Abstract
Description
Technical Field
[0001] This disclosure relates to the field of electrical technology, and in particular to a vacuum cleaner. Background Technology
[0002] Portable vacuum cleaners, as small vacuum cleaners that can be used in both homes and cars, meet people's needs for cleaning in confined spaces such as car interiors, desktops, and keyboards—areas where cleaning is inconvenient. These vacuum cleaners work by using an electric motor to generate negative pressure, sucking in dust and debris from the air. They are equipped with different types of nozzles, brushes, and air nozzles to adapt to the cleaning needs of surfaces with various shapes. For easy cleaning of the dust cup after long-term use, the dust cup is designed to be detachably connected to the main body, allowing users to perform routine maintenance and cleaning more conveniently.
[0003] In related technologies, the dust cup has a slot at the junction with the main body, and a corresponding buckle is provided on the main body. When the dust cup rotates relative to the main body, the slot can engage with the buckle. However, during the installation of the dust cup, the locking function is achieved through plastic deformation caused by compressive force between the slot of the dust cup and the buckle of the main body. This makes installing and removing the dust cup relatively laborious, and the installation process can easily lead to wear on the mating structure. Utility Model Content
[0004] In view of this, the present disclosure provides a vacuum cleaner that allows for easier installation or removal of the body and dust cup.
[0005] Specifically, the following technical solutions are included:
[0006] In a first aspect, embodiments of this disclosure provide a vacuum cleaner, including:
[0007] A dust cup includes a cup body, a bracket, and a button. The bracket is connected to the side of the cup body, and the button is retractably mounted on the bracket.
[0008] The main body is detachably connected to one end of the dust cup via a rotatable mechanism;
[0009] The body includes a limiting member and a handle. The limiting member is retractably connected to the end of the handle near the dust cup. The button is configured to control the limiting member to extend or retract relative to the handle. The bracket is provided with a first limiting groove at the end near the handle. When the limiting member extends, it is inserted into the first limiting groove.
[0010] In some embodiments of this disclosure, the button is configured to extend and retract along a first direction, and the limiting member is configured to extend and retract along a second direction, the first direction being perpendicular to the second direction. The end of the button near the cup body has a first surface inclined relative to the first direction, and the end of the limiting member near the support has a second surface inclined relative to the second direction. The first surface and the second surface abut against each other. When the button is pressed down, the button pushes the limiting member away from the support via the first and second surfaces, thereby moving the limiting member outside the first limiting groove.
[0011] In some embodiments of this disclosure, the limiting member is cylindrical, the sidewall of the first limiting groove has an opening structure, the button portion is located within the opening structure, the first surface constitutes part of the sidewall of the first limiting groove, and the second surface is a chamfered surface of the end of the limiting member near the bracket. The sidewall of the first limiting groove abuts against the second surface. The structure of the second surface being a chamfered surface of the limiting member allows the limiting member to be pushed in multiple directions. The edge of the bracket can push the limiting member to retract, allowing the limiting member to pass over the end face of the bracket and enter the first limiting groove.
[0012] In some embodiments of this disclosure, the limiting member has a second limiting groove on its end face near the bracket, and the bottom of the first limiting groove has a protrusion that engages with the second limiting groove. This engagement of the protrusion and the second limiting groove further restricts the relative position of the limiting member and the bracket, preventing the bracket from rotating relative to the handle when the button is not pressed.
[0013] In some embodiments of this disclosure, a guide groove is provided on the side of the button near the cup body, and the bottom portion of the first limiting groove is located within the guide groove and slides in cooperation with the guide groove. The structure of the guide groove cooperating with the bottom of the first limiting groove is used to restrict the movement direction of the button, so that the button can only move telescopically in a first direction.
[0014] In some embodiments of this disclosure, the dust cup further includes a first elastic member, the two ends of which are fixedly connected to the button and the bracket, respectively. The first elastic member is used to allow the button to reset after being pressed.
[0015] In some embodiments of this disclosure, the body further includes a second elastic member, the two ends of which are fixedly connected to the limiting member and the handle, respectively. The second elastic member is used to provide a thrust to the limiting member in the direction of support.
