Description

Technical Field

[0001] This utility model relates to the technical field of cleaning tools, specifically to a surface cleaning machine and surface cleaning system. Background Technology

[0002] Carpet cleaners, such as carpet cleaners, are specifically designed for cleaning soft surfaces like carpets and rugs. They efficiently remove stains and impurities from carpet fibers. Generally, they include a clean water tank and a wastewater tank. The clean water tank stores clean water or a mixture of cleaning agents. By spraying the cleaning solution onto the carpet, the stains are broken down more quickly, separating the dirt from the carpet. The cleaner then draws the water containing the dirt into the machine, collecting the wastewater in the wastewater tank. Traditionally, to optimize space utilization between the brush mechanism and the main body, the wastewater tank is typically located on the brush mechanism, while the clean water tank is on the main body. Since the main body is mostly positioned at an angle to the brush mechanism during operation, much of the machine's weight is borne by the user's hands, making operation more strenuous and resulting in a poor user experience. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the main purpose of this utility model is to provide a surface cleaning machine and a surface cleaning system, which aims to solve the problem that traditional surface cleaning machines are heavy and require a lot of effort from users, resulting in a poor user experience.

[0004] To achieve the above objectives, this utility model proposes a surface cleaning machine, comprising:

[0007] The main body is rotatably connected to the floor brush mechanism to have a placement position and a working position. The main body has clearance space so that when the clean water tank and / or the wastewater tank is located on the floor brush mechanism, the main body can switch between the placement position and the working position.

[0008] When the main body of the machine is in the placement position, the projection of the main body of the machine in the orthographic projection along the left and right direction of the floor brush mechanism at least partially overlaps with the projection of at least one of the clean water tank and the wastewater tank.

[0011] Optionally, when the main body of the machine is in the placement position, the projection of the main body of the machine overlaps at least partially with the projection of the clean water tank and / or the projection of the wastewater tank on the orthographic projection along the left and right directions of the floor brush mechanism.

[0012] Optionally, the wastewater tank is located in front of the clean water tank;

[0013] Along the left-right direction of the floor brush mechanism, the width of the wastewater tank is greater than the width of the clean water tank, and the connection between the main body of the machine and the floor brush mechanism is provided on the left and right sides of the clean water tank.

[0014] Optionally, when in the aforementioned placement position, both the left and right sides of the main body of the machine are not protruding from the left and right sides of the sewage tank.

[0015] Optionally, the main body includes a main body and two connecting arms that are spaced apart from each other on the main body, and both connecting arms are rotatably connected to the floor brush mechanism;

[0016] When in the aforementioned placement position, the two connecting arms are located on both sides of the water tank along the left-right direction of the floor brush mechanism, such that the main body and the top of the water tank are spaced apart.

[0017] Optionally, when in the placement position, the projection of each connecting arm overlaps at least partially with the projection of the clean water tank on the orthographic projection along the left-right direction of the floor brush mechanism.

[0018] Optionally, the floor brush mechanism has a first receiving cavity with its opening facing upwards, at least a portion of the clean water tank is housed within the first receiving cavity, and when the main body is in the placement position, the clean water tank has space to be removed from the first receiving cavity.

[0019] Optionally, when in the placement position, the distance between the main body and the top of the water tank is greater than the depth to which the bottom of the water tank is inserted into the first receiving cavity.

[0020] Optionally, the opening of the first accommodating cavity protrudes with a first limiting protrusion, which is located on the side of the first accommodating cavity near the sewage tank.

[0021] The clean water tank is provided with a first limiting groove that cooperates with the first limiting protrusion, and the first limiting groove is open on the side facing the sewage tank;

[0022] The first limiting groove is provided with a first buckle, the first limiting protrusion is accommodated in the first limiting groove, and at least a portion of the first limiting protrusion is engaged with the first buckle to restrict the clean water tank from moving in a direction away from the sewage tank.

[0023] Optionally, the floor brush mechanism has a second receiving cavity with its opening facing upwards. The opening of the second receiving cavity protrudes with a second limiting protrusion, which is located on the side of the second receiving cavity closer to the clean water tank.

[0024] The wastewater tank is provided with a second limiting groove that cooperates with the second limiting protrusion. The second limiting groove is provided with a second buckle. The second limiting protrusion is accommodated in the second limiting groove, so that at least a portion of the second limiting protrusion is engaged with the second buckle to restrict the wastewater tank from moving in a direction away from the clean water tank.

[0025] This utility model also provides a surface cleaning system, including a base and the aforementioned surface cleaning machine, wherein the surface cleaning machine can be placed on the base.

