Description

Technical Field

[0001] This application relates to the field of vacuum cleaner technology, and in particular to a floor brush for a vacuum cleaner and a vacuum cleaner. Background Technology

[0002] Currently, most stick vacuum cleaners on the market consist of a handle, main unit, dustbin, and floor brush. The dustbin component often features a handle or latch, which increases the height of the main unit, making it difficult to clean the undersides of low-legged furniture, such as sofas. For example, Chinese invention patent CN101658404A discloses a vacuum cleaner with a top cover assembly opening device. The top cover assembly has a handle with a button; pressing the button disengages the hook at the end of the lever from the hanging slot, allowing the top cover assembly to be opened and the dustbin removed. Furthermore, the dustbin component has a latch, which is aesthetically unappealing as it doesn't match the main unit's surface. The latch also occupies space, reducing the filter area inside the dustbin and making it more prone to clogging. This increases the load on the suction motor, affecting the overall performance and lifespan of the machine. Utility Model Content

[0003] The purpose of this application is to provide a floor brush for a vacuum cleaner and a vacuum cleaner.

[0004] The embodiments of this application adopt the following technical solution: a floor brush for a vacuum cleaner, comprising:

[0005] A main unit, comprising a base and a top cover, the top cover being disposed on the base;

[0006] Dust box, which is secured to the upper cover;

[0007] A pop-up mechanism is disposed between the main unit and the dustbin. The mechanism includes a connecting rod and pedals and a push block respectively disposed at both ends of the connecting rod. The push block is located below the rear edge of the dustbin, and the top surface of the pedal is lower than the top surface of the dustbin. When the pedal is depressed, it drives the connecting rod to rotate, which in turn drives the push block to flip upwards. The push block then pushes the dustbin upwards, detaching it from the top cover. Simply pressing the pedal automatically pops the dustbin up. The pop-up mechanism does not increase space occupancy in the direction of the floor brush height, thus not increasing the height of the main unit or affecting the area of ​​the filter inside the dustbin. This avoids clogging the filter and affecting the lifespan of the suction motor, and also makes it more convenient for the operator, improving the user experience.

[0008] In some embodiments, the pedal is located at the rear of the dust box, and the rear end of the upper surface of the top cover is provided with a downwardly recessed mounting groove, in which the pedal is disposed. The downwardly recessed mounting groove allows the pedal to be installed without occupying space in the height direction of the main unit, making it more suitable for low-legged furniture such as sofas.

[0009] In some embodiments, both ends of the connecting rod extend to the left and right sides of the mounting groove, respectively, between the upper cover and the base. One end of the pedal extends towards the rear of the upper cover along a first direction perpendicular to the connecting rod, and one end of the push block extends along a second direction perpendicular to the connecting rod. The first direction and the second direction are opposite, and one end of the push block abuts against the dust box. When one end of the pedal is depressed, the push block rotates around the rotation center of the connecting rod, and one end of the push block lifts upward and pushes the rear edge of the dust box away from the upper cover. The pedal and push block of the pop-up mechanism extend in two opposite directions, which makes it easier for the push block to rotate synchronously when the pedal is depressed, thereby pushing the dust box upward and detaching it from the upper cover.

[0010] In some embodiments, the pop-up mechanism further includes a bearing, an end cap, and a connecting rod cap. The bearing is disposed on the end cap, and the end cap and the connecting rod cap are respectively fixed between the upper cover and the base. One end of the connecting rod passes through the pedal and the bearing; the connecting rod cap is supported on the end of the connecting rod near the push block. The bearing, end cap, connecting rod cap, and push block are all disposed between the upper cover and the base, which does not increase the space occupied by the main unit in the height direction of the main unit and makes the floor brush more aesthetically pleasing.

