Description

Technical Field

[0001] This utility model belongs to the field of outdoor inflatable bed technology, specifically relating to a manually pressurized inflatable sponge mattress. Background Technology

[0002] Current air mattresses generally use electric air pumps. While this design provides convenience and efficiency in daily use, it also has some obvious drawbacks, especially in certain situations where it can significantly affect the user experience and the product's practicality.

[0003] Electric air pumps require a power source to operate. In the event of a power outage or lack of electricity, such as during outdoor camping, travel, or emergencies, users will be unable to inflate or deflate the air mattress, which greatly limits its flexibility. For battery-powered air pumps, battery life is a significant concern. If the battery is not recharged or replaced promptly after it is depleted, the device will also malfunction.

[0004] Electric air pumps are typically heavier and larger than manual pumps, increasing the burden of carrying them, especially for frequent movement or long-distance travel. To ensure they are always ready to use, users also need to carry a charger or spare batteries, which not only adds to luggage weight but can also cause inconvenience if forgotten. In addition to the initial purchase cost, users also need to consider the cost of battery replacement or charging.

[0005] For frequent users, these additional costs can accumulate over time, forming a significant expense. Electrical devices are more prone to malfunctions than mechanical devices, such as short circuits and battery aging, making repairs and maintenance more complex and increasing user costs and time. High or low temperatures can affect battery performance, causing the air pump to become less efficient or even fail to start. Furthermore, humid environments can also pose a risk of damaging electrical components.

[0006] While electric air pumps offer a quick and convenient inflation experience for air mattresses, their high dependence on electricity, coupled with issues such as portability, high cost, poor environmental adaptability, and safety risks, limits their practical application. Therefore, further optimization and improvement of the air mattress structure are needed to provide a more reliable, convenient, and environmentally friendly solution. Utility Model Content

[0007] The purpose of this invention is to provide a manually operated inflatable foam mattress to solve the problems of high dependence on electricity in existing inflatable mattresses, as well as the resulting inconvenience, high cost, poor environmental adaptability, and safety risks.

[0008] To achieve the above objectives, this utility model provides an artificially pressurized inflatable foam mattress, comprising an air pump, a resilient filling body, and inflatable gas made of a flexible material; the filling body is disposed in the inflation chamber of the inflatable gas; the inflatable gas is provided with an installation groove, and the air pump is disposed in the air pump and fixedly connected to the inflatable gas;

[0009] The air pump is configured as a pressure-driven air pump, which has a one-way air intake channel connected to the inflation chamber; when the air pump is manually pressed, external gas can enter the inflation chamber through the one-way air intake channel.

[0010] In one possible design, the pressure-driven air pump includes a mounting base and an elastomer. The mounting base has a mounting cavity, a top cover is provided above the mounting base, an air inlet valve is provided on the top cover, and an air outlet valve is provided on the mounting base. The elastomer is disposed in the mounting cavity of the mounting base, and the passage between the air inlet valve, the mounting cavity, and the air outlet valve forms the one-way air inlet channel.

[0011] The density of the elastomer is greater than that of the filler. When the elastomer is pressed, the difference in rebound force between the elastomer and the filler can squeeze external gas into the inflation chamber, or squeeze the gas in the inflation chamber to the outside.

[0012] In one possible design, the top cover has an outwardly extending outer edge that is thermally fused to the gas filling gas.

[0013] In one possible design, the height of the top cover is flush with the surface of the gas filling;

[0014] And / or, both the inlet valve and the outlet valve are one-way valves, each having a movable valve core for changing the gas flow direction; wherein, in the inflation state, the airflow direction of the two one-way valves is the same, and the valve cores are arranged inwards so that external gas can be introduced into the inflation gas; in the degassing state, the valve cores are arranged inwards so that gas in the inflation gas can be discharged.

[0015] And / or, the elastomer is configured as a second sponge layer.

[0016] In one possible design, the filler has a plurality of slots extending along the width direction of the filler, and the plurality of slots are spaced apart along the length direction of the filler.

[0017] In one possible design, the slot is configured as a through hole or a groove.

[0018] In one possible design, the longitudinal cross-sectional shape of the slot is circular, triangular, square, trapezoidal, or dovetail-shaped.

[0019] In one possible design, the slots are configured in two layers and are respectively located in the upper and lower regions of the filler.

[0020] In one possible design, the inflatable gas includes a top layer, side walls, and a bottom layer. The side walls are formed in an enclosed shape, with their upper and lower ends connected to the top layer and the bottom layer, respectively. The space between the top layer and the bottom layer forms the inflatable cavity, and the filler is disposed in the inflatable cavity.

