Detailed Description

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 of 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.

As shown in fig. 1, a dust collecting apparatus 1 described in the embodiment of the dust collecting apparatus of the present application may include: a device body 10 and a dirt cup 20. The apparatus body 10 may be connected with a dirt cup 20. The device body 10 is used for providing a suction force to generate a negative pressure in the dust cup 20, so that the garbage objects can be sucked into the dust cup 20 along with the airflow through the air inlet pipe 118 and then remain in the dust cup 20. The dirt cup 20, which may also be referred to as a dirt box, is used to collect trash objects. The trash objects may include dust, debris, hair, and the like.

As shown in fig. 2, the device body 10 may include a housing 110 and a separation assembly 120. The housing 110 may be used to house the associated components for corresponding protection. For example, at least a portion of the separation assembly 120 is disposed within the housing 110. The separating assembly 120 can be used to draw a flow of air into an airstream that creates a negative pressure within the dirt cup 20. The trash items can enter the dirt cup 20 with the airflow under negative pressure. The separating assembly 120 can also be used to separate air from trash objects that are separated and retained within the dirt cup 20. Of course, the device body 10 may further include a battery 130, and the battery 130 may be accommodated in the case 110. The battery 130 may provide electrical power to the separation assembly 120 and the like.

Optionally, the housing 110 may be provided with an accommodating cavity 111, and at least a portion of the separating assembly 120 may be accommodated in the accommodating cavity 111. The housing 110 may be opened with a battery compartment 112. The battery 130 may be housed within the battery compartment 112. The accommodating cavity 111 can be communicated with the battery bin 112. The separator assembly 120 may be in communication with the battery compartment 112. Separation assembly 120 may be particularly useful for creating a flow of gas from outside separation assembly 120 to inside separation assembly 120. The airflow created by the separating assembly 120 may enter the dirt cup 20 from outside the dirt cup 20 and then flow from outside the separating assembly 120 into the separating assembly 120. The trash objects are trapped outside the separator assembly 120 and remain within the dirt cup 20. The airflow can further flow into the battery compartment 112 from the separating assembly 120, so that the airflow in the battery compartment 112 can be accelerated, the heat of the battery 130 can be taken away, the reliability of the working environment of the battery 130 can be improved, and the discharging efficiency and the service life of the battery 130 can be further improved. The airflow may be exhausted from the battery compartment 112 after passing through the batteries 130 to remove heat therefrom.

Alternatively, as shown in fig. 3, the battery compartment 112 may be disposed around the accommodating cavity 111. That is, the battery compartment 112 can surround the periphery of the battery compartment 112, so that a larger annular battery compartment 112 can be formed, the heat dissipation space of the battery 130 is increased, air flow is facilitated, and heat can be taken away more quickly. The annularly disposed battery compartment 112 also facilitates the arrangement of the batteries 130. For example, the battery 130 may include a plurality of battery cells 131 coupled to each other, and the plurality of battery cells 131 may be disposed at intervals in the battery compartment 112. Specifically, a plurality of cells 131 may be disposed at intervals around the axis of the battery compartment 112. Further, the extending direction of the battery compartment 112 may be the same as the extending direction of the accommodating cavity 111. The extending direction is also the length direction. Of course, the accommodating cavity 111 may be a cylindrical cavity, and the accommodating cavity 111 and the battery compartment 112 may be coaxially disposed, in which case, the extending direction is the axial direction.

Alternatively, the housing 110 may be formed with a communication chamber 113. The communication chamber 113 may communicate the accommodation chamber 111 and the battery compartment 112. Specifically, one end of the battery compartment 112 may communicate with the communication chamber 113. The bottom of the receiving chamber 111 may communicate with the communication hole 114. The end of the accommodating cavity 111 opposite to the bottom thereof is an opening, and the separating element 120 can be accommodated in the accommodating cavity 111 through the opening. Further, the bottom of the receiving cavity 111 may be opened with a communication hole 114. The communication hole 114 may communicate the accommodation chamber 111 and the communication chamber 113. Through be provided with intercommunication chamber 113 between battery compartment 112 and holding chamber 111, can play even effect to the air current, and then noise abatement, also can form bigger cavity moreover, the thermal giving off of battery 130 of being convenient for the air current can take away the heat of battery 130 better, reduces the surface temperature of battery 130.

