Technical Field

[0001] This application relates to the technical field of vacuum cleaners, and particularly to a cleaning head. Background Art

[0002] A vacuum cleaner uses a vacuum motor to drive the blades to rotate at high speed, generating a negative air pressure inside the sealed housing, thereby generating an air flow and sucking up dust debris to achieve the cleaning purpose. In traditional technologies, the cleaning head of a vacuum cleaner is often equipped with a roller brush to improve the cleaning ability. The roller brush works in cooperation with the main body of the vacuum cleaner (equipped with a vacuum motor, etc.) so that dust and other substances in the target area can be quickly picked up.

At the same time, the term "and / or" used in this specification includes any and all combinations of the related listed items.

[0047] As described in the background art, the cleaner heads on the market are not compatible with the main bodies of vacuum cleaners of different brands, which results in poor cleaning performance of the vacuum cleaners. As an example, existing AC-powered vacuum cleaners either do not have an electric roller brush or are equipped with a pneumatic roller brush for AC-powered vacuum cleaners. This is because the air flow generator of the AC-powered vacuum cleaner is connected to an alternating current (e.g., mains power), while common electric roller brushes are mostly powered by direct current, which causes the existing AC-powered vacuum cleaners and electric roller brushes to not be directly compatible for use.

[0048] If an AC-powered vacuum cleaner is to be used in conjunction with an electric roller brush, an AC-DC converter needs to be provided between the two to convert part of the alternating current into direct current, which in turn increases the cost of the vacuum cleaner. In addition, the electric roller brush needs to be provided on the cleaner head, and the cleaner head usually needs to clean a variety of target areas, including but not limited to sofas, bed surfaces, cabinet tops, or narrow corners, and is far from the air flow generator and the power source. Therefore, additional wires are also needed to electrically connect the power source and the electric roller brush, which further increases the cost of the vacuum cleaner.

[0049] Based on this, as Figures 1 to 4 shown, the present disclosure provides a cleaning device (e.g., a vacuum cleaner). The cleaning device includes a fluid passage 100, an air flow generator 110, and a cleaner head 130 in one or more of the following embodiments.

[0050] In one embodiment, a cleaner head 130 is provided. Referring to Figures 5 to 11 , the cleaner head 130 includes a roller brush motor 131, a roller brush 132, a control module 133, a DC power supply module 134, and a connector 1312.

[0051] The roller brush motor 131 is used to drive the roller brush 132. The roller brush 132 is used to clean the target area. The roller brush 132 can be provided on the side of the cleaner head 130 facing the target area. Driven by the roller brush motor 131, the roller brush 132 rotates around the axis of rotation.

[0052] The DC power supply module 134 is used to supply power to the roller brush motor 131. As an example, the DC power supply module 134 can include a plurality of battery packs 1341, and each battery pack 1341 can include a plurality of battery cells.

[0053] The battery pack 1341 can be detachably provided on the cleaner head 130 for easy charging. Of course, the battery pack 1341 can also be fixedly provided on the cleaner head 130 and is equipped with a charging socket.

[0054] The control module 133 is connected to the DC power supply module 134. The control module 133 is used to control the DC power supply module 134 to supply power to the roller brush motor 131. As an example, the control module 133 may include multiple control chips and control circuits. The control module 133 can start the DC power supply module 134 to enable the battery pack 1341 to supply power to the roller brush motor 131, or the control module 133 can also conduct the loop between the battery pack 1341 and the roller brush motor 131 to enable the battery pack to supply power to the roller brush motor 131. The specific form of the control module 133 is not limited in this embodiment.

[0055] The connecting member 1312 is disposed on the housing of the cleaner head 130. The connecting member 1312 is used to connect the fluid passage 100. The other end of the fluid passage 100 is connected to the air flow generator 110 (for example, the vacuum motor 111). As an example, alternating current is connected to the vacuum motor 111 to generate an air flow, and the roller brush 132 and the air flow together make it easier to pick up substances such as dust. The material of the connecting member 1312 can be elastic. The elastic material enables the cleaner head 130 to be adapted to fluid passages 100 of various sizes.

