[0002] This application relates to the field of cleaning equipment technology, and in particular to a handheld vacuum cleaner. [Background Technology]

[0003] With the development of intelligent manufacturing and communication technologies, more and more smart home devices are serving people's lives, bringing great convenience. Vacuum cleaners, as a tool for hygiene and cleaning, have become an indispensable smart home device in people's daily lives. Among them, handheld vacuum cleaners have the advantages of being small, portable, and easy to use, making them suitable for cleaning smaller spaces and popular with the public.

[0004] However, in order to adapt to various cleaning environments, handheld vacuum cleaners are usually equipped with multiple detachable accessories, which can lead to problems such as inconvenient storage and easy loss of accessories, thus failing to meet the needs.

[0005] [Summary of the Invention]

[0006] The main technical problem addressed by this application is to provide a handheld vacuum cleaner that improves the integration of the handheld vacuum cleaner and effectively enhances its applicability.

[0007] To address the aforementioned technical problems, this application provides a handheld vacuum cleaner comprising a main body, a brush component, and a drive component. The main body forms a suction channel with an open end. The brush component is slidably supported on the main body and disposed around the suction channel. The drive component is drively connected to the brush component, enabling the brush component to switch between a first state and a second state. In the first state, the brush component is at least partially exposed relative to the main body from the open end side; in the second state, the brush component is concealed within the main body.

[0008] The beneficial effects of this application are as follows: Unlike existing technologies, by configuring a device body, a brush component, and a drive component, the device body forms a suction channel with an open end. The brush component is slidably supported on the device body and positioned around the suction channel. The drive component allows the brush component to switch between a first state and a second state. In the first state, the brush component is at least partially exposed from the open end relative to the device body to assist the handheld vacuum cleaner in cleaning the external environment. In the second state, the brush component is hidden inside the device body. By switching between the first and second states, the brush component is integrated as part of the handheld vacuum cleaner, effectively improving its integration. The brush component can be used and stored without additional installation or removal from the handheld vacuum cleaner. When the brush component is needed, it switches to the first state, exposing at least partially from the open end; when not needed, it switches to the second state, hiding the brush component inside the device body. This effectively improves the ease of use and applicability of the handheld vacuum cleaner. [Attached Image Description]

[0021] With the development of intelligent manufacturing and communication technologies, more and more smart home devices are serving people's lives, bringing great convenience. Vacuum cleaners, as a tool for hygiene and cleaning, have become an indispensable smart home device in people's daily lives. There are many types of vacuum cleaners, including canister, upright, and handheld vacuum cleaners. Among them, handheld vacuum cleaners have the advantages of being compact, portable, and easy to use, making them suitable for cleaning smaller spaces and popular with the public.

[0022] Through long-term research, the inventors of this application have discovered that current handheld vacuum cleaners are typically used to clean small areas such as car interiors, keyboards, desktops, and beds. However, in actual use, these environments are complex and have many hard-to-reach areas, requiring different cleaning methods for different areas. Related technologies often equip handheld vacuum cleaners with multiple detachable and replaceable accessories of different models to handle complex cleaning environments. Examples include extended hoses for sucking up debris in small spaces and brushes for cleaning crevices. However, multiple detachable accessories occupy excessive storage space, creating a storage burden for users. Furthermore, different accessories need to be disassembled and replaced each time, resulting in low integration and inconvenience for handheld vacuum cleaners. Therefore, this application proposes the following embodiments to solve the above-mentioned technical problems.

[0023] The following embodiments of this application describe an exemplary structure of a handheld vacuum cleaner.

[0024] As shown in Figure 1, the handheld vacuum cleaner 1 includes a main body 10, a brush component 20, and a drive component 80.

[0025] The main body 10 of the device is used to clean the environment to be cleaned under the operation of the user. A fan is installed inside the main body 10 to provide airflow. The airflow provided by the fan is, for example, the amount of air flowing through the fan per unit time. The greater the airflow, the more air containing debris is sucked in by the handheld vacuum cleaner 1 per unit time. Under the action of the airflow provided by the fan directed into the main body 10 of the device, the handheld vacuum cleaner 1 will suck in air containing debris, thereby achieving the purpose of cleaning.

