Description

Technical Field

[0001] This invention relates to the field of electrical equipment technology, specifically to an air purifier, a control method and device for the air purifier, and a computer device. Background Technology

[0002] Currently, filter-type air purifiers purify the air by physically adsorbing small particulate harmful substances such as pollen through filters. However, because the filters adsorb substances indiscriminately, larger foreign objects (such as hair and debris) are adsorbed on the filter surface during the purification process. If users do not regularly clean and maintain the filters, impurities will accumulate on the filter surface after prolonged use, leading to a reduction in the air intake area and a decrease in purification efficiency. Moreover, the long-term accumulation of foreign objects on the filter surface can even cause bacterial growth, which can be harmful to human health. Summary of the Invention

[0003] In view of this, the present invention provides an air purifier, an air purifier control method, an apparatus, and a computer device to solve the problem that the air purifier filter needs to be manually cleaned.

[0004] In a first aspect, embodiments of the present invention provide an air purifier, including a filter, an air duct, a dust collection device, a dust collection device, and a fan; the filter is used to filter air flowing through the air purifier; the air duct has a first state in a purification mode and a second state in a dust removal mode; in the first state, the air passage area of ​​the air duct is a first region, and in the second state, the air passage area of ​​the air duct is a second region; the dust collection device includes a suction port and a transfer port, the suction port facing the filter and used to collect adsorbents on the filter; the transfer port is connected to a first end of the second region; the dust collection device is connected to a second end of the second region, and the fan is used to provide power for air to flow within the air purifier; in the purification mode, under the action of the fan, air passes sequentially through the filter and the first region of the air duct in the air purifier; in the dust removal mode, under the action of the fan, air passes sequentially through the filter, the dust collection device, the second region of the air duct, and the dust collection device in the air purifier.

[0005] The air purifier provided in this embodiment of the invention, in purification mode, allows air to pass sequentially through a filter and a first area of ​​the air duct under the action of a fan. After a certain purification time, some foreign objects (such as hair, debris, particles, dust, etc.) are adsorbed onto the surface of the filter during the purification process. In dust removal mode, under the action of a fan, air passes sequentially through a filter, a vacuuming device, a second area of ​​the air duct, and a dust collection device. Because the foreign objects on the filter are only slightly adhered to its surface, when the fan is working, a certain suction force exists between the vacuuming device and the filter, causing the foreign objects on the filter surface to be adsorbed into the vacuuming device and then directly reach the dust collection device through the second area of ​​the air duct. In other words, the air purifier provided in this embodiment of the invention can automatically clean the foreign objects on the surface of the filter, solving the problem of the need for manual cleaning of air purifier filters.

[0006] In one alternative implementation, the first area of ​​the first region is larger than the second area of ​​the second region.

[0007] Understandably, with a smaller airflow area, the suction force generated between the dust collection device and the filter is greater under the same fan speed, thus allowing the filter to be cleaned more thoroughly.

[0008] In one alternative implementation, the duct includes a channel and blades, the blades being rotatably disposed around the channel. When there is no gap between two adjacent blades, the duct is in a second state; otherwise, the duct is in a first state.

[0009] This allows the air duct to have a first state under purification mode and a second state under dust removal mode.

[0010] In one alternative embodiment, the filter is rotatably mounted on the base of the air purifier; the vacuuming device is fixedly mounted on the base, and the vacuuming port can cover the filter.

[0011] This allows the dust collection device to adsorb dust from all 360° of the filter surface.

[0012] In one alternative embodiment, the air purifier further includes a connecting tube disposed between the second end of the vacuuming device and the first end of the second region.

[0013] This allows for a more rational design of air purifiers.