[0016] In some embodiments of this disclosure, the handle has a mounting groove at one end near the bracket, the inner wall of the mounting groove has a first locking groove, and the limiting member has a first buckle at the end away from the bracket. The first buckle engages with the first locking groove. The structure of the first buckle and the first locking groove is used to install the limiting member into the handle, provide space for the limiting member to extend and retract along a second direction, and prevent the limiting member from falling off the handle.
[0017] In some embodiments of this disclosure, the machine body further includes an outer cylinder, the outer wall of which is connected to the handle. A second buckle is provided on the inner wall of the outer cylinder near the end of the cup body, and a second slot is provided on the end of the cup body near the outer cylinder. The second slot is L-shaped and communicates with the end face of the cup body. The second buckle engages with the second slot. This engagement allows for a detachable, rotatable connection between the machine body and the dust cup.
[0018] In some embodiments of this disclosure, a third latch is provided at the end of the button near the cup body, and a third slot is provided on the bracket, with the third latch engaging with the third slot. The structure of the third latch and the third slot is used to install the button into the bracket, provide space for the button to retract and move along a first direction a, and prevent the button from falling off the bracket.
[0019] In some embodiments of this disclosure, the dust cup further includes an air duct located within the support and communicating with the interior of the cup body. The air duct provides a channel for external dust to enter the cup body.
[0020] The beneficial effects of the technical solutions provided in this disclosure include at least the following:
[0021] In the vacuum cleaner provided in this embodiment, the body and dust cup are detachably connected by rotation. When the limiting member of the body is engaged with the first limiting groove on the dust cup, the body cannot rotate relative to the dust cup, thus fixing the body and dust cup in place. When the button is pressed to separate the limiting member from the first limiting groove, the body can rotate relative to the dust cup, thereby separating the body from the dust cup. This embodiment controls the connection and separation of the body and dust cup via a button, eliminating the need for plastically deformable clips to connect the body and dust cup. This facilitates the installation and removal of the dust cup, prevents damage to the connection structure between the body and dust cup, and helps to extend the service life of the vacuum cleaner.

Detailed Implementation
[0035] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.
[0036] Figure 1 A schematic diagram of a vacuum cleaner provided in an embodiment of this disclosure; Figure 2 This is a schematic diagram of the body of a vacuum cleaner provided in an embodiment of this disclosure; Figure 3 This is a schematic diagram of the bracket for a vacuum cleaner provided in an embodiment of this disclosure.
[0037] like Figure 1-3 As shown, the vacuum cleaner provided in this embodiment includes:
[0038] The dust cup 1 includes a cup body 101, a bracket 102 and a button 103. The bracket 102 is connected to the side of the cup body 101, and the button 103 is retractably mounted on the bracket 102.
[0039] The main body 2 is detachably connected to one end of the dust cup 1 by rotation;
[0040] The body 2 includes a limiting member 201 and a handle 202. The limiting member 201 and the handle 202 are retractably connected to one end near the dust cup 1. The button 103 is configured to control the extension or retraction of the limiting member 201 relative to the handle 202. The bracket 102 is provided with a first limiting groove 1021 at one end near the handle 202. When the limiting member 201 is extended, it is inserted into the first limiting groove 1021.
[0041] In the vacuum cleaner provided in this embodiment, the body 2 and the dust cup 1 are detachably connected by rotation. When the limiting member 201 of the body 2 is engaged with the first limiting groove 1021 provided on the dust cup 1, the body 2 cannot rotate relative to the dust cup 1, thereby locking the body 2 and the dust cup 1. When the button 103 is pressed to separate the limiting member 201 from the first limiting groove 1021, the body 2 can rotate relative to the dust cup 1, thereby separating the body 2 from the dust cup 1. In this embodiment, the connection and separation of the body 2 and the dust cup 1 are controlled by the button 103, eliminating the need for a plastically deformable snap-fit connection between the body 2 and the dust cup 1. This facilitates the installation and removal of the dust cup 1, prevents damage to the connection structure between the body 2 and the dust cup 1, and helps to improve the service life of the vacuum cleaner.
[0042] To make the technical solutions and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.
