Detailed Implementation

[0071] The following detailed embodiments are provided to help the reader gain a comprehensive understanding of the methods, apparatus, and / or systems described herein. However, various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will be apparent after understanding the disclosure of this application. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein; changes that will be apparent after understanding the disclosure of this application are possible, except for operations that must occur in a specific order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0072] The features described herein may be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein have been provided merely to illustrate some of the many feasible ways of implementing the methods, apparatus, and / or systems described herein that will be apparent upon understanding the disclosure of this application.

[0073] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements in between. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly on" another element, or "directly covering" another element, there may be no other elements in between.

[0074] As used herein, the term “and / or” includes any one of the relevant items listed and any combination of any two or more items.

[0075] Although terms such as “first,” “second,” and “third” may be used herein to describe individual components, assemblies, regions, layers, or parts, these components, assemblies, regions, layers, or parts are not limited by these terms. Rather, these terms are used only to distinguish one component, assembly, region, layer, or part from another. Therefore, without departing from the teachings of the examples described herein, the first component, assembly, region, layer, or part referred to as the second component, assembly, region, layer, or part may also be referred to as the second component, assembly, region, layer, or part.

[0076] For ease of description, spatial relation terms such as “above,” “upper,” “below,” and “lower” are used herein to describe the relationship between one element and another, as shown in the accompanying drawings. Such spatial relation terms are intended to include not only the orientation depicted in the drawings but also different orientations of the device during use or operation. For example, if the device in the drawings is flipped, an element described as being “above” or “upper” relative to another element will subsequently be “below” or “lower” relative to that other element. Therefore, the term “above” includes both “above” and “below” orientations depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relation terms used herein will be interpreted accordingly.

[0077] The terminology used herein is for the purpose of describing various examples only and is not intended to limit this disclosure. Unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. The terms “comprising,” “including,” and “having” enumerate the stated features, quantities, operations, components, elements, and / or combinations thereof, but do not exclude the presence or addition of one or more other features, quantities, operations, components, elements, and / or combinations thereof.

[0078] Variations in the shapes shown in the accompanying drawings may occur due to manufacturing techniques and / or tolerances. Therefore, the examples described herein are not limited to the specific shapes shown in the accompanying drawings, but include changes in shape that may occur during manufacturing.

[0079] The features of the examples described herein can be combined in various ways that will be apparent upon understanding the disclosure of this application. Furthermore, although the examples described herein have a wide variety of constructions, other constructions are possible, as will be apparent upon understanding the disclosure of this application.

[0080] As a common means of transportation, cars occupy an important place in people's lives. As cars are driven, the air volume in the tires will decrease, which reduces the stability and safety of the car. Therefore, it is necessary to use a car inflation device to inflate the tires.

[0081] A paddleboard is a type of water sports equipment. Compared to rigid paddleboards, inflatable paddleboards have the advantages of being foldable when deflated, making them convenient for transportation and storage. They can be inflated using a paddleboard inflation device, and are therefore becoming increasingly popular among water sports enthusiasts.

[0082] Existing car tire inflators, designed to address issues like cylinder sealing and accurate pressure detection, often suffer from structural inefficiencies. Furthermore, existing car tire inflators, car jump starters, and paddleboard inflators are separate products. Using a car tire inflator to inflate a paddleboard results in excessively long inflation times due to the low airflow, potentially causing the inflator to overheat and break down. Conversely, the low air pressure generated by a paddleboard inflator is insufficient for inflating car tires. Therefore, existing tire inflators are not only structurally flawed but also fail to meet diverse inflation needs.

[0083] This application provides an emergency device to address the problem that existing car inflation devices and car emergency jump starters are separate products with unreasonable structures. It also solves the problem that existing inflation devices capable of generating high-pressure airflow cannot provide large-flow gas, or that existing inflation devices capable of generating large-flow gas cannot provide high-pressure airflow, while addressing the problem of unreasonable structure.

[0084] The emergency equipment provided in this application will be described in detail below with reference to Figures 1 to 19.

[0085] As shown in Figures 5, 8, and 10, this application provides an emergency device comprising a first housing 7, an air pump 6, an internal power supply 3, an output terminal 1, two first cables 4, two second cables 5, and a first circuit board 2. The first housing 7 internally houses the air pump 6, the internal power supply 3, the output terminal 1, the two first cables 4, the two second cables 5, and the first circuit board 2. The internal power supply 3 is electrically connected to the output terminal 1 via the first cables 4, which output a first current for starting the car. When the car battery is low on power, this first current is used to start the car engine. The internal power supply 3 is electrically connected to the first circuit board 2, which is electrically connected to the air pump 6 via the second cables 5, which output a second current, greater than the first current. For example, the internal power supply 3 can be a lithium battery or a supercapacitor, etc.; one end of a first cable 4 is electrically connected to the positive terminal (not shown in the figure) of the internal power supply 3, and the other end of the first cable 4 is electrically connected to the positive terminal of the output terminal 1. In the actual product, the first cable 4 is red; one end of another first cable 4 is electrically connected to the negative terminal (not shown in the figure) of the internal power supply 3, and the other end of the other first cable 4 is electrically connected to the negative terminal of the output terminal 1. In the actual product, the other first cable 4 is black; a second cable 5 is electrically connected to the positive terminal of the air pump 6. In the original design, the second cable 5 is red; another second cable 5 is electrically connected to the negative terminal of the air pump 6. In the actual product, this other second cable 5 is black. The first cable 4 is red and black to prevent the positive terminal of the internal power supply 3 from being electrically connected to the negative terminal of the output terminal 1 during installation. The second cable 5 is red and black to prevent the positive terminal of the first circuit board 2 from being electrically connected to the positive terminal of the air pump 6 during installation. The diameter of the first cable 4 is larger than the diameter of the second cable 5. This choice of different diameters is to effectively reduce costs and enhance service life while meeting product functionality.

