Description

Technical Field

[0001] This utility model relates to the field of cleaning technology, and in particular to a cleaning device. Background Technology

[0002] Handheld vacuum cleaners are commonly used for cleaning dust from object surfaces. These vacuum cleaners generally include a fan, a separator, and a dust cup, with the separator located inside the dust cup. When the vacuum cleaner is working, the dust is separated by the separator under the force of the fan, and most of the dust is collected in the dust cup. Although existing handheld vacuum cleaners have an openable bottom for the dust cup to facilitate emptying, dust has a strong adsorption capacity, and users often cannot empty it completely by hand, and dust can easily splatter, causing secondary pollution. Therefore, some vacuum cleaners now use a tray to collect the dust from the dust cup.

[0003] Besides collecting dust from the dust cup on the vacuum cleaner, the tray typically also needs to store vacuum cleaner heads, such as vacuum hoses and floor brushes. However, there are generally two types of holders used for storing vacuum cleaner heads: one is a separate mounting bracket, which requires users to repeatedly remove and replace the bracket along with the heads when frequently changing them, making it inconvenient; the other is a one-piece design at the bottom of the tray, where the bracket cannot be removed. If users don't need to change the heads, these attachments and the non-removable bracket make the tray bulky and take up a lot of space. Furthermore, because the bracket is located at the bottom of the tray, the heads are stored too low, requiring users to bend over to retrieve them, which is also inconvenient. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a cleaning device that can take into account the usage habits of different users, has a wide range of applications, and is easy to use.

[0005] This utility model is achieved through the following technical solution:

[0006] A cleaning device includes a vacuum cleaner, the vacuum cleaner comprising a handheld component, a connecting rod, and at least two cleaning heads, one end of the connecting rod being coupled to the vacuum cleaner and the other end being selectively coupled to one of the cleaning heads; the cleaning device further includes:

[0007] The tray includes a connector, a chassis, and a support rod for connecting the connector and the chassis. The connector is configured to engage with the handheld assembly, and the chassis is configured to support the vacuum cleaner.

[0008] A mounting bracket on which the cleaner head is detachably mounted;

[0009] A locking mechanism is provided, wherein the fixing frame and the support rod are detachably fixed by the locking mechanism, and a notch is formed on the fixing frame, the notch being oriented toward the support rod, and when the fixing frame and the support rod are fixed, the support rod is at least partially accommodated in the notch.

[0010] Furthermore, when the fixing frame is fixed to the support rod, the fixing frame is at least partially overlapped with the chassis in the axial direction.

[0011] Furthermore, the locking mechanism is positioned near the notch / groove.

[0012] Furthermore, the fixing bracket is detachably mounted on the support rod on the side near the connecting head.

[0013] Furthermore, the locking mechanism includes an elastic element and a locking block, one end of the elastic element abutting against the fixed frame and the other end abutting against the locking block, and the locking block is slidably disposed on the fixed frame and is at least partially exposed from the notch.

[0014] Furthermore, a sliding groove is formed on the fixing frame, one end of the elastic member abuts against the bottom wall forming the sliding groove, the locking block is at least partially disposed in the sliding groove and can reciprocate along the direction of the sliding groove, an opening is formed on the side wall forming the notch, and the locking block at least partially passes through the opening.

[0015] Furthermore, the locking block includes a protrusion located at the end of the locking block, and the locking block has a first position and a second position;

[0016] When the locking block is in the first position, the protrusion is at least partially exposed from the opening within the notch groove;

[0017] When the locking block is in the second position, the protrusion does not protrude from the side wall.

[0018] Furthermore, the locking block also includes a sliding block, which is disposed in the sliding groove, and when the locking block is in the first position, the sliding block abuts against the side wall.

[0019] Furthermore, a first inclined surface is formed on the protrusion. During the installation of the support rod and the fixing frame, the support rod abuts against the first inclined surface and slides relative to it, and the locking block moves against the elastic force of the elastic element.

