[0001] This application claims the benefit of Chinese patent application No. 2023107896584, filed on June 29, 2023, and Chinese patent application No. 2023216903258, filed on June 29, 2023. This application incorporates the entirety of the aforementioned Chinese patent application. Technical Field

[0002] The present application relates to the field of mattresses, and in particular to an air supply assembly for a bed and a dehumidifying mattress. Background Art

[0003] When people sleep, they will cover themselves with quilts. As they sleep, the humidity in the quilt will rise as the body's water is discharged, causing dampness, which will reduce the quality of the sleeping environment and cause sleep discomfort.

[0004] Currently, a mattress is provided with a ventilation duct inside and a fan at the rear end of the mattress to deliver air into the ventilation duct to dry the mattress. However, installing the ventilation duct inside the mattress is very complex in manufacturing, increasing the production cost and reducing production efficiency.

[0005] Summary of the Invention

[0006] The technical problem to be solved by this application is to overcome the defect in the prior art that the process of laying pipes inside the mattress is very complicated, which increases the processing and production cost of the mattress, and to provide a bed air supply component and a dehumidifying mattress.

[0007] This application solves the above technical problems through the following technical solutions:

[0008] A bed air supply assembly comprises a first layer of mattress and a second layer of mattress, wherein the lower surface of the first layer of mattress and the upper surface of the second layer of mattress are bonded to form a mattress body, a plurality of air supply channels are formed between the first layer of mattress and the second layer of mattress, a fan accommodating cavity for accommodating a fan is provided at the edge of the mattress body, a plurality of the air supply channels are connected to the fan accommodating cavity, and a plurality of air holes are provided on the first layer of mattress that pass through the first layer of mattress and are connected to the air supply channels.

[0009] In this solution, the aforementioned structure, formed by the bonding of the first and second layers of padding, creates multiple air supply channels, eliminating the need for re-plumbing within the pad body. The air supply channels formed by bonding connect to the fan housing, allowing air generated by the fan to be directly discharged into the air supply channels. Multiple air holes extend through the first layer of padding and connect to the air supply channels, allowing air within the air supply channels to be discharged through the holes to the outer surface of the pad body. The air within the air supply channels dehumidifies and heats the pad body surface.

[0010] Preferably, the lower surface of the first layer of pad is provided with an upper ventilation groove, and the upper ventilation groove and the upper surface of the second layer of pad form the air supply channel; and / or, the upper surface of the second layer of pad is provided with a lower ventilation groove, and the lower ventilation groove and the lower surface of the first layer of pad form the air supply channel.

[0011] In this solution, the aforementioned structure is employed. By providing ventilation slots on the lower surface of the first or upper surface of the second mattress, when the first and second mattresses are bonded, the slots form a channel with the surface of the other mattress, thereby forming an air supply channel. This bonded air supply channel eliminates the need for additional piping, reducing manufacturing complexity and the weight of the mattress itself, thereby improving production efficiency and lowering costs. Furthermore, the bonded air supply channel eliminates the risk of internal piping shifting or deformation during mattress use.

[0012] Preferably, the material of the first pad layer is polyurethane foam material, and the material of the second pad layer is sponge; and / or the material of the first pad layer is sponge, and the material of the second pad layer is polyurethane foam material.

[0013] In this solution, the aforementioned structure and the choice of polyurethane foam material allow the first and second layers of cushioning to be integrally formed. The polyurethane foam material exhibits excellent elasticity and is lightweight, resulting in a lightweight cushion body and a comfortable sleeping experience. Furthermore, the polyurethane foam material offers excellent airtightness, allowing the air supply channel formed by the bonding of the polyurethane foam and sponge material to effectively transmit air, ensuring the proper function of the bed's air supply assembly.

[0014] Preferably, the first layer of pad and the second layer of pad are integrally formed.

[0015] In this solution, the above-described structure is adopted. The integrally formed first and second gasket layers provide a strong seal, preventing gas leakage. Furthermore, processing is simplified, eliminating multiple assembly steps and improving production efficiency. Furthermore, the seal of the gasket body formed by the first and second gasket layers is enhanced, ensuring the tightness of the air supply channel, allowing gas to flow effectively within the channel.

[0016] Preferably, the fan accommodating chamber is arranged in the middle of the tail of the pad body.

[0017] In this embodiment, the fan housing chamber is located in the middle of the rear portion of the mattress body, with three sidewalls facing the mattress body. The sidewall directly opposite the center of the mattress body is connected to the air supply duct, allowing air from the fan to be discharged into the air supply duct and then blown toward the center of the mattress body, achieving dehumidification of the mattress body.

[0018] Preferably, the fan accommodating cavity is arranged at the corner of the pad body.

