Description

TECHNICAL FIELD

[0001] The present application relates to the field of air pumps, in particular to an inflator and an inflatable deck chair. BACKGROUND

[0002] Small inflators are specially designed for some common inflators in daily life which do not have high requirements on air pressure, such as inflatable toys, inflatable beds, inflatable deck chairs, etc. Such inflators are small in size, easy to carry, simple and convenient to operate, and are deeply loved by consumers. However, these inflators generally only have inflating function and do not have controllable deflation function, which affects the use of inflatable products in some cases. For example, when the inflatable bed is fully inflated, if it is felt that the inflatable bed is a little hard, the inflatable bed needs to be able to controllably deflate a proper amount of air to improve the comfort of the inflatable bed. However, since the inflator does not have a controllable deflation function, it can only deflate through the deflation port provided on the inflatable product. The deflation port on the inflatable product is generally simply sealed with a sealing plug. Once the sealing plug is separated from the deflation port, a large amount of air in the inflatable product will quickly rush out of the deflation port, and it is difficult to achieve controllable deflation. Moreover, it is also difficult to insert the sealing plug back into the deflation port under the impact of strong air flow. Therefore, the current common method is to wait until the air flow rushing out of the deflation port is not so strong, then insert the sealing plug back into the deflation port, and then restart the inflator to supplement the air in the inflatable product to a proper amount, which is time-consuming and laborious, and is relatively troublesome. SUMMARY

[0003] In order to solve the problem that the current small inflator does not have a controllable deflation function and affects the use experience of the inflatable product, the present application provides an inflator and an inflatable deck chair.

[0005] By adopting the above technical scheme, the inflator has the functions of inflation and deflation, and the displacement of the second reciprocating mechanism can control the deflation speed, so that the controllable deflation function is realized, and the use requirements of the inflated product are met.

[0006] Preferably, the air inlet structure, the first air outlet structure and the first air exhaust structure are configured as a through hole or a hollow structure.

[0007] By adopting the above technical scheme, the gas circulation in the inflator is realized by the through hole or the hollow structure.

[0008] Preferably, the first reciprocating mechanism includes a sliding piece and an elastic element, the sliding piece is slidably connected with the first air outlet structure, the sealing piece is fixedly connected with the sliding piece, and the elastic element is connected with the sliding piece and the first air outlet structure at two ends of the elastic deformation direction. After the fan rotates to attract the gas outside the shell to pass through the air inlet structure and enter the shell, the gas inside the shell blows the sealing piece to move away from the first air outlet structure, and then drives the sliding piece to slide relative to the first air outlet structure to make the elastic element elastically deform. After the fan stops rotating, the elastically deformed elastic element drives the sliding piece to slide reversely relative to the first air outlet structure, and then drives the sealing piece to approach and block the first air outlet structure.

[0009] By adopting the above technical scheme, after the fan rotates to attract the gas outside the shell to pass through the air inlet structure and enter the shell, the gas inside the shell blows the sealing piece to move away from the first air outlet structure, and then drives the sliding piece to slide relative to the first air outlet structure to make the elastic element elastically deform. After the fan stops rotating, the elastically deformed elastic element drives the sliding piece to slide reversely relative to the first air outlet structure, and then drives the sealing piece to approach and block the first air outlet structure.

[0010] Preferably, when the first air outlet structure is a hollow structure, the sliding piece includes a connecting block, a sliding shaft fixedly connected with the connecting block, and a pair of sliding plates symmetrically arranged on both sides of the sliding shaft, and the sliding plate and the sliding shaft slide through the hollow structure. The elastic element is a spring, the spring is sleeved on the sliding shaft and abuts against the connecting block, and the spring and the sealing piece are located on both sides of the hollow structure.

[0011] By adopting the above technical scheme, the spring is used to realize the automatic reset of the sealing piece and the blocking of the first air outlet structure, and the hollow structure ensures the smooth sliding of the sliding piece.

[0014] Preferably, the reciprocating moving mechanism two includes a sliding member two and an elastic element two. The sliding member two is slidably connected to the exhaust structure one, and the sealing plate two is fixedly connected to the sliding member two. The two ends of the elastic element two in the elastic deformation direction are respectively connected to the sliding member two and the exhaust structure one. When an external force is applied to the sliding member two, the sliding member two slides relative to the exhaust structure one, causing the sealing plate two to move away from the exhaust structure one, and causing the elastic element two to undergo elastic deformation. After the external force disappears, the elastic element two that has undergone elastic deformation drives the sliding member two to slide in the opposite direction relative to the exhaust structure one, and then drives the sealing plate two to approach and block the exhaust structure one.

