Description

Technical Field

[0001] This utility model relates to the field of handheld fan technology, and in particular to a high-speed turbine fan. Background Technology

[0002] A handheld fan is a small, portable electric fan, typically powered by batteries or USB. They are usually lightweight and easy to carry, helping people feel cool in hot weather. Handheld fans are very practical for outdoor activities, travel, office use, and home use.

[0003] For a specific example of an existing handheld fan, see Chinese Patent CN221322762U, which describes a multi-functional handheld fan capable of both blowing and suction. One end is an air inlet, and the other is an air outlet. The air inlet is detachably connected to a vacuum nozzle, and the air outlet is detachably connected to a blower nozzle for concentrating airflow. By using a ducted motor, both the air inlet and outlet of the fan can generate a large air volume. Utilizing both suction and blowing functions, this handheld fan can be used as a fan or a vacuum cleaner, switching between different uses according to the user's needs. It is also small in size, making it easy to hold and carry. However, current users prefer handheld fans of different shapes to meet their individual needs. Some custom-designed handheld fans are not convenient for switching between blowing and suction functions by rotating the entire fan. Therefore, existing handheld fans cannot meet current production demands.

[0004] To solve the above problems, it is necessary to provide a high-speed turbo fan. Utility Model Content

[0005] The purpose of this invention is to provide a high-speed turbine fan that can switch between blowing and suction functions without rotating the entire fan.

[0006] To achieve the above objectives, the high-speed turbine fan provided by this utility model includes a housing, an air intake and blowing assembly, and a power supply assembly for supplying power to the air intake and blowing assembly. The housing is a hollow housing structure with an air flow channel inside. The housing has a first air outlet and a second air outlet on both sides of the air flow channel. One side of the air intake and blowing assembly is a blowing outlet, and the other side is an exhaust outlet. The housing has a clearance hole corresponding to the air intake and blowing assembly. The air intake and blowing assembly is pivotally connected to the air flow channel of the housing and rotates relative to the housing through the clearance hole. The rotation of the air intake and blowing assembly causes the blowing outlet to align with the first air outlet or the exhaust outlet to align with the first air outlet.

[0007] Preferably, the air intake and blowing assembly is pivotally connected to the housing via a connecting assembly. The connecting assembly includes a first limiting boss, a second limiting boss, and a rotating shaft extending outward from the air intake and blowing assembly. The first limiting boss and the second limiting boss are arranged at intervals along the length direction of the rotating shaft. The housing is provided with a connecting platform, and the connecting platform has a rotating hole corresponding to the rotating shaft. The rotating shaft is rotatably disposed in the rotating hole. The first limiting boss and the second limiting boss are located on both sides of the connecting platform for limiting.

[0008] Specifically, the housing includes a left shell and a right shell, which are joined together to form a hollow housing structure. The left shell extends inward to form a left connecting edge, and the right shell extends inward to form a right connecting edge. The left connecting edge has a left arc edge, and the right connecting edge has a right arc edge. The left connecting edge and the right connecting edge are joined together to form the connecting platform, and the left arc edge and the right arc edge are joined together to form the rotating hole.

[0009] Specifically, the left connecting edge extends toward the bottom of the air intake and blowing assembly to form a left top edge, and the right connecting edge extends toward the bottom of the air intake and blowing assembly to form a right top edge.

[0010] Preferably, the air intake and blowing assembly includes a housing, a drive component, and an impeller. The drive component is built into the housing, and the impeller is mounted on the output end of the drive component and rotates under its drive. The two ends of the housing in the front-to-back direction form the air blowing port and the air extraction port. The air blowing end of the impeller is close to the air blowing port, and the air extraction end of the impeller is close to the air extraction port. The housing is pivotally connected to the housing, and a clearance hole is provided on both the left and right sides of the housing.

[0011] Preferably, the second air vent is equipped with a baffle structure.

[0012] Preferably, the power supply component is built into the housing and is electrically connected to the air intake and blower component.

[0013] Specifically, the power supply component is a storage battery, which is detachably connected to the housing. The storage battery is provided with a charging interface. When the storage battery is inserted into the housing, it contacts the circuit board inside the housing.

