Description

Technical Field

[0001] This invention relates to the field of inflatable product technology, and more specifically, to a dual-function air pump and inflatable product based on a sliding switching air path. Background Technology

[0002] Portable air pumps are widely used for inflating and deflating air cushions, air bags, swimming rings, and air tanks. Most existing air pumps only have a single inflation or deflation function, requiring users to prepare two different types of pumps when simultaneous inflation and deflation are needed. To improve ease of use, some products have introduced air path switching structures, such as knob-type or interface-type switches. Knob-type switches change the air path direction by rotating an external knob, which drives an internal reversing valve or guide mechanism to switch between inflation and deflation. However, rotating the knob requires overcoming internal springs and friction, resulting in significant resistance and a less smooth operation. Furthermore, the complex internal structure and high manufacturing cost, coupled with the tendency for the reversing valve's sealing performance to deteriorate over time, make interface-type switches inconvenient. Frequent disassembly and assembly can cause wear and leakage at the interface. Summary of the Invention

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] In the description of this invention, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed, they are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0022] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0023] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0024] Please refer to Figures 1-9 This embodiment provides a dual-function air pump based on a sliding switching air path, which includes a housing 100, a first valve 200, a second valve 300, and a core assembly 400. The housing 100 is provided with a mounting cavity 101 and a first inlet / outlet 102 and a second inlet / outlet 103, both of which are connected to the mounting cavity 101; the first valve 200 and the second valve 300 are both mounted on the housing 100, and both are used to open or close the mounting cavity 101; the core assembly 400 is located inside the mounting cavity 101 and is slidably connected to the housing 100, and the core assembly 400 is used to make the airflow flow in a set direction. When the movement assembly 400 slides relative to the outer casing 100, it has a first position and a second position that can be switched between each other. When it is in the first position, the movement assembly 400 opens the first valve 200 and closes the first inlet and outlet 102 at the same time, so that the first valve 200 can be connected to the second inlet and outlet 103 through the mounting cavity 101. When it is in the second position, the movement assembly 400 opens the second valve 300 and closes the second inlet and outlet 103 at the same time, so that the second valve 300 can be connected to the first inlet and outlet 102 through the mounting cavity 101.

[0025] As described above, the working principle of the dual-function air pump based on the sliding switching air path provided in this embodiment is as follows: The dual-function air pump is used in conjunction with the inflation product. After assembly, both the first valve 200 and the second valve 300 are located inside the inflation chamber of the inflation product, while the first inlet / outlet 102 and the second inlet / outlet 103 are exposed to the external environment. In the initial state, the core assembly 400 is in the intermediate position between the first and second positions. At this time, both the first valve 200 and the second valve 300 are closed. Even if the core assembly 400 is activated, causing the gas to flow in the set direction, it only accelerates the flow of external air between the first inlet / outlet 102 and the second inlet / outlet 103, and cannot achieve inflation or deflation of the inflation product, thus not affecting the internal air pressure of the inflation product. When inflating the product, the mechanism assembly 400 slides relative to the outer shell 100 to the first position. At this time, the first valve 200 and the second inlet / outlet 103 are open, while the second valve 300 and the first inlet / outlet 102 are closed. After the mechanism assembly 400 is activated, the airflow also flows in the set direction. External gas enters the mounting cavity 101 through the second inlet / outlet 103, passes through the mechanism assembly 400, and then enters the inflation chamber through the first valve 200, thus achieving inflation. Similarly, when deflating the product, the mechanism assembly 400 slides relative to the outer shell 100 and switches from the first position to the second position. At this time, the second valve 300 and the first inlet / outlet 102 are open, while the first valve 200 and the second inlet / outlet 103 are closed. After the mechanism assembly 400 is activated, the airflow also flows in the set direction. Gas in the inflation chamber enters the mounting cavity 101 through the second valve 300, passes through the mechanism assembly 400, and then exits through the first inlet / outlet 102, thus achieving inflation. In this way, there is no need to repeatedly disassemble and reassemble the interface, the inflation and deflation operation is convenient, there is no need to overcome the spring force, and the operation is smooth.

[0026] It should be understood that once the core component 400 is started, regardless of its location, the airflow direction of the core component 400 remains unchanged, and its operating logic is simple and reliable.

[0027] It is worth noting that the dual-function air pump can be used in a variety of inflatable products, such as, but not limited to, air cushions, air bags, swimming rings, and air tanks.

