Description

Technical Field

[0001] The present application relates to the field of color calibration, and in particular to a multifunctional color calibration system. Background Art

[0002] Color calibration is to use the colors on the color card as standard colors using a color calibrator.

[0003] The patent document with application number CN202221819270.1 discloses the following Figure 1 The solution shown. A correction sensor is used to display the most accurate color of the product based on the color of the product in combination with a color card. In other technologies, the colors on the color card of a color calibrator are collected and uploaded for use as standard colors; then the color sensor obtains the color of the product, identifies the actual color information obtained, and replaces the obtained color with the standard color on the color card. For example, if the red color actually obtained by the color sensor has a color difference due to light, the red color obtained by the color sensor is replaced with the red color on the color card and displayed on a display module for people to visually view.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: The product usage scenarios of the above technology are relatively simple. When the product to be tested is in a dusty scene, the dust will adhere to the product to be tested, causing the color of the product to be tested to fade, turn yellow, or turn gray due to the dust. The color obtained by the color sensor will have errors, making it difficult to accurately identify the color of the product, resulting in inaccurate color calibrated by the color calibrator. Summary of the invention

[0005] In order to improve the problem that the color of the product to be inspected is affected by dust, resulting in inaccurate color calibrated by a color calibrator, the present application provides a multifunctional color calibration system.

[0006] The multifunctional color calibration system provided in this application adopts the following technical solution: A multifunctional color calibration system comprises: a support seat for placing a product to be detected and a color card; a color sensor for obtaining the color of the product to be detected; a color calibrator for calibrating the color obtained by the color sensor; a display module for displaying the color of the product to be detected after calibration; a filter component for forming a filter chamber, an outlet and a filter area connected to the filter chamber; a wind cleaning component arranged in the filter chamber; a flow guide component for forming a conical flow guide cavity and a spiral flow guide cavity at the outlet; wherein the color sensor and / or the color calibrator are installed in the conical flow guide cavity, and the conical flow guide cavity forms a conical opening smaller in size than the color sensor and / or the color calibrator; the spiral flow guide cavity is located at the edge of the conical flow guide cavity, and the spiral flow guide cavity is used to output air in a spiral state; the wind cleaning component is used to output air outward in the conical flow guide cavity and the spiral flow guide cavity after passing through the filter area, the filter chamber and the outlet in sequence.

[0007] By adopting the above-mentioned technical scheme, the purified air discharged outwardly through the conical guide cavity is blown onto the product to be inspected, so that the dust on the product to be inspected can be cleaned and the color of the product to be inspected can be more accurately obtained. In addition, the color sensor and / or the color calibrator are installed inside the conical guide cavity, so that the air flow path formed by the conical guide cavity discharging the purified air outward will coincide with the visual path for the color sensor and / or the color calibrator to obtain the color of the product to be inspected, so that the flow path formed by the purified air can be filled in the visual path for obtaining the color, avoiding excessive dust on the visual path from affecting the detection result, so that even if it is used in dusty places, the accuracy of color detection can be well guaranteed. The spiral guide cavity will make the air be output in a spiral state, so the flow speed of the air in the spiral state will be greater than the air output outward from the conical guide cavity, so that the dust between the flow channel formed by the conical guide cavity outputting the air outward and the air in the spiral state will move into the air in the spiral state under the action of pressure, thereby preventing external dust from entering the air output outward from the conical guide cavity, better ensuring that there is no dust on the visual path of color detection to affect the accuracy of detection, so that the color on the product can be detected more accurately, and at the same time, filtering the air and blowing it on the product to be detected can also play a role in purifying the air.

[0008] Optionally, a purification structure is arranged on the filter area, and the purification structure is a water-absorbing material; a water storage structure is arranged below the purification structure, and the purification structure is partially located in the water storage structure; the purification structure covers the filter area, and a plurality of filter holes are formed on the purification structure.

