INFLATABLE MATTRESS, AN AIR PUMP WITH A PRESSURE DETECTION STRUCTURE, AN AIR PUMP WITH A FINE-TUNING STRUCTURE, AND A RAPID INFLATING AND DEFLATING AIR PUMPRelated Applications

[0001] This application is related to Chinese Application No. CN202323222921.6, filed November 27, 2023, CN202323214238.8, filed November 27, 2023, CN202323356153.3, filed December 8, 2023, and CN202323352368.8, filed December 8, 2023, the entire disclosures of which are expressly incorporated herein by reference.Field of the Disclosure

[0002] The present disclosure relates to an inflatable product, such as an air mattress, and air pumps for said inflatable products. The air pumps may include an air pressure detection structure, a fine-tuning structure, or both the pressure detection structure and the fine-tuning structure. The air pump may be configured to rapidly inflate and deflate an inflatable product and further configured to perform fine-tuning inflation or deflation of the inflatable product.Background of the Disclosure

[0003] Air mattresses have strong flexibility and elasticity, adjustable firmness, and provide good comfort to the user. Therefore, air mattresses are increasingly popular among consumers. To adjust the firmness of the air mattress, existing air mattresses are generally integrated with an air pump. For example, the air pump may be embedded in the wall of the inflatable bladder, such as by welding the air pump to a wall of the inflatable bladder. However, the weight of the air pump is relatively large, and the air pump will pull down the connection joint of the inflatable bladder wall, causing the joint between the air pump and the inflatable bladder wall to deform. The weight of the air pump may even damage the inflatable bladder wall. Additionally, because the air pump is embedded in the inflatable bladder, to ensure the air tightness of the inflatable bladder, the connection between the air pump and the inflatable bladder needs to be handled carefully. If the air pump is damaged, it will be very troublesome to replace. After replacing the air pump, it is difficult to ensure the air tightness of the inflatable bladder. Additionally, replacing the air pump often needs to be performed by professionals, increasing the after-sales cost of the inflatable product.

[0004] Air pumps may be used to inflate and / or deflate inflatable products. At present, during inflation, the user determines whether the inflatable product is fully inflated by visually inspecting the inflatable product or through tactile feedback, such as by pressing down on the inflatable product. The specific inflation pressure value cannot be intuitively understood. To accurately control the inflation pressure of inflatable products, some air pumps are currently equipped with pressure detectors that include a pressure detection tube in fluid communication with the inflatable product. To ensure the accuracy of pressure detection, the pressure detection tube of current air pumps with pressure detectors is kept away from the inflation tube to prevent the air flow of the inflation tube from affecting the air pressure in the pressure detection tube. For example, for an air pump installed on an inflatable product, the inflation pipe is installed at the installation location of the air pump. One end of the pressure detection pipe is connected to the circuit board inside the air pump, and the other end is fixed at a location away from the installation of the air pump. This makes the installation and use of the air pump more cumbersome.

[0005] Air pumps for inflatable products may include a channel switching structure for switching the air pump between an inflation or deflation configuration and a closed configuration. During inflation or deflation of the inflatable product, the channel switching structure may generally work as follows: The air pump motor starts to inflate or deflate the inflatable product, the channel switching structure moves, such as by translating or rotating, and an air channel is opened between the inflatable product and atmosphere via the pump. When the internal air pressure of the inflatable product reaches the specified positive or negative pressure, the switching structure operates to close the air channel. The air pump motor stops inflating or deflating.

[0006] When the internal air pressure of the inflatable product reaches the specified pressure and the channel switching structure rotates to the channel closing position, the channel is gradually closed. At this time, the air pump motor is still working and the air flow it generates is relatively large. This leads to the following problem: After the internal air pressure of the inflatable product reaches the specified pressure, the inflatable product will continue to be inflated or deflated, causing the internal pressure of the inflatable product to be greater or less than the expected pressure value. Thus, when the current air pump with achannel switching structure is used, it cannot accurately control the pressure value within the inflatable product.

[0007] For inflatable products with a large volume, an air pump with a large pumping volume is generally used so that inflation or deflation can be completed quickly. However, an air pump with a large pumping volume can only achieve rapid inflation or deflation and cannot accurately determine the pressure inside the air bladder. For inflatable products with large volumes that need to be filled quickly and accurately achieve the preset air pressure, current air pumps cannot meet their use needs.

[0008] Improvements on the foregoing are desired.Summary of the Disclosure

[0011] The present disclosure provides an inflation and deflation interface on the air bladder and connects the inflation and deflation interface through an air pump placed outside the air bladder to control the inflation and deflation of the air bladder, thereby adjusting the softness and hardness of the air mattress. Additionally, the air pump may be installed through the support bar, and the support bar may be against the side wall of the air bladder, which may ensure that the air pump is reliably supported, has good installation stability, and does not easily interfere with the use of the air bladder. By placing the air pump outside the air bladder, the present disclosure makes the connection between the air pump and the air bladder more convenient, and the operation is simple and can be completed without the need for professionals, which is beneficial to maintenance and after-sales service.

[0012] The present disclosure provides a pressure detection structure for an air pump, which may not only ensure the accuracy of pressure detection but may also simplify the pressure detection structure of the air pump, making the installation and use of the air pump more convenient.

[0013] In embodiments, the present disclosure provides a pressure detection structure of an air pump, which may include an inflation and deflation joint, a pressure detection element, and a pressure detection tube. The inflation and deflation joint may form an inflation and deflation flow channel and a pressure detection flow channel. At least part of the pressure detection flow channel may be parallel with the inflation and deflation flow channel. One end of the pressure detection tube may be connected to the pressure detection element, and the other end may be connected to the pressure detection flow channel.

[0014] In another embodiment of the present disclosure, the inflation and deflation joint may be provided with a detection interface connected to the pressure detection flow channel, and the detection interface may be connected to the pressure detection pipe.

[0015] In yet another embodiment of the present disclosure, the part of the pressure detection flow channel that is parallel to the inflation and deflation flow channels may be close to one end of the inflation and deflation connector that matches the inflatable product.

One end of the inflation and deflation flow channel may be connected to the inflation and deflation ports inside the air pump, and the other end may be connected to the inside of the inflatable product during inflation.

[0017] In another embodiment of the present disclosure, the air pump may include a body, a panel assembly fitted on the body, a circuit board installed inside the body, and an inflation and deflation assembly installed inside the body. The pressure detection element may be installed on the circuit board, and the pressure detection tube may be installed on the circuit board. Within the body, the inflation and deflation assembly may include at least an air pump set.

[0018] In another embodiment of the present disclosure, the inflation and deflation connector may be fixed at the bottom of the body, and one end of the inflation and deflationconnector may be located inside the body and cooperate with the air pump set. The other end may pass through the bottom of the body and extend outside the body.

[0019] In another embodiment of the present disclosure, the inflation and deflation joint and the main body may be an integrated structure.

[0020] In another embodiment of the present disclosure, the inflation and deflation assembly may include an airway switching group. The airway switching group may be arranged between the air pump assembly and the inflation and deflation joints and may be used to connect or disconnect the inflation and deflation joints from the air pump assembly.

[0021] In another embodiment of the present disclosure, when the number of the inflation and deflation connectors is more than two, the airway switching group may also be used to connect or disconnect one or more inflation and deflation connectors from the air pump set.

[0022] In another embodiment of the present disclosure, the inflation and deflation connector may be equipped with a quick connector, and the quick connector may be connected to the valve on the inflatable product through the inflation and deflation pipe.

[0023] Exemplary advantages of one or more embodiments of the present disclosure may include not only ensuring the accuracy of pressure detection, but also simplifying the pressure detection structure of the air pump, making the installation and use of the air pump more convenient. The present disclosure provides a pressure detection flow channel in the inflation and deflation joint, so that the pressure detection pipe may not need to extend out of the air pump, thus simplifying the pressure detection structure of the air pump and making the installation and use of the air pump more convenient. Because the pressure detection flow channel is at least partially parallel to the inflation and deflation flow channel air entering the inflatable product during the initial stages of inflation will form a negative pressure at the pressure detection flow channel port and will not inject pressure into the pressure detection flow channel. When the air pressure in the inflatable product gradually increases, the end of the inflation and deflation connector matching the inflatable product will be subject to back pressure. At this time, air pressure will be generated in the pressure detection flow channel, and the pressure detection element detects to the air pressure inside the inflatable product. Therefore, embodiments of the present disclosure may ensure that the pressure detection element accurately detects the pressure in the inflatable product.

