Description

Technical Field

[0001] The utility model relates to the technical field of cleaning, in particular to a vacuum cleaner system. Background Art

[0002] Among indoor cleaning tools, AC upright vacuum cleaners (AC Uprightvacuum) that use AC power as an energy source are widely used for whole-house cleaning because of their high-power (greater than or equal to 1000W) negative pressure blower and large-capacity (greater than or equal to 1L) dust box. They have high cleaning and dust removal efficiency (especially for soft floors, such as carpets). However, because they must use AC power, they need to drag a long power cord when working, which is inconvenient to move; and because they also need to take into account the cleaning of three-dimensional working surfaces (such as sofas, stairs, curtains), the dust and gas flow of the main machine needs to pass through roller brushes, hard pipes, hoses, dust boxes, and blowers. The flow path is very long, and the energy loss of gas along the flow path is very large, and the energy efficiency is low.

[0003] As an improvement, DC handheld vacuum cleaners (DC stickvacuum) that use batteries as energy sources have appeared on the market. They have the advantages of no power cord, small size, light weight, and easy mobility. However, the current DC handheld vacuum cleaners have a single function and cannot be applied to different cleaning scenarios. For example, a vacuum cleaner for floor cleaning is not suitable for cleaning at high places. Moreover, the dust and gas flow path of the current DC handheld vacuum cleaners is still very long, the energy loss is still large when the gas flows along the flow path, and the energy efficiency is still low. At present, the total power of DC handheld vacuum cleaners with good dust collection performance is above 450W. However, due to the constraints of current battery technology, the energy density of the battery cell (energy stored per unit volume), the total energy stored in the DC handheld vacuum cleaner battery pack is limited. At maximum power, the battery life of the DC handheld vacuum cleaner is short, generally only about 15 minutes, which cannot meet the needs of whole house cleaning. Utility Model Content

[0057] Embodiment 1

[0058] The present application provides a vacuum cleaner system, such as Figure 1 or Fig. 9 As shown, the vacuum cleaner system includes: a first cleaning head 1; a second cleaning head 2; a dust box 41, which is used to collect dust cleaned by the first cleaning head 1 or the second cleaning head 2; a fan 42, which can suck airflow, and is used to suck the dust cleaned by the first cleaning head 1 or the second cleaning head 2 into the dust box 41; a handle module 5, which includes a shell having a handle 51 and a power supply 52 installed on the shell 51;

[0059] like Figure 6 or Fig.10 As shown, the first cleaning head 1 can be connected and combined with the fan 42, the dust box 41 and the handle module 5 to form a first dust collection tool;

[0060] like Figure 8 or Fig.11 As shown, the second cleaning head 2 can be connected and combined with the fan 42, the dust box 41 and the handle module 5 to form a second dust collection tool;

[0061] like Figure 6 or Fig.10 As shown, in the first vacuum tool, the fan 42 is adapted to be installed in the first position. In the first position, the fan 42 is closer to the first cleaning head 1 relative to the handle module 5; Figure 8 or Fig.11 As shown, in the second vacuum tool, the fan 42 is adapted to be installed in the second position. In the second position, the fan 42 is closer to the handle module 5 relative to the second cleaning head 2 .

[0062] The vacuum cleaner system provided in the present application uses a variety of different cleaning heads for different cleaning scenarios, and the fans are correspondingly arranged at different installation positions, so that the vacuum cleaner system can adapt to various cleaning scenarios, that is, the components in the vacuum cleaner system can be freely combined according to the user's needs for the cleaning scene, which is convenient for user operation and realizes efficient cleaning.

[0063] When the user needs to clean the floor A, the first cleaning head can be connected with the fan, the dust box and the handle module to form a first vacuuming tool, wherein the fan is arranged closer to the first cleaning head, so that the user can operate the handle module more labor-savingly. At the same time, since the fan is closer to the first cleaning head, that is, the fan is closer to the air inlet on the first cleaning head, the airflow path of the whole machine is short, which is conducive to reducing energy loss, thereby achieving efficient cleaning;

[0064] When the user needs to clean step surface B, the second cleaning head can be connected with the fan, dust box and handle module to form a second vacuuming tool, in which the fan is arranged closer to the handle module, and the user can operate the second cleaning head more conveniently and flexibly. At the same time, when cleaning step surface B, the vacuuming tool is expected to be smaller and more flexible for user operation. The handle module should not be far away from the second cleaning head. Although the fan is positioned closer to the handle module, in order to ensure flexible operation, the fan and the handle module are closer to the second cleaning head, so that the fan is still arranged relatively close to the second cleaning head, thereby shortening the airflow path of the whole machine, reducing energy loss, and achieving efficient cleaning.