[0015] By adopting the above technical solution, an external force is applied to the sliding member 2, causing the sliding member 2 to slide relative to the exhaust structure 1, thereby moving the sealing plate 2 away from the exhaust structure 1 and causing the elastic element 2 to undergo elastic deformation. After the external force disappears, the elastic element 2, which has undergone elastic deformation, causes the sliding member 2 to slide in the opposite direction relative to the exhaust structure 1, and then causes the sealing plate 2 to approach and block the exhaust structure 1.

[0016] Preferably, the second sliding member includes a connecting rod and a sliding cylinder fixedly connected to one end of the connecting rod. The sliding cylinder slides through the first exhaust structure and is fixedly connected to the second sealing sheet. The second elastic element is a second spring, which is sleeved on the slide cylinder and abuts against the end of the slide cylinder away from the second sealing plate. The second spring and the second sealing plate are located on both sides of the exhaust structure. The other end of the connecting rod extends out of the housing.

[0020] Preferably, the inflation device further includes a box body, one end of which is configured as an open opening to allow the outer shell to enter and exit the box body, and the air intake structure faces the open opening; The box body is constructed with an exhaust structure two facing the exhaust structure one and an exhaust structure two facing the exhaust structure one. The sealing sheet one and the sealing sheet two are located outside the box body, and the reciprocating moving mechanism one and the reciprocating moving mechanism two are located inside the box body.

The reciprocating moving mechanism two is used to move the sealing sheet two closer to or away from the exhaust structure two, and the sealing sheet two can block the exhaust structure two when it is close to the exhaust structure two.

[0021] By adopting the above technical solution, a box is installed on the outside of the outer shell. After the box is installed and fixed on the inflatable product, the outer shell can be separated from the box when the inflatable device is not in use, which facilitates the maintenance, repair and carrying of the inflatable device.

[0022] Preferably, the second air outlet structure and the second exhaust structure are constructed as a second through hole or a second hollow structure.

[0023] By adopting the above technical solution, airflow can be achieved inside and outside the box through the second through hole or the second hollow structure.

[0024] Preferably, the reciprocating moving mechanism includes a sliding member and an elastic element. The sliding member is slidably connected to the air outlet structure, and the sealing plate is fixedly connected to the sliding member. The two ends of the elastic element are connected to the sliding member and the air outlet structure, respectively. After the fan rotates, it draws gas from outside the housing through the air inlet structure into the housing. The gas inside the housing then passes through the air outlet structure and the air outlet structure, blowing the sealing plate away from the air outlet structure. This causes the sliding member to slide relative to the air outlet structure, resulting in elastic deformation of the elastic element. After the fan stops rotating, the elastic element, which has undergone elastic deformation, causes the sliding member to slide in the opposite direction relative to the air outlet structure, which in turn causes the sealing plate to approach and block the air outlet structure.

[0025] By adopting the above technical solution, after the fan rotates and attracts the gas outside the shell to enter the shell through the air intake structure, the gas inside the shell passes through the first air outlet structure and the second air outlet structure in sequence, blowing the sealing plate 1 away from the second air outlet structure. Then, it drives the sliding member 1 to slide relative to the second air outlet structure, causing the elastic element 1 to undergo elastic deformation. After the fan stops rotating, the elastic element 1, which has undergone elastic deformation, drives the sliding member 1 to slide in the opposite direction relative to the second air outlet structure, and then drives the sealing plate 1 to approach and block the second air outlet structure.

[0026] Preferably, when the second air outlet structure is a hollow structure, the first sliding member includes a connecting block, a sliding shaft fixedly connected to the connecting block, and a pair of sliding plates. The pair of sliding plates are symmetrically arranged on both sides of the sliding shaft, and the sliding plates and the sliding shaft slide through the hollow structure. The elastic element is a spring, which is sleeved on the sliding shaft and abuts against the connecting block. The spring is located inside the box.

[0027] By adopting the above technical solution, the sealing sheet is automatically reset and the air outlet is blocked by the spring, and the hollow structure ensures the smooth sliding of the sliding component.

[0028] Preferably, the sealing sheet one is fixedly connected to the sliding member one via a mounting base, and the mounting base and the sealing sheet one are located on the same side of the hollow structure two.

[0029] By adopting the above technical solution, the sealing sheet 1 is fixed by the mounting base, so that the sealing sheet 1 can reliably, stably and permanently block the gas outlet structure 2, and the sealing effect is excellent.

