Abstract
Description
Technical Field
[0001] This invention belongs to the field of plug-in interface technology, specifically relating to a quick-plug interface for an electric air mattress. Background Technology
[0002] Medical electric air mattresses are commonly used devices for the prevention and care of pressure ulcers in long-term bedridden patients. They are widely used in hospital wards, ICUs, rehabilitation centers, and home long-term care settings. The mattress can adjust the support pressure by periodically inflating and deflating the air, reducing the duration of pressure on the patient's local skin. The air inlet is the core component that connects the air pump to the air circuit of the mattress. Its ease of connection and sealing stability directly affect the efficiency of nursing operations and the effectiveness of mattress use.
[0003] Existing plug-in interfaces for medical air mattresses rely on static interference fit of the sealing ring to achieve a seal. In clinical practice, frequent plugging and unplugging of the interface is required due to mattress replacement and equipment disinfection. As the material passes through the inner wall of the sealing ring, wear is easily caused, and the sealing performance gradually decreases with the number of uses, resulting in a poorer sealing effect. At the same time, the locking force of ordinary plug-in structures is limited, and the connection can easily become loose due to the pulling of pipelines and the movement of equipment during nursing operations. In addition, the plug is prone to shaking, which affects the sealing effect. Therefore, a quick plug-in interface for electric air mattresses is proposed. Summary of the Invention
[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.
[0005] Given the following technical problems in the existing technology: frequent plugging and unplugging of the interface, wear is easily caused by the pipe passing through the inner wall of the sealing ring, the sealing performance gradually decreases with the number of uses, and the sealing effect deteriorates. At the same time, the locking force of ordinary plug-in structure is limited, and the connection can easily become loose due to pipeline pulling and equipment displacement during nursing operations. In addition, the plug is easy to shake, which affects the sealing effect.
[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a quick-plug interface for an electric air mattress, comprising, A male plug is connected to a female socket. Several external pipes are connected to the side of the male plug away from the female socket. Several air inlets are connected to the side of the female socket away from the male plug. An insertion shell is fixed to the inner wall of the male plug. A base plate is installed in the middle of the bottom of the insertion shell. An insertion seat is installed on the inner wall of the male plug. Several insertion holes are opened in the insertion seat. Fixing plates two are fixed to both sides of the short side of the inner wall of the female socket. Fixing plates one are installed on both sides of the long side of the inner wall of the male plug. The device includes a pair of locking strips, which are installed on both sides of the long side of the male plug. The long side of the female socket has slots on both sides, and the locking strips can be inserted into the female socket and locked into the slots. Tracheal sealing assembly, which is installed on the base plate, is used to seal the connecting air port; Side anti-loosening component, which is installed on the second fixing plate, is used to limit the insertion shell and ensure that the male plug does not loosen.
[0007] Furthermore, the air inlet is inserted into the corresponding insertion port, and the outer pipe is connected to the corresponding insertion port.
[0008] Furthermore, a notch is provided in the middle of the fixing plate, and the notch is adapted to the card strip.
[0009] Furthermore, the tracheal sealing assembly includes several mounting grooves, each of which is formed on a base plate and surrounds the air inlet. A mounting shell is installed in each mounting groove. A sealing ring is provided on the side of the mounting shell facing the air inlet. A limiting ring one is installed at the bottom of the insertion seat corresponding to the sealing ring. A limiting ring two, located inside the limiting ring one, is installed at the bottom of the insertion seat corresponding to the sealing ring. Sealing protrusions are installed on both the side of the sealing ring facing the air inlet and the side facing the insertion seat. A second air supply pipe is fixedly connected to the bottom of the mounting shell. A branch pipe is fixedly connected to the side of the air inlet. A socket is installed at the other end of each branch pipe. A compression ring one is installed in the socket. The end of the second air supply pipe facing the socket is inserted into the socket and fixedly connected to the compression ring two. An annular notch located outside the sealing protrusion is provided on the side of the sealing ring facing the air inlet.
