Description

Technical Field

[0001] This utility model relates to the field of mattress technology, specifically to a zoned air pressure adjustable inflatable mattress. Background Technology

[0002] Inflatable mattresses are widely used in home and outdoor settings due to their portability, but existing products still have many technical defects and cannot meet users' needs for support, stability and reliability.

[0003] Currently, most inflatable mattresses on the market use a single air chamber or a simple zoned structure. This structure cannot adapt to the physiological curves of different parts of the body, resulting in a lack of targeted, differentiated support and thus affecting comfort. To improve support, some high-end products use a design with multiple independent air chambers and a built-in control unit, achieving precise support through zoned control. However, these products are not only structurally complex and expensive to manufacture, but the built-in control unit and other components also increase the overall size and weight of the mattress, severely weakening the core portability advantage of inflatable mattresses. At the same time, existing inflatable mattresses generally lack effective internal shaping processes, resulting in poor overall stability and pressure resistance after inflation, making them prone to deformation under stress. Some products use a "thread-drawing process" to improve support and shaping, which uses independent upper and lower welded plates combined with multiple high-strength threads to form the internal support structure. However, this process still has significant shortcomings: firstly, the connection structure between the threads and the welded plates is complex, posing a risk of thread breakage during long-term use; secondly, the large number of welding points makes them prone to cracking and air leakage due to stress concentration, significantly reducing the product's reliability and lifespan.

[0004] In summary, existing air mattresses present a dilemma: they cannot reconcile the differences in support, the portability of the structure, and the stability and reliability of use. Therefore, how to provide an air mattress that has independent support function, is stable and reliable, and has excellent portability is a problem that needs to be solved by those skilled in the art.

[0023] Please see below. Figure 1 This utility model provides a zoned air pressure adjustable air mattress, comprising: A sealed air cavity 100 is formed by an upper piece, a lower piece, and an annular surrounding band. Multiple partitions 200 divide the sealed air chamber 100 into multiple independent support air chambers 101; Multiple support members 300 are respectively disposed in each of the support air chambers 101, and the support members 300 and the support air chambers 101 are integrally formed; An inflation control module is disposed on the sealed air chamber 100 and is independently connected to each of the supporting air chambers 101. The inflation control module is provided with multiple inflation modes for independently inflating each of the supporting air chambers 101 under different inflation modes.

[0024] In this embodiment, the air mattress includes a sealed air chamber 100, a partition 200, a support member 300, and an inflation control module. The sealed air chamber 100 serves as the basic structure, forming a highly airtight cavity structure through a three-dimensional enclosure design of an upper piece, a lower piece, and an annular surrounding band. The partition 200 divides the sealed air chamber 100 into multiple independent support air chambers 101. The support frame is set inside the support air chambers 101, and the support air chambers 101 and the support member 300 are manufactured using an integrated molding process. The inflation control module serves as the core adjustment unit and is equipped with multiple inflation modes. Users can independently control the inflation of each support air chamber 101 according to various inflation modes, thereby meeting the differentiated support needs of different body parts.

[0025] This embodiment significantly improves the stability and durability of the air mattress after inflation by adopting an integrated support structure, completely eliminating the need for traditional cable-driven structures. Furthermore, the adjustable inflation control module enables various support modes. This air mattress also boasts significant advantages such as simple structure, low cost, high portability, and ease of operation.

[0026] It should also be noted that the inflatable mattress provided in this embodiment is particularly suitable for use in various outdoor and mobile environments such as camping and vehicle use. Whether setting up a tent for camping in a vast natural environment or in situations where the interior space of a vehicle is limited, the inflatable mattress provided in this embodiment demonstrates its unique applicability and convenience, bringing users a comfortable experience.

[0027] In one embodiment, five supporting air chambers 101 are provided, and the five supporting air chambers 101 correspond to the head region, shoulder and back region, waist region, hip region and foot region of the human body, respectively.

