[0026] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0027] See also Figures 1 to 5 According to an embodiment of the utility model, the utility model provides an air purification device, which is used to be installed on a ceiling machine. The air purification device includes: a purification component 2 and a detection component 3. The purification component 2 is arranged at the air inlet 11 of the ceiling machine to purify the air entering the ceiling machine; the detection component 3 is arranged at the air outlet 12 of the ceiling machine, and at least part of the detection component 3 is used to detect the dust accumulation on the inner wall of the air outlet 12; to control whether at least part of the purification component 2 performs a purification action according to the detection condition of at least part of the detection component 3.

[0028] It can be seen that the air purification device provided by the utility model is provided with a purification component 2 and a detection component 3, and the purification component 2 is arranged at the air inlet 11 of the ceiling machine, and the detection component 3 is arranged at the air outlet 12 of the ceiling machine, so that the air entering the ceiling machine can be purified by the purification component 2, thereby improving the air quality entering the air conditioner. At the same time, the dust accumulation on the inner wall of the air outlet 12 is detected by at least part of the detection component 3, so that the dust accumulation on the inner wall of the air outlet 12 can be automatically and continuously monitored without relying on the user's naked eye observation, thereby improving the timeliness and accuracy of monitoring, and effectively avoiding the secondary pollution of indoor air caused by excessive dust accumulation on the inner wall of the air outlet 12, and maintaining the continuous freshness and health of indoor air. Furthermore, according to the detection situation of at least part of the detection component 3, at least part of the purification component 2 is controlled to perform the purification action, so that the working state of the purification component 2 is automatically adjusted according to the feedback of at least part of the detection component 3, ensuring the efficiency and accuracy of air purification. This design not only reduces the burden of users manually checking and cleaning the air outlets, significantly improves the convenience and efficiency of maintenance, but also creates a healthier and more comfortable indoor environment for users by continuously optimizing air quality. In addition, the automatic adjustment mechanism also helps to save energy and reduce emissions, and can effectively reduce operating costs and improve overall environmental performance. The air purification device can effectively solve the technical problem in the prior art that it is difficult for users to intuitively monitor the dust accumulation at the air outlet due to the special installation location of the ceiling machine.

[0029] In this embodiment, if Figure 1 and Figure 2As shown, the detection component 3 includes: a brush 31 and a detection member, the brush 31 is movably arranged in the air outlet 12, the brush 31 contacts the inner wall of the air outlet 12, so that the inner wall of the air outlet 12 is cleaned by the brush 31; the detection member is arranged at the air outlet 12, and the detection member is used to detect the particles brought up during the cleaning process of the brush 31, so as to control whether at least part of the purification component 2 performs the purification action according to the concentration of the particles detected by the detection member. Among them, the detection member forms at least part of the detection component 3. With such a structural arrangement, the brush 31 contacts the inner wall of the air outlet 12, and the dust attached to the inner wall of the air outlet 12 can be cleaned down by the movement of the brush 31, and the detection member can detect the concentration of the particles brought up during the cleaning process, and then judge the dust accumulation on the inner wall of the current air outlet 12, so as to grasp the cleaning state of the air outlet 12 in real time, without waiting or relying on external detection, and ensure the immediate responsiveness of air purification. In addition, by arranging the brush 31 movably, the dust on the inner wall of the air outlet 12 can be automatically cleaned, which reduces the frequency of manual cleaning, simplifies maintenance work, reduces maintenance costs, and improves user convenience and overall use experience. It also effectively avoids secondary pollution of indoor air caused by dust accumulation at the air outlet.

[0030] In a specific implementation process, when the detection element detects that the concentration of particulate matter is greater than or equal to a preset threshold, at least part of the purification component 2 starts to perform purification work.

[0031] In the specific implementation process, in order to make the data detected by the detection member more accurate, the detection member is located at the edge of the air outlet 12, that is, near the running track of the brush 31. There is at least one detection member.

