Description

[0001] This application is a divisional of the Chinese patent application entitled “Cleaning Equipment and Liquid Level Detection Components” filed on March 1, 2023 and application number “202320358290.1”. Technical Field

[0002] The present application relates to the technical field of cleaning equipment, and in particular to a cleaning equipment and a liquid level detection component. Background Art

[0003] For cleaning equipment such as floor scrubbers, a liquid storage container for storing liquid is usually provided. For example, after the floor scrubber is used, sewage will be generated, so a sewage tank (also called a recycling tank) is provided in the floor scrubber to store the sewage generated after cleaning. When the liquid level in the sewage tank reaches a certain height, the sewage tank needs to be cleaned.

[0004] Generally, the existing technology uses a liquid level detection probe to detect the liquid level in the sewage tank. However, the shape, size and other parameters of the liquid level conductive probe are fixed, and its applicability is poor. If the structure of the floor scrubber or other cleaning equipment changes, the shape and size of the liquid level detection probe also need to be changed accordingly, and then it is necessary to prepare a new production mold for the liquid level detection probe, which is costly.

[0046] The present application provides a cleaning device and a liquid level detection component, which are described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of the present application. In the following embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments. In the case that the present application does not clearly state or there are no obstacles to combination, the parts described in each embodiment can be combined with each other, and the examples in this embodiment do not constitute an improper limitation on such combination.

[0047] An embodiment of the present application provides a cleaning device, which may be a handheld vacuum cleaner, a floor scrubber, a carpet cleaner, a desktop cleaner, a cleaning robot, or other devices used for cleaning, etc., but this embodiment does not limit them.

[0048] Here, see Figure 1 The cleaning device mainly includes a body 10, a liquid storage container 20 and a liquid level detection component 30 (see Figure 5 ).

[0049] Please continue to read Figure 1 , the body 10 roughly forms the main structural outline of the cleaning device, and can be used to install, carry, and connect other components. Exemplarily, the body 10 includes a main body 11, and a hand-held rod 12, a suction source, a power supply assembly, a cleaning head 13, a controller, etc. arranged on the main body 11, and the hand-held rod 12 is used for the user to hold and operate the cleaning device. The suction source, the power supply assembly, the cleaning head 13, the controller or other components in addition can be installed on the hand-held rod 12. Here, the cleaning head 13 is arranged at the bottom of the hand-held rod, and the power supply assembly can be arranged at a position slightly lower than the hand-held rod to lower the center of gravity of the overall device. Of course, this embodiment does not limit it. Here, the controller includes structures such as chips and circuits, which can be connected to other components to control other components, and the power supply assembly is used to connect to components that need power supply and supply power to these components. For example, the power supply assembly, the controller, the cleaning head 13 and the suction source are connected, the cleaning head 13 has a cleaning cavity and is equipped with a rotating body such as a roller brush, and the controller can control the rotation of the rotating body of the cleaning head 13, and control the suction source to work to form a suction airflow, thereby cleaning the surface to be cleaned. Of course, it can be 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 the corresponding components on the shell structure. Of course, the above example of this embodiment does not constitute an undue limitation to the present application.

[0050] The liquid storage container 20 is arranged on the body 10, and it has a containing space for storing liquid used for cleaning equipment or liquid generated or absorbed by the cleaning equipment. Usually, the liquid storage container 20 is installed on the body 10 in a detachable manner (such as a snap connection, etc.) so that it can be disassembled and cleaned and / or replenished with liquid, etc. Of course, this embodiment does not limit it. Exemplarily, in one example, the liquid storage container 20 is used to store clean water or cleaning liquid, etc., and the clean water or cleaning liquid is used to supply to the cleaning cavity of the cleaning equipment or to the surface to be cleaned, so as to better achieve the cleaning of the surface to be cleaned. Exemplarily, in another example, the liquid storage container 20 is used to store sewage generated after the cleaning equipment is working, and the sewage on the surface to be cleaned and / or the cleaning cavity will be sucked into the liquid storage container 20. Among them, the liquid storage container 20 supplies the liquid therein to a designated position through a pipeline and a suction device such as a motor arranged in the pipeline, and the suction device such as the motor here and the suction source for forming the suction airflow mentioned above can be the same component. Of course, in some embodiments, the suction device such as the motor here and the suction source for forming the suction airflow mentioned above can also be different components, and the example in this embodiment does not constitute an undue limitation thereto.