[0009] By adopting the above technical solution, the purification structure is a water-absorbing material, then the purification structure is moist, and the external air will first pass through the filter holes on the purification structure and then pass through the filter element, so that the external air can be purified twice. In addition, the purification structure is moist, and when the air passes through, the evaporation rate of the water on the purification structure will be accelerated, so that the water on the purification structure evaporates into water vapor and is output along with the air in the conical guide cavity and the spiral guide cavity, which plays a role in humidifying the surrounding environment and is beneficial to improving the surrounding environment. In addition, water vapor can reduce static electricity in the air, so that after the air containing water vapor is blown on the product, it can also effectively generate static electricity on the product and better prevent dust adhesion, which not only improves the accuracy of detection, but also helps to improve the surrounding environment.

[0010] Optionally, a wrapping shell is arranged on the outside of the purification structure, and the wrapping shell wraps the purification structure; the wrapping shell forms an inlet and a wrapping chamber connected to the inlet; the purification structure blocks the inlet; an air outlet structure is arranged at the inlet, and the air outlet structure is used to add external air into the wrapping chamber so that the pressure in the wrapping chamber is greater than the pressure in the filter chamber; the wrapping chamber is connected to the filter chamber through the filter hole and the filter area.

[0011] By adopting the above-mentioned technical solution, by utilizing the fact that the pressure in the wrapping chamber is greater than the pressure in the filtering chamber, the external air can enter the filtering chamber faster, thereby increasing the flow rate of the air discharged outward from the conical guide cavity and the spiral guide cavity, increasing the effect of the air blowing on the product to clean the product, and better improving the accuracy of product color detection.

[0012] Optionally, a first filter screen and a second filter screen are arranged in the filter area; wherein a plurality of first filter screens are arranged, and the first filter screen is arranged on the side of the filter chamber; the second filter screen is arranged on the bottom of the filter chamber; the side of the filter chamber is perpendicular to the bottom of the filter chamber; the direction in which external air enters the filter chamber through the second filter screen is the same as the direction in which the air is discharged from the outlet.

[0013] Optionally, a plurality of driving rollers are arranged in the wrapping chamber; the purification structure is a flexible material, and the purification structure is wound around the plurality of driving rollers; the plurality of driving rollers are used to enable the purification structure to form a plurality of filtering planes that partially match the first filter nets; a driving member is arranged on the driving roller, and the driving member is used to drive the driving roller to rotate so that the purification structure is transmitted outside the plurality of first filter nets.

[0014] By adopting the above technical solution, the purification structure will be driven outside the multiple first filter screens, so different positions of the purification structure can be in contact with the first filter screens at different positions, so that the purification structure can filter the air uniformly.

[0015] Optionally, a scraper is provided in the wrapping chamber, and the scraper is used to abut against the filtering structure; the scraper forms a first abutting surface and a second abutting surface; the filtering structure is located between the first abutting surface and the second abutting surface; the first abutting surface and the second abutting surface extend obtusely, and the first abutting surface and the second abutting surface both form an obtuse angle with the conveying direction of the filtering structure; wherein the first abutting surface and the second abutting surface are symmetrically arranged relative to the filtering structure, and the first abutting surface and the second abutting surface both abut against the filtering plane.

[0016] By adopting the above technical solution, the scraper can scrape off the dust and impurities on the purification structure, making the air filtering and purification effect better, and can also squeeze out and scrape off the water on the purification structure. If there is too much water on the purification structure, it is easy for the water to enter the filter chamber in the form of small droplets. Therefore, the scraper is used to squeeze out and scrape off the water so that the conical guide cavity and the spiral guide cavity only blow out air, avoiding water droplets falling on the product and affecting the color detection result.

[0017] Optionally, the water storage structure is arranged in the wrapping chamber; the water storage structure forms a water storage chamber having a first guide slope, a second guide slope and a support portion; the support portion forms a vertical surface abutting the purification structure; the first guide slope is connected to the side of the support portion away from the first filter net, and the second guide slope is connected to the side of the support portion close to the first filter net; wherein the second guide slope is connected to the vertical surface; the scraper is at least used to scrape water on the purification structure onto the second guide slope to allow the water to flow back to the water storage chamber.