[0065] In one embodiment, Figure 1 or Fig. 9 As shown, a filter 43 is usually provided in the dust box 41. Under the suction action of the fan 42, the air flow mixed with dust or impurities entering from the air inlet 411 of the dust box 41 is filtered by the filter 43 and discharged from the air outlet, and the filtered dust and impurities remain in the dust box 41.

[0066] In one embodiment, Figure 1 or Fig. 9 , Figure 3 , Figure 6 or Fig.10 As shown, the dust box 41 and the fan 42 are modularly combined to form a dust collecting module 4. In the first dust collecting tool, the dust collecting module 4 is adapted to be installed in the first position; Figure 8 or Fig.11 As shown, in the second type of dust collection tool, the dust collection module 4 is adapted to be installed in the second position. This arrangement allows the dust box and the fan to be modularized, which is more convenient for users to assemble or disassemble the dust collection tool.

[0067] In one embodiment, Figure 6 or Fig.10As shown, in the first vacuum cleaner, the first position is located in the first cleaning head 1. This arrangement makes the fan closer to the air inlet of the first cleaning head, so that the airflow path of the whole machine is short, which is conducive to reducing energy loss, thereby achieving efficient cleaning.

[0068] Alternatively, if Figure 6 As shown, the vacuum cleaner system also includes a first connecting tube 8 and a first adapter 6 that can be connected to the first connecting tube 8, and the first adapter 6 has a connection port for electrically connecting to the handle module 5; wherein one end of the first connecting tube 8 is electrically connected to the first cleaning head 1, and the other end is electrically connected to the handle module 5 through the first adapter 6, thereby forming a first vacuum cleaner tool in combination.

[0069] Specifically, Figure 6 and Figure 7 As shown, the dust collecting module 4 is arranged in the first cleaning head 1, and the first cleaning head 1 is connected with a first connecting tube 8, and one end of the first connecting tube 8 away from the first cleaning head 1 is connected to the handle module 5 through a first adapter 6. Since a double roller brush mechanism 12 is arranged in the first cleaning head 1, the double roller brush mechanism 12 needs to be driven by electric energy, and the fan 42 of the dust collecting module 4 installed in the first cleaning head 1 needs to be driven by electric energy, an electric wire is arranged in the first connecting tube 8, one end of the first connecting tube 8 is electrically connected to the power supply 52 of the handle module 5 through the first adapter 6, and the other end is electrically connected to the first cleaning head 1.

[0070] More specifically, Figure 5 As shown, the first adapter 6 is provided with a tube interface 61 for connecting to the first connecting tube 8, and is also provided with a first connection port 62 and a second connection port 63; the handle module 5 is provided with a shell having a handle 51, a power supply 52 is installed on the shell, and a third connection port 53 and a fourth connection port 54 are also provided on the shell. The first connection port 62 of the first adapter 6 can be electrically connected to the third connection port 53 on the handle module 5 through an electrical connection terminal, and the second connection port 63 and the fourth connection port 54 can be provided with a snap-fitting structure that can cooperate with the snap-fitting, so that the first adapter 6 and the handle module 5 can be snap-fitted and fixed together while being electrically connected, thereby, the power supply 52 of the handle module 5 can supply power to the first cleaning head 1.

[0071] Alternatively, if Fig.10 As shown, the vacuum cleaner system also includes a first connecting tube 8 and a second connecting tube 9, and one end of the second connecting tube 9 is provided with a connecting port (not shown) and a cover 91; wherein, one end of the first connecting tube 8 is electrically connected to the first cleaning head 1, and the other end is electrically connected to the other end of the second connecting tube 9, the connecting port (not shown) is electrically connected to the handle module 5, and the cover 91 covers the connection between the second connecting tube 9 and the handle module 5, thereby forming a first type of vacuum cleaner tool in combination.

[0072] In one embodiment, Figure 8 As shown, the vacuum cleaner system also includes a second connecting tube 9 and a second adapter 7 that can be connected to the second connecting tube 9, and the second adapter 7 has an air outlet interface 71; wherein, one end of the second connecting tube 9 is connected to the second cleaning head 2, and the other end is connected to the air inlet (not shown) of the dust collection module 4 through the air outlet interface 71 of the second adapter 7, and the dust collection module 4 is directly connected to the handle module 5 to form a second vacuum tool in combination.

