Hereinafter, a cleaning apparatus 1 according to an embodiment of the present invention is described with reference to fig. 1 to 10.

As shown in fig. 1 and 2, a cleaning apparatus 1 according to an embodiment of the present invention may include: a handset assembly 11 and a stand assembly 12, wherein the handset assembly 11 includes a handle 114 adapted to be held, the handset assembly 11 includes a dust cup assembly 111 and a first suction device 112, the stand assembly 12 includes a body assembly 121 and a second suction device 122, the body assembly 121 includes a push rod 1211 and a floor brush 1212 connected to a lower end of the push rod 1211, when a user pushes an upper end of the push rod 1211, the lower end of the push rod 1211 can drive the floor brush 1212 to travel on a traveling surface, and the floor brush 1212 has a dust suction opening 12120 for sucking a dust-containing air flow and a roller 1213 adapted to travel on the traveling surface. The handset assembly 11 is detachably connected to the upright assembly 12 so that the cleaning device 1 is provided with a handheld operating state and an upright operating state, that is to say, the cleaning device 1 can be changed into a handheld operating state and the cleaning device 1 can be changed into an upright operating state.

As shown in fig. 2, in a handheld operating state, the handset assembly 11 is detached from the upright assembly 12, and the first suction device 112 operates to suck the airflow into the dirt cup assembly 111 and remove the dirt. That is, in the hand-held operation state, the hand-held assembly 11 is detached from the upright machine assembly 12, and the cleaning work is performed using the hand-held assembly 11, at this time, the dust-containing air flow can be sucked by using the first suction device 112 as the suction source, and the dust removal can be performed by using the dust cup assembly 111.

As shown in fig. 1, in the upright operating state, the handset assembly 11 is mounted on the upright assembly 12, and at least one of the first suction device 112 and the second suction device 122 operates to cause the floor brush 1212 to draw in an airflow and deliver it to the dirt cup assembly 111 for removal of dirt. That is, in the upright operating state, the handset assembly 11 and the upright assembly 12 are combined together, and the user can grasp the upright assembly 12 to perform cleaning operation, at this time, at least one of the first suction device 112 and the second suction device 122 can be used as a suction source to suck the dust-containing air flow into the floor brush 1212, and then the dust cup assembly 111 on the handset assembly 11 is used to perform dust removal operation.

Thus, according to the cleaning apparatus 1 of the embodiment of the present invention, the user can select a suitable operation state according to actual situations (i.e., whether to use a handheld operation state or an upright operation state according to the specific situations), and when selecting an upright operation state, can also select a suction source according to the actual situations (i.e., whether to use the first suction device 112 as a suction source, the second suction device 122 as a suction source, or the first suction device 112 and the second suction device 122 simultaneously as a suction source), thereby improving the adaptability of the cleaning apparatus 1 to different use requirements.

In some embodiments of the invention, the cleaning device 1 may be provided with at least one of a first handheld usage mode, a second handheld usage mode, a third handheld usage mode, a fourth handheld usage mode in a handheld operational state.

In a first handheld use mode, as shown in fig. 2, the first suction device 112 operates to draw the handset assembly 11 in an airflow directly from the environment and deliver it to the dirt cup assembly 111 for removal of dirt. Thus, the user can simply and effectively perform a cleaning operation by holding or carrying the hand-held unit 11. Here, it will be appreciated that the difference between hand-held and hand-held is that when the user holds the handset assembly 11, the wrist is hand-held (as shown in fig. 8 where hand-holding is required for placement of the handset assembly 11), and when the user holds the handset assembly 11, the wrist is hand-held with an extension in a horizontal or oblique direction (as shown in fig. 6 where hand-holding is required for placement of the handset assembly 11).

In a second hand-held mode of use, as shown in fig. 6, the cleaning apparatus 1 further comprises an accessory suction head 131 (e.g. a brush head, a flat nozzle tube, an accessory floor brush, etc.), the accessory suction head 131 being mounted on the handset assembly 11, the first suction means 112 being operative to draw in an air stream from the accessory suction head 131 and deliver it to the dirt cup assembly 111 for removal of dirt. Thus, the user can simply and effectively perform a cleaning operation by holding or carrying the hand-held unit 11. In this mode of use, the accessory suction head 131 draws in airflow directly from the environment.

In a third mode of handheld use, as shown in fig. 7, the cleaning appliance 1 further comprises an accessory wand 132, the accessory wand 132 being mounted on the handset assembly 11, the first suction device 112 being operative to cause the accessory wand 132 to draw in an airflow and deliver it to the dirt cup assembly 111 for removal of dirt. Thus, a user can push the accessory wand 132 to move for cleaning operations by holding or otherwise carrying the handset assembly 11. In this use mode, the accessory wand 132 can directly draw in air from the environment, and the suction end of the accessory wand 132 can also be provided with an accessory suction head 131 or the like, so that the accessory wand 132 draws in air from the environment through the accessory suction head 131.