[0026] The technical solution provided by this utility model has the following beneficial effects:

[0027] This utility model provides a surface cleaning machine, including a floor brush mechanism, a clean water tank, a wastewater tank, and a main body. The main body can rotate relative to the floor brush mechanism. When the surface cleaning machine is cleaning, the main body can be rotated to the working position, where it is at an angle convenient for the user to push and pull, facilitating cleaning of various areas. When the surface cleaning machine is finished or not in use, the main body can be placed roughly vertically, ensuring the center of gravity is roughly vertical, preventing tipping and facilitating storage. Furthermore, by placing both the clean water tank and the wastewater tank on the floor brush mechanism, the weight of the main body is effectively reduced, making it easier for the user to operate and improving the user experience. Furthermore, the clean water tank and waste water tank are independently and detachably mounted on the floor brush mechanism. When the clean water tank is empty, it is easier to remove and refill it promptly; when the waste water tank is full, it is also easier to empty it. The operation of the clean water and waste water tanks is more flexible and convenient. Moreover, the main body of the machine has a clearance space, allowing the main body to switch between its placement and working positions whether the clean water tank and / or waste water tank are on or removed from the floor brush mechanism. The placement and removal of the clean water and / or waste water tanks are not limited by the position of the main body, making the usage more flexible and convenient for users. Furthermore, the clean water tank and the wastewater tank are arranged along the front-to-back direction, and when the main body of the machine is in the placement position, the projection of the main body of the machine overlaps at least partially with the projection of at least one of the clean water tank and the wastewater tank on the orthographic projection along the left-to-right direction of the floor brush mechanism, so that at least part of the main body of the machine is located to the left and / or right of the clean water tank and / or the wastewater tank. This allows the clean water tank, the wastewater tank and the main body of the machine to occupy less space together along the front-to-back direction of the floor brush body, making the structure more compact and the overall size of the surface cleaning machine smaller.

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] It should be noted that if the embodiments of this utility model involve directional indication, the directional indication is only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0044] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0045] This utility model provides a surface cleaning machine 100, which can be used to clean surfaces to be cleaned, especially soft surfaces such as carpets and floor mats. For details, please refer to... Figure 1 , Figure 2 and Figure 4 In this embodiment, the surface cleaning machine 100 includes a floor brush mechanism 1, a clean water tank 3, a wastewater tank 4, and a main body 2.

[0046] The clean water tank 3 and the wastewater tank 4 are detachably mounted on the floor brush mechanism 1 and are arranged along the front-rear direction of the floor brush mechanism 1. The main body 2 is rotatably connected to the floor brush mechanism 1 to have a placement position and a working position. The main body 2 has clearance space so that when the clean water tank 3 and / or the wastewater tank 4 are located on the floor brush mechanism 1, the main body 2 can switch between the placement position and the working position. When the main body 2 is in the placement position, the projection of the main body 2 on the orthographic projection along the left-right direction of the floor brush mechanism 1 at least partially overlaps with the projection of at least one of the clean water tank 3 and the wastewater tank 4.

[0047] In this embodiment, when the surface cleaning machine 100 is performing cleaning work, the main body 2 is rotated to the working position. At this time, the main body 2 forms a certain angle with the surface to be cleaned, and the main body 2 is positioned at an angle that facilitates push-pull operation by the user, making it convenient for the user to move the surface cleaning machine 100 to clean various areas. When the surface cleaning machine 100 has finished cleaning or is not in use, the main body 2 can be placed in a roughly vertical position. This position ensures that the center of gravity of the main body 2 is roughly in the vertical direction, better preventing the main body 2 from tipping over and facilitating storage.

[0048] Furthermore, by placing both the clean water tank 3 and the wastewater tank 4 on the floor brush mechanism 1, the weight of the clean water tank 3 itself and the clean water inside, and the weight of the wastewater tank 4 itself and the wastewater inside, are directly applied to the floor brush mechanism 1, not to the main body 2. This effectively reduces the weight of the main body 2. Especially when the surface cleaner 100 first enters the cleaning state, the water level in the clean water tank 3 is at or near full, and the overall weight of the clean water tank 3 is relatively heavy. Therefore, placing the clean water tank 3 on the floor brush mechanism 1 reduces the weight of the main body 2 that the user's hand bears when using the surface cleaner 100, making it easier to use and improving the user experience. Moreover, the clean water tank 3 and the wastewater tank 4 are each independently and detachably mounted on the floor brush mechanism 1. When the clean water tank 3 is empty, it is easier to remove it for refilling, and when the wastewater tank 4 is full, it is easier to empty it. The operation of the clean water tank 3 and the wastewater tank 4 is relatively independent, flexible, and convenient. Furthermore, the main body 2 has a clearance space, which allows the main body 2 to switch between the placement position and the working position when the clean water tank 3 and / or the waste water tank 4 are placed on or removed from the floor brush mechanism 1. The placement and removal of the clean water tank 3 and / or the waste water tank 4 are not limited by the position of the main body 2, making the use more flexible and convenient for users.

