DETAILED DESCRIPTION

[0029] To describe the technical content, structural features, achieved purpose and effect of the application in detail, the technical scheme in the embodiment of the application will be described below in conjunction with the drawings in the embodiment of the application. Obviously, the described embodiment is only a part of the embodiment of the application, rather than all the embodiments. In the following description, for the purpose of explanation, many specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the application. However, various exemplary embodiments may also be implemented without these specific details or in the case of one or more equivalent arrangements. In addition, various exemplary embodiments may be different, but not necessarily exclusive. For example, without departing from the concept of the present application, the specific shape, structure and characteristics of the exemplary embodiment may be used or implemented in another exemplary embodiment.

[0030] The terms “upper” and “lower” in this application refer to the attached Figure 1 The above and below shown in the figure; the "front" and "rear" mentioned in this application are as shown in the figure. Figure 1 The front and rear shown in the figure; the "left" and "right" in this application refer to the attached Figure 1 Before and after shown.

[0031] In the present application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0032] like Figure 1 As shown, a cleaning device 100 is provided, the cleaning device 100 comprises a cleaning head 10 and a handle body portion 20, wherein the handle body portion 20 is detachably connected to the cleaning head 10. Figure 2 As shown, the handle body part 20 can be placed separately on a plane 500 after being removed from the cleaning device 100. The handle body part 20 includes a shell 201, a handle rod assembly 202 installed on the upper part of the shell 201, and a portable vacuum main unit 30 that can be releasably held on the shell 201.

[0033] See also Figure 3 The housing 201 is generally annular and has a cavity 203 extending from front to back in the middle thereof. The portable vacuum cleaner main unit 30 can be detachably held in the cavity 203. The portable vacuum cleaner main unit 30 has a first end 301 and a second end 302 that are far from each other and is in the shape of an elongated cylinder as a whole. The portable vacuum cleaner main unit 30 is configured to meet the needs of a user to carry it with one hand and includes a suction nozzle 32 having a dirty air inlet 31 and a dust cup 33 for receiving dust and debris. In this example, the dust cup 33 has a releasable bottom cover 331; the suction nozzle 32 and the bottom cover 331 are integral components and are hinged to the dust cup 33.

[0034] The suction nozzle 32 is arranged at the first end 301. A lower holding seat 204 is fixedly provided at the lower part of the cavity 203. The lower holding seat 204 is connected to the first suction nozzle 1021 (see Figure 7 ) is fluidically connected and is configured to fit the first end 301. An upper retaining seat 205 that can slide up and down is provided at the upper portion of the cavity 203. The upper retaining seat 205 is configured to fit the second end 302.

[0035] like Figure 4 As shown, the portable vacuum cleaner host 30 also includes a vacuum motor 34 for generating suction force and sucking air into the dirty air inlet 31, and a rechargeable battery 35. The housing 201 is provided with a lower limit member 206 and an upper limit member 207 that can limit the upper retaining seat 205 to a first fixed position and a second fixed position, respectively. The lower limit member 206 is supported on the inner wall surface of the housing 201 by a spring 208, and the upper limit member 207 is supported on the inner wall surface of the housing 201 by a spring 209. Figure 5As shown, the upper retaining seat 205 is limited to the first fixed position, at which time the lower limit member 206 engages with the recess 2051 on the outer wall of the upper retaining seat 205, and the upper retaining seat 205 is prevented from moving up and down. In order to facilitate the upper and lower movement of the upper retaining seat 205, a handle 2052 is provided on the top of the upper retaining seat 205. A slide rail 210 extending up and down is provided on the side of the housing 201 facing the cavity 203, and the upper retaining seat 205 can slide along the slide rail 210; the upper limit member 207 and the lower limit member 206 will be arranged near the upper and lower ends of the slide rail 210. Similarly, if the upper retaining seat 205 is limited to the second fixed position, the upper limit member 206 will engage with the recess 2051 on the outer wall of the upper retaining seat 205.

