[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0045] Please see Figures 1 to 4This utility model provides an air blower, including a housing 10, an energy storage component 30, a blowing component 20, and a flow guide 60. The energy storage component 30 is disposed on the housing 10 and has an emergency interface 32 for electrical connection to a vehicle to enable emergency starting. The blowing component 20 is disposed on the housing 10 and electrically connected to the energy storage component 30, and has an air outlet 20a. The flow guide 60 is connected to the housing 10 or the blowing component 30 and is correspondingly positioned to adjust the airflow effect at the air outlet 20a.

[0046] In this embodiment of the air blower, the energy storage component 30 supplies power to the blowing component 20, enabling the blowing component 20 to operate normally and output air, thus giving the air blower an air output function. The guide component 60 is correspondingly arranged with the air outlet 20a, allowing the guide component 60 to adjust the airflow effect at the air outlet 20a, such as adjusting the airflow speed and range, to improve the working efficiency of the air blower when performing dust removal or drying. Furthermore, the energy storage component 30 also has an emergency interface 32, which can be electrically connected to a vehicle to enable emergency starting, giving the air blower an emergency start function. This facilitates the diversification of the air blower's functions, improves its applicability, and meets different user needs.

[0047] For example, dust and debris easily accumulate in areas such as car door seams and window seams. By using a deflector to adjust the airflow at the air outlet 20a, the airflow from the blower becomes more concentrated, allowing the airflow to penetrate deeper into the gaps and blow away the dust and debris. Alternatively, when there is a large amount of water or snow on the car body surface, using a deflector to adjust the airflow at the air outlet 20a increases the airflow range of the blower, enabling it to blow away the water or snow from the car body surface more quickly.

[0048] For example, the air blower can be connected to the positive and negative terminals of a car battery via an emergency interface 32 to enable emergency start-up using the air blower's energy storage component 30.

[0049] like Figure 3 and Figure 4 As shown, in some embodiments, the housing 10 has a receiving cavity 10a, in which the blowing assembly 20 and / or the energy storage assembly 30 may be disposed, and the housing 10 can protect the blowing assembly 20 and / or the energy storage assembly 30.

[0050] For example, such as Figure 4 As shown, the housing 10 includes a first housing 101 and a second housing 102, which are connected and enclosed to form a receiving cavity 10a.

[0051] For example, the first housing 101 and the second housing 102 can be connected by a snap-fit ​​mechanism, or the first housing 101 and the second housing 102 can be fastened together by fasteners.

[0052] In some embodiments, the housing 10 has a first air vent 10b and a second air vent 10c that connect to the receiving cavity 10a. A guide member 60 may be disposed on the outer periphery of the second air vent 10c. A blowing assembly 20 is disposed in the receiving cavity 10a. The blowing assembly 20 can draw in external air through the first air vent 10b to form an airflow and output it from the air outlet 20a of the blowing assembly 20. The output airflow reaches the guide member 60 after passing through the second air vent 10c, so that the guide member 60 can adjust the airflow output effect.

[0053] For example, the first air vent 10b and the second air vent 10c are arranged opposite each other, or the first air vent 10b and the second air vent 10c may be located on adjacent sides of the housing 10.

[0054] For example, such as Figure 3 As shown, the second air vent 10c, the first air vent 10b, and the energy storage component 30 are located on different sides of the air blowing component 20 to prevent the energy storage component 30 from blocking airflow.

[0055] For example, the first housing 101 and the second housing 102 can be enclosed to form a first air vent 10b, and the first housing 101 and the second housing 102 can be enclosed to form a second air vent 10c.

[0056] like Figure 4 As shown, in some embodiments, the blower assembly 20 includes a blower motor 21 and a fan sleeve 33 connected to the blower motor 21. The fan sleeve 33 has a gas flow channel with an air outlet 20a. The air outlet 20a can be correspondingly set with the second air outlet 10c so that the gas flow channel can guide the drawn-in air to the second air outlet 10c and realize the air outlet via the guide member 60.

[0057] Furthermore, the blower assembly also includes a filter screen 22, which can be located on the side of the blower motor 21 away from the blower motor 21 sleeve 33, and on the side of the blower sleeve 33 away from the blower motor 21. The filter screen 22 can prevent debris from entering the blower motor 21. The mesh structure of the filter screen 22 can be adjusted according to the actual situation.

[0058] In some embodiments, the housing 10 is snapped onto the blower assembly 20, and / or the housing 10 is glued to the blower assembly 20 to achieve the installation and fixation of the blower assembly 20.