[0051] In some embodiments, see Figure 2 The liquid storage container 20 includes a container body 21 and a cover 22. The container body 21 has the accommodation space. Usually, an opening is provided on one side of the accommodation space in the vertical direction. The cover 22 can be openably fitted on the container body 21 to close or open the opening. Exemplarily, the cover 22 can be snapped on the opening. Figure 3 and Figure 4 , which shows a schematic diagram of the cover 22 after being removed from the container body 21. In other embodiments, the cover 22 may also be pivotally connected to one side of the opening, magnetically engaged at the opening, or openably engaged at the opening in other ways, and the examples in this embodiment do not constitute an undue limitation thereto.

[0052] In further embodiments, see Figure 2 The cover body 22 is provided with a containing shell 221 extending in a direction close to the container body 21, and the inner cavity of the containing shell 221 is used to contain at least a part of the liquid level detection assembly. Exemplarily, when two liquid level detection assemblies are provided, the cover body 22 may be provided with two mutually spaced containing shells 221 to respectively contain at least a part of the two liquid level detection assemblies. Here, the containing shell 221 and the cover body 22 may be integrally formed, or the containing shell 221 may be additionally connected to the cover body 22, and this embodiment does not limit this.

[0053] Furthermore, it is understandable that Figure 2 In order to show the structure inside the container body 21, part of the outer wall of the container body 21 is removed so as to show the containing space and the containing shell 221 therein, but in actual products, the container body 21 usually has a complete outer wall to form the containing space.

[0054] Furthermore, here, this embodiment only exemplifies the structure of the liquid storage container 20. In other embodiments, the structure of the liquid storage container 20 may be different. For example, the cover 22 may be arranged on the side or other position of the container body 21. Alternatively, the liquid storage container 20 may not have the cover 22, but may be an integrated, generally closed structure with a channel for water in and out, etc. The examples in this embodiment do not constitute undue restrictions on the structure and shape of the liquid storage container 20.

[0055] The liquid level detection component 30 is used to detect the liquid level in the liquid storage container 20 so as to realize related functions. The related functions may be providing related prompts to the user, performing related operations or other functions, which are not limited in this embodiment.

[0056] Here, see Figure 5 The liquid level detection component 30 includes a conductive connecting member 31, a flexible conductive member 32 and a conductive detection member 33.

[0057] Among them, see Figure 3 and Figure 4 The conductive connecting member 31 is disposed on the liquid storage container 20 to connect with the body 10 (see Figure 1 ) are coupled and realize the transmission of electrical signals. Exemplarily, the conductive connector 31 is arranged on the cover 22 of the liquid storage container 20, and is located on the side of the cover 22 away from the container body 21, so that when the liquid storage container 20 is assembled on the body 10, the conductive connector 31 can be coupled with the corresponding part on the body 10. Specifically, the conductive connector 31 can be coupled to the controller of the body 10, for example, coupled to the detection circuit of the controller. In a further example, a contact is arranged on the body 10 at a position corresponding to the conductive connector 31, and when the liquid storage container 20 is assembled on the body 10, the conductive connector 31 is connected to the contact and forms an electrical connection. The contact is arranged in the detection circuit of the controller, and then the conductive connector 31 forms a coupling with the controller. Of course, in other embodiments, the arrangement position of the conductive connector 31 may be different, and the coupling method of the conductive connector 31 with the body 10 may also be different, and the example of this embodiment does not constitute an improper limitation thereto.

