Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a charging component and a floor cleaning device. Background Technology

[0002] As people's quality of life continues to improve, more and more users are starting to use floor cleaning equipment to achieve automatic cleaning of their living or residential environments.

[0003] Floor cleaning equipment generally includes floor scrubbers and base stations. Floor scrubbers mainly consist of components such as floor brushes, a wastewater tank, a clean water tank, a motor, and a battery. The floor brushes include a roller brush, a water spray assembly, a squeegee, a suction channel, a roller brush motor, and a water pump. The water spray assembly draws water from the clean water tank and sprays it onto the roller brush, wetting it. The roller brush then rolls on the floor, achieving the effect of scrubbing and mopping. The squeegee scrapes off the wastewater, dust, and other debris from the roller brush. This scraped-off wastewater, dust, and debris falls near the suction channel and is sucked into the wastewater tank.

[0004] Base stations can be categorized by function into fully automatic base stations and push-in base stations. Fully automatic base stations require the floor scrubber to be lifted and lowered from above, allowing the drain outlet and charging terminals at the bottom of the scrubber to align with the base station. Push-in base stations allow the floor scrubber to be directly pushed into the base station from the ground.

[0005] Currently, most push-in base stations have their charging base located at the front of the main unit, and the electrode plates that connect to the main unit also need to be located at the lower front of the main unit. The scrubbing machine's connector shaft needs to be located at the lower rear of the main unit. This occupies both the front and rear space of the main unit's lower cover, making it impossible to install a drain outlet at the rear of the main unit's lower cover.

[0006] On the other hand, existing floor scrubbers typically have four charging electrodes on the bottom cover of the main unit. When the four charging electrodes are arranged side by side in front of or behind the bottom cover, they occupy a large area. This arrangement makes it impossible to install the drain outlet of the wastewater tank after the connector is installed on the bottom cover, or it is necessary to increase the thickness of the main unit to achieve the drain outlet. This results in the floor scrubber being too large in design size, which affects the user's experience. Utility Model Content

Detailed Implementation

[0061] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0062] The terminology used in the embodiments of this utility model is for the purpose of describing particular embodiments only and is not intended to limit the utility model. The singular forms “a,” “said,” and “the” used in the embodiments of this utility model and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise; “multiple” generally includes at least two, but does not exclude the inclusion of at least one.

[0063] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0064] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0065] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0066] As mentioned in the background section, most push-in base stations currently have their charging base located at the front of the main unit, and the electrode plates that connect to the main unit also need to be located at the lower front of the main unit. The scrubbing machine connector shaft needs to be located at the lower rear of the main unit. This occupies both the front and rear space of the main unit's lower cover, making it impossible to install a drain outlet at the rear of the main unit's lower cover.

[0067] On the other hand, the charging electrodes on the lower cover of the main unit of existing floor scrubbers are usually arranged in four parallel rows. The charging electrodes need to occupy a large area when placed in front of or behind the lower cover of the main unit. This arrangement makes it impossible to set the drain outlet of the wastewater tank after the connector is set on the lower cover, or it is necessary to increase the thickness of the main unit to set the drain outlet. This results in the design size of the floor scrubber being too large, which affects the user's experience.

[0068] Based on the technical problems in the background art mentioned above, such as Figures 1 to 13 As shown, an exemplary embodiment of the present invention provides a charging component 200. This charging component 200 can be applied to a floor cleaning device 100, wherein the floor cleaning device 100 may include a host 110 and a base station 120.

[0069] The main unit 110 may include a walk-behind floor scrubber, which may be a semi-automatic floor scrubber, a fully automatic floor scrubber, or a walk-behind floor scrubber, a rear-station floor scrubber, or a ride-on floor scrubber, or a smart floor scrubber with self-cleaning or high-temperature sterilization functions.

[0070] A floor scrubber also includes components such as a floor brush, a clean water tank, a waste water tank, a motor, and a battery. The floor brush comprises a roller brush, a water spray unit, a squeegee, a suction channel, a roller brush motor, and a water pump. The water spray unit draws cleaning water from the clean water tank and sprays it onto the roller brush, wetting it. The roller brush then rolls across the floor, achieving the effect of washing and mopping. The squeegee scrapes off the waste water, dust, and other debris from the roller brush. This scraped-off waste water, dust, and debris falls near the suction channel and is sucked into the waste water tank.