[0073] Optionally, the second connecting tube 9 and the second adapter 7 can be fixed together. When assembling the vacuum cleaner tool, the second connecting tube 9 and the second adapter 7 are installed and used as a whole. Of course, the second connecting tube 9 and the second adapter 7 can also be designed separately. When in use, the second adapter 7 can be assembled with the second connecting tube 9 or assembled with the first connecting tube 8 and used.

[0074] Specifically, Figure 8 As shown, the second vacuuming tool formed by the combination includes a second cleaning head 2 and a second connecting pipe 9 connected to the second cleaning head 2, and also includes a handle module 5 and a dust collecting module 4 installed on the handle module 5. The second connecting pipe 9 is connected to the dust box 41 of the dust collecting module 4 through a second adapter 7. When the fan 42 of the dust collecting module 4 is working, the second cleaning head 2 can suck dust, so that the dust enters the dust box 41 of the dust collecting module 4 from the second cleaning head 2 along the second connecting pipe 9. In this embodiment, the second vacuuming tool is suitable for cleaning the step surface B. When the user cleans the step surface B, the dust collecting module is installed close to the handle module, and the second cleaning head is lighter and more flexible when operating. At the same time, the shorter second connecting pipe makes it easier for the user to clean the step surface B, and also makes the dust suction path short and the air volume loss small.

[0075] In one embodiment, Fig.11 As shown, the vacuum cleaner system also includes a second connecting tube 9, one end of which is provided with a connecting port (not shown) and a cover 91; wherein the other end of the second connecting tube 9 is electrically connected to the second cleaning head 2, the connecting port (not shown) is electrically connected to the dust collecting module 4, the cover 91 covers the connection between the second connecting tube 9 and the dust collecting module 4, and the dust collecting module 4 is directly connected to the handle module 5 to form a second vacuum cleaner tool.

[0076] Furthermore, the cover 91 is also configured so that when the dust collecting module 4 is installed in the second position, the cover 91 can dock with the air inlet 411 of the dust box 41.

[0077] In summary, if Figure 1As shown, a vacuum cleaner system in one embodiment includes a first cleaning head 1, a second cleaning head 2, a dust box 41, a fan 42 and a handle module 5, and also includes a first connecting pipe 8, a first adapter 6 connected to the first connecting pipe 8, a second connecting pipe 9, and a second adapter 7 connected to the second connecting pipe 9, and the second adapter 7 has an air outlet interface 71. Figure 1 The parts shown can be combined to form Figure 6 and Figure 8 The vacuuming tools shown are used in different scenarios.

[0078] Scene 1

[0079] When the user needs to clean the floor A, Figure 6 The dust box 41 and the fan 42 are modularized into a dust collection module 4 and arranged in the first cleaning head 1. The first cleaning head 1 is connected to the first connecting pipe 8, and the first connecting pipe 8 is electrically connected to the handle module 5 through the first adapter 6. Since the dust collection module is arranged in the first cleaning head, it is convenient for the user to operate the handle module, and the dust collection module is closer to the air inlet of the first cleaning head, so that the airflow path of the whole machine is short, which is conducive to reducing energy loss, thereby achieving efficient cleaning.

[0080] Scene 2

[0081] When the user needs to clean the step surface B, Figure 8 The dust box 41 and the fan 42 are modularized into a dust collection module 4 and are directly connected to the handle module 5. The second cleaning head 8 is connected to the second connecting pipe 9, and the second connecting pipe 9 is connected to the dust collection module 4 and the handle module 5 in sequence through the second adapter 7. Since the dust collection module is arranged on the handle module, the operation of the second cleaning head is lighter and more flexible. In this cleaning scenario, in order to facilitate the user's operation, the second connecting pipe should not be too long, so that the distance between the dust collection module and the second cleaning head is also short, so that the airflow path of the whole machine is short, which is conducive to reducing energy loss, thereby achieving efficient cleaning.

[0082] In summary, if Fig. 9 As shown, a vacuum cleaner system in another embodiment includes a first cleaning head 1, a second cleaning head 2, a dust box 41, a fan 42 and a handle module 5, and also includes a first connecting tube 8 and a second connecting tube 9 with a cover 91, and a connection port electrically connected to the handle module 5 is provided in the cover 91. Fig. 9 The parts shown can be combined to form Fig.10 and Fig.11 The vacuuming tools shown are used in different scenarios.

[0083] Fig. 9Among the components of the vacuum cleaner shown, each cleaning head needs to be connected to the handle module 5 , and needs to be connected to the handle module 5 through the connection port on the second connection 9 and the cover 91 .

