Description

Technical Field

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

[0002] Typically, the handheld component and body of a handheld vacuum cleaner can be freely disassembled and assembled by the user, with the wiring between them connected via a coupler. The male and female terminals of the coupler are completely fixed to the body and handheld components, respectively, and together they form a conductive circuit. However, often when users assemble the handheld and body components and use the floor brush to clean the floor, the back-and-forth dragging of the handle may cause the male and female terminals of the coupler to loosen, resulting in poor contact and causing the entire machine to malfunction. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a cleaning device that solves the problem of poor contact between the handheld component and the main body component during user operation.

[0004] This utility model is achieved through the following technical solution:

[0005] A cleaning device includes a handheld component and a body component detachably connected to the handheld component. The handheld component has a first coupler, and the body component has a second coupler pluggable and detachable to the first coupler. The handheld component comprises:

[0006] An air inlet duct is provided with a mounting cavity with an opening on one side facing forward. The mounting cavity is used to install the first coupler.

[0007] The housing unit has a duct cover plate that covers the opening of the mounting cavity, and the duct cover plate has a through hole to expose the first coupler.

[0008] The adapter plate has the first coupler fixed on it. The adapter plate is disposed in the mounting cavity and can move back and forth along the axial direction of the air inlet duct.

[0009] Furthermore, the inner wall of the mounting cavity is provided with a protruding rib, which is used to limit the side of the adapter plate away from the first coupler.

[0010] Furthermore, there is a gap between the side of the adapter plate closest to the first coupler and the duct cover plate.

[0011] Furthermore, the adapter plate is provided with a raised rib on the side where the first coupler is located, and there is a gap between the raised rib and the air duct cover plate.

[0012] Furthermore, the duct cover plate is recessed inward to form a first clearance groove corresponding to the position of the raised rib.

[0013] Furthermore, the first coupler is at least partially located within the through hole.

[0014] Furthermore, the inner wall of the mounting cavity is provided with a pair of studs for mounting and positioning the air duct cover plate, and the two ends of the adapter plate extend outward to form hanging arms, which are mounted on the corresponding studs.

[0015] Furthermore, the end of the hanging arm facing the stud has an arc-shaped surface.

[0016] Furthermore, there is a gap between the sidewall of the adapter plate and the corresponding stud.

[0017] Furthermore, there is a gap between the upper part of the adapter plate and the air inlet duct, and a gap between the lower part of the adapter plate and the inner bottom wall of the mounting cavity.

[0018] Furthermore, the upper part of the adapter plate is recessed inward to form a second clearance groove.

[0019] Furthermore, the handheld assembly also includes a dust cup unit, the housing unit extends forward to connect to the air inlet duct, the rear part of the air inlet duct extends into the housing unit and is in fluid communication with the dust cup unit, and the dust cup unit is horizontally positioned and located below the air inlet duct;

[0020] The bottom of the air inlet duct protrudes downwards to form the mounting cavity, and the dust cup unit has a notch that fits the mounting cavity.

[0021] Furthermore, the front of the dust cup unit is provided with a cup lid, and the notch is located on the upper part of the dust cup unit and close to the cup lid.

[0022] Furthermore, a pivot and a torsion spring for rotating the cup lid are provided at the notch, and a cup lid lock is provided on the opposite side of the notch.

[0023] Compared with existing technologies, the advantages of this utility model are:

[0024] 1. The adapter plate with the first coupler inside the handheld assembly is designed to float. The adapter plate is housed within the mounting cavity and can move back and forth along the axis of the air inlet duct. When the second coupler of the main unit moves forward, the adapter plate drives the first coupler forward synchronously, maintaining a tight fit between the first and second couplers and preventing functional loss due to poor contact. The floating design provides a certain tolerance to improve the stability and reliability of the connection between the first and second couplers, preventing the coupler from loosening and affecting functionality when the user holds the handheld assembly and moves the entire unit back and forth.