[0059] For example, the blower motor 21, the blower sleeve 33 and the filter screen 22 of the blower assembly 20 are respectively snapped between the first housing 101 and the second housing 102, so that the blower assembly 20 is stably connected to the housing 10 as a whole.

[0060] like Figure 4 As shown, in some embodiments, the first housing 101 and / or the second housing 102 are provided with a first protrusion 1011 on the side near the receiving cavity 10a. The first protrusion 1011 is located between the blower assembly 20 and the first housing 101 and / or the second housing 102, so that the blower assembly 20 is at least partially spaced from the first housing 101 and / or the second housing 102, so as to facilitate the blower assembly 20 to dissipate heat.

[0061] For example, there are multiple first protrusions 1011, and the multiple first protrusions 1011 are spaced apart.

[0062] For example, such as Figure 4 As shown, the shape of a portion of the first protrusion 1011 can match the outer contour of the blower motor 21, so that the blower motor 21 can stably abut against the first protrusion 1011, achieving a stable engagement between the blower motor 21 and the housing 10. For example, if the outer contour of the blower motor 21 is arc-shaped, the first protrusion 1011 can be an arc-shaped protrusion. The shape of a portion of the first protrusion 1011 can also match the outer contour of the fan sleeve 33, so that the outer contour of the fan sleeve 33 matches the first protrusion 1011, achieving a stable engagement between the fan sleeve 33 and the housing 10. For example, if the outer contour of the fan sleeve 33 is arc-shaped, the first protrusion 1011 can be an arc-shaped protrusion.

[0063] In some embodiments, the air blower also includes a control component 40, which is electrically connected to the blowing component 20 and the energy storage component 30. The control component 40 is used to control the start and stop of the blowing component 20, so that the state of the blowing component 20 is controllable.

[0064] For example, the control component 40 may be disposed within the receiving cavity 10a so that the housing 10 can protect the control component 40.

[0065] In some embodiments, the energy storage component 30 is disposed within the housing 10a, and the housing 10 has a power transmission port 10d communicating with the housing 10a. The emergency interface 32 of the energy storage component 30 is connected to the power transmission port 10d, so that the emergency interface 32 of the energy storage component 30 can be electrically connected to the vehicle through the power transmission port 10d.

[0066] like Figure 4As shown, in some embodiments, the air blower also includes an insulating sleeve 50, which is movably connected to the housing 10 and is used to cover the power supply port 10d. When the emergency interface 32 is needed to start the vehicle in an emergency, the insulating sleeve 50 can be controlled to move relative to the housing 10 so that the power supply port 10d is exposed, facilitating electrical connection between the vehicle and the emergency interface 32. When the emergency interface 32 is not needed to start the vehicle in an emergency, the insulating sleeve 50 can be controlled to move relative to the housing 10 to cover the power supply port 10d. The insulating sleeve 50 covers the power supply port 10d, protecting the emergency interface 32 while preventing accidental activation.

[0067] For example, the insulating sleeve 50 may be made of insulating materials such as rubber or silicone.

[0068] It is understandable that the insulating sleeve 50 is movably connected to the housing 10, which can be manifested as: the insulating sleeve 50 is slidably connected to the housing 10, or the insulating sleeve 50 is rotatably connected to the housing 10, or the insulating sleeve 50 is detachably connected to the housing 10.

[0069] For example, such as Figure 4 As shown, the housing 10 is provided with a mounting groove 10e. The bottom surface of the mounting groove 10e is connected to the power transmission port 10d. The insulating sleeve 50 can be snapped into the mounting groove 10e so that the insulating sleeve 50 can cover the power transmission port 10d. At the same time, the insulating sleeve 50 can be removed from the mounting groove 10e to expose the power transmission port 10d.

[0070] For example, the insulating sleeve 50 is provided with an operating part, which is at least partially located outside the mounting groove 10e, so that the user can press the operating part to remove the insulating sleeve 50 from the mounting groove 10e to expose the power supply port 10d.

[0071] like Figure 3 and Figure 4 As shown, in some embodiments, the insulating sleeve 50 is provided with a connecting part 51, and the bottom surface of the mounting groove 10e also has a connecting port that communicates with the receiving cavity 10a. One end of the connecting part 51 is connected to the insulating sleeve 50, and the other end passes through the connecting port and is located in the receiving cavity 10a. The outer diameter of the other end of the connecting part 51 is larger than the connecting port. The connecting part 51 is used to engage with the housing 10 to prevent the insulating sleeve 50 from being lost after it is removed from the mounting groove 10e.