[0014] Preferably, the housing is in the shape of a toy gun, the horizontal gun body structure of the toy gun structure is provided with the air flow channel and the air intake and blowing assembly, the vertical gun handle structure of the toy gun structure is provided with the power supply assembly, and the bottom of the vertical gun handle structure of the toy gun structure is provided with an installation port for installing or removing the power supply assembly.

[0015] Preferably, both the air outlet and the air extraction outlet are provided with a limiting baffle structure.

[0016] Compared with the prior art, the high-speed turbine fan provided by this utility model uses a housing to cooperate with the air intake and blowing assembly. The housing has a hollow structure that forms an air flow channel inside. The housing has a first air inlet and a second air inlet on both sides of the air flow channel. One side of the air intake and blowing assembly is the blowing port, and the other side is the suction port. The housing has a clearance hole corresponding to the air intake and blowing assembly. The air intake and blowing assembly is pivotally connected to the air flow channel of the housing and rotates relative to the housing through the clearance hole. That is, the clearance hole allows the air intake and blowing assembly to switch between two modes, air intake and air blowing, inside the housing by rotation. In this way, the user can switch the mode of the air intake and blowing assembly without rotating the entire housing. For example, when it is necessary to blow air as a fan, the air intake and blowing assembly rotates so that the blowing port of the air intake and blowing assembly is aligned with the first air inlet. At this time, the suction port of the air intake and blowing assembly is aligned with the second air inlet. The airflow enters from the second air inlet, passes through the suction port and the blowing port in sequence, and finally flows out from the first air inlet, thereby achieving the purpose of blowing air as a fan. When the air blower is needed to function as a mini vacuum cleaner, the air intake and blower assembly rotates so that the air intake port of the air intake and blower assembly is aligned with the first air outlet. At this time, the air outlet of the air intake and blower assembly is aligned with the second air outlet. The airflow enters from the first air outlet, passes through the air intake port and the blower port in sequence, and finally flows out from the second air outlet, thereby achieving the purpose of air intake and dust collection.

[0024] To explain in detail the technical content, structural features, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0025] Please see Figures 1 to 7 The high-speed turbine fan of this invention includes a housing 1, an air intake and blowing assembly 2, and a power supply assembly 3. The power supply assembly 3 supplies power to the air intake and blowing assembly 2. The housing 1 is a hollow structure with an air flow channel 11 inside. The air flow channel 11 is a straight channel and mainly provides space for gas flow to the air intake and blowing assembly 2. The housing 1 has a first air outlet 11a and a second air outlet 11b on both sides of the air flow channel 11. The air intake and blowing assembly 2 blows air at one end and draws air at the other end when it is operated, thereby forming convection, so that one side of the air intake and blowing assembly 2 is the air outlet 21. On the other side of the air intake and blower assembly 2 is the air extraction port 22. The housing 1 is provided with a clearance hole 14 corresponding to the air intake and blower assembly 2. The air intake and blower assembly 2 is pivotally connected to the air flow channel 11 of the housing 1 and rotates relative to the housing 1 through the clearance hole 14. By rotating the air intake and blower assembly 2, the air outlet 21 is aligned with the first air outlet 11a or the air extraction port 22 is aligned with the first air outlet 11a. It can be understood that the air intake and blower assembly 2 needs rotation space to switch modes within the housing 1. The clearance hole 14 can provide clearance for the rotation of the air intake and blower assembly 2, thus avoiding interference between the housing 1 and the air intake and blower assembly 2. The housing 1 has a hollow shell structure that forms an airflow channel 11 inside. The housing 1 has a first air vent 11a and a second air vent 11b on both sides of the airflow channel 11. One side of the suction-blowing assembly 2 is a blowing port 21, and the other side is an exhaust port 22. The housing 1 has a clearance hole 14 corresponding to the suction-blowing assembly 2. The suction-blowing assembly 2 is pivotally connected to the airflow channel 11 of the housing 1 and rotates relative to the housing 1 through the clearance hole 14. That is, the clearance hole 14 allows the suction-blowing assembly 2 to form suction and exhaust within the housing 1 through rotation. The air blowing mode allows the user to switch between the two modes without rotating the entire housing 1. For example, when the air blowing component 2 is needed to function as a fan, it rotates so that the air outlet 21 is aligned with the first air outlet 11a, and the air intake 22 is aligned with the second air outlet 11b. The operation of the air blowing component 2 creates air convection, with the airflow entering from the second air outlet 11b, passing through the air intake 22 and the air outlet 21, and finally exiting from the first air outlet 11a (flow direction as shown). Figure 6(As shown by arrow A), thus achieving the purpose of a blower fan. When it is needed to act as a mini vacuum cleaner, the suction and blowing assembly rotates so that the air intake 22 of the suction and blowing assembly 2 is aligned with the first air outlet 11a. At this time, the air outlet 21 of the suction and blowing assembly 2 is aligned with the second air outlet 11b. The operation of the suction and blowing assembly 2 creates air convection. The airflow enters from the first air outlet 11a, passes through the air intake 22 and the air outlet 21 in sequence, and finally flows out from the second air outlet 11b (flow direction as shown). Figure 6 (As shown in the opposite direction of the middle arrow A), thus achieving the purpose of air extraction and dust collection. More specifically, as follows:

