Description

Technical Field

[0001] This invention relates to the field of cleaning tools, and in particular to a handheld vacuum cleaner. Background Technology

[0002] Handheld vacuum cleaners are mainly used for quickly cleaning dust, debris, hair and other dirt in small areas such as desktops, sofas, beds, car interiors and furniture crevices. They have the advantages of small size, easy access, flexible operation and suitability for on-the-go cleaning, so they are widely used in household cleaning, car cleaning and spot cleaning scenarios.

[0003] Current handheld vacuum cleaners typically consist of a main body housing, and within that housing, a motor / fan assembly, a dust collection assembly, and a battery assembly. The front of the main body housing usually features a dust cup cover or suction inlet. To facilitate one-handed operation, existing products typically include a handle on the main body housing, with the grip direction generally aligned with the extension direction of the dust cup cover or suction inlet. To improve visibility when cleaning in low light, some handheld vacuum cleaners also include auxiliary lighting. These lights are usually located on the top front of the main body housing, or at the rear or tail of the vertical handle, to provide auxiliary illumination of the area in front during use. However, since these lighting components are often located on the top, front, or rear of the vacuum cleaner main body, when the dust cup cover is connected to the main body via an extension tube, suction tube, or connecting tube, there is often a significant distance between the suction inlet where cleaning is performed and the light source, making it difficult for the light to directly and accurately illuminate the actual cleaning area. Especially in areas with many obstructions, such as crevices, corners, and under furniture, insufficient lighting still exists near the suction port, affecting the user's observation of dust locations and the overall cleaning effect. Secondly, in most existing handheld vacuum cleaners, the vertical handle is held along the same axis as the cleaning head or the extension direction of the vacuum cleaner body. When vacuuming surfaces such as desktops, floor corners, soft cushions, and car floor mats, users often need to continuously deflect or twist their wrists to forcefully adjust the cleaning head to align with the surface to be cleaned. This not only results in an unnatural grip and strenuous operation, but also easily causes hand and wrist fatigue during prolonged use, leading to poor comfort and hindering precise cleaning of complex angles and confined spaces.

[0004] Therefore, in order to solve the above-mentioned technical problems, it is urgent to develop a handheld vacuum cleaner that is easy to hold and can directly irradiate the area to be vacuumed with the shortest path. Summary of the Invention

[0005] The present invention provides a handheld vacuum cleaner to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, in a first aspect, the present invention provides a handheld vacuum cleaner, comprising:

The conical-cylindrical surfaces that are tangent to each other have a common intersection point. The distance from this intersection point to the lighting component is the minimum shadowless distance, so as to achieve grayscale shadowless lighting for the area to be vacuumed that is farther away than the minimum shadowless distance.

[0059] The handheld vacuum cleaner proposed in this invention has the following beneficial effects:

[0060] The handheld vacuum cleaner proposed in this invention includes a main unit and a dust cup assembly. The main unit has a built-in power supply and includes a horizontal cylindrical section. The dust cup assembly includes a dust cup cylinder and a dust cup cylinder front cover. One end of the dust cup cylinder is engaged with one end of the horizontal cylindrical section, and the other end of the dust cup cylinder is hinged to one end of the dust cup cylinder front cover. The end face of the dust cup cylinder front cover facing the area to be vacuumed is provided with an illumination component. A conductive device is provided on the dust cup cylinder to electrically connect the built-in power supply to the illumination component. When the dust cup cylinder is separated from the horizontal cylindrical section and / or from the dust cup cylinder front cover, the conductive device automatically disconnects the electrical connection between the built-in power supply and the illumination component. The dust cup assembly in this application includes a dust cup cylinder front cover and a dust cup cylinder front cover design that can be rotated and engaged / disengaged. The design of one end of the dust cup cylinder engaging with one end of the horizontal cylinder greatly facilitates the user's process. Users no longer need to laboriously rotate the dust cup assembly from the horizontal cylinder end of the main unit to release the engagement; a simple press on the engagement device releases the dust cup cylinder front cover from the dust cup cylinder. The dust cup cylinder front cover automatically rotates open using its own gravity, allowing the dust cup cylinder to be easily tilted to empty the dust, debris, hair, and other contaminants contained in the dust collection chamber J within the dust cup assembly. This convenient and quick method enhances the user experience. A conductive device is provided on the dust cup cylinder to connect the built-in power supply to the lighting component. When the dust cup cylinder is separated from the horizontal cylinder and / or from the dust cup cylinder front cover, the conductive device automatically disconnects the built-in power supply from the lighting component.

[0061] In this application, a ring-shaped lighting component surrounding the suction port is mounted on the front cover of the dust cup, positioned close to the suction port. This ensures that the light emission position of the ring-shaped lighting component is close to the suction position. The ring-shaped lighting component contains at least two LEDs surrounding the suction port. These LEDs share a common focal point on the axis of the suction port, formed by a straight line tangent to the outer edge of the suction port and the light emission points of the multiple LEDs. This achieves "shadowless illumination" of the area outside this focal point. The multiple LEDs of the ring-shaped lighting component are arranged circumferentially around the suction port, allowing the light emitted by the LEDs to illuminate the area in front of the suction port. Because the multiple LEDs are arranged circumferentially around the axis of the suction port, the light emitted by the LEDs forms a uniform illumination range around the area in front of the suction port, thus illuminating the front of the suction port and the surrounding area to be cleaned. By mounting the ring-shaped lighting component on the front cover of the dust cup and positioning it close to the suction port, the distance between the lighting component and the actual suction position is shortened.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0086] The ring light assembly on existing vacuum cleaners is usually located on the top, front, or rear of the vertical handle. When the dust cup front cover is connected to the main unit via an extension tube, suction tube, or connecting tube, there is often a considerable distance between the actual suction inlet and the light source. This makes it difficult for the light to directly and accurately illuminate the actual dust location. Especially in areas with many obstructions, such as crevices, corners, and under furniture, insufficient lighting still exists near the suction inlet, affecting the user's observation of dust locations and the overall cleaning effect.

[0087] Based on this, the first aspect, such as Figures 1-8As shown, the present invention provides a handheld vacuum cleaner, which includes a main unit 1 and a dust cup assembly 3. The main unit 1 is equipped with a built-in power supply (not shown in the figure). The main unit 1 includes a horizontal cylindrical part 10a, and a high-pressure blower 10A is built into the horizontal cylindrical part 10a. The dust cup assembly 3 includes a dust cup cylinder 30a and a dust cup cylinder front cover 30b. One end of the dust cup cylinder 30a is engaged with one end of the horizontal cylindrical part 10a, and the other end of the dust cup cylinder 30a is hinged to one end of the dust cup cylinder front cover 30b. The end face of the dust cup cylinder front cover 30b facing the area to be vacuumed is provided with a lighting component 30b6. A conductive device is provided on the dust cup cylinder 30a to electrically connect the built-in power supply to the lighting component 30b6. When the dust cup cylinder 30a is separated from the horizontal cylindrical part 10a and / or from the dust cup cylinder front cover 30b, the conductive device automatically disconnects the electrical connection between the built-in power supply and the lighting component 30b6.

[0088] With this design, the dust cup assembly 3 includes a dust cup cylinder front cover 30b and a dust cup cylinder front cover 30b that can be rotated and engaged / disengaged. The design of one end of the dust cup cylinder 30a engaging with one end of the horizontal cylinder 10a greatly facilitates the user's decision not to laboriously rotate the dust cup assembly 3 away from the horizontal cylinder 10a of the main unit. Simply pressing lightly on the engaging device will release the dust cup cylinder front cover 30b from the dust cup cylinder 30a. The dust cup cylinder front cover 30b can automatically rotate and open using its own gravity. The dust cup cylinder 30a can be easily tilted to empty the dust, debris, hair, and other dirt contained in the dust storage chamber J of the dust cup assembly 3. This is convenient, quick, and improves the user experience. The dust cup 30a is equipped with a conductive device that can connect the built-in power supply to the lighting component 30b6. When the dust cup 30a is separated from the horizontal cylinder 10a and / or the dust cup 30a is separated from the dust cup front cover 30b, the conductive device automatically disconnects the built-in power supply from the lighting component 30b6.