[0084] Scene 1

[0085] When the user needs to clean the floor A, Fig.10 The dust box 41 and the fan 42 are modularized into a dust collection module 4 and arranged in the first cleaning head 1. The first cleaning head 1 is connected to the first connecting pipe 8, and the first connecting pipe 8 is connected to the second connecting pipe 9. The second connecting pipe 9 is electrically connected to the handle module 5 through the connecting port thereon, and the cover 91 covers the connection between the second connecting pipe 9 and the handle module 5. The first vacuum cleaner here is also suitable for cleaning the floor, and the corresponding advantages are the same as Figure 6 The implementation method in is similar and will not be repeated here.

[0086] Scene 2

[0087] When the user needs to clean the step surface B, Fig.11 The dust box 41 and the fan 42 are modularized into a dust collection module 4 and are directly connected to the handle module 5. The second cleaning head 2 is connected to the second connecting pipe 9, and the second connecting pipe 9 is electrically connected to the handle module 5 through the connecting port thereon. The cover 91 covers the connection between the second connecting pipe 9 and the handle module 5. The second vacuum cleaner here is also suitable for cleaning step surfaces, and the corresponding advantages are the same as those of the second vacuum cleaner. Figure 8 The implementation method in is similar and will not be repeated here.

[0088] In one embodiment, Figure 2 As shown, the first cleaning head 1 includes: a first shell 11 and a double roller brush mechanism 12 and at least two first support wheels 14 installed on the first shell 11. The first cleaning head 1 can be supported on the ground by the first support wheels 14. The double roller brush mechanism 12 includes two first roller brushes that can rotate relative to each other, which are used to clean dust on the ground through the relative rotation of the two first roller brushes.

[0089] Furthermore, the two first roller brushes are installed on the roller brush frame. In order to improve the dust absorption capacity, a movable sealing door can be provided on the roller brush frame. The movable sealing door can seal the space in the forward direction of the roller brush when sweeping the floor to improve the cleaning efficiency. When there is large-sized particulate garbage in the front, the controller can control the movable sealing door to open.

[0090] Specifically, Figure 2 , Figure 6 and Fig.10As shown, the first cleaning head 1 has a hinged first connecting portion 15; the vacuum cleaner system also includes a first connecting pipe 8. In the first vacuum cleaner tool, the dust collecting module 4 is installed close to the first cleaning head 1, and more specifically, the dust collecting module 4 is arranged in the first cleaning head 1; the dust cleaned by the roller brush mechanism 12 can enter the dust box 41 through the air duct 13 under the action of the fan 42. One end of the first connecting pipe 8 is electrically connected to the first connecting portion 15, and the other end is connected to the dust box 41 through the first adapter 6 (such as Figure 6 as shown) or the second connecting pipe 9 (as shown Fig.10 As shown in the figure, it is electrically connected to the handle module 5, so that the power supply 52 of the handle module 5 can supply power to the first cleaning head 1, so that the dual roller brush mechanism 12 and the fan 42 are in operation.

[0091] In this embodiment, a first vacuum cleaner is formed by combining a first cleaning head 1. Since the first connecting portion 15 is hinged, the first connecting tube 8 can rotate relative to the first cleaning head 1, so that Figure 7 As shown, while holding the handle 51 for cleaning, the handle module 5 and the first connecting tube 8 can be rotated relative to the first cleaning head 1 as needed, and can be rotated until the first connecting tube 8 is parallel to the ground A. At this time, the first cleaning head 1 can be extended into low places such as under a bed or sofa for cleaning.

[0092] In one embodiment, Figure 4 As shown, the second cleaning head 2 comprises: a second shell 21 , a second roller brush 22 installed in the second shell 21 , and at least two second supporting wheels 24 . The second cleaning head 2 can be supported on the ground by the second supporting wheels 24 .

[0093] Furthermore, the second cleaning head 2 has a hinged second connecting portion 23; the vacuum cleaner system further comprises a second connecting pipe 9; in the second vacuum cleaner tool, as Figure 8 or Fig.11 As shown, the dust collection module 4 is installed close to the handle module 5. More specifically, the dust collection module 4 is directly connected to the handle module 5. One end of the second connecting pipe 9 is connected to the second connecting portion 23 of the second cleaning head 2, and the other end is connected to the second cleaning head 2 through the second adapter 7 (as shown in FIG. Figure 8 As shown) or cover 91 (as Fig.11 As shown) is docked with the air inlet of the dust box 41 of the dust collecting module 4. When the fan 42 of the dust collecting module 4 is working, the dust cleaned by the second roller brush 22 of the second cleaning head 2 can enter the dust box 41 along the second connecting pipe 9.

[0094] In one embodiment, a control unit may be further provided in the handle module 5 to control the operation of the fan 42 of the dust collection module 4 and the roller brush in the cleaning head.

