Description

Technical Field

[0001] The invention relates to the technical field of cleaning tools, and in particular to a sewage tank of a cleaning device and a cleaning device. Background Art

[0002] Cleaning equipment commonly used in daily life, such as floor scrubbers, sucks sewage, garbage and other dirt generated during the cleaning process into a sewage tank provided on the cleaning equipment.

[0003] The air sucked in during the process of sucking in dirt needs to be discharged, so an air outlet is provided in the sewage tank. In order to ensure smooth water inflow into the sewage tank, the water inlet pipe in the sewage tank extends to the upper part of the sewage tank. During the process of sewage being sucked into the sewage tank, it is easy for sewage to overflow from the air outlet, and when the cleaning equipment cleans some areas, the cleaning device will be tilted or placed flat, which can easily cause the sewage in the sewage tank to overflow. Sewage overflow will cause secondary pollution to the cleaning area. If sewage overflows and flows into other structures in the cleaning equipment, some parts may be damaged. For example, sewage flowing into the motor of the cleaning device may cause damage to the motor.

[0018] After being connected to the first water baffle plate, the second water baffle plate forms a bend relative to the first water baffle plate and extends toward the side wall of the outlet side of the box body.

[0019] Furthermore, when the box body is in a vertical state, the first water baffle plate and the side wall of the box body enclose a subspace located in the second liquid storage space, and the subspace can accommodate the water outlet end of the water inlet pipe carrying the buoyancy member;

[0020] The radial dimension of the buoyancy member is smaller than the inner diameter of the subspace, and there is a gap between the buoyancy member and the first water retaining plate, and between the buoyancy member and the side wall corresponding to the subspace.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0038] In view of the defects of the prior art, the present invention arranges a buoyancy member at the water outlet end of the water inlet pipe, and the water inlet pipe is bent under the drive of the buoyancy member, and drives the water outlet end of the water inlet pipe to float on the liquid surface, so that when the cleaning equipment works at any working angle, the water outlet end floats on the liquid surface, and the water inlet direction remains perpendicular to the liquid surface, thereby increasing the liquid storage capacity of the sewage tank of the cleaning equipment in an inclined or horizontal state; at the same time, by arranging a water retaining assembly, it is ensured that the liquid in the box body will not flow out from the outlet of the box body, thereby avoiding damage to the motor connected to the outlet due to the entry of liquid, thereby ensuring the working stability of the cleaning equipment and improving the service life of the cleaning equipment.

[0039] See attached Figure 1 to Figure 3 The present embodiment provides a sewage tank for cleaning equipment, comprising: a box body 1 for containing liquid, the box body 1 being provided with an inlet 11 and an outlet 12; a water inlet assembly 2, comprising a water inlet pipe 21 and a buoyancy member 22, the water inlet end of the water inlet pipe 21 being connected to the inlet 11, the buoyancy member 22 being arranged at the water outlet end of the water inlet pipe 21, and being able to make the water outlet end of the water inlet pipe 21 float on the liquid surface; a water retaining assembly 3, which is arranged on a side close to the outlet 12, and when the box body 1 is in an inclined or horizontal state, the water retaining assembly 3 and the box body 1 enclose a first liquid storage space, and the water retaining assembly 3 forms a barrier between the first liquid storage space and the outlet 12.

[0040] It should be noted that: in the present embodiment, by arranging a buoyancy member 22 at the water outlet end of the water inlet pipe 21, the water inlet pipe 21 is bent under the drive of the buoyancy member 22, and drives the water outlet end of the water inlet pipe 21 to float on the liquid surface, so that when the cleaning equipment works at any working angle, the water outlet end floats on the liquid surface, and the water inlet direction remains perpendicular to the liquid surface, thereby increasing the liquid storage capacity of the sewage tank of the cleaning equipment in an inclined or horizontal state; at the same time, by arranging the water retaining assembly 3, it is ensured that the liquid in the box body 1 will not flow out from the outlet of the box body 1, thereby avoiding the motor connected to the outlet 12 from being damaged due to the entry of liquid, thereby ensuring the working stability of the cleaning equipment and improving the service life of the cleaning equipment.

