Description

TECHNICAL FIELD

[0001] The utility model relates to cleaning technical field, especially a kind of cleaning equipment. BACKGROUND

[0002] The cleaning equipment includes a floor brush structure, a machine body and a water tank. The water tank is usually installed on the machine body. The water tank includes a clean water tank and a sewage tank. The clean water tank can provide cleaning liquid to the roller brush of the floor brush structure to wet the roller brush, thereby achieving wet cleaning of the surface to be cleaned. Under the action of negative pressure, the dirt after cleaning is sucked into the sewage tank for temporary storage.

[0003] Taking a scrubber as an example, in order to reduce the weight of the machine body and improve the operation experience, some scrubbers arrange the sewage tank on the floor brush structure. As a result, the sewage tank located on the floor brush structure is prone to be tilted during the movement of the cleaning equipment forward and backward, and a reliable sewage tank fixing structure is needed to fix it on the floor brush assembly. Moreover, when the sewage tank needs to be tilted to discharge sewage, the user needs to bend down to unlock it before taking it out from the floor brush structure, which affects the use experience. SUMMARY

[0004] In view of the above problems, the present application provides a cleaning equipment that can remove the water tank from the floor brush structure without the user bending down to unlock it, making the disassembly of the water tank more quick and convenient and improving the use experience.

[0005] To achieve the above purpose, the present application provides the following technical solutions:

[0006] The present application provides a cleaning equipment, which comprises:

[0007] a floor brush structure;

[0008] a machine body, which is rotatably connected to the floor brush structure, so that the machine body has at least an upright position and an inclined position relative to the floor brush structure;

[0009] a water tank located on the floor brush structure;

[0010] at least one unlocking structure installed on the floor brush structure;

[0011] under the cooperation of the machine body and the unlocking structure, the unlocking structure and the water tank are unlocked or locked;

[0012] wherein, when the machine body is in the upright position, the unlocking structure is unlocked with the water tank, and the water tank is detachable relative to the floor brush structure; when the machine body is in the inclined position, the unlocking structure is locked with the water tank, and the water tank is fixed on the floor brush structure.

[0013] In the embodiments of the present application, the cooperation of the machine body and the unlocking structure is utilized to realize the locking or unlocking between the unlocking structure and the water tank. When the water tank needs to be disassembled, stop cleaning work, and at almost the same time when the machine body is adjusted to the upright position by applying external force to the machine body, the unlocking structure is unlocked with the water tank, and one operation step realizes two purposes (storing the machine body and releasing the water tank); during the cleaning process, at almost the same time when the machine body is adjusted to the inclined position by applying external force in the opposite direction to the machine body (compared with the direction of the external force applied to the machine body during the process of adjusting the machine body to the upright position), the unlocking structure is locked with the water tank, and one operation step realizes two purposes (inclining the machine body and releasing the water tank). Since the machine body is located above the brush structure, the external force applied to the machine body usually acts on the handle of the machine body, without the need to bend down to operate, and then the unlocking or locking between the water tank and the unlocking structure does not need to be bent down, and the disassembly of the water tank is more quick and convenient.

[0014] For those skilled in the art, it is easy to think of setting a foot pedal to realize the locking or unlocking of the water tank by connecting the foot pedal with the unlocking structure. Although this can realize the unlocking of the water tank without bending down, it needs to increase the foot pedal structure, and at least an additional operation step is needed for the unlocking of the water tank, which is complex in structure and redundant in operation. In comparison, the technical scheme of the present application does not need to set an additional triggering structure such as a foot pedal, and combines the unlocking or locking of the water tank by the unlocking structure into the action of switching the position of the machine body, so that one operation step realizes the switching of the position of the machine body and the unlocking of the water tank, which is simple in structure and operation, and effectively improves the use experience.

[0025] When the body is in the inclined position, the unlocking structure is connected with the groove wall of the groove to hinder the separation of the water tank from the brush structure.

[0026] When the body is in the upright position, the unlocking structure is separated from the groove wall of the groove to allow the separation of the water tank from the brush structure.

[0027] The bottom of the water tank has a downwardly protruding boss, and the groove is located in the boss.

[0028] The top of the brush structure has a limiting groove, the first movable member is at least partially located in the limiting groove, the boss can be inserted into the limiting groove and locked or unlocked with the first movable member.