[0026] Please see Figures 3 to 5 The suction and blowing assembly 2 is pivotally connected to the housing 1 via the connecting assembly 4. The connecting assembly 4 includes a first limiting boss 41, a second limiting boss 42, and a rotating shaft 43 extending outward from the suction and blowing assembly 2. The first limiting boss 41 and the second limiting boss 42 are arranged at intervals along the length direction of the rotating shaft 43. The housing 1 is provided with a connecting platform 15. The connecting platform 15 is provided with a rotating hole 151 corresponding to the rotating shaft 43. The rotating shaft 43 is rotatably disposed in the rotating hole 151. The first limiting boss 41 and the second limiting boss 42 are located on the upper and lower sides of the connecting platform 15 to limit the movement and prevent the suction and blowing assembly 2 from coming off.

[0027] Please see Figures 6 to 7 The shell 1 includes a left shell 16 and a right shell 17. The left shell 16 and the right shell 17 are joined together to form a hollow shell structure. The left shell 16 extends inward to form a left connecting edge 161, and the right shell 17 extends inward to form a right connecting edge 171. The left connecting edge 161 has a left arc edge 162, and the right connecting edge 171 has a right arc edge 172. Both the left arc edge 162 and the right arc edge 172 are semi-circular arcs. The two are joined together to form a circular hole. The left connecting edge 161 and the right connecting edge 171 are joined together to form a connecting platform 15, and the left arc edge 162 and the right arc edge 172 are joined together to form a rotating hole 151. Specifically, the left connecting edge 161 extends towards the bottom of the air intake and blower assembly 2 to form the left top edge 18, and the right connecting edge 171 extends towards the bottom of the air intake and blower assembly 2 to form the right top edge 19. The left top edge 18 is set as two and symmetrically supported at the bottom of the outer shell 23 of the air intake and blower assembly 2, and the right top edge 19 is set as two and symmetrically supported at the bottom of the outer shell 23 of the air intake and blower assembly 2. It can be understood that the installation of the air intake and blower assembly 2 can be achieved by merging and splicing the left shell 16 and the right shell 17.

[0028] Please see Figures 1 to 7The suction and blowing assembly 2 includes a housing 23, a drive component 24, and an impeller 26. The drive component 24 is built into the housing 23. The impeller 26 is mounted on the output end of the drive component 24 and rotates under its drive. The housing 23 forms a blowing port 21 and a suction port 22 at its two ends in the front-rear direction. The blowing end of the impeller 26 is close to the blowing port 21, and the suction end of the impeller 26 is close to the suction port 22. The housing 23 is pivotally connected to the housing 1. A clearance hole 14 is provided on both the left and right sides of the housing 23. Preferably, both the blowing port 21 and the suction port 22 are provided with a limiting baffle structure 25 to prevent the impeller 26 from being accidentally damaged. Of course, the manufacturer can adjust it according to actual needs, so it is not limited to this.