[0071] Base station 120 can use technologies such as laser or infrared to locate the floor scrubber. Through communication between the floor scrubber and the base station, the spatial location information of the floor scrubber can be accurately calculated, and the positioning function can realize real-time monitoring and remote operation of the floor scrubber.

[0072] When a floor scrubber is placed in a workplace, base station 120 can quickly plan the scrubbing route for the machine. Based on the ground conditions and defects, it can plan an optimal route for the machine, thereby greatly improving its scrubbing efficiency. The workplace can be the floor in a user's home, or in an office area, shopping mall, or other similar location.

[0073] Furthermore, base station 120 can also sense the surrounding environment and control the floor scrubber for obstacle avoidance. When the floor scrubber encounters obstacles, such as people or other objects, the base station can control the floor scrubber to stop or go around the obstacle, thereby ensuring the safety of personnel and the floor scrubber.

[0074] On the other hand, base station 120 can also charge the floor scrubber, provide a place for it, and treat the waste or wastewater generated during operation. It should be noted that the waste mentioned here can be solid waste or non-solid waste.

[0075] This example, and the examples below, use a walk-behind floor scrubber as an example.

[0076] like Figures 1 to 4 As shown, an arc-shaped connecting frame 123 is provided on the base station 120. An even number of snap-fit ​​protrusions 1231 are formed at the end of the arc-shaped connecting frame 123 away from the base station 120. There are two snap-fit ​​protrusions 1231. Specifically, a semi-annular connecting part is formed at the end of the arc-shaped connecting frame 123, and the opening of the semi-annular connecting part is set towards the pushing direction of the host 110.

[0077] The semi-circular connecting part can be used to connect with the connector adapter set on the host 110.

[0078] Two snap-fit ​​protrusions 1231 are respectively located at the two corners of the semi-circular connecting portion, and the two snap-fit ​​protrusions 1231 are symmetrically arranged along the axis of the base station 120. Each snap-fit ​​protrusion 1231 has an upward-facing receiving cavity, in which the snap-fit ​​groove 121 and the fixing member 122 are both disposed.

[0079] The charging assembly 200 includes a charging base 210 and a charging body 220.

[0080] There are two charging bases 210, and they are arranged one-to-one in the receiving cavity, for example, in an embedded manner.

[0081] The number of charging bodies 220 is the same as the number of charging bases 210, and the charging bodies 220 are mounted on the host 110.

[0082] When the host 110 is placed in the charging position on the base station 120, the charging body 223 contacts the charging base 210 to charge the host 110, for example, to charge the battery module inside the host 110.

[0083] In this example, the charging base 210 is symmetrically arranged on the base station 120 using the symmetrically arranged snap-fit ​​protrusions 1231, and the host 110 is charged through the contact between the charging base 210 and the charging body 220. This effectively simplifies the structure of the ground cleaning equipment 100 and ensures and improves the assembly efficiency of the equipment.

[0084] It should be noted that in this example, there are two charging bases 210 and two charging bodies 220, and each charging base 210 has two symmetrically arranged charging electrodes 211. That is to say, there are four charging electrodes 211 and four contact electrodes 221.

[0085] like Figures 1 to 13 As shown, the charging base 210 is embedded in the base station 120, and a charging electrode 211 is provided inside the charging base 210. The number of charging electrodes 211 can be one or more.

[0086] The charging body 220 is mounted on the host 110, and contact electrodes 221 are provided on the charging body 220. The number of contact electrodes 221 is the same as the number of charging electrodes 211, and they are arranged in a one-to-one correspondence.

[0087] When the host 110 is placed on the charging position of the base station 120, the contact electrode 221 will press the corresponding charging electrode 211, so that the charging electrode 211 can produce elastic deformation. The other end of the charging electrode 211 is electrically connected to the charging power supply. Based on this, the host 110 is charged through the contact electrode 221 and the charging electrode 211.

[0088] In this example, when the host 110 needs to be charged, it is placed on the base station 120. At this time, the contact electrode 221 presses the charging electrode 211 so that the host 110 is charged after the charging electrode 211 undergoes elastic deformation. This can effectively solve the problem of the fit gap when the host 110 is connected to the base station 120 for charging, and also make the structure of the host 110 simpler in design, thus ensuring and improving the assembly efficiency of the ground cleaning equipment 100.

