Description

Technical Field

[0001] The present invention relates to the technical field of cleaning devices, and in particular to a vacuum cleaner provided with a dust collecting bag. Background Art

[0002] To facilitate cleaning, some existing vacuum cleaners are equipped with dust bags that collect dust. When the dust bag is full, the user simply removes the dust bag from the vacuum cleaner and replaces it with a new one before continuing cleaning. This allows users to clean more quickly and saves time as they do not need to frequently clean the vacuum cleaner.

[0003] The dust bag of an existing vacuum cleaner is mainly installed on the vacuum cleaner through the following methods: 1. The dust bag is directly installed on the vacuum cleaner through a snap-on structure; 2. A dust bag plate is provided and the dust bag is installed on the dust bag plate. Correspondingly, the vacuum cleaner is provided with a bracket, and the dust bag is installed on the vacuum cleaner by installing the dust bag plate on the bracket.

[0004] However, the above-mentioned method of installing the dust bag has the following problems: the user may make mistakes when installing the dust bag, so that the dust bag cannot be stably installed on the vacuum cleaner. The dust bag may fall off during the operation of the vacuum cleaner, affecting the normal operation of the vacuum cleaner and posing certain safety hazards. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a vacuum cleaner which can prompt a user when the dust bag is correctly installed.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: a vacuum cleaner provided with a dust collecting bag, comprising: a shell, which defines a dust collecting chamber; a bracket, which is accommodated in the dust collecting chamber and is configured to rotate between a first position and a second position; a dust bag plate, on which the dust bag is mounted; the dust bag plate is configured to be movable on the bracket and is locked to the bracket by a locking mechanism when moving to the installation position, wherein the locking mechanism is provided on one of the bracket and the shell.

[0007] Furthermore, the locking mechanism includes a movable part, the movable part is installed on the bracket, the bracket includes a receiving portion, and the movable part is partially disposed in the receiving portion.

[0008] Furthermore, it further comprises a stopper provided corresponding to the movable part, and when the dust bag plate moves to the installation position, the stopper contacts the movable part.

[0009] Furthermore, the shifting member is arranged on the bracket, and the movable member includes a connecting part and a knocking part. When the dust bag plate is moved to the installation position by the user, the connecting part is connected to the dust bag plate, and the knocking part knocks the shifting member to generate a sound.

[0010] Furthermore, the locking mechanism further includes a limiting member, which is movably connected to the bracket and can be connected to the movable member.

[0011] Furthermore, the limiting member further includes a baffle, and when the dust bag plate and the bracket are in a separated state, the baffle pushes the movable member to move into the receiving portion.

[0012] Furthermore, a first elastic member is provided between the movable member and the bracket. When the dust bag plate is moved to the installation position by the user, the dust bag plate pushes the limiting member to move and separates the baffle from the movable member, so that the first elastic member pushes the movable member to move outside the receiving portion.

[0013] Furthermore, the limiting member further includes a sliding portion, and the bracket further includes a first sliding groove. The sliding portion can move along the first sliding groove, and the extending direction of the sliding portion is parallel to the installation direction of the dust bag plate.

[0014] Furthermore, the connecting portion is constructed as a hook, and the dust bag plate is correspondingly provided with an opening portion. When the dust bag plate is moved to the installation position by the user, the hook is connected to the opening portion.

[0015] Furthermore, it also includes a rotating member, and the bracket can rotate around the rotating member between a first position and a second position; a connecting member is arranged in the dust collecting chamber, and the connecting member can be connected to the dust bag plate; when the bracket moves from the second position to the first position, the connecting member pushes the movable member to separate from the dust bag plate, and the connecting member is connected to the dust bag plate.

[0016] Furthermore, it also includes: an operating member, which is operated by a user to switch between a first state and a second state; when the operating member is in the first state, the bracket is located in the first position; when the operating member is in the second state, the bracket drives the dust bag plate to move toward the second position together, so that the dust bag plate is separated from the connecting member, thereby separating the dust bag plate from the bracket.

[0017] Furthermore, the locking mechanism also includes a movable part, which is integrally formed on the bracket. The movable part also includes a matching end, which is connected to the bracket, and the movable part can rotate around the connection between the matching end and the bracket.