[0049] Furthermore, the clean water tank 3 and the wastewater tank 4 are arranged along the front-to-back direction, and when the main body 2 is in the placement position, the projection of the main body 2 in the left-to-right direction along the floor brush mechanism 1 at least partially overlaps with the projection of the clean water tank 3 and / or the wastewater tank 4, so that at least part of the main body 2 is located to the left and / or right of the clean water tank 3 and / or the wastewater tank 4. This allows the clean water tank 3, the wastewater tank 4 and the main body 2 to occupy less space in the front-to-back direction along the floor brush body 11, making the structure more compact and the overall size of the surface cleaning machine 100 smaller.

[0050] Among them, combined Figure 2 and Figure 4 As shown, the main body 2 is roughly shaped like an inverted "U". The main body 2 includes a main body 21 and two connecting arms 22 spaced apart from each other on the main body 21. Both connecting arms 22 are rotatably connected to the floor brush mechanism 1. The main body 21 has a roughly elliptical cylindrical structure, and the two connecting arms 22 are located at one axial end of the main body 21. The surface cleaning machine 100 also includes a handle structure 23 located at the other axial end of the main body 21.

[0051] It should be noted that when the surface cleaner 100 is not in operation, the main body 2 is in a resting position. At this time, the axial direction of the main body 21 is slightly tilted in the vertical direction to ensure that the center of gravity of the main body 2 is approximately vertical, preventing it from tipping over. Two connecting arms 22 are located at the bottom of the main body 21, and the handle structure 23 is connected to the top of the main body 21. The bottom surface of the floor brush mechanism 1 faces the surface to be cleaned; when the surface cleaner 100 is placed on the ground, the bottom surface of the floor brush mechanism 1 faces the ground. When the surface cleaner 100 is working normally on the ground, the forward direction of the surface cleaner 100 is in front of the floor brush mechanism 1, and the backward direction of the surface cleaner 100 is behind the floor brush mechanism 1. The main body 2 is preferably able to rotate along the front and back direction of the floor brush mechanism 1. When switching from the placement position to the working position, the main body 2 rotates backward and is set at a certain angle with the ground to be in the working position, so that the user can stand on the back side of the surface cleaning machine 100 to push and pull the handle structure 23, thereby moving the surface cleaning machine 100.

[0052] Preferably, combined with Figure 9 As shown, Figure 9The diagram illustrates the main body 2 in various working positions: vertical (placement position), horizontal or near-horizontal (extreme working position), and a general working position between the placement and extreme working positions. When the main body 2 is in the working position, the angle θ between the main body 2 and the horizontal plane is less than 90°. The working position is not limited to a specific location; it can refer to the position of the main body 2 when θ is less than 90°. This allows the main body 2 to rotate to an angle that facilitates user gripping of the handle structure 23, making it easier and less strenuous for the user to move the surface cleaning machine 100. Unless otherwise specified, descriptions of orientation in this invention shall be taken as above.

[0053] Depending on the placement and size of the clean water tank 3 and the wastewater tank 4, the connection position between the main body 2 and the floor brush mechanism 1 can be reasonably set. This allows the two connecting arms 22 of the main body 2 to be positioned on the left and right sides of the clean water tank 3 and / or the wastewater tank 4, respectively, with each connecting arm 22 not protruding from or slightly protruding from the clean water tank 3 or the wastewater tank 4 in the left-right direction. Preferably, when in the placement position, the projection of each connecting arm 22 on the orthographic projection along the left-right direction of the floor brush mechanism 1 at least partially overlaps with the projection of the clean water tank 3. Positioning the main body 2 close to the rear end of the floor brush mechanism 1 facilitates switching between the placement and working positions, and also prevents the main body 2 from occupying excessive space in the front-back direction.

[0054] The front-to-back direction of the floor brush mechanism 1 is set as its length direction, and the left-to-right direction of the floor brush mechanism 1 is set as its width direction. The projections of the main body 2 and the clean water tank 3 and / or the wastewater tank 4 in the front-to-back and left-to-right directions overlap at least partially, so that the space occupied by the main body 2, the clean water tank 3 and the wastewater tank 4 in the front-to-back and left-to-right directions is smaller. Therefore, the overall length and width of the floor brush mechanism 1 are smaller, the volume of the floor brush mechanism 1 is smaller, and thus the volume of the entire surface cleaning machine 100 is smaller.