[0025] 2. In this utility model, the adapter plate is not fastened to the two studs by closed holes on both sides. Instead, two hanging arms are designed to rest on the studs. At the same time, a small gap is left between the adapter plate and the outer wall of the air duct and the inner bottom wall of the mounting cavity. Therefore, the adapter plate can have a certain floating space in the left and right and up and down directions in the mounting cavity. When the first coupler and the second coupler are slightly misaligned, they can float and align themselves. Attached Figure Description

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.

[0041] like Figure 1-13As shown, a cleaning device according to an embodiment of the present invention includes a handheld component 1 and a body component detachably connected to the handheld component 1. Users can use the handheld component 1 alone for cleaning, or install the handheld component 1 on the body component for floor cleaning, etc., according to the usage scenario and needs.

[0042] In this application, such as Figure 1 As shown, the front-to-back direction is the X direction, which is the horizontal direction of the handheld component 1; the left-to-right direction is the Y direction; and the up-to-down direction is the Z direction, which is the vertical direction of the handheld component 1.

[0043] The handheld component 1 includes a housing unit 10, a dust cup unit 20, and a motor unit 30. The dust cup unit 20 and the motor unit 30 are arranged front and rear, respectively, and are both mounted on the housing unit 10. The front of the dust cup unit 20 is configured as an opening and is provided with a cup lid 204 for opening and emptying garbage. The rear of the dust cup unit 20 is provided with a filter component and is connected to the inlet of the motor unit 30.

[0044] The handheld component 1 also includes an air inlet duct 100. The housing unit 10 extends forward and connects to the air inlet duct 100. The front end of the air inlet duct 100 has an air inlet 1008. When using the handheld component 1 alone, the user moves the air inlet duct 100 by holding the handle unit 105, causing the air inlet 1008 to move along the position to be cleaned. Of course, other auxiliary heads can also be connected to the air inlet 1008 to clean different types of surfaces to be cleaned. The rear part of the air inlet duct 100 extends into the housing unit 10 and is in fluid communication with the dust cup unit 20. The air inlet duct 100 has an air outlet (not shown in the figure), and the dust cup unit 20 has an air inlet 203 that is sealed and connected to the air outlet of the air inlet duct 100. Fluid enters from the air inlet 1008 at the front end of the air inlet duct 100, passes through the air outlet and the air inlet 203, and then enters the dust cup unit 20 for dust and air separation. After that, it flows through the filter assembly and then into the motor unit 30, and finally flows out from the motor unit 30. When the handheld component 1 is mounted on the body component, the air inlet duct 100 located at the front of the handheld component 1 connects to the channel on the body component to form a fluid flow path. In one possible embodiment, the dust cup unit 20 is horizontally positioned, i.e., the axis of the dust cup unit 20 is along the X direction, and the dust cup unit 20 is located below the air inlet duct 100. Optionally, the motor unit 30 is horizontally positioned behind the dust cup unit 20.

[0045] The rear of the housing unit 10 is configured as a handle unit 105 for the user to hold. In one possible embodiment, the housing unit 10 extends rearward and downward to form the handle unit 105, which includes a first grip section and a second grip section. The first grip section is located above the motor unit 30, and the second grip section is located behind the motor unit 30, to meet the different gripping needs of the user when using the handheld component 1 alone and when using the whole device vertically by mounting it on the body component.

[0046] In one possible embodiment, the handheld component 1 further includes a power storage unit 40, which is located below the motor unit 30, i.e., at the lower part of the handheld component 1. Since the power storage unit 40 is relatively heavy, placing it at the lower part of the handheld component 1 makes the center of gravity more stable. Of course, in some other embodiments, the power storage unit may be omitted, and an external power source may be used instead.

[0047] The handheld assembly 1 also includes a locking cup unit 50 and a display unit 60. One end of the locking cup unit 50 is exposed outside the handle unit 105, allowing the user to operate the locking cup unit 50 with one hand to release the dust cup unit 20 while holding the assembly. The other end of the locking cup unit 50 is engaged or disengaged from the dust cup unit 20. When the handheld assembly 1 is not subjected to external force, the locking cup unit 50 remains engaged with the dust cup unit 20 to fix the dust cup unit 20 to the housing unit 10. When the user pushes the end exposed outside the handle unit 105, causing the locking cup unit 50 to be subjected to external force, the dust cup unit 20 can be removed from the housing unit 10.