[0030] Preferably, the reciprocating moving mechanism two includes a sliding member two and an elastic element two. The sliding member two is slidably connected to the exhaust structure one and the exhaust structure two. The sealing plate two is fixedly connected to the sliding member two. The two ends of the elastic element two in the direction of elastic deformation are respectively connected to the sliding member two and the exhaust structure one. When an external force is applied to the sliding member two, the sliding member two slides relative to the exhaust structure two, causing the sealing plate two to move away from the exhaust structure two, and causing the elastic element two to undergo elastic deformation. After the external force disappears, the elastic element two that has undergone elastic deformation drives the sliding member two to slide in the opposite direction relative to the exhaust structure two, and then drives the sealing plate two to approach and block the exhaust structure two.

[0031] By adopting the above technical solution, an external force is applied to the sliding member 2, causing the sliding member 2 to slide relative to the exhaust structure 2, thereby moving the sealing plate 2 away from the exhaust structure 2 and causing the elastic element 2 to undergo elastic deformation. After the external force disappears, the elastic element 2, which has undergone elastic deformation, causes the sliding member 2 to slide in the opposite direction relative to the exhaust structure 2, thereby causing the sealing plate 2 to approach and block the exhaust structure 2.

[0032] Preferably, the second sliding member includes a connecting rod and a sliding cylinder fixedly connected to one end of the connecting rod. The sliding cylinder slides through the first exhaust structure and the second exhaust structure and is fixedly connected to the second sealing sheet. The sliding cylinder can slide relative to the second exhaust structure and separate from the second exhaust structure. The second elastic element is a second spring, which is sleeved on the slide cylinder and abuts against the end of the slide cylinder away from the second sealing piece. The second spring is located inside the outer shell. The other end of the connecting rod extends from the outer casing at the opening.

[0033] By adopting the above technical solution, the sealing sheet 2 is automatically reset and the exhaust structure 2 is blocked by the spring 2, while the external force is applied to the sliding part 2 by means of the connecting rod.

[0034] In addition, this application also proposes an inflatable recliner, including a carrier and an airbag connected to each other. The airbag is configured to surround the lower surface edge of the carrier, thereby defining a cavity on the lower surface of the carrier. The airbag is provided with an inflation device as described above, through which air is inflated into the airbag and gas is expelled from the airbag.

[0035] By adopting the above technical solution, the deflation of the inflatable recliner can be controlled, making it convenient to use.

Detailed Implementation

[0057] The following is in conjunction with the appendix Figures 1-15 This application will be described in further detail.

[0058] Example 1: This embodiment discloses an inflation device 5, which includes: a housing, a fan 55, a drive component 54, a first reciprocating movement mechanism and a first sealing plate 59, an inflation mechanism 56, and an inflation box 4. The inflation mechanism 56 includes a second reciprocating movement mechanism and a second sealing plate 566. Figure 1 and Figure 2As shown, the outer casing includes a housing 50 and a front cover 51 and a rear cover 52 that are detachably and fixedly installed at both ends of the housing 50. This design facilitates the assembly and disassembly of components located inside the housing. Of course, in other embodiments, one of the front cover 51 and the rear cover 52 can be detachably and fixedly connected to the housing 50, while the other is integrally formed with the housing 50. Alternatively, both the front cover 51 and the rear cover 52 can be integrally formed with the housing 50. Then, a doorway is provided on the housing 50 for installing components inside the housing 50.

[0059] In this embodiment, the outer shell is constructed with an air inlet structure, an air outlet structure 8, and an exhaust structure 9. The air inlet structure is used for external gas to enter the outer shell, the air outlet structure 8 is used for gas to flow out of the outer shell, and the exhaust structure 9 is also used for external gas to enter the outer shell. However, when the external environment connected to the air outlet structure 8 and the exhaust structure 9 is the interior of the inflatable product, the gas inside the inflatable product enters the outer shell through the exhaust structure 9 and is then discharged from the air inlet structure. The gas flowing out of the air outlet structure 8 enters the interior of the inflatable product.

[0060] Specifically, such as Figures 1-4 As shown, the air intake structure is located on the front cover 51, and the air outlet structure 8 and the exhaust structure 9 are located on the rear cover 52. This design facilitates the connection between the air outlet structure 8 and the exhaust structure 9 and the interior of the inflatable product, and the air intake structure is not easily blocked by the inflatable product, thus affecting the air intake and exhaust. It also makes it easier to press the connecting rod 561.

[0061] In this embodiment, the air intake structure, air outlet structure 8, and exhaust structure 9 are constructed as through holes or hollow structures, for example... Figure 1 The air intake structure shown is a hollow structure one, which is constructed as an air intake and exhaust grille 511.

[0062] In this embodiment, as Figure 3 and Figure 4 As shown, the fan 55 is rotatably installed inside the housing and close to the air intake structure. The rotation of the fan 55 draws air from outside the housing through the air intake structure into the housing. The drive unit 54 is connected to the fan 55 and is used to drive the fan 55 to rotate. Commonly, the drive unit 54 is a motor.