[0055] In one embodiment, the projections of the clean water tank 3 and the wastewater tank 4 at least partially overlap in the orthographic projection along the front-back direction of the floor brush mechanism 1. This ensures that the clean water tank 3 and the wastewater tank 4 are not completely offset in the left-right direction, and the combined width occupied by the clean water tank 3 and the wastewater tank 4 in the left-right direction is less than the sum of their individual widths. Therefore, the space occupied by the clean water tank 3 and the wastewater tank 4 in the left-right direction can be smaller, resulting in a smaller width for the floor brush mechanism 1.

[0056] Because the wastewater tank 4 has many internal structures, such as separation structures for gas-liquid separation, antibacterial structures, and / or float structures, these structures occupy a significant amount of storage volume within the wastewater tank 4. Therefore, preferably, in the orthographic projection along the front-rear direction of the floor brush mechanism 1, the projection of the clean water tank 3 lies within the projection of the wastewater tank 4. Both the clean water tank 3 and the wastewater tank 4 are approximately square in shape, with the length directions of both coinciding with the length direction of the floor brush mechanism 1, and the width directions of both coinciding with the width direction of the floor brush mechanism 1.

[0057] In one embodiment, with the widths of the clean water tank 3 and the wastewater tank 4 being approximately the same, the length of the wastewater tank 4 is set to be greater than the length of the clean water tank 3. This allows the actual storage volume of the wastewater tank 4 to be larger, and the storage volume of the wastewater tank 4 to be closer to the volume of the clean water tank 3, thus ensuring better wastewater storage capacity.

[0058] In another embodiment, when the lengths of the clean water tank 3 and the wastewater tank 4 are approximately the same, the width of the wastewater tank 4 is set to be greater than the width of the clean water tank 3. Similarly, this allows the actual storage volume of the wastewater tank 4 to be larger, and avoids the surface cleaning machine 100 from needing to frequently discharge wastewater due to the small volume of the wastewater tank 4, effectively saving discharge time and improving the cleaning efficiency of the surface cleaning machine 100.

[0059] Furthermore, a suction port is provided at the front end of the floor brush mechanism 1, and the suction port is connected to the wastewater tank 4. The wastewater tank 4 is used to store wastewater mixed with dirt sucked in by the suction port. Preferably, combined with Figure 1 , Figure 4 and Figure 5 As shown, the wastewater tank 4 is located in front of the clean water tank 3, which allows the wastewater tank 4 to be closer to the suction port, making the connecting pipe between the suction port and the wastewater tank 4 shorter and simpler. The wastewater has a shorter flow path, less flow resistance, and higher flow efficiency, thus making the suction efficiency of the surface cleaning machine 100 higher.

[0060] Preferably, in the left and right directions along the floor brush mechanism 1, the sewage tank 4 and the clean water tank 3 are both centered with the floor brush mechanism 1, so that the center of gravity of the sewage tank 4 and the clean water tank 3 can be better placed at the center of the floor brush mechanism 1, ensuring that the floor brush mechanism 1 is more stable when moving.

[0061] When the width of the wastewater tank 4 is greater than the width of the clean water tank 3, the connection between the main body 2 and the floor brush mechanism 1 is positioned on the left and right sides of the clean water tank 3. Furthermore, when in the designated placement position, both the left and right sides of the main body 2 are positioned to correspond to, but not protrude from, the left and right sides of the wastewater tank 4. This ensures that the combined width of the main body 2 and the clean water tank 3 is still less than the width of the wastewater tank 4. The more compact arrangement between the main body 2 and the clean water tank 3 allows for a smaller overall width dimension of the floor brush mechanism 1.

[0062] Specifically, the two connecting arms 22 of the main body 2 are rotatably connected to the left and right sides of the floor brush mechanism 1 located on the water tank 3. This arrangement ensures that when the main body 21 is in the placement position, there is a gap between it and the top of the water tank 3. This prevents the main body 21 from interfering with the water tank 3 during rotation, and also provides sufficient space for the water tank 3 to be removed from the floor brush mechanism 1 when the main body 2 is in the placement position, making the use of the water tank 3 more flexible and convenient.