[0014] Secondly, embodiments of the present invention provide a control method for an air purifier. The air purifier includes a filter, an air duct, a dust collection device, a dust collection device, and a fan. The filter is used to filter the air flowing through the air purifier. The air duct has a first state in a purification mode and a second state in a dust removal mode. In the first state, the air passage area of ​​the air duct is a first region, and in the second state, the air passage area of ​​the air duct is a second region. The dust collection device includes a suction port and a transfer port. The suction port faces the filter and is used to collect adsorbents on the filter. The transfer port is connected to a first end of the second region. The dust collection device is connected to a second end of the second region. The fan is used to provide power for the air to flow within the air purifier. In the purification mode, under the action of the fan, the air passes through the filter and the first region of the air duct in sequence within the air purifier. In the dust removal mode, under the action of the fan, the air passes through the filter, the dust collection device, the second region of the air duct, and the dust collection device in sequence within the air purifier. The control method for the air purifier includes: receiving a control command; when the control command is a dust removal command, issuing a first command that the air duct is in the second state to cause the air purifier to enter the dust removal mode.

[0015] The air purifier control method provided in this embodiment, upon receiving a dust removal command, issues a first instruction that the air duct is in a second state, thereby enabling the air purifier to enter dust removal mode. In dust removal mode, air passes sequentially through the filter, the suction device, the second area of ​​the air duct, and the dust collection device within the air purifier. Because foreign objects (such as hair, debris, particles, dust, etc.) adhere to the surface of the filter with relatively weak adhesion, when the fan is working, a certain suction force exists between the suction device and the filter. The foreign objects on the filter surface are adsorbed into the suction device and can then directly reach the dust collection device through the second area of ​​the air duct. In other words, the air purifier provided in this embodiment can automatically clean foreign objects from the surface of the filter, solving the problem of the need for manual cleaning of air purifier filters.

[0016] In one optional embodiment, the filter screen is rotatably mounted on the base of the air purifier; the dust collection device is fixedly mounted on the base, and the dust collection port can cover the filter screen; the control method of the air purifier further includes: when a dust removal command is received, issuing a second command for the filter screen to rotate on the base.

[0017] This allows the dust collection device to adsorb dust from all 360° of the filter surface.

[0018] In one optional implementation, after the air purifier enters the dust removal mode, the following steps are further included: obtaining the first running time of the air purifier in the dust removal mode; when the first running time reaches a preset first time threshold, issuing a third command to turn off the air purifier and issuing a prompt message that the dust collection device needs to be processed.

[0019] This allows for timely cleaning of the dust collection device.

[0020] In one optional implementation, the air purifier control method further includes the following steps: when the air purifier is running in purification mode, obtaining a second running time of the air purifier in purification mode; when the second running time reaches a preset second time threshold, issuing a dust removal command; or, when receiving an instruction to activate the dust removal mode, issuing a dust removal command.

[0021] This allows the system to automatically enter dust removal mode, or it can be activated according to the user's needs.

[0022] In one alternative implementation, the air purifier operating in purification mode includes: issuing a fourth instruction indicating that the air duct is in a first state when the air purifier is started or when a purification instruction is received, so as to cause the air purifier to enter purification mode.

[0023] This allows the air purifier to enter purification mode when it is turned on or when a purification command is received.

[0024] Thirdly, embodiments of the present invention also provide a control device for an air purifier. The air purifier includes a filter, an air duct, a dust collection device, a dust collection device, and a fan. The filter is used to filter the air flowing through the air purifier. The air duct has a first state in a purification mode and a second state in a dust removal mode. In the first state, the air passage area of ​​the air duct is a first region, and in the second state, the air passage area of ​​the air duct is a second region. The dust collection device includes a suction port and a transfer port. The suction port faces the filter and is used to collect adsorbed matter on the filter. The transfer port is connected to the first end of the second region. The dust collection device is connected to the second end of the second region. The air purifier is connected to a fan that provides the power for airflow within the purifier. In purification mode, the air passes sequentially through the filter and the first area of ​​the duct under the action of the fan. In dust removal mode, the air passes sequentially through the filter, the dust collection device, the second area of ​​the duct, and the dust collection device under the action of the fan. The air purifier's control device includes a control command receiving module and a mode adjustment module. The control command receiving module receives control commands. When a dust removal command is received, the mode adjustment module issues a first command indicating that the duct is in a second state, causing the air purifier to enter dust removal mode.