[0028] In addition, a dual-function air pump refers to an air pump that can deflate or inflate inflatable products by adjusting the position of the core component 400, making it easy to operate.

[0029] The following embodiments illustrate the details of the dual-function air pump of this application by way of example.

[0030] Please refer to Figures 1-9 In this embodiment, optionally, the dual-function air pump includes a housing 100, a first valve 200, a second valve 300, and a core assembly 400. The first valve 200, the second valve 300, and the core assembly 400 all cooperate with the housing 100.

[0031] The outer casing 100 includes a main casing 110, a first rotating cover 120 and a second rotating cover 130. The first rotating cover 120 and the second rotating cover 130 are rotatably connected to the main casing 110. The movement assembly 400 is installed inside the main casing 110 and slides with the main casing 110.

[0032] Please refer to Figures 1-7 Specifically, the main housing 110 includes a bottom housing 111, a top cover 112, a first limiting plate 113, a second limiting plate 114, and a resilient latching assembly 115. The bottom housing 111 is generally rectangular and has a rectangular groove. One side of the top cover 112 is rotatably connected to the bottom housing 111, and the other side is detachably connected to the bottom housing 111 via the resilient latching assembly 115. When the top cover 112 is connected to the bottom housing 111, the top cover 112 closes the opening of the rectangular groove, and the two cooperate to define the mounting cavity 101. When the top cover 112 rotates to open the opening, the movement assembly 400 can be exposed, facilitating disassembly and maintenance. By pressing the resilient latching assembly 115, the locking of the top cover 112 and the bottom housing 111 can be released, allowing the top cover 112 to rotate and open, making the operation convenient and quick.

[0033] Please refer to Figure 3 Optionally, the bottom shell 111 has a first sidewall 1111 and a second sidewall 1112 arranged at relative intervals along its length. A first valve port 1113 is provided on the first sidewall 1111, and a second valve port 1114 is provided on the second sidewall 1112. The first valve port 1113 and the second valve port 1114 correspond to the first valve 200 and the second valve 300, respectively. The first valve 200 can open or close the first valve port 1113, and the second valve 300 can open or close the second valve port 1114.

[0034] Please refer to Figure 1 , Figure 2 and Figure 5Optionally, the top cover 112 is generally a rectangular plate. The first inlet / outlet 102 and the second inlet / outlet 103 are both disposed on the top cover 112 and spaced apart along its length. When the top cover 112 is connected to the bottom shell 111, the first inlet / outlet 102 is closer to the first side wall 1111, and the second inlet / outlet 103 is closer to the second side wall 1112. A first limiting plate 113 is installed inside the first inlet / outlet 102, and a second limiting plate 114 is installed inside the second inlet / outlet 103. A first rotating cover 120 is rotatably installed inside the first inlet / outlet 102, and a second rotating cover 130 is rotatably installed inside the second inlet / outlet 103. In the initial state, that is, when the movement assembly 400 is in the intermediate position between the first position and the second position, the first rotating cover 120 and the second rotating cover 130 are basically parallel to the top cover 112. The inner side of the first rotating cover 120 is attached to the first limiting plate 113, which limits the depth of the first rotating cover 120 when it rotates into the first inlet / outlet 102. Similarly, the inner side of the second rotating cover 130 is attached to the second limiting plate 114, which limits the depth of the second rotating cover 130 when it rotates into the second inlet / outlet 103. At the same time, the edge of the first limiting plate 113 is retracted into the edge of the first rotating cover 120, and the first rotating cover 120 is not completely blocked by the first limiting plate 113, which makes it easy to fasten the first rotating cover 120 from the edge and to rotate and open the first rotating cover 120. Similarly, the edge of the second limiting plate 114 retracts into the edge of the second rotating cover 130, and the second rotating cover 130 is not completely covered by the second limiting plate 114, so that the second rotating cover 130 can be fastened from the edge of the second rotating cover 130, and the second rotating cover 130 can be rotated to open.

[0035] Furthermore, a lock hole 1121 is provided on the side where the top cover 112 and the bottom shell 111 are detachably connected.