[0095] Those skilled in the art will appreciate that the structure of each cleaning head and the connection position of the fan are not limited to those described above, and may have various modifications without departing from the scope of protection of the present application. In addition, each cleaning head, fan, dust box and handle module may have more combination modes when using connecting accessories (i.e., connecting tubes), which are not listed here one by one.

[0096] In one embodiment, the total length of the air path of at least one vacuum tool is less than or equal to 0.6 meters.

[0097] Specifically, Figure 6 or Fig.10 In the first vacuum cleaner tool suitable for floor cleaning, the dust collecting module 4 is installed in the first cleaning head 1. Under the negative pressure of the fan 42, the dust cleaned by the double roller brush mechanism 12 of the first cleaning head 1 enters the dust box 41 through the air duct 13, and then is discharged after being filtered by the filter 43 in the dust box 41. The total length of the air path is short, less than or equal to 0.6 meters. The short air path of the first vacuum cleaner tool is conducive to reducing energy loss, thereby achieving efficient cleaning.

[0098] Figure 8 or Fig.11 The second vacuum tool suitable for step surface cleaning is formed by the combination, and the dust collecting module 4 is directly connected to the handle module 5. In order to facilitate the cleaning of the step surface, the dust collecting module 4 is connected to the second cleaning head 2 through a shorter second connecting pipe 9. Under the negative pressure of the fan 42, the dust cleaned by the roller brush of the second cleaning head 2 enters the dust box 41 through the second connecting pipe 9, and then is discharged after being filtered by the filter 43 in the dust box 41. The total length of the air path is relatively short, and the total length of the air path is less than or equal to 0.8 meters.

[0099] In one embodiment, since the total length of the gas path is short and the energy consumption is small, the total power P of each vacuum cleaner is ≤ 200 W. Optionally, the total power is 110 W ≤ P ≤ 150 W. In this way, a certain endurance can be guaranteed when powered by a battery pack.

[0100] In one embodiment, Figure 6 and Figure 7 The first vacuum tool suitable for floor cleaning has a power of P1 ≥ 60 W, more preferably P1 ≥ 80 W. The power of the fan 42 can ensure sufficient vacuuming capacity. In this embodiment, the total power of the fan 42 + double roller brush mechanism 102 is: 85 W ≤ P ≤ 200 W, optionally, 110 W ≤ P ≤ 150 W.

[0101] According to another aspect of the present application, Fig.24 As shown, a vacuum cleaner device is also provided, the vacuum cleaner device includes a base station 70 and the vacuum cleaner system as described above;

[0102] The base station 70 includes a base station body 701 and a dust suction fan 702. A garbage bin 703 and an air intake channel 704 connected to the garbage bin 703 are formed in the base station body 701.

[0103] The dust box 41 is configured to be installed on the base station 70 , and the air inlet of the dust box 41 corresponds to the air inlet channel 704 , so that when the dust box 41 is installed on the base station 70 , the dust suction fan 702 can suck the dust in the dust box 41 into the garbage bin 703 .

[0104] In one embodiment, if Fig.24 As shown, when the dust box 41 and the fan 42 are modularized into the dust collecting module 4, the entire dust collecting module 4 can be installed on the base station 70. When the dust box 41 and the fan 42 are separable, only the dust box 41 can be installed on the base station 70.

[0105] When cleaning dust, a vacuuming tool that is suitable for the scene to be cleaned is assembled. After vacuuming is completed, the dust box 41 is removed and installed on the base station 70. After the vacuuming fan 702 of the base station 70 is running, the dust and garbage in the dust box 41 can be sucked into the garbage bin 703 of the base station. The garbage in the garbage bin 703 can be cleaned after it accumulates to a certain level.

[0106] In one embodiment, the base station body 701 is further provided with a storage bin (not shown) located above the garbage bin 703, and the storage bin is used to store at least part of the cleaning head, the connecting pipe, the dust collection module and the handle module.

[0107] Embodiment 2

[0108] The vacuum cleaner system in this embodiment is similar to the vacuum cleaner system in the first embodiment, and the difference from the first embodiment is that the dust box and the fan are two independent modules, and the fan can be installed in different positions according to different cleaning scenarios. Unless otherwise specified, the structure of the vacuum cleaner system in the second embodiment is the same as that in the first embodiment, and will not be repeated.