[0026] As shown in Figures 1 to 4, the main body 10 of the device forms a suction channel 102 with an open end 101. The airflow provided by the fan allows air from the external environment to be cleaned to enter the suction channel 102 through the open end 101 and then flow into the interior of the main body 10. A brush component 20 is slidably supported on the main body 10 and positioned around the suction channel 102 to reduce the possibility of the brush component 20 affecting the airflow within the suction channel 102. A drive component 80 is connected to the brush component 20 to allow the brush component 20 to switch between a first state and a second state. In the first state, the brush component 20 is at least partially exposed relative to the main body 10 from the open end 101 side; in the second state, the brush component 20 is hidden inside the main body 10.

[0027] By incorporating a brush component 20 that can switch between a first state and a second state, the brush component 20 is integrated as part of the handheld vacuum cleaner 1, effectively improving the integration of the handheld vacuum cleaner 1. The brush component 20 can be used and stored without requiring additional installation or removal from the handheld vacuum cleaner 1. When the brush component 20 is needed, the first state is switched to expose at least part of it from the opening end 101, allowing for cleaning of the external environment. When the brush component 20 is not needed, the second state is switched to hide it inside the main body 10. This ensures that the use of the handheld vacuum cleaner 1 is not affected without removing the brush component 20, and the brush component 20 is not visible from the outside of the handheld vacuum cleaner 1. This improves the aesthetics and ease of use of the handheld vacuum cleaner 1, effectively enhancing its applicability.

[0028] Optionally, as shown in Figures 2 to 6, the handheld vacuum cleaner 1 also includes a duct 30. The duct 30 is detachably inserted into the suction channel 102 through the open end 101. When the duct 30 is inserted into the suction channel 102, the duct 30 constitutes part of the drive member 80. The duct 30 pushes the brush 20 to slide into the device body 10, so that the brush 20 switches from a first state to a second state. When the duct 30 is disengaged from the suction channel 102, the drive member 80 is used to enable the brush 20 to switch from the second state to the first state. When the user needs to use the air duct 30 to assist the handheld vacuum cleaner 1 in cleaning the environment, and does not need to use the brush 20, the brush 20 is pushed into the main body 10 by inserting the air duct 30 into the suction channel 102. This allows the brush 20 to switch from a first state to a second state without disassembling it, thus reducing the storage difficulty for the user. Furthermore, by sliding the brush 20 into the device to hide it, the user is prevented from seeing the exposed brush 20 from the outside of the handheld vacuum cleaner 1, improving its aesthetics. In addition, the switching of the brush 20's state can be achieved simultaneously with the installation of the air duct 30, making the operation convenient and quick, improving the ease of use and applicability of the handheld vacuum cleaner 1.

[0029] Optionally, as shown in FIG4, the brush component 20 includes a plurality of bristle portions 240 circumferentially spaced at one end of the brush component 20 along the suction channel 102. In the first state, the plurality of bristle portions 240 are at least partially exposed from the opening end 101 side relative to the device body 10, so that the user can use the plurality of bristle portions 240 to clean up debris in narrow spaces, such as the angle inside a car, the gap between a table and a wall, etc.

[0030] Optionally, as shown in Figures 4 and 6, the main body 10 of the device includes an outer shell 110 and an inner shell 120. The inner shell 120 forms a dust suction channel 102. The outer shell 110 covers the outside of the inner shell 120. The brush member 20 is sandwiched between the outer shell 110 and the inner shell 120 and is slidably supported on the inner shell 120. In the second state, the brush member 20 is hidden inside the outer shell 110. Specifically, a gap 106 is formed between the outer shell 110 and the inner shell 120, and the brush member 20 is disposed within the gap 106. By configuring the main body 10 of the device to include an outer shell 110 and an inner shell 120, and placing the brush 20 between the outer shell 110 and the inner shell 120, while the inner shell 120 forms a suction channel 102, the brush 20 is effectively isolated from the suction channel 102 while making it easy to hide. This effectively reduces the possibility that the brush 20 will affect the air flowing in the suction channel 102, which is conducive to improving the reliability and effectiveness of the handheld vacuum cleaner 1.

