Description

Technical Field

[0001] The present application relates to the technical field of household cleaning appliances, and particularly to a dust cup structure and a cleaning device. Background Art

[0002] With the continuous development of technology and the improvement of people's living standards, household dust removal devices such as cleaning devices (such as vacuum cleaners, floor washers, etc.) have increasingly appeared in people's lives.

[0003] Currently, a cleaning device may include a device body and a dust cup structure. The device body sprays water onto the surface to be cleaned and generates suction to suck liquid impurities and solid impurities on the surface to be cleaned into the dust cup structure. In order to reduce the risk of liquid impurities entering the device body and affecting the operation of the motor, in related technologies, a gas-liquid separation component is added to the device body to additionally achieve the collection of liquid impurities.

[0004] However, in the prior art, the separated liquid impurities in the cleaning device are mixed with more solid impurities to form sludge and adhere to the dust cup structure, and the separation effect of the liquid impurities and the solid impurities is poor. Summary of the Invention

[0005] Based on this, the present application provides a dust cup structure and a cleaning device, which realize the separation of liquid impurities and solid impurities by adding a gas-liquid separation function in the dust cup structure, and the separation effect is better.

[0006] In a first aspect, the present application provides a dust cup structure, including a dust cup main body, a gas-liquid separation component, and a gas-dust separation component. The gas-liquid separation component and the gas-dust separation component are both located in the dust cup main body. The gas-dust separation component is located above the gas-liquid separation component and is communicated with the gas-liquid separation component.

[0007] In the dust cup structure provided by the present application, after the liquid impurities and the solid impurities are uniformly sucked into the dust cup main body, they first pass through the gas-liquid separation component for gas-liquid separation, and then pass through the gas-dust component for gas-dust separation, realizing the separation of the liquid impurities and the solid impurities, and the separation effect is better.

[0008] In a possible implementation manner, in the dust cup structure provided by the present application, a support member is provided in the dust cup main body. The support member is located inside the dust cup main body. The gas-liquid separation component is sleeved on the support member. A first dust collection cavity is formed between the support member and the inner wall of the dust cup main body. The gas-dust separation component is arranged on the support member.

[0009] In this way, the support member can not only provide an installation position for the gas-liquid separation component, but also form a first dust collection cavity between the support member and the inner wall of the dust cup main body, having the effect of multi-purpose use and improving the utilization rate of the support member.

[0010] In a possible implementation, for the dust cup structure provided by the present application, the support member is a support sleeve, the support sleeve is communicated with the air-dust separation component, and the inner wall of the support sleeve forms a second dust collection cavity.

[0011] In this way, the inner wall of the support sleeve forms a second dust collection cavity, and the outer wall forms a first dust collection cavity with the dust cup body, realizing the separate storage of liquid impurities and solid impurities, which is convenient for cleaning.

[0012] In a possible implementation, for the dust cup structure provided by the present application, it further includes a cup cover, the cup cover is provided at one end of the dust cup body facing away from the air-dust separation component, and one end of the support sleeve facing away from the air-dust separation component abuts against the cup cover.

[0013] In this way, the cup cover can simultaneously open and close the first dust collection cavity and the second dust collection cavity. It can be understood that when the user operates the cup cover once, the first dust collection cavity and the second dust collection cavity can be opened simultaneously, further improving the cleaning efficiency.

[0014] In a possible implementation, for the dust cup structure provided by the present application, the dust cup body has an air inlet communicated with the first dust collection cavity, and the air inlet is located between the air-liquid separation component and the cup cover;

[0015] The dust cup body has an air outlet, and the air outlet is communicated with the end of the air-dust separation component facing away from the air-liquid separation component.

[0016] In this way, the gas mixed with liquid impurities and solid impurities is inhaled into the first dust collection cavity through the air inlet, and then successively passes through the separation effects of the air-liquid separation component and the air-dust separation component. Finally, the gas separated from the liquid impurities and solid impurities is discharged from the dust cup body through the air outlet and then enters the cleaning device. The gas after separating the liquid impurities and solid impurities can reduce the failure rate of the motor in the cleaning device.

