Description

Cleaning equipment and liquid level detection components Technical Field

[0001] This application relates to the field of cleaning equipment technology, specifically to a cleaning device and a liquid level detection component. Background Technology

[0002] Cleaning equipment such as floor scrubbers typically includes a storage container for liquids. For example, after a floor scrubber has been used, it will generate wastewater, so a wastewater tank (also called a recycling bin) is installed to store the wastewater generated during cleaning. When the liquid level in the wastewater tank reaches a certain height, the tank needs to be cleaned.

[0003] Typically, existing technologies use liquid level detection probes to detect the liquid level in wastewater tanks. However, the shape, size, and other parameters of liquid level conductive probes are fixed, resulting in poor applicability. If the structure of a floor scrubber or other cleaning equipment changes, the shape, size, and other parameters of the liquid level detection probe also need to be changed accordingly. This requires the creation of new production molds for the liquid level detection probes, which is costly. Summary of the Invention

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0037] This application provides a cleaning device and a liquid level detection component, which are described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, in the following embodiments, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments. Unless otherwise explicitly stated or without any obstacles to combination in this application, the parts described in the various embodiments can be combined with each other, and the examples in this embodiment do not constitute an undue limitation on such combinations.

[0038] The embodiments of this application provide a cleaning device, which may be a handheld vacuum cleaner, floor scrubber, carpet cleaner, desktop cleaner, cleaning robot, or other devices used for cleaning, etc., and this embodiment does not limit it.

[0039] Please refer to Figure 1. The cleaning equipment mainly includes a body 10, a liquid storage container 20, and a liquid level detection component 30 (see Figure 5).

[0040] Referring to Figure 1, the body 10 roughly forms the main structural outline of the cleaning device and can be used to install, support, and connect other components. Exemplarily, the body 10 includes a main body 11, and a handle 12, a suction source, a power supply assembly, a cleaning head 13, a controller, etc., mounted on the main body 11. The handle 12 is used by the user to operate the cleaning device. The suction source, power supply assembly, cleaning head 13, controller, or other components can be mounted on the handle 12. Here, the cleaning head 13 is located at the bottom of the handle, and the power supply assembly can be located slightly lower on the handle to lower the overall center of gravity of the device; however, this embodiment does not limit this. Here, the controller includes chips, circuits, and other structures, which can connect to other components to control them. The power supply assembly is used to connect to and supply power to components that require power. For example, the power supply assembly, controller, cleaning head 13, and suction source are connected. The cleaning head 13 has a cleaning chamber and is equipped with a rotating body such as a roller brush. The controller can control the rotation of the rotating body of the cleaning head 13 and control the suction source to operate to form a suction airflow, thereby achieving cleaning of the surface to be cleaned. It is understood that in other embodiments, the cleaning device can be a self-moving device such as a cleaning robot. In this case, the body 10 includes the shell structure of the cleaning robot and corresponding components on the shell structure. Of course, the above examples of this embodiment do not constitute an undue limitation on this application.

[0041] The liquid storage container 20 is disposed on the body 10 and has a receiving space for storing liquids used for cleaning the equipment or liquids generated or absorbed by the cleaning equipment. Typically, the liquid storage container 20 is detachably mounted on the body 10 (e.g., by snap-fit ​​connection) for disassembly and cleaning / / or liquid replenishment, but this embodiment is not limited to this. For example, in one example, the liquid storage container 20 is used to store clean water or cleaning fluid, which is supplied to the cleaning chamber of the cleaning equipment or to the surface to be cleaned, thereby achieving better cleaning of the surface. As another example, in another example, the liquid storage container 20 is used to store wastewater generated after the cleaning equipment has operated; the wastewater from the surface to be cleaned and / or the cleaning chamber is drawn into the liquid storage container 20. The liquid storage container 20 supplies the liquid inside to a designated location through a pipeline and a suction device such as a motor configured in the pipeline. The suction device such as the motor and the suction source used to form the suction airflow can be the same component. Of course, in some embodiments, the suction device such as the motor and the suction source used to form the suction airflow can be different components. The example in this embodiment does not constitute an undue limitation.