[0056] In this embodiment, by arranging the roller brush motor 131, the roller brush 132, the DC power supply module 134, and the control module 133 on the cleaner head 130, and the control module 133 controls the DC power supply module 134 to supply power to the roller brush motor 131, the vacuum cleaner can use the roller brush 132 to clean the target area while various air flow generators 110 are started. Moreover, when the air flow generator 110 generates a strong air flow, the roller brush 132 can roll up substances such as dust, enhancing the cleaning ability of the vacuum cleaner. In addition, the roller brush motor 131 in this embodiment is powered by the DC power supply module 134 instead of alternating current, so that the vacuum cleaner does not need to be provided with an AC-DC converter, and also does not need to set up an additional circuit to connect the roller brush motor 131 to the mains, reducing the manufacturing cost of the vacuum cleaner.

[0057] In the related art, a vacuum cleaner either does not have a cleaner head or is equipped with an original cleaner head 10 (including a conventional floor brush and a suction port structure, etc.). For example, Figure 1 A conventional floor brush is provided at the bottom of the shown upright vacuum cleaner. The conventional floor brush is used to support the vacuum cleaner main body and is not detachably connected to the vacuum cleaner main body. Obviously, this kind of conventional floor brush cannot be used to clean local positions such as sofas. For another example, as shown in 2, the original cleaner head 10 provided at one end of the fluid passage 100 of the horizontal vacuum cleaner is a suction port structure, and the suction port structure does not have an electric roller brush, making it almost have no carpet cleaning ability.

[0058] The cleaner head 130 provided in this embodiment can be used as an accessory for an existing vacuum cleaner. It can be connected to an upright vacuum cleaner through the fluid passage 100 and used in place of the conventional floor brush (asFigure 1 ) and can also be used interchangeably with the suction nozzle structure (such as Figure 2 ). When the cleaner head 130 provided in this embodiment is used interchangeably with the original cleaner head 10, one end of the fluid channel 100 docking the cleaner head 130 can be sealed. During the replacement process, the vacuum degree of the fluid channel 100 only changes locally, so as to ensure the vacuum degree of the cleaner head during operation.

[0059] Furthermore, at least part of the fluid channel 100 can be of a corrugated structure, so that the structure of the fluid channel 100 has flexibility, and further enables the fluid channel 100 to adapt to different working environments (such as the surface of a sofa, etc.). As an example, the material of the fluid channel 100 can be plastic or metal, etc. The two ends of the fluid channel 100 are respectively connected to the air flow generator 110 and the cleaner head 130. Please refer to Figure 3 and Figure 4 , the air flow generator 110 includes a vacuum motor 111. The vacuum motor 111 is connected to an AC power plug 120 to access alternating current (such as mains power). The air flow generator 110 can also include a collection device 112 for collecting dust and other substances. When the vacuum motor 111 operates, an air flow is generated in the fluid channel 100, and dust and other substances flow into the fluid channel 100 from the cleaner head 130 along with the gas and are collected into the collection device 112.