[0036] When the upper retaining seat 205 is in the first fixed position, the portable vacuum cleaner host 30 can be locked in the annular cavity 203 of the housing 201. At this time, the first end 301 of the portable vacuum cleaner host 30 is engaged with the lower retaining seat 204, and the second end 302 is engaged with the upper retaining seat 205. Since the upper retaining seat 205 is fixed by the lower limit member 206 at this time, the portable vacuum cleaner host 30 will be locked in the annular space 203. When the user needs to take the portable vacuum cleaner host 30 out of the annular space 203, the upper retaining seat 205 is pulled upward and the lower limit member 206 is pressed to overcome the force of the spring 208. The lower limit member 206 will deviate to one side under the pressing force, and the upper retaining seat 205 is released, and can be further moved upward, so that the portable vacuum cleaner host 30 can be taken out of the annular space 203; at this time, the upper retaining seat 205 can continue to move upward to the second fixed position and be fixed by the upper limit member 207 to wait for the next movement.

[0037] In other embodiments, the limiting between the upper retaining seat and the shell can also be achieved by a magnetic component or other locking component with a release button.

[0038] Combination Figures 6 to 10 The cleaning head 10 includes a base 101 and a suction nozzle assembly 102, wherein the base 101 is located at the rear side of the cleaning head 10, the suction nozzle assembly 102 is located at the front side of the cleaning head 10, and the base 101 and the suction nozzle assembly 102 are rotatably connected.

[0039] In some embodiments, the base 101 is configured to support a replaceable cleaning cloth. Exemplarily, there is an adhesive layer at the bottom of the base 101, and the cleaning cloth can be adhered to the adhesive layer. When the cleaning cloth needs to be replaced, the user tears off the cleaning cloth. Exemplarily, there can also be a fixing portion 1011 for four replaceable cleaning cloths on the top of the base 101. After the replaceable cleaning cloth is placed under the base 101, it is folded upward and covers the front end wall and the rear end wall of the base 101, and is inserted into the fixing portion 1011 to fix the replaceable cleaning cloth. Of course, other methods can also be used to fix the cleaning cloth, and this embodiment is not limited to this.

[0040] The nozzle assembly 102 includes a nozzle 1021 and a mounting arm 1022. The nozzle 1021 and the mounting arm 1022 are fixedly connected. The mounting arm 1022 is rotatably connected to the base 101. The movement of the mounting arm 1022 drives the movement of the nozzle 1021. Figure 1 , Figure to Figure 4 , the nozzle 1021 extends in the left-right direction, and the mounting arm 1022 extends in the front-back direction. In some embodiments, the number of the mounting arm 1022 is at least one, and the mounting arm 1022 is connected to the middle position of the nozzle 1021; in some embodiments, the number of the mounting arm 1022 is two, such as Figure 6 , 7 As shown, the two mounting arms 1022 are respectively located on both sides of the middle position of the suction nozzle 1021, and the two mounting arms 1022 are connected by a connecting piece 1023; in some embodiments, the number of mounting arms 1022 can be 3 or more, and their relative positions with the suction nozzle 1021 can refer to Figure 6 and Figure 7 The arrangement is made and no further elaboration is given here.

[0041] The suction nozzle 1021 has a dirty air inlet, and the base 101 has a pipe (not shown in the figure), one end of which is connected to the suction nozzle 1021, and the other end is connected to the inlet of the dust cup, thereby forming an air circulation passage through the suction nozzle 1021, the dust cup, the suction motor and the air outlet.

[0042] The nozzle assembly 102 can rotate relative to the base 101 between a first position and a second position. Figure 7 As shown, the nozzle assembly 102 is located in the first position, the nozzle assembly 102 is close to the surface to be cleaned, and the nozzle assembly 102 is located at the front side of the base 101, as shown in FIG. Figure 8 As shown, the suction nozzle assembly 102 is located in the second position, and the suction nozzle assembly 102 leaves the floor to be cleaned. At this time, the suction nozzle assembly 102 is located on the upper side of the base 101.

