Description

Technical Field

[0001] The present application relates to the field of dust collection technology, and in particular to a dust cup assembly, a dust cleaner and a cleaning system. Background Art

[0002] The dust cup of the vacuum cleaner adopts dust separation technology, which can effectively prevent the filter of the vacuum cleaner from being blocked and prevent the suction power of the vacuum cleaner from dropping rapidly and affecting the user experience. In the related art, the dust cup includes two dust collecting chambers. The primary dust collecting chamber separates and settles the main garbage, and the unseparated dust enters the secondary dust collecting chamber and then settles in the secondary dust collecting chamber. The garbage is collected in the two dust collecting chambers respectively, and it is troublesome to clean the dust in the two dust collecting chambers. Summary of the invention

[0003] In view of this, the embodiments of the present application hope to provide a dust cup assembly, a vacuum cleaner and a cleaning system to facilitate cleaning of dust debris in the dust cup.

[0004] In order to achieve the above-mentioned purpose, the technical solution of the embodiment of the present application is implemented as follows:

[0005] The present application discloses a dust cup assembly, including:

[0006] The dust cup is formed with a cyclone chamber, an ash storage chamber, an air inlet and an air outlet, wherein the cyclone chamber is located above the ash storage chamber and is communicated with the ash storage chamber, and the air inlet is formed on the circumferential surface of the dust cup and is communicated with the cyclone chamber;

[0007] A separation cone, wherein the separation cone is arranged in the cyclone chamber, a separation chamber is formed in the separation cone, the separation chamber is connected with the air outlet and the ash storage chamber, and an air flow inlet is formed on the outer peripheral surface of the separation cone, the air flow inlet is connected with the separation chamber and the cyclone chamber;

[0008] The separation element is connected to the cavity wall of the cyclone cavity.

[0009] The embodiment of the present application discloses a dust cup assembly, a dust collector and a cleaning system. On the one hand, a cyclone chamber and an ash storage chamber are formed in the dust cup. The cyclone chamber is located above the ash storage chamber and is connected to the ash storage chamber. The air inlet is connected to the ash storage chamber. In this way, the airflow enters the cyclone chamber through the air inlet. Part of the dust in the airflow collides with the chamber wall of the cyclone chamber under the action of centrifugal force and can directly fall into the ash storage chamber to complete the initial separation of the airflow. A separation chamber is formed in the separation cone, and an airflow inlet is formed on the outer peripheral surface of the separation cone. In this way, the airflow in the cyclone chamber that has undergone initial separation can enter the separation chamber through the airflow inlet to separate it again, so that the dust with a smaller particle size in the airflow collides with the chamber wall of the separation chamber under the action of centrifugal force, and then falls into the ash storage chamber under the action of gravity to complete the secondary separation of the airflow. Finally, the clean gas generated can be blown out of the dust cup from the air outlet to complete the separation of dust and gas. The dust after the initial separation and the secondary separation are collected in the ash storage chamber, which is convenient for the subsequent unified cleaning of the dust cup. On the other hand, by providing a separation piece, it is possible to effectively prevent the cyclonic airflow in the ash storage chamber from rolling up the dust, so that the dust is confined in the ash storage chamber, further improving the cyclonic separation effect.

DETAILED DESCRIPTION

[0017] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the present application and should not be regarded as an improper limitation on the present application.

[0018] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The descriptions of "first", "second", etc. in the embodiments of the present application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly including at least one feature. In the description of the embodiments of the present application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically limited.

[0019] In the related art, the secondary dust collecting chamber is arranged at the center of the primary dust collecting chamber, the primary dust collecting chamber is connected to the air inlet, and the secondary dust collecting chamber is connected to the air outlet. The airflow carrying dust from the air inlet flows through the primary dust collecting chamber and the secondary dust collecting chamber in turn. After dust removal in the primary dust collecting chamber and the secondary dust collecting chamber in turn, the clean airflow is discharged from the air outlet.