[0063] Furthermore, the floor brush mechanism 1 includes a floor brush body 11 and two rollers 12 disposed on the floor brush body 11, with the two rollers 12 symmetrically arranged on the left and right sides of the floor brush body 11. The two rollers 12 are positioned near the rear end of the floor brush body 11, and the clean water tank 3 is located between the two rollers 12. Two connecting arms 22 are respectively connected to the interval area between each roller 12 and the clean water tank 3.

[0064] Specifically, in combination Figures 1 to 3 As shown, the floor brush mechanism 1 also includes two axles 13 mounted on the floor brush body 11. The two axles 13 are fixed to the floor brush body 11, and two rollers 12 are rotatably connected to the two axles 13. Each end of the connecting arm 22 of the main body 2 is provided with a bushing 221, which is arranged in a ring shape. The two bushings 221 are rotatably fitted onto the outside of the two axles 13. Preferably, each roller 12, the corresponding axle 13, and the bushing 221 are coaxially arranged. When the main body 2 rotates relative to the floor brush mechanism 1, the rotating part of the main body 2 always remains coaxial with the rotation center of the roller 12. Therefore, when pushing or pulling the handle structure 23 on the main body 2, the force acts perpendicularly on the straight line where the rotation axis of the roller 12 is located. There is no torque between the force and the rotation axis of the roller 12, so it is easier to drive the roller 12 to rotate and the operation is easier.

[0065] The floor brush mechanism 1 is provided with a placement area for placing the clean water tank 3 and the wastewater tank 4. Limiting structures for restricting the movement of the clean water tank 3 and the wastewater tank 4 can be provided in the placement area and / or around the perimeter of the placement area, thereby ensuring that the clean water tank 3 and the wastewater tank 4 are not easily tipped over or moved during the operation of the surface cleaning machine 100, and ensuring the stability of the clean water tank 3 and the wastewater tank 4 during operation.

[0066] It is understood that the placement area can be configured as a placement plane, a placement groove, or a cavity structure for placement, etc. The specific configuration can be reasonably determined based on the volumes of the clean water tank 3 and the wastewater tank 4, and is not specifically limited here.

[0067] Since the surface cleaning machine 100 moves in various directions, such as front-to-back and left-to-right, during the cleaning process, the clean water tank 3 and the wastewater tank 4 also tend to tilt or move in various directions. Therefore, preferably, the placement area can be configured as a cavity structure to surround the outer periphery of the clean water tank 3 and the wastewater tank 4, so that the movement of the clean water tank 3 and the wastewater tank 4 can be restricted in all directions around them, thus better limiting their movement.

[0068] Specifically, in combination Figure 4 and Figure 8 As shown, a first receiving cavity 111 with its opening facing upwards is formed on the floor brush mechanism 1. At least a portion of the clean water tank 3 is housed within the first receiving cavity 111, and the clean water tank 3 can be removed from the first receiving cavity 111 when the main body 2 is in the placement position. By placing at least a portion of the clean water tank 3 within the first receiving cavity 111, for example, by housing the bottom of the clean water tank 3 within the first receiving cavity 111, and by having the cavity wall of the first receiving cavity 111 close to or abutting against the outer periphery of the bottom of the clean water tank 3, the horizontal movement of the clean water tank 3 can be restricted. Moreover, since the opening of the first receiving cavity 111 faces upwards, the clean water tank 3 can be easily removed and placed into the first receiving cavity 111, making the removal and placement of the clean water tank 3 flexible and simple to operate.

[0069] It is understandable that when the water tank 3 is removed from the first receiving cavity 111, it can be moved upward to be removed from the opening of the first receiving cavity 111; or, a notch is provided on one side of the cavity wall of the first receiving cavity 111, and the water tank 3 can be removed from the side of the first receiving cavity 111 with the notch.

[0070] When the wastewater tank 4 is located in front of the clean water tank 3 and the two connecting arms 22 are located on both sides of the clean water tank 3, preferably, the clean water tank 3 can be removed from the rear side of the first accommodating cavity 111, so that there is enough space to operate the clean water tank 3.

[0071] In one embodiment, when in the placement position, the distance between the main body 21 and the top of the water tank 3 is greater than the depth to which the bottom of the water tank 3 is inserted into the first receiving cavity 111. Specifically, the distance between the top of the main body 21 and the top of the water tank 3 refers to the distance between the top surface of the water tank 3 and the first surface of the main body 21 connected between the two connecting arms 22, and this first surface faces the top surface of the water tank 3. The bottom of the water tank 3 refers to the surface that contacts the bottom of the first receiving cavity 111 when the water tank 3 is placed inside the first receiving cavity 111. In the placement position, the water tank 3 has sufficient space to move upwards to completely remove itself from the first receiving cavity 111, and sufficient space to be inserted into the opening of the first receiving cavity 111.

