Description

Technical Field

[0001] The present invention relates to the technical field of household cleaning equipment, and in particular to a vacuum cleaner cleaning system and a control method. Background Art

[0002] As an important tool for modern household cleaning, the design and function of vacuum cleaners have been continuously optimized and developed in recent years. Traditional vacuum cleaners are generally maintained by manual cleaning. Users need to regularly remove filters or replace dust bags, and manually dump or discard the adsorbed dust. However, this cleaning method has certain limitations. It is not only cumbersome to operate, but also easy to cause dust overflow and pollution, and it also increases the workload of users.

[0003] With the advancement of technology, some vacuum cleaner systems with automatic cleaning functions have gradually appeared on the market, usually through the linkage between the vacuum cleaner base station and the vacuum cleaner to complete the cleaning of the filter. In the existing technology, most systems use a fan drive method to transfer the dust in the filter to the dust bag of the base station by using the suction force of the airflow through the air duct. However, this type of technical solution still has obvious defects and shortcomings in actual use:

[0004] Existing cleaning systems mostly rely on negative pressure airflow to directly suck the dust in the filter. However, for stubborn dust attached to the inner wall and folds of the filter, it is difficult to completely clean it with a single airflow suction, resulting in a lot of dust residue, which affects the cleaning effect. Some existing technologies do not have a dedicated structure designed for filter cleaning, such as a rotating device or an auxiliary cleaning mechanism. The cleaning process is only performed through the airflow in the duct. This design cannot effectively clean tightly attached dust particles, which limits the cleaning efficiency. In the existing technology, some vacuum cleaner cleaning systems use a single air duct design and do not have the ability to switch independent airflow channels for different cleaning processes. Users need to manually adjust the airflow path or connecting components to switch the cleaning state. This method is prone to cumbersome operation and may even cause dust overflow. The existing technology usually requires the fan to run for a long time to maintain the negative pressure required during the cleaning process. However, since the air duct design in the system is not fully optimized, it often requires higher power consumption to achieve basic cleaning needs. This high-energy consumption design not only increases the cost of use, but also affects the long-term operating reliability of the equipment. Many cleaning systems are overly versatility-oriented in design, resulting in complex internal structures, especially the air duct layout and the connection design between the cleaning chamber and the dust bag chamber are not intuitive enough, which increases the difficulty of production and user use.

[0005] In summary, the current vacuum cleaner cleaning system has certain defects in cleaning effect, airflow path design, operation convenience, energy consumption, etc. These problems directly affect the actual use effect of the cleaning system and become the main bottleneck for the further development of the vacuum cleaner cleaning system. A vacuum cleaner cleaning system is urgently needed to solve the above problems. Summary of the invention

[0006] The object of the present invention is to provide a vacuum cleaner cleaning system and a control method to solve the above-mentioned defects of the prior art.

[0007] In one aspect, the present invention provides a vacuum cleaner cleaning system, comprising:

[0008] A vacuum cleaner and a vacuum cleaner base station; the vacuum cleaner comprises a first fan, a first air duct, and a dust cup cavity; the first fan is installed inside the vacuum cleaner and connected to the first air duct; the vacuum cleaner base station comprises a second air duct, a third air duct, a cleaning cavity and a dust bag cavity; the first air duct is connected to the dust cup cavity, and the first air duct is substantially a cavity between the first fan and the dust cup cavity; the second air duct is connected to the first air duct, the third air duct is connected to the other end of the second air duct, the other end of the third air duct is connected to the dust bag cavity, and the cleaning cavity is connected to the dust bag cavity.

[0009] The technical solution provides a vacuum cleaner cleaning system, including a vacuum cleaner and a vacuum cleaner base station. The vacuum cleaner is connected to the vacuum cleaner base station through a first air duct and a dust cup cavity, and the first fan is used to provide suction; the base station is provided with multiple air ducts (second and third air ducts), a cleaning cavity and a dust bag cavity, forming an air flow path for completing the transfer and cleaning of dust from the vacuum cleaner to the base station. By establishing a reasonable air flow path between the vacuum cleaner and the base station, automatic transfer and centralized cleaning of dust are realized, which effectively reduces the user's operating burden, while ensuring the efficiency and convenience of the cleaning process.

