Description

Technical Field

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

[0002] Currently, the most common filtration method in air purifiers is the use of composite filters. As users use the purifier over time, the filters become increasingly dirty, and the purification effect deteriorates. To extend the filter's lifespan, a high-voltage module can be installed in the air purifier. This module uses a high-voltage electrostatic field to attract and remove dust.

[0003] However, during the operation of the high-voltage module, oxygen molecules in the air surrounding the metal filter are ionized and decomposed into oxygen atoms. In this process, these oxygen atoms collide with other oxygen molecules to form ozone molecules. When the ozone concentration exceeds 100 ppb, the human respiratory tract is easily irritated and inflamed; when the concentration reaches 50,000 ppb, it can be life-threatening. Therefore, when a high-voltage module is added to an air purifier, the ozone concentration produced by the air purifier needs to be controlled. Summary of the Invention

[0004] In view of this, the present invention provides a control method, device, computer equipment and air purifier for controlling the ozone concentration generated by the air purifier when a high-voltage module is added to the air purifier.

[0005] In a first aspect, embodiments of the present invention provide a control method for an air purifier, the air purifier including a high-voltage module and an ultraviolet lamp, the method including the following steps: after the high-voltage module and the ultraviolet lamp are started, a first ozone concentration at the air outlet of the air purifier is obtained; the brightness of the ultraviolet lamp is adjusted according to the first ozone concentration at the air outlet.

[0006] The air purifier control method provided in this embodiment of the invention, after the high-voltage module and ultraviolet lamp are started, obtains the first ozone concentration at the air purifier outlet and adjusts the brightness of the ultraviolet lamp according to the first ozone concentration at the air outlet. This allows the rate at which the high-voltage module generates ozone and the rate at which the ultraviolet lamp decomposes ozone to reach a balance, ensuring that the first ozone concentration at the air purifier outlet meets the standard requirements and does not have any adverse effects on the user.

[0007] In one optional implementation, adjusting the brightness of the ultraviolet lamp based on the first ozone concentration at the air outlet includes: reducing the brightness of the ultraviolet lamp when the first ozone concentration at the air outlet is less than a preset first threshold; increasing the brightness of the ultraviolet lamp when the first ozone concentration at the air outlet is greater than a preset second threshold; and keeping the brightness of the ultraviolet lamp unchanged when the first ozone concentration at the air outlet is greater than or equal to the first threshold and less than or equal to the second threshold.

[0008] This allows the rate at which the high-voltage module generates ozone to balance the rate at which the ultraviolet lamp decomposes ozone, ensuring that the initial ozone concentration at the air purifier's outlet meets the required standards and does not adversely affect the user.

[0009] In one optional implementation, before adjusting the brightness of the ultraviolet lamp based on the first ozone concentration at the air outlet, the method further includes: acquiring a second ozone concentration at the air purifier's air inlet and a third ozone concentration inside the air purifier; determining whether the high-voltage module is working properly based on the second ozone concentration at the air inlet and the third ozone concentration inside the air purifier; and when the high-voltage module is working properly, determining whether the ultraviolet lamp is working properly based on the first ozone concentration at the air outlet and the third ozone concentration inside the air purifier.

[0010] This eliminates the possibility of a malfunction in the high-voltage module and / or the UV lamp. The brightness of the UV lamp should only be adjusted when both the high-voltage module and the UV lamp are working properly.

[0011] In one optional implementation, determining whether the high-voltage module is working properly based on the second ozone concentration at the air inlet and the third ozone concentration inside includes: when the second ozone concentration at the air inlet is less than the third ozone concentration inside, it is determined that the high-voltage module is working properly; when the second ozone concentration at the air inlet is greater than or equal to the third ozone concentration inside for a preset first time period, it is determined that the high-voltage module has malfunctioned, and a first prompt message of high-voltage module malfunction is issued.

[0012] This allows for accurate determination of whether the high-voltage module is functioning normally or has malfunctioned.

[0013] In one optional implementation, determining whether the ultraviolet lamp is working properly based on the first ozone concentration at the air outlet and the third ozone concentration inside includes: determining whether the ultraviolet lamp is working properly when the first ozone concentration at the air outlet is less than the third ozone concentration inside; and determining that the ultraviolet lamp is malfunctioning when the first ozone concentration at the air outlet is greater than or equal to the third ozone concentration inside for a preset second time period, and issuing a second prompt message indicating that the ultraviolet lamp is malfunctioning.