Optionally, a shock absorbing gasket 116 may be disposed between the separating assembly 120 and the bottom of the receiving cavity 111. The shock absorbing gasket 116 may abut between the separating member 120 and the bottom of the receiving chamber 111. The shock-absorbing packing 116 may surround the communication hole 114 such that the separation member 120 communicates with the communication hole 114. So can improve the leakproofness, reduce the air current and reveal in the holding chamber 111 outside the separator assembly 120, and enter into communicating chamber 113 and battery compartment 112 more, promote the radiating effect of battery 130, also can guarantee dust extraction 1's adsorption affinity.

Optionally, the device body 10 may include an annular filter 117. Specifically, one end of the battery compartment 112 may communicate with the accommodating cavity 111, and the annular filter 117 may be accommodated at one end of the battery compartment 112 to filter the air flow. In other words, the annular filter 117 is disposed around the accommodating cavity 111 and further accommodated at one end of the battery compartment 112. The annular filter 117 may further filter the airflow as it passes through the communication cavity 113 and into the battery compartment 112 to reduce the contamination of the battery compartment 112 by the airflow. The annular filter 117 is, for example, a high efficiency filter (HEPA). Further, an air outlet 115 communicating with the battery compartment 112 is circumferentially opened on the outer peripheral side of the battery compartment 112 adjacent to the other end thereof to discharge the air flow. That is, the outlet 115 may be formed in an annular shape, and may be an open annular shape or a closed annular shape. The number of the outlet vents 115 may be at least one. The air outlet 115 is formed in the outer peripheral side of the other end of the battery bin 112, so that the air flow has a longer stroke in the battery bin 112, can better contact with the battery cell 131, further the air outlet 115 is formed in the circumferential direction, the air outlet efficiency can be improved, and the air flow is accelerated.

The separation assembly 120 may include a fan for creating an airflow and a separator, which may be a cyclone or a filter, for dust-gas separation. Of course, the separating assembly 120 may also be a separating assembly 120 conventional in the art.

The inventor of the present application has found that the filter is easily blocked by dust to cause the loss of the filtering function, which affects the working effect of the whole dust suction apparatus 1, and the cyclone separator causes the pressure loss of the whole dust suction apparatus 1 to be large, so that it is difficult to improve the suction power and efficiency of the dust suction apparatus 1. For this reason, the separation assembly 120 of the present embodiment may be configured as a centrifugal separation assembly 120a, which separates the garbage object and the airflow by the centrifugal force, so as to improve the above technical problem.

For the centrifugal separation assembly 120a, reference may be made to the following detailed description of the embodiments of the centrifugal separation assembly of the present application.

As shown in fig. 2 and 4, a centrifugal separation assembly 120a described in embodiments of the centrifugal separation assembly of the present application may include a motor housing 121, a fan housing 122, a drive member 123, an impeller 124, and a separator 125.

The fan housing 122 may be coupled to one end of the motor housing 121, and the inside of the fan housing 122 and the inside of the motor housing 121 may communicate. Optionally, the fan housing 122 and the motor housing 121 are integrally formed. Of course, the fan housing 122 and the motor housing 121 may be provided separately and may be assembled and connected.

The motor housing 121 may be provided in a cylindrical shape. The fan housing 122 may be cylindrical. One end of the fan housing 122 is connected to one end of the motor housing 121 and communicated with each other. Alternatively, the diameter of one end of the fan housing 122 may be smaller than or equal to the diameter of one end of the motor housing 121. The other end of the fan housing 122 may communicate with the communication cavity 113. The other end of the motor housing 121 may communicate with the separator 125. The motor housing 121 and the fan housing 122 may form a relatively closed air passage, and may further form a relatively closed air passage with the communication chamber 113 and the separating member 125.

The impeller 124 may be disposed inside the fan housing 122. The driving member 123 may be disposed inside the motor housing 121, and the separating member 125 may be disposed at the other end of the motor housing 121 and outside the motor housing 121. The output shaft 1231 of the driving member 123 may be drivingly connected to the impeller 124 and the separating member 125, respectively, for driving the impeller 124 and the separating member 125 to rotate. The output shaft 1231 of the driving member 123 can drive the impeller 124 and the separating member 125 to rotate at the same time, and the separating member 125 can generate a centrifugal force during the rotation process, so as to "throw away" the garbage objects by using the centrifugal force, and then fall into the dust cup 20.

