Detailed Description

In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the application provides a surface cleaning system, which aims to solve the problem that in the prior art, in some application scenes (such as outdoor or windows far away from sockets) an external power supply cannot be provided for a surface cleaning device, so that the surface cleaning device cannot be used.

Referring to fig. 1, a schematic structural diagram of a surface cleaning system according to an embodiment of the present disclosure is shown. As shown in fig. 1, the surface cleaning system includes a surface cleaning apparatus 100, a power connector 200, and a mobile power supply 300. Wherein the mobile power source 300 is electrically connected to the power connector 200 via the first power line 411, the power connector 200 is electrically connected to the surface cleaning apparatus 100 via the second power line 412, and when the surface cleaning apparatus 100 is in operation, the surface cleaning apparatus 100 can be powered by the mobile power source 300, and the power supply path is shown as a dashed line L1 in fig. 1. In addition, when the mobile power supply 300 is low in power, the mobile power supply 300 can be charged by connecting to a power grid (for example, 220V commercial power) through the power connector 200, and the charging path is shown as a dashed line L2 in fig. 1.

It can be appreciated that the mobile power source 300 is mobile (fixed in a particular position relative to the socket), so that the surface cleaning apparatus 100 is not limited by the work scenario, and the adaptability to the application scenario is improved. For example, the mobile power source 300 may also be moved outdoors to power the surface cleaning apparatus 100 when outdoors.

Generally, the mobile power source 300 needs to be provided with a charging connector and a power supply connector, wherein the charging connector is used for charging, and the power supply connector is used for discharging. However, the two connectors may result in a complicated structure of the portable power source 300. To solve this problem, embodiments of the present application provide a power connector, through which the charging and discharging functions of the mobile power supply 300 can be simultaneously achieved, and the following description is made in detail with reference to the accompanying drawings.

Referring to fig. 2, a schematic perspective view of a power connector 200 according to an embodiment of the present disclosure is shown; referring to fig. 3, an exploded view of a power connector 200 according to an embodiment of the present disclosure is shown. As shown in fig. 2 and fig. 3, the power connector 200 includes a connector housing 210, and 3 connecting terminals are provided on the connector housing 210 to form a Y-shaped power connector 200. For convenience of description, the 3 connection terminals are referred to as a first connection terminal 221, a second connection terminal 222, and a third connection terminal 223, respectively. The first connection end 221 is used for connecting the mobile power source 300, the second connection end 222 is used for connecting a load (for example, the surface cleaning apparatus 100), and the third connection end 223 is used for connecting a charging device (for example, an adapter). Specifically, the second connection end 222 is electrically connected to the first connection end 221, so that when the second connection end 222 is connected to a load, a current loop is formed between the mobile power supply 300 and the load, and the load can be supplied with power through the mobile power supply 300; the third connection terminal 223 is electrically connected to the first connection terminal 221, so that when the third connection terminal 223 is connected to a charging device, a current loop is formed between the charging device and the mobile power supply 300, and the mobile power supply 300 can be charged through the charging device. In addition, the first connection end 221 may be electrically connected to the mobile power supply 300 through a first power line 411; the second connection terminal 222 may be electrically connected to the load through a second power line 412.

To sum up, the power connector 200 provided in the embodiment of the present application can be compatible with a charging and discharging usage scenario, that is, the mobile power source 300 only needs to be connected to one power connector 200 to realize charging and discharging functions, so that the structure of the mobile power source 300 is simpler.

It can be understood that the first connection terminal 221 may always maintain a connection state with the mobile power supply 300. When power needs to be supplied to the load, the power is connected to the load through the second connection end 222, and the mobile power supply 300 supplies power to the load; when the mobile power supply 300 needs to be charged, the third connection terminal 223 is connected to a charging device to charge the mobile power supply 300. However, if the second connection terminal 222 and the third connection terminal 223 are simultaneously connected to the load and the charging device, respectively, the portable power source 300 or the load may be damaged. For example, the service life of the mobile power supply 300 is reduced, or the load is damaged.

In response to this problem, in a possible implementation, a shielding member 230 is further disposed on the joint housing 210, and the shielding member 230 is used for selectively shielding the second connection end 222 or the third connection end 223. For example, in a state shown in fig. 4 in which the second connection terminal 222 is shielded by the shield 230, the user can connect the charging device only through the third connection terminal 223; in the state shown in fig. 5, in which the shield 230 shields the third connection end 223, the user can connect the surface cleaning apparatus 100 only through the second connection end 222. Therefore, by the shield 230, it is possible to prevent a user from simultaneously connecting a load and a charging device to cause damage to the portable power source 300 or the load.