[0025] Fourthly, embodiments of the present invention also provide a computer device, including a memory and a processor, which are communicatively connected to each other. The memory stores computer instructions, and the processor executes the computer instructions to perform the control method of the air purifier described in the second aspect or any corresponding embodiment.

[0026] Fifthly, embodiments of the present invention also provide an air purifier, including the computer device of the fourth aspect.

[0027] In a sixth aspect, embodiments of the present invention also provide a computer-readable storage medium storing computer instructions, which are used to cause a computer to execute the control method of the air purifier described in the second aspect or any corresponding embodiment.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] This invention provides an air purifier, such as... Figure 1 As shown, the air purifier includes a filter 1, an air duct 2, a dust collection device 3, a dust collection device 4, and a fan 5. The filter 1 is used to filter the air flowing through the air purifier. The air duct 2 has a first state in purification mode and a second state in dust removal mode. In the first state, the air passage area of ​​the air duct 2 is the first region, and in the second state, the air passage area of ​​the air duct 2 is the second region. The dust collection device 3 includes a suction port and a transfer port. The suction port faces the filter 1 and is used to collect adsorbed matter on the filter 1. The transfer port is connected to the first end of the second region. The dust collection device 4 is connected to the second end of the second region. The fan 5 is used to provide the power for the air to flow inside the air purifier. In purification mode, under the action of the fan 5, the air passes through the filter 1 and the first region of the air duct 2 in sequence in the air purifier. In dust removal mode, under the action of the fan 5, the air passes through the filter 1, the dust collection device 3, the second region of the air duct 2, and the dust collection device 4 in sequence in the air purifier.

[0039] Specifically, the dust collection device 4 is made of HEPA mesh, which can block foreign objects such as hair, debris, particles, and dust, but does not obstruct airflow. For example, the dust collection device 4 can be a dust collection box.

[0040] Specifically, centrifugal fan blades are used in fan 5.

[0041] The air purifier provided in this embodiment of the invention, in purification mode, under the action of fan 5, air passes sequentially through the filter 1 and the first area of ​​the air duct 2. After a certain purification time, some foreign objects (such as hair, debris, particles, dust, etc.) are adsorbed on the surface of the filter 1 during the purification process. In dust removal mode, under the action of fan 5, air passes sequentially through the filter 1, the vacuuming device 3, the second area of ​​the air duct 2, and the dust collection device 4. Since the foreign objects on the filter 1 are attached to the surface of the filter 1 and the adhesion is relatively small, when the fan 5 is working, there is a certain suction force between the vacuuming device 3 and the filter 1. The foreign objects on the surface of the filter 1 are adsorbed into the vacuuming device 3, and then can directly reach the dust collection device 4 through the second area of ​​the air duct 2. In other words, the air purifier provided in this embodiment of the invention can automatically clean the foreign objects on the surface of the filter 1, solving the problem that the air purifier filter needs to be cleaned manually.

[0042] In one alternative implementation, the first area of ​​the first region is larger than the second area of ​​the second region. It is understood that with a smaller airflow area, under the same fan speed, the suction force generated between the dust collection device 3 and the filter 1 is greater, thereby allowing the filter 1 to be cleaned more thoroughly.

[0043] In one alternative embodiment, the air duct 2 includes a channel 7 and blades 8, the blades 8 being rotatably disposed around the channel 7. When there is no gap between two adjacent blades 8, the air duct 2 is in a second state; otherwise, the air duct 2 is in a first state. For example, ... Figure 2 As shown, in purification mode, the blades 8 are vertical, allowing airflow from all sides and the center, resulting in a large airflow area. In dust removal mode, all blades 8 rotate 90° and are horizontal, allowing airflow only in the center. That is, the four sides and the center constitute the first area, and the center constitutes the second area. It should be noted that the air duct 2 is not limited to this structure, and the number of blades 8 is not limited to the number shown in the diagram; any air duct 2 capable of allowing airflow from all sides and the center can be used.

