Description

Technical Field

[0001] The present application relates to the field of inflatable products. Background Art

[0002] Inflatable products such as air beds and inflatable sofas are popular among people because of their lightness, ease of packaging and storage. Most inflatable products are formed into a predetermined shape by setting the internal structure. In this way, after inflation, the inflatable product forms a preset shape under the action of the internal air pressure.

[0003] Inflatable products are usually equipped with electric air pumps to facilitate users to inflate the inflation chamber of the inflatable product before using the inflatable product. However, after using the inflatable product, the user needs to exhaust the air in the inflation chamber before folding and storing the inflatable product. In order to achieve the purpose of exhausting the inflatable product, the manufacturer usually configures the electric air pump with a vacuum function to exhaust the air in the inflation chamber to the outside atmosphere. Since the electric motor used for the electric air pump is often unidirectional, the vacuum function of the electric air pump has to be achieved through an additional airway switching device. However, the complex structure of the airway switching device will not only cause a significant increase in the size and weight of the electric air pump, but also significantly increase the cost of the inflatable product.

[0081] To make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0082] In the present application, the directional term "axial" refers to a direction generally along the central axis of a column or a cylinder.

[0083] The inflatable products mentioned in this application may be inflatable furniture such as inflatable mattresses, inflatable pools, inflatable sofas, etc., or inflatable toys such as swimming rings, inflatable castles, etc., or other types of products. Figure 1a to Figure 1e A variety of inflatable products 10 and their internal structures are schematically shown. Each inflatable product 10 includes at least one first wall 11, a second wall 12, and an inflatable chamber 13 defined by the first wall 11 and the second wall 12 for inflation. When the pressure of the gas (e.g., air) in the inflatable chamber 13 reaches a desired value, the inflatable product 10 is in an inflated state and maintains a preset shape; and when the gas in the inflatable chamber 13 is discharged, the inflatable product 10 is in a deflated state, and the volume of the inflatable product 10 is greatly reduced relative to when it is in the inflated state, thereby facilitating the storage of the inflatable product 10.

[0084] A plurality of tensioning members are provided in the inflation chamber 13 of the inflatable product 10, and the tensioning members are connected to the first wall 11 and the second wall 12 by high-frequency welding, hot melting, gluing or other connection methods. After being tensioned, the tensioning members provide a pulling force to the first wall 11 and the second wall 12 to limit the deformation of the inflatable product 10, so that the inflatable product 10 can maintain a preset shape after being inflated.

[0085] Optionally, the plurality of tension members have different structures in different embodiments. For example, each tension member is a sheet-like tension member 21 or a line-like tension member 22 .

[0086] The sheet-like tension member 21 may have a single-layer structure or a composite-layer structure according to actual needs.

[0087] When the sheet-like tension member 21 is a single-layer sheet, it can be made of a polymer material, which can include but is not limited to one or more of polyvinyl chloride (PVC), polyurethane (PU), thermoplastic urethanes (TPU), polyethyleneterephthalate (PET), ethylene-vinyl acetate (EVA) copolymer and nylon. It can be understood that the main body of the single-layer sheet-like tension member 21 can also be made of other materials other than polymer materials in other embodiments, such as a fabric material, wherein the fabric material can be finely woven or formed into a mesh structure. The fabric material can be but is not limited to a natural fiber fabric (for example, but not limited to, cotton fabric, linen fabric, wool fabric, silk fabric) or a synthetic fiber fabric (for example, but not limited to, polyester fiber fabric, polyethylene fiber fabric, polypropylene fiber fabric).

[0088] When the sheet-like tension member 21 is a composite sheet, it is composed of two or more layers of sheets bonded together by gluing, welding or other means, and each layer of the multi-layer sheet can be made of the polymer material or other materials as described above.

[0089] The linear tension member 22 includes one or more wires, which span the distance between the first wall 11 and the second wall 12 of the inflatable product 10 and are optionally parallel or substantially parallel in space, for example, the wires are spaced from each other at equal distances or in a manner that varies according to a certain rule. The material of one or more wires in the linear tension member 22 can be, but is not limited to, natural fibers (for example, but not limited to, cotton fibers, linen fibers, wool fibers, silk fibers) or synthetic fibers (for example, but not limited to, polyester fibers, polyethylene fibers, polypropylene fibers). The linear tension member 22 is usually indirectly connected to the first wall 11 and the second wall 12 via a connector, and the connector can be made of, but is not limited to, a polymer material that facilitates welding of the first wall 11 and the second wall 12.