[0072] In another embodiment, combined Figure 4 and Figure 5 As shown, a first limiting protrusion 1111 protrudes from the opening of the first accommodating cavity 111, and the first limiting protrusion 1111 is located on the side of the first accommodating cavity 111 near the sewage tank 4. A first limiting groove 31 is provided on the clean water tank 3 for the first limiting protrusion 1111 to cooperate with it. Specifically, at least a portion of the side wall of the clean water tank 3 can be recessed inward toward the inside of the clean water tank 3 to form the first limiting groove 31. When the clean water tank 3 is placed in the first accommodating cavity 111, the first limiting protrusion 1111 can be accommodated in the first limiting groove 31. Through the limiting cooperation between the groove side wall of the first limiting groove 31 and the first limiting protrusion 1111, the movement of the clean water tank 3 in the horizontal direction can be restricted, and the placement direction of the clean water tank 3 can be quickly and easily confirmed, ensuring that the clean water tank 3 is correctly placed in the first accommodating cavity 111.

[0073] The first limiting groove 31 is open on the side facing the sewage tank 4, so that the first limiting protrusion 1111 can be more easily locked into the first limiting groove 31 when the clean water tank 3 is placed. Moreover, a first fastening part 32 is provided in the first limiting groove 31. At least a part of the first limiting protrusion 1111 is fastened to the first fastening part 32 to restrict the movement of the clean water tank 3 away from the sewage tank 4, thereby ensuring that the clean water tank 3 can be restricted in all horizontal directions after being placed in the first receiving cavity 111, and is not easy to move.

[0074] Furthermore, combined Figures 4 to 6As shown, the first buckle 32 includes a limiting rib 321 protruding from the side wall of the first limiting groove 31. The limiting rib 321 is located on at least one side wall of the first limiting groove 31 along the left-right direction of the floor brush mechanism 1, and forms a stop-and-abutment fit with the first limiting protrusion 1111 along the front-back direction of the floor brush mechanism 1. Preferably, a limiting rib 321 protrudes from both the left and right side walls of the first limiting groove 31 along the water tank 3. By abutting against the left and right sides of the front surface of the first limiting protrusion 1111, the forward movement of the first limiting protrusion 1111 can be restricted, thereby restricting the forward movement of the entire water tank 3. Furthermore, each limiting rib 321 has a chamfer at its bottom. The distance between the two chamfers gradually increases in the direction from top to bottom. Through the guiding effect of the two chamfers, the first limiting protrusion 1111 can be smoothly inserted between the two limiting ribs 321, making it easier for the water tank 3 to be placed into the first receiving cavity 111.

[0075] like Figure 5 As shown, the first receiving cavity 111 has a first cavity wall 1112 located near the rear end of the floor brush mechanism 1. The first cavity wall 1112 extends obliquely in the direction from bottom to top along the floor brush mechanism 1, and the distance between it and the wastewater tank 4 gradually increases, i.e., the first cavity wall 1112 is obliquely arranged from front to back. The first receiving cavity 111 is generally square in shape, having two side walls arranged opposite each other in the front-back direction and two side walls arranged opposite each other in the left-right direction. The first cavity wall 1112 is the side wall located at the rear end of the first receiving cavity 111. A guide surface 33 is provided at the bottom of the outer wall of the clean water tank 3, with the oblique direction of the first cavity wall 1112 being consistent. The guide surface 33 is located on the rear side of the clean water tank 3, and a wedge-shaped fit is formed between the guide surface 33 and the first cavity wall 1112. When the guide surface 33 moves upward along the first cavity wall 1112, the guide surface 33 will also move backward along the first cavity wall 1112. That is, the entire clean water tank 3 can move upward and backward, thereby disengaging from the first receiving cavity 111. The user's force direction can be better along the moving direction of the clean water tank 3, making the operation easier.

[0076] Moreover, combined Figure 6 and Figure 8As shown, a protrusion 34 protrudes from the bottom of the clean water tank 3 and communicates with its inner cavity. The bottom of the first receiving cavity 111 has a recess 1113 that mates with the protrusion 34. Through the insertion and engagement of the protrusion 34 and the recess 1113, the clean water tank 3 can be further ensured to be placed stably and reliably within the first receiving cavity 111, preventing it from tipping over. Multiple protrusions 34 and multiple recesses 1113 can be provided, with each recess corresponding to a protrusion 34. Furthermore, the spacing between the peripheral walls of the recesses 1113 gradually increases from bottom to top, forming an upward-facing flared shape to facilitate the insertion of the protrusion 34. The outer peripheral surface of the protrusion 34 and the peripheral wall of the recess 1113 are inclined in a matching manner. This makes removing and inserting the clean water tank 3 smoother and easier.