[0060] In addition, the cleaner head 130 can also include structures such as a handle 1311. The handle 1311 facilitates the user to disassemble or operate the cleaner head 130 and the fluid channel 100. The handle 1311 can be arranged on the outer shell of the cleaner head 130, and the handle 1311 can be arranged opposite to the position of the chamber opening of the roller brush 132, so as to facilitate the user to operate the cleaner head 130. Specifically, the handle 1311 can be arranged at the middle position of the outer shell of the cleaner head 130. When the user applies force to the cleaner head 130, the chamber opening of the roller brush 132 can be kept in contact with the surface of the target area, so as to maintain the vacuum degree of the cleaner head 130. In addition, the handle 1311 can extend upward from the outer shell of the cleaner head 130, or the handle 1311 can extend from the outer shell of the cleaner head 130 to the connecting piece 1312, or the handle 1311 can be arranged in an inverted U shape on the surface of the outer shell of the cleaner head 130. When the user uses the cleaner head 130, the cleaning position of the cleaner head 130 can be easily controlled by grasping the handle 1311. For example, the main body of an AC vacuum cleaner is usually bulky, and because it is connected to AC power, the AC vacuum cleaner cannot be too far away from the plug, so the main body of the AC vacuum cleaner is not convenient to move. When cleaning different areas, the user can grasp the handle 1311 and cooperate with the long and flexible fluid channel 100 to use the cleaner head 130 to clean a large range of surfaces.

[0061] In one embodiment, the cleaner head 130 further includes a drive circuit 135.

[0062] Please refer to Figure 7 , the drive circuit 135 is connected between the control module 133 and the roller brush motor 131. The drive circuit 135 is configured to drive the roller brush motor 131 under the control of the control module 133. As an example, the drive circuit 135 may include an amplifier to amplify the electrical signal sent by the control module 133. Alternatively, the drive circuit 135 may include semiconductor devices such as triodes to control the current value in the drive circuit 135, and thus control the rotation speed, torque or steering of the roller brush motor 131.

[0063] In this embodiment, the drive circuit 135 is provided between the control module 133 and the roller brush motor 131, so as to control the parameters of the roller brush motor 131 by controlling the drive circuit 135, and increase the usage modes of the roller brush assembly.

[0064] In one embodiment, the DC power supply module 134 includes a battery pack 1341, and the cleaner head 130 includes a power indication module 136.

[0065] The power indication module 136 is connected to the control module 133. The power indication module 136 is configured to display the current power of the battery pack 1341 under the control of the control module 133. For example, the control module 133 may obtain the current power of the battery pack 1341 and send the current power of the battery pack 1341 to the power indication module 136. The power indication module 136 may include a display screen to display the numerical value or image of the current power of the battery pack 1341 through the display screen.

[0066] Further, please refer to Figure 12 and Figure 14 , the power indication module 136 is further configured to send out a power warning signal when the current power of the battery pack 1341 is less than a preset power C. Exemplarily, the preset power C may be 10% of the total power of the battery pack 1341.

[0067] In one example, a comparator may be provided in the power indication module 136. One input terminal of the comparator is connected to a reference voltage corresponding to the preset power, and the other input terminal of the comparator is connected to the control module 133 and obtains a power voltage corresponding to the current power of the battery pack 1341. After comparing the reference voltage with the power voltage by the comparator, the output terminal of the comparator may output a corresponding electrical signal.

[0068] In another example, the power indication module 136 may be provided with a chip, and the calculator provided in the chip compares the current power with the preset power and outputs a comparison result.

[0069] When the current power of the battery pack 1341 is less than the preset power, the power indicator module 136 may send out a power warning signal by flashing, vibrating or roaring, or by one or more of the above.

[0070] In this embodiment, the current power of the battery pack 1341 is displayed by setting the power indicator module 136, so as to quickly obtain the current power of the battery pack 1341, which is convenient for the use of the vacuum cleaner. In addition, the user can use the vacuum cleaner or charge the battery pack 1341 according to the result displayed by the power indicator module 136.

[0071] In one embodiment, the cleaner head 130 includes a vacuum level monitoring module 137 .

[0072] The vacuum monitoring module 137 is disposed on a side of the cleaner head 130 close to the fluid channel 100. The vacuum monitoring module 137 is used to monitor the vacuum of the cleaner head 130 and send the monitored vacuum value to the control module 133. As an example, the vacuum monitoring module 137 may include a vacuum sensor 1371.