[0089] like Figures 1 to 7 As shown, in some embodiments, the charging dock 210 includes a hollow first support 212, on which an opening 213 is provided, the opening 213 being oriented toward the direction in which the host 110 detaches from the base station 120.

[0090] The first bracket 212 has a hollow structure, forming an internal space. This space provides a place for other components, such as the charging contacts 211 or snap-fit ​​protrusions, while maintaining a neat and aesthetically pleasing appearance. Furthermore, the hollow structure of the first bracket 212 enhances the heat dissipation performance of the charging base 210, preventing damage to the charging contacts 211 due to heat accumulation during charging.

[0091] The opening 213 is located at the top or side top of the first support 212 to facilitate contact between the charging electrode 211 and the contact electrode 221 at the opening 213. Simultaneously, the structural design of the opening 213 also facilitates communication between the interior of the hollow first support 212 and the outside, ensuring the thermal stability of the first support 212, thereby effectively guaranteeing and improving the stability of the contact between the charging electrode 211 and the contact electrode 221 during charging.

[0092] The charging electrode 211 includes a fixed end 2111 and a flexible charging end 2112 that are easily connected. The fixed end 2111 is fixedly connected to the first bracket 212 and serves as a support base for the charging electrode 211, ensuring the structural stability of the entire charging electrode 211 during charging. An electrical connection hole 2113 is provided on the fixed end 2111 at a position away from the flexible charging end 2112, and this electrical connection hole 2113 is used to connect the power cord of the charging power supply.

[0093] The flexible charging terminal 2112 is arranged at the opening 213. It should be noted that the flexible charging terminal 2112 can be bent within a certain range to adapt to openings 213 of different structures and sizes, as well as to contact plates 221 of different structures or shapes, to ensure the stability of the contact between the charging plate 211 and the contact plate 221 during charging.

[0094] During the charging process, the elastic charging end 2112 abuts against the contact electrode 221, and the contact electrode 221 presses the elastic charging end 2112, so that the elastic charging end 2112 undergoes elastic deformation. This effectively solves the problem of the fit gap that occurs when the host 110 and the base station 120 are connected and charged, and also makes the host structure simpler to design.

[0095] like Figures 1 to 13 As shown, in some embodiments, a limiting part 213a is provided at the rear end of the opening 213 of the first bracket 212, and the end of the elastic charging end 2112 abuts against the inner sidewall of the limiting part 213a, so as to restrict the end of the elastic charging end 2112 from extending upward by the limiting part 213a, ensuring that the elastic charging end 2112 can always be in the predetermined position, which can effectively avoid misalignment or damage caused by accidental impact or other external forces.

[0096] A guide portion 213b is provided at the front end of the opening 213. The guide portion 213b has a first end and a second end that are connected, with the second end located near the limiting portion 213a. The horizontal position of the first end is lower than that of the second end, so that the guide portion 213b forms an inclined structure, so that when the host 110 is pushed into the base station 120, the guide portion 213b provides a guiding channel for the multiple contact electrodes 221.

[0097] like Figures 1 to 13 As shown, in some embodiments, a first locking protrusion 214, a second locking protrusion 215, and a third locking protrusion 216 are provided at intervals within the first bracket 212. The two ends of the first locking protrusion 214, the second locking protrusion 215, and the third locking protrusion 216 are respectively connected to two opposite sidewalls within the first bracket 212 to ensure and improve the structural stability of the first bracket 212.

[0098] The first snap-fit ​​protrusion 214 and the second snap-fit ​​protrusion 215 are arranged in parallel to form a transverse basic support frame structure, which ensures the stability of the contact between the fixed end 2111 and the first snap-fit ​​protrusion 214 and the second snap-fit ​​protrusion 215 when the fixed end 2111 is located on the upper surface of the first snap-fit ​​protrusion 214 and the second snap-fit ​​protrusion 215. At the same time, it also helps to disperse the contact stress between the fixed end 2111 and the first snap-fit ​​protrusion 214 and the second snap-fit ​​protrusion 215, prevents local overload of the fixed end 2111, and thus ensures the reliability of the fixed end 2111 during assembly.

[0099] Unlike the first latching protrusion 214 and the second latching protrusion 215, the third latching protrusion 216 is located at the center above the first latching protrusion 214 and the second latching protrusion 215.