In a fourth mode of handheld use, as shown in fig. 8, the cleaning device 1 further comprises an accessory hose 133, the accessory hose 133 being mounted on the handset assembly 11, the first suction means 112 being operative to cause the accessory hose 133 to draw in an airflow and deliver it to the dirt cup assembly 111 for removal of dirt. Thus, a user may carry on a cleaning operation by holding the hand with one hand or the hand-held handset assembly 11, and holding the accessory hose 133 with the other hand. In this mode of use, the accessory hose 133 can draw in airflow directly from the environment, and the suction end of the accessory hose 133 can also be provided with an accessory wand 132 and/or accessory tip 131 or the like (as shown in figures 9 and 10) to draw in airflow from the environment through the accessory wand 132 and/or the accessory tip 131.

Of course, the invention is not limited thereto, and the cleaning device 1 may also be provided with more hand-held modes of use in a hand-held operating state, which will not be described in detail here.

In some embodiments of the invention, the power of the first suction means 112 may be less than the power of the second suction means 122, at which time the cleaning device 1 may be provided with a high power mode of operation in which the second suction means 122 is operated and the first suction means 112 is deactivated in the upright operating condition. That is, in the high power operation mode, the second suction device 122 having a larger power may be used as a suction source for suction, so that the cleaning performance of the upright operation state may be improved, while in the hand-held operation state, portability of the hand-held operation state is improved due to the smaller power of the first suction device 112 provided to the hand-held unit 11. In short, according to the cleaning apparatus 1 of the embodiment of the present invention, portability in the hand-held operation state and high performance in the upright operation state can be compatible.

In some embodiments of the present invention, each of the first suction device 112 and the second suction device 122 may include a motor and a fan, and when the motor drives the fan to rotate, the corresponding suction device may make a negative pressure to suck the airflow, wherein the motor included in the first suction device 112 may be a direct current motor or an alternating current motor (AC for short), and the motor included in the second suction device 122 may also be a direct current motor or an alternating current motor. The dc motor may include a brush dc motor (abbreviated as BDC) or a brushless dc motor (abbreviated as BLDC). In the following, several alternative embodiments will be given, but the invention is not limited to the following several embodiments.

Example 1

The first pumping device 112 may include a motor that is BDC or BLDC, and the second pumping device 122 may include a motor that is BLDC, and in this case, the handset assembly 11 may include a first power supply 113 (e.g., a normal battery and/or a rechargeable battery, etc.) that may provide direct current, and the upright machine assembly 12 may include a second power supply 123 (e.g., a normal battery and/or a rechargeable battery, etc.) that may provide direct current. Thus, when the first power supply 113 supplies power to the BDC or BLDC in the first suction device 112, the first suction device 112 may make a negative pressure induced air flow suction, and when the second power supply 123 supplies power to the BLDC in the second suction device 122, the second suction device 122 may make a negative pressure induced air flow suction.

At this time, in the upright operating state, the cleaning apparatus 1 may be provided with a plurality of operation modes, for example, one operation mode may be: the first suction device 112 is stopped, and the first power supply device 113 and the second power supply device 123 are used for simultaneously supplying power to the second suction device 122, so that the second suction device 122 serves as a suction source; for another example, another mode of operation may be: the first suction device 112 is shut down, and the second power supply device 123 is used to supply power to the second suction device 122 alone, so that the second suction device 122 serves as a suction source (in addition, if the first power supply device 113 is a rechargeable battery, the first power supply device 113 may also be charged by the second power supply device 123); for another example, another mode of operation may be: the second suction device 122 is shut down, the first suction device 112 is powered solely by the first power supply device 113, the first suction device 112 is made to act as a suction source, and so on.

It should be noted that, the positions where the first power supply device 113 and the second power supply device 123 are disposed are not limited, for example, in the specific example shown in fig. 1, the first power supply device 113 may be disposed on a side of the handset assembly 11 near the upright machine assembly 12, and the second power supply device 123 may be disposed on a lower portion of the push rod 1211, so that the center of gravity of the cleaning apparatus 1 in the handheld operation state and the upright operation state, respectively, may be effectively adjusted, so that the user may operate more lightly.

Example two

The first suction device 112 includes a dc motor (i.e., the motor included in the first suction device 112 is BDC or BLDC), the second suction device 122 includes an AC motor (i.e., the motor included in the second suction device 122 is AC), and the handset assembly 11 may include a first power supply 113 (e.g., a conventional battery and/or rechargeable battery, etc.) electrically connected to the first suction device 112, such that the first power supply 113 may be used to provide dc power to the first suction device 112 to drive the first suction device 112 to create a negative pressure to draw in an airflow, and the upright assembly 12 includes a second power connection structure (e.g., a power cord or power cord interface) electrically connected to the second suction device 122, the second power connection structure being adapted to be connected to an AC power source to provide AC power to the second suction device 122 to drive the second suction device 122 to create a negative pressure to draw in an airflow.