[0090] Reference Figure 1f For ease of understanding, an embodiment of the present application is described with the inflatable product being an inflatable mattress 18 .

[0091] like Figure 1f and Figure 2As shown, the air mattress 18 includes a first wall 11, a second wall 12, and a side wall 15 connected between the first wall 11 and the second wall 12. The first wall 11, the second wall 12, and the side wall 15 together enclose an air chamber ( Figure 1f 14 is provided on the side wall 15 of the air mattress 18 and communicates with the air chamber, and a mounting seat 40 is installed in the mounting hole 14. The mounting seat 40 is used to accommodate the main pump 30, and the main pump 30 is used to inflate the air mattress 18. For example, the mounting hole 14 is formed by cutting out a portion of the side wall 15 of the air mattress 18. The periphery 401 of the mounting seat 40 and the periphery of the mounting hole 14 are sealed and connected by gluing, welding or other known methods, so that the mounting seat 40 is installed on the air mattress 18.

[0092] like Figure 3 and Figure 4 As shown, the mounting seat 40 includes a first side wall 413, a bottom wall 414 and a panel 402. The first side wall 413 and the bottom wall 414 define a mounting chamber 41. One end of the first side wall 413 is connected to the bottom wall 414, and the other end defines an opening, through which the mounting chamber 41 communicates with the outside. A through hole 415 communicating with the inflation chamber is provided on the bottom wall 414. A hole for mounting the chamber 41 is constructed on the panel 402, and the hole is aligned with the above-mentioned opening to facilitate the installation of the main pump 30 into the mounting chamber 41.

[0093] The mounting base 40 includes a power interface 403, which is used to supply power to the main pump 30. The power interface 403 is optionally a USB interface. When using the inflatable mattress 18, a USB cable can be used to electrically connect the USB interface to a power source (not shown in the figure). Since the USB interface has been widely used, there is no need to replace the power cord with an appropriate plug according to the requirements of different countries or regions, which facilitates the use of the inflatable mattress 18. In addition, in the absence of mains electricity (for example, when using the inflatable mattress 18 outdoors), an appropriate mobile power supply (not shown in the figure) can also be used to power the main pump 30 (or the motor 31 of the main pump 30), which further facilitates the use of the inflatable mattress 18. It can be understood that in other embodiments, the power interface 403 can also be other types of interfaces.

[0094] The mounting base 40 also includes a first electrical connector 410 extending into the mounting chamber 41. The first electrical connector 410 is optionally directly (e.g., via a wire or other similar conductive element) electrically connected to the power interface 403. It is understandable that in other embodiments, the first electrical connector 410 may also be indirectly electrically connected to the power interface 403. For example, a switch or a switch circuit is also connected in series between the first electrical connector 410 and the power interface 403, and the switch or the switch circuit is used to control the on and off of the circuit between the first electrical connector 410 and the power interface 403.

[0095] A main pump 30 is detachably mounted in the mounting chamber 41. The main pump 30 is used to inflate the air mattress 18. A second electrical connector 302 is disposed on the end of the main pump 30 facing the air chamber. Figure 5 As shown, the second electrical connector 302 is optionally a metal block, which is mounted on the main pump 30 and partially exposed. After being set in the installation chamber 41, the main pump 30 blocks the through hole 415 of the installation chamber 41, and the second electrical connector 302 is in electrical contact with the first electrical connector 410, and the first electrical connector 410 and the second electrical connector 302 together form a part of the power supply circuit of the main pump 30. After the main pump 30 is removed from the installation chamber 41, the second electrical connector 302 is separated from the first electrical connector 410, and the through hole 415 is also exposed to the outside atmosphere, so that the outside atmosphere and the inflatable chamber of the inflatable mattress 18 are connected through the through hole 415. Using the detachable first electrical connector 410 and the second electrical connector 302 (rather than the power supply cable) to power the main pump 30 can not only enable the main pump 30 to be powered when it is in the installation chamber 41, but also prevent the power supply cable from being pulled when the main pump 30 is removed from the installation chamber 41. On the one hand, the user can place the removed main pump 30 at any suitable place; on the other hand, the situation in which the power supply cable is pulled and broken can be avoided.

