[0052] Please refer to Figures 1-4 The embodiment of the present application provides an embedded air purification equipment 1 for purifying indoor air by embedding on the ceiling, and introducing outdoor fresh air into the indoor in time after purification, while improving the freshness and cleanliness of indoor air. The embedded air purification equipment 1 comprises a host and a filter screen replacement push rod 11, and the filter screen replacement push rod 11 is used for replacing the filter screen of the host.

[0053] Among them, the host comprises a shell 12, a mounting body 13, a fan 14 and a filter screen body 15, the inside of the shell 12 has a cavity, the shell 12 can be composed of an upper shell 121 and a lower shell 122, and the upper shell 121 and the lower shell 122 define the cavity. The mounting body 13 and the fan 14 are placed in the cavity, and the mounting body 13 is provided with a mounting position s (as shown in Figure 4 In the mounting position s, when the fan 14 is placed on the mounting position s, the mounting body 13 defines an air inlet channel a (as shown in Figure 4 and an air outlet channel b (as shown in Figure 4As shown in Figure b), the filter body 15 and the mounting body 13 are detachably connected in the air inlet channel a. By reserving a mounting position s on the mounting body 13, the mounting position s separates the channel of the mounting body 13. When the fan 14 is installed, the fan 14 just divides the channel into the air inlet channel a and the air outlet channel b. Therefore, there is no need to set up an additional air duct for air extraction and supply. That is, the structure of the mounting body 13 is reused, which can reduce the volume occupied and greatly improve the internal space utilization of the embedded air purification device 1.

[0054] Please refer to the details. Figure 3 As shown, a light 1221 can be installed on the lower housing 122. The light 1221 is activated when the embedded air purifier 1 enters the working state and / or when the filter body 15 is replaced, which can serve as an illumination reminder. In addition, an air inlet hole 1222 is provided on the lower housing 122 at the position corresponding to the air inlet channel a, and an air outlet hole 1223 is provided at the position corresponding to the air outlet channel b.

[0055] Please refer to the details. Figure 3 As shown, to further enhance the air filtration effect, an ultraviolet lamp 1224 can be installed in the air intake channel a.

[0056] Please continue to combine Figure 3 and Figure 4 As shown, specifically, the fan 14 can be a fan that draws air from the bottom and supplies air from the side. When the fan 14 is placed in the installation position s, the air inlet on the bottom of the fan 14 and the installation body 13 form an air inlet channel a, and the air outlet on the side of the fan 14 and the installation body 13 form an air outlet channel b.

[0057] Specifically, the mounting body 13 can be formed by splicing an upper body 131 and a lower body 132. The splicing of the upper body 131 and the lower body 132 defines a channel, and an installation position s is reserved in the channel.

[0058] Please see Figure 3 , Figure 5 and Figure 6 As shown in the illustration, in one embodiment, a first positioning member 151 is provided on the filter body 15, and a second positioning member 133 is provided on the mounting body 13 at the position corresponding to the first positioning member 151. When the filter body 15 is subjected to external force, the first positioning member 151 and the second positioning member 133 are locked or disengaged. This arrangement ensures that when replacing the filter body 15, the operator only needs to apply a certain force to the filter body 15 to lock or disengage the first positioning member 151 and the second positioning member 133, thus achieving the installation and removal of the filter body 15. This operation is convenient, saves effort, and greatly improves the user experience.

[0059] Optionally, one of the first positioning member 151 and the second positioning member 133 is a positioning column, and the other is a positioning portion which accommodates the positioning column and cooperates with the positioning column. The present application does not make specific limitation on this, as long as the first positioning member 151 and the second positioning member 133 can be locked or disengaged when a certain force is applied to the filter screen body 15.

[0060] For the convenience of understanding, in the embodiment of the present application, the first positioning member 151 is taken as the positioning column, and the second positioning member 133 is taken as the positioning portion, which should not be regarded as a limitation on the present application.