[0058] Please refer to Figure 5 , the flexible conductive member 32 is connected to the conductive connecting member 31 and the conductive detecting member 33, and is used to realize the electrical connection between the conductive connecting member 31 and the conductive detecting member 33. Here, the flexible conductive member 32 can be a wire or a flexible printed circuit (FPC) or other flexible conductive components, etc. The flexible conductive member 32 can be bent or folded or wound, etc., so as to adapt to the requirements of different sizes and application spaces, and the flexible conductive member 32 can be conveniently electrically connected with the conductive connecting member 31 and the conductive detecting member 33 by welding or other methods, so that the conductive connecting member 31 of a suitable size can also be selected according to actual needs.

[0059] The conductive detection member 33 is at least partially located in the accommodation space to detect the liquid level in the accommodation space. Here, the conductive detection member 33 is coupled to the controller through the flexible conductive member 32 and the conductive connection member 31, so that the detection signal can be transmitted to the controller of the body 10.

[0060] Here, in some embodiments, the conductive detection member 33 can be made of non-metallic conductive material. This is because the conductive detection member 33 needs to be in contact with the liquid in the liquid storage container 20 in order to detect the liquid level, and when the conductive detection member 33 is in contact with the liquid for a long time, it is prone to oxidation, rust and other problems. In the embodiment of the present application, the conductive detection member 33 is made of non-metallic conductive material, thereby reducing the risk of rust on the conductive detection member 33. Exemplarily, the non-metallic conductive material is graphite, selenium or silicon. Of course, it can be understood that in other embodiments, the non-metallic conductive material is not limited to the above, or the conductive detection member 33 can also be made of metal material, which can also achieve the technical effect of liquid level detection, and the example of this embodiment does not constitute an improper limitation thereto.

[0061] Here, the resistance of the conductive connector 31, the flexible conductive member 32 and the conductive detection member 33 connected in sequence is relatively small. For example, in one example, when the conductive detection member 33 is made of graphite, the overall resistance of the conductive connector 31, the flexible conductive member 32 and the conductive detection member 33 connected in sequence is 2-6 ohms. The inventor of the present application is aware of a liquid level detection component, which forms a hard conductive structure by an injection molded part doped with carbon fiber, and a metal sheet is arranged on the injection molded part as a detection component, and the injection molded part has an approximate resistance of 30-40 ohms when electrical conduction is formed between the metal sheet and the controller. It can be seen that the use of the liquid level detection component provided in the embodiment of the present application helps to reduce the conduction resistance of the liquid level detection component, thereby making the liquid level detection more sensitive and effective.

[0062] Here, in some embodiments, please continue to refer to Figure 5 , the liquid level detection component 30 also includes a shell 34, the conductive detection member 33 is fixed in the shell 34, and the shell 34 is provided with an exposure port 341 to expose at least a part of the conductive detection member 33, so that the conductive detection member 33 is in contact with the liquid outside and realizes the detection function. Exemplarily, the conductive detection member 33 is fixed in the shell 34 by glue filling, that is, the conductive detection member 33 is glued in the shell 34, and an adhesive layer is formed between the conductive detection member 33 and the shell 34. This fixing method is simple to operate, easy to implement, and has low cost. It does not require a complex connection structure, and can also play an insulating, sealing, and moisture-proof effect. It is particularly suitable for a conductive detection member 33 made of non-metallic conductive materials. Exemplarily, the liquid level detection component 30 also includes a first sealing member, which is interference-fitted between the shell 34 and the conductive detection member 33 to fix the conductive detection member 33. The first sealing member can be a sealing ring, etc. In other embodiments, the conductive detection member 33 and the housing 34 may be fixedly connected by snap-fitting, Velcro fitting or other methods different from the above, and the example of this embodiment does not constitute an undue limitation thereto.