[0017] In a possible implementation, for the dust cup structure provided by the present application, the cup cover has a first connection part, the dust cup body has a second connection part, and the first connection part is detachably connected to the second connection part.

[0018] In this way, the cup cover and the dust cup body are detachably connected through the first connection part and the second connection part, which is convenient for operating the opening and closing of the cup cover and convenient for the user to operate.

[0019] In a possible implementation, for the dust cup structure provided by the present application, one of the first connection part and the second connection part is an external thread, and the other is an internal thread matching the external thread.

[0020] In this way, through the threaded connection of the internal thread and the external thread, the detachable connection between the first connection part and the second connection part is realized, which has the effects of simple structure, convenient operation and low manufacturing cost.

[0021] In a possible implementation, for the dust cup structure provided by the present application, the gas-liquid separation component includes a centrifugal fan and a power fan coaxially connected to the centrifugal fan. The power fan drives the centrifugal fan to rotate, and the power fan is located between the centrifugal fan and the gas-dust separation component.

[0022] In this way, when the gas-liquid separation component is working, the gas inhaled into the dust cup body is blown towards the power fan. The power fan rotates to drive the centrifugal fan to rotate. The centrifugal fan generates centrifugal force to separate the liquid impurities in the gas. By using the flow of the gas to generate centrifugal force, the energy of the gas flow can be fully utilized, improving the energy utilization rate.

[0023] In a possible implementation, for the dust cup structure provided by the present application, the gas-liquid separation component further includes a support frame. The support frame abuts against the inner side wall of the dust cup body. The support frame is arranged above the centrifugal fan, and the power fan is coaxially inserted into the centrifugal fan through the support frame.

[0024] In this way, the support frame provides an installation position for the power fan and the centrifugal fan, making the rotation of the power fan and the centrifugal fan more stable.

[0025] In a possible implementation, for the dust cup structure provided by the present application, the power fan has a first insertion part, and the centrifugal fan has a second insertion part. One of the first insertion part and the second insertion part is inserted into the other.

[0026] In this way, the power fan and the centrifugal fan are inserted through the first insertion part and the second insertion part, with a simple structure and convenient installation of the power fan and the centrifugal fan.

[0027] In a possible implementation, for the dust cup structure provided by the present application, at least one insertion block is provided on one of the first insertion part and the second insertion part, and a slot corresponding to the insertion block is provided on the other.

[0028] In this way, when the insertion block is inserted into the slot, the fixation of the first insertion part and the second insertion part can be achieved, facilitating the coaxial rotation of the power fan and the centrifugal fan.

[0029] In a possible implementation, for the dust cup structure provided by the present application, the support frame has a spiral air guide channel, and the air guide channel communicates the centrifugal fan and the power fan.

[0030] In this way, the gas inhaled into the dust cup body will form a spiral-flowing gas after passing through the spiral air guide channel. The spiral-flowing gas can drive the power fan to rotate more conveniently and quickly.

[0031] In a possible implementation, for the dust cup structure provided by the present application, the gas-liquid separation component further includes a first bearing. The first bearing is sleeved on the support member and is connected to the centrifugal fan.

[0032] In this way, the centrifugal fan is rotationally connected to the support member through the first bearing, which can make the rotation of the centrifugal fan smoother. In addition, the first bearing also provides a support point for the centrifugal fan, making the rotation of the centrifugal fan more stable.

[0033] In a possible implementation manner, for the dust cup structure provided by the present application, the gas-liquid separation component further includes a bearing cover, which is sleeved on the support member and abuts against the first bearing.

[0034] In this way, on the one hand, the bearing cover can play a role in positioning the first bearing, and on the other hand, it also has the functions of dust prevention and sealing, effectively preventing impurities from entering the inside of the first bearing and affecting the operation of the first bearing.

[0035] In a possible implementation manner, for the dust cup structure provided by the present application, the gas-liquid separation component further includes a second bearing and a mounting bracket. The mounting bracket is arranged at the end of the power fan facing away from the centrifugal fan. The mounting bracket is connected to the support bracket, and the second bearing is arranged on the mounting bracket.