[0089] In one or more alternative embodiments, such as Figures 1-6 , Figure 8 As shown, one end of the dust cup cylinder 30a is hinged to the front cover 30b of the dust cup cylinder, and one end of the front cover 30b of the dust cup cylinder can be rotatably fastened to one end of the dust cup cylinder 30a. The front cover 30b of the dust cup cylinder includes a front cover body 30b1. The lighting assembly 30b6 includes a lamp plate 30b61 and a lamp plate bracket 30b62. The lamp plate 30b61 is annular, and at least three LED beads are evenly distributed on the lamp plate 30b61. The point light source is the LED beads. The lamp plate bracket 30b62 is detachably connected to the front cover body 30b1. The lamp plate bracket 30b62 can install the lamp plate 30b61 and a power-taking spring pin 30b4 that is electrically connected to the lamp plate 30b61 and draws power outward. The power-taking spring pin 30b4 can be electrically connected to the dust cup cylinder 30a.

[0090] In one or more alternative embodiments, such as Figure 1-5 , Figures 7-8As shown, the main unit 1 also includes a vertical handle part 10b that is perpendicular to the horizontal cylinder part 10a. The vertical handle part 10b is equipped with a built-in power supply. At least two power supply spring pins 10a4 are provided at one end of the horizontal cylinder part 10a. The power supply spring pins 10a4 can lead out the output end of the built-in power supply to power the dust cup cylinder 30a, and then power the lamp board 30b61.

[0091] In one or more alternative embodiments, such as Figure 6 , Figure 8 As shown, the dust cup 30a includes a dust cup body 30a1. The conductive device consists of at least two power springs (positive power spring P and negative power spring Q) disposed at the bottom of the dust cup body 30a1. One end of the power spring is electrically connected to a power supply spring pin on one end face of the dust cup body 30a1, and the other end of the power spring is electrically connected to a power take-off spring pin on the other end face of the dust cup body 30a1. When the front cover of the dust cup is unfastened to the dust cup, the power spring is disconnected from the power take-off spring pin. When the dust cup is unfastened to the horizontal cylinder, the power spring is disconnected from the power supply spring pin.

[0092] This design enables power supply through physical contact between the power spring and the spring pin, and automatically disconnects the circuit when either component is separated, preventing live operation and avoiding short circuits.

[0093] In one or more alternative embodiments, the horizontal cylinder 10a houses a high-pressure blower 10A, and the vertical handle 10b has a built-in power supply that powers the high-pressure blower 10A.

[0094] In one or more alternative embodiments, the dust cup 30a can be rotated along its axis to engage with one end of the horizontal cylinder 10a. One end of the dust cup 30a is hinged to the front cover 30b of the dust cup 30a, and one end of the front cover 30b of the dust cup 30a can be rotated to engage with one end of the dust cup 30a. The other end of the front cover 30b of the dust cup 30a has a suction port 30b9. On the end face of the front cover 30b of the dust cup 30a and the suction port 30b9 on the same side, a ring-shaped lighting component 30b6 is provided around the axis of the suction port 30b9 in a circumferential direction near the suction port 30b9. The lighting component 30b6 is ring-shaped, and at least three point light sources are evenly distributed inside the lighting component 30b6. At least two power springs are provided on the dust cup 30a, at least two power supply springs 10a4 are provided on one end of the horizontal cylinder 10a, and power take-off springs 30b4 are installed on the lamp board bracket 30b62. The three work together to connect the built-in power supply to the lighting component 30b6.

[0095] In one or more alternative embodiments, the light emitted by the lighting component 30b6 around the dust extraction port 30b9 and the straight line tangent to the outer edge of the dust extraction port 30b9 have a common intersection point. The distance from the intersection point to the lighting component 30b6 is the shadowless projection distance, so as to achieve shadowless illumination of the area to be vacuumed that is farther away than the shadowless projection distance.

[0096] In one or more optional embodiments, the lighting assembly has at least three point light sources evenly distributed within it. The light rays emitted by the at least three point light sources around the dust extraction port 30b9 and the straight lines tangent to the outer edge of the dust extraction port 30b9 have a common intersection point. The distance from the intersection point to the lighting assembly 30b6 is the shadowless projection distance, so as to achieve shadowless lighting for the dust extraction area to be vacuumed at a distance greater than the shadowless projection distance.

[0097] In one or more optional embodiments, the lighting component 30b6 further includes a point light source conversion device that can convert at least three point light sources into annular surface light sources; the innermost circle of the annular surface light source with the smallest diameter has a common intersection point with the conical-annular cylindrical surface tangent to the outer edge of the suction port 30b9, and the distance from this intersection point to the lighting component 30b6 is the maximum shadowless distance, so as to achieve shadowless illumination of the area to be vacuumed where the distance is greater than the maximum shadowless distance; the outermost circle of the annular surface light source with the largest diameter has a common intersection point with the conical-annular cylindrical surface tangent to the outer edge of the suction port 30b9, and the distance from this intersection point to the lighting component 30b6 is the minimum shadowless distance, so as to achieve grayscale shadowless illumination of the area to be vacuumed where the distance is greater than the minimum shadowless distance; when the distance between the lighting component 30b6 and the area to be vacuumed is less than the minimum shadowless distance, the area to be vacuumed will have an unilluminated area corresponding to the shape of the suction port 30b9.

[0098] In this configuration, at least three point light sources of the annular lighting assembly 30b6 are arranged circumferentially around the suction port 30b9, ensuring that the light emitted by these three point light sources illuminates the area in front of the suction port 30b9. Since the at least three point light sources are arranged circumferentially around the axis of the suction port 30b9, the light emitted by these three point light sources forms a uniform illumination range around the area in front of the suction port 30b9, thereby illuminating the front end of the suction port 30b9 and the surrounding area to be cleaned. By mounting the annular lighting assembly 30b6 on the dust cup front cover 30b and positioning it close to the suction port 30b9, the distance between the annular lighting assembly 30b6 and the actual suction position is shortened. The annular lighting assembly 30b6, positioned on the dust cup front cover 30b and close to the suction port 30b9, shortens the distance between the illumination position and the actual suction position, thereby improving the accuracy of illumination in the area near the suction port 30b9. The annular lighting component 30b6 surrounds the suction port 30b9 circumferentially around its axis, providing uniform illumination to the area near the suction port 30b9, reducing shadows, and improving cleaning efficiency in dark areas. The lighting component 30b6 also includes a point light source conversion device, which can convert at least three point light sources into an annular surface light source. When the distance from the area to be vacuumed to the lighting component 30b6 is greater than the maximum shadowless distance, shadowless illumination of the area to be vacuumed can be achieved. When the distance is between the maximum and minimum shadowless distance, grayscale shadowless illumination of the area to be vacuumed can be achieved. When the distance is less than the minimum shadowless distance, an unilluminated area corresponding to the shape of the suction port 30b9 will remain in the area to be vacuumed.

