[0002] With the development of social productivity, people's living standards have also improved. On the premise that the material foundation is guaranteed, people began to use various tools to reduce labor and improve the quality of life, and cleaning equipment came into being. Among them, floor scrubber products that have both dust and water absorption capabilities have won the favor of a large number of consumers with their powerful floor cleaning capabilities. In recent years, with the updating of technology and the iteration of products, floor cleaning equipment has made great progress. With the improvement of user demand, the demand for cleaning scenes in low positions such as the bottom of sofa beds has become more and more obvious.

[0054] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application and are not used to limit the present application. In the present application, unless otherwise stated, the directional words used, such as "up", "down", "left", and "right", generally refer to the upper, lower, left, and right of the device in actual use or working state, specifically the drawing direction in the accompanying drawings.

[0055] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0056] The present application provides a cleaning device, which is described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of the present application. In the following embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments.

[0057] The embodiment of the present application provides a cleaning device, which may be a handheld vacuum cleaner, a floor scrubber, a carpet cleaning machine, a desktop cleaner, or other cleaning devices, etc., and the present embodiment does not limit them. Figure 1 An embodiment of the present application provides a cleaning device, which includes a body assembly 100 and a cleaning head assembly 300 .

[0058] Please combine Figure 2 and Figure 3 The fuselage assembly 100 includes a fuselage body 110 , a first support wheel 120 and a second support wheel 130 .

[0059] The fuselage body 110 can be used as the structural basis of the cleaning device to connect and carry the remaining components of the cleaning device. For example, the cleaning device can be a floor scrubber, and the fuselage body 110 can be provided with a suction source, a clean water container, a sewage container, and a cleaning head assembly 300, etc., wherein the suction source can be a motor, etc., and the clean water storage container and the sewage storage container can be connected to the cleaning head assembly 300 through a pipeline to respectively realize the functions of providing cleaning liquid to the cleaning head assembly 300 and absorbing sewage.

[0060] Here, the body 110 has a longitudinal direction H, and the body 110 extends longitudinally along the longitudinal direction H. A handle 111 is provided at one end of the body 110. Figure 1 In order to facilitate the user to hold and operate, in the illustrated position, the handle 111 is usually located at the upper end of the body 110, and the cleaning head assembly 300 is located at the lower end of the body 110. The handle 111 may also be provided with operation buttons and display components of the cleaning device, and of course, this embodiment does not constitute an undue limitation thereto.

[0061] See also Figure 3The first support wheel 120 and the second support wheel 130 are spaced apart on the fuselage body 110 along the longitudinal direction H, that is, there is a gap between the first support wheel 120 and the second support wheel 130 in the longitudinal direction H. Figure 2 and Figure 3 In the state shown, the first support wheel 120 and the second support wheel 130 are located on the side of the body 110 close to the surface to be cleaned. Figure 2 and Figure 3 In the state shown, the side of the body 110 close to the surface to be cleaned is the rear side. Usually, the rear side is the side close to the user when the user holds the cleaning device. The user can hold the cleaning device and move forward. Figure 2 In the illustrated direction, the lower side is the side close to the surface to be cleaned, and the first support wheel 120 and the second support wheel 130 are located at the lower side of the fuselage body 110, so that the first support wheel 120 and the second support wheel 130 arranged at intervals can be used to support the fuselage body 110 on the surface to be cleaned. Figure 3 for Figure 2 Bottom view of Figure 3 In the figure, the positional relationship between the first support wheel 120, the second support wheel 130 and the fuselage body 110 can be viewed more clearly.

[0062] Here, the spacing between the first support wheel 120 and the second support wheel 130 in the longitudinal direction H can be set as large as possible to better support the main body 110. For example, along the longitudinal direction H, the first support wheel 120 and the second support wheel 130 can be respectively arranged at the two end positions close to the main body 110, the first support wheel 120 is arranged at the part of the main body 110 close to the cleaning head assembly 300, and the second support wheel 130 is arranged at the part of the main body 110 close to the handle 111. Figure 2 and Figure 3 In the illustrated example, in order to prevent the second support wheel 130 from causing unnecessary obstruction to the user's grip and other operations, the second support wheel 130 is not disposed on the handle portion 111. However, in other embodiments, the second support wheel 130 may also be disposed on the handle portion 111 of the body 110, and the example in this embodiment does not constitute an undue limitation thereto.

[0063] As mentioned above, the cleaning device also includes a cleaning head assembly 300. Here, the cleaning head assembly 300 is rotatably connected to the main body 110. The rotatable connection can be achieved by a rotating shaft, a hinge or other methods, and this embodiment does not constitute an undue restriction on it. In addition, the cleaning head assembly 300 is located at one end of the main body 110 close to the surface to be cleaned. Figure 1Taking the direction shown in the figure as an example, the cleaning head assembly 300 is located at the lower end of the body assembly 100. Figure 2 In order to distinguish the first support wheel 120 from the second support wheel 130, in the embodiment of the present application, the first support wheel 120 is closer to the cleaning head assembly 300 than the second support wheel 130. Here, the first support wheel 120 can be a bull's eye wheel, etc., and of course this embodiment does not constitute an improper limitation thereto.