[0024] The present disclosure provides a fine-tuning structure of an air pump, which may realize fine-tuning of the internal pressure of the inflatable product, thereby more accurately controlling the internal pressure of the inflatable product.

The turntable may be provided with air inflation and deflation holes and small holes, and the outer circumference of the turntable may be provided with at least three trigger strips that cooperate with the trigger switch. The valve seat may be tightly fitted under the turntable, and the valve seat may include at least one air inflation and deflation channel. One end of the air inflation and deflation channel may face the turntable, and the other end may extend outside the body;

[0026] In another embodiment of the present disclosure, the three trigger strips may include a first trigger strip, a second trigger strip, and a third trigger strip. As the driving member drives the turntable to rotate, when the touch switch detects the first trigger strip, the inflation and deflation holes on the turntable are connected to the pump chamber and the inflation and deflation channel. When the trigger switch detects the second trigger bar, the small hole on the turntable may connect the pump chamber and the air inflation and deflation channel. When the trigger switch detects the third trigger bar, the turntable cuts off the connection between the pump chamber and the inflation and deflation channel.

[0027] In another embodiment of the present disclosure, the switching assembly may also include an upper pump cover, which may be fitted between the air pump assembly and the turntable. The driving assembly may be installed on the upper pump cover.

There may be a gap between the internal pressure of the inflatable product and the preset pressure. At this time, the turntable may be driven to rotate through the driving mechanism. When the trigger switch detects the second trigger bar, it stops rotating, allowing the small hole on the turntable to connect the inflation and deflation channels with the pump chamber. Then, the air pump may inflate or deflate through the small holes, thereby achieving fine adjustment of the internal pressure of the inflatable product. Thus, the air pump can accurately control the internal pressure of the inflatable product.

[0051] When the turntable of the air valve group communicates with the pump chamber of the quick-inflation pump set and the inflation-deflation channel through the inflating and deflating holes, the quick-inflating pump set may be started to quickly inflate and deflate the inflatable product. When the turntable separates the pump chamber of the quick-inflation pump unit from the charging and deflating channels, the vacuum air pump unit starts, the solenoid valve opens, and air enters the body from the outside, passes through the vacuum air pump unit and the solenoid valve unit in sequence, enters the charging chamber through the fine-tuning hole, and finally enters the inflatable product, thereby achieving fine-tuning inflation of the inflatable product so that the internal pressure of the inflatable product can be accurately controlled. Alternatively, air in the inflatable product enters the inflation and deflation channel, and then sequentially enters the solenoid valve group through the fine- tuning hole before entering the vacuum air pump group and finally discharging from the body to fine tune the air pressure of the inflatable product so that the internal pressure of the inflatable product can be accurately controlled.

Although the drawings represent embodiments of various features and components according to the present disclosure, the drawings are not necessarily to scale and certain features may be exaggerated in order to better illustrate and explain the present disclosure.Detailed Description of the Embodiments

[0149] For the purposes of promoting an understanding of the principals of the disclosure, reference will now be made to the embodiments illustrated in the drawings, which are described below. The embodiments disclosed below are not intended to be exhaustive or limit the disclosure to the precise form disclosed in the following detailed description.Rather, the embodiments are chosen and described so that others skilled in the art may utilize their teachings. It will be understood that no limitation of the scope of the disclosure isthereby intended. The disclosure includes any alterations and further modifications in the illustrative devices and described methods and further applications of the principles of the disclosure which would normally occur to one skilled in the art to which the disclosure relates.

[0150] In the description of the present disclosure, it should be noted that the terms "up", "down", "inside", "outside", "top / bottom", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the attached drawings, only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present disclosure. In addition, the terms "first" and "second" are only used to describe and cannot be understood as indicating or implying relative importance.

[0151] In the description of the present disclosure, it should be noted that unless otherwise specified and limited, the terms "installation", "set with", "set / connected", "connected", etc. should be understood broadly. For example, "connected" can be a wall mounted connection, a detachable connection, or an integrated connection, can be a mechanical connection, can be an electrical connection, can be directly connected, or can be indirectly connected through an intermediate medium, can be the internal connection between two components, and for ordinary technical personnel in this field, the specific meaning of the above terms in the present disclosure can be understood in a specific situation.

[0152] The terms “couples”, “coupled”, “coupler”, and variations thereof are used to include both arrangements wherein two or more components are in direct physical contact and arrangements wherein the two or more components are not in direct contact with each other (e.g., the components are “coupled” via at least a third component, but yet still cooperates or interact with each other).

[0153] Referring to FIGS. 1-3, the present disclosure provides an inflatable mattress, which may include a bed cover 8, a first support bar 40, an air pump 100, and two inflatable bladders 20. While the illustrated embodiment depicts two inflatable bladders 20, the inflatable mattress may include fewer than two or more than two inflatable bladders 20. Thebed cover 8 may be a quilted top component. In the illustrated embodiment, the bed cover 8 may include an upper bed cover 11 and a lower bed cover 12. The upper bed cover 11 and the lower bed cover 12 may be detachably connected to one another. For example, the detachable connection method may be zippers, buttons, pattern stickers, etc. The upper bed cover 11 and the lower bed cover 12 cooperate to form an openable inner cavity, and the first support bar 40, the air pump 100 and the two inflatable bladders 20 may be positioned in the inner cavity.

[0154] As shown in FIG. 2, two inflatable bladders 20 may be arranged side by side in the width direction of the inflatable mattress. By arranging two independent inflatable bladders 20 next to each other, neither inflatable bladder 20 may affect the other while the inflatable mattress is in use. For example, motion generated by a user repositioning themselves on one inflatable bladder 20 may be minimally transferred to the other inflatable bladder 20 by having separate inflatable bladders 20. Additionally, inflatable bladders 20 may be set to different softness and hardness, i.e., firmness, making the inflatable mattress more rigid.

[0155] Referring to FIG. 3, a side wall of each inflatable bladder 20 may be provided with an inflation and deflation interface 21. Compared with the air pump 100 being embedded in the inflatable bladder 20, the inflation and deflation interface 21 occupies a smaller space in the inflatable bladder 20. In embodiments, the inflation and deflation interface 21 may also be connected to the inflatable bladder 20, such as through a conduit coupled to the inflatable bladder 20. The inflatable bladder 20 may be formed in one piece, which is convenient for manufacturers to produce.

[0156] An air pump, illustratively air pump 100, may be provided with a first inflation port 101 and a second inflation port 102 that are independent of each other. The first inflation port 101 may be connected to the inflation and deflation interface 21 of one of the inflatable bladders 20, and the second inflation port 102 may be connected to the inflation and deflation interface 21 of the other inflatable bladder 20. In the illustrated embodiment, the inflation and deflation interface 21 is provided on a side wall in the width direction of the inflatable bladder 20. With this arrangement, the air pump 100 may be placed at the head or foot of the inflatable mattress, making it less likely to interfere with users. However, the inflation and deflation interface 21 may also be positioned on a side wall in the length direction of the inflatable bladder 20.

[0157] As shown in FIGS. 1 and 2, the air pump 100 may be installed and supported through the first support bar 40. The first support bar 40 may be provided with a throughmounted mounting hole 41 (see FIG. 3). The air pump 100 may be embedded in the mounting hole 41 such that the air pump 100 does not protrude from the mounting hole 41. For example, panel 120 may be flush with a surface 43 of support bar 40 or recessed within mounting hole 41 relative to surface 43 of support bar 40. The first support bar 40 may protect the air pump 100. The first support bar 40 may be disposed against the side wall of the inflatable bladder 20 where the inflation and deflation interface 21 is provided. Additionally, a window exposing the air pump 100 may be provided on the bed cover 8 to facilitate control of the air pump 100.

[0158] The first support bar 40 may be made of sponge or foam-like material. To prevent the arrangement of the first support bar 40 from being obtrusive, the height of the first support bar 40 may be adapted to the height of the inflatable bladder 20 when fully inflated, and the length of the first support bar 40 may be adapted to the sum of the widths of all the inflatable bladders 20. The provision of the first support bar 40 may also reduce the depression of the side edge of the inflatable mattress where the first support bar 40 is provided.