[0041] In this embodiment, the direction from the inlet 11 to the outlet 12 is defined as the height direction of the box body 1 . The inlet 11 is provided at the bottom of the box body 1 , and the outlet 12 is provided at the top of the box body 1 .

[0042] In some possible embodiments, the water inlet pipe 21 is a retractable tubular structure, and the water inlet pipe 21 can be retracted and extended under the drive of the buoyancy member 22 .

[0043] Optionally, the water inlet pipe 21 is a retractable bellows.

[0044] In some possible embodiments, the buoyancy member 22 is detachably connected to the water outlet end of the water inlet pipe 21 to achieve rapid replacement of the buoyancy member 21 .

[0045] Specifically, the buoyancy member 22 is sleeved on the water outlet end of the water inlet pipe 21 and is tightly matched with the water outlet end of the water inlet pipe 21 .

[0046] Furthermore, the buoyancy member 22 is made of solid buoyancy material.

[0047] In some possible embodiments, the water inlet pipe 21 has a water inlet end arranged near the inlet 11; the sewage tank of the cleaning equipment also includes a fixing component 4, a first end of the fixing component 4 is fixedly connected to the box body 1, and a second end of the fixing component 4 is sleeved on the water inlet end so that the water inlet end remains vertical along the direction from the inlet 11 to the outlet 12. By setting the fixing component 4, it is possible to ensure that the water inlet end remains vertical along the direction from the inlet 11 to the outlet 12, thereby avoiding the water inlet pipe 21 being blocked due to excessive bending angle at one end near the inlet 11, thereby ensuring the normal operation of the cleaning equipment and improving the stability of the cleaning equipment.

[0048] In some other possible embodiments, the fixing component 4 is a fixing ring, the fixing component 4 is sleeved on the water inlet pipe 21, and one end of the fixing component 4 is fixedly connected to the box body 1. At this time, the fixing component 4 can ensure that the water inlet pipe 21 will not bend significantly on the side close to the water inlet end under the drive of the buoyancy member 21. At the same time, the structure is simple, easy to install and cost-saving.

[0049] Specifically, the height of the fixing ring is set according to actual conditions, as long as it is ensured that the water inlet end of the water inlet pipe 21 does not bend significantly.

[0050] Furthermore, the fixing ring and the water inlet pipe 21 are matched with each other in a clearance, so that the water inlet pipe 21 is driven by the buoyancy member 22 , and the part of the water inlet pipe 21 sleeved in the fixing ring can also be slightly bent.

[0051] Optionally, the fixing ring is tightly matched with the water inlet pipe 21 , so that the water inlet pipe 21 is driven by the buoyancy member 22 , and the part of the water inlet pipe 21 sleeved in the fixing ring cannot be bent.

[0052] Specifically, the hardness of the fixing ring is much greater than the hardness of the water inlet pipe 21 .

[0053] In some possible embodiments, the fixing assembly 4 includes a slide rail 41 and a fixing member 42 mounted on the water inlet pipe 21; the sliding direction of the slide rail 41 is set along the direction from the inlet 11 to the outlet 12, and the fixing member 42 is slidably connected to the slide rail 41. The structure of the fixing assembly 4 is simple. Only by setting the slide rail 41 and the fixing member 42, the end of the water inlet pipe 21 close to the inlet 11 can be prevented from being blocked due to excessive bending angle at any working angle of the cleaning equipment. At the same time, by setting the slide rail 41, it can be ensured that no matter whether the slide rail 41 is fixedly connected to the water inlet pipe 21 or the slide rail 41 is fixedly connected to the water inlet pipe 21, the side of the water inlet pipe 21 close to the inlet 11 can be guaranteed to work normally.

[0054] In some possible embodiments, the fixing member 42 is a fixing ring, and the slide rail 41 is arranged along the height direction of the box body 1 so that the fixing member 42 moves along the height direction of the box body 1 .

[0055] In some possible embodiments, the fixing member 42 is fixedly connected to the water inlet pipe 21 .

[0056] In some other possible embodiments, the fixing member 42 is slidably connected to the water inlet pipe 21 .