[0019] In this solution, using the aforementioned structure, when the fan chamber is located at a corner of the cushion body, two sidewalls of the chamber face away from the cushion body. The two sidewalls facing away from the cushion body can be provided with air inlets. The remaining two sidewalls of the chamber face toward the cushion body, with one of the sidewalls connected to the air supply duct. This allows the fan to have two air inlets, increasing the amount of air the fan can inhale per unit time, thereby increasing the amount of air discharged into the air supply duct.

[0020] Preferably, the distribution density of the air holes gradually increases as the air supply channel moves away from the fan accommodating chamber.

[0021] In this solution, the above-mentioned structural form is adopted, and the air supply channel gradually moves away from the fan accommodating chamber and approaches the human body. The human body needs to be dehumidified, so the density of the air vents gradually increases so that more gas in the air supply channel can reach the surface of the pad body through the air vents. Through the action of the heated wind, the surface of the pad body can be kept dry to achieve dehumidification of the inside of the quilt during sleep.

[0022] Preferably, the first layer of pad is provided with a plurality of weight-reducing holes; and / or the second layer of pad is provided with a plurality of weight-reducing holes.

[0023] In this solution, the above-mentioned structural form is adopted, and the weight-reducing holes are added to reduce the mass of the first and second pad layers, thereby reducing the total mass of the pad body formed by the first and second pad layers.

[0024] A dehumidifying mattress uses the bed air supply assembly.

[0025] In this solution, the aforementioned structural form enables the installation of a bed air supply assembly, eliminating the need for ventilation ducts within the dehumidifying mattress. This reduces the number of ventilation ducts required, simplifying the manufacturing process of the dehumidifying mattress. Furthermore, the absence of ventilation ducts reduces the weight of the dehumidifying mattress.

[0026] Preferably, the dehumidifying mattress also includes a fan, which is arranged in the fan accommodating cavity. An air inlet channel is formed between the first layer of pad and the second layer of pad and is connected to the fan accommodating cavity. An air inlet is provided on the outside of the accommodating cavity facing away from the pad body.

[0027] In this embodiment, the aforementioned structure is employed, and an air inlet channel is formed between the first and second layers of the mattress. This allows the fan to be supplied with air through the air inlet channel within the mattress body when the air inlet is blocked by the quilt, ensuring the fan's normal operation. By installing the fan within the fan housing, the fan can blow air into the air supply channel.

[0028] The positive progress of this application is:

[0029] By providing an air supply channel formed by the first and second layers of padding, the need for ventilation ducts within the dehumidifying mattress is eliminated, thereby reducing the difficulty of manufacturing the dehumidifying mattress and reducing the weight of the dehumidifying mattress. Furthermore, an air inlet channel is provided within the pad body, further ensuring the air supply of the fan. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The present application is further described below by way of examples, but the present application is not limited to the scope of the examples.

[0039] Example 1

[0040] As shown in Figures 1, 2, 3, 6, and 7, this embodiment discloses an air supply assembly for a bed, which includes a first layer of pad 21 and a second layer of pad 22. The lower surface of the first layer of pad 21 and the upper surface of the second layer of pad 22 are bonded together to form a pad body 2. A plurality of air supply channels 11 are formed between the first layer of pad 21 and the second layer of pad 22. A fan 42 accommodating chamber 4 for accommodating a fan 42 is provided at the edge of the pad body 2. The plurality of air supply channels 11 are connected to the fan 42 accommodating chamber 4. The first layer of pad 21 is provided with a plurality of air holes 213 that pass through the first layer of pad 21 and are connected to the air supply channels 11. The plurality of air supply channels 11 formed by bonding the first layer of pad 21 and the second layer of pad 22 eliminates the need to re-lay pipes in the pad body 2, thus eliminating the need for additional pipes during the assembly of the air supply assembly. The air supply channel 11 formed by the bonding of the first layer of pad 21 and the second layer of pad 22 is connected to the fan 42 accommodating chamber 4, so that the wind generated by the fan 42 can be directly discharged into the air supply channel 11 through the air outlet 5, and there is no connection gap between the accommodating chamber 4 and the air supply channel 11, so that the wind generated by the fan can all enter the air supply channel 11, avoiding the leakage of wind in the fan during the connection process. In addition, the addition of pipelines will increase the overall weight of the bed air supply assembly, thereby increasing the weight of the mattress and making it more difficult to transport the mattress. The air supply channel 11 formed by bonding reduces the weight of the bed air supply assembly, thereby facilitating transportation. A plurality of air vents 213 pass through the first layer of pad 21 and are connected to the air supply channel 11, so that the gas in the air supply channel 11 can be discharged to the outer surface of the pad body 2 through the air vents 213. The wind generated by the fan will first be discharged into the air supply channel 11, and then transmitted through the air supply channel 11. The transmitted wind flows in the air supply channel 11 and is discharged through the air vents 213, thereby reaching the surface of the pad body 2 to dry the pad body 2.