[0020] The present application provides a dust cup assembly. Figures 1 to 5 The dust cup assembly 1 includes a dust cup 11, a separation cone 12 and a separation member 13. The dust cup 11 is formed with a cyclone chamber 11a, an ash storage chamber 11b, an air inlet 11c and an air outlet 11d. The cyclone chamber 11a is located above the ash storage chamber 11b and communicates with the ash storage chamber 11b. The air inlet 11c is formed on the circumferential surface of the dust cup 11 and communicates with the cyclone chamber 11a. Specifically, the air inlet 11c is located on the circumferential surface of the dust cup 11 corresponding to the cyclone chamber 11a.

[0021] The separation cone 12 is disposed in the cyclone chamber 11a, and a separation chamber 12a is formed in the separation cone 12, and the separation chamber 12a is connected to the air outlet 11d and the ash storage chamber 11b, and an air flow inlet 12b is formed on the outer peripheral surface of the separation cone 12, and the air flow inlet 12b is connected to the separation chamber 12a and the cyclone chamber 11a. The separation member 13 is connected to the cavity wall of the cyclone chamber 11a.

[0022] The dust cup assembly 1 provided in the present application, on the one hand, has a cyclone chamber 11a and an ash storage chamber 11b formed in the dust cup 11, the cyclone chamber 11a is located above the ash storage chamber 11b and is connected to the ash storage chamber 11b, and the air inlet 11c is connected to the ash storage chamber 11b, so that the airflow enters the cyclone chamber 11a through the air inlet 11c, and part of the dust in the airflow collides with the cavity wall of the cyclone chamber 11a under the action of centrifugal force, and can directly fall into the ash storage chamber 11b, completing the initial separation of the airflow. By forming a separation chamber 12a in the separation cone 12 and forming an airflow inlet 12b on the outer peripheral surface of the separation cone 12, the airflow in the cyclone chamber 11a that has undergone the initial separation can enter the separation chamber 12a through the airflow inlet 12b to be separated again, so that the dust particles with smaller particle sizes in the airflow collide with the chamber wall of the separation chamber 12a under the action of centrifugal force, and then fall into the ash storage chamber 11b under the action of gravity, completing the secondary separation of the airflow, and finally the clean gas generated can be blown out of the dust cup 11 from the air outlet 11d to complete the separation of dust and gas, and the dust particles after the initial separation and the secondary separation are collected in the ash storage chamber 11b, which is convenient for the subsequent unified cleaning of the dust cup 11. On the other hand, by setting the separation member 13, it is possible to effectively avoid the situation where the airflow flowing in the cyclone in the ash storage chamber 11b rolls up the dust particles, so that the dust particles are confined in the ash storage chamber 11b, further improving the cyclone separation effect.

[0023] It should be noted that the cyclone chamber 11a is a space for cyclone separation, and the ash storage chamber 11b is a space for dust storage.

[0024] In one embodiment, please refer to Figure 1 and Figure 5 , a gap 1a is formed between the separator 13 and the outer peripheral surface of the separation cone 12. That is to say, the separator 13 is located in the cyclone chamber 11a. Exemplarily, one end of the separator 13 in the width direction is connected to the cavity wall of the cyclone chamber 11a, and the other end of the separator 13 in the width direction extends toward the separation cone 12, and is spaced apart from the outer peripheral surface of the separation cone 12 to form a gap 1a. The gap 1a connects the cyclone chamber 11a and the ash storage chamber 11b. In this way, the dust in the airflow of the cyclone chamber 11a can fall directly from the gap 1a into the ash storage chamber 11b under the action of centrifugal force and gravity, completing the separation of dust and air.

[0025] Exemplarily, in one embodiment, the shape of the dust cup 11 is not limited, for example, it can be a hollow cylinder or cone, etc.

[0026] In one embodiment, please refer to Figure 1 and Figure 5 , the air inlet 11c is located above the separator 13. Exemplarily, the air inlet 11c can be set on the side of the separator 13 away from the ash storage chamber 11b. The separator 13 is a spiral plate extending downward from the upper spiral around the outer circumference of the separation cone 12. The spiral plate has one end close to the air inlet 11c as the head end, and the other end of the spiral plate as the tail end. The spiral plate, the cavity wall of the cyclone cavity 11a and the outer circumferential surface of the separation cone 12 together define a spiral channel, and the end of the spiral channel is connected to the ash storage chamber 11b. In this way, on the one hand, the dust with a large mass carried in the airflow entering from the air inlet 11c falls along the spiral plate into the ash storage chamber 11b, with high separation efficiency and good cyclone separation effect; on the other hand, compared with other forms of channels, the spiral channel can provide a larger channel area under the same space occupation, thereby increasing the flow rate and flux of the airflow, and improving the dust collection efficiency.