[0073] Furthermore, the connector 1312 in the cleaner head 130 may be provided with an airflow channel. The airflow channel is fluidically connected to the fluid channel 100, the roller brush 132 may be provided at the end of the airflow channel, and the vacuum monitoring module 137 may more accurately monitor the vacuum in the airflow channel, thereby controlling the roller brush 132 more quickly.

[0074] After the vacuum monitoring module 137 sends the monitored vacuum value to the control module 133, if the vacuum value reaches a preset value within a preset time, the control module 133 controls the DC power supply module 134 to supply power to the roller brush motor 131 to save power. In one example, if the vacuum cleaner is not turned on, there is no need to control the DC power supply module 134 to supply power to the roller brush motor 131. In another example, if the bottom surface of the cleaner head 130 leaves the target area (for example, the cleaner head 130 is lifted), then the target area does not need to be cleaned at this time, and the roller brush motor 131 does not need to be started.

[0075] See also Figure 12 and Figure 14 For example, when the vacuum degree of the cleaner head 130 lasts for a period of T and the vacuum degree is greater than A, it means that the vacuum motor 111 of the vacuum cleaner attached with the cleaner head 130 is started normally, and the bottom surface of the cleaner head 130 is in contact with the target area. At this time, the roller brush motor 131 can be driven to clean. T can be 1s-5s. For example, T (i.e., the preset duration) can be 2s. A (i.e., the preset value) can be 8kPa-12kPa. For example, A can be 10kPa.

[0076] It can be understood that when the cleaner head 130 is removed from the vacuum cleaner or the vacuum cleaner is powered off, the monitoring result of the vacuum degree monitoring module 137 will change. At this time, for example, when the vacuum degree monitoring module 137 monitors that the vacuum degree is less than or equal to A and the duration is greater than or equal to B, it indicates that the vacuum cleaner has stopped cleaning work. The control module 133 can control the vacuum degree monitoring module 13, the drive circuit 135, the roller brush motor 131, etc. to stop working to save power. When the vacuum degree monitoring module 13 monitors that the vacuum degree is less than or equal to A and the duration is less than B, it indicates that the cleaner head 130 of the vacuum cleaner is briefly lifted from the target area. At this time, the control module 133 can control the roller brush motor 131, etc. to stop working to reduce the noise and power loss caused by the rotation of the roller brush. For example, A can be 8 kPa - 12 kPa. For example, A can be 10 kPa. B can be 50 s - 70 s. For example, T can be 60 s.

[0077] In this embodiment, by setting the vacuum degree monitoring module 137 to monitor the vacuum degree of the cleaner head 130 in real time, the working state of the vacuum cleaner can be quickly obtained. Moreover, this embodiment can also control the start or stop of the roller brush motor 131 according to the monitoring result of the vacuum degree monitoring module 137 to increase the flexibility of use of the vacuum cleaner and save power.

[0078] In one example, the vacuum cleaner is provided with a switch control member 1381. The switch control member 1381 is used to control the DC power supply module 134 to supply power to the roller brush motor 131.

[0079] The switch control member 1381 can be disposed on the surface of the cleaner head 130. As an example, the switch control member 1381 can include structures such as a button or a touch screen. The switch control member 1381 can also be disposed at the end of the cleaner head 130 close to the fluid passage 100. At this time, when the end of the fluid passage 100 contacts the fluid passage 100 with the vacuum motor 111, the fluid passage 100 triggers the switch control member 1381 by means of pressing or the like.

[0080] The cleaner head 130 includes a switch detection module 138. Please refer to Figure 13 and Figure 14 , the switch detection module 138 is connected to the switch control member 1381 and the control module 133, and is used to send the status information of the switch control member 1381 to the control module 133.

