the anti-slip effect.
[0027] According to some embodiments of this application, optionally, a heating tube 9 and a power strip 10 are incorporated inside the square block 7, and the heating tube 9 and the power strip 10 are electrically connected. Each square block 7 has a heating function, thereby allowing users to select which parts to heat according to their needs, such as legs, buttocks, waist, shoulders, etc., without needing to heat all parts, making it more suitable and more energy-efficient.
