Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and in particular to cleaning equipment. Background Technology

[0002] As people's living standards continue to improve, vacuum cleaners have gradually entered thousands of households, bringing great convenience to people's lives. However, current vacuum cleaners are generally large in size, taking up a lot of space after transportation or daily use. As a result, foldable vacuum cleaners have appeared on the market. In normal use, the upper and lower bodies are connected as a whole, and the vacuum cleaner works normally. In the storage state, the upper body rotates relative to the lower body and fits against one side of the lower body. However, during the process of changing from normal use to storage, dust and other debris in the dust cup are prone to being poured into the cyclone separation chamber at the top. When the vacuum cleaner is changed back to normal use, it affects the normal operation of the dust cup module, thus affecting the cleaning efficiency and reliability of the cleaning equipment.

The second cleaning module and the first cleaning module are arranged sequentially along the fluid recovery path, and part of the second cleaning module passes through the first cleaning module and connects to the dust cup module. In the disassembled state, the second cleaning module is separated from the dust cup module.

[0043] In one embodiment, the distance between the end of the lower body facing the upper body and the end of the first cleaning module facing away from the upper body is defined as a first length; the first length is greater than or equal to the length between the two ends of the upper body.

[0044] In one embodiment, the cleaning device further includes a handle assembly, which includes a handle and is disposed on the lower body.

[0045] In one embodiment, both the upper and lower housings are constructed as hood-like members with one end open;

[0046] The dust cup module includes a filter and a tubular extension shroud extending from the filter toward the upper body. The side of the extension shroud facing away from the dust cup module forms the outlet of the dust cup module.

[0047] The extension cover is located inside the open end of the lower housing. The handle is rotatably connected to the extension cover and is located in the annular handle receiving cavity defined by the extension cover and the lower housing.

[0056] The first axis is located on the first side of the second axis.

[0057] The beneficial effects of the above-mentioned cleaning equipment:

[0058] The upper and lower bodies are pivotally connected, allowing the upper body to fold relative to the lower body, thus reducing the space occupied by the cleaning equipment in its folded state. Furthermore, unlike related technologies where the dust cup rotates and dust stored at the bottom is poured to the top when the cleaning equipment is folded, in this embodiment, the dust cup module is housed within the lower housing. During folding, the upper body rotates relative to the lower body, but the position of the dust cup module on the lower body remains unchanged, preventing it from being inverted and effectively avoiding the spillage of dirt from the bottom of the dust cup module to the top. When the upper and lower bodies return to their first state, the working state of the dust cup module remains unaffected, ensuring high cleaning efficiency and reliability of the cleaning equipment.

[0059] Additionally, in normal use, the upper unit is positioned above the lower unit, closer to the user's head. In the first state, the upper housing covers the lower housing, and the motor and dust cup module are in fluid communication. This allows the motor to provide suction to draw dirt from the area to be cleaned into the dust cup module. Attached Figure Description

[0095] Reference Figure 1 , Figure 2 , Figure 3 The cleaning device 100 of this application embodiment includes a locking component 10 and an upper body 20 and a lower body 50 pivotally connected to each other.

[0096] The upper body 20 includes an upper housing 21 and a motor 70 housed within the upper housing 21. The lower body 50 includes a lower housing 51 and a dust cup module 80 housed within the lower housing 51. The motor 70 provides suction to draw dirt from the area to be cleaned into the dust cup module 80. The locking assembly 10 locks the upper body 20 and the lower body 50 together. Figure 1 , Figure 3 In the first state shown, the upper housing 21 covers the lower housing 51, and the motor 70 and the dust cup module 80 are in fluid communication.

[0097] In addition, the cleaning equipment 100 also includes a hinge assembly 30, through which the upper body 20 and the lower body 50 are pivotally connected.