[0057] Embodiment 1

[0058] The embodiment of the present application provides a cleaning device, which comprises a floor brush structure 110, a machine body 130 and a water tank 101 as shown in Figure 1 and Figure 4 The machine body 130 is rotatably connected to the floor brush structure 110, so that the machine body 130 has at least an upright position and an inclined position relative to the floor brush structure 110; the water tank 101 is located on the floor brush structure 110; the unlocking structure 140 is installed on the floor brush structure 110; under the cooperation of the machine body 130 and the unlocking structure 140, the unlocking structure 140 and the water tank are unlocked or locked; wherein, as shown in Figure 2 and Figure 3 When the machine body 130 is in the upright position, the unlocking structure 140 is unlocked with the water tank 101, and the water tank 101 is detachable relative to the floor brush structure 110; as shown in Figure 4 and Figure 5 When the machine body 130 is in the inclined position, the unlocking structure 140 is locked with the water tank 101, and the water tank 101 is fixed on the floor brush structure 110.

[0059] Generally, the cleaning device 100 comprises a clean water tank 150 for providing cleaning liquid for the cleaning part of the floor brush structure 110, and a sewage tank 120 for collecting sewage after cleaning. The water tank 101 located on the floor brush structure 110 can be the clean water tank 150, or the sewage tank 120, or simultaneously include the sewage tank 120 and the clean water tank 150. In the embodiment shown in the present application, as shown in Figure 1 The water tank 101 installed on the floor brush structure 110 is the sewage tank 120, and the clean water tank 150 is installed on the machine body 130.

[0060] The cleaning device 100 needs to adjust the machine body 130 to the inclined position during the cleaning process to facilitate the manual forward and backward dragging of the floor brush structure 110 for cleaning. When the cleaning device 100 stops cleaning, it also needs to adjust the machine body 130 to the upright position for the purpose of reducing the overall machine space occupation, stably placing the overall machine on the ground (for example, the machine body can be vertically placed on the floor brush structure without external force), and the like.

[0061] The application scenarios of stopping cleaning include but are not limited to adding water to the clean water tank 150, dumping sewage from the sewage tank 120, placing the cleaning device 100 on the base station for self-cleaning or charging, and the like in the shutdown or stop state.

[0062] The water tank is detachable from the floor brush structure 110. When the unlocking structure 140 is unlocked from the water tank, the water tank can be removed from the floor brush structure 110 to add water to the water tank or dump sewage. When the unlocking structure 140 is locked with the water tank, the water tank can be stably fixed to the floor brush structure 110 to ensure that the water tank does not tip over or shake during cleaning.

[0063] In the embodiments of the present application, the locking or unlocking between the unlocking structure 140 and the water tank is achieved by the cooperation of the machine body 130 and the unlocking structure 140. For example, the relative position, connection relationship or the force of the machine body 130 on the unlocking structure 140 in the same connection relationship between the machine body 130 and the unlocking structure 140 will change when the machine body 130 is in different positions. By using this change, the locking or unlocking between the unlocking structure 140 and the water tank is achieved.

[0064] When the water tank needs to be detached, the cleaning work is stopped, and at almost the same time when the machine body 130 is adjusted to the upright position by applying an external force to the machine body 130, the unlocking structure 140 is unlocked from the water tank, and one operation step achieves two purposes (vertically placing the machine body 130 and releasing the water tank). During the cleaning process, by applying an external force in the opposite direction to the machine body 130 (compared to the direction of the external force applied to the machine body 130 when adjusting the machine body 130 to the upright position during the stopping process), the machine body 130 is adjusted to the inclined position at almost the same time, and the unlocking structure 140 is locked with the water tank, which is also an operation step to achieve two purposes (inclining the machine body 130 and releasing the water tank). Since the machine body 130 is located above the floor brush structure 110, the external force applied to the machine body 130 is usually applied to the handle on the machine body 130, without the need to bend down to operate, and thus the unlocking or locking between the water tank and the unlocking structure 140 does not need to be bent down, and the detachment of the water tank is more rapid and convenient.