[0011] In some embodiments, one end of the pusher is provided with an elastic block, one end of the elastic block is disposed on the pusher, and the other end of the elastic block abuts against the dust box. The elastic block prevents the dust box from being deformed due to a rigid push, thus effectively protecting the dust box. In addition, the elastic block can protect the pusher and prevent it from deforming or breaking.

[0012] In some embodiments, the floor brush of the vacuum cleaner further includes an elastic support mechanism located below the pop-up mechanism and disposed on the base. When the dustbin detaches from the top cover under the pushing action of the pop-up mechanism, the elastic support mechanism applies an upward supporting force to the dustbin to support it. The elastic support mechanism further ensures support for the dustbin, facilitating its removal from the top cover. The elastic support mechanism and the pop-up mechanism work together to make it easier to pop the dustbin up to a certain extent.

[0013] In some embodiments, the elastic support mechanism includes a rocker plate and a compression spring;

[0014] One end of the rocker is rotatably connected to the base, and the other end of the rocker abuts against the bottom surface of the dust box;

[0015] One end of the compression spring is disposed on the base, and the other end of the compression spring is disposed on the rocker plate;

[0016] When the dust box detaches from the top cover under the pushing action of the pop-up mechanism, the compression spring extends, pushing the other end of the rocker plate upward to flip and support the dust box.

[0017] The elastic support mechanism is relatively simple and easy to achieve elastic support for the dust box.

[0018] In some embodiments, the upper cover and the base enclose a mounting position. The top of the upper cover has an opening for the dust box to be inserted into the mounting position. A rear roller is provided on the rear side of the upper cover corresponding to the opening, and a front sliding buckle is provided on the front side of the upper cover corresponding to the opening. The dust box has a rear groove and a front groove respectively corresponding to the positions of the rear roller and the front sliding buckle. When the dust box is installed in the mounting position, the rear roller is secured in the rear groove, and the front sliding buckle is secured in the front groove. This securing method allows for the detachable installation of the dust box without increasing the height of the main unit in the height direction.

[0019] In some embodiments, the upper cover is provided with a rear spring and a front spring. One end of the rear spring is disposed on the upper cover, and the other end of the rear spring is disposed on the rear roller. One end of the front spring is disposed on the upper cover, and the other end of the front spring is disposed on the front sliding buckle. When the dust box is secured to the upper cover, the rear spring extends, pushing the rear roller to secure itself in the rear groove, and the front spring extends, pushing the front sliding buckle to secure itself in the front groove. This structure facilitates the secure installation and quick disassembly of the dust box, allowing the dust box to quickly detach from the upper cover when pushed upward by the protrusion.

[0020] This application also provides a vacuum cleaner, including a push rod and a floor brush as described in any of the above embodiments, wherein the upper cover of the floor brush is provided with a connecting structure for connecting the push rod. This vacuum cleaner can be applied to scenarios such as low-leg sofas, thus expanding its applicability. Attached Figure Description

[0035] It should be understood that various modifications can be made to the embodiments described herein. Therefore, the above description should not be considered as limiting, but merely as an example of embodiments. Other modifications within the scope and spirit of this application will be apparent to those skilled in the art.

[0036] The accompanying drawings, which are included in and form part of this specification, illustrate embodiments of the present application and, together with the general description of the present application given above and the detailed description of the embodiments given below, serve to explain the principles of the present application.

[0037] These and other features of this application will become apparent from the following description of preferred forms of embodiments given as non-limiting examples, with reference to the accompanying drawings.

[0038] It should also be understood that although this application has been described with reference to some specific examples, those skilled in the art can certainly implement many other equivalent forms of this application.

[0039] The above and other aspects, features and advantages of this application will become more apparent when taken in conjunction with the accompanying drawings and in view of the following detailed description.

[0040] Specific embodiments of this application are described thereafter with reference to the accompanying drawings; however, it should be understood that the claimed embodiments are merely examples of this application, which can be implemented in various ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that could obscure the application. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use this application in a variety of substantially any suitable detailed structures.