[0042] In some embodiments, referring to FIG2, the liquid storage container 20 includes a container body 21 and a cap 22, the container body 21 having the aforementioned receiving space. Typically, an opening is provided on one vertical side of the receiving space, and the cap 22 is operably fitted onto the container body 21 to close or open the opening. Exemplarily, the cap 22 can snap onto the opening. Referring to FIGS. 3 and 4, they show schematic diagrams of the cap 22 after being removed from the container body 21. In other embodiments, the cap 22 may also be pivotally attached to one side of the opening, magnetically fitted at the opening, or otherwise operably fitted at the opening; the examples in this embodiment do not constitute undue limitation.

[0043] In a further embodiment, referring to FIG2, the cover 22 is provided with a receiving shell 221 extending toward the container body 21, and the inner cavity of the receiving shell 221 is used to accommodate at least a portion of the liquid level detection component. Exemplarily, when two liquid level detection components are provided, the cover 22 may be provided with two spaced-apart receiving shells 221 to accommodate at least a portion of each of the two liquid level detection components. Here, the receiving shell 221 and the cover 22 may be integrally formed, or the receiving shell 221 may be separately connected to the cover 22; this embodiment does not impose any limitations.

[0044] Furthermore, it is understood that in Figure 2, in order to show the structure inside the container body 21, part of the outer wall of the container body 21 has been removed so as to show the internal accommodating space and accommodating shell 221, but in the actual product, the container body 21 usually has a complete outer wall to form the accommodating space.

[0045] Furthermore, this embodiment is merely an illustrative example of the structure of the liquid storage container 20. In other embodiments, the structure of the liquid storage container 20 may also be different. For example, the cover 22 may be located on the side or other position of the container body 21. Alternatively, the liquid storage container 20 may not have a cover 22 and may be a generally closed structure that is integral with a channel for water inlet and outlet. The example in this embodiment does not constitute an undue limitation on the structure and shape of the liquid storage container 20.

[0046] The liquid level detection component 30 is used to detect the liquid level in the storage container 20 in order to realize related functions. These related functions may include providing prompts to the user, performing related operations, or other functions; this embodiment does not limit these functions.

[0047] Please refer to Figure 5 here. The liquid level detection component 30 includes a conductive connector 31, a flexible conductive component 32, and a conductive detection component 33.

[0048] Referring to Figures 3 and 4, the conductive connector 31 is disposed on the liquid storage container 20 for coupling with the body 10 (see Figure 1) and transmitting electrical signals. Exemplarily, the conductive connector 31 is disposed on the cover 22 of the liquid storage container 20, located on the side of the cover 22 away from the container body 21, so that when the liquid storage container 20 is assembled onto the body 10, the conductive connector 31 can be coupled to a corresponding part on the body 10. Specifically, the conductive connector 31 can be coupled to the controller of the body 10, for example, to the detection circuit of the controller. In a further example, a contact is provided on the body 10 corresponding to the position of the conductive connector 31. When the liquid storage container 20 is assembled onto the body 10, the conductive connector 31 contacts the contact to form an electrical connection. The contact is disposed in the detection circuit of the controller, thereby coupling the conductive connector 31 to the controller. Of course, in other embodiments, the location of the conductive connector 31 may be different, and the coupling method between the conductive connector 31 and the body 10 may also be different. The example in this embodiment does not constitute an undue limitation.

[0049] Referring again to Figure 5, the flexible conductive element 32 is connected to the conductive connector 31 and the conductive detection element 33, and is used to realize the electrical connection between the conductive connector 31 and the conductive detection element 33. Here, the flexible conductive element 32 can be a wire, a flexible printed circuit (FPC), or other flexible conductive components. The flexible conductive element 32 can be bent, folded, or wrapped, etc., so as to adapt to different sizes and application space requirements. Furthermore, it can be conveniently connected to the conductive connector 31 and the conductive detection element 33 by welding or other means, so that the conductive connector 31 of appropriate size can be selected according to actual needs.