[0057] Specifically, a sliding portion is provided on the fixing member 42 . After the fixing member 42 is sleeved on the air intake pipe 21 , the sliding portion of the fixing member 42 is slidably connected to the slide rail 41 .

[0058] In some possible embodiments, the slide rail 41 is disposed close to the inlet 11 so that the fixing member 42 can ensure that the end of the air inlet pipe 21 close to the inlet 11 will not bend, thereby preventing dirt from clogging the air inlet end of the air inlet pipe 21 .

[0059] In some possible embodiments, the water inlet pipe 21 has a water outlet end arranged away from the inlet 11; when the box body 1 is in a vertical state, the buoyancy member 22 is vertically arranged in cooperation with the water outlet end, and the inner cavity of the box body 1 forms a second liquid storage space. When the box body 1 is in a vertical state, the inner cavity of the box body 1 forms a second liquid storage space, and the buoyancy member 22 is vertically arranged in cooperation with the water outlet end. The formed second liquid storage space can store liquid. At the same time, the water retaining assembly 3 arranged in the second liquid storage space can prevent the liquid in the box body 1 from flowing out of the outlet 12, and prevent the motor connected to the outlet 12 from being damaged due to the entry of liquid, thereby ensuring the working stability of the cleaning equipment and improving the service life of the cleaning equipment.

[0060] In some possible embodiments, the water baffle assembly 3 includes a first water baffle 31 and a second water baffle 32 that are connected; the first water baffle 31 is arranged along the direction from the inlet 11 to the outlet 12, the first end of the first water baffle 31 is close to the side of the outlet 12, and the second end of the first water baffle 31 away from the outlet 12 is fixedly connected to the second water baffle 32; after the second water baffle 32 is connected to the first water baffle 31, a bend relative to the first water baffle 31 is formed, and extends toward the side wall of the outlet side of the box body 1. By extending the second water baffle 32 toward the side wall of the outlet side of the box body 1, the second water baffle 32 can block the liquid regardless of whether the sewage tank is in an inclined or flat state, thereby preventing the liquid from being sucked into the motor of the cleaning equipment and causing damage to the motor, thereby ensuring the working stability of the cleaning equipment and improving the service life of the cleaning equipment.

[0061] In some possible embodiments, the first water baffle 31 is an arc-shaped plate; when the box body 1 is in a vertical state, the first water baffle 31 and the box body 1 form a second liquid storage space, and the second liquid storage space surrounds the buoyancy member 22 to enable the second liquid storage space to oscillate the liquid in the box body 1 and thereby achieve water vapor separation, thereby preventing the liquid from leaving the box body 1 from the outlet 12.

[0062] Optionally, the first water baffle 31 is a U-shaped plate, and the first water baffle 31 surrounds three sides of the buoyancy member 22, and the side wall of one side of the box body 1 surrounds the fourth side of the buoyancy member 22, so as to fully oscillate the liquid in the box body 1 and achieve water vapor separation, thereby preventing the liquid from leaving the box body 1 from the outlet 12.

[0063] In some possible embodiments, the second water baffle plate 32 is a flat plate, and the second water baffle plate 32 extends toward a side wall of one side of the box body 1 .

[0064] In some other possible embodiments, the second water baffle 32 is an arc-shaped plate, and the second water baffle 32 extends toward the side wall of one side of the box body 1. At the same time, the second water baffle 32 is bent toward the outlet 12 side, thereby reducing the friction between the buoyancy member 22 and the water baffle assembly 3, so that the buoyancy of the buoyancy member 22 in the liquid is much greater than the friction, thereby increasing the conversion rate of the buoyancy member 22 between the vertical and horizontal states.

[0065] In some possible embodiments, when the box body 1 is in a vertical state, the first water baffle 31 and the side wall of the box body 1 enclose a subspace located in the second liquid storage space, and the subspace can accommodate the water outlet end of the water inlet pipe 21 carrying the buoyancy member 22; the radial dimension of the buoyancy member 22 is smaller than the inner diameter of the subspace, and there is a gap between the buoyancy member 22 and the first water baffle 31, and between the buoyancy member 22 and the side wall corresponding to the subspace. When the box body 1 is in a vertical state, the subspace can oscillate the liquid therein to achieve water vapor separation, thereby further ensuring the cleaning effect of the cleaning equipment.