[0077] It is understood that a wastewater tank 4 is provided on the front side of the clean water tank 3, and connecting arms 22 are provided on the left and right sides of the clean water tank 3. Therefore, when the main body 2 is in the placement position, it is preferable that the clean water tank 3 can be taken out and put in from the rear end of the main body 11.

[0078] Specifically, taking the removal of the clean water tank 3 as an example, when the user retrieves the clean water tank 3, the user's hand applies an upward force to the clean water tank 3 from the rear, allowing the clean water tank 3 to move upward so that the first limiting protrusion 1111 can disengage from the first buckle 32. Then, guided by the first cavity wall 1112 and the guide surface 33, the clean water tank 3 can tilt backward, allowing the user to smoothly remove the clean water tank 3 from the first receiving cavity 111 along the guiding direction. Since the clean water tank 3 does not need to maintain a vertically upward movement, the upward movement stroke of the clean water tank 3 can be shorter. Therefore, the gap between the main body 21 of the machine body 2 and the clean water tank 3 when in the placement position can be set smaller, the vertical dimension of the machine body 2 can be smaller, and the overall volume of the surface cleaning machine 100 is also smaller.

[0079] In one embodiment, combined with Figure 5 and Figure 8As shown, the first limiting protrusion 1111 is telescopically movable along the vertical direction of the floor brush mechanism 1. Specifically, a first boss protrudes from the opening of the first accommodating cavity 111, and the first boss is located on the side of the first accommodating cavity 111 near the sewage tank 4. The first boss is hollow, and a first opening is provided at the top of the first boss. The surface cleaning machine 100 also includes a first elastic member 51 disposed in the first boss, and the two ends of the first elastic member 51 are respectively connected to the first boss and the first limiting protrusion 1111, so that the height of the first limiting protrusion 1111 extending out of the first opening can be adjusted. In this way, when the water tank 3 is placed in the first receiving cavity 111, the first limiting protrusion 1111 can play a buffering role, avoiding excessive impact on the floor brush mechanism 1 when the water tank 3 is placed. Moreover, after the water tank 3 is placed in place, the first limiting protrusion 1111 can be kept in the position of engaging with the limiting rib 321 on the water tank 3 under the elastic action of the first elastic member 51, ensuring more reliable limiting of the water tank 3.

[0080] For the wastewater tank 4, the limiting method is similar to that of the clean water tank 3. Depending on the specific structure of the wastewater tank 4, the floor brush mechanism 1 is equipped with a corresponding matching structure. Specifically, combined with... Figure 4 and Figure 8 As shown, a second receiving cavity 112 with its opening facing upward is formed on the floor brush mechanism 1. The second receiving cavity 112 is located in front of the first receiving cavity 111. Preferably, the second receiving cavity 112 and the first receiving cavity 111 share a cavity wall, that is, the rear cavity wall of the second receiving cavity 112 and the front cavity wall of the first receiving cavity 111 are integrally formed, making the structure more compact and occupying less space.

[0081] A second limiting protrusion 1124 protrudes from the opening of the second accommodating cavity 112, and is located on the side of the second accommodating cavity 112 near the clean water tank 3. The wastewater tank 4 is provided with a second limiting groove 45 that cooperates with the second limiting protrusion 1124. Specifically, a portion of the side wall of the wastewater tank 4 can be recessed to form the second limiting groove 45. When the wastewater tank 4 is placed in the second accommodating cavity 112, the second limiting protrusion 1124 can be accommodated in the second limiting groove 45. Through the limiting cooperation between the side wall of the second limiting groove 45 and the second limiting protrusion 1124, the horizontal movement of the wastewater tank 4 can be restricted, and the placement direction of the wastewater tank 4 can be quickly and easily confirmed, ensuring the accuracy of the placement direction of the wastewater tank 4.

[0082] The second limiting groove 45 is open on the side facing the clean water tank 3, so that the second limiting protrusion 1124 can be more easily engaged in the second limiting groove 45 when the wastewater tank 4 is placed. A second fastening part 46 is provided in the second limiting groove 45, and the second limiting protrusion 1124 is accommodated in the second limiting groove 45, so that at least a part of the second limiting protrusion 1124 is engaged with the second fastening part 46 to restrict the wastewater tank 4 from moving in the direction away from the clean water tank 3, so as to prevent the wastewater tank 4 from easily tipping forward during the movement of the surface cleaning machine 100.