[0063] The housing 34 may be used to protect the conductive detection member 33, and / or the housing 34 may be provided with an assembly structure so as to assemble the housing 34 and the conductive detection member 33 into the liquid storage container 20. Figure 6 and Figure 7 , the housing 34 is provided with a snap-fitting groove 342, here, the housing 34 is provided with a flange 343 protruding outwardly in the circumferential direction, and a plurality of snap-fitting portions 344 protruding outwardly in the circumferential direction, the flange 343 and the snap-fitting portions 344 are arranged at intervals in the length direction of the housing 34 to form the snap-fitting groove 342. Here, the number of the snap-fitting portions 344 is 2, and in other embodiments, the number of the snap-fitting portions 344 may also be different, and this implementation does not limit it.

[0064] See also Figure 5 Here, in some embodiments, the liquid storage container 20 includes a cover body 22, and a accommodating shell 221 is provided on the cover body 22. The shell 34 and at least part of the flexible conductive member 32 are accommodated in the accommodating shell 221. The accommodating shell 221 is provided with a protruding snap-fitting protrusion 222 on the inner side, and the snap-fitting protrusion 222 is arranged corresponding to the snap-fitting groove 342. The two can cooperate with each other to fix the shell 34 and the conductive detecting member 33 to the accommodating shell 221, that is, to the liquid storage container 20.

[0065] It is understandable that in other embodiments, a snap-in groove 342 may be provided on the containing shell 221, and a snap-in protrusion 222 may be provided on the shell 34 correspondingly; in addition, the snap-in groove 342 or the snap-in protrusion 222 may not be provided on the containing shell 221, but may be provided on other components of the liquid storage container 20, and it is only necessary to fix the shell 34 to the liquid storage container 20; further, the matching connection method between the shell 34 and the containing shell 221 may not be limited to the above, for example, the two may be bonded, welded, etc., and the example of this embodiment does not constitute an undue limitation.

[0066] In a further embodiment, on the basis of fixing the housing 34 to the accommodating shell 221, a matching groove is further provided on the housing 34, and the matching groove is used to embed a second sealing ring, and the second sealing ring can improve the sealing between the accommodating shell 221 and the housing 34. It can be understood that in other embodiments, the matching groove can also be provided on the inner side of the accommodating shell 221, and this embodiment does not limit it.

[0067] In addition, in some embodiments, please continue to refer to Figure 5 The end of the shell 34 away from the conductive connector 31 is provided with a rubber coating 345, and the rubber coating helps to achieve the insulation, moisture-proof and other effects.

[0068] It can be seen that in the embodiment provided in the present application, the conductive detection member 33 is connected to the conductive connection member 31 through the flexible conductive member 32, and then coupled to the body 10 through the conductive connection member 31. The flexible conductive member 32 is between the conductive detection member 33 and the conductive connection member 31. The flexible conductive member 32 can be bent, wound, etc. according to actual needs to change the length of the flexible conductive member 32, and then the liquid level detection assembly 30 can be applied to liquid storage containers 20 of different sizes. Therefore, it is not necessary to set liquid level detection assemblies 30 of different sizes for liquid storage containers 20 of different shapes and sizes, which reduces the cost of production and use.

[0069] Moreover, in the embodiments of the present application, a modular design of each component is achieved through this arrangement. The conductive connecting member 31, the flexible conductive member 32 and the conductive detecting member 33 are no longer a rigid structure connected as one. Each component can be prepared separately, and a flexible conductive member 32 of appropriate length and size can be selected according to actual needs, so as to better meet the needs of actual space layout.

[0070] Here, in some embodiments, see Figure 5The liquid level detection component 30 also includes a conductive elastic member 35. When the conductive connecting member 31 is connected to the liquid storage container 20 (for example, the cover 22 of the liquid storage container 20), the conductive elastic member 35 is arranged between the flexible conductive member 32 and the conductive connecting member 31 and is in a compressed state to form an electrical connection between the flexible conductive member 32 and the conductive connecting member 31.

