[0038] like Figures 1-13 As 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.

[0039] 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.

[0040] The handheld assembly 1 comprises 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 in front and back of each other and are both arranged on the housing unit 10, the front part of the dust cup unit 20 is configured to be open and is provided with a cup cover 204 for opening and dumping garbage, and the rear part of the dust cup unit 20 is provided with a filter assembly and is connected with an inlet of the motor unit 30.

[0041] The handheld assembly 1 further comprises an air inlet pipe 100, the housing unit 10 extends forward to connect the air inlet pipe 100, and the air inlet pipe 100 is provided with an air inlet 1008 at the front end, when the handheld assembly 1 is used alone, a user moves the air inlet pipe 100 by holding the handle unit 105 to move the air inlet 1008 along the position to be cleaned. Of course, other auxiliary heads can also be connected at the air inlet 1008 to clean different types of surfaces to be cleaned. The rear part of the air inlet pipe 100 extends into the housing unit 10 and is in fluid communication with the dust cup unit 20. The air inlet pipe 100 is provided with an air outlet (not shown), and the dust cup unit 20 is provided with an air inlet 203 which is in sealing butt joint with the air outlet of the air inlet pipe 100, fluid enters from the air inlet 1008 at the front end of the air inlet pipe 100, passes through the air outlet and the air inlet 203 to arrive at the inside of the dust cup unit 20 for dust-gas separation, then flows through the filter assembly to enter the motor unit 30, and finally flows out of the motor unit 30. When the handheld assembly 1 is installed on the main body assembly, the air inlet pipe 100 located at the front part of the handheld assembly 1 is connected with a channel on the main body assembly to form a fluid flow path. In a possible embodiment, the dust cup unit 20 is transversely arranged, that is, 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 pipe 100. Optionally, the motor unit 30 is transversely arranged behind the dust cup unit 20.

[0042] The rear part of the housing unit 10 is configured as the handle unit 105 for a user to hold. In a possible embodiment, the housing unit 10 extends rearward and downward to form the handle unit 105, and the handle unit 105 comprises a first holding section and a second holding section, the first holding section is located above the motor unit 30, and the second holding section is located behind the motor unit 30, so as to meet different holding requirements of a user when the handheld assembly 1 is used alone and when the handheld assembly 1 is installed on the main body assembly for upright use of the whole machine.

[0043] In a possible embodiment, the handheld assembly 1 further comprises a power storage unit 40, and the power storage unit 40 is arranged below the motor unit 30, that is, at the lower part of the handheld assembly 1. Since the power storage unit 40 is heavy, arranging it at the lower part of the handheld assembly 1 can make the center of gravity more stable. Of course, in some other embodiments, the power storage unit can also not be arranged, and a plug-in external power supply mode can be used for power supply.

[0044] The handheld assembly 1 further comprises a lock cup unit 50 and a display unit 60. One end of the lock cup unit 50 is exposed to the handle unit 105, so that the user can operate the lock cup unit 50 with one hand to release the dust cup unit 20 while holding the handheld assembly 1. The other end of the lock cup unit 50 is connected to or detached from the dust cup unit 20. When the handheld assembly 1 is not subjected to external force, the lock cup unit 50 is kept connected to the dust cup unit 20 to fix the dust cup unit 20 to the housing unit 10. When the user pushes the end exposed to the handle unit 105 to subject the lock cup unit 50 to external force, the dust cup unit 20 can be detached from the housing unit 10.

[0045] The display unit 60 is used to display the running state of the cleaning device for the user to observe. In order to ensure that the user does not block the display unit 60 when operating the operation keys on the handle unit 105, the display unit 60 is arranged on the housing unit 10 in front of the handle unit 105, and the display panel of the display unit 60 is exposed to the upper surface of the housing unit 10. When the user holds the first holding section and the second holding section, the user can conveniently observe the information on the display screen of the display unit 60. In the present application, the lock cup unit 50 extends forward from behind the display unit 60 to the position where it is connected to the dust cup unit 20.

