Therefore, a feature specified as "first" or "second" may explicitly include at least one of such features. In the description of this disclosure, "plurality" means at least two, such as two or three, and "several" means at least one, such as one, two, or three, unless otherwise specifically defined.

[0081] In this disclosure, unless otherwise expressly defined, the terms "installed," "connected," "connect," "fixed," and "disposed" should be interpreted broadly. For example, "connection" can mean fixed, removable, or integrated; mechanical or electrical; direct or indirect through an intermediary; or internal communication between two components or interaction between two components.

[0083] Take a steam mop as an example. The main unit is detachably mounted on the main unit. Assembling the main unit and the main unit is laborious. Furthermore, because the connection between the main unit and the main unit involves the steam nozzle and nozzle interface, frequent disassembly and assembly over time can wear out the nozzle seal.

[0084] The cleaning device of the embodiment of the present disclosure is not limited to a steam mop. For example, the cleaning device may also be a washing machine.

[0085] like Figures 1 to 6 As shown, an embodiment of the present disclosure provides a cleaning device, comprising: a body frame 110, a cover plate 130, and a first pipe 160. The cover plate 130 comprises a first portion 134 mounted on the body frame 110, and a second portion 133 connected to the first portion 134. The first pipe 160 is mounted on the body frame 110 and comprises a first mounting position 142 and an interface 141. The first mounting position 142 is connected to the outer wall of the interface 141 formed by the first pipe 160. The first mounting position 142 is sleeved with the second portion 133, and a floating gap 170 is formed between the first mounting position 142 and the second portion 133.

[0086] In the disclosed embodiment, a floating gap 170 is provided between the first mounting position 142 and the second portion 133. This floating gap 170 allows the first pipe 160 to oscillate. When the component to be assembled, equipped with the nozzle 210, is assembled with the first pipe 160, the first pipe 160 can oscillate to better accommodate the alignment of the component to be assembled at the assembly joint. This allows the nozzle 210 to be inserted into the interface 141 more quickly, reduces the number of times the nozzle 210 needs to be aligned with the interface 141, and reduces the difficulty of assembling the component to be assembled with the first pipe 160.

[0087] Moreover, since the first pipe 160 can shake, when the components to be assembled are assembled with the first pipe 160, this shaking allows for floating during the assembly process, increases the buffer, and can reduce damage to components such as the nozzle 210 and the first pipe 160 during the assembly process, which is beneficial to extending the service life of the cleaning equipment.

[0088] The fuselage 100 may include at least a fuselage frame 110 , a cover plate 130 and a first duct 160 .

[0089] Without limitation, the spray head 210 is used to atomize liquid to provide an atomized fluid for cleaning.

[0090] For example, the nozzle 210 can be integrated with the water tank 240 as part of the main assembly 200. Figure 1 As shown, the main unit assembly 200 can be used as a component to be assembled. When the main unit assembly 200 is assembled with the body 100 , the nozzle 210 needs to be inserted into the interface 141 at the assembly joint.

[0091] Optionally, the liquid in the water tank 240 can be directly connected to the nozzle 210, or the liquid in the water tank 240 is heated by the heating structure and then formed into an atomized fluid by the nozzle 210 and flows into the interface 141 of the first pipe 160, and then the atomized fluid continues to flow along the first pipe 160.

[0092] like Figures 2 to 4 As shown, the first mounting position 142 is adjacent to the interface 141, so the floating gap 170 is also adjacent to the interface 141. In other words, the first mounting position 142 is adjacent to the assembly joint, which can better realize the shaking of the first pipe 160 at the interface 141, making the assembly of the main assembly 200 and the fuselage 100 easier.

[0093] In some embodiments, the floating gap 170 is distributed along the circumference of the first mounting location 142 .

[0094] According to some optional embodiments, the first mounting position 142 includes a mounting hole, and the second part 133 includes a mounting post; or, the first mounting position includes a mounting post, and the second part includes a mounting hole; the mounting hole accommodates at least a portion of the mounting post, and the floating gap 170 is located between the inner wall of the mounting hole and the mounting post.