[0159] Now turning to FIGS. 4-5, another embodiment of an inflatable mattress is shown. The inflatable mattress of FIGS. 4-5 is substantially identical to the inflatable mattress of FIGS. 1-3 except for partition bar 50, which is disposed between the two inflatable bladders 20. Partition bar 50 may act as a spacer between adjacent inflatable bladders 20. The length of the partition bar 50 may match the length of the inflatable bladder 20. Similarly, the height of the partition bar 50 may match the height of the inflatable bladder 20 when the inflatable bladder is inflated. By providing the partition bar 50, the friction between the two inflatable bladders 20 may be reduced, which may mitigate noise generated by a user repositioning themselves on one of the inflatable bladders 20. The partition bar 50 may further suppress motion being transferred from one inflatable bladder 20 to the other when a user repositions themselves on the inflatable mattress. Like first support bar 40, the partition bar 50 may be made of sponge or foam-like material and may support the middle of the air mattress.

[0160] FIGS. 6-7 depict another embodiment of an inflatable mattress according to the present disclosure. The inflatable mattress of FIGS. 6-7 is substantially identical to the inflatable mattress of FIGS. 4-5 except for second support bar 60, which is positioned at a head or a foot of the inflatable mattress opposite support bar 40. The second support bar 60 is disposed against the side wall of the inflatable bladder 20 in the other width direction. The arrangement of the second support bar 60 may make the structure of the air mattress more symmetrical and reduce the depression of the corresponding side of the air mattress under pressure.

[0161] FIG. 8 depicts another embodiment of an inflatable mattress according to the present disclosure. As shown in FIG. 8, the difference between the illustrated embodiment and the embodiment of FIGS. 6-7 is that the air mattress of FIG. 8 also includes two third support bars 70. The length direction of the third support bars 70 may be parallel to the length direction of the inflatable bladder 20. In the illustrated embodiment, third support bars 70 are disposed along an external length side of the inflatable bladders 20. Once assembled, the third support bars 70 may abut against the side wall of the adjacent inflatable bladder 20. The height of the third support bar 70 may be adapted to the height of the inflatable bladder 20, and the length of the third support bar 70 may be adapted to the length of the inflatable bladder 20. Accordingly, in this embodiment, first support bar 40, second support bar 60, and third support bars 70 cooperate to support all four sides of the air mattress. The edge of the bed may not be easily deformed due to force. Like first support bar 40 and second support bar 60, third support bars 70 may be formed of a sponge or foam-like material that may reduce noise and absorb movement generated by the user.

[0162] FIG. 9 depicts another embodiment of an inflatable mattress according to the present disclosure. As shown in FIG. 9, the difference between the embodiment of FIG. 9 and the embodiment of FIG. 8 is that only one inflatable bladder 20 is provided. Accordingly, partition bar 50 may eliminated.

[0163] The present disclosure provides an inflation and deflation interface 21 on the inflatable bladder 20. Through inflation and deflation interface 21, air pump 100, which is positioned outside of the inflatable bladder 20, may inflate or deflate the inflatable bladder 20, thereby regulating pressure within the inflatable bladder 20 and allowing the user to adjust the firmness of the inflatable mattress. Additionally, the air pump 100 may be installedthrough the support bar 40, which is disposed against the side wall of the inflatable bladder 20. Disposing support bar 40 against the side wall of the inflatable bladder 20 may help support air pump 100, thereby improving installation stability. Further, by positioning air pump 100 as discussed herein, the air pump 100 may not interfere with the use of the inflatable bladder 20. By placing the air pump 100 outside of the inflatable bladder 20, the connection between the air pump 100 and the inflatable bladder 20 is more convenient, and the operation is simple and may be completed without the need for professionals, which is convenient for maintenance and after-sales service.

[0164] Having described embodiments of inflatable mattresses of the present disclosure, air pump 100, introduced above, will now be described in detail with reference to FIGS. 10- 13.

[0165] As shown in FIGS. 10-13, air pump 100 may include, among other features, a pressure detection assembly. The pressure detection assembly may include an inflation and deflation joint 150 (see FIG. 11), at least one pressure sensor 173 (see FIG. 12), and at least one pressure detection tube 165 coupled to the inflation and deflation joint 150 and in communication with the pressure sensor 173.

[0166] The inflation and deflation joint 150 may be formed with an inflation and deflation channel 151 (see FIG. 11) and a pressure detection channel 161. Both the inflation and deflation channel 151 and the pressure detection flow channel 161 may be in fluid communication with the inflatable bladder 20 of the inflatable mattress. As will be described further herein, for an inflatable mattress including two inflatable bladders 20, such as the inflatable mattress depicted in FIG. 2, two inflation and deflation joints 150 may be provided (see FIG. 12), each of which may include an inflation and deflation flow channel and a pressure detection channel.

[0167] Referring to FIG. 11, at least part of the pressure detection channel 161 may be parallel to the inflation and deflation channel 151. One end of the pressure detection conduit 165 may be operably coupled to the pressure sensor 173, and the other end may be coupled to the pressure detection channel 161 of inflation and deflation joint 150. Inflation and deflation joint 150 may include a pressure detection interface 163 that receives the end of pressure detection conduit 165 that is coupled to the inflation and deflation joint 150. Throughpressure detection channel 161, the pressure detection conduit 165, and therefore pressure sensor 173, may be in fluid communication with inflatable bladder 20.

[0168] Because pressure detection channel 161 may be integrally formed with the inflation and deflation joint 150, the pressure detection conduit 165 may not extend from air pump 100. Thus, the pressure detection assembly for air pump 100 may be simplified, and installation and use of air pump 100 may be more convenient.

[0169] Additionally, because the pressure detection channel 161 is parallel to the inflation and deflation channel 151, pressure sensor 173 may more accurately measure air pressure within inflatable bladder 20. When air pump 100 is in the initial stage of inflation, air quickly enters the inflatable bladder 20 through inflation and deflation channel 151 and a negative pressure will form at the opening of the pressure detection channel 161. The pressure detection channel 161 will not receive airflow directly from air pump 100, which would interfere with pressure sensor 173 and cause pressure sensor 173 to register an inaccurate air pressure measurement for inflatable bladder 20. As the air pressure in inflatable bladder 20 increases, the inflation and deflation joint 150 will be subject to back pressure from the inflatable bladder 20. At this time, air pressure may be detected in the pressure detection channel 161. Through pressure detection channel 161 and pressure detection conduit 165, the pressure sensor 173 may accurately detect the air pressure within the inflatable bladder 20. The pressure detection assembly of the present disclosure minimizes interference of airflow through inflation and deflation channel 151 with pressure sensor 173 to ensure that the pressure sensor 173 accurately detects the pressure within the inflatable bladder 20.

[0170] One end of the pressure detection channel 161 may be coupled to pressure detection conduit 165, and the other end of pressure detection channel 161 may be in fluid communication with the inside of inflatable bladder 20. One end of the inflation and deflation channel 151 may be in fluid communication with airflow generating components inside air pump 100, and the other end of inflation and deflation channel 151 may be in fluid communication with inflatable bladder 20. During inflation, inflation and deflation channel 151 may communicate airflow from air pump 100 to the interior of inflatable bladder 20. The entire pressure detection channel 161 may be parallel to the inflation and deflation channel 151, or, as shown in the illustrated embodiment, part of pressure detection channel 161 maybe parallel to the inflation and deflation channel 151. When part of pressure detection channel 161 is parallel to the inflation and deflation channel 151, the parallel portion of pressure detection channel 161 may be arranged in close proximity to the inflation and deflation channel 151 of inflation and deflation joint 150. Due to the construction of the pressure detection assembly, pressure sensor 173 may accurately determine air pressure within inflatable bladder 20 though pressure detection channel 161, which is disposed near inflation and deflation channel 151.

[0171] The pressure detection assembly of the present disclosure may be applied to different types of air pumps, such as air pumps configured to inflate an inflatable product, air pumps configured to both inflate and deflate an inflatable product, single-channel air pumps, multi-channel air pumps, etc. The illustrated embodiment depicts a dual-channel inflation and deflation air pump 100. Referring to FIGS. 11-13, air pump 100 may be provided with two inflation and deflation joints 150 corresponding to two inflatable bladders 20.

[0172] Air pump 100 may include a body 110, a control panel 120 coupled to body 110 (see FIG. 13), a control circuit board 171 installed inside the body 110, and an inflation and deflation assembly installed inside the body 110. A panel 120 (see FIG. 10) is a lid which cooperates with body 110 to define an interior and may include vents (not shown) which allow the interior to be in fluid communication with atmosphere. As shown in FIG. 12, the pressure sensor 173 may be installed on the control circuit board 171. The pressure detection conduit 165 may also be arranged in the body 110.