[0031] Optionally, as shown in Figures 4 and 6, the inner housing 120 has a limiting hole 103 communicating with the suction channel 102, and the brush component 20 is provided with a first limiting part 210, which extends into the suction channel 102 through the limiting hole 103. The air duct 30 includes a second limiting part 330. When the air duct 30 is inserted into the suction channel 102, the second limiting part 330 abuts against the first limiting part 210 and pushes the brush component 20 to slide relative to the inner housing 120. The limiting hole 103 can be, for example, a strip-shaped hole, and the first limiting part 210 can slide within the limiting hole 103. The length of the limiting hole 103 is the range of length within which the brush component 20 can slide relative to the inner housing 120. In some embodiments, the length direction of the limiting hole 103 is parallel to the axial direction of the suction channel 102, thereby allowing the brush 20 to slide relative to the inner housing 120 along the axial direction of the suction channel 102. This improves the smoothness of the sliding of the brush 20 relative to the inner housing 120 and effectively reduces the obstruction of the opening end 101 of the suction channel 102 by the brush 20. It also effectively reduces the possibility that the brush 20 will affect the air flowing in the suction channel 102, and effectively improves the reliability and effectiveness of the handheld vacuum cleaner 1.

[0032] Optionally, as shown in Figure 6, the duct 30 includes a first tube body 310 and a second tube body 320. The diameter of the first tube body 310 is smaller than that of the second tube body 320, and a second limiting portion 330 is formed at the connection between the first tube body 310 and the second tube body 320. When the duct 30 is inserted into the suction channel 102, the first tube body 310 is accommodated within the suction channel 102, and at least a portion of the second tube body 320 is exposed outside the main body 10 of the device. The first tube body 310 and the second tube body 320 can be connected by welding or bonding, or they can be integrally formed, or other connection methods can be used. In some embodiments, the first tube body 310 and the second tube body 320 are integrally formed, which effectively improves the sealing performance at the connection between the first tube body 310 and the second tube body 320, facilitates smooth airflow within the duct 30, and improves the reliability of the handheld vacuum cleaner 1 in sucking up debris using the duct 30.

[0033] By setting a first tube 310 and a second tube 320 with different diameters to form a second limiting part 330, there is no need to set an additional structure for abutting the first limiting part 210, which effectively simplifies the structure of the air duct 30 and effectively reduces the production cost of the air duct 30. In addition, when the air duct 30 is inserted into the dust suction channel 102, the first tube 310 with a smaller diameter enters the dust suction channel 102 first, which helps to reduce the difficulty of inserting the air duct 30 into the dust suction channel 102 and improves the convenience of inserting the air duct 30 into the dust suction channel 102.

[0034] Optionally, as shown in Figures 4 and 6, the driving component 80 includes an elastic element 40, which elastically biases the brush component 20 so that when the air duct 30 disengages from the suction channel 102, the brush component 20 switches from a second state to a first state. Specifically, when the brush component 20 switches from the first state to the second state, it slides into the device body 10 due to the abutment of the air duct 30, causing the elastic element 40 to elastically deform. When the brush component 20 switches from the second state to the first state, the elastic element 40 elastically resets to push the brush component 20 to slide outward from the opening end 101, so that the brush component 20 is at least partially exposed relative to the device body 10 from the opening end 101 side. By setting the elastic element 40 to achieve the switching of the brush component 20 from the second state to the first state, the structure is simple and effective, and the switching can be completed without additional operation by the user, making it convenient to use and improving the ease of use of the handheld vacuum cleaner 1. In some embodiments, the drive component 80 may also include other structures such as a hydraulic mechanism and a lead screw mechanism to enable the brush component 20 to slide relative to the device body 10, thereby enabling the brush component 20 to switch between a first state and a second state.

[0035] Optionally, as shown in Figure 7, a protrusion 122 is provided on the outer wall surface of the inner shell 120. A receiving groove 104 is provided on the protrusion 122, and the elastic member 40 is embedded in the receiving groove 104 to limit the elastic member 40. The protrusion 122 is also provided with an opening 105 connecting the receiving groove 104 and the outside of the protrusion 122. The brush member 20 is provided with an abutting block 230. The abutting block 230 elastically abuts against the elastic member 40 through the opening 105. When the brush member 20 switches from the first state to the second state, the abutting block 230 extends into the receiving groove 104 through the opening 105 to abut against the elastic member 40 and cause elastic deformation.

