Description

Technical Field

[0001] This utility model relates to the field of airbag mattress technology, specifically to an adjustable firmness structure for airbag mattresses. Background Technology

[0002] In the field of airbag mattress technology, traditional airbag mattresses often use a simple inflation or deflation method to adjust the firmness of the mattress. However, this method has many shortcomings, such as low adjustment precision, inconvenient operation, and the inability to monitor and display the air pressure inside the airbag in real time.

[0003] First, traditional air-cushion mattresses typically only allow for adjustments via an air pump or manual inflation / deflation. This method often only provides a rough adjustment of firmness, failing to achieve the precise results desired by users. Due to the lack of a fine adjustment mechanism, users often need to experiment repeatedly when adjusting the mattress firmness, which not only increases the difficulty of operation but also reduces the user experience.

[0004] Secondly, traditional airbag mattresses lack real-time air pressure monitoring and display during adjustment. Users cannot intuitively understand the air pressure inside the airbags and can only judge the firmness of the mattress based on subjective feelings. This method is not only inaccurate but also fails to meet users' needs for precise control over mattress firmness.

[0005] In view of this, we propose an adjustable firmness structure for airbag mattresses. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a firmness adjustment structure for an airbag mattress.

[0007] The technical solution of this utility model is:

[0008] The airbag mattress has an adjustable firmness structure, including a mounting plate. The mounting plate contains an air supply channel connected to an installation pipe via an air supply tube. The bottom of the installation pipe is connected to an air inlet pipe, on which an air pump and a solenoid valve are installed. The air supply channel within the mounting plate contains a shut-off mechanism and an adjustment mechanism. The shut-off mechanism includes a first baffle that can be quickly pressed down. The adjustment mechanism includes a second baffle that can be spirally pressed down. The adjustment mechanism includes a second support block fixed to the top of the mounting plate. An external stud is threaded onto the second support block, and an internal stud is threaded onto the external stud. The second baffle is fixed to the bottom of the internal stud. The air supply channel has two sealing grooves that respectively engage with the first and second baffles.

[0009] As a preferred technical solution, the mounting tube is equipped with an inner extension tube that communicates with the inside of the airbag, and a pressure sensor is installed inside the inner extension tube.

[0010] As a preferred technical solution, a pressure display screen is fixedly installed on the top of the mounting plate, and the pressure display screen is electrically connected to the pressure sensor.

[0011] As a preferred technical solution, when both the external stud and the internal stud are screwed to the bottom, the second baffle is tightly fitted with the inner wall of the sealing groove.

[0012] As a preferred technical solution, the stopping mechanism includes a first support block fixed to the top of the mounting plate, an insert shaft slidably mounted on the first support block, and a first baffle fixed to the bottom of the insert shaft.

[0013] As a preferred technical solution, a pressing head is integrally formed on the top of the insert shaft, and a spring is installed between the bottom of the pressing head and the top of the first support block, with the spring located on the outside of the insert shaft.

[0014] As a preferred technical solution, in the initial state of the spring, the second baffle is located above the sealing groove, and when the insert shaft is pressed, the first baffle is tightly fitted with the sealing groove.

[0015] As a preferred technical solution, the end of the gas supply pipe near the mounting plate is a threaded pipe, and a connector is rotatably installed at both ends of the gas supply channel, with one of the connectors being threadedly connected to the threaded pipe.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Please see Figures 1-4 This utility model provides a technical solution:

[0026] The firmness adjustment structure of the airbag mattress includes a mounting plate 1. The mounting plate 1 has an air supply channel 15. The air supply channel 15 is connected to a mounting pipe 3 through an air supply pipe 2. The bottom of the mounting pipe 3 is connected to an air inlet pipe 31. An air pump 32 and a solenoid valve 33 are installed on the air inlet pipe 31. The air supply channel 15 in the mounting plate 1 has a shut-off mechanism 12 and an adjustment mechanism 13. The shut-off mechanism 12 includes a first baffle 122 that can be quickly pressed down. The adjustment mechanism 13 includes a second baffle 133 that is spirally pressed down. The adjustment mechanism 13 includes a second support block 130 fixed to the top of the mounting plate 1. An external stud 131 is threaded on the second support block 130. An internal stud 132 is threaded on the external stud 131. The second baffle 133 is fixed to the bottom of the internal stud 132. The air supply channel 15 has two sealing grooves 14 that are respectively inserted and matched with the first baffle 122 and the second baffle 133. Firstly, the adjustment distance can be extended by the air supply pipe 2. Secondly, the adjustment mechanism 13 is set in the air supply channel 15. The adjustment mechanism 13 is composed of inner and outer studs 131, which can adjust the position of the second baffle 133 more precisely, thereby making the air pressure in the airbag more precisely adjusted. It is also equipped with a shut-off mechanism 12, which can immediately shut off the air supply channel 15 after adjustment.