[0099] In one or more alternative embodiments, such as Figures 1-6 , Figure 8 As shown, both the dust cup front cover 30b and the dust cup cylinder front cover 30b are cylindrical. One end of the dust cup front cover 30b and the dust cup cylinder 30a can be rotatably fastened together to form a dust cup assembly fastening body 30. One end of the dust cup front cover 30b and one end of the dust cup cylinder 30a are hinged together, and the two can rotate around the hinge point. The outer walls of the two are provided with a locking device (not shown in the figure) on the opposite side of the hinge point, which can cooperate and lock together. When the two are released from locking, the dust cup front cover 30b can rotate outward around the hinge point to achieve rotational separation from the dust cup cylinder 30a. After the two are separated, the user can pour out the dust, debris, hair and other dirt contained in the dust storage chamber J in the dust cup assembly 3.

[0100] This design, with the mutually rotatable and interlocking dust cup cylinder front cover 30b and dust cup cylinder front cover 30b of the dust cup assembly 3, greatly facilitates the user's decision to release the dust cup assembly 3 from the horizontal cylinder 10a end of the main unit without the need for laborious rotation. Simply pressing lightly on the interlocking device releases the dust cup cylinder front cover 30b from the dust cup cylinder 30a. The dust cup cylinder front cover 30b can automatically rotate open using its own gravity, allowing the dust cup cylinder 30a to be easily tilted to empty the dust, debris, hair, and other contaminants contained in the dust storage chamber J of the dust cup assembly 3. This convenient and quick method enhances the user experience.

[0101] In one or more alternative embodiments, such as Figures 1-4 , Figure 6 , Figure 8 As shown, the at least three point light sources are at least three LED beads arranged on the lamp panel 30b61 around the axis of the suction port 30b9. The dust cup cylinder front cover 30b includes a front cover body 30b1, a suction pipe 30b2, and an annular lighting assembly 30b6. One end of the front cover body 30b1 can be rotatably fastened to one end of the dust cup cylinder 30a. The suction pipe 30b2 extends outward from the other end of the front cover body 30b1. One end of the suction pipe 30b2 has a suction port 30b9 and a suction channel F connected to the suction port 30b9 is formed inside it. The suction channel F is used to connect with the suction structure inside the dust cup assembly 3 when the dust cup assembly 3 is working, so that dust, debris, hair and other dirt in the area to be cleaned can enter the suction channel F through the suction port 30b9 and be further sucked into the dust cup assembly 3. The annular lighting assembly 30b6 is arranged on the front cover body 30b1 on the same side as the suction pipe 30b9.

[0102] In one or more alternative embodiments, such as Figures 1-6 , Figure 8 As shown, the front cover body 30b1 includes a pin-shaft hanging ear 30b12 and a fastening groove 30b11; the pin-shaft hanging ear 30b12 is located at the bottom of the rotating fastening point between the front cover body 30b1 and the dust cup cylinder 30a; the fastening groove 30b11 is located at the top of the rotating fastening point between the front cover body 30b1 and the dust cup cylinder 30a.

[0103] Furthermore, such as Figure 1 , Figures 5-6 , Figure 8As shown, the front cover body 30b1 has a fastening groove 30b11 and a pin mounting ear 30b13 on the side near the dust cup 30a. The fastening groove 30b11 and the pin mounting ear 30b13 are arranged circumferentially opposite each other around the axis of the suction channel F. The dust cup 30a has a fastening assembly 30a12 and a pin mounting ear 30a2 on the side near the front cover body 30b1. The pin mounting ear 30a2 is mounted on the pin mounting ear 30b13. The fastening assembly 30a12 can be fastened with the fastening groove 30b11 to fix the dust cup front cover 30b to the dust cup 30a.

[0104] Please refer to Figure 1 , Figures 5-6 , Figure 8 As shown, in this embodiment, the pin-mount lug 30b13 cooperates with the pin mounting lug 30a2 to provide a rotatable connection when the dust cup front cover 30b and the dust cup 30a are assembled. The latch groove 30b11 cooperates with the latch assembly 30a12 to achieve a fastening and fixation after the dust cup front cover 30b is rotated to a predetermined position. The latch groove 30b11 and the pin-mount lug 30b13 are circumferentially opposite each other around the axis of the suction channel F, forming a stable assembly relationship between the dust cup front cover 30b and the dust cup 30a, and facilitating the assembly of both around the axis of the suction channel F.

[0105] Please refer to Figure 1 , Figures 5-6 , Figure 8 As shown, in this embodiment, the through-pin hook 30b13 and the pin mounting ear 30a2 are provided to form a rotatable connection between the dust cup front cover 30b and the dust cup 30a during assembly, facilitating positioning and assembly and improving assembly convenience. The latch groove 30b11 and the latch assembly 30a12 are provided, allowing them to interlock and fix the dust cup front cover 30b and the dust cup 30a after assembly, preventing the dust cup front cover 30b from loosening or detaching relative to the dust cup 30a. The latch groove 30b11 and the through-pin hook 30b13 are arranged circumferentially opposite each other around the axis of the suction channel F, and the latch assembly 30a12 and the pin mounting ear 30a2 are correspondingly arranged, making the assembly process between the dust cup front cover 30b and the dust cup 30a smoother and achieving a stable and reliable connection.

[0106] In one or more alternative embodiments, such as Figures 1-8As shown, the main unit 1 also includes a vertical handle portion 10b perpendicular to the horizontal cylindrical portion 10a, and the vertical handle portion 10b is equipped with a built-in power supply; one end of the horizontal cylindrical portion 10a is provided with at least two power supply spring pins 10a4, which can lead out the output terminal (not shown in the figure) of the built-in power supply to power the dust cup 30a, and then power the lamp board 30b61. The dust cup 30a can be rotated along its axis to engage with one end of the horizontal cylindrical portion 10a, and one end of the horizontal cylindrical portion 10a is provided with an adapter plate 10a3, on which at least two of the power supply spring pins 10a4 are mounted.

[0107] In one or more alternative embodiments, such as Figures 1-5 , Figures 7-8 As shown, a locking post 10a11 is provided on the top of the inner wall of the end of the horizontal cylinder 10a that mates with the dust cup cylinder 30a. The dust cup cylinder 30a includes a dust cup cylinder body 30a1. At least two locking grooves 30a11 are provided around the outer wall of the end of the dust cup cylinder body 30a1 that can rotatably engage with the locking post 10a11. The dust cup cylinder body 30a1 can be docked with the horizontal cylinder 10a and rotated to lock / unlock. After the dust cup cylinder body 30a1 and the horizontal cylinder 10a are docked and locked, their outer surfaces are flush.

[0108] Furthermore, such as Figures 1-3 , Figure 6 , Figure 8 As shown, the outer wall of the end of the dust cup body 30a1 that mates with the horizontal cylinder 10a is provided with at least two slots 30a11 that can rotatably engage with the locking post 10a11. When holding the dust cup body 30a1 and connecting it to the horizontal cylinder 10a, let the locking post 10a11 first enter the starting slot of the slot 30a11 (not shown in the attached figure), and then rotate the dust cup body 30a1 so that the locking post 10a11 slides along the slide of the slot 30a11 (not shown in the attached figure) to reach the ending slot of the slot 30a11 (not shown in the attached figure), thus completing the docking and locking of the dust cup body 30a1 and the connecting horizontal cylinder 10a. After the dust cup body 30a1 and the horizontal cylinder 10a are docked and locked, their outer surfaces are flush. The dust cup body 30a1 can be removed from the horizontal cylinder 10a by reversing the above steps.