[0032] In actual work, the preset threshold is set to 35ug / m 2 The detection part is a PM sensor.

[0033] In the specific implementation process, Figure 1 and Figure 2 As shown, the housing 1 of the ceiling machine is provided with an air inlet 11 and an air outlet 12, and the inner wall of the housing 1 forms the inner wall of the air outlet 12; the detection component 3 also includes: a driving structure 33, which is movably arranged in the air outlet 12; a brush 31 is arranged on the driving structure 33, and the driving structure 33 is used to drive the brush 31 to move along the circumferential direction of the inner wall of the housing 1. With such a structural arrangement, by arranging the driving structure 33 in the air outlet 12, the brush 31 can move along the circumferential direction of the inner wall of the housing 1, so that the dust on the inner wall of the air outlet 12 can be cleaned.

[0034] In the specific implementation process, Figure 1 and Figure 2As shown, the driving structure 33 includes: a driving wheel 331, a plurality of rotating wheels 332 and a transmission belt 333. The driving wheel 331 and the plurality of rotating wheels 332 are both rotatably arranged in the air outlet 12, and the driving wheel 331 and the plurality of rotating wheels 332 are arranged at intervals along the circumferential direction of the air outlet 12; the transmission belt 333 is respectively mounted on the driving wheel 331 and the plurality of rotating wheels 332, so as to drive the transmission belt 333 and each rotating wheel 332 to move by rotating the driving wheel 331; wherein, the brush 31 is installed on the transmission belt 333, so as to drive the brush 31 to move along the circumferential direction of the inner wall of the shell 1 through the transmission belt 333, thereby realizing the function of cleaning the inner wall of the air outlet 12.

[0035] In the specific implementation process, Figure 2 As shown, the ceiling machine has an evaporator 5, which is located in the shell 1, and the outer wall of the evaporator 5 and the inner wall of the shell 1 form an air outlet 12. The driving wheel 331, multiple rotating wheels 332 and the transmission belt 333 are arranged in the gap between the evaporator 5 and the shell 1 (that is, the driving wheel 331, multiple rotating wheels 332 and the transmission belt 333 are arranged in the air outlet 12). Among them, the cross section of the evaporator 5 is rectangular, and the driving wheel 331 and the multiple rotating wheels 332 are respectively located at each vertex of the evaporator 5 and are in a symmetrical balance state. The transmission belt 333 is respectively mounted on the driving wheel 331 and the multiple rotating wheels 332, so that when the driving wheel 331 rotates, the transmission belt 333 can drive the brush 31 to move along the circumferential direction of the inner wall of the shell 1. With such a structural arrangement, the driving wheel 331 and the plurality of rotating wheels 332 are respectively located at the top corners of the evaporator 5 and are in a symmetrically balanced state, thereby ensuring that the driving wheel 331, the plurality of rotating wheels 332 and the transmission belt 333 are installed in the air outlet 12 with uniform force, reducing vibration or noise that may be caused by structural imbalance and extending service life.

[0036] In a specific implementation process, the driving structure 33 further includes: a driving member, which is drivingly connected to the driving wheel 331 so as to drive the driving wheel 331 to rotate through the driving member.

[0037] In the actual working process, after the fan is turned on, the driving member starts to drive the driving wheel 331 to start moving, and then the transmission belt 333 drives the brush 31 to start moving, and then the detection member detects the particle concentration of the particles (i.e., dust) brought up by the brush 31 when cleaning the inner wall of the air outlet 12 (i.e., the detection member detects the particles brought up by the brush 31 during the cleaning process). When the particle concentration detected by the detection member is less than 35ug / m 2 When the concentration of particles detected by the detection element is greater than or equal to 35ug / m 2At the same time, at least part of the purification component 2 performs a purification action, and the brush 31 continues to move along the circumferential direction of the inner wall of the housing 1. Then, the inner wall of the air outlet 12 is cleaned, thereby achieving the effect of cleaning the inner wall of the air outlet 12.