[0027] For example, in one embodiment, please refer to Figure 1 The lower end of the spiral plate is formed with through holes 13a that penetrate through both end surfaces in the thickness direction. Exemplarily, the through holes 13a can be formed at the end of the spiral channel, and the through holes 13a connect the spiral channel and the ash storage chamber 11b, so that the airflow entering from the air inlet 11c can flow downward through the spiral channel, and when it flows to the end of the spiral plate, it can flow from the through holes 13a into the ash storage chamber 11b, so as to enhance the fluidity of the airflow, avoid the situation where the airflow is blocked to form a vortex, and facilitate the storage of dust.

[0028] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 5The dust cup assembly 1 includes an air guide plate 14 located in the cyclone chamber 11a. The air guide plate 14 extends upward from the head end of the separation member 13 along the surrounding separation cone 12 from the lower spiral. The outer peripheral surface of the separation cone 12, the cavity wall of the cyclone chamber 11a and the air guide plate 14 define an air guide channel. Here, the air guide plate 14 extends upward from the lower spiral, and the air guide channel formed is also in a spiral form, so that the flow resistance of the airflow can be reduced, the noise is small, and the user experience is good. After the airflow passes through the air inlet 11c, a primary cyclone is formed in the air guide channel. Since the air guide plate 14 is arranged around the separation cone 12 from the head end of the separation element 13, that is, the outlet of the air guide channel is connected to the inlet of the spiral channel, at this time, the airflow entering from the air inlet 11c flows downward through the guide spiral of the air guide channel to form a secondary cyclone in the spiral channel. The airflow entering the spiral channel enters the separation chamber 12a from the air flow inlet 12b on the outer peripheral surface of the separation cone 12. Dust particles with larger particle sizes contact the wall of the air guide channel, such as the cavity wall of the cyclone cavity 11a, the air guide plate 14, etc., and then fall through the spiral channel, or fall through the gap 1a between the spiral plate and the outer peripheral surface of the separation cone 12. In this way, the dust can be further pressed toward the spiral channel, so that the dust can be better stored in the ash storage cavity 11b.

[0029] In one embodiment, the distance between the head end of the air guide plate 14 and the head end of the separator 13 is between 0 mm and 5 mm. For example, the distance between the head end of the air guide plate 14 and the head end of the separator 13 can be 0 mm, 1 mm, 2 mm, 3 mm, 4 mm or 5 mm, etc., that is, the head end of the air guide plate 14 can abut against the head end of the separator 13 or have a small gap. In this way, by setting a distance of appropriate size, the dust can be better pressed toward the spiral channel, and the dust and gas separation effect is good. .

[0030] In one embodiment, please refer to Figure 1 and Figure 2 , the air guide plate 14 is connected to the outer peripheral surface of the separation cone 12. Exemplarily, one end of the air guide plate 14 is connected to the outer peripheral surface of the separation cone 12, and the other end of the air guide plate 14 extends away from the separation cone 12, and finally abuts against the cavity wall of the cyclone cavity 11a, so that after the airflow enters the air inlet 11c, it can be guided to flow between the upper surface of the separation element 13 and the lower surface of the air guide plate 14, thereby improving the flowability of the gas.