[0095] Figure 2 To the picture Figure 5 As exemplarily shown, the first mounting position 142 is a mounting hole, the second portion 133 is a mounting post, and a floating gap 170 is provided between the inner wall of the mounting hole and the outer surface of the mounting post.

[0096] In some embodiments, the number of the first installation positions 142 is two or more, and the two or more first installation positions 142 are distributed circumferentially along the outer wall of the interface 141 formed by the first pipe 160 .

[0097] According to some optional embodiments, the floating gap 170 is an annular gap.

[0098] For example, Figure 5 As shown, in the radial direction of the annular gap, the floating amount b of the annular gap is twice the distance a between the inner wall of the mounting hole and the outer surface of the mounting column, that is, b=2a.

[0099] Without limitation, the floating amount b of the floating gap 170 may be 1.5 mm to 2.5 mm. For example, the floating amount may be any value among 1.5 mm, 1.8 mm, 2.0 mm, 2.2 mm, or 2.5 mm, or any value between any two values.

[0100] In some embodiments, a distance a between an inner wall of the mounting hole and an outer surface of the mounting post is approximately 0.8 mm.

[0101] According to some optional embodiments, the first pipe 160 includes: a pipe 150 and a joint 140; wherein, the pipe 150 is installed on the fuselage frame 110, the joint 140 is connected to the pipe 150, the joint 140 has an interface 141, the interface 141 is connected to the pipe 150, and the first installation position 142 is located on the joint 140.

[0102] When the first mounting position 142 is a mounting hole, the first mounting position 142 is formed on the outer wall of the interface 141. When the first mounting position 142 is a mounting post, the first mounting position 142 and the outer wall of the interface 141 can be an integral component, that is, the mounting post can be integrally formed with the outer wall of the interface 141.

[0103] The first mounting position 142 is located at the joint 140, which can ensure that the first mounting position 142 is adjacent to the interface 141, so that the floating gap 170 is also adjacent to the interface 141, so that the shaking of the first pipe 160 at the interface 141 can be better realized, making the assembly of the main assembly 200 and the fuselage 100 easier.

[0104] The atomized fluid flowing out of the nozzle 210 can enter the pipeline 150 through the interface 141 .

[0105] In some embodiments, the pipe 150 may lead to the mop assembly 300 below the body 100 so that the floor brush in the mop assembly 300 may be soaked by the fluid from the pipe, thereby achieving the function of the floor brush cleaning the surface to be cleaned.

[0106] According to some optional embodiments, the first part 134 includes: an installation part 131 and a connecting part 132; wherein, the installation part 131 is connected to the fuselage frame 110, and the connecting part 132 is respectively connected to the installation part 131 and the second part 133, the connecting part 132 has an avoidance hole 1321, the joint 140 is partially located in the avoidance hole 1321, and the interface 141 of the joint 140 is coaxial with the avoidance hole 1321, and the joint 140 is located between the connecting part 132 and the pipe 150.

[0107] The mounting portion 131 is used to secure the cover plate 130 to the body frame 110. The avoidance hole 1321 of the connecting portion 132 allows the interface 141 to be exposed, facilitating the insertion of the connector 140.

[0108] The joint 140 is located between the connecting portion 132 and the pipe 150 , so that the joint 140 is not completely exposed to the external environment. The connecting portion 132 protects the joint 140 .

[0109] like Figures 2 to 4 As shown, in some embodiments, the connecting portion 132 protrudes toward the nozzle 210. This protruding connecting portion 132, such as Figure 10As shown, the location of the nozzle 210 in the main assembly 200 can be made into a recessed area 230 , which can reduce the protruding portion of the main assembly 200 .

[0110] In some usage scenarios, the main unit assembly 200 needs to be removed from the body 100 to change the usage mode. In this case, the fewer protrusions on the main unit assembly 200, the more conducive it is to reducing the bumps and bumps caused by the main unit assembly 200 during use.

[0111] According to some optional embodiments, the connector 140 includes: a main body 144 and at least two fixing ears 143 , the main body 144 has an interface 141 ; the at least two fixing ears 143 are distributed along the circumference of the main body 144 , and the fixing ears 143 have a first installation position 142 .

[0112] Figure 3 and Figure 4 Two mounting ears with mounting holes are shown as an example.