[0050] The conductive detection element 33 is at least partially located within the containment space for detecting the liquid level in the containment space. Here, the conductive detection element 33 is coupled to the controller via a flexible conductive element 32 and a conductive connector 31, so that the detection signal can be transmitted to the controller of the body 10.

[0051] In some embodiments, the conductive detection element 33 may be made of a non-metallic conductive material. This is because the conductive detection element 33 needs to be in contact with the liquid in the storage container 20 to detect the liquid level, and when the conductive detection element 33 is in contact with the liquid for a long time, it is prone to oxidation, rusting, and other problems. In the embodiments of this application, the conductive detection element 33 is made of a non-metallic conductive material, thereby reducing the risk of rusting. For example, the non-metallic conductive material is graphite, selenium, or silicon. Of course, it is understood that in other embodiments, the non-metallic conductive material is not limited to the above, or the conductive detection element 33 may also be made of a metallic material, which can also achieve the technical effect of liquid level detection. The example of this embodiment does not constitute an undue limitation.

[0052] Here, the resistance of the sequentially connected conductive connector 31, flexible conductive element 32, and conductive detection element 33 is relatively small. For example, in one example, when the conductive detection element 33 is made of graphite, the overall resistance of the sequentially connected conductive connector 31, flexible conductive element 32, and conductive detection element 33 is 2-6 ohms. The inventors of this application are aware of a liquid level detection component that uses a carbon fiber-doped injection molded part to form a rigid conductive structure, and a metal sheet is placed on the injection molded part as a detection component. When electrical conduction is formed between the injection molded part and the metal sheet and the controller, its resistance is approximately 30-40 ohms. Therefore, the liquid level detection component provided in this application helps to reduce the conduction resistance of the liquid level detection component, thereby making the liquid level detection more sensitive and effective.

[0053] In some embodiments, referring to Figure 5, the liquid level detection assembly 30 further includes a housing 34. The conductive detection element 33 is fixed inside the housing 34. The housing 34 has an exposure opening 341 to expose at least a portion of the conductive detection element 33, allowing it to contact the liquid outside and perform the detection function. Exemplarily, the conductive detection element 33 is fixed inside the housing 34 by potting adhesive, i.e., the conductive detection element 33 is glued inside the housing 34, and an adhesive layer is formed between the conductive detection element 33 and the housing 34. This fixing method is simple to operate, easy to implement, and low in cost. It eliminates the need for complex connection structures and also provides insulation, sealing, and moisture protection, making it particularly suitable for conductive detection elements 33 made of non-metallic conductive materials. As another example, the liquid level detection assembly 30 further includes a first sealing element, which is interference-fitted between the housing 34 and the conductive detection element 33 to fix the conductive detection element 33. The first sealing element can be a sealing ring, etc. In other embodiments, the conductive detection element 33 and the housing 34 may also be fixedly connected by different means such as snap-fit, Velcro, or other methods. The examples in this embodiment do not constitute an undue limitation.

[0054] The housing 34 can be used to protect the conductive detection element 33, and / or the housing 34 can be provided with an assembly structure to assemble the housing 34 and the conductive detection element 33 into the liquid storage container 20. Exemplarily, in some embodiments, referring to Figures 6 and 7, the housing 34 is provided with a snap-fit ​​groove 342. Here, the housing 34 is provided with a flange 343 protruding outward in a circumferential direction and a plurality of snap-fit ​​portions 344 protruding outward in a circumferential direction. The flange 343 and the snap-fit ​​portions 344 are spaced apart along the length of the housing 34 to form the snap-fit ​​groove 342. Here, the number of snap-fit ​​portions 344 is two. In other embodiments, the number of snap-fit ​​portions 344 may also be different, and this embodiment does not limit it.