[0036] Please refer to Figure 2 , Figure 6 and Figure 7Optionally, the elastic snap-fit ​​assembly 115 includes a pressing member 1151, a locking block 1152, an elastic body 1153, and a housing 1156. The housing 1156 is mounted on the top of the bottom shell 111, and the pressing member 1151 is slidably connected to the housing 1156 along the depth direction of the groove in the bottom shell 111. The pressing member 1151 is provided with a driving inclined surface 1154. The locking block 1152 is slidably connected to the bottom shell 111 along the length direction of the bottom shell 111, and the locking block 1152 is provided with a driving hole 1155, in which the pressing member 1151 passes. One end of the elastic body 1153 is connected to the bottom shell 111, and the other end is connected to the locking block 1152. The elastic body 1153 has a tendency to insert the locking block 1152 into the locking hole 1121 on the top cover 112. Under normal circumstances, under the action of the elastic body 1153, the locking block 1152 is inserted into the locking hole 1121 of the top cover 112, and the top cover 112 cannot be opened automatically. When force is applied to the pressing member 1151, it moves downward, and the driving surface presses the locking block 1152, overcoming the elastic force of the elastic body 1153, so that the locking block 1152 moves away from the top cover 112, and the locking block 1152 is pulled out. At this time, the top cover 112 can be opened, which is convenient to operate.

[0037] It should be understood that the elastomer 1153 can be a spring.

[0038] Please refer to Figure 2 and Figure 6 In this embodiment, optionally, the core assembly 400 includes a core housing 410, a fan assembly 420, an anti-rotation protrusion 430, and control switches (not shown). The core housing 410 is located within and slidably connected to the bottom housing 111, with the sliding direction being the length direction of the bottom housing 111. The fan assembly 420 is installed inside the core housing 410, the anti-rotation protrusion 430 is connected to the core housing 410, and there can be two control switches, both installed on the core housing 410. Both control switches are electrically connected to the fan assembly 420, and the two control switches can independently control the fan assembly 420 to turn on or off.

[0039] Optionally, the core housing 410 includes a middle housing 411, an upper cover 412, and a lower cover 413. The upper cover 412 and the lower cover 413 are respectively installed at both ends of the middle housing 411 and are detachably connected to the middle housing 411. A fan assembly 420 can be installed inside the core housing 410, and both the upper cover 412 and the lower cover 413 are provided with ventilation holes. The fan assembly 420 is an axial flow fan. After the fan assembly 420 is started, it can make the gas flow in a set direction, causing the gas to flow from the upper cover 412 side to the lower cover 413 side. For ease of description, the direction from the upper cover 412 to the lower cover 413 side can be called the first direction; conversely, the direction from the lower cover 413 to the upper cover 412 side can be called the second direction. The first and second directions are opposite, and both the first and second directions are along the axial direction of the fan assembly 420 and are also consistent with the length direction of the bottom housing 111. Please refer to... Figure 6 The first direction is the direction indicated by arrow ab, and the second direction is the direction indicated by arrow ba.

[0040] Furthermore, the top of the middle shell 411 is provided with a drive groove 414, which has a first drive groove wall 4141 and a second drive groove wall 4142 arranged at intervals in a first direction or a second direction. A first rotating cover 120 is used to contact the first drive groove wall 4141 to drive the movement shell 410 to slide along the first direction. A second rotating cover 130 is used to contact the second drive groove wall 4142 to drive the movement shell 410 to slide along the second direction. Figure 6 Taking the medium-angle view as an example, the first rotating cover 120 rotates clockwise and contacts the first drive groove wall 4141, causing the movement assembly 400 to rotate along the first direction. When the first rotating cover 120 is approximately in a vertical state, that is, rotated 90°, the movement assembly 400 switches to the first position. Similarly, the second rotating cover 130 rotates counterclockwise and contacts the second drive groove wall 4142, causing the movement assembly 400 to rotate along the second direction. When the second rotating cover 130 is approximately in a vertical state, that is, rotated 90°, the movement assembly 400 switches to the second position.

[0041] Please combine Figure 8 and Figure 9Optionally, the blower assembly 420 includes a motor body 421, a motor bracket 422, a fan blade 423, a middle bracket 424, a circuit board 425, and a battery 426. The motor body 421 can be fixed to one side of the motor bracket 422 with screws. The rotation shaft of the motor body 421 extends along the sliding direction of the core assembly 400, i.e., the first direction or the second line of defense, and passes through the motor bracket 422. The fan blade 423 is press-fitted onto the rotation shaft of the motor body 421 and is located on the other side of the motor bracket 422. After the motor body 421 is started, it can drive the fan blade 423 to rotate, thereby providing power for inflation and deflation. One end of the motor bracket 422 is connected to the middle bracket 424, which is inserted and fixed in the middle shell 411, serving as a support and positioning function; the other end of the motor bracket 422 can be ultrasonically welded to the upper cover 412. The upper cover 412 is set as a hollow part, which can serve as a cover for the fan blade 423, serving to protect the fan blade 423. Circuit board 425 is mounted on the middle bracket 424 and is electrically connected to the motor body 421. There can be multiple batteries 426, all of which are mounted on the middle bracket 424 and arranged at intervals around the circumference of the middle bracket 424. The multiple batteries 426 are connected in series and are all electrically connected to the circuit board 425. The batteries 426 can provide power to the motor body 421.