[0086] In this embodiment, the internal power supply 3 can output a first current to the car, and the air pump 6 can inflate the device to be inflated. Based on a reasonable structural layout, the air inflator and the car emergency starter power supply are integrated into one, so as to not only meet the car's starting needs, but also its inflation needs.

[0087] It should be understood that this emergency device can also be understood as a car emergency jump starter with an inflation function or an emergency jump starter with an inflation function. It integrates an air pump 6 and an internal power supply 3. Therefore, this emergency device has both the function of outputting current to start the car through the output terminal and the inflation function from the air pump 6.

[0088] More specifically, as shown in Figures 1 to 10 and 14, in this embodiment, the air pump 6 has a first power unit 30, a detection component 20, and a first one-way valve 50. The first power unit 30 includes a first drive component 31 and a first inflation component 311. The first inflation component 311 includes a first transmission component 3111, a first cylinder component 32, and a connecting pipe 10. The first transmission component 3111 includes a transmission wheel and an eccentric wheel. One end of the first transmission component 3111 is connected to the first drive component 31, and the other end of the first transmission component 3111 is connected to one end of the first cylinder component 32. The connecting pipe 10 has a first air inlet 110 and a first air outlet 120. The other end of the first cylinder component 32 is connected to the first air inlet 110, which has a first air inlet 111, and the first air outlet 120 has a first air outlet 121. For example, the central axis of the first air inlet 111 is parallel or substantially parallel to the central axis of the first air outlet 121, or the central axis of the first air inlet 111 is perpendicular or substantially perpendicular to the central axis of the first air outlet 121, or the central axis of the first air inlet 111 and the central axis of the first air outlet 121 are on the same straight line or substantially on the same straight line. The first cylinder assembly 32 has a cylinder outlet 35 that is sealed to the first air inlet 110. The cylinder outlet 35 has a cylinder outlet 352. The cylinder outlet 35 and the connecting pipe 10 form a first receiving space 112. A first one-way valve 50 is disposed in the first receiving space 112 to allow the first power device 30 to provide a first airflow from the cylinder outlet 352 to the first air outlet 120. The first inflation assembly 311 has a first air passage 1001 and a second air passage 1002. The first air passage 1001 and the second air passage 1002 are connected and a connecting port 1003 is formed at the connection. The first inflation assembly 311 has a detection unit 13 near the connection between the first cylinder assembly 32 and the connecting pipe 10. The detection unit 13 has a second air passage 1002. The detection assembly 20 is sealed to the detection unit 13 and is used to detect the air pressure information of the second air passage 1002. The first drive assembly 31 provides power to the first inflation assembly 311, enabling the first inflation assembly 311 to provide a first airflow to the first air outlet 120 through the first air passage 1001. The detection assembly 20 can detect the air pressure information to meet the different air pressure requirements during inflation.

[0089] The first air passage 1001 can guide the first airflow from the cylinder outlet 352 to the first air outlet 120. The second air passage 1002 can guide the airflow in the first air passage 1001 to the detection component 20. When the air pump 6 is connected to the device to be inflated and stops providing the first airflow, the detection component 20 can detect the air pressure information of the device to be inflated in the second air passage 1002.

[0090] In this embodiment, the detection unit 13 is located near the connection between the first cylinder assembly 32 and the connecting pipe 10. That is, the detection unit 13 can be located on the cylinder 34 or on the connecting pipe 10.

[0091] In the first alternative, as shown in Figures 7, 8, and 9, the first cylinder assembly 32 includes a connecting rod 36, a piston 33, and a cylinder 34. One end of the connecting rod 36 is connected to the first transmission assembly 3111, and the other end of the connecting rod 36 is connected to the piston 33. The cylinder 34 includes a first cylinder 341 and a second cylinder 342. The diameter of the first cylinder 341 is larger than the diameter of the second cylinder 342. The piston 33 is disposed inside the first cylinder 341, and the detection unit 13 is disposed on the second cylinder 342. The detection assembly 20 detects air pressure information through the detection unit 13 on the second cylinder 342.

