Description

Technical Field

[0001] The present invention relates to the technical field of fresh air equipment, and in particular to a fresh air replacement filter structure and an intelligent fresh air replacement device. Background Art

[0002] The fresh air filter device is a device that exchanges and filters indoor and outdoor air. The device is mainly composed of a fan, an air inlet, an air outlet, a filter element, and various pipes and joints. The filter element is an important component of the fresh air filter device. As the filter element filters more air, a large amount of dirt will adhere to the surface. Therefore, it is necessary to replace the filter structure and clean the impurities on the filter element after the filter element has been used for a period of time.

[0003] At present, in the prior art, the filter element is generally fixed on the inner surface of the shell. The incoming air can be filtered by installing the shell in the fresh air device. However, the position of the filter element is fixed, and the filtering effect of the air entering the body is consistent, while the quality of the outside air often changes. When the quality of the outside air is poor, the incoming air needs to be filtered more strongly. When the quality of the outside air is high, the flow output of the filtered air needs to be accelerated. Therefore, the present invention proposes a fresh air replacement filter structure and an intelligent fresh air replacement device. Summary of the invention

[0004] The main purpose of the present invention is to provide a fresh air replacement filter structure and an intelligent fresh air replacement device, which can solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the fresh air replacement filter structure proposed in the present invention includes a shell, the inner surface of which is rotatably connected to a filter element, an adjustment component and an auxiliary cleaning component are arranged inside the shell, and a pull rope is fixedly connected to the outer wall of the shell.

[0006] Preferably, the adjustment component includes an electric telescopic rod, which is embedded in the shell, the telescopic end of the electric telescopic rod is fixedly connected to a connecting block, the bottom of the connecting block is fixedly connected to a vertical rod, and a small round rod is fixedly connected to the outer wall of the vertical rod.

[0007] Preferably, the filter element is penetrated by a rotating shaft and fixedly connected to the rotating shaft, both ends of the rotating shaft are fixedly connected with a disc, the outer wall of the disc is fixedly connected with a straight rod, the outer wall of the straight rod is provided with a straight slot, the small round rod is slidably connected in the straight slot, the telescopic end of the electric telescopic rod is extended, the connecting block drives the vertical rod to move, the small round rod slides in the straight slot, the straight rod drives the disc to rotate, and the rotating shaft drives the filter element to rotate, thereby adjusting the angle of the filter element.

[0008] Preferably, the small round rods and the round discs are both provided in multiple groups, and the number of groups of the small round rods and the number of groups of the round discs are equal.

[0009] Preferably, one end of the straight rod away from the disc is rotatably connected to a rotating wheel.

[0010] Preferably, the auxiliary cleaning component includes an air bin, which is fixedly connected to the inner wall of the shell, and a one-way air outlet and a one-way air inlet are provided on the outer wall of the air bin. The piston in the inner wall of the air bin is connected to a piston plate, and a connecting rod is fixedly connected to the outer wall of the piston plate, and the end of the connecting rod away from the piston plate is fixedly connected to a pressure plate.

[0011] Preferably, the pressure plate is elastically connected to the outer wall of the air bin via a connecting spring, and the pressure plate is brought into contact with the rotating wheel through the reset action of the connecting spring. The straight rod drives the disc to reciprocate through the continuous extension and retraction of the telescopic end of the electric telescopic rod. Under the reset action of the connecting spring, the pressure plate drives the connecting rod to reciprocate, so that the piston plate reciprocates in the air bin. When the piston plate moves toward the pressure plate, the one-way air inlet can suck the filtered air into the air bin, and when the piston plate moves away from the pressure plate, the gas in the air bin is ejected through the one-way air outlet, so as to clean the filter element.

[0012] Preferably, a placement groove is provided inside the filter element, and an elastic bag is embedded in the placement groove. The elastic bag is connected to an air inlet pipe and an air outlet pipe, and the diameter of the air inlet pipe is larger than the diameter of the air outlet pipe. Through the rotation of the filter element, in the process of air passing through and being filtered by it, air enters the air inlet pipe, causing the elastic bag to expand. After the elastic bag expands to a certain extent, under the action of pressure, the air intake of the air inlet pipe is equal to the air outlet of the air outlet pipe, and the elastic bag no longer expands. The expanded elastic bag causes the filter element to deform, and the filter element bulges, thereby increasing the filtration area of ​​the filter element and improving the filtration effect of the filter element.

[0013] The present invention proposes an intelligent fresh air replacement device, comprising the above-mentioned fresh air replacement filter structure.