[0028] In this embodiment, the sealed air chamber 100 is divided into five independent support air chambers 101 by the partition 200. Each support air chamber 101 corresponds to a key part of the human body (i.e., the head area, shoulder and back area, waist area, hip area, and foot area) to form a precise support system. In practical applications, when the user lies down, the support air chamber 101 in the head area can provide soft support with lower air pressure, the support air chamber 101 in the shoulder and back area can maintain the natural curvature of the spine with medium air pressure, the support air chamber 101 in the waist area can strengthen support and prevent collapse with higher air pressure, the support air chamber 101 in the hip area can form a continuous support surface with the waist, and the support air chamber 101 in the foot area can promote blood circulation with moderate air pressure. This zoned air pressure design allows the mattress to automatically adjust the support intensity according to the weight distribution and physiological characteristics of different parts of the body. For example, when the user lies on their side, the air chambers corresponding to the shoulder and hip can automatically reduce the air pressure through the inflation control module to reduce local pressure concentration while maintaining the support stability of other areas, effectively solving the problem of spinal distortion caused by the "uniform softness and firmness" of traditional air mattresses.

[0029] Specifically, this embodiment employs a heat-sealing isolation process to partition the sealed air chamber 100. High-frequency heating fuses the upper and lower panels with the annular surrounding band at preset positions, forming a completely isolated independent air chamber structure. The width ranges corresponding to the five supporting air chambers 101 are 270-290mm, 350-370mm, 110-130mm, 470-490mm, and 750-760mm respectively, for example, 280mm, 360mm, 120mm, 480mm, and 760mm respectively.

[0030] In one embodiment, the support member 300 includes heat-sealed ribs.

[0031] Furthermore, the heat-sealed ribs are integrally formed with the supporting air chamber 101 by high-frequency heat sealing or ultrasonic welding.

[0032] This embodiment uses an integrated heat-sealed rib for support. The integrated heat-sealed rib is seamlessly connected to the inner wall of the support air chamber 101 through high-frequency heat sealing or ultrasonic welding. This process not only eliminates the risk of wire breakage in traditional wire drawing processes, but also avoids the potential for air leakage caused by multi-node welding.

[0033] The integrated heat-sealed ribs are arranged in a grid or wave pattern. The grid-shaped rib structure achieves uniform stress distribution through a crisscrossing support network, which is particularly suitable for large load-bearing areas such as the shoulders, back, and hips; the wave-shaped ribs conform to the curves of the human body through their arc-shaped support surfaces, forming flexible support in the head and waist areas and effectively dispersing peak pressure.

[0034] The heat-sealed ribs described in this embodiment are highly integrated with the mattress body, presenting a seamless and perfect unity. This design concept fundamentally eliminates the use of additional components such as separate welded pieces and traction lines commonly found in traditional mattress manufacturing, completely eliminating the inconvenience and potential problems caused by these extra parts. Through this innovative structural optimization, not only is the mattress manufacturing process simplified, but the overall stability and lifespan of the product are also significantly improved, bringing users a more comfortable and reassuring user experience.

[0035] In one embodiment, the inflation control module includes: The main inflation port is located on the sealed air chamber 100; An external air pump is connected to one end of the main air inlet. The control valve includes a valve body and a valve core. One end of the valve body is connected to the other end of the main air inlet. The valve body has multiple independent air passages inside, and the multiple independent air passages are connected to multiple supporting air chambers 101.

[0036] Furthermore, the valve core is provided with multiple layers of throttling channels that communicate with each of the supporting air chambers 101, and the air flow rate that can pass through each layer of throttling channels is different. The valve body is selectively connected to the multi-layered throttling channels.

[0037] The inflation control module described in this embodiment includes a main inflation port, an external air pump, and a control valve. One end of the main inflation port is connected to the external air pump, and the other end is connected to the control valve. The control valve includes a valve body and a valve core. The valve body has multiple independent air passages, each connected to a corresponding support air chamber 101, ensuring that each support air chamber 101 can be inflated independently. When the external air pump inflates through the main inflation port, the gas flows through the mechanical mode selection valve and is automatically distributed to the five support air chambers 101, achieving different final air pressures to achieve differentiated soft and hard support. The valve core, as the core component of the control valve, has multiple layers of throttling channels internally. These throttling channels are connected to each support air chamber 101, and each layer of throttling channels allows for a different airflow rate. By selectively connecting the valve body to different layers of throttling channels, the inflation speed and air pressure of each support air chamber 101 can be precisely controlled, thereby meeting the user's needs for differentiated support for different body parts. This design not only improves the adjustment precision of the air mattress, but also enhances its flexibility and comfort.