[0014] This allows for an accurate determination of whether the UV lamp is working properly or malfunctioning.

[0015] In one optional implementation, the control method for the air purifier further includes the following steps: determining whether the second ozone concentration at the air inlet is greater than a preset first threshold; and issuing a third warning message indicating that the ozone concentration is too high when the second ozone concentration at the air inlet is greater than the first threshold.

[0016] This eliminates the possibility that the ozone concentration in the air itself exceeds the standard.

[0017] Secondly, embodiments of the present invention also provide a control device for an air purifier. The air purifier includes a high-voltage module and an ultraviolet lamp. The device includes an acquisition module and a brightness adjustment module. After the high-voltage module and the ultraviolet module are started, the acquisition module is used to acquire a first ozone concentration at the air outlet of the air purifier. The brightness adjustment module is used to adjust the brightness of the ultraviolet lamp according to the first ozone concentration at the air outlet.

[0018] Thirdly, 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 first aspect or any corresponding embodiment.

[0019] Fourthly, embodiments of the present invention also provide an air purifier, including the computer device of the third aspect.

[0020] Fifthly, 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 first aspect or any corresponding embodiment.

[0030] 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.

[0031] 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.

[0032] This embodiment provides a control method for an air purifier, which can be used in computer equipment. In this embodiment, the air purifier includes a high-voltage module (also called a voltage multiplier module) and an ultraviolet lamp (also called an ultraviolet light lamp). When the high-voltage module is working, oxygen molecules in the air surrounding the filter are ionized and decomposed into oxygen atoms. During this process, oxygen atoms collide with other oxygen molecules to form ozone molecules. To control the ozone concentration produced by the air purifier, an ultraviolet lamp is installed inside the air purifier. The ultraviolet lamp emits ultraviolet light. Ozone is extremely unstable; after absorbing ultraviolet light with a wavelength of 254nm, it decomposes into dissolved oxygen. The energy provided by the ultraviolet light can break the chemical bonds in ozone, generating oxygen; that is, ozone becomes oxygen after absorbing ultraviolet light. Since ultraviolet lamps are low in cost, this embodiment of the invention uses ultraviolet lamps to decompose ozone, which can reduce the cost of ozone decomposition. Moreover, while decomposing ozone, the ultraviolet lamp can also quickly and effectively kill bacteria, viruses, and other microorganisms inside the machine. Microorganisms undergo photochemical reactions under ultraviolet light irradiation, thereby destroying their nucleic acids and rendering them inactive.

[0033] Figure 1 This is a flowchart of an air purifier control method according to an embodiment of the present invention, such as... Figure 1 As shown, the process includes the following steps:

[0034] Step S101: After the high-voltage module and ultraviolet lamp are started, obtain the first ozone concentration at the air outlet of the air purifier.

[0035] Specifically, a first ozone sensor can be installed at the air outlet of the air purifier to obtain the first ozone concentration at the air outlet of the air purifier.

[0036] Step S102: Adjust the brightness of the ultraviolet lamp according to the first ozone concentration at the air outlet.

[0037] Specifically, when a UV lamp is controlled using PWM, the brightness of the UV lamp can be controlled by adjusting the duty cycle of the PWM wave.

[0038] This is because the initial ozone concentration at the air outlet after the high-voltage module and UV lamp are activated reflects the matching rate between the ozone generation rate of the high-voltage module and the ozone decomposition rate of the UV lamp. When the voltage and power of the high-voltage electric field of the high-voltage module remain constant, the brightness of the UV lamp determines the ozone decomposition rate. The brighter the UV lamp, the faster the ozone decomposition rate. Therefore, the brightness of the UV lamp can be adjusted according to the initial ozone concentration at the air outlet.

[0039] The air purifier control method provided in this embodiment of the invention, after the high-voltage module and ultraviolet lamp are started, obtains the first ozone concentration at the air purifier outlet and adjusts the brightness of the ultraviolet lamp according to the first ozone concentration at the air outlet. This allows the rate at which the high-voltage module generates ozone and the rate at which the ultraviolet lamp decomposes ozone to reach a balance, ensuring that the first ozone concentration at the air purifier outlet meets the standard requirements (e.g., less than 50 ppb) and does not have any adverse effects on the user.