[0098] The upper body 20 and lower body 50 are pivotally connected, allowing the upper body 20 to fold relative to the lower body 50, thereby reducing the space occupied by the cleaning device 100 in its folded state. Furthermore, compared to related technologies where the dust cup rotates and dust stored at the bottom is poured to the top when the cleaning device is folded, in this embodiment, the dust cup module 80 is housed within the lower housing 51. When folded, the upper body 20 rotates relative to the lower body 50, but the position of the dust cup module 80 on the lower body 50 remains unchanged, and it is not inverted, effectively preventing dirt from the bottom of the dust cup module 80 from being poured to the top. When the upper body 20 and lower body 50 are returned to their first state, the working state of the dust cup module 80 is unaffected, ensuring high cleaning efficiency and reliability of the cleaning device 100.

[0099] In addition, under normal operating conditions, the upper body 20 is positioned above the lower body 50, and is closer to the head than the lower body 50. In the first state, the upper housing 21 covers the lower housing 51, and the motor 70 is fluidly connected to the dust cup module 80. Thus, the motor 70 provides suction to draw dirt from the area to be cleaned into the dust cup module 80. Both the upper housing 21 and the lower housing 51 can, for example, be constructed with an open-end cavity. The upper housing 21 covers the lower housing 51, or the open ends of the upper housing 21 and the lower housing 51 can face each other, and the cavities of the upper housing 21 and the lower housing 51 can be combined to form a larger cavity. The fluid connection between the motor 70 and the dust cup module 80 can be achieved by connecting the inlet of the motor 70 to the outlet 81 of the dust cup module.

[0100] Furthermore, the upper fuselage 20 and the lower fuselage 50 also include a second state in which they are separated from each other, such as... Figure 2 As shown, in the second state, the upper housing 21 is separated from the lower housing 51, and the motor 70 is fluidly disconnected from the dust cup module 80. Specifically, the upper housing 21 can be flipped over and attached to the side of the lower housing 51.

[0101] In the second state, the motor 70 is fluidly disconnected from the dust cup module 80, and the cleaning device 100 is in a non-working state. This avoids the problem of repeated bending of the connection channel between the motor 70 and the dust cup module 80, which could easily lead to breakage. It is understood that in the first state, the openings of the upper housing 21 and the lower housing 51 are joined together. In the second state, the upper housing 21 rotates relative to the lower housing 51, causing the openings of both the upper housing 21 and the lower housing 51 to become open.

[0102] The structure of locking component 10 is described below. (Refer to...) Figure 4 and Figure 5 , Figure 4For ease of observation, the upper casing 21 is omitted. Figure 4 The image at the top of the middle panel represents the first state. Figure 4 The image below shows the second state. The locking assembly 10 includes a pressing member 11, which has a first mating part 111 and a second mating part 112.

[0103] The first mating part 111 is connected to one of the upper fuselage 20 and the lower fuselage 50, and the second mating part 112 is engaged with the other of the upper fuselage 20 and the lower fuselage 50.

[0104] With this configuration, the upper and lower fuselage 20 can be locked together simply by engaging the second mating part 112 with the other of the upper and lower fuselage 50. When the engagement is released, the upper fuselage 20 can rotate relative to the lower fuselage 50 for folding. Specifically, the first mating part 111 can be connected to the upper fuselage 20, and the second mating part 112 can be engaged with the lower fuselage 50; alternatively, the first mating part 111 can be connected to the lower fuselage 50, and the second mating part 112 can be engaged with the upper fuselage 20.

[0105] Furthermore, the locking assembly 10 also includes a first elastic member 12, the two ends of which are respectively connected to one end of the upper body 20 and one end of the pressing member 11, and always apply an elastic force away from the upper body 20 to the pressing member 11. A second mating part 112 is connected to the other end of the pressing member 11 and engages with the lower body 50. The first mating part 111 is located between the two ends of the pressing member 11 and is rotatably connected to the upper body 20.

[0106] With this configuration, since the first elastic member 12 always applies an elastic force away from the upper body 20 to one end of the pressing member 11, and the part between the two ends of the pressing member 11 is rotatably connected to the upper body 20 through the first mating part 111, the second mating part 112 connected to the other end of the pressing member 11 has a tendency to move in the direction of the lower body 50. In addition, the second mating part 112 is engaged with the lower body 50, so the second mating part 112 can be firmly fixed in the engagement position.