[0018] Furthermore, the locking mechanism includes a connecting piece, which is movably provided on the shell, and when the dust bag plate is in the installation position, the connecting piece is connected to the dust bag plate.

[0019] Furthermore, the connecting member is configured to move between an extended position and a retracted position. When the dust bag plate is in a separated state from the bracket, the connecting member is in the extended position. During the process of the dust bag plate being moved toward the installation position by the user, the dust bag plate pushes the connecting member to move toward the retracted position. When the dust bag plate moves to the installation position, the connecting member returns to the extended position and is connected to the dust bag plate.

[0020] Technical effects that can be achieved by the present invention

[0021] The vacuum cleaner of the present invention installs the dust bag on the vacuum cleaner through the dust bag plate. Specifically, the dust bag is installed on the dust bag plate, and a bracket is provided in the vacuum cleaner shell. When the dust bag needs to be installed, the user only needs to install the dust bag plate on the bracket to achieve the installation of the dust bag. At the same time, the vacuum cleaner is also provided with a movable part and a shifting part corresponding to the movable part. When the dust bag plate is moved to the installation position by the user, the connecting part of the movable part is connected to the dust bag plate, and the knocking part of the movable part knocks the shifting part to produce a sound. In this way, the user can judge whether the dust bag plate is correctly installed by whether he hears the knocking sound, thereby avoiding the failure of the dust bag to be stably installed due to user error.

[0042] The present invention will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0043] It should be understood that, in the description of the specific embodiments of the present invention, terms such as "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features being described. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features.

[0044] In the specific embodiments of the present invention, unless otherwise specified or limited, terms such as "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connections, movable connections, detachable connections, or integration; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0045] In a specific embodiment of the present invention, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but being in contact through another feature between them.

[0046] In the specific embodiments of the present invention, unless otherwise clearly defined and specified, the term "multiple" refers to two or more.

[0047] The vacuum cleaner provided with a dust bag of the present invention can be a handheld vacuum cleaner, a barrel vacuum cleaner, an upright vacuum cleaner or other cleaning devices using a dust bag. In the present embodiment, an upright vacuum cleaner is used as an example.

[0048] Please refer to Figures 1-20The vacuum cleaner comprises a vacuum device 1, a base 2, a floor brush assembly 3, a handle 4, and a hose 5. The vacuum device 1 is detachably mounted on the base 2. This allows the user to comprehensively clean the home floor with the floor brush assembly 3, resulting in high cleaning efficiency. Furthermore, if the user only needs to clean a small area or an area that is not suitable for the floor brush assembly 3, the user can remove the vacuum device 1 and hold it in hand for cleaning. This allows the user to choose the appropriate cleaning method based on the specific situation, allowing for faster cleaning of the home room and improving the user experience. The handle 4 is connected to the base 2 via a conduit 21. This allows the user to carry the vacuum cleaner with the handle 4 for cleaning, making cleaning more convenient. Furthermore, after the dust-laden airflow enters the base 2 from the floor brush assembly 3, it first passes through the conduit 21 and then enters the vacuum device 1 through the hose 5. It should be noted that in this embodiment, the floor brush assembly 3 is located above the base 2 and is connected to the base 2. The dust suction device 1 includes a working component, which can generate a dust suction airflow. In this embodiment, the working component at least includes an impeller and a motor for driving the impeller to rotate; the dust suction device 1 includes at least a first working state and a second working state. When the dust suction device is in the first working state, the dust suction device 1 is installed on the base 2, and the floor brush component works together with the dust suction device. The dust suction airflow enters the base 2 from the floor brush component 3 and enters the dust suction device 1 from the base 2, so that the user can quickly perform cleaning operations through the floor brush component 3; when the dust suction device 1 is in the second working state, the dust suction device 1 is separated from the base 2, and the dust suction airflow directly enters the dust suction device 1, so that the user can remove the dust suction device 1 from the base 2 as needed, and carry the dust suction device 1 for cleaning operations. It should be noted that, in other embodiments, the vacuum cleaner 1 also includes a third working state, and the handle is connected to a suction nozzle (not shown). When the vacuum cleaner 1 is in the third working state, the user can perform cleaning operations through the suction nozzle and the floor brush assembly 3 at the same time, thereby improving the cleaning efficiency.