In a specific implementation, the shielding member 230 may be rotatably connected to the joint housing 210 through a rotating shaft 240, and the swing range of the shielding member 230 is limited between the second connection end 222 and the third connection end 223. That is, the shield 230 may swing between the second connection end 222 and the third connection end 223 to shield the second connection end 222 or the third connection end 223 such that the second connection end 222 and the third connection end 223 cannot be simultaneously exposed to the outside of the shield 230. Of course, the shielding member 230 may be connected to the joint housing 210 by other moving members (e.g., a snap, a hinge, a connecting rod, etc.) besides the rotating shaft 240, which is not particularly limited by the embodiment of the present application.

In one possible implementation, the outer surface of the shield 230 is provided in an arcuate configuration. The arc structure can prevent sharp corners from being present on the outer surface of the shielding member 230, and prevent the user from scratching the shielding member 230 when the user rotates the shielding member.

In one possible implementation, the shielding member 230 is made of a flexible material, i.e., the shielding member 230 has an elastic force. It can be understood that when the shielding member 230 is sleeved outside the second connection end 222 or the third connection end 223, the shielding member 230 is more tightly connected to the second connection end 222 or the third connection end 223 due to the elastic force of the shielding member 230, so as to prevent foreign objects such as dust or water from entering the second connection end 222 or the third connection end 223, thereby improving the reliability of the power connector 200. It should be noted that, when the shielding member 230 is made of a flexible material, the shielding member 230 may be fixedly connected to the connector housing 210, and the shielding member 230 swings between the second connection end 222 and the third connection end 223 by its own elastic force. Of course, the shielding member 230 may also be connected to the connector housing 210 via a movable member, which is not limited in this embodiment.

In one possible implementation, the shield 230 is a transparent material. With this arrangement, it is possible to facilitate the user's observation of the power connector 200. Specifically, since the shielding member 230 is made of a transparent material, even if the shielding member 230 shields the second connection end 222 or the third connection end 223, a user can still observe the state of the second connection end 222 or the third connection end 223 (for example, observe whether the second connection end 222 or the third connection end 223 has a fault, etc.), thereby improving convenience of use for the user.

Referring to fig. 4 and fig. 5, in the embodiment of the present application, the first connection end 221, the second connection end 222, and the third connection end 223 surround the connector housing 210 and are uniformly distributed on the connector housing 210, and the arrangement manner can avoid mutual interference between the connection ends, so that a user has more operation space, and the user can conveniently perform plugging and unplugging operations of the connector. For example, the second connection end 222 and the first and third connection ends 221 and 223 each have a larger space therebetween to facilitate a user connecting the surface cleaning apparatus 100 through the second connection end 222; the third connection terminal 223 and the first connection terminal 221 and the second connection terminal 222 have a large space therebetween, so that a user can conveniently connect the charging device through the third connection terminal 223.

It can be understood that the second connection terminal 222 and the third connection terminal 223 of the power connector 200 provided in the embodiment of the present application are respectively used for connecting different devices. Specifically, the second connection terminal 222 is used for connecting a load, and the third connection terminal 223 is used for connecting a charging device. If the user operates improperly when using the mobile power supply, the second connection terminal 222 and the third connection terminal 223 are connected in reverse (the charging device is connected through the second connection terminal 222 or the load is connected through the third connection terminal 223), which may cause damage to the mobile power supply 300 or the load. To this problem, this embodiment of this application sets up second link 222 and third link 223 as different interface types to avoid the user to connect second link 222 and third link 223 in reverse, and improve the convenience of user operation.

In a specific implementation, the second connection end 222 is a male connector, and the third connection end 223 is a female connector; alternatively, the second connection end 222 is a female connector and the third connection end 223 is a male connector. That is to say, second connection end 222 and third connection end 223 may be distinguished through a male-female connector, and of course, second connection end 222 and third connection end 223 may also be distinguished through other structures, which is not specifically limited in this embodiment of the present application.

The following is a description of a specific structure of the mobile power supply 300 according to the embodiment of the present application.

Referring to fig. 6, an exploded view of a mobile power supply 300 according to an embodiment of the present disclosure is shown. For convenience of illustration, a top portion and a bottom portion are defined on the mobile power supply 300. In some possible implementations, the "top" may also be referred to as "upper" and the "bottom" as "lower", which are not specifically limited by the embodiments of the present application.