[0092] Furthermore, as shown in Figures 7 and 8, the emergency equipment also includes a first protective element 8, which is disposed between the connecting pipe 10 and the first housing 7 to protect the connecting pipe 10. The first protective element 8 has a second receiving space 81 and a fourth through hole (also referred to as a protective element through hole) 82. The second receiving space 81 is used to receive the connecting pipe 10, that is, at least part of the connecting pipe 10 is disposed in the second receiving space 81, and the external air pipe 90 extends into the fourth through hole 82 to connect with the connecting pipe 10.

[0093] In the second optional installation method, as shown in Figures 1, 3 and 6, the first cylinder assembly 32 includes a connecting rod 36, a piston 33 and a cylinder 34. One end of the connecting rod 36 is connected to the first transmission assembly 3111, and the other end of the connecting rod 36 is connected to the piston 33. The piston 33 is disposed inside the cylinder 34. The detection part 13 is disposed on the connecting pipe 10, and the detection assembly 20 detects air pressure information through the detection part 13 on the connecting pipe 10.

[0094] In this embodiment, there are at least two ways to install the detection component 20 on the detection unit 13.

[0095] In a first alternative, as shown in Figures 7 and 9, the air pump 6 includes a first fixing member 100, and the circumferential sidewall of the detection part 13 has a first groove 301 for receiving part of the detection component 20. The first fixing member 100 is connected to the detection part 13 to limit the displacement of the detection component 20 on the detection part 13. For example, the detection component 20 includes a second circuit board 21 and a pressure sensor 22. The pressure sensor 22 is connected to the second circuit board 21. The detection part 13 has a first groove 301, a fourth groove (also referred to as the first detection groove) 3010, and a second air passage 1002. The first groove 301 is disposed on the circumferential sidewall of the detection part 13. During installation, part of the second circuit board 21 enters the first groove 301 from the outside of the detection part 13 and then moves to a preset position. A sealing ring is disposed in the fourth groove 3010. The second circuit board 21 is electrically connected to the first circuit board 21 from the outside of the detection part 13. A first fixing member 100 is disposed on the second circuit board 21 and is fixedly connected to the detection part 13 by screws. The pressure sensor 22 is disposed on the side of the second circuit board 21 facing away from the first fixing member 100 and is located in the second air passage 1002, thus realizing pressure detection.

[0096] Specifically, the second circuit board 21 is formed into a plate-like structure, the air pressure sensor 22 is mounted on the second circuit board 21 and protrudes from the surface of the second circuit board 21, the fourth groove 3010 is used to accommodate at least part of the second circuit board 21, that is, the groove wall of the fourth groove 3010 covers at least part of the circumferential sidewall of the second circuit board 21, and the first fixing member 100 is provided with a through hole for screws to pass through, so as to fix the first fixing member 100 and the detection part 13, thereby achieving a sealed connection between the second circuit board 21 and the detection part 13.

[0097] In the second alternative, as shown in Figures 4, 14, and 18, the air pump 6 includes a first hose 400 and a first air guide 600. The first hose 400 is a flexible tubular structure. One end of the first hose 400 is sealed to the detection unit 13, and the other end of the first hose 400 is sealed to the first air guide 600, thus guiding the airflow and meeting the installation space requirements. The first air guide 600 can be sealed to the first hose 400 by interference fit or by fastening with fasteners. The first air guide 600 is formed into a cylindrical structure. One end of the first air guide 600 is connected to the first hose 400, and the other end of the first air guide 600 is used to install the detection component 20.

[0098] Specifically, as shown in Figures 4 and 18, the first air guide 600 has a second groove 302 for accommodating part of the detection component 20, thus fixing the detection component 20 to the first air guide 600. The second groove 302 is connected to the first flexible hose 400, allowing airflow to the detection component 20. The first air guide 600 and the detection component 20 are sealed together, for example, by sandwiching a sealing element between the first air guide 600 and the detection component 20. More specifically, the detection component 20 includes a second circuit board 21 and a pressure sensor 22. The pressure sensor 22 on the second circuit board 21 is embedded in the second groove 302, which surrounds the circumferential sidewall of the pressure sensor 22. In an optional embodiment, the second circuit board 21 has a through hole for screws to pass through, thereby connecting the second circuit board 21 to the first air guide 600 and fixing the detection component 20.

[0099] In this embodiment, as shown in Figures 3, 4, and 6, the connecting pipe 10 includes a first air pipe 101, which is formed into a cylindrical hole structure and has a first air passage 1001 for outputting a first airflow. The first air pipe 101 includes a first sub-first air pipe 1011 and a second sub-first air pipe 1012. The first sub-first air pipe 1011 includes a first air inlet 111, which includes a first sub-first air inlet 1111 and a second sub-first air inlet 1112. The cross-sectional area of ​​the first sub-first air inlet 1111 is larger than the cross-sectional area of ​​the second sub-first air inlet 1112. The first sub-first air pipe 1011 and the cylinder outlet 35 form a first receiving space 112. The inner wall of the first sub-first air pipe 1011 is provided with at least one first protrusion 113, which is used to prevent the first one-way valve 50 from blocking the second sub-first air inlet 1112. For example, the first protrusion 113 is disposed on the inner wall of the side where the first sub-first air pipe 1011 and the second sub-first air pipe 1012 are connected, or the first protrusion 113 is disposed on the inner wall of the first sub-first air pipe 1011 that is perpendicular or substantially perpendicular to the central axis of the cylinder outlet 352.