[0048] The display unit 60 is used to display the operating status of the cleaning equipment for user observation. To ensure that the display unit 60 is not obstructed when the user operates the operation keys on the handle unit 105, the display unit 60 is located on the housing unit 10 in front of the handle unit 105. The display panel of the display unit 60 is exposed on the upper surface of the housing unit 10, allowing the user to easily observe the information on the display screen of the display unit 60 when holding it in the first grip section or the second grip section. In this application, the locking cup unit 50 extends forward from behind the display unit 60, bypassing it, to the point where it engages with the dust cup unit 20.

[0049] In one possible embodiment, the dust cup unit 20 and the motor unit 30 are arranged one behind the other, with the axis of the dust cup unit 20 parallel to the axis of the motor unit 30. The locking cup unit 50 extends from above the motor unit 30 to above the front of the dust cup unit 20. Typically, the dust cup unit 20 is connected to the motor unit 30 at its fluid outlet. In this application, the rear end of the dust cup unit 20 is snapped into the front end of the motor unit 30. To better mount the dust cup unit 20 onto the handheld assembly 1, another snapping structure is typically provided near the front end of the dust cup unit 20; this is a common connection method in the art and will not be elaborated further here. Therefore, the other end of the locking cup unit 50 is snapped into the front of the dust cup unit 20, i.e., near the cup cover 204, which means that the locking cup unit 50 must extend at least above the front of the dust cup unit 20.

[0050] In one possible embodiment, the dust cup locking unit 50 includes an unlocking member 503 and a push rod 502. To facilitate convenient disassembly of the dust cup by the user, the unlocking member 503 is at least partially disposed on the handle unit 105. Specifically, one end of the unlocking member 503 forms an operating surface protruding from the handle unit 105 for user operation. Further, as... Figures 3-5 As shown, the display unit 60 is positioned in front of the handle unit 105. The unlocking member 503 extends downward and forward from the rear of the display unit 60 to below it, thus avoiding any spatial conflict between the dust cup unit 50 and the display unit 60. The other end of the unlocking member 503 is connected to a push rod 502. The user pushes the unlocking member 503 to move the push rod 502, thereby unlocking the dust cup unit 20. The rear of the air inlet duct 100 extends into the housing unit 10 and is in fluid communication with the dust cup unit 20. The push rod 502 extends between the air inlet duct 100 and the housing unit 10, extending forward from the rear of the air inlet duct 100 to above the front of the dust cup unit 20.

[0051] To save on the longitudinal dimension of the handheld component 1, the push rod 502 is positioned on the left and / or right side of the air inlet duct 100, making reasonable use of the space between the air inlet duct 100 and the housing unit 10. In this application, the dust cup unit 20 is arranged vertically alongside the air inlet duct 100, and the dust cup unit 20 is a double dust cup, including a cyclone chamber 205 and a dust storage chamber 206 arranged vertically side by side, resulting in a larger longitudinal dimension of the handheld component 1. At the same time, the dimension of the dust cup unit 20 in the Y direction is larger than the dimension of the air inlet duct 100. Therefore, placing part of the locking cup unit 50 on the side of the air inlet duct 100 not only helps to reduce the longitudinal dimension but also contributes to the symmetrical and aesthetically pleasing appearance.

[0052] In one possible embodiment, the push rod 502 includes a left push rod and a right push rod, symmetrically located on the left and right sides of the air inlet duct 100, respectively, to make the thrust transmission more stable and ensure smooth unlocking. Correspondingly, the front part of the unlocking member 503 branches into two ends below the display unit 60 towards the push rod 502, and the two ends are connected to the left push rod and the right push rod, respectively. The projection of the unlocking member 503 in the longitudinal direction is Y-shaped.