[0107] In practice, the first mating part 111, the second mating part 112 and the first elastic member 12 are all located on the same side of the pressing member 11, that is, on the side of the pressing member 11 facing the upper body 20 and the lower body 50.

[0108] In this embodiment of the application, combined with Figure 3 and Figure 4The upper housing 21 has a first outer shell 22 on its outer side, which together with the upper housing 21 defines a first mounting cavity 97. The first elastic member 12 and the pressing member 11 are installed in the first mounting cavity 97. The upper housing 21 has a first clearance notch 211 corresponding to the position of the pressing member 11. The first mating part 111 passes through the first clearance notch 211 and is rotatably connected to the upper housing 21. The first elastic member 12 is located in the first clearance notch 211.

[0109] With this configuration, the pressing part 11 can be exposed to the outside through the first clearance notch 211 for the operator to press, and the first mating part 111 will also be blocked between the pressing part 11 and the upper housing 21.

[0110] Furthermore, there are two first mating parts 111, which are arranged alternately. The outer wall of the upper housing 21 is provided with two spaced-apart support arms 212, and the two first mating parts 111 are hinged to the two support arms 212 in a one-to-one correspondence. This arrangement allows the two first mating parts 111 to be hinged to their respective support arms 212. Of course, the end of the first mating part 111 facing the support arm 212 is provided with a hinge shaft 1111, and the corresponding support arm 212 is provided with a mating hole 1112. The hinge shaft 1111 is inserted into the mating hole 1112 and can rotate relative to the mating hole 1112. The mating arrangement between the second mating part 112 and the support arm 212 is similar and will not be described further here.

[0111] In this embodiment, reference continues to be made to... Figure 3 The cleaning equipment 100 also includes a cleaning module 40. The upper body 20 also includes a control board (not shown) and an upper coupler 23, and the lower body 50 also includes a lower coupler 53. The upper coupler 23 and the motor 70 are electrically connected to the control board, and the lower coupler 53 is electrically connected to the cleaning module 40.

[0112] Reference Figure 4 In the first state, the upper coupler 23 and the lower coupler 53 are plugged into each other and electrically connected. In the second state, the upper coupler 23 is disconnected from the lower coupler 53 and electrically disconnected. The control board is used to stop the motor 70 when the upper coupler 23 and the lower coupler 53 are electrically disconnected. The upper coupler 23 can be, for example, a female plug-in terminal, and the lower coupler 53 can be, for example, a male plug-in terminal.

[0113] By configuring the upper coupler 23 and the lower coupler 53, and in the first state, the upper coupler 23 and the lower coupler 53 can be electrically connected to each other. Thus, in the first state, the control board achieves electrical connection with the cleaning module 40 through the electrical connection with the upper coupler 23, thereby enabling the cleaning device 100 to operate normally. In the second state, the upper coupler 23 and the lower coupler 53 are electrically disconnected, the control board controls the motor 70 to stop, and the connection between the control board and the cleaning module 40 is disconnected, so that both the motor 70 and the cleaning module 40 are in a stopped state. This is to prevent the motor 70 and the dust cup module 80 from remaining energized after the fluid connection between the motor 70 and the dust cup module 80, which could cause malfunctions, and to prevent foreign objects from being directly sucked into the motor 70 without passing through the dust cup module 80, thus preventing damage to the motor 70.

[0114] The upper coupler 23 can be mounted on the upper housing 21 using fasteners, such as screws, and the lower coupler 53 can be mounted on the lower housing 51 using fasteners, such as screws. Additionally, the cleaning module 40 may include a first cleaning module 41 and a second cleaning module 42.

[0115] Furthermore, when the first mating part 111 is connected to the upper fuselage 20, the lower coupler 53 is provided with a snap-fit ​​groove 531 at the position corresponding to the second mating part 112, and the snap-fit ​​groove 531 is used for the second mating part 112 to snap-fit.

[0116] In a specific implementation, the lower housing 51 is provided with a second outer shell 54, and the second outer shell 54 and the lower housing define a receiving cavity, in which the lower coupler 53 is installed. The second outer shell is provided with a second clearance notch 541 for the lower coupler 53 to be exposed. In addition, the upper coupler 23 can be installed in the first mounting cavity 97 defined by the first outer shell 22 and the upper housing 21.