[0020] Furthermore, a second inclined surface is formed on the protrusion. During the disassembly of the support rod and the fixing frame, the support rod abuts against the second inclined surface and slides relative to it, and the locking block moves against the elastic force of the elastic element.

[0021] Furthermore, the locking mechanism also includes a cover plate configured to close the sliding groove to prevent the locking block from disengaging from the sliding groove.

[0022] Furthermore, the support rod is provided with a positioning protrusion. When the fixing frame is fixed to the support rod, the fixing frame is located on one side of the positioning protrusion and abuts against the positioning protrusion.

[0023] Furthermore, a limiting platform is formed on the cover plate. When the fixing frame is fixed to the support rod, the limiting platform is located on the other side of the positioning protrusion and abuts against the positioning protrusion.

[0024] Furthermore, a third inclined surface is formed on the limiting platform, and the third inclined surface is configured to guide the positioning protrusion.

[0025] Furthermore, the limiting platform has an upper constitutive surface, and the side wall forming the notch has a lower constitutive surface. The upper constitutive surface and the lower constitutive surface together form the positioning protrusion motion trajectory groove.

[0026] Furthermore, the upper and lower constituent surfaces have oppositely arranged inclined surfaces, the positioning protrusion extends perpendicular to the axial direction and has a wedge shape that is larger inside and smaller outside, and simultaneously cooperates with the upper and lower constituent surfaces.

[0027] Furthermore, the shape of the positioning protrusion matches the shape of the support rod and is configured with a C-shaped opening.

[0028] Furthermore, the protrusion has a first segment arranged in a front-back direction and a second segment that gradually tapers in an arc shape, extending parallel to the Y-axis direction of the support rod, and the width remains consistent in the extension direction.

[0029] Furthermore, there are two locking mechanisms, which are symmetrically arranged along the center line of the fixing frame.

[0030] Furthermore, the cross-section of the support rod is approximately elliptical, and the support rod has a first arc surface. An arc-shaped portion matching the first arc surface is formed on the notch. When the fixing frame and the support rod are connected, the first arc surface fits into the arc-shaped portion.

[0031] Furthermore, the support rod also has a second arc surface, and the first arc surface and the second arc surface are both similar to semicircles and are symmetrically arranged, with the openings of the first arc surface and the second arc surface being arranged opposite to each other.

[0032] Furthermore, the tray is equipped with a dust collection station, which contains a waste collection chamber and a second vacuum motor. The connecting head is connected to the dust cup of the vacuum cleaner. The support rod is equipped with a recycling channel that connects the connecting head and the waste collection chamber, thereby enabling the second vacuum motor to suck the waste from the dust cup into the waste collection chamber.

[0033] Compared with existing technologies, the advantages of this utility model are:

[0034] 1. This utility model innovatively makes the fixing frame and tray detachable. When users do not need to frequently change the cleaning head, the fixing frame can be removed from the tray for separate storage, thereby reducing the footprint of the cleaning equipment. When users need to change the cleaning head, the fixing frame can be installed on the tray for quick access to the cleaning head, while also taking into account the usage habits of different users, making it widely applicable.

[0035] 2. By detachably mounting the fixing bracket on the support rod near the connecting head and positioning it close to the user's waist, the cleaning head can be easily accessed by the user, reducing the inconvenience caused by bending over.

[0036] 3. By setting a positioning protrusion on the support rod and a corresponding limiting platform on the fixed frame, the combined action of the limiting platform and the fixed frame defines the movement trajectory groove of the positioning protrusion. This allows the positioning protrusion to abut against the fixed frame and slide relative to the limiting platform, thus providing a guiding function. After the fixed frame and support rod are connected, the positioning protrusion is fixed between the fixed frame and the limiting platform, providing support for the fixed frame and preventing it from slipping due to gravity or tipping over due to external forces.