[0053] In one possible embodiment, the unlocking member 503 includes a push button 5031 and a connecting part 5032. The push button 5031 extends from a through hole in the handle unit 105 for user operation. The connecting part 5032 is configured to connect the push button 5031 at its rear end and a push rod 502 at its front end. The push button 5031 is located behind the display unit 60, and the connecting part 5032 extends downward and forward from the rear of the display unit 60 to below the display unit 60. In one possible embodiment, the push button 5031 and the connecting part 5032 are integrally formed.

[0054] The dust cup unit 50 also includes a locking member 501. The locking member 501, push rod 502, and unlocking member 503 are connected in sequence. The locking member 501 is connected to the push rod 502. The locking member 501 includes a hook 5011 for engaging with the dust cup unit 20 to fix the dust cup unit 20. In one possible embodiment, the locking member 501 also includes a middle part 5012 and a mounting part 5013. The locking member 501 is arched. The middle part 5012 forms an arch spanning above the air inlet duct 100. Hooks 5011 and mounting parts 5013 are constructed extending downward from both sides of the middle part 5012 to the sides of the air inlet duct 100. The mounting parts 5013 on both sides are arranged facing the push rod 502 and are respectively connected to the front end of the left push rod and the front end of the right push rod, thus ensuring the synchronization and stability of the thrust transmission. The upper surface of the dust cup unit 20 is provided with a locking hook 202, and the hooks 5011 on both sides engage with the locking hook 202 to fix the dust cup unit 20 to the handheld component 1.

[0055] A return spring (not shown) is provided on the side of the locking member 501 away from the push rod 502, so that when the locking member 501 is not subjected to external force, it remains engaged with the locking hook 202 to fix the dust cup unit 20 on the housing unit 10. When the user applies external force (e.g., pushing force) to the unlocking member 503, the push rod 502 drives the locking member 501 to overcome the force of the return spring and realize the disengagement of the locking member 501 from the locking hook 202, thereby allowing the dust cup unit 20 to be removed.

[0056] In one possible embodiment, several support plates 1009 are respectively provided on both sides of the air inlet duct 100 to support the push rods 502 (i.e., the left push rod and the right push rod) so that their movement is more stable and smooth. The support plates 1009 extend outward along the radial direction of the air inlet duct 100 and form L-shaped slots to support the push rods 502.

[0057] Typically, the capacity of the dust cup is considered to reduce the frequency of dust cup cleaning for users. Users want to achieve a large dust storage capacity while keeping the cleaning equipment compact and lightweight. In this application, a dual dust cup design is used for dust storage, which not only meets the need for large capacity but also improves the dust-air separation effect.

[0058] The handheld component 1 of this application is further provided with a first coupler 2, and the body component is provided with a second coupler that can be plugged and detached from the first coupler 2. When the handheld component 1 and the body component are assembled, the first coupler 2 and the second coupler are coupled together to form a conductive circuit. Figure 9As shown, to further save space and maintain the aesthetics of the handheld component 1, a mounting cavity 1004 with an opening on one side is provided protruding downwards from the bottom of the air inlet duct 100, facing forward. The mounting cavity 1004 is used to mount the first coupler 2. Correspondingly, a notch 201 is provided on the dust cup unit 20 to fit the mounting cavity 1004, complementing each other spatially. The mounting cavity 1004 is formed on the outer surface of the air inlet duct 100 to reduce the impact on the fluid flow within the air inlet duct 100, thus not affecting the fluid flow path. In addition, the notch 201 on the dust cup unit 20 is located at the upper part of the dust cup unit 20 and close to the cup cover 204, that is, close to the bottom of the dust cup unit 20. Therefore, the notch 201 has little impact on the cyclone effect and storage capacity of the inner cavity of the cup. When the dust cup unit 20 is mounted on the handheld component 1, the two fit together, resulting in a simple and aesthetically pleasing appearance. In one possible embodiment, the notch 201 is located in front of the locking hook 202. In another possible embodiment, the notch 201 is positioned facing forward and upward to better accommodate the mounting cavity 1004.