[0036] In this way, the power fan is rotationally connected to the mounting bracket through the second bearing, which can make the rotation of the power fan smoother. In addition, the second bearing also provides a support point for the power fan, making the rotation of the power fan more stable.

[0037] In a possible implementation manner, for the dust cup structure provided by the present application, a plurality of guiding grooves are formed in the side wall of the centrifugal fan. Each guiding groove is inclined, and the inclination directions of all the guiding grooves are the same, and the inclination direction of each guiding groove is the same as the direction of the power fan.

[0038] In this way, the inclination direction of each guiding groove is the same as the direction of the power fan, which is convenient for the centrifugal fan to generate centrifugal force and then throw the liquid impurities out of the centrifugal fan through the guiding grooves.

[0039] In a second aspect, the present application provides a cleaning device, including a device main body and the above-mentioned dust cup structure, and the dust cup structure is connected to the device main body.

The described embodiments are some, but not all, of the embodiments of the present application. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and should not be construed as a limitation to the present application.

[0056] Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application. The following will explain in detail the embodiments of the present application with reference to the drawings.

[0057] In the description of the present application, it should be noted that, unless otherwise clearly defined and limited, the terms "install", "connect", and "couple" should be understood in a broad sense. For example, it may be a fixed connection, or an indirect connection through an intermediate medium, or the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0058] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is the orientation or positional relationship based on the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0059] The terms "first", "second", "third" (if any) in the description and claims of the present application and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0060] In addition, the terms "comprise" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or display that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or displays.

[0061] As described in the background art, in the cleaning device in the related art, the liquid impurities separated by the cleaning device are mixed with a large amount of solid impurities to form sludge, which adheres to the dust cup structure. The separation effect of the liquid impurities and the solid impurities is poor, and thus it is time-consuming and laborious to clean the cleaning device.

[0062] After research, it is found that the reason for this problem is that the cleaning device sucks the liquid impurities and solid impurities on the surface to be cleaned into the dust cup structure together, and performs gas-liquid separation on the gas in the dust cup structure. However, some solid impurities are mixed in the separated liquid impurities and form sludge adhering to the side wall of the dust cup structure. After the cleaning device is used up, or when the impurities in the dust cup structure accumulate to a large amount, the cleaning device needs to be cleaned, and it is extremely inconvenient to clean the adhered sludge.

[0063] In view of the above problems, the present application provides a dust cup structure and a cleaning device. The dust cup structure includes a dust cup main body, a gas-liquid separation component and a gas-dust separation component. The gas-liquid separation component and the gas-dust separation component are both located in the dust cup main body. The gas-dust separation component is located above the gas-liquid separation component and is communicated with the gas-liquid separation component.

[0064] Thus, the gas sucked into the dust cup structure will separate the liquid impurities and the solid impurities under the combined action of the gas-liquid separation component and the gas-dust separation component, and the separation effect is better than that of the prior art.

[0065] The following will describe in detail the specific implementation manners of the dust cup structure and the cleaning device provided by the embodiments of the present application with reference to the accompanying drawings.

[0066] It should be noted that Figures 1 to 5 schematically shows a simplified schematic diagram of each component in the dust cup structure and the cleaning device. The specific structures of the other components in the dust cup structure and the cleaning device are not limited to Figures 1 to 5 the illustration.

[0067] It should be further noted that the dust cup structure provided by the present application can be applied to various different cleaning devices. Specifically, when implemented, the cleaning device has a motor assembly that provides suction force, and the dust cup structure is used to connect to the motor assembly.

[0068] Referring to Figures 1 to 3 as shown, the present application provides a dust cup structure, including: a dust cup main body 100, a gas-liquid separation component 200 and a gas-dust separation component 300. The gas-liquid separation component 200 and the gas-dust separation component 300 are both located in the dust cup main body 100. The gas-dust separation component 300 is located above the gas-liquid separation component 200 and is communicated with the gas-liquid separation component 200.