[0100] It should be noted that, in this embodiment, the cross-sectional area is expressed as the area of ​​the cross section perpendicular to the direction of airflow.

[0101] Furthermore, in this embodiment, as shown in Figures 4 and 6, the first one-way valve 50 has a base 51 and a second protrusion 52. At least one second protrusion 52 is provided on the edge of the base 51 facing the end of the connecting pipe 10. The second protrusion 52 is used to prevent the first one-way valve 50 from blocking the first air inlet 110 or the second sub-first air inlet 1112. The cross-sectional area of ​​the base 51 is larger than the cross-sectional area of ​​the cylinder outlet 352, so as to play the role of unidirectional airflow.

[0102] In this embodiment, as shown in Figures 4 and 6, the air pump 6 includes an elastic element 60, which may be a spring. The elastic element 60 and the first one-way valve 50 are disposed in the first receiving space 112. The first one-way valve 50 is disposed between the elastic element 60 and the cylinder outlet 352, and is used to allow the first power device 30 to provide a first airflow from the cylinder outlet 352 to the first air outlet 120.

[0103] Furthermore, in this embodiment, the elastic member 60 has a first through hole 61, and the elastic member 60 is in a compressed state within the first accommodating space 112. When the air pump 6 is not in operation, the elastic member 60 provides force to the first one-way valve 50, causing the first one-way valve 50 to block the cylinder outlet 352.

[0104] Furthermore, the first one-way valve 50 has a base 51, a third protrusion 53, and a fourth protrusion 54. The cross-sectional area of ​​the base 51 is larger than the cross-sectional area of ​​the cylinder outlet 352 to facilitate one-way airflow. The third protrusion 53 extends into the first through hole 61 to limit the elastic element 60. The fourth protrusion 54 extends into the cylinder outlet 352. For example, the base 51 and the third protrusion 53 are cylinders, and the fourth protrusion 54 is a cone. The cross-sectional area of ​​the third protrusion 53 is smaller than the cross-sectional area of ​​the base 51. The central axis of the third protrusion 53 is on the same straight line or substantially on the same straight line as the central axis of the base 51.

[0105] Specifically, the cylinder outlet 352 includes a first sub-cylinder outlet 3521 and a second sub-cylinder outlet 3522. The cylinder outlet 352 has a stepped hole structure. The cross-sectional area of ​​the first sub-cylinder outlet 3521 is larger than that of the second sub-cylinder outlet 3522. More specifically, the fourth protrusion 54, as described above, extends into the first sub-cylinder outlet 3521 or the second sub-cylinder outlet 3522, thereby achieving positioning assembly and sealing.

[0106] Furthermore, in this embodiment, as shown in Figures 10 and 11, the air pump 6 includes a second hose 500 and a second air guide 700. The second hose 500 is a flexible tubular structure. One end of the second hose 500 is sealed to the first air outlet 120, and the other end of the second hose 500 is sealed to one end of the second air guide 700. The other end of the second air guide 700 is used to connect to the device to be inflated, thereby realizing the transmission of airflow in the second hose 500 to the device to be inflated via the second air guide 700.

[0107] In this embodiment, the device to be inflated can be an inflatable paddleboard or a car tire.

[0108] Furthermore, in this embodiment, as shown in Figures 10 and 11, the second air guide 700 has a third air inlet 701 and a third air outlet 702, which are used to guide the airflow delivered from the second hose 500. The third air inlet 701 is sealed to the second hose 500. The sealing connection can be an interference fit or by adding fasteners to the second hose 500. The third air outlet 702 is used to connect to the device to be inflated. The third air inlet 701 and the third air outlet 702 are not coaxial. The second air guide 700 can be an adapter.

[0109] Furthermore, as shown in Figure 11, due to the misalignment of the third air inlet 701 and the third air outlet 702, the second air guide 700 manufactured by the casting process can be provided with a connecting hole 703 for demolding. However, this connecting hole 703 can cause air leakage when the airflow enters the second air guide 700 through the third air inlet 701. To solve this problem, in this embodiment, the air pump 6 also includes a second fixing member 200. The second air guide 700 has a connecting hole 703 that communicates with the third air inlet 701 and the third air outlet 702 respectively. The second fixing member 200 is used to seal the connecting hole 703, so that all the airflow entering the second air guide 700 through the third air inlet 701 can flow out through the third air outlet 702, thereby achieving the effective airflow guidance function of the second air guide 700. In this embodiment, the second fixing member 200 can be a screw or a rubber plug, as long as it can block the connecting hole 703 to ensure that only the third air inlet 701 and the third air outlet 702 are connected in the second air guide member 700.

