[0081] In the present disclosure, unless otherwise clearly defined, the terms "install", "connect", "connect", "fix", "set", etc. 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 mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal connection of two elements or the interaction relationship between two elements.

[0083] Take a steam mop as an example of cleaning equipment. The main unit of the steam mop is detachably mounted on the body. It is laborious to assemble the main unit and the body. Moreover, since the assembly of the main unit and the body involves the steam nozzle and nozzle interface, frequent disassembly and assembly will wear the sealing ring on the nozzle over a long period of use.

[0084] The cleaning device of the disclosed embodiment 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, the embodiment of the present disclosure provides a cleaning device, which includes: a fuselage frame 110, a cover plate 130 and a first pipe 160. The cover plate 130 includes a first part 134 installed on the fuselage frame 110, and a second part 133 connected to the first part 134; the first pipe 160 is installed on the fuselage frame 110, and the first pipe 160 includes a first mounting position 142 and an interface 141, and 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 part 133, and a floating gap 170 is formed between the first mounting position 142 and the second part 133.

[0086] In the disclosed embodiment, there is a floating gap 170 between the first mounting position 142 and the second portion 133, and the first pipe 160 can be shaken by utilizing the floating gap 170. When the component to be assembled with the nozzle 210 installed is assembled with the first pipe 160, the first pipe 160 can be shaken to better adapt to the alignment operation of the component to be assembled at the assembly joint, so that the nozzle 210 can be inserted into the interface 141 more quickly, reducing the number of alignments of the nozzle 210 toward the interface 141, and reducing 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 a floating amount in 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 spray head 210 can be integrated with the water tank 240 as a part of the main assembly 200. Figure 1 As shown, the host assembly 200 can be used as a component to be assembled. When the host 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 installation 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 installation position 142 is adjacent to the assembly joint, so that the first pipe 160 can be better shaken at the interface 141, making it easier to assemble the main assembly 200 and the fuselage 100.

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

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

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

[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 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 pipeline 160 includes: a pipeline 150 and a joint 140; wherein the pipeline 150 is installed on the fuselage frame 110, the joint 140 is connected to the pipeline 150, the joint 140 has an interface 141, the interface 141 is connected to the pipeline 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 installation position 142 is located at the joint 140, which can ensure that the first installation 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 it easier to assemble the main assembly 200 and the fuselage 100.

[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 fix the cover plate 130 to the fuselage frame 110. The avoidance hole 1321 of the connecting portion 132 can expose the interface 141, so as to facilitate 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, and the connecting portion 132 has a protective effect on 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 Fig.10As shown, the location of the nozzle 210 in the main assembly 200 can be made into a recessed area 230, so that the protruding part of the main assembly 200 can be reduced.

[0110] In some usage scenarios, the host assembly 200 needs to be removed from the body 100 to change the usage mode. In this case, the fewer protruding parts on the host assembly 200, the more conducive it is to reduce the bumping phenomenon caused by the host 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 ; 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 exemplarily.

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

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

[0115] When assembling the components to be assembled with the first pipe 160, they are generally assembled from top to bottom. The interface 141 gradually moves toward the fuselage frame 110 from top to bottom. This tilting method makes it easier to assemble the components to be assembled from top to bottom, and is also helpful in reducing the bending of the first pipe 160 during the assembly process, thereby reducing the suffocation of the first pipe 160. In some embodiments, the angle between the interface 141 and the horizontal plane is 20°-40°, and the optimal value is 25°.

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

[0117] like Figure 1 , Figure 7 , Figure 8 and Fig.10As shown, according to some optional embodiments, the cleaning device also includes: a main body component 200, the main body component 200 includes a bracket and a nozzle 210, and the nozzle 210 is installed on the bracket; the main body component 200 has at least a floor mopping state and a handheld state relative to the body frame 110; the main body component 200 is in the floor mopping state, the main body component 200 is installed on the body frame 110, and the nozzle 210 is at least partially located in the interface 141; the main body component 200 is in the handheld state, the main body component 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 working modes. Figure 1 , Figure 8 and Fig.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 state is more suitable for cleaning a larger surface to be cleaned. The handheld state is more portable and can be used to clean a narrow surface to be cleaned. Alternatively, if the nozzle 210 sprays a high-temperature atomized fluid, the handheld state can also be used for ironing clothes. The different states of the host component 200 can meet different usage requirements and help improve the user experience.

[0120] like Fig.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 which gradually tilts downward from the bracket to the fuselage frame 110 can be adapted to the interface 141 which gradually tilts downward from the host assembly 200 to the fuselage frame 110, which is beneficial to reduce the bending of the first pipeline 160 and reduce the air holding problem of the first pipeline 160.

[0123] like Fig.12aAs shown, according to some optional embodiments, the host assembly 200 further has the following relative to the body frame 110: a transition state between the ground-mopping state and the hand-held state; the host assembly 200 is in the transition state, the first end 207 at the bottom of the host assembly 200 contacts the second mounting position 190, there is a gap between the second end 208 at the bottom of the host 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; the host assembly 200 is in the ground-mopping state, and the second end 208 contacts the second mounting position 190. The transition state is also an intermediate process state of the host assembly 200 being installed to the second mounting position 190, or the host assembly 200 being removed from the second mounting position 190.

[0124] The position where the first end 207 at the bottom of the host assembly 200 contacts the second mounting position 190 is the abutment, which is also the fulcrum O for the host assembly 200 to rotate in the first direction when the host assembly 200 changes from the handheld state to the floor mopping state; similarly, the abutment is also the fulcrum O for the host assembly 200 to rotate in the second direction when the host assembly 200 changes from the floor mopping state to the handheld state. The first direction may be a direction toward the cover plate 130 or the body frame 110, and the second direction may be a direction away from the cover plate 130 or the body frame 110, and the second direction is opposite to the first direction.