[0010] Furthermore, a gap is formed between the first limiting ring and the second limiting ring, the sealing protrusion facing the insertion seat protrudes out of the gap, and the sealing protrusion facing the air inlet is set to protrude from the inner wall of the base plate.
[0011] Furthermore, an upper top ring is installed on the inner wall of the sealing ring, and a side top ring is installed on the side of the inner wall of the sealing ring near the air inlet. The side top ring is inclined on the side that is close to the upper top ring.
[0012] Furthermore, the side anti-loosening assembly includes four air supply pipes three, each connected to a corresponding branch pipe. Each air supply pipe three is connected to an air supply chamber on a fixed plate two. The air supply chamber is connected to an air chamber one on the fixed plate two. Two vertically distributed limiting strips are installed at the opening of the air chamber one. A sliding seat is slidably connected in the air chamber one, protruding between the two limiting strips. An air chamber two is opened in the sliding seat. A support is installed in the air chamber two. A spring one is connected between the sliding seat and the air chamber. A positioning rod is installed on the side of the support away from the spring one. A sliding plate is slidably connected to the positioning rod. A sliding sleeve is fixed to the side of the sliding plate away from the support. One end of a transmission rod is hinged to both the upper and lower sides of the sliding sleeve. A filling plate is hinged to the other end of the transmission rod. A through sliding opening matching the filling plate is opened on the sliding seat. A spring two, sleeved on the outside of the positioning rod, is installed between the support and the sliding plate.
[0013] Furthermore, the sliding seat has a connecting port that connects air chamber two and air chamber one.
[0014] Furthermore, a filling opening is provided on the wall of the insertion shell, and clearance openings are provided on both sides of the sliding seat.
[0015] Furthermore, the four gas supply pipes are divided into two groups and symmetrically arranged on both sides of several gas inlets. The several gas inlets are arranged in pairs, and each group of gas supply pipes is connected to one end of the branch pipe on two gas inlets in one of the two groups located on both sides of the several gas inlets.
[0016] The beneficial effects of this invention are as follows: 1. In the initial stage of insertion, the air inlet squeezes the sealing protrusion, which drives the side top ring and the upper top ring to cooperate. The two sealing protrusions are squeezed in both directions to fit tightly against the corresponding wall surface, thus forming a stable passive pre-seal. During the inflation operation, some gas is introduced into the sealing ring through the branch pipe, which pushes the sealing ring to expand and further press the sealing protrusions on both sides. This can automatically compensate for the sealing wear caused by multiple insertions and removals, and can maintain the bidirectional sealing effect at the air inlet insertion point even after long-term use.
[0017] 2. After the device is inserted into place, the locking strip engages with the slot to achieve initial fixation. During inflation, the air pressure can synchronously drive the side anti-loosening components to move. The sliding seat extends out of the insertion shell first, and then the filling plate opens and engages with the filling port to form a limit. The symmetrical arrangement of multiple anti-loosening structures ensures uniform force distribution, effectively preventing the male plug from shaking or coming out after insertion. After deflation, the device automatically resets and unlocks using springs one and two, allowing for quick insertion and removal without additional operation. Simultaneously, the difference in elasticity between springs one and two enables the sequential movement of the sliding seat and the filling plate. Overall, the operation is simple and the connection is reliable.

