Description
Technical Field
[0001] This utility model relates to the field of vacuum cleaner technology, specifically to a portable vacuum cleaner. Background Technology
[0002] Vacuum cleaners, as a common indoor cleaning tool, are widely used in homes, offices, shopping malls, and industrial environments. Traditional vacuum cleaners typically use a motor-driven fan to create negative pressure, sucking dust, hair, paper scraps, etc., from the floor or object surface into a dust cup or dust bag, thus achieving the cleaning function. To adapt to different cleaning scenarios, vacuum cleaners are often equipped with various types of suction heads, such as floor brushes, crevice nozzles, and bristle brushes, to address the cleaning needs of different locations such as floors, carpets, corners, and furniture crevices. However, existing portable vacuum cleaners have significant shortcomings in terms of suction head replacement. Most products connect the suction head to the suction hose via clips, threads, or plugs. After long-term use, this connection method is prone to loosening or jamming due to wear of the clips or structural deformation. Users need to apply considerable force when replacing the suction head, and may even need tools, reducing replacement efficiency. Furthermore, some suction heads require complete disassembly of the entire suction hose or connectors during installation and removal, making the process cumbersome and increasing inconvenience for users in daily use.

Users need to apply considerable force when replacing the suction head, and may even need tools, reducing replacement efficiency. Furthermore, some suction heads require complete disassembly of the entire suction hose or connectors during installation and removal, making the process cumbersome and increasing inconvenience for users in daily use.
[0004] In view of the above, in order to overcome the above technical problems, this utility model designs a portable vacuum cleaner, which solves the above technical problems. Utility Model Content
[0005] The technical objective of this invention is to design a portable vacuum cleaner that improves replacement efficiency.
[0006] To achieve the above-mentioned technical objectives, this utility model provides the following technical solution: A portable vacuum cleaner includes a vacuum pump body, casters, a suction hose, a handheld handle, a working tube, an interception component, an adjustment component, and a suction component. The vacuum pump body is located in the main body of the vacuum cleaner and provides suction to draw in and collect dust and debris through the suction hose. The casters are mounted below the vacuum pump body and, through rolling contact with the ground, allow the entire device to move easily between different positions, facilitating operation over a large cleaning area. The suction hose is fixedly mounted on the side of the vacuum pump body and communicates with a negative pressure channel inside the pump body, transmitting the suction generated by the suction component to the vacuum pump body. The handheld handle is mounted at one end of the suction hose, providing a gripping and control position for the user; its length and structural design facilitate adjustment of the suction direction and angle. The working tube is mounted at the other end of the handheld handle and is detachable, allowing for quick replacement of different types of working tubes or suction components for different cleaning tasks. The interception component is located inside the working tube and performs preliminary filtration and impurity interception of the intake air, preventing larger particles from entering the vacuum pump body and damaging its internal mechanisms. The adjustment component is installed inside the interception component and can adjust the suction power or airflow direction as needed to adapt to different cleaning scenarios. The dust collection component is installed at the top of the working tube and comes into direct contact with the surface being cleaned. Through a reasonable structural design, the suction power is concentrated on the target area, thereby achieving efficient cleaning. This structural combination makes the device highly practical in terms of mobility, multifunctionality, and ease of maintenance.
[0007] The handheld handle includes mounting threads, a sealing ring, a sealing cavity, a safety ring, and a sealing strip. The mounting threads are located on the outer surface of the handheld handle and are used to connect with the corresponding threaded opening of the suction or working tube, ensuring a secure installation between the handheld handle and other components. The sealing ring is fitted onto the outside of the handheld handle, achieving a sealing effect at the connection point through a tight fit with the handheld handle and adjacent components. The sealing cavity is the gap area between the handheld handle and the sealing ring, used to accommodate the sealing strip and form a buffer space under pressure, thereby improving sealing performance. The safety ring is fitted onto the outside of the sealing ring, serving to fix the sealing ring's position and prevent it from loosening or falling off during use. The sealing strip is embedded inside the safety ring, working together with the sealing cavity and the sealing ring to effectively prevent air leakage, ensuring stable suction and high efficiency of the vacuum cleaner during operation.
[0008] The working tube has an axially oriented mounting groove inside, designed in a spiral shape to engage with matching threaded connectors or sealing components. This ensures smooth guidance during installation and effectively improves the strength and reliability of the connection. The spiral design not only facilitates quick assembly and disassembly but also disperses axial stress at the connection point, extending the component's lifespan. The top surface of the working tube is machined with a sealing groove, precisely sized and shaped to accommodate sealing rings, gaskets, or other sealing elements. This forms an effective sealing barrier when the working tube connects to other components, preventing gas or dust leakage and maintaining the vacuum cleaner's suction stability and cleaning efficiency during operation.
