Description

Technical Field

[0001] The present invention relates to the technical field of mobile power supplies, and in particular to a mobile power supply with a dust cleaning function. Background Art

[0002] Power banks (also known as portable chargers) have become an indispensable electronic device in modern life. With frequent use and portability, their interfaces (such as USB and Type-C) are prone to accumulating dust, dirt, and other impurities. These impurities not only affect the aesthetics of the interfaces but, more importantly, can lead to poor contact, reduced charging efficiency, and even device damage.

[0003] Power banks currently on the market typically use the following methods to address dust accumulation in their ports: Users must regularly manually clean the ports with a brush or compressed air can. While this method is simple and straightforward, it's inconvenient and difficult to thoroughly clean. Some power banks also feature removable dust plugs on the ports. While this method can prevent dust from entering to a certain extent, the plugs are easily lost, and dust accumulation is still difficult to prevent during frequent plugging and unplugging. Summary of the Invention

[0004] In order to overcome the technical problems described in the background art, the present invention provides a mobile power supply with a dust cleaning function.

[0006] Furthermore, it also includes a dust-blocking blocking net, which is fixed to a side of the fixed tube close to the fan blades.

[0007] Furthermore, a truncated cone-shaped air gathering port is opened inside the inlet of the fixed cylinder close to the first guide cavity, and the opening of the air gathering port close to the first guide cavity is smaller than the opening away from the first guide cavity.

[0008] Furthermore, a plurality of partitions for refocusing wind are evenly arranged in the first guide cavity of the rotating frame.

[0009] Furthermore, the device further comprises a motor, which is fixed in the upper housing, and a reducer is provided between the output shaft of the motor and the rotating frame.

[0010] Furthermore, the reducer is composed of a large gear and a small gear, the large gear is fixedly connected to the rotating frame, and the small gear is fixedly connected to the output shaft of the motor.

[0011] Furthermore, a plurality of ventilation holes are provided on a side of the fixing tube close to the barrier net.

[0012] Furthermore, a dust cover is included for covering the interface. The dust cover is made of a soft material and is fixed to a side of the lower shell close to the interface.

[0013] Furthermore, it also includes a push rod, which is slidably connected to the side of the upper shell near the interface. When the dust cover is covered, the dust cover contacts the push rod. A channel communicating with the diverter rack is opened on the side of the upper shell near the push rod. A rotating plate is rotatably connected to the side of the channel of the upper shell near the fixed cylinder. The push rod is movably connected to the rotating plate through a movable hole, and a torsion spring is fixed between the rotating plate and the diverter rack.

[0014] Furthermore, it also includes pushing teeth distributed at equal intervals, the pushing teeth are fixed to the side of the large gear of the reducer close to the small gear, the side of the diverter frame close to the fixed cylinder is slidably connected to a connecting rod, the pushing teeth rotate and contact the end of the connecting rod, a spring is fixed between the connecting rod and the diverter frame, the side of the diverter frame close to the USB interface is rotatably connected to a baffle distributed at equal intervals, the connecting rod has a movable hole corresponding to the baffle, and the connecting rod is movably connected to the corresponding baffle through the movable hole.

[0015] The beneficial effects of the present invention are as follows: the present invention utilizes the first flow guide cavity and the wind guide cavity to form an air guide channel for cleaning the USB interface, utilizes the second flow guide cavity and the wind guide cavity to form an air guide channel for cleaning the Type-C interface, and utilizes the rotating frame to rotate and switch the two air guide channels, thereby realizing the function of alternating cleaning of the interface, and can reduce the loss of wind energy, ensure the wind force for cleaning, and thus improve the cleaning effect.

[0016] The present invention provides ventilation holes so that when the interface is blown to clean dust, the hot air generated by the internal operation of the mobile power supply enters the low-pressure fixed cylinder through the ventilation holes, and flows to the interface with the wind and is discharged into the external environment. During the period when the air guide cavity is rotated to cover the air, the external cold air enters the power supply through the ventilation holes, or by covering the dust cover, the cold air in the diversion frame flows into the mobile power supply through the channel above the rotating plate. In this way, heat dissipation is achieved through multiple ways, thereby enhancing the heat dissipation effect of the mobile power supply.