[0041] In this embodiment, the lower surface of the first layer of padding 21 is provided with an upper ventilation slot, which forms an air supply channel 11 with the upper surface of the second layer of padding 22. By providing the ventilation slot on the lower surface of the first layer of padding 21, when the first and second layers of padding 21 and 22 are bonded together, the ventilation slot can form a channel with the surface of the other layer of padding, thereby forming the air supply channel 11. The bonding of the first and second layers of padding 21 and 22 eliminates the need for laying additional piping for the air supply channel 11, reducing manufacturing complexity and the weight of the pad body 2, thereby improving production efficiency and lowering costs. Furthermore, the bonded air supply channel 11 eliminates the risk of internal pipes shifting or being squeezed and deformed over time.

[0042] In other embodiments, the upper surface of the second layer of padding 22 is provided with lower ventilation slots, which together with the lower surface of the first layer of padding 21 form an air supply channel 11. By providing ventilation slots on the lower surface of the first layer of padding 21, when the first and second layers of padding 21 and 22 are bonded together, the ventilation slots can form a channel with the surface of the other layer of padding, thereby forming the air supply channel 11. The bonding of the first and second layers of padding 21 and 22 eliminates the need for laying additional piping for the air supply channel 11, reducing manufacturing complexity and the weight of the pad body 2, thereby improving production efficiency and lowering costs. Furthermore, the bonded air supply channel 11 eliminates the risk of internal pipes shifting or being squeezed and deformed during use.

[0043] In this embodiment, the material of the first layer of pad 21 is polyurethane foam material, and the material of the second layer of pad 22 is sponge. Through the selection of polyurethane foam material, the first layer of pad 21 and the second layer of pad 22 can be produced in one piece, and the polyurethane foam material has good elasticity and is light in weight, so that the overall weight of the pad body 2 is light and has a good sleeping experience. In addition, the polyurethane foam material has good airtightness, so that the air supply channel 11 formed after the polyurethane foam material and the sponge material are bonded together can effectively transmit the wind, and the wind generated by the fan can be fully discharged into the air supply channel 11 for transmission, ensuring the normal use of the bed air supply assembly to achieve drying treatment of the surface of the pad body 2. The ventilation grooves are opened in the layer of pad made of polyurethane foam material to make the sealing effect of the air supply channel 11 better.

[0044] In other embodiments, the first layer of pad 21 is made of sponge, and the second layer of pad 22 is made of polyurethane foam. The choice of polyurethane foam allows the first and second layers of pad 21, 22 to be integrally formed. Furthermore, the polyurethane foam has excellent elasticity and is lightweight, resulting in a lighter overall pad body 2 and a better sleeping experience. Furthermore, the polyurethane foam has excellent airtightness, allowing the air supply channel 11 formed by laminating the polyurethane foam and sponge material to effectively transmit wind. The wind generated by the fan can be fully discharged into the air supply channel 11 for transmission, ensuring the normal use of the bed air supply assembly and achieving drying of the surface of the pad body 2.

[0045] In this embodiment, the first layer of pad 21 and the second layer of pad 22 are integrally formed. The integrally formed first layer of pad 21 and second layer of pad 22 enhance the sealing performance of the pad layer, making it less likely for gas to be lost. The ventilation slots are directly opened on the first layer of pad 21 or the second layer of pad 22, and after bonding, an air supply channel 11 is formed to achieve wind transmission. The good sealing performance ensures the sealing performance of the air supply channel 11 and the wind transmission efficiency. In addition, the integral molding process facilitates processing, avoids multiple assemblies, and improves production efficiency. At the same time, the secondary combination will bring additional tolerances, and the integral molding setting can effectively avoid combination errors. In addition, the increased sealing performance of the pad body 2 formed by bonding the first layer of pad 21 and the second layer of pad 22 ensures the sealing performance of the formed air supply channel 11, so that the gas passing through the air supply channel 11 can effectively flow within the air supply channel 11.

[0046] As shown in Figures 1, 2, 3, 6, and 7, in this embodiment, the fan 42 housing chamber 4 is located in the center of the rear end of the mattress body 2. When the fan 42 housing chamber 4 is located in the center of the rear end of the mattress body 2, three sidewalls of the fan 42 housing chamber 4 face the mattress body 2. The sidewall facing the center of the mattress body 2 is connected to the air supply duct 11, allowing air from the fan 42 to be discharged into the air supply duct 11 through the air outlet 5 and then blown toward the center of the mattress body 2, thereby dehumidifying the mattress body 2. Furthermore, the sidewall of the housing chamber facing away from the center of the mattress body 2 is provided with an air inlet 41. The air inlet 41 is directly exposed to the outside air, allowing the fan 42 to draw in a large amount of air and discharge it into the air supply duct 11 in a straight line. This allows the wind speed entering the air supply duct 11 to remain at its maximum value, thereby reducing energy loss.