[0010] The cleaning chamber further comprises a filter; the filter is detachably mounted in the cleaning chamber through a slot provided on the vacuum cleaner base station, and the filter can be rotated in the cleaning chamber by an external force.

[0011] The technical solution further defines the filter and slot structure set in the cleaning chamber. The filter can be rotated in the cleaning chamber by external force to clean the internal dust. The filter can be detachably installed through the slot, which is convenient for user operation and maintenance; by setting the slot and the rotating design of the filter, the filter can be flexibly disassembled and efficiently cleaned, while avoiding dust spillage, improving the convenience of use and cleaning effect.

[0012] A toggle valve is also provided at the connection point between the cleaning cavity and the dust bag cavity, and the toggle valve can control whether the cleaning cavity and the dust bag cavity are connected.

[0013] This technical solution adds a toggle valve between the cleaning chamber and the dust bag chamber. The toggle valve can control the on and off state between the two to ensure that dust transmission during the cleaning process is controlled. At the same time, the toggle valve controls the airflow path to make the airflow more concentrated, thereby improving cleaning efficiency.

[0014] The cleaning chamber further comprises a driving device, which is fixedly mounted on the inner wall of the cleaning chamber and is engaged with the filter to drive the filter to rotate.

[0015] This technical solution adds a driving device in the cleaning chamber to drive the filter to rotate. The driving device is connected to the filter by a snap-on connection to ensure the stability of rotation and the cleaning effect, reducing the user's workload. The automatic rotation design of the driving device can more thoroughly clean the dust on the inner wall and folds of the filter, improve the cleaning effect, and reduce the user's manual rotation operational burden.

[0016] The cleaning chamber further comprises a paddle, which is arranged on the inner wall of the cleaning chamber perpendicular to the filter, and is used to paddle the folds on the filter when the filter rotates.

[0017] The technical solution further defines a paddle structure arranged on the inner wall of the cleaning chamber, which is used to clean the dust on the filter folds when the filter rotates. It can effectively enhance the cleaning force on the filter folds, making the cleaning process more thorough, while avoiding dust accumulation that affects equipment performance.

[0018] A second fan is arranged in the dust bag cavity, and the second fan is used to create negative pressure in the dust bag cavity.

[0019] This technical solution is another path of the present invention. When the second fan is used, the second air duct, the third air duct, the cleaning chamber and the dust bag chamber form a whole. The second fan is used to form a negative pressure inside the whole. Compared with the original technical solution, this technical solution does not involve the first air duct and does not use the first fan, and its cleaning effect is better.

[0020] It also includes a fourth air duct, the fourth air duct connecting the dust cup cavity and the dust bag cavity;

[0021] The toggle valve connects the cleaning chamber and the dust bag chamber while blocking the fourth air duct. Conversely, the toggle valve blocks the cleaning chamber and the dust bag chamber while connecting the dust cup chamber and the dust bag chamber.

[0022] This technical solution adds a fourth air duct to connect the dust cup cavity and the dust bag cavity. The toggle valve is used to control the connectivity of the fourth air duct, thereby switching between different airflow paths. The combination of the fourth air duct and the toggle valve further optimizes the selection of airflow paths, ensuring that the cleaning process can run efficiently in different states while preventing dust leakage.

[0023] A first valve is provided in the first air duct, and the first valve is used to close the connection between the first air duct and the second air duct while the first air duct connects the first fan and the dust cup cavity, or to close the connection between the first air duct and the dust cup cavity when the second air duct is connected to the first air duct.

[0024] The technical solution defines a first valve arranged in the first air duct, and the first valve is used to switch the connectivity state of the first air duct to ensure the rationality of the air duct connection under different cleaning modes. The design of the first valve can accurately control the air duct passage according to different cleaning modes to avoid air flow path conflicts, thereby optimizing the air flow distribution and improving the stability of equipment operation and cleaning efficiency.