Impeller 124 and separator 125 are connected through the output shaft 1231 that sets up driving piece 123, and then can drive impeller 124 and separator 125 simultaneously and rotate, can realize centrifugal separation's effect for rubbish object can be separated more effectively, improves separation efficiency effectively, and then can improve filtration efficiency. Compared with the impeller 124 and the separating element 125 which respectively need one driving element 123, the present embodiment effectively achieves the effect of "one motor is multifunctional", can save components, and structurally also enables the structure to be more compact, save volume, lighter in weight and lower in energy consumption. But also can lead the dust collection and the dust-air separation to be more coordinated and synchronous, and can improve the dust collection and the dust-air separation effect.

The driving member 123 is, for example, a motor, and specifically, may be a servo motor or a stepping motor. The battery 130 can provide power to the driving member 123 to make it work normally. Impeller 124 may have fan blades 1241 and impeller 124 may be used to create an airflow through separator 125 out into separator 125 by rotating. The separating member 125 may be used to separate trash objects from air. In particular, the separating member 125 may be used to generate centrifugal force by rotation. When the garbage objects contact the separating member 125 along with the airflow, the garbage objects are separated by the centrifugal force and fall into the dust cup 20, and the airflow continues to enter the separating member 125 and then enters the communicating chamber 113.

To better increase the pressure and velocity of the airflow entering the battery compartment 112, the centrifugal separation assembly 120a described in this embodiment may further include a pressure booster 126, also referred to as a diffuser, for boosting the pressure of the airflow entering the communication chamber 113/battery compartment 112. Specifically, the supercharger 126 may be disposed at the other end of the fan housing 122, and is configured to supercharge the airflow passing through the impeller 124, so that the supercharged airflow flows into the communication cavity 113. Therefore, the speed of the airflow in the battery compartment 112 can be effectively increased, and the heat of the battery 130 can be taken away more quickly, so as to protect the battery 130. The supercharger 126 in this embodiment may be an existing supercharger 126.

Alternatively, the separating member 125 and the impeller 124 may be located on the same side of the drive member 123 or may be located on different sides of the drive member 123. Further, the output shaft 1231 of the driving member 123 may extend to opposite sides of the driving member 123, and the separating element 125 and the impeller 124 may be located at different sides of the driving member 123, so that the separating element 125 and the impeller 124 can be better arranged, the possibility of mutual interference between the separating element 125 and the impeller 124 during the rotation process is reduced, and the rotation of the separating element 125 and the impeller 124 is smoother.

Since there may be differences in the rotational speeds required for centrifugation and suction, the centrifuge assembly 120a may further include a gearbox 127. The gearbox 127 is, for example, a reduction gearbox, and the rotational speed output through the gearbox 127 is lower than the rotational speed of the output shaft 1231 of the driver 123 itself. The gearbox 127 may be disposed inside the motor housing 121.

The output shaft 1231 of the driver 123 may be connected to the impeller 124 on one side of the driver 123. The output shaft 1231 of the driver 123 is connected to the gearbox 127 on the other side of the driver 123. In this regard, the present embodiment may have two cases, one is that the transmission case 127 has a separate input shaft, and the output shaft 1231 of the driving member 123 is connected with the input shaft of the transmission case 127, for example, by a coupling, a gear or a belt; alternatively, the output shaft 1231 of the driver 123 may be directly used as the input shaft of the gearbox 127, and this may also be considered as the output shaft 1231 of the driver 123 being connected to the input shaft of the gearbox 127 on the other side of the driver 123. An output shaft 1271 of the transmission case 127 can be connected to the separating element 125, and can drive the separating element 125 to rotate.

For the content of the separating member 125 of the present embodiment, reference may be made to the following detailed description of the embodiments of the separating member 125 of the present application.