[0109] The present application provides a vacuum cleaner system in another embodiment, such as Fig.12 As shown, it includes: a first cleaning head 10; a second cleaning head 20; a dust box for collecting dust cleaned by the first cleaning head 10 or the second cleaning head 20; a fan 40, which can suck airflow and suck the dust cleaned by the first cleaning head 10 or the second cleaning head 20 into the dust box; a handle module 50, which includes a shell having a handle 501 and a power supply 502 installed on the shell;

[0110] like Fig.18 and Fig.21As shown, the first cleaning head 10 can be connected and combined with the fan 40, the dust box and the handle module 50 to form a first vacuuming tool;

[0111] like Fig. 22 As shown, the second cleaning head 20 can be connected and combined with the fan 40, the dust box and the handle module 50 to form a second dust collection tool;

[0112] like Fig.18 and Fig.21 As shown, in the first vacuum tool, the fan 40 is adapted to be installed in the first position. In the first position, the fan 40 is closer to the first cleaning head 10 relative to the handle module 50; Fig. 22 As shown, in the second vacuum tool, the fan 40 is adapted to be installed in the second position. In the second position, the fan 40 is closer to the handle module 50 relative to the second cleaning head 20 .

[0113] The vacuum cleaner system in this embodiment is similar to the vacuum cleaner system in the first embodiment. The first vacuum cleaner tool is suitable for floor cleaning, and the second vacuum cleaner tool is suitable for step cleaning. A variety of different cleaning heads can be used for different cleaning scenes, and the fan can be set at different installation positions accordingly, so that the vacuum cleaner system can adapt to various cleaning scenes, facilitate user operation, and achieve efficient cleaning. The advantages of such a layout are similar to those in the first embodiment and will not be repeated.

[0114] In one embodiment, Fig.16 As shown, the fan 40 includes a fan housing 401 and a fan 402 located in the fan housing 401. The fan housing 401 is provided with an air suction port 4011 and an air exhaust port 4012. The air suction port 4011 can be connected to the dust box to suck the dust cleaned by each cleaning head into the dust box. An electrical connection port 4013 can also be provided on the fan housing 401 for directly or indirectly electrically connecting to the power supply of the handle module 50.

[0115] In one embodiment, Fig.17 As shown, the handle module 50 includes a shell having a handle 501 and a power supply 502 mounted on the shell. The power supply 502 can supply power to the fan and the roller brush of the cleaning head (if a roller brush is provided).

[0116] In one embodiment, if Fig.21 As shown, in the first position, the fan 40 is located in the first cleaning head. Such a layout makes the fan closer to the air inlet of the cleaning head, so that the total length of the air path is short, the energy consumption is small, and efficient cleaning can be achieved.

[0117] Furthermore, if Fig.21As shown, the dust box 104 is located in the first cleaning head 10, and the vacuum cleaner system also includes a connecting tube 60. A first connecting part 106 is hinged on the first cleaning head 10. One end of the connecting tube 60 away from the handle module 50 is electrically connected to the first connecting part 106, and the other end is electrically connected to the handle module 50, thereby forming a first vacuum cleaner tool.

[0118] Specifically, such as 13 and Fig.21 As shown, in the first vacuuming tool, the dust box is a first dust box 104 fixedly arranged in the first cleaning head 10 and adapted to the first cleaning head 10. The first dust box 104 is used to collect dust cleaned by the first cleaning head 10. In the direction of airflow, the first dust box 104 is located upstream of the fan 40. Optionally, the first dust box 104 can also be detachably arranged in the first cleaning head 10, so that the user can disassemble and clean it conveniently. A first connecting part 106 is hinged on the first cleaning head 10, and a connecting tube 60 is connected between the first connecting part 106 and the handle module 50. The fan 40 is installed in the first cleaning head 10. The electrical connection port 4013 of the fan 40 can be electrically connected to the power supply of the handle module 50 through the first connecting part 106 and the connecting tube 60. The air suction port 4011 of the fan 40 is connected to the air outlet of the first dust box 104 of the first cleaning head 10 to provide negative pressure to the first dust box 104, so that the dust cleaned by the first cleaning head 10 enters the first dust box 104 under the action of the fan 40.

[0119] In one embodiment, if Fig.18 As shown, the fan 40 is located between the first cleaning head 10 and the handle module 50. Such a layout makes it possible for the fan to be not arranged in the cleaning head, so as not to cause the cleaning head to be bulky and interfere with cleaning low places.

[0120] Among them, Fig.13 As shown, the dust box is a first dust box 104 adapted to the first cleaning head 10, and is arranged in the first cleaning head 10. Optionally, the first dust box 104 is not arranged in the first cleaning head 10, but is arranged between the first cleaning head 10 and the handle module 50, but in the direction of airflow, the first dust box 104 is located upstream of the fan 40.