[0025] In a second aspect, the present invention provides a control method for a vacuum cleaner cleaning system, comprising the following steps:

[0026] Step 1: When the filter needs to be cleaned, the cleaning process is started;

[0027] Step 2: Install the filter into the cleaning chamber through the card slot to ensure stable installation;

[0028] Step 3: Turn the toggle valve to connect the cleaning chamber and the dust bag chamber to form an air flow channel;

[0029] Step 4: Control the first valve to close the connection between the first air duct and the dust cup chamber, and start the first fan to generate negative pressure;

[0030] Step 5: Manually rotate the filter in the cleaning chamber to remove attached dust;

[0031] Step 6: After cleaning is completed, turn off the first fan and terminate the cleaning process.

[0032] The technical solution includes steps such as filter installation, valve switching, fan start-up and filter cleaning. It details the system's workflow, simplifies the user's operating procedures, ensures an efficient and orderly cleaning process, and avoids dust spillage and incorrect switching of airflow paths.

[0033] The steps also include starting a driving device, which drives the filter to rotate. The beneficial effect is that by introducing automatic control of the driving device during the cleaning process, the efficiency and thoroughness of the filter cleaning are improved, while the complexity of user operations is reduced, thereby improving the overall user experience.

[0039] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] A first aspect of the present invention discloses a vacuum cleaner cleaning system. Figures 1 to 3 Schematic diagram of a vacuum cleaner cleaning system according to an embodiment of the present invention. Figures 1 to 3 As shown, the vacuum cleaner cleaning system comprises:

[0041] Vacuum cleaner 100, vacuum cleaner base station 200;

[0042] The vacuum cleaner 100 includes a first fan 101, a first air duct 102, and a dust cup chamber 104;

[0043] The first fan 101 is installed inside the vacuum cleaner 100 and connected to the first air duct 102;

[0044] The vacuum cleaner base station 200 includes a second air duct 201, a third air duct 202, a cleaning chamber 204 and a dust bag chamber 205;

[0045] The first air duct 102 is connected to the dust cup cavity 104, and the first air duct 102 is substantially a cavity between the first fan 101 and the dust cup cavity 104;

[0046] The second air duct 201 is connected to the first air duct 102 , the third air duct 202 is connected to the other end of the second air duct 201 , the other end of the third air duct 202 is connected to the dust bag cavity 205 , and the cleaning cavity 204 is connected to the dust bag cavity 205 .

[0047] The cleaning chamber 204 further includes a filter;

[0048] The filter is detachably installed in the cleaning chamber 204 through a slot provided on the vacuum cleaner base station 200 , and the filter can be rotated in the cleaning chamber 204 by an external force.

[0049] A toggle valve 206 is further provided at the connection point between the cleaning chamber 204 and the dust bag chamber 205 . The toggle valve 206 can control whether the cleaning chamber 204 and the dust bag chamber 205 are connected.

[0050] The cleaning chamber 204 further includes a driving device 207 , which is fixedly mounted on the inner wall of the cleaning chamber 204 and engages with the filter to drive the filter to rotate.

[0051] The cleaning chamber 204 further includes a paddle 208 , which is disposed on the inner wall of the cleaning chamber 204 and is perpendicular to the filter. The paddle 208 is used to paddle the folds on the filter when the filter rotates.

[0052] A second fan 210 is disposed in the dust bag cavity 205 , and the second fan 210 is used to create negative pressure in the dust bag cavity 205 .

[0053] It also includes a fourth air duct 209, and the fourth air duct 209 connects the dust cup cavity 104 and the dust bag cavity 205;

[0054] The toggle valve 206 connects the cleaning chamber 204 and the dust bag chamber 205 while blocking the fourth air duct 209 . Conversely, the toggle valve 206 blocks the cleaning chamber 204 and the dust bag chamber 205 while connecting the dust cup chamber 104 and the dust bag chamber 205 .

[0055] A first valve 103 is provided in the first air duct 102. The first valve 103 is used to connect the first air duct 102 to the first fan 101 and the dust cup chamber 104 while closing the connection between the first air duct 102 and the second air duct 201, or to close the connection between the first air duct 102 and the dust cup chamber 104 when the second air duct 201 is connected to the first air duct 102.

