[0028] With the development of intelligent manufacturing technology and communication technology, more and more smart home devices serve people's lives and bring great convenience to people's lives. Vacuum cleaners, as a tool for sanitation and cleaning, have become an indispensable smart home device in people's daily lives. There are many types of vacuum cleaners, including horizontal, vertical, handheld and other types. Among them, handheld vacuum cleaners have the advantages of small size, easy to carry and simple to use. They are suitable for cleaning smaller spaces and are popular with the public.

[0029] After long-term research, the inventor of the present application found that current handheld vacuum cleaners are usually used to clean small environments such as car interiors, keyboards, desktops, beds, etc., and in actual use, due to the complexity of these environments to be cleaned and the many sanitary dead corners, different cleaning methods need to be adopted for different areas when cleaning. In the related art, a handheld vacuum cleaner is usually equipped with a plurality of detachable and replaceable accessories of different models to cope with complex cleaning environments, such as an extended air duct for sucking garbage objects in a small space, and a brush for cleaning gaps, etc., but multiple detachable accessories will take up too much storage space, causing a storage burden on the user, and different accessories need to be disassembled and replaced each time they are used. The handheld vacuum cleaner is not highly integrated and is very inconvenient to use. Based on this, the present application proposes the following embodiments to solve the above technical problems.

[0030] The following embodiments of the present application describe an exemplary structure of a handheld vacuum cleaner.

[0031] like Figure 1 As shown, the handheld vacuum cleaner 1 includes a device body 10 , a brush member 20 and a driving member 80 .

[0032] The device body 10 is used to clean the environment to be cleaned under the control of the user. A fan is arranged inside the device body 10, and the fan is used to provide air volume. The air volume provided by the fan is, for example, the amount of air flowing through the fan per unit time. The greater the air volume, the more air containing garbage objects will be sucked in by the handheld vacuum cleaner 1 per unit time. Under the action of the air volume directed to the inside of the device body 10 provided by the fan, the handheld vacuum cleaner 1 will suck in air containing garbage objects, thereby achieving the purpose of cleaning.

[0033] like Figures 1 to 4As shown, the device body 10 is used to form a dust collection channel 102 with an open end 101. The air volume provided by the fan allows the air in the external environment to be cleaned to enter the dust collection channel 102 through the open end 101, and then flow to the inside of the device body 10 through the dust collection channel 102. The brush member 20 is slidably supported on the device body 10 and is arranged on the periphery of the dust collection channel 102 to reduce the possibility that the brush member 20 affects the air flowing in the dust collection channel 102. The driving component 80 is transmission-connected to the brush member 20 so that the brush member 20 can switch between a first state and a second state, wherein in the first state, the brush member 20 is at least partially exposed from the side of the open end 101 relative to the device body 10, and in the second state, the brush member 20 is hidden inside the device body 10.

[0034] By providing a brush member 20 that can be switched between a first state and a second state, the brush member 20 is used as an integral part of the handheld vacuum cleaner 1, thereby effectively improving the integration of the handheld vacuum cleaner 1. The brush member 20 can be used and stored without additionally installing or removing the brush member 20 from the handheld vacuum cleaner 1. When the brush member 20 is needed, it is switched to the first state so that the brush member 20 is at least partially exposed from one side of the opening end 101, so that the exposed brush member 20 can be used to clean the external environment to be cleaned. When the brush member 20 is not needed, it is switched to the second state so that the brush member 20 is hidden inside the device body 10, so that the use of the handheld vacuum cleaner 1 will not be affected if the brush member 20 is not removed, and the brush member 20 cannot be seen from the outside of the handheld vacuum cleaner 1, which is beneficial to improving the aesthetics of the handheld vacuum cleaner 1, and improving the ease of use of the handheld vacuum cleaner 1, and effectively improving the applicability of the handheld vacuum cleaner 1.