[0049] The dust collecting device 1 includes a shell 11, which defines a dust collecting chamber 111. The shell 11 also includes a dust cover 112. The dust collecting device 1 also includes a switch 12. Through the switch 12, the user can directly remove the dust cover 112 to open the dust collecting chamber 111. Specifically, the switch 12 is provided on the dust cover 112, and the switch 12 includes a first connection end 121. Correspondingly, the shell 11 is provided with a second connection end 113. When the switch 12 is in the off state, the first connection end 121 is engaged with the second connection end 113. When the user needs to remove the dust cover 112, the user can lift the switch 12. At this time, the first connection end 121 and the second connection end 113 are disengaged, and the dust cover 112 is separated from the dust collecting device 1. In this embodiment, the first connection end 121 and the second connection end 113 are connected by a snap-fit method. Furthermore, the switch 12 further includes a first return member 122, which is specifically a spring in this embodiment. When the user removes the external force applied to the switch 12, the spring pushes the switch 12 back to its original position. It should be noted that the user lifting the switch 12 to remove the dust cover 112 is only one embodiment. In other embodiments, by making adaptive modifications to the first connection end 121 and the second connection end 113, the user can operate the switch 12 to remove the dust cover 112 in other ways, such as pressing the switch 12 or rotating the switch 12. The relevant content will not be repeated here.

[0050] The vacuum cleaner is provided with a dust bag 14. The dust collected by the vacuum cleaner is stored in the dust bag 14. When the dust bag is full of dust, the user can replace the dust bag with a new one and continue cleaning. Specifically, the dust bag 14 is provided in the dust collection chamber 111. In this embodiment, the dust bag 14 is installed in the dust cover 112. The dust cover 112 is also provided with an operating member 13. After the user removes the dust cover 112 from the dust collection device 1, the user can apply external force to the operating member 13 to make the dust bag 14 fall off. In this way, the user can remove the dust bag 14 from the dust cover 112 without directly touching the dust bag 14, and will not be contaminated by the dust on the dust bag 14, thereby improving the user experience. Furthermore, the operating member 13 is operated by a user to switch between a first state and a second state. When the operating member 13 is in the first state, the dust bag 14 remains stably mounted on the dust cover 112; when the operating member 13 is in the second state, the dust bag 14 is separated from the dust cover 112. It should be noted that the operating member 13 is not limited to only the first state and the second state. When the operating member 13 is acted upon by an external force, moves, and is positioned between the first state and the second state, the operating member 13 is in other states.

[0051] The vacuum cleaner further includes a dust bag plate 15, to which the dust bag 14 is mounted, and the dust bag plate 15 is detachably mounted on the dust cover 112. Specifically, the dust bag 14 is attached to the dust bag plate 15, and the dust bag 14 and the dust bag plate 15 are mounted together on the dust cover 112. After the dust bag 14 is full of dust, the user can carry the vacuum cleaner 1 to a trash can and apply external force to the operating member 13 to separate the dust bag plate 15 from the dust cover 112, allowing the dust bag plate 15 and the dust bag 14 to fall into the trash can together. The user then simply replaces the dust bag plate 15 with a new one to continue cleaning. It should be noted that the attachment of the dust bag 14 to the dust bag plate 15 is only a preferred embodiment. In other embodiments, the dust bag 14 and the dust bag plate 15 may also be detachably connected, and the user may only discard the dust bag 14 and recycle the dust bag plate 15.