[0066] Specifically, when the box body 1 is in a vertical state, as the liquid in the second liquid storage space continues to increase, part of the liquid is contained in the subspace. At this time, since the liquid in the box body 1 continues to move with the cleaning equipment, the liquid contained in the subspace continuously collides with the side wall of the subspace, thereby achieving separation of gas and liquid, and allowing the gas to flow out smoothly from the outlet 12.

[0067] In some possible embodiments, the water baffle assembly 3 also includes a third water baffle, which is arranged at the outlet 12 and is fixedly connected to the first end of the first water baffle 31; after the first water baffle 31, the second water baffle 32 and the third water baffle are connected to each other, a first liquid storage space is enclosed by the box body 1; the third water baffle is used to form a barrier between the first liquid storage space and the outlet 12. By arranging the third water baffle at the outlet 12, the first liquid storage space and the outlet 12 are blocked, and on the basis of ensuring the maximum liquid storage space at the corresponding angle, the liquid is prevented from flowing out of the box body 1 from the outlet 12 when the box body 1 is in a tilted or flat state, thereby ensuring the safety of the motor of the cleaning equipment.

[0068] In some possible embodiments, the water retaining assembly 3 includes a first water retaining member 31, a second water retaining member 32 and a third water retaining member, the second water retaining member 32 and the third water retaining member are relatively arranged on both sides of the first water retaining member 31, and the cross-section of the water retaining assembly 3 is an I-shaped member.

[0069] In some possible embodiments, when the box body 1 is in an inclined or horizontal state, the second end of the second water baffle 32 is higher than the highest limit surface of the liquid level in the box body 1. When the box body 1 is in an inclined or horizontal state, the second end of the second water baffle 32 is higher than the highest limit surface of the liquid level in the box body 1. This can prevent the liquid in the first liquid storage space from flowing to the outlet 12, and then prevent the liquid from flowing to the motor, thereby ensuring the safety of the motor.

[0070] In some possible embodiments, there is a gap between the second end of the second water baffle plate 32 and the side wall of one side of the box body 1 .

[0071] Specifically, the gap between the second end of the second water baffle plate 32 and the side wall of one side of the box body 1 is set according to actual conditions, and is not specifically limited here, as long as the second water baffle plate 32 can block the liquid.

[0072] Furthermore, by changing the gap between the second end of the second water baffle 32 and the side wall of one side of the box body 1, the liquid storage capacity of the first liquid storage space can be changed. The smaller the gap, the larger the liquid storage capacity, and the larger the gap, the smaller the liquid storage capacity.

[0073] In some possible embodiments, the first water baffle 31 and the second water baffle 32 are connected in an arc transition, the second water baffle 32 is an arc plate, the second water baffle 32 protrudes toward the bottom wall of the box body, and the second water baffle 32 is set to an arc plate, which can reduce the friction when the buoyancy member 22 contacts the second water baffle 32, so that the buoyancy member 22 rotates more smoothly; at the same time, by making an arc transition at the connection between the first water baffle 31 and the second water baffle 32, the friction between the buoyancy member 22 and the water baffle assembly 3 is further reduced, so that the buoyancy member 22 rotates more smoothly, thereby improving the switching rate of the box body 1 between the horizontal state and the vertical state.

[0074] Furthermore, the diameter of the arc at the connection between the first water baffle 31 and the second water baffle 32 is not limited and can be set according to actual conditions, as long as the friction between the first water baffle 31 and the second water baffle 32 is reduced so that the buoyancy member 22 can be smoothly switched between the horizontal state and the vertical state.

[0075] Furthermore, the diameter of the second water baffle plate 32 is not set, as long as the second water baffle plate 32 can reduce the friction between the second water baffle plate 32 and the buoyancy member 22 .

[0076] The second aspect of the present invention also protects a cleaning device, including a cleaning component, a body, a suction motor and a sewage tank of the above cleaning device; the body is rotatably connected to the cleaning component, the sewage tank and the motor are both installed on the body, and the motor is used to suck the sewage tank from the outlet 12. The cleaning device provided with the sewage tank can prevent the liquid in the sewage tank from flowing from the outlet 12 to the motor, thereby ensuring the working stability of the cleaning device and improving the service life of the cleaning device.