[0041] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.

[0042] To address the problems in the background technology, this application provides a floor brush for a vacuum cleaner, such as... Figure 1 As shown, the floor brush of this vacuum cleaner may include a main unit 2, a dustbin 3, and a pop-up mechanism for lifting the dustbin 3. Of course, as... Figure 3 and Figure 4 As shown, the floor brush may also include components such as a roller brush 20 and a suction motor 5 mounted on the main unit 2. The suction motor 5 rotates at high speed, drawing air away from the dust box 3 and the cavity of the high-speed rotating roller brush 20, thus generating a certain negative pressure. The high-speed rotating roller brush 20 beats and draws dust or particulate matter 21 into the dust box 3. The drawn-in air passes through the coarse 19 and fine filter devices in the dust box 3, and then is discharged through the air outlet of the fan blades in the suction motor 5.

[0043] The main unit 2 includes a base 4 and an upper cover 6, with the upper cover 6 mounted on the base 4. Figure 2 As shown, the upper cover 6 can be enclosed with the base 4 to form a mounting position for the dust box 3. This mounting position can be a space that corresponds to and fits the shape of the dust box 3. A sealing ring 22 can be provided between the outer edge of the dust box 3 and the mounting position to prevent dust and other substances from leaking out. In addition, the upper cover 6 and the base 4 can also form a space for the suction motor 5 to be installed. The suction motor 5 can be connected to the outlet of the coarse 19 and fine filter device inside the dust box 3, so that dust and other particulate matter 21 (including other garbage) on the ground can be adsorbed into the coarse 19 and fine filter device in the dust box 3 by the high-speed rotation of the roller brush 20 through the air circulation. The front end of the upper cover 6 can be provided with a cavity for installing the roller brush 20, and the roller brush 20 can be placed in the cavity.

[0044] The dustbin 3 can be secured to the upper cover 6, for example, it can be secured to the mounting position formed by the upper cover 6 and the base 4. At the mounting position, the dustbin 3 is pressed down, securing it in place. Most of the dustbin 3 extends into the mounting position, with the top surface of the dustbin 3 exposed. Figure 10 As shown, the dust box 3 can have a collection chamber, and the collection chamber of the dust box 3 can be connected to the cavity where the roller brush 20 is installed. Dust and other particulate matter 21 enter the cavity under the high-speed rolling action of the roller brush 20 and the suction action of the suction motor 5, and then enter the collection chamber of the dust box 3, as shown. Figure 9 As shown, the coarse filter 19 and the fine filter device can be installed inside the collection chamber of the dust box 3. The coarse filter 19 and the fine filter device can filter dust and other particulate matter 21 that are sucked into the collection chamber.

[0045] like Figure 3 , Figure 5 , Figure 6 as well as Figure 7 As shown, a pop-up mechanism is located between the main unit 2 and the dustbin 3. Specifically, the pop-up mechanism can be located on the upper cover 6. The pop-up mechanism includes a connecting rod 12 and a pedal 13 and a push block 11 respectively located at both ends of the connecting rod 12. The push block 11 is located below the rear edge of the dustbin 3, and the top surface of the pedal 13 is lower than the top surface of the dustbin 3 to avoid increasing the height of the main unit 2 due to the pop-up mechanism. The pedal 13 is exposed on the surface of the main unit 2, and the top surface of the pedal 13 forms a stepping surface. The front end of the pedal 13 can be connected to the connecting rod 12, and the pedal 13 and the connecting rod 12 are relatively fixed. The rear end of the push block 11 can be connected to the connecting rod 12, and the push block 11 and the connecting rod 12 are relatively fixed. When in use, you can step on the pedal 13 backward and downward with your foot, so that the rear end of the pedal 13 can rotate relative to the front end of the pedal 13 around the axis (rotation center) of the connecting rod 12. At the same time, the connecting rod 12 rotates synchronously with the rotation of the pedal 13. The rotation of the connecting rod 12 drives the push block 11 to rotate synchronously around the axis of the connecting rod 12. The front end of the push block 11 flips upward. At this time, the push block 11 will push the rear edge of the dust box 3 from below, so that the dust box 3 can overcome the locking force of the main unit 2 on the dust box 3 and pry up the rear edge of the dust box 3, so that the dust box 3 can be released from the locking force of the main unit 2 on the dust box 3.