[0110] In this embodiment, as shown in Figures 3, 4 and 6, a third groove 114 is provided on the side of the first air inlet 110 facing the cylinder outlet 35, and a fifth protrusion 353 is provided on the cylinder outlet 35. The fifth protrusion 353 has a cylinder outlet 352, and the third groove 114 is used to receive part or all of the fifth protrusion 353.

[0111] Furthermore, in this embodiment, as shown in Figures 3 and 4, a first sealing element 115 is provided between the third groove 114 and the fifth protrusion 353, and the first sealing element 115 may be a sealing ring.

[0112] In a preferred embodiment, as shown in Figures 6, 12, 13, 15, and 16, the first cylinder assembly 32 includes a connecting rod 36, a cylinder seal 37, a piston 33, and a cylinder 34. The cylinder seal 37 provides a sealing function when the air pump 6 generates the first airflow and satisfies the air supply requirements of the first cylinder assembly 32. The piston 33 is disposed within the cylinder 34 and has a first side portion 331 and a second side portion 332. The first side portion 331 is connected to the connecting rod 36, and the second side portion 332 is connected to the first side portion 332. The portions 331 are arranged opposite each other along the axial direction of the piston 33. The first side portion 331 has a first surface 3311 on the side facing the second side portion 332, and the second side portion 332 has a second surface 3321 on the side facing the first side portion 331. The first surface 3311 and the second surface 3321 form a piston receiving space 3300 for receiving at least a portion of the cylinder seal 37, such that the cylinder seal 37 is fitted between the first side portion 331 and the second side portion 332. For example, the maximum distance from the outer edge of the second side portion 332 projected onto the first surface 3311 to the center of the first surface 3311 is less than the maximum distance from the outer edge of the first surface 3311 to the center of the first surface 3311; another example is that the cross-sectional area of ​​the second side portion 332 is less than or equal to the cross-sectional area of ​​the first side portion 331.

[0113] Specifically, in this embodiment, the outer periphery of the second side portion 332 has at least one side groove 333, the opening of which faces the side wall of the cylinder 34. The side wall of the cylinder 34 is parallel or substantially parallel to the direction of movement of the piston 33, providing operating space for the installation of the cylinder seal 37, so that the cylinder seal 37 can be installed between the first side portion 331 and the second side portion 332, thereby improving work efficiency.

[0114] In a preferred embodiment, the second side portion 332 has four identical or substantially identical side grooves 333, which are evenly or substantially uniformly distributed. Two side grooves 333 form a group and are arranged opposite to each other along the radial direction of the piston 33, such that the projection of the second side portion 332 onto the first side portion 331 forms a cross-shaped structure, or a substantially cross-shaped structure, to ensure that the four side grooves 333 are evenly distributed. In this embodiment, the four side grooves 333 are equally spaced around the circumferential sidewall of the piston 33 to ensure reliable assembly of the cylinder seal 37, thereby improving sealing reliability.

[0115] Further, in this embodiment, as shown in Figures 13 and 15, the cylinder seal 37 is formed as an annular structure, having a fifth through hole (also referred to as a seal through hole) 373 and a fifth groove (also referred to as a seal groove) 354. The opening of the fifth groove 354 faces the second side 332, and the piston 33 passes through the fifth through hole 373, such that at least a portion of the cylinder seal 37 is fitted between the first side 331 and the second side 332. Exemplarily, the fifth groove 354 has a first arm 3541 and a second arm 3542. The distance from the axis of the first arm 3541 to the fifth through hole 373 is less than the distance from the axis of the second arm 3542 to the fifth through hole 373. The piston receiving space 3300 is used to receive at least a portion of the first arm 3541, and the length of the first arm 3541 in the direction of movement of the piston 33 is less than or equal to the length of the second arm 3542 in the direction of movement of the piston 33. In another example, the cylinder seal 37 is disposed between the plane of the first surface 3311 and the plane of the second surface 3321.

[0116] Furthermore, the cylinder seal 37 has a first end face 371 and a second end face 372, with the first end face 371 disposed near the first side portion 331 and the second end face 372 disposed near the second side portion 332. Exemplarily, the cross-sectional area of ​​the second end face 372 is larger than the cross-sectional area of ​​the first end face 371. In another exemplary embodiment, the distance from the outer edge of the projection of the first end face 371 onto the second end face 372 to the center of the second end face 372 is less than or equal to the distance from the outer edge of the second end face 372 to the center of the second end face 372. In an optional embodiment, the cross-section of the cylinder seal 37 parallel to the direction of movement of the piston 33 is trapezoidal, such that the circumferential sidewall of the cylinder seal 37 is inclined, to satisfy the structure that the cross-sectional area of ​​the second end face 372 is larger than the cross-sectional area of ​​the first end face 371. In another alternative embodiment, in the axial direction of the cylinder seal 37, the middle portion of the circumferential sidewall of the cylinder seal 37 protrudes beyond the portions at both ends of the circumferential sidewall of the cylinder seal 37, so that the cylinder seal 37 is formed with a structure that is high in the middle and low at both ends, and the high portion in the middle can abut against the sidewall of the cylinder 34.