[0040] It should be noted that air purifiers also contain fans. In related technologies, adjusting the fan speed changes the residence time of ozone inside the air purifier, thus balancing the rate at which the high-voltage module generates ozone and the rate at which the ultraviolet lamp decomposes it. However, controlling the fan speed requires a DC motor, which is relatively expensive. This invention, however, only requires improvements to the computer program. By controlling the PWM wave output and adjusting the PWM wave duty cycle, the brightness of the ultraviolet lamp is controlled, thereby controlling the photolysis rate of the ultraviolet lamp and the internal ozone concentration. No hardware modifications to the air purifier are required, reducing production costs.

[0041] This embodiment provides a control method for an air purifier, which can be used in computer equipment. Figure 2 This is a flowchart of another air purifier control method according to an embodiment of the present invention, such as... Figure 2 As shown, the process includes the following steps:

[0042] Step S201: After the high-voltage module and the ultraviolet lamp are started, obtain the first ozone concentration at the air outlet of the air purifier.

[0043] Specifically, a first ozone sensor can be set at the air outlet of the air purifier, and the first ozone concentration at the air outlet of the air purifier is obtained through the first ozone sensor.

[0044] Step S202: Adjust the brightness of the ultraviolet lamp according to the first ozone concentration at the air outlet.

[0045] Specifically, step S202 includes:

[0046] S2021: When the first ozone concentration at the air outlet is less than the preset first threshold, reduce the brightness of the ultraviolet lamp.

[0047] Specifically, when the ultraviolet lamp is controlled by PWM, the brightness of the ultraviolet lamp can be reduced by reducing the duty cycle of the PWM wave.

[0048] Exemplarily, Y = K(r - a) + Z, r < a, where Y represents the current brightness of the ultraviolet lamp, K represents the proportionality coefficient, r represents the first ozone concentration at the air outlet, a represents the first threshold; Z represents the initial brightness of the ultraviolet lamp.

[0049] S2022: When the first ozone concentration at the air outlet is greater than the preset second threshold, increase the brightness of the ultraviolet lamp.

[0050] Specifically, when the ultraviolet lamp is controlled by PWM, the brightness of the ultraviolet lamp can be increased by increasing the duty cycle of the PWM wave.

[0051] Exemplarily, Y = K(r - b) + Z, r < a, where Y represents the current brightness of the ultraviolet lamp, K represents the proportionality coefficient, r represents the first ozone concentration at the air outlet, b represents the second threshold; Z represents the initial brightness of the ultraviolet lamp.

[0052] S2022: When the first ozone concentration at the air outlet is greater than or equal to the first threshold and less than or equal to the second threshold, the brightness of the ultraviolet lamp remains unchanged.

[0053] Exemplarily, when the first threshold is represented by a and the second threshold is represented by b, being greater than or equal to the first threshold and less than or equal to the second threshold can be represented as a concentration range [a, b].

[0054] The air purifier control method provided in this embodiment of the invention, after the high-voltage module and ultraviolet lamp are started, obtains the first ozone concentration at the air purifier outlet and adjusts the brightness of the ultraviolet lamp according to the first ozone concentration at the air outlet. This allows the rate at which the high-voltage module generates ozone and the rate at which the ultraviolet lamp decomposes ozone to reach a balance, ensuring that the first ozone concentration at the air purifier outlet meets the standard requirements and does not have any adverse effects on the user.

[0055] This embodiment provides a control method for an air purifier, which can be used in computer equipment. Figure 3 This is a flowchart of another 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: After the high-voltage module and ultraviolet lamp are started, obtain the second ozone concentration at the air inlet of the air purifier and the third ozone concentration inside the air purifier.

[0057] Specifically, a second ozone sensor can be installed at the air purifier's air inlet to detect the ozone concentration at that location. A third ozone sensor can be installed inside the air purifier to detect the ozone concentration within the purifier. For example, the third ozone sensor can be positioned between the high-voltage module and the ultraviolet lamp.

[0058] Step S302: Determine whether the high-voltage module is working properly based on the second ozone concentration at the air inlet and the third ozone concentration inside.