[0044] Specifically, a blade 8 driving device is provided on the air duct 2, which drives the blade 8 to rotate so that the air duct 2 can switch between the first state and the second state.

[0045] In one alternative embodiment, the filter 1 is rotatably mounted on the base of the air purifier; the vacuuming device 3 is fixedly mounted on the base, and the suction port can cover the filter 1. This allows the vacuuming device 3 to adsorb dust from all 360° of the filter surface.

[0046] Specifically, such as Figure 1 As shown, the base at the bottom of the purifier has a rotatable device, and the filter screen 1 is mounted on the rotatable device; the vacuuming device 3 is the same height as the filter screen 1, fixedly mounted on the base, and cannot be rotated, and the vacuuming port of the vacuuming device 3 is aligned with the filter screen 1.

[0047] In one alternative embodiment, the air purifier further includes a connecting pipe 6 disposed between the second end of the vacuuming device 3 and the first end of the second region. This allows for a more rational structure of the air purifier.

[0048] According to an embodiment of the present invention, an embodiment of a control method for an air purifier is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0049] This embodiment provides a control method for an air purifier, which can be used in computer equipment. The air purifier includes a filter, an air duct, a dust collection device, a dust collection device, and a fan. The filter is used to filter the air flowing through the air purifier. The air duct has a first state in a purification mode and a second state in a dust removal mode. In the first state, the air passage area of ​​the air duct is a first region; in the second state, the air passage area of ​​the air duct is a second region. The dust collection device includes a suction port and a transfer port. The suction port faces the filter and is used to collect adsorbed matter on the filter. The transfer port is connected to a first end of the second region. The dust collection device is connected to a second end of the second region. The fan provides the power for air to flow within the air purifier. In purification mode, under the action of the fan, air passes sequentially through the filter and the first region of the air duct within the air purifier. In dust removal mode, under the action of the fan, air passes sequentially through the filter, the dust collection device, the second region of the air duct, and the dust collection device within the air purifier.

[0050] The air purifier control method of this invention includes the following steps:

[0051] When a dust removal command is received, a first instruction is issued that the air duct is in the second state, so that the air purifier enters the dust removal mode.

[0052] As described above, a blade drive device is installed on the air duct. This device drives the blades to rotate, causing the air duct to switch between a first state and a second state. It can be understood that a first command is sent to the blade drive device, and under its action, the air duct can enter the second state. For example, as... Figure 2 As shown, when the air duct is in the second state, only the middle part of the air duct can be ventilated.

[0053] The air purifier control method provided in this embodiment, upon receiving a dust removal command, issues a first instruction that the air duct is in a second state, thereby enabling the air purifier to enter dust removal mode. In dust removal mode, air passes sequentially through the filter, the suction device, the second area of ​​the air duct, and the dust collection device within the air purifier. Because foreign objects (such as hair, debris, particles, dust, etc.) adhere to the surface of the filter with relatively weak adhesion, when the fan is working, a certain suction force exists between the suction device and the filter. The foreign objects on the filter surface are adsorbed into the suction device and can then directly reach the dust collection device through the second area of ​​the air duct. In other words, the air purifier provided in this embodiment can automatically clean foreign objects from the surface of the filter, solving the problem of the need for manual cleaning of air purifier filters.

[0054] This embodiment provides a control method for an air purifier, which can be used in computer equipment. The air purifier includes a filter, an air duct, a dust collection device, a dust collection device, and a fan. The filter is used to filter the air flowing through the air purifier. The air duct has a first state in a purification mode and a second state in a dust removal mode. In the first state, the air passage area of ​​the air duct is a first region; in the second state, the air passage area of ​​the air duct is a second region, wherein the first area of ​​the first region is larger than the second area of ​​the second region. The dust collection device includes a suction port and a transfer port. The suction port faces the filter and is used to collect adsorbed matter on the filter. The transfer port is connected to a first end of the second region. The dust collection device is connected to a second end of the second region. The fan provides the power for air to flow within the air purifier. In purification mode, under the action of the fan, air passes sequentially through the filter and the first region of the air duct within the air purifier. In dust removal mode, under the action of the fan, air passes sequentially through the filter, the dust collection device, the second region of the air duct, and the dust collection device within the air purifier. The filter is rotatably mounted on the base of the air purifier; the vacuum cleaner is fixedly mounted on the base, and the vacuum port can cover the filter.

