Description

Technical Field

[0001] The utility model relates to the technical field of emergency power supplies, in particular to an automobile emergency starting power supply with an inflation function. Background Art

[0002] As a common means of transportation, cars occupy an important position in people's lives. As the car moves, the amount of air 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. Paddle boards are a type of water sports equipment. Compared with hard paddle boards, inflatable paddle boards have the advantages of being foldable when deflated, which makes them easy to transport and store. When in use, they can be inflated using a paddle board inflation device, and are therefore becoming increasingly popular among water sports enthusiasts.

[0003] Existing automobile inflators, designed to address issues such as cylinder sealing and accurate air pressure detection, have an unreasonable structure. Furthermore, the existing automobile inflator, automobile emergency starting power supply, and paddle board inflator are separate products. Using the automobile inflator to inflate a paddle board takes a long time because the gas flow rate output by the automobile inflator is too low, which can easily cause the inflator to overheat and become damaged. Furthermore, the air pressure generated by the paddle board inflator is too low to inflate the tires. Therefore, the existing inflator structure is unreasonable and cannot meet diverse inflation requirements. Utility Model Content

DETAILED DESCRIPTION

[0082] The following detailed description is presented to aid in understanding the method, apparatus and / or system described herein. It is not intended to limit the method, apparatus and / or system described herein to the precise construction described. Rather, various changes, modifications, and equivalents can be resorted to as will be apparent to those skilled in the art. For example, the order of the operations described herein can be changed, except that the operations must occur in the order in which they are described unless otherwise stated. In addition, features described herein can be omitted for the sake of brevity and clarity.

[0083] The features described herein can be implemented in different forms and should not be construed as limited to the examples described herein. Rather, these examples have been provided so that this disclosure will be thorough and complete, and will fully convey the scope of the method, apparatus and / or system to those skilled in the art. Further, the description should not be construed as limiting the method, apparatus and / or system described herein to the examples presented herein. Rather, the description is intended to cover any alternatives, modifications, and equivalents, which can be made to the examples presented herein, including practices or processes known in the art.

[0084] Throughout the specification, when an element (such as a layer, region, or substrate) is referred to as being "on" another element, "connected to" another element, "coupled to" another element, "adjacent to" another element, "on top of" another element, or "covering" another element, it can be directly on, connected to, coupled to, adjacent to, on top of, or covering the other element, or one or more other elements can be interposed therebetween. In contrast, when an element is referred to as being "directly on," "directly connected to," "directly coupled to," "directly adjacent to," "directly on top of," or "directly covering" another element, there are no other elements interposed therebetween.

[0085] As used herein, the term "and / or" includes any one of the listed items and any combination of two or more of the listed items.

[0086] Although terms such as "first" and "second" and "third" can be used herein to describe various elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. Rather, these terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, elements, components, regions, layers and / or sections referred to as a first element, component, region, layer or section herein can also be referred to using a second element, component, region, layer or section, without departing from the teachings of the examples.

[0087] For ease of description, spatial terms such as "over," "upper," "under," and "lower" can be used with respect to the orientation of one element relative to another element as illustrated in the figures. Such spatial terms are intended to encompass different orientations of the device in use or operation, in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as being "over" or "upper" relative to other elements would then be oriented "under" or "lower" relative to the other elements. Accordingly, the term "over" encompasses both an "over" and an "under" orientation. The device can be oriented in other ways (e.g., rotated 90 degrees or at other orientations) and terms such as "over," "upper," "under," and "lower" used herein will be interpreted accordingly.

[0088] The terminology used herein is for the purpose of describing various examples only and is not intended to be limiting of the disclosure. As used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms "comprises," "comprising," "includes," "including" and "has" or "having" and the like are inclusive of the stated features, numbers, operations, components, elements, and / or the like, but do not exclude the presence or addition of one or more other features, numbers, operations, components, elements, and / or the like.

[0089] Variations in shapes depicted in the figures can occur as a result of manufacturing processes and / or tolerances. Thus, the examples described herein are not limited to the specific shapes described herein but include variations in shapes that occur during manufacturing.