[0117] Furthermore, referring to Figure 6 A first filter chamber 91 is formed inside the upper housing 21. A first filter element 221 is provided inside the first filter chamber 91. The outlet of the first filter chamber 91 is connected to the inlet of the motor 70.

[0118] In the second state, the first filter element 221 in the first filter chamber 91 can seal the inlet of the motor 70 to prevent foreign objects from entering the motor 70 from the inlet in the second state.

[0119] In the embodiments of this application, combined with Figure 3 and Figure 4In the first state, the outlet 81 of the dust cup module and the inlet 910 of the first filter chamber are both located between the hinge assembly 30 and the upper coupler 23 and the lower coupler 53. With this configuration, when the upper body 20 switches from the first state to the second state relative to the lower body 50, the upper coupler 23 and the lower coupler 53, being farther from the hinge assembly 30, will separate first, achieving electrical disconnection. Then, the outlet 81 of the dust cup module and the inlet 910 of the first filter chamber, which are closer to the hinge assembly 30, will separate. This allows the motor 70 to be de-energized before fluid disconnection between the motor 70 and the dust cup module 80, preventing malfunctions of the motor 70 before fluid disconnection, which could lead to foreign objects entering the motor 70.

[0120] In this embodiment of the application, combined with Figure 3 and Figure 7 The outlet 81 of the dust cup module and the inlet 910 of the first filter chamber are opposite to each other. In the first state, the outlet 81 of the dust cup module and the inlet 910 of the first filter chamber are sealed together by the first sealing member 52 so that the dust cup module 80 and the first filter chamber 91 are connected.

[0121] The cleaning device 100 also includes a battery 71, which can be electrically connected to the control board. The battery 71 is located on the side of the motor 70 away from the first filter chamber 91. In the second state, heavier components such as the battery 71 and the motor 70 can be located below the first filter chamber 91, so that the center of gravity is lowered and the operator is more stable when carrying the cleaning device 100 in the second state.

[0122] Furthermore, referring to Figure 7 The edge of the outlet 81 of the dust cup module defines a sealing installation groove 811, and the edge of the inlet 910 of the first filter chamber is inserted into the sealing installation groove 811 through the first seal 52.

[0123] With this configuration, in the first state, the first seal 52 can achieve a seal between the inlet 910 of the first filter chamber and the outlet 81 of the dust cup module. In the second state, when the upper body 20 is folded relative to the lower body 50, the first seal 52 is installed in the seal mounting groove 811 and is not easily dislodged.

[0124] Furthermore, referring to Figure 6 The upper body 20 also includes a support cover 24, one end of which is connected to a support mesh 25. The support mesh 25 and the support cover 24 are located inside the upper housing 21. The support mesh 25 and the inner wall of the upper housing 21 together define an annular first filter mounting cavity 92, in which the first filter 221 is installed. The support cover 24 protrudes from the first filter 221 along the length of the cleaning equipment 100 and is connected to the inlet of the motor 70.

[0125] With this configuration, the fluid to be filtered from the outlet 81 of the dust cup module passes through the annular first filter mounting cavity 92. After being filtered by the first filter 221, the fluid enters the inner side of the support mesh 25 and then passes through the support cover 24 before entering the inlet of the motor 70. At this time, the space inside the first filter mounting cavity 92, the space inside the support mesh 25, and the space inside the support cover 24 together define the first filter cavity 91.

[0126] Furthermore, an annular second filter chamber 93 is defined between the support cover 24 and the upper housing 21. The second filter chamber 93 is provided with a second filter element 222. The second filter chamber 93 is connected to the air outlet of the motor 70 and the outside.

[0127] With this configuration, the gas from motor 70 is discharged downwards, filtered by the second filter element 222 after passing through the second filter chamber 93, and then discharged to the outside. Of course, the upper housing 21 can be provided with multiple openings 210 corresponding to the position of the second filter element 222 to allow gas to flow out of the second filter chamber 93.

[0128] The structure of the hinge assembly 30 is described below. As mentioned earlier, the upper fuselage 20 and the lower fuselage 50 are pivotally connected by the hinge assembly 30.

