Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, specifically to a structure of an integrated suction and blowing dust collector. Background Technology

[0002] Portable vacuum cleaners with built-in power supplies are widely used in people's lives. They have now evolved into multi-functional vacuum cleaners that can both vacuum and blow air, achieving the functions of vacuuming, blowing, extracting, and charging. The principle is to add a blow / charge nozzle to the air outlet of the original vacuum cleaner, thereby achieving the functions of vacuuming / extracting and blowing / charging.

[0003] Because the nozzle opening on the suction end is wider and the nozzle on the blowing end is narrower and longer, the intake and output volumes are both large during suction. To achieve a balance, the nozzle on the other side must be removed. If it is not removed, the suction power will be greatly weakened due to obstructed airflow. Similarly, when blowing / filling, the entire dust box with the suction / extraction nozzles must be removed because the filter inside the dust box will obstruct airflow, reducing the intake volume and preventing the formation of a high-pressure airflow during blowing, thus failing to achieve a good blowing / filling effect. Therefore, this "remove nozzle during suction, remove dust box during blowing" operation requires disassembling additional parts every time the working mode is switched, increasing the operation steps and affecting the ease of use.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0055] To make the objectives, technical solutions, and effects of this utility model clearer and more explicit, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0056] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0057] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. 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 utility model based on the specific circumstances.

[0058] Currently, when the device is in suction / extraction mode, the blow / charge nozzle on the other end needs to be removed; conversely, when in blow / charge mode, the dustbin section with the suction / extraction nozzle on the other end also needs to be removed. Due to normal operating requirements, the nozzle opening on the suction end is wider, while the nozzle on the blow end is narrower and longer. When suction is applied, both the intake and exhaust volumes are large; to achieve a balance, the blow nozzle on the other end must be removed. If it is not removed, the suction power will be significantly weakened due to obstructed airflow. Furthermore, from the product structure perspective, the blow nozzle is directly facing the face / body; if it is not removed, the air blown out from the nozzle will hit the face or body, creating a poor user experience. The compressed air at this point also has a certain temperature, which may cause harm over time. Conversely, during the blowing / inflating operation, the entire dust box with the suction / extraction nozzle must be removed, because the filter inside the dust box will obstruct airflow, reduce the air intake, and thus prevent the formation of a high-pressure airflow during blowing, resulting in poor blowing / inflating effects.

[0059] In view of the shortcomings of the prior art, this embodiment provides a structure for an integrated suction and blowing dust collector, which can be referred to as follows:

[0060] As attached Figure 1 and attached Figure 2 As shown, a dust collector integrating suction and blowing includes a dust collector body 1, a first air duct 11, a fan assembly 2, a dust suction assembly 3, a nozzle assembly 4, and an inlet / outlet assembly 5. The dust collector body 1 has a through-flow first air duct 11 inside for gas flow. The fan assembly 2 is located inside the first air duct 11 and serves as a driving source for airflow. The dust suction assembly 3 and the nozzle assembly 4 are respectively located at both ends of the dust collector body 1 to cooperate with the fan assembly 2 to achieve the functions of dust suction and air blowing. The inlet / outlet assembly 5 is located on the surface of the dust collector body 1. The inlet / outlet assembly 5 cooperates with the fan assembly 2 and can be used for exhaust when the dust suction assembly 3 is working, or for suction when the nozzle assembly 4 is working.

[0061] The dust collector body 1 has a first air duct 11 running along its axis, providing a channel for airflow. The fan assembly 2 is located in the middle of the first air duct 11. The side of the first air duct 11 near the dust collection assembly 3 forms a first air chamber, and the side of the first air duct 11 near the nozzle assembly 4 forms a second air chamber. The fan assembly 2 is fixed to the middle of the first air duct 11 by a bracket. The motor can rotate forward to drive the impeller to generate directional airflow, and its speed can be adjusted to adapt to different working requirements. The air inlet and outlet assembly 5 includes an air inlet 51, an air outlet 52, and a control component 53 for opening and closing the air inlet 51 and the air outlet 52. The control component 53 is used to coordinate with the working state of the dust collector to open and close the air inlet 51 and the air outlet 52. The air inlet 51 is located in the first air chamber, and one side of the air outlet 52 is connected to the air outlet channel 191, which is connected to the second air chamber.