[0036] Optionally, as shown in Figure 7, the brush component 20 is provided with a first snap-fit ​​structure 220, and the inner housing 120 is provided with a second snap-fit ​​structure 121 that cooperates with the first snap-fit ​​structure 220. The first snap-fit ​​structure 220 and the second snap-fit ​​structure 121 are slidably connected, so that the brush component 20 can slide relative to the inner housing 120 along the axial direction of the suction channel 102 and be held on the inner housing 120 along the radial direction of the suction channel 102. This is beneficial to improving the stability of the sliding of the brush component 20 and the stability and reliability of the switching between the first and second states of the brush component 20. In some embodiments, there are two of each of the first snap-fit ​​structure 220 and the second snap-fit ​​structure 121. The two first snap-fit ​​structures 220 are symmetrically arranged on both sides of the brush component 20, and the two second snap-fit ​​structures 121 are symmetrically arranged on both sides of the inner housing 120. This further improves the stability of the connection between the brush component 20 and the inner housing 120 and the stability of the sliding of the brush component 20, thereby improving the stability and reliability of the switching between the first and second states of the brush component 20.

[0037] Optionally, as shown in Figure 2, the handheld vacuum cleaner 1 includes a cover 50 surrounding the air duct 30. When the air duct 30 is inserted into the suction channel 102, the cover 50 is used to seal the gap 106 between the outer shell 110 and the inner shell 120 and to cover the brush 20, thereby effectively blocking moisture and dust in the external environment, effectively reducing the possibility of moisture and dust entering the gap 106, which helps to improve the sealing between the outer shell 110 and the inner shell 120, and helps to improve the service life of the handheld vacuum cleaner 1.

[0038] Optionally, as shown in Figures 1 and 2, the handheld vacuum cleaner 1 includes a handheld component 60 for a user to grip and operate the handheld vacuum cleaner 1. The handheld component 60 has a center line L1 along which it extends. The center line L1 is determined by the shape of the handheld component 60 and can be a straight line, a curve, or a combination of both. The handheld component 60 is connected to the device body 10, which can be a fixed connection or a movable connection, such as a rotating connection, a sliding connection, or a detachable connection. Alternatively, the handheld component 60 and the outer shell 110 of the device body 10 can be integrally formed. In some embodiments, as shown in Figures 1 and 2, the centerline L1 of the handheld component 60 is a straight line. The handheld component 60 is fixedly connected to the side of the device body 10 away from the opening end 101. That is, the handheld component 60 and the suction channel 102 are located at opposite ends of the handheld vacuum cleaner 1, so that when the handheld component 60 is gripped, the brush component 20 or the air duct 30 can be supported in front of the user, making it convenient for the user to operate the handheld vacuum cleaner 1.

[0039] Optionally, as shown in Figures 1 and 2, the handheld vacuum cleaner 1 further includes a switch assembly 70. The switch assembly 70 is operated by the user to control the functions of the handheld vacuum cleaner 1, such as turning it on, off, switching modes, pausing, etc. The switch assembly 70 is disposed on the outer wall surface of the device body 10 near the handheld component 60, so that when the user holds and uses the handheld vacuum cleaner 1, the switch assembly 70 is as close as possible to the user's hand, making it convenient for the user to operate the switch assembly 70 while gripping the handheld component 60 to control the handheld vacuum cleaner 1 to achieve the corresponding functions.

[0040] In some embodiments, the handheld vacuum cleaner 1 includes a power supply battery that powers the handheld vacuum cleaner 1, enabling wireless use and improving its convenience and applicability. The power supply battery includes, but is not limited to, lithium-ion batteries, sodium-ion batteries, sodium-lithium-ion batteries, lithium metal batteries, sodium metal batteries, lithium-sulfur batteries, magnesium-ion batteries, nickel-metal hydride batteries, nickel-cadmium batteries, lead-acid batteries, etc. The power supply battery can be cylindrical, flat, cuboid, or other shapes. The power supply battery can be a single battery or multiple batteries, which can be connected in series, parallel, or a combination thereof. A combination connection means that multiple batteries are connected in both series and parallel configurations, and can be directly connected in series, parallel, or a combination thereof. Alternatively, the power supply battery can be composed of multiple batteries first connected in series, parallel, or a combination thereof to form a battery module, and then these battery modules can be connected in series, parallel, or a combination thereof to form a whole. The power supply battery may also include other structures; for example, it may include a busbar component for electrical connection between multiple batteries. At least a portion of the power supply battery can be housed within the handheld component 60. By housing the power supply battery within the internal space of the handheld component 60, the overall size of the handheld vacuum cleaner 1 can be reduced, making the handheld vacuum cleaner 1 more compact and improving its integration and portability.