[0096] like Figure 4 As shown, the first electrical connector 410 is optionally arranged near the bottom wall 414. The first electrical connector 410 includes a support plate 416 and a spring 417 arranged on the support plate 416. The spring 417 is made of metal and extends to the inside of the installation chamber 41 to electrically contact the second electrical connector 302 of the main pump 30. In this way, the spring 417 is used as an elastic electrical contact. When the main pump 30 is installed in the installation chamber 41, the spring 417 will be squeezed and deformed by the second electrical connector 302, thereby achieving close contact between the spring 417 and the second electrical connector 302. Moreover, as the main pump 30 is installed inwardly in the installation chamber 41 more tightly, the second electrical connector 302 has a greater squeezing force on the spring 417, so that the second electrical connector 302 and the spring 417 are in closer contact. In addition, the support plate 416 also supports the main pump 30, preventing the main pump 30 from being installed excessively inward in the installation chamber 41. The support plate 416 is a metal plate, and the spring 417 is in electrical contact with the support plate 416, and the support plate 416 is connected to the power interface 403, so that the support plate 416 forms a part of the circuit that supplies power to the main pump 30. Alternatively, in another embodiment, the spring 417 is directly electrically connected to the power interface 403.

[0097] It is understandable that the spring 417 can be replaced by other forms of conductive elements in other embodiments, such as electrical contacts made of metal blocks or elastic metal sheets. It is also understandable that the first electrical connector 410 can also have other structures in other embodiments.

[0098] In this embodiment, the main pump 30 is optionally installed in the installation chamber 41 by means of threads. Figure 4 As shown, a first internal thread 411 is formed on the first side wall 413 of the mounting seat 40. Figure 5 As shown, a first external thread 336 matching the first internal thread 411 is constructed on the side wall 333 (i.e., the second side wall) of the housing 33 of the main pump 30. In this way, the main pump 30 can be installed in the installation chamber 41 in a threaded connection manner, which facilitates the disassembly and assembly of the main pump 30 and can provide better air tightness. It can be understood that the main pump 30 can also be installed in the installation chamber 41 in other ways in other embodiments. For example, a flexible seal can be provided between the main pump 30 and the installation chamber 41, and the flexible seal fixes the main pump 30 in the installation chamber 41 by friction and provides air tightness.

[0099] like Figure 3 and Figure 5 As shown, the main pump 30 includes a housing 33, a motor 31 and an impeller assembly 32. The motor 31 and the impeller assembly 32 are arranged in the housing 33, and the motor 31 is electrically connected to the second electrical connector 302. The housing 33 of the main pump 30 optionally includes a first end wall 331, a second end wall 332 and a side wall 333. The second end wall 332 is opposite to the first end wall 331, and the side wall 333 of the housing 33 of the main pump 30 is connected between the first end wall 331 and the second end wall 332. When the main pump 30 is installed in the installation chamber 41, the first end wall 331 is away from the inflation chamber, and the second end wall 332 is toward the inflation chamber. In this case, the second electrical connector 302 is arranged on the second end wall 332 and is aligned with the first electrical connector 410.

[0100] The above describes the arrangement of the first electrical connector 410 and the second electrical connector 302 by taking the first electrical connector 410 being located near the bottom wall 414 as an example. It can be understood that the first electrical connector 410 can also be arranged at other positions in the installation chamber 41 in other embodiments. For example, the first electrical connector is arranged on the first side wall 413 of the installation chamber 41 or at the opening of the installation chamber 41, and the second electrical connector is arranged accordingly according to the position of the first electrical connector.

[0101] The first end wall 331 of the housing 33, the second end wall 332 of the housing 33, and the side wall 333 of the housing 33 are manufactured and assembled together to form the housing 33, but this is not limiting. In other embodiments, the first end wall 331 of the housing 33, the second end wall 332 of the housing 33, and the side wall 333 of the housing 33 can also be arranged in other ways, for example, one of the first end wall 331 of the housing 33 and the second end wall 332 of the housing 33 is integral with the side wall 333 of the housing 33, and the other is fixed to the side wall 333 of the housing 33 by a threaded fastener, a buckle or other mechanical fixing structure.