[0035] Alternatively, if Figures 2 to 6As shown, the handheld vacuum cleaner 1 also includes an air duct 30, which is detachably inserted into the dust suction channel 102 through the open end 101. When the air duct 30 is inserted into the dust suction channel 102, the air duct 30 constitutes a part of the driving component 80. The air duct 30 pushes the brush member 20 to slide toward the inside of the device body 10 so that the brush member 20 switches from the first state to the second state. When the air duct 30 is separated from the dust suction channel 102, the driving component 80 is used to enable the brush member 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 to be cleaned, and does not need to use the brush member 20, the air duct 30 is inserted into the dust suction channel 102 to push the brush member 20 to slide into the inside of the device body 10, so that the brush member 20 completes the switch from the first state to the second state, and the brush member 20 can be stored and hidden without disassembling the brush member 20, which is conducive to reducing the storage difficulty of the user, and the brush member 20 is hidden by sliding the brush member 20 into the inside of the device to avoid the user from seeing the exposed brush member 20 from the outside of the handheld vacuum cleaner 1, which is conducive to improving the aesthetics of the handheld vacuum cleaner 1. In addition, the brush member 20 is pushed by the air duct 30 to achieve switching, and the state of the brush member 20 can be switched while the air duct 30 is installed, which is convenient and quick to operate, which is conducive to improving the convenience of use of the handheld vacuum cleaner 1 and effectively improving the applicability of the handheld vacuum cleaner 1.

[0036] Alternatively, if Figure 4 As shown, the brush member 20 includes a plurality of bristle portions 240 arranged at one end of the brush member 20 at circumferential intervals along the dust suction channel 102. In a first state, the plurality of bristle portions 240 are at least partially exposed from the side of the opening end 101 relative to the device body 10, so that the user can use the plurality of bristle portions 240 to clean garbage objects in narrow spaces, such as the angles inside a car, the gaps between a table and a wall, etc.

[0037] Alternatively, if Figure 4 and Figure 6As shown, the device body 10 includes an outer shell 110 and an inner shell 120, the inner shell 120 is used to form a dust suction channel 102, the outer shell 110 is covered on the outside of the inner shell 120, and 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 in 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 arranged in the gap 106. By configuring the device body 10 to include an outer shell 110 and an inner shell 120, and configuring the brush member 20 between the outer shell 110 and the inner shell 120, and forming a dust suction channel 102 in the inner shell 120, the brush member 20 can be effectively isolated from the dust suction channel 102 while being convenient to hide, thereby effectively reducing the possibility of the brush member 20 affecting the air circulating in the dust suction channel 102, which is beneficial to improving the reliability and effectiveness of the handheld vacuum cleaner 1.

[0038] Alternatively, if Figure 4 and Figure 6 As shown, the inner shell 120 is provided with a limiting hole 103 connected to the dust suction channel 102, and the brush member 20 is provided with a first limiting portion 210, and the first limiting portion 210 extends into the dust suction channel 102 through the limiting hole 103. The air duct 30 includes a second limiting portion 330. When the air duct 30 is inserted into the dust suction channel 102, the second limiting portion 330 abuts against the first limiting portion 210 and pushes the brush member 20 to slide relative to the inner shell 120. The limiting hole 103 can be, for example, a bar-shaped hole, and the first limiting portion 210 can slide in the limiting hole 103. The length of the limiting hole 103 is the length range in which the brush member 20 can slide relative to the inner shell 120. In some embodiments, the length direction of the limiting hole 103 is parallel to the axial direction of the dust suction channel 102, so that the brush member 20 can slide relative to the inner shell 120 along the axial direction of the dust suction channel 102, which is beneficial to improve the smoothness of the sliding of the brush member 20 relative to the inner shell 120, and effectively reduce the obstruction of the opening end 101 of the dust suction channel 102 by the brush member 20, effectively reduce the possibility of the brush member 20 affecting the air circulating in the dust suction channel 102, and effectively improve the reliability and effectiveness of the handheld vacuum cleaner 1.

