[0030] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0031] Please see Figures 1 to 3 ,like Figure 1 , Figure 2 and Figure 3 As shown in the figure, this application embodiment proposes a handheld air blower, which may include: a housing 10, a blowing assembly 20, an emergency battery 31, and a circuit board 41.

[0032] The housing 10 may include a receiving cavity 10a, which may include a first receiving cavity 1001 and a second receiving cavity 1002.

[0033] For example, the housing 10 may include an air outlet 11 extending in a first direction and a gripping portion 12 extending in a second direction, the air outlet 11 corresponding to a first receiving cavity 1001 and the gripping portion 12 corresponding to a second receiving cavity 1002.

[0034] In some embodiments, the grip portion 12 may be foldable.

[0035] In some embodiments, the first direction and the second direction may form a preset angle, and the value of the preset angle may be in the range of 60°-150°.

[0036] It is understandable that by providing an air outlet 11 and a grip 12 on the housing 10, or by setting a preset range of included angles, it is possible to make it convenient for the user to hold the device. By providing a foldable grip 12 on the handheld air blower, it is possible to make it easier for the user to store the handheld air blower while ensuring that it is convenient for the user to hold the device.

[0037] In some embodiments, the housing 10 may include a first housing 101 and a first housing 102, which are detachably connected to form a receiving cavity 10a.

[0038] It is understandable that the detachable design of the first housing 101 and the first housing 102 facilitates users and manufacturers to disassemble, install, repair, debug, clean, and modify the handheld air blower.

[0039] The blower assembly 20 can be disposed within the first receiving cavity 1001.

[0040] In some embodiments, the blower assembly 20 may include an air pump, and the handheld blower may also include a tire pressure sensor and an air inflator connector, the tire pressure sensor being disposed on the air inflator connector and the air inflator connector being connected to the air pump.

[0041] Understandably, the user or device can monitor the tire pressure through the tire pressure sensor, and when the tire pressure value reaches the target range, it can promptly obtain the relevant signal and stop inflating. This not only improves the practicality of the handheld air blower, but also ensures the safety, stability and accuracy of the inflating process.

[0042] It can be further understood that users can also use tire pressure sensors to check for tire leaks and other issues.

[0043] In other embodiments, the blower assembly 20 may include a blower motor 21 and a blower sleeve 23, the blower sleeve 23 being disposed around the blower motor 21.

[0044] For example, the housing 10 may be provided with one of a first rotating bracket 11a and a first rotating latch 11c in the first receiving cavity 1001. The other of the first rotating bracket 11a and the first rotating latch 11c may be correspondingly provided on the periphery of the fan sleeve 23. The first rotating latch 11c may cooperate with the first rotating bracket 11a to connect the fan sleeve 23 to the housing 10.

[0045] Understandably, the blower motor 21 and blower sleeve 23 enable the handheld air blower to perform blowing or blowing functions, making it convenient for users to use the handheld air blower to complete tasks such as blowing dust and snow off vehicles, inflating tents and sleeping bags, and blowing air in outdoor or transportation scenarios, thus improving the performance of the handheld air blower.

[0046] It can be further understood that the design of the fan sleeve 23 not only facilitates the installation and fixation of the blower motor 21, but also restricts the gas flow channel and isolates the gas flow channel from the receiving cavity 10a. This not only improves the wind power output efficiency, but also prevents the blower motor 21 from bringing impurities in the air into the receiving cavity 10a during operation.

[0047] It can be further understood that the design of the rotating bayonet and rotating base can facilitate and simplify the processes of disassembly, assembly, maintenance, and cleaning, thereby reducing various costs and making it more convenient for users.

[0048] In some embodiments, the blower assembly 20 may further include a filter 22, the air outlet 11 may be provided with a second air outlet 10c and a first air outlet 10b corresponding to each other along a first direction, the first receiving cavity 1001 may be connected to the second air outlet 10c and the first air outlet 10b, and the filter 22 may be provided at the second air outlet 10c and / or the first air outlet 10b.