[0072] In some embodiments, the air blower also includes a control component 40, which is electrically connected to the blowing component 20 and the energy storage component 30. The control component 40 is used to control the starting and stopping of the blowing component 20 and to control the power supply or de-energization of the energy storage component 30.

[0073] Furthermore, the control component 40 includes a circuit board 41, a first switch 42, and a second switch 43. The circuit board 41 is located on the housing 10 and is electrically connected to the blower assembly 20 and the energy storage assembly 30. The first switch 42 is electrically connected to the circuit board 41 and is used to control the power supply or de-energization of the energy storage assembly 30. The second switch 43 is electrically connected to the circuit board 41 and is used to control the start and stop of the blower assembly 20 when the energy storage assembly 30 is powered. Thus, the states of the energy storage assembly 30 and the blower assembly 20 can be regulated using the first switch 42 and the second switch 43 respectively. When the blower's blowing function is needed, the first switch 42 and the second switch 43 can be turned on; when the blower's emergency start function is needed, the first switch 42 can be turned on and the second switch 43 can be turned off.

[0074] For example, the first switch 42 includes, but is not limited to, a touch switch, a push switch, a knob, etc. The second switch 43 includes, but is not limited to, a touch switch, a push switch, a knob, etc.

[0075] For example, such as Figure 4 As shown, the first switch 42 includes a switch body 421 and a button 422. The switch body 421 can be disposed within the receiving cavity 10a. The housing 10 also has a first mounting hole communicating with the receiving cavity 10a. The button 422 is connected to the wall of the receiving cavity 10a and is correspondingly disposed with respect to the switch body 421. The button 422 partially passes through the first mounting hole and is located outside the housing 10, so that the user can press the button 422. When the user presses the button 422, the button 422 can deform and move closer to the switch body 421. After being triggered, the switch body 421 sends a signal to the circuit board 41. After receiving the signal, the circuit board 41 can perform the corresponding operation. The setting of the second switch 43 can refer to the setting of the first switch 42, and will not be described again here.

[0076] For example, the switch body 421 can be fastened to the circuit board 41 by fasteners, or the switch body 421 can be fixed to the circuit board 41 by soldering. The specific method can be adjusted according to the actual situation and is not limited here.

[0077] For example, the second switch 43 can also be used to adjust the airflow level of the blower assembly 20 when it is started.

[0078] For example, there may be one or more circuit boards 41. When there are multiple circuit boards 41, they are electrically connected to each other.

[0079] For example, circuit board 41 is snapped onto housing 10, and / or circuit board 41 is fastened to housing 10 by fasteners, and / or circuit board 41 is glued to housing 10. It is understood that circuit board 41 can be fixedly mounted on housing 10, and the fixing method of circuit board 41 is relatively flexible and can be adjusted according to actual conditions. For example... Figure 3 and Figure 4 As shown, a first snap-fit ​​member 1012 is provided on the side of the first housing 101 near the receiving cavity 10a. The first snap-fit ​​member 1012 forms a first slot, and the circuit board 41 can be snapped into the first slot to improve the connection stability between the circuit board 41 and the housing 10.

[0080] In some embodiments, the energy storage component 30 includes an emergency battery cell 31 and a connecting wire 33. The emergency battery cell 31 is disposed in the housing 10 and electrically connected to the control component 40. The connecting wire 33 is electrically connected to either the emergency battery cell 31 or the control component 40, and the connecting wire 33 has an emergency interface 32. The control component 40 is used to control the emergency battery cell 31 to supply or de-energize the connecting wire 33. It is understood that the connecting wire 33 having an emergency interface 32 makes the emergency interface 32 more flexible and convenient to adjust the position of the emergency interface 32 in the air blower according to actual conditions.

[0081] For example, there may be one or more connecting wires 33.

[0082] For example, such as Figure 3 and Figure 4 As shown, one end of the connecting wire 33 is electrically connected to the emergency battery cell 31, and the other end has an emergency interface 32. Understandably, when the energy storage component 30 is used to enable emergency starting of a vehicle, the energy storage component 30 requires a large output current. Therefore, the connecting wire 33 can be directly electrically connected to the emergency battery cell 31. The current output from the emergency battery cell 31 to the connecting wire 33 does not pass through the circuit board 41, thus protecting the circuit board 41 while ensuring a stable current output.

[0083] Of course, in other embodiments, the emergency interface 32 may also be directly provided on the emergency battery cell 31.

[0084] In some embodiments, the emergency interface 32 is connected to the housing 10.