[0046] In a possible embodiment, the dust cup unit 20 and the motor unit 30 are arranged in front of and behind each other, and the axis of the dust cup unit 20 is parallel to the axis of the motor unit 30. The lock cup unit 50 extends from above the motor unit 30 to above the front part of the dust cup unit 20. Generally, the dust cup unit 20 is connected to the motor unit 30 at the fluid outlet thereof. In the present application, the rear end of the dust cup unit 20 is connected to the front end of the motor unit 30. In order to better fix the dust cup unit 20 to the handheld assembly 1, another connection structure is generally arranged near the front end of the dust cup unit 20, which is a common connection method in the art and will not be described herein. Therefore, the position where the other end of the lock cup unit 50 is connected to the dust cup unit 20 is located in the front part of the dust cup unit 20, i.e., near the cup cover 204, which makes the lock cup unit 50 at least extend above the front part of the dust cup unit 20.

[0047] In a possible embodiment, the lock cup unit 50 comprises an unlocking member 503 and a push rod 502. In order to enable the user to conveniently detach the dust cup, the unlocking member 503 is at least partially arranged on the handle unit 105. Specifically, one end of the unlocking member 503 is formed with an operation surface protruding from the operation surface of the handle unit 105 for the user to operate. Further, as shown in FIG. 1, the push rod 502 is arranged on the handle unit 105 and is connected to the unlocking member 503. Figures 3-5As shown, the display unit 60 is arranged in front of the handle unit 105, and the unlocking member 503 extends downwardly from the rear of the display unit 60 and forwardly to the lower side of the display unit 60, so that the space arrangement of the lock cup unit 50 and the display unit 60 does not cause conflict. The other end of the unlocking member 503 is connected to the push rod 502, and the user pushes the unlocking member 503 to move the push rod 502 to achieve unlocking of the dust cup unit 20. The rear of the air inlet duct 100 extends into the casing unit 10 and is in fluid communication with the dust cup unit 20, and the push rod 502 extends between the air inlet duct 100 and the casing unit 10, and the push rod 502 extends forwardly from the rear of the air inlet duct 100 to the upper side of the front of the dust cup unit 20.

[0048] In order to save the longitudinal size of the handheld assembly 1, the push rod 502 is arranged on the left side and / or the right side of the air inlet duct 100, and the space between the air inlet duct 100 and the casing unit 10 is reasonably utilized. In this application, the dust cup unit 20 is arranged side by side above and below the air inlet duct 100, and the dust cup unit 20 is a double dust cup including a cyclone cavity 205 and an ash storage cavity 206 arranged side by side above and below, so that the size of the handheld assembly 1 in the longitudinal direction is relatively large; at the same time, the size of the dust cup unit 20 in the Y direction is larger than the size of the air inlet duct 100, so that part of the lock cup unit 50 is arranged beside the air inlet duct 100, which is not only beneficial to reducing the longitudinal size, but also beneficial to the uniformity and beauty of the appearance.

[0049] In a possible embodiment, the push rod 502 includes a left push rod and a right push rod, which are symmetrically arranged on the left side and the right side of the air inlet duct 100, respectively, so that the transmission of the pushing force is more stable and ensures smooth unlocking. Correspondingly, the front of the unlocking member 503 bifurcates into two end portions below the display unit 60 and towards the push rod 502, and the two end portions are connected to the left push rod and the right push rod, respectively, and the projection of the unlocking member 503 in the longitudinal direction is Y-shaped.

[0050] In a possible embodiment, the unlocking member 503 includes a push button portion 5031 and a connecting portion 5032, the push button portion 5031 extends out of a through hole on the handle unit 105 for user operation, and the connecting portion 5032 is configured in a suitable shape for connecting the push button portion 5031 at the rear end thereof and connecting the push rod 502 at the front end thereof. The push button portion 5031 is located behind the display unit 60, and the connecting portion 5032 extends downwardly from the rear of the display unit 60 and forwardly to the lower side of the display unit 60. In a possible embodiment, the push button portion 5031 and the connecting portion 5032 are integrally formed.