[0048] The following detailed, non-limiting description of the utility model's technical solution, in conjunction with preferred embodiments and accompanying drawings, is provided. In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0049] like Figures 1 to 10 As shown, an embodiment of this utility model provides a cleaning device including a vacuum cleaner 4. The vacuum cleaner 4 is a handheld vacuum cleaner and includes a handheld component 40, a connecting rod 41, and at least two cleaning heads 5. One end of the connecting rod 41 is connected to the vacuum cleaner 4, and the other end can be selectively connected to one of the cleaning heads 5. Specifically, the handheld component 40 includes a vacuum motor, a dust cup 401 for collecting debris, and a fluid channel. The connecting rod 41 has an internal channel connecting the handheld component 40 and the fluid channel within the cleaning head 5, allowing the handheld component 40 to draw dust into the dust cup 401 through the cleaning head 5 and the connecting rod 41. Of course, the vacuum cleaner 4 also has other usage modes, such as using only the handheld component 40 and the connecting rod 41, or using the handheld component 40 directly connected to the cleaning head 5. The cleaning head 5 can be a dusting brush head, a round brush head, a mite removal brush head, a carpet brush head, etc. Users can select one of the cleaning heads 5 and install it on the vacuum cleaner 4, thus adapting to more usage scenarios.

[0050] Because the handheld assembly 40 houses relatively heavy components such as the vacuum motor, the head of the vacuum cleaner 4 is quite heavy. This makes it difficult to maintain its upright position when the handheld assembly 40, connecting rod 41, and cleaning head 5 are connected. Therefore, a tray 1 is provided to support the vacuum cleaner 4. See details in [reference needed]. Figure 1 The tray 1 has a connector 10 for connecting the handheld assembly 40, a base 13 fixed to the ground, and a support rod 11 connecting the two. (See also...) Figure 10 The chassis 13 has a bottom surface that is larger than the vertical projection area of ​​the vacuum cleaner 4, so that the vacuum cleaner 4 can be stored upright.

[0051] In some embodiments, the handheld assembly 40 is provided with a battery pack for powering components such as the vacuum motor and the roller brush motor. The connector 10 also has a coupler electrically connected to the handheld assembly 40, and the tray 1 is also provided with a connector electrically connected to the handheld assembly 40 for charging the battery pack, further facilitating user operation.

[0052] Furthermore, although the bottom of the dust cup 401 is designed to be openable for emptying, the dust inside has a strong adsorption capacity, making it difficult for users to empty completely by hand, and dust can easily splatter and cause secondary pollution. Therefore, in some embodiments, the tray 1 is also equipped with a dust collection station 12 for collecting the dust in the dust cup 401. Specifically, the dust collection station 12 is equipped with a dust collection chamber and a second vacuum motor. The connecting head 10 is connected to the dust cup 401 of the vacuum cleaner 4, and the support rod 11 is equipped with a collection channel that connects the connecting head 10 and the dust collection chamber, allowing the second vacuum motor to suck the dust from the dust cup 401 into the dust collection chamber. This design allows users to clean the dust cup 401 while storing the vacuum cleaner 4 after use, greatly simplifying the user experience.

[0053] Furthermore, the cleaning equipment also includes a holder 2 for storing excess cleaning heads 5. It is worth noting that because the upper part of the tray 1 needs to engage with the handheld component 40, the user desires to retain the attachment head 10 at the top, which is already quite large, making it unsuitable to store it further at the top of the tray 1. Additionally, the user does not want excessive bending. Therefore, the holder 2 is detachably mounted on the support rod 11 near the attachment head 11, and positioned close to the user's waist for easy access to the cleaning heads 5.

[0054] Preferably, the cleaning equipment also includes a locking mechanism 3, and the fixing frame 2 and the tray 1 are detachably connected via the locking mechanism 3. When the user does not need to frequently change the cleaning head 5, the fixing frame 2 can be removed from the tray 1 for separate storage, thereby reducing the footprint of the cleaning equipment. When the user needs to change the cleaning head 5, the fixing frame 2 can be installed on the tray 1 for quick access to the cleaning head 5, while also taking into account the usage habits of different users, making it widely applicable.