[0052] The vacuum cleaner further includes a bracket 16, to which the dust bag plate 15 is detachably mounted. The bracket 16 is received in the dust collecting chamber 111 and mounted on the dust cover 112. When the operating member 13 is in the first state, the bracket 16 is connected to the operating member 13; when the operating member 13 is in the second state, the bracket 16 is separated from the operating member 13. Specifically, the bracket 16 includes a first hook 161, and the operating member 13 includes a second hook 131. When the operating member 13 is in the first state, the first hook 161 is connected to the second hook 131, so that the operating member 13 is snapped into the bracket 16. In a preferred embodiment, the first hook 161 and the second hook 131 are both constructed as hooks. It should be noted that, in other embodiments, the operating member 13 may also include a hook, and correspondingly, the bracket 16 may include a groove, and the hook is clamped in the groove to connect the operating member 13 and the bracket 16. Of course, the connection method between the operating member 13 and the bracket 16 may also be other snap-on methods, and is not limited to the above-mentioned connection method. The relevant content will not be repeated here.

[0053] The vacuum cleaner further includes a rotating member (not shown), the bracket 16 is connected to the rotating member, and the bracket 16 can rotate around the rotating member between a first position and a second position. When the operating member 13 is in the first state, the bracket 16 is located in the first position. Specifically, after the user installs the dust bag plate 15 on the bracket 16, the dust bag plate 15 can rotate around the rotating member together with the bracket 16; the housing 11 further includes a connecting member 114. When the bracket 16 is in the first position, the dust bag plate 15 installed on the bracket 16 is connected to the connecting member 114. In a preferred embodiment, the user can rotate the bracket 16 to the first position along the first direction m. At this time, the dust bag plate 15 is connected to the connecting member 114, the operating member 13 is in the first state, and the first hook 161 is connected to the second hook 13 1; the user applies an external force to the operating member 13 to switch the operating member 13 to the second state, the first hook 161 separates from the second hook 131, and the bracket 16 drives the dust bag plate 15 to move toward the second position together, so that the dust bag plate 15 is separated from the connecting member 114. At this time, the dust bag plate 15 is separated from the bracket 16 due to gravity; the user only needs to operate the operating member 13 to separate the dust bag 14 installed on the dust bag plate 15 from the dust cover 112 together with the dust bag plate 15, without directly contacting the dust bag 14.

[0054] Furthermore, in this embodiment, the rotating member includes a first conduit (not shown) and a second conduit (not shown), and the bracket 16 is disposed between the first conduit and the second conduit, and the bracket 16 is connected to the first conduit and the second conduit, respectively. Specifically, the bracket 16 includes a first shaft 162 and a second shaft 163, the first conduit being sheathed on the first shaft 162, and the second conduit being sheathed on the second shaft 163. In this way, the bracket 16 is mounted on the rotating member and can rotate around both the first and second conduits simultaneously. Of course, it should be noted that in other embodiments, the rotating member can also be a shaft, and the bracket 16 can include a conduit, and the conduit of the bracket 16 can be sheathed on the shaft of the rotating member. In this way, the bracket 16 can also rotate around the rotating member. The vacuum cleaner includes a second elastic member 18, which is disposed between the rotating member and the bracket 16, and one end of the second elastic member 18 is connected to the housing 11, and the other end is connected to the bracket 16. In this embodiment, at least one second elastic member 18 is provided in the shell 11, and preferably two, and the second elastic member 18 is configured as a torsion spring, so that the user pushes the bracket 16 along the first direction m to rotate the bracket 16 around the rotating member. When the bracket 16 rotates to the first position, the first hook 161 is engaged with the second hook 131. At this time, the operating member 13 is in the first state, the second elastic member 18 is in a twisted state, and the bracket 16 has a tendency to move toward the second position; when the operating member 13 is in the second state, the first hook 161 is separated from the second hook 131, and the second elastic member 18 returns to its original position and causes the bracket 16 and the dust bag plate 15 to move toward the second position together. It should be noted that the rotating member including the first conduit and the second conduit is only a preferred embodiment. In other embodiments, the rotating member can also be an integral body, and the rotating member is sleeved on the shaft of the bracket 16. The second elastic member 18 is provided between the bracket 16 and the rotating member. One end of the second elastic member 18 is connected to the bracket 16, and the other end is connected to the rotating member. In this way, when the bracket 16 rotates around the rotating member, the second elastic member 18 can also be in a twisted state, causing the bracket 16 to have a tendency to move toward the second position. It should be noted that the second elastic member 18 only needs to maintain one end connected to the bracket 16. The other end can be connected to the rotating member, or it can be connected to the housing 11, or it can be connected to other fixed structures located in the housing 11.At the same time, it should be noted that the first position is the position of the bracket 16 when the bracket 16 is connected to the operating member 13. In this embodiment, it is specifically the position where the bracket 16 is basically vertically arranged to the ground. The second position can be different from the first position and is not limited to the present embodiment. In other embodiments, the first position and the second position can also be selected according to the structural design of the vacuum cleaner.