Therefore, since the power of the ac motor is generally higher than that of the dc motor, when the motor included in the second suction device 122 is the ac motor, the power of the second suction device 122 can be simply and effectively ensured to be higher than that of the first suction device 112, high cleaning effect of the vertical operation state is ensured, and since the cost of the ac motor is generally lower than that of the dc motor, the production cost of the vertical machine assembly 12 can be reduced. In addition, the volume of the dc motor is generally smaller than that of the ac motor, so that portability of the handset assembly 11 can be improved. In addition, when the first suction device 112 adopts a brushless dc motor, the cleaning effect of the handset assembly 11 can be improved due to the high operation energy efficiency of the brushless dc motor.

In a specific example of the second embodiment, the first power supply device 113 may include a rechargeable battery, and the rechargeable battery may be electrically connected to the second electrical connection structure when the handset assembly 11 is mounted on the upright assembly 12 (for example, the handset assembly 11 has a first electrical connection terminal thereon, the upright assembly 12 has a second electrical connection terminal thereon, and the first electrical connection terminal contacts with and forms an electrical connection with the second electrical connection terminal when the handset assembly 11 is mounted on the upright assembly 12, and the rechargeable battery is electrically connected to the second electrical connection structure through the electrical connection between the first electrical connection terminal and the second electrical connection terminal), at which time, the rechargeable battery may obtain charging when the second electrical connection structure is connected to the ac power source. Thus, the charging of the rechargeable battery in the handset assembly 11 can be performed simply and efficiently using the upright machine assembly 12 as a charging stand for the handset assembly 11.

Of course, the present invention is not limited thereto, for example, in other embodiments of the present invention, when the first power supply device 113 includes a rechargeable battery, the handset assembly 11 may further include a first power receiving structure electrically connected to the rechargeable battery, and when the first power receiving structure is connected to the ac power source, the rechargeable battery is also charged, so that the user can flexibly perform charging. Furthermore, it should be understood that in other embodiments of the present invention, the first power receiving structure and the second power receiving structure may coexist, that is, when the first power supply device 113 includes a rechargeable battery, the stand assembly 12 may further include the second power receiving structure while the handset assembly 11 includes the first power receiving structure, and only a corresponding circuit is required to control the charging logic of the rechargeable battery.

When the first power supply device 113 includes a rechargeable battery and the rechargeable battery can be charged by the second power receiving structure, the cleaning apparatus 1 may be provided with: a first upright use mode (or upright charge mode) in which the second powered structure is connected to an ac power source, the second pumping device 122 is operated, the first power supply 113 is charged and the first pumping device 112 is deactivated. The cleaning device 1 may further include: a second upright mode of use (or upright cordless mode) in which the second electrical connection is disconnected from the power source, the second suction device 122 is deactivated, and the first power supply 113 drives the first suction device 112. It will be appreciated that the first upright mode of use is a further refinement of the high power mode of operation when the power of the first suction device 112 is less than the power of the second suction device 122.

Therefore, in the second vertical use mode, the first suction device 112 is driven to suck dust by using the stored electric quantity in the rechargeable battery, so that the second power connection structure is not required to be connected with a power supply, adverse effects on cleaning operation due to the use of a power line are avoided, and the operation convenience is improved. In the first upright use mode, the second suction device 122 can be used for sucking dust, and the rechargeable battery in the first power supply device 113 can be charged, so that the user does not need to independently draw out time to charge the first power supply device 113, and two purposes are achieved. Also, when the power of the first suction means 112 is smaller than the power of the second suction means 122, if the cleaning apparatus 1 is switched to the first upright use mode, since the cleaning apparatus 1 adopts the second suction means 122 having a larger power as the suction source in this mode, the cleaning effect can be improved better.

In order to achieve the above-described switching of the first upright use mode and the second upright use mode, the cleaning apparatus 1 according to the embodiment of the present invention may further include an air duct switching valve 3, and the air duct switching valve 3 may include: the valve body 31, the valve 32 and the rotating shaft 33 are arranged in the valve body 31, the air inlet channel 311, the first air channel 312 and the second air channel 313 are arranged in the valve body 31, the inlet of the first air channel 312 and the inlet of the second air channel 313 are both communicated to the air inlet channel 311, therefore, when the inlet of the first air channel 312 is opened, the air flow in the air inlet channel 311 can enter the first air channel 312 through the inlet of the first air channel 312, and when the inlet of the second air channel 313 is opened, the air flow in the air inlet channel 311 can enter the second air channel 313 through the inlet of the second air channel 313.

It should be noted that, the inlet of the air inlet channel 311, the outlet of the first air duct 312, and the outlet of the second air duct 313 are all in communication with the atmosphere outside the cleaning apparatus 1. As shown in fig. 3 and 4, the inlet of the air inlet channel 311 is communicated to the dust cup assembly 111, and the dirty air inlet of the dust cup assembly 111 may be communicated with the external atmosphere, so that the inlet of the air inlet channel 311 is communicated to the external atmosphere; the outlet of the first air duct 312 is connected to the first suction device 112, and the first suction device 112 can be connected to the external atmosphere through the first exhaust outlet 110, so that the outlet of the first air duct 312 is connected to the external atmosphere; the outlet of the second air duct 313 is connected to the second suction device 122, and the second suction device 122 may be connected to the external atmosphere through the second exhaust outlet 120, so that the outlet of the second air duct 313 is connected to the external atmosphere.