[0055] Further reference Figure 2 The mounting bracket 2 is equipped with various fixing structures to allow multiple cleaning heads 5 to be detachably mounted on it. In this embodiment, three support columns 23 are provided at the top of the mounting bracket 2 for fixing smaller cleaning heads 5, such as round brushes, and a slot 25 is provided at the bottom for fixing larger cleaning heads 5, such as floor brushes. A notch 22 is also provided at one corner of the mounting bracket 2 for accommodating tubular cleaning heads 5, such as flexible hoses. These various fixing structures are respectively located at the four corners of the mounting bracket 2, allowing the mounting bracket 2 to accommodate multiple cleaning heads 5 without interfering with each other.

[0056] Key reference Figures 3 to 5The fixing frame 2 has a notch 20 formed on it, and the notch 20 is oriented towards the support rod 11. When the fixing frame 2 is fixed to the support rod 11, the support rod 11 is at least partially accommodated in the notch 20. The locking mechanism 3 includes an elastic element 30 and a locking block 31. One end of the elastic element 30 abuts against the fixing frame 2, and the other end abuts against the locking block 31. The locking block 31 is slidably disposed on the fixing frame 2 and is at least partially exposed from the notch 20. That is, when the support rod 11 is engaged in the notch 20, the locking block 31, under the action of the elastic element 30, at least partially protrudes from the notch 20 to prevent the support rod 11 from disengaging from the notch 20, thereby fixing the fixing frame 2 to the support rod 11. When disassembly is required, the locking block 31 can overcome the action of the elastic element 30 and move, no longer obstructing the support rod 11, thereby realizing the detachable connection between the fixing frame 2 and the support rod 11.

[0057] Optionally, the cross-section of the support rod 11 is approximately elliptical, and the support rod 11 has a first arc surface 110, a second arc surface 113, and a parallel portion 114. An arc-shaped portion 203 matching the first arc surface 110 is formed on the notch 20. When the fixing frame 2 and the support rod 11 are connected, the first arc surface 110 fits against the arc-shaped portion 203, improving the overall aesthetic effect and preventing the fixing frame 2 from tilting.

[0058] Furthermore, a sliding groove 21 is formed on the fixing frame 2, one end of the elastic member 30 abuts against the bottom wall 210 forming the sliding groove 21, and the locking block 31 is disposed in the sliding groove 21 and can reciprocate along the direction of the sliding groove 21. An opening 202 is formed on the side wall 201 forming the notch 20, and the locking block 31 passes through the opening 202 at least partially. In this embodiment, the elastic member 30 is preferably a spring.

[0059] Preferred, refer to Figure 5 The locking block 31 includes a sliding block 313 and a protrusion 310 connected to each other. The protrusion 310 is located at the end of the locking block 31, and the other end of the elastic member 30 abuts against the sliding block 313. The locking block 31 has a first position and a second position. When the locking block 31 is in the first position, the protrusion 310 is at least partially exposed in the notch 20 from the opening 202 to prevent the support rod 11 from disengaging from the notch 20. When the locking block 31 is in the second position, the protrusion 310 does not protrude from the side wall 201, so that the support rod 11 can disengage from the notch 20. This allows for the assembly and disassembly of the support rod 11 from the fixing frame 2. The sliding block 313 is disposed in the sliding groove 21, and when the locking block 31 is in the first position, the sliding block 313 abuts against the side wall 201 to limit the locking block 31 and prevent the locking block 31 from disengaging from the sliding groove 21.