[0018] By adopting the above-mentioned technical solution, the vertical surface is used to guide the purification structure, thereby increasing the sealing between the purification structure and the filter element, thereby preventing the air from directly entering the filter chamber without passing through the purification structure. The second guide slope is to allow the water on the purification structure to continue to contact the purification structure after being scraped off, thereby realizing the recycling of water.

[0019] Optionally, the water storage structure includes a plug-in component; a receiving groove is formed on the plug-in component; a socket is opened on the second guide slope, and the plug-in component is inserted into the socket so that the receiving groove is formed on the second guide slope; the plug-in component and the socket are detachably connected.

[0020] By adopting the above technical solution, a receiving groove is formed on the second guide slope, so after the dust and impurities scraped off by the scraper on the purification structure fall on the second guide slope, the dust and impurities fall on the second guide slope together with the water, and then the dust and impurities slide down the second guide slope together with the water, and move together to the receiving groove, as the water in the receiving groove gradually increases, it will overflow to the support part, and the dust and impurities will sink to the bottom of the receiving groove, so that the dust and impurities are collected in the receiving groove, thereby avoiding excessive adhesion of dust and impurities to the purification structure, affecting the effect of the purification structure on air purification and evaporation of water vapor. The plug-in component and the socket are detachably connected to facilitate the cleaning of dust and impurities.

[0021] Optionally, the air outlet structure includes: a pump body and an air outlet pipe body; the air outlet pipe body is inserted into the wrapping shell from bottom to top; the air outlet pipe body is used to form an air outlet cavity, and the air outlet cavity extends from bottom to top and then bends outward to below the liquid level of the water storage chamber; the pump body injects air into the air outlet cavity.

[0022] By adopting the above technical solution, the air will first be introduced into the water storage chamber below the liquid level, and then discharged from the water, thereby utilizing the water to purify the air.

[0023] Optionally, a first row of ports and a second row of ports are formed in the air outlet cavity; the first row of ports are located above the liquid level of the water storage chamber; and the second row of ports are located below the liquid level of the water storage chamber.

[0024] By adopting the above-mentioned technical scheme, part of the air is passed into the water storage chamber below the liquid level, and part of the air is passed into the purification structure. When the water is passed into the water storage chamber below the liquid level, bubbles are generated in the water in the water storage chamber, so that the water is easier to evaporate, thereby increasing the evaporation rate of the water, increasing the water vapor content in the air blown on the product, better reducing friction, preventing dust adhesion, and improving the accuracy of color detection.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The conical guide cavity is used to discharge the purified air to the product to be tested, which can clean the dust on the product to be tested, so that the color sensor can more accurately obtain the color of the product to be tested, and thus can more accurately display the color of the product to be tested; 2. The color sensor and / or color calibrator are installed inside the conical guide cavity. Then, the conical guide cavity can discharge purified air to form an air flow path that overlaps with the visual path of the color sensor and / or color calibrator to obtain the color of the product to be detected, so that the flow path formed by the purified air can fill the visual path for obtaining the color, thereby preventing excessive dust on the visual path from affecting the detection results; 3. The air flow speed in the spiral state will be greater than the air output from the conical guide cavity, which prevents external dust from entering the air output from the conical guide cavity, and better ensures that there is no dust on the visual path of the color detection to affect the accuracy of the detection.

[0028] The following is combined with Figure 1-26 This application is described in further detail.

[0029] The embodiment of the present application discloses a multifunctional color calibration system.

[0031] Refer to the attached pictures Figure 1 The support base 1 is used to place the product to be detected and the color card. The color sensor 11 is used to obtain the color of the product to be detected. The location of the color sensor 11 is shown in the attached figure. Fig.11 The color calibrator 12 is used to calibrate the color acquired by the color sensor 11. The display module 13 is used to display the color of the product to be detected after calibration. The color calibrator 12 calibrates the color acquired by the color sensor 11 according to the color card. The color calibrator 12 and the color sensor 11 are both prior art and will not be described.