[0055] Please refer to Figure 5. Here, in some embodiments, the liquid storage container 20 includes a cover 22, on which a receiving shell 221 is provided. At least a portion of the housing 34 and the flexible conductive element 32 are housed within the receiving shell 221. The receiving shell 221 has a protruding snap-fit ​​protrusion 222 on its inward side. The snap-fit ​​protrusion 222 is correspondingly provided with the snap-fit ​​groove 342. The two can cooperate with each other to fix the housing 34 and the conductive detection element 33 to the receiving shell 221, that is, to the liquid storage container 20.

[0056] It is understood that in other embodiments, a snap-fit ​​groove 342 may be provided on the housing 221, and a snap-fit ​​protrusion 222 may be provided on the housing 34 accordingly. In addition, the snap-fit ​​groove 342 or the snap-fit ​​protrusion 222 may not be provided on the housing 221, but on other parts of the liquid storage container 20, as long as the housing 34 can be fixed to the liquid storage container 20. Furthermore, the matching connection method between the housing 34 and the housing 221 is not limited to the above. For example, the two can be glued or welded. The example of this embodiment does not constitute an improper limitation.

[0057] In a further embodiment, in addition to the housing 34 being fixed within the receiving shell 221, the housing 34 is further provided with a mating groove for embedding a second sealing ring, which can improve the sealing performance between the receiving shell 221 and the housing 34. It is understood that in other embodiments, the mating groove may also be located on the inner side of the receiving shell 221, and this embodiment does not limit this.

[0058] In addition, in some embodiments, please continue to refer to FIG5, the end of the housing 34 away from the conductive connector 31 is provided with an adhesive layer 345, which helps to achieve the insulation, moisture-proof and other effects.

[0059] As can be seen, in the embodiments provided in this application, the conductive detection element 33 is connected to the conductive connector 31 via a flexible conductive element 32, and then coupled to the body 10 via the conductive connector 31. The conductive detection element 33 and the conductive connector 31 are connected by a flexible conductive element 32, which can be bent, wound, or otherwise altered to change its length according to actual needs. Therefore, the liquid level detection component 30 can be applied to liquid storage containers 20 of different sizes. This eliminates the need to set different sizes of liquid level detection components 30 for liquid storage containers 20 of different shapes and sizes, reducing production and usage costs.

[0060] Furthermore, in the embodiments of this application, this setting enables modular design of each component. The conductive connector 31, flexible conductive component 32, and conductive detection component 33 are no longer a rigid structure connected as a whole. Each component can be manufactured separately, and a flexible conductive component 32 of appropriate length and size can be selected according to actual needs to better meet the requirements of actual spatial layout.

[0061] In some embodiments, please refer to FIG5. The liquid level detection component 30 further includes a conductive elastic element 35. When the conductive connector 31 is connected to the liquid storage container 20 (e.g., the cover 22 of the liquid storage container 20), the conductive elastic element 35 is disposed between the flexible conductive element 32 and the conductive connector 31 and is in a compressed state to form an electrical connection between the flexible conductive element 32 and the conductive connector 31.

[0062] For example, the conductive elastic element 35 is a spring. Of course, in other embodiments, the conductive elastic element 35 can also be a sheet or other elastic body. Typically, the conductive elastic element is made of metal to achieve the function of conduction, but this embodiment does not limit it. Here, the liquid storage container 20 is provided with two connecting parts, and the conductive connector 31 is connected to the connecting parts. For example, the conductive connector 31 is a sheet-like metal component, and the connecting part is an opening or groove. The edge of the sheet-like metal component is bent and embedded in the opening or groove to realize the connection between the conductive connector 31 and the liquid storage container 20. Alternatively, the conductive connector 31 can also be connected to the liquid storage container 20 in other ways, such as being fixed to the cover 22 of the liquid storage container 20 by screws.