[0061] More specifically, as shown in Figure 5 and Figure 6 , as an optional embodiment, the positioning column is provided with a hook member 1511, and the positioning portion includes a fastening groove 1331 and two symmetrical fixing members 1332, the fixing member 1332 is partially arranged in the fastening groove 1331, and the fixing member 1332 is provided with an arc hook member 1333 on one side adjacent to the other side, the hook member 1511 and the arc hook member 1333 are structurally matched, when a certain force is applied to the filter screen body 15 for the first time, the hook member 1511 of the positioning column is arranged between the arc hook members 1333 of the two fixing members 1332 of the positioning portion, and the fixing member 1332 is partially arranged in the fastening groove 1331, so that the arc hook member 1333 clamps and fixes the hook member 1511, thereby locking the positioning column and the positioning portion; when a certain force is applied to the filter screen body 15 for the second time, the arc hook member 1333 clamps the hook member 1511 and exits from the fastening groove 1331, and then the arc hook member 1333 releases the hook member 1511, thereby disengaging the positioning column and the positioning portion. Such a setting can make the positioning column and the positioning portion closely fit when locked, which is more firm and avoids rebound, thereby ensuring the stability of the installation of the filter screen body 15.

[0062] Please refer to Figures 1-3 , and Figure 7 , as an embodiment, the shell 12 is provided with a hatch 123 corresponding to the position of the filter screen body 15, and in the embodiment of the present application, the hatch 123 is arranged on the lower shell 122. The hatch 123 is provided with a hatch cover 124, one side of the hatch cover 124 is hinged to the shell 12, and the other side is detachably connected to the shell 12. By opening the hatch cover 124, the filter screen body 15 can be disassembled and replaced through the exposed hatch 123. Optionally, the other side of the hatch cover 124 can be connected to the shell 12 in a magnetic connection manner, or in the same connection manner as the positioning column and the positioning portion of the filter screen body 15 and the installation body 13, and the specific connection manner can be referred to the first positioning member 151 on the filter screen body 15 and the second positioning member 133 on the installation body 13, which will not be described herein again.

[0063] Please refer to Figure 1 and Figure 3Further, the embedded air purification device 1 further comprises a collecting bag 16 detachably connected with the shell 12, when the collecting bag 16 is connected with the shell 12 and the first positioning member 151 is disengaged from the second positioning member 133, the filter screen body 15 falls and is accommodated in the collecting bag 16, and the collecting bag 16 is contracted and tightly wrapped around the filter screen body 15 under the action of the fan 14. Through the above arrangement, firstly, dust on the surface of the filter screen body 15 can be prevented from flying and choking the replacement personnel, and secondly, the replacement personnel can be prevented from being infected by pollutants such as bacteria and viruses accumulated on the surface of the filter screen body 15, thereby greatly improving the safety of replacement of the filter screen body 15.

[0064] As shown in Figure 3 , Figures 7-9 , specifically, the collecting bag 16 comprises a support frame 161 and a bag 162, the opening end of the bag 162 is fixed on the support frame 161, and the support frame 161 is provided with a knob device 163, the knob device 163 comprises a base 1631, and the base 1631 is provided with a flat cutting edge c and a convex edge d.

[0065] As shown in Figure 10 and Figure 11 , when the convex edge d is rotated to the inside of the support frame 161 under the action of external force, the convex edge d is closer to the central axis position than the inside of the support frame 161, at this time, the convex edge d limits the falling of the filter screen body 15, and the filter screen body 15 can be further fixed, so as to avoid the vibration caused by the working of the fan 14 from causing the filter screen body 15 to fall out of the device.

[0066] As shown in Figure 12 and Figure 13 , when the flat cutting edge c is rotated to the inside of the support frame 161 under the action of external force, the flat cutting edge c is flush with the inside of the support frame 161, or the projection of the flat cutting edge c and the inside of the support frame 161 does not overlap, at this time, the natural falling of the filter screen body 15 will not be limited, and the replacement personnel can first rotate the flat cutting edge c to the inside of the support frame 161, and then replace the filter screen body 15, which is convenient, fast and simple to operate.

[0067] As shown in Figure 14 and Figure 15As shown, further, the knob device 163 further comprises a rotating buckle 1632 and a limiting piece 1633, the rotating buckle 1632 is fixed on the base 1631, the rotating buckle 1632 extends along the direction of the flat cut edge c and beyond the flat cut edge c, when the knob device 163 is subjected to an external force to make the flat cut edge c rotate to the inside of the support frame 161, the rotating buckle 1632 ejects the filter screen body 15 so as to drop the filter screen body 15 into the collecting bag 16, which can avoid the filter screen body 15 being stuck in the installation body 13 and being dropped unnaturally during replacement, further accelerating the efficiency of the replacement personnel replacing the filter screen body 15. The limiting piece 1633 is arranged between the base 1631 and the rotating buckle 1632, the base 1631 is provided with a protrusion 16311, the limiting piece 1633 is provided with an annular groove 16331 corresponding to the position of the protrusion 16311, when the base 1631 rotates, the protrusion 16311 moves in the annular groove 16331 and is limited in the annular groove 16331. By arranging the limiting piece 1633, the base 1631 can be limited to move through the annular groove 16331, which avoids the base 1631 from being damaged due to excessive rotation and improves the service life of the knob device 163.

