DETAILED DESCRIPTION

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0023] Example 1

[0024] This is the first embodiment of the present invention, which provides a photocatalytic air purification device based on air flow field.

[0025] Specifically, refer to Figure 1 , Figure 2 , a photocatalytic air purification device based on air flow field, comprising a main assembly 100, including a shell 101, an air inlet 102 arranged on the outer wall of the shell 101, an air outlet 103 and a wind frame 104 arranged on the inner wall of the shell 101; The adjustment component 200 includes a fan 201 and a mounting shell 202 installed inside the housing 101. The mounting shell 202 is provided with a moving part inside. The moving part is connected to the fan 201 and driven by the fan 201. The fan 201 is affected by the monitoring data of the laser dust sensor in the housing 101 and performs gear adjustment. When the monitoring data is normal, the fan 201 rotates normally and the moving parts do not move. When the monitoring data is abnormal, the fan 201 is raised in gear. At this time, the moving parts are driven by the fan 201 to move inside the mounting shell 202. When the moving parts move, they drive the guide plate 1041 inside the wind frame 104 to move, thereby changing the wind direction generated by the fan 201. At the same time, the adjusting parts located inside the outer shell 101 are driven by the moving parts to change the purification channel of the air circulation inside the outer shell 101.

[0026] Among them, the fan 201 is located at the position of the air inlet 102. Through the rotation of the fan 201, the air in the space is blown into the interior of the purification device. An array of multiple guide plates 1041 are installed inside the wind frame 104. The guide plates 1041 control the wind direction of the fan 201 blowing into the interior of the purification device, and finally blown out through the air outlet 103 after purification.

[0027] The dust level in the space is detected by a laser dust sensor, and the rotation speed of the fan 201 is affected by the data detected by the laser dust sensor. When it is detected that the dust level in the space is low, the rotation speed of the fan 201 is slow, and the wind force blowing into the interior of the purification device is small. At the same time, the guide plate 1041 does not move, and the wind direction generated by the fan 201 does not move, and it is directly blown into the interior of the purification device and discharged from the device through the air outlet 103.

[0028] When a high dust level is detected in the space, the speed of the fan 201 increases, and the moving parts inside the mounting shell 202 move due to the rotation of the fan 201. The moving parts are directly connected to the guide plate 1041 inside the wind frame 104 and change the state of the guide plate 1041, so that the guide plate 1041 reciprocates inside the wind frame 104 to change the direction of the wind blown by the fan 201.

[0029] When the wind generated by the fan 201 passes through the guide plate 1041, it is affected by the guide plate 1041 and blows up and down in a circular motion when passing through the wind frame 104, so that the wind enters the interior of the purification device evenly, allowing the air to contact the photocatalyst evenly, thereby improving the overall utilization rate of the photocatalyst by changing the air direction.

[0030] At the same time, the adjusting component is driven by the moving component, so that the position of the photocatalyst inside the purification device changes. By changing the position of the photocatalyst, the time for air to pass through the photocatalyst layer is changed, thereby improving the efficiency of dust adsorption and decomposition of other pollutants.

[0031] Example 2

[0032] This is the second embodiment of the present invention, which is implemented based on the previous embodiment.

[0033] Specifically, refer to Figure 3~Figure 5 The moving parts include a worm gear 203, which is meshed with a worm 2011 at the axis of the fan 201 and rotates synchronously with the fan 201. A transmission shaft 2031 is provided at the axis of the worm gear 203 and a transmission plate 2032 is provided at the end of the transmission shaft 2031. A movable rod 2033 is provided in an array on the end surface of the transmission plate 2032. A first elastic member 2034 is connected to the end of the movable rod 2033 and the other end of the first elastic member 2034 is fixed to the end surface of the transmission plate 2032 and pulls the movable rod 2033 inward.

[0034] Among them, the worm 2011 at the axis of the fan 201 drives the worm wheel 203 to rotate inside the mounting shell 202, and the transmission shaft 2031 at the axis of the worm wheel 203 is synchronized with the rotation speed of the worm 2011. When the rotation speed of the fan 201 is slow, the rotation speed of the worm 2011 is slow, and the transmission shaft 2031 with synchronous rotation speed drives the transmission plate 2032 to rotate. The movable rod 2033 on the surface of the transmission plate 2032 is pulled by the first elastic member 2034, and the end of the movable rod 2033 moves toward the direction of the transmission shaft 2031.

[0035] When the speed of the fan 201 is high, the speed of the transmission shaft 2031 also increases synchronously, and the movable rod 2033 rotates with the transmission plate 2032 , and the end of the movable rod 2033 moves outward under the influence of centrifugal force.

[0036] Preferably, refer to Figure 5 The outer wall of the transmission plate 2032 is provided with a transmission ring 204 and the inner wall array of the transmission ring 204 is provided with a slot 2041. The transmission plate 2032 rotates inside the transmission ring 204 and the end of the movable rod 2033 is engaged in the slot 2041 and drives the transmission ring 204 to rotate.