[0055] Figure 3 This is a flowchart of an air purifier control method according to an embodiment of the present invention, such as... Figure 3 As shown, the process includes the following steps:

[0056] Step S301: When a dust removal command is received, a first command is issued that the air duct is in the second state and a second command is issued that the filter screen rotates on the base, so that the air purifier enters the dust removal mode.

[0057] Understandably, in dust removal mode, when the filter rotates on the base, the filter surface can be adsorbed by the dust collection device from 360°.

[0058] Step S302: Obtain the first running time of the air purifier in dust removal mode.

[0059] Step S303: When the first running time reaches the preset first time threshold, issue a third command to shut down the air purifier and issue a prompt message that the dust collection device needs to be processed.

[0060] This is because when an air purifier runs in dust removal mode for a certain period of time, a lot of foreign objects (such as hair, debris, particles, dust, etc.) accumulate in the dust collection device, requiring the user to replace or disassemble and clean the dust collection device. Therefore, a prompt message needs to be issued indicating that the dust collection device needs to be processed.

[0061] Specifically, the third command to turn off the air purifier includes the command to turn off the fan and the command to stop the filter from rotating.

[0062] The air purifier control method provided in this embodiment can clean the filter surface 360° and clean the dust collection device in a timely manner, which can better solve the problem of air purifier filters needing manual cleaning.

[0063] This embodiment provides a control method for an air purifier, which can be used in computer equipment. The air purifier includes a filter, an air duct, a dust collection device, a dust collection device, and a fan. The filter is used to filter the air flowing through the air purifier. The air duct has a first state in a purification mode and a second state in a dust removal mode. In the first state, the air passage area of ​​the air duct is a first region; in the second state, the air passage area of ​​the air duct is a second region, wherein the first area of ​​the first region is larger than the second area of ​​the second region. The dust collection device includes a suction port and a transfer port. The suction port faces the filter and is used to collect adsorbed matter on the filter. The transfer port is connected to a first end of the second region. The dust collection device is connected to a second end of the second region. The fan provides the power for air to flow within the air purifier. In purification mode, under the action of the fan, air passes sequentially through the filter and the first region of the air duct within the air purifier. In dust removal mode, under the action of the fan, air passes sequentially through the filter, the dust collection device, the second region of the air duct, and the dust collection device within the air purifier. The filter is rotatably mounted on the base of the air purifier; the vacuum cleaner is fixedly mounted on the base, and the vacuum port can cover the filter.

[0064] Figure 4 This is a flowchart of another air purifier control method according to an embodiment of the present invention, such as... Figure 4 As shown, the process includes the following steps:

[0065] Step S401: When the air purifier is turned on, a fourth command is issued indicating that the air duct is in the first state, so that the air purifier enters the purification mode.

[0066] As described above, a blade drive device is installed on the air duct. This device drives the blades to rotate, causing the air duct to switch between a first state and a second state. It can be understood that a fourth command is sent to the aforementioned drive device, and under its action, the air duct can be in the first state. For example, as... Figure 2 As shown, when the air duct is in the first state, air can pass through the middle and all sides of the air duct.

[0067] The above step S401 can also be replaced by: when a purification command is received, issuing a fourth command that the air duct is in the first state, so that the air purifier enters the purification mode.

[0068] Step S402: Obtain the second running time of the air purifier in purification mode.

[0069] Step S403: When the second running time reaches the preset second running time threshold, a dust removal command is issued.

[0070] In other words, in purification mode, under the action of the fan, the air passes through the filter and the first area of ​​the air purifier in sequence. When the purification reaches a certain time, the foreign objects (such as hair, debris, particles, dust, etc.) in the filter will reach a certain amount, and the filter needs to be automatically cleaned.