[0109] Furthermore, such as Figures 1-3 , Figure 6 , Figure 8As shown, a slot 30a11 is provided at one end of the dust cup 30a near the horizontal cylindrical portion 10a; a retaining post 10a11 is provided at one end of the horizontal cylindrical portion 10a near the dust cup 30a. The dust cup 30a is detachably connected to the dust cup 30a via the retaining post 10a11 and the slot 30a11. The slot 30a11 and the retaining post 10a11 cooperate with each other to realize the connection and disconnection between the dust cup 30a and the horizontal cylindrical portion 10a of the main unit 1. The slot 30a11 is located at one end of the dust cup 30a near the horizontal cylinder 10a, and the locking pin 10a11 is located at the same end. The locking pin 10a11 can be inserted into the slot 30a11 and engage with it, thus achieving a detachable connection between the dust cup 30a and the horizontal cylinder 10a. When cleaning or maintenance is required, the locking pin 10a11 disengages from the slot 30a11, allowing for quick separation of the dust cup 30a from the horizontal cylinder 10a, facilitating cleaning and improving ease of use.

[0110] With this configuration, the slot 30a11 and the locking post 10a11 are provided on the dust cup cylinder 30a, allowing the dust cup cylinder 30a and the horizontal cylinder 10a containing the high-pressure blower 10A to be detachably connected via the locking post 10a11 and the slot 30a11. When cleaning of the dust storage chamber J is required, the front cover 30b of the dust cup cylinder is driven away from the dust cup cylinder 30a, causing the locking post 10a11 to disengage from the slot 30a11, thereby opening the front cover 30b relative to the dust cup cylinder 30a to expose the dust storage chamber J, facilitating the cleaning of accumulated dust, debris, hair, and other contaminants within the dust storage chamber J. After cleaning, the dust cup front cover 30b is driven back towards the dust cup 30a, causing the retaining pin 10a11 to re-engage into the retaining groove 30a11, thus restoring the connection between the dust cup front cover 30b and the dust cup 30a. The cooperation between the retaining pin 10a11 and the retaining groove 30a11 ensures the stability of the connection between the dust cup front cover 30b and the dust cup 30a, and also facilitates the opening and cleaning of the dust storage chamber J.

[0111] In one or more alternative embodiments, such as Figure 6 , Figure 8As shown, the conductive device consists of at least two power springs (positive power spring P and negative power spring Q) located at the bottom of the dust cup body 30a1. One end of each power spring is electrically connected to a power supply spring 10a4 on one end face of the dust cup body 30a1, and the other end of each power spring is electrically connected to a power take-off spring 30b4 on the other end face of the dust cup body 30a1. When the dust cup front cover 30b is disengaged from the dust cup 30a, the power springs are disconnected from the power take-off spring 30b4. When the dust cup 30a is disengaged from the horizontal cylinder 10a, the power springs are disconnected from the power supply spring 10a4.

[0112] In one or more alternative embodiments, the bottom of the dust cup body 30a1 is provided with a conductive groove and a conductive groove cover. After the power spring is installed in the conductive groove and the conductive groove cover is closed, the circumference of the dust cup body 30a1 can be insulated.

[0113] In one or more alternative embodiments, the dust cup body 30a1 is injection molded together with at least two power springs wrapped around its bottom.

[0114] In one or more alternative embodiments, such as Figures 1-6 , Figure 8 As shown, the dust cup body 30a1 also includes a fastening assembly 30a12, a pin mounting ear 30a13, and a pin (not shown in the attached figure); the fastening assembly 30a12 is located at the top of the rotatable engagement point between the dust cup body 30a1 and the dust cup front cover 30b, and can be fastened onto the fastening groove 30b11; the pin mounting ear 30a13 is located at the bottom of the rotatable engagement point between the dust cup body 30a1 and the dust cup front cover 30b; the pin can pass through the pin mounting ear 30a13 and be threaded through the pin mounting ear 30b12, so that the front cover body 30b1 and the dust cup body 30a1 are hinged.

[0115] In one or more alternative embodiments, such as Figures 7-8 As shown, a main control board bracket 10c is installed inside the intersection of the horizontal cylindrical section 10a and the vertical handle section 10b. A main control board M is mounted on the main control board bracket 10c. The main control board M is electrically connected to a built-in power supply, which can supply power to the high-pressure blower 10A and the power supply spring pin 10a4, thereby realizing power supply control of the high-pressure blower 10A and power transmission to the power supply spring pin 10a4. The built-in power supply is located inside the vertical handle section 10b and is electrically connected to the main control board M to provide power to the main control board M and the electrical components electrically connected to it.

[0116] In one or more alternative embodiments, such as Figures 1-5 , Figures 7-8As shown, the vertical handle portion 10b is disposed on the outer peripheral surface of the high-pressure blower 10A and is perpendicular to the axis of the high-pressure blower 10A. Thus, when the user holds the vertical handle portion 10b to operate the handheld vacuum cleaner, the direction of the hand grip can form an angle with the extension direction of the high-pressure blower 10A, thereby improving the grip posture during use.

[0117] In one or more alternative embodiments, such as Figure 1 , Figure 3 , Figures 7-8 As shown, a touch control 10b1 is provided on the outer wall of the vertical handle portion 10b facing the air outlet and near the intersection of the horizontal cylinder portion 10a and the vertical handle portion 10b. The touch control 10b1 includes a button panel 10b14, a start / stop button 10b11, a shift lever 10b12, and a button cover 10b13. The button panel 10b14 is provided with a start / stop switch (not shown in the figure), which is electrically connected to the main control board. The start / stop button 10b11 can trigger the start / stop switch. The shift lever 10b12 is engaged with the shift switch (not shown in the figure) which is electrically connected to the main control board. The button cover 10b13 covers the surface of the vertical handle portion 10b to protect the button panel 10b14, the start / stop button 10b11, and the shift lever 10b12.

[0118] In one or more alternative embodiments, such as Figure 1 , Figure 3 , Figures 5-6 , Figure 8 As shown, one end of the power spring that can be electrically connected to the power supply spring 10a4 protrudes from one end face of the dust cup body 30a1, and the portion of the power spring that protrudes from the end face of the dust cup body 30a1 is the rear contact portion 30a4'; one end of the power spring that can be electrically connected to the power take-off spring 30b4 protrudes from the other end face of the dust cup body, and the portion of the power spring that protrudes from the other end face of the dust cup body 30a1 is the front contact portion 30a4; the power spring extends from one side of the dust cup body 30a1 to the other side, and is electrically connected to the power supply spring 10a4 and the power take-off spring 30b4 through the front contact portion 30a4 and the rear contact portion 30a4', respectively.

[0119] Furthermore, an annular groove 30b13 is provided on the side of the front cover body 30b1 away from the dust cup assembly 3. The light-transmitting cover plate 30b8 is installed in the annular groove 30b13. The lamp plate 30b61 of the annular lighting assembly 30a6 is located in the annular groove 30b13. The other part of the lamp plate 30b61 is electrically connected to the power-taking spring 30b4. The power-taking spring 30b4 passes through the lamp plate bracket 30b63 and extends in the direction away from the annular groove 30b13 to the side of the front cover body 30b1 near the dust cup assembly 3. The power-taking spring 30b4 is electrically connected to the front contact portion 30a4 of the dust cup cylinder 30a, and then continues to be electrically connected to the rear contact portion 30a4' of the dust cup cylinder 30a through the power spring. Simultaneously, when the rear contact portion 30a4' of the dust cup cylinder 30a is electrically connected to the power supply spring pin 10a4 of the horizontal cylinder portion 10a, and the power supply spring pin 10a4 is electrically connected to the output terminal of the built-in power supply, the lamp plate 30b61 of the lighting assembly 30a6 can draw power from the output terminal of the built-in power supply of the handheld vacuum cleaner. When the user presses the start / stop button 10b11, the high-pressure fan 10A starts to work, and the lamp beads on the lamp plate 30b61 light up. The ring lighting assembly 30a6 can be stably installed on the front cover 30b of the dust cup cylinder, and obtains power from the built-in power supply through the dust cup assembly 3, realizing "shadowless lighting" of the area to be vacuumed.