[0117] In this embodiment, as shown in Figures 1 to 6 and Figure 17, the emergency equipment further includes a second power unit 40 and a second one-way valve 4010. The connecting pipe 10 includes a first air pipe 101 and a second air pipe 102. The first air pipe 101 is disposed inside the second air pipe 102. Specifically, the first air pipe 101 is formed into a cylindrical hole structure, and the second air pipe 102 is formed into an annular hole structure. The first air pipe 101 is disposed inside the second air pipe 102, that is, the second air pipe 102 surrounds the circumference of the first air pipe 101. The second air pipe 102 has a larger cross-sectional area than the first air pipe 101. The detection unit 13 is connected to the first air pipe 101. The connecting pipe 10 has a second air inlet 130 and a second air outlet 140. The second air inlet 130 has a second air inlet 131 and the second air outlet 140 has a second air outlet 141. The first air pipe 101 has a first air inlet 111 and a first air outlet 121. The second air pipe 102 has a second air inlet 131 and a second air outlet 141.

[0118] Specifically, as shown in Figures 1, 3, and 17, the second power unit 40 includes a second housing 401. The second housing 401 has a high-flow-rate air inlet 42 and a high-flow-rate air outlet 41. The high-flow-rate air outlet 41 is connected to the second air inlet 130 and has a high-flow-rate air outlet 411. The high-flow-rate air outlet 41 and the connecting pipe 10 form a high-flow-rate accommodating space 4001. A second one-way valve 4010 is disposed in the high-flow-rate accommodating space 4001 to allow the second power unit 40 to provide a second airflow to the second air outlet 140. The second airflow flows from the second air inlet 131 of the second air inlet 130 to the second air outlet 141 of the second air outlet 140. The second one-way valve 4010 has a sixth protrusion 4011, and the large flow outlet 41 has a second through hole 412. The sixth protrusion 4011 passes through the second through hole 412, and the second through hole 412 guides the movement of the second one-way valve 4010 in the large flow receiving space 4001. When the second power unit 40 provides the second airflow to the second outlet 140, the sixth protrusion 4011 is located in the second through hole 412.

[0119] It should be noted that the second power unit 40 includes a second drive component and a second air-filling component (not shown in the figure). The second drive component can be a brushed motor or a brushless motor, and the second air-filling component is a fan blade. The motor and fan blade can be selected according to actual needs. After assembling the fan blade with the motor, it is installed in the second housing 401. When the motor is working, it can draw in air from the high-flow air intake 42 to form a second airflow.

[0120] In this embodiment, the air pump 6 can output both high-flow-rate gas and high-pressure gas, thus meeting the needs of paddleboard inflation and car tire inflation. When inflating the paddleboard, the initial air pressure is low, and the second power unit 40 outputs a high-flow-rate gas to the paddleboard. When the paddleboard air pressure is high and the inflation volume of the second power unit 40 decreases significantly, the second power unit 40 is turned off, and the first power unit 30 is started to output high-pressure gas to the paddleboard until the paddleboard reaches the expected high air pressure value. This greatly shortens the inflation time, thereby improving inflation efficiency and avoiding the situation where the first power unit 30 overheats and is damaged due to direct activation. When inflating car tires, the first power unit 30 is directly activated to output high-pressure gas to the car tires until the expected high air pressure value is reached, thus meeting the different inflation needs of users.

[0121] In this embodiment, the air pressure of the first airflow is greater than that of the second airflow, thus ensuring that the first airflow can meet the high-pressure inflation requirements of the car tires.

[0122] Furthermore, within a unit time, the volume of the second airflow passing through the high-flow-rate outlet 411 is greater than the volume of the first airflow passing through the cylinder outlet 352, or the cross-sectional area of ​​the high-flow-rate outlet 411 is greater than the cross-sectional area of ​​the cylinder outlet 352, so that the second power unit 40 can output a large flow of gas to the paddle, while the first power unit 30 can output high-pressure gas to the car tires or paddle.

[0123] Specifically, the first air pipe 101 includes a first sub-first air pipe 1011, a second sub-first air pipe 1012, and a third sub-first air pipe 1013 connected in sequence. The first sub-first air pipe 1011 includes a first air inlet 111, which includes a first sub-first air inlet 1111 and a second sub-first air inlet 1112. The cross-sectional area of ​​the first sub-first air inlet 1111 is larger than that of the second sub-first air inlet 1112. The first sub-first air pipe 1011 and the cylinder outlet 35 form a first accommodating space 112. The cross-sectional area of ​​the third sub-first air pipe 1013 is larger than that of the second sub-first air pipe 1012.

[0124] In a preferred embodiment, the first air pipe 101 and the second air pipe 102 are coaxial or substantially coaxial, or the first air outlet 121 and the second air outlet 141 are coaxial or substantially coaxial, so as to ensure the structural rationality and aesthetics of the air pump 6.

[0125] Further, in this embodiment, as shown in Figures 3 and 4, the first air pipe 101 also includes a fourth sub-first air pipe 1014 and a fifth sub-first air pipe 1015 connected in sequence. The fourth sub-first air pipe 1014 includes a first air outlet 121. The first air outlet 121 includes a first sub-first air outlet 1211 and a second sub-first air outlet 1212.