[0059] The dust cup unit 20 also includes a cup lid lock 207. A pivot and a torsion spring (not shown) for rotating the cup lid 204 are provided at the notch 201. Along the longitudinal direction, the cup lid lock 207 is provided on the opposite side of the notch 201. When the cup lid lock 207 is released by external force, the cup lid 204 flips upward, and the garbage is poured out under the action of gravity, which will not pour the garbage onto the hand and cause hand contamination. Compared with the cup lid flipping downward, there is no garbage residue on the inner surface of the cup lid 204 of this application, and the garbage will not be scattered on the handheld component 1 again when the cup lid 204 is closed, causing secondary contamination of the handheld component 1.

[0060] The housing unit 10 also includes a duct cover 101. The duct cover 101 has a certain thickness in the X direction to accommodate part of the first coupler 2. Specifically, the duct cover 101 forms a recessed portion from its surface inward along the X direction, and a through hole 102 is provided at the bottom of the recessed portion to expose the first coupler 2, but the first coupler 2 does not extend beyond the surface of the duct cover 101 to protect the first coupler 2. The duct cover 101 has another through hole for the air inlet duct 100 to pass through. The duct cover 101 covers the opening of the mounting cavity 1004. After the duct cover 101 covers the mounting cavity 104, the fluid passage of the air inlet duct 100 and the mounting cavity 1004 are separated, so it will not affect the fluid in the fluid passage. The plug-in terminal of the first coupler 2 inside the mounting cavity 1004 extends out from the through hole 102, while the air duct cover 101 seals the end of the gap between the air inlet duct 100 and the housing unit 10.

[0061] An adapter plate 1005 is also provided inside the mounting cavity 1004. The first coupler 2 is fixed on the side of the adapter plate 1005 facing the air duct cover 101. Part of the first coupler 2 and the adapter plate 1005 are disposed within the mounting cavity 1004, and the adapter plate 1005 can move back and forth along the axis of the air inlet duct 100. The adapter plate 1005 with the first coupler 2 inside the handheld assembly 1 is designed to float, so that the first coupler 2 can always maintain close contact with the second coupler. The floating design provides a certain tolerance to improve the stability and reliability of the docking between the first coupler 2 and the second coupler, preventing the coupler from loosening and affecting the function when the user holds the handheld assembly 1 and moves the whole machine back and forth. When the second coupler of the body assembly moves forward, the adapter plate 1005 drives the first coupler 2 to move forward synchronously, maintaining a tight fit between the first coupler 2 and the second coupler, preventing functional loss due to poor contact, and solving the problem of poor contact between the handheld assembly and the body assembly during user operation.

[0062] like Figure 9 As shown, the inner wall of the mounting cavity 1004 is provided with a protruding rib 1001. The protruding rib 1001 is used to limit the side of the adapter plate 1005 away from the first coupler 2. There is a gap between the side of the adapter plate 1005 near the first coupler 2 and the air duct cover plate 101. One side of the adapter plate 1005 is limited by the air duct cover plate 101, and the other side is limited by the protruding rib 1001. The air duct cover plate 101 and the protruding rib 1001 limit the movement distance of the adapter plate 1005, ensuring that the adapter plate 1005 can move a certain distance in the axial direction of the air duct 100. When the second coupler of the body assembly moves forward, the adapter plate 1005 drives the first coupler 2 to move forward synchronously, keeping the first coupler 2 and the second coupler tightly fitted and preventing functional loss due to poor contact.

[0063] like Figure 12 and Figure 13 As shown, the adapter plate 1005 has a raised rib 1006 on one side where the first coupler 2 is located. The raised ribs 1006 are arranged in pairs and are configured as mirror hooks, clamping the first coupler 2 between the raised ribs 1006, so that the first coupler 2 is firmly fixed on the adapter plate 1005. The raised ribs 1006 are closer to the air duct cover plate 101 than the adapter plate 1005. Therefore, in order to meet the back-and-forth movement function of the adapter plate 1005, there is also a gap between the raised ribs 1006 and the air duct cover plate 101.