[0083] Furthermore, combined Figure 5 , Figure 7 and Figure 8 As shown, a retaining wall 43 protrudes from the bottom of the sewage tank 4. The retaining wall 43 can be inserted into the inner side of the second receiving cavity 112, so that the bottom of the sewage tank 4 rests on the opening of the second receiving cavity 112. The retaining wall 43 or the limiting rib 321 on the outer periphery of the retaining wall 43 cooperates with the cavity sidewall of the second receiving cavity 112, thereby restricting the horizontal movement of the sewage tank 4. Preferably, the retaining wall 43 can be provided in two layers to better ensure the fitting strength of the retaining wall 43.

[0084] The enclosure 43 is not a complete circle, but has a clearance notch 44 on one side. A limiting protrusion 1123 is provided on one side of the second receiving cavity 112 to mate with the clearance notch 44; the shape of the limiting protrusion 1123 matches the shape of the clearance notch 44. When the enclosure 43 is inserted into the second receiving cavity 112, the limiting protrusion 1123 is accommodated within the clearance notch 44. The alignment of the limiting protrusion 1123 with the clearance notch 44 makes it easier to confirm the placement direction of the sewage tank 4.

[0085] The second limiting protrusion 1124 is telescopically movably disposed on the limiting protrusion 1123 along the vertical direction of the floor brush mechanism 1, and the second limiting groove 45 is disposed on one side of the avoidance notch 44. Specifically, a second boss protrudes from the opening of the second accommodating cavity 112, the second boss is located on the side of the second accommodating cavity 112 near the clean water tank 3, and at least a portion of the second boss protrudes from the limiting protrusion 1123. The second boss is hollow, and a second opening is provided at the top of the second boss. The surface cleaning machine 100 also includes a second elastic member 52 disposed in the second boss, the two ends of the second elastic member 52 being respectively connected to the second boss and the second limiting protrusion 1124, so that the height of the second limiting protrusion 1124 extending out of the second opening can be adjusted. In this way, when the sewage tank 4 is placed in the second accommodating cavity 112, the second limiting protrusion 1124 can act as a buffer, preventing excessive impact on the floor brush mechanism 1 during placement. Furthermore, after the sewage tank 4 is in place, the elasticity of the second elastic member 52 ensures that the second limiting protrusion 1124 remains engaged with the second buckle 46 on the sewage tank 4, guaranteeing more reliable positioning of the sewage tank 4. The second buckle 46 is a limiting stop protrusion 461 located on the open side of the second limiting groove 45. The limiting stop protrusion 461 abuts against the side of the second limiting protrusion 1123 facing the clean water tank 3, preventing the sewage tank 4 from tilting forward and better ensuring its stability.

[0086] The first and second protrusions can be integrated into one unit, making the clean water tank 3 and the sewage tank 4 closer together and the structure more compact.

[0087] Moreover, combined Figure 7 and Figure 8 As shown, a sewage inlet 41 and an exhaust outlet 42 are provided at the bottom of the sewage tank 4, and a baffle 43 is provided around the outer periphery of the sewage inlet 41 and the exhaust outlet 42. At the bottom of the second accommodating cavity 112, a first pair of interfaces 1121 is provided opposite to the sewage inlet 41, and a second pair of interfaces 1122 is provided opposite to the exhaust outlet 42. The first pair of interfaces 1121 is connected to the suction port, and the second pair of interfaces 1122 is adapted to be connected to a suction device. When the suction device operates, a negative pressure is created inside the sewage tank 4, allowing sewage to enter the floor brush mechanism 1 from the suction port and flow from the first pair of interfaces 1121 to the sewage inlet 41, thus flowing into the sewage tank 4. The gas separated from the sewage tank 4 can flow through the exhaust outlet 42 to the second pair of interfaces 1122, and then through the second pair of interfaces 1122 to the suction device to be discharged from the floor brush mechanism 1, achieving airflow circulation for sewage suction.

[0088] Combination Figure 10As shown, this utility model also provides a surface cleaning system 1000, which includes the aforementioned surface cleaning machine 100 and a base 200, with the surface cleaning machine 100 placed on the base 200. Preferably, the surface cleaning machine 100 is detachably mounted on the base 200. This allows the surface cleaning machine 100 to rest on the base when not in operation, preventing it from sliding and ensuring greater stability. The base 200 may be provided with a groove that matches the shape of the bottom of the surface cleaning machine 100, allowing the bottom of the surface cleaning machine 100 to be better secured within the groove, further ensuring the stability of the surface cleaning machine 100.

[0089] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