[0064] Here, the cleaning head assembly 300 mainly includes a cleaning element 310, and the cleaning element 310 is used to clean the surface to be cleaned. In some embodiments, the cleaning head assembly 300 also includes a cleaning head housing 320 and a moving wheel 330. The cleaning head housing 320 has a cleaning cavity, and the cleaning element 310 is arranged on the cleaning head housing 320 and is at least partially located in the cleaning cavity. The moving wheel 330 is arranged on the cleaning head housing 320 to support the cleaning head housing 320. Here, please refer to Figure 1 The cleaning element 310 and the moving wheel 330 can jointly support the cleaning head housing 320. When the cleaning head assembly 300 moves on the surface to be cleaned, rolling friction can be formed between the cleaning element 310 and the moving wheel 330 and the surface to be cleaned.

[0065] In addition, in some embodiments, a cleaning liquid dispensing element such as a water spray plate may be provided in the cleaning chamber. For example, the clean water storage container provided on the fuselage body 110 may be connected to the cleaning liquid dispensing element through a pipeline to supply liquid to the cleaning liquid dispensing element, or the fuselage body 110 may not be provided with a clean water storage container, and the cleaning liquid dispensing element may be supplied with liquid through an external water source, etc., and the examples of this embodiment do not constitute an undue limitation thereto.

[0066] Here, in the embodiment of the present application, the cleaning device has a second state and a first state, and the body assembly 100 can rotate relative to the cleaning head assembly 300 to switch the cleaning device between the first state and the second state.

[0067] See also Figure 1In the illustrated state, the cleaning device is in the second state, the cleaning head assembly 300 is located at the bottom of the body assembly 100 in the illustrated orientation, and the cleaning element 310 and the moving wheel 330 of the cleaning head assembly 300 are arranged in contact with the ground. At this time, the body body 110 and the cleaning head assembly 300 are arranged at an angle. For example, the angle between the body body 110 and the cleaning head assembly 300 can be in the range of [90°, 180°). For example, when the body body 110 and the cleaning head assembly 300 are arranged at an angle of 90°, the body body 110 is approximately in a state perpendicular to the surface to be cleaned, and the longitudinal direction H of the body body 110 is approximately the vertical direction. Here, the longitudinal direction H of the body body 110 is arranged at a second angle with the surface to be cleaned, and the second angle is a right angle. Of course, in other embodiments, the second angle can also be an acute angle, etc., and of course, this embodiment does not constitute an undue limitation thereto.

[0068] See also Figure 2 In the illustrated state, the cleaning device is in the first state, where, compared to Figure 1 In the state shown, the body 110 rotates in a clockwise direction relative to the cleaning head assembly 300 until it is roughly in contact with the surface to be cleaned. During this process, the first support wheel 120 and the second support wheel 130 contact the surface to be cleaned and lift the cleaning head shell 320 and the moving wheel 330.

[0069] At this time, the angle between the main body 110 and the cleaning head assembly 300 on the side close to the surface to be cleaned is approximately 180° or can be greater than 180°, and the longitudinal direction H of the main body 110 can be approximately parallel to the horizontal direction, so as to facilitate the user to better operate the cleaning device and clean low areas. That is, at this time, the main body 110 is set at a first angle to the surface to be cleaned, and the first angle is greater than the aforementioned second angle, and the first angle is greater than or equal to 0°, and it is preferably an angle close to or equal to 0°. Among them, in the embodiment of the present application, the significant difference between the second state and the first state is that in the second state, please see Figure 1 , the cleaning element 310 and the moving wheel 330 are in contact with the surface to be cleaned to jointly support the cleaning head assembly 300. In the first state, see Figure 2 , the first supporting wheel 120, the second supporting wheel 130 and the cleaning element 310 are in contact with the surface to be cleaned to jointly support the cleaning device, and the moving wheel 330 is no longer in contact with the surface to be cleaned.

[0070] For example, in the first state, there is a gap between the cleaning head housing 320 and the moving wheel 330 and the surface to be cleaned, so as to avoid contact with the surface to be cleaned. Figure 4 , Figure 4In order to facilitate the illustration of the lowest point of each component, a portion of the fuselage body 110 in the longitudinal direction H is omitted. Figure 4 In the illustrated direction, the lower side is the direction close to the surface to be cleaned, the lowest point of the cleaning element 310 intersects with a plane α, the lowest point of the cleaning head housing 320 intersects with a plane β, the lowest point of the moving wheel 330 intersects with a plane γ, the lowest point of the first supporting wheel 120 intersects with a plane θ, and the lowest point of the second supporting wheel 130 intersects with a plane δ. Here, plane α is closer to the surface to be cleaned than plane β and plane γ, that is, plane α is located below plane β and plane γ; plane δ is closer to the surface to be cleaned than plane β and plane γ, that is, plane δ is located below plane β and plane γ; plane θ is closer to the surface to be cleaned than plane β and plane γ, that is, plane θ is located below plane β and plane γ; plane δ is closer to the surface to be cleaned than plane β and plane γ, that is, plane δ is located below plane β and plane γ.