[0065] For those skilled in the art, it is easy to realize the locking or unlocking of the water tank by setting a foot pedal and connecting the foot pedal with the unlocking structure 140. Although this can realize the unlocking of the water tank without bending over, it needs to increase the foot pedal structure and at least an additional operation step for unlocking the water tank, which is complex in structure and redundant in operation. In contrast, the technical scheme of the present application does not need to set an additional triggering structure such as a foot pedal, and combines the unlocking or locking of the water tank by the unlocking structure 140 into the position switching action of the fuselage 130. One operation step realizes the position switching of the fuselage 130 and the unlocking of the water tank, which is simple in structure and operation and effectively improves the use experience.

[0066] Figure 2 In the implementation mode shown, the number of unlocking structures 140 is two, which are symmetrically arranged on the left and right sides of the fuselage 130. It can be understood that the number of unlocking structures 140 can also be one, three or more. The position of the unlocking structure 140 is not limited to Figure 2 As shown, for example: the unlocking structure 140 can also be arranged in front of the fuselage 130.

[0067] In the embodiment of the present application, the upright position of the fuselage 130 can refer to the position where the fuselage 130 is substantially perpendicular to the horizontal plane, and the inclined position refers to the angle between the fuselage 130 and the horizontal plane being smaller than the angle between the upright position and the horizontal plane.

[0068] In some optional embodiments, as shown in Figure 2 and Figure 3 When the fuselage 130 is in the upright position, the fuselage 130 abuts against the unlocking structure 140 and exerts a force on the unlocking structure 140. Under the action of the force exerted by the fuselage 130, the unlocking structure 140 is unlocked from the water tank; as shown in Figure 4 and Figure 5 When the fuselage 130 is in the inclined position, the fuselage 130 is separated from the unlocking structure 140, and the force exerted on the unlocking structure 140 is removed, and the unlocking structure 140 is locked with the water tank.

[0069] As can be seen from Figure 2 and Figure 3 The unlocking structure 140 realizes the locking with the water tank by the front end. The front end of the unlocking structure 140 is away from the water tank after being extruded by the lower front side surface of the fuselage 130 and the rear end of the unlocking structure 140, and the limiting action of the unlocking structure 140 on the water tank disappears. As can be seen from Figure 4 and Figure 5As can be seen, after the body 130 is tilted, the lower front side surface of the body 130 is separated from the rear end of the unlocking structure 140, the force exerted by the body 130 on the unlocking structure 140 is cancelled, and then the front end of the unlocking structure 140 is in contact with the water tank again, and the water tank is limited by the unlocking structure 140 through clamping, insertion or abutting, etc., thereby preventing the separation of the water tank from the brush structure 110.

[0070] The above Figures 2 to 5 The above

[0071] In the implementation not shown in the figures of the embodiments of the present application, the body 130 can be directly or indirectly connected with the unlocking structure 140 at all times.

[0072] In some optional embodiments, when the unlocking structure 140 is locked with the water tank, at least the separation of the water tank from the brush structure 110 upwards is prevented. Figure 5 In the implementation shown in the figures, the unlocking structure 140 has a limiting effect on the upper side and the front side of the water tank. After the unlocking structure 140 is unlocked, the water tank can be lifted relative to the brush structure 110. In this structure, the fixing of the water tank can be further strengthened by means of additional limiting structures (for example, the limiting groove 1101 and the boss 121 cooperation structure described below). In this way, the locking of the water tank by the unlocking structure 140 plays a role in strengthening the fixing, and when the body 130 is in the upright state, the additional limiting structure also plays a role in limiting the water tank, and can ensure the reliability of the water tank placed on the brush structure 110 in the stop cleaning state.

[0073] In the embodiments of the present application not shown in the figures, the unlocking structure 140 can have a limiting effect on the upper side, the front side, the rear side, the left side and the right side of the water tank.

[0074] In some optional embodiments, in combination with the figures shown in Figure 3 , Figure 5 and Figure 7 The unlocking structure 140 includes a first movable member 141 and a first elastic member 142 (the first elastic member 142 is not shown in the figure). Figure 3 The first movable member 141 is movable relative to the brush structure 110; the first elastic member 142 is connected with the first movable member 141 and the brush structure 110 respectively; when the body 130 is in the tilted position, the first movable member 141 is moved to the position locked with the water tank under the elastic force provided by the first elastic member 142.

[0075] In the implementation shown in the figures, the movement of the first movable element 141 relative to the brush structure 110 is linear movement.