[0047] As shown in Figure 2, in this embodiment, the distribution density of the air holes 213 gradually increases as the air supply channel 11 moves away from the fan 42 accommodating chamber 4. As the air supply channel 11 gradually moves away from the fan 42 accommodating chamber 4 and approaches the human body, the human body will be covered by the quilt during sleep, and the moisture in the human body will continuously evaporate and enter the space formed by the quilt and the mattress, thereby increasing the humidity inside the quilt. Therefore, the human body needs to be dehumidified. The density of the air holes 213 gradually increases, so that more gas in the air supply channel 11 can reach the surface of the pad body 2 through more air holes 213. The heated wind can keep the surface of the pad body 2 dry, thereby achieving dehumidification of the inside of the quilt during sleep. The high-density arrangement of the air holes 213 ensures the dehumidification effect inside the quilt, improving the quality of sleep and use.

[0048] As shown in Figures 3 and 5, in this embodiment, the first layer of pad 21 is provided with multiple weight-reducing holes 211; by adding the weight-reducing holes 211, the mass of the first layer of pad 21 and the second layer of pad 22 can be reduced, thereby reducing the total mass of the pad body 2 formed by the first layer of pad 21 and the second layer of pad 22.

[0049] In other embodiments, the second layer of padding 22 is provided with multiple weight-reducing holes 211. The addition of these weight-reducing holes 211 reduces the mass of the first and second layers of padding 21, 22, and thus the total mass of the mat body 2 formed by the first and second layers of padding 21, 22. This reduces the mass of the air supply assembly for the bed, facilitating transportation after completion. Furthermore, the weight-reducing holes create an air cushion space when the first and second layers of padding 21, 22 are joined, enhancing the cushioning capacity of the mat body 2 and improving the user experience of the air supply assembly for the bed.

[0050] Example 2

[0051] As shown in Figures 4 and 5, the parts of the bed air supply assembly of this embodiment 2 that are the same as those in embodiment 1 will not be described again, and only the different parts will be described. In embodiment 2, the fan 42 accommodating chamber 4 is arranged at the corners of the cushion body 2. When the fan 42 accommodating chamber 4 is arranged at the corners of the cushion body 2, the two side walls of the fan 42 accommodating chamber 4 face back and away from the cushion body 2, and the two side walls facing away from the cushion body 2 can be provided with air inlets 41. The side walls of the remaining two fan 42 accommodating chambers 4 face the cushion body 2, and one of the side walls is connected to the air supply channel 11. The fan 42 can obtain two air inlets 41, so that the amount of air that the fan 42 can inhale per unit time increases, thereby increasing the wind discharged into the air supply channel 11. The increased air intake makes the air supply capacity of the bed air supply assembly stronger, thereby improving the user experience.

[0052] This embodiment also discloses a dehumidifying mattress that utilizes the aforementioned air supply assembly for a bed. The air supply assembly eliminates the need for ventilation ducts within the dehumidifying mattress, simplifies the manufacturing process of the dehumidifying mattress, and reduces the number of ventilation ducts required. Furthermore, the weight of the dehumidifying mattress can be reduced without ventilation ducts.

[0053] In this embodiment, the dehumidifying mattress further includes a fan 42, which is disposed within a fan 42 accommodating chamber 4. An air inlet channel 1 is formed between the first and second padding layers 21, 22 and communicates with the fan 42 accommodating chamber 4. An air inlet 41 is disposed on the outer side of the accommodating chamber, facing away from the mattress body 2. The air inlet channel 1 is further formed between the first and second padding layers 21, 22. This ensures that when the air inlet 41 is blocked by the quilt, the fan 42 can be supplied with air through the air inlet channel 1 within the mattress body 2. This ensures the proper functioning of the fan 42 and prevents the fan from being unable to draw in outside air due to a blockage in the air inlet 41, causing it to become unusable. By installing the fan 42 within the fan 42 accommodating chamber 4, the fan 42 is able to blow air into the air supply channel 11, reducing energy loss during the transmission of the air generated by the fan 42 and ensuring the speed of the air generated by the fan 42.

[0054] Although the above describes specific embodiments of the present application, those skilled in the art will understand that these are merely illustrative and that the scope of protection of the present application is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present application, and such changes and modifications shall fall within the scope of protection of the present application.