[0129] Figure 8 and Figure 9 In the diagram, the left side shows a schematic diagram of the hinge assembly 30 in its first state, and the right side shows a schematic diagram of the hinge assembly 30 in its second state. (Refer to...) Figure 8 and Figure 9 The hinge assembly 30 includes an upper base 33 and a lower base 34, two first hinge arms 31 and two second hinge arms 32.

[0130] The upper base 33 and the lower base 34 are respectively connected to the upper fuselage 20 and the lower fuselage 50.

[0131] Two first hinge arms 31 are arranged opposite each other, and two second hinge arms 32 are respectively arranged on the inner sides of the two facing first hinge arms 31. The first ends 311 of the two first hinge arms are hinged to the first shaft 351, and the second ends 312 of the two first hinge arms are respectively hinged to the lower base 34 through the second shaft 352. The first ends 321 of the two second hinge arms are hinged to the third shaft 353, and the second ends 322 of the two second hinge arms are respectively hinged to the lower base 34 through the fourth shaft 354. The middle parts of the corresponding first hinge arms 31 and second hinge arms 32 are hinged to each other through the fifth shaft 355. This arrangement allows for a smaller hinge structure size and a larger rotation angle between the upper base 33 and the lower base 34.

[0132] Furthermore, the upper base 33 is provided with first slide rails 331 at the positions corresponding to both ends of the first shaft 351, and the lower base 34 is provided with two second slide rails 341 at the positions corresponding to the fourth shaft 354. The two ends of the first shaft 351 are slidably connected to the two first slide rails 331, and the two ends of the fourth shaft 354 are slidably connected to the two second slide rails 341.

[0133] With this configuration, the first slide rail 331 can limit the first end 311 of the first hinge arm, so that the first end 311 of the first hinge arm can move along the extension direction of the first slide rail 331, and the second slide rail 341 can limit the second end 322 of the second hinge arm, so that the second end 322 of the second hinge arm can move along the extension direction of the second slide rail 341.

[0134] In specific operation, when the upper base 33 rotates relative to the lower base 34, the fourth shaft 354, driven by the second hinge arm 32, moves along the extension direction of the second slide rail 341. The second end 322 of the second hinge arm moves upward along the extension direction of the second slide rail 341, and the second hinge arm 32 also rotates around the fifth shaft 355. At this time, the first shaft 351, driven by the first hinge arm 31, moves along the extension direction of the first slide rail 331. The first end 311 of the first hinge arm moves along the extension direction of the first slide rail 331, and the first hinge arm 31 also rotates around the fifth shaft 355 until the second end 322 of the second hinge arm moves to the corresponding position at the end of the second slide rail 341, and the first end 311 of the first hinge arm moves to the corresponding position at the end of the first slide rail 331. Figure 8 , 9 As shown in the diagram on the right, the upper base 33 has rotated to its position relative to the lower base 34, and the upper fuselage 20 has also rotated to its position relative to the lower fuselage 50.

[0135] Both the first hinge arm 31 and the second hinge arm 32 can be in the shape of the English letter "C". The upper base 33 can be connected to the upper housing 21, and the lower base 34 can be connected to the lower housing 51.

[0136] Furthermore, the hinge assembly 30 also includes an intermediate body 36, which is sandwiched between two second hinge arms 32 and is hinged to the third axis 353, the fifth axis 355 and the fourth axis 354 respectively.

[0137] With this configuration, the intermediate body 36 is isolated between the two second hinge arms 32, which helps to maintain the spacing between the two second hinge arms 32 and improves the reliability of the hinge assembly 30 during operation.

[0138] Furthermore, one of the upper substrate 33 and the lower substrate 34 is provided with a insertion slot 330, and the other is provided with a corresponding insertion block 340 that can be inserted into the insertion slot 330. In the first state, the insertion block 340 is inserted into the corresponding insertion slot 330. This arrangement allows the insertion slot 330 and the insertion block 340 to assist in positioning in the first state, preventing the upper substrate 33 and the lower substrate 34 from rotating relative to each other.