[0009] The interception assembly includes a fixed ring, an interception frame, a fixed block, a rotating groove, and a limiting groove. The fixed ring is tightly installed inside the working pipe, providing a stable mounting base for the interception assembly. The interception frame is installed inside the fixed ring and is designed to initially intercept larger impurities or particles in the intake airflow, preventing them from entering subsequent channels and causing blockages or damage. The fixed block is located in the middle area of the fixed ring, ensuring stable support for the interception frame and related components through precise positioning. The rotating groove is located on the upper surface of the fixed block and is used to install rotatable adjustment components, allowing for fine-tuning of the angle or position of the interception frame when necessary. The limiting groove is located beside the rotating groove and is designed with an arc shape with a 90° arc angle. It limits the maximum rotation range of the rotating components, thereby preventing excessive rotation that could lead to structural misalignment or damage, and ensuring the safety and reliability of the interception assembly during operation.
[0010] The adjustment assembly includes a rotating block, an adjustment frame, a rotating ring, and an adjustment knob. The rotating block is fixedly mounted above the interception assembly, serving as the core supporting component and providing a mechanical connection and rotation fulcrum. The adjustment frame is mounted on the side of the rotating block, supporting the rotating ring with a robust structural design and working in conjunction with the rotating block to achieve precise adjustment of airflow direction or interception position. The rotating ring is located at the outer edge of the adjustment frame, cooperating with it through a ring structure to ensure smoother adjustment and stable positioning at different angles. The adjustment knob is located above the rotating block, serving as the direct interface for user operation. Rotating or pressing the knob causes the rotating block and its connected adjustment frame and rotating ring to move synchronously, enabling rapid adjustment of suction power, airflow direction, or interception position, thus improving the vacuum cleaner's adaptability and ease of operation in different cleaning scenarios.
[0011] A mounting block and a limiting bolt are installed below the rotating block. The mounting block is located at the center of the rotating block and engages tightly with the intercepting component or other connecting parts through precise dimensional matching, providing stable connection and torque transmission. The structural design of the mounting block facilitates quick positioning during assembly or disassembly, reducing installation time and improving assembly efficiency. The limiting bolts are respectively located above and below the mounting block. By cooperating with the limiting grooves or matching holes, they control the maximum stroke of the rotating block, preventing excessive offset during rotation that could lead to structural misalignment or damage. To reduce assembly friction and wear during use, the tips of the limiting bolts are rounded. This rounded design not only reduces resistance during insertion, removal, or rotation but also prevents scratches on other parts due to sharp edges, thereby improving overall smoothness and durability, and extending the service life of the vacuum cleaner.
[0012] The adjustment knob has multiple mating grooves along its circumference on its side. These grooves are evenly spaced and arranged in a circular array, allowing for reliable engagement with corresponding limiting components or locking structures when the knob rotates. The mating grooves not only provide clear positioning, giving the adjustment knob a distinct feel for different positions, but also effectively prevent accidental rotation due to vibration or external forces during operation, ensuring the stability of the adjustment state. The shape and depth of the grooves are optimized to provide sufficient friction for easy rotation without compromising the knob's overall appearance and tactile comfort. This circumferential array arrangement allows users to achieve a smoother and more precise operating experience when adjusting the vacuum cleaner's suction power or airflow direction, while also improving the applicability and safety of the adjustment components in various cleaning environments.
[0013] The beneficial effects of this utility model are as follows: (1) This utility model, through the reasonable combination of vacuum pump body, moving wheels, detachable hand handle and working tube, enables the equipment to maintain strong suction while possessing good mobility and flexibility. Users can easily push the equipment to use in different places using the moving wheels, reducing the burden of transportation; the detachable working tube and the combination of various vacuuming components not only facilitate quick replacement of vacuum heads to meet different cleaning needs such as floors, carpets, and crevices, but also save time and manpower during replacement or maintenance. The design of the hand handle and sealing structure effectively prevents air leakage, ensures stable suction, improves cleaning efficiency, and extends the service life of the equipment.
[0014] (2) This utility model incorporates an interception component and an adjustment component in its internal structure. Through multi-stage filtration and an adjustable airflow structure, it effectively blocks large particles of impurities from entering the vacuum pump body, preventing blockage and internal damage, and extending the overall lifespan of the machine. The adjustment knob, combined with the circumferential array of grooves, allows users to freely adjust the suction power and airflow direction according to different cleaning tasks, and maintains a stable speed during use, preventing misadjustment due to vibration or external force. The overall structural design combines the advantages of easy disassembly and assembly, reliable sealing, and flexible adjustment, greatly improving the practicality and adaptability of the vacuum cleaner in both home and commercial environments.