[0032] Refer to the attached pictures Figure 6 , 11, the filter element 2 is a shell structure in this embodiment, and the filter element 2 forms a filter chamber 21 and an outlet 211 and a filter area 212 connected to the filter chamber 21. Preferably, the filter element 2 is a cylindrical shell of a regular polygon. The outlet 211 is the end face of the regular polygon, and the filter area 212 is the side face of the regular polygon. The filter area 212 is a mesh structure. The wind cleaning element 3 is arranged in the filter chamber 21, and the wind structure adopts a fan 31 in this embodiment, and preferably an axial flow fan. The wind structure sucks the air outside the filter area 212 into the filter chamber 21 inside the filter area 212. The guide member 4 forms a conical guide cavity and a spiral guide cavity at the outlet 211. The air in the filter chamber 21 will be discharged outward in the form of direct current wind when it is discharged outward from the conical guide cavity, forming a direct current wind flow channel. The air in the filter chamber 21 will be discharged outward in a spiral state when it is discharged outward from the spiral guide cavity, forming a spiral wind flow channel. In this embodiment, the guide member 4 includes a conical tube 41 and a spiral blade 42. The conical tube 41 forms a conical guide cavity, and the spiral blade 42 forms a spiral guide cavity. The conical tube 41 and the spiral blade 42 are both connected to the outlet 211. Preferably, the filter element 2 forms a circular tube 43 at the outlet 211, and the circular tube 43 is used to install the spiral blade 42 and the conical tube 41.

[0033] Refer to the attached pictures Fig.11 Specifically, the outlet 211 is provided with a mounting plate 44, a mounting ring 45 and a mounting frame 46, the mounting frame 46 is used to fix the mounting plate 44 and the mounting ring 45 to the inner wall surface of the outlet 211, the mounting frame 46 is a hollow frame, and the mounting plate 44 is located in the middle of the mounting ring 45. The color sensor 11 and / or the color calibrator 12 are installed in the conical flow guide cavity, preferably arranged in the middle of the mounting plate 44. The conical flow guide cavity is formed with a size smaller than the conical opening 411 of the color sensor 11 and / or the color calibrator 12, and the conical opening 411 and the middle of the mounting plate 44 are relatively matched. The conical tube 41 is fixedly mounted on the mounting ring 45. The spiral flow guide cavity is located at the edge of the conical flow guide cavity, that is, the spiral blade 42 is fixedly mounted on the mounting ring 45, the spiral blade 42 is connected to the gap between the mounting ring 45 and the outlet 211, and the conical tube 41 and the mounting ring 45 are connected to the gap between the mounting plate 44. The pneumatic dust cleaning component 3 is used to allow air to pass through the filter area 212, the filter chamber 21 and the outlet 211 in sequence and then be output to the outside through the conical guide cavity and the spiral guide cavity.

[0034] By adopting the above-mentioned technical scheme, the purified air discharged outwardly through the conical guide cavity is blown onto the product to be inspected, so that the dust on the product to be inspected can be cleaned and the color of the product to be inspected can be more accurately obtained. In addition, the color sensor 11 and / or the color calibrator 12 are installed inside the conical guide cavity. Then, it can be achieved that an air flow path formed by the conical guide cavity discharging the purified air outward will coincide with the visual path for the color sensor 11 and / or the color calibrator 12 to obtain the color of the product to be inspected, so that the flow path formed by the purified air can be filled in the visual path for obtaining the color, avoiding excessive dust on the visual path from affecting the detection result, so that even if it is used in dusty places, the accuracy of color detection can be well guaranteed. The spiral guide cavity will cause the air to be output in a spiral state, so the flow rate of the air in the spiral state will be greater than the air output outward from the conical guide cavity, so that the dust between the flow channel formed by the air output outward from the conical guide cavity and the air in the spiral state will move into the air in the spiral state under the action of pressure, thereby preventing external dust from entering the air output outward from the conical guide cavity, better ensuring that there is no dust on the visual path of color detection to affect the accuracy of detection, so that the color on the product can be detected more accurately.