[0021] In one possible design, the filler is connected to the top layer and the bottom layer respectively by an adhesive layer.

[0022] Through the aforementioned technical solution, users can adjust the mattress firmness according to their preferences at any time to achieve the most comfortable sleep experience. Utilizing a pressure-operated air pump, inflation is achieved manually by pressing the pump. Its simple structure and lightweight design make it easy to operate, requiring no complex tools or equipment, and suitable for various scenarios, such as ordinary mattresses, sofa cushions, and car seat cushions.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that while the description of these embodiments is intended to aid in understanding the present invention, it does not constitute a limitation thereof. The specific structural and functional details disclosed herein are only for describing exemplary embodiments of the present invention. However, the present invention may be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0030] According to a specific embodiment of the present invention, a manually pressurized inflatable sponge mattress is provided. Figures 1 to 4 One specific embodiment is shown.

[0031] See Figures 1 to 4 As shown, the manually operated inflatable foam mattress includes an air pump 1, a resilient filling 2, and an inflatable gas 3 made of flexible material; the filling 2 is disposed in the inflation chamber of the inflatable gas 3; the inflatable gas 3 is provided with an installation groove, and the air pump 1 is disposed in the air pump 1 and fixedly connected to the inflatable gas 3; wherein, the air pump 1 is configured as a manually operated air pump 1, and the manually operated air pump 1 is provided with a one-way air intake channel communicating with the inflation chamber; when the air pump 1 is manually operated, external gas can enter the inflation chamber through the one-way air intake channel.

[0032] Placing the filling 2 inside the inflatable air 3 provides additional support and comfort, enhancing the mattress's elasticity and helping it maintain its shape memory. The entire mattress shell is made of flexible material, ensuring both softness after inflation and easy folding and compression for convenient storage and transport. A specific location on the inflatable air 3 securely connects to the air pump 1, ensuring its stability and operational safety. The air pump 1 is equipped with a manually operated inflation device with a one-way air intake channel, ensuring that air can only enter the inflation chamber from the outside.

[0033] The working process of this manually operated air-filled mattress is as follows: The user moves the elastic body 12 in the air pump 1 up and down by stepping on it or manually pressing it. When the elastic body 12 moves downward, it creates negative pressure to draw in air; when the piston moves upward, it compresses the air and pushes it into the inflation chamber. Each press or step repeats the above air intake and exhaust process, continuously injecting air into the inflation chamber until the desired air pressure is reached. Depending on usage needs, the user can adjust the firmness of the mattress by increasing or decreasing the number of steps. After inflation, the air inlet of the air pump 1 is closed to ensure that the air in the inflation chamber does not leak. After use, the user can open the air nozzle 4 located on the side wall of the air pump 3 to quickly expel the air from the inflation chamber. After expelling the air, the mattress can be easily folded or rolled up for easy storage and transport.

[0034] Through the above technical solution, users can adjust the firmness of the mattress at any time according to their preferences to obtain the most comfortable sleep experience. Utilizing a manual air pump 1, inflation can be achieved by manual pressing. Its simple structure and lightweight design make it easy to operate, requiring no complicated tools or equipment, and suitable for various scenarios, such as ordinary mattresses, sofa cushions, and car seat cushions. Users can inflate and deflate the mattress themselves anytime, anywhere, greatly simplifying daily life. This manually pressurized air-filled mattress avoids the problem of traditional electric air pumps 1's heavy reliance on electricity, reducing energy consumption and aligning with modern environmental protection concepts. Furthermore, its durable design reduces replacement frequency and resource waste. Thanks to the use of flexible materials and a foldable design, this mattress is very lightweight, easy to move and store. Whether for travel, camping, or everyday home use, it saves a significant amount of space.

[0035] In one embodiment, the pressure-operated air pump 1 includes a mounting base 13 and an elastic body 12. The mounting base 13 has a mounting cavity, and a top cover 11 is provided above the mounting base 13. An air inlet valve 14 is provided on the top cover 11, and an air outlet valve is provided on the mounting base 13. The elastic body 12 is disposed in the mounting cavity of the mounting base 13, and the passage between the air inlet valve 14, the mounting cavity, and the air outlet valve forms a one-way air inlet channel. The density of the elastic body 12 is greater than the density of the filler 2. When the elastic body 12 is pressed, the difference in its rebound force with that of the filler 2 can compress external gas into the inflation cavity, or compress gas in the inflation cavity to the outside. Specifically, the gas flow direction is determined by the orientation of the valve cores of the air inlet and air outlet valves (inward orientation for air intake; outward orientation for air exhaust).