[0038] In the specific implementation process, Figure 1 and Figure 2 As shown, the ceiling machine has a plurality of air guide blades 4, which are arranged at intervals on the transmission belt 333, so that the transmission belt 333 rotates to drive the plurality of air guide blades 4 to move in the circumferential direction around the air outlet 12; wherein the brush 31 is located between two adjacent air guide blades 4 among the plurality of air guide blades 4, and the brush 31 is arranged at intervals from two adjacent air guide blades 4 among the plurality of air guide blades 4. With such a structural arrangement, when the transmission belt 333 moves, the plurality of air guide blades 4 can be driven to rotate, thereby increasing the air outlet angle of the ceiling machine.

[0039] In the specific implementation process, Figure 1 As shown, the detection component 3 also includes: a mounting frame 34, which is arranged on the transmission belt 333 and extends toward the inner wall of the air outlet 12; a brush 31 is rotatably mounted on the mounting frame 34; wherein the axial direction of the brush 31 is perpendicular to the extension direction of the mounting frame 34. With such a structural arrangement, the brush 31 is connected to the transmission belt 333 through the mounting frame 34, so that the brush 31 can contact the inner wall of the air outlet 12. At the same time, the brush 31 is rotatably mounted on the mounting frame 34, so that the brush 31 can more flexibly adapt to the contour of the inner wall of the air outlet 12, and can effectively contact and clean both the straight part and the corner area, thereby improving the cleaning efficiency and coverage. In addition, the axial direction of the brush 31 is perpendicular to the extension direction of the mounting frame 34, which can increase the contact area between the brush 31 and the inner wall of the air outlet 12, thereby improving the cleaning effect.

[0040] In a specific implementation process, the brush 31 is detachably connected to the mounting frame 34, which is convenient for regular cleaning or replacement of the brush and simplifies maintenance work.

[0041] In this embodiment, if Figure 1 and Figures 3 to 5As shown, the purification component 2 includes: a filter structure 21 and an electrostatic adsorption structure 22, the filter structure 21 and the electrostatic adsorption structure 22 are sequentially arranged on the air inlet 11 along the air inlet direction; the filter structure 21 is used to filter the particles in the air entering the air inlet 11; the electrostatic adsorption structure 22 is used to purify the particles in the air passing through the filter structure 21; wherein the electrostatic adsorption structure 22 forms at least part of the purification component 2. With such a structural arrangement, the filter structure 21 and the electrostatic adsorption structure 22 are sequentially arranged on the air inlet 11 along the air inlet direction, which can achieve multi-stage filtration of the air entering the air inlet 11 and effectively remove the particles and pollutants in the air. The electrostatic adsorption structure 22 is further arranged between the filter structure 21 and the interior of the ceiling machine, which can further improve the purification effect, thereby ensuring the internal air quality of the ceiling machine and reducing the dust and pollutant deposition inside the ceiling machine, extending the service life of the equipment, and reducing the maintenance and cleaning frequency.

[0042] The air inlet direction refers to the direction in which the air flows into the ceiling machine. Figure 1 As shown, the direction pointed by arrow A is the air inlet direction.

[0043] In actual operation, if the concentration of particles detected by the detection element is less than the preset threshold, it indicates that the air quality outside is relatively good at this time, and the air entering the air inlet 11 only needs to be filtered through the filter structure 21, thereby effectively removing larger particles and impurities in the air and maintaining low energy consumption, thereby saving energy. When the concentration of particles detected by the detection element is greater than or equal to the preset threshold, the electrostatic adsorption structure 22 is activated to further purify the air entering and passing through the filter structure 21, thereby ensuring the indoor air quality and protecting the health of users.

[0044] In actual working process, the filtering structure 21 is a filtering net.