[0035] In other embodiments, a purification structure 5 is provided on the filter area 212, and the purification structure 5 is a water-absorbing material. A water storage structure 6 is provided below the purification structure 5, and the purification structure 5 is partially located in the water storage structure 6. The purification structure 5 covers the filter area 212, and a plurality of filter holes are formed on the purification structure 5. The purification structure 5 adopts a sponge pad, and the sponge pad covers the filter area 212. The water storage structure 6 adopts a box body, and the water storage structure 6 is fixed below the filter element 2, wherein the below of the filter element 2 refers to the end of the filter element 2 away from the outlet 211. A plurality of openings are formed on the water storage structure 6, and a plurality of purification structures 5 are provided, which are respectively inserted into the plurality of openings, so that the purification structure 5 is in contact with water. By utilizing the water absorption of the purification structure 5, moisture will be present on the entire purification structure 5, so that when the air passes through the filter hole, the evaporation of water on the purification structure 5 can be promoted, so that the water vapor enters the filter chamber 21 together with the air. It plays a role in humidifying the surrounding environment, which is beneficial to improving the surrounding environment. In addition, water vapor can reduce static electricity in the air. Therefore, when the air containing water vapor is blown onto the product, it can also effectively generate static electricity on the product and better prevent dust adhesion.

[0036] In some other embodiments, referring to the accompanying drawings Figure 2-4 The outer part of the purification structure 5 is provided with a wrapping shell 7, and the wrapping shell 7 wraps the purification structure 5. The wrapping shell 7 forms an inlet 71 and a wrapping chamber 72 connected to the inlet 71, and the wrapping chamber 72 refers to Figure 7The purification structure 5 blocks the inlet 71, and an air outlet structure 8 is provided at the inlet 71, and the air outlet structure 8 is used to add external air into the wrapping chamber 72, so that the pressure in the wrapping chamber 72 is greater than the pressure in the filter chamber 21; the wrapping chamber 72 is connected to the filter chamber 21 through the filter hole and the filter area 212. By making the pressure in the wrapping chamber 72 greater than the pressure in the filter chamber 21, external air can enter the filter chamber 21 faster, thereby increasing the flow rate of the air discharged outward from the conical guide cavity and the spiral guide cavity. In a specific scheme of this embodiment, part of the purification structure 5 is located in the water storage structure 6, and the other part extends outward to form a first stop 57 and a second stop 58. The first stop 57 blocks the filter area 212, and the second stop 58 blocks the inlet 71. The inlet 71 is arranged at the bottom of the wrapping shell 7, and the bottom of the wrapping shell 7 is where the lower part of the filter element 2 is located. Then the first stop 57 and the second stop 58 are vertical or inclined. Thereby, the external air first passes through the second stop 58 to enter the wrapping chamber 72, and then passes through the first stop 57 and the filter area 212 to enter the filter chamber 21. Among them, the air outlet structure 8 adopts a fan in this embodiment, and preferably an axial flow fan is adopted.

[0037] In another specific embodiment, referring to the accompanying drawings Figure 11-13 , a first filter screen 22 and a second filter screen 23 are arranged at the filter area 212. Among them, a plurality of first filter screens 22 are arranged, and the first filter screen 22 is arranged on the side of the filter chamber 21. The second filter screen 23 is arranged on the bottom surface of the filter chamber 21. The side of the filter chamber 21 is perpendicular to the bottom surface of the filter chamber 21. The direction in which the external air enters the filter chamber 21 through the second filter screen 23 is the same as the direction in which the air is discharged from the outlet 211. The purpose is to use the air entering the second filter screen 23 to make the air in the filter chamber 21 be better discharged outward. More specifically, the wind cleaning part 3 includes a plurality of fans 31, which are distributed on the first filter screen 22 and the second filter screen 23. The fans 31 on the first filter screen 22 blow against each other, so that it is easy to form a wind with a small spiral state in the filter chamber 21, and then the fan 31 on the second filter screen 23 blows the air in the filter chamber 21 outward, which can speed up the speed of air discharge outward, and at the same time, it can better preserve the small spiral state.

[0038] In some other specific solutions, a third stopper 59 arranged at the second filter screen 23 is further formed on the purification structure 5 .