[0085] For example, the emergency interface 32 can be connected to the housing 10 by adhesive bonding, and / or the emergency interface 32 can be connected to the housing 10 by snap-fit, so that the emergency interface 32 is stably disposed on the housing 10, facilitating electrical connection between the vehicle and the emergency interface 32. For example Figure 3 and Figure 4As shown, a second snap-fit ​​member 1013 is provided on the side of the first housing 101 near the receiving cavity 10a. The second snap-fit ​​member 1013 forms a second slot, and the emergency interface 32 can be snapped into the second slot to improve the connection stability between the emergency interface 32 and the housing 10.

[0086] In some embodiments, the emergency battery 31 is snapped into the housing 10, and / or the emergency battery 31 can be connected to the housing 10 by adhesive bonding to achieve the positioning and installation of the emergency battery 31.

[0087] For example, the emergency battery 31 can be snapped between the first housing 101 and the second housing 102.

[0088] like Figure 4 As shown, in some embodiments, a second protrusion 1014 is provided on the side of the first housing 101 and / or the second housing 102 near the receiving cavity 10a. The second protrusion 1014 is located between the energy storage component 30 and the first housing 101 and / or the second housing 102, so that the energy storage component 30 is at least partially spaced from the first housing 101 and / or the second housing 102, which facilitates heat dissipation of the energy storage component 30.

[0089] In some embodiments, the circuit board 41 and the emergency battery cell 31 are spaced apart to prevent the circuit board 41 from scratching the emergency battery cell 31 and affecting its normal use.

[0090] like Figure 2 and Figure 4 As shown, in some embodiments, the air blower also includes one or more charging / discharging ports 70, which can be electrically connected to the energy storage component 30 or the control component 40. The charging / discharging ports 70 enable the energy storage component 30 to be charged, and also enable the energy storage component 30 to charge terminal devices such as mobile phones and tablets, further diversifying the functions of the air blower.

[0091] For example, the charging / discharging port can be soldered to a circuit board for electrical connection to the circuit board.

[0092] like Figure 2 and Figure 3 As shown, in some embodiments, the housing 10 includes an air outlet 11 and a grip 12, with the air blowing assembly 20 disposed on the air outlet 11. This allows the user to easily grip the grip 12 and control the air blower to blow air in a specific direction when using it.

[0093] For example, the first switch 42 and the second switch 43 may be located at one end of the grip 12 near the air outlet 11, so that the user can operate the first switch 42 and the second switch 43 while holding the grip 12.

[0094] For example, the first switch 42 and the second switch 43 may be located on different sides of the grip portion 12 to facilitate the user's differentiation between the first switch 42 and the second switch 43, while preventing accidental activation. For instance, the second switch 43 may be located on the side where the second air vent 10c is located, and the first switch 42 may be located on the adjacent side.

[0095] For example, such as Figure 4 As shown, the air outlet 11 may include a first air outlet 111 of the first housing 101 and a second air outlet 112 of the second housing 102. The gripping part 12 includes a first gripping part 121 of the first housing 101 and a second gripping part 122 of the second body. The receiving cavity 10a includes a first cavity and a second cavity. The first air outlet 111 and the second air outlet 112 surround to form the first cavity. The first gripping part 121 and the second gripping part 122 surround the second cavity. The blowing assembly 20 may be disposed in the first cavity, and the energy storage assembly 30 may be disposed in the second cavity.

[0096] In some embodiments, the energy storage component 30 is disposed on the grip portion 12 to improve the space utilization of the housing 10, and at the same time to help balance the gravity of the air blower, making it convenient for the user to hold it stably.

[0097] Furthermore, the emergency interface 32 is located at one end of the grip 12 near the air outlet 11 and / or at the end of the grip 12 away from the air outlet 11. This prevents accidental contact with the emergency interface 32 when holding the grip 12 and using the air blower, while allowing the user to easily connect the emergency interface 32 to the vehicle while holding the grip 12 to maintain the stability of the air blower.

[0098] In some embodiments, the air guide 60 has an air guide channel 61, which is connected to the air outlet 20a of the blowing assembly 20, allowing the airflow output from the air outlet 20a to be blown out through the air guide channel 61. By introducing the airflow output from the air outlet 20a into the air guide channel, the airflow velocity or flow range can be adjusted within the air guide channel 61, preventing the airflow from being too dispersed and affecting the airflow effect.