[0063] In this embodiment, as Figures 9-13 As shown, the air box 4 includes a box body 41, one end of which is open to allow the outer shell to enter and exit the box body 41. The air intake structure faces the open to avoid affecting the air intake and exhaust.

[0064] In this embodiment, the box body 41 is constructed with a second vent structure facing the first vent structure 8 and a second exhaust structure facing the first exhaust structure 9. This design allows gas inside the outer shell to flow out through the first vent structure 8 and then smoothly through the second vent structure to exit the inflation box 4. Similarly, gas outside the inflation box 4 can pass through the second exhaust structure to enter the inflation box 4 and then smoothly through the first exhaust structure 9 into the outer shell, before being discharged from the inlet structure. When the first vent structure 8 and the first exhaust structure 9 are located on the rear cover 52, the second vent structure and the second exhaust structure are located at the bottom of the box body 41. Furthermore, the second vent structure and the second exhaust structure are constructed as a through hole or a hollow structure, for example... Figures 11-13 As shown, both the second air outlet structure and the second exhaust structure are hollow structures. The second air outlet structure is constructed with a hollow surface 40, and the second exhaust structure is constructed with a hollow surface 49.

[0065] In this embodiment, as Figure 10 As shown, the sealing sheet 59 and the sealing sheet 566 are located outside the housing 41, and the reciprocating moving mechanism 1 and the reciprocating moving mechanism 2 are located inside the housing 41. The reciprocating moving mechanism 1 is used to move the sealing sheet 59 closer to or away from the exhaust structure 2, and the sealing sheet 59 can block the exhaust structure 2 after it approaches the exhaust structure 2. The reciprocating moving mechanism 2 is used to move the sealing sheet 566 closer to or away from the exhaust structure 2, and the sealing sheet 566 can block the exhaust structure 2 after it approaches the exhaust structure 2.

[0066] Specifically, the reciprocating movement mechanism includes a sliding member 57 and an elastic element. The sliding member 57 is slidably connected to the air outlet structure, and the sealing plate 59 is fixedly connected to the sliding member 57. The two ends of the elastic element are connected to the sliding member 57 and the air outlet structure, respectively. After the fan 55 rotates, it draws gas from outside the housing through the air inlet structure into the housing. The gas inside the housing then passes through the air outlet structure and the air outlet structure, blowing the sealing plate 59 away from the air outlet structure. This causes the sliding member 57 to slide relative to the air outlet structure, resulting in elastic deformation of the elastic element. After the fan 55 stops rotating, the elastic element, having undergone elastic deformation, causes the sliding member 57 to slide in the opposite direction relative to the air outlet structure, which in turn causes the sealing plate 59 to approach and block the air outlet structure. Of course, in other embodiments, the reciprocating movement mechanism and the reciprocating movement mechanism can also be conventional linear actuators such as cylinders, hydraulic cylinders, or linear motors.

[0067] In this embodiment, when the second air outlet structure is a hollow surface 40, such as Figure 12 As shown, the perforated surface 40 is constructed with a first insertion hole 45, a second insertion hole 46, and a vent 47. Airflow passes through the vent 47 and penetrates the perforated surface 40. Preferably, as shown... Figure 2 , Figure 4 , Figure 6, Figure 10 , Figure 11 As shown, the sliding element 57 includes a connecting block 571, a sliding shaft 573 fixedly connected to the connecting block 571, and a pair of sliding plates 572. The pair of sliding plates 572 are symmetrically arranged on both sides of the sliding shaft 573. The sliding plates 572 slide through the insertion hole 45, and the sliding shaft 573 slides through the insertion hole 46. The elastic element is a spring 574, which is sleeved on the sliding shaft 573 and abuts against the connecting block 571 and the hollow surface 40. The spring 574 is located inside the box 41. The sealing plate 59 is connected to the sliding shaft 573 and / or the sliding plate 572. When the sealing plate 59 moves away from the hollow surface 40, it causes the sliding element 57 to compress the spring 574. After the fan 55 stops rotating, the compressed spring 574 pushes the sealing plate 59 to automatically reset and seal the hollow surface 40. The hollow surface 40 facilitates the sliding element 57 to compress the spring 574 and the sliding element 57 to slide smoothly.

[0068] To further improve the sliding smoothness of the sliding component 57 and ensure that the sealing plate 59 reliably returns to its original position to seal the perforated surface 40, such as... Figures 11-13 As shown, the bottom of the box body 41 has an outwardly protruding part 44 that protrudes outward in a direction away from the box body 41. The hollow surface 40 is located on the outwardly protruding part 44. The design of the outwardly protruding part 44 increases the sliding contact area between the slider 57 and the box body 41, thereby improving the sliding stability of the slider 57.