[0031] In one embodiment, please refer to Figure 2The dust cup assembly 1 includes a guide portion 15, which is located at the air inlet 11c so that the airflow at the air inlet 11c flows into the air guide channel along the tangent direction of the separation cone 12 at the air inlet 11c. Exemplarily, the shape of the guide portion 15 is not limited, for example, it can be a curved plate, which is arranged at the air guide channel near the air inlet 11c. A part of the curved surface of the guide portion 15 is tangent to the part of the separation cone 12 at the air inlet 11c, and another part of the curved surface of the guide portion 15 receives the air inlet 11c. In this way, on the one hand, the airflow entering from the air inlet 11c will change its flow direction when flowing through the surface of the guide portion 15, so that it flows into the air guide channel along the tangent direction. In this way, the cavity wall of the cyclone cavity 11a and the outer peripheral surface of the separation cone 12 can reduce the resistance of the airflow, reduce the wind loss, and facilitate the airflow to flow spirally downward after entering the air inlet 11c; on the other hand, the guide portion 15 is arranged at the air inlet 11c to block the airflow and prevent the airflow from flowing spirally upward.

[0032] In one embodiment, please refer to Figure 1 The dust cup assembly 1 includes an air filter plate 16 disposed in the ash storage chamber 11b. Exemplarily, the location of the air filter plate 16 is not limited. For example, the air filter plate 16 can be connected to the end of the separator 13. The thickness direction of the air filter plate 16 is perpendicular to the up-down direction. In other words, the air filter plate 16 extends in the up-down direction. The air filter plate 16 is formed with a plurality of through holes 16a that pass through both end surfaces in the thickness direction. In this way, on the one hand, the airflow in the ash storage chamber 11b can flow through the through holes 16a to reduce the situation where the airflow accumulates in the corners to form vortices; on the other hand, the air filter plate 16 extends in the up-down direction, which can also block dust from flowing with the airflow to a certain extent, thereby preventing dust from rising.

[0033] Exemplarily, in one embodiment, the air filter plate 16 and the separator 13 may be integrally formed, so that the connection strength between the air filter plate 16 and the separator 13 may be improved.

[0034] In one embodiment, the portion of the separator 13 close to the separation cone 12 is bent downward to form a shielding portion 13b. In this way, the dust can be further pressed into the ash storage chamber 11b to prevent the dust from entering the cyclone chamber 11a from the ash storage chamber 11b, and the ash storage effect is good. Here, since the shielding portion 13b is arranged on the separator 13, the shielding portion 13b can also be arranged in a spiral downward.

[0035] Exemplarily, in one embodiment, a first sawtooth is formed below the shielding portion, so that the first sawtooth can hook foreign objects such as hair and cotton wool that are easy to entangle and difficult to handle, so as to prevent these foreign objects from entering the cyclone chamber 11a from the ash storage chamber 11b, thereby improving the cleaning effect.

[0036] Exemplarily, in one embodiment, a second serration is formed at the lower end of the separation cone 12, so that the second serration can hook foreign objects such as hair and cotton wool that are easy to entangle and difficult to handle, so as to prevent these foreign objects from rising from the ash storage chamber 11b into the separation chamber 12a, thereby improving the cleaning effect.

[0037] In one embodiment, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 , the air outlet 11d is formed on the upper surface of the dust cup 11. Exemplarily, the air outlet 11d is formed at the center of the upper surface of the dust cup 11, forming a central upward suction force, so that the central suction force forms a cyclone separation effect, so as to separate the airflow entering from the air inlet 11c, store the dust in the airflow in the dust storage chamber 11b, reduce the dust content of the airflow flowing out of the air outlet 11d, and make the discharged airflow cleaner.

[0038] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 5 , openings are formed at both ends of the separation chamber 12a in the up-down direction. In other words, the separation chamber 12a is penetrated in the up-down direction. The lower end opening of the separation chamber 12a is connected to the ash storage chamber 11b, and the upper end opening of the separation chamber 12a is connected to the air outlet 11d. In this way, when the airflow is cyclone-separated in the cyclone chamber 11a and the separation chamber 12a, the dust can fall into the ash storage chamber 11b from the gap 1a and the lower end opening respectively under the action of centrifugal force and gravity, while the cleaner airflow can be drawn out from the air outlet 11d to the outside of the dust cup 11 through the upper end opening of the separation cone 12, thereby completing the separation of dust and air.

[0039] Illustratively, in one embodiment, the axes of the upper opening and the lower opening of the separation chamber 12a may coincide with each other, thereby reducing the flow resistance of the outflowing airflow and increasing the exhaust rate.

