Description

Technical Field

[0001] This utility model belongs to the field of cleaning equipment technology, and specifically relates to a cleaning device. Background Technology

[0002] As the demand for wireless and portable technology drives innovation in handheld vacuum cleaners, traditional products face challenges due to their small dustbin capacity, the risk of secondary pollution from emptying, and the need for frequent maintenance. To address this, dust collection base stations have emerged. Their core technology utilizes a pneumatic transmission system to automatically extract dust and dirt, combined with a closed-loop multi-stage filtration system to prevent pollution spread, and integrates charging and intelligent sensing modules to improve battery life and user experience.

[0003] According to application number 202310651769.9, a cleaning device and its self-cleaning method are disclosed. This technology discloses that "the cleaning device includes a vacuum cleaner and a base station. The cleaning device has a vacuuming mode when the vacuum cleaner is used alone and a self-cleaning and self-dust collection mode when the vacuum cleaner is placed on the base station. The power source for both the vacuuming mode and the self-cleaning and self-dust collection modes is a fan assembly. The self-cleaning method includes the following steps: the vacuum cleaner is placed on the base station, the air duct is switched from a vacuuming air duct to a blowing air duct, and the fan assembly automatically starts to enter the self-cleaning and self-dust collection mode." It has the technical effect that "the vacuuming mode and the self-cleaning and self-dust collection modes use the same power source, which simplifies the structure, reduces the weight of the equipment, realizes the self-cleaning of the filter assembly and the dust cup body, and the self-cleaning step runs through the entire self-cleaning and self-dust collection process, resulting in better self-cleaning and self-dust collection effects."

[0004] However, this device relies on the bidirectional airflow capability of the filter components for vacuuming and self-cleaning operations. Therefore, it is compatible with structural types that support bidirectional airflow, such as HEPA filters, sponge / foam filters, and metal mesh filters. While multi-cone filters have high filtration efficiency and long service life, in this self-cleaning mode, if multi-cone filters are used, the dense arrangement of cones and large space occupation can clog the air blowing channel, thus affecting the self-cleaning effect. Therefore, the compatibility of this device needs to be improved.

[0005] To address the aforementioned problems, this application proposes a cleaning device. Utility Model Content

[0006] To address the aforementioned problems in the existing technology, this utility model provides a cleaning device that eliminates the need to consider the filter density in a vacuum cleaner.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cleaning device, including a vacuum cleaner and a base station. The vacuum cleaner includes a body, a fan assembly and a dust cup, a built-in filter assembly in the dust cup, and an openable lid at the bottom of the dust cup. The base station includes a main body, an internal dust bag, and a connecting pipe communicating with the dust bag on one side. A switching channel is provided on one side of the main body. When the main body is installed on the base station, the connecting pipe connects with the switching channel, and the fan assembly rotates under the action of the pushing assembly to communicate with the switching channel. The lid opens under the action of the releasing assembly to communicate with the dust bag. The negative pressure generated by the fan assembly draws the dust and dirt remaining inside the dust cup into the dust bag, thereby completing the self-cleaning of the cleaning device.

[0008] As a preferred technical solution of this utility model, the pushing component includes an arc-shaped toothed plate fixed to the outer shell of the fan component and an active toothed plate meshing with it. The bottom of the active toothed plate is integrally formed with a support base. The upper end of the support base is provided with a return spring that abuts against each other between it and the body. The top of the body is integrally formed with a trigger rod that cooperates with the support base. When the vacuum cleaner is connected to the base station, the trigger rod pushes the active toothed plate to mesh with the arc-shaped toothed plate, thereby rotating the fan component to communicate with the switching channel. The switching channel includes a dust collection connector and a dust collection channel formed in the body.

[0009] As a preferred technical solution of this utility model, the release component includes a card seat disposed on the cup lid away from the hinge end and a card plate that is engaged with the card seat by a card spring and hinged to the outside of the machine body. After the cup lid is opened, the dust cup and the dust bag are connected through a connecting cylinder located at the upper end of the body. The inner side of the connecting cylinder is provided with a protrusion for releasing the card plate.

[0010] As a preferred embodiment of this utility model, an air cavity is formed within the main body, the dust bag is placed inside the air cavity, and the connecting pipe is connected to the dust bag through the air cavity.

[0011] As a preferred embodiment of this utility model, the connecting pipe is provided with a secondary filter at the connection point of the air chamber.

[0012] As a preferred embodiment of this utility model, the filter assembly is a multi-cone filter body.