[0046] In this embodiment, when the dustbin 3 is lifted, the foot pedal 13 can be directly stepped on, and the dustbin 3 will automatically pop up. The pop-up mechanism does not increase the space occupied in the height direction of the floor brush, so it does not increase the height of the main unit 2, nor does it occupy the area of ​​the filter inside the dustbin 3. This avoids clogging the filter inside the dustbin 3 and affecting the life of the suction motor 5, and also makes it more convenient for the operator to use, improving the user experience.

[0047] In some embodiments, combined with Figure 2The pedal 13 can be located at the rear of the dustbin 3. A recessed mounting groove is provided at the rear end of the upper surface of the cover 6, and the pedal 13 can be placed within this groove. Alternatively, the pedal 13 can be placed in other positions. For example, depending on the shape of the connecting rod 12, a mounting groove can be provided on the left or right side of the upper surface of the cover 6 (the side away from the push block 11), and the pedal 13 can be placed in the corresponding mounting groove position, as long as it can drive the connecting rod 12 to rotate when the pedal 13 is pressed down, thereby driving the push block 11 to rotate. This is merely an example and does not constitute a limitation on the scope of the claims. Placing the pedal 13 at the rear of the dustbin 3 allows for more efficient use of the space of the vacuum cleaner's floor brush. The size of the mounting groove can be slightly larger than the size of the pedal 13 to prevent the pedal 13 from scratching the mounting groove during vertical movement. The recessed mounting groove allows the pedal 13 to be installed within it without occupying the vertical space of the main unit 2, making it more suitable for low-legged furniture such as sofas. In addition, the mounting slot is located at the rear end of the upper surface of the cover 6, making it convenient for the user to lift their foot to step on the pedal 13 during use.

[0048] In some embodiments, combined with Figure 2 and Figure 5 Both ends of the connecting rod 12 extend to the left and right sides of the mounting groove into the space between the upper cover 6 and the base 4. That is, for the pop-up mechanism, apart from the pedal 13 and the part of the connecting rod 12 connected to the pedal 13 that are exposed, the other parts of the connecting rod 12 and the push block 11 connected to the connecting rod 12 are all set in the space between the upper cover 6 and the base 4, making the floor brush look more beautiful.

[0049] One end (rear end) of the pedal 13 extends towards the rear of the upper cover 6 in a first direction perpendicular to the connecting rod 12 (towards the rear of the upper cover 6), and one end (front end) of the push block 11 extends towards the front of the upper cover 6 in a second direction perpendicular to the connecting rod 12. The first direction is opposite to the second direction, and one end (front end) of the push block 11 can abut against the dust box 3. The above-described design of the push block 11 and the pedal 13 forms a seesaw-like structure, which makes it easier to rotate the front end of the push block 11 relative to its rear end when the pedal 13 is pressed, thereby making it easier to push the dust box 3 upward and release it from the upper cover 6. A platform can be provided below the outer edge where the dust box 3 is secured to the top cover 6. The front end of the push block 11 can abut against the platform on the dust box 3. The platform and the upper surface of the push block 11 can form surface contact. When the front end of the push block 11 flips, the dust box 3 can be pushed upward to move away from the securing effect of the top cover 6 by applying an upward force to the platform of the dust box 3.

[0050] Of course, it is understandable that, in addition to extending forward in the second direction, the push block 11 can also tilt downward so that the push block 11 can form a good contact relationship with the dust box 3.