[0102] A vent hole 418 is configured on the first side wall 413 of the installation chamber 41. A first air inlet 334 is provided on the first end wall 331, and a first air outlet 335 is configured on the side wall 333 of the housing 33 of the main pump 30. After the main pump 30 is installed in the installation chamber 41, the external environment and the internal space of the housing 33 are communicated through the first air inlet 334. The vent hole 418 is aligned with the first air outlet 335, so that the internal space of the housing 33 and the inflation chamber are communicated through the first air outlet 335 and the vent hole 418.

[0103] Alternatively, if Figure 3 As shown, a first handle 337 is configured on the outer surface of the first end wall 331 (i.e., the surface of the first end wall 331 away from the inner space of the housing 33). In this way, the user can hold the first handle 337 to conveniently disassemble and assemble the main pump 30 by screwing, without the need for other tools, which facilitates the user's operation. In one embodiment, a first screw mark 338 indicating the tightening and loosening directions is provided on the outer surface of the first end wall 331 for the user to refer to when screwing the main pump 30.

[0104] When the air mattress 18 is inflated, the main pump 30 is set in the installation chamber 41, and the second electrical connector 302 is in electrical contact with the first electrical connector 410, so that the second electrical connector 302 is electrically connected to the power interface 403 through the first electrical connector 410. In this way, the main pump 30 can be powered through the power interface 403 without setting a cable connecting the power interface 403 and the main pump 30, which avoids the risk of the user accidentally pulling the cable and causing the main pump 30 to be accidentally pulled outward from the installation chamber 41, so that the main pump 30 can work stably in the mounting seat 40 (or the installation chamber 41). Moreover, after the main pump 30 is installed in the installation chamber 41, the first electrical connector 410 and the second electrical connector 302 are inside the installation chamber 41 and protected by the main pump 30 and the installation chamber 41. This helps to prevent foreign objects from entering between the first electrical connector 410 and the second electrical connector 302, causing unstable power supply to the main pump 30.

[0105] In addition, as the main pump 30 is gradually installed in the installation chamber 41 , the first electrical connector 410 and the second electrical connector 302 are in closer contact with each other, which helps to reduce the contact resistance between the first electrical connector 410 and the second electrical connector 302 .

[0106] When the air mattress 18 is exhausted, the main pump 30 is removed from the installation chamber 41. In this way, the air chamber and the external environment are directly connected through the through hole 415 and the installation chamber 41. Therefore, the gas in the air chamber will be automatically discharged to the external environment through the through hole 415 on the bottom wall 414 of the installation chamber 41 and the installation chamber 41, which helps to improve the exhaust efficiency of the air mattress 18. When exhausting, the user can also squeeze the air mattress 18 (for example, fold the air mattress 18) to allow the air inside the air chamber to be discharged more quickly. It should be understood that the through hole 415 can also be set on the first side wall 413.

[0107] It can be seen that it does not consume electricity to exhaust the air mattress 18, which is particularly beneficial for outdoor use because it is difficult for users to obtain electricity in the wild. It can be understood that in some optional embodiments, the main pump 30 further has a pumping function, that is, the main pump 30 can pump air out of the inflation chamber under the power of electricity, so that the user can exhaust the air mattress 18 without removing the main pump 30 from the air mattress 18.

[0108] After the air mattress 18 is exhausted, the main pump 30 can be placed in the installation chamber 41 again to block the installation chamber 41. This helps prevent foreign matter from the external environment from entering the inflation chamber, helps prevent the main pump 30 from being lost, and can also keep the air mattress 18 in a deflated state for easy storage.

[0109] In addition, since the main pump 30 is detachably installed in the installation chamber 41 of the mounting base 40, multiple disassembly and assembly of the main pump 30 will not easily cause damage to the side wall 15 of the inflatable mattress 18. The mounting base 40 only needs to be maintained or replaced as needed, which helps to reduce the use cost of the inflatable mattress 18.

[0110] The impeller assembly 32 is disposed in the inner space of the housing 33, and the impeller 322 in the impeller assembly 32 is driven by the motor 31 to inflate the air into the air chamber. The motor 31 is electrically connected to the second electrical connector 302, so that the power interface 403 supplies power to the motor 31 through the first electrical connector 410 and the second electrical connector 302. Figure 7As shown, the impeller assembly 32 includes a shell 321 and an impeller 322. The shell 321 of the impeller assembly 32 defines an impeller chamber 320, and the impeller 322 is disposed in the impeller chamber 320. A second air inlet 324 and a second air outlet 325 are configured on the shell 321 of the impeller assembly 32. The internal space of the shell 33 is connected to the impeller chamber 320 through the second air inlet 324, and the first air outlet 335 is connected to the impeller chamber 320 through the second air outlet 325. The impeller 322 is driven to rotate by the motor 31 to drive the air in the external environment to flow into the impeller chamber 320 through the first air inlet 334 and the second air inlet 324, and then flow into the inflation chamber through the second air outlet 325, the first air outlet 335 and the air vent 418, thereby achieving inflation of the air mattress 18.