[0069] Furthermore, such as Figure 6 As shown, the sealing sheet 59 is fixedly connected to the sliding member 57 via the mounting base 58. The mounting base 58 and the sealing sheet 59 are located on the same side of the hollow structure. The mounting base 58 includes: a seat body 581, at least one pair of limiting blocks 582, and a collar 583. The seat body 581 is fixedly connected to the sealing sheet 59. Preferably, the seat body 581 and the sealing sheet 59 are detachably fixedly connected. One specific form of detachable fixed connection is as follows: Figure 6As shown, the sealing sheet 59 is detachably and fixedly connected to the insert block 591. The insert block 591 passes through the seat body 581 and is fixedly connected to the sealing sheet 59, making the sealing sheet 59 fit tightly against the seat body 581. The limiting block 582 is fixedly connected to the seat body 581. The pair of limiting blocks 582 are spaced apart so that at least a part of the sliding plate 572 can be inserted between the pair of limiting blocks 582, facilitating the quick assembly of the mounting base 58 and the sliding member 57. The sliding plate 572 is assembled and positioned by the pair of limiting blocks 582. The collar 583 is fixedly connected to the seat body 581, and the sliding shaft 573 is inserted and fixedly connected to the collar 583. The sealing sheet 59 is soft and usually made of rubber. In order for the sealing sheet 59 to better seal the hollow surface 40, the mounting base 58 can be used to support and fix the sealing sheet 59, thereby facilitating the reliable, stable, and long-lasting sealing of the vent structure 2 by the sealing sheet 59 and improving the sealing effect.

[0070] In this embodiment, the vent structure 8 is further constructed as a hollow surface 524, and a portion of the rear cover 52 is recessed into the outer shell, thereby creating an indentation 521 on the rear cover 52, such as... Figure 3 and Figure 5 As shown, the hollow surface 524 is set on the recessed portion 521. This design facilitates the placement of the sliding member 57 in the recessed portion 521, making the installation of the sliding member 57 convenient and resulting in a compact overall structure of the inflation device 5. Furthermore, to facilitate quick and precise placement of the sliding member 57 in a designated position within the recessed portion 521, such as... Figure 5 As shown, a second cylindrical body 525 is provided in the recessed portion 521, which limits the installation of the connecting block 571. Figure 4 As shown, the hollowed-out surface 3 524 facilitates the installation of cylinder 2 525.

[0071] In this embodiment, further, such as Figure 5 As shown, the outer surface of the rear cover 52 is provided with a connecting ring 526, which is configured to be sleeved on the vent structure 8, as... Figure 13 As shown, the inner bottom surface of the box 41 is provided with a slot 48 for the connecting ring 526. When the outer shell is inserted into the inflation box 4, the connecting ring 526 is inserted into the slot 48. This design can improve the connection and sealing between the back cover 52 and the box 41 and reduce gas leakage through the first and second air outlet structures.

[0072] Specifically, the reciprocating moving mechanism two includes a sliding member two and an elastic element two. The sliding member two is slidably connected to the exhaust structure one 9 and the exhaust structure two. The sealing plate two 566 is fixedly connected to the sliding member two. The two ends of the elastic element two in the elastic deformation direction are respectively connected to the sliding member two and the exhaust structure one 9. When an external force is applied to the sliding member two, the sliding member two slides relative to the exhaust structure two, causing the sealing plate two 566 to move away from the exhaust structure two, and causing the elastic element two to undergo elastic deformation. After the external force disappears, the elastic element two that has undergone elastic deformation drives the sliding member two to slide in the opposite direction relative to the exhaust structure two, and then drives the sealing plate two 566 to approach and block the exhaust structure two.