[0113] In addition, a mounting post may be provided on the fixing ear 143 as a first mounting position.

[0114] like Figure 9 、 Figure 10 and Figure 12a As shown, according to some optional embodiments, the body frame 110 further includes: a second mounting position 190 for supporting the host assembly 200 , and the interface 141 gradually tilts downward from the host assembly 200 toward the body frame 110 .

[0115] The components to be assembled with the first conduit 160 are generally assembled from top to bottom. The interface 141 is oriented downward, gradually approaching the fuselage frame 110. This tilted arrangement facilitates top-to-bottom assembly of the components to be assembled and helps reduce bending of the first conduit 160 during assembly, thereby reducing air congestion in the first conduit 160. In some embodiments, the angle between the interface 141 and the horizontal plane is 20°-40°, with an optimal value of 25°.

[0116] Exemplarily, the second mounting position 190 is a mounting groove.

[0117] like Figure 1 、 Figure 7 、 Figure 8 and Figure 10As shown, according to some optional embodiments, the cleaning device further includes: a main unit assembly 200, the main unit assembly 200 includes a bracket and a nozzle 210, and the nozzle 210 is mounted on the bracket; the main unit assembly 200 has at least a floor mopping state and a handheld state relative to the body frame 110; the main unit assembly 200 is in the floor mopping state, the main unit assembly 200 is mounted on the body frame 110, and the nozzle 210 is at least partially located in the interface 141; the main unit assembly 200 is in the handheld state, the main unit assembly 200 is separated from the body frame 110, and the nozzle 210 is connected to the nozzle 400.

[0118] When the main body assembly 200 is assembled to the body frame 110 and when the main body assembly 200 is detached from the body frame 110 , the cleaning device can have different operating modes. Figure 1 、 Figure 8 and Figure 11 The main body assembly 200 is exemplarily shown in a mopping state. Figure 7 The host assembly 200 is exemplarily shown in a handheld state.

[0119] The mopping mode is more suitable for cleaning larger surfaces. The handheld mode is more portable and can be used to clean narrow surfaces. Alternatively, if the nozzle 210 sprays a higher-temperature atomized fluid, the handheld mode can also be used for ironing clothes. The different modes of the main unit 200 can meet different usage needs and help improve the user experience.

[0120] like Figure 10 As shown, according to some optional embodiments, the nozzle 210 gradually tilts downward from the bracket toward the fuselage frame 110 , and its tilt angle is adapted to the tilt angle of the interface 141 .

[0121] When in handheld state, the nozzle 210 is gradually tilted downward from the bracket toward the body frame 110, so that the nozzle 210 can spray the atomized liquid downward instead of upward, which can reduce the harm of the atomized liquid to people in the handheld state and the backflow of condensed water.

[0122] The nozzle 210 that gradually tilts downward from the bracket to the fuselage frame 110 can be adapted to the interface 141 that gradually tilts downward from the main unit assembly 200 to the fuselage frame 110, which is beneficial to reduce the bending of the first pipe 160 and reduce the air holding problem of the first pipe 160.

[0123] like Figure 12aAs shown, according to some optional embodiments, the main unit assembly 200 further has the following transitional states relative to the body frame 110: a transitional state between the ground-mopping state and the handheld state; when the main unit assembly 200 is in the transitional state, the first end 207 of the bottom of the main unit assembly 200 contacts the second mounting position 190, a gap exists between the second end 208 of the bottom of the main unit assembly 200 and the second mounting position 190, and the second end 208 is located between the first end 207 and the body frame 110; and when the main unit assembly 200 is in the ground-mopping state, the second end 208 contacts the second mounting position 190. The transitional state is an intermediate state between the main unit assembly 200 being installed in the second mounting position 190 or being removed from the second mounting position 190.

[0124] The point where the first end 207 of the bottom of the main unit assembly 200 contacts the second mounting position 190 is the abutment point. This abutment point also serves as the fulcrum O for the main unit assembly 200 to rotate in a first direction when the main unit assembly 200 transitions from the handheld state to the floor-mopping state. Similarly, this abutment point also serves as the fulcrum O for the main unit assembly 200 to rotate in a second direction when the main unit assembly 200 transitions from the floor-mopping state to the handheld state. The first direction may be toward the cover plate 130 or the body frame 110, and the second direction may be away from the cover plate 130 or the body frame 110. The second direction is opposite to the first direction.