[0060] In detail, the locking block 31 is initially in the first position. When it is necessary to fix the fixing frame 2 to the tray 1, the user can connect the fixing frame 2 to the support rod 11. The support rod 11 has an axis in the Z direction, which is also the direction of internal fluid movement. The fixing frame 2 moves in a plane perpendicular to the axis Z direction to connect with the support rod 11. During the connection process, firstly, the first arc surface 110 on the support rod 11 abuts against and slides relative to the protrusion 310, thereby pushing the locking block 31 to move to the second position against the elastic member 30. Then, the parallel part 114 abuts against and slides relative to the protrusion 310, and the locking block 31 remains in the second position without affecting the movement of the fixing frame 2. Finally, the second arc surface 113 abuts against and slides relative to the protrusion 310. At this time, the locking block 31 moves towards the first position under the action of the elastic member 30. When the first arc surface 110 is in contact with the arc-shaped portion 203, the locking block 31 moves to the first position. At this time, the locking block 31 is still in contact with the second arc surface 113, and under the combined action of the notch groove 20, it limits the support rod 11, thereby realizing the installation of the fixing frame 2 and the support rod 11. Similarly, the movement of the locking block 31 is the same when disassembling.

[0061] Furthermore, the first arc surface 110 and the second arc surface 113 are both similar to semicircles and are symmetrically arranged. At the same time, the openings of the first arc surface 110 and the second arc surface 113 are arranged opposite each other. On the one hand, this can ensure the stability of the locking block 31 during movement, and on the other hand, it can ensure the contact of the locking block 31, thus preventing the fixing between the fixing frame 2 and the support rod 11 from failing.

[0062] Optionally, a first inclined surface 311 is formed on the protrusion 310 to guide the connection between the fixing frame 2 and the support rod 11. During the installation of the support rod 11 and the fixing frame 2, the support rod 11 abuts against and slides relative to the first inclined surface 311, thereby pushing the locking block 31 to move against the elastic force of the elastic member 30. The design of the first inclined surface 311 makes it easier for the user to assemble the fixing frame 2 and can improve its service life.

[0063] Similarly, a second inclined surface 312 is formed on the protrusion 310 to guide the fixing frame 2 when it is disassembled from the support rod 11. During the disassembly of the support rod 11 from the fixing frame 2, the support rod 11 abuts against the second inclined surface 312 and slides relative to it, thereby pushing the locking block 31 to move against the elastic force of the elastic member 30.

[0064] Optionally, each sliding block 313 has a limiting protrusion 301 formed thereon, and one end of the elastic element 30 is sleeved on the limiting protrusion 301 to prevent the elastic element 30 from being misaligned and causing the locking block 31 to fail to move.

[0065] In addition, the locking mechanism 3 also includes a cover plate 32, which is configured to cover the sliding groove 21 to prevent the locking block 31 from disengaging from the elastic member 30. Specifically, the cover plate 32 is fixed to the fixing bracket 2 by screws, and an annular recess 320 is formed on the cover plate 32 facing the elastic member 30 to guide the elastic member 30, so that it can move along the annular recess 320 when deformed, thereby improving the stability of the locking block 31 during movement.

[0066] Further reference Figures 6 to 9 The support rod 11 has a protruding positioning protrusion 112, and the cover plate 32 has a limiting platform 321. When the fixing frame 2 is fixed to the support rod 11, the fixing frame 2 is located on one side of the positioning protrusion 112 and abuts against the positioning protrusion 112, while the limiting platform 321 is located on the other side of the positioning protrusion 112 and abuts against the positioning protrusion 112. In detail, during the connection between the fixing frame 2 and the support rod 11, the positioning protrusion 112 abuts against the fixing frame 2 and slides relative to the limiting platform 321, thereby playing a guiding role. After the fixing frame 2 and the support rod 11 are connected, the positioning protrusion 112 is fixed between the fixing frame 2 and the limiting platform 321 to support the fixing frame 2 and prevent the fixing frame 2 from slipping due to gravity.

[0067] Important reference Figure 7 The upper surface C1 of the limiting platform 321 has an inclined surface, and the lower surface C2 of the side wall 201 forming the notch 20 also has an inclined surface. The upper surface C1 and the lower surface C2 together form the movement trajectory groove of the positioning protrusion 112. In addition to limiting the movement trajectory of the fixing frame 2, the upper surface C1 is used to support the fixing frame 2, and the lower surface C2 is used to prevent the fixing frame 2 from being overturned by force during the installation and removal of the cleaner head 5 in the slot 25 of the fixing frame 2.