[0120] In one or more alternative embodiments, such as Figures 1-3 , Figure 8 As shown, a connecting channel G is formed inside the dust cup cylinder body 30a1. One end of the connecting channel G is connected to the dust suction channel F, and the other end of the connecting channel G is connected to the high-pressure blower 10A. A gas flow channel is established sequentially between the dust suction port 30b9, the dust suction channel F, the connecting channel G and the high-pressure blower 10A.

[0121] In one or more alternative embodiments, such as Figure 1 , Figure 3 , Figures 6-8 As shown, the dust cup assembly 3 also includes a HEPA filter 30c, which is installed in the connecting channel G. The HEPA filter 30c can engage with the inner wall of the dust cup body 30a1. The HEPA filter 30c, the dust cup body 30a1, and the dust cup front cover 30b together form a dust storage chamber J for dust collection.

[0122] Furthermore, the dust cup 30a includes a dust cup body 30a3 and a HEPA filter 30c. The dust cup body 30a3 has a connecting channel G inside. One end of the connecting channel G is connected to the suction channel F, and the other end is connected to the high-pressure blower 10A, thereby establishing a gas flow channel sequentially between the suction port 30b9, the suction channel F, the connecting channel G, and the high-pressure blower 10A. The HEPA filter 30c is installed within the connecting channel G. A dust storage chamber J is formed between the HEPA filter 30c, the dust cup body 30a3, and the dust cup front cover 30b. The dust storage chamber J is used to collect dust, debris, hair, and other contaminants sucked in through the suction port 30b9.

[0123] Specifically, such as Figure 1 , Figure 3 , Figures 6-8 As shown, in this embodiment, the dust cup body 30a3 forms the main structure of the dust cup 30a and provides a structural basis for the connecting channel G and the dust storage chamber J. The connecting channel G connects the suction channel F to the high-pressure blower 10A, allowing the suction airflow to flow between the suction port 30b9, the suction channel F, the connecting channel G, and the high-pressure blower 10A. The HEPA filter 30c is disposed in the connecting channel G and filters the airflow entering the dust cup 30a, separating dust and other contaminants from the airflow and retaining the contaminants in the dust storage chamber J.

[0124] This configuration creates a connecting channel G inside the dust cup body 30a3, with one end of the connecting channel G connected to the suction channel F and the other end connected to the high-pressure blower 10A. This establishes a continuous gas flow channel between the suction port 30b9, the suction channel F, the connecting channel G, and the high-pressure blower 10A, ensuring the continuity and stability of the suction airflow. The HEPA filter 30c is installed within the connecting channel G, allowing the airflow entering the dust cup 30a to be filtered before flowing to the high-pressure blower 10A, thereby separating the airflow from the dirt and improving dust collection efficiency. The dust storage chamber J is formed between the HEPA filter 30c, the dust cup body 30a3, and the dust cup front cover 30b, providing a dedicated space for the intake of dust, debris, hair, and other contaminants, facilitating centralized collection and subsequent cleaning. Through the cooperation of the dust cup body 30a3, the connecting channel G, the HEPA filter 30c, and the dust collection chamber J, the dust cup 30a simultaneously achieves the functions of airflow communication, dirt filtration, and dirt collection, thereby improving the overall dust collection effect and performance of the handheld vacuum cleaner. When the dust collection chamber J needs to be cleaned, the dust cup front cover 30b is driven away from the dust cup 30a, causing the dust cup front cover 30b to rotate around the pin mounting ear 30a2. The latch assembly 30a12 and the latch groove 30b11 are disengaged, releasing the dust cup front cover 30b from the dust cup 30a. Subsequently, the dust cup front cover 30b is continued to rotate relative to the dust cup 30a, thereby opening the dust collection chamber J, making it convenient for the user to clean the dust, debris, hair, and other dirt accumulated in the dust collection chamber J. After cleaning, the dust cup front cover 30b is reset, and the fastening assembly 30a12 is re-engaged with the fastening groove 30b11 to re-secure the dust cup front cover 30b to the dust cup 30a. The cooperation between the fastening groove 30b11 and the fastening assembly 30a12 ensures the stability of the connection between the dust cup front cover 30b and the dust cup 30a, facilitating quick disassembly and cleaning of the dust collection chamber J, thereby improving the convenience of cleaning operations. When the handheld vacuum cleaner is working, external airflow carrying dust, debris, hair, and other contaminants enters the dust cup 30a through the suction port 30b9. During the airflow, it passes through the HEPA filter 30c, where the contaminants are blocked or separated and retained in the dust cup 30a, thus achieving filtration and dust collection.

[0125] In one or more alternative embodiments, such as Figures 1-5 , Figure 6 , Figure 8As shown, the point light source conversion device is a light-transmitting cover plate 30b63 installed on the end face of the dust cup cylinder front cover 30b on the same side as the dust suction port 30b9. One end of the dust cup cylinder 30a is hinged to the dust cup cylinder front cover 30b, and one end of the dust cup cylinder front cover 30b can be rotatably fastened to one end of the dust cup cylinder 30a. The dust cup cylinder front cover 30b includes a front cover body 30b1. The ring-shaped lighting assembly 30b6 includes a lamp panel 30b61, a lamp panel bracket 30b62, and a light-transmitting cover 30b63. The lamp panel 30b61 is ring-shaped and has at least three LED beads. The lamp panel bracket 30b62 is detachably connected to the front cover body 30b1 and can be used to install the lamp panel 30b61 and a power-taking spring pin 30b4 that is electrically connected to the lamp panel 30b61 and draws power outward. The power-taking spring pin 30b4 can be electrically connected to the dust cup 30a. The light-transmitting cover 30b63 allows the light emitted by the LED beads to pass through the light-transmitting cover 30b63 and be emitted evenly, converting at least three point light sources into a ring-shaped surface light source.

[0126] In one or more alternative embodiments, such as Figure 2 , Figure 4 , Figure 6 , Figure 8 As shown, an annular groove 30b13 is provided on the end face of the front cover 30b of the dust cup cylinder on the same side as the suction port 30b9. The light-transmitting cover 30b8 is detachably fastened to the annular groove 30b13 to protect the lamp plate 30b61. The light-transmitting cover 30b8 is installed on the annular groove 30b13 on the front cover body 30b1 so that the lamp plate 30b61 is sealed within the annular groove 30b13. Through the arrangement of the light-transmitting cover 30b8, the lamp plate 30b61 is accommodated within the space defined by the annular groove 30b13 and the light-transmitting cover 30b8, thereby providing a sealing and protection function for the lamp plate 30b61. The light-transmitting cover 30b8 blocks the lamp plate 30b61 without affecting its light emission, thereby reducing the impact of external factors such as dust, debris, and moisture on the lamp plate 30b61. By installing the light-transmitting cover plate 30b8 on the annular groove 30b13, the lamp plate 30b61 is sealed within the annular groove 30b13, providing protection for the lamp plate 30b61. This reduces the adverse effects of dust, debris, and external contact on the lamp plate 30b61, improving its operational stability and service life. The light-transmitting cover plate 30b8 seals the lamp plate 30b61, ensuring normal light output while improving the structural integrity of the lamp plate 30b61's installation location, thereby enhancing the overall assembly effect of the dust cup front cover 30b.

[0127] Furthermore, such as Figure 1 , Figures 5-6 , Figure 8As shown, the power-taking springs 30b4 are configured in at least one set, with at least two power-taking springs 30b4 in each set. One end of each power-taking spring 30b4 is received within the annular groove 30b13 and electrically connected to the lamp panel 30b61. The other end of each power-taking spring 30b4 extends through the annular groove 30b13 and towards the dust cup assembly 3, thereby electrically connecting to the dust cup assembly 3. The power-taking springs 30b4 establish an electrical connection path between the lamp panel 30b61 and the dust cup assembly 3, enabling the dust cup assembly 3 to supply power to the lamp panel 30b61, ensuring that the LEDs on the lamp panel 30b61 can emit light normally.