[0062] Specifically, during vacuuming, the high-speed fan 22 inside the fan assembly 2 rotates forward, driving airflow into the vacuum assembly 3, through the first air duct 11, and out through the outlet 52 of the inlet / outlet assembly 5 and the nozzle assembly 4. At this time, the vacuum port of the vacuum assembly 3 generates a converging airflow to enhance suction, the dust cup collects the sucked-in impurities, and the clean airflow filtered by the filter is delivered through the first air duct 11 to the outlet 52 of the inlet / outlet assembly 5 and the nozzle assembly 4, allowing the airflow to be smoothly discharged, forming a complete vacuuming airflow circuit. Simultaneously, a small amount of airflow also flows out of the nozzle assembly 4. Because the outlet 52 of the inlet / outlet assembly 5 and the cross-section of the air duct on the outlet 52 are much larger than the outlet of the nozzle assembly 4, a large amount of airflow flows out through the inlet / outlet assembly 5. When switching to blowing operation, the high-speed fan 22 of the fan assembly 2 also rotates forward, and airflow is drawn in from the inlet 51 of the inlet / outlet assembly 5 and ejected from the nozzle assembly 4 through the first air duct 11. At this time, the air intake and exhaust assembly 5 is adjusted to the air intake state. External air enters the first air duct 11 through the air inlet 51 of the air intake and exhaust assembly 5. Under the drive of the fan, it forms a high-pressure airflow through the slender nozzle assembly 4 to meet the blowing or inflation needs, while also avoiding the influence of the filter 32 inside the dust collection assembly 3.

[0063] Compared to existing technologies, traditional integrated suction and blowing dust collectors require the disassembly of corresponding components when switching operating modes; otherwise, performance degradation will occur due to airflow obstruction. This solution, through the coordinated design of the first air duct 11 and the inlet / outlet air assembly 5, achieves mode switching without disassembling any components, solving the problem of cumbersome operation in traditional structures. Simultaneously, the inlet / outlet air path avoids obstruction of the blowing airflow by the filter element and the influence of the nozzle 42 on dust collection and exhaust, ensuring a stable and efficient airflow in both modes.

[0064] Through the above technical solution, this application not only ensures blowing / charging performance by drawing air through the air inlet / outlet assembly 5 to avoid obstruction by the dust box 33 filter element, ensuring sufficient air intake to form a high-pressure airflow, but also maintains the suction / extraction effect. The air inlet / outlet assembly 5 serves as an exhaust channel to achieve airflow balance, preventing suction attenuation without disassembling the nozzle 42. It effectively solves the problem of needing to disassemble parts for mode switching. Through the first air duct 11, the fan assembly 2, the dust / air nozzle assembly 4 fixed at both ends, and the switchable air inlet / outlet assembly 5, the mode can be switched without disassembly, improving convenience. At the same time, it also avoids safety and user experience issues. During suction / extraction, the airflow is mainly discharged from the air inlet / outlet assembly 5, and part of it is discharged through the nozzle assembly 4, thereby avoiding discomfort and injury caused by strong hot airflow blowing directly.

[0065] In this embodiment, as shown in the appendix Figure 1 Appendix Figure 4 Appendix Figure 5 and attached Figure 6As shown, the air inlet and outlet assembly 5 includes an air inlet 51, an air outlet 52, an air outlet channel 191, and a control component 53. The air inlet 51 is disposed on the surface of the dust collector body 1 to connect the first air duct 11 located on the side of the fan assembly 2 away from the nozzle assembly 4 with the outside, so that air can be drawn in from the air inlet 51 when the dust collector is blowing air. The air outlet 52 is disposed on the surface of the dust collector body 1, and the air outlet channel 191 is disposed inside the dust collector body 1. One end of the air outlet channel 191 is connected to the air outlet 52, and the other end is connected to the first air duct 11 located on the side of the fan assembly 2 near the nozzle assembly 4, so that the dust collector can perform main exhaust through the air outlet channel 191 and the air outlet 52 during the dust removal process, and perform secondary exhaust through the nozzle assembly 4. The control component 53 is slidably disposed inside the dust collector body 1, and the opening and closing of the air inlet 51 and the air outlet 52 can be controlled by moving the control component 53.

[0066] The air inlet 51 is located on the side wall surface of the dust collector body 1, and is located on the side of the fan assembly 2 away from the nozzle assembly 4. Its opening can be circular or square. When the air inlet 51 is open, it can directly connect the first air duct 11 on the side of the fan assembly 2 away from the nozzle assembly 4 with the outside air, providing a channel for airflow replenishment in the blowing / charging mode. The air outlet 52 is arranged at a certain angle to the air inlet 51 on the surface of the dust collector body 1. The opening area of ​​the air outlet 52 is slightly larger than that of the air inlet 51. The air outlet channel 191 is an independent channel opened inside the dust collector body 1. One end of it is sealed to the air outlet 52, and the other end is connected to the first air duct 11 on the side of the fan assembly 2 near the nozzle assembly 4, forming an independent exhaust path to facilitate the discharge of airflow.

