Description

Technical Field

[0001] The invention relates to the field of cleaning equipment, and in particular to a water tank waterproof surge structure and a cleaning robot. Background Art

[0002] In recent years, with the continuous increase in labor costs and the continuous advancement of intelligent property services, property cleaning robots are increasingly entering application scenarios such as residential communities, office buildings, and hospitals.

[0003] During use, property cleaning robots with a high level of intelligence mostly adopt an operating mode of automatic replenishment of clean water, automatic floor washing, and automatic discharge of sewage.

[0004] When the robot automatically replenishes clean water, the automatic replenishment of clean water often cannot be stopped in time due to poor sensitivity of the liquid level sensor and occasional delay in signal transmission, and the clean water overflows from the clean water tank replenishment port. During the autonomous movement of the robot, the robot often experiences varying degrees of bumps due to various reasons such as uneven ground and acceleration and deceleration of the robot, which in turn causes the clean water in the clean water tank to surge and the clean water to overflow from the replenishment port. In both of the above situations, the clean water overflowing from the replenishment port will enter the robot and cause great harm to the internal electrical components. In response to the above situation, the industry usually solves it by increasing the height difference between the replenishment port and the actual liquid level of the water tank. However, if the height difference is too large, a lot of the actual use volume of the water tank will be sacrificed, which will cause the overall volume of the robot to increase, and the lightweight size of the cleaning robot is a very important indicator. If the height difference is too small, it will only reduce the probability of clean water overflowing, and this problem cannot be completely solved. Therefore, the disadvantages of the above two methods are too obvious, and neither can be used as a better solution to the above problems.

[0005] In order to solve the above-mentioned problems of property cleaning robots, the present invention provides a clean water tank waterproof surge overflow structure and a cleaning robot with compact structure, reasonable layout and ingenious design. Summary of the invention

[0006] Based on this, the object of the present invention is to provide a clean water tank waterproof surge structure and a cleaning robot with compact structure, reasonable layout, ingenious conception, good buffering and shielding effect, and good anti-surge effect.

[0007] The clean water tank anti-surge structure of the present invention comprises:

[0008] Clean water tank;

[0009] A water injection part, which is arranged on the upper part of the clean water tank body and is communicated with the clean water tank body, and is provided with a water injection port;

[0010] A shielding buffer portion is connected between the clean water tank and the water injection portion.

[0011] The clean water tank waterproof surge prevention structure of the present invention arranges a shielding buffer part between the water filling part and the clean water tank body, and can utilize the shielding buffer part to buffer and shield the clean water, thereby reducing the intensity and impact force of the clean water surge, reducing the possibility of the clean water overflowing from the water filling part, and maximally utilizing the volume of the clean water tank body, thereby solving the problem of clean water entering the interior of the cleaning robot from the clean water tank body.

[0012] In one embodiment of the above technical solution, the bottom plate of the water injection part is tilted downward from the water injection port toward the clean water tank body. The bottom plate of the water injection part is tilted so that the clean water in the water injection part can flow toward the clean water tank body, preventing the clean water from accumulating in the water injection part.

[0013] In one implementation of the above technical solution, the shielding buffer portion includes a shielding portion and a buffer portion;

[0014] The shielding part is connected between the water injection part and the buffer part, and the buffer part is communicated with the clean water tank.

[0015] The shielding part and the buffering part respectively play the role of shielding and buffering the clean water, and can effectively reduce the intensity and impact force of the surging clean water.

[0016] In one embodiment of the above technical solution, the shielding part and the buffering part are arranged in a stepped shape from top to bottom. In this way, the clean water blocked by the shielding part can flow to the buffering part under the action of gravity and flow back into the clean water tank.

[0017] In one implementation of the above technical solution, the upper end of the shielding portion is higher than the plane where the bottom plate of the water injection portion is located;

[0018] A groove is provided in the middle of the shielding portion, and the bottom surface of the groove is lower than the plane where the bottom plate of the water injection portion is located.

[0019] The upper end of the shielding part is set to be higher than the plane where the bottom plate of the water injection part is located, so that the shielding part can block the impact of clean water and reduce the clean water entering the water injection part; the groove opened in the shielding part can guide the clean water in the water injection part to the buffer part to prevent the clean water from accumulating in the water injection part.

[0020] In one embodiment of the above technical solution, the bottom plate of the buffer part is inclined downward from the connection between the buffer part and the shielding part toward the clean water tank body. This arrangement allows the clean water to flow toward the clean water tank body under the action of gravity.