[0051] The locking cup unit 50 further comprises a locking piece 501, the locking piece 501, the push rod 502 and the unlocking piece 503 are sequentially connected, the locking piece 501 is connected with the push rod 502, the locking piece 501 comprises a clamping hook 5011, which is used for clamping connection with the dust cup unit 20 to fix the dust cup unit 20. In a possible embodiment, the locking piece 501 further comprises an intermediate portion 5012 and a mounting portion 5013, the locking piece 501 is in an arch shape, the intermediate portion 5012 forms an arch top spanning above the air inlet duct 100, the clamping hook 5011 and the mounting portion 5013 are configured on both sides of the intermediate portion 5012 and downwardly extend to the side edges of the air inlet duct 100, the mounting portions 5013 on both sides are arranged towards the push rod 502 and are respectively connected with the front ends of the left push rod and the right push rod, in this way, the synchronization and stability of the transmission of the pushing force are ensured. The upper surface of the dust cup unit 20 is provided with a locking hook 202, the clamping hooks 5011 on both sides are clamped with the locking hook 202 to fix the dust cup unit 20 on the handheld assembly 1.

[0052] The side of the locking piece 501 away from the push rod 502 is provided with a reset spring (not shown), so that when the locking piece 501 is not subjected to external force, the clamping with the locking hook 202 is maintained to fix the dust cup unit 20 on the casing unit 10, when the user applies external force (for example, pushing force) to the unlocking piece 503, the locking piece 501 is driven by the push rod 502 to overcome the force of the reset spring to realize the disengagement of the locking piece 501 from the locking hook 202, and then the dust cup unit 20 can be taken.

[0053] In a possible embodiment, a plurality of support plates 1009 are arranged on both sides of the air inlet duct 100 respectively, which are used for supporting the push rod 502 (i.e., the left push rod and the right push rod) to make the movement more stable and smooth. The support plates 1009 extend outwardly along the radial direction of the air inlet duct 100 and form L-shaped notches to support the push rod 502.

[0054] Generally, in order to reduce the frequency of cleaning the dust cup of the user, the capacity of the dust cup is considered, and the user will hope to balance the small and light cleaning equipment and obtain the largest capacity of dust storage as much as possible. In the present application, double dust cups are arranged for dust storage, which not only meets the demand of large capacity, but also improves the dust and gas separation effect.

[0055] The handheld assembly 1 further comprises a first coupler 2, and the machine body assembly is provided with a second coupler which can be plug-connected with the first coupler 2. When the handheld assembly 1 and the machine body assembly are assembled, the first coupler 2 and the second coupler are coupled with each other to form a circuit conduction. Figure 9As shown, in order to further save the space of the handheld assembly 1 and maintain its aesthetics, a side-opened mounting cavity 1004 is provided at the bottom of the air inlet pipe 100 and protrudes downward, the opening faces forward, the mounting cavity 1004 is used for mounting the first coupler 2, and correspondingly, the gap 201 opened on the dust cup unit 20 is complementary in space to the mounting cavity 1004. The mounting cavity 1004 is formed on the outer surface of the air inlet pipe 100 to reduce the influence on the fluid flow in the air inlet pipe 100, thus not affecting the fluid flow path, in addition, the gap 201 on the dust cup unit 20 is located at the upper part of the dust cup unit 20 and is close to the cup cover 204, that is, close to the bottom of the dust cup unit 20. Therefore, the opening of the gap 201 has little effect on the cyclone effect and storage capacity of the inner cavity of the cup body. When the dust cup unit 20 is mounted on the handheld assembly 1, the two are adapted, and the appearance is simple and beautiful. In one possible embodiment, the gap 201 is located in front of the lock hook 202. In another possible embodiment, the gap 201 is provided towards the front and upward to better accommodate the mounting cavity 1004.