[0073] In this embodiment, when the exhaust structure 9 is a through hole 1 and the exhaust structure 2 is constructed as a hollow surface 49, such as Figure 12 and Figure 13 As shown, the hollow surface 49 has a third insertion hole 491 and a fourth insertion hole 492. Preferably, as shown... Figures 2-4 , Figures 7-8 , Figure 11 As shown, the second sliding member includes a connecting rod 561 and a sliding cylinder 563 fixedly connected to one end of the connecting rod 561. The sliding cylinder 563 slides through the first through hole and the fourth insertion hole 492, and there is a gap between the sliding cylinder 563 and the first through hole and the fourth insertion hole 492 to facilitate airflow through the first through hole and the fourth insertion hole 492. Preferably, one end of the sliding cylinder 563 is connected to the connecting rod 561, and the other end passes through the first exhaust structure 9 and the second exhaust structure and is fixedly connected to the second sealing plate 566. The sliding cylinder 563 can slide relative to the second exhaust structure and separate from the second exhaust structure. With this design, even if the sliding cylinder 563 and the first exhaust structure 9 are set as non-removable structures, it will not affect the separation of the outer shell and the inflation box 4. The second elastic element is a second spring 565, which is sleeved on the slide cylinder 563 and abuts against the end of the slide cylinder 563 away from the sealing plate 566. The second spring 565 is located inside the outer shell, and the other end of the second spring 565 abuts against the hollow surface 49. Therefore, axial movement of the slide cylinder 563 can compress the second spring 565. Figure 3 As shown, the other end of the connecting rod 561 extends from the open outer shell. This design allows pressing the other end of the connecting rod 561 to push the slide cylinder 563 axially, thereby moving the sealing plate 566 away from the perforated surface 49 and simultaneously compressing the spring 565. At this time, the gas outside the inflation box 4 passes through the perforated surface 49 and the through hole 1 before entering the outer shell and then exiting through the air intake structure. Releasing the pressure on the connecting rod 561 causes the compressed spring 565 to push the slide cylinder 563 to move in the opposite direction and reset, causing the sealing plate 566 to seal the perforated surface 49. Thus, the spring 565 enables the sealing plate 566 to automatically reset and seal the exhaust structure, while not affecting the application of external force to the sliding member via the connecting rod 561.

[0074] In this embodiment, to facilitate pressing the other end of the connecting rod 561, such as Figure 7 As shown, the other end of the connecting rod 561 is connected to a vent button 562, which is mounted on the front cover 51. Figure 3 As shown.

[0075] In this embodiment, further, to improve the axial movement stability of the slide 563, such as... Figure 3 and Figure 5 As shown, a cylindrical body 522 is inserted and fixed in the through hole, and a sliding cylinder 563 passes through the cylindrical body 522 and is axially slidably connected to the cylindrical body 522. There is a gap between the sliding cylinder 563 and the cylindrical body 522, which does not affect airflow. The arrangement of the cylindrical body 522 increases the sliding contact area between the sliding cylinder 563 and the outer shell, which helps to improve the axial movement stability of the sliding cylinder 563. Furthermore, as... Figure 5 As shown, a slider 523 is provided on the inner wall of the cylindrical body 522, such as... Figure 7 and Figure 8 As shown, the outer circumferential surface of the sliding cylinder 563 is constructed with a sliding groove 564, such as... Figure 4 As shown, the slider 523 is located in the slide groove 564 and is slidably connected to the slide groove 564. The arrangement of the slider 523 and the slide groove 564 further improves the axial movement stability of the slide cylinder 563, ensuring that the sealing sheet 566 can reliably and effectively seal the exhaust structure 2 after reciprocating sliding, resulting in a good sealing effect.

[0076] In this embodiment, as Figure 7 and Figure 8 As shown, the end of the slide cylinder 563 near the sealing sheet 566 is provided with a receiving groove 567 to receive the hollow surface 49, so that the end of the slide cylinder 563 near the sealing sheet 566 can slide through the insertion hole 492, and the slide cylinder 563 can also be separated from the hollow surface 49.

[0077] In this embodiment, as Figure 8 As shown, the slide cylinder 563 has an insertion hole 569 at one end near the sealing sheet 2 566. The sealing sheet 2 566 is fixedly connected to an insertion block 1 568. One end of the insertion block 1 568 passes through the insertion hole 3 491 and is then inserted into the insertion hole 569, so that the slide cylinder 563 and the sealing sheet 2 566 are fixedly connected by the insertion block 1 568.

[0078] In this embodiment, further, to improve the sliding smoothness of the slide cylinder 563 and ensure that the sealing sheet 566 reliably resets to seal the perforated surface 49, as follows: Figures 11-13As shown, the bottom of the box body 41 has an outward protrusion 43 that protrudes outward in a direction away from the box body 41 and also protrudes inward in the box body 41. The hollow surface 49 is located on the outward protrusion 43. The design of the outward protrusion 43 increases the sliding contact area between the slide cylinder 563 and the box body 41, and improves the sliding stability of the slide cylinder 563.

[0079] In this embodiment, the inflation device 5 has a box 41 fitted over the outer shell. After the box 41 is installed and fixed onto the inflatable product, the outer shell can be separated from the box 41 when the inflation device 5 is not in use, which facilitates the maintenance, repair and carrying of the inflation device 5. Moreover, the inflation device 5 not only has inflation and deflation functions, but also controls the deflation speed by controlling the displacement of the reciprocating moving mechanism 2, thereby achieving a controllable deflation function and meeting the usage requirements of the inflatable product.