[0063] Here, the conductive elastic element 35 includes a fixed end and a free end. The fixed end is disposed on the liquid storage container 20. For example, a connecting post is provided on the cover 22 of the liquid storage container 20. The connecting post has a circumferentially protruding portion at the end away from the conductive connector 31. The conductive elastic element 35 can be sleeved on the connecting post, and the fixed end can abut against and / or connect to the protruding portion. The free end corresponds to the position of the connecting portion. When the conductive connector 31 is installed in the position of the connecting portion, the conductive connector 31 presses against the free end, so that the conductive elastic element 35 is in a compressed state. When the conductive connector 31 is not installed, the conductive elastic element 35 is in an uncompressed state and will protrude towards the connecting portion compared to the compressed state.

[0064] Therefore, when the conductive connector 31 is installed in place, the conductive elastic element 35 is compressed by the conductive connector 31, thus ensuring contact between the conductive connector 31 and the conductive elastic element 35, thereby achieving electrical conductivity between them. Simultaneously, the conductive elastic element 35 is connected to the flexible conductive element 32, thus achieving electrical conductivity between the conductive detection element 33, the flexible conductive element 32, and the conductive connector 31. That is, this arrangement reduces the possibility of connection failure between the conductive connector 31 and the flexible conductive element 32, thereby improving the effectiveness of the liquid level detection assembly 30.

[0065] In some embodiments, the cleaning equipment is equipped with two sets of liquid level detection components 30. When the liquid level in the storage container 20 reaches a preset liquid level height, the conductive detection elements 33 of both sets of liquid level detection components 30 come into contact with the liquid, and the circuit is connected by the liquid. That is, after the electrical signal is sent by the controller, it passes sequentially through the conductive connector 31, flexible conductive element 32, and conductive detection element 33 of the first set of liquid level detection components 30, and is transmitted to the conductive detection element 33 of the second set of liquid level detection components 30 via the liquid. Then, the electrical signal passes sequentially through the flexible conductive element 32 and conductive connector 31 of the second set of liquid level detection components 30 and is transmitted to the controller, thereby forming a closed circuit. Thus, the controller recognizes that the liquid level in the storage container 20 has reached the preset liquid level height, thereby controlling the cleaning equipment to stop and / or issuing a prompt signal to the user, etc.

[0066] It is understood that in other embodiments, the potential difference between the conductive connectors 31 of the two sets of liquid level detection components 30 can also be used to determine whether the liquid has reached the preset liquid level height. For example, if one conductive connector 31 is grounded, the controller detects that the voltage of this conductive connector 31 is zero. At this time, if the other conductive connector 31 is not grounded, the controller detects that the voltage of this other conductive connector 31 is greater than zero, thus forming a voltage difference between the two conductive connectors 31. When the conductive detection element 33 comes into contact with the liquid, this voltage difference will change, and the controller compares this voltage difference with a preset standard value to determine whether the liquid has reached the preset liquid level height.

[0067] Accordingly, in order to better achieve the technical effects of the embodiments of this application, the embodiments of this application also provide a liquid level detection component 30, which can be used in cleaning equipment or other equipment to detect the liquid level height.

[0068] Here, the liquid level detection assembly 30 includes a conductive connector 31, a flexible conductive element 32, and a conductive detection element 33. The conductive connector 31 is disposed on the liquid storage container 20 and is used for coupling to an external circuit; the flexible conductive element 32 is connected to the conductive connector 31; and the conductive detection element 33 is connected to the flexible conductive element 32.

[0069] In some embodiments, the conductive detection element 33 is made of a non-metallic conductive material.

[0070] In some embodiments, the non-metallic conductive material is one of graphite, selenium, or silicon. It is understood that the non-metallic conductive material is not limited to the materials mentioned above.

[0071] In some embodiments, the liquid level detection assembly 30 further includes a housing 34, the conductive detection element 33 is fixed inside the housing 34, and the housing 34 is provided with an exposure opening 341 to expose a portion of the conductive detection element 33.

[0072] In some embodiments, an adhesive layer is provided inside the housing 34, and the conductive detection element 33 is fixedly connected to the housing 34 through the adhesive layer; or, the liquid level detection assembly 30 further includes a first sealing element, which is interference-fitted between the housing 34 and the conductive detection element 33 to fix the conductive detection element 33.