[0039] Refer to the attached pictures Figure 2-5, 25, in some other embodiments, a plurality of driving rollers 51 are provided in the wrapping chamber 72. The purification structure 5 is a flexible material, and the purification structure 5 is wound around the plurality of driving rollers 51. In this embodiment, the purification structure 5 may be a belt structure, and preferably a belt having water absorption is used. The plurality of driving rollers 51 are used to form a plurality of filtering planes 52 that partially match the first filter screen 22 with the purification structure 5, wherein the plurality of driving rollers 51 are arranged at the vertex of a regular polygon, so that the purification structure 5 between any two driving rollers 51 is parallel to one of the filter screens, and the surface of the purification structure 5 at this position is a filtering plane 52. A driving member 53 is provided on the driving roller 51, and the driving member 53 is used to drive the driving roller 51 to rotate, so that the purification structure 5 is externally driven by the plurality of first filter screens 22. The driving member 53 adopts a rotating motor, and the rotating motor is mounted on the filter element 2. The external transmission of the purification structure 5 in the plurality of first filter screens 22 is carried out by conveying and driving in the form of a conveyor belt. Preferably, the regular polygon is a decagon, and ten driving rollers 51 are provided. In some other specific solutions, twenty driving rollers 51 are provided, two driving rollers 51 form a group, and the two driving rollers 51 clamp the purification structure 5 to transport the purification structure 5, so as to avoid the situation where the purification structure 5 is wrapped around the driving roller 51 at a small angle and slips. The purification structure 5 will be driven outside the multiple first filter nets 22, so that different positions of the purification structure 5 can be in contact with the first filter nets 22 at different positions, so that the purification structure 5 can filter the air uniformly, thereby avoiding the situation where the purification structure 5 at one of the first filter nets 22 positions filters more dust outside, while the purification structure 5 at other first filter nets 22 positions filters less dust outside.

[0040] Refer to the attached pictures Figure 3-5, 21-22, in another specific scheme of the present embodiment, a scraper 54 is provided in the wrapping chamber 72, and the scraper 54 is used to abut against the filtering structure. The scraper 54 is two rods, and the scraper 54 forms a first abutting surface and a second abutting surface, one of the rods forms the first abutting surface, and the other rod forms the second abutting surface, and the filtering structure is located between the first abutting surface and the second abutting surface. One of the rods is fixed to the inner wall surface of the wrapping chamber 72, and the other rod is fixed to the filter element 2. The first abutting surface and the second abutting surface extend obtusely, and the first abutting surface and the second abutting surface both form an obtuse angle with the conveying direction of the filtering structure, so when the purification structure 5 is conveyed, the first abutting surface and the second abutting surface will exert a downward thrust on the water and impurities scraped off the purification structure 5, so that the water and dust impurities can be more easily moved from top to bottom and separated from the purification structure 5. The first abutting surface and the second abutting surface are symmetrically arranged relative to the filtering structure, and both the first abutting surface and the second abutting surface abut against the filtering plane 52. In this embodiment, if there is too much water on the purification structure 5, it is easy to cause water to enter the filtering chamber 21 in the form of small droplets, so that the scraper 54 is used to squeeze and scrape the water outward so that the conical guide cavity and the spiral guide cavity only blow out air, thereby preventing water droplets from falling on the product and affecting the color detection result.

[0041] Refer to the attached pictures Figure 5-6 In some other specific schemes, the regular polygon is a decagon, and ten installation areas are formed on the filter chamber 21. The installation area is the plane where the side of the decagon is located, and the first filter screen 22 is set in five installation areas, and the other five installation areas are set to form an installation plane 24. Among them, the first filter screen 22 is set by opening a hole on the filter element 2, and the installation surface is formed by the surface without opening a hole. One of the two rods of the scraper 54 is fixed on the installation surface, so that the scraper 54 is set in five groups, corresponding to five installation areas respectively. Then the position where the scraper 54 scrapes off water and dust impurities is not set with the first filter screen 22. Because the scraper 54 scrapes off water and dust impurities, it will cause more water and dust impurities to accumulate at the position where the scraper 54 contacts the purification structure 5, and as the accumulated water and dust impurities gradually increase, they will gradually scrape downwards. If the external air passes through the position where the scraper 54 contacts the purification structure 5 at this time, it is easy to take away part of the water and dust impurities, so it is difficult to effectively prevent water droplets from entering the filter chamber 21. Therefore, the scraper 54 of this solution is mainly used for the installation surface where the first filter screen 22 is not provided.