[0039] Alternatively, if Figure 6As shown, the air 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 the second tube body 320, and the connection between the first tube body 310 and the second tube body 320 forms a second limiter 330. When the air duct 30 is inserted into the dust suction channel 102, the first tube body 310 is accommodated in the dust suction channel 102, and at least part of the second tube body 320 is used to be exposed outside the device body 10. The first tube body 310 and the second tube body 320 can be connected by welding or bonding, or the first tube body 310 and the second tube body 320 can be integrally formed, and of course other connection methods can also be used. In some embodiments, the first tube body 310 and the second tube body 320 are integrally formed, which effectively improves the sealing of the connection between the first tube body 310 and the second tube body 320, facilitates the smooth circulation of air in the air duct 30, and is conducive to improving the reliability of the handheld vacuum cleaner 1 using the air duct 30 to suck garbage objects.

[0040] By providing a first tube body 310 and a second tube body 320 having different diameters to form a second limiting portion 330, there is no need to additionally provide a structure for abutting the first limiting portion 210, thereby effectively simplifying the structure of the air duct 30 and effectively reducing the production cost of the air duct 30. In addition, in the process of inserting the air duct 30 into the dust suction channel 102, the first tube body 310 having a smaller diameter enters the dust suction channel 102, which helps to reduce the difficulty of inserting the air duct 30 into the dust suction channel 102 and helps to improve the convenience of inserting the air duct 30 into the dust suction channel 102.

[0041] Alternatively, if Figure 4 and Figure 6 As shown, the driving member 80 includes an elastic member 40, and the elastic member 40 is used to elastically bias the brush member 20, so that when the air duct 30 is separated from the dust collection channel 102, the brush member 20 switches from the second state to the first state. Specifically, when the brush member 20 switches from the first state to the second state, the brush member 20 is abutted by the air duct 30 to slide toward the inside of the device body 10, so that the elastic member 40 is elastically deformed, and when the brush member 20 switches from the second state to the first state, the elastic member 40 elastically resets to push the brush member 20 to slide toward the outside of the opening end 101, so that the brush member 20 is at least partially exposed from the side of the opening end 101 relative to the device body 10. By setting the elastic member 40 to realize the switching of the brush member 20 from the second state to the first state, the structure is simple and effective, and the switching can be completed without the user performing additional operations. It is easy to use and is conducive to improving the convenience of use of the handheld vacuum cleaner 1. In some embodiments, the driving member 80 may further include other structures such as a hydraulic mechanism and a screw mechanism to enable the brush member 20 to slide relative to the device body 10, thereby enabling the brush member 20 to switch between the first state and the second state.

[0042] Alternatively, if Figure 7As shown, a protrusion 122 is provided on the outer wall surface of the inner shell 120, and a receiving groove 104 is provided on the protrusion 122. 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 abutment block 230, and the abutment 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 abutment block 230 extends into the receiving groove 104 through the opening 105 to abut against the elastic member 40 to cause elastic deformation.

[0043] Alternatively, if Figure 7 As shown, the brush member 20 is provided with a first buckle structure 220, and the inner shell 120 is provided with a second buckle structure 121 that cooperates with the first buckle structure 220. The first buckle structure 220 and the second buckle structure 121 are slidably connected, so that the brush member 20 can slide relative to the inner shell 120 along the axial direction of the dust suction channel 102, and remain on the inner shell 120 along the radial direction of the dust suction channel 102, which is conducive to improving the sliding stability of the brush member 20, and is conducive to improving the stability and reliability of the switching of the brush member 20 between the first state and the second state. In some embodiments, the number of the first buckle structure 220 and the second buckle structure 121 is two, the two first buckle structures 220 are symmetrically arranged on both sides of the brush member 20, and the two second buckle structures 121 are symmetrically arranged on both sides of the inner shell 120, thereby further improving the stability of the connection between the brush member 20 and the inner shell 120 and the sliding stability of the brush member 20, and further facilitating the improvement of the stability and reliability of the switching of the brush member 20 between the first state and the second state.