[0090] Features of the examples described herein can be combined with features of other examples in accordance with the disclosure, as would be apparent to one of ordinary skill in the art after having the benefit of this disclosure. In addition, although a variety of examples have been described here, many suitable alternatives will be apparent to those of ordinary skill in the art after having the benefit of this disclosure. Furthermore, to the extent that there are "consensus" sequences of certain genes, those consensus sequences can be combined with features of the examples described herein.

[0122] In this embodiment, if Figures 1 to 6 、 Figure 17As shown, the automobile emergency starting power supply with an inflation function further includes a second power device 40 and a second one-way valve 4010, and the connecting pipe 10 includes a first air pipe 101 and a second air pipe 102. The first air pipe 101 is arranged in 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 arranged in the second air pipe 102, that is, the second air pipe 102 is arranged around the circumferential outside of the first air pipe 101, so that The cross-sectional area of ​​the second air pipe 102 is greater than the cross-sectional area of ​​the first air pipe 101, and the detection part 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, 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, and the second air pipe 102 has a second air inlet 131 and a second air outlet 141.

[0123] Specifically, if Figure 1 、 Figure 3 and Figure 17 The second power device 40 shown includes a second shell 401, the second shell 401 has a large flow air inlet 42 and a large flow air outlet 41, the large flow air outlet 41 is connected to the second air inlet 130, the large flow air outlet 41 has a large flow air outlet 411, the large flow air outlet 41 and the connecting pipe 10 form a large flow accommodating space 4001, and the second one-way valve 4010 is arranged in the large flow accommodating space 4001, which is used to allow the second power device 40 to provide a second air flow to the second air outlet 140, and the second air flow 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 air outlet portion 41 has a second through hole 412. The sixth protrusion 4011 passes through the second through hole 412. The second through hole 412 guides the movement of the second one-way valve 4010 in the large-flow accommodating space 4001. When the second power device 40 provides the second air flow to the second air outlet portion 140, the sixth protrusion 4011 is in the second through hole 412.

[0124] It should be noted that the second power device 40 includes a second drive component and a second inflation component (not shown in the figure). The second drive component can be a brushed motor or a brushless motor. The second inflation component is a fan blade. The motor and fan blades can be selected according to actual needs. After the fan blades are assembled with the motor, they are installed in the second shell 401. When the motor is working, air can be inhaled from the large-flow air intake 42 to form a second airflow.

[0125] In this embodiment, the air pump 6 can output both high-flow gas and high-pressure gas, thus meeting the needs of inflating the paddle board and the car tire; when inflating the paddle board, the initial air pressure value of the paddle board is low, and the second power device 40 outputs a large flow of gas to the paddle board. When the air pressure value of the paddle board is high and the inflation volume of the second power device 40 is greatly reduced, the second power device 40 is turned off, and the first power device 30 is started to output high-pressure gas to the paddle board until the paddle board reaches the expected high pressure value, which greatly shortens the inflation time, improves the inflation efficiency, and avoids the situation where the first power device 30 is overheated and damaged due to direct activation of the first power device 30; and when inflating the car tire, the first power device 30 is directly started to output high-pressure gas to the car tire until the expected high pressure value is reached, thereby meeting the different inflation needs of users.

In addition, the inflator can output the first airflow and the second airflow to output the high-flow gas and the high-pressure gas, so that the paddleboard inflating and the automobile tire inflating are met. When the paddleboard is inflated, the initial air pressure value of the paddleboard is low, the second power device outputs the high-flow gas to the paddleboard, when the air pressure value of the paddleboard is high and the inflating amount of the second power device is greatly reduced, the second power device is closed, and the first power device is started to output the high-pressure gas to the paddleboard until the paddleboard reaches the expected high air pressure value, so that the inflating time is greatly shortened, the inflating efficiency is improved, and the situation that the first power device is damaged due to overheating during operation is avoided. When the automobile tire is inflated, the first power device is directly started to output the high-pressure gas to the automobile tire until the expected high air pressure value is reached, so that different inflating demands of users are met.