[0111] The second air outlet 325 is aligned with the first air outlet 335. A sealing member 323 (such as a sealing member 324) surrounding the second air outlet 325 is provided on the shell 321 of the impeller assembly 32. Figure 7 ). After the impeller assembly 32 is assembled into the housing 33, the seal 323 is located between the side wall 333 of the housing 33 and the shell 321 of the impeller assembly 32, and seals the gap between the side wall 333 of the housing 33 and the shell 321 of the impeller assembly 32, which helps to prevent airflow from leaking from the gap, thereby improving the efficiency of inflating the air mattress 18. It can be understood that in other embodiments, the seal can also be set on the side wall 333 of the housing 33; after the impeller assembly 32 is assembled into the housing 33, the seal 323 is located between the side wall 333 of the housing 33 and the shell 321 of the impeller assembly 32, and seals the gap between the side wall 333 of the housing 33 and the shell 321 of the impeller assembly 32.

[0112] like Figure 6 As shown, the shell 321 of the impeller assembly 32 optionally includes a first shell 328 and a second shell 329. The first shell 328 faces the first end wall 331 of the housing 33, and the second shell 329 faces the second end wall 332 of the housing 33. The first shell 328 and the second shell 329 are connected together to form the shell 321 of the impeller assembly 32. The first shell 328 is fixedly connected to the first end wall 331, and the second shell 329 is supported by the second end wall 332. In this way, both ends of the shell 321 of the impeller assembly 32 are constrained by the housing 33, which improves the stability of the impeller assembly 32 in the housing 33.

[0113] The first air inlet 334, the second air inlet 324, the first air outlet 335 and the second air outlet 325 are all arranged on the same side of the motor 31. The outside air is sucked into the impeller assembly 32 through the first air inlet 334 and the second air inlet 324 in turn, and is immediately sent into the inflation chamber of the air mattress 18 through the second air outlet 325 and the first air outlet 335 adjacent to the second air outlet 325 after being pressurized by the impeller 322. Based on this structure, the pressurized air only needs to pass through the extremely short air passage formed by the second air outlet 325 and the first air outlet 335 to enter the inflation chamber, which avoids the loss of pressure of the pressurized air passing through the complex air passage, which helps to improve the efficiency of inflating the air mattress 18.

[0114] Optionally, the main pump 30 further includes a one-way valve 301 (such as Figure 6 The one-way valve 301 is disposed at the first air inlet 334 and opens or closes the first air inlet 334. For example, when the air mattress 18 is inflated, the one-way valve 301 opens the first air inlet 334 so that the gas in the external environment flows into the inflation chamber under the drive of the impeller 322. After the air mattress 18 is inflated, the one-way valve 301 closes the first air inlet 334 to prevent the gas in the inflation chamber from leaking through the first air inlet 334 and causing the air mattress 18 to collapse.

[0115] In one embodiment, the one-way valve 301 is configured as a flexible diaphragm, which is disposed on the inner surface of the first end wall 331 (i.e., the surface of the first end wall 331 facing the inner space of the housing 33) and covers the first air inlet 334. In this way, when the air mattress 18 is inflated, the motor 31 drives the impeller 322 to rotate, so that the air pressure between the second air inlet 324 and the first air inlet 334 is reduced and lower than the external air pressure, and the external air pushes the diaphragm away from the inner surface of the first end wall 331, so that the inflation chamber of the air mattress 18 is in communication with the external fluid through the first air inlet 334. After the air mattress 18 is inflated, the motor 31 stops running, and the internal air pressure of the air mattress 18 is greater than the external air pressure, so that the diaphragm is pressed against the inner surface of the first end wall 331 to close the first air inlet 334. The flexible diaphragm is made of silicone. It can be understood that the diaphragm can also be made of other suitable flexible materials (e.g., rubber) as needed.