[0071] Here, it is understandable that Figure 4 In the state shown, the cleaning device has not changed to the second state in which it is completely in contact with the surface to be cleaned. In the idealized second state, plane θ and plane δ coincide with each other. Exemplarily, the first support wheel 120 and the second support wheel 130 are jointly supported on the surface to be cleaned, and plane θ and plane δ are located at the same vertical height and coincide with the surface to be cleaned. Here, since the cleaning element 310 is a roller brush, etc., its surface is flexible bristles. Therefore, when the cleaning element 310 contacts the surface to be cleaned, the cleaning element 310 will slightly sink to one side of the surface to be cleaned, that is, plane α will generally be slightly lower than plane θ and plane δ. Of course, the examples in this embodiment do not constitute an undue limitation to the present application.

[0072] Here, a general support wheel has only one degree of freedom in one direction, that is, it can only move in a given direction, which will limit the moving direction of the cleaning device, thereby making the use of the cleaning device inconvenient. To this end, in an embodiment of the present application, the first support wheel 120 and the second support wheel 130 have degrees of freedom in at least two directions, that is, the first support wheel 120 and the second support wheel 130 can move in at least two directions on the contact surface, for example, they can have degrees of freedom in two directions perpendicular to each other in a horizontal plane (of course, the example of this embodiment does not constitute an undue limitation to it), so that under the support of the first support wheel 120 and the second support wheel 130, the cleaning device can move in at least two directions.

[0073] For example, the first support wheel 120 can move in the front-to-back direction and the left-to-right direction, so that when the user operates the cleaning device to move, in addition to moving it forward and backward, the user can also pull the cleaning device to move horizontally to achieve a better cleaning effect. Similarly, the second support wheel 130 can also be configured to move in the front-to-back direction and the left-to-right direction, so that the movement resistance of the body 110 can be reduced and the movement can be smoother while achieving good support for the body 110.

[0074] In some embodiments, one or both of the first support wheel 120 and the second support wheel 130 may be universal wheels, so that the first support wheel 120 and the second support wheel 130 have freedom in multiple directions on the surface to be cleaned, and thus the movement direction of the first support wheel 120 and the second support wheel 130 is not restricted. Among them, the universal wheel can be a wheel body that can move in multiple directions, such as a Furley wheel, a Mecanum wheel, a bull's eye wheel, etc. For example, the first support wheel 120 can be a bull's eye wheel to achieve a better support effect. Of course, the example in this embodiment does not constitute an undue limitation to the present application. Therefore, when the first support wheel 120 and the second support wheel 130 are universal wheels, in the first state, through the cooperation between the first support wheel 120 and the second support wheel 130 and the surface to be cleaned, the cleaning equipment can move in addition to moving along the surface to be cleaned. Figure 5 In addition to moving forward and backward in the A and B directions, it can also move arbitrarily in both directions of A and B, such as along Figure 5 The cleaning device can move in the C direction and the D direction in the first state. Furthermore, in the first state, the user can operate the cleaning device to clean low areas such as the bottom of the bed better, more comprehensively and more conveniently. The above arrangement enables the cleaning device to be better controlled, and the movement of the cleaning device is more flexible and light, which helps to improve the efficiency of the cleaning device in cleaning the surface to be cleaned in the first state, and also helps to improve the user experience.

[0075] In some embodiments, the number of the first support wheel 120 and / or the second support wheel 130 can be set to two. For example, two left and right second support wheels 130 are arranged along a direction perpendicular to the longitudinal direction H. In the first state, the two second support wheels 130 and the first support wheel 120 are supported on the surface to be cleaned together. This is because the cleaning device is moved along the longitudinal direction H. Figure 5 When the body assembly 100 rotates in the directions C and D shown, it is possible that the body assembly 100 twists left and right, and since two left and right second support wheels 130 are provided, the left and right sides of the body assembly 100 will not rub against the surface to be cleaned when twisting. Of course, it is understandable that in other embodiments, the number of the first support wheels 120 and / or the second support wheels 130 can also be set to other numbers, and the example in this embodiment does not constitute an undue limitation to the present application.

[0076] In some embodiments, see Figure 2 , a liquid storage container 500 may also be provided on the main body 110 of the cleaning device. Here, in the illustrated orientation, the liquid storage container 500 is located on the upper side of the main body 110, while in other embodiments, the liquid storage container 500 may also be located on the lower side of the main body 110. The example in this embodiment does not constitute an undue restriction on it. Exemplarily, the liquid storage container 500 may be detachably connected to the main body 110 by means of magnetic attraction, snap fit, etc. Of course, in other embodiments, the liquid storage container 500 may also be matched with the main body 110 or fixedly set on the main body 110 by other means. Here, the liquid storage container 500 may be used as the aforementioned clean water storage container, etc., or the liquid storage container 500 may also be used to achieve other purposes in other embodiments, and this embodiment does not constitute an undue restriction on it.