[0125] The main unit assembly 200 rotates around the abutment point (i.e., the fulcrum O) as the rotation center, and the second mounting position 190 can be used to bear part of the weight of the main unit assembly 200, making it easier for the main unit assembly 200 to switch between the handheld state and the ground mopping state, and also more convenient for the assembly of the main unit assembly 200 and the body frame 110.

[0126] like Figure 11 、 Figure 12a and Figure 13 As shown, the position of the fulcrum O is the contact position between the leftmost side of the bottom of the main assembly 200 and the leftmost side of the second installation position 190 .

[0127] like Figure 11 and Figure 12aAs shown, in the transition state, whether in the process of rotation along the first direction or the second direction, the rotation trajectory of the main unit component 200 is the trajectory circle P1P2 with the fulcrum O as the center, and the first axis L2 of the interface 141 and the second axis L1 of the nozzle 210 are both tangent to the same trajectory circle P1P2, and the radius of the trajectory circle P1P2 is: the distance P between the first axis L2 of the interface 141 and the fulcrum O or the distance P between the second axis L1 of the nozzle 210 and the fulcrum O (since the first axis L2 of the interface 141 and the second axis L1 of the nozzle 210 are both tangent to the trajectory circle P1P2, the distance between the first axis L2 of the interface 141 and the fulcrum O is equal to the distance between the second axis L1 of the nozzle 210 and the fulcrum O, both of which are P). Not only that, as Figure 12b As shown, the foot H1 (i.e., the tangent point) of the perpendicular from the fulcrum O to the first axis L2 is located within the length range of the interface 141 on the first axis L2 (it should be noted that this length range refers to the length of the channel of the interface 141 for docking with the nozzle 210, that is, the length A1A2 between the two opposite end points A1 and A2 of the internal channel of the interface 141 along its axis L2, as shown in FIG. Figure 12c As shown in FIG, the foot H2 (i.e., the tangent point) of the perpendicular from the fulcrum O to the second axis L1 is located within the length range of the nozzle 210 on the second axis L1 (it should be noted that: this length range refers to the length of the channel for the nozzle 210 to complete the docking with the interface 141, that is, the length B1B2 between the two opposite end points B1 and B2 of the internal channel of the nozzle 210 along its axis L1, as shown in FIG. Figure 12c This ensures that the nozzle 210 and the interface 141 are better connected, and the floating gap at the connection between the first pipe 160 and the cover plate 130 is more conducive to the connection.

[0128] In some optional embodiments, such as Figure 12b As shown, the foot H1 of the perpendicular from the fulcrum O to the first axis L2 coincides with the center point O1 of the length A1A2 of the interface 141 on the first axis L2, and the foot H2 of the perpendicular from the fulcrum O to the second axis L1 coincides with the center point O2 of the length B1B2 of the nozzle 210 on the second axis L1.

[0129] In some optional embodiments, the length A1A2 of the interface 141 along the first axis L2 is equal to the length B1B2 of the spray head 210 along the second axis L1.

[0130] For example, the smoothness of the nozzle 210 and the interface 141 when the main unit 200 transitions from the handheld state to the floor mopping state can only be guaranteed when the transition state satisfies the following two conditions: (1) The rotation trajectory of the main unit 200 is a trajectory circle P1P2 with the fulcrum O as the center, and the first axis L2 of the interface 141 channel and the second axis L1 of the nozzle 210 channel are both tangent to the same trajectory circle P1P2. (2) The foot H1 of the perpendicular from the fulcrum O to the first axis L2 is within the length range of the interface 141 on the first axis L2, and the foot H2 of the perpendicular from the fulcrum O to the second axis L1 is within the length range of the nozzle 210 on the second axis L1.