[0036] The elastomer 12 has high elasticity and generates a large reaction force when pressed. When the user presses the elastomer 12, the difference in rebound force between it and the filler 2 compresses external air into the inflation chamber through the one-way air intake channel. The user steps on or manually presses the elastomer 12, compressing it and moving it downwards. During the pressing process, the large reaction force generated by the elastomer 12 causes the pressure inside the mounting chamber to increase rapidly, forcing the air intake valve 14 to open and allowing fresh air to enter the mounting chamber. As the user releases the pressure, the elastomer 12 quickly returns to its original position due to its high density, simultaneously pushing the air in the mounting chamber into the inflation chamber through the air outlet valve. Each press repeats the above-described intake and exhaust process, continuously injecting air into the inflation chamber until the required air pressure is reached.

[0037] By utilizing the high-density properties of the elastomer 12 and the difference in resilience between it and the inflator 2, a more efficient inflation process is achieved. Each press allows for more complete intake and delivery of air, reducing the time and effort required for inflation. The high-density elastomer 12 has better wear resistance and anti-aging properties, extending the service life of the air pump 1 and reducing maintenance costs. This air pump 1 does not rely on electricity, reducing energy consumption and aligning with modern environmental protection principles. Furthermore, its durable design reduces replacement frequency and minimizes resource waste.

[0038] Specifically, the top cover 11 has an outwardly extending outer edge 15, which is firmly bonded to the gas filling 3 using a hot-melt connection technology. Hot-melt connection is a common plastic welding method that fuses two plastic materials together by heating, and forms a strong connection after cooling. This helps to ensure airtightness and guarantees the reliability and safety of long-term use.

[0039] In this disclosure, the gas used for filling is an air cushion or air bed.

[0040] In this disclosure, the height of the top cover 11 is flush with the surface of the inflated air 3, which makes the mattress look flat and beautiful, avoids any protruding parts from causing discomfort to the user, and thus provides a consistent comfort experience.

[0041] In this disclosure, both the inlet valve 14 and the outlet valve are one-way valves with a movable valve core to change the gas flow direction. In the inflation state, the airflow direction of both one-way valves is the same, and the valve cores are positioned inwards to allow external gas to enter the inflation gas. In the de-inflation state, the valve cores are positioned inwards to allow gas in the inflation gas to be discharged. This allows for unidirectional and efficient gas flow, preventing backflow or leakage. It also offers good flexibility, allowing the gas flow direction to be changed according to usage requirements. Thus, a complete unidirectional air intake channel is formed, ensuring that air can only enter the inflation chamber from the outside and will not flow backwards.

[0042] It should be noted that this check valve is an existing technology product.

[0043] In this disclosure, the elastomer 12 is configured as a second sponge layer, the elasticity of which is greater than the density of the filler.

[0044] In other embodiments, the elastomer can also be other elastic materials such as latex or memory foam. Those skilled in the art can select any suitable material with an elasticity greater than that of the filler within the framework of this disclosure.

[0045] It should be noted that the term "and / or" in this article is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, B exists alone, and A and B exist simultaneously.

[0046] In one embodiment provided in this disclosure, the filling body 2 is provided with a plurality of slots 21, which extend along the width direction of the filling body 2 and are spaced apart along the length direction of the filling body 2. This special cutting allows the mattress to be easier to store while maintaining comfort. Thus, while ensuring the comfort and support of the bed, the weight is reduced by nearly half.

[0047] The slots 21 extend along the width of the filling 2, ensuring the mattress can be more easily folded or rolled up when compressed. Multiple slots 21 are spaced apart along the length of the filling 2, ensuring the mattress still provides sufficient support and comfort during use without affecting the user's sleep experience. By removing some material, the overall weight of the mattress is reduced by approximately half, making it lighter and more portable.

[0048] The slots 21 are manufactured using a cutting process to ensure that the edges of each slot 21 are smooth. The cut slots 21 not only do not affect the structural integrity of the mattress, but also enhance its elasticity and breathability, further improving comfort.

[0049] In this disclosure, the slot 21 is configured as a through hole or a groove. The presence of grooves and through holes makes the mattress easier to fold or roll, saving a significant amount of storage space, making it ideal for travel, camping, or small-apartment use. Those skilled in the art can flexibly configure it according to actual needs.

[0050] Specifically, the through-holes completely penetrate the pores of the filling 2, helping to further reduce the mattress's weight and enhance breathability. The slotted structure, an open structure with openings on only one side, extends along the width of the filling 2, with multiple slots spaced apart along the length of the filling 2. The slotted design makes the mattress easier to fold or roll up while maintaining sufficient support and comfort.