[0037] The transmission plate 2032 is arranged inside the transmission ring 204 and is not connected to the transmission ring 204 . After the movable rod 2033 on the surface of the transmission plate 2032 moves outward and engages in the slot 2041 on the surface of the transmission ring 204 , the transmission ring 204 rotates together with the transmission plate 2032 .

[0038] A fixed shell 205 is disposed inside the mounting shell 202 . An output gear 206 is disposed at the end of the fixed shell 205 and the output gear 206 meshes with a transmission gear 2042 on the outer wall of the transmission ring 204 . The output gear 206 rotates synchronously with the transmission ring 204 .

[0039] The transmission gear 2042 is fixed to the lower surface of the transmission ring 204 and rotates together with the transmission ring 204 . The transmission gear 2042 is meshed with the output gear 206 . The output gear 206 is relatively large and its rotation speed is much slower than that of the transmission gear 2042 .

[0040] Reference Figure 3 , Figure 4 An output shaft 2061 is provided at the end of the output gear 206, and the end of the output shaft 2061 extends to the interior of the fixed shell 205 and is connected to a movable column 2062. A cylinder 2064 is also provided inside the fixed shell 205, and a straight rod 2065 is provided at the end of the cylinder 2064. A sliding column 2066 is provided at the end of the straight rod 2065. The end of the sliding column 2066 extends to the inner wall of the curved groove 2063 opened on the outer wall of the movable column 2062 and slides with it. When the cylinder 2064 rotates on the surface of the movable column 2062 through the sliding column 2066, it reciprocates inside the fixed shell 205.

[0041] Among them, the fixed shell 205 is fixed inside the mounting shell 202, and the output gear 206 is connected to the internal movable column 2062 through the output shaft 2061. When the output gear 206 rotates, the movable column 2062 inside the fixed shell 205 rotates together. At the same time, the cylinder 2064 is restricted by the limiting groove on the surface of the cylinder 2064, so that the cylinder 2064 cannot rotate. The sliding column 2066 slides in the curved groove 2063 on the surface of the movable column 2062, so that the cylinder 2064 moves back and forth up and down inside the fixed shell 205.

[0042] In addition, a second elastic member 2067 is disposed on the surface of the cylinder 2064 . When the movable rod 2033 is not engaged with the locking groove 2041 , the cylinder 2064 is pushed downwardly of the fixed shell 205 by the second elastic member 2067 .

[0043] Preferably, a hinged plate 2068 is connected to the end of the cylinder 2064, and the outer wall of the hinged plate 2068 is hinged to the guide plate 1041 arranged on the inner wall of the wind frame 104. The guide plate 1041 is driven by the hinged plate 2068 to reciprocate inside the wind frame 104 and change the wind direction blown by the fan 201 to the wind frame 104.

[0044] Among them, the hinged plate 2068 is connected to the bottom of the cylinder 2064. As the cylinder 2064 moves up and down inside the fixed shell 205, the hinged plate 2068 moves up and down synchronously outside the fixed shell 205 and drives the hinged guide plate 1041 to flip back and forth inside the wind frame 104, thereby changing the wind direction of the wind blown inward by the fan 201, so that the wind enters the interior of the purification device evenly and contacts the photocatalyst in the purification device evenly, avoiding the problem of low efficiency of the photocatalyst caused by a single wind direction.

[0045] In summary, when in use, the dust level in the space is detected by a laser dust sensor. When the dust level is low, the speed of the fan 201 is normal, and the air is blown to the inside of the purification device through the air inlet 102, driving the air to pass through the photocatalyst. At this time, the air can pass through the device faster, and equipment such as the fan 201 does not need to run at high load for a long time. When the dust level is high, the speed of the fan 201 increases, and the worm 2011 drives the worm gear 203 to rotate rapidly. When the worm gear 203 rotates at high speed, the transmission shaft 2031 drives the transmission plate 2032 to rotate rapidly inside the transmission ring 204. The movable rod 2033 on the surface of the transmission plate 2032 moves outward under the influence of the centrifugal force when the transmission plate 2032 rotates, and the end of the movable rod 2033 is engaged in the slot 2041 on the surface of the transmission ring 204 and drives the transmission ring 204 to rotate.

[0046] The output gear 206 is driven to rotate by the rotation of the transmission ring 204, and the movable column 2062 inside the fixed shell 205 rotates with the output gear 206, and the sliding column 2066 on the surface of the straight rod 2065 slides inside the curved groove 2063. When the movable column 2062 rotates, the cylinder 2064 is driven by the straight rod 2065 to move up and down inside the fixed shell 205, thereby causing the hinged plate 2068 to move up and down outside the fixed shell 205. The guide plate 1041 hinged on the surface of the hinged plate 2068 is driven by the hinged plate 2068 to move inside the wind frame 104, thereby changing the flow direction of the air. The air is deflected through the guide plate 1041 and flows to the photocatalytic area that was originally not fully utilized, thereby increasing the contact area between the air and the photocatalyst and improving the utilization rate of the photocatalyst.