[0042] In some other embodiments, the water storage structure 6 is disposed in the wrapping chamber 72, and the water storage structure 6 forms a water storage chamber having a first guide slope 611, a second guide slope 621 and a support portion 63. The support portion 63 forms a vertical surface 622 abutting against the purification structure 5, the first guide slope 611 is connected to the side of the support portion 63 away from the first filter net 22, and the second guide slope 621 is connected to the side of the support portion 63 close to the first filter net 22. The second guide slope 621 is connected to the vertical surface 622; the scraper 54 is at least used to scrape the water on the purification structure 5 onto the second guide slope 621, so that the water flows back to the water storage chamber.

[0043] Refer to the attached pictures Figure 8-9 15. In a specific embodiment, the wrapping shell 7 is a shell with one end closed and the other end open, and the open port of the wrapping shell 7 is located at the bottom of the filter element 2. At this time, the water storage structure 6 is a base, and the base is inserted into the open port of the wrapping shell 7 to seal the wrapping chamber 72 in the wrapping shell 7. A first protrusion 61, a second protrusion 62, a support portion 63, a first bayonet 631, a second bayonet 632 and a circular groove 633 are formed on the base. Among them, the first bayonet 631 is tightly pressed against the wrapping shell 7, and the second bayonet 632 is tightly pressed against the filter element 2. Bolts are set at the first bayonet 631 and the second bayonet 632 to fix the base, the filter element 2 and the wrapping shell 7 together. The first protrusion 61 and the second protrusion 62 are both connected to the support part 63, and the support part 63 forms a bottom plane 634. The first protrusion 61 forms a first guide slope 611, and the second protrusion 62 forms a second guide slope 621, a vertical surface 622 and a circular groove 633. The vertical surface 622 contacts the purification structure 5, thereby guiding the purification structure 5. The purification structure 5 contacts the bottom plane 634 or there is a gap. The vertical surface 622 is mainly used to seal the bottom of the purification structure 5. The sealing of the vertical surface 622 and the purification structure 5 can prevent the air from directly passing over the purification structure 5 and reaching the filter chamber 21 under the purification structure 5. The circular groove 633 is used to accommodate the guide roller, and the circular groove 633 is a blind groove. The second guide slope 621 is to allow the water on the purification structure 5 to continue to contact the purification structure 5 after being scraped off, so as to realize the recycling of water. The scraper 54 is at least used to scrape the water on the purification structure 5 onto the second guide slope 621, so that the water flows back to the water storage chamber. Then the specific position of the scraper 54 is located above the second guide slope 621, that is, when observed from top to bottom, the scraper 54 and the second guide slope 621 overlap, and specifically the scraper 54 is located inside the second guide slope 621, so as to better ensure that the water falls on the second guide slope 621 and then enters the water storage chamber, thereby avoiding the situation where the water falls on the filter element 2. Among them, the water storage chamber is a chamber surrounded by the first guide slope 611, the bottom plane 634 and the vertical surface 622, and the second guide slope 621 is connected to the vertical surface 622.

[0044] Refer to the attached pictures Figure 22-24 In some other specific schemes, a third protrusion 73 is formed on the top surface of the wrapping shell 7, and the third protrusion 73 forms a surface abutting against the purification structure 5, thereby playing the same role as the vertical surface 622, so that the air in the wrapping chamber 72 can only pass through the purification structure 5 to enter the filter chamber 21.

[0045] Refer to the attached pictures Figure 6-7 In some other specific solutions, a plurality of slots 25 are formed on the edge of the filter element 2, and the slots 25 gradually become larger along the direction close to the filter element 2. A plurality of plug-in plates 26 are formed on the wrapping shell 7, and the plug-in plates 26 are inserted into the slots 25 to match the slots 25. This facilitates the installation of the wrapping shell 7 on the filter element 2, making the installation more stable.