[0059] Specifically, step S302 includes:

[0060] Step S3021: When the second ozone concentration at the air inlet is less than the third ozone concentration inside, the high-voltage module is determined to be working normally.

[0061] This is because ozone is generated inside the air purifier when the high-voltage module is working normally. Therefore, the second ozone concentration at the air purifier's air inlet is lower than the third ozone concentration inside the air purifier.

[0062] Step S3022: When the second ozone concentration at the air inlet is greater than or equal to the third ozone concentration inside for a preset first time period, it is determined that the high-voltage module has failed, and a first warning message of high-voltage module failure is issued.

[0063] This is because if the second ozone concentration at the air inlet is greater than or equal to the third ozone concentration inside the unit for a preset first time period, it indicates that no ozone is being produced inside the air purifier, and the high-voltage module has malfunctioned. This eliminates the possibility of accidental factors and accurately determines whether the high-voltage module has malfunctioned.

[0064] Step S303: When the high-voltage module is working normally, obtain the first ozone concentration at the air purifier outlet.

[0065] Step S304: Determine whether the ultraviolet lamp is working properly based on the first ozone concentration at the air outlet and the third ozone concentration inside.

[0066] Specifically, step S304 includes:

[0067] Step S3041: When the first ozone concentration at the air outlet is less than the third ozone concentration inside, determine whether the ultraviolet lamp is working properly.

[0068] This is because when the ultraviolet lamp is working normally, it decomposes the ozone produced inside the air purifier, so the first ozone concentration at the air outlet is less than the third ozone concentration inside.

[0069] Step S3042: When the first ozone concentration at the air outlet is greater than or equal to the third ozone concentration inside for a preset second time period, it is determined that the ultraviolet lamp has malfunctioned, and a second prompt message of ultraviolet lamp malfunction is issued.

[0070] This is because if the first ozone concentration at the air outlet is greater than or equal to the third ozone concentration inside the air outlet for a preset second time period, it indicates that the ultraviolet lamp has not decomposed the ozone and the ultraviolet lamp has malfunctioned.

[0071] Step S305: Adjust the brightness of the ultraviolet lamp according to the first ozone concentration at the air outlet.

[0072] The air purifier control method provided in this embodiment can balance the ozone generation rate of the high-voltage module and the ozone decomposition rate of the ultraviolet lamp by adjusting the brightness of the ultraviolet lamp, thereby ensuring that the first ozone concentration at the air outlet of the air purifier meets the standard requirements and does not have an adverse effect on the user; and it can also eliminate the possibility of malfunction of the high-voltage module and / or the ultraviolet lamp.

[0073] To provide a detailed explanation of the control methods for air purifiers, a specific example is given. For instance... Figure 4 As shown, the air purifier control method of this embodiment includes the following steps:

[0074] 1. When the air purifier is turned on, the first ozone sensor, the second ozone sensor, and the third ozone sensor will detect the ozone concentration in real time and return the values ​​to the system.

[0075] 2. Obtain the second ozone concentration r1 at the air inlet of the air purifier and the third ozone concentration r2 inside the air purifier;

[0076] 3. When the second ozone concentration r1 at the air inlet is greater than or equal to the third ozone concentration r2 inside, and the air purifier has been running for a certain period of time, if neither the second ozone concentration r1 nor the third ozone concentration r2 changes, it indicates that no ozone is being produced inside the air purifier, the high-voltage module is malfunctioning, and the system will send a fault reminder to the user.

[0077] 4. When the second ozone concentration r1 at the air inlet is greater than 50 ppb, it indicates that the ozone concentration in the room where the air purifier is located is too high. The system will issue an alarm to remind the user that the current ozone concentration is within a range that is harmful to the human body.

[0078] 5. Only when the second ozone concentration r1 at the air inlet is less than the third ozone concentration r2 inside the air purifier does it indicate that the high-voltage module inside the air purifier is ionizing and generating ozone. Then, the values ​​of the first ozone concentration r3 at the air outlet and the third ozone concentration r2 inside the air are collected. If the value of the first ozone concentration r3 at the air outlet is greater than (i.e., ...) for an extended period... Figure 4 If the runtime of the UV lamp exceeds the preset duration T and the value of the third ozone concentration r2 within the time frame is greater than the preset duration T, it indicates that the UV lamp has malfunctioned and is not decomposing ozone. At this time, the system will report a UV lamp malfunction.