[0029] Please see Figures 4 to 5 The second air vent 11b is equipped with a baffle structure 12. The power supply component 3 is built into the housing 1 and is electrically connected to the air intake and exhaust component 2. For example, the power supply component 3 is a battery, which is detachably connected to the housing 1. The battery is provided with a charging interface. When the battery is inserted into the housing 1, it contacts the circuit board inside the housing 1, thereby achieving a power supply connection. When the battery is removed from the housing 1, the power supply is disconnected.

[0030] Please see Figures 1 to 5 In this embodiment, the housing 1 is shaped like a toy gun. The horizontal gun body structure of the toy gun structure is provided with an air flow channel 11 and an air suction and blowing component 2. The vertical gun handle structure of the toy gun structure is provided with a power supply component 3. The bottom of the vertical gun handle structure of the toy gun structure is provided with an installation port 13 for installing or removing the power supply component 3. The user can blow air and vacuum by holding the toy gun handle.

[0031] Please refer to the following: Figures 1 to 7 The working process of the high-speed turbine fan 100 of this utility model is as follows:

[0032] The battery is inserted into the housing 1, and the battery contacts the circuit board inside the housing 1 to achieve power supply connection. The hand-held button 5 of the toy gun turns on the suction and blowing assembly 2 by pressing it. When it is needed to blow air as a fan, the suction and blowing assembly 2 rotates so that the air outlet 21 of the suction and blowing assembly 2 is aligned with the first air outlet 11a. At this time, the air intake 22 of the suction and blowing assembly 2 is aligned with the second air outlet 11b. The operation of the suction and blowing assembly 2 forms the convection of air. The airflow enters from the second air outlet 11b, passes through the air intake 22 and the air outlet 21 in sequence, and finally flows out from the first air outlet 11a, thereby achieving the purpose of blowing air as a fan. When the air blower is needed to function as a mini vacuum cleaner, the suction and blowing assembly 2 rotates so that the air intake 22 of the suction and blowing assembly 2 is aligned with the first air outlet 11a. At this time, the air outlet 21 of the suction and blowing assembly 2 is aligned with the second air outlet 11b. The operation of the suction and blowing assembly 2 creates air convection. The airflow enters from the first air outlet 11a, passes through the air intake 22 and the air outlet 21 in sequence, and finally flows out from the second air outlet 11b, thereby achieving the purpose of suction and dust removal.

[0033] Compared with the prior art, the high-speed turbine fan provided by this utility model uses a housing 1 to cooperate with the air intake and blowing assembly 2. The housing 1 forms an airflow channel 11 inside through its hollow structure. The housing 1 has a first air outlet 11a and a second air outlet 11b on both sides of the airflow channel 11. One side of the air intake and blowing assembly 2 is a blowing port 21, and the other side is an air extraction port 22. The housing 1 is provided with a clearance hole 14 corresponding to the air intake and blowing assembly 2. The air intake and blowing assembly 2 is pivotally connected to the airflow channel 11 of the housing 1 and rotates relative to the housing 1 through the clearance hole 14. That is, the clearance hole 14 allows the air intake and blowing assembly 2 to rotate relative to the housing 1. The suction and blowing assembly 2 can switch between suction and blowing modes inside the housing 1 by rotation. This allows the user to switch modes of the suction and blowing assembly 2 without rotating the entire housing 1. For example, when it is needed to blow air as a fan, the suction and blowing assembly 2 is rotated so that the air outlet 21 of the suction and blowing assembly 2 is aligned with the first air outlet 11a. At this time, the air intake 22 of the suction and blowing assembly 2 is aligned with the second air outlet 11b. The airflow enters from the second air outlet 11b, passes through the air intake 22 and the air outlet 21 in sequence, and finally flows out from the first air outlet 11a, thereby achieving the purpose of blowing air as a fan. When the air blower is needed to function as a mini vacuum cleaner, the air intake 22 of the air intake 2 is rotated so that it is aligned with the first air outlet 11a. At this time, the air outlet 21 of the air intake 2 is aligned with the second air outlet 11b. The airflow enters from the first air outlet 11a, passes through the air intake 22 and the air outlet 21 in sequence, and finally flows out from the second air outlet 11b, thereby achieving the purpose of air intake and dust collection.

[0034] The above-disclosed examples are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