[0013] Compared with the prior art, the beneficial effects of this utility model are: self-cleaning is achieved by negative pressure suction, and the airflow does not need to pass through the filter component to enter the dust cup during the self-cleaning process, so there will be no blockage of the negative pressure channel. It can be compatible with traditional HEPA filters and more efficient multi-cone filters. The residual dust is directly introduced into the base station dust bag through directional negative pressure, while taking into account the high efficiency filtration and long life of multi-cone filters.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example

[0028] Please see Figure 1-10 This utility model provides the following technical solution: A cleaning device, including a vacuum cleaner 1 and a base station 2. The vacuum cleaner 1 includes a body 11, a fan assembly 12 and a dust cup 13, the dust cup 13 has a built-in filter assembly 131, and an openable cup lid 132 at the bottom of the dust cup 13. The base station 2 includes a body 21, and a dust bag 22 is provided inside the body 21. When the vacuum cleaner 1 is working alone, the cup lid 132 is closed, and the fan assembly 12 is connected to the filter assembly 131 through an air inlet 113. Figure 7 As shown, when the fan assembly 12 is started, the airflow enters the dust cup 13 from the air inlet pipe 111 and passes through the filter assembly 131. Under the action of the filter assembly 131, the dust is concentrated in the dust cup 13, and the airflow is discharged outward from the exhaust port 115, thus achieving the purpose of dust collection.

[0029] Furthermore, a connecting pipe 23 communicating with the dust bag 22 is provided on one side of the main body 21. The upper end of the connecting pipe 23 is open and equipped with a protective net. A switching channel 14 is provided on one side of the body 11. When the body 11 is installed on the main body 21, the upper end of the connecting pipe 23 is connected to the switching channel 14. At the same time, the fan assembly 12 rotates under the action of the pushing assembly 4 to communicate with the switching channel 14. The cup cover 132 opens under the action of the releasing assembly 5 and opens under its own weight and the negative pressure of the fan assembly 12 to communicate with the dust bag 22. The negative pressure generated by the fan assembly 12 sucks the dust and dirt remaining inside the dust cup 13 into the dust bag 22, thereby completing the self-cleaning of the cleaning equipment.

[0030] Furthermore, the upper end of the main body 21 is provided with a connecting cylinder 24, and an air cavity 211 communicating with it is located below the connecting cylinder 24. The dust bag 22 is located in the air cavity 211. The air cavity 211 provides sufficient space for airflow to pass through the dust bag 22. The upper end of the connecting cylinder 24 matches the bottom opening of the dust cup 13, and the lower end matches the collection port of the dust bag 22. The overall shape is wider at the top and narrower at the bottom. The upper inner side of the connecting cylinder 24 forms a rotation space for opening the cup lid 132.

[0031] Furthermore, the driving component 4 includes an arc-shaped toothed plate 41 fixed to the outer shell of the fan component 12 and an active toothed plate 42 meshing with it. A support base 421 is integrally formed at the bottom of the active toothed plate 42. A return spring 43 abuts against the upper end of the support base 421 and the body 11. A trigger rod 44, which cooperates with the support base 421, is integrally formed at the top of the body 21. When the vacuum cleaner 1 connects to the base station 2, the trigger rod 44 pushes the active toothed plate 42 upwards and meshes with the arc-shaped toothed plate 41, thereby rotating the fan component 12 to communicate with the switching channel 14, i.e., switching to the self-cleaning mode of the cleaning equipment. In this embodiment, as shown... Figure 8 As shown, when the fan assembly 12 is started, the airflow enters the dust cup 13 from the air inlet pipe 111. The connecting tube 24 guides the dust in the dust cup 13 into the dust bag 22. Then the airflow flows through the air chamber 211, the connecting pipe 23 and the switching channel 14, and finally exits from the exhaust port 115, realizing the self-cleaning of the cleaning equipment.

[0032] The switching channel 14 includes a dust collection connector 112 and a dust collection channel 114 formed in the body 11 and interconnected. When the body 11 is connected to the main body 21, the dust collection connector 112 is connected to the upper end of the connecting pipe 23. The two can be connected by plugging or snapping. The dust collection channel 114 is connected to the suction port of the fan assembly 12. The connection between the dust collection channel 114 and the fan assembly 12 is an arc-shaped surface.