[0017] In the early stage, the present invention continuously blows a stable airflow to the USB interface, which can quickly blow away light dust on the surface of and near the power interface. In the later stage, intermittent air is blown to the USB interface, and a larger impact force is formed at the initial startup stage of each blowing, which is more conducive to loosening and removing stubborn dust. Through multiple impacts, the dust hidden deep inside the USB interface can be gradually blown out, and the dust cleaning is more thorough. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example 1: A mobile power supply with dust cleaning function, such as Figures 1-6 As shown, it includes an upper shell 101, and the lower side of the upper shell 101 is snap-connected to the lower shell 102. Two types of interfaces 1021, Type-C and USB, are provided on the left side of the upper shell 101. A plurality of vents 1022 are provided on the side of the interface 1021. A fixed cylinder 103 is fixedly connected to the left inner part of the upper shell 101. A truncated cone-shaped air gathering port is provided on the front inner side of the fixed cylinder 103, and the opening on the rear side of the air gathering port is smaller than the opening on the front side. A rotating frame 104 is rotatably connected to the fixed cylinder 103. A motor 105 is fixedly connected to the rear inner part of the upper shell 101. The output shaft of the motor 105 is rotatably connected to the rotating frame 104, and the output shaft of the motor 105 penetrates forward into the fixed cylinder 103. The output shaft of the motor 105 is fixedly connected to the fan blade 106. The fan blade 106 is located on the inner front side of the fixed cylinder 103. The fan blade 106 is used to move the outer Part of the air is sucked into the fixed cylinder 103, and a dust-blocking blocking net 107 is fixed to the front side of the fixed cylinder 103 to prevent dust from entering the fixed cylinder 103. The side of the fixed cylinder 103 near the interface 1021 is connected to a diverter frame 108, and an air guide cavity 109 is opened in the diverter frame 108. The air guide cavity 109 is communicated with the vent 1022 and is used to guide the wind diversion to each interface 1021. The rotating frame 104 is provided with a first guide cavity 110 and a second guide cavity 111 which are communicated with the air collecting port of the fixed cylinder 103. The rotation of the rotating frame 104 drives the first guide cavity 110 and the second guide cavity 111 to rotate alternately until they are aligned with the air guide cavity 109. A plurality of partitions are evenly arranged in the first guide cavity 110 of the rotating frame 104. The two partitions near the air collecting port of the fixed cylinder 103 can gather the incoming windflow to prevent the diffusion loss of wind energy.

[0033] like Figure 7 As shown, it also includes a motor 201, which is fixed to the rear part of the upper shell 101. The motor 201 is located on the right side of the motor 105. A reducer 202 is arranged between the output shaft of the motor 201 and the rotating frame 104. The reducer 202 is composed of a large gear and a small gear. The large gear is fixed to the rotating frame 104, and the small gear is fixed to the output shaft of the motor 201.

[0034] When the interface 1021 needs to be cleaned, the motor 105 and the motor 201 are started, and the output shaft of the motor 105 drives the fan blades 106 to rotate at a high speed, so that the external air forms a wind flow, and the wind flow entering from the wind gathering port of the fixed cylinder 103 flows through the first guide cavity 110 to the front of the wind guide cavity 109 of the diversion frame 108, and guides the wind to the two USB interfaces 1021 on the front side. At the same time, the output shaft of the motor 201 drives the rotating frame 104 to rotate slowly through the reducer 202. When the rotating frame 104 rotates to the intersection of the second guide cavity 111 and the wind guide cavity 109, the wind flow is turned to the left and right sides of the second guide cavity 111. When the rear part is aligned, the first guide cavity 110 is misaligned with the front part of the wind guide cavity 109. At this time, the wind flow entering from the air gathering port of the fixed cylinder 103 flows through the second guide cavity 111 to the rear part of the wind guide cavity 109 of the diverter rack 108, and directs the wind to the Type-C interface 1021 on the rear side. In this way, the interface 1021 realizes the function of alternating cleaning. Compared with the method of cleaning all interfaces 1021 at the same time, alternating cleaning can reduce the loss of wind energy, ensure the wind force for cleaning, and thus improve the cleaning effect. After cleaning for a period of time, turn off the motor 105 and the motor 201.

[0035] Example 2: Based on Example 1, Figure 4 and Figure 8 As shown, a plurality of ventilation holes 301 are opened on the front side of the fixing cylinder 103 .

[0036] Due to the action of the fan blades 106, the internal air flow rate of the diverter frame 108 near the fan blades 106 is faster. According to the Bernoulli principle, the air pressure in the area with fast flow rate is lower. Therefore, the hot air generated by the internal operation of the mobile power supply enters the low-pressure fixed cylinder 103 through the ventilation holes 301, and flows with the wind to the interface 1021 and is discharged to the external environment, thus achieving a heat dissipation effect.