[0080] In this embodiment, when using the inflation device 5, the box 41 must first be sealed and fixedly installed onto the inflatable product. The external areas of the box 41 at the second air outlet structure and the second air outlet structure are located inside the inflatable product, while the open end of the box 41 is located outside the inflatable product. When the inflatable product is an inflatable recliner, such as... Figure 15 and Figure 14 As shown, only the open end of the air box 4 is exposed, while most of the rest is located inside the inflatable recliner. With this design, the gas discharged from the second air outlet structure can smoothly enter the inflatable product, and the gas inside the inflatable product can smoothly enter the outer shell through the second air outlet structure and the first air outlet structure 9.

[0081] In this embodiment, as Figure 9 and Figure 10 As shown, the open end of the box body 41 is also provided with a folded edge 42, which facilitates the sealing and bonding of the inflatable box 4 with the inflatable product.

[0082] In this embodiment, further, such as Figure 3 and Figure 4 As shown, a battery 53 is installed inside the outer casing. The battery 53 powers the drive unit 54, enabling the inflation device 5 to have its own power source. It does not require external mains power during operation, making it easy to carry. Furthermore, as... Figure 1 As shown, the front cover 51 is also provided with a charging interface 512 for charging the battery 53, an inflation switch 513 for controlling the start and stop of the drive unit 54, and a handle 514 for easy removal of the outer shell from the inflation box 4.

[0083] Example 2: The difference between this embodiment and Embodiment 1 is that the inflation device 5 does not have an inflation box 4. In this case, the outer shell is sealed to the inflatable product, and the outer areas of the outer shell at the air outlet structure 8 and the air exhaust structure 9 are located inside the inflatable product, while the air inlet structure is located outside the inflatable product. The sealing plate 59 is located next to the air outlet structure 8. The reciprocating moving mechanism 1 is used to move the sealing plate 59 closer to or away from the air outlet structure 8, and the sealing plate 59 can block the air outlet structure 8 after it approaches it. The sealing plate 566 is set... Located next to the exhaust structure 9 and connected to the reciprocating moving mechanism 2, the reciprocating moving mechanism 2 is used to move the sealing plate 2 566 closer to or away from the exhaust structure 9, and the sealing plate 2 566 can block the exhaust structure 9 after it approaches the exhaust structure 9. The structures of the reciprocating moving mechanism 1 and the reciprocating moving mechanism 2 are the same as or similar to the reciprocating moving mechanism 1 and the reciprocating moving mechanism 2 in Embodiment 1. The difference is that the sliding member 57 of the reciprocating moving mechanism 1 is slidably connected to the exhaust structure 8, and the sliding cylinder 563 is only slidably connected to the exhaust structure 9.

[0084] The inflation device 5 in this embodiment not only has inflation and deflation functions, but also controls the deflation speed by controlling the displacement of the reciprocating moving mechanism 2, thereby achieving controllable deflation function and meeting the needs of inflatable products. At the same time, the inflation box 4 is eliminated, reducing costs and avoiding the risk of loss during the transfer of the outer shell after it is separated from the box 41.

[0085] Specifically, the reciprocating movement mechanism in this embodiment includes a sliding member 57 and an elastic element. The sliding member 57 is slidably connected to the air outlet structure 8, and the sealing plate 59 is fixedly connected to the sliding member 57. The two ends of the elastic element in the direction of elastic deformation are respectively connected to the sliding member 57 and the air outlet structure 8. After the fan 55 rotates and attracts the gas outside the shell to pass through the air inlet structure and enter the shell, the gas inside the shell blows the sealing plate 59 away from the air outlet structure 8, which in turn drives the sliding member 57 to slide relative to the air outlet structure 8, causing the elastic element to undergo elastic deformation. After the fan 55 stops rotating, the elastic element that has undergone elastic deformation drives the sliding member 57 to slide in the opposite direction relative to the air outlet structure 8, which in turn drives the sealing plate 59 to approach and block the air outlet structure 8.

[0086] Specifically, when the air outlet structure 8 is a hollow structure, the sliding member 57 includes a connecting block 571, a sliding shaft 573 fixedly connected to the connecting block 571, and a pair of sliding plates 572. The pair of sliding plates 572 are symmetrically arranged on both sides of the sliding shaft 573. The sliding plates 572 and the sliding shaft 573 slide through the hollow structure. The elastic element is a spring 574. The spring 574 is sleeved on the sliding shaft 573 and abuts against the connecting block 571 and the hollow structure. The spring 574 and the sealing plate 59 are located on both sides of the hollow structure.