[0069] Here, the dust cup body 100 is a related technology in this field, and its specific structure is not limited here. The gas-dust separation component 300 can achieve the separation of gas and solid impurities, and its specific structure is not limited here.

[0070] In the dust cup structure provided by this application, after liquid impurities and solid impurities are uniformly sucked into the dust cup body 100, they first pass through the gas-liquid separation component 200 for gas-liquid separation, and then pass through the gas-dust component for gas-dust separation, realizing the separation of liquid impurities and solid impurities, with a good separation effect, which can facilitate the user to clean and reduce the user's workload.

[0071] In other possible implementation manners, there is a support member 400 in the dust cup body 100. The support member 400 is located inside the dust cup body 100, and the length direction of the support member 400 can be set along the extension direction of the dust cup body 100, so as to make full use of the internal space of the dust cup body 100.

[0072] The gas-liquid separation component 200 is sleeved on the support member 400. A first dust collection cavity 110 is formed between the support member 400 and the inner wall of the dust cup body 100, and the gas-dust separation component 300 is arranged on the support member 400.

[0073] In this way, the support member 400 can not only provide an installation position for the gas-liquid separation component 200, but also form a first dust collection cavity 110 with the inner wall of the dust cup body 100, having the effect of multi-purpose use of one object and improving the utilization rate of the support member 400.

[0074] The support member 400 is a support sleeve, and the support sleeve is communicated with the gas-dust separation component 300. The inner wall of the support sleeve forms a second dust collection cavity 410.

[0075] The inner wall of the support sleeve forms a second dust collection cavity 410, and the outer wall forms a first dust collection cavity 110 with the dust cup body 100, realizing the separate storage of liquid impurities and solid impurities without interference with each other, which is convenient for cleaning.

[0076] In a possible implementation manner, the dust cup structure further includes a cup cover 500. The cup cover 500 is covered on one end of the dust cup body 100 facing away from the gas-dust separation component 300, and one end of the support sleeve facing away from the gas-dust separation component 300 abuts against the cup cover 500.

[0077] In this way, the cup cover 500 can simultaneously open and close the first dust collection cavity 110 and the second dust collection cavity 410. It can be understood that when the user operates the cup cover 500 once, the first dust collection cavity 110 and the second dust collection cavity 410 can be opened simultaneously. When the dust cup structure needs to be cleaned, opening the cup cover 500 can realize the simultaneous cleaning of liquid impurities and solid impurities, further improving the cleaning efficiency.

[0078] In other possible implementations, the dust cup body 100 has an air inlet 120 that is connected to the first dust collecting chamber 110 , and the air inlet 120 is located between the gas-liquid separation component 200 and the cup cover 500 .

[0079] The dust cup body 100 has an air outlet 130 , which is connected to the end of the gas-dust separation component 300 facing away from the gas-liquid separation component 200 .

[0080] In this way, the gas mixed with liquid impurities and solid impurities is sucked into the first dust collecting chamber 110 through the air inlet 120, and then passes through the separation action of the gas-liquid separation component 200 and the gas-dust separation component 300 in turn. The liquid impurities remain in the first dust collecting chamber 110, and the solid impurities remain in the second dust collecting chamber 410. Finally, the gas with separated liquid impurities and solid impurities is discharged from the dust cup main body 100 through the air outlet 130, and then enters the cleaning equipment.

[0081] It's understood that the motor assembly that provides suction power contains numerous electronic components, such as circuit boards, which are susceptible to short circuits and other malfunctions when exposed to liquid. Separating the liquid and solid impurities from the gas can reduce the likelihood of motor assembly failure within the cleaning device.

[0082] In one possible implementation, the cup cover 500 has a first connecting portion 510, and the dust cup body 100 has a second connecting portion 140, and the first connecting portion 510 and the second connecting portion 140 are detachably connected.

[0083] In a specific implementation, one of the first connecting portion 510 and the second connecting portion 140 is an external thread, and the other is an internal thread matching the external thread. Figure 1 As shown, the first connection portion 510 is an internal thread and the second connection portion 140 is an external thread. Of course, in other possible implementations, the first connection portion 510 may be an external thread and the second connection portion 140 may be an internal thread, which is not limited here.