[0116] Also like Figure 3As shown, the mounting base 40 further includes a cover 42. When the main pump 30 is installed in the mounting chamber 41 but not in operation, the cover 42 can be installed at the opening position of the mounting chamber 41, wherein the cover 42 seals the main pump 30 in the mounting chamber 41. When the seal between the main pump 30 and the mounting chamber 41 fails (for example, the main pump 30 becomes loose, or the optional one-way valve 301 described above fails), the cover 42 can prevent the air mattress 18 from leaking, thereby further enhancing the air tightness of the air mattress 18. When the main pump 30 is used to inflate the air mattress 18, the cover 42 is removed from the mounting chamber 41 to expose the main pump 30.

[0117] In an optional embodiment, a drawstring (not shown) may be used to connect the cover 42 to the panel 402 of the mounting base 40 or the main pump 30 to prevent the cover 42 from being lost.

[0118] Alternatively, if Figure 3 and Figure 4 As shown, a second external thread 420 is configured on the cover 42, and a second internal thread 412 matching the second external thread 420 is configured on the installation chamber 41. The cover 42 is installed in the installation chamber 41 through the second external thread 420 and the second internal thread 412. Along the axial direction of the installation chamber 41, the second internal thread 412 is located on the outside of the first internal thread 411, so that the cover 42 can be installed on the outside of the main pump 30. In one embodiment, a second handle 427 is configured on the outer surface of the cover 42. In this way, the user can hold the second handle 427 to conveniently disassemble and assemble the cover 42 in a screwing manner without the need for other tools. As also shown Figure 3 As shown, a second screw mark 428 indicating the tightening and loosening directions is provided on the outer surface of the cover 42 for reference by the user when screwing the cover 42 .

[0119] Alternatively, if Figure 3As shown, the air mattress 18 further includes a control switch 310 for controlling the operating state of the motor 31. The control switch 310 is used to detect whether the cover 42 is installed on the mounting seat 40. When the cover 42 is not installed on the mounting seat 40, the main pump 30 is in communication with the outside air, the motor 31 is in a working state, and the main pump 30 inflates the air mattress 18; and when the cover 42 is installed on the mounting seat 40, the main pump 30 is enclosed in the mounting seat 40, the motor 31 is in a stopped state, and the main pump 30 stops inflating the air mattress 18. For example, when the user removes the cover 42, the power supply circuit of the motor 31 is connected, and the main pump 30 starts to work; when the air mattress 18 is inflated, the user covers the cover 42, the power supply circuit of the motor 31 is cut off, and the main pump 30 stops working. In this way, on the one hand, the user can very conveniently stop inflating the air mattress 18 by simply installing the cover 42 without performing additional operations; on the other hand, the cover 42 can also ensure the airtightness of the air mattress 18. At the same time, the main pump 30 stops operating in response to the cover 42 being mounted on the mounting base 40, and the motor 31 is prevented from continuing to operate and burning out after the cover 42 is closed.

[0120] The control switch 310 may be, but is not limited to, a push switch disposed on the housing 33. When the push switch 310 is pressed, the motor 31 is configured to stop working; when the push switch 310 is not pressed, the motor 31 is configured to operate. Fig.11 is a non-limiting control circuit diagram, in which the push switch 310 is connected in series to the power supply circuit of the motor 31, and the push switch 310 is turned on when not pressed and turned off when pressed. When the push switch 310 is not pressed, the power supply circuit 311 of the motor 31 is closed, and the motor 31 is in a working state. When the push switch 310 is pressed, the power supply circuit 311 of the motor 31 is disconnected, and the motor 31 does not work.

[0121] like Figure 8 As shown, a pressing assembly 43 is provided on the cover 42. The pressing assembly 43 faces the main pump 30 and is used to press the pressing switch 310 when the cover 42 is installed on the mounting seat 40. The pressing assembly 43 protrudes toward the pressing switch 310 and is aligned with the pressing switch 310. After the inflatable mattress 18 is inflated, when the cover 42 is installed on the mounting seat 40, the pressing assembly 43 presses the pressing switch 310 to disconnect the power supply circuit 311 of the motor 31, and the motor 31 stops working. In other words, even if the motor 31 is in a working state, once the cover 42 is approached or installed in the mounting chamber 41, the motor 31 will stop working immediately.

[0122] The pressing assembly 43 may optionally have a retractable structure and be configured to extend itself when not compressed. This retractable structure allows the pressing switch 310 to be pressed when the cover 42 is close to the main pump 30 (without being fully mounted on the mounting base 40), thereby completely preventing the main pump 30 from being damaged when operating under the condition of air intake obstruction.