[0077] In the structure known to the inventor of the present application, the liquid storage container 500 has a water outlet, which is usually located at the bottom of the liquid storage container 500. A top-opening water valve needs to be set at the water outlet. However, the top-opening water valve has a large structure and a high height. When the cleaning device is in the first state, the liquid at the bottom of the liquid storage container 500 cannot enter the top-opening water valve, which leads to the problem of a lot of residual liquid in the liquid storage container 500 after use. In addition, since the top-opening water valve is high in the longitudinal direction H, when a water treatment module is set in the liquid storage container 500, the distance between the water treatment module and the bottom of the liquid storage container 500 is also large, resulting in poor treatment effect on the bottom liquid. In addition, since the top-opening water valve and the water outlet are set at the bottom of the liquid storage container 500, liquid leakage is prone to occur when the top-opening water valve and the water outlet are disassembled.

[0078] Different from the aforementioned structure known to the inventor of the present application, in the embodiments of the present application, please refer to Figure 6 Here, the liquid storage container 500 also has a longitudinal direction, and its longitudinal direction is generally parallel to the aforementioned longitudinal direction H. The liquid storage container 500 has a liquid storage space 510, and a water inlet shell 520 is also arranged in the liquid storage space 510. The water inlet shell 520 has a water inlet chamber 521. Figure 6 In the illustrated direction, the water inlet chamber 521 is provided with an opening 522 on the right inner wall, and the opening 522 can be used as a water inlet to connect the water inlet chamber 521 and the liquid storage space 510, and the liquid in the liquid storage space 510 can enter the water inlet chamber 521 through the opening 522. Here, the opening 522 can completely cover the right inner wall of the water inlet chamber 521, that is, the right inner wall of the water inlet shell 520 is completely removed, so that the cross-sectional area of ​​the water inlet end face of the water inlet is larger. Of course, in other embodiments, the opening 522 can only cover a part of the right inner wall of the water inlet chamber 521, and this embodiment does not constitute a limitation thereto.

[0079] Here, please continue to read Figure 6 The opening 522 (i.e., the water inlet) of the water inlet chamber 521 faces the right inner wall of the liquid storage container 500, and there is a water inlet gap L between the opening 522 and the right inner wall of the liquid storage container 500 (see Figure 7 ), that is, the right inner side of the liquid storage container 500 does not fit the water inlet end surface of the opening 522, so as not to hinder the flow of liquid between the water inlet chamber 521 and the liquid storage space 510.

[0080] Here, in the second state, the water inlet shell 520 and its opening 522 can be arranged near the bottom of the liquid storage space 510, so that when the liquid level in the liquid storage container 500 is low, the liquid can still flow into the water inlet chamber 521. Similarly, in the first state, the water inlet shell 520 and its opening 522 can also be arranged near the bottom of the liquid storage space 510, that is, the water inlet gap L should not be arranged too large, so as to avoid that in the first state, the liquid at the bottom is difficult to enter the water inlet chamber 521, for example, the water inlet gap L can be arranged to be less than 10 mm, and of course, this embodiment does not constitute an undue limitation thereto.

[0081] For example, in Figure 6 In the illustrated direction, the lower side is the side with a lower vertical height in the second state. In the second state, the lower side is the side close to the ground waiting to be cleaned; the right side is the side with a lower vertical height in the first state. In the first state, the right side is the side close to the ground waiting to be cleaned. The water inlet housing 520 is arranged close to the right side, and the opening 522 faces the right side. That is, in Figure 6 In the illustrated embodiment, the water inlet housing 520 is disposed near the lower side and the right side, so that the liquid in the liquid storage container 500 can more fully move into the water inlet chamber 521 in both the second state and the first state.

[0082] Here, in the embodiment of the present application, it is defined that in the first state, the side of the liquid storage container 500 close to the surface to be cleaned is the first side, the water inlet shell 520 is arranged close to the first side, and the opening 522 can be arranged toward the first side. Figure 6 In the illustrated direction, the first side is the right side. However, it is understandable that when the illustrated direction changes, the position of the first side may change accordingly; or, in other embodiments, the opening 522 may not be facing the first side, and the example in this embodiment does not constitute an improper limitation thereto.

[0083] Here, in some embodiments, the water inlet housing 520 can be roughly set to be flat, so that the size of the water inlet housing 520 in the longitudinal direction H is small, and thus will not affect the arrangement position of other components. Exemplarily, in the embodiments of the present application, a first direction is also defined, and the first direction is perpendicular to the longitudinal direction H, for example, Figure 8 As an example, it shows the Figure 6 A plan view of the present invention (for ease of reference, the figure does not show the components that block the water inlet housing 520 in the top view direction), the first direction is parallel to any direction of the current plane, for example Figure 8 The left and right directions and the up and down directions in the image. Figure 8 The size of the water inlet housing 520 in the longitudinal direction H (please refer to Figure 6 ) is smaller than the dimension of the water inlet shell 520 in the first direction, that is, the thickness of the water inlet shell 520 is smaller than the dimension of the water inlet shell 520 in the first direction. Figure 8 The length in the left and right directions is also smaller than the length in the water inlet shell 520. Figure 8 The length in the up and down directions.