[0077] The working process of the sewage tank of the cleaning equipment: when the box body 1 is in a vertical state, the inner cavity of the box body 1 forms a second liquid storage space, the first water retaining assembly 31 and the box body 1 form a sub-space, the liquid is contained in the second liquid storage space, and the buoyancy member 22 drives the water inlet pipe 21 to be in a vertical state. When the liquid reaches a certain amount, the buoyancy member 22 is set in the sub-space, and the sub-space separates the gas and liquid in the liquid; when the box body 1 needs to be switched from a vertical state to a horizontal state, the buoyancy member 22 changes with the water surface, and then drives the water inlet pipe 21 to switch from a vertical state to a bent state. At this time, the water retaining assembly 3 and the box body 1 form a first liquid storage space, and the buoyancy member 22 drives the water outlet end of the water inlet pipe 21 to float on the liquid surface.

[0090] For example, see Figure 1 When the sewage tank of the cleaning equipment is in a horizontal state, the first water baffle 31, the second water baffle 32 and the third water baffle are connected to each other to form a first liquid storage space with the box body 1, and the third water baffle is used to form a barrier between the first liquid storage space and the outlet 12; the liquid in the sewage tank of the cleaning equipment is contained in the first liquid storage space, and the buoyancy member 22 drives the water inlet pipe 21 to bend the side wall toward one side of the box body 1, and the buoyancy member 22 floats on the liquid surface, so that the water outlet end of the water inlet pipe 21 is higher than the liquid surface.

[0091] Specifically, the second end of the second water baffle plate 32 is higher than the highest limit surface of the liquid level in the box body 1 .

[0092] Specifically, when the liquid in the box body 1 continues to increase, the liquid level in the first liquid storage space gradually rises, and the buoyancy member 22 drives the water outlet end of the water inlet pipe 21 to rise as the liquid level rises. At this time, the water inlet pipe 21 is lengthened under the action of the buoyancy member 22 to ensure that the water outlet end of the water inlet pipe 21 can float on the liquid surface with the buoyancy member 22; when the liquid in the box body 1 continues to decrease, the liquid level in the first liquid storage space gradually decreases, and the water inlet pipe 21 is shortened due to the gravity of itself and the buoyancy member 22 arranged thereon. At the same time, the buoyancy member 22 drives the water outlet end of the water inlet pipe 21 to float on the liquid surface.

[0093] For example, see Figure 2 When the sewage tank of the cleaning equipment is in a vertical state, the inner cavity of the box body 1 forms a second liquid storage space, and the first water baffle 31 and the side wall of the box body 1 enclose a subspace located in the second liquid storage space, and the subspace can accommodate the water outlet end of the water inlet pipe 21 carrying the buoyancy member 22; the radial dimension of the buoyancy member 22 is smaller than the inner diameter of the subspace, and there is a gap between the buoyancy member 22 and the first water baffle 31, as well as between the buoyancy member 22 and the side wall corresponding to the subspace; the liquid in the sewage tank of the cleaning equipment is contained in the second liquid storage space, and the buoyancy member 22 drives the water inlet pipe 21 to remain vertical, and the buoyancy member 22 floats on the liquid surface, so that the water outlet end of the water inlet pipe 21 is higher than the liquid surface.

[0094] Specifically, when the liquid in the box body 1 continues to increase, the liquid level in the second liquid storage space gradually rises, and the buoyancy member 22 drives the water outlet end of the water inlet pipe 21 to rise as the liquid level rises. At this time, the water inlet pipe 21 is lengthened under the action of the buoyancy member 22 to ensure that the water outlet end of the water inlet pipe 21 can float on the liquid surface with the buoyancy member 22; when the liquid in the box body 1 continues to decrease, the liquid level in the second liquid storage space gradually decreases, and the water inlet pipe 21 is shortened due to the gravity of itself and the buoyancy member 22 arranged thereon. At the same time, the buoyancy member 22 drives the water outlet end of the water inlet pipe 21 to float on the liquid surface.