[0173] Referring to FIG. 12, the inflation and deflation assembly of air pump 100 may include an air pump assembly 130 and an air passage switch assembly 140. Air pump assembly 130 may be used to inflate or deflate inflatable bladder 20. The air passage switch assembly 140 may be disposed between the air pump assembly 130 and the inflation and deflation joints 150 and operable to fluidly connect or disconnect one or more inflation and deflation joints 150 with air pump assembly 130 and hence one or more of inflatable bladders 20 with air pump assembly 130.

[0174] As shown in FIG. 12, air pump assembly 130 may include a pump cover 131, an impeller 133, a pump body 135, and a motor 137 operably coupled to the impeller 133 and configured to drive impeller 133 to rotate. Air pump assembly 130 may include a pump inlet 139 in fluid communication with atmosphere and a pump outlet in selective fluidcommunication with inflatable bladder(s) 20 through air passage switch assembly 140. In the illustrated embodiment, for example, pump cover 131 includes a pump inlet 139, and pump cover 131 and pump body 135 together define a pump outlet 129 (see FIG. 15).

[0175] The pump cover 131 may be coupled to the pump body 135, and together pump cover 131 and pump body 135 may cooperate to define an impeller chamber in fluid communication with atmosphere and selective fluid communication with inflatable bladder(s) 20. Impeller 133 may be disposed in the impeller chamber and operably coupled to the motor 137, which is positioned outside the impeller chamber. When the motor 137 is started, it drives the impeller 133 to rotate, thereby drawing air from atmosphere through the pump inlet 139 into the impeller chamber and then expelling air through the pump outlet 129 into the inflatable bladder(s) 20 to inflate the inflatable product. Alternatively, the air pump assembly 130 may draw in air from the inflatable bladder(s) 20 and expel air to atmosphere to deflate the inflatable product.

[0176] Still referring to FIG. 12, air passage switch assembly 140 may include a switching motor 141, an upper pump cover 145, a turntable 147, and a valve seat 149. The upper pump cover 145 may be coupled to the valve seat 149, and the turntable 147 may be rotatably positioned between the upper pump cover 145 and the valve seat 149. In the illustrated embodiment, the switching motor 141 is disposed above the upper pump cover 145 and operably coupled to the turntable 147through transmission gear 143. Specifically, switching motor 141 may include a driven shaft (not shown) operably coupled to transmission gear 143, which meshes with turntable 147 such that rotation of the driven shaft is transferred to turntable 147. Thus, switching motor 141 may drive the turntable 147 to rotate. As will be explained further herein, rotation of the turntable 147 may close or open the inflation and deflation joints 150.

[0177] In the illustrated embodiment, the inflation and deflation joint 150 is integrally formed with valve seat 149 of the air passage switch assembly 140. The inflation and deflation joint 150 may be fixed on the bottom of the body 110, and one end of the inflation and deflation joint 150 may be positioned in the body 110 and cooperate with the air pump assembly 130. The other end of the inflation and deflation joint 150 may pass through the bottom of the body 110 and extend outside the body 110. In other embodiments, the inflationand deflation joint 150 may be integrally formed with body 110, such as by monolithically forming the inflation and deflation joints 150 on the main body 110 as a single structure.

[0178] Referring to FIG. 13, to facilitate quick connection between the inflation and deflation joint 150 and the inflation and deflation pipe 183, the inflation and deflation joint 150 may be equipped with a quick connector 181, which is received by inflation and deflation pipe 183. Quick connector 181 may include a lock 174 pivotally mounted in a recess 175. Lock 174 is biased by a spring 176 such that tabs 177 are received in a recess 178 (see FIG. 11) of the inflation and deflation joint 150 to maintain the quick connector 181 in a locked configuration relative to the inflation and deflation joint 150. Inflation and deflation pipe 183 may be coupled to a connector 187 that may in turn be coupled to the inflation and deflation interface 21 of a respective inflatable bladder 20. Connector 187 may be coupled to inflation and deflation interface 21 of inflatable bladder 20 by welding, gluing, or otherwise adhering so long as the seal is fluid tight to prevent air leaking from the inflatable bladder 20.

[0179] Still referring to FIG. 13, a protective cover 185 may be coupled to the bottom of the body 110, and the quick connector 181 may be disposed within the protective cover 185. One end of the inflation and deflation pipe 183 may be disposed within the protective cover 185 and coupled to the quick connector 181, and the other end may extend out of the protective cover 185 and couple to the connector 187 (see FIG. 15).

[0180] The present disclosure provides a pressure detection channel 161 formed with the inflation and deflation joint 150 so that the pressure detection tube 165 does not extend out of air pump 100. Thus, the pressure detection assembly of the air pump 100 is simplified. The air pump 100 is more convenient to install and use. Because the pressure detection channel 161 may be parallel to the inflation and deflation channel 151, when the air pump 100 is in the initial stage of inflation, air may quickly enter the inflatable product through the inflation and deflation channel 151, and a negative pressure will form at the opening of the pressure detection channel 161. During initial stages of inflation, airflow from the air pump assembly 130 will not be received by the pressure detection channel 161, which would interfere with the pressure sensor 173. As the air pressure in the inflatable product gradually increases, the inflation and deflation joint 150 will be subject to back pressure from the inflatable bladder 20. At this time, pressure within inflatable bladder 20 may be measured by pressure sensor 173 through pressure detection conduit 165 and pressure detection channel 161 withoutinterference of airflow from air pump assembly 130 through inflation and deflation channel 151. Therefore, the present disclosure ensures that the pressure sensor 173 accurately detects the pressure within the inflatable product.

[0181] In addition to accurately determining pressure within inflatable bladder 20 using the above-described air pressure detection assembly, air pump 100 may also be configured to perform fine-tuning inflation and deflation to incrementally adjust the pressure within inflatable bladder 20.

[0182] Referring to FIGS. 12 and 15-25, the present disclosure provides an air pump 100 configured to fine-tune pressure within inflatable bladder 20. As previously discussed, air pump 100 may include a control circuit board 171, an air pump assembly 130, and an air passage switch assembly 140 arranged in the body 110. The air pump assembly 130 and the air passage switch assembly 140 may be operably coupled to the control circuit board 171, which may control air pump assembly 130 and air passage switch assembly 140 with electrical control signals.

[0183] As introduced above, air passage switch assembly 140 may include a driving component, a turntable 147 operably coupled to the driving component, a valve seat 149, and a switch 148. The driving component may include switching motor 141 and transmission gear 143, which is operably coupled to switching motor 141 such that switching motor 141 may drive transmission gear 143 to rotate. Switch 148 may be an optocoupler detector or other type of non-contact switch. In the illustrated embodiment, switching motor 141 and switch 148 are disposed in the body 110 and are operably coupled to the control circuit board 171. In the illustrated embodiment, switching motor 141 and switch 148 are coupled to upper pump cover 145. Switching motor 141 may be operably coupled to turntable 147 through transmission gear 143 to drive turntable 147 to rotate. For example, transmission gear 143 may mesh with turntable 147. Turntable 147 may be closely fitted beneath air pump assembly 130 and may be in selective fluid communication with the impeller chamber of the air pump assembly 130. As explained herein, turntable 147 may include a plurality of features, illustratively tabs, which switch 148 may detect to determine a location of turntable 147. In embodiments, a location of turntable 147 is known based on an encoder that tracks a position of switching motor 141.

[0184] Turntable 147 may include a plurality of openings extending therethrough and lands between the plurality of openings. Referring to FIG. 17, in the illustrated embodiment, turntable 147 is provided with an inflation and deflation opening 441 and two fine-tuning openings 442, 443 disposed on opposing sides of inflation and deflation opening 441. Fine- tuning openings 442, 443 may have a smaller diameter than inflation and deflation opening 441. Further, turntable 147 may include at least three, illustratively five, locator tabs on the outer periphery of turntable 147 that cooperate with switch 148 to communicate to control circuit board 171 the position of turntable 147. Turntable 147 may be integrally formed with a groove 155 disposed opposite inflation and deflation opening 441. Groove 155 may extend partially into a depth of turntable 147 and may balance turntable 147 as turntable 147 rotates under the driving force of switching motor 141.

[0185] Referring to FIG. 16, valve seat 149 is closely fitted beneath turntable 147, and valve seat 149 may be provided with at least one inflation and deflation channel 151. In the illustrated embodiment, valve seat 149 is provided with two inflation and deflation channels 151, 153 corresponding to a dual-chamber inflatable product. In the illustrated embodiment, the top side of valve seat 149 faces turntable 147, and the underside of valve seat 149 extends outside of body 110. As described above, valve seat 149 may be integrally formed with inflation and deflation joint 150, and together valve seat 149 and inflation and deflation joint 150 may define first and second inflation and deflation channels 151, 153.