[0071] It should be noted that the dust removal mode can also be entered according to the user's needs. That is, when the instruction to start the dust removal mode is received, a dust removal command will be issued.

[0072] Step S404: When a dust removal command is received, a first command is issued that the air duct is in the second state and a second command is issued that the filter screen rotates on the base, so that the air purifier enters the dust removal mode.

[0073] Step S405: Obtain the first running time of the air purifier in dust removal mode.

[0074] Step S406: When the first running time reaches the preset first time threshold, issue a third command to shut down the air purifier and issue a prompt message that the dust collection device needs to be processed.

[0075] To illustrate the control method of the air purifier in this embodiment of the invention more clearly, a specific example is given. Figure 5 This is a flowchart illustrating an example of an air purifier control method according to an embodiment of the present invention, such as... Figure 5 As shown, the control method for an air purifier includes the following steps:

[0076] When the air purifier is in purification mode, air is drawn in from the bottom. Inside the purifier, the air passes sequentially through the filter, the center and sides of the air duct, and finally exits from the top. During this initial purification period, the filter does not rotate. After a certain time, some debris may adhere to the filter surface. At this point, the air purifier's dust removal mode needs to be activated to remove the debris using a vacuum cleaner. When dust removal mode is activated, the filter rotates using a bottom-mounted rotating mechanism to ensure that the filter surface is cleaned from all 360°.

[0077] like Figure 3 As shown, when the purification mode is activated for a set threshold (e.g., 1 week or 160 hours) or when the user can manually set the dust removal mode to be activated, the purification mode will stop and the dust removal mode will be activated. Otherwise, the dust removal mode will not be activated. When the dust removal mode runs for the controller's set threshold (e.g., 1 hour), the air purifier will turn off and remind the user on the air purifier's display interface to replace or disassemble and clean the dust collection box. This removes foreign objects from the surface of the filter element, ensuring the user's physical and mental health.

[0078] The air purifier control method provided in this embodiment has the following beneficial effects:

[0079] 1. It effectively solves the problem that the filter screen of traditional filter-type air purifiers needs to be cleaned manually, simplifies the complexity of use for users, and improves the user experience.

[0080] 2. It effectively solves the problem of foreign matter accumulating on the surface of the filter screen after long-term use of traditional filter-type air purifiers, thereby reducing the purification efficiency of the filter element.

[0081] 3. By changing the blades, the dust removal mode and purification mode of the purifier can be switched, effectively improving the dust removal and purification efficiency of the purifier.

[0082] This embodiment also provides a control device for an air purifier, which is used to implement the above embodiments and preferred embodiments; details already described will not be repeated. As used below, the term "module" can refer to a combination of software and / or hardware that implements a predetermined function. Although the device described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.

[0083] This embodiment provides a control device for an air purifier, such as... Figure 7 As shown, it includes a mode adjustment module 601. When a dust removal command is received, the mode adjustment module issues a first instruction that the air duct is in a second state, causing the air purifier to enter dust removal mode.

[0084] In one optional embodiment, the air purifier's control device further includes a filter state adjustment module 602. Upon receiving a dust removal command, the filter state adjustment module issues a second instruction for the filter to rotate on its base.

[0085] In one optional embodiment, the control device for the air purifier further includes a first acquisition module 603, an air purifier shutdown module 604, and a prompt message sending module 605. The acquisition module is used to acquire the first operating time of the air purifier in dust removal mode; the air purifier shutdown module is used to issue a third command to shut down the air purifier; and the prompt message sending module is used to issue a prompt message indicating that the dust collection device needs to be processed.

[0086] In one optional embodiment, the control device of the air purifier further includes a dust removal command issuing module 606. When the air purifier is running in purification mode, the first acquisition module is also used to acquire a second running time of the air purifier in purification mode; when the second running time reaches a preset second duration threshold, the dust removal command generating module is used to issue a dust removal command.

[0087] In one optional embodiment, the control device of the air purifier further includes a second acquisition module.