[0056] In one embodiment, the first valve 103 is in a state of isolating the first air duct 102 and the dust cup chamber 104, ensuring that the suction force generated by the first fan 101 will not directly act on the first air duct 102 and the vacuum cleaner body, converging the airflow path, and the toggle valve 206 is adjusted to a state of connecting the dust cup chamber 104 and the dust bag chamber 205, and closing the cleaning chamber. Since the cleaning chamber is connected to the outside world, the internal negative pressure of the air flow dispersion will be insufficient, and the airflow in the dust cup chamber 104 can enter the dust bag chamber 205, thereby completing the cleaning and transfer of dust; the first fan 101 creates a negative pressure in the dust bag chamber 205 through the second air duct 201 and the third air duct 202, and when the negative pressure is In use, the airflow enters the dust cup cavity 104 from the grid vent at the upper part of the dust cup cavity 104; the grid is designed as an air supply channel; when the airflow enters the dust cup cavity 104, driven by the negative pressure, the high-speed airflow has a scouring effect on the surface and interior of the filter, especially at the folds of the filter, and the dust particles are peeled off by the kinetic energy of the airflow; the peeled dust is carried by the airflow, enters the dust bag cavity 205 through the toggle valve 206, and is collected in the dust bag in the dust bag cavity 205; the toggle valve 206 is used to achieve effective control of the airflow path to prevent dust from leaking out during the cleaning process, while ensuring that the airflow connection state between the dust cup cavity 104 and the dust bag cavity 205 is stable.

[0057] During the entire cleaning process, the first fan 101 always keeps running to provide a stable negative pressure drive. The second air duct 201 and the third air duct 202 connect the dust bag chamber 205 with the first fan 101, forming a stable negative pressure transmission path, ensuring that the airflow can continue to flow from the dust cup chamber 104 into the dust bag chamber 205, thereby maintaining the efficient operation of the cleaning process. The design of the grid vents prevents large particles of dust from blocking the airflow path, while ensuring the smooth distribution of the airflow, and evenly applies a flushing effect to each part of the filter to achieve the purpose of thoroughly cleaning the filter. The opening and closing states of the first valve 103 and the toggle valve 206 are linked to the airflow path to ensure the efficiency and reliability of the cleaning process. The dust cup chamber 104 completes the effective removal of dust on the surface of the filter through the combined effect of pressure difference and high-speed airflow, and at the same time, the dust is safely transmitted to the dust bag chamber 205 through the toggle valve 206. The air path of this design is simple and reasonable, the operation state is stable, and the filter cleaning process can be completed efficiently.

[0058] In another embodiment, the first valve 103 is adjusted to a state of isolating the first air duct 102 from the dust cup chamber 104, ensuring that the suction force of the first fan 101 will not directly act on the dust cup chamber 104, but is used to drive the airflow of other air ducts, and the toggle valve 206 is adjusted to a state of isolating the dust cup chamber 104 from the dust bag chamber 205, thereby forming an independent airflow path, so that the cleaning chamber 204 is connected with the dust bag chamber 205; in this state, after the first fan 101 is started, negative pressure is generated through the second air duct 201 and the third air duct 202, and the airflow path forms the following closed loop: the first air duct 102 is connected with the second air duct 201 and the third air duct 202, and the third air duct 202 is connected with the dust bag chamber 205 and the cleaning chamber 204. Due to the negative pressure, external air enters the cleaning chamber 204 from the opening between the cleaning chamber 204 and the outside, and cleans the filter in the cleaning chamber 204, and the high-speed airflow surges into the cleaning chamber 204. When entering, the filter surface is flushed in the cleaning chamber 204, and the dust attached to the filter surface and folds is peeled off. The peeled dust is carried by the airflow, enters the third air duct 202 through the cleaning chamber 204, and finally enters the dust bag chamber 205 and is captured by the dust bag, thereby cleaning the filter in the cleaning chamber 204. In order to further improve the cleaning effect, the filter in this embodiment is connected to the driving device 207 in the cleaning chamber 204 through a clamping structure. After the driving device 207 is started, it drives the filter to rotate in the cleaning chamber 204. The rotation of the filter makes its surface evenly flushed by the airflow, especially at the folds of the filter. The rotating action can enhance the peeling of dust. In addition, the inner wall of the cleaning chamber 204 is provided with a paddle 208, which cooperates with the surface of the filter. When the filter rotates, the folds of the filter are paddled, further improving the cleaning efficiency of the filter surface. The paddle 208 is designed to fit closely with the surface of the filter, and its position and shape are optimized to ensure that the dust at the folds of the filter can be efficiently cleaned without affecting the smooth airflow.