[0131] Furthermore, in order to improve the smoothness of the nozzle 210 and the interface 141, the following conditions may also be met: (3) the foot H1 of the perpendicular from the fulcrum O to the first axis L2 coincides with the center point O1 of the length A1A2 of the interface 141 on the first axis L2, and / or the foot H2 of the perpendicular from the fulcrum O to the second axis L1 coincides with the center point O2 of the length B1B2 of the nozzle 210 on the second axis L1.

[0132] Furthermore, in order to improve the smoothness of the nozzle 210 and the interface 141, the following conditions may be met: (4) the length A1A2 of the interface 141 on the first axis L2 is equal to the length B1B2 of the nozzle 210 on the second axis L1.

[0133] refer to Figure 11 and Figure 12a The present disclosure also provides a method for using a cleaning device, comprising the following steps:

[0134] S10, placing the first end 207 of the bottom of the main assembly 200 in contact with the body frame 110;

[0135] S20. With the contact point between the first end 207 and the body frame 110 as the fulcrum O, rotate the main unit assembly 200 toward the cover plate 130 located on the body frame 110 until the nozzle 210 on the main unit assembly 200 is inserted into the interface 141 of the first pipe 160 located on the cover plate 130; wherein, during the rotation process, the first axis L2 of the interface 141 channel and the second axis L1 of the nozzle 210 channel are both tangent to the same trajectory circle P1P2, the center of the trajectory circle P1P2 is the fulcrum O, and the foot H1 of the perpendicular from the fulcrum O to the first axis L2 is located within the length range of the interface 141 on the first axis L2, and the foot H2 of the perpendicular from the fulcrum O to the second axis L1 is located within the length range of the nozzle 210 on the second axis L1.

[0136] Steps S10 and S20 involve steps in the process of transforming the host assembly 200 from a handheld state to a ground-mopping state, and may also serve as steps in the process of installing the host assembly 200 on the body frame 110 .

[0137] The method of use may further include the steps of:

[0138] S30 , a floating gap is provided at the connection between the first pipe 160 and the cover plate 130 .

[0139] Furthermore, the method may further include the steps of:

[0140] S40, make the foot of the perpendicular H1 from the fulcrum O to the first axis L2 coincide with the center point O1 of the length A1A2 of the interface 141 on the first axis L2, and / or, make the foot of the perpendicular H2 from the fulcrum O to the second axis L1 coincide with the center point O2 of the length B1B2 of the nozzle 210 on the second axis L1.

[0141] Furthermore, the method may further include the steps of:

[0142] S50 , making the length A1A2 of the interface 141 on the first axis L2 equal to the length B1B2 of the nozzle 210 on the second axis L1 .

[0143] The present disclosure also provides a method for using a cleaning device, including:

[0144] S60: With the first end 207 of the bottom of the main assembly 200 and the contact point with the body frame 110 as the fulcrum O, the main assembly 200 is rotated in a direction away from the cover plate 130 on the body frame 110 until the nozzle 210 on the main assembly 200 is separated from the interface 141 of the first pipe 160 on the cover plate 130.

[0145] Step S60 involves the process of transforming the main unit assembly 200 from the ground-mopping state to the handheld state, and may also be the step of detaching the main unit assembly 200 from the body frame 110 .

[0146] In addition, step S60 may also be performed before step S10.

[0147] Figure 12a The figure shows a partial structural cross-sectional view of the cleaning device when the main body assembly 200 is in a transition state.

[0148] Taking the transition from the handheld state to the ground mopping state as an example, the first end 207 of the bottom of the main body assembly 200 can be placed against the second mounting position 190, while the second end 208 of the main body assembly 200 is suspended in the air. Then, the main body assembly 200 is rotated toward the body frame 110 with the first end 207 as the fulcrum O. Figure 12a This transition state can reduce the collision of the sealing ring between the nozzle 210 and the joint 140 during the assembly process, reduce the wear of the sealing ring, and extend the service life of the sealing ring.

[0149] The sealing ring between the nozzle 210 and the joint 140 can be installed on the joint 140 or on the nozzle 210 .