[0024] Reference Figures 1-6 This invention provides a quick-connect interface for an electric air mattress, comprising: A male plug 100 is connected to a female socket 200. Several external pipes 101 are connected to the side of the male plug 100 away from the female socket 200. Several air inlets 201 are connected to the side of the female socket 200 away from the male plug 100. An insertion shell 105 is fixedly connected to the inner wall of the male plug 100. A base plate 106 is installed in the middle of the bottom of the insertion shell 105. An insertion seat 102 is installed on the inner wall of the male plug 100. Several insertion holes 103 are opened in the insertion seat 102. Fixing plates 202 are fixedly connected to both sides of the short side of the inner wall of the female socket 200. Fixing plates 104 are installed on both sides of the long side of the inner wall of the male plug 100. A pair of locking strips 300 are provided. The locking strips 300 are installed on both sides of the long side of the male plug 100. The long side of the female socket 200 has slots 400 on both sides. The locking strips 300 can be inserted into the female socket 200 and then locked into the slots 400. Tracheal sealing assembly, which is installed on the base plate 106, is used to seal the connecting air port 201; Side anti-loosening component, the side anti-loosening component is installed on the fixing plate 202, used to limit the insertion shell 105 and ensure that the male plug 100 does not loosen; When in use, align the male plug 100 with the female socket 200 and insert it. The insertion shell 105 extends into the female socket 200 simultaneously with the male plug 100. The air inlet 201 is inserted into the insertion port 103 of the insertion seat 102 to achieve air connection. After insertion, the locking strips 300 on both sides of the male plug 100 are locked into the locking slots 400 on the side wall of the female socket 200 to complete the initial locking and fixation. In the inserted state, the air pipe sealing component seals the insertion gap of the air inlet 201 to prevent air leakage during inflation. The side anti-loosening component limits the insertion shell 105 during inflation to prevent the male plug 100 from shaking and falling out. After deflation, it automatically detaches from the insertion shell 105 to achieve quick insertion and removal and stable connection.
[0025] The air inlet 201 is inserted into the corresponding insertion port 103, and the outer tube 101 is connected to the corresponding insertion port 103. When the male plug 100 is plugged into the female socket 200, the air inlet 201 is aligned and inserted into the corresponding insertion port 103, so that the outer tube 101, the insertion port 103, and the air inlet 201 are connected in sequence to form a complete inflation air path, ensuring that gas can enter the air inlet 201 from the outer tube 101 through the insertion port 103, and complete the stable transmission of the inflation medium. The outer tube 101 is connected to an external air source, and the air inlet 201 is connected to the air mattress.
[0026] The fixing plate 104 has a notch 1041 in the middle. The notch 1041 is adapted to the locking strip 300. When the male plug 100 is inserted into the female socket 200, the locking strip 300 and the fixing plate 104 are inserted along the long side wall of the female socket 200. The notch 1041 provides space for the locking strip 300, ensuring that the locking strip 300 is accurately aligned with the locking slot 400 to complete the locking.
[0027] like Figure 2 , Figure 4As shown, in order to compensate for wear at the sealing point caused by insertion and removal and ensure the sealing effect, the tracheal sealing assembly includes several mounting grooves 501. These mounting grooves 501 are all formed on the base plate 106 and surround the air inlet 201. A mounting shell 502 is installed in each mounting groove 501. A sealing ring 503 is provided on the side of the mounting shell 502 facing the air inlet 201. A limiting ring 504 is installed at the bottom of the insertion seat 102 corresponding to the sealing ring 503. A limiting ring 505, located inside the limiting ring 504, is installed at the bottom of the insertion seat 102 corresponding to the sealing ring 503. The sealing ring 503 has a sealing ring on the side facing the air inlet 201 and a sealing ring 505 on the side facing the insertion seat 102. A sealing protrusion 507 is installed on one side of the mounting shell 