[0046] Refer to the attached pictures Fig.10 , 16 -17, 20, in some other specific schemes, the water storage structure 6 includes a plug-in component 64, and the plug-in component 64 is a block. A receiving groove 641 is formed on the plug-in component 64. A socket 642 is provided on the second flow guide slope 621, and the plug-in component 64 is inserted into the socket 642 so that the receiving groove 641 is formed on the second flow guide slope 621. The plug-in component 64 and the socket 642 are detachably connected, wherein the detachable connection is a tight fit, or a bolt connection. Preferably, the plug-in structure is an annular block, and the receiving groove 641 is an annular blind groove. The second guide slope 621 forms a receiving groove 641. After the dust and impurities scraped off by the scraper 54 on the purification structure 5 fall on the second guide slope 621, the dust and impurities fall on the second guide slope 621 together with the water, and then the dust and impurities slide down the second guide slope 621 together with the water, and move together to the receiving groove 641. As the water in the receiving groove 641 gradually increases, it will overflow to the support part 63, and the dust and impurities will sink to the bottom of the receiving groove 641, so that the dust and impurities are collected in the receiving groove 641, so as to avoid excessive adhesion of dust and impurities to the purification structure 5, affecting the effect of the purification structure 5 on air purification and evaporation of water vapor. The plug-in component 64 is detachably connected to the socket 642 to facilitate the cleaning of dust and impurities.

[0047] Refer to the attached pictures Fig.10 , 16-19, in another specific solution of the plug-in component 64, a vertical rod 643 and a fixing plate 644 are arranged in the receiving groove 641, the vertical rod 643 is fixed to the plug-in component 64, the fixing plate 644 is fixed to the vertical rod 643, and the vertical rod 643 makes the fixing plate 644 located above the receiving groove 641. A recessed groove 645 is formed in the fixing plate 644, and the recessed groove 645 is larger than the receiving groove 641, that is, when viewed from top to bottom, the recessed groove 645 completely covers the receiving groove 641. The concave groove 645 is provided with an inner groove 646 near the edge of the first guide slope 611, and the inner groove 646 is connected to the concave groove 645. The dust impurities in the water, whose density is greater than that of water, can fall into the receiving groove 641, and the dust impurities, whose density is less than that of water, will float to the concave groove 645 when the water passes through the area between the receiving groove 641 and the concave groove 645, and then enter the inner groove 646. The inner groove 646 is concave upward, so that the dust impurities with a density less than that of water can be better collected. Specifically, the scraper 54 will scrape the water off all the time, and the water will flow through the second guide slope 621 all the time. When the water flows through the second guide slope 621, the water level can be higher than the bottom surface of the inner groove 646.

[0048] Refer to the attached pictures Figure 13-14 26. In some other embodiments, the air outlet structure 8 includes: a pump body and an air outlet pipe body 81. The air outlet pipe body 81 is inserted into the wrapping shell 7 from bottom to top. The air outlet pipe body 81 is used to form an air outlet cavity, which extends from bottom to top and then bends outward to below the liquid level of the water storage chamber. The pump body injects air into the air outlet cavity. The pump body adopts an air pump. The air will first pass into the water below the liquid level of the water storage chamber, and then be discharged from the water to the outside, thereby using water to purify the air. The dust impurities in the air can be better reduced, but because air is added to the water, bubbles will be generated in the water, and the air pump adds external air very quickly, so some air will not contact the water and will be directly discharged outward along the bubbles, so that the water only purifies part of the air, so the bubbles will increase the speed of water vapor generation and the effect of air filtration is better.

[0049] In other embodiments, the air outlet cavity forms a first row of ports 811 and a second row of ports 812; the first row of ports 811 is located above the liquid level of the water storage chamber; the second row of ports 812 is located below the liquid level of the water storage chamber. Part of the air is passed into the water storage chamber below the liquid level, and part is passed into the purification structure 5.

Alternatively, the connection pipe body 83 is used to connect the connection chamber with the area between the purification structure 5 and the first filter screen 22.

[0051] Refer to the attached pictures Figure 4-5 25. In some specific embodiments, the driving member 53 includes a motor, and a plurality of transmission belts 55 and pulleys 56.