[0186] As depicted in FIG. 17, turntable 147 includes a first locator tab 444, a second locator tab 445, and a third locator tab 446. In operation, switching motor 141 drives turntable 147 to rotate relative to air pump assembly 130 and valve seat 149, and switch 148 detects first locator tab 444, second locator tab 445, etc., as turntable 147 rotates. Each locator tab, e.g., first locator tab 444, corresponds to an operation of air pump 100. Referring to FIGS. 16 and 17, when switch 148 detects the first locator tab 444, the inflation and deflation opening 441 of turntable 147 fluidly communicates the impeller chamber with the inflation and deflation channel 151 and air pump 100 may inflate or deflate a first inflatable bladder 20. Referring to FIGS. 18 and 19, when switch 148 detects second locator tab 445, fine-tuning opening 442 of turntable 147 fluidly communications the impeller chamber with the inflation and deflation channel 151, and air pump 100 may fine-tune the air pressure within the first inflatable bladder 20. Referring to FIGS. 24 and 25, when switch 148 detectsthe third locator tab 446, inflation and deflation opening 441 and fine-tuning openings 442, 443 are staggered relative to first and second inflation and deflation channels 151, 153 such that turntable 147 fluidly seals the impeller chamber from the inflation and deflation channels 151, 153 of valve seat 149. This may be considered a closed configuration of air pump 100.

[0187] Referring to FIGS. 12 and 25, in the illustrated embodiment, third locator tab 446 is approximately twice the width of first and second locator tabs 444, 445, and switch 148 includes two switches. When turntable 147 is in the closed position, third locator tab 446 may close both switches of switch 148. For example, third locator tab may simultaneously close both switches of switch 148.

[0188] Referring to FIGS. 20-23, turntable 147 may further include fourth locator tab 447 and fifth locator tab 448. As depicted in FIGS. 20 and 21, when switch 148 detects fifth locator tab 448, the inflation and deflation opening 441 of turntable 147 fluidly communicates the impeller chamber with inflation and deflation channel 153. Referring to FIGS. 22 and 23, when switch detects fourth locator tab 447, fine-tuning opening 443 of turntable 147 fluidly communicates the impeller chamber with inflation and deflation channel 153, and air pump 100 may fine-tune the air pressure within the inflatable bladder 20.

[0189] Accordingly, referring to FIGS. 17, 19, 21, 23, and 25, turntable 147 may be provided with fine-tuning openings 442, 443, which may be positioned on opposing sides of inflation and deflation opening 441, and turntable 147 may include corresponding locator tabs 445, 447 that, when detected by switch 148, cause switch 148 to signal to control circuit board 171 that turntable 147 is positioned to fine-tune pressure within the inflatable product through either first inflation and deflation channel 151 or second inflation and deflation channel 153, depending on whether switch 148 detects locator tab 445 or 447. When air pump 100 fluidly communications the inflation and deflation channels 151, 153 with the impeller chamber through the inflation and deflation opening 441 on the turntable 147, air pump 100 may inflate or deflate inflatable bladder 20.

[0190] During inflation or deflation of the inflatable product, i.e., inflatable bladders 20, the pressure detection assembly discussed above may detect a difference between the internal pressure of the inflatable product, the respective inflatable bladders 20, and the preset, i.e., desired, pressure. In response to this determination, control circuit board 171 may activateswitching motor 141 to drive turntable 147 to rotate until switch 148 detects, for example, second locator tab 445. Switch 148 sends a signal to control circuit board 171 when switch 148 detects locator tab 445, and control circuit board 171 deactivates switching motor 141. Switching motor 141 then stops driving turntable 147 to rotate so that the fine-tuning opening 442 of turntable 147 is aligned with inflation and deflation channel 151 (see FIG. 18), thereby opening inflation and deflation channel 151. When fine-tuning opening 442 is aligned with inflation and deflation channel 151, the impeller chamber is in fluid communication with inflation and deflation channel 151 through the fine-tuning opening 442 of turntable 147. Air pump 100 may then inflate or deflate the inflatable bladder 20 through the fine-tuning hole 442 to finely adjust the internal pressure of the inflatable product. A similar process is repeated if fine-tuning through inflation and deflation channel 153 is desired. Accordingly, air pump 100 may accurately control the internal pressure of the inflatable product.

[0191] Referring to FIG. 10, main body 110 may be coupled to control panel 120.Control panel 120 may be provided with user actuated control inputs, illustratively operation buttons, that enable the user to control operation of air pump 100. For example, control panel 120 may include a power button 1201, an inflation button 1203, a deflation button 1205, a first-chamber pressure adjust button 1207, and a second-chamber pressure adjust button 1209, each of which communicates with control circuit board 171 to control operation of air pump 100. The user may control air pump 100 to inflate, deflate, or adjust pressure within a select chamber, e.g., inflatable bladders 20, by operating the user actuated control inputs. Control panel 120 may also include visual indicators, such as lights 1211, that indicate to the user firmness of a corresponding inflatable bladder 20. For example, lights 1211 may correspond to low, medium, and high firmness of the corresponding inflatable bladder 20.

[0192] Referring to FIGS. 16-24, the illustrated valve seat 149 and body 110 are separate components, and the valve seat 149 is provided with two inflation and deflation channels, namely a first inflation and deflation channel 151 and a second inflation and deflation channel 153. As discussed above, in alternative embodiments valve seat 149 and body 110 may be monolithically formed as a single component.

[0193] Referring to FIGS. 16-25, turntable 147 may be provided with two fine-tuning openings, namely first fine-tuning opening 442 and second fine-tuning opening 443. In the31illustrated embodiment, first fine-tuning opening 442 and second fine-tuning opening 443 are respectively provided on opposing sides of the inflation and deflation opening 441. Five locator tabs 444, 445, 446, 447, and 448 may be provided on the periphery of turntable 147 and arranged in clockwise or counterclockwise order. Referring to FIGS. 16 and 17, while switching motor 141 drives the turntable 147 to rotate, when switch 148 detects the first locator tab 444, the inflation and deflation opening 441 of turntable 147 fluidly communicates the impeller chamber with the first inflation and deflation channel 151. In this configuration, air pump 100 may inflate or deflate inflatable bladder 20 through inflation and deflation channel 151. Referring to FIGS. 18 and 19, when switch 148 detects second locator tab 445 of turntable 147, fine-tuning opening 442 of the turntable 147 may fluidly communicate the impeller chamber with the inflation and deflation channel 151 to fine-tune the pressure within inflatable bladder 20. Referring to FIGS. 24 and 25, when switch 148 detects third locator tab 446 of turntable 147, turntable 147 fluidly seals the impeller chamber from the inflation and deflation channels 151, 153. This may be considered a closed configuration for air pump 100. Referring to FIGS. 22 and 23, when switch 148 detects fourth locator tab 447, fine-tuning opening 443 of the turntable 147 may fluidly communicate the impeller chamber with the second inflation and deflation channel 153 to fine-tune the pressure within a second inflatable bladder 20. Lastly, referring to FIGS. 20 and 21, when switch 148 detects fifth locator tab 448, inflation and deflation opening 441 of turntable 147 fluidly communicates the impeller chamber with the second inflation and deflation channel 153 to inflate or deflate the second inflatable bladder 20.

[0194] Accordingly, the dual-channel air pump 100 of the present disclosure may finetune the pressure of a first inflatable bladder 20 through the first inflation and deflation channel 151 and first-tuning opening 442 of turntable 147 and may fine-tune a second inflatable bladder 20 through the second inflation and deflation channel 153 and second fine- tuning opening 443. Thus, if the above-described pressure detection assembly determines that the pressure within inflatable bladder 20 has exceeded or fallen below the preset, i.e., desired, pressure, air pump 100 can perform fine-tuning inflation or deflation to correct the pressure within inflatable bladder 20.

[0195] Having described the structure of air pump 100, operation of air pump 100 will now be discussed with reference to FIGS. 16-24.

[0196] Press inflation button 1203 on control panel 120, which may be operably coupled to control circuit board 171, to activate air pump motor 137 and switching motor 141. Switching motor 141 drives turntable 147 to rotate until switch 148 detects first locator tab 444. Upon detection of first locator tab 444, switch 148 signals to control circuit board 171 to deactivate switching motor 141. Referring to FIGS. 16 and 17, when turntable 147 is in this position, the inflation and deflation opening 441 of turntable 147 fluidly communicates the impeller chamber with the first inflation and deflation channel 151. Airflow generated by the air pump motor 137 may enter the impeller chamber from atmosphere and then pass through the inflation and deflation hole 441 of turntable 147 before entering the first inflation and deflation channel 151 and finally the inflatable bladder 20 through the inflation and deflation pipe 183, thereby inflating the air chamber.