As shown in fig. 4, the separating member 125 described in this embodiment may be a filter screen structure. Specifically, separator 125 may include a sidewall 1251 and a bottom wall 1252. Side wall 1251 may be cylindrical and side wall 1251 may be joined to bottom wall 1252 to enclose a filter chamber 1250. That is, side wall 1251 and bottom wall 1252 may collectively enclose a filter chamber 1250. The gas flow can flow from outside filter cavity 1250 into filter cavity 1250, thereby allowing trash objects to be trapped outside filter cavity 1250. The sidewall 1251 may be provided in a straight cylindrical shape or in a tapered shape. The drive member 123 may be used to drive the separator 125 about the axis of the sidewall 1251 to effect centrifugal separation.

Specifically, side wall 1251 is closer to driver 123 than bottom wall 1252. Further, the side wall 1251 may be disposed opposite the other end of the motor housing 121.

Further, separator 125 may also include a top wall 1253. Side walls 1251 may be connected between top wall 1253 and bottom wall 1252 and may collectively define a filter chamber 1250. One end of side wall 1251 may be connected to top wall 1253 and the other end of side wall 1251 may be connected to bottom wall 1252. The top wall 1253 may face the motor housing 121 and may abut the other end of the motor housing 121. And the other end of the bottom wall 1252 may face away from the motor housing 121. The side wall 1251 may further be tapered with a diameter that tapers from the top wall 1253 to the bottom wall 1252. An output shaft 1271 of the transmission 127 may be connected to the top wall 1253. Further, the output shaft 1271 of the gearbox 127 can be arranged through the top wall 1253 and further connected with the bottom wall 1252, so that the output shaft 1271 of the gearbox 127 has a better supporting effect and a better fixing effect on the separating element 125.

The filter chamber 1250 may communicate with the interior of the motor housing 121 through the top wall 1253. Specifically, the top wall 1253 may be opened with a through-flow hole 1254 communicating with the filter chamber 1250, and the filter chamber 1250 may communicate with the inside of the motor housing 121 through the through-flow hole 1254. In this way, the air flow can enter the filter cavity 1250 from the outside of the separating member 125, and then sequentially flows through the motor housing 121 and the fan housing 122 through the through-hole 1254, and then enters the communication cavity 113.

To improve the sealing between the separating member 125, the motor housing 121 and the fan housing 122, the centrifugal separation assembly 120a described in this embodiment may further include a wear-resistant seal 1255. The wear-resistant seal 1255 may be a rubber seal, a ceramic seal, or a silicone seal, among others. A wear seal 1255 is attached to the other end of the motor housing 121 and may abut the top wall 1253 or the side wall 1251. Either the side wall 1251 or the bottom wall 1252 may abut the wear seal 1255 during rotation and may rotate relative to the wear seal 1255, thus maintaining a seal during rotation as well. Of course, the wear seal 1255 can be coupled to either the top wall 1253 or the side wall 1251 such that the wear seal 1255 can rotate relative to the other end of the motor housing 121 as the side wall 1251 rotates.

A wear seal 1255 may surround the flow aperture 1254. So can make the periphery of through-flow hole 1254 sealed, and then the air current that through-flow hole 1254 flowed out can flow into motor casing 121 in better, guaranteed dust extraction 1's adsorption efficiency and cleaning performance on the one hand, on the other hand also can guarantee the radiating effect of battery 130.

In the separator 125, at least the side wall 1251 may be opened with a filter hole 1256 communicating with the filter chamber 1250. The air flow can pass through the filter openings 1256 into the filter chamber 1250 while the debris objects are separated by centrifugal force. Specifically, as shown in fig. 5, the axis of the filter aperture 1256 may not intersect the axis of the sidewall 1251. That is, the axial direction of the filter apertures 1256 is different from the radial direction of the side walls 1251. In other words, the filtering holes 1256 may be inclined holes.

As shown in fig. 5, the included angle α between the axial direction m of the filter holes 1256 from the outside of the filter chamber 1250 to the inside of the filter chamber 1250 and the tangential direction n of the side wall 1251 to the tangent of the filter holes 1256 is acute. The included angle alpha is, for example, 20 deg. -80 deg., optionally 30 deg. -60 deg., optionally 45 deg.. The tangent of the sidewall 1251 to the filter aperture 1256 may refer to a tangent on the outer circumferential surface of the sidewall 1251 passing through the center of the aperture of the filter aperture 1256 outside the filter chamber 1250. The tangent to this tangent is related to the direction of rotation of the sidewall 1251, which may be directed in the direction of rotation, which is shown in fig. 5 as being counterclockwise. The center of the opening of the filtering hole 1256 may be a circle center, a geometric center or a geometric center of gravity, etc. The axes of the filter apertures 1256 intersect their corresponding tangents.