[0021] In one embodiment of the above technical solution, the clean water tank water surge protection structure further includes a shielding plate, which is vertically arranged in the space of the buffer portion. The shielding plate can form a first layer of shielding for the clean water, which can greatly reduce the amplitude and impact of the clean water surge.

[0022] In one implementation of the above technical solution, a long strip-shaped mounting hole is provided above the buffer portion;

[0023] The shielding plate is configured to be L-shaped, with its long side inserted into the mounting hole and its short side clamped outside the mounting hole.

[0024] Such arrangement enables the shielding plate to be detachable, which is convenient for disassembly, assembly and maintenance.

[0025] In one implementation of the above technical solution, an exhaust hole is provided at the upper portion of the shielding plate, and a drainage hole is provided at the lower portion thereof;

[0026] A gap is provided between the lower end of the shielding plate and the bottom plate of the buffer portion.

[0027] The exhaust hole allows the gas inside the clean water box to flow smoothly; the drainage hole allows clean water to pass through, so that the surging clean water will not have too much impact on the baffle; the set gap is conducive to the clean water to flow back to the clean water box.

[0028] The present invention further provides a cleaning robot, comprising any one of the above-mentioned clean water tank waterproof surge structures.

[0029] Compared with the prior art, the water tank water surging prevention structure and the cleaning robot of the present invention provide a shielding buffer part between the water injection part and the water tank body, and can use the shielding buffer part to buffer and shield the water, reduce the strength and impact of the water surge, reduce the possibility of water overflowing from the water injection part, and maximize the use of the volume of the water tank body, solving the problem of water entering the interior of the cleaning robot from the water tank body. The water tank water surging prevention structure and the cleaning robot of the present invention have the characteristics of compact structure, reasonable layout, ingenious design, good buffering and shielding effect, good anti-surging effect, etc.

[0038] The water-proof surge-proof structure of a clean water tank of the present invention comprises a clean water tank body 1 , a water injection portion 2 and a shielding buffer portion 3 .

[0039] The water injection part 2 is disposed on the upper part of the clean water tank body 1 , and the water injection part 2 is communicated with the clean water tank body 1 . The water injection part 2 is provided with a water injection port 21 .

[0040] The shielding buffer portion 3 is communicated between the clean water tank 1 and the water injection portion 2 .

[0041] By providing a shielding buffer portion 3 between the water injection portion 2 and the clean water tank body 1, the shielding buffer portion 3 can be utilized to buffer and shield the clean water, thereby reducing the intensity and impact force of the clean water surge, reducing the possibility of the clean water overflowing from the water injection portion 2, and maximizing the use of the volume of the clean water tank body 1, thereby solving the problem of clean water entering the interior of the cleaning robot from the clean water tank body 1.

[0042] Specifically, the water injection port 21 is opened on the side of the water injection part 2 .

[0043] Preferably, the bottom plate of the water injection part 2 is tilted downward from the water injection port 21 toward the clean water tank 1. The bottom plate of the water injection part 2 is tilted so that the clean water in the water injection part 2 can flow toward the clean water tank 1, preventing the clean water from accumulating in the water injection part 2.

[0044] Furthermore, the shielding buffer portion 3 includes a shielding portion 31 and a buffer portion 32 .

[0045] The shielding portion 31 is connected between the water injection portion 2 and the buffer portion 32 , and the buffer portion 32 is communicated with the clean water tank 1 .

[0046] The shielding portion 31 and the buffering portion 32 respectively play the role of shielding and buffering the clean water, and can effectively reduce the intensity and impact force of the surging clean water.

[0047] Preferably, the shielding portion 31 and the buffer portion 32 are arranged in a stepped shape from top to bottom. In this way, the clean water shielded by the shielding portion 31 can flow to the buffer portion 32 under the action of gravity and flow back into the clean water tank 1.

[0048] Furthermore, the upper end of the shielding portion 31 is higher than the plane where the bottom plate of the water injection portion 2 is located.

[0049] A groove is formed in the middle of the shielding portion 31 , and the bottom surface of the groove is lower than the plane where the bottom plate of the water injection portion 2 is located.

[0050] The upper end of the shielding portion 31 is set to be higher than the plane where the bottom plate of the water injection portion 2 is located, so that the shielding portion 31 can block the impact of clean water and reduce the clean water entering the water injection portion 2; the groove opened in the shielding portion 31 can guide the clean water in the water injection portion 2 to the buffer portion 32 to prevent the clean water from accumulating in the water injection portion 2.