[0051] When one end (rear end) of the pedal 13 is depressed, one end (front end) of the push block 11 can be lifted upwards and push the rear edge of the dust box 3 out of the locking mechanism of the upper cover 6. At this time, the front side of the dust box 3 will also be released from the locking mechanism of the upper cover 6. The dust box 3 can then be removed from the upper cover 6 to clean the dust box 3 and the particulate matter 21 inside the coarse 19 and fine filter devices. After cleaning, the dust box 3 can be placed in the corresponding installation position on the upper cover 6, and the dust box 3 can be pressed down to lock it back into place on the upper cover 6. During the installation of the dust box 3, the push block 11 can be pressed down to reset the push block 11.

[0052] Of course, since the front end of the push block 11 extends a certain distance to the front side of the upper cover 6, the push block 11 can also be reset due to its own gravity.

[0053] Alternatively, a reset spring can be installed below the pedal 13. When the pedal 13 is pressed down, the reset spring is compressed. When the pedal 13 is released, the reset spring can reset the pedal 13, thereby resetting the push block 11.

[0054] It is understandable that other structural designs can also be used to achieve the reset of pedal 13 and push block 11. This is only used as an example and does not constitute a limitation on the scope of protection of the claims.

[0055] The pedal 13 and push block 11 of the pop-up mechanism extend in two opposite directions, so that when the pedal 13 is pressed down, the push block 11 can more easily achieve synchronous flipping, so as to push the dust box 3 upward and detach it from the top cover 6.

[0056] In some embodiments, such as Figure 3 , Figure 5 and Figure 11As shown, the pop-up mechanism also includes a bearing 15, an end cap 16, and a connecting rod cap 14. The bearing 15 is mounted on the end cap 16, and the end cap 16 and connecting rod cap 14 are respectively fixed between the upper cover 6 and the base 4. For example, the bearing 15 and connecting rod cap 14 can be fixed to the inner surface of the upper cover 6 by screws. One end of the connecting rod 12 can pass through the pedal 13 and the bearing 15, and the connecting rod cap 14 supports the end of the connecting rod 12 near the push block 11. An arc-shaped groove can be formed in the middle of the connecting rod cap 14, which can cover the connecting rod 12. The arc-shaped groove on the connecting rod cap 14 can be located below the connecting rod 12. Screw holes can be provided at both ends of the connecting rod cap 14 for fixing it to the upper cover 6, and the two ends of the connecting rod cap 14 are fixed to the upper cover 6 by screws. The bearing 15, end cap 16, and connecting rod cap 14 provide stable support for the connecting rod 12.

[0057] Combination Figure 5 The bearing 15, end cap 16, connecting rod cap 14, and push block 11 are all located between the upper cover 6 and the base 4, which does not increase the space occupied by the main unit 2 in the height direction and makes the floor brush more aesthetically pleasing.

[0058] In some embodiments, an elastic block 28 may be provided at one end of the push block 11. One end of the elastic block 28 is located at the front end of the push block 11, and the other end of the elastic block 28 abuts against the dust box 3. The push block 11 may be made of hard plastic or metal, while the elastic block 28 may be made of rubber or other materials. A mounting hole may be provided at the front end of the push block 11. One end of the elastic block 28 extends into the mounting hole and is fixed in the mounting hole, while the other end of the elastic block 28 extends upward. Continuing with the above embodiments, the elastic block 28 can abut against the platform position of the dust box 3.

[0059] The elastic block 28 prevents the dust box 3 from being deformed or damaged due to a hard push, thus effectively protecting the dust box 3. In addition, the elastic block 28 protects the pusher block 11, preventing it from deforming or breaking.

[0060] In some embodiments, such as Figure 3 , Figure 6 , Figure 8 and Figure 9 As shown, the floor brush of the vacuum cleaner also includes a flexible support mechanism, which can be located below the pop-up mechanism. Depending on the needs, one or two flexible support mechanisms can be provided, with two flexible support mechanisms supporting the dustbin 3 from the left and right sides respectively. The flexible support mechanism can be mounted on the base 4, located in the space between the upper cover 6 and the base 4, without increasing the vertical occupancy of the main unit 2.