[0068] Furthermore, the positioning protrusion 112 extends perpendicularly to the Z-axis and has a wedge-shaped (larger inside and smaller outside) design, facilitating its engagement with the groove formed by the upper component surface C1 and the lower component surface C2. (See also...) Figure 8 In this embodiment, the positioning protrusion 112 is C-shaped and matches the shape of the support rod 11, and has a second segment 112b that gradually tightens in an arc shape and a first segment 112a that is arranged in the front-back direction.

[0069] It is understood that in other alternative embodiments, the positioning protrusion 112 may not match the shape of the support rod 11. Similarly, the positioning protrusion 112 may be arranged in a circle, in an open shape, or discontinuously, that is, there may be other arrangements besides the C-shaped arrangement shown in this embodiment.

[0070] Furthermore, in this embodiment, the first segment 112a extends parallel to the Y-axis direction of the support rod 11, and the width of the extension direction is consistent. Alternatively, it can extend at an angle to the Y-axis direction, but it must ensure that... Figure 8 In the example direction, i.e., the Z-axis, the positioning protrusion 112 is wider on the left and narrower on the right in the left-right direction.

[0071] Optionally, a third inclined surface 322 is formed on the limiting platform 321, which serves to guide the positioning protrusion 112. Specifically, the positioning protrusion 112 first abuts against the third inclined surface 322 and slides relative to it, and then moves to abut against both the fixing frame 2 and the limiting platform 321 at the same time, so that the user can quickly connect the fixing frame 2 and the support rod 11.

[0072] In addition, we should focus on referring to Figure 4 The aforementioned locking mechanism 3 is provided in two parts, symmetrically arranged along the center line X of the fixing frame 2, to improve the locking effect when the fixing frame 2 is fixed to the support rod 11. Simultaneously, since the fixing frame 2 needs to be fixed to the support rod 11, to avoid excessive pressure on the support rod 11 due to the weight of the fixing frame 2, the fixing frame 2 is designed with a hollowed-out shape and reinforced with reinforcing ribs 24 to strengthen its strength. (Refer to...) Figure 10 When the fixing frame 2 is fixed to the support rod 11, in the Z-axis direction, most of the fixing frame 2 coincides with the chassis 13, so as to reduce the storage space.

[0073] The usage process of the cleaning equipment provided by this utility model is as follows: The locking block 31 is initially in the first position. When it is necessary to fix the fixing frame 2 and the tray 1, the user can move the fixing frame 2 in a plane direction perpendicular to the axis Z to engage with the support rod 11. During the engagement process, firstly, the first arc surface 110 on the support rod 11 abuts against and slides relative to the first inclined surface 311 on the protrusion 310, thereby pushing the locking block 31 to move to the second position against the elastic member 30. Then, the parallel part 114 abuts against and slides relative to the protrusion 310, and the locking block 31 remains in the second position, without affecting the movement of the fixing frame 2. Finally, the second arc surface 113 abuts against and slides relative to the second inclined surface 312 of the protrusion 310. At this time, the locking block 31 moves towards the first position under the action of the elastic member 30. When the first arc surface 110 is in contact with the arc-shaped part 203, the locking block 31 moves to the first position and remains in contact with the first arc surface 110. Under the combined action of the notch groove 20, it limits the support rod 11, thereby realizing the installation of the fixing frame 2 and the support rod 11. The same principle applies to disassembly.

[0074] This utility model innovatively makes the fixing frame 2 and the integrated base station 1 detachable. When the user does not need to frequently replace the cleaner head 5, the fixing frame 2 can be removed from the tray 1 for separate storage, thereby reducing the footprint of the cleaning equipment. When the user needs to replace the cleaner head 5, the fixing frame 2 can be installed on the tray 1 for quick access to the cleaner head 5, while also taking into account the usage habits of different users, making it widely applicable.

[0075] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