[0014] Preferably, the intelligent fresh air replacement device further comprises a body, a controller is arranged on the outer surface of the body, an air outlet is opened on the outer wall of the body, a purification component is embedded and installed inside the body, a fixing component is arranged on the inner surface of the body, and the fixing component comprises:

[0015] A fixing plate, the fixing plate is hinged on the inner surface of the body, the fixing plate is elastically connected to the inner surface of the body via a torsion spring, and an inner groove is provided inside the fixing plate;

[0017] and a clamping piece, the clamping piece passes through the outer wall of the fixing plate and is slidably connected to the fixing plate, and the clamping piece is elastically connected to the inner groove via a return spring;

[0018] Positioning plates are fixedly connected to both sides of the fixing plate, and the two groups of positioning plates are symmetrically arranged with the center line of the fixing plate as the symmetry axis. A card slot is arranged directly below the fixing component, and the card connector is card-engaged with the card slot. By pressing the card connector upward, the card connector compresses the reset spring, and the bottom of the card connector disengages from the card slot.

[0019] The present invention provides an intelligent fresh air replacement device and a fresh air replacement filter structure. It has the following beneficial effects:

[0020] (1) The fresh air replacement filter structure and the intelligent fresh air replacement device extend the telescopic end of the electric telescopic rod, so that the connecting block drives the vertical rod to move, and then the small round rod slides in the straight groove, so that the straight rod drives the disc to rotate, and the rotating shaft drives the filter element to rotate, and the angle of the filter element is adjusted to be suitable for different external air qualities. When the external air quality is good, multiple groups of filter elements are in parallel, so that air can be filtered through quickly. When the external air quality is poor, multiple groups of filter elements rotate to increase the filtering area, thereby improving the filtering effect of the filter element.

[0021] (2) The fresh air replacement filter structure and the intelligent fresh air replacement device use an auxiliary cleaning component. Through the continuous extension and retraction of the telescopic end of the electric telescopic rod, the straight rod drives the disc to reciprocate. Under the reset action of the connecting spring, the pressure plate drives the connecting rod to reciprocate, so that the piston plate reciprocates in the air chamber. When the piston plate moves toward the pressure plate, the one-way air inlet can suck the filtered air into the air chamber. When the piston plate moves away from the pressure plate, the gas in the air chamber is ejected through the one-way air outlet, thereby realizing self-cleaning of the filter element and reducing the frequency of replacement and cleaning of the fresh air replacement filter structure by users.

[0022] (3) After the filter element rotates, the air enters the air inlet pipe during the process of being filtered by the filter element. The elastic bag expands. After the elastic bag expands to a certain extent, the air inlet of the air inlet pipe is equal to the air outlet of the air outlet pipe under the action of pressure. The elastic bag no longer expands. The expanded elastic bag causes the filter element to deform and bulge, thereby further improving the filtering effect of the filter element.

[0023] (4) During the continuous extension and retraction of the telescopic end of the electric telescopic rod, the filter element of the fresh air replacement filter structure and the intelligent fresh air replacement device rotates continuously. As the angle between the air inlet pipe and the air flow changes, the elastic bag expands inconsistently under the action of pressure, causing the filter element itself to vibrate, which facilitates the shedding of impurities and improves the filtering effect of subsequent filter elements.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] See also Figure 1-Figure 3 The present invention proposes an intelligent fresh air replacement device, including a body 1, which can be hoisted at a higher place in the house. A controller 101 is arranged on the outer surface of the body 1, an air outlet 2 is opened on the outer wall of the body 1, and an air inlet is opened on the side of the body 1 away from the air outlet 2. A purification component 4 is embedded and installed inside the body 1, which can purify and disinfect the air. A fixing component 5 is arranged on the inner surface of the body 1.

[0041] In the embodiment of the present invention, the fixing assembly 5 includes a fixing plate 51, a recess 53 and a clamping member 54. The fixing plate 51 is hinged on the inner surface of the body 1. The fixing plate 51 and the inner surface of the body 1 are elastically connected by a torsion spring. An inner groove 52 is provided inside the fixing plate 51. The recess 53 is arranged on the outer wall of the fixing plate 51. The clamping member 54 penetrates the outer wall of the fixing plate 51 and is slidably connected to the fixing plate 51. The clamping member 54 and the inner groove 52 are elastically connected by a return spring. Positioning plates are fixedly connected to both sides of the fixing plate 51. The two groups of positioning plates are symmetrically arranged with the center line of the fixing plate 51 as the symmetry axis. A clamping slot is arranged directly below the fixing assembly 5, and the clamping member 54 is clamped with the clamping slot. By pressing the clamping member 54 upward, the clamping member 54 compresses the return spring, and the bottom of the clamping member 54 is separated from the clamping slot. When the bottom of the clamping member 54 is clamped with the clamping slot, the fixed plate 51 can be limited and fixed.

[0042] See also Figure 4-Figure 11 The present invention proposes a fresh air replacement filter structure, including a shell 31, the inner surface of the shell 31 is rotatably connected to a filter element 32, the interior of the shell 31 is provided with an adjustment component 33 and an auxiliary cleaning component 34, and a pull rope 35 is fixedly connected to the outer wall of the shell 31. By using the pull rope 35, the fresh air replacement filter structure can be easily pulled out of the body 1.