[0042] Obviously, in some embodiments, the motor body 421 can also be connected to other power sources. Alternatively, the battery 426 can be configured as a rechargeable battery that can be reused multiple times at a low cost.

[0043] Optionally, the anti-rotation protrusion 430 is disposed on the bottom wall of the drive groove 414, and located between the first drive groove wall 4141 and the second drive groove wall 4142, approximately at the midpoint between the first drive groove wall 4141 and the second drive groove wall 4142. The anti-rotation protrusion 430 has a gap from both the first drive groove wall 4141 and the second drive groove wall 4142. When the first rotating cover 120 rotates clockwise, causing the movement housing 410 to slide along the first direction, it can engage between the first drive groove wall 4141 and the anti-rotation protrusion 430. Similarly, when the second rotating cover 130 rotates counterclockwise, causing the movement housing 410 to slide along the second direction, it can engage between the second drive groove wall 4142 and the anti-rotation protrusion 430. By providing the anti-rotation protrusion 430, when the first rotating cover 120 drives the movement assembly 400 to move to the first position, the rotation of the first rotating cover 120 can be restricted, thereby keeping the movement assembly 400 in the first position, resulting in a stable and reliable structure. Similarly, when the second rotating cover 130 moves the movement to the second position, the second rotating cover 130 is not easy to rotate clockwise under the limit of the anti-rotation protrusion 430, which can keep the movement assembly 400 in the second position.

[0044] It should be understood that when the movement assembly 400 is in the first position, to reset the movement assembly 400, the first rotating cover 120 can be manually rotated counterclockwise to release its restriction on the movement assembly 400. Simultaneously, the movement assembly 400 can be manually pushed to slide back to its original position in the second direction. During manual reset, tools or the user's hand can be used to insert into and contact the movement housing 410 through the first inlet / outlet 102 or the second inlet / outlet 103, causing the movement housing 410 to slide back to its original position. Similarly, when the movement assembly 400 is in the second position, the movement housing 410 can be slid back to its original position in the first direction. To prevent slippage during reset, a slot can be provided on the top of the movement housing 410, allowing tools or the user's hand to engage with the slot, saving time and effort.

[0045] It should be noted that the control switch can be installed on the housing 410, serving as a physical switch. When the housing 410 moves to the first position, one of the control switches is activated, turning on the fan assembly 420. When the housing 410 moves to the second position, the other control switch is activated, turning on the fan assembly 420. The fan assembly 420 is conveniently and reliably turned on. Obviously, in other embodiments, only one control switch can be provided, which can be activated when the housing 410 is in either the first or second position, thereby automatically turning on the fan assembly 420. Furthermore, after the housing 410 moves away from the first or second position, the fan assembly 420 stops working.

[0046] Obviously, in some embodiments, the fan assembly 420 can also be started and stopped independently via a remote control or control panel.

[0047] In this embodiment, optionally, both the first valve 200 and the second valve 300 can be configured as one-way valves, and their structures and working principles can be configured to be the same.

[0048] Please refer to Figures 1-2 Specifically, the first valve 200 includes a first protective cover 210, a first elastic element 220, and a first valve plate 230. The first protective cover 210 is fixed to the outside of the first side wall 1111 of the bottom shell 111. The first protective cover 210 is a mesh cover that allows gas flow. The first valve plate 230 is slidably mounted on the first side wall 1111 of the bottom shell 111 and within the area enclosed by the first protective cover 210. The shaft of the first valve plate 230 can extend into the mounting cavity 101, while the remaining part is located outside the first side wall 1111. The first elastic element 220 is connected to both the first protective cover 210 and the first valve plate 230, and is used to give the first valve plate 230 a tendency to close the first valve port 1113. That is, in the initial state, under the action of the first elastic element 220, the first valve plate 230 is only attached to the outside of the first side wall 1111 and the first valve port 1113 is closed. The shaft of the first valve plate 230 extends into the mounting cavity 101. At this time, the first valve 200 is in the normally closed state.