[0041] The following provides a detailed explanation of the process by which the brush component 20 switches between the first and second states.

[0042] As shown in Figure 4, when the brush component 20 is in the first state, the air duct 30 is detached from the main body 10, the gap 106 between the outer shell 110 and the inner shell 120 is not sealed, and the first limiting part 210 of the brush component 20 abuts against the limiting hole 103 of the inner shell 120 near the opening end 101, and extends into the suction channel 102 through the limiting hole 103. The bristles 240 of the brush component 20 are at least partially exposed from the opening end 101 relative to the main body 10 to assist the handheld vacuum cleaner 1 in cleaning the external environment.

[0043] As shown in Figures 4, 6, and 7, when the duct 30 is inserted into the suction channel 102 from the opening end 101, the first pipe body 310 and the second pipe body 320 of the duct 30 are sequentially inserted into the suction channel 102, and the duct 30... During insertion, the second limiting part 330 of the air duct 30 abuts against the first limiting part 210 and pushes the first limiting part 210 to slide within the limiting hole 103, thereby causing the brush part 20 to slide into the device body 10. The first snap-fit ​​structure 220 slides relative to the second snap-fit ​​structure 121. The abutting block 230 of the brush part 20 extends from the opening 105 into the receiving groove 104 to abut against the elastic member 40, causing the elastic member 40 to undergo elastic deformation until the brush part 20 is covered by the outer shell 110 and hidden inside the device body 10. The brush part 20 switches from the first state to the second state. At this time, the first tube 310 is accommodated in the dust suction channel 102, and at least a portion of the second tube 320 is exposed outside the device body 10.

[0044] As shown in Figure 6, when the brush part 20 is in the second state, the air duct 30 is inserted into the suction channel 102, the cover 50 covers the gap 106 between the outer shell 110 and the inner shell 120, and covers the brush part 20. The brush part 20 cannot be seen from the outside of the handheld vacuum cleaner 1. The second limiting part 330 abuts against the first limiting part 210, the abutting block 230 abuts against the elastic member 40, and the elastic member 40 undergoes elastic deformation.

[0045] As shown in Figures 4, 6, and 7, when the duct 30 disengages from the suction channel 102, the second tube 320 and the first tube 310 disengage from the suction channel 102 in sequence. The elastic element 40 in the receiving groove 104 elastically resets to push the abutment block 230 to slide towards the outside of the opening end 101, thereby causing the brush 20 to slide relative to the inner shell 120. The first snap-fit ​​structure 220 slides relative to the second snap-fit ​​structure 121. The first limiting part 210 slides in the limiting hole 103 until the first limiting part 210 abuts against the edge of the limiting hole 103. The brush 20 is at least partially exposed from one side of the opening end 101 relative to the main body of the equipment. The brush 20 switches from the second state to the first state.

[0046] By setting up a device body 10 and a brush component 20, wherein the device body 10 forms a suction channel 102 with an open end 101, the brush component 20 is slidably supported on the device body 10 and is set on the outer ring of the suction channel 102, and the brush component 20 can switch between a first state and a second state. In the first state, the brush component 20 is at least partially exposed from the open end 101 side relative to the device body 10 to assist the handheld vacuum cleaner 1 in cleaning the external environment, while in the second state, the brush component 20 is hidden inside the device body 10. By switching between the first and second states of the brush component 20, the brush component 20 is integrated as part of the handheld vacuum cleaner 1, effectively improving the integration of the handheld vacuum cleaner 1. The brush component 20 can be used and stored without the need to be installed or removed from the handheld vacuum cleaner 1. When the brush component 20 is needed, it is switched to the first state so that the brush component 20 is at least partially exposed from the opening end 101. When the brush component 20 is not needed, it is switched to the second state to hide the brush component 20 inside the main body 10 of the device, effectively improving the ease of use of the handheld vacuum cleaner 1 and enhancing its applicability.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them.