[0197] When pressure sensor 173 detects that inflatable bladder 20 has reached the set pressure, switching motor 141 may drive turntable 147 to rotate until switch 148 detects fifth locator tab 448 of turntable 147. Upon detection of fifth locator tab 448, switch 148 signals to control circuit board 171 to deactivate switching motor 141. Referring to FIGS. 20 and 21, when turntable 147 is in this position, inflation and deflation opening 441 of turntable 147 fluidly communicates the impeller chamber with the second inflation and deflation channel 153. Air pump 100 may inflate the second inflatable bladder 20. Thus, air pump 100 may sequentially inflate first and second inflatable bladders 20. This step is omitted for a singlebladder inflatable product.

[0198] When pressure sensor 173 detects that the second inflatable bladder 20 has reached the set pressure (or the first inflatable bladder 20 has reached the set pressure for a single-bladder inflatable product), switching motor 141 drives turntable 147 to rotate until switch detects third locator tab 446. Referring to FIGS. 24 and 25, when turntable 147 is positioned such that switch 148 detects third locator tab 446, inflation and deflation opening 441 and fine-tuning openings 442, 443 are staggered relative to first and second inflation and deflation channels 151, 153, cutting off fluid communication between the impeller chamber and the inflation and deflation channels 151, 153. Control circuit board 171 deactivates air pump motor 137 and switching motor 141, and rapid inflation of inflatable bladder(s) 20 is completed.

[0199] Since the airflow generated by the air pump assembly 130 is large, it may be difficult to accurately control pressure within inflatable bladder 20 when inflating the inflatable bladder 20. When the actual pressure in the inflatable bladder 20 is greater than the set, i.e., desired, value, switching motor 141 may be reversed to drive turntable 147 to rotate until second locator tab 445 (or the fourth locator tab 447) trigger switch 148. In this position, first fine-tuning opening 442 (or second fine-tuning opening 443) of turntable 147 fluidly communications the impeller chamber with the corresponding inflation and deflation channels 151, 153, and air pump 100 adjusts pressure within the respective inflatable bladder 20. Once the pressure sensor 173 detects that the set pressure has been reached, control circuit board 171 activates switching motor 141 to drive turntable 147 to the closed position.

[0200] To perform fine-tuning deflation of inflatable bladder 20, control circuit board 171 activates pump motor 137 and switching motor 141. Switching motor 141 drives turntable 147 to rotate until switch 148 detects second locator tab 445 (or fourth locator tab 447). When switch 148 detects second locator tab 445 (or fourth locator tab 447), switch 148 communicates with control circuit board 171, which deactivates switching motor 141, and turntable 147 stops rotating. In this position, first fine-tuning opening 442 (or second fine- tuning opening 443) of turntable 147 fluidly communicate the impeller chamber with the corresponding inflation and deflation channel 151, 153. The air pump assembly may deflate inflatable bladder 20 to the preset pressure. When pressure sensor 173 detects that the preset pressure has been reached within inflatable bladder 20, control circuit board 171 activates switching motor 141 to drive turntable 147 to the closed position and deactivates pump motor 137. Alternatively, to perform fine-tuning deflation of inflatable bladder 20, switching motor 141 may drive turntable 147 to the corresponding position wherein fine-tuning opening 442 is aligned with inflation and deflation channel 151 or fine-tuning opening 443 is aligned with inflation and deflation channel 153 and the corresponding inflatable bladder 20 may vent directly to atmosphere without activation of pump motor 137. Air pump 100 may automatically perform fine-tuning deflation. For example, pressure sensor 173 may detect that the pressure within inflatable bladder 20 exceeds the set pressure, and control circuit board 171 may initiate fine-tuning deflation. Alternatively, air pump 100 may perform fine- tuning deflation in response to user actuation of first-chamber pressure adjustment control 1207 or second-chamber pressure adjustment control 1209 (FIG. 10).

[0201] To perform fine-tuning inflation of inflatable bladder 20, control circuit board 171 activates air pump motor 137 and switching motor 141. Switching motor 141 drives the turntable 147 to rotate until switch 148 detects second locator tab 445 (or fourth locator tab 447). When switch 148 detects second locator tab 445 (or fourth locator tab 447), switch 148 communicates with control circuit board 171, and control circuit board 171 deactivates switching motor 141 and turntable 147 stops rotating. In this position, first fine-tuning opening 442 (or second fine-tuning opening 443) of turntable 147 fluidly communicate the impeller chamber with the inflation and deflation channels 151, 153. The air pump assembly 130 inflates inflatable bladder 20 until pressure sensor 173 detects that the preset pressure has been reached, at which point control circuit board 171 activates switching motor 141 to drive turntable 147 to the closed position and deactivates pump motor 137. Air pump 100 may automatically perform fine-tuning inflation. For example, pressure sensor 173 may detect that the pressure within inflatable bladder 20 is below the set pressure, and control circuit board 171 may initiate fine-tuning inflation. Alternatively, air pump 100 may perform fine- tuning inflation in response to user actuation of first-chamber pressure adjustment button 1207 or second-chamber pressure adjustment control 1209 (FIG. 10).

[0202] To fully deflate inflatable bladder 20, control circuit board 171 activates switching motor 141 to drive turntable 147 to rotate until switch 148 detects first locator tab 444 (or fifth locator tab 448). In this position, inflation and deflation opening 441 of turntable 147 is aligned with inflation and deflation channel 151 (or inflation and deflation channel 153) and fluidly communicates the impeller chamber with inflation and deflation channel 151 (or inflation and deflation channel 153). The corresponding inflatable bladder 20 may vent to atmosphere. In embodiments, control circuit board 171 may also activate pump motor 137 to draw air from inflatable bladder 20 and expel air to atmosphere. Air pump 100 may fully deflate inflatable bladder 20 in response to user actuation of deflation button 1205 (FIG. 10).

[0203] Although air passage switch assembly 140 is shown with a dual-chamber air pump, air passage switch assembly 140 may also be incorporated into an air pump for a single-chamber or three-chamber inflatable product.

[0204] The present disclosure provides an air passage switch assembly including a turntable 147 having an inflation and deflation opening 441, fine-tuning openings 442, 443 and corresponding locator tabs 444, 445, 447, and 448. When air pump 100 fluidlycommunicates the inflation and deflation channels 151, 153 with the impeller chamber through the inflation and deflation opening 441 of the turntable 147, air pump 100 may inflate or deflate inflatable bladder 20. If there is a difference between the internal pressure of the inflatable bladder 20 and the preset pressure, turntable 147 is driven to rotate by switching motor 141 and transmission gear 143 until switch 148 detects second locator tab 445 (or fourth locator tab 447). When switch 148 detects second locator tab 445 (or fourth locator tab 447), switch 148 signals to control circuit board 171 that turntable 147 is properly oriented for fine-tuning operations. Control circuit board 171 deactivates switching motor 141, and turntable 147 stops rotating. In this position, fine-tuning opening 442 (or fine-tuning opening 443) of the turntable 44 are in fluid communication with the inflation and deflation channels 151, 153. Inflation and deflation channels 151, 153 may be in fluid communication with the impeller chamber, and then inflated or deflated through the fine-tuning openings 442, 443, thereby achieving fine adjustment of the internal pressure of the inflatable product. Thus, air pump 100 can accurately control the internal pressure of the inflated product.

[0205] FIGS. 26-35 depict another embodiment of an air pump 100’ according to the present disclosure. Air pump 100 and air pump 100’ share structural similarities, with like reference numerals corresponding to like components. Differences between air pump 100 and air pump 100’ will now be discussed in detail with reference to FIGS. 26-35.

[0206] Referring to FIGS. 26 and 27, air pump 100’ may include a body 110, a control panel 120 coupled to body 110, a supplemental air pump assembly 230, a solenoid valve assembly 250, and a main air pump assembly 130 disposed in the body 110. Body 110, control panel 120, and main air pump 130 of air pump 100’ are substantially identical to the corresponding components of air pump 100 and will not be further described. Air pump 100’ may also include an air passage switch assembly 140’ and control circuit board 171. The air passage switch assembly 140’, supplemental air pump assembly 230, solenoid valve assembly 250, and main pump assembly 130 may be operably coupled to the control circuit board 171. Like air pump 100, air pump 100’ may include a pressure detection assembly including a pressure sensor 173 and pressure detection tube 165 in fluid communication with an inflatable bladder 20. Valve seat 149’ may include pressure detection interfaces 163 configured to couple to pressure detection tubes 165.