[0099] like Figure 6 , Figure 8 and Figure 10 As shown, the flow guiding channel further includes a collecting section 611 and a guiding section 612. The collecting section 611 connects the second air outlet 10c and the guiding section 612. The radial dimension of the collecting section 611 gradually decreases along the direction from the collecting section 611 to the guiding section 612. It can be understood that the gradual decrease in the radial dimension of the collecting section 611 along the direction from the collecting section 611 to the guiding section 612 allows the airflow output from the air outlet 20a of the blowing assembly 20 to be concentrated in the collecting section 611 after entering the flow guiding channel, thereby increasing the wind speed and improving the air outlet efficiency.

[0100] For example, the direction from the collection section 611 to the guide section 612 can be as follows: Figure 3 The X direction is shown in the diagram.

[0101] Understandably, the radial dimensions of the guide section 612 can be designed according to the application scenario.

[0102] For example, such as Figure 5 and Figure 6 As shown, the radial dimension of the guide section 612 can gradually decrease along the direction from the collection section 611 to the guide section 612, so that the airflow output from the collection section 611 is further concentrated in the guide section 612, and the airflow velocity is further increased, which makes it easier for the airflow to penetrate into the gaps with small spacing for dust removal.

[0103] For example, such as Figures 7 to 10 As shown, the radial dimension of the guide section 612 can gradually increase along the direction from the collection section 611 to the guide section 612, so that the airflow output from the collection section 611 can be stably diffused in the guide section 612, increasing the air outlet area of ​​the air blower and facilitating the air outlet to remove dust or dry a large area.

[0104] For example, such as Figure 7 and Figure 8 As shown, there is also an extension section 613 between the collection section 611 and the guide section 612. The radial dimension of the extension section 613 is consistent in the direction from the collection section 611 to the guide section 612. This avoids the situation where the airflow cannot diffuse to the radial edge of the guide section 612 after being output from the collection section 611 due to the excessive difference in radial dimension between the collection section 611 and the guide section 612. In other words, it can prevent the guide section 612 from being unable to adjust the outlet area of ​​the airflow.

[0105] In some embodiments, the air guide 60 is detachably connected to the housing 10 or the blowing assembly 20. By replacing the air guide 60 with different structures, the air blower can have a variety of air output effects, thereby improving the adaptability of the air blower and enabling it to be used in more scenarios.

[0106] For example, such as Figure 11 and Figure 12 As shown, the blower assembly 20 is located in the receiving cavity 10a of the housing 10, and the guide member 60 is detachably connected to the housing 10 to facilitate the disassembly and assembly of the guide member 60 while protecting the blower assembly 20.

[0107] In some embodiments, the housing 10 is snapped onto the flow guide 60; and / or, the housing 10 and the flow guide 60 are magnetically connected; and / or, the housing 10 and the flow guide 60 are threaded together; and / or, the housing 10 and the flow guide 60 are interference-fitted. It is understood that the connection method between the housing 10 and the flow guide 60 is quite flexible and can be adjusted according to actual conditions.

[0108] For example, the flow guide 60 is sleeved on the outer periphery of the housing 10. The outer periphery of the housing 10 is provided with one of a locking block 6011 or a locking groove 1011, and the inner side of the flow guide 60 is provided with the other of a locking block 6011 or a locking groove 1011. The housing 10 and the flow guide 60 are locked together by the locking block 6011 engaging with the locking groove 1011.

[0109] For example, multiple snap-fit ​​connections are made between the flow guide 60 and the housing 10, which helps to improve the connection stability between the flow guide 60 and the housing 10.

[0110] In some embodiments, one of the housing 10 and the flow guide 60 is provided with a guide groove 601, and the other of the housing 10 and the flow guide 60 is provided with a protrusion 101. The protrusion 101 is movably engaged with the guide groove 601, and the protrusion 101 can move relative to the guide groove 601 until the housing 10 and the flow guide 60 are engaged. By movably engaging the protrusion 101 and the guide groove 601, the flow guide 60 is guided to move relative to the housing 10 in a predetermined direction, so as to facilitate engaging the flow guide 60 onto the housing 10. At the same time, the movable engagement of the protrusion 101 and the guide groove 601 helps to further improve the connection stability between the housing 10 and the flow guide 60.

[0111] For example, such as Figure 12 As shown, the outer periphery of the housing 10 is provided with a protrusion 101, and a slot 1011 is formed through the protrusion 101. The inner side of the flow guide 60 is provided with a guide groove 601, and a locking block 6011 is formed on the groove wall surface of the guide groove 601. After the protrusion 101 is inserted into the guide groove 601 from the groove opening, the flow guide 60 is controlled to rotate relative to the housing 10, so that the protrusion 101 slides along the groove wall of the guide groove 601 until the locking block 6011 is engaged with the slot 1011, thereby realizing the engagement of the flow guide 60 and the housing 10.

Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