[0139] In the embodiments of this application, reference is made to Figure 10 The first shaft 351 and the second shaft 352 are respectively provided with a first shoulder structure 3510 and a second shoulder structure 3520 at both ends.

[0140] In the first ends 311 of the two first hinge arms, the facing wall portions abut against the two first shoulder structures 3510. In the second ends 312 of the two first hinge arms, the facing wall portions abut against the two second shoulder structures 3520.

[0141] The third shaft 353 and the fourth shaft 354 are respectively provided with a third shoulder structure 3530 and a fourth shoulder structure 3540 at their two ends. The facing walls of the first ends 321 of the two second hinge arms abut against the two third shoulder structures 3530. The facing walls of the second ends 322 of the two second hinge arms abut against the two fourth shoulder structures 3540.

[0142] With this configuration, the first shoulder structure 3510 and the second shoulder structure 3520 are used to position the two first hinge arms 31, and the third shoulder structure 3530 and the fourth shoulder structure 3540 are used to position the two second hinge arms 32.

[0143] In this embodiment of the application, combined with Figure 2 and Figure 3 As mentioned above, the cleaning module 40 includes a first cleaning module 41 and a second cleaning module 42. The first cleaning module 41 is connected to the dust cup module 80, and the second cleaning module 42 is detachably installed in the dust cup module 80 to have... Figure 2 The installation status shown is the same as Figure 3 The disassembly state is shown.

[0144] In the installed state, the second cleaning module 42 is installed on 51 and communicates with the dust cup module 80. The cleaning device 100 has a fluid recovery path. The second cleaning module 42 and the first cleaning module 41 are arranged sequentially along the fluid recovery path, and a portion of the second cleaning module 42 passes through the first cleaning module 41 and communicates with the dust cup module 80. In the disassembled state, the second cleaning module 42 is separated from the dust cup module 80.

[0145] With this configuration, in the disassembled state, the second cleaning module 42 is separated from the dust cup module 80, allowing the first cleaning module 41 to be used alone for localized cleaning. In the installed state, the second cleaning module 42 and the first cleaning module 41 are arranged sequentially along the fluid recovery path, with a portion of the second cleaning module 42 passing through the first cleaning module 41 and communicating with the dust cup module 80. Therefore, the mixture of debris and airflow can be sucked in from the second cleaning module 42 and flow directly into the dust cup module 80. Thus, in the installed state, with a portion of the second cleaning module 42 communicating with the first cleaning module 41 and the dust cup module 80, there is only a sealing requirement between the second cleaning module 42 and the dust cup module 80. The fluid only passes through one uneven point on the flow path, making the flow path relatively smoother. This allows for smoother fluid flow, less energy loss, and enables the second cleaning module 42 to provide stronger suction, resulting in higher cleaning efficiency.

[0146] In the embodiments of this application, reference is made to Figure 1 , Figure 2 The distance between the end of the lower body 50 facing the upper body 20 and the end of the first cleaning module 41 facing away from the upper body 20 is defined as the first length L1; the first length L1 is greater than or equal to the second length L2 between the two ends of the upper body 20.

[0147] In other words, the folding point of the upper body 20 and the lower body 50 is located closer to the motor 70 within the entire cleaning device 100. This arrangement allows the overall size of the cleaning device 100 to be smaller when the second cleaning module 42 is installed. Furthermore, preferably, when the first length L1 is approximately equal to the length between the two ends of the upper body 20, the folding state of the assembly consisting of the upper body 20, the lower body 50, and the first cleaning module 41 is essentially half-folded when the second cleaning module 42 is disassembled, further reducing the overall storage size of the cleaning device 100. Specifically, the second length L2 of the upper body 20 can be, for example, 504 mm, and the first length L1 can be, for example, 446 mm. The length L3 of the second cleaning module 42 can be, for example, 281 mm.

[0148] In the embodiments of this application, reference is made to Figure 4 , Figure 11 The cleaning equipment 100 also includes a handle assembly 60, which includes a handle 61 and is disposed in the lower body 50. The lower body 50 has a handle receiving cavity 94. This arrangement allows the cleaning equipment to be lifted and transported by operating the handle 61 when the upper body 20 is folded relative to the lower body 50.