[0056] The dust cup unit 20 further comprises a cup cover lock 207, a rotating shaft and a torsion spring (not shown) are provided at the gap 201 for the rotation of the cup cover 204, along the longitudinal direction, the opposite side of the gap 201 is provided with the cup cover lock 207, when the cup cover lock 207 is released by external force, the cup cover 204 is flipped upward, the garbage is poured out under the action of gravity, and the hand is not polluted by the garbage, compared with the opening mode of the cup cover flipped downward, the inner surface of the cup cover 204 of the present application has no garbage residue, and the garbage will not be scattered on the handheld assembly 1 again due to the closing of the cup cover 204, causing secondary pollution of the handheld assembly 1.

[0057] The housing unit 10 further comprises an air duct cover plate 101, the air duct cover plate 101 has a certain thickness in the X direction to accommodate part of the first coupler 2, specifically, the air duct cover plate 101 forms a recess inward from its surface along the X direction, and the bottom of the recess is provided with a through hole 102 to expose the first coupler 2, but the first coupler 2 does not exceed the surface of the air duct cover plate 101 to protect the first coupler 2. The air duct cover plate 101 is provided with another through hole for the air inlet pipe 100 to pass through, and the air duct cover plate 101 is provided on the opening of the mounting cavity 1004, when the air duct cover plate 101 is provided on the mounting cavity 1004, the fluid passage of the air inlet pipe 100 and the mounting cavity 1004 are separated, thus not affecting the fluid in the fluid passage. The plug-in terminal of the first coupler 2 in the mounting cavity 1004 extends from the through hole 102, at the same time, the air duct cover plate 101 closes the gap between the air inlet pipe 100 and the housing unit 10 at the end.

[0058] The adapter plate 1005 is arranged in the mounting cavity 1004, the first coupler 2 is fixed on the side of the adapter plate 1005 facing the air duct cover plate 101, and part of the first coupler 2 and the adapter plate 1005 are arranged in the mounting cavity 1004 and the adapter plate 1005 can move forward and backward along the axis direction of the air inlet pipe 100. The adapter plate 1005 with the first coupler 2 in the handheld assembly 1 is designed to be floating, so that the first coupler 2 can always be in close contact with the second coupler. 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, and prevents the user from holding the handheld assembly 1 to drive the whole machine to work forward and backward, causing the coupler to loosen and affecting the function. When the second coupler of the machine body assembly moves forward, the adapter plate 1005 drives the first coupler 2 to move forward synchronously, keeps the first coupler 2 and the second coupler in close cooperation, and prevents the loss of function caused by poor contact, solving the problem of poor contact between the handheld assembly and the machine body assembly during use.

[0059] As shown in Figure 9 , the inner wall of the mounting cavity 1004 is provided with a protruding rib 1001, which 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 close to 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 movement distance of the adapter plate 1005 is limited by the air duct cover plate 101 and the protruding rib 1001, which ensures that the adapter plate 1005 can move a certain distance in the axis direction of the air pipe 100. When the second coupler of the machine body assembly moves forward, the adapter plate 1005 drives the first coupler 2 to move forward synchronously, keeps the first coupler 2 and the second coupler in close cooperation, and prevents the loss of function caused by poor contact.

[0060] As shown in Figure 12 and Figure 13 , the side of the adapter plate 1005 where the first coupler 2 is arranged is also provided with a protruding rib 1006, which is arranged in pairs and configured as a mirror image hook to clamp the first coupler 2 between the protruding ribs 1006, so that the first coupler 2 is firmly fixed on the adapter plate 1005. The protruding rib 1006 is closer to the air duct cover plate 101 than the adapter plate 1005, so in order to meet the forward and backward movement function of the adapter plate 1005, there is also a gap between the protruding rib 1006 and the air duct cover plate 101.