502. A second air supply pipe 510 is fixedly connected to the bottom of the mounting shell 502. A branch pipe 509 is fixedly connected to the side of the air inlet 201. A socket 511 is installed at the other end of each branch pipe 509. A compression ring 5091 is installed in the socket 511. The end of the second air supply pipe 510 facing the socket 511 is inserted into the socket 511 and fixedly connected to the compression ring 5101. The sealing ring 503 has an annular notch 508 on the side facing the air inlet 201, located outside the sealing protrusion 507. After the male plug 100 is inserted into the position, the base plate 106 moves synchronously to the corresponding position with the insertion shell 105, and the air inlet 201 extends into the mounting shell 102 accordingly. In the inner area of slot 501, the second air supply pipe 510 at the bottom of housing 502 is simultaneously inserted into the socket 511 at the end of branch pipe 509. The compression ring 5091 inside socket 511 is tightly fitted with the compression ring 5101 at the end of the second air supply pipe 510, forming a gas passage seal in the insertion section. This is a direct sealing contact, and the wear between compression ring 5101 and compression ring 5091 is relatively small. When the air inlet 201 is inserted into the insertion port 103, it will first contact the sealing protrusion 507, forming a wall seal on the air inlet 201 to prevent air leakage. However, repeated insertion and removal of the male plug 100 will cause wear to the sealing protrusion 507 of the sealing ring 503, which will lead to long-term wear. Use will affect the sealing effect. Therefore, when the air inlet 201 is filled with gas, some gas will be introduced into the sealing ring 503 through the branch pipe 509 and the second air supply pipe 510. The air pressure pushes the sealing ring 503 to expand and deform towards the insertion seat 102. The limiting ring 504 and the limiting ring 505 at the bottom of the insertion seat 102 form a limit, which strengthens the protection of the sealing ring 503. After the sealing ring 503 expands, the sealing protrusions 507 on both sides of the sealing ring 503 will fit more tightly against the surface of the insertion seat 102 and the air inlet 201, realizing bidirectional sealing at the insertion point of the air inlet 201. This compensates for the wear of the sealing ring 503 caused by insertion and removal and ensures the fit, thus ensuring the sealing effect.
[0028] A gap is formed between the first limiting ring 504 and the second limiting ring 505. The sealing protrusion 507 facing the insertion seat 102 protrudes out of the gap, and the sealing protrusion 507 facing the air inlet 201 protrudes out of the inner wall of the base plate 106. When the sealing ring 503 expands under air pressure, the sealing protrusion 507 facing the insertion seat 102 gets into the gap formed by the first limiting ring 504 and the second limiting ring 505, forming a limit and preventing the sealing ring 503 from shifting due to air pressure. The sealing protrusion 507 facing the air inlet 201 protrudes out of the inner wall of the base plate 106 and can directly adhere to the circumferential outer wall of the air inlet 201 to form a radial seal and block the air passage from leaking from the insertion gap.
[0029] An upper top ring 5062 is installed on the inner wall of the sealing ring 503, and a side top ring 5061 is installed on the side of the inner wall of the sealing ring 503 near the air inlet 201. The side top ring 5061 is inclined on the side near the upper top ring 5062. When the air inlet 201 is inserted, it will first act on the sealing protrusion 507 facing the air inlet 201. The sealing protrusion 507 will shift inward, causing the side top ring 5061 to move towards the upper top ring 5062. The side top ring 5061 and the upper top ring 5062 then come into contact. The upper top ring 5062 restricts the movement of the side top ring 5061, thereby pressing the side top ring 5061 in the opposite direction and limiting the excessive offset of the side top ring 5061. The side top ring 5061 presses the sealing protrusion 507 facing the insertion seat 102 towards the bottom of the insertion seat 102. The upper top ring 5062, by pressing the side top ring 5061, presses the sealing protrusion 507 facing the air inlet 201 towards the wall of the air inlet 201, thereby ensuring that both sealing protrusions 507 can fit tightly against the corresponding wall surface and enhance the sealing effect.