[0033] Furthermore, the release component 5 includes a retainer 51 disposed on the cup lid 132 away from the hinge end and a retainer plate 52 hinged to the outside of the body 11. One hinged end of the retainer plate 52 is provided with a retaining spring 53 that abuts against each other between it and the body 11. The other end of the retainer plate 52 is engaged with the retainer 51 through the retaining spring 53 when the cup lid 132 is closed. After the cup lid 132 is opened, the dust cup 13 and the dust bag 22 are connected through a connecting cylinder 24. The inner side of the connecting cylinder 24 is provided with a protrusion 54 for releasing the retainer plate 52. In this embodiment, when the body 11 is docked with the main body 21, the protrusion 54 automatically pushes the retainer plate 52 to disengage from the retainer 51 and compresses the retaining spring 53, thereby connecting the dust cup 13 with the connecting cylinder 24, which facilitates the collection of dust into the dust bag 22.

[0034] Furthermore, the dust bag 22 is detachably connected to the air chamber 211. The upper end of the air chamber 211 has a socket that matches the upper end of the cardboard of the dust bag 22. A circular through-hole is provided in the cardboard for the dust bag 22 to connect to the bottom of the connecting cylinder 24. A sealing ring is provided between the air chamber 211 and the collection port of the dust bag 22, and the sealing ring is connected to the air chamber 211. One side of the air chamber 211 has an opening and is connected to a side cover plate 26 via a snap-fit ​​mechanism 3. The snap-fit ​​mechanism 3 includes a spring that is mounted on the side cover... The upper end of the plate 26 has a locking block 31 and a locking groove 32 in the body 21 that engages with the locking block 31, as well as an insert block 33 fixed to the bottom of the side cover plate 26 and a slot 34 in the body 21 that engages with the insert block 33. In this embodiment, the locking block 31 is connected to a lever extending to the outside of the side cover plate 26. When the side cover plate 26 is closed, the locking block 31 is pushed down by the lever to disengage from the locking groove 32, thereby removing the side cover plate 26 for the replacement and maintenance of the dust bag 22 and the secondary filter 25.

[0035] Furthermore, the connecting pipe 23 is connected to the dust bag 22 through the air chamber 211. The connecting pipe 23 is provided with a secondary filter 25 at the connection point of the air chamber 211. The secondary filter 25 is connected to the bottom of the air chamber 211 by a side plug-in method to prevent finer dust from entering the connecting pipe 23. The side plug-in method also has the advantages of being easy to clean and replace.

[0036] Furthermore, the filter assembly 131 is a multi-cone filter, so the airflow in this negative pressure channel does not need to pass through the filter assembly 131 to enter the dust cup 13, and there will be no blockage of the negative pressure channel. Therefore, a multi-cone filter with better filtration effect than traditional HEPA filters can be used.

[0037] Furthermore, such as Figure 3 and Figure 4 As shown, the body 11 has a socket 7 near the internal battery pack 116. The body 21 has a protruding plug 6 that connects to the socket 7. The socket 7 connects to the battery pack 116, and the plug 6 connects to the power source. When the vacuum cleaner 1 is connected to the base station 2, the battery pack 116 in the vacuum cleaner 1 can be charged through the connection of the plug 6 and the socket 7.

[0038] Working principle and usage process of this utility model:

[0039] The cleaning equipment has two modes: vacuuming and self-cleaning.

[0040] Vacuuming mode: In this mode, vacuum cleaner 1 works independently. The air intake pipe 111 is connected to the floor brush (not shown in the figure). The fan assembly 12 is turned on by the switch on vacuum cleaner 1. The battery pack 116 powers the fan assembly 12. Under the action of the floor brush and the air intake pipe 111, dust and debris are sucked into the dust cup 13. The filter assembly 131 filters the dust and debris. The airflow passes through the filter assembly 131 and the air intake 113 and is discharged from the exhaust port 115, thus completing the vacuuming operation.

[0041] Self-cleaning mode: In this mode, the vacuum cleaner 1 is docked to the base station 2. During the docking process, the air inlet of the fan assembly 12 is rotated from the air inlet 113 to connect with the switching channel 14 under the action of the pushing component 4. At the same time, the cup cover 132 is released during the docking process through the release component 5. The cup cover 132 rotates downward at the bottom of the dust cup 13 under its own gravity and the gravity of the dust. After the fan assembly 12 is started, the airflow flows along the air inlet pipe 111, dust cup 13, connecting cylinder 24, dust bag 22, air chamber 211, connecting pipe 23, and switching channel 14, and then is discharged from the exhaust port 115. Under the action of negative pressure, the dust in the dust cup 13 is introduced into the dust bag 22 through the connecting cylinder 24, thereby completing the self-cleaning operation.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