Through the structural arrangement of the filtering holes 1256, the hole opening of the filtering hole 1256 outside the filtering cavity 1250 is similar to the rotation direction, the hole opening of the filtering hole 1256 outside the filtering cavity 1250 and the hole opening of the filtering cavity 1250 form similar 'tandem' in the rotation direction, the direct flushing of the airflow flowing into the filtering hole 1256 from the dust cup 20 can be reduced, and then the entering of garbage objects into the filtering cavity 1250 is reduced, the centrifugal separation effect is improved, meanwhile, the garbage objects can be prevented from blocking the filtering hole 1256, the smoothness of the airflow flowing into the filtering cavity 1250 is improved, and the adsorption force of the dust collection device 1 is ensured.

Alternatively, FIG. 6 illustrates an exemplary aspect of detail H in FIG. 4, where the openings of filter apertures 1256 outside filter chamber 1250 may be closer to bottom wall 1252 than the openings in filter chamber 1250, as shown in FIG. 6. Like this, the drill way at the both ends of filtering hole 1256 forms the effect of similar "one is high one low", and the drill way outside is lower moreover, and the drill way inside is higher, so can further reduce the probability that rubbish object gets into filtering hole 1256, further prevent that rubbish object from blockking up filtering hole 1256.

Optionally, the side wall 1251 may be provided with a set of filter holes 1256 along a circumferential direction thereof, and the number of each set of filter holes 1256 may be at least one, for example, a plurality of filter holes arranged at intervals, and specifically, may be 24. The side wall 1251 may be provided with a plurality of sets of filter apertures 1256 spaced axially therealong. The number of the filter holes 1256 may be the same or different from each other in the axial direction of the side wall 1251. Through setting up and set up multiunit filtration hole 1256 at lateral wall 1251, improve filter effect and adsorption efficiency effectively.

Of course, the bottom wall 1252 may also be perforated with filter holes 1256. The axis of the bottom wall 1252 in which the filter apertures 1256 are provided does not coincide with the axis of the side wall 1251.

Through the above-mentioned structure setting of filtering holes 1256, the separating member 125 can perform centrifugal separation of garbage objects well in the rotating process, and reduce the probability of blockage of the filtering holes 1256, so that cleaner airflow enters the filtering cavity 1250 and garbage objects are retained in the dirt cup 20.

For details of the dirt cup 20 in the embodiments of the present cleaning device, reference is made to the following detailed description of the embodiments of the present dirt cup assembly.

The dirt cup assembly described in the present embodiments of the dirt cup assembly can include a dirt cup 20 and a separator.

Taking the snap structure as an example, as shown in fig. 7, the dirt cup 20 can include a snap 230, and the fixed cup 210 and the disposable cup 220 can be snapped together by the snap 230. The fixed cup body 210 and the disposable cup body 220 are connected through the fastener 230, so that the quick connection and disassembly can be realized, and the cleaning efficiency is improved. Optionally, to achieve a good negative pressure in the dirt cup 20 to ensure dust collection, the connection between the fixed cup 210 and the disposable cup 220 can be provided with a sealing ring 250. The sealing ring 250 can abut against the fixed cup 210 and the disposable cup 220, thereby reducing air flow leakage, ensuring larger negative pressure and reducing loss of adsorption force.

Specifically, as shown in fig. 7 and 8, the latch 230 may include a support sub 231 and a latch sub 232. The clamping sub-element 232 is rotatably connected to the support sub-element 231. There are many situations in the connection between the catch sub 232, the support sub 231, the fixing cup 210, and the disposable cup 220.

In the first case: as shown in fig. 8, the support sub 231 may be fixedly coupled to the fixing cup 210. The catch sub 232 is used to catch the disposable cup 220 to enable catching or releasing by rotation relative to the support sub 231.