[0150] like Figure 10 、 Figure 12a and Figure 13 As shown, according to some optional embodiments, the first end 207 of the main unit component 200 has an adjacent first surface 205 and a second surface 204, and the second mounting position 190 has an adjacent third surface 191 and a fourth surface 192; when the main unit component 200 is in a mopping state, the first surface 205 abuts against the third surface 191, and the second surface 204 abuts against the fourth surface 192; when the main unit component 200 is in a transitional state, the distal end of the first surface 205 away from the second surface 204 abuts against the distal end of the third surface 191 away from the fourth surface 192, the proximal end of the first surface 205 adjacent to the second surface 204 and the middle part of the first surface 205 transitioning from the distal end to the proximal end are separated from the third surface 191, and the second surface 204 and the fourth surface 192 are also separated, and the distal end and the proximal end are opposite ends.

[0151] like Figure 13 As shown, for example, first end 207 of the bottom of mainframe assembly 200 has a groove, and first surface 205 and second surface 204 can be adjacent inner surfaces of the groove. Second mounting position 190 has a protrusion, and third surface 191 and fourth surface 192 are adjacent surfaces of the protrusion. When first end 207 of the bottom of mainframe assembly 200 abuts second mounting position 190, the protrusion is located within the groove, forming a fulcrum O on the protrusion. This approach ensures the stability of the abutment between mainframe assembly 200 and second mounting position 190 during transitional conditions.

[0152] Without limitation, the second mounting position 190 is a mounting slot. Figure 11 As shown, the main unit assembly 200 is in a mopping state, the second surface 204 is located in the mounting groove, the second surface 204 abuts against the side wall of the protrusion, and the first surface 205 abuts against the top wall of the protrusion.

[0153] The first surface 205 is perpendicular or approximately perpendicular to the second surface 204. The third surface 191 is perpendicular or approximately perpendicular to the fourth surface 192.

[0154] The point where the distal end of the first surface 205 abuts the third surface 191 serves as the pivot point (i.e., the aforementioned fulcrum O) during the transition from the transition state to the mopping state. The abutment between the second surface 204 and the fourth surface 192 reduces the wobble of the main unit assembly 200 in the second mounting position 190 during the mopping state, further strengthening the connection between the main unit assembly 200 and the body frame 110.

[0155] In one example, the cleaning device is a steam mop, such as Figure 12aAs shown, the main unit assembly 200 uses the point where the far end of the first surface 205 away from the second surface 204 abuts the third surface 191 as the rotation point, and moves tangentially toward the fuselage frame 110. This assembly process can alleviate the wear and tear caused to the joint 140 and the nozzle 210 during the assembly of the main unit assembly 200, which is beneficial to increase the service life of the cleaning equipment.

[0156] When the main unit assembly 200 is in a handheld state, the nozzle 400 can be connected to the spray head 210 so that the atomized liquid sprayed by the spray head 210 is sprayed through the nozzle 400, and the nozzle 400 can be used to achieve cleaning or ironing. Therefore, the nozzle 400 is an accessory that can be installed on the main unit assembly 200 after being removed from the main frame 110.

[0157] In some embodiments, as Figure 1 As shown, the nozzle 400 and the main body assembly 200 are respectively located on opposite sides of the body 100. This distribution can reduce the impact of the nozzle 400 on the main body assembly 200 and more reasonably utilize the space of the body 100.

[0158] like Figures 11 to 15 As shown, according to some optional embodiments, the main unit assembly 200 further includes: a shell 201, and located inside the shell 201: a water tank 240, a water pump 290, a heating structure 270, a second pipe 250, a third pipe 260 and a fourth pipe 280; wherein the heating structure 270 includes a pot body, and a heating element for heating the liquid entering the pot body; the water inlet of the second pipe 250 is connected to the water tank 240, the water outlet of the second pipe 250 is connected to the third pipe 260 through the water pump 290, and the third pipe 260 is connected to the water inlet end of the pot body; the water inlet hole of the fourth pipe 280 is connected to the water outlet end of the pot body, and the water outlet hole of the fourth pipe 280 is connected to the joint 140.

[0159] like Figures 11 to 14 and Figure 15 As shown, the water tank 240 is used to store cleaning liquid.

[0160] like Figure 14 As shown, a water pump 290 is used to power the flow of the cleaning liquid.