[0149] In some embodiments, the handle 61 includes a base portion 614 and two extension portions 615 connected to two opposite ends of the base portion 614, such that the handle 61 is configured as a semi-closed structure with an opening. In a first state, the state of the handle 61 is referenced. Figure 12 As shown in the lower figure, the opening of the handle 61 faces the hinge assembly 30.

[0150] With this configuration, during the transition from the second state to the first state, the pressing member 26 inside the upper body 20 can press against the handle 61. As the upper body 20 rotates, the pressing member 26 can press the handle 61 to rotate away from the hinge assembly 30 into the handle receiving cavity 94. In a specific implementation, the handle 61 can be constructed as a "U" or "C" shaped structure.

[0151] Furthermore, referring to Figure 11 Both the upper housing 21 and the lower housing 51 are constructed as cover-shaped parts with one end open.

[0152] The dust cup module 80 includes a filter 83 and a tubular extension hood 82 extending toward the upper body 20, with the side end of the extension hood 82 facing away from the dust cup module 80 forming the outlet 81 of the dust cup module.

[0153] The extension cover 82 is located inside the open end of the lower housing 51, and the handle 61 is rotatably connected to the extension cover 82 and located in the annular handle receiving cavity 94 defined by the extension cover 82 and the lower housing 51.

[0154] With this configuration, when the cleaning device 100 is in the first state, the handle 61 can be stored in the handle receiving cavity 94, such as... Figure 12 As shown in the lower part of the diagram, when the upper body 20 is folded relative to the lower body 50, the handle 61 protrudes from the lower housing, facilitating lifting by the operator. Figure 12 The image shown is located on the upper part of the middle section.

[0155] Reference Figure 11 and Figure 12 The lower housing 51 defines an open lower receiving cavity 96, and the upper housing 21 defines an open upper receiving cavity 95. A dust cup module 80 is disposed in the lower receiving cavity 96. The dust cup module 80 includes a filter 83. After the mixture of debris and airflow from the first cleaning module 41 or the second cleaning module 42 enters the lower receiving cavity 96, it is filtered and separated by the filter 83. The debris falls downwards under gravity and accumulates at the bottom of the lower receiving cavity 96. The airflow flows through the filter 83, moves upwards from inside the filter 83, passes through the extension cover 82, and enters the motor 70 of the upper housing 20. The extension cover 82 connects the dust cup module 80 and the motor 70, functioning as part of the airflow passage.

[0156] Furthermore, referring to Figure 12 , Figure 13 , Figure 14 , Figure 15 The handle assembly 60 also includes an elastic reset member 62, which is connected to the handle 61 and the extension cover 82 respectively. The elastic reset member 62 is used to always apply an elastic force to the handle 61 to make the handle 61 stand up.

[0157] With this configuration, when the upper body 20 and lower body 50 are in the second state, the handle 61 can always be in an upright state under the action of the elastic reset member 62, making it convenient for the operator to grip. In the first state, the upper body 20 presses against the handle 61 so that the handle 61 is housed in the handle receiving cavity 94.

[0158] Furthermore, the handle 61 is rotatably connected to the extension cover 82 about the first axis O1, and the elastic reset member 62 is connected to the handle 61 and the extension cover 82 respectively, and is used to apply a rotational force about the first axis O1 to the handle 61.

[0159] With this configuration, when the upper body 20 and the lower body 50 are in the second state, the handle 61 can always be in an upright state under the rotational force of the elastic reset member 62 around the first axis O1, making it convenient for the operator to grip.

[0160] In a specific implementation, the elastic reset element 62 can be a torsion spring. The handle 61 is semi-circular in shape, and its two ends are respectively connected to the opposite sides of the extension cover 82 via an elastic reset element 62. This arrangement facilitates the storage of the handle 61 within the annular handle receiving cavity 94.