[0071] Exemplarily, the conductive elastic member 35 is a spring. Of course, in other embodiments, the conductive elastic member 35 may also be other elastic bodies such as shrapnel. Usually, the conductive elastic member is made of metal material to achieve the function of conductivity, and of course, 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 a groove, etc. The edge of the sheet-like metal component is bent and embedded in the opening or the groove to achieve 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.

[0072] Here, the conductive elastic member 35 includes a fixed end and a free end. The fixed end is arranged on the liquid storage container 20. For example, a connecting column is arranged on the cover body 22 of the liquid storage container 20. The connecting column is provided with a protrusion protruding in the circumferential direction at one end away from the conductive connector 31. The conductive elastic member 35 can be sleeved on the connecting column, and the fixed end can be abutted and / or connected to the protrusion. The free end corresponds to the position of the connecting part. When the conductive connector 31 is installed at the position of the connecting part, the conductive connector 31 presses against the free end to make the conductive elastic member 35 in a compressed state. When the conductive connector 31 is not installed, the conductive elastic member 35 is in an uncompressed state, and it will extend toward the connecting part compared to the compressed state.

[0073] Thus, when the conductive connector 31 is installed in place, the conductive elastic member 35 is in a state of being compressed by the conductive connector 31, thereby ensuring contact between the conductive connector 31 and the conductive elastic member 35, thereby achieving electrical conduction between the two. At the same time, the conductive elastic member 35 is connected to the flexible conductive member 32, thereby achieving electrical conduction between the conductive detection member 33, the flexible conductive member 32 and the conductive connector 31. That is, through this arrangement, the connection failure between the conductive connector 31 and the flexible conductive member 32 can be reduced, thereby improving the effectiveness of the liquid level detection assembly 30.

[0074] In some embodiments, two groups of the liquid level detection components 30 are provided on the cleaning device. When the liquid level in the liquid storage container 20 reaches a preset liquid level height, the conductive detection components 33 of the two groups of liquid level detection components 30 are in contact with the liquid and the circuit is turned on by the liquid. That is, after the electrical signal is sent by the controller, it passes through the conductive connector 31, the flexible conductive component 32 and the conductive detection component 33 of the first group of liquid level detection components 30 in sequence, and is transmitted to the conductive detection component 33 of the second group of liquid level detection components 30 via the liquid. Then, the electrical signal passes through the flexible conductive component 32 and the conductive connector 31 of the second group of liquid level detection components 30 in sequence and is transmitted to the controller, thereby forming a circuit conduction. As a result, the controller recognizes that the liquid level in the liquid storage container 20 has reached a preset liquid level height, thereby controlling the cleaning device to shut down and / or sending a prompt signal to the user.

[0075] It is understandable that in other embodiments, the potential difference between the conductive connectors 31 of the two groups of liquid level detection components 30 can also be used to determine whether the liquid has reached a preset liquid level. For example, one conductive connector 31 is grounded, and the controller detects that the voltage of the conductive connector 31 is zero voltage. At this time, the other conductive connector 31 is not grounded, and the controller detects that the voltage of the other conductive connector 31 is greater than zero, so that a voltage difference is formed between the two conductive connectors 31. After the conductive detection member 33 contacts the liquid, the voltage difference will change, and the controller compares the voltage difference with the preset standard value to determine whether the liquid has reached the preset liquid level.

[0076] Accordingly, in order to better achieve the technical effect of the embodiments of the present application, the embodiments of the present 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.

[0077] Here, the liquid level detection assembly 30 includes a conductive connection member 31, a flexible conductive member 32, and a conductive detection member 33. The conductive connection member 31 is disposed on the liquid storage container 20 and is used to couple to an external circuit; the flexible conductive member 32 is connected to the conductive connection member 31; and the conductive detection member 33 is connected to the flexible conductive member 32.

[0078] In some embodiments, the conductive detection member 33 is made of non-metallic conductive material.