[0087] Specifically, the reciprocating moving mechanism two includes a sliding member two and an elastic element two. The sliding member two is slidably connected to the exhaust structure one 9, and the sealing plate two 566 is fixedly connected to the sliding member two. The two ends of the elastic element two in the elastic deformation direction are respectively connected to the sliding member two and the exhaust structure one 9. When an external force is applied to the sliding member two, the sliding member two slides relative to the exhaust structure one 9, causing the sealing plate two 566 to move away from the exhaust structure one 9, and causing the elastic element two to undergo elastic deformation. After the external force disappears, the elastic element two that has undergone elastic deformation causes the sliding member two to slide in the opposite direction relative to the exhaust structure one 9, and then causes the sealing plate two 566 to approach and block the exhaust structure one 9.

[0088] Specifically, the second sliding element includes a connecting rod 561 and a sliding cylinder 563 fixedly connected to one end of the connecting rod 561. The sliding cylinder 563 slides through the exhaust structure 9 and is fixedly connected to the second sealing plate 566. The second elastic element is a second spring 565, which is sleeved on the sliding cylinder 563 and abuts against the end of the sliding cylinder 563 away from the second sealing plate 566. The second spring 565 and the second sealing plate 566 are located on both sides of the exhaust structure 9. The other end of the connecting rod 561 extends out of the outer shell.

[0089] Example 3: This embodiment proposes an inflatable recliner, such as Figure 14 and Figure 15 As shown, it includes an interconnected support body 2 and an airbag 1. The support body 2 is used to support the weight of a human body, and preferably, the support body 2 is made of Oxford cloth. The airbag 1 is constructed to surround the lower surface edge of the support body 2, thereby defining a cavity 3 on the lower surface of the support body 2. When a person lies on the support body 2, the person sinks into the cavity 3 along with the support body 2. Compared with conventional inflatable recliners where the cavity 3 is filled with airbag 1, the inflatable recliner of this embodiment is softer and more comfortable.

[0090] In this embodiment, as Figure 14 and Figure 15As shown, the airbag 1 is equipped with an inflation device 5 as described in Embodiment 1 or Embodiment 2. The inflation device 5 inflates the airbag 1 and deflates the air inside the airbag 1. Specifically, the control drive 54 drives the fan 55 to rotate and draw in outside air into the outer shell. Then, the air passes through the first air outlet structure 8 or sequentially through the first air outlet structure 8 and the second air outlet structure, and pushes open the sealing sheet 59 to enter the airbag 1, thus inflating the airbag 1. When the fan 55 stops rotating, the reciprocating movement mechanism 1 drives the sealing sheet 59 to reset and seal the first air outlet structure 8 or the second air outlet structure to prevent air leakage. When airbag 1 needs to be deflated, pressing the deflation button 562 moves the sealing plate 566 away from the exhaust structure 9 or the exhaust structure 2. At this time, the high-pressure gas in airbag 1 passes through the exhaust structure 9 or the exhaust structure 2 and the exhaust structure 9 in sequence before entering the outer shell. Finally, it flows out of the outer shell from the air inlet structure. Releasing the press of the deflation button 562 causes the reciprocating moving mechanism 2 to move the sealing plate 566 back to its original position and seal the exhaust structure 9 or the exhaust structure 2, preventing air leakage. Therefore, by controlling the time of pressing the deflation button 562, the deflation amount of airbag 1 can be controlled, achieving controllable deflation. The deflation amount of airbag 1 can be freely adjusted according to the usage needs of the inflatable recliner, effectively meeting the usage needs of inflatable products.

[0091] Furthermore, such as Figure 14 and Figure 15 As shown, the airbag 1 has a pressure-bearing part 11 and an adjusting part 12. The adjusting part 12 is inclined relative to the pressure-bearing part 11. Changes in the air pressure inside the airbag 1 cause changes in the tilt angle of the adjusting part 12 under its own weight. Specifically, a decrease in the air pressure inside the airbag 1 causes a decrease in the tilt angle of the adjusting part 12 relative to the horizontal plane, and vice versa. The carrier 2 has a seat part 21 and a backrest part 22. The seat part 21 is connected to the pressure-bearing part 11, and the backrest part 22 is connected to the adjusting part 12. The seat part 21 is used for the lower body to sit on, and the backrest part 22 is used for the upper body to lean on. This design allows the tilt angle of the backrest part 22 of the inflatable recliner to be adjusted, improving the comfort of the inflatable recliner and enriching its functions.

[0092] In this embodiment, further, such as Figure 14 and Figure 15 As shown, the airbag 1 is provided with an air release hole 7, and a sealing plug 6 is inserted into the air release hole 7. Removing the sealing plug 6 allows the high-pressure gas inside the airbag 1 to be released quickly through the air release hole 7, which is suitable for use when the inflatable recliner is folded up.