[0067] The control component 53, as the core adjustment component of the air inlet and outlet assembly 5, adopts a slider structure design and is slidably assembled on the pre-set arc groove 12 inside the dust collector body 1. The length of the control component 53 is adapted to the distance between the air inlet 51 and the air outlet 52. The surface of the control component 53 is provided with a sealing plate that matches the shape of the air inlet 51 and the air outlet 52. When the dust collector switches to suction / extraction mode, the user can push the control component 53 to slide along the arc groove 12, so that the sealing plate on the control component 53 blocks the air inlet 51 and opens the air outlet 52. At this time, the fan assembly 2 drives the airflow from the dust collection assembly 3 into the first air duct 11. After passing through the fan assembly 2, the air is mainly discharged from the air outlet 52 through the air outlet channel 191 and secondarily discharged through the nozzle assembly 4, forming a complete dust collection and exhaust circuit. When switching to blowing / charging mode, the control component 53 is pushed in the opposite direction, and the sealing plate blocks the air outlet 52. The air inlet 51 is opened accordingly, and the outside air enters the first air duct 11 (the side of the fan assembly 2 away from the nozzle assembly 4) through the air inlet 51. Driven by the fan assembly 2, the air flows along the first air duct 11 to the nozzle assembly 4, forming a high-pressure blowing airflow, realizing the function of switching modes without disassembling the components.

[0068] Through the above technical solution, this application can switch modes without disassembling parts, improving convenience, and can also ensure the performance of the two modes (prevent suction attenuation and maintain high-pressure airflow). At the same time, it avoids hot airflow blowing directly on the human body and reduces the entry of impurities. Combined with low resistance and sealing design, it optimizes airflow efficiency and improves equipment safety, comfort and working efficiency.

[0069] In this embodiment, as shown in the appendix Figure 2 and attached Figure 7 As shown, the control component 53 includes a sliding plate 531, an inlet baffle 532, an outlet baffle 533, and an L-shaped push plate 534. The sliding plate 531 is slidably disposed inside the dust collector body 1. The inlet baffle 532 is disposed on the sliding plate 531 near the air inlet 51, and the outlet baffle 533 is disposed on the side of the sliding plate 531 near the outlet baffle 533. By sliding the sliding plate 531, the inlet baffle 532 and the outlet baffle 533 slide synchronously, so as to open the air inlet 51 and block the air outlet 52, or block the air inlet 51 and open the air outlet 52. The L-shaped push plate 534 is disposed on the surface of the sliding plate 531 and located on the surface of the dust collector body 1 to facilitate manual pushing of the sliding plate 531.

[0070] The sliding plate 531 has an arc-shaped structure that rotates around the circumference of the dust collector body 1. The sliding stroke is precisely controlled within the distance between the air inlet 51 and the air outlet 52 to ensure the accuracy of the switching action. The dimensions of the air inlet baffle 532 and the air outlet baffle 533 are slightly larger than the opening dimensions of the air inlet 51 and the air outlet 52. When the sliding plate 531 slides, the air inlet baffle 532 and the air outlet baffle 533 move synchronously with the sliding plate 531, forming a linkage mechanism. When the air inlet baffle 532 is completely detached from the air inlet 51, the air outlet baffle 533 just completely covers the air outlet 52, realizing the "air inlet 51 open, air outlet 52 blocked" blowing / charging mode. Conversely, when the air outlet baffle 533 is detached from the air outlet 52, the air inlet baffle 532 synchronously covers the air inlet 51, forming the "air inlet 51 blocked, air outlet 52 open" suction / extraction mode. The L-shaped push plate is also arranged in an arc shape and consists of a horizontal push plate and a vertical connecting column. One end of the vertical connecting column is fixed to the surface of the sliding plate 531 by screws or is designed as an integral part. The other end passes through the strip groove opened on the surface of the dust collector body 1 and is connected to the horizontal push plate. The surface of the horizontal push plate is provided with anti-slip texture and protrudes 3-5mm from the surface of the dust collector body 1 or is flush with it, so that users can push it with their fingers.

[0071] Compared to the existing technology where "the mouthpiece 42 needs to be removed for inhalation and the dust box 33 needs to be removed for blowing", this control component 53, through the mechanical linkage design of the sliding plate 531, only requires pushing the L-shaped push plate 534 to complete the mode switching. The operation steps are simplified from 3-4 steps to 1 step, and the switching time is shortened. In addition, the anti-slip design and ergonomic layout of the L-shaped push plate further improve the ease of operation, so that the elderly, children and other groups can easily complete the mode switching.