[0161] In this embodiment, reference continues to be made to... Figure 13 , Figure 14 , Figure 15 The handle 61 has a rotating connection part 611 at its end, which extends toward the extension cover 82 and is supported in the extension cover 82. The elastic reset member 62 is sleeved on the outside of the rotating connection part 611. The handle 61 has a locking groove 612 at its end, one end of the elastic reset member 62 is engaged in the locking groove 612, and the other end of the elastic reset member 62 is connected to the extension cover 82.

[0162] This configuration reliably connects the elastic reset member 62 between the handle 61 and the extension cover 82. Additionally, a limiting ring 613 is provided on the outer circumferential side of the rotating connection portion 611, and a stop ring 821 is provided on the extension cover 82 at a position corresponding to the limiting ring 613. The stop ring 821 is located on the outer circumferential side of the limiting ring 613. When the handle 61 rotates relative to the extension cover 82, the stop ring 821 blocks the outer circumferential side of the limiting ring 613, thus limiting the rotation of the limiting ring 613. A locking groove 612 can be provided on the limiting ring 613.

[0163] Furthermore, the end of the handle 61 is provided with a first stop 63, and the bottom wall of the handle receiving cavity 94 is provided with a second stop 64 corresponding to the position of the first stop 63. When the handle 61 is upright, the second stop 64 is positioned in front of the first stop 63 in the direction of rotation to restrict the rotation of the handle 61.

[0164] This configuration allows the handle 61 to remain upright without rotating back into the handle receiving cavity 94.

[0165] In this embodiment of the application, combined with Figure 11 The open end of the upper housing 21 is also connected to a pressing member 26. The pressing member 26 is located at a position corresponding to the handle receiving cavity 94. In the first state, the pressing member 26 presses against the handle 61 to overcome the elastic force of the elastic reset member 62 and limit the handle 61 to be located in the handle receiving cavity 94.

[0166] With this configuration, in the first state, the handle 61 can be accommodated in the handle accommodating cavity 94, and in the second state, the handle 61 stands upright under the elastic force of the elastic reset member 62.

[0167] Further, as previously described, the axis of rotation of the handle 61 relative to the extension cover 82 is defined as the first axis. The second cleaning module 42 is rotatably connected to the lower body 50 about the second axis. In the second state, the upper body 20 is pivoted relative to the lower body 50 and located on the first side of the lower body 50. The first axis is located on the first side of the second axis.

[0168] With this configuration, the handle 61 is positioned closer to the center of gravity of the cleaning equipment 100 in its second state, which is closer to the center of gravity of the entire machine. This configuration makes it easier for the operator to lift the handle.

[0169] The following is combined with Figure 3 , Figure 4 The working process of the cleaning device 100 in this application embodiment is explained as follows:

[0170] In the first state, the second mating part 112 of the pressing member 11 engages with the locking groove 531 of the lower coupler 53, locking the upper body 20 and the lower body 50 together and maintaining the first state. When the motor 70 is turned on, it provides suction force. The mixture of garbage and airflow enters the lower receiving cavity 96 in the lower housing 51 through the first cleaning module 41 or the second cleaning module 42. It is filtered and separated by the filter 83 in the lower receiving cavity 96. The garbage falls downward under the action of gravity and accumulates at the bottom of the lower receiving cavity 96. The airflow flows through the filter 83, moves upward from the inside of the filter 83, passes through the inside of the extension cover 82 and enters the first filtering cavity 91 of the upper body 20. The airflow filtered by the first filter element 221 enters the motor 70 through the inlet of the motor 70. The gas in the motor 70 then passes downward through the second filter element 222 and is discharged to the outside.

[0171] The operator operates the pressing component 11 to release the engagement between the second mating part 112 and the lower coupler 53. At this time, the upper body 20 is rotated relative to the lower body 50, and the upper coupler 23 and the lower coupler 53 are disconnected. The inlet 910 of the first filter chamber and the outlet 81 of the dust cup module are also fluidly disconnected, thus switching the upper body 20 and the lower body 50 to the second state. At this time, the handle 61 stands upright under the elastic force of the elastic reset component 62, allowing the operator to lift it. Of course, in the case of long-distance transportation or packaging of the cleaning equipment 100, the second cleaning module 42 can also be disassembled to further reduce the overall size of the machine.

[0172] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0173] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