[0038] Specifically, the valve core can be a cylindrical structure with three layers of throttling channels inside. Each layer of throttling channels has five throttling orifices, and each layer of throttling orifices allows for a different airflow rate. Each layer of throttling channels corresponds to a different group of people, and the outer surface of the valve core fits tightly with the inner wall of the valve body. When the valve core rotates to a certain layer of throttling channels, the main air inlet is connected to the five air chamber inlet ports through the five throttling orifices of that layer.

[0039] In addition, the control valve also includes a control component, which is disposed on the outer surface of the sealing air chamber 100 and connected to the valve core, for controlling the state of the valve core.

[0040] The control component is located outside the sealed air chamber 100, allowing users to easily adjust the opening degree of the valve core and thus control the connectivity of each throttling channel. This design eliminates the need for complex operating procedures; users can achieve precise inflation control of different support air chambers 101 simply by adjusting the control component. The control component can be a rotary knob or a linear slider, among other structures.

[0041] Here, the control component is equipped with multiple inflation modes. By setting multiple inflation modes on the control component, users can directly select the support mode suitable for their needs without a complicated manual adjustment process. For example, three inflation modes can be set, including: Mode 1 - for small-sized people, Mode 2 - for medium-sized people, and Mode 3 - for large-sized people. With these three inflation modes, users can quickly select the appropriate mode based on their body size. When mode 1 is selected, the inflation control module automatically adjusts the air pressure of each support chamber 101 to provide suitable support for smaller individuals in the head, shoulders, back, waist, hips, and feet areas. The overall support is relatively soft and better conforms to the body curves of smaller individuals. When mode 2 is selected, the air pressure of each support chamber 101 is adjusted to a level suitable for medium-sized individuals, providing sufficient support while maintaining a certain level of softness and preserving the natural curvature of the spine. When mode 3 is selected, the inflation control module increases the air pressure of each support chamber 101, providing stronger support for larger individuals and preventing the mattress from sinking excessively due to excessive weight, ensuring that all parts of the body receive reasonable support. This multi-inflation mode setting greatly improves the applicability and convenience of the air mattress, meeting the needs of users of different body sizes.

[0042] Of course, in other embodiments, the control component can also be set to other inflation modes, such as standard mode, soft mode, and reinforced support mode, as well as customized modes for specific usage scenarios (such as camping, in-vehicle use, and rehabilitation care). Users can quickly switch modes simply by rotating the knob or sliding the switch. At this time, the control component will synchronously adjust the valve core position so that the air pressure of each support air chamber 101 automatically matches the preset value. For example, in soft mode, the air pressure in the head and foot air chambers is reduced by 20%, the air pressure in the shoulder and back is reduced by 10%, while the air pressure in the waist air chamber remains unchanged, forming a flexible support surface that conforms to the curve of the human body; in reinforced support mode, the air pressure in the waist air chamber is increased by 30%, the air pressure in the shoulder and back is increased by 15%, and the air pressure in the remaining air chambers is simultaneously fine-tuned to effectively distribute body pressure and prevent muscle fatigue caused by prolonged lying down. This intelligent inflation control design not only simplifies the operation process, but also significantly improves the adaptability and comfort of the mattress through precise air pressure adjustment, meeting the differentiated needs of different user groups (such as the elderly, pregnant women, and athletes).

[0043] Furthermore, the control valve also includes a valve disposed between the throttling channel and the support air chamber 101.

[0044] The valve allows for the opening and closing control of the supporting air chamber 101. Specifically, the valve can be a mechanical spring valve that automatically closes when no gas enters to prevent pressure leakage. After use, the inflation valve can be opened to release the gas. Once all gas has been released, the airbag can be folded and stored in the storage bag.

[0045] In practical applications, combined with Figure 3 When using the air mattress, the user first selects a mode by rotating the external knob. There are three modes: small, medium, and large. Based on the different modes, the throttling orifices on the corresponding throttling channels align with the five air passages. The air pump begins inflation according to the corresponding mode, and the airflow enters each support air chamber 101 according to the preset air pressure. When the air pump stops working, the valves at the connection points between the air chambers and the air passages close, and the air mattress forms its final support mode.