[0044] Alternatively, if Figure 2 As shown, the handheld vacuum cleaner 1 includes a cover body 50 arranged around the periphery of the air duct 30. When the air duct 30 is inserted into the dust suction channel 102, the cover body 50 is used to seal the gap 106 between the outer shell 110 and the inner shell 120, and to cover the brush member 20, thereby effectively shielding water vapor and dust in the external environment, effectively reducing the possibility of water vapor and dust entering the gap 106, which is beneficial to improving the sealing between the outer shell 110 and the inner shell 120, and is beneficial to improving the service life of the handheld vacuum cleaner 1.

[0045] Alternatively, if Figure 1 and Figure 2As shown, the handheld vacuum cleaner 1 includes a handheld piece 60, and the handheld piece 60 is used for the user to grasp. The user grasps the handheld vacuum cleaner 1 to operate the handheld vacuum cleaner 1. The handheld piece 60 has a center line L1, and the handheld piece 60 extends along the center line L1. The center line L1 is determined by the shape of the handheld piece 60, and can be a straight line, a curve, or a combination of a curve and a straight line. The handheld piece 60 is connected to the device body 10, and can be fixedly connected or movably connected, such as a rotating connection, a sliding connection, or a detachable connection, etc. Of course, the handheld piece 60 and the outer shell 110 of the device body 10 can also be integrally formed. In some embodiments, such as Figure 1 and Figure 2 As shown, the center line L1 of the handpiece 60 is a straight line, and the handpiece 60 is fixedly connected to the side of the device body 10 away from the opening end 101, that is, the handpiece 60 and the dust suction channel 102 are respectively located at opposite ends of the handheld vacuum cleaner 1, so that when the handpiece 60 is grasped, the brush part 20 or the air duct 30 can be supported in front of the user, which is convenient for the user to operate the handheld vacuum cleaner 1.

[0046] Alternatively, if Figure 1 and Figure 2 As shown, the handheld vacuum cleaner 1 further includes a switch assembly 70, which is used for the user to operate to realize the function control of the handheld vacuum cleaner 1, such as turning on, off, switching modes, pausing, etc. The switch assembly 70 is arranged on the outer wall surface of the device body 10 on the side close to the handpiece 60, so that when the user holds the handheld vacuum cleaner 1, the switch assembly 70 is as close to the user's hand as possible, so that the user can operate the switch assembly 70 while holding the handpiece 60 to control the handheld vacuum cleaner 1 to realize the corresponding function.

[0047] In some embodiments, the handheld vacuum cleaner 1 includes a power supply battery, which is used to power the handheld vacuum cleaner 1 to achieve wireless use of the handheld vacuum cleaner 1, thereby improving the convenience and applicability of the handheld vacuum cleaner 1. 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-hydrogen batteries, nickel-cadmium batteries, lead-acid batteries, etc. The power supply battery may be cylindrical, flat, rectangular or in other shapes. The power supply battery may be a single battery or multiple batteries, and the multiple batteries may be connected in series, in parallel or in mixed connection. Mixed connection means that multiple batteries are both connected in series and in parallel, and multiple batteries may be directly connected in series, in parallel or in mixed connection. Of course, the power supply battery may also be a battery module formed by connecting multiple batteries in series, in parallel or in mixed connection, and then connecting multiple battery modules in series, in parallel or in mixed connection to form a whole. The power supply battery may also include other structures. For example, the power supply battery may also include a converging component for realizing electrical connection between multiple batteries. At least part of the power supply battery can be set in the handheld piece 60. By setting at least part of the power supply battery in the handheld piece 60 and using the internal space of the handheld piece 60 to accommodate the power supply battery, the overall volume of the handheld vacuum cleaner 1 can be reduced, making the handheld vacuum cleaner 1 more compact, which is conducive to improving the integration and portability of the handheld vacuum cleaner 1.

[0048] The process of switching the brush member 20 between the first state and the second state is described in detail below.