In the first case, the disposable cup 220 can be provided with a locking groove 240 on the outer circumference, and the locking sub-member 232 can be provided with a locking hook 2321 in a protruding manner. The hook 2321 can extend to the slot 240 and be engaged with the edge of the slot 240. Fig. 7 shows the hook 2321 being engaged with the edge of the card slot 240. Specifically, the hooking portion 2321 may be hooked to an edge of the engaging groove 240 close to the fixing cup 210. Optionally, the clamping groove 240 is opened at the periphery of the opening end along the circumferential direction of the disposable cup 220, and the clamping groove 240 can be annularly arranged, so that the clamping hook portion 2321 and the clamping groove 240 do not need to be aligned when the fixed cup 210 and the disposable cup 220 are assembled, and the blind assembly can be realized, and the assembly efficiency is improved.

In particular, the supporting sub-member 231 may be cylindrically disposed. For example, the support sub 231 may be configured as a flat, cylindrical structure. One end of the support sub 231 can have a portion that is fixedly attached to the fixed cup 210 and another portion that extends beyond the fixed cup 210 for attaching to the edge of the disposable cup 220. Specifically, one end of the fixed cup 210 may be used to connect the shell 110, and a portion of one end of the supporting sub 231 may be fixedly connected to the other end of the fixed cup 210 and another portion extends over a rim of the other end of the fixed cup 210. When the fixed cup 210 and the disposable cup 220 are connected, another portion of the end of the support sub 231 can pass over the connection between the fixed cup 210 and the disposable cup 220.

The clip sub 232 may be rotatably coupled within the support sub 231 and exposed through the other end of the support sub 231. The catch sub 232 is exposed through the other end of the support sub 231 to be operable, e.g., pressed, to effect rotation. Hook 2321 may be disposed at an end of clip sub-assembly 232 away from stationary cup 210. In other words, the hook 2321 can be disposed at one end of the snap sub 232 extending beyond the edge of the fixing cup 210, and can extend to the snap groove 240 when the fixing cup 210 and the disposable cup 220 are connected.

Specifically, as shown in fig. 8, two opposite side walls of the clip member 232 may be provided with rotating portions 2322. The rotating part 2322 is, for example, a rotating shaft or a pin. The supporting holes 2311 are formed on two opposite side walls of the supporting sub-element 231. The rotating portion 2322 is rotatably inserted into the support hole 2311. As shown in fig. 9, an end of the clip sub-member 232 away from the hook 2321 may be wedge-shaped, and the thickness of the wedge-shaped end gradually decreases in a direction away from the hook 2321, so that the clip sub-member 232 can rotate relative to the support sub-member 231 by pressing the end of the clip sub-member 232 away from the hook 2321. The thickness of the clip sub 232 may refer to the thickness of the clip sub 232 in the direction from one end of the support sub 231 to the other end of the support sub 231. Specifically, the rotating portion 2322 is located between the wedge-shaped portion and the hooking portion 2321, and may form a lever-like structure.

Through the normal running fit who sets up rotation portion 2322 and support hole 2311, combine joint daughter 232 to keep away from the wedge setting of trip portion 2321 one end, the one end that trip portion 2321 was kept away from to joint daughter 232 can grow gradually with the distance of the outer peripheral face of fixed cup 210, and then allow to be pressed, when joint daughter 232 was pressed, the one end that trip portion 2321 was kept away from to joint daughter 232 can approach the outer peripheral face of fixed cup 210 gradually, because lever principle, trip portion 2321 can be "lifted", and then realize the dropout, so can realize pressing of joint daughter 232 effectively and rotate, moreover, the steam generator is simple in structure and reliable.

Optionally, the number of the clasps 230 is at least two, and the at least two clasps 230 are disposed at intervals on the fixed cup 210. At least two latches 230 may latch with the same latch slot 240. Of course, at least two latches 230 may also latch with different slots 240.

In the second case: the supporting sub 231 is fixedly connected to the disposable cup 220, and the snap sub 232 is used for snapping the fixing cup 210 so as to be able to snap or release by rotating relative to the supporting sub 231. Optionally, the number of the clasps 230 is at least two, and the at least two clasps 230 are arranged at intervals on the outer circumference of the disposable cup 220.

For the specific structure of the second case, reference may be made to the description of the first case, which differs from the second case only in that: the attachment location of the support sub 231 and the accommodation of the snap sub 232 changes.