[0076] In other implementations, the movement of the first movable element 141 relative to the brush structure 110 can also be curved movement, or a combination of curved movement and linear movement. Alternatively, the movement of the first movable element 141 relative to the brush structure 110 can also be swinging or rotating, or other movement forms, as long as the movement of the first movable element 141 can achieve the locking or unlocking of the water tank.

[0077] The first elastic element 142 is a spring, Figure 7 The first elastic element 142 is shown as a compression spring. When the body 130 is in the upright state, the compression spring is compressed under the action of the body 130; when the body 130 is in the inclined state, the compression is in the relaxed state, and the elastic force released by the compression drives the first movable element 141 to reset to the unlocking position of the water tank.

[0078] In other optional implementations, the first elastic element 142 can also be a spring sheet or other elastic structure.

[0079] In combination with Figure 3 and Figure 5 shown, in some optional embodiments, the first movable element 141 can move in the horizontal direction to lock or unlock the water tank with the first movable element 141.

[0080] Continuing to refer to Figure 3 and Figure 5 shown, the first movable element 141 moves back and forth relative to the brush structure 110 in the horizontal direction, and the switching direction of the body 130 between the upright position and the inclined position is also the front and back direction, so that the two can be better combined.

[0081] Exemplarily, the movement of the first movable element 141 relative to the brush structure 110 can be in the form of sliding. The first movable element 141 achieves the switching of the first movable element 141 between locking and unlocking of the water tank through reciprocating movement within a predetermined range.

[0082] In some optional embodiments, as shown in Figure 3 and Figure 5 , the unlocking structure 140 is located below the water tank. In this way, the unlocking structure 140 can be better hidden, and the position of the water tank cooperating with the unlocking structure 140 can also be hidden at the bottom of the water tank, which can improve the appearance simplicity of the whole machine and improve the use experience.

[0083] In some optional embodiments, in combination with Figure 3 , Figure 5 and Figure 8As shown, when the body 130 is in the upright position, the unlocking structure 140 is located inside the inner cavity of the brush structure 110; when the body 130 is in the inclined position, the unlocking structure 140 is at least partially located outside the inner cavity of the brush structure 110.

[0084] The brush structure 110 includes an inner cavity mainly composed of a shell, which can accommodate the unlocking structure 140. After the body 130 is switched from the inclined position to the upright position, the part of the unlocking structure 140 (specifically the first movable piece 141) located outside the inner cavity can be "pushed" into the inner cavity, so that the unlocking structure 140 is almost entirely located inside the inner cavity. This relative position relationship between the unlocking structure 140 and the brush structure 110 can further improve the simplicity of the whole machine, and is also beneficial to avoid the problem of false triggering caused by excessive setting of the unlocking structure 140 outside.

[0085] In some optional embodiments, as shown in Figure 6 As shown, the bottom 122 of the water tank has a groove 1211, and the unlocking structure 140 is partially inserted into the groove 1211; when the body 130 is in the inclined position, the unlocking structure 140 is connected with the groove wall 1212 of the groove 1211 to hinder the separation of the water tank and the brush structure 110; when the body 130 is in the upright position, the unlocking structure 140 is separated from the groove wall 1212 of the groove 1211 to allow the separation of the water tank and the brush structure 110. In Figure 6 , the bottom of the groove 1211 is open, and the front end of the unlocking structure 140 can be partially inserted into the groove 1211 from the opening, and the locking of the water tank is realized by the clamping, inserting or abutting of the bottom wall of the groove 1211.

[0086] The groove wall 1212 of the groove 1211 cooperates with the unlocking structure 140 to realize the locking or unlocking of the water tank, which is more simple in structure and can minimize the impact on the flatness and appearance of the bottom of the water tank.

[0087] As shown in Figure 3 and Figure 8 In some optional embodiments, the bottom of the water tank has a downwardly protruding boss 121, and the groove 1211 is located in the boss 121; the top of the brush structure 110 has a limiting groove 1101, and the first movable piece 141 is at least partially located in the limiting groove 1101, the boss 121 can be inserted into the limiting groove 1101 and locked or unlocked with the first movable piece 141.