[0064] like Figure 10As shown, in order to further increase the forward and backward movement distance of the adapter plate 1005, in this embodiment, a first relief groove 103 is formed by recessing the air duct cover plate 101 inward at the position corresponding to the protruding rib 1006. When the first coupler 2 moves forward through the adapter plate 1005, the first coupler 2 continues to extend out from the through hole 102, and the protruding rib 1006 moves toward the first relief groove 103 to further increase the gap between the protruding rib 1006 and the air duct cover plate 101.

[0065] The first coupler 2 is located at least partially within the through hole 102. When the adapter plate 1005 drives the first coupler 2 to move back and forth, the first coupler 2 can move back and forth synchronously within the through hole 102.

[0066] like Figure 9 and Figure 11 As shown, the inner wall of the mounting cavity 1004 is provided with a pair of studs 1002 for mounting and positioning the air duct cover 101. The two ends of the adapter plate 1005 extend outward to form hanging arms 111, which are mounted on the corresponding studs 1002. The studs 1002 provide upward support for the adapter plate 1005. Compared with the conventional technology where the adapter plate 1005 is fastened to the studs 1002 through the mating holes, in this application, the studs 1002 only provide support for the hanging arms 111 of the adapter plate 1005 and do not fix the adapter plate 1005, allowing the adapter plate 1005 to move in the radial direction.

[0067] like Figure 12 As shown, in order to reduce frictional loss between the hanging arm 111 and the stud 1002, an arc-shaped surface 113 is formed at the end of the hanging arm 111 facing the stud 1002, so that the adapter plate 1005 moves more smoothly in the radial plane.

[0068] like Figure 11 As shown, in order to enable the adapter plate 1005 to move in the left and right directions, there is a gap between the side wall 114 of the adapter plate 1005 and the corresponding stud 1002.

[0069] like Figure 11 As shown, in order to enable the adapter plate 1005 to move in the vertical direction, there is a gap between the upper part of the adapter plate 1005 and the air inlet duct 100, and a gap between the lower part of the adapter plate 1005 and the inner bottom wall 1003 of the mounting cavity 1004.

[0070] like Figure 4 As shown, further, the upper part of the adapter plate 1005 is recessed inward to form a second clearance groove 112, which makes the gap between the upper part of the adapter plate 1005 and the air inlet duct 100 larger, thereby increasing the moving distance of the adapter plate 1005.

[0071] Therefore, the adapter plate 1005 has gaps in the axial direction, left and right direction and up and down direction of the air inlet duct 100, so that the adapter plate 1005 can float with the first coupler 2, which solves the problem of poor contact between the first coupler 2 on the handheld component 1 and the second coupler on the body component.

[0072] The beneficial effects of this utility model are:

[0073] 1. The adapter plate 1005 with the first coupler 2 inside the handheld assembly 1 is designed to float. The adapter plate 1005 is located inside the mounting cavity 1004 and can move back and forth along the axis of the air inlet duct 100. When the second coupler of the main body assembly moves forward, the adapter plate 1005 drives the first coupler 2 to move forward synchronously, maintaining a tight fit between the first coupler 2 and the second coupler and preventing functional loss due to poor contact. The floating design provides a certain tolerance to improve the stability and reliability of the docking of the first coupler 2 and the second coupler, preventing the coupler from loosening and affecting the function when the user holds the handheld assembly 1 and moves the whole machine back and forth.

[0074] 2. In this utility model, the adapter plate 1005 is not fastened to the two studs 1002 by closed holes on both sides. Instead, two hanging arms 111 are designed to rest on the studs 1002. At the same time, a small gap is left between the adapter plate 1005 and the outer wall of the air duct 100 and the inner bottom wall 1003 of the mounting cavity 1004. Therefore, the adapter plate 1005 can have a certain floating space in the left and right directions and the up and down directions in the mounting cavity 1004. When the first coupler 2 and the second coupler are slightly misaligned, they can float and align themselves.

[0075] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, 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.