[0081] Exemplarily, the switch control member 1381 includes a push-button switch or a slide switch. It can be understood that when the switch control member 1381 is a push-button switch, the user triggers the operation by pressing up and down. When the switch control member 1381 is a slide switch, the user triggers the operation by sliding forward and backward or left and right. Further, the push-button switch may include a self-locking switch and a momentary switch. In one example, after the user presses the self-locking switch, the elastic piece of the self-locking switch locks, keeping the switch detection module 138 in a conducting state. When the user presses the self-locking switch again, the elastic piece unlocks, and the circuit of the switch detection module 138 is disconnected. In another example, in order to reduce user operation, a momentary switch can be selected. At this time, after the user presses the momentary switch and then releases it, the circuit of the switch detection module 138 is briefly triggered, and the control circuit of the control module 133 obtains a signal to start the roller brush motor 131. When the user touches the momentary switch again, the control circuit of the control module 133 obtains a signal to stop the roller brush motor 131. Of course, when the push-button switch is a switch other than the momentary switch (for example, the push-button switch is a self-locking switch), after these switches are closed by pressing or other means, circuits such as the DC power supply module 134 are disconnected and cannot be connected again.

[0082] Specifically, when the switch control member 1381 includes a push-button switch, when the switch control member 1381 is pressed down, it indicates that the switch is turned on. The switch detection module 138 sends the information that the switch is turned on to the control module 133. The control module 133 controls the power indication module 136 to display the current power of the battery pack 1341. At the same time, the control module 133 can also control the vacuum degree monitoring module 137 to monitor the vacuum degree. When the switch control member 1381 rebounds, it indicates that the switch is turned off. The switch detection module 138 sends the information that the switch is turned off to the control module 133. The control module 133 controls the DC power supply module 134 to stop supplying power to the roller brush motor 131, and at the same time controls the vacuum degree monitoring module 137, the power indication module 136, and the lighting module 1310 to stop working.

[0083] In this embodiment, by setting the switch control member 1381 and the switch detection module 138, the start and stop of the roller brush motor 131 can be flexibly controlled, saving power.

[0084] In one example, please refer to Figure 13 , the cleaner head 130 includes a storage module 139.

[0085] The storage module 139 is connected to the control module 133. The storage module 139 is used to store the operation information of the cleaner head 130. As an example, the storage module 139 can store information such as the operation duration of the cleaner head 130 or the previous operation record of the cleaner head 130.

[0086] The storage module 139 can also be used to store the state of the switch control 1381. In one example, when the switch control 1381 is turned on but the battery pack 1341 has insufficient power, the cleaner head 130 cannot start properly. After replacing the battery pack 1341 with a new one or charging the battery pack 1341, the control module 133 reads the information in the storage module 139 and learns that the switch control 1381 is in the on state. At this time, the control module 133 controls the DC power supply module 134 to supply power to the roller brush motor 131. In another example, when the switch control 1381 is turned off, after replacing the battery pack 1341 with a new one or charging the battery pack 1341, the control module 133 reads the information in the storage module 139 and learns that the switch control 1381 is in the off state. Then the control module 133 does not control the DC power supply module 134 to supply power to the roller brush motor 131.

[0087] In this embodiment, by setting the storage module 139 to store the operation information of the cleaner head 130, it provides help for the next use in case of sudden power failure of the battery pack 1341 or the like.

[0088] In one embodiment, the cleaner head 130 includes a lighting module 1310.

[0089] The lighting module 1310 is connected to the control module 133. The lighting module 1310 is used to illuminate the target area when the roller brush motor 131 is driven. As an example, the lighting module 1310 can include a plurality of lighting lamps 13101, and the lighting lamps 13101 can be arranged on the surface of the cleaner head 130. While the DC power supply module 134 supplies power to the roller brush motor 131, the DC power supply module 134 can also supply power to the lighting lamps 13101.

[0090] Please refer to Figure 12 and Figure 14 In one example, after the vacuum degree monitoring module 137 sends the monitored vacuum degree value to the control module 133, when the vacuum degree value reaches the preset value within the preset time period, the control module 133 can control the DC power supply module 134 to supply power to the roller brush motor 131. At the same time, the control module 133 controls the lighting module 1310 to illuminate the target area to save electricity.