[0049] Meanwhile, the second valve 300 includes a second protective cover 310, a second elastic element 320, and a second valve plate 330. The second protective cover 310 is fixed to the outside of the second side wall 1112 of the bottom shell 111, and is a mesh cover that allows gas flow. The second valve plate 330 is slidably mounted on the second side wall 1112 of the bottom shell 111 and within the area enclosed by the second protective cover 310. The shaft of the second valve plate 330 can extend into the mounting cavity 101, while the remaining part is located outside the second side wall 1112. The second elastic element 320 is connected to both the second protective cover 310 and the second valve plate 330, and is used to give the second valve plate 330 a tendency to close the second valve port 1114. That is, in the initial state, under the action of the second elastic element 320, the second valve plate 330 is only attached to the outside of the second side wall 1112 and the second valve port 1114 is closed. The shaft of the second valve plate 330 extends into the mounting cavity 101. At this time, the second valve 300 is in the normally closed state.

[0050] It should be understood that both the first elastic element 220 and the second elastic element 320 can be configured as springs.

[0051] When the movement assembly 400 slides along the first direction, the lower cover 413 can contact the shaft of the first valve plate 230 and overcome the elastic force of the first elastic member 220 to open the first valve plate 230, thus opening the first valve port 1113. Similarly, when the movement assembly 400 slides along the second direction, the upper cover 412 can contact the shaft of the second valve plate 330 and overcome the elastic force of the second elastic member 320 to open the second valve plate 330, thus opening the second valve port 1114.

[0052] The working principle of the dual-function air pump provided in this embodiment is as follows: Please refer to Figure 6 The dual-function air pump is sealed to the inflatable product. The first valve 200 and the second valve 300 are both located inside the inflation chamber of the inflatable product, while the first inlet / outlet 102 and the second inlet / outlet 103 are exposed to the external environment. In the initial state, the core assembly 400 is in the middle position, the first valve 200 and the second valve 300 are both closed, and the blower assembly 420 is in a stopped state.

[0053] When inflation is required, the first rotating cover 120 is rotated clockwise. The right side of the first rotating cover 120 enters the drive groove 414 and contacts the wall 4141 of the first drive groove, pushing the core assembly 400 to slide along the first direction. When it slides to the first position, the first valve plate 230 is pushed open, the first valve port 1113 is opened, and the first inlet / outlet 102 is closed by the core housing 410, while the second inlet / outlet 103 is opened. At the same time, the control switch is activated, and the blower assembly 420 is turned on. The blower assembly 420 blows air in the set direction, i.e., the first direction. The gas enters from the second inlet / outlet 103, passes through the mounting cavity 101 and the core assembly 400, and is discharged from the first valve port 1113, thus entering the inflatable product to achieve inflation. After inflation is completed, the core assembly 400 can be manually slid back to the right, and the first rotating cover 120 can be rotated back to its original position counterclockwise. During this process, the second valve 300 is closed, and because the airflow flows inside the second valve 300 in a direction away from the second valve 300, a phenomenon of low pressure inside and high pressure outside is formed. The second valve 300 can better close the second valve port 1114, making it less prone to air leakage and with high inflation efficiency.

[0054] When venting is required, the second rotating cover 130 is rotated clockwise. The right side of the second rotating cover 130 enters the drive groove 414 and contacts the wall 4142 of the second drive groove, pushing the core assembly 400 to slide in the second direction. When it slides to the second position, the second valve plate 330 is pushed open, the second valve port 1114 opens, and the second inlet / outlet 103 is closed by the core housing 410, while the first inlet / outlet 102 opens. At the same time, the control switch is activated, and the fan assembly 420 is turned on. The fan assembly 420 blows air in the set direction, i.e., the first direction. The gas in the inflation chamber enters the mounting chamber 101 from the second valve port 1114, flows through the core assembly 400, and is discharged from the first inlet / outlet 102, thus achieving venting. During this process, the first valve 200 is closed, and because the airflow flows from inside the first valve 200 away from it, a phenomenon of low pressure on the inside and high pressure on the outside is formed. The first valve 200 can better close the first valve port 1113, making it less prone to leakage and achieving high venting efficiency.

[0055] The dual-function air pump based on the sliding switching air path provided in this embodiment can switch between inflation and deflation functions through the sliding core assembly 400, making operation convenient and flexible.

[0056] This embodiment also provides an inflatable product, which includes an inflatable component and a dual-function air pump as described in the above embodiment. The housing 100 of the dual-function air pump is sealed to the inflatable component.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