[0079] 6. Only when the first ozone concentration (r3) at the air outlet is less than the third ozone concentration (r2) inside the air purifier is it considered that the air purifier is continuously generating and depleting ozone. Therefore, an ultraviolet (UV) lamp is needed to decompose ozone, and the brightness of the UV lamp needs to be adjusted to balance the rate of ozone generation and decomposition inside the air purifier.

[0080] 7. When the first ozone concentration r3 at the air outlet is less than the preset ozone concentration, it means that the concentration value is already very small. The system will reduce the duty cycle of the internal output PWM wave, reduce the power and brightness of the ultraviolet lamp, reduce the rate at which ozone is decomposed, and thus slowly increase the concentration to the preset value.

[0081] 8. When the initial ozone concentration r3 at the air outlet is exactly within the preset concentration range [a, b] (i.e., a < r3 < b), the decomposition and generation of ozone molecules inside are at an equilibrium value. At this time, no internal adjustments are needed; simply maintain the current equilibrium value. The duty cycle will only be adjusted according to the concentration value when the concentration changes again.

[0082] 9. When the first ozone concentration r3 at the air outlet is greater than the preset ozone concentration (i.e. r3 > b), the ozone concentration exceeds the preset range. The system needs to increase the duty cycle of the output PWM wave, increase the brightness of the ultraviolet lamp, and increase the ozone photolysis rate, thereby reducing the ozone concentration to the preset range [a, b].

[0083] 10. When the first ozone concentration r3 at the air outlet is less than the preset ozone concentration (i.e., r3 < a), the ozone concentration is below the preset concentration range. The system needs to reduce the duty cycle of the output PWM wave, reduce the brightness of the ultraviolet lamp, and reduce the rate of ozone photolysis.

[0084] In summary, the control method of the air purifier in this embodiment of the invention detects the ozone concentration at the air inlet, air outlet and inside the device using an ozone sensor, and controls the brightness of the ultraviolet lamp by controlling the output of the internal PWM wave and adjusting the duty cycle of the PWM wave, thereby controlling the photolysis rate of the ultraviolet light and controlling the internal ozone concentration. This ensures that the ozone concentration generated by the air purifier is controllable and harmless to the human body.

[0085] 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.

[0090] In some optional embodiments, the air purifier control device further includes a pre-processing module 503. Before adjusting the brightness of the ultraviolet lamp based on the first ozone concentration at the air outlet, the pre-processing module 503 includes: a first acquisition unit for acquiring a second ozone concentration at the air inlet of the air purifier and a third ozone concentration inside the air purifier; a high-voltage module operating status determination unit for determining whether the high-voltage module is operating normally based on the second ozone concentration at the air inlet and the third ozone concentration inside the air purifier; when the high-voltage module is operating normally, a second acquisition unit for acquiring the first ozone concentration at the air outlet of the air purifier; and an ultraviolet lamp operating status determination unit for determining whether the ultraviolet lamp is operating normally based on the first ozone concentration at the air outlet and the third ozone concentration inside the air purifier.

[0091] In some optional implementations, the high-voltage module operating status determination unit is used to: determine that the high-voltage module is working normally when the second ozone concentration at the air inlet is less than the third ozone concentration inside; and determine that the high-voltage module has malfunctioned when the second ozone concentration at the air inlet is greater than or equal to the third ozone concentration inside for a preset first time period, and issue a first prompt message of high-voltage module malfunction.

[0093] In some optional embodiments, the preprocessing module 503 further includes an air state detection unit. The air state detection unit is used to: determine whether the second ozone concentration at the air inlet is greater than a preset first threshold; and when the second ozone concentration at the air inlet is greater than the first threshold, issue a third alert message indicating that the ozone concentration is too high.

[0098] An internal fan 3 in the air purifier circulates air. When the voltage and power of the high-voltage electric field in the high-voltage module 2 remain constant, and the rotational speed of the internal fan 3 remains constant, the brightness of the ultraviolet lamp 6 determines the ozone decomposition rate. The brighter the ultraviolet lamp 6, the faster the decomposition rate. Specifically, the aluminum film 5 focuses the ultraviolet lamp 6.