Detailed Implementation
[0018] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0019] like Figure 1-6 As shown, a portable vacuum cleaner includes a vacuum pump body 1, casters 2, a suction pipe 3, a handheld handle 4, a working pipe 5, an interception component 6, an adjustment component 7, and a suction component 8. The vacuum pump body 1 is located in the main body of the vacuum cleaner and provides suction to draw in and collect dust and debris through the suction pipe 3. The casters 2 are installed below the vacuum pump body 1 and, through rolling contact with the ground, allow the entire device to move easily between different positions, facilitating operation by the user in a large cleaning area. The suction pipe 3 is fixedly installed on the side of the vacuum pump body 1 and communicates with the negative pressure channel inside the pump body, transmitting the suction generated by the suction component 8 to the vacuum pump body 1. The handheld handle 4 is installed at one end of the suction pipe 3, providing a gripping and control position for the user; its length and structural design facilitate adjustment of the suction direction and angle. The working pipe 5 is installed at the other end of the handheld handle 4 and is detachable, allowing for quick replacement of different types of working pipes 5 or suction components 8 for different cleaning tasks. The interception component 6, located inside the working tube 5, performs preliminary filtration and impurity interception of the intake air, preventing larger particles from entering the vacuum pump body 1 and damaging its internal mechanisms. The adjustment component 7, installed inside the interception component 6, allows for adjustment of suction power or airflow direction to suit different cleaning scenarios. The dust collection component 8, mounted at the top of the working tube 5, directly contacts the surface being cleaned. Its optimized structural design concentrates suction power on the target area, achieving efficient cleaning. This combination of structures makes the device highly practical in terms of mobility, multifunctionality, and ease of maintenance.
[0020] like Figure 3 As shown, the handheld handle 4 includes a mounting thread 41, a sealing ring 42, a sealing cavity 43, a safety ring 44, and a sealing strip 45. The mounting thread 41 is located on the outer surface of the handheld handle 4 and is used to connect with the corresponding threaded opening of the suction pipe 3 or the working pipe 5, ensuring a stable installation between the handheld handle 4 and other components. The sealing ring 42 is fitted onto the outside of the handheld handle 4, achieving a sealing effect at the connection point through a tight fit with the handheld handle 4 and adjacent components. The sealing cavity 43 is the gap area between the handheld handle 4 and the sealing ring 42, used to accommodate the sealing strip 45 and form a buffer space under pressure, thereby improving sealing performance. The safety ring 44 is fitted onto the outside of the sealing ring 42, serving to fix the position of the sealing ring 42 and prevent it from loosening or falling off during use. The sealing strip 45 is embedded inside the safety ring 44, working together with the sealing cavity 43 and the sealing ring 42 to effectively prevent air leakage, ensuring stable suction and high efficiency of the vacuum cleaner during operation.
[0021] like Figure 4 As shown, the working tube 5 has an axially oriented mounting groove 51 inside. This mounting groove 51 is designed in a spiral shape to engage with matching threaded connectors or sealing components, thus achieving a smooth guiding effect during installation and effectively improving the strength and reliability of the connection. The spiral structure not only facilitates quick assembly and disassembly but also disperses the axial stress on the connection point to a certain extent, extending the service life of the components. The top surface of the working tube 5 is machined with a sealing groove 52. The size and shape of the sealing groove 52 are precisely matched to accommodate sealing rings, gaskets, and other sealing elements, forming an effective sealing barrier when the working tube 5 is connected to other components. This prevents gas or dust leakage from the connection point, thereby maintaining the suction stability and cleaning efficiency of the vacuum cleaner during operation.
[0022] like Figure 5 As shown, the interception assembly 6 includes a fixing ring 61, an interception frame 62, a fixing block 63, a rotating groove 64, and a limiting groove 65. The fixing ring 61 is tightly installed inside the working pipe 5, providing a stable mounting base for the interception assembly 6. The interception frame 62 is installed inside the fixing ring 61, and its structure is designed to initially intercept larger impurities or particles in the intake airflow, preventing them from entering subsequent channels and causing blockages or damage. The fixing block 63 is located in the middle area of the fixing ring 61, ensuring stable support for the interception frame 62 and related components through precise positioning. The rotating groove 64 is formed on the upper surface of the fixing block 63, used to install a rotatable adjustment component, allowing the interception frame 62 to be finely adjusted in angle or position when necessary. The limiting groove 65 is located beside the rotating groove 64, and its shape is an arc structure with an arc angle of 90°, used to limit the maximum rotation range of the rotating component, thereby avoiding excessive rotation that could lead to structural misalignment or damage, ensuring the safety and reliability of the interception assembly 6 during operation.