[0037] During the rotation and switching process of the rotating frame 104, there is an interval in which the air guide cavity 109 is blocked. During this period, the air guide cavity 109 is neither aligned with the first guide cavity 110 nor with the second guide cavity 111, resulting in the airflow being unable to be discharged through the interface 1021. The interior of the fixed cylinder 103 close to the fan blade 106 becomes a high-pressure area, so the external cold air can only be discharged into the mobile power supply through the ventilation hole 301, thereby achieving a heat dissipation effect.

[0038] like Figures 8-10As shown, it also includes a dust cover 401 for blocking the interface 1021. The dust cover 401 is set to a soft material. The dust cover 401 is fixed to the left side of the lower shell 102. The left side of the upper shell 101 is connected to a push rod 402 for sliding along the left and right directions. When the dust cover 401 is covered, the dust cover 401 contacts the push rod 402 and squeezes the push rod 402 to slide to the right. A channel communicating with the diverter rack 108 is opened on the side of the upper shell 101 close to the push rod 402. A rotating plate 403 is rotatably connected to the side of the fixed cylinder 103 in the channel of the upper shell 101. The rotating plate 403 is rotatably connected to the diverter rack 108. The right end of the push rod 402 is movably connected to the rotating plate 403 through a movable hole. A torsion spring 404 is fixed between the front side of the rotating plate 403 and the diverter rack 108.

[0039] Since the ventilation hole 301 is small, the efficiency of inputting cold air into the mobile power supply through the ventilation hole 301 is low. Therefore, when the mobile power supply is seriously heated, the dust cover 401 can be covered while the fan blades 106 are blowing. The dust cover 401 pushes the push rod 402 to slide to the right, and the push rod 402 pushes the rotating plate 403 to rotate downward and open through the movable hole. The torsion spring 404 is deformed, so that the cold air in the diverter rack 108 flows into the mobile power supply through the channel above the rotating plate 403, thereby enhancing the heat dissipation effect. When the dust cover 401 is opened, the torsion spring 404 resets and drives the rotating plate 403 to rotate upward and close. The rotating plate 403 pushes the push rod 402 to slide to the left and reset through the movable hole.

[0040] Example 3: Based on Example 2, Figure 11 and Figure 12 As shown, it also includes pushing teeth 501 distributed at equal intervals, and one side of the pushing tooth 501 is set as a wedge-shaped surface. The pushing tooth 501 is fixed to the side of the large gear of the reducer 202 close to the small gear. The front right side of the diverter frame 108 is connected with a connecting rod 502 for sliding along the front and rear directions. When the pushing tooth 501 rotates counterclockwise, its wedge-shaped surface contacts the rear end of the connecting rod 502. A spring 503 is fixed between the connecting rod 502 and the diverter frame 108. The side of the diverter frame 108 close to the USB interface 1021 is rotatably connected with a baffle 504 distributed at equal intervals. The connecting rod 502 has a movable hole corresponding to the baffle 504, and the connecting rod 502 is movably connected to the corresponding baffle 504 through the movable hole.

[0041] During the process of the rotating frame 104 rotating from the first guide cavity 110 and the air guide cavity 109 to the second guide cavity 111 and the air guide cavity 109, in the early stage, the connection between the first guide cavity 110 and the front of the air guide cavity 109 is opened. At this time, the airflow continues to flow to the front of the air guide cavity 109 through the first guide cavity 110. In this way, the present invention can quickly blow away the light dust on and near the surface of the power interface 1021 by continuously blowing out a stable airflow to the USB interface 1021 in the early stage.

[0042] When blowing continuously, dust may form a relatively stable "wind resistance" under the action of wind, making it difficult to completely remove some dust. Therefore, in the later stage, the large gear of the reducer 202 drives the pushing tooth 501 to rotate to the wedge surface and intermittently contact the connecting rod 502, thereby pushing the connecting rod 502 to slide back and forth intermittently, and the spring 503 is intermittently compressed and reset. When the connecting rod 502 slides forward, the baffle 504 is pushed to rotate and close through the movable hole thereon. When the connecting rod 502 slides backward, the baffle 504 is pulled to reverse and open through the movable hole thereon. During this period, the airflow intermittently flows to the front of the air guide cavity 109 through the first guide cavity 110. In this way, the present invention later blows intermittent air to the USB interface 1021, and forms a larger impact force at the beginning of each blowing, which is more conducive to loosening and removing stubborn dust. Through multiple impacts, the dust hidden deep inside the USB interface 1021 can be gradually blown out, and the dust cleaning is more thorough.

[0043] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