[0084] Exemplarily, the cleaning equipment may also include a water treatment device (not shown). Figure 6 The water treatment device is disposed in the liquid storage space 510 and is located on the side of the water inlet housing 520 away from the cleaning head assembly 300 (i.e. Figure 6 Here, since the water inlet shell 520 is generally flat, the water treatment device is closer to the cleaning head assembly 300, that is, closer to the bottom of the liquid storage space 510 in the second state, so that the liquid in the liquid storage space 510 can be better treated. For example, the water treatment device can be an electrolysis device, and the electrolysis device can include a first electrode and a second electrode. The first electrode and the second electrode are used to electrolyze the liquid in the liquid storage space 510 to form active oxygen water with a sterilization function, and hydroxyl radicals are generated through hydrogen ions and hydroxide ions in the active oxygen water, and the strong oxidizing ability of the hydroxyl radicals plays a sterilizing role.

[0085] In further embodiments, please refer to Figure 6 In addition to the water inlet chamber 521 and the water inlet, the liquid storage container 500 is also provided with a water outlet 531, which is connected to the water inlet chamber 521. For example, the water outlet 531 is connected to the water inlet chamber 521 through a hose or a hard pipe. Here, a water outlet joint 530 is provided on one side of the top of the liquid storage container 500, and the water outlet joint 530 has the water outlet 531. Of course, in other embodiments, the formation method of the water outlet 531 is not limited to this, and the water outlet 531 can also be formed by opening a hole on the wall surface of the liquid storage container 500 or by other methods. In addition, the position of the water outlet 531 is not limited to this, as long as the water outlet 531 is not located at the bottom of the liquid storage space 510, the example in this embodiment does not constitute an improper limitation to it.

[0086] It can be seen that, through the coordinated arrangement of the water inlet chamber 521 and the water outlet 531, the liquid in the liquid storage container 500 can enter the water inlet chamber 521 through the water inlet (i.e., the opening 522) of the water inlet chamber 521, and then flow to the water outlet 531 through the pipeline. In the second state and the first state, the water inlet of the water inlet chamber 521 is located near the bottom of the liquid storage container 500, and the liquid can enter more fully and flow from the water inlet to the water outlet 531, which helps to reduce the residual water in the liquid storage container 500.

[0087] Furthermore, when the water inlet chamber 521 is configured as a flat structure, the water treatment module of the cleaning equipment can be disposed closer to the bottom of the liquid storage space 510, so that the liquid in the liquid storage container 500 can be processed more efficiently.

[0088] In addition, by means of the coordinated arrangement of the water inlet chamber 521 and the water outlet 531, the water outlet 531 may not be arranged at the bottom of the liquid storage container 500, so that liquid leakage is less likely to occur when the components at the water outlet 531 are disassembled and assembled.

[0089] In addition to the above structure, the liquid storage container 500 may also be provided with an openable upper cover to open and close the liquid storage space 510. The liquid storage space 510 may also be provided with an openable water injection port to inject or discharge liquid. The top of the liquid storage space 510 may also be provided with a vent hole 560, etc., to balance the pressure in the liquid storage space 510 during use. The examples in this embodiment do not constitute an improper limitation on the structure of the liquid storage container 500.

[0090] Here, in some embodiments, the fuselage body 110 is further provided with a docking portion 112, see Fig. 9 The docking portion 112 has a docking port 1121 and a liquid passage 1122 connected to the docking port 1121. Exemplarily, the liquid passage 1122 includes two straight sections arranged at an angle to change the flow direction of the liquid, and the liquid passage 1122 can be connected to the cleaning chamber of the cleaning head assembly 300 through a pipeline or the like.

[0091] The water outlet connector 530 and the water outlet 531 of the cleaning device are used to dock with the docking portion 112 and the docking port 1121, so that the liquid storage container 500 can be connected to the cleaning head assembly 300. A driving member such as a pump can be configured in the pipeline between the liquid storage container 500 and the cleaning head assembly 300 to drive the liquid to flow.

[0092] Here, as mentioned above, the liquid storage container 500 can be installed on the fuselage body 110 in a detachable manner. During installation, generally, the liquid storage container 500 will rotate relative to the fuselage body 110, for example, the liquid storage container 500 needs to rotate relative to the fuselage body 110 to move to a position of mutual cooperation (such as snap-fit ​​cooperation, etc.). Alternatively, there is a certain deflection angle between the liquid storage container 500 and the fuselage body 110. For example, due to the limitation of processing accuracy or assembly error, there is a certain deflection between the actual assembly position of the liquid storage container 500 after being installed on the fuselage body 110 and the preset assembly position. In the above case, the fixed docking portion 112 and the docking port 1121 may not be accurately docked with the water outlet joint 530 and the water outlet 531 of the liquid storage container 500 during or after assembly, thereby causing leakage.

[0093] To this end, in the embodiment of the present application, the docking portion 112 is rotatably connected to the fuselage body 110, and an elastic member 113 is provided between the docking portion 112 and the fuselage body 110, and the elastic member 113 is used to apply a force to the docking portion 112 pointing away from the fuselage body 110 and close to the liquid storage container 500, so that when the docking portion 112 and the water outlet connector 530 are matched, the docking portion 112 can be better matched and docked with the water outlet connector 530 under the action of the elastic member 113. Here, the elastic member 113 can be a spring, a retaining spring, etc.