As shown in fig. 6, the mobile power supply 300 includes a mobile power supply housing 310, a support member 320 is disposed inside the mobile power supply housing 310, and the support member 320 defines a first space and a second space inside the mobile power supply housing 310. The first space is a space between the support 320 and the top of the mobile power supply housing 310, and the second space is a space between the support 320 and the bottom of the mobile power supply housing 310.

An electric storage device 330 (e.g., a battery) is provided in the first space, and is located at an upper portion of the support member 320. It is understood that the electrical storage device 330 is used to store or release electrical energy, and the above-described charging or discharging is charging or discharging of the electrical storage device 330. Since the electrical storage device 330 is generally heavy, disposing the electrical storage device 330 on the upper portion of the support member 320 makes it possible to drag the electrical storage device 330 by the support member 320. After the stay 320 and the portable power supply case 310 are fixed, an interlayer is formed between the stay 320 and the portable power supply case 310, and the power storage device 330 can be sandwiched between the stay 320 and the portable power supply case 310, thereby preventing the power storage device 330 from shaking between the portable power supply cases 310. Meanwhile, the mobile power supply housing 310 is in contact with the power storage device 330 to dissipate heat of the power storage device 330.

Control board 350 is further provided above power storage device 330 (control board 350 is located in the first space), and control board 350 is provided with keys 351 and light guide 352. The portable power source housing 310 is further provided with a key opening 311 and a light guide opening 312 corresponding to the key 351 and the light guide 352. When the control board 350 is mounted in the mobile power supply case 310, the positions of the key 351 and the key opening 311 are matched, so that the user can activate the key 351; the location of light guide 352 matches the location of light guide aperture 312 so that a user can view light guide 352. Specifically, the user may turn on or off the mobile power supply 300 by activating the key 351; the light pipe 352 is used to provide corresponding indication information in order to enhance the user experience. For example, the light guide column 352 may indicate the power amount or the operating state (whether a fault occurs) of the mobile power source 300, and the like, which is not particularly limited in the embodiment of the present application.

The bottom of the supporting member 320 is further provided with a main board 360 (the main board 360 is located in the second space), and the main board 360 is provided with a control component for controlling the charging and power supply of the mobile power supply 300.

Because the power consumption of the power storage device 330 and the main board 360 is large and the heat generation is serious, the heat conducting member 370 is further disposed at the bottom of the main board 360, and the heat dissipating member 380 is further disposed at the bottom of the heat conducting member 370, so as to improve the heat dissipating effect. Specifically, the heat conducting element 370 may be fixed to the bottom of the main board 360 by means of adhesion, and the bottom of the heat dissipating element 380 is further provided with a heat dissipating rib 381, so as to increase the heat dissipating area of the heat dissipating element 380 and improve the heat dissipating effect. In a specific implementation, the heat sink 380 may be made of a material with a good thermal conductivity, such as aluminum, copper, and the like, which is not limited in this embodiment.

In other embodiments, the heat sink 380 may also be a heat dissipation fan powered by the power storage device 330, and the heat dissipation fan accelerates the flow of air near the power storage device 330 and the main board 360 to achieve air cooling, because a heat dissipation hole may also be provided on the mobile power supply housing 310 to enable the air to flow rapidly.

In order to facilitate fixing of the first power line 411, a power line fixing member 340 is further provided in the portable power source housing 310. The power cord holder 340 is disposed in the first space on a side of the power storage device 330 close to the top of the portable power source case 310, and one end of the first power cord 411 can be fixed inside the portable power source case 310 by the power cord holder 340. The other end of the first power line 411 is connected to the first connection end 221 of the power connector 200, so as to connect the power connector 200 and the mobile power source 300 together. Specifically, the power line fixing part 340 may be a line pressing plate, and the line pressing plate presses one end of the first power line 411 between the line pressing plate and the mobile power supply housing 310, so as to fix the first power line 411. Of course, other fixing manners can be adopted by those skilled in the art, and the embodiment of the present application is not particularly limited thereto.

Normally, the first connection end 221 of the power connector 200 is in a fixed connection state with the mobile power source 300 (as shown in fig. 7), and a user only needs to plug and unplug the second connection end 222 and the third connection end 223 of the power connector 200 when using the mobile power source. Of course, those skilled in the art may also set the first connection end 221 of the power connector 200 and the mobile power source 300 to be connected in a pluggable manner according to actual needs, which is not limited in this embodiment of the application.