[0100] Among them, a fixed gap is formed between the bottom surface of the third snap-fit ​​protrusion 216 and the top surface of the first snap-fit ​​protrusion 214 and the second snap-fit ​​protrusion 215, and the fixed end 2111 is inserted into the fixed gap, thereby realizing a stable connection between the fixed end 2111 and the first snap-fit ​​protrusion 214, the second snap-fit ​​protrusion 215 and the third snap-fit ​​protrusion 216.

[0101] When the fixed end 2111 is placed into the fixed gap, it will be locked by the fixed gap formed by the first locking protrusion 214, the second locking protrusion 215 and the third locking protrusion 216, and will not easily slide or fall off, forming a stable connection and fixing structure.

[0102] like Figures 1 to 13 As shown, in some embodiments, in order to improve the assembly efficiency and connection stability between the first bracket 212 and the base station 120, a buckle 217 is provided on the front side wall of the first bracket 212, and a slot 121 is provided on the base station 120 at a position opposite to the buckle 217.

[0103] The latch 217 is a protruding structure located on the front side wall of the first bracket 212. The latch 217 can have a certain degree of elasticity, and can quickly lock or release the first bracket 212 and the base station 120 through slight pressure or pushing and pulling actions. The front end of the latch 217 can be designed with an inclined guide slope to facilitate smooth insertion into the latch slot 121 during docking, forming a mechanical interlocking structure.

[0104] A fixing part 218 is provided on the rear side wall of the first bracket 212, and a fixing member 122 is provided on the base station 120 at a position opposite to the fixing part 218.

[0105] The use of the fixing part 218 and the fixing member 122 together can realize the fixed connection of the first bracket 212. With the snapping action of the buckle 217 and the slot 121, the first bracket 212 is double locked, thereby improving the stability of the connection of the first bracket 212.

[0106] like Figures 1 to 13 As shown, in some embodiments, the bottom side of the fixing part 218 is provided with a slot 218a facing the bottom of the base station 120, wherein the slot 218a is sleeved on the fixing member 122.

[0107] In one example, the slot 218a has a connecting hole, and the fastener 122 has a through hole. After the first bracket 212 is placed in place, the through hole and the connecting hole are connected by fastening bolts, thereby realizing a detachable connection between the fixing part 218 and the fastener 122.

[0108] like Figures 1 to 13As shown, in some embodiments, each first bracket 212 is provided with two symmetrically arranged charging electrodes 211.

[0109] The first bracket 212 includes two symmetrically arranged accommodating spaces, each of which is provided with a first snap-fit ​​protrusion 214, a second snap-fit ​​protrusion 215, and a third snap-fit ​​protrusion 216. Two charging electrodes 211 are respectively disposed in the open openings 213 provided on the front top side of the two accommodating spaces.

[0110] Correspondingly, each charging element 220 is provided with two contact electrodes 221.

[0111] In this example, two charging electrodes 211 are provided in the first bracket 212, and two contact electrodes 221 are provided in the charging body 220 accordingly, so as to meet the charging speed and charging requirements of the host 110.

[0112] like Figures 6 to 13 As shown, in some embodiments, a detachable lower cover 111 is provided at the lower end of the main unit 110, and at least one through hole 112 is formed on the lower cover 111.

[0113] The charging body 220 includes a second bracket 222, which is mounted on the lower cover 111 and located inside the main unit 110. One side wall of the second bracket 222 has a connecting buckle, which allows for a snap-fit ​​connection between the second bracket 222 and the lower cover 111. The other side wall of the second bracket 222 has a screw hole, which allows for a fixed connection between the second bracket 222 and the lower cover 111 using screws.

[0114] The contact electrode 221 is fixed on the second bracket 222. The end of the contact electrode 221 facing away from the main unit 110 has a contact portion 221a. The contact portion 221a passes through the through hole 112 and extends out of the lower cover 111 by a predetermined distance.

[0115] When the host 110 is placed in the charging position of the base station 120, the contact part 221a presses the charging electrode 211 to cause the charging electrode 211 to undergo elastic deformation and charge the host 110.

[0116] Specifically, the contact portion 221a can contact the elastic charging terminal 2112. When the host 110 is placed in the charging position of the base station 120, the contact portion 221a presses the elastic charging terminal 2112 to cause the elastic charging terminal 2112 to undergo elastic deformation, thereby realizing the charging of the host 110.