[0072] In this embodiment, as shown in the appendix Figure 5 As shown, the interior of the dust collector body 1 is provided with an arc groove 12, and the surface of the dust collector body 1 is provided with a stepped groove 13, which is connected to the arc groove 12. The L-shaped push plate 534 and the sliding plate 531 cooperate to form a slot with an opening. The sliding plate 531 is slidably disposed in the arc groove 12, and the L-shaped push plate 534 is slidably disposed in the stepped groove 13, so that the slot is engaged with the dust collector body 1, further restricting the movement of the sliding plate 531 in the radial direction of the dust collector body 1.

[0073] The arc groove 12 inside the dust collector body 1 extends axially, and the diameter of the arc is adapted to the thickness of the sliding plate 531, ensuring that the sliding plate 531 can fit tightly against the groove wall after being embedded. The stepped groove 13 on the surface of the dust collector body 1 is coaxially arranged with the arc groove 12 and is interconnected with it. The stepped groove 13 provides sliding space for the L-shaped push plate 534, and restricts its excessive indentation into the dust collector body 1 through the stepped surface. The cooperation structure between the L-shaped push plate 534 and the sliding plate 531 adopts a complementary design: the inner side of the vertical connecting column of the L-shaped push plate 534 and the surface of the sliding plate 531 are integrally formed, and the two together form a "U"-shaped groove with a lateral opening. The width of the groove is consistent with the wall thickness of the stepped groove 13 at the corresponding position of the dust collector body 1. During assembly, the sliding plate 531 is fully embedded in the arc groove 12, and its arc edge is completely in contact with the inner wall of the arc groove 12; the horizontal push plate of the L-shaped push plate 534 is located in the stepped groove 13, and the vertical connecting column passes through the connecting section between the stepped groove 13 and the arc groove 12, so that the "U" shaped slot is just locked on the side wall of the dust collector body 1. When the sliding plate 531 slides along the axial direction of the arc groove 12, the L-shaped push plate moves synchronously in the stepped groove 13, and the locking structure between the slot and the side wall of the body forms a radial constraint.

[0074] This application increases the contact area through the arc-shaped fitting design of the arc groove 12 and the sliding plate 531. Combined with the locking and limiting of the groove opening and the dust collector body 1, it fundamentally eliminates radial movement during the sliding process, ensuring that the air inlet baffle 532 and the air outlet baffle 533 are always accurately aligned with the air inlet 51 and the air outlet 52. The stepped structure of the stepped groove 13 not only provides sliding guidance for the L-shaped push plate 534, but also avoids the push plate from being excessively concave due to external pressure, thus extending the service life of the components. At the same time, the overall structure does not require additional fastening parts, and achieves stable fit through the self-constraint of the geometric shape, simplifying the assembly process and reducing the production and manufacturing costs.

[0075] In this embodiment, the appendix Figure 2 and attached Figure 3 As shown, the dust collector body 1 is provided with an air inlet sealing gasket 14 and an air outlet sealing gasket 15 inside. The air inlet sealing gasket 14 corresponds to the air inlet 51, is located on the inner wall of the first air duct 11, and cooperates with the air inlet baffle 532. The air outlet sealing gasket 15 corresponds to the air outlet 52, is located at the connection between the air outlet duct and the air outlet 52, and cooperates with the air outlet baffle 533.

[0076] Both the inlet sealing gasket 14 and the outlet sealing gasket 15 are made of EVA (ethylene-vinyl acetate copolymer). The inlet sealing gasket 14 is disposed on the inner wall of the first air duct 11, and has slots corresponding to the air inlet 51 to facilitate air intake when the air inlet 51 is open. The inlet sealing gasket 14 can be fixed with adhesive. The outlet sealing gasket 15 is disposed inside the dust collector body 1 and corresponds to the outlet duct. The outlet sealing gasket 15 has slots corresponding to the outlet channel 191. One side of the outlet sealing gasket 15 cooperates with the outlet baffle 533 to seal the outlet 52.

[0077] The air inlet 51 and the air outlet 52 can be sealed by the air inlet sealing gasket 14 and the air outlet sealing gasket 15, so as to prevent leakage from the air inlet 51 or the air outlet 52 when the dust collector is working, thereby affecting the dust collection or blowing operation of the dust collector.

[0078] In this embodiment, as shown in the appendix Figure 2As shown, the dust collector body 1 includes a battery pack assembly 16, a front body 17, a rear body 18, a first mounting plate 181, and an air duct bracket 19. The battery pack assembly 16 is cylindrical, including a cylindrical shell and a battery disposed within the cylindrical shell. The battery pack assembly 16 is a handheld part. The front body 17 is located on top of the battery pack assembly 16, and the air inlet 51 is located on the surface of the front body 17.