[0059] The entire cleaning process is powered by the first fan 101. Each air duct drives the airflow through negative pressure to complete the cleaning of the filter in the cleaning chamber 204. During the cleaning process, external air flows in through the opening of the cleaning chamber 204, and a stable airflow is formed under the action of negative pressure, ensuring that the filter in the cleaning chamber 204 is fully flushed and rotated for cleaning. After the dust is carried into the dust bag chamber 205 by the airflow, it is captured by the dust bag to prevent dust from overflowing and airflow path blockage. This embodiment optimizes the air duct design and cooperates with the drive device 207 and the paddle 208 to make the filter cleaning more thorough, especially the cleaning effect of the folded parts is significantly enhanced. The entire cleaning process is efficient and stable, and is suitable for scenes with complex cleaning requirements.

[0060] In another embodiment, the first valve 103 is adjusted to a state of isolating the first air duct 102 from the dust cup chamber 104, and the toggle valve 206 is adjusted to a state of isolating the dust cup chamber 104 from the cleaning chamber 204, ensuring that the airflow path acts on the negative pressure path between the cleaning chamber 204 and the dust bag chamber 205. At this time, the second fan 210 is started to generate negative pressure in the cleaning chamber 204 and the dust bag chamber 205 through the second air duct 201 and the third air duct 202; due to the negative pressure, the airflow enters from the cleaning chamber 204 and the external opening, and forms a high-speed airflow in the cleaning chamber 204 to clean the filter. Under the scouring action of the airflow, the dust and particles attached to the surface of the filter inside the cleaning chamber 204 are stripped off by the airflow and carried into the dust bag chamber 205. After the dust enters the dust bag cavity 205 through the third air duct 202, it is captured by the dust bag, achieving effective collection. In order to enhance the cleaning effect, in this embodiment, the filter is connected to the driving device 207 in the cleaning cavity 204 through the card slot. The driving device 207 is started during the cleaning process to drive the filter to rotate at a certain speed. The rotating action exposes the filter surface to the high-speed airflow evenly, thereby more thoroughly removing the dust and attached particles on the surface. In addition, the inner wall of the cleaning cavity 204 is provided with a paddle 208, which paddles the pleated part of the filter when it rotates, thereby strengthening the cleaning force of the pleated part. The paddle 208 matches the design of the filter, and can effectively remove stubborn dust during the cleaning process, further improving the cleaning effect. Compared with the previous embodiment, this embodiment forms a smaller negative pressure cavity between the cleaning cavity 204, the dust bag cavity 205, the second air duct 201, and the third air duct 202 through the start-up of the second fan 210 and the partition design of the paddle valve 206. The reduction in the cavity volume significantly increases the negative pressure strength and enhances the scouring force of the airflow, so the cleaning effect on the filter is better, especially the cleaning of stubborn dirt is more thorough. In addition, the strong negative pressure environment allows the dust to be carried to the dust bag cavity 205 faster by the airflow, thereby improving the cleaning efficiency. This embodiment uses an optimized negative pressure cavity design to form a more efficient cleaning environment in the cleaning cavity 204. The scouring effect of the high-speed airflow combined with the rotation of the filter and the mechanical assistance of the paddle 208 significantly improves the cleaning efficiency and thoroughness of the filter in the cleaning cavity 204, and is suitable for scenes with higher requirements for cleaning effects. The entire process runs stably, the air path is designed reasonably, the cleaning power is significantly enhanced, and the dust treatment is more efficient and reliable.

[0061] A second aspect of the present invention discloses a control method for a vacuum cleaner cleaning system, comprising:

[0062] Step 1: When the filter needs to be cleaned, the cleaning process is started;

[0063] Step 2: Install the filter into the cleaning chamber 204 through the card slot to ensure stable installation;

[0064] Step 3: Toggle the toggle valve 206 to connect the cleaning chamber 204 and the dust bag chamber 205 to form an air flow channel;

[0065] Step 4: Control the first valve 103 to close the connection between the first air duct 102 and the dust cup chamber 104, and start the first fan 101 to generate negative pressure;

[0066] Step 5: Manually rotate the filter in the cleaning chamber to remove attached dust;

[0067] Step 6: After cleaning is completed, turn off the first fan 101 and terminate the cleaning process.