[0023] like Figure 5-6As shown, the adjustment component 7 includes a rotating block 71, an adjustment frame 72, a rotating ring 73, and an adjustment knob 74. The rotating block 71 is fixedly installed above the interception component 6, serving as the core supporting component of the adjustment component 7, forming a mechanical connection with the interception component 6 and providing a rotation fulcrum. The adjustment frame 72 is installed on the side of the rotating block 71, supporting the rotating ring 73 through a stable structural design and working in conjunction with the rotating block 71 to achieve precise adjustment of the airflow direction or interception position. The rotating ring 73 is located at the outer edge of the adjustment frame 72, cooperating with the adjustment frame 72 through a ring structure, making the adjustment process smoother and maintaining stable positioning at different angles. The adjustment knob 74 is located above the rotating block 71, serving as the direct interface for user operation. Rotating or pressing the adjustment knob 74 causes the rotating block 71 and its connected adjustment frame 72 and rotating ring 73 to move synchronously, thereby achieving rapid adjustment of suction power, airflow direction, or interception position, improving the adaptability and ease of operation of the vacuum cleaner in different cleaning scenarios.
[0024] Below the rotating block 71, an mounting block 711 and a limiting bolt 712 are installed. The mounting block 711 is located at the center of the rotating block 71 and engages tightly with the intercepting component 6 or other connecting parts through precise dimensional fitting, providing stable connection and torque transmission. The structural design of the mounting block 711 facilitates quick positioning during assembly or disassembly, reducing installation time and improving assembly efficiency. The limiting bolts 712 are respectively located above and below the mounting block 711. Through engagement with the limiting groove 65 or matching holes, they control the maximum stroke of the rotating block 71, preventing excessive offset during rotation that could lead to structural misalignment or damage. To reduce assembly friction and wear, the top of the limiting bolt 712 is rounded. This rounded design not only reduces resistance during insertion, removal, or rotation but also prevents scratches on other parts due to sharp edges, thereby improving overall smoothness and durability, and extending the service life of the vacuum cleaner.
[0025] The adjustment knob 74 has multiple mating grooves 741 arranged circumferentially on its side. These grooves are evenly spaced and arranged in a circumferential array, allowing for reliable engagement with corresponding limiting components or snap-fit structures when the knob rotates. The mating grooves 741 not only provide clear positioning, giving the adjustment knob 74 a distinct feel for different positions, but also effectively prevent accidental rotation due to vibration or external forces during operation, ensuring the stability of the adjustment state. The shape and depth of the grooves are optimized to provide sufficient friction for easy rotation without compromising the knob's overall appearance and tactile comfort. This circumferential array arrangement allows users to achieve a smoother and more precise operating experience when adjusting the vacuum cleaner's suction power or airflow direction, while also improving the applicability and safety of the adjustment component 7 in different cleaning environments.
[0026] In the operation of this utility model, when it is necessary to replace the dust collection component 8, the working tube 5 is rotated to disengage the mounting groove 51 and the mounting thread 41, so that different dust collection components 8 can be freely replaced. After replacement, when the vacuum pump body 1 is in operation, at the connection between the handheld lever 4 and the working tube 5, the gas is intercepted by multiple deep groove structures to achieve a seal, ensuring the efficiency of vacuum dust collection. Staff can also use the adjustment component 7 to intercept large particles during vacuuming, depending on the usage scenario. Specifically, by adjusting the knob 74 to rotate the rotating block 71, the limit bolt 712 slides in the limit groove 65, and the adjustment frame 72 and the interception frame 62 form gaps of different sizes according to different angles, thereby controlling the radius of objects that can pass through.
[0027] Various modifications to this disclosure will be readily apparent to those skilled in the art, and the general principles defined herein can be applied to other variations without departing from the scope of this disclosure. Therefore, this disclosure is not limited to the examples and designs described herein, but should be given the broadest scope consistent with the principles and novel features disclosed herein. Although one or more exemplary embodiments of this disclosure have been described with reference to the accompanying drawings, those skilled in the art will understand that various changes in form and detail may be made therein without departing from the spirit and scope of this disclosure as defined by the appended claims.
