Description

Technical Field

[0001] This utility model relates to the field of pneumatic mattress technology, and in particular to a high-comfort pneumatic mattress. Background Technology

[0002] With the continuous development of science and technology, new materials and technologies are constantly emerging, providing more possibilities for the research and development of pneumatic mattresses. For example, the application of advanced air pump technology and intelligent control systems has significantly improved the comfort, convenience, and intelligence of pneumatic mattresses. Consumer upgrading and health awareness: As people's living standards improve and consumption concepts change, consumers have increasingly higher requirements for sleep quality. At the same time, increased health awareness is prompting people to pay more attention to their sleep environment and sleep quality. High-comfort pneumatic mattresses, with their unique comfort experience and health functions, meet the needs of modern consumers.

[0003] In existing technologies, traditional high-comfort pneumatic mattresses do indeed have a certain risk of air leakage due to their unique structural characteristics. Air leakage can not only affect the mattress's performance and reduce the user's sleep quality, but in severe cases, it can also cause the user to suddenly lose support during use, thus posing a safety hazard. Pneumatic mattresses are usually inflated by a built-in air pump or an external air source to maintain their shape and comfort. However, due to loose connections, material aging, wear and tear, etc., the mattress may leak air. Once air leakage occurs, the internal pressure of the mattress will gradually decrease, causing the mattress to soften, deform, or collapse, and it will no longer be able to provide stable support for the user. This will not only affect the user's sleeping posture and comfort, but may also cause the user to unconsciously change their sleeping position during sleep, thereby affecting sleep quality. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a highly comfortable pneumatic mattress.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a high-comfort pneumatic mattress, including a mattress base, an inflatable mattress detachably connected to the upper end of the mattress base, a sealing plate provided on the side end of the inflatable mattress, a fixed air tube fixed inside the inflatable mattress, a coupling tube threadedly connected inside the fixed air tube, a sliding air-closing valve sliding inside the coupling tube, air holes opened at both ends of the sliding air-closing valve, a connecting spring fixed at the bottom of the sliding air-closing valve, a limit base fixed at one end of the connecting spring, the outer surface of the limit base threadedly connected to the inner wall of the coupling tube, and an inflation hole opened at the bottom of the limit base.

[0006] Preferably, the mattress base has a fixed outer shell inside, a limiting inner rod is slidably connected inside the fixed outer shell, a cylinder is fixed at the bottom of the limiting inner rod, a sliding inner frame is slidably connected to the circumference of the limiting inner rod, a connector is rotatably connected to the surface of the sliding inner frame, a connecting bracket is rotatably connected to the surface of the connector, a fixing block is rotatably connected to the surface of the connecting bracket, and a cylinder is fixed at the bottom of the sliding inner frame. In the prior art, because the materials of pneumatic mattresses are usually relatively light and have a certain degree of elasticity, they may not be stable enough on the bed frame and are prone to moving or sliding. This instability not only affects the user's sleep quality but may also lead to a series of safety hazards. When the pneumatic mattress moves or slides on the bed frame, the user's sleeping posture may be affected, resulting in shallow sleep, frequent awakenings, or decreased sleep quality. In the long run, this may have adverse effects on the user's physical health and mental state. More seriously, if a user accidentally falls due to mattress displacement during use, it may lead to injury or even more serious consequences, especially for the elderly, children, or people with mobility impairments. To address this issue, this invention employs a fixed structure. The user aligns the bottom of the inflatable mattress with the fixed outer shell, then activates a cylinder to move the limiting inner rod upwards until it drags the sliding inner frame upwards to the top. The user then activates another cylinder to push the sliding inner frame upwards, causing it to push the fixing block out of the annular groove of the fixed outer shell via a connecting bracket. This secures the inflatable mattress to the mattress base, preventing slippage and improving the user's sleep quality and overall experience.

[0007] Preferably, the coupling tube is provided with a sealing ring on its circumference. The sealing ring on the circumference of the coupling tube can significantly improve the sealing performance of the entire system. This design can effectively prevent gas leakage, ensure stable internal pressure of the system, and thus improve overall working efficiency and safety.

[0008] Preferably, the connecting spring is a double-strand spring. Due to the structure of two springs connected in parallel, the double-strand spring can effectively distribute the force and improve the overall stability. Compared with a single-strand spring, the double-strand spring can better maintain its shape and position when subjected to external impact, thus reducing equipment vibration.

[0009] Preferably, the sliding inner frame is fixed with sliding keys at both ends. By using sliding keys, the direct metal contact between the inner frame and the outer frame can be reduced, thereby reducing the noise generated by friction.

[0010] Preferably, a dustproof sheet is fixed to the periphery of the sealing plate. By fixing the dustproof sheet to the periphery of the sealing plate, the frequency of internal cleaning and maintenance of the equipment can be reduced, maintenance costs can be reduced, work efficiency can be improved, and the risk of equipment damage caused by improper maintenance can be reduced.

[0011] Preferably, the mattress base has fixed feet at the bottom. The design of the fixed feet creates a distance between the bottom of the mattress and the ground, facilitating daily cleaning and maintenance. Users can more easily clean dust and debris from the bottom of the mattress, keeping it clean and hygienic.