[0055] Furthermore, the bracket 16 further includes a second sliding groove 164 , the dust bag plate 15 can move along the second sliding groove 164 , and the dust bag plate 15 includes an opening portion 151 , and the opening portion 151 can be connected to the connecting member 114 . Specifically, the bracket 16 is provided with two corresponding second sliding grooves 164. In the first embodiment of the present invention, the user can install the dust bag plate 15 on the bracket 16 through the second sliding grooves 164, and then the user pushes the bracket 16 to rotate along the first direction m; when the dust bag plate 15 is moved to the installation position along the second sliding grooves 164 by the user, and the bracket 16 is in the first position, the opening 151 is connected to the connecting member 114. At this time, the operating member 13 is in the first state, and the connecting member 114 can cooperate with the dust bag plate 15 to prevent the dust bag plate 15 from moving in the direction of gravity, so that the dust bag plate 15 and the dust bag 14 are stably installed on the dust cover 112; and when the operating member 13 is in the second state, the bracket 16 drives the dust bag plate 15 to move to the second position, thereby separating the opening 151 from the connecting member 114, so that the dust bag plate 15 moves downward along the second sliding grooves 164 due to gravity until it is separated from the bracket 16. In the first embodiment of the present invention, the connecting member 114 is fixedly disposed within the dust collecting chamber 111, and the connecting member 114 is configured as a protrusion, so that the opening 151 can engage with the protrusion. Of course, it should be noted that in the second embodiment of the present invention, the user can also first push the bracket 16 to rotate along the first direction m to the first position, and then install the dust bag plate 15 to the installation position through the second sliding groove 164. In this way, the dust bag can also be stably installed on the vacuum cleaner.

[0056] The operating member 13 is partially disposed in the dust collecting chamber 111 to be connected to the first hook 161, and partially disposed outside the dust collecting chamber 111 for user operation. Specifically, the operating member 13 includes a pressing portion 132 and a second return member (not shown). The pressing portion 132 is disposed outside the dust collecting chamber 111 for user operation, and the second hook 131 is at least partially disposed in the dust collecting chamber 111 to be connected to the first hook 161. The user can press the pressing portion 132 to move the operating member 13, thereby separating the second hook 131 from the first hook 161. The second return member is specifically constructed as a spring. When the user presses the pressing portion 132, the second return member is compressed. When the user removes the external force applied to the pressing portion 132, the second return member pushes the operating member 13 to return to its original position. It should be noted that unlocking the dust bag 14 by the user by pressing the pressing portion 132 is only one embodiment. In other embodiments, adaptive changes can be made to the first hook 161 and the second hook 131 to enable the user to unlock the dust bag 14 by rotating the operating member 13 or lifting the operating member 13. The relevant content will not be repeated here.

[0057] The vacuum cleaner further includes a locking mechanism, wherein the dust bag plate 15 is configured to be movable on the bracket 16 and locked to the bracket 16 by the locking mechanism when moving to the installation position, wherein the locking mechanism is provided on one of the bracket 16 and the housing 11 .