[0043] The cleaning head 10 further includes a locking member 103, which is mounted on the base 101. The locking member 103 can lock the mounting arm 1022 so as to keep the suction nozzle assembly 102 in the first position, and can release the mounting arm 1022 in the first position under the action of an external force so as to move the suction nozzle assembly 102 to the second position. In some embodiments, the number of the locking member 103 is at least one, and one mounting arm 1022 can correspond to one locking member 103, or can correspond to multiple locking hooks 103.

[0044] The cleaning head 10 further includes an actuating member 104, which is mounted on the nozzle assembly 102. In the forward direction, the actuating member 104 relatively protrudes from the nozzle assembly 102. In some embodiments, the actuating member 104 is combined with the nozzle assembly 102 to form a plurality of actuating members. Figure 6 , Figure 7 The number of mounting arms 1022 is 2, the actuating member 104 includes a first member 1041 extending in the left-right direction and a protrusion 1042 located on the front wall surface of the first member 1041, the front wall surface of the first member 1041 and the front wall surface of the suction nozzle 1021 are substantially flush in the up-down direction, and in the forward direction, the protrusion 1042 protrudes relative to the front wall surface of the suction nozzle 1021, and further, the protrusion 1042 is made of a flexible material and is a flexible protrusion.

[0045] like Fig.11 As shown, the actuating member 104 has a first actuating position in the front-to-rear direction, such as Fig.12As shown, the actuating member has a second actuating position in the front-to-rear direction, wherein the first actuating position is before the second actuating position, and the movement of the actuating member 104 between the first actuating position and the second actuating position is a translational movement, wherein the first actuating position is the position of the actuating member 104 when the cleaning device 100 is in normal use, and the second actuating position is the position where the locking member 103 unlocks the mounting arm 1022. In the present application, when the cleaning device 100 is in normal use, the nozzle assembly 102 is located in the first position, and the actuating member 104 is located in the first actuating position. When there is an obstacle in the forward direction of the cleaning head 10, the actuating member 104 can collide with the obstacle before the nozzle assembly 102. Specifically, the protrusion 1042 on the actuating member 104 collides with the obstacle before the nozzle 1021, and after the actuating member 104 collides with the obstacle, the actuating member 104 moves from the first actuating position to the second actuating position, and at the same time causes the locking member 103 to release the mounting arm 1022, so that the mounting arm 1022 drives the nozzle 1021 to move from the first position to the second position. When the nozzle assembly 102 is in the second position, the nozzle assembly 102 is lifted and is higher than the base 101 as a whole. The user can push the base 101 to continue to move forward, so that the cleaning sheet can clean to the position when the nozzle assembly 102 is not lifted, thereby achieving the cleaning of corners such as wall corners. In order to prevent the nozzle assembly 102 from touching obstacles due to the continued forward movement of the cleaning head 10 at this time, the nozzle 1021 is located at the thickness of the base 101 at this time. Specifically, on the plane perpendicular to the thickness direction of the base 101, the projection of the base 101 covers the projection of the nozzle assembly 102. Figure 6 , 9 As shown, the base 101 has a front end wall 1012 . When the suction nozzle 1021 is in the second position, the suction nozzle 1021 is substantially flush with the front end wall of the base 101 .

[0046] When the nozzle assembly 102 is in the first position, there is a gap 1013 between the nozzle 1021 and the front end wall 1012 of the base 101. The gap 1013 exists to prevent the nozzle assembly 102 from interfering with the base 101 when moving from the first position to the second position, and to keep the replaceable cleaning cloth installed at the bottom of the base 101 away from the nozzle 1021.

[0047] Further, the cleaning head 10 also includes a connecting portion 105 connected to the handle body portion 20. Further, referring to Figure 6 and Figure 7The connecting part 105 includes a connector 1051, a release button 1052 and a fixing part 1053, wherein the release button 1052 is located on the connector 1051. The user presses the release button 1052 to disassemble the cleaning head 10 and the handle body part 20. The connector 1051 is rotatably connected to the fixing part 1053, and the fixing part 1053 is fixedly set on the base 101. Therefore, when cleaning, the user rotates the handle body part 20 to drive the connector 1051 to rotate relative to the fixing part 1053, thereby realizing the rotation of the handle body part 20 relative to the cleaning head 10.