[0049] The gas flow channel inlet of the blower assembly 20 can correspond to the second air outlet 10c, and the gas flow channel outlet of the blower assembly 20 can correspond to the first air outlet 10b.

[0050] In some embodiments, the housing 10 is provided with one of a second rotating bracket 11b and a second rotating latch 11d in the first receiving cavity 1001. The other of the second rotating bracket 11b and the second rotating latch 11d is correspondingly disposed on the filter screen 22. The second rotating latch 11d cooperates with the second rotating bracket 11b to connect the filter screen 22 to the housing 10.

[0051] Understandably, the design of filter 22 prevents users from accidentally inserting their fingers or bringing impurities into the gas flow channel, thereby causing damage to the equipment and the user.

[0052] The emergency battery cell 31 can be installed in the second receiving cavity 1002.

[0053] Specifically, an emergency interface 32 can be provided in the grip part 12. The emergency interface 32 is electrically connected to the emergency battery cell 31 and can be used for emergency start-up.

[0054] It is understandable that in vehicle use scenarios, especially for long-distance freight or passenger transport, users face many restrictions on wiring, cable management, and usage posture when using wired air blowers for cleaning, snow blowing, blowing, or air pumping. This can also lead to risks such as wire tangling and create electrical hazards.

[0055] It can be further understood that emergency power equipment is a readily available, simple, and easily accessible source of power in vehicle use scenarios. This handheld air blower uses an emergency battery cell 31 as its power source, cleverly combining the air blower with the emergency power equipment. It not only realizes the function of the air blower, but also facilitates user use through the design of the grip part 12, and the structure is made more compact through the design of the receiving cavity 10a. Thus, the handheld air blower has the advantages of practical function, compact structure, and ease of use.

[0056] In some embodiments, the circuit board 41 may be disposed within the receiving cavity 10a, and the circuit board 41 may be electrically connected to the blower assembly 20 and the battery cell.

[0057] Understandably, the circuit board 41 can be divided into a first circuit board 41 and a second circuit board 41 according to actual functional needs. On the one hand, this reduces the overall size of the circuit board 41 and facilitates the installation of the circuit board 41 and other electrical components. On the other hand, it makes the foldable design of the grip part 12 possible, so that the circuit board 41 will not be damaged due to folding, or the circuit board 41 will need to be further miniaturized, thereby increasing the cost.

[0058] It can be further understood that at least one of the first circuit board 41 and the second circuit board 41 can be disposed in the first receiving cavity 1001, the second receiving cavity 1002, or the connection between the first receiving cavity 1001 and the second receiving cavity 1002.

[0059] For example, the housing 10 may be provided with at least one fixing plate 131 and multiple fixing members 132 in the second receiving cavity 1002. The fixing plate 131 and multiple fixing members 132 form a placement groove 133, and the emergency battery 31 is installed in the placement groove 133.

[0060] One side of the fixing plate 131 can be used to set the circuit board 41, and the other side of the fixing plate 131 can be connected to the emergency battery cell 31.

[0061] Understandably, by using the surfaces of the fixing plate 131 and the fixing member 132 to fix the electrical components, the internal electrical components of the handheld air blower are arranged more compactly and neatly, which not only facilitates installation and disassembly, but also enhances the overall structural compactness of the handheld air blower.

[0062] It can be further understood that by forming a placement groove 133 with the fixing plate 131 and the fixing member 132, and installing the emergency battery 31 in the placement groove 133, damage to the emergency battery 31 caused by external vibration or collision can be reduced, thereby further improving the safety and stability of the handheld air blower.

[0063] In some embodiments, the housing 10 may also be provided with an indicator light and / or a display screen, which are electrically connected to the circuit board 41 for displaying the working information of the handheld air blower.

[0064] This work information may include tire pressure information, equipment battery level, etc.

[0065] Understandably, when using this handheld air blower to inflate or blow air, users can determine when to stop the inflating or blowing operation by using the tire pressure information and device power information provided by the indicator lights or display screen.

[0066] Without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of the different embodiments or examples.

[0067] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