[0047] Example 3

[0048] This is the third embodiment of the present invention, which is implemented based on the previous embodiment.

[0049] Specifically, refer to Figure 3 , Figure 5 The adjusting component includes a rack 207 and the rack 207 is meshed with the output gear 206. A connecting column 2071 is arranged on the outer wall of the rack 207 and a third elastic member 2072 is sleeved on the outer wall of the connecting column 2071. A movable tooth 2073 is movably arranged on the other end of the connecting column 2071.

[0050] Among them, refer to Figure 5 The movable tooth 2073 is sleeved on the outside of the connecting column 2071 and is pushed by the third elastic member 2072, so that the movable tooth 2073 is away from the rack 207 when the output gear 206 is not rotating. When the output gear 206 rotates, the rack 207 moves outward, and at the same time, the state of the rack 207 is maintained by the engagement of the movable tooth 2073 with the output gear 206.

[0051] Preferably, the other end of the rack 207 is connected to the first connecting rod 2074 and the other end of the first connecting rod 2074 is connected to the second connecting rod 208. The end of the second connecting rod 208 is connected to the first connecting plate 2075 at the end of the first connecting rod 2074 and moves along the arc groove 2076 opened on the end surface of the first connecting plate 2075.

[0052] Among them, refer to Figure 7 The first connecting rod 2074 extends to the outside of the fixed shell 205, and the first connecting plate 2075 is installed at the tail end of the first connecting rod 2074. The arc groove 2076 on the surface is a connected parallel groove. The end of the second connecting rod 208 is initially engaged in the bottom part of the arc groove 2076. When the first connecting rod 2074 is pushed by the rack 207 to move, the end of the second connecting rod 208 slides from the bottom part of the arc groove 2076 to the top part, and the second connecting rod 208 moves upward.

[0053] Preferably, the other end of the second connecting rod 208 is connected to the second connecting plate 209 and the end surface of the second connecting plate 209 is provided with an inclined groove 2091, and the second connecting plate 209 is driven to move by the movement of the second connecting rod 208 on the surface of the first connecting plate 2075, and a third connecting rod 2092 is also provided at the end of the second connecting plate 209.

[0054] Among them, the other end of the second connecting rod 208 is engaged into the inclined groove 2091 on the surface of the second connecting plate 209. When the end of the second connecting rod 208 slides from the bottom to the top in the arc groove 2076 on the surface of the first connecting plate 2075, the other end of the second connecting rod 208 slides from low to high in the inclined groove 2091 and drives the third connecting rod 2092 to move. Through the movement of the third connecting rod 2092, the position of the photocatalyst inside the purification device is changed, and then the shape of the air flow channel formed by the photocatalyst layer inside the purification device is changed, and the time for the air to flow inside the flow channel is changed, thereby increasing the contact time between the air and the photocatalyst, and improving the dust adsorption and decomposition efficiency of other pollutants.

[0055] Example 4

[0056] Reference Figure 6~Figure 8 , which is the fourth embodiment of the present invention, and this embodiment provides a catalytic module.

[0057] Specifically, the purification component 400 includes a catalytic module 401, a clamping plate 402 is clamped at the end of the catalytic module 401, and an adjusting gear 403 is provided at the end of the clamping plate 402; An elliptical plate 301 is disposed at the end of the catalytic module 401 , a moving tooth 302 is disposed on the inner wall of the elliptical plate 301 , and a push rod 303 is disposed on the outer wall of the elliptical plate 301 .

[0058] Among them, the catalytic module 401 is connected to the adjusting gear 403 through the clamping plate 402, the adjusting gear 403 is meshed with the moving teeth 302 inside the elliptical plate 301, the moving teeth 302 are separated and fixed inside the elliptical plate 301, and the push rod 303 on the surface of the elliptical plate 301 is located in the slope 2093 on the surface of the third connecting rod 2092. When the third connecting rod 2092 moves, the elliptical plate 301 moves laterally through the slope 2093, and the insertion rod 304 at the other end of the elliptical plate 301 squeezes the fourth elastic member 305 when it moves.

[0059] The lateral movement of the elliptical plate 301 causes the adjusting gear 403 to rotate, and the separated moving teeth 302 cause the adjusting gears 403 to rotate in pairs. The catalytic module 401 changes its posture along with the rotation of the adjusting gear 403. Fig. 9 As shown, the catalytic module 401 changes its arrangement from the original parallel arrangement. At this time, the wind blown by the fan 201 will change the residence time of the air in the catalyst area when passing through the catalytic module 401, thereby improving the efficiency of dust adsorption and decomposition of other pollutants.