[0073] In some embodiments, the flexible conductive element 32 is a flexible circuit board or a wire.

[0074] In some embodiments, the liquid level detection assembly 30 further includes a conductive elastic element 35, which is disposed between the flexible conductive element 32 and the conductive connector 31 and is in a compressed state to form an electrical connection between the flexible conductive element 32 and the conductive connector 31.

[0075] Application Example 1

[0076] In application example one, a liquid level detection component 30 is provided, which includes a conductive connector 31, a flexible conductive element 32, and a conductive detection element 33. The conductive connector 31 is coupled to a controller, for example, to a controller on the body 10 of a cleaning device. The flexible conductive element 32 is connected to the conductive connector 31, and the conductive detection element 33 is connected to the flexible conductive element 32. The flexible conductive element 32 is a wire or a flexible circuit board.

[0077] Application Example 2

[0078] In application example two, a liquid level detection component 30 is provided, which has a structure largely the same as that in application example one. The difference is that the conductive detection element 33 is made of a non-metallic conductive material. Specifically, it can be made of graphite, and the conductive detection element 33 is generally cylindrical.

[0079] Application Example 3

[0080] In application example three, a liquid level detection component 30 is provided, which has a structure largely the same as that in application example two. The difference is that the liquid level detection component 30 further includes a housing 34, and the conductive detection element 33 is fixed inside the housing 34 by potting adhesive. The housing 34 has an exposure opening 341 on one side corresponding to the conductive detection element 33 to expose a portion of the surface of the conductive detection element 33.

[0081] Application Example 4

[0082] In Application Example 4, a liquid level detection assembly 30 is provided, which is substantially the same in structure as that in Application Example 2 or 3. The difference lies in that the liquid level detection assembly 30 further includes a conductive elastic element 35, which is a spring. The spring is fixed to an external component not belonging to the liquid level detection assembly 30, and the conductive detection element 33 is connected to the spring via a flexible conductive element 32. When the conductive connector 31 is connected to the external component, the conductive connector 31 compresses the spring, causing the spring to be compressed away from the conductive connector 31. Therefore, in the state after the conductive connector 31 is installed, the spring has a tendency to extend towards the conductive connector 31, so that the spring can maintain contact with the conductive connector 31, thereby achieving an electrical connection between the flexible conductive element 32 and the conductive connector 31.

[0083] For example, the external component is a liquid storage container 20 of a cleaning device, a spring is fixed to the liquid storage container 20, and a conductive connector 31 is installed on the liquid storage container 20.

[0084] Application Example 5

[0085] In application example five, a cleaning device, a floor scrubber, is provided. The floor scrubber has a liquid storage container 20, which serves as the wastewater tank for the floor scrubber. Two sets of liquid level detection components 30, provided in any of application examples one through four, are disposed at the liquid storage container 20. The conductive sensing element 33 of the liquid level detection component 30 extends into the liquid storage container 20 to detect the liquid level therein.

[0086] Application Example Six

[0087] In application example six, a cleaning device is provided, which is a washing and mopping robot. The washing and mopping robot has a liquid storage container 20, which is the clean water tank of the washing and mopping robot, used to store water or other cleaning solutions. Two sets of liquid level detection components 30 provided in any of application examples one to four are disposed at the liquid storage container 20. The conductive detection element 33 of the liquid level detection component 30 extends into the liquid storage container 20 to detect the liquid level therein.

[0088] Application Example 7

[0089] In application example seven, a cleaning device is provided, which is a floor scrubber. The floor scrubber has two liquid storage containers 20, one of which is a clean water tank and the other is a wastewater tank. Each liquid storage container 20 is provided with a liquid level detection component 30 provided in any of application examples one to four. The liquid level detection component 30 at the clean water tank is used to detect the liquid level in the clean water tank, and the liquid level detection component 30 at the wastewater tank is used to detect the liquid level in the wastewater tank.