[0048] The cleaning head 10 further includes a first spring component (not shown in the figure). When the mounting arm 1022 is released by the locking member 103, the first spring component provides a reset force that causes the mounting arm 1022 to drive the suction nozzle assembly 102 to the second position. In some embodiments, the mounting arm 1022 is mounted on the fixing member 1053 and is rotatably connected to the fixing member 1053. The fixing member 1053 has a mounting groove. The first spring component is located in the mounting groove and abuts against the mounting arm 1022. Furthermore, the first spring component is a torsion spring. When the suction nozzle assembly 102 is in the first position, the torsion spring is squeezed. When the mounting arm 1022 is released by the locking member 103, the torsion spring releases its pressure to drive the mounting arm 1022 to swing upward, thereby driving the suction nozzle assembly 102 to move to the second position.

[0049] The cleaning head 10 further includes a second spring component 106, and the lock member 103 is supported on the base 101 by the second spring component 106. Exemplarily, one lock member 103 corresponds to at least one second spring component 106, so the second spring component 106 can be one or more. In some embodiments, a receiving groove 107 for placing the second spring component 106 is also provided on the base 101, and one receiving groove 107 can accommodate one second spring component 106 or multiple second spring components 106.

[0050] The actuating member 104 further includes a third spring component 1044. The actuating member 104 is supported on the nozzle assembly 102 by the third elastic component. The number of the third spring component 1044 can be one or more. Figures 6 to 10 , the number of mounting arms 1022 is 2, the actuating member 104 further includes a second member 1043, a third spring component 1044 and a guide column 1045, wherein the second member 1043 is connected to the first member 1041 and extends along the front-to-back direction, the third spring component 1044 and the guide column 1045 are both located behind the first member 1041, and one end of the third spring component 1044 is penetrated through the guide column 1045, and the other end is penetrated through the rearward extending limiter provided on the first member 1041; the second member 1043 corresponds to the locking member 103 one by one, Figure 6In the embodiment, the number of the second components 1043 is two, and the number of the third spring portions 1044 is two.

[0051] In some embodiments, in combination Figures 6 to 10 , the number of mounting arms 1022 is 2. When the suction nozzle assembly 102 is located in the first position, the rear end portion 10431 of the second component 1043 abuts against the locking component 103. When the protrusion 1042 touches an obstacle, the protrusion 1042 moves backward, driving the first component 1041 to move backward, and then driving the second component 1043 to move backward. The rear end portion 10431 of the second component 1043 pushes the locking component 103, thereby triggering the unlocking of the mounting arm 1022. During this process, the first component 1041 squeezes the third spring component 1044, and the guide column 1045 serves to limit and guide the third spring component 1044. After the locking component 103 releases the mounting arm 1022, the third spring component 1044 provides a force to reset the actuating component 104.