[0051] Furthermore, the longitudinal cross-sectional shape of the slot 21 is circular, triangular, square, trapezoidal, or dovetail-shaped. Designing the slot 21 with the above-described structure not only effectively maintains the comfort and support of the mattress but also reduces its weight, making it easier to store and carry. Therefore, those skilled in the art can choose any suitable shape for the slot 21 based on the technical concept of this disclosure.

[0052] Specifically, the slot 21 is formed into a circle, which can provide a uniform weight reduction effect while maintaining good structural strength.

[0053] The slot 21 is formed into a triangle, which can reduce the amount of material while increasing the elasticity and flexibility of the filler 2.

[0054] The slot 21 is square in shape, which can provide stable structural support and is suitable for areas that require stronger support.

[0055] The slot 21 is formed into a trapezoid, which not only helps to better distribute pressure but also improves the overall comfort of the mattress.

[0056] The slot 21 is formed in a dovetail shape, which can enhance the structural stability around the slot 21 and prevent tearing or deformation during use.

[0057] In this disclosure, the slots 21 are configured in two layers, located in the upper and lower regions of the filling material 2, respectively. The slots 21 in the upper region reduce weight and enhance breathability, facilitating air circulation, reducing stuffiness, and improving sleep quality. The slots 21 in the lower region optimize structural strength and reduce weight. Thus, while maintaining support, the mattress weight is further reduced.

[0058] In one embodiment, the gas filling 3 includes a top layer 31, a side wall 32, and a bottom layer 33. The side wall 32 is formed in an enclosing shape, and its upper and lower ends are respectively connected to the top layer 31 and the bottom layer 33. The space between the top layer 31 and the bottom layer 33 forms an air filling cavity, and the filling body 2 is disposed in the air filling cavity.

[0059] The top layer 31, located at the top of the inflatable layer 3, is in direct contact with the user, providing a comfortable sleeping surface. The side walls 32 are enclosed, with their upper and lower ends connected to the top layer 31 and the bottom layer 33 respectively, serving a sealing and supporting function. The bottom layer 33, located at the bottom of the inflatable layer 3, provides basic support and is in contact with the ground. The space between the top layer 31 and the bottom layer 33 forms an air chamber to hold air, providing necessary elasticity and support.

[0060] In this disclosure, both the top layer 31 and the bottom layer 33 are made of TPU composite fabric. This material possesses excellent properties such as wear resistance, durability, water resistance, and moisture resistance, which not only extends the mattress's lifespan but also ensures cleanliness and dryness during use. The side walls 32 are located between the top layer 31 and the bottom layer 33, forming an enclosed shape and playing a crucial supporting role, maintaining a certain height between the inflated air and the ground, providing additional stability and a sense of space. The air nozzles 4 on the side walls 32 facilitate inflation and deflation operations for the user, simplifying the usage process and improving convenience.

[0061] This filling layer, formed as a sponge layer, not only enhances the mattress's comfort but also provides excellent heat retention, making it suitable for use in colder environments and offering users a warm and comfortable sleep experience. An adhesive layer is provided between the sponge layer and the top layer 31 and bottom layer 33 to ensure a secure connection between the three, preventing the filling from shifting or sliding, thereby providing more reliable support and long-term durability.

[0062] The waterproof properties of the top layer 31 and the bottom layer 33 effectively prevent liquid penetration, keeping the inside of the mattress dry and suitable for various environments, including damp occasions such as outdoor camping.

[0063] In one embodiment provided in this disclosure, the filling material 2 is connected to the top layer 31 and the bottom layer 33 respectively by adhesive layers to ensure its stable fixation within the air cavity. The adhesive layers not only enhance the fixation effect of the filling material 2, but also provide a certain cushioning effect, increasing the overall comfort of the mattress.

[0064] Specifically, this disclosure uses a high-strength and durable adhesive as the bonding layer to ensure a strong and reliable connection between the filler 2 and the top layer 31 and the bottom layer 33. After bonding, appropriate pressure and curing treatments are required to ensure that the adhesive layer is fully cured and achieves the best bonding effect.

[0065] Under the technical concept of this disclosure, any suitable driver other than an electric air pump or a spring compression air pump can be selected as the driving source. Those skilled in the art can flexibly configure it according to actual needs.

[0066] Finally, it should be noted that this utility model is not limited to the above-described optional embodiments, and anyone can derive other various forms of products under the guidance of this utility model. The above specific embodiments should not be construed as limiting the scope of protection of this utility model, which should be determined by the claims, and the description can be used to interpret the claims.