[0207] Referring to FIG. 27, air passage switch assembly 140’ may include a driving assembly, a turntable 147’ operably coupled to the driving assembly, and a valve seat 149’. The driving assembly may be operably coupled to the control circuit board 171. Turntable 147’ may be rotatably disposed on valve seat 149’ and disposed below the main air pump assembly 130. Turntable 147’ may include an inflation and deflation opening 441. In the illustrated embodiment, turntable 147’ includes two inflation and deflation openings 441 separated by lands. Valve seat 149’ may be tightly positioned below the turntable 147’ to create a fluid-tight seal therebetween. Valve seat 149’ may be provided with at least one inflation and deflation channel 151. In the illustrated embodiment, valve seat 149’ includes two inflation and deflation channels 151. As will be described further herein, inflation and deflation openings 441 are arranged on turntable 147’ such that turntable 147’ may simultaneously place both inflation and deflation channels 151 of valve seat 149’ in fluid communication with the impeller chamber of air pump assembly 130. However, inflation and deflation openings 441 may instead be positioned such that turntable 147’ may place inflation and deflation channels 151 in independent fluid communication with the impeller chamber of air pump assembly 130.

[0208] Referring to FIGS. 26 and 31 a side wall of each inflation and deflation channel 151 may be provided with a fine-tuning channel 751 in fluid communication with the inflation and deflation channel 151. As will be explained further herein, fine-tuning channels 751 may be in fluid communication with solenoid valve assembly 250 through fine-tuning conduit 255.

[0209] The driving assembly may be operably coupled to turntable 147’ and configured to drive turntable 147’ to rotate relative to valve seat 149’ and main air pump assembly 130. During rotation of turntable 147’, the impeller chamber of the main air pump assembly 130 and the inflation and deflation channels 151 of valve sear 149’ are either sealed relative to one another by turntable 147’ or in fluid communication through the inflation and deflation openings 441 of turntable 147’.

[0210] Referring to FIGS. 30-35, one end of the solenoid valve group 250 may be in fluid communication with the supplemental air pump assembly 230, and the other end may be in fluid communication with the fine-tuning channel 751 through fine-tuning conduit 255.

[0211] Air passage switch assembly 140’ may be used in conjunction with main air pump assembly 130 to quickly deflate or inflate an inflatable product. Air passage switch assembly 140’, supplemental air pump assembly 230, and solenoid valve assembly 250 cooperate to fine-tune the air pressure within an inflatable product, such as by performing fine-tuning inflation or deflation of the inflatable product. Alternatively, during fine-tuning deflation, air within inflatable bladder 20 may vent to atmosphere through solenoid valve group 250 without activation of supplemental air pump assembly 230. When inflation and deflation opening 441 of turntable 147’ fluidly communicates the impeller chamber of the main air pump assembly 130 with the inflation and deflation channel 151 of the valve seat 149’, main air pump assembly 130 may operate to quickly inflate or deflate the inflatable product. When turntable 147’ fluidly seals the impeller chamber of the main air pump assembly 130 from the inflation and deflation channel 151, supplemental air pump assembly 230 may operate in conjunction with solenoid valve assembly 250 to adjust, i.e., fine-tune, the air pressure within the inflatable product.

[0212] FIGS. 33 and 34 depict fine-tuning inflation and fine-tuning deflation operations. Referring to FIG. 33, supplemental air pump group 230 may draw in air from atmosphere through panel 120 expel air through solenoid valve group 250. From solenoid valve group 250, air may pass through fine-tuning conduit 255 and into fine-tuning channel 751 of valve seat 149’ before ultimately entering inflation and deflation channel 151 of valve seat 149’ to fine-tune the air pressure within the inflatable product. Alternatively, referring to FIG. 34, air within the inflatable product may enter inflation and deflation channel 151 and then flow through fine-tuning channel 751, fine-tuning conduit 255, solenoid valve group 250, and supplemental air pump assembly 230 before discharging from panel 120 to fine-tune the air pressure within the inflatable product. Thus, like air pump 100, air pump 100’ may also accurately control the internal air pressure of the inflatable product, such as inflatable bladders 20.

[0213] Air passage switch assembly 140’ is substantially similar to air passage switch assembly 140 except as provided herein. Referring to FIG. 27, to accurately control the rotation stroke of turntable 147’, air passage switch assembly 140’ may include switch 148 operably coupled to control circuit board 171. Switch 148 may be provided on one side of theturntable 147’. Switch 148 may be coupled to valve seat 149’. As described above, switch 148 may be a photocoupler detector.

[0214] Referring to FIG. 27, turntable 147’ may include a plurality of locator tabs that cooperate with switch 148 to signal to control circuit board 171 the position of turntable 147’. In the illustrated embodiment, turntable 147’ includes two locator tabs 444, 445. During operation, when switch 148 detects first locator tab 444, turntable 147’ may fluidly seal the impeller chamber of the main air pump assembly 130 from the inflation and deflation channels 151 of the valve seat 149’. When switch 148 detects second locator tab 445 of turntable 147’, the impeller chamber of main air pump assembly 130 and the inflation and deflation channel 151 of valve seat 149’ may be in fluid communication through the inflation and deflation opening 441 of the turntable 147’. If valve seat 149’ has one or two inflation and deflation channels 151, then turntable 147’ may include at least two locator tabs. If the valve seat 149’ has more than two inflation and deflation channels 151, then the turntable 147’ may include at least three locator tabs. Thus, the number of locator tabs may increase to accommodate a greater number of inflation and deflation channels 151. Although the illustrated embodiment includes two inflation and deflation openings 441 and locator tab 445 arranged to simultaneously place the impeller chamber of air pump assembly 130 in communication with inflation and deflation channels 151 of valve seat 149’, turntable 147’ may include inflation and deflation openings 441 arranged to provide independent fluid communication between the impeller chamber of air pump assembly 130 and inflation and deflation channel 151 of valve seat 149’. In the latter exemplary embodiment, turntable 147’ may include an additional locator tab 445 such that the first locator tab 445 is configured to indicate when a first inflation and deflation opening 441 is in fluid communication with a first inflation and deflation channel 151, and a second locator tab 445 is configured to indicate when a second inflation and deflation opening is in fluid communication with a second inflation and deflation channel 151.

[0215] In the illustrated embodiment (see FIG. 31), valve seat 149’ is provided with two inflation and deflation channels 151, namely a first inflation and deflation channel 151 and a second inflation and deflation channel 151. Valve seat 149’ may also include third and fourth inflation and deflation channels respectively provided on the side walls of the first inflation and deflation channel and the second inflation and deflation channel. Referring to FIGS. 27and 31, third and fourth inflation and deflation channels may be fine-tuning channels 751. Fine-tuning channels 751 of valve seat 149’ may terminate at fine-tuning openings in fluid communication with respective inflation and deflation channels 151. Still referring to FIGS. 27 and 31, pressure detection interfaces 163 may similarly terminate at pressure detection openings within respective inflation and deflation channels 151.

[0216] Like air pump 100, air pump 100’ may include a main air pump assembly 130. Main air pump assembly 130 may include an air inlet (to avoid ambiguity, hereinafter the first air inlet) in fluid communication with atmosphere through panel 120 and an air outlet (to avoid ambiguity, hereinafter the first air outlet) in selective fluid communication with the inflatable product through turntable 147’ and valve seat 149’.

[0217] Referring to FIG. 26, solenoid valve group 250 may include a valve housing 251 and a valve core 253. Valve core 253 may be disposed in valve housing 251. Valve core 253 may be provided with an air inlet (hereinafter referred to as a second air inlet) and at least one air outlet. The second air inlet may be in fluid communication with supplemental air pump assembly 230 through fine-tuning conduit 256 (see, e.g., FIG. 33), and the air outlet may be in fluid communication with fine-tuning channel 751 through fine-tuning conduit 255 (see, e.g., FIG. 33). In the illustrated embodiment, valve core 253 is provided with two air outlets, namely a second air outlet and a third air outlet. The second air outlet may be in fluid communication with the first fine-tuning channel 751, and the second air outlet may be in fluid communication with the second fine-tuning channel 751. Solenoid valve group 250 may include two valve cores 253 corresponding to the two fine-tuning channels 751. Solenoid valve group 250 may be operable to independently communicate supplemental air pump assembly 230 with first and second fine-tuning channels 751. Solenoid valve group 250 may be operable to simultaneously communicate supplemental air pump assembly 230 with first and second fine-tuning channels 751.