[0121] Furthermore, if Fig.18 and Fig.19 As shown, the vacuum cleaner system also includes a connecting tube 60 arranged between the first cleaning head 10 and the handle module 50. When in the first position, the fan 40 is located between the first cleaning head 10 and the connecting tube 60; wherein the first cleaning head 10, the fan 40, the connecting tube 60 and the handle module 50 are electrically connected in sequence to form a first vacuum cleaner tool.

[0122] Furthermore, if Fig.18 and Fig.19As shown, a first connecting portion 106 is hingedly connected to the first cleaning head 10 , and the fan 40 is connected between the first connecting portion 106 and the connecting pipe 60 . Fig.21 In the first vacuum cleaner shown in FIG. 1 , the fan 40 is installed in the first cleaning head 10. Most of the weight is concentrated in the first cleaning head 10. As a hand-held vacuum cleaner, the fan 40 has good stability. However, if the first cleaning head 10 needs to be extended into a low place such as the bottom of a bed or a sofa for cleaning, the fan 40 may interfere. In this case, the fan 40 can be removed from the first cleaning head 10. Fig.18 and Fig.19 As shown in FIG. 1 , the fan 40 is installed between the first connecting portion 106 and the connecting pipe 60 . At this time, the first cleaning head 10 is relatively small in size and can be suitable for extending into a narrow area for cleaning.

[0123] Specifically, Fig.18 and Fig.19 In the first vacuuming tool shown, a first connecting part 106 is hinged on the first cleaning head 10, and a fan 40 is connected between the first connecting part 106 and the connecting tube 60, wherein the fan 40 is electrically connected to the connecting tube 60 via an electrical connection port 4013, and an electric wire electrically connected to a power supply 502 in the handle module 50 may be arranged in the connecting tube 60, and an air suction port 4011 of the fan 40 is connected to the first connecting part 106, and the first connecting part 106 is connected to the cleaning part of the first cleaning head 10 in airflow communication, so that the dust and garbage cleaned by the first cleaning head 10 enters the first dust box 104 of the first cleaning head 10 under the negative pressure of the fan 40.

[0124] In one embodiment, if Fig. 22 As shown, the fan 40 is located between the second cleaning head 20 and the handle module 50. Such a layout makes it possible for the second cleaning head to not bear the weight of the fan when the user needs to clean the step surface, and the operation is more convenient and flexible.

[0125] Furthermore, if Fig. 22 As shown, a connecting portion 206 is hinged on the second cleaning head 20. In the second position, the fan 40 is directly connected to the handle module 50, and the air suction port 4011 of the fan is connected to the connecting portion 206 to form a second vacuuming tool.

[0126] Specifically, Fig.14 and Fig. 22The second dust collecting tool shown is suitable for cleaning the step surface B, wherein the dust box is a second dust box 204 adapted to the second cleaning head 20, and is arranged in the second cleaning head 20. Optionally, the second dust box 204 is not arranged in the second cleaning head 20, but is arranged between the second cleaning head 20 and the handle module 50, but in the direction of air flow, the second dust box 204 is located upstream of the fan 40. The second cleaning head 20 is provided with a second connecting portion 206, and the fan 40 is directly connected to the handle module 50 through the electrical connection port 4013. The air suction port 4011 of the fan 40 is connected to the second connecting portion 206, and the air suction port 4011 of the fan 40 can also be connected to the second connecting portion 206 through the connecting pipe 60 to extend the distance between the handle module 50 and the second cleaning head 20.

[0127] In one embodiment, if Fig.23 As shown, the vacuum cleaner system also includes a third cleaning head 30 and a connecting tube 60, the fan 40 is connected to the end of the connecting tube 60 away from the handle module 50, and the air suction port 4011 of the fan 40 is connected to the air outlet of the third cleaning head 30, thereby forming a third vacuum cleaner tool.

[0128] Furthermore, if Fig.15 As shown, the third cleaning head 30 includes a third shell 301 which is hollow inside and has an inlet 3011 and an outlet (not shown). The inlet 3011 is used to absorb dust, and the outlet is connected to the air inlet 4011 of the fan 40. Under the action of the fan 40, the dust absorbed by the inlet 3011 can enter the third dust box 302.

[0129] Among them, in this embodiment, if Fig.15 As shown, the dust box is a third dust box 302 adapted to the third cleaning head 30, and is arranged in the third cleaning head 30. Optionally, the third dust box 302 is not arranged in the third cleaning head 30, but is arranged between the third cleaning head 30 and the handle module 50, but in the direction of airflow, the third dust box 302 is located upstream of the fan 40.