It should be noted that the product form of the surface cleaning apparatus 100 is not limited in the embodiments of the present application. For ease of understanding, the operation of the surface cleaning apparatus 100 will be briefly described below in connection with two different product configurations.

The surface cleaning device I comprises:

fig. 8 is a schematic structural diagram of a surface cleaning apparatus according to an embodiment of the present disclosure. As shown in fig. 8, the surface cleaning apparatus includes a main body, and an adsorption unit 110 is disposed at a bottom of the main body, and the adsorption unit 110 can adsorb the surface cleaning apparatus on a surface to be cleaned. Specifically, the suction unit 110 may be a cavity disposed at the bottom of the main body, the cavity being used to define a sealed space with a surface to be cleaned (e.g., glass), and when a negative pressure is generated in the sealed space, the surface cleaning apparatus is sucked on the surface to be cleaned.

The bottom of the main body is further provided with a walking unit 120, and the walking unit 120 is used for driving the surface cleaning device to walk on the surface to be cleaned. Specifically, the traveling unit 120 may be a wheel type traveling unit or a crawler type traveling unit, or the like. It will be appreciated that the main body should also be provided with a drive unit which cooperates with the walking unit 120, by means of which the walking unit 120 can be driven to operate in order to drive the surface cleaning apparatus to walk over the surface to be cleaned.

It should be noted that fig. 8 is only an exemplary illustration of the surface cleaning device according to the embodiment of the present application, and should not be taken as a limitation to the scope of the present application.

For example, in one possible implementation, the bottom of the main body is also provided with a cleaning unit. When the surface cleaning device walks on the surface to be cleaned, the surface to be cleaned can be cleaned through the cleaning unit. Specifically, the cleaning unit may be a rolling brush, a wiping unit, or the like, and the wiping unit may be a sponge, cloth, paper, or the like.

In a possible implementation, a vacuum unit is also provided on the main body. The vacuum unit is used to generate a negative pressure in the adsorption unit 110. Specifically, the vacuum unit may be a pump or a blower, or the like.

A second surface cleaning device:

referring to fig. 9, a schematic structural diagram of another surface cleaning apparatus provided in the embodiments of the present application is shown. As shown in fig. 9, the self-moving cleaning apparatus includes a first cleaning unit 130, the first cleaning unit 130 is configured to define a first space with a surface to be cleaned, and when a negative pressure is generated in the first space, the first cleaning unit 130 can be adsorbed on the surface to be cleaned; the second cleaning unit 140, the second cleaning unit 140 is used for defining a second space with the surface to be cleaned, and when negative pressure is generated in the second space, the second cleaning unit 140 can be adsorbed on the surface to be cleaned; a link arm 150, a first end of the link arm 150 being connected with the first cleaning unit 130 by a first pivot 151, and a second end of the link arm 150 being connected with the second cleaning unit 140 by a second pivot 152; and the driving unit is used for driving the first cleaning unit 130 to rotate relative to the second cleaning unit 140, driving the second cleaning unit 140 to rotate relative to the first cleaning unit 130, and further driving the self-moving cleaning device to walk on the surface to be cleaned. It is understood that, in this embodiment, the first cleaning unit 130 and the second cleaning unit 140 simultaneously correspond to the traveling unit of the surface cleaning apparatus.

Referring to fig. 10, a schematic walking diagram of the surface cleaning apparatus shown in fig. 9 is provided according to an embodiment of the present application. As shown in fig. 10, in the initial position, the first cleaning unit 130 is located at a position P1, and the second cleaning unit 140 is located at a position P2; controlling the second cleaning unit 140 to be stationary, the first cleaning unit 130 to rotate in the direction T1 relative to the second cleaning unit 140, and the first cleaning unit 130 to reach the position P3; the first cleaning unit 130 is controlled to be stationary, the second cleaning unit 140 is rotated in the direction T2 with respect to the first cleaning unit 130, and the second cleaning unit 140 reaches the position P4. By analogy, the first cleaning unit 130 and the second cleaning unit 140 alternately walk to realize the walking of the surface cleaning device on the surface to be cleaned.

It should be noted that fig. 9 is only an exemplary illustration of the surface cleaning device according to the embodiment of the present application, and should not be taken as a limitation to the scope of the present application.

For example, in one possible implementation, the surface cleaning apparatus further includes a vacuum unit for communicating the first space and the second space, so that the first space and the second space generate a negative pressure, and the first cleaning unit 130 and the second cleaning unit 140 are adsorbed on the surface to be cleaned.