[0052] In some embodiments, in combination Figures 6 to 10, the number of the mounting arms 1022 is 2, the lock member 103 includes a trigger portion 1031, a hook portion 1032 and a main body portion 1033, the trigger portion 1031 and the hook portion 1032 both extend from the main body portion 1033 toward the mounting arm 1022, and the trigger portion 1031 is located above the hook portion 1032 as a whole. The trigger portion 1031 and the rear end portion 10431 of the second member 1043 contact and cooperate with each other, thereby triggering the release of the mounting arm 1022, illustratively, the trigger portion 1031 has a first inclined surface, and the rear end portion 10431 has a second inclined surface, and the first inclined surface and the second inclined surface cooperate with each other to convert the movement of the second member 1043 in the front-to-back direction into the movement of the main body portion 1033 in the left-to-right direction. The mounting arm 1022 has a groove 10221. When the nozzle assembly 102 is located at the first position, one end of the mounting arm 1022 is located in the groove 10221. In the left-right direction, the depth of the groove 10221 is less than or equal to the thickness of the mounting arm 1022. When the protrusion 1042 touches an obstacle, the second member 1043 moves backward, and the rear end 10431 of the second member 1043 pushes the trigger part 1031. The trigger part 1031 converts the movement in the front-to-back direction into the movement in the left-to-right direction, driving the main body 1033 to move in the first direction as a whole and compressing the second spring component 106. The hook 1032 is separated from the groove 10221 to release the mounting arm 1022, so that the nozzle assembly 102 moves to the second position as a whole, wherein the first direction is the direction away from the mounting arm 1022. At the same time, the second spring component 106 releases its stress to drive the main body 1033 and the hook 1032 to move in the second direction, wherein the second direction is the opposite direction of the first direction. When the suction nozzle assembly 102 needs to be restored to the first position again, the user presses the suction nozzle assembly 102 by hand or steps on the foot. When the mounting arm 1022 moves downward and the lower surface contacts the hook 1032, the hook 1032 is squeezed inward to make it move in the first direction until it returns to the groove 1022 to lock the mounting arm 1022. At this time, the suction nozzle assembly 102 is reset.

[0053] The above introduces a method of releasing and locking the mounting arm by mechanically cooperating the groove 10221 and the hook 1032. In some embodiments, the groove 10221 and the hook 1032 can be replaced by two magnetic components. When the main body 1033 moves in the first direction as a whole, the magnetic attraction of the two magnetic components is overcome, so that the mounting arm 1022 is released. When the mounting arm 1022 moves downward, the attraction of the two magnetic components drives the main body 1033 to move in the second direction, so that the two magnetic components are attracted to each other, thereby achieving the locking of the mounting arm 1022.

[0054] like Fig.13As shown, in some embodiments, a dirty air inlet 10211 with a relatively large width is provided below the front wall of the suction nozzle 1021, so that large particles can be sucked into the suction nozzle 1021, and corresponding sealing strips are provided below the rear wall, left wall and right wall of the suction nozzle 1021 to achieve better air duct sealing.

[0055] The working principle of the above-mentioned cleaning head 10 is as follows: when the user pushes the cleaning device 100 to move forward for cleaning, when the cleaning head 10 touches an obstacle such as a wall or furniture, the protrusion 1042 on the actuating member 104 collides with the obstacle before the suction nozzle 1021, and the actuating member 104 moves horizontally from the first actuating position to the second actuating position, and at the same time causes the locking member 103 to release the mounting arm 1022, so that the mounting arm 1022 drives the suction nozzle 1021 to move from the first position to the second position. At this time, the suction nozzle assembly 102 is lifted and is higher than the base 101 as a whole. The user can push the base 101 to continue to move forward, so that the cleaning sheet can clean corners such as wall corners. After the user finishes cleaning corners such as wall corners, he presses or steps on the suction nozzle assembly 102 by hand. When the mounting arm 1022 moves downward, the locking member 103 re-locks the mounting arm 1022, so that the suction nozzle assembly 102 remains in the first position, and normal cleaning can be achieved.

[0056] When the cleaning head 10 is used to clean the floor, if the suction nozzle 1021 is needed to suck up dust, the portable handheld host 30 will be fixed in the cavity 203; and when the user needs to use the portable handheld host 30 to clean directly, the user uses the handle 2052 to pull the upper retaining seat 205 upwards, so that the upper retaining seat 205 is disengaged from the lower limit member 206, and the portable handheld host 30 can be removed for use. At this time, the user can use the suction nozzle 32 to directly suck up dust or assemble a suction nozzle tool (not shown in the figure) at the suction nozzle 32 for dust suction.

[0057] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present application. Without departing from the spirit and scope of the present application, the present application may have various changes and improvements, and the scope of protection required by the present application is defined by the attached claims, description and their equivalents.