As shown in fig. 11, a valve 32 is provided in the valve body 31 at the inlet of the first air duct 312 and the inlet of the second air duct 313, and a rotation shaft 33 is provided between the valve 32 and the valve body 31 to make the valve 32 rotatable with respect to the valve body 31, wherein the air duct switching valve 3 is configured as follows.

When the air pressure in the first air duct 312 is less than the air pressure in the second air duct 313 (e.g., when the first suction device 112 is activated to create a negative pressure in the first air duct 312 and the second suction device 122 is deactivated to maintain the second air duct 313 at atmospheric pressure as shown in fig. 5), the valve 32 is rotated toward a first position (e.g., the position shown in fig. 13, 16, 18, 20, 22) that opens the inlet of the first air duct 312 and closes the inlet of the second air duct 313.

When the air pressure in the second air duct 313 is less than the air pressure in the first air duct 312 (e.g., as shown in fig. 3 and 4, when the second suction device 122 is activated to create a negative pressure in the second air duct 313 and the first suction device 112 is deactivated to maintain the atmospheric pressure in the first air duct 312), the valve 32 is rotated toward a second position (e.g., the position shown in fig. 15, 17, 19, 21, 23) in which the inlet of the second air duct 313 is opened and the inlet of the first air duct 312 is closed.

Thus, by providing the above-described duct switching valve 3, the direction of the air flow of the cleaning apparatus 1 in the first upright use mode and the second upright use mode can be understood, which will be described in detail later.

In some embodiments of the present invention, as shown in fig. 1, the second suction device 122 may be provided at the junction of the pushrod 1211 and the ground brush 1212. Thus, the center of gravity of the vertical machine assembly 12 can be adjusted, so that a user can push the vertical machine assembly 12 to run on a running surface more effort-saving, and the problem of dumping of the vertical machine assembly 12 can be improved. Moreover, by arranging the second suction device 122 at the connection part of the push rod 1211 and the ground brush 1212, the ground brush 1212 can be better contacted with the ground, the dust collection opening can be better attached to the surface to be cleaned, and the dust collection effect of the ground brush 1212 is improved. In addition, the specific installation manner of the second suction device 122 is not limited, and for example, the second suction device may be installed on the push rod 1211 or the ground brush 1212, as long as the second suction device is located at the connection portion between the push rod 1211 and the ground brush 1212.

Further, as shown in fig. 4, a second air outlet 120 may be provided at the second suction device 122, and the air flow sucked through the second suction device 122 may be discharged to the outside environment through the second air outlet 120, so that when the outlet of the second air duct 313 communicates with the second suction device 122, the outlet of the second air duct 313 may communicate with the atmosphere outside the cleaning apparatus 1. The way in which the outlet of the second air duct 313 communicates with the second suction device 122 is not limited, for example, in some embodiments of the present invention, the push rod 1211 has a communication port 1211b, the push rod 1211 has an exhaust channel 1211a therein, one end of the exhaust channel 1211a communicates with the communication port 1211b, and the other end of the exhaust channel 1211a communicates with the second suction device 122, so that when the handset assembly 11 is mounted on the upright machine assembly 12, the outlet of the second air duct 313 interfaces with the communication port 1211 b. Thereby, the air flow discharged from the second air duct 313 may enter the exhaust duct 1211a through the communication port 1211b, flow to the second suction device 122 along the exhaust duct 1211a, and then be discharged from the second air outlet 120.

As shown in fig. 1, the first suction device 112 may be located above the dirt cup assembly 111 when the handset assembly 11 is mounted on the upright assembly 12. Therefore, in the vertical operation state, the distance between the dust cup assembly 111 and the ground brush 1212 can be shortened, so that dust-containing airflow sucked by the ground brush 1212 can be more quickly and effectively fed into the dust cup assembly 111, the air flow loss and the air flow leakage are reduced, and the cleaning effect of the vertical operation state is improved.

Further, as shown in fig. 5, a first air outlet 110 may be provided at the first suction device 112, and the air flow sucked through the first suction device 112 may be discharged to the outside environment through the first air outlet 110, so that when the outlet of the first air duct 312 communicates with the first suction device 112, the outlet of the first air duct 312 may communicate with the atmosphere outside the cleaning apparatus 1. Thus, the air flow discharged from the first air duct 312 may flow to the first suction device 112 and then be discharged from the first air outlet 110. In addition, the connection manner between the dust cup assembly 111 and the floor brush 1212 is not limited, for example, in the example shown in fig. 3, the upright machine assembly 12 may have a base 124 provided on the push rod 1211, the second power supply device 123 may be provided on the base 124, and the base 124 defines a gas supply channel 1241 therein, the base 124 has a gas supply port 1242, one end of the gas supply channel 1241 is communicated with the gas supply port 1242, and the other end is communicated with the dust suction port 12120 of the floor brush 1212 through the adapter 125 or the like.