[0012] Beneficial effects

[0013] 1. Currently, traditional high-comfort pneumatic mattresses, due to their unique structural characteristics, do indeed have a certain risk of air leakage. Air leakage can not only affect the mattress's performance and reduce sleep quality, but in severe cases, it can also cause the user to suddenly lose support, posing a safety hazard. Pneumatic mattresses typically use a built-in air pump or an external air source to inflate and maintain their shape and comfort. However, due to loose connections, material aging, and wear, air leakage may occur. Once leakage occurs, the internal pressure of the mattress gradually decreases, causing it to soften, deform, or collapse, failing to provide stable support. This not only affects the user's sleep... Sleep posture and comfort can also lead users to unconsciously change their sleeping position during sleep, thus affecting sleep quality. To address this issue, this invention employs a protective structure. When the operator inflates the mattress, the air is compressed within the coupling tube, pushing the sliding air-closing valve inward. Simultaneously, once the air hole extends beyond the coupling tube, air can enter the interior of the air mattress, inflating it. After inflation is complete, the user turns off the inflator. The internal air pressure of the air mattress then presses the sliding air-closing valve in another direction, and with the help of spring force, moves the air hole into the coupling tube for concealment. This prevents air leakage from the air mattress, reducing the risk of air leakage and maintaining its shape and comfort.

[0014] 2. In existing technologies, because the materials used in pneumatic mattresses are typically lightweight and elastic, they may not be stable enough on the bed frame and are prone to shifting or sliding. This instability not only affects the user's sleep quality but may also lead to a series of safety hazards. When the pneumatic mattress shifts or slides on the bed frame, the user's sleeping posture may be affected, resulting in shallow sleep, frequent awakenings, or decreased sleep quality. Over time, this may have adverse effects on the user's physical health and mental state. More seriously, if a user accidentally falls due to mattress displacement during use, it may lead to injury or even more serious consequences, especially for the elderly, children, or people with mobility impairments. To address this issue, this invention employs a fixed structure. The user aligns the bottom of the inflatable mattress with the fixed outer shell, then activates a cylinder to move the limiting inner rod upwards until it drags the sliding inner frame upwards to the top. The user then activates another cylinder to push the sliding inner frame upwards, causing it to push the fixing block out of the annular groove of the fixed outer shell via a connecting bracket. This secures the inflatable mattress to the mattress base, preventing slippage and improving the user's sleep quality and overall experience. Attached Figure Description

[0022] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0023] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific implementation examples:

[0025] Reference Figure 1-5 A high-comfort pneumatic mattress includes a mattress base 1, with an inflatable mattress 101 detachably connected to the upper end of the mattress base 1. A sealing plate 102 is provided on the side of the inflatable mattress 101. A fixed air tube 2 is fixed inside the inflatable mattress 101, and a coupling tube 201 is threadedly connected inside the fixed air tube 2. A sliding air-closing valve 202 slides inside the coupling tube 201. Air holes 203 are provided at both ends of the sliding air-closing valve 202. A connecting spring 204 is fixed to the bottom of the sliding air-closing valve 202, and a limit base 205 is fixed to one end of the connecting spring 204. The outer surface of the base 205 is threaded to the inner wall of the coupling tube 201. An inflation hole 206 is provided at the bottom of the limiting base 205. In existing technology, traditional high-comfort pneumatic mattresses, due to their unique structural characteristics, do indeed have a certain risk of air leakage. Air leakage can not only affect the mattress's performance and reduce the user's sleep quality, but in severe cases, it can also cause the user to suddenly lose support during use, thus posing a safety hazard. Pneumatic mattresses are usually inflated by a built-in air pump or an external air source to maintain their shape and comfort. However, due to loose connections, material aging, wear, etc., the mattress may leak air. Once air leakage occurs, the internal pressure of the mattress will gradually decrease, causing the mattress to soften, deform, or collapse, no longer providing stable support for the user. This not only affects the user's sleeping posture and comfort, but may also cause the user to unconsciously change their sleeping position during sleep, further affecting sleep quality. To address this problem, this utility model adopts a protective structure. When the operator inflates the mattress, the air is compressed within the coupling tube 201, thereby propelling the mattress... The sliding air-closing valve 202 is pushed inward, and when the air hole 203 passes the coupling tube 201, air can enter the air mattress 101 to inflate it. After inflation, the user turns off the air conditioner, and the air pressure inside the air mattress 101 presses the sliding air-closing valve 202, pushing it in the other direction. At the same time, with the help of the spring force, the air hole 203 is moved into the coupling tube 201 and hidden, thereby preventing the air mattress 101 from leaking air, thus reducing the risk of air leakage and maintaining its shape and comfort.

[0026] The mattress base 1 has a fixed outer shell 3 inside, and a limiting inner rod 301 is slidably connected inside the fixed outer shell 3. A cylinder is fixed at the bottom of the limiting inner rod 301. A sliding inner frame 302 is slidably connected to the periphery of the limiting inner rod 301. A connector 303 is rotatably connected to the surface of the sliding inner frame 302. A connecting bracket 304 is rotatably connected to the surface of the connector 303. A fixing block 305 is rotatably connected to the surface of the connecting bracket 304. A cylinder is fixed at the bottom of the sliding inner frame 302. A sealing ring is provided on the periphery of the coupling tube 201. The connecting spring 204 is a double spring. Sliding keys are fixed at both ends of the sliding inner frame 302. A dustproof sheet is fixed on the periphery of the sealing plate 102. A foot pad is fixed at the bottom of the mattress base 1.

[0027] The working principle of this utility model is as follows: When the operator inflates the mattress, the air volume is compressed in the coupling tube 201, which pushes the sliding air-closing valve 202 inward. At the same time, when the air hole 203 exceeds the coupling tube 201, the air can enter the interior of the air mattress 101, thus inflating it. After inflation is completed, the user turns off the inflator. At the same time, the air pressure inside the air mattress 101 presses the sliding air-closing valve 202, pushing it in another direction. Simultaneously, with the help of spring thrust, the air hole 203 is moved into the interior of the coupling tube 201 and hidden, thereby preventing the air mattress 101 from leaking air, thus reducing the risk of air leakage and maintaining its shape and comfort.