[0061] When the dustbin 3 is secured to the upper cover 6, there is an elastic force between the dustbin 3 and the elastic support mechanism, compressing the elastic support mechanism. When the dustbin 3 is pushed off the upper cover 6 by the pop-up mechanism, the compression of the elastic support mechanism is released, and the elastic support mechanism applies an upward supporting force to the dustbin 3, thus maintaining the dustbin 3 free from the secured state of the upper cover 6. Furthermore, when the pusher block 11 of the pop-up mechanism applies an upward pushing force to the dustbin 3, the elastic support mechanism also applies an upward elastic force to the dustbin 3. The elastic support mechanism and the pop-up mechanism work together to make it easier to pop the dustbin 3 off.

[0062] It should be noted that even with the upward force exerted by the elastic support mechanism on the dust box 3, the dust box 3 cannot be disengaged from the locking action of the upper cover 6.

[0063] The flexible support mechanism can further ensure the support of the dust box 3, making it easy for the dust box 3 to be removed from the top cover 6.

[0064] In some embodiments, the elastic support mechanism includes a rocker 10 and a compression spring 9.

[0065] One end of the rocker arm 10 is rotatably connected to the base 4, and the other end of the rocker arm 10 abuts against the bottom surface of the dust box 3. One end of the compression spring 9 is disposed on the base 4, and the other end of the compression spring 9 is disposed on the rocker arm 10. For example, the other end of the compression spring 9 abuts against or is fixed to the bottom surface of the rocker arm 10. A receiving cavity for accommodating the upper part of the compression spring 9 can be provided on the bottom surface of the rocker arm 10. This receiving cavity can also play a guiding role when the compression spring 9 is compressed and extended, so as to prevent the compression spring 9 from shaking and affecting the stability of the rocker arm 10.

[0066] As mentioned earlier, when the dust box 3 is installed on the upper cover 6, the dust box 3 will press down on the other end of the rocker arm, and the compression spring 9 will be in a compressed state. When the pedal 13 is pressed down and pushes the push block 11 to push the dust box 3 upward, the compression spring 9 can extend and push the other end of the rocker arm 10 to flip upward, so as to apply an upward force to the dust box 3, and push and support the dust box 3 upward.

[0067] Additionally, a connecting seat 7 can be installed on the base 4, and the connecting seat 7 can be fixed to the base 4. The connecting seat 7 can be hinged to one end of the rocker 10 via a hinge shaft 8, and the other end of the rocker 10 can rotate around the hinge shaft 8. A compression spring 9 can be installed between the connecting seat 7 and the rocker 10. A guide shaft can also be installed on the connecting seat 7, and the guide shaft is arranged parallel to the hinge shaft 8. The rocker 10 is provided with an arc-shaped guide hole, and both ends of the guide shaft can extend into the guide hole. When the rocker 10 rotates around the hinge shaft 8, the guide hole can move relative to the guide shaft. The cooperation between the guide hole and the guide shaft can guide and limit the rotation of the rocker 10, further ensuring the smoothness of the rotation of the rocker 10.

[0068] The elastic support mechanism is relatively simple and easy to achieve elastic support for the dust box 3.