[0094] For example, see Fig.10 In some embodiments, the fuselage body 110 (see Figure 2 ) includes a fixing frame 114, which can be assembled on the fuselage body 110 or can be integrally formed with the fuselage body 110, and the examples of this embodiment do not constitute an undue limitation to it. Here, a protruding first connecting portion 1141 is provided on the fixing frame 114 in the direction close to the liquid storage container 500, and the docking portion 112 corresponds to the first connecting portion 1141 and is provided with a second connecting portion 1123 protruding in the direction close to the fixing frame 114. The elastic member 113 is a spring in this embodiment, and the spring is sleeved on the first connecting portion 1141 and the second connecting portion 1123 to be limited. In this way, an elastic connection between the fixing frame 114 and the docking portion 112 is achieved, and the docking portion 112 can rotate relative to the fixing frame 114 and the fuselage body 110.

[0095] Furthermore, in order to limit the rotation range of the docking portion 112, a limiting protrusion 1124 is provided on the docking portion 112 on a side close to the fixing frame 114 and the fuselage body 110, and the limiting protrusion 1124 protrudes in a direction close to the fixing frame 114 and the fuselage body 110. Here, corresponding to the limiting protrusion 1124, a stopper 1142 may also be provided on the fixing frame 114, and the stopper 1142 protrudes from the fixing frame 114 in a direction close to the docking portion 112. Fig. 9 and Fig.10 In the illustrated direction, when the water outlet connector 530 contacts the docking portion 112 and drives the docking portion 112 to rotate a certain distance in the clockwise direction, the limiting protrusion 1124 contacts the stop portion 1142 and forms a stop, thereby limiting the rotation angle of the docking portion 112.

[0096] In addition, in order to improve the sealing performance between the docking portion 112 and the water outlet joint 530, the cleaning device may further include a sealing member 115. The material of the sealing member 115 may be soft rubber, etc., which is not limited in this embodiment. At least a portion of the sealing member 115 is sealed and connected between the docking portion 112 and the water outlet joint 530. Fig.10 The inner diameter of the outlet end face of the water outlet joint 530 is larger than the inner diameter of the inlet end face of the docking part 112, a part of the docking part 112 is fitted on the radial inner side of the water outlet joint 530, a part of the sealing member 115 is sleeved on the docking part 112 and is located between the water outlet joint 530 and the docking part 112 in the radial direction, and the sealing member 115 is provided with a plurality of protrusions in the radial direction toward the water outlet joint 530, and the plurality of protrusions are embedded between the water outlet joint 530 and the docking part 112 to form a good sealing connection.

[0097] In the above embodiment, the docking portion 112 is rotatably provided on the fuselage main body 110 as an example for explanation, but it can be understood that in other embodiments, the water outlet joint 530 can also be rotatably provided on the liquid storage container 500, which can also achieve similar effects. The rotatable connection between the water outlet joint 530 and the liquid storage container 500 is roughly the same as the structure of the rotatable connection between the docking portion 112 and the fuselage main body 110 mentioned above. For example, the water outlet joint 530 is connected to the liquid storage container 500 through an elastic member, and a limiting protrusion and a stopper can be correspondingly provided between the water outlet joint 530 and the liquid storage container 500 to achieve the limitation of the rotation angle. Under the example of the above embodiment, those skilled in the art can know the specific setting of the relevant structure, and this embodiment will not be described in detail.

[0098] In some embodiments, see Fig.11The liquid storage container 500 is mounted on the main body 110 of the cleaning device. Here, the liquid storage container 500 has a connection port 540. The connection port 540 is used to connect with the main body 110 to form a fluid connection with the main body 110. Fig.11 In the embodiment, the connection port 540 is an inlet for the fluid to enter the liquid storage space of the liquid storage container 500 from the body 110. Of course, it can be understood that in other embodiments, the connection port 540 can also be an inlet for the fluid to enter the body 110 from the liquid storage container 500, and the example in this embodiment does not constitute an improper limitation thereto.

[0099] Here, the liquid storage container 500 is detachably mounted on the body 110. When the liquid storage container 500 is removed and installed, residual liquid flowing out of the body 110 or the liquid storage container 500 may be present at the connection port 540 and outside the connection port 540. For this reason, in the embodiments of the present application, please refer to Fig.12 and Fig.13 A pressure source 550 is also provided on the liquid storage container 500, and the pressure source 550 may be an air pump or the like. Fig.12 , the pressure source 550 is connected to the aforementioned connection port 540, for example, the pressure source 550 is connected to the aforementioned connection port 540 through a pipe 551. Thus, through the suction of the pressure source 550, the residual water at the connection port 540 and outside the connection port 540 can be sucked away to improve the user experience. Here, the pressure source 550 can be arranged in the liquid storage space 510, or it can be arranged outside the liquid storage space 510, and this embodiment does not constitute an undue limitation to it. In addition, in some embodiments, one end of the pressure source 550 is connected to the connection port 540 and the other end is connected to the liquid storage space 510, so that the pressure source 550 can also suck the residual water into the liquid storage space 510 for further use or collection.