[0058] In the first embodiment of the present invention, the user first installs the dust bag plate 15 on the bracket 16 and then locks the bracket 16 to the housing 11. In this way, the dust bag plate 15 can be stably installed in the vacuum cleaner. In this embodiment, the locking mechanism is provided on the bracket 16 and includes a movable member 21 and a stop member 22 corresponding to the movable member 21. When the dust bag plate 15 moves to the installation position, the stop member 22 contacts the movable member 21. Specifically, the stopper 22 is disposed on the bracket 16. The movable member 21 includes a connecting portion 211 and a knocking portion 212. When the dust bag plate 15 is moved to the installation position by the user, the connecting portion 211 is connected to the dust bag plate 15 to prevent the dust bag plate 15 from moving in the direction of gravity. The knocking portion 212 knocks on the stopper 22, producing a sound to alert the user. This, on the one hand, prevents the dust bag 14 from being stably installed due to user error. On the other hand, after the user installs the dust bag 14 on the bracket 16, the dust bag 14 will not separate from the bracket 16, making it easier for the user to continue installing the dust bag 14 and improving the user experience. It should be noted that in this embodiment, the stopper 22 is integrally formed with the bracket 16. As a result, the structure of the vacuum cleaner is more compact and no additional space is required to install the stopper 22. Of course, in other embodiments, the stopper 22 can also be fixedly mounted within the vacuum cleaner housing, rather than being limited to being located on the bracket 16.

[0059] Furthermore, the connecting portion 211 is configured as a hook, and the opening 151 of the dust bag plate 15 cooperates with the hook to connect the movable member 21 and the dust bag plate 15. When the dust bag plate 15 is moved to the installation position by a user, the hook connects to the opening 151, and the dust bag plate 15 is stably mounted on the bracket 16. Thereafter, the user can rotate the bracket 16 along the first direction m to the first position. At this time, the connecting member 114 pushes the connecting portion 211 to separate from the opening 151, and the connecting member 114 is connected to the dust bag plate 15. The operating member 13 is in the first state, and the first hook 161 is connected to the second hook 131, thereby stably mounting the dust bag plate 15 on the vacuum cleaner.

[0060] The movable member 21 is mounted on the bracket 16. The bracket 16 includes a receiving portion 165, and the movable member 21 is partially disposed within the receiving portion 165. Specifically, the movable member 21 further includes a rotating shaft 214, which is disposed within the receiving portion 165 and connected to the bracket 16, thereby rotatably connecting the movable member 21 to the bracket 16. The locking mechanism further includes a limiting member 23, which is movably connected to the bracket 16 and can be connected to the movable member 21. Specifically, a first elastic member 24 is provided between the movable member 21 and the bracket 16, and the movable member 21 also includes a mating end 213, and the first elastic member 24 is provided between the bracket 16 and the mating end 213; the limiting member 23 also includes a baffle 232, and when the dust bag plate 15 and the bracket 16 are in a separated state, the baffle 232 pushes the movable member 21 to move into the receiving portion 165, and makes the first elastic member 24 in a compressed state; when the dust bag plate 15 is moved to the installation position by the user, the dust bag plate 15 pushes the limiting member 23 to move, and makes the baffle 232 separate from the movable member 21, and the first elastic member 24 pushes the movable member 21 to move out of the receiving portion 165, so that the connecting portion 211 is connected to the dust bag plate 15. In a preferred embodiment, the baffle 232 can compress the connecting portion 211 so that the movable part 21 has a tendency to move into the receiving portion 165, and the first elastic part 24 is in a compressed state. It should be noted that in other embodiments, the baffle 232 is not limited to being connected to the connecting portion 211 of the movable part 21, but can also be in contact with other parts of the movable part 21 to push the movable part 21 to move into the receiving portion 165.

[0061] Furthermore, it should be noted that the installation of the movable part 21 on the bracket 16 is only one embodiment. In other embodiments, the movable part 21 can also be integrally formed on the bracket 16, and in this case, the matching end of the movable part 21 is connected to the bracket, and the movable part 21 can rotate around the connection between the matching end and the bracket 16. Specifically, the movable member 21 is made of elastic material, so that when the dust bag plate 15 and the bracket 16 are in a separated state, the limiting portion 23 pushes the movable member 21 to move into the receiving portion 165. At this time, the movable member 21 undergoes elastic deformation, so that the connecting portion 211 of the movable member 21 has a tendency to move out of the receiving portion 165, and the knocking portion 212 of the movable member 21 has a tendency to move toward the stop member 22; and when the dust bag plate 15 is moved to the installation position by the user, the dust bag plate 15 pushes the limiting member 23 to move and separate the limiting member 23 from the movable member 21, so that the movable member 21 returns to its original state and rotates around the connection between the mating end and the bracket 16, so that the connecting portion 211 moves out of the receiving portion 165, and the knocking portion 212 moves toward the stop member 22 and knocks on the stop member 22 to issue a prompt.