[0069] In some embodiments, as described in the above embodiments, the upper cover 6 and the base 4 enclose a mounting position, and the top of the upper cover 6 has an opening for the dust box 3 to be installed in the mounting position. A rear roller 17 is provided on the rear side of the upper cover 6 corresponding to the opening, and a front sliding buckle 18 is provided on the front side of the upper cover 6 corresponding to the opening. The dust box 3 has a rear groove and a front groove respectively corresponding to the positions of the rear roller 17 and the front sliding buckle 18. When the dust box 3 is installed in the mounting position, the rear roller 17 is locked in the rear groove, and the front sliding buckle 18 is locked in the front groove. That is, both the front sliding buckle 18 and the rear roller 17 protrude towards the inner side of the mounting position. When the dust box 3 is installed, the dust box 3 is pressed down, causing the rear groove and the front groove of the dust box 3 to move downward until the front sliding buckle 18 is locked in the front groove and the rear roller 17 is locked in the rear groove, thereby securing the dust box 3.

[0070] During the installation of dust box 3, the rear roller 17 can roll under the downward pressure of dust box 3, avoiding any impact or damage to dust box 3 during the installation process.

[0071] The end of the front sliding buckle 18 facing the inside of the mounting position can be set as a hemispherical shape with a smooth surface, which also avoids the front sliding buckle 18 from damaging the dust box 3 during the installation process.

[0072] The above-mentioned fastening method provided in this application enables the dust box 3 to be detachably installed, and does not increase the height of the main unit 2 in the height direction.

[0073] In some embodiments, such as Figure 3 , Figure 6 , Figure 8 and Figure 9 As shown, the upper cover 6 is also provided with a rear spring 25 and a front spring 27. One end of the rear spring 25 is provided on the upper cover 6 and the other end of the rear spring 25 is provided on the rear roller 17. The other end of the rear spring 25 can be provided with a transition connector 24. A roller 23 can be provided on the transition connector 24. The rear roller 17 can be connected to the roller 23 and can rotate relative to the roller 23.

[0074] Specifically, a roller box 26 for mounting the rear spring 25 can be provided on the upper cover 6. The roller box has a hole for accommodating the rear spring 25, which can be disposed in the hole and can extend and compress along the hole.

[0075] One end of the front spring 27 can be mounted on the upper cover 6, and the other end of the front spring 27 can be mounted on the front slide buckle 18. Similarly, a housing for mounting the front slide buckle 18 can be provided on the upper cover 6. The housing also has a hole in which the front slide buckle 18 can be mounted and can extend and compress along the hole.

[0076] When the dust box 3 is secured to the upper cover 6, the rear spring 25 extends, pushing the rear roller 17 to secure itself in the rear groove, and the front spring 27 extends, pushing the front sliding buckle 18 to secure itself in the front groove.

[0077] Specifically, when the dustbin 3 is not installed on the top cover 6, both the front spring 27 and the rear spring 25 are in an extended state. During the installation of the dustbin 3, as the dustbin 3 moves downward, it also compresses the rear roller 17 and the front sliding buckle 18, causing the rear spring 25 and the front spring 27 to compress into the corresponding holes. As the dustbin 3 descends, when the front groove and the rear groove move to the height positions corresponding to the front sliding buckle 18 and the rear roller 17 respectively, the front spring 27 and the rear spring 25 extend again and push the front sliding buckle 18 and the rear roller 17 to lock into the front groove and the rear groove respectively. When the dustbin 3 is lifted by the pop-up mechanism, the movement of the rear roller 17 and the front sliding buckle 18 is reversed.

[0078] The structure of the elastic support mechanism described above in this application facilitates the secure installation and quick disassembly of the dust box 3, enabling the dust box 3 to quickly detach from the top cover 6 when pushed upward by the protrusion.

[0079] This application also provides a vacuum cleaner, including a push rod and a floor brush as described in any of the above embodiments. The upper cover 6 of the floor brush is provided with a connecting structure for connecting the push rod. This connecting structure can be as follows: Figure 1 The push rod connection structure 1 shown is applicable to low-leg sofas and other similar applications, thus expanding its versatility.

[0080] The foregoing has described in detail several embodiments of this application, but this application is not limited to these specific embodiments. Those skilled in the art can make various variations and modifications based on the concept of this application, and all such variations and modifications should fall within the scope of protection claimed in this application.