[0030] like Figure 2 , Figure 5As shown, to prevent the male plug 100 from loosening after insertion, the side anti-loosening assembly includes four air supply pipes 601. Each of the four air supply pipes 601 is connected to a corresponding branch pipe 509. Each air supply pipe 601 is connected to an air supply chamber 603 located on the fixed plate 202. The air supply chamber 603 is connected to an air chamber 602 located on the fixed plate 202. Two vertically distributed limiting strips 606 are installed at the opening of the air chamber 602. A sliding seat 605 is slidably connected in the air chamber 602, protruding between the two limiting strips 606. An air chamber 6052 is formed in the sliding seat 605, and a support 607 is installed in the air chamber 605. A spring 604 connects the movable seat 605 and the air chamber 602. A positioning rod 611 is installed on the side of the support 607 away from the spring 604. A sliding plate 610 is slidably connected to the positioning rod 611. A sliding sleeve 612 is fixedly connected to the side of the sliding plate 610 away from the support 607. One end of a transmission rod 613 is hinged to both the upper and lower sides of the sliding sleeve 612. The other end of the transmission rod 613 is hinged to a filling plate 614. A through sliding port 615 matching the filling plate 614 is opened on the sliding seat 605. A spring 609, sleeved on the outside of the positioning rod 611, is installed between the support 607 and the sliding plate 610. When gas is filled into the air inlet 201, the air inlet 201... Figure 2 As a standard, the compressed gas in the four branch pipes 509 on the left and right sides is introduced into the air supply chamber 603 in the fixed plate 202 through the air supply pipe 3 601, and then delivered to the air chamber 1 602. The air pressure first acts on the end face of the sliding seat 605, pushing the sliding seat 605 to overcome the elastic force of the spring 1 604 and protrude outward along the gap between the two limiting strips 606, inserting into the inner wall of the insertion shell 105 to form a preliminary limit. Then the air pressure enters the air chamber 2 6052 in the sliding seat 605, acts on the surface of the sliding plate 610, and pushes the sliding plate 610 to overcome the elastic force of the spring 2 609 and slide outward along the positioning rod 611, driving the sliding sleeve 612 to move synchronously. The transmission rod 613, which is hinged at the top and bottom, opens the filling plate 614, so that the filling plate 614 extends outward along the sliding port 615 to the outside of the sliding seat 605, and presses against the inner wall of the insertion shell 105 to form a radial expansion limit, preventing the male plug 100 from shaking after insertion.
[0031] The sliding seat 605 has a connecting port 6051, which connects the second air chamber 6052 and the first air chamber 602. When the sliding seat 605 is in the initial contracted state, the elastic force of the first spring 604 is less than that of the second spring 609. Therefore, under the action of air pressure, the sliding seat 605 moves first. When the sliding seat 605 extends outward to the limiting bar 606 under the action of air pressure, the gas will act on the sliding plate 610. At this time, the second spring 609 is stretched, which opens the filling plate 614.
[0032] A filling opening 700 is provided on the wall of the insertion shell 105, and clearance openings 6053 are provided on both sides of the sliding seat 605. When the filling plate 614 is pushed outward by the transmission rod 613, the filling plate 614 is correspondingly inserted into the filling opening 700 on the wall of the insertion shell 105, forming a locking limit, which completely restricts the relative displacement between the male plug 100 and the female socket 200, and prevents the male plug 100 from coming out. The clearance openings 6053 are used to provide clearance space for the sliding seat 605, which facilitates insertion into the filling opening 700.
[0033] Four gas supply pipes 601 are symmetrically arranged in two groups on both sides of several gas inlets 201. The several gas inlets 201 are arranged in pairs, and each group of gas supply pipes 601 is connected to one end of the branch pipes 509 on two gas inlets 201 in one of the two groups located on both sides. The two groups of gas supply pipes 601 arranged symmetrically can be supplied with compressed gas simultaneously, which drives the sliding seats 605 and the filling plate 614 on both sides of the female socket 200 to move synchronously, so that the two sides of the insertion shell 105 are evenly stressed, avoiding the insertion deviation and jamming failure caused by the force on one side. Each group of gas supply pipes 601 takes gas from the branch pipes 509 of one group of gas inlets 201.
[0034] To ensure stable air pressure during use, an air pressure sensor can be installed in the sealing ring 503 and a solenoid valve can be installed at the connection between the branch pipe 509 and the air inlet 201. The solenoid valve and the air pressure sensor work together (not shown in the figure, but known to those skilled in the art). This way, when the air pressure reaches the set value, the passage of the branch pipe 509 can be closed, and then the passage of the branch pipe 509 can be opened when it is pulled out.
[0035] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine task in design, manufacturing, and production without requiring extensive experimentation.
[0036] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