When the handset assembly 11 is mounted on the upright assembly 12, the base 124 is supported at the bottom of the handset assembly 11 and the dirty air inlet of the dirt cup assembly 111 communicates with the air supply port 1242 so that when at least one of the first suction device 112 and the second suction device 122 is in operation, a dust laden air stream drawn in from the suction port 12120 of the floor brush 1212 may enter the air supply passage 1241 through the adapter 125 and then flow into the dirt cup assembly 111 through the air supply port 1242. In addition, the dirt cup assembly 111 may have a suction tube segment 1110 thereon, the outlet of the suction tube segment 1110 being in communication with the dirty air inlet of the dirt cup assembly 111, and the suction tube segment 1110 being inserted into the base 124 when the handset assembly 11 is mounted on the upright assembly 12 such that the inlet of the suction tube segment 1110 is in aligned communication with the air supply port 1242, whereby the air supply port 1242 may be in communication with the dirty air inlet of the dirt cup assembly 111 via the suction tube segment 1110.

As shown in fig. 1, the dirt cup assembly 111 may include: the cup housing and the cyclone (not shown), which may be a primary cyclone or a multi-stage cyclone, disposed within the cup housing may extend vertically along a line and the longitudinal axis L1 of the dirt cup assembly 111 (i.e., the axis of the cyclone or the axis about which the airflow rotates during cyclone) may extend laterally when the handset assembly 11 is mounted to the upright assembly 12. Therefore, in the vertical operating state, the longitudinal axis of the dust cup assembly 111 extends vertically, so that the cleaning effect of the dust cup assembly 111 can be improved, and the longitudinal axis of the first suction device 112 extends transversely, so that the center of gravity of the whole machine of the cleaning equipment 1 can be lowered, the cleaning equipment 1 can run more stably and is not easy to topple over, and a user can operate more in a labor-saving manner.

It will be appreciated that when the dirt cup assembly 111 comprises a cup housing and a cyclone separator disposed within the cup housing, the bottom of the cup housing is a dust collection chamber, air flow entering the cup housing may be cyclone separated by the cyclone separator, and when the longitudinal axis of the dirt cup assembly 111 extends vertically, separated dirt may be reliably and effectively deposited within the dust collection chamber at the bottom of the cup housing under the action of gravity, and the separated air flow may effectively flow out of the cup housing, thereby improving the dirt-air separation effect of the dirt cup assembly 111 and effectively solving the problem of the air flow rolling up the separated dirt.

In the following, with reference to fig. 3-5, the flow direction of the cleaning device 1 in a first upright mode of use and in a second upright mode of use will be briefly described.

As shown in fig. 3 and 4, in the first upright use mode, the second suction device 122 is operated, the first suction device 112 is stopped, and at this time, the air duct switching valve 3 is automatically switched to: the air inlet channel 311 is communicated with the second air channel 313 and is blocked from the first air channel 312, at this time, as shown by the solid arrow trend in fig. 3, the dust-containing air flow sucked from the ground brush 1212 may first enter the dust cup assembly 111 for cyclone separation, the separated dust is deposited in the dust cup assembly 111, the separated air flow enters the air inlet channel 311, then enters the push rod 1211 through the second air channel 313, then as shown by the solid arrow trend in fig. 4, the air flow entering the push rod 1211 flows to the second suction device 122, and then is discharged to the environment from the second air outlet 120 at the second suction device 122.

As shown in fig. 5, in the second vertical use mode, the second suction device 122 is stopped, and the first suction device 112 is operated, at this time, the air duct switching valve 3 is automatically switched to: the air inlet channel 311 is communicated with the first air channel 312 and is blocked from the second air channel 313, at this time, as shown by the solid arrow trend in fig. 5, the dust-containing air flow sucked from the ground brush 1212 can enter the dust cup assembly 111 for cyclone separation, the separated dust is deposited in the dust cup assembly 111, the separated air flow enters the air inlet channel 311, then flows to the first suction device 112 through the first air channel 312, and is discharged to the environment from the first air outlet 110 at the first suction device 112.

Of course, the present invention is not limited thereto, and the cleaning apparatus may further have a plurality of upright use modes in the upright operation state, for example, may further include a third upright use mode in which the second power receiving structure is connected to the ac power source, the second suction device 122 is operated, the first power supply device 113 charges and drives the first suction device 112 to operate, that is, in the third upright use mode, both the first suction device 112 and the second suction device 122 are used as suction sources to perform dust suction operation, thereby further improving the operation effect of the whole machine. Further, it should be noted that when the first suction device 112 and the second suction device 122 are simultaneously operated, the cleaning apparatus 1 may not include the above-described air duct switching valve 3.

Hereinafter, a cleaning apparatus 1 according to a specific embodiment of the present invention is described with reference to fig. 1 to 5.