[0100] In addition, in some embodiments, an electrolysis device is also provided in the liquid storage container 500. When the electrolysis device is in operation, hydrogen is generated. When the hydrogen concentration in the liquid storage container 500 is between 4% and 75%, it is prone to explosion when exposed to open flames, etc. Here, the pressure source 550 also helps to draw gas into the liquid storage space 510 to reduce the hydrogen concentration in the liquid storage container 500.

[0101] Here, in some embodiments, see Fig.12, a vent 560 is also provided on the liquid storage container 500, and the vent 560 is connected to the liquid storage space 510. Here, the vent 560 can be used to inlet air into the liquid storage space 510 so as to balance the pressure in the liquid storage space 510. In addition, the vent 560 can also be used to allow the gas in the liquid storage space 510 to flow outward, for example, to allow hydrogen to volatilize outward, so as to reduce the hydrogen concentration in the liquid storage space 510. That is, the vent 560 can take into account the intake and exhaust requirements of the liquid storage container 500. It can be understood that the vent 560 can be provided at the same time as the aforementioned pressure source 550, so that when the pressure source 550 draws gas into the liquid storage space 510, the gas can be discharged from the vent 560 to balance the pressure in the liquid storage space 510. Of course, in some embodiments, the vent 560 and the pressure source 550 can also be provided separately, and the example in this embodiment does not constitute an undue limitation thereto.

[0102] For example, the vent hole 560 can be arranged on the top of the liquid storage container 500, away from the main body 100. Thus, when the cleaning device is in the first state, the vent hole 560 is located on the upper side of the liquid storage space 510 in the vertical direction; when the cleaning device is in the second state, the vent hole 560 is also located on the upper side of the liquid storage space 510 in the vertical direction. That is, no matter the cleaning device is upright, tilted at a large angle, or lying flat, the vent hole 560 is at a high point in the opposite direction of gravity, and the liquid in the liquid storage container 500 is not easy to leak out through the vent hole 560.

[0103] Accordingly, see Figures 1 to 13 The embodiment of the present application further provides a liquid storage container 500, which can be used to cooperate with a cleaning device, for example, to be connected to the body 110 of the cleaning device to provide liquid for the cleaning device. Accordingly, a cleaning device having the liquid storage container 500 is also provided herein.

[0104] Here, the liquid storage container 500 has a liquid storage space 510, and the liquid storage space 510 has a water inlet chamber 521, and the water inlet chamber 521 has a water inlet, and the water inlet faces the inner wall of the liquid storage container 500, and there is a water inlet gap between the inner wall and the water inlet chamber 521, and the water inlet chamber 521 is connected to the liquid storage space 510 through the water inlet gap. In addition, the liquid storage container 500 is also provided with a water outlet 531, and the water outlet 531 is connected to the water inlet chamber 521.

[0105] The side facing the water inlet is the first side, the inner wall of the liquid storage container 500 facing the water inlet is the inner wall of the liquid storage container 500 located on the first side, and the water inlet chamber 521 is provided with an opening 522 on the wall facing the first side, and the opening 522 is used to form the water inlet.

[0106] Here, the liquid storage container 500 has a longitudinal direction, and when the liquid storage container 500 is assembled to the cleaning device, the longitudinal direction is roughly consistent with the longitudinal direction H of the body 110 of the cleaning device. Here, usually, the water inlet chamber 521 is located at the end of the liquid storage container 500 in the longitudinal direction H. In actual use, the water inlet chamber 521 is located at the lower end of the liquid storage container 500 in the longitudinal direction H. Here, a first direction is also defined, and the first direction is perpendicular to the longitudinal direction. The size of the water inlet chamber 521 in the longitudinal direction is smaller than the size of the water inlet chamber 521 in the first direction, that is, the water inlet chamber 521 is roughly flat.

[0107] In some embodiments, a water treatment device is further disposed in the liquid storage container 500 . The water treatment device is disposed in the liquid storage space 510 and is located on one side of the water inlet chamber 521 , typically, on the upper side of the water inlet chamber 521 .

[0108] Accordingly, see Figures 1 to 10 In order to better achieve the technical effect of the embodiment of the present application, the embodiment of the present application also provides a cleaning device, which has a substantially same structure as the cleaning device in the aforementioned embodiment. For details, please refer to the aforementioned embodiment, and this embodiment will not be described in detail. The difference is that compared with the aforementioned cleaning device embodiment, the cleaning device in this embodiment is not provided with the first support wheel 120 and the second support wheel 130 at the same time.

[0109] Application Example 1

[0110] In application example 1, a liquid storage container 500 is provided, which has a longitudinal direction and a liquid storage space 510 therein, and a water inlet shell 520 is provided at the bottom position of the longitudinal direction, and a water inlet chamber 521 is provided in the water inlet shell 520, and an opening 522 is provided on one side of the water inlet shell 520 to form a water inlet, and the opening 522 faces the inner wall of the liquid storage container 500 and forms a water inlet gap with the inner wall, and the water inlet chamber 521 is connected to the liquid storage space 510 through the water inlet gap. Since the distance between the water inlet and the interior of the liquid storage container 500 to which it faces is very close, that is, the size of the water inlet gap can be set small, when the liquid storage container 500 is applied to a cleaning device in a lying state, the liquid in the liquid storage container 500 can be sucked away as much as possible, which helps to reduce the residual liquid in the liquid storage container 500.