[0068] The step 5 also includes starting a driving device 207, which drives the filter to rotate.

[0069] In a specific embodiment, a control method for a vacuum cleaner cleaning system comprises the following steps:

[0070] Check the status of the vacuum cleaner base station to ensure that there is no obstruction in the cleaning chamber 204 and that the filter has been correctly installed in the cleaning chamber 204 through the card slot on the base station.

[0071] The toggle valve 206 is adjusted to a state where the cleaning chamber 204 and the dust bag chamber 205 are connected.

[0072] The first valve 103 is adjusted to a state of isolating the first air duct 102 and the dust cup chamber 104 to ensure that the suction force of the first fan 101 is dedicated to the cleaning chamber 204 .

[0073] The first fan 101 is started, and forms negative pressure in the dust bag chamber 205 and the cleaning chamber 204 through the second and third air ducts 201 and 202. Since the cleaning chamber 204 is connected to the outside through an opening, the outside air flows into the cleaning chamber 204 under the negative pressure.

[0074] After the airflow enters the cleaning chamber 204, it directly acts on the filter in the cleaning chamber 204, and the dust particles attached to the filter surface and folds are peeled off by the high-speed flushing of the airflow, and the dust is carried into the dust bag chamber 205 by turning the valve 206 and captured by the dust bag.

[0075] The driving device 207 is started, and the driving device 207 drives the filter to rotate in the cleaning chamber 204 through the clamping structure. The rotation of the filter makes its surface evenly exposed to the airflow, further enhancing the dust stripping effect.

[0076] While the filter is rotating, the paddle 208 disposed on the inner wall of the cleaning chamber 204 will cooperate with the pleated portion of the filter, and accelerate the removal of stubborn dust at the pleats through mechanical plucking action, thereby ensuring deep cleaning of the filter.

[0077] After the cleaning time reaches a preset value or the cleaning effect reaches a set requirement, the first fan 101 and the driving device 207 are turned off.

[0078] The toggle valve 206 is adjusted to a state where the cleaning chamber 204 and the dust bag chamber 205 are separated to prevent dust from flowing back during subsequent operations.

[0079] Remove the filter manually or automatically and check the cleaning result.

[0080] The present invention realizes efficient cleaning of the filter through the design of the first fan 101, the second fan 210 and the multi-duct system, combined with the airflow path switching function of the toggle valve. The high-speed airflow under the negative pressure can act evenly on the filter surface, especially the airflow path introduced through the external opening of the cleaning chamber 204, avoiding the decrease in cleaning effect caused by airflow dispersion. With the rotation of the filter and the mechanical toggle action of the paddle, the present invention can effectively peel off the stubborn dust at the folds of the filter to ensure the comprehensiveness and thoroughness of cleaning. Through the flexible adjustment of the first valve 103 and the toggle valve 206, different cleaning modes can be quickly switched to meet different cleaning needs. For example, by adjusting the valve, the cleaning chamber 204 or the dust cup chamber 104 can be selected for cleaning. The whole process does not require complicated manual operation. The user only needs to simply set the valve state and start the fan to complete the cleaning task, which improves the convenience of use; the multi-duct design (including the first duct, the second duct and the third duct) of the present invention and the connecting structure between the dust cup chamber, the cleaning chamber and the dust bag chamber are optimized to form a closed and efficient airflow path. In different cleaning modes, the connection state of the airflow path can be flexibly switched to avoid the problem of airflow backflow or dust leakage; the present invention is particularly designed to enhance the cleaning effect of the filter. By setting a driving device 207 to drive the filter to rotate, and combining with the paddle 208 in the cleaning chamber 204, deep cleaning of the filter surface and pleated parts is achieved. The rotating filter can evenly peel off dust under the action of high-speed airflow, and the mechanical prying action of the paddle further cleans the dust particles that are difficult to remove from the filter pleats, significantly improving the cleaning effect.