[0040] In one embodiment, please refer to Figures 1 to 3 The dust cup 11 includes a cover door 111 and a cup body 112 having an ash storage chamber 11b. An ash discharge port 112a communicating with the ash storage chamber 11b is formed at the bottom of the cup body 112. The cover door 111 can selectively open or close the ash discharge port 112a. Exemplarily, the dust cup assembly 1 includes a first locking member 17 disposed on the cup body 112 and a second locking member 18 disposed on the cover door 111. The first locking member 17 and the second locking member 18 cooperate to selectively lock or unlock the cover door 111. In this way, when the dust cup assembly 1 is collecting dust, the first locking member 17 and the second locking member 18 cooperate to lock the cover door 111 to close the ash discharge port 112a. In this way, the dust in the ash storage chamber 11b can be prevented from leaking out of the dust cup 11 through the ash discharge port 112a.

[0041] For example, in one embodiment, please refer to Figures 1 to 3 The cover door 111 is rotatably connected to the cup body 112. For example, the cover door 111 includes a cover body 1111 and a rotating portion 1112. The second locking member 18 is disposed on the cover body 1111. One end of the rotating portion 1112 is connected to the cover body 1111, and the other end of the rotating portion 1112 extends toward the direction close to the cup body 112. In some embodiments, the dust cup 11 includes a rotating shaft 113 and a fixing member 114, the fixing member 114 is fixedly arranged on the cup body 112, the fixing member 114 is formed with a mounting groove 114a, the rotating part 1112 is arranged in the mounting groove 114a, a first rotating hole is formed on the groove wall of the mounting groove 114a, a second rotating hole is formed on the rotating part 1112, the rotating shaft 113 passes through the first rotating hole and the second rotating hole, so that the cover door 111 can be rotated by means of the rotating shaft 113 and the rotating hole. On the one hand, the number of parts required for the rotation of the rotating shaft 113 and the rotating hole is small, easy to maintain, and high reliability; on the other hand, the rotation of the rotating shaft 113 and the rotating hole does not require the use of complex hydraulic and pneumatic systems, low maintenance cost, and easy to implement.

[0042] For example, in one embodiment, please refer to Figure 2 and Figure 3 The number of the first locking members 17 and the number of the second locking members 18 are not limited. For example, there can be two of them. The two first locking members 17 are arranged on the cup body 112 at intervals along the axial extension direction of the rotating shaft 113, and the two second locking members 18 are arranged on the cover body 1111 at intervals along the axial extension direction of the rotating shaft 113. Each first locking member 17 is in contact with and cooperates with a second locking member 18 to improve the connection strength between the cover door 111 and the dust cup 11, so that the cover door 111 is not easy to be flipped open during the dust collection operation of the dust cup assembly 1.

[0043] In one embodiment, the first locking member 17 and the second locking member 18 are magnetically matched. In this way, the connection between the two can be achieved by magnetic attraction without external force, which is convenient to use, simple and easy to operate, and has high stability.

[0044] Exemplarily, in one embodiment, the magnetic attraction cooperation of the first locking member 17 and the second locking member 18 includes but is not limited to the following forms: For example, the first locking member 17 and the second locking member 18 may both be permanent magnets. For another example, one of the first locking member 17 and the second locking member 18 is a permanent magnet, and the other of the first locking member 17 and the second locking member 18 is a ferromagnetic material such as iron, nickel or chromium. For another example, the first locking member 17 and the second locking member 18 may both be electromagnets. For another example, one of the first locking member 17 and the second locking member 18 is an electromagnet, and the other of the first locking member 17 and the second locking member 18 is a material such as iron, nickel or chromium. For another example, one of the first locking member 17 and the second locking member 18 is an electromagnet, and the other of the first locking member 17 and the second locking member 18 is a permanent magnet.

[0045] Another aspect of the present application embodiment provides a vacuum cleaner 100, see Figure 4 and Figure 5 , including the dust cup assembly 1 in any one of the above embodiments.