[0049] like Figure 4 As shown, when the brush member 20 is in the first state, the air duct 30 is separated from the device body 10, the gap 106 between the outer shell 110 and the inner shell 120 is not covered, and the first limiting portion 210 of the brush member 20 abuts against the side of the limiting hole 103 of the inner shell 120 close to the opening end 101, and extends into the dust suction channel 102 through the limiting hole 103. The bristle portion 240 of the brush member 20 is at least partially exposed from the side of the opening end 101 relative to the device body 10 to assist the handheld vacuum cleaner 1 in cleaning the external environment.

[0050] like Figure 4 , Figure 6 and Figure 7As shown, when the air duct 30 is inserted into the dust suction channel 102 from the open end 101, the first tube body 310 and the second tube body 320 of the air duct 30 are inserted into the dust suction channel 102 in sequence, and during the insertion of the air duct 30, the second limiting portion 330 of the air duct 30 abuts against the first limiting portion 210 and pushes the first limiting portion 210 to slide in the limiting hole 103, so as to drive the brush member 20 to slide toward the inside of the device body 10, and the first buckle structure 220 slides relative to the second buckle structure 121, and the abutting block 230 of the brush member 20 extends from the opening 105 into the accommodating groove 104 to abut against the elastic member 40, and causes the elastic member 40 to undergo elastic deformation until the brush member 20 is covered by the outer shell 110 to be hidden inside the device body 10, and the brush member 20 switches from the first state to the second state, at which time the first tube body 310 is accommodated in the dust suction channel 102, and at least part of the second tube body 320 is used to be exposed outside the device body 10.

[0051] like Figure 6 As shown, when the brush member 20 is in the second state, the air duct 30 is inserted into the dust suction channel 102, the cover body 50 seals the gap 106 between the outer shell 110 and the inner shell 120, and blocks the brush member 20, the brush member 20 cannot be seen from the outside of the handheld vacuum cleaner 1, the second limiting portion 330 abuts against the first limiting portion 210, the abutting block 230 abuts against the elastic member 40, and the elastic member 40 undergoes elastic deformation.

[0052] like Figure 4 , Figure 6 and Figure 7 As shown, when the air duct 30 is separated from the dust suction channel 102, the second tube body 320 and the first tube body 310 are separated from the dust suction channel 102 in turn, and the elastic member 40 in the accommodating groove 104 is elastically reset to push the abutment block 230 to slide toward the outside of the opening end 101, so as to drive the brush member 20 to slide relative to the inner shell 120, and the first snap structure 220 slides relative to the second snap structure 121, and the first limiting portion 210 slides in the limiting hole 103 until the first limiting portion 210 abuts against the edge of the limiting hole 103, and the brush member 20 is at least partially exposed from the side of the opening end 101 relative to the device body 10, and the brush member 20 switches from the second state to the first state.

[0053] By setting an equipment body 10 and a brush member 20, wherein the equipment body 10 forms a dust suction channel 102 with an open end 101, the brush member 20 is slidably supported on the equipment body 10 and is arranged on an outer ring on the dust suction channel 102, and the brush member 20 can switch between a first state and a second state. In the first state, the brush member 20 is at least partially exposed from the side of the open end 101 relative to the equipment body 10 to assist the handheld vacuum cleaner 1 in cleaning the external environment, and in the second state, the brush member 20 is hidden inside the equipment body 10. By switching the brush member 20 between the first state and the second state, the brush member 20 is used as an integral part of the handheld vacuum cleaner 1, thereby effectively improving the integration of the handheld vacuum cleaner 1. The brush member 20 can be used and stored without additionally installing or removing the brush member 20 from the handheld vacuum cleaner 1. When the brush member 20 is needed, it is switched to the first state so that the brush member 20 is at least partially exposed from one side of the opening end 101. When the brush member 20 is not needed, it is switched to the second state so that the brush member 20 is hidden inside the device body 10, thereby effectively improving the ease of use of the handheld vacuum cleaner 1 and effectively improving the applicability of the handheld vacuum cleaner 1.