[0128] Furthermore, such as Figure 6 , Figure 8 As shown, the annular lamp panel 30b61 is partially located within the annular groove 30b13. The annular lamp panel 30b61 is arranged along the extending direction of the annular groove 30b13, allowing it to be distributed circumferentially around the suction port 30b9, thus forming a surround lighting structure near the suction port 30b9. By placing the annular lamp panel 30b61 within the annular groove 30b13, the annular lighting assembly 30b6 can be fixedly mounted on the dust cup front cover 30b, and the mounting position of the annular lamp panel 30b61 can be closer to the suction port 30b9 for direct illumination of the actual suction area.

[0129] In one or more alternative embodiments, the lighting assembly 30b6 has four or five point light sources evenly distributed within it. Specifically, the annular lamp panel 30b61 has four or five LEDs evenly distributed within it.

[0130] In one or more alternative embodiments, at least six point light sources are evenly distributed within the lighting assembly 30b6. Specifically, at least six LEDs are evenly distributed within the annular lamp panel 30b61.

[0131] Thus, multiple LEDs of the ring-shaped lighting assembly 30b6 are arranged circumferentially around the suction port 30b9, allowing the light emitted by the LEDs to illuminate the area in front of the suction port 30b9. Since the LEDs are arranged circumferentially around the axis of the suction port 30b9, the light emitted by the LEDs forms a uniform illumination range around the area in front of the suction port 30b9, thereby illuminating the front of the suction port 30b9 and the surrounding area to be cleaned. By mounting the ring-shaped lighting assembly 30b6 on the dust cup front cover 30b and positioning it close to the suction port 30b9, the distance between the ring-shaped lighting assembly 30b6 and the actual suction position is shortened.

[0132] In one or more alternative embodiments, the high-pressure fan 10A built into the horizontal cylinder 10a can suck in dust from the suction port 30b9, filter it, and then discharge the exhaust gas from the other end of the horizontal cylinder 10a; wherein, one end of the dust cup cylinder 30a and one end of the horizontal cylinder 10a can be rotatably docked to realize the docking of the dust cup assembly 3 and the main unit 1, and the light generated by the ring lighting assembly shines along the axial direction of the suction port 30b9.

[0133] In one or more alternative embodiments, such as Figure 1 , Figures 5-6 , Figure 8 As shown, the dust cup front cover 30b also includes a negative pressure baffle 30b3 and a rotary spring 30b5; the negative pressure baffle 30b3 includes a hinged end (not shown in the figure) and a blocking end 30b31; the hinged end is hinged to the root of the suction pipe 30b9 of the front cover body 30b1, and the blocking end closes the suction channel F when the handheld vacuum cleaner is stopped; the rotary spring 30b5 is supported between the front cover body 30b1 and the negative pressure baffle 30b3, driving the negative pressure baffle 30b3 to close the suction channel F. One end of the negative pressure baffle 30b3 is rotatably connected to the suction pipe 30b2, and the other end of the negative pressure baffle 30b3 is the blocking end 30b31. The negative pressure baffle 30b3 is located on the side of the suction pipe 30b2 near the dust cup 30a, and the blocking end can block the suction channel F.

[0134] Furthermore, such as Figure 1 , Figure 6 , Figure 8 As shown, during operation, under the push of the airflow, the blocking end 30b31 of the negative pressure baffle 30b3 is opened to connect the dust suction channel F with the dust cup assembly 3.

[0135] With this configuration, the negative pressure baffle 30b3 can open and close the suction channel F while rotating. One end of the negative pressure baffle 30b3 is rotatably connected to the suction pipe 30b2, allowing it to automatically open under airflow during operation and automatically close when operation stops, thus blocking the suction channel F. By blocking the suction channel F with the baffle end, the amount of dust, debris, and hair that has been sucked in is effectively reduced from falling back through the suction channel F after the handheld vacuum cleaner stops working, maintaining the stability of the dirt collection state in the dust cup 30a and improving cleaning efficiency. The cooperation between the light-transmitting cover 30b8 and the negative pressure baffle 30b3 ensures stable illumination of the light panel 30b61 on the front cover 30b of the dust cup, achieving automatic opening and closing control of the suction channel F, thereby improving the overall performance of the handheld vacuum cleaner.

[0136] In one or more alternative embodiments, such as Figures 7-8 As shown, a silicone air guide ring 10A1 is sandwiched between the end of the horizontal cylinder 10a facing the dust cup cylinder 30a and the air inlet end of the high-pressure blower 10A. A blower tail silicone 10A2 is sandwiched between the end of the high-pressure blower 10A facing away from the air inlet end and the end of the horizontal cylinder 10a facing away from the dust cup cylinder 30a. The gap space enclosed by the horizontal cylinder 10a, the silicone air guide ring 10A1 and the high-pressure blower 10A is the exhaust channel H. The end of the exhaust channel H is the air outlet located at the end of the horizontal cylinder 10a facing away from the dust cup cylinder 30a (not shown in the figure).

[0137] In one or more alternative embodiments, such as Figures 7-8 As shown, the dust cup 30a has an exhaust channel H and an exhaust port (not shown in the attached figure), and the dust cup 30a is connected to the outside through the exhaust channel H and the exhaust port. A silicone air guide ring 10A1 and an air outlet grille (not shown in the attached figure) are also installed inside the horizontal cylindrical part 10a, and a built-in power supply is provided inside the vertical handle part 10b. The silicone air guide ring 10A1 is installed inside the exhaust channel H to provide suction power during operation, allowing external airflow to flow through the suction port 30b9, the suction channel F, and the dust cup 30a, and further discharged to the outside through the exhaust channel H and the exhaust port. The air outlet grille is installed on the side of the silicone air guide ring 10A1 away from the dust cup 30a and is located inside the exhaust channel H, to further block and protect the airflow passing through the exhaust channel H.

[0138] In one or more alternative embodiments, such as Figure 1 , Figure 3 , Figures 7-8 As shown, the exhaust channel H of the horizontal cylinder 10a is provided with an air outlet grille, and the air outlet grille is provided with multiple exhaust holes (not shown in the attached figure). The air in the dust cup cylinder 30a is connected to the outside through the exhaust channel H and the exhaust holes in sequence.

[0139] In one or more alternative embodiments, such as Figures 7-8 As shown, the inner wall step of the horizontal cylindrical part 10a facing the dust cup cylinder 30a can also be detachably connected to an air inlet grille 10a2. The air inlet grille 10a2 is located on the inner wall step of the horizontal cylindrical part 10a, further away from the locking post 10a11 at the open end. The air inlet grille 10a2 can further prevent the particulate matter mixed with the exhaust gas that has passed through the HEPA filter 30c from passing through the air inlet grille 10a2 again and damaging the high-pressure blower 10A. The air inlet grille 10a2 can further prevent particulate matter from passing through the air inlet grille 10a2 and reaching the high-pressure blower 10A when the user maintains and replaces the HEPA filter 30c, so that there are foreign objects in the high-pressure blower 10A when the handheld vacuum cleaner is turned on again, which would damage the high-pressure blower 10A.

[0140] Furthermore, such as Figures 7-8 As shown, an inner support 10a5 is provided at the end of the horizontal cylinder 10a away from the air inlet of the high-pressure blower 10A. This inner support 10a5 can be detachably connected to a step (not shown in the attached diagram) on the inner wall of the horizontal cylinder 10a. The inner support 10a5 is covered with ventilation holes to ensure that the exhaust outlet at the end of the exhaust channel H, located at the end of the horizontal cylinder 10a facing away from the dust cup 30a, can discharge the exhaust gas generated by the high-pressure blower 10A during operation. The inner support 10a5 has openings corresponding to the end face of the silicone rubber 10A2 at the tail of the blower, ensuring that the silicone rubber 10A2 at the tail of the blower can be securely engaged with these openings. Furthermore, the silicone rubber 10A2 at the tail of the blower further absorbs the vibration and noise generated by the high-pressure blower 10A during operation.