[0062] The limiting member 23 further includes a sliding portion 231. The bracket 16 is provided with a first sliding groove 166. The sliding portion 231 can move along the first sliding groove 166. In a preferred embodiment, the extension direction of the sliding portion 231 is parallel to the installation direction of the dust bag plate 15. In this way, the limiting member 23 and the movable member 21 can cooperate more stably and save more space. The vacuum cleaner also includes a third return member 233. The third return member 233 is preferably a spring, and the third return member 233 is connected to the limiting member 23. Please refer to the specific Figure 11-14 , the user has not installed the dust bag 14. At this time, the baffle 232 continuously presses the movable member 21 so that the movable member 21 has a tendency to move into the receiving portion 165, and the first elastic member 24 is in a compressed state. Please continue to refer to Figure 15-18 When the dust bag plate 15 is moved to the installation position by the user, the dust bag plate 15 pushes the limiting member 23 to move along the installation direction of the dust bag plate 15. At this time, the third restoring member 233 is compressed, and the baffle 232 is separated from the movable member 21. The first elastic member 24 pushes the movable member 21 to move out of the receiving portion 165. In this way, the connecting portion 211 is connected to the opening portion 151 of the dust bag plate 15. The knocking portion 212 knocks the baffle member 22 to make a knocking sound, so that the user can know that the dust bag 14 has been correctly installed. Please continue to refer to 19- Figure 20The bracket 16 is rotated from the second position to the first position by the user. At this time, the connecting member 114 pushes the connecting portion 211 to separate from the opening 151 of the dust bag plate 15, and the connecting member 114 is connected to the opening 151 of the dust bag plate 15. At the same time, the first hook 161 is connected to the second hook 131 through a buckle. In this way, the operating member 13 is in the first state, and the dust bag 14 is stably installed on the vacuum cleaner. Please refer to Figure 11-14 The user applies an external force to the operating member 13 to rotate the operating member 13 from the first state to the second state. At this time, the first hook 161 is disengaged from the second hook 131, and the bracket 16 moves from the first position to the second position. The connecting member 114 is separated from the opening 151 of the dust bag plate 15. As a result, the dust bag plate 15 is separated from the bracket 16 due to gravity, and the third restoring member 233 returns to its original position and pushes the limiting member 23 to move in the opposite direction of the installation direction of the dust bag plate 15, so that the baffle 232 cooperates with the movable member 21 again to keep the movable member 21 in the receiving portion 165.

[0063] In the second embodiment of the present invention, the user first locks the bracket 16 to the housing 11, and then installs the dust bag plate 15 on the bracket 16, so that the dust bag plate 15 can be stably installed on the vacuum cleaner. In this embodiment, the locking mechanism is provided on the housing 11, and the locking mechanism includes a connecting member 114. Different from the first embodiment, the connecting member 114 of this embodiment can be movably provided on the housing. When the dust bag plate 15 is in the installation position, the connecting member 114 is connected to the dust bag plate 15. Specifically, the connecting member 114 is configured to move between an extended position and a retracted position. In this embodiment, an elastic unit (not shown) is further provided between the connecting member 114 and the housing 11. When the connecting member 114 is in the retracted position, the elastic unit is compressed, and the connecting member 114 has a tendency to return to the extended position. When the user needs to install the dust bag 14, he or she must first rotate the bracket 16 along the first direction m to the first position, and then install the dust bag plate 15 onto the bracket 16 from below the bracket 16. Specifically, when the dust bag plate 15 is separated from the bracket 16, the connecting member 14 is in the extended position. During the process of the dust bag plate 15 being moved toward the installation position by the user, the dust bag plate 15 pushes the connecting member 14 toward the retracted position, thereby compressing the elastic unit. When the dust bag plate 15 moves to the installation position, the connecting member 14 returns to the extended position and connects to the opening 151 of the dust bag plate 15. In this way, the dust bag plate 15 is stably installed on the vacuum cleaner.