The cleaning apparatus 1 includes: a handset assembly 11 and a stand assembly 12, wherein the handset assembly 11 comprises a dirt cup assembly 111 and a first suction device 112, the first suction device 112 comprising a direct current motor, the handset assembly 11 comprising a first power supply 113 electrically connected to the first suction device 112, the first power supply 113 comprising a rechargeable battery; the vertical machine assembly 12 includes a machine body component 121 and a second suction device 122, the second suction device 122 including an ac motor, the vertical machine assembly 12 including a second electrical connection electrically connected to the second suction device 122, the second suction device 122 having a power greater than the power of the first suction device 112. The handset assembly 11 is detachably connected to the upright assembly 12, and the rechargeable battery in the first power supply 113 is electrically connected to the second power receiving structure when the handset assembly 11 is mounted on the upright assembly 12.

The cleaning apparatus 1 has a hand-held operating condition in which the handset assembly 11 is detached from the upright assembly 12, and an upright operating condition in which the first suction device 112 operates to draw in an airflow from the dirt cup assembly 111 and remove dirt; in the upright operating state, the handset assembly 11 is mounted on the upright assembly 12. Specifically, the upright operating state may include: a first vertical use mode in which the second power connection structure is connected to the ac power source, the second suction device 122 is operated, the first power supply device 113 is charged, and the first suction device 112 is stopped; in the second upright mode of use, the second electrical connection is disconnected from the power source, the second pumping device 122 is deactivated, and the first power supply 113 drives the first pumping device 112.

Briefly, in accordance with the cleaning apparatus 1 of the present embodiment, a relatively low power DC motor is installed in the handset assembly 11 as a suction source in the hand-held operating mode and a suction source in the second upright mode of use, while a relatively high power AC motor is installed in the upright assembly 12 as a suction source in the first upright mode of use.

Therefore, when the cleaning device 1 is switched to the first vertical use mode, the alternating current motor with higher power is adopted as a suction source of the whole machine, and the air flow with dust sucked from the ground brush 1212 directly enters the dust cup assembly 111 to perform purification treatment on the air, so that the whole machine can show higher suction force and work suction, and stronger vertical cleaning capability is provided. When the handset assembly 11 is separated from the upright handset assembly 12, the handset assembly 11 can be used as an independent handset, and the power of the direct current motor carried by the handset assembly 11 used alone is smaller, so that the handset assembly 11 is lighter, is beneficial to handheld or portable operation, and has better use experience.

Next, referring to fig. 11 to 23, the duct switching valve 3 according to some embodiments of the present invention is described.

The duct switching valve 3 according to the embodiment of the present invention may have the following advantages: the switching effect of the air duct switching valve 3 in the first embodiment of the invention does not need manual operation of a user, so that the problem of incomplete switching caused by manual mechanical external force operation is avoided, the problem of switching air leakage is avoided, and the switching reliability is high; the air duct switching valve 3 of the second embodiment of the invention can be arranged in the cleaning equipment entirely, and parts (such as a knob, a button or a push rod, etc.) which are exposed outside the cleaning equipment and used for mechanical contact by a user are not present, so that the air duct switching valve 3 is not in mechanical contact with the outside, the possibility of damage of the air duct switching valve 3 by external force is avoided, and the service life is long; the air duct switching valve 3 of the third and the fundamental embodiments of the present invention does not need to use a complicated mechanical mechanism, does not need to use an electronic element with high cost, can automatically perform adaptive switching along with the change of the pressure difference between the first air duct 312 and the second air duct 313, has a very simple structure, fewer parts, smaller volume, lower cost, high reliability, and is suitable for wide popularization and application.

In some embodiments of the present invention, as shown in fig. 11, the inlet of the first air duct 312 and the inlet of the second air duct 313 meet at a junction, the rotating shaft 33 is disposed at the junction 314 (i.e., the junction of the inlet of the first air duct 312 and the inlet of the second air duct 313), the valve 32 includes a first valve portion 321 and a second valve portion 322 distributed on both sides of the rotating shaft 33, the first valve portion 321 is used for opening and closing the inlet of the first air duct 312, and the second valve portion 322 is used for opening and closing the inlet of the second air duct 313. Therefore, the air duct switching valve 3 according to the embodiment of the invention has a simple structure, and can simply and effectively realize the air duct switching action under the pressure difference effect of the first air duct 312 and the second air duct 313. Of course, the invention is not limited thereto and the valve 32 may be provided in a more complex configuration.

In some embodiments of the present invention, as shown in fig. 11, the duct switch valve 3 may include at least one of a first sealing stopper 34 and a second sealing stopper 35, wherein the first sealing stopper 34 is disposed around the inlet of the first duct 312, and the first valve portion 321 is located within the first duct 312 and rotates on a side of the first sealing stopper 34 away from the air intake duct 311 (i.e., a portion of the valve 32 located in the first duct 312, which is located to rotate between the first suction source and the first sealing stopper 34), as shown in fig. 15, when the valve 32 rotates to the second position, the first valve portion 321 is stopped against the first sealing stopper 34 to close the inlet of the first duct 312.