[0045] In the specific implementation process, the electrostatic adsorption structure 22 includes: a discharge plate 221 and a negative plate 222, which are sequentially arranged in the air inlet 11 along the air inlet direction; the discharge plate 221 is used to ionize the particles in the air passing through the filter structure 21; the negative plate 222 has an opposite electrical property to the discharge plate 221; so that the ionized particles are adsorbed on the discharge plate 221 and / or the negative plate 222. With such a structural setting, the particles in the air are ionized by the discharge plate 221, so that the tiny particles that are originally difficult to be captured by physical filtration are charged, and then the discharge plate 221 and / or the negative plate 222 are used to attract these charged particles, which effectively improves the removal rate of fine particles (such as PM2.5, viruses, bacteria, etc.), and the purification efficiency is significantly higher than that of the method that relies solely on physical filtration. The electrostatic adsorption structure 22 is seamlessly integrated with the filtering structure 21, which does not affect the normal operation of the original system and can be flexibly started and stopped automatically according to the air quality conditions, thereby enhancing the overall flexibility and efficiency of the air purification system.

[0046] In actual operation, when the electrostatic adsorption structure 22 starts to perform purification, the discharge plate 221 with high voltage rectification begins to ionize the surrounding air. When the particles (foreign matter) in the air pass through, they will be positively or negatively charged due to the interaction of charges. In general, these particles will be more positively charged because the positive ions released by the discharge plate 221 are more easily captured by the particles. Subsequently, according to the principle of opposite charges attracting each other, the positively charged particles will be attracted to the negative plate 222, and the negatively charged particles will be attracted to the discharge plate 221.

[0047] Among them, the negative plate plays the role of a "dust collecting electrode" in the electric field, maintaining a zero potential or a relatively low potential, so that it can effectively attract and capture positively charged particles.

[0048] In the specific implementation process, the electrostatic adsorption structure 22 also includes: a micro-current detection element, which is arranged between the discharge plate 221 and the negative plate 222, and the micro-current detection element is used to detect the micro-current generated between the particles adsorbed on the discharge plate 221 and the discharge plate 221, and / or, to detect the micro-current generated between the particles adsorbed on the negative plate 222 and the negative plate 222; to judge the purification state of the electrostatic adsorption structure 22 and the dust accumulation of the electrostatic adsorption structure 22 according to the micro-current detected by the micro-current detection element. With such a structural setting, by setting the micro-current detection element between the discharge plate 221 and the negative plate 222, the purification state of the electrostatic adsorption structure 22 and the dust accumulation of the electrostatic adsorption structure 22 can be judged according to the micro-current detected by the micro-current detection element. At the same time, by setting the micro-current detection element, it can also help monitor the operating state of the electrostatic adsorption structure 22. Abnormal current readings may indicate that there is a fault in the system, such as a decrease in the efficiency of the discharge plate 221, dust saturation of the negative plate 222, or electrical connection problems.

[0049] In actual operation, when charged particles move to the negative plate 222 and deposit on its surface, the charges carried by these particles will form a current path with the negative plate, and even a tiny charge transfer will generate a weak current. As more and more charged particles are deposited, more charge transfers will occur, resulting in a brief increase in microcurrent. Furthermore, by setting up a microcurrent detection device, the fluctuation of this microcurrent can be monitored, and the microcurrent detected by the microcurrent detection device can indirectly reflect how many charged particles are adsorbed per unit time, thereby knowing the activity frequency of the electrostatic adsorption structure 22 in capturing foreign matter. According to the activity frequency, it can be seen what the quality of the air entering the air inlet 11 is.

[0050] For example, when there are more dust particles in the air, it means that the ionization effect generated by the discharge plate 221 is more active, and more charged particles will be attracted to the negative plate 222 or the discharge plate 221. This will cause the charge accumulation speed on the negative plate 222 to accelerate, and the frequency and intensity of the microcurrent formation may increase, reflecting that the electrostatic adsorption structure 22 is dealing with a higher pollutant load. If there are fewer dust or other particles in the air, the particles that are ionized and attracted to the negative plate 222 will also be reduced accordingly, so the charge accumulation speed on the negative plate 222 will slow down, and the frequency and intensity of the microcurrent formation will be relatively reduced, which can indirectly indicate that the ambient air quality is good and the workload of the electrostatic adsorption structure 22 is reduced.