[0084] In this way, the cup cover 500 and the dust cup body 100 are detachably connected through the first connecting portion 510 and the second connecting portion 140, which facilitates the opening and closing of the cup cover 500. The use of the internal thread and the external thread has a simple structure, convenient operation, and low manufacturing cost, thereby facilitating user operation.

[0085] In other specific implementations, the gas-liquid separation component 200 includes a centrifugal fan 210 and a power fan 220 coaxially connected to the centrifugal fan 210 . The power fan 220 drives the centrifugal fan 210 to rotate. The power fan 220 is located between the centrifugal fan 210 and the gas-dust separation component 300 .

[0086] In this way, when the gas-liquid separation component 200 is working, the gas sucked into the dust cup main body 100 is blown towards the power fan 220. The rotation of the power fan 220 drives the centrifugal fan 210 to rotate. The centrifugal fan 210 generates a centrifugal force to separate the liquid impurities in the gas. By using the flow of the gas to generate a centrifugal force, the energy of the gas flow can be fully utilized, improving the energy utilization rate.

[0087] In a possible implementation, referring to Figure 1 and Figure 2 as shown, the gas-liquid separation component 200 further includes a support frame 230. The support frame 230 abuts against the inner side wall of the dust cup main body 100. The support frame 230 is arranged above the centrifugal fan 210. The power fan 220 is coaxially inserted into the centrifugal fan 210 through the support frame 230.

[0088] In this way, the support frame 230 provides an installation position for the power fan 220 and the centrifugal fan 210, making the rotation of the power fan 220 and the centrifugal fan 210 more stable.

[0089] In a possible implementation, the power fan 220 has a first insertion part 221, and the centrifugal fan 210 has a second insertion part 211. One of the first insertion part 221 and the second insertion part 211 is inserted into the other.

[0090] In a specific implementation, at least one insertion block 2111 is provided on one of the first insertion part 221 and the second insertion part 211, and a slot 2211 corresponding to the insertion block 2111 is provided on the other. As Figure 2 shown, the first insertion part 221 has a slot 2211, and the insertion block 2111 is correspondingly arranged on the second insertion part 211.

[0091] The power fan 220 and the centrifugal fan 210 are inserted through the first insertion part 221 and the second insertion part 211. The structure is simple, facilitating the installation of the power fan 220 and the centrifugal fan 210. When the insertion block 2111 is inserted into the slot 2211, the fixation of the first insertion part 221 and the second insertion part 211 can be achieved, facilitating the coaxial rotation of the power fan 220 and the centrifugal fan 210.

[0092] In other possible implementations, the support frame 230 has a spiral air guiding channel 231. The air guiding channel 231 connects the centrifugal fan 210 and the power fan 220. In this way, the gas sucked into the dust cup main body 100 forms a spiral-flowing gas after passing through the spiral air guiding channel 231, and the spiral-flowing gas can drive the power fan 220 to rotate more conveniently and quickly.

[0093] In a possible implementation, referring to Figure 1 and Figure 3As shown, in order to make the rotation of the centrifugal fan 210 smoother, the gas-liquid separation assembly 200 further includes a first bearing 240. The first bearing 240 is sleeved on the support member 400 and is connected to the centrifugal fan 210. In addition, the first bearing 240 also provides a support point for the centrifugal fan 210, making the rotation of the centrifugal fan 210 more stable.

[0094] In order to improve the sealing performance at the first bearing 240, the gas-liquid separation assembly 200 further includes a bearing cover 250. The bearing cover 250 is sleeved on the support member 400 and abuts against the first bearing 240. In this way, on the one hand, the bearing cover 250 can play a role in positioning the first bearing 240, and on the other hand, it also has the functions of dust prevention and sealing, effectively preventing impurities from entering the inside of the first bearing 240 and affecting the operation of the first bearing 240.

[0095] In other possible implementation manners, the gas-liquid separation assembly 200 further includes a second bearing 260 and a mounting bracket 270. The mounting bracket 270 is arranged at the end of the power fan 220 facing away from the centrifugal fan 210. The mounting bracket 270 is connected to the support frame 230, and the second bearing 260 is arranged on the mounting bracket 270.