[0043] like Figure 1 As shown, the vacuum cleaner provided in this embodiment includes a dust cup 1 and a body 2, with the body 2 detachably connected to one end of the dust cup 1 via a rotatable mechanism. The dust cup 1 includes a cup body 101, a bracket 102, and a button 103. The bracket 102 is connected to the side of the cup body 101, and the button 103 is retractably mounted on the bracket 102. Figure 2 As shown, the body 2 includes a limiting member 201 and a handle 202. The handle 202 is disposed opposite to the bracket 102. The limiting member 201 and the end of the handle 202 near the bracket 102 are retractably connected. When the button 103 is pressed, the limiting member 201 can be controlled to retract; when the button 103 is released, the limiting member 201 can be controlled to extend. Figure 3 As shown, a first limiting groove 1021 is provided at one end of the bracket 102 near the handle 202. When the limiting member 201 extends, it engages with the first limiting groove 1021 to prevent the dust cup 1 from rotating relative to the body 2, thereby fixing the dust cup 1 and the body 2 in place. When the button 103 is pressed, causing the limiting member 201 to retract beyond the first limiting groove 1021, the dust cup 1 can rotate relative to the body 2, thus allowing the dust cup 1 to be separated from the body 2 by rotation.
[0044] Figure 4 This is a partial cross-sectional schematic diagram of a vacuum cleaner provided in an embodiment of this disclosure. In some embodiments of this disclosure, such as... Figure 4 As shown, button 103 is configured to extend and retract along a first direction a, and limiting member 201 is configured to extend and retract along a second direction b. The first direction a is perpendicular to the second direction b. One end of button 103 near the cup body 101 has a first surface 1031 inclined relative to the first direction a, and one end of limiting member 201 near the support 102 has a second surface 2011 inclined relative to the second direction b. The first surface 1031 and the second surface 2011 abut against each other. When button 103 is pressed down, button 103 pushes limiting member 201 away from the support 102 via the first surface 1031 and the second surface 2011, thereby moving limiting member 201 outside the first limiting groove 1021.
[0045] Optionally, the angle between the first direction a and the first surface 1031 is 90°, and the angle between the second direction b and the second surface 2011 is 90°, so that the force on the button 103 and the limiting member 201 is more balanced, thereby improving the stability when the button 103 is pressed.
[0046] In some embodiments of this disclosure, such as Figure 4 As shown, the dust cup 1 also includes a first elastic element 104, the two ends of which are fixedly connected to the button 103 and the bracket 102, respectively. The first elastic element 104 is in a compressed state, so that the button 103 can be reset after being pressed.
[0047] In some embodiments of this disclosure, such as Figure 4 As shown, the body 2 also includes a second elastic member 204, the two ends of which are fixedly connected to the limiting member 201 and the handle 202, respectively. The second elastic member 204 is in a compressed state, thereby providing a thrust to the limiting member 201 in the direction toward the bracket 102.
[0048] It should be noted that the first elastic element 104 and the second elastic element 204 provided in the embodiments of this disclosure can be compression springs, respectively.
[0049] In some embodiments of this disclosure, see Figure 4 The handle 202 has a mounting groove 2021 at one end near the bracket 102, and a first locking groove 2022 is provided on the inner wall of the mounting groove 2021. The limiting member 201 has a first buckle 2013 at the end away from the bracket 102, and the first buckle 2013 engages with the first locking groove 2022. Specifically, the limiting member 201 has multiple first buckles 2013 along its circumference, and the inner wall of the mounting groove 2021 has multiple first locking grooves 2022 along its circumference. Each first buckle 2013 engages with one first locking groove 1022. The structure of the first buckles 2013 and the first locking grooves 1022 is used to install the limiting member 201 into the handle 202, provide space for the limiting member 201 to extend and retract along the second direction b, and prevent the limiting member 201 from falling off the handle 202.
[0050] Optionally, such as Figure 4 As shown, the dust cup 1 also includes an air duct 105, which is located inside the bracket 102 and communicates with the interior of the cup body 101. The air duct 105 can be fixedly connected to the bracket 102 by bolts, and the air duct 105 is used to provide a channel for external dust to enter the cup body 101.