[0141] In one or more alternative embodiments, such as Figure 1 , Figure 3 , Figures 7-8 As shown, a rear cover 10a1 is also provided on the outer side of the air outlet grille inside the horizontal cylinder 10a. The rear cover 10a1 and the end of the horizontal cylinder 10a away from the dust cup assembly 3 clamp the air grille 10a6 between them, which can prevent the air outlet grille from being detached from the horizontal cylinder 10a due to the impact of the high positive pressure output from the air outlet of the high pressure fan 10A during operation.

[0142] In one or more alternative embodiments, such as Figures 7-8 As shown, an exhaust sponge mesh (not shown in the attached figure) is also sandwiched between the inner support 10a5 and the silicone 10A2 at the tail of the fan. The exhaust sponge mesh can further reduce the noise generated by the high-pressure fan 10A when the handheld vacuum cleaner is working, and can also further reduce the dust and impurity content of the exhaust gas discharged from the exhaust port at the end of the horizontal cylinder 10a facing away from the dust cup cylinder 30a.

[0143] In the technical solutions described in the above embodiments, the dust cup assembly 3 provides negative pressure suction so that external dust, debris, hair, and other contaminants can enter the handheld vacuum cleaner through the suction port 30b9. The dust cup front cover 30b is used to directly contact or approach the area to be cleaned and serves as the airflow inlet. The ring-shaped lighting assembly 30b6 is disposed on the dust cup front cover 30b and positioned close to the suction port 30b9, so that the light emission position of the ring-shaped lighting assembly 30b6 is close to the suction position. The ring-shaped lighting assembly 30b6 is arranged circumferentially around the suction port 30b9, so that the light emitted by the ring-shaped lighting assembly 30b6 can illuminate the area in front of the suction port 30b9. Since the ring-shaped lighting assembly 30b6 is arranged circumferentially with the axis of the suction port 30b9 as the axis, the light emitted by the ring-shaped lighting assembly 30b6 forms a uniform illumination range around the front of the suction port 30b9, thereby illuminating the front end of the suction port 30b9 and the surrounding area to be cleaned. By mounting the ring light assembly 30b6 on the front cover 30b of the dust cup and positioning it close to the suction port 30b9, the distance between the ring light assembly 30b6 and the actual suction position is shortened.

[0144] When a user holds this handheld vacuum cleaner to clean areas such as desktops, sofa crevices, bed edges, car corners, or under furniture, the dust cup assembly 3 generates suction, drawing in dirt through the suction port 30b9. The annular lighting assembly 30b6, located on the front cover 30b of the dust cup, illuminates the area in front of the suction port 30b9, allowing the user to clearly observe the distribution of dust, hair, or debris at the corresponding location and adjust the suction path and angle accordingly. Positioning the annular lighting assembly 30b6 on the front cover 30b of the dust cup, close to the suction port 30b9, effectively shortens the distance between the illuminated area and the actual suction location. This avoids the problem in existing technologies where the lighting is located on the main body or handle, causing a misalignment between the illuminated area and the actual suction area, thus improving the accuracy of illumination of the actual cleaning location. The ring-shaped lighting component 30b6 is arranged circumferentially around the suction port 30b9, with the axis as its axis. This provides a more uniform lighting environment for the area in front of the suction port 30b9, reducing shadows caused by unilateral lighting and improving visibility in dark, narrow, and obstructed areas. The light generated by the ring-shaped lighting component 30b6 illuminates along the axis of the suction port 30b9, ensuring that the lighting direction is essentially consistent with the suction direction. This allows the illuminated area seen by the user during vacuuming to correspond to the actual vacuumed area, thereby improving cleaning efficiency and effectiveness.

[0145] In the technical solutions described in the above embodiments, the suction pipe 30b2 is preferably a hollow tubular component, the front cover body 30b1 is preferably an annular flange protruding radially outward along the outer periphery of the suction pipe 30b2, and the annular groove 30b13 is preferably an annular groove provided on the front cover body 30b1. The annular lamp plate 30b61 is preferably an annular flexible lamp plate and is provided with multiple LED beads. The power-taking spring pin 30b4 and the power-supply spring pin 10a4 are preferably columnar conductive components and are positive and negative electrical connection posts. The power spring is preferably a sheet-shaped elastic conductive component and is a positive and negative conductive sheet. The dust cup cylinder body 30a3 is preferably a cup-shaped or cylindrical shell, the light-transmitting cover plate 30b8 is preferably an annular light-transmitting cover plate 30b8, and the negative pressure baffle 30b3 is preferably a sheet-shaped flip-plate structure. The latch groove 30b11 and the card slot 30a11 are preferably groove-shaped structures, the latch assembly 30a12 and the card post 10a11 are preferably protruding snap-fit ​​structures, the pin shaft hanging ear 30b13 is preferably a shaft hole or shaft seat, and the pin shaft mounting ear 30a2 is preferably a columnar rotating shaft structure.

[0146] The following detailed description of the foregoing embodiments will further elaborate on the specific working methods and principles presented in the embodiments of this application from the perspective of the user using the handheld vacuum cleaner.

[0147] Please refer to Figures 1-8In the specific embodiments described above, when the handheld vacuum cleaner is working, the dust cup assembly 3 forms a suction path through the suction channel F and the suction port 30b9 to perform suction. The circular lighting assembly 30b6 is powered by the electrical connection between the dust cup assembly 3 and the circular lighting assembly 30b6, enabling it to emit light normally and illuminate the area near the suction port 30b9. Since the suction tube 30b2 has a suction channel F communicating with the suction port 30b9, it ensures that dirt in the area to be cleaned smoothly enters the vacuum cleaner through the suction port 30b9 for suction. A radially protruding front cover body 30b1 is provided on the outer periphery of the suction tube 30b2, and an annular groove 30b13 is formed on the front cover body 30b1. The annular groove 30b13 serves as the light-transmitting and mounting position for the circular lighting assembly 30b6, allowing the circular lighting assembly 30b6 to be mounted on the dust cup front cover 30b. Because part of the ring lighting component 30b6 is installed within the annular groove 30b13, and another part extends to the side of the front cover body 30b1 near the dust cup assembly 3 and is electrically connected to the dust cup assembly 3, the structural compactness of the dust cup cylinder front cover 30b is improved. By directly placing the ring lighting component 30b6 at the position of the front cover body 30b1 corresponding to the dust cup cylinder front cover 30b, the ring lighting component 30b6 is placed closer to the suction port 30b9, thereby shortening the distance between the lighting position and the actual suction position. This makes it easier for the light to cover the area to be cleaned near the suction port 30b9, improving the accuracy of lighting and the cleaning effect when cleaning in dark places.