[0091] In this embodiment, by setting the lighting module 1310, it illuminates the target area, facilitating the user to view the dirt condition of the target area, thereby improving the cleaning effect.

[0092] It can be understood that the above modules of the vacuum cleaner can also adopt other forms, not limited to the forms mentioned in the above embodiments, as long as they can achieve the functions of the respective modules.

[0093] Based on this, please refer to Figure 12 andFigure 14 , the figure shows a flowchart of a vacuum cleaner control method, which is applied to the vacuum cleaner in the foregoing embodiment. When the vacuum cleaner is not provided with the switch detection module 138, reference can be made to Figure 12 the flowchart of the vacuum cleaner control method shown. When the vacuum cleaner is provided with the switch detection module 138, reference can be made to Figure 14 the flowchart of the vacuum cleaner control method shown.

[0094] In one embodiment, please refer to Figure 12 , the vacuum sensor 1371 in the vacuum degree monitoring module 137 monitors the vacuum degree. When the vacuum degree value monitored by the vacuum sensor 1371 is greater than A, timing is started. When the vacuum degree value is greater than A and lasts for more than T time, it indicates that the vacuum motor 111 of the vacuum cleaner starts normally, and the bottom surface of the cleaner head 130 contacts the target area. At this time, the roller brush motor 131 starts and the lighting module 1310 lights up to perform the cleaning work. When the vacuum degree value is greater than A but does not last for more than T time, the vacuum sensor 1371 is controlled to continue monitoring the vacuum degree. When the vacuum degree value is less than or equal to A and lasts for more than B time, it indicates that the vacuum motor 111 of the vacuum cleaner is abnormal, or the bottom surface of the cleaner head 130 leaves the target area, etc. At this time, the roller brush motor 131 and the lighting module 1310 stop working. At the same time, the vacuum sensor 1371 can continue to monitor the vacuum degree. In addition, when the power of the battery pack 1341 obtained by the power indication module 136 is greater than or equal to C, it indicates that the battery pack 1341 has sufficient power, otherwise an alarm signal is issued.

[0095] In one embodiment, please refer to Figure 14 , the switch detection module 138 detects whether the switch of the cleaner head 130 is turned on. After the switch of the vacuum cleaner is turned on, the following steps are carried out. The power of the battery pack 1341 obtained by the power indication module 136 is obtained, and the vacuum sensor 1371 in the vacuum degree monitoring module 137 monitors the vacuum degree.

[0096] When the vacuum degree value monitored by the vacuum sensor 1371 is greater than A, timing is started. When the vacuum degree value is greater than A and lasts for more than T time, it indicates that the vacuum motor 111 of the vacuum cleaner starts normally, and the bottom surface of the cleaner head 130 contacts the target area. At this time, the roller brush motor 131 starts and the lighting module 1310 lights up to perform the cleaning work. When the vacuum degree value is greater than A but does not last for more than T time, the vacuum sensor 1371 is controlled to continue monitoring the vacuum degree. When the vacuum degree value is less than or equal to A and lasts for more than B time, it indicates that the vacuum motor 111 of the vacuum cleaner is abnormal, or the bottom surface of the cleaner head 130 leaves the target area. At this time, the roller brush motor 131, the lighting module 1310 and the vacuum sensor 1371 stop working. Or, the vacuum sensor 1371 can also continue to monitor the vacuum degree until the vacuum degree value is greater than A.

[0097] When the switch detection module 138 detects that the switch of the vacuum cleaner is turned off, the roller brush motor 131, the lighting module 1310, and the vacuum degree sensor 1371 stop working. In addition, when the power of the battery pack 1341 obtained by the power indication module 136 is greater than or equal to C, it indicates that the battery pack 1341 has sufficient power; otherwise, an alarm signal is sent and the roller brush motor 131, the lighting module 1310, and the vacuum degree sensor 1371 stop working.