[0051] Figure 5 A schematic diagram of a limiting member for a vacuum cleaner provided in an embodiment of this disclosure. In some embodiments of this disclosure, such as... Figure 3 and 5 As shown, the limiting member 201 is cylindrical, and the side wall of the first limiting groove 1021 is provided with an opening structure 1023. The button 103 is located in the opening structure 1023. The first surface 1031 forms part of the side wall of the first limiting groove 1021. The second surface 2011 is the chamfered surface of the end of the limiting member 201 near the bracket 102. The side wall of the first limiting groove 1021 abuts against the second surface 2011.
[0052] For example, the limiting member 201 is cylindrical, and the second surface 2011 is the chamfered surface of the limiting member 201. This structure allows the limiting member 201 to be pushed in multiple directions. During the process of installing the dust cup 1 onto the body 2, the bracket 102 rotates relative to the handle 202, and the edge of the bracket 102 can also abut against the second surface 2011. Since the second surface 2011 is inclined relative to the second direction b, the edge of the bracket 102 can push the limiting member 201 to retract, so that the limiting member 201 can pass over the end face of the bracket 102 and enter the first limiting groove 1021.
[0053] In some embodiments of this disclosure, such as Figure 3 and 5 As shown, the limiting member 201 has a second limiting groove 2012 on its end face near the bracket 102, and a protrusion 1022 is provided at the bottom of the first limiting groove 1021. The protrusion 1022 is inserted into the second limiting groove 2012. The structure of the protrusion 1022 and the second limiting groove 2012 further restricts the relative position of the limiting member 201 and the bracket 102, preventing the bracket 102 from rotating relative to the handle 202 when the button 103 is not pressed.
[0054] Figure 6 This is a schematic diagram of the dust cup of a vacuum cleaner provided in an embodiment of this disclosure. In some embodiments of this disclosure, such as... Figure 2 and 6 As shown, the body 2 also includes an outer cylinder 203. The outer wall of the outer cylinder 203 is connected to the handle 202. A second buckle 2031 is provided on the inner wall of the end of the outer cylinder 203 near the cup body 101. A second slot 1011 is provided on the end of the cup body 101 near the outer cylinder 203. The second slot 1011 is L-shaped and communicates with the end face of the cup body 101. The second buckle 2031 engages with the second slot 1011 to achieve a detachable connection between the body 2 and the dust cup 1 by rotation. When installing the body 2 and the dust cup 1, the second slot 1011 and the second buckle 2031 can be aligned first. After inserting the second buckle 2031 into the second slot 1011, the dust cup 1 can be rotated to allow the second buckle 2031 to enter the end of the second slot 1011, thus preventing the outer cylinder 203 from separating axially from the cup body 101.
[0055] It should be noted that the detachable connection between the body 2 and the dust cup 1 at one end in a rotatable manner in the embodiments of this disclosure can also be implemented in other ways, such as providing an internal thread on the inner wall of the outer cylinder 203 and an external thread on the outer wall of the cup body 101, with the outer cylinder 203 and the cup body 101 connected by threads.
[0056] Figure 7 This is a schematic diagram of a button on a vacuum cleaner provided in an embodiment of this disclosure. In some embodiments of this disclosure, such as... Figure 4 and 7As shown, a guide groove 1032 is provided on the side of the button 103 near the cup body 101. The bottom part of the first limiting groove 1021 is located in the guide groove 1032 and slides in cooperation with the guide groove 1032. The structure in which the guide groove 1032 cooperates with the bottom of the first limiting groove 1021 is used to restrict the movement direction of the button 103, so that the button 103 can only move in the first direction a.
[0057] In some embodiments of this disclosure, see Figure 4 and 7 A third latch 1033 is provided at the end of button 103 near cup body 101, and a third slot 1024 is provided on bracket 102. The third latch 1033 and the third slot 1024 engage with each other. The structure of the third latch 1033 and the third slot 1024 is used to install button 103 into bracket 102, and to provide space for button 103 to move telescopically along the first direction a, while preventing button 103 from falling off bracket 102.