[0068] In order to facilitate the understanding of the replacement process of the filter screen body 15, the specific structure of the filter screen replacement push rod 11 is described in the embodiment of the present application. Figure 16 and Figure 17 As an embodiment, the filter screen replacement push rod 11 comprises a rod body 111, a lifting block 112, an elastic piece 113 and a replacement piece 114, the rod body 111 is connected with the lifting block 112 through the replacement piece 114, and the length of the rod body 111 is not limited in the present application. The elastic piece 113 can be a spring, the elastic piece 113 is sleeved on the outer circumferential side of the rod body 111 and arranged between the rod body 111 and the replacement piece 114, and the replacement piece 114 is specifically a U-shaped piece. When the filter screen body 15 is replaced, the replacement piece 114 abuts against the shell 12, at this time the replacement personnel only needs to exert a force on the rod body 111, the lifting block 112 will press the filter screen body 15 to be replaced until the first positioning piece 151 and the second positioning piece 133 are disengaged, and the filter screen body 15 is automatically dropped by using the weight of the filter screen body 15. Then, a new filter screen body 15 is placed in the U-shaped groove of the replacement piece 114, and the replacement piece 114 abuts against the shell 12 again. At this time, the replacement personnel only needs to exert a force on the filter screen body 15 through the rod body 111, and the lifting block 112 will lift the filter screen body 15 until the first positioning piece 151 and the second positioning piece 133 are locked, thereby completing the replacement of the filter screen body 15. Under the action of the elastic piece 113, the filter screen replacement push rod 11 returns to the normal state. By using the filter screen replacement push rod 11, a ladder is not needed, and the replacement of the filter screen body 15 can be completed by using the weight of the filter screen body 15 to automatically drop and the lifting action of the filter screen replacement push rod 11 on the filter screen body 15, which is convenient and fast and improves the efficiency of the replacement personnel replacing the filter screen body 15.

[0069] Specifically, fasteners 1141 can be installed on the two U-shaped groove walls of the replacement part 114. When a new filter body 15 is placed in the U-shaped groove of the replacement part 114, the fasteners 1141 can maintain the stability of the filter body 15 and prevent the filter body 15 from falling off during the replacement process.

[0070] like Figure 18 As shown, furthermore, notches 1142 for clamping bags 162 are provided on the two U-shaped groove walls of the replacement component 114. In this embodiment of the invention, notches 1142 are provided on both U-shaped groove walls of the replacement component 114. The notches 1142 extend in a direction parallel to the U-shaped groove walls of the replacement component 114, and the width of the notches 1142 gradually narrows along the extension direction. By providing notches 1142 for clamping bags 162 on the two U-shaped groove walls of the replacement component 114, after the filter body 15 falls and is collected in the collection bag 16, the collection bag 16 shrinks under the action of the fan and wraps tightly against the filter body 15. At this time, the bag 162 can be recycled together with the filter body 15 by clamping the shrinking bag 162 through the notches 1142 of the replacement component 114. This is convenient and hygienic, and greatly improves the user experience of the embedded air purification device 1.

[0071] Please continue reading. Figures 14-16 As shown, the base 1631 is further provided with a rotating groove 16312. In this embodiment of the invention, the rotating groove 16312 is located on the opposite side of the protrusion 16311. The replacement part 114 is provided with a rotating control part 1143 that cooperates with the rotating groove 16312. The rotating control part 1143 can be inserted into the rotating groove 16312 to control the rotation of the base 1631. By providing the rotating control part 1143 on the replacement part 114, the replacement personnel can stand on the ground and control the rotation of the base 1631 without a ladder, so that the flat cut edge c rotates to the inside of the support frame 161, thereby causing the filter body 15 to fall into the collection bag 16, thus completing the disassembly of the filter body 15; or after replacing with a new filter body 15, controlling the rotation of the base 1631 causes the protruding edge d to rotate to the inside of the support frame 161, thereby preventing the filter body 15 from falling off.

[0072] In summary, the filter replacement push rod 11 has a reusable structure. It can rotate the base 1631 via the rotation control component 1143 to detach the filter body 15, support the filter body 15 for replacement, and collect the bag 162 and the filter body 15 together through the notch 1142. This makes the filter replacement push rod 11 functionally diverse and highly practical.