[0123] For example, the pressing assembly 43 includes a fixing member 431 and a movable member 439. The fixing member 431 is fixedly disposed on the cover 42. For example, the fixing member 431 is generally tubular, one end of which is fixed to the cover 42, and the fixing member 431 generally extends toward the main pump 30 along a direction perpendicular to the surface of the cover 42. The movable member 439 is accommodated in the fixing member 431 and is connected to the fixing member 431 so as to be axially movable relative to the fixing member 431. When the cover 42 is mounted on the mounting seat 40, the movable member 439 abuts against the pressing switch 310.

[0124] refer to Fig. 9 , the movable member 439 includes a pressing rod 432. The pressing assembly 43 also includes a first elastic member (e.g., a compressed coil spring) 434, and the two ends of the first elastic member 434 abut against the pressing rod 432 and the cover 42, respectively. In this way, the first elastic member 434 pushes the pressing rod 432 to extend toward the pressing switch 310 and keeps pressing the pressing switch 310. The movable member 439 also includes a sleeve 433. The sleeve 433 is sleeved in the fixing member 431 and can move axially. The pressing assembly 43 may also optionally include a second elastic member (e.g., a compressed coil spring) 435. One end of the second elastic member 435 is accommodated in the fixing member 431 and abuts against the sleeve 433, and the other end abuts against the cover 42. In this way, the second elastic member 435 pushes the sleeve 433 to extend from the fixing member 431 toward the pressing switch 310, and allows the sleeve 433 to be partially or completely accommodated in the fixing member 431 when subjected to external pressure. The pressing rod 432 is at least partially located in the sleeve 433, and the end of the pressing rod 432 away from the cover 42 is configured with a pressing protrusion 436 protruding toward the pressing switch 310. Overall, the pressing assembly 43 forms a multi-stage telescopic structure.

[0125] Specifically, when the cover 42 is not installed in the installation chamber 41, the second elastic member 435 pushes the sleeve 433 to extend from the fixing member 431, and the first elastic member 434 pushes the pressing rod 432 to extend from the sleeve 433. A flange 437 extending radially inward is configured at the end of the fixing member 431, and a step 438 matching the flange 437 of the fixing member is configured on the circumferential outer surface of the sleeve 433. The sleeve 433 extends from the fixing member 431 until the step 438 of the fixing member abuts against the flange 437 of the sleeve, and then it cannot extend further. A flange 447 extending radially inward is configured at the end of the sleeve 433, and a step 448 matching the flange 447 of the sleeve is configured on the circumferential outer surface of the pressing rod 432. The pressing rod 432 extends from the sleeve 433 until the step 448 of the pressing rod abuts against the flange 447 of the sleeve, and then it cannot extend further. In this way, the pressing protrusion 436 is separated from the cover 42 by a predetermined distance.

[0126] like Fig.10 As shown, when the cover 42 is installed, the pressing rod 432 (or the pressing protrusion 436) contacts the pressing switch 310, and the pressing rod 432 is retracted into the fixing member 431 by the thrust of the pressing switch 310. On the other hand, after the pressing protrusion 436 contacts the pressing switch 310, the first elastic member 434 will push the pressing protrusion 436 to keep pressing against the pressing switch 310 during the process of continuing to install the cover 42. In response to the pressing switch 310 being pressed, the motor 31 stops working. In other words, as long as the first elastic member 434 has sufficient rigidity, the motor 31 can stop working without installing the cover 42 in place, which prevents the main pump 30 from continuing to work under the condition of blocked air intake and overheating or even damage.

[0127] In addition, according to Fig. 9 In the illustrated pressing assembly 43, after the first elastic member 434 and the second elastic member 435 are extended, the distance between the pressing protrusion 436 on the pressing rod 432 and the cover 42 is substantially the sum of the lengths of the fixing member 431, the sleeve 433 and the pressing rod 432. When the cover 42 is installed, this multi-stage telescopic structure is conducive to allowing the pressing protrusion 436 to press the pressing switch 310 as early as possible in a limited space.

[0128] It is understandable that the second elastic member 435 may be omitted in some alternative embodiments, and the sleeve 433 is driven by the pressing rod 432 to extend out of the fixing member 431 .