[0127] In a preferred embodiment, as shown in Figures 3 and 4, an air pipe seal 70 is provided inside the fourth sub-first air pipe 1014. The air pipe seal 70 is formed into an annular structure and has a third through hole 71 inside. The air pipe seal 70 is used for sealing the connection between the inflation device and the device to be inflated, so as to ensure that the external air pipe 90 is tightly and reliably connected to the fourth sub-first air pipe 1014, thereby avoiding air leakage at the connection between the fourth sub-first air pipe 1014 and the external air pipe 90.

[0128] Specifically, in a preferred embodiment, as shown in Figures 3 and 4, the diameter of the third through hole 71 is smaller than the diameter of the second sub-first air outlet 1212, which to some extent increases the gas pressure of the second sub-first air outlet 1212 and strengthens the airtightness between the fourth sub-first air pipe 1014 and the external air pipe 90.

[0129] In a preferred embodiment, as shown in FIG4, the connecting pipe 10 includes a first connecting pipe 11 and a second connecting pipe 12, thus forming a split structure in which the connecting pipe 10 is divided into two parts along the axial direction. Along the flow direction of the first airflow or the second airflow, the first connecting pipe 11 is located upstream of the second connecting pipe 12, so that the first connecting pipe 11 has a first air inlet 110 and a second air inlet 130, thereby facilitating the assembly of the first power unit 30, the second power unit 40 and the connecting pipe 10; the second connecting pipe 12 has a first air outlet. 120 and the second air outlet 140, the first connecting pipe 11 and the second connecting pipe 12 are detachably connected, the first inflation assembly 311 is provided with a detection part 13 near the connection between the first cylinder assembly 32 and the first connecting pipe 11, the cylinder air outlet 35 and the first connecting pipe 11 form a first receiving space 112, the first airflow flows from the first air inlet 110 through the first air outlet 120, the large flow air outlet 41 and the first connecting pipe 11 form a large flow receiving space 4001, and the second airflow flows from the second air inlet 130 through the second air outlet 140.

[0130] In this embodiment, as shown in Figures 1 and 19, the first drive assembly 31 includes a motor 3003 and a second protective member 3001. The motor 3003 has a first connecting portion 3002 on the side facing the second protective member 3001. The second protective member 3001 covers the motor 3003 and can display relevant information about the motor 3003 on the second protective member 3001, and also protects the motor 3003. The second protective member 3001 has a second connecting portion 3004 on the side facing the motor 3003. The first connecting portion 3002 and the second connecting portion 3004 are engaged. The second protective member 3001 also has a first opening 3005, which is for easy installation of the second protective member 3001 onto the motor 3003. For example, the motor 3003 has a first connecting part 3002 at one end near the first inflation component 311, and the cross-section of the second protective member 3001 is C-shaped or substantially C-shaped, which is perpendicular to the rotation axis of the motor 3003. The first connecting part 3002 is a groove or an opening, and the second connecting part 3004 is a protrusion that can extend into the groove or opening.

[0131] In this embodiment, as shown in Figures 3, 6, 12, and 13, the first cylinder assembly 32 includes a connecting rod 36, a piston 33, and a cylinder 34. Specifically, the connecting rod 36 includes a rotating part 361, a rod body 362, and a piston connecting part 363. The rotating part 361 includes a first end 3611 and a second end 3612, which are arranged opposite to each other. The rotating part 361 is connected to the first transmission assembly 3111, and the piston connecting part 363 is connected to the piston 33. The plug 33 is disposed inside the cylinder 34. The rod body 362 includes a first surface 3621 and a second surface 3622. The first surface 3621 and the second surface 3622 are perpendicular or substantially perpendicular to the axis of the rotating part 361, respectively. The first surface 3621 and the second surface 3622 are arranged opposite to each other. The distance from the plane where the first end 3611 is located to the first surface 3621 is not equal to the distance from the plane where the second end 3612 is located to the second surface 3622, thus satisfying the layout requirements and force requirements of the first cylinder assembly 32.

[0132] More specifically, as shown in Figures 12 and 13, the distance from the plane of the first end 3611 to the first surface 3621 is less than the distance from the plane of the second end 3612 to the second surface 3622. This ensures the load-bearing capacity of the connecting rod 36, thereby increasing the service life of the air pump 6. The first end 3611 has a seventh protrusion 36111, which is a ring structure, facilitating the movement of the rotating part 361.