[0096] In this way, the power fan 220 is rotationally connected to the mounting bracket 270 through the second bearing 260, which can make the rotation of the power fan 220 smoother. In addition, the second bearing 260 also provides a support point for the power fan 220, making the rotation of the power fan 220 more stable.

[0097] In one possible implementation manner, a plurality of positioning grooves 271 are axially arranged on the mounting bracket 270, and a plurality of positioning blocks 232 corresponding to the positioning grooves 271 are arranged on the support frame 230. The positioning blocks 232 are inserted into the corresponding positioning grooves 271. It can realize the coaxial fixation and rotation of the mounting bracket 270 and the support frame 230. In addition, it is convenient for the installation and positioning of the mounting bracket 270.

[0098] In one possible implementation manner, a plurality of guide grooves 212 are formed on the side wall of the centrifugal fan 210. Each guide groove 212 is inclined, and the inclination directions of all the guide grooves 212 are the same. The inclination direction of each guide groove 212 is the same as the direction of the power fan 220, which is convenient for the centrifugal fan 210 to generate centrifugal force and then throw out the liquid impurities through the guide grooves 212.

[0099] In one possible implementation manner, refer to Figure 4 and Figure 5As shown, there is a gap 600 between the end face of the centrifugal fan 210 facing the support frame 230 and the support frame 230. The support frame 230 is a fixed structure relative to the rotatable centrifugal fan 210 and the power fan 220. The centrifugal fan 210 is rotatable, and the gap 600 between the end face of the centrifugal fan 210 facing the support frame 230 and the support frame 230 can reduce the wear between the centrifugal fan 210 and the support frame 230.

[0100] However, the gas-liquid separation component 200 is arranged inside the dust cup structure. Gas-dust separation and gas-liquid separation need to be carried out inside the dust cup structure. The gas-liquid separation component 200 will be in a gas mixed with liquid impurities and solid impurities during operation. Therefore, referring to Figure 4 As shown, there is at least one blocking portion 700 on the end face of the centrifugal fan 210 facing the support frame 230. The blocking portion 700 is configured to prevent water vapor from entering the rotating shaft of the centrifugal fan 210 through the gap 600.

[0101] In this way, the centrifugal fan 210 rotates around its rotating shaft. The blocking portion 700 prevents water vapor from entering the rotating shaft of the centrifugal fan 210 through the gap 600, which can ensure the normal operation of the centrifugal fan 210 and extend the service life of the centrifugal fan 210.

[0102] Continue to refer to Figure 4 and Figure 5 As shown, in order to further block water vapor from passing through the gap 600, referring to Figure 4 As shown, the number of the blocking portions 700 is multiple, and the multiple blocking portions 700 are evenly spaced along the circumferential direction of the end face of the centrifugal fan 210 facing the power fan 220. The even spacing of the blocking portions 700 can improve the efficiency of the blocking portions 700 to prevent water vapor from entering the inside of the rotating shaft of the centrifugal fan 210.

[0103] During specific implementation, the blocking portion 700 is inclined, and the inclination direction of each blocking portion 700 is opposite to the rotation direction of the centrifugal fan 210. When the centrifugal fan 210 is rotating, the inclined blocking portion 700 can form a centrifugal force to further block water vapor from passing through the gap 600.

[0104] The present application also provides a cleaning device, including a device main body and the above-mentioned dust cup structure. The dust cup structure is connected to the device main body. The specific structure of the dust cup structure has been explained above and will not be elaborated here. For the cleaning device provided with the above-mentioned dust cup structure, after the gas mixed with liquid impurities and solid impurities is sucked into the cleaning device, the liquid impurities and solid impurities can be separated, the separation effect is good, and the liquid impurities and solid impurities can be stored separately, thereby facilitating the user to clean and reducing the workload of the user.

[0105] The dust cup structure and cleaning device provided by the embodiments of the present application include a device main body and a dust cup structure.