[0117] In this configuration, along the top-to-bottom direction, i.e., along the height of the base station 120, the contact portion 221a is located at the lower part of the contact electrode 221, and the upper part of the contact electrode 221 is provided with a wire through hole 221b. The wire through hole 221b is used for soldering wires, which can be connected to the battery module in the host 110. When the host 110 is placed in the charging position of the base station 120, the contact portion 221a presses against the elastic charging terminal 2112, causing the elastic charging terminal 2112 to undergo elastic deformation, thereby enabling the charging of the battery module of the host 110.

[0118] like Figures 6 to 8 As shown, in some embodiments, the lower cover 111 is provided with a plurality of limiting protrusions 113. The limiting protrusions 113 are located on each side wall of the charging electrode 211 and are used to limit the charging electrode 211.

[0119] Specifically, the length of the contact portion 221a is less than the length of the main body of the contact electrode 221. This design allows the contact portion 221a to extend out of the through hole 112 and form a snap-fit ​​design between the main body of the contact electrode 221 and the lower cover 111. At the same time, multiple limiting protrusions 113 limit the side walls of the main body of the charging electrode 211. On the other hand, the second bracket 222 fixes the top surface of the charging electrode 211. Based on this, the contact electrode 221 can be effectively and firmly fixed on the lower cover 111.

[0120] like Figures 1 to 13 As shown, an exemplary embodiment of the present invention provides a ground cleaning device, including: a base station 120, a floor brush assembly, and a charging assembly 200 of any of the above embodiments.

[0121] The charging base 210 in the charging component 200 is mounted on the arc-shaped connecting frame 123 of the base station 120, and the base station 120 is provided with a wheel groove 124.

[0122] The floor brush assembly includes a main unit 110 and a floor brush body 130. The main unit 110 includes a body 114 and a lower cover 111. The lower cover 111 is provided with a drain clearance groove 115 and a connection hole 116 for connecting to the floor brush body 130. The drain clearance groove 115 can be connected to the drain outlet of the wastewater tank, and the connection hole 116 can realize the connection between the floor brush body 130 and the connector on the main unit 110.

[0123] The charging body 220 in the charging assembly 200 is disposed on the lower cover 111 and located inside the host 110. When the ground brush assembly is pushed into the charging position of the base station 120, the walking wheel in the ground brush body is located in the wheel groove 124, and the contact electrode 221 in the charging body 220 presses the charging electrode 211 in the charging base 210 so that the battery module in the host 110 is charged after the charging electrode 211 undergoes elastic deformation.

[0124] The charging assembly 200 has two charging bases 210 and two charging bodies 220. The connection hole 116 and the drain clearance groove 115 are coaxially arranged and located in the middle of the two charging bodies 220.

[0125] In this example, two sets of charging electrodes 211 are symmetrically arranged at the bottom of the lower cover 111 of the host 110, with two electrodes in each set. The four charging electrodes 211 are located at the lower front of the connection hole 116 of the lower cover 111, and the sewage discharge clearance groove is located at the lower rear of the connection hole 116 of the lower cover 111. Based on this, the host 110 in this example can be connected to various charging base stations without increasing the thickness of the body, thus improving the applicability of the host 110. At the same time, by integrating the two charging bodies 220, the connector of the host 110, and the sewage discharge clearance groove of the sewage tank onto the lower cover 111, the overall structural layout of the host 110 is more reasonable, effectively solving the problem that fully automatic base stations and push-in base stations cannot share the host 110 in the prior art.

[0126] On the other hand, the charging electrode 211 in the charging base 210 adopts an elastic electrode sheet, which can maintain a good contact state between the charging electrode 211 and the contact electrode 221 without adding additional elastic parts. At the same time, it can effectively simplify the structural design of the entire charging assembly 200 and effectively improve the assembly efficiency of the entire ground cleaning equipment 100.

[0127] In use, the user can push the main unit 110 to the charging position of the base station 120 using the wheeled structure. When the wheeled structure moves into the wheel groove 117, the connector between the main unit 110 and the ground brush assembly matches the arc-shaped connecting frame 123. Then, the user continues to push the main unit 110 to rotate along the arc-shaped trajectory, using the ground brush assembly as the rotation point, until the charging body 220 and the charging base 210 are connected. At this time, the contact electrode 221 on the charging body 220 presses the charging electrode 211 on the charging base 210, causing the charging electrode 211 to undergo elastic deformation, thereby charging the battery module in the main unit 110.