As shown in fig. 11, the second sealing stopper 35 is disposed around the inlet of the second air duct 313, the second valve portion 322 is located in the second air duct 313 and rotates on a side of the second sealing stopper 35 away from the air inlet channel 311 (i.e., a portion of the valve 32 located in the second air duct 313, which is located between the second suction source and the second sealing stopper 35, rotates), and as shown in fig. 13, the second valve portion 322 is stopped against the second sealing stopper 35 to close the inlet of the second air duct 313 when the valve 32 rotates to the first position.

Thus, by providing the first seal stopper 34, the reliability of stopping the valve 32 at the second position can be improved, and the sealing property of closing the first duct 312 can be improved, and by providing the second seal stopper 35, the reliability of stopping the valve 32 at the first position can be improved, and the sealing property of closing the second duct 313 can be improved. Here, it should be noted that, according to the embodiment of the present invention, the first sealing abutment 34 and the second sealing abutment 35 may be integrally formed on the valve body 31, or may be fixed on the valve body 31 by a subsequent assembly process (such as welding, bonding, snap connection, and threaded connection), which is not limited herein.

The duct switching valve 3 may not include the first seal stopper 34, and may stop the valve 32 at the first position by engaging the first valve portion 321 with the inner wall of the first duct 312, or stop the valve 32 at the second position by engaging the second valve portion 322 with the inner wall of the second duct 313. Further, the sealing effect when closing the corresponding duct can be improved by providing sealing rings or the like on the first valve portion 321 and the second valve portion 322.

As shown in fig. 11, at least one of the first valve part 321 and the second valve part 322 may be a flat valve sheet 320, wherein "flat valve sheet 320" means: the thickness of the plate-shaped sheet body, the thickness of the plate valve plate 320 is thinner, the cost is lower, the moment for driving the valve 32 to rotate is smaller, thereby improving the reliability of the action of the valve 32 and improving the effectiveness of the switching action of the air duct, that is, when one of the first suction source and the second suction source is just started, although the pressure difference between the first air duct 312 and the second air duct 313 is smaller, the valve 32 can also smoothly rotate, and the timeliness and the reliability of the switching action of the air duct switching valve 3 are improved. Of course, the present invention is not limited thereto, and in other embodiments of the present invention, the first valve part 321 and the second valve part 322 may be respectively configured in other shapes, such as a curved plate shape, a sphere shape, and the like.

Specifically, the connection between the plate valve 320 and the shaft 33 is not limited. For example, the plate valve 320 and the rotation shaft 33 may be directly connected (the first valve portion 321 is the plate valve 320 and is directly connected to the rotation shaft 33 as shown in fig. 11), thereby facilitating the processing. For another example, the plate valve 320 may be indirectly connected to the rotating shaft 33, for example, in the example shown in fig. 11, the plate valve 320 may be connected to the rotating shaft 33 by a return member 36 (the second valve portion 322 shown in fig. 11 is the plate valve 320 and is connected to the rotating shaft 33 by the return member 36), the return member 36 includes a first segment 361 and a second segment 362, the first segment 361 is perpendicular to the second segment 362 (i.e. the section of the return member 36 is "L" -shaped), an end of the first segment 361 away from the second segment 362 is connected to the rotating shaft 33, and an end of the second segment 362 away from the first segment 361 is connected to an end of the plate valve 320 near the rotating shaft 33, and the first segment 361 is parallel to the plate valve 320.

Thereby, the connection reliability of the flat valve sheet 320 and the rotation shaft 33, that is, the structural strength of the root portion of the corresponding valve portion can be improved, thereby improving the root portion fracture resistance of the corresponding valve portion. Optionally, the shaft 33, the valve 32, the folded piece 36 and the like may be integrally formed parts, or may be separate parts which are subsequently assembled, and when integrally formed parts, the valve is convenient to process and has good structural strength.

Next, the operation principle of the duct switching valve 3 according to one embodiment of the present invention will be briefly described with reference to fig. 11 to 15.

As shown in fig. 11, the air pressure of the first air duct 312 is controlled by a first suction source (a first suction device described later), the air pressure of the second air duct 313 is controlled by a second suction source (a second suction device described later), and when both the first suction source and the second suction source are not operated, the air pressure is in the first air duct 312 and the second air duct 313, and the valve 32 is in a free state.

As shown in fig. 12, when the first suction source is started and the second suction source is stopped, the air flow direction in the valve body 31 is shown by the solid arrow in fig. 12, the valve 32 is pushed by the air flow to rotate in the counterclockwise direction shown by the hollow arrow in the drawing, and at this time, the air flow of the first air duct 312 is the sum of the air flow of the second air duct 313 and the air flow of the air intake duct 311.

As shown in fig. 13, when the valve 32 rotates to the first position shown in fig. 13, the first valve portion 321 abuts against the inner wall of the first air duct 312 and/or the second valve portion 322 abuts against the second sealing abutment 35, the first air duct 312 is fully opened, and the second air duct 313 is fully closed, and at this time, the air flow of the first air duct 312 is fully provided by the air inlet channel 311. Because the first air duct 312 is negative pressure, the second air duct 313 is in communication with the outside atmosphere at normal pressure, so that the second valve portion 322 can be tightly and reliably stopped against the second sealing stop member 35 under the pressure difference between the first air duct 312 and the second air duct 313, and the greater the pressure difference, i.e. the greater the suction force of the first suction source, the greater the pressure F2 applied to the second valve portion 322, the better the closing sealing effect of the second air duct 313.

