Description

Technical Field

[0001] This utility model relates to the field of sponge technology, and in particular to fatigue-resistant, low-density, flame-retardant sponge. Background Technology

[0002] Fatigue-resistant, low-density flame-retardant foam is used in mattresses, chairs, and sofas to provide heat insulation, sound insulation, and flame retardancy, ensuring home safety and security. Therefore, fatigue-resistant, low-density flame-retardant foam is needed to provide both comfort and enhanced safety.

[0003] Fatigue-resistant, low-density flame-retardant sponge possesses excellent flame-retardant properties. When facing fire risks, it can effectively prevent the spread of fire without producing toxic smoke, providing strong protection for life and property safety. Its fatigue-resistant characteristics make it resistant to deformation and retain its elasticity over long-term use, maintaining stable performance in furniture, sofas, mattresses, and car seats where frequent stress occurs.

[0004] Existing fatigue-resistant low-density flame-retardant sponges, which are flame-retardant sponges composed of polyether polyols, use chemical raw materials and additives, posing potential hazards to the environment and human health. They can cause pollution and damage to the human respiratory system. Moreover, the additives can make the fatigue-resistant low-density flame-retardant sponge less elastic, which to some extent affects the air circulation and elastic recovery speed inside the sponge. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides fatigue-resistant low-density flame-retardant sponge, which aims to improve the problem that flame-retardant sponges composed of polyether polyols cause pollution and damage to the human respiratory system, and that additives make the fatigue-resistant low-density flame-retardant sponge not rebound fast enough.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a fatigue-resistant, low-density flame-retardant sponge, comprising a lower friction layer, a flame-retardant mesh on top of the lower friction layer, a high-resilience layer on top of the flame-retardant mesh, an anti-slip groove on top of the high-resilience layer, a reinforcing layer fixedly connected to the top of the high-resilience layer, a protective sleeve fixedly connected to the top of the reinforcing layer, a breathable layer on top of the protective sleeve, a sponge layer on top of the breathable layer, a high-resilience layer fixedly connected to the top of the sponge layer, and an inflation mechanism on the outside of the protective sleeve for inflating the device.

[0007] As a further description of the above technical solution:

[0008] The inflation mechanism includes an air pump, which is fixedly connected to the left front end of the protective sleeve. An air bag is fixedly connected to the inner side of the protective sleeve. The output end of the air pump passes through the protective sleeve and is fixedly connected to the air bag. Sliding grooves are provided on both the left and right sides of the inner wall of the protective sleeve. A heat dissipation layer is slidably connected to the sliding grooves. Fixing brackets are fixedly connected to the front and rear sides of the inner wall of the protective sleeve.

[0009] As a further description of the above technical solution:

[0010] The top of the lower friction layer has multiple grooves, and flame-retardant balls are fixedly connected to the inner side of each of the multiple grooves.

[0011] As a further description of the above technical solution:

[0012] An air outlet is connected to the front right end of the air bag, and a cap is threaded onto the right side of the outer wall of the air outlet.

[0013] As a further description of the above technical solution:

[0014] The outer wall of the protective sleeve is provided with two grooves on both the front and back sides, and a handle is fixedly connected to the inner side of each groove.

[0015] As a further description of the above technical solution:

[0016] A placement box is fixedly connected to the front left end of the protective cover. A controller is provided inside the placement box, and the controller is electrically connected to the air pump.

[0017] As a further description of the above technical solution:

[0018] The outer wall of the reinforcing layer has a circular hole on both the front and rear sides, and a flame-retardant strip is fixedly connected to the inner side of each circular hole.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the flame-retardant mesh on the lower friction layer can effectively prevent the spread of fire in the event of a fire or accident. The high resilience layer on the flame-retardant mesh not only increases the elasticity of the sponge, allowing it to quickly return to its original shape after being compressed, but also includes a reinforcing layer that enhances the overall ability of the sponge to withstand greater pressure and tension, making it less prone to deformation and damage.

[0023] 2. In this utility model, the air pump is tightly and reliably connected to the protective cover and air bag, ensuring a stable and efficient inflation process. The sliding grooves on the left and right sides of the inner wall of the protective cover have heat dissipation layers.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a fatigue-resistant, low-density flame-retardant sponge, comprising a lower friction layer 1, a flame-retardant mesh 21 on the top of the lower friction layer 1 to prevent the spread of fire, a high-resilience layer 3 on the top of the flame-retardant mesh 21, an anti-slip groove 4 on the top of the high-resilience layer 3, a reinforcing layer 5 fixedly connected to the top of the high-resilience layer 3 to allow for rapid recovery after being compressed, a protective sleeve 6 fixedly connected to the top of the reinforcing layer 5 to protect internal components, a breathable layer 7 on the top of the protective sleeve 6 to allow the sponge to effectively maintain breathability, a sponge layer 8 on the top of the breathable layer 7 for comfortable use, a high-resilience layer 9 fixedly connected to the top of the sponge layer 8 to withstand greater pressure, and an inflation mechanism 2 on the outside of the protective sleeve 6 for inflating the equipment.

[0033] Specifically, the lower friction layer 1 provides basic support and wear resistance, enhancing the stability of the overall structure. The flame-retardant mesh 21 is placed on top of the lower friction layer 1 to effectively prevent the spread of fire and ensure safety. The high-resilience layer 3 is located above the flame-retardant mesh 21 and can quickly recover its shape to adapt to different pressures. The anti-slip groove 4 is on top of the high-resilience layer 3 to increase friction and prevent slippage during use. The reinforcing layer 5 is fixed on the high-resilience layer 3 to enhance compressive strength and maintain structural integrity. The protective sleeve 6 wraps the internal components, providing additional protection. The breathable layer 7 ensures good breathability of the sponge and avoids heat accumulation. The sponge layer 8 serves as the contact surface, providing a comfortable user experience. The second high-resilience layer 9 is on top of the sponge layer 8 to improve pressure resistance and adapt to greater loads.