[0051] Preferably, the bottom plate of the buffer portion 32 is inclined downward from the connection between the buffer portion 32 and the shielding portion 31 toward the clean water tank 1. This arrangement allows the clean water to flow toward the clean water tank 1 under the action of gravity.

[0052] Furthermore, the clean water tank water surge prevention structure further includes a shielding plate 4, which is vertically arranged in the space of the buffer portion 32. The shielding plate 4 can form a first layer of shielding for clean water, which can greatly reduce the amplitude and impact of clean water surge.

[0053] The shielding plate 4 of this embodiment is preferably configured to be detachable, specifically: a strip-shaped mounting hole 320 is provided above the buffer portion 32; the shielding plate 4 is configured to be L-shaped, with its long side inserted into the mounting hole 320 and its short side clamped outside the mounting hole 320. The shielding plate 4 is configured to be detachable, which is convenient for disassembly and maintenance.

[0054] Preferably, an exhaust hole is provided at the upper part of the shielding plate 4, and a drainage hole is provided at the lower part thereof. The exhaust hole and the drainage hole are both arranged as vertically oblong holes, and the exhaust hole and the drainage hole are preferably arranged in a row in the horizontal direction.

[0055] A gap is provided between the lower end of the shielding plate 4 and the bottom plate of the buffer portion 32 .

[0056] The exhaust hole allows the gas inside the clean water box 1 to flow smoothly; the drainage hole allows clean water to pass through, so that the surging clean water will not have too much impact on the baffle 4; the set gap is conducive to the clean water to flow back to the clean water box 1.

[0057] The water injection part 2, the shielding buffer part 3 and the clean water tank body 1 can be formed by rotational molding at one time. The structure of each part is very easy to realize, and no other parts need to be added. The design is ingenious and greatly reduces the workload of processing and assembly. In addition, the clean water tank waterproof surge structure of the present invention maximizes the use of the volume of the clean water tank body 1, without wasting the volume of this part, meeting the requirements of lightweight and compact structure of the cleaning robot.

[0058] The clean water tank waterproof surge structure of the present invention is suitable for a cleaning robot with automatic sewage discharge.

[0059] The working principle of the clean water tank waterproof surge structure of the present invention:

[0060] Insert the water supply pipe into the water inlet 21, and fill water into the clean water tank 1. The clean water flows to the water injection part 2, passes through the shielding part 31 and the buffer part 32, and enters the clean water tank 1 until it is flush with the plane where the groove is located (plane A in the figure), and the clean water supply is completed. In the static state, plane A is the highest level of the clean water in the clean water tank. At this time, there is no clean water in the water injection part 2.

[0061] When the cleaning robot is in a bumpy state, the clean water in the clean water tank 1 will surge violently, and the surging clean water will first pass through the shielding plate 4. For the surging clean water, the shielding plate 4 will greatly reduce the amplitude of the surging clean water and the strength of the impact.

[0062] When the clean water with greatly weakened surging condition flows to the shielding portion 31, most of the clean water can be shielded on the side of the shielding portion 31 close to the clean water tank 1. A small amount of clean water flowing to the water injection portion 2 has a very small surging amplitude at this time, and the water volume is very small, so this part of clean water cannot flow out through the water injection port 21, and this part of clean water can flow back into the clean water tank 1 through the groove and the buffer portion 32.

[0063] The present invention further provides a cleaning robot, comprising the clean water tank waterproof surge prevention structure.

[0064] The application scenarios of the cleaning robot of the present invention include large shopping malls, airports, factories, libraries, railway stations, theaters and other places that require large-scale cleaning.

[0065] Compared with the prior art, the water tank water surging prevention structure and the cleaning robot of the present invention provide a shielding buffer part 3 between the water injection part 2 and the water tank body 1, and can use the shielding buffer part 3 to buffer and shield the water, reduce the strength and impact of the water surge, reduce the possibility of the water overflowing from the water injection part 2, and maximize the use of the volume of the water tank body 1, solving the problem of the water entering the cleaning robot from the water tank body 1. The water tank water surging prevention structure and the cleaning robot of the present invention have the characteristics of compact structure, reasonable layout, ingenious design, good buffering and shielding effect, good anti-surging effect, etc.

[0066] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