[0125] The main unit assembly 200 rotates with 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, so that the main unit assembly 200 can be more easily switched between the handheld state and the ground mopping state, and it is also more convenient to assemble the main unit assembly 200 with the body frame 110.

[0126] like Fig.11 , Fig.12a and Fig.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 Fig.11 and Fig.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 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 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 in the length range of the interface 141 on the first axis L2 (it should be noted that: the length range refers to the channel length of the interface 141 used to complete the 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. Fig.12c ), the foot H2 (i.e., the tangent point) of the perpendicular from the fulcrum O to the second axis L1 is located in the length range of the nozzle 210 on the second axis L1 (it should be noted that: the length range refers to the length of the channel of the nozzle 210 for 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 Fig.12c In this way, the nozzle 210 and the interface 141 can be 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 on the first axis L2 is equal to the length B1B2 of the spray head 210 on the second axis L1.

[0130] Exemplarily, when the transition state satisfies the following two conditions, the smoothness of the nozzle 210 and the interface 141 can be guaranteed when the host component 200 changes from the handheld state to the floor mopping state: (1) The rotation trajectory of the host component 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 condition may be satisfied: (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 Fig.11 and Fig.12a The present disclosure also provides a method for using a cleaning device, comprising the following steps:

[0134] S10, the first end 207 of the bottom of the mainframe assembly 200 is brought into contact with the body frame 110;

[0135] S20, with the joint 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] Step S10 and step S20 involve steps in the process of transforming the host assembly 200 from a handheld state to a ground-mopping state, and can also be 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 of the body frame 110 as the fulcrum O, the main assembly 200 is rotated in a direction away from the cover plate 130 located 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 located on the cover plate 130.

[0145] Step S60 involves a step in the process of transforming the host assembly 200 from the ground-mopping state to the handheld state, and can also be used as a step for disassembling the host assembly 200 from the body frame 110 .

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

[0147] Fig.12a The diagram exemplarily shows a partial structural cross-sectional view of the cleaning device when the host assembly 200 is in a transition state.

[0148] Taking the transition state 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, and the second end 208 of the main body assembly 200 is suspended in the air, and then the main body assembly 200 is rotated toward the body frame 110 with the first end 207 as the fulcrum O. Fig.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 Fig.10 , Fig.12a and Fig.13 As shown, according to some optional embodiments, the first end 207 of the host component 200 has adjacent first and second surfaces 205 and 204, and the second mounting position 190 has adjacent third and fourth surfaces 191 and 192; when the host 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 host 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 portion 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 is also separated from the fourth surface 192, and the distal end and the proximal end are opposite ends.

[0151] like Fig.13 As shown, illustratively, the first end 207 at the bottom of the host assembly 200 has a groove, and the first surface 205 and the second surface 204 can be two adjacent inner surfaces of the groove. The second mounting position 190 has a protrusion, and the third surface 191 and the fourth surface 192 are two adjacent surfaces of the protrusion. When the first end 207 at the bottom of the host assembly 200 abuts against the second mounting position 190, the protrusion is located in the groove, and a fulcrum O is formed on the protrusion. This method can ensure the stability of the host assembly 200 and the second mounting position 190 at the abutment in the transition state.

[0152] Without limitation, the second mounting position 190 is a mounting slot. Fig.11 As shown, the host 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 against the third surface 191 can be used as a rotation 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 can reduce the shaking of the main unit assembly 200 in the second mounting position 190 in the mopping state, and further strengthen 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 Fig.12aAs shown, the main engine component 200 uses the point where the far end of the first surface 205 away from the second surface 204 and the abutment with the third surface 191 as the rotation point, and moves tangentially toward the body 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 engine component 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 nozzle head 210 so that the atomized liquid sprayed by the nozzle head 210 is sprayed through the nozzle 400, and the nozzle 400 can be used to achieve the function of cleaning or ironing. Therefore, the nozzle 400 is an accessory, and after the main unit assembly 200 is removed from the body frame 110, it is used to be installed on the main unit assembly 200 for use.

[0157] In some embodiments, 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 method can reduce the impact of the nozzle 400 on the main body assembly 200 and make more reasonable use of the space of the body 100.

Fig.14As shown by the downward arrow in the second pipe 250, the water reaches the third pipe 260 through the water pump outlet, and then enters the pot body through the third pipe 260. Fig.15 As shown by the upward arrow in the third pipe 260. After the heating structure 270 heats the cold water in the pot body into hot water, the hot water reaches the nozzle 210 through the fourth pipe 280, as shown in FIG. Fig.15 As shown by the upward arrow in the fourth pipe 280. If the host assembly 200 is in a handheld state, the steam sprayed by the spray head 210 is sprayed from the nozzle 400.

[0164] If the host assembly 200 is in a mopping state, the steam sprayed from the nozzle 210 enters the pipeline of the mopping assembly 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 the dirt on the surface to be cleaned.

[0168] By utilizing the snap connection between the card slot 220 and the card hook 101, the connection between the main body assembly 200 and the body frame 110 can be further strengthened, thereby reducing the shaking of the main body assembly relative to the body frame 110 when mopping on the ground, and even reducing the phenomenon of the main body assembly 200 being separated from the body frame 110.

When the main assembly 200 is powered on, the main assembly 200 starts to work, 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.