[0129] like Fig. 9 and Fig.10 As shown, the cover 42 may be optionally provided with a retaining rod 429 extending toward the push switch 310. The push rod 432 is provided with a recessed portion 430 matching the retaining rod 429. When the cover 42 is not installed in the installation chamber 41, the push rod 432 may be axially separated from the retaining rod 429 (eg, Fig. 9 As shown in FIG. 4 ). When the cover 42 is installed in the installation chamber 41, the retaining rod 429 is aligned with the push switch 310. As the cover 42 is gradually installed in the installation chamber 41, the sleeve 433 and the push rod 432 move toward the cover 42. The recessed portion 430 of the push rod 432 gradually fits with the retaining rod 429, so that the sleeve 433 and the push rod 432 are gradually sleeved on the retaining rod 429 (as shown in FIG. 4 ). Fig.10 In this way, the retaining rod 429 prevents the pressing rod 432 from shaking in the radial direction and keeps the pressing rod 432 aligned with the pressing switch 310 in the axial direction, thereby ensuring that the pressing protrusion 436 on the pressing rod 432 stably presses the pressing switch 310 to prevent the main pump 30 from accidentally starting.

[0130] It is understandable that in other embodiments, the pressing assembly 43 may also be configured as a protrusion with a fixed length (i.e., without a telescopic structure), as long as the pressing assembly 43 is configured to just press the pressing switch 310 after the cover 42 is mounted on the mounting base 40. The pressing switch 310 may optionally be a micro switch.

[0131] It can also be understood that the above is only a specific implementation of the control switch 310, and other known implementations of the control switch 310 can also be used to control the motor 31. In an alternative embodiment, a logic circuit and a corresponding switch / sensor can be set to control the operating state of the motor 31; the on-off of the power supply circuit of the motor 31 can be optionally controlled by a relay. For example, a push switch similar to the above can be set, the difference is that the push switch is closed and turned on when pressed, and is disconnected when not pressed, and the logic circuit detects the on-off of the push switch and generates a corresponding control signal to control the on-off of the power supply circuit of the motor 31. For another example, a Hall element can be set on the main pump 30, and a permanent magnet can be set on the cover 42 at a position corresponding to the Hall element; due to the Hall effect, when the permanent magnet approaches and moves away from the Hall element, the Hall element outputs different electrical signals, and the logic circuit detects the electrical signal output by the Hall element and generates a corresponding control signal to control the on-off of the power supply circuit of the motor 31.

[0132] Optionally, Figure 4As shown, the mounting seat 40 further includes a receiving groove 44 adjacent to the first side wall 413 of the mounting chamber 41. An air replenishing pump 441 and a pressure regulating device 442 are arranged in the receiving groove 44. After the air pressure of the air mattress 18 drops, the air replenishing pump 441 can be used to replenish the air in the air mattress 18. The pressure regulating device 442 is used to monitor the air pressure value in the air mattress 18. When the air mattress 18 is inflated, if the pressure regulating device 442 detects that the air pressure value in the air mattress 18 reaches a set threshold, a stop signal of the main pump 30 is sent to stop inflating the air mattress 18. After the air mattress 18 is inflated, if the pressure regulating device 442 detects that the air pressure value in the air mattress 18 is lower than the set threshold, a running signal of the air replenishing pump 441 is sent to replenish the air in the air mattress 18; and if the pressure regulating device 442 detects that the air pressure value in the air mattress 18 reaches the set threshold, a stop signal of the air replenishing pump 441 is sent to stop replenishing the air in the air mattress 18. The air supply pump 441 and the pressure regulating device 442 are well known to those skilled in the art and will not be described in detail here.

[0133] Optionally, Figure 4 As shown, the mounting base 40 further includes a receiving cavity 45. The receiving cavity 45 is outside the receiving groove 44 and the bottom plate 452 of the receiving cavity 45 covers the receiving groove 44. The receiving cavity 45 is also adjacent to the first side wall 413 of the mounting chamber 41. Figure 4 As shown, from the outside of the mounting base 40, the storage cavity 45 and the receiving slot 44 form a whole. The storage cavity 45 can be used to store cables (not shown in the figure) or other items that are compatible with the power interface 403. Optionally, the storage cavity 45 is also equipped with a flip cover 451, which covers the storage cavity 45 as needed to prevent the items (e.g., cables) stored in the storage cavity 45 from being lost.

[0134] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