[0061] As shown in Figure 10As shown, in order to further increase the front and back moving distance of the adapter plate 1005, in this embodiment, a first avoiding slot 103 is formed by inwardly recessing the air duct cover plate 101 at the position corresponding to the protruding rib 1006. When the first coupler 2 continues to extend out of the through hole 102 and the protruding rib 1006 moves towards the first avoiding slot 103 when the first coupler 2 moves forward with the adapter plate 1005, the gap between the protruding rib 1006 and the air duct cover plate 101 is further increased.

[0062] The first coupler 2 is at least partially located in the through hole 102, and when the adapter plate 1005 moves forward and backward with the first coupler 2, the first coupler 2 can move forward and backward in the through hole 102 synchronously.

[0063] As shown in Figure 9 and Figure 11 As shown, the inner wall of the mounting cavity 1004 is provided with a pair of screw columns 1002 for mounting and positioning the air duct cover plate 101, and the two ends of the adapter plate 1005 extend outwardly to form a hanging arm 111 which is loaded on the corresponding screw column 1002. The screw column 1002 plays a role of upward supporting for the adapter plate 1005. Compared with the conventional technology in which a matching hole is formed on the adapter plate 1005 and the adapter plate 1005 is tightly sleeved on the screw column 1002 through the matching hole, in this application, the screw column 1002 only plays a supporting role for the hanging arm 111 of the adapter plate 1005 and does not fix the adapter plate 1005, so that the adapter plate 1005 can move in the radial direction.

[0064] As shown in Figure 12 In order to reduce the friction loss between the hanging arm 111 and the screw column 1002, an arc surface 113 is formed at the end of the hanging arm 111 towards the screw column 1002, so that the adapter plate 1005 moves more smoothly in the radial plane.

[0065] As shown in Figure 11 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 screw column 1002.

[0066] As shown in Figure 11 In order to enable the adapter plate 1005 to move in the up and down directions, there is a gap between the upper part of the adapter plate 1005 and the air inlet duct 100, and there is a gap between the lower part of the adapter plate 1005 and the inner bottom wall 1003 of the mounting cavity 1004.

[0067] As shown in Figure 4 Further, the upper part of the adapter plate 1005 is recessed inwardly to form a second avoiding slot 112, so that the gap between the upper part of the adapter plate 1005 and the air inlet duct 100 is larger, and the moving distance of the adapter plate 1005 is improved.

[0068] Therefore, the adapter plate 1005 is provided with gaps in the axial direction, the left-right direction and the up-down direction of the air inlet pipe 100, so that the adapter plate 1005 is floating when the first coupler 2 is mounted thereon, and the problem of poor contact between the first coupler 2 on the handheld assembly 1 and the second coupler on the fuselage assembly is solved.

[0069] The utility model discloses the beneficial effects of:

[0070] The rear part of the air inlet pipe 100 extends into the shell unit 10 and is in fluid communication with the dust cup unit 20, the dust cup unit 20 is horizontally placed and located below the air inlet pipe 100, the bottom of the air inlet pipe 100 protrudes downward and is provided with a mounting cavity 1004 with one side opening, the first coupler 2 is installed in the mounting cavity 1004, since the mounting cavity 1004 is opened in the bottom of the air inlet pipe 100 and protrudes downward, therefore, the installation of the mounting cavity 1004 has no effect on the air inlet pipe 100. Further, the protruding mounting cavity 1004 is matched with the notch 201 opened on the dust cup unit 20, which makes the dust cup unit 20 simple and beautiful in appearance after being installed on the handheld assembly 1.

[0071] The notch 201 is located near the cup cover 204 of the dust cup unit 20, so it has little effect on the internal space of the dust cup unit 20, and further will not have a negative impact on the cyclone effect of the dust cup unit 20.

[0072] The above-described embodiments only express several implementation manners of the utility model, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the utility model patent. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the utility model, some modifications and improvements can be made, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