[0218] Referring to FIGS. 26 and 28, valve housing 251 may be coupled to body 110 and include a first valve housing and a second valve housing. First and second valve housings may cooperate to form a chamber that receives valve core 253. In the illustrated embodiment, and valve housing 251 includes an upper valve housing 2511 and a lower valve housing 2512 that cooperate with each other to form a chamber that receives valve core 253.

[0219] Still referring to FIG. 26, supplemental air pump assembly 230 may include a housing 231 and a supplemental air pump 233 disposed in housing 231. Supplemental air pump 233 may include an air inlet (hereinafter referred to as the third air inlet) in fluid communication with atmosphere through panel 120 and an air outlet (hereinafter referred to as the fourth air outlet) in fluid communication with the second air inlet of the solenoid valve group 250 through fine-tuning conduit 256.

[0220] In the illustrated embodiment, housing 231 is fixed within body 110 through fixing plate 235. Housing 231 may include a first housing 2311 and a second housing 2312 that cooperate to form a chamber that houses supplemental air pump 233.

[0221] To facilitate connection of air pump 100’ to connector 187 of the inflatable product, the inflation and deflation channel 151 of valve seat 149’ may be coupled to inflation and deflation pipe 183. Inflation and deflation pipe 183 may in turn be coupled to an intermediate connector 181’. The intermediate connector 181 may then be coupled to the connector 187 of the inflatable product.

[0222] Operation of air pump 100’ will now be described with reference to FIGS. 32-35.

[0223] Referring to FIG. 32, to inflate the inflatable product, the user actuates the corresponding controller of control panel 120, which is operably coupled to control circuit board 171. Control circuit board 171 activates main air pump assembly 130 and switching motor 141 of air passage switch assembly 140’. Switching motor 141 drives turntable 147’ to rotate until inflation and deflation openings 441 of turntable 147’ fluidly communicate the impeller chamber of main air pump assembly 130 with the inflation and deflation channels 151. Once switch 148 detects locator tab 445, switch 148 signals to control circuit board 171 that turntable 147’ is properly oriented relative to valve seat 149’ for inflation operations, and control circuit board 171 deactivates switching motor 141. Airflow generated by main air pump assembly 130 may enter inflation and deflation channels 151 through inflation and deflation openings 441 of turntable 147’. From inflation and deflation channel 151, airflow may pass through inflation and deflation pipe 183 and into the inflatable product through connector 187 to inflate inflatable bladder 20. When the above-described pressure detection assembly detects that the pressure within the inflatable bladder 20 has reached the preset, i.e., desired pressure, control circuit board 171 activates switching motor 71 to drive turntable 147’ to rotate until switch 148 detects locator tab 444 (see FIGS. 30-31). In this position,turntable 147’ fluidly seals the impeller chamber of main air pump assembly 130 from inflation and deflation channels 151. Control circuit board 171 also deactivates main air pump assembly 130.

[0224] Referring to FIG. 33, if the pressure detection assembly detects that the pressure within inflatable bladder 20 has fallen below the preset pressure, supplemental pump assembly 230 and solenoid valve group 250 may cooperate to perform fine-tuning inflation of inflatable bladder 20. Specifically, control circuit board 171 may activate supplemental air pump assembly 230 to generate airflow and activate solenoid valve group 250 to open valve core 253, which opens the second air outlet (or the third air outlet) that is in fluid communication with the first inflation and deflation channel 151 (or the second inflation and deflation channel 151). External air from atmosphere enters supplemental air pump 233 through the third air inlet of supplemental air pump assembly 230, then enters solenoid valve group 250 through the fourth air outlet of supplemental air pump assembly 230 and the second air inlet of the solenoid valve group 250. Airflow may then enter the first inflation and deflation channel 151 (or the second inflation and deflation channel 151) via the second air outlet (or third air outlet) of solenoid valve group 250 and first fine-tuning channel 751 (or second fine-tuning channel 751) of the valve seat 149’, thereby achieving fine-tuned inflation of the corresponding air chamber. When the pressure detection assembly detects that the air chamber has reached the set pressure value, control circuit board 171 deactivates supplemental air pump assembly 230 and solenoid valve group 250 to fluidly seal the inflatable chamber.

[0225] After inflation is completed, the pressure detection assembly continuously monitors air pressure within the inflatable product. If the user wishes to increase the air pressure within the inflatable chamber, the user may actuate the corresponding controller on control panel 120 to initiate the above-described fine-tuning inflation operation. Alternatively, if the pressure within the inflatable chamber falls below the preset level, control circuit board 171 may automatically activate supplemental air pump assembly 230 and solenoid valve group 250 to repeat the above-described fine-tuning inflation operation.

[0226] Now referring to FIG. 34, to incrementally deflate the inflatable chamber, either if the user wishes to incrementally lower the air pressure within the inflatable chamber or if the pressure detection assembly determines that the air pressure within the inflatable chamber 20exceeds the preset pressure, supplemental air pump assembly 230 and solenoid valve group 250 may perform fine-tuning deflation of the inflatable chamber. Control circuit board 171 activates supplemental air pump assembly 230 and solenoid valve group 250. Valve core 253 of solenoid valve group 250 opens the second air outlet (or the third air outlet). Airflow enters the solenoid valve group 250 through first inflation and deflation channel 151 (or the second inflation and deflation channel 151), the first fine-tuning channel 751 (or the second fine-tuning channel 751), and the second air outlet (or the third air outlet), and then passes through the second air inlet of solenoid valve group 250 and the fourth air outlet of the supplemental air pump assembly 230 to enter supplemental air pump assembly 230. From supplemental air pump assembly 230, airflow may be discharged to atmosphere through the third air inlet of the supplemental air pump assembly 230 to deflate the inflatable chamber. When the above-described pressure detection assembly determines that the pressure within the inflatable bladder has reached the preset pressure, control circuit board 171 may deactivate supplemental air pump assembly 230 and solenoid valve group 250. Alternatively, control circuit board 171 may activate solenoid valve group 250, and air within inflatable bladder 20 may vent to atmosphere through solenoid valve group 250 without activation of supplemental air pump assembly 230.

[0227] Referring to FIG. 35, to complete a full deflation of the inflatable bladder 20, the user actuates the corresponding controller of control panel 120, and control circuit board 171 activates main air pump assembly 130 and switching motor 141 of air passage switch assembly 140’ to drive turntable 147’ to rotate until switch 148 detects locator tab 445 of turntable 147’. In this position, inflation and deflation openings 441 of turntable 147’ fluidly communicate the impeller chamber of main air pump group 230 with inflation and deflation channels 151. Air within inflatable bladder 20 may vent to atmosphere through inflation and deflation channels 151, inflation and deflation openings 441 of turntable 147’, and the impeller chamber of main air pump assembly 130, thereby deflating the inflatable bladder.

[0228] Air pump 100’ may include a supplemental air pump assembly 230, a solenoid valve group 250, a main air pump assembly 130, and an air passage switch assembly 140’, each of which may be disposed in body 110. Air passage switch assembly 140’ may fluidly communicate inflatable products with main air pump assembly 130 to inflate or deflate the inflatable product. Supplemental air pump assembly 230 and solenoid valve group 250 maycooperate with air passage switch assembly 140’ to adjust, i.e., fine-tune the pressure within the inflatable product, either by fine-tuning inflation or fine-tuning deflation. When inflation and deflation opening 441 of turntable 147’ of air passage switch assembly 140’ fluidly communicates the impeller chamber of main air pump assembly 230 with inflation and deflation channel 151, main air pump assembly 130 may be activated to inflate or deflate the inflatable product. When turntable 147’ fluidly seals the impeller chamber of main air pump assembly 130 from inflation and deflation channel 151, supplemental air pump assembly 230, and solenoid valve group 250 may be activated so that air may enter body 110 from atmosphere and pass through supplemental air pump assembly 230 and solenoid valve group 250 sequentially. Then, airflow may enter the inflation and deflation channel 151 through fine-tuning channel 751 before entering the inflatable product to fine-tune air pressure within the inflatable product. Alternatively, air within the inflatable product may enter the inflation and deflation channel 151, flow through fine-tuning channel 751 to solenoid valve group 250, and then flow through supplemental air pump assembly 230 before discharging from body 110 to fine-tune the air pressure within the inflatable product. Thus, air pump 100’ may accurately control the internal air pressure of the inflatable product.