[0148] Please refer to Figures 1-8In a specific embodiment, the ring lighting assembly 30b6 is configured to include a ring light plate 30b61, with a portion of the ring light plate 30b61 located within the ring groove 30b13. This allows the ring lighting assembly 30b6 to be arranged circumferentially around the dust suction port 30b9, thereby creating a uniform lighting range around the dust suction port 30b9 and reducing the problems of insufficient local lighting or shadows caused by unilateral lighting. The ring light plate 30b61 is housed within the ring groove 30b13, providing installation limitation and protection for the ring light plate 30b61, preventing it from loosening, shifting, or being exposed and damaged, thus improving the stability of the ring lighting assembly 30b6 installation and the compactness of the overall structure. At least one set of power-feeding springs 30b4 is provided to form an electrical connection path between the ring light plate 30b61 and the dust cup assembly 3, enabling power supply without the need for a separate external wire. Because one end of the power-collecting spring pin 30b4 is electrically connected to the annular lamp plate 30b61, and the other end extends towards the dust cup assembly 3 and is electrically connected to the dust cup assembly 3, the annular lamp plate 30b61 is kept close to the suction port 30b9, thereby improving the accuracy of illumination of the actual suction area and improving the effect of cleaning in dark places. At least one set of power-collecting spring pins 10a4 is provided inside the horizontal cylindrical section 10a. The power-collecting spring pins 10a4 are used to form a corresponding conductive engagement with the power-collecting spring pins 30b4 provided in the front structure of the horizontal cylindrical section 10a, providing a power transmission path for the annular lighting assembly 30b6. The dust cup cylinder 30a is installed between the dust cup cylinder front cover 30b and the high-pressure blower 10A, thereby positioning the dust cup cylinder 30a in the middle of the suction airflow passage, and is used to collect dust, debris, hair, and other dirt sucked in by the dust cup cylinder front cover 30b during the suction process.

[0149] Please refer to Figures 1-8In a specific embodiment, at least two power supply springs 10a4 are provided inside the horizontal cylindrical section 10a, and at least two power supply springs are provided on the dust cup 30a, so that the power supply springs 10a4 can be electrically connected to the power take-off springs 30b4 through the power supply springs, thereby establishing a stable conductive path between the built-in power supply in the main unit 1 and the dust cup front cover 30b. Power is supplied to the front-end ring lighting component 30b6 without additional exposed wires, simplifying the overall wiring structure and improving the neatness and reliability of the assembly. The dust cup 30a is positioned between the dust cup front cover 30b and the main unit 1, and the power supply springs are integrated into the dust cup 30a, allowing the dust cup 30a to simultaneously serve as a structural connection and electrical connection transition, thereby improving the overall structural integration. The vertical handle portion 10b is positioned on the outer periphery of the high-pressure blower 10A, and is perpendicular to the axis of the high-pressure blower 10A. This allows users to adopt a more natural hand posture when holding the handheld vacuum cleaner, reducing the problem of continuous wrist deflection or twisting caused by the vertical handle portion 10b being essentially coaxial with the suction direction. This reduces operational burden and improves grip comfort. The coordinated arrangement of the horizontal cylinder portion 10a, dust cup 30a, power spring, and vertical handle portion 10b, which integrates the high-pressure blower 10A, ensures suction, dust collection, and light power supply functions, improving the overall ergonomics of the machine. This enhances cleaning efficiency and user experience in scenarios such as desktops, crevices, corners, and dark places.

[0150] Please refer to Figures 1-8In a specific embodiment, the front contact portion 30a4 is located on the side of the dust cup 30a near the front cover 30b of the dust cup 30a, to correspond and cooperate with the power-taking spring pin 30b4. The rear contact portion 30a4' is located on the side of the dust cup 30a near the high-pressure blower 10A, to correspond and cooperate with the power-supply spring pin 10a4. The power spring is located on the dust cup 30a and is used to transmit electrical energy between the front contact portion 30a4 and the rear contact portion 30a4'. The front contact portion 30a4 is located on one side of the dust cup 30a and the rear contact portion 30a4' is located on the other side of the dust cup 30a, and the two are electrically connected by the power spring, forming an electrical transmission path at the dust cup 30a, thereby realizing electrical conduction between the power-taking spring pin 30b4 and the power-supply spring pin 10a4. The power spring is positioned on the dust cup 30a, allowing the dust cup 30a to not only serve as a dust storage and structural connector but also as an electrical connection transition, thereby improving the overall structural integration. The front contact portion 30a4, the rear contact portion 30a4', and the power spring form a conductive path, preventing exposed wires from crossing the connection points of various components and improving the overall structural neatness. The power spring enables electrical connection between the power supply spring 10a4 and the power take-up spring 30b4, providing a stable power supply to the ring lighting component 30b6, thus ensuring effective illumination of the area near the suction port 30b9 during vacuuming and improving cleaning efficiency.

[0151] Please refer to Figures 1-8In a specific embodiment, during operation, the built-in power supply in the vertical handle portion 10b supplies power to the main control board M. The main control board M supplies power to the high-pressure blower 10A in the horizontal cylinder portion 10a, causing the high-pressure blower 10A to operate within the exhaust channel H. Simultaneously, the main control board M supplies power to the annular lamp plate 30b61 via the power supply spring pin 10a4, the rear contact portion 30a4', the power spring, the front contact portion 30a4, and the power-taking spring pin 30b4, causing the annular lamp plate 30b61 to emit light. Since the annular lamp plate 30b61 is located within the annular groove 30b13 and surrounds the suction port 30b9 circumferentially with the axis of the suction port 30b9 as its axis, the light emitted by the annular lamp plate 30b61 can illuminate the area near the suction port 30b9 along its axial direction. After the high-pressure blower 10A starts operating, it creates a negative pressure suction effect in the exhaust channel H, causing external airflow to enter the suction channel F through the suction port 30b9. At this time, driven by the airflow, the negative pressure baffle 30b3 rotates and opens around its rotating connection, thereby connecting the suction channel F with the dust cup assembly 3. External airflow carrying dust, debris, hair, and other contaminants sequentially enters the connecting channel G through the suction port 30b9 and the suction channel F. When passing through the HEPA filter 30c, the contaminants are separated and retained in the dust storage chamber J. The airflow continues to flow to the high-pressure blower 10A and enters the exhaust channel H, finally being discharged to the outside through the exhaust port. When the system stops working, the built-in power supply stops supplying power to the main control board M, the high-pressure fan 10A stops operating, the ring light panel 30b61 stops emitting light, the airflow propulsion in the dust suction channel F disappears, and the negative pressure baffle 30b3 closes under its own weight or reset action, blocking the dust suction channel F and reducing the amount of dirt in the dust storage chamber J falling back or leaking out through the dust suction channel F. When it is necessary to clean the dust storage chamber J, the front cover 30b of the dust cup is driven to disengage from the dust cup 30a, causing the front cover 30b of the dust cup to rotate around the pin mounting ear 30a2, thereby disengaging the fastener assembly 30a12 from the fastener groove 30b11 to open the dust storage chamber J, facilitating the cleaning of dust, debris, hair, and other dirt accumulated in the dust storage chamber J. After cleaning, drive the front cover 30b of the dust cup to rotate and reset towards the dust cup 30a, so that the fastener assembly 30a12 is re-fastened to the fastener groove 30b11, thereby fixing the front cover 30b of the dust cup to the dust cup 30a again.When it is necessary to disassemble the dust cup 30a from the horizontal cylinder 10a containing the high-pressure blower 10A for maintenance or further cleaning, the locking pin 10a11 should be disengaged from the locking groove 30a11 to separate the dust cup 30a from the horizontal cylinder 10a. After maintenance, the locking pin 10a11 should be re-engaged into the locking groove 30a11 to restore the connection between the horizontal cylinder 10a and the dust cup 30a.

[0152] In all the above embodiments, the structural fixed connection is made by integral molding, snap-fitting, screwing, or press-fitting; the detachable connection is made by snap-fitting the snap-fit ​​post and the snap-fitting the snap-fitting assembly; the rotatable connection is made by the cooperation of the rotating post and the through pin shaft lug; and the conductive connection is made by welding, plugging, abutting, or elastic contact connection.

[0153] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. This disclosure is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this disclosure is limited only by the appended claims. Thus, if these modifications and variations of the invention fall within the scope of the claims of the invention and their equivalents, the invention is also intended to include these modifications and variations.