[0130] Specifically, Fig.23 In the third vacuuming tool shown in FIG. 3 , the fan 40 is connected between the third cleaning head 30 and the connecting tube 60. More specifically, the electrical connection port 4013 of the fan 40 is connected to the end of the connecting tube 60 away from the handle module 50, and is electrically connected to the power supply of the handle module 50 through the connecting tube 60. The air suction port 4011 of the fan 40 is docked with the air outlet of the third dust collection box 302 of the third cleaning head 30, so that under the negative pressure of the fan 40, the dust adsorbed by the inlet 3011 of the third cleaning head 30 enters the third dust collection box 302.

[0131] In summary, if Fig.12As shown, a vacuum cleaner system in another embodiment includes a first cleaning head 10, a second cleaning head 20, a third cleaning head 30, a fan 40, a handle module 50 and a connecting pipe 60. Fig.12 The parts shown can be combined to form Fig.18 , Figure 21-23 The vacuuming tools shown are used in different cleaning scenarios.

[0132] Scene 1

[0133] When the user needs to clean floor A or low floors, Fig.18 The first dust box 104 and the fan 40 are two independent modules. The first dust box 104 is arranged in the first cleaning head 10. The first cleaning head 1 is connected to the fan 40 through the first connecting part 106. The fan 40 is electrically connected to the handle module 5 through the connecting tube 60. In this combination, since the fan is arranged close to the first cleaning head, it is convenient for the user to operate the handle module, so that the airflow path of the whole machine is short, which is conducive to reducing energy loss, thereby achieving efficient cleaning. At the same time, the fan is not arranged in the first cleaning head, so that the volume of the first cleaning head will not be affected by the fan, and the first cleaning head can be miniaturized, which is convenient for cleaning low places (such as Fig.19 shown).

[0134] Scene 2

[0135] When the user needs to clean the floor A, Fig.21 The first dust box 104 and the fan 40 are two independent modules, both of which are arranged in the first cleaning head 10 and are electrically connected through the first connecting portion 106, the connecting pipe 60 and the handle module 50. The dust box and the fan of the first vacuum cleaner tool are both arranged in the cleaning head, which has better stability when the user cleans the floor, and also makes the airflow path of the whole machine short, which is conducive to reducing energy loss, thereby achieving efficient cleaning.

[0136] Scene 3

[0137] When the user needs to clean the step surface B, Fig. 22 The second dust box 204 and the fan 40 are two independent modules. The second dust box 204 is arranged in the second cleaning head 20. The second cleaning head 20 is connected to the fan 40 through the second connecting portion 206. The fan 40 is directly connected to the handle module 50. Since the fan is arranged on the handle module, the operation of the second cleaning head is more convenient and flexible. In this cleaning scene, in order to facilitate the operation of the user, the distance between the fan and the second cleaning head is also short, so that the airflow path of the whole machine is short, which is conducive to reducing energy loss, thereby achieving efficient cleaning.

[0138] Scene 4

[0139] When the user needs to clean the high wall surface C, Fig.23 The third dust box 302 and the fan 40 are two independent modules. The third dust box 302 is arranged in the third cleaning head 30, and the fan 40 is arranged at the end of the connecting pipe 60 away from the handle module 50. Since the fan is arranged close to the third cleaning head, the airflow path of the whole machine is short, which is conducive to reducing energy loss, thereby achieving efficient cleaning.

[0140] Those skilled in the art will appreciate that the structure of each cleaning head and the connection position of the fan are not limited to those described above, and may have various modifications without departing from the scope of protection of the present application. In addition, each cleaning head, negative pressure module and handle module may have more combination modes when using connecting accessories (i.e., connecting tubes), which are not listed here one by one.

[0141] In the vacuum cleaner system provided in the present application, the total air path length of each vacuum cleaner tool is less than or equal to 1.2 meters, and the total air path length of at least one vacuum cleaner tool is less than or equal to 0.6 meters.

[0142] Fig.18 and Fig.21 The first vacuum cleaner suitable for floor cleaning formed by the combination of Fig. 22 A second vacuuming tool suitable for step surface cleaning is formed by combining Fig.23 The third vacuuming tool formed by the middle combination is suitable for high-place cleaning. Since the fans 40 are close to the dust boxes of each cleaning head, the total length of the air path is short, less than or equal to 0.8 meters, which is conducive to reducing energy loss and thus achieving the highest cleaning efficiency.

[0143] Wherein, the total length of the air path of at least one vacuum cleaner is less than or equal to 0.6 meters. Fig.21 and Fig.23 A dust collection tool in which the blower 40 is directly connected to the dust box.