[0046] The vacuum cleaner 100 may be a handheld vacuum cleaner 100. First, the handheld vacuum cleaner 100 is small in size and light in weight; second, it has wide applicability, and the handheld vacuum cleaner 100 can clean various cleaning occasions such as baseboards, carpets, sofas, and mattresses.

[0047] Another aspect of the present application embodiment provides a cleaning system 1000, see Figure 4 and Figure 5 , comprising a base station 200 and the dust collector 100 in the above embodiment. A dust collecting bin 201a is formed in the base station 200, and the dust collecting bin 201a is used to collect dust in the dust storage cavity 11b.

[0048] The cleaning system 1000 provided in the embodiment of the present application can insert the dust cup 11 into the dust collecting bin 201a when it is necessary to clean the dust in the ash storage chamber 11b, and then open the ash discharge port 112a. In this way, the dust in the ash storage chamber 11b can enter the dust collecting bin 201a through the ash discharge port 112a to clean the ash storage chamber 11b, thereby providing a good storage space for the dust cup 11 for the next cleaning of the surface to be cleaned.

[0049] It should be noted that the surface to be cleaned includes but is not limited to the floor or the tabletop and the like.

[0050] For example, in one embodiment, please refer to Figure 4 and Figure 5The base station 200 includes a base body 201 and an unlocking member. The base body 201 is formed with a dust collecting bin 201a. At least part of the unlocking member is located in the dust collecting bin 201a. When the dust cup 11 enters the dust collecting bin 201a, the unlocking member drives the first locking member 17 and the second locking member 18 to separate to unlock the cover door 111. In this way, when it is necessary to clean the dust in the ash storage chamber 11b, the dust cup 11 can be inserted into the dust collecting bin 201a. The unlocking member can drive the first locking member 17 and the second locking member 18 to separate to unlock the cover door 111, so that the ash discharge port 112a is automatically opened, and the degree of automation is high.

[0051] For example, in one embodiment, please refer to Figure 4 The upper surface of the dust bin 201a is formed with a take-in and take-out port 201b connected to the dust bin 201a, and the dust cup 11 enters and exits the dust bin 201a in the up-down direction through the take-in and take-out port 201b. In this way, on the one hand, the vacuum cleaner 100 and the base station 200 are plugged in the up-down direction, which can reduce the floor space of the cleaning system 1000, improve the space utilization rate, and also facilitate the user to perform plug-in or pull-out operations; on the other hand, by forming the take-in and take-out port 201b on the upper surface of the dust bin 201a and forming the ash discharge port 112a at the bottom of the cup body 112, the dust in the ash storage cavity 11b can fall into the dust bin 201a located below it by its own gravity, and cleaning is relatively simple; on the other hand, after the unlocking member drives the first locking member 17 and the second locking member 18 to separate and unlock the cover door 111, the cover door 111 can rotate around the rotating shaft 113 by its own gravity in the direction away from the cup body 112 to open the ash discharge port 112a.

[0052] For example, in one embodiment, please refer to Figures 1 to 3 The vacuum cleaner 100 includes a shell 2 connected to the outer peripheral surface of the cup body 112, the shell 2 and the outer peripheral surface of the cup body 112 jointly define a receiving chamber 2a, the receiving chamber 2a is formed with a communication port 2b toward the cover door 111, and a notch 2c communicating with the receiving chamber 2a is formed on the peripheral side of the shell 2, a portion of the first locking member 17 is arranged in the receiving chamber 2a, the first locking member 17 cooperates with the second locking member 18 through the communication port 2b, and the portion of the first locking member 17 passing through the notch 2c is used to connect with the unlocking member For example, taking the dust cup 11 being inserted downward into the dust collecting bin 201a as an example, in the process of the dust cup 11 entering the dust collecting bin 201a, the part of the first locking member 17 passing through the slot 2c is contacted and moved by the unlocking member, thereby driving the part of the first locking member 17 located in the accommodating chamber 2a to slide upward, and then the part of the first locking member 17 located at the connecting port 2b enters the accommodating chamber 2a, the first locking member 17 is separated from the second locking member 18, the cover door 111 is unlocked, and the ash discharge port 112a is opened.