[0034] Reference Figure 1 , Figure 2 and Figure 4 The inflation mechanism 2 includes an inflation pump 201, which is fixedly connected to the left front end of the protective sleeve 6 for protection. An air bag 202 is fixedly connected to the inner side of the protective sleeve 6 for storing gas. The output end of the inflation pump 201 passes through the protective sleeve 6 and is fixedly connected to the air bag 202. Slide grooves 204 are provided on both the left and right sides of the inner wall of the protective sleeve 6. A heat dissipation layer 203 is slidably connected to the slide grooves 204 for protecting the heat dissipation of the equipment. Fixing brackets 205 are fixedly connected to the front and rear sides of the inner wall of the protective sleeve 6 for strengthening the fixation of the air bag 202.

[0035] Specifically, the air pump 201, driven by a power source, begins to draw in external air and compress it, outputting it to the air bag 202. When the air pump 201 is running, gas enters the air bag 202 through the output end, and the air bag 202 gradually expands, storing gas to provide the necessary air pressure. The slide 204 allows the heat dissipation layer 203 to move internally, ensuring that the equipment does not overheat during operation, thus improving overall safety and performance. The heat dissipation layer 203 is connected to the inner wall of the protective sleeve 6 through the slide 204, increasing air circulation. The fixing bracket 205 enhances the stability of the air bag 202, ensuring that the air bag 202 does not deform or shift during inflation and operation.

[0036] Reference Figure 2 and Figure 5 The top of the lower friction layer 1 has multiple grooves 10, and flame-retardant balls 11 are fixedly connected to the inner side of each groove 10 to prevent fire. The right front end of the gas bag 202 is connected to an air outlet 12, and a cap 13 is threadedly connected to the right side of the outer wall of the air outlet 12 to release gas. The front and rear sides of the outer wall of the protective sleeve 6 have grooves 14, and handles 15 are fixedly connected to the inner side of each groove 14 for easy movement.

[0037] Specifically, multiple grooves 10 are provided on the top of the lower friction layer 1. These grooves 10 provide specific installation positions for the flame-retardant balls 11. When faced with a fire threat, the flame-retardant balls 11 play a key fire-prevention role. The air outlet 12 on the front right side of the air bag 202 is an important channel for controlling the release of gas inside the air bag 202. The cap 13 with a threaded connection on the right side of the outer wall of the air outlet 12 plays a role in sealing and controlling the gas outflow. The grooves 14 on the front and rear sides of the outer wall of the protective sleeve 6 provide installation space for the handle 15. The handle 15 is fixedly connected to the inside of the groove 14 to ensure stability during movement.

[0038] Reference Figure 1 , Figure 2 and Figure 5 The protective sleeve 6 has a placement box 22 fixedly connected to the front left side. The placement box 22 has a controller 16 inside for placing the controller 16. The controller 16 is electrically connected to the air pump 201 for precise control. The outer wall of the reinforcing layer 5 has a circular hole 17 on both the front and back sides. The inner side of the circular hole 17 is fixedly connected to a flame retardant strip 18 to prevent fire. The top of the high resilience layer 3 has a circular hole 29 on both the front and back sides. The inner side of the circular hole 29 is fixedly connected to a buffer spring 20 to provide high elasticity.

[0039] Specifically, the placement box 22 on the front left side of the protective cover 6 provides a dedicated space for the controller 16. The controller 16 plays a key role in the whole system. The controller 16 is electrically connected to the air pump 201 and can accurately control the working state of the air pump 201. The flame-retardant strip 18 fixedly connected in the round hole 17 on the front and rear sides of the outer wall of the reinforcing layer 5 plays an important role in fire prevention. The buffer spring 20 fixedly connected in the round hole 2 19 on the front and rear sides of the top of the high-resilience layer 3 is mainly used to provide high elasticity.

[0040] Working principle: The lower friction layer 1 is located at the bottom of the sponge structure, and its main function is to increase the friction with the contact surface. The flame-retardant mesh 21 is set on the top of the lower friction layer 1, which plays a key role in fire prevention. The high resilience layer 3 is set on the top of the flame-retardant mesh 21, which has excellent elastic recovery performance. The reinforcement layer 5 is fixed on the top of the high resilience layer 3, which is mainly used to enhance the overall strength and durability of the sponge and can withstand greater pressure and tension. The top of the reinforcement layer 5 is fixedly connected to the protective sleeve 6, which protects the internal structure of the sponge. The top of the protective sleeve 6 is set with a breathable layer 7, which ensures air circulation and improves the breathability of the sponge. The sponge layer 8 is the main part of the entire structure, providing a soft touch and a certain elastic support.

[0041] The air pump 201 is fixedly connected to the left front end of the protective sleeve 6. Its fixed position ensures stability during operation. When the air bag 202 needs to be inflated, the air pump 201 starts, draws in external air, pressurizes it through the output end, and delivers it to the air bag 202. The air bag 202 is fixedly connected to the inside of the protective sleeve 6, providing a space for the air pump 201 to store gas. The sliding grooves 204 on the left and right sides of the inner wall of the protective sleeve 6 are slidably connected to the heat dissipation layer 203, providing air performance for the entire sponge. The fixing brackets 205 on the front and rear sides of the inner wall of the protective sleeve 6 are mainly used to strengthen the fixation of the air bag 202. The fixing brackets 205 provide additional support and fixing points for the air bag 202, preventing excessive displacement and deformation of the air bag 202 during inflation or when subjected to external forces.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