[0027] In a preferred embodiment, the mounting tube 3 is equipped with an inner extension tube 30 that communicates with the inside of the airbag, and a pressure sensor 34 is installed inside the inner extension tube 30. By installing the pressure sensor 34 inside the inner extension tube 30, the air pressure inside the airbag can be monitored in real time, providing data support for accurately controlling the firmness of the airbag mattress.

[0028] In a preferred embodiment, a pressure display screen 10 is fixedly mounted on the top of the mounting plate 1, and the pressure display screen 10 is electrically connected to the pressure sensor 34. The pressure display screen 10 fixedly mounted on the top of the mounting plate 1 and electrically connected to the pressure sensor 34 can intuitively display the air pressure value inside the airbag, making it convenient for the user to adjust it as needed.

[0029] In a preferred embodiment, when both the outer stud 131 and the inner stud 132 are screwed to their lowest positions, the second baffle 133 fits tightly against the inner wall of the sealing groove 14. This tight fit ensures a complete seal of the gas delivery channel 15, improving the stability and reliability of the adjustment structure.

[0030] In a preferred embodiment, the shut-off mechanism 12 includes a first support block 120 fixed to the top of the mounting plate 1, a sliding insert shaft 121 mounted on the first support block 120, and a first baffle 122 fixed to the bottom of the insert shaft 121. The shut-off mechanism 12, including the first support block 120 and the sliding insert shaft 121, allows the first baffle 122 to be quickly pressed down, achieving rapid shut-off of the gas delivery channel 15 and further improving the flexibility and convenience of adjustment.

[0031] In a preferred embodiment, a pressing head is integrally formed coaxially on the top of the insert shaft 121. A spring 123 is installed between the bottom of the pressing head and the top of the first support block 120, with the spring 123 located on the outside of the insert shaft 121. The integrally formed pressing head and spring 123 on the top of the insert shaft 121 allow the user to easily press down and reset the first baffle 122 by pressing the pressing head, making the operation more intuitive and convenient.

[0032] In a preferred embodiment, in the initial state of the spring 123, the second baffle 133 is positioned above the sealing groove 14, and when the insert shaft 121 is pressed, the first baffle 122 is tightly fitted with the sealing groove 14. With the spring 123 initially in its original state, the second baffle 133 positioned above the sealing groove 14, and the insert shaft 121 pressed, the first baffle 122 tightly fitted with the sealing groove 14, this design ensures that the gas delivery channel 15 is open when no adjustment is needed, and can be quickly sealed when it needs to be shut off, improving the accuracy and response speed of adjustment.

[0033] In a preferred embodiment, the end of the gas supply pipe 2 near the mounting plate 1 is a threaded pipe 20, and a connector 11 is rotatably installed at both ends of the gas supply channel 15, with one connector 11 threadedly connected to the threaded pipe 20. This design, with the threaded pipe 20 near the mounting plate 1 and connectors 11 rotatably installed at both ends of the gas supply channel 15, makes the connection between the gas supply pipe 2 and the mounting plate 1 more secure and reliable, while also facilitating the disassembly and replacement of the gas supply pipe 2.

[0034] When using the softness and firmness adjustment structure of the airbag mattress of this utility model, first insert the inner extension tube 30 into the airbag mattress and fix it to the airbag mattress.

[0035] When adjusting the firmness of the airbag mattress, the user can first adjust the position of the second baffle 133 within the air passage 15 by rotating the outer stud 131 and the inner stud 132, according to their personal needs. Since the outer stud 131 and the inner stud 132 are connected by threads, their rotation can change the vertical position of the inner stud 132 (and the second baffle 133 fixed at its bottom). When the second baffle 133 moves downwards, it gradually obstructs the cross-section of the air passage 15, thereby reducing the airflow and making the airbag mattress firmer; conversely, when the second baffle 133 moves upwards, the cross-section of the air passage 15 gradually increases, and the airflow also increases, making the airbag mattress softer.

[0036] To achieve precise control over the firmness of the airbag mattress, an inner tube 30 communicating with the inside of the airbag is installed on the mounting tube 3, and a pressure sensor 34 is installed inside the inner tube 30. The pressure sensor 34 can monitor the air pressure inside the airbag in real time and transmit the data to the pressure display screen 10 on the top of the mounting plate 1 via an electrical connection. The user can determine the current firmness of the airbag mattress based on the value on the pressure display screen 10, and further adjust the position of the second baffle 133 accordingly to achieve the ideal firmness effect.

[0037] After adjustment, to maintain the stable firmness of the airbag mattress, the air supply channel 15 needs to be shut off using the shut-off mechanism 12. The shut-off mechanism 12 includes a first support block 120 and a sliding insert shaft 121, with a first baffle 122 fixed to the bottom of the insert shaft 121. When the user presses the pressing head at the top of the insert shaft 121, the insert shaft 121 moves downwards, causing the first baffle 122 to quickly press down and tightly fit against the sealing groove 14, thus quickly shutting off the air supply channel 15. Tightening the second baffle 133 downwards seals the air supply channel 15.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