[0111] At the same time, the liquid storage container 500 is also provided with a water outlet 531, which is arranged at one side of the top in the longitudinal direction, and the water outlet 531 and the water inlet shell 520 are connected through a pipeline.

[0112] Application Example 2

[0113] In application example 2, a liquid storage container 500 is provided, which has substantially the same structure as the liquid storage container 500 provided in application example 1. The difference is that the water inlet shell 520 is substantially flat, and an electrolysis device is also provided in the liquid storage container 500. Since the water inlet shell 520 is flat, the length occupied by the water inlet shell 520 in the longitudinal direction is relatively small, and the electrolysis device can be closer to the bottom position of the liquid storage space 510, so that the electrolysis blind area of ​​the electrolysis device is better, and the electrolysis effect will be better.

[0114] Application Example 3

[0115] In application example 3, a cleaning device is provided, which includes a body 110 and a cleaning head assembly 300, and uses the liquid storage container 500 provided in application example 1 or 2. The liquid storage container 500 is detachably mounted on the body 110, and a docking portion 112 is provided on the body 110, and the docking portion 112 is used to dock with the water outlet 531 of the liquid storage container 500 to form liquid communication.

[0116] Application Example 4

[0117] In application example 4, a cleaning device is provided, which has a substantially same structure as the cleaning device provided in application example 3. The difference is that the docking portion 112 is connected to the fuselage body 110 via a spring, so that the docking portion 112 can rotate relative to the fuselage body 110. During the installation of the liquid storage container 500, the water outlet connector 530 and the water outlet 531 on the liquid storage container 500 have an arc-shaped motion trajectory, that is, the water outlet connector 530 and the water outlet 531 will change their angles relative to the fuselage body 110 during the installation process. The rotation design of the docking portion 112 here enables the docking portion 112 to cooperate with the liquid storage container 500 more smoothly during assembly.

[0118] Application Example 5

[0119] In application example 5, a cleaning device is provided, which has a substantially similar structure to the cleaning device provided in application example 4. The difference is that a limiting protrusion 1124 is provided on the side of the docking portion 112 close to the fuselage main body 110, and a stopper 1142 is provided on the fuselage main body 110 corresponding to the limiting protrusion 1124, and the stopper 1142 protrudes in the direction close to the docking portion 112 to limit the rotation angle of the docking portion 112. In the process of assembling the liquid storage container 500 to the fuselage main body 110, the liquid storage container 500 drives the docking portion 112 to rotate until the limiting protrusion 1124 abuts against the stopper 1142, and the docking portion 112 is installed in place.

[0120] Application Example 6

[0121] In application example 6, a cleaning device is provided, which has a structure substantially the same as that of any of the cleaning devices provided in application examples 3 to 5. The difference is that a sealing member 115 is further provided at the connection between the docking portion 112 and the liquid storage container 500, and the sealing member 115 can be made of a soft rubber material, etc., to achieve a sealed connection between the docking portion 112 and the liquid storage container 500.

[0122] Here, the seal 115 is provided with three layers of protrusions, which can achieve a better water leakage prevention effect when in use, and also help to reduce the liquid from flowing out of the docking position during the process of disassembling and assembling the liquid storage container 500 from the fuselage main body 110.

[0123] Application Example 7

[0124] In application example 7, a cleaning device is provided, including a body assembly 100 and a cleaning head assembly 300, wherein the body assembly 100 is rotatably connected to the cleaning head assembly 300. The body assembly 100 includes a body main body 110, a first support wheel 120, and a second support wheel 130. The first support wheel 120 and the second support wheel 130 are arranged at intervals along the longitudinal direction of the body main body 110. The cleaning head assembly 300 includes a cleaning head housing 320, a cleaning element 310, and a moving wheel 330.

[0125] The body assembly 100 can rotate relative to the cleaning head assembly 300 to switch the cleaning device between a first state and a second state. In the first state, the first support wheel 120, the second support wheel 130 and the cleaning element 310 are in contact with the surface to be cleaned to jointly support the cleaning device. At this time, the cleaning head and the moving wheel 330 are not in contact with the surface to be cleaned.

[0126] Application Example 8

[0127] In application example eight, a cleaning device is provided, which is substantially the same in structure as the cleaning device provided in any one of application examples three to six. The difference is that a first support wheel 120 and a second support wheel 130 are also provided on the fuselage body 110. The first support wheel 120 and the second support wheel 130 are arranged at intervals along the longitudinal direction of the fuselage body 110. The cleaning head assembly 300 includes a cleaning head housing 320, a cleaning element 310 and a moving wheel 330.

[0128] The body assembly 100 can rotate relative to the cleaning head assembly 300 to switch the cleaning device between a first state and a second state. In the first state, the first support wheel 120, the second support wheel 130 and the cleaning element 310 are in contact with the surface to be cleaned to jointly support the cleaning device. At this time, the cleaning head and the moving wheel 330 are not in contact with the surface to be cleaned.