[0051] At the same time, as particulate matter continues to accumulate on the negative plate 222, the efficiency of charge transfer and current characteristics will be affected. When dust accumulation increases, it may affect the normal release and flow of charge, resulting in changes in the intensity, frequency or pattern of the microcurrent. At this time, it can be determined whether the electrostatic adsorption structure 22 needs to be cleaned or maintained based on these changes detected by the microcurrent detection element.

[0052] In this embodiment, the air purification device also includes: a control component, the purification component 2 and the detection component 3 are both connected to the control component, and the control component is used to control whether at least part of the purification component 2 performs a purification action and whether the detection component 3 performs a detection action.

[0053] In actual working process, the working process of air purification device is:

[0054] When the skylight machine is turned on and the fan is started, the control component controls the driving structure 33 of the detection component 3 to move, so that the brush 31 moves along the circumferential direction of the inner wall of the air outlet 12, and then the brush 31 cleans the dust on the inner wall of the air outlet 12. During the cleaning process, the detection component detects the particles brought up by the brush 31, and then feeds back the detected particle concentration to the control component.

[0055] When the particle concentration detected by the detector is less than 35ug / m 2 When the air is filtered, the control component controls the driving structure 33 to stop moving, controls the electrostatic adsorption structure 22 not to perform purification action, and only filters the air through the filtering structure 21.

[0056] When the particle concentration detected by the detector is greater than or equal to 35ug / m 2 When the air quality at the air inlet 11 and the air outlet 12 is optimized, the control component controls the driving structure 33 to continue to move, so that the brush 31 cleans the inner wall of the air outlet 12, and the detection component also performs real-time detection. At the same time, the control component also controls the electrostatic adsorption structure 22 to perform purification work, and the micro-current detection component in the electrostatic adsorption structure 22 starts to perform micro-current detection. Thus, the air quality at the air inlet 11 and the air outlet 12 is optimized at the same time.

[0057] If the micro-current value detected by the micro-current detection component is equal to 0.0 mA (using a rounding mechanism), it means that the quality of the external air is good, and the control component controls the electrostatic adsorption structure 22 to stop the purification action.

[0058] When the microcurrent value detected by the microcurrent detector is equal to 0.0mA and the particle concentration detected by the detector is greater than or equal to 35ug / m 2 When the particle concentration detected by the detection unit is less than 35ug / m2 When the microcurrent value detected by the microcurrent detection component is approximately equal to 0.0 mA, it means that the internal environment of the ceiling machine is good and the external air quality is good. The control component controls the detection component 3 and the electrostatic adsorption structure 22 to stop working. When the particle concentration detected by the detection component again is less than 35ug / m 2 When the microcurrent value detected by the microcurrent detection component is greater than 0.0mA, it means that the internal environment of the ceiling machine is good and the external air quality is poor, and the electrostatic adsorption structure 22 will continue to purify. When the particle concentration detected by the detection component again is greater than or equal to 35ug / m 2 When the microcurrent value detected by the microcurrent detection component is greater than 0.0mA, it means that the internal environment of the ceiling machine may be poor and / or the external air quality may be poor. The control component controls the detection component 3 and the electrostatic adsorption structure 22 to continue working, and then continues to observe.

[0059] In the specific implementation process, the air purification device also includes: a receiving component, which is arranged on the ceiling machine and is used to receive a predetermined instruction issued by the user; the receiving component is connected to the control component, so that the control component controls the purification component 2 and / or the detection component 3 according to the predetermined instruction received by the receiving component. With such a structural setting, through the receiving component, the user can send specific instructions to the control component according to his own needs or changes in the indoor environment, thereby realizing a high degree of personalization and customization of the air purification process and improving the user experience.

[0060] The utility model provides an air purification device, which is used to be installed on a ceiling machine. The air purification device includes: a purification component 2 and a detection component 3.