[0088] The contact between the groove wall of the limiting groove 1101 and the outer wall of the boss 121 can realize the limiting effect of the floor brush structure 110 on the water tank. This limiting structure can preliminarily limit the water tank as described in the foregoing additional limiting structure. For example, the cooperation between the limiting groove 1101 and the boss 121 can limit the water tank along the side of the water tank. The water tank is not easy to tilt laterally under the action of static or small external force, but it is easy to disassemble the water tank from above. However, due to the cooperation gap and cooperation height, the water tank is still easy to tilt laterally when subjected to a large external force. The cooperation between the unlocking structure 140 and the groove wall of the water tank bottom groove 1211 improves the reliability of the connection between the water tank and the floor brush structure 110.

[0089] In some optional embodiments, as shown in Figure 7 The floor brush structure 110 includes a floor brush body 111 and a support 112, and the support 112 is mounted on the floor brush body 111. Figure 2 The first movable part 141 includes a horizontal section 1411, a vertical section 1412, and a hook section 1413, and the vertical section 1412 is connected with the horizontal section 1411 and the hook section 1413 respectively. The support 112 includes a track 1121, and the horizontal section 1411 is movably arranged on the track 1121, and the hook section 1413 can be locked or unlocked with the water tank.

[0090] As shown in Figure 5 The hook section 1413 and part of the vertical section 1412 are inserted into the groove 1211 at the bottom of the water tank. The hook section 1413 limits the upward movement of the water tank, and the vertical section 1412 can abut against the front end of the corresponding bottom wall of the groove 1211 to hinder the forward movement of the water tank.

[0091] Without limitation, the first movable part 141 is of an integral structure, for example, the first movable part 141 can be formed by integral molding.

[0092] Figure 7 Exemplarily, the support 112 includes a sliding groove, and the first movable part 141 slides in the sliding groove.

[0093] In some optional embodiments, as shown in Figure 7 The support 112 further includes a first limiting part 1122 and a second limiting part 1123 on the track 1121. The first limiting part 1122 and the second limiting part 1123 are spaced apart, the first limiting part 1122 limits the maximum distance of the forward movement of the first movable part 141, and the second limiting part 1123 limits the maximum distance of the backward movement of the first movable part 141.

[0094] As can be seen from Figure 7 The first limiting part 1122 and the second limiting part 1123 are both formed as vertical walls in the sliding groove.

[0095] The first elastic member 142 is connected to the first movable member 141 at one end and to the support 112 at the other end. In the implementation shown in the drawings of the present application, the first elastic member 142 is fixed at one end to the horizontal section 1411 and at the other end to the rear side of the second limiting portion 1123, and the distance between the front side of the second limiting portion 1123 and the first limiting portion 1122 defines the movable distance of the first movable member 141.

[0096] Embodiment 2

[0097] Embodiment 2 provides a cleaning device. The cleaning device of the present embodiment is different from the cleaning device of Embodiment 1 in that when the body 130 is in the inclined position, the body 130 exerts a force on the unlocking structure 140, and under the action of the force exerted by the body 130, the unlocking structure 140 is locked with the water tank; when the body 130 is in the upright position, the body 130 exerts a force on the unlocking structure, and the unlocking structure 140 is unlocked with the water tank. That is, contrary to Embodiment 1, in Embodiment 2, the body 130 does not exert a force on the unlocking structure 140 when it is in the upright position, but exerts a force on the unlocking structure when it is in the inclined position.

[0098] In some optional embodiments, the unlocking structure 140 comprises a second movable member and a second elastic member. The second movable member is movable relative to the floor brush structure 110; the second elastic member is connected to the second movable member and the floor brush structure 110 respectively; when the body 130 is in the inclined position, the body drives the second elastic member to generate an elastic force to move the second movable member to a position locked with the water tank; when the body 130 is in the upright position, the second elastic member recovers the elastic deformation, and the second movable member moves to a position unlocked with the water tank.

[0099] Exemplarily, the second elastic member can be a tension spring. When cleaning work needs to be performed, the body 130 is inclined, the tension spring is stretched, the tension spring drives the second movable member to move, and the second movable member contacts the locking action of the water tank. When the cleaning work is stopped, the body 130 is upright, the body 130 no longer has a pulling action on the tension spring, the second movable member releases the locking of the water tank, and the water tank can be detached.

[0100] The embodiments or implementations in the present specification are described in a progressive manner, and each embodiment focuses on the difference from other embodiments. The same or similar parts between the embodiments can be mutually referred to.