As shown in fig. 14, when the first suction source is stopped and the second suction source is started, the first air duct 312 returns to be in communication with the outside atmosphere to be at an atmospheric pressure, the second air duct 313 is at a negative pressure under the suction action of the second suction source, the valve 32 rotates clockwise as shown by the hollow arrow in fig. 14 under the pressure difference action of the first air duct 312 and the second air duct 313, and when the second valve portion 322 is not closing the second air duct 313, the air flow of the second air duct 313 is the sum of the air flow of the first air duct 312 and the air flow of the air intake channel 311 as shown by the solid arrow in fig. 14.

As shown in fig. 15, when the valve 32 rotates to the second position shown in fig. 15, the second valve portion 322 abuts against the inner wall of the second air duct 313 and/or the first valve portion 321 abuts against the first sealing abutment 34, the second air duct 313 is fully opened, and the first air duct 312 is fully closed, and at this time, the air flow of the second air duct 313 is fully provided by the air inlet channel 311. Since the second air duct 313 is negative pressure, the first air duct 312 is in communication with the outside atmosphere at normal pressure, so that the first valve portion 321 can be tightly and reliably stopped against the first sealing stopper 34 under the pressure difference between the first air duct 312 and the second air duct 313, and the greater the pressure difference, that is, the greater the suction force of the second suction source, the greater the pressure F1 applied to the first valve portion 321, and the better the closing sealing effect of the first air duct 312.

It can be seen that, regardless of the starting sequence of the first suction source and the second suction source, the valve 32 can be automatically, accurately and reliably switched to the correct position under the pressure difference between the first air duct 312 and the second air duct 313 whenever the suction source is switched.

In addition, it will be appreciated that, in order to ensure the reliability of the closing effect of the first air duct 312 and the second air duct 313, the respective portions of the first sealing stopper 34, the second sealing stopper 35, the first air duct 312, and the second air duct 313 may be configured to have a structural shape matching the respective positions of the valve 32, so that when the valve 32 reaches the first position, as shown in fig. 13, the first valve portion 321 may fit the inner wall of the first air duct 312 seamlessly, the second valve portion 322 may fit the second sealing stopper 35 seamlessly, and when the valve 32 reaches the second position, as shown in fig. 15, the second valve portion 322 may fit the inner wall of the second air duct 313 seamlessly, and the first valve portion 321 may fit the first sealing stopper 34 seamlessly.

In some embodiments of the present invention, the inlet duct section of the first duct 312 extends along the first linear direction L1, the inlet duct section of the second duct 313 extends along the second linear direction L2, and the angle a between the first linear direction L1 and the second linear direction L2 is as follows: 0.ltoreq.a.ltoreq.180°, that is, the inlet duct section of the first duct 312 and the inlet duct section of the second duct 313 may be disposed in parallel (i.e., a=0°, as shown in fig. 22 to 23), or vertically (i.e., a=90°, as shown in fig. 11 to 17), or at an acute or obtuse angle (i.e., 90 ° < a < 180 °, as shown in fig. 18 to 19), or side by side (i.e., a=180°, as shown in fig. 20 to 21). Therefore, the air duct switching valve 3 can be suitable for cleaning equipment with different structural forms, that is, the air duct switching valve 3 with corresponding shape can be designed according to the specific structure and the position of the air duct switching valve 3 required by the cleaning equipment, so that different practical requirements are met, and the adaptability of the air duct switching valve 3 according to the embodiment of the invention is improved.

In addition, it is understood that, in conjunction with the above description of the operation principle of the air duct switching valve 3 shown in fig. 11 to 15, referring to the air flow direction shown by the solid arrows in fig. 16 to 23, those skilled in the art can understand the operation principle of the air duct switching valve 3 shown in fig. 16 to 23, which is not repeated herein.

As shown in fig. 11 to 17, when the above included angle a satisfies: when a=90°, that is, when the inlet duct section of the first duct 312 and the inlet duct section of the second duct 313 are disposed vertically, if the first valve portion 321 and the second valve portion 322 are both the flat plate valve sheets 320, the first valve portion 321 and the second valve portion 322 may be disposed in parallel (that is, the central plane of the first valve portion 321 is parallel to the central plane of the second valve portion 322, as shown in fig. 11), or may be disposed in a coplanar manner (that is, the central plane of the first valve portion 321 is coplanar with the central plane of the second valve portion 322, as shown in fig. 16 to 17). Thus, the structure of the valve 32 can be simplified, and the duct switching operation can be realized simply, effectively, and reliably. In summary, when the shapes and the relative positions of the first air duct 312 and the second air duct 313 are changed, only the shape and the setting position of the valve 32 are required to be adjusted to achieve the air duct switching effect in the embodiment of the present invention, which is not described herein.