[0133] In this embodiment, as shown in Figures 3, 6 and 12, the rod body 362 includes a reinforcing surface 3623 and a first reinforcing rib 381. The reinforcing surface 3623 is parallel or substantially parallel to the axis of the rotating part 361. The first reinforcing rib 381 is disposed on the reinforcing surface 3623 and connected to the piston 33. For example, the rod body 362 includes two reinforcing surfaces 3623 and two first reinforcing ribs 381. Each reinforcing surface 3623 is provided with a first reinforcing rib 381. The two reinforcing surfaces 3623 are disposed opposite each other between the first surface 3621 and the second surface 3622. The first reinforcing rib 381 is connected to the piston 33. Preferably, the first reinforcing rib 381 can be a triangular plate structure or a strip rod structure, so that the first reinforcing rib 381, the reinforcing surface 3623 and the piston 33 form a triangular structure to improve the connection strength between the connecting rod 36 and the piston 33. When the first reinforcing rib 381 is a triangular plate structure, the two sides of the triangle are connected to the reinforcing surface 3623 and the piston 33 respectively. When the first reinforcing rib 381 is a strip rod structure, the two ends of the rod structure in the length direction are connected to the reinforcing surface 3623 and the piston 33 respectively.

[0134] In a preferred embodiment, the projection of the end of the first reinforcing rib 381 away from the piston 33 onto the piston 33 falls within the contact area between the piston 33 and the first reinforcing rib 381.

[0135] In this embodiment, as shown in Figures 12 and 13, the rod body 362 includes a first surface 3621 and a second surface 3622. The first surface 3621 is perpendicular or substantially perpendicular to the axis of the rotating part 361. The first surface 3621 and the second surface 3622 are arranged opposite to each other. The distance between the plane where the first reinforcing rib 381 is located and the first surface 3621 is less than the distance between the plane where the first reinforcing rib 381 is located and the second surface 3622, thus ensuring the structural strength of the connecting rod 36.

[0136] In this embodiment, as shown in Figures 3, 6, 12, 13, and 16, the first cylinder assembly 32 includes a connecting rod 36, a piston 33, and a cylinder 34. The connecting rod 36 includes a sixth groove (also referred to as a rod groove) 383 and a second reinforcing rib 382. The sixth groove 383 serves to reduce weight, and the second reinforcing rib 382 is disposed within the sixth groove 383. The piston 33 has a first side portion 331 and a second side portion 332. The first side portion 331 is connected to the connecting rod 36, and the second side portion 332 is disposed opposite to the first side portion 331. The first side portion 331 has a first surface 3311 on the side facing the second side portion 332, and the second reinforcing rib 382 is parallel or substantially parallel to the first surface 3311. For example, the sixth groove 383 may be formed by inwardly recessing the first surface 3621 and / or the second surface 3622 as described above; the sixth groove 383 has a second reinforcing rib 382 extending in the first direction, that is, the second reinforcing rib 382 is formed as a strip structure extending along the first direction to ensure that the connecting rod 36 with the sixth groove 383 has sufficient structural strength. In this embodiment, the first direction is perpendicular to the movement direction of the piston 33.

[0137] In this embodiment, as shown in Figures 3, 7, 9, and 14, a connecting port 1003 is formed at the connection between the first air passage 1001 and the second air passage 1002. The distance between the connecting port 1003 and the cylinder outlet 352 in the direction of piston 33 movement is greater than or equal to 0.5 cm and less than or equal to 2 cm, so that the air pump 6 can be miniaturized and lightweight, and the structure is reasonable. That is, when the detection part 13 is located on the cylinder 34, the distance between the connecting port 1003 and the cylinder outlet 352 in the direction of piston 33 movement is at least 0.5 cm, so that the air pump 6 can provide space for fixing the detection component 20. When the detection part 13 is located on the connecting pipe 10, the distance between the connecting port 1003 and the cylinder outlet 352 in the direction of piston 33 movement is at most 2 cm, so that the air pump 6 can provide a first accommodating space 112 that meets the requirements. The setting of the distance between the connecting port 1003 and the cylinder outlet 352 in the direction of piston 33 movement plays an important role in meeting the functional requirements of the air pump 6 while also contributing to miniaturization and weight reduction. For example, the distance between the connecting port 1003 and the cylinder outlet 352 in the direction of piston 33 movement is equal to 0.5cm or 1.5cm.

[0138] According to the emergency equipment provided in this application, the internal power supply can output a first current to the vehicle, and the first power unit outputs a first airflow, thus integrating the inflation device and the vehicle's emergency starting power supply. This allows the device to be used as an emergency power source to start the vehicle while simultaneously meeting inflation needs. The detection component can detect air pressure information to meet the different air pressure requirements during inflation. Furthermore, the inflation pump can output a first airflow and a second airflow to achieve the output of large-flow and high-pressure gas, thus meeting the needs of paddleboard inflation and vehicle tire inflation. When inflating the paddleboard, the initial air pressure value is low, and the second... The second power unit outputs a large flow of gas to the paddle plate. When the paddle plate pressure is high and the inflation volume of the second power unit decreases significantly, the second power unit is turned off, and the first power unit is activated to output high-pressure gas to the paddle plate until the paddle plate reaches the expected high pressure value. This greatly shortens the inflation time, thereby improving inflation efficiency and avoiding the situation where the first power unit overheats and is damaged due to direct activation. When inflating car tires, the first power unit is directly activated to output high-pressure gas to the car tires until the expected high pressure value is reached, thus meeting different inflation needs of users.