[0161] The heating structure 270 is used to heat the cleaning liquid transported through the second pipe 250 , the water pump 290 and the third pipe 260 , and to allow the heated cleaning liquid to flow out through the fourth pipe 280 .

[0162] The cleaning liquid is cold water. The cold water in the water tank 240 flows out from the water outlet pipe of the water tank 240 and reaches the water pump inlet 291 through the second pipe 250. Figure 14As shown by the downward arrow in the second pipe 250, the water flows through the water pump outlet to the third pipe 260, and then enters the pot body through the third pipe 260. Figure 15 As shown by the upward arrow in the third pipe 260. After the heating structure 270 heats the cold water in the pot into hot water, the hot water reaches the nozzle 210 through the fourth pipe 280. Figure 15 As shown by the upward arrow in the fourth pipe 280. If the main assembly 200 is in a handheld state, the steam sprayed by the nozzle 210 is sprayed from the nozzle 400. If the main assembly 200 is in a floor mopping state, the steam sprayed by the nozzle 210 is sprayed from the floor mopping assembly 300.

[0163] According to some optional embodiments, the cleaning device further includes: a mop assembly 300 , the mop assembly 300 including a floor brush and a pipeline communicating with the first pipe 160 , the opening of the pipeline facing the floor brush.

[0164] If the main unit 200 is in the mopping state, the steam sprayed from the nozzle 210 enters the pipeline of the mopping unit 300 and then flows to the mop through the pipeline.

[0165] The mop is used to contact the surface to be cleaned to scrape off dirt on the surface to be cleaned.

[0166] Without limitation, the mop can be a roller brush or a mop cloth.

[0167] like Figures 9 to 13 As shown, according to some optional embodiments, the cleaning device further includes: a hook 101 located on the body frame 110; the main unit assembly 200 further includes: a slot 220 located on the outer shell 201; when the main unit assembly 200 is in a mopping state, the hook 101 is located in the slot 220 to strengthen the connection between the main unit assembly 200 and the body frame 110.

[0168] The snap connection between the slot 220 and the hook 101 can further strengthen the connection between the main assembly 200 and the body frame 110, thereby reducing the shaking of the main assembly relative to the body frame 110 when mopping, and even reducing the phenomenon of the main assembly 200 being separated from the body frame 110.

[0169] like Figure 1 、 Figure 7As shown, the body 100 of the cleaning device of the present embodiment further includes a handle 180, a trigger 500, and a handheld switch 206. The trigger 500 is connected to the handle 180, and the handheld switch 206 is connected to the main assembly 200. The handle 180 is mounted on the body frame 110. The trigger 500 and the handheld switch 206 are both used to control the power on or off of the main assembly 200. When the main assembly 200 is powered on, the main assembly 200 starts working, and the nozzle 400 can spray atomized liquid. When the main assembly 200 is powered off, the main assembly 200 stops working, and the nozzle 400 cannot spray atomized liquid.

[0170] The trigger 500 is used to power on or off the main unit assembly 200 in the mopping state, and the handheld switch 206 is used to power on or off the main unit assembly 200 in the handheld state.

[0171] like Figure 1 As shown, in some embodiments, the water tank 240 includes a cover body 202, the outer shell 201 has a accommodating cavity with an opening on one side, the accommodating cavity is used to accommodate the cleaning liquid, and the cover body 202 covers the opening; the main body component 200 also includes: a water tank button 600, the water tank button 600 is connected to the cover body 202, and is at least used to open the cover body 202 to reveal the opening for adding liquid.

[0172] like Figure 1 、 Figure 14 As shown, in some embodiments, the main unit assembly 200 further includes a flow adjustment button 203, which is connected to the outlet of the water tank 240, or the flow adjustment switch is connected to the second pipe 250. The flow adjustment button 203 is used to adjust the water flow out of the water tank 240. Generally, the flow adjustment button 203 can be used in the mopping state and is not used in the handheld state.

[0174] It should be understood that the above embodiments are exemplary and are not intended to include all possible implementations included in the claims. Various modifications and changes can be made to the above embodiments without departing from the scope of the present disclosure. Similarly, the various technical features of the above embodiments can be arbitrarily combined to form other embodiments of the present disclosure that may not be explicitly described.