[0043] In the embodiment of the present invention, in order to adjust the angle of the filter element 32 and adapt to filtering the air of different qualities from the outside, specifically, the adjustment component 33 includes an electric telescopic rod 331, which is embedded in the shell 31, and the telescopic end of the electric telescopic rod 331 is fixedly connected with a connecting block 332, and the bottom of the connecting block 332 is fixedly connected with a vertical rod 333, and a small round rod 334 is fixedly connected to the outer wall of the vertical rod 333, and the filter element 32 is penetrated by the rotating shaft 321 and is fixedly connected to the rotating shaft 321, and both ends of the rotating shaft 321 are fixedly connected with a disk 337, and a straight rod 336 is fixedly connected to the outer wall of the disk 337, and a straight slot 335 is provided on the outer wall of the straight rod 336, and the small round rod 334 is slidably connected in the straight slot 335, and the small round rod 334 and the disk 337 are provided with multiple groups, and the small round rod 334 and the disk 337 are The number of groups 337 is equal. The telescopic end of the electric telescopic rod 331 is extended, the connecting block 332 drives the vertical rod 333 to move, the small round rod 334 slides in the straight slot 335, and the straight rod 336 drives the disc 337 to rotate, so that the rotating shaft 321 drives the filter element 32 to rotate, and the angle of the filter element 32 is adjusted to be suitable for different external air qualities. When the external air quality is good, multiple groups of filter elements 32 are in parallel, so that air can be filtered through quickly. When the external air quality is poor, multiple groups of filter elements 32 rotate to increase the filtering area, thereby improving the filtering effect of the filter element 32. A sensor for detecting air quality is fixedly installed in the body 1 to realize the detection of air quality. After the air quality detection is completed, the detection result signal is transmitted to the control device of the body 1, and then the start and stop of the electric telescopic rod 331 are controlled by the control device of the body 1.

[0044] Furthermore, in order to further improve the filtering effect of the filter element 32, specifically, one end of the straight rod 336 away from the disc 337 is rotatably connected to the rotating wheel 338, and a placement groove 322 is opened inside the filter element 32, and an elastic bag 323 is embedded in the placement groove 322. The elastic bag 323 is connected to the air inlet pipe 324 and the air outlet pipe 325, and the diameter of the air inlet pipe 324 is larger than the diameter of the air outlet pipe 325. After the filter element 32 rotates, during the process of air passing through it, the air enters the air inlet pipe 324, causing the elastic bag 323 to expand. After the elastic bag 323 expands to a certain extent, under the action of pressure, the air intake of the air inlet pipe 324 is equal to the air outlet of the air outlet pipe 325, and the elastic bag 323 no longer expands. The expanded elastic bag 323 causes the filter element 32 to deform, and the filter element 32 bulges, thereby further improving the filtering effect of the filter element 32.

[0045] In the embodiment of the present invention, in order to enable the filter element 32 to self-clean and reduce the frequency of the user's replacement and cleaning of the fresh air replacement filter structure, specifically, the auxiliary cleaning component 34 includes an air bin 341, the air bin 341 is fixedly connected to the inner wall of the shell 31, and a one-way air outlet 342 and a one-way air inlet 346 are opened on the outer wall of the air bin 341. The piston in the inner wall of the air bin 341 is connected to a piston plate 343, and a connecting rod 344 is fixedly connected to the outer wall of the piston plate 343. The end of the connecting rod 344 away from the piston plate 343 is fixedly connected to a pressure plate 345, and the pressure plate 345 is elastically connected to the outer wall of the air bin 341 by a connecting spring. The pressure plate 345 is reset by the connecting spring to The rotating wheels 338 are in contact with each other, and through the continuous extension and retraction of the telescopic end of the electric telescopic rod 331, the straight rod 336 drives the disc 337 to rotate back and forth. Under the reset action of the connecting spring, the pressure plate 345 drives the connecting rod 344 to reciprocate, so that the piston plate 343 reciprocates in the air chamber 341. When the piston plate 343 moves in the direction close to the pressure plate 345, the one-way air inlet 346 can suck the filtered air into the air chamber 341. When the piston plate 343 moves in the direction away from the pressure plate 345, the gas in the air chamber 341 is ejected through the one-way air outlet 342, thereby realizing the self-cleaning treatment of the filter element 32 and reducing the frequency of replacement and cleaning of the fresh air replacement filter structure by the user.

[0046] Furthermore, during the continuous extension and retraction of the telescopic end of the electric telescopic rod 331, the filter element 32 continues to rotate. Due to the change in the angle between the air inlet pipe 324 and the air flow, under the action of pressure, the elastic bag 323 expands to an inconsistent size, causing the filter element 32 itself to vibrate, which facilitates the shedding of impurities and improves the filtering effect of the subsequent filter element 32.

[0047] It should be noted that the above-mentioned electrical components are all existing technology products. Technical personnel in this field select, install and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all universal standard parts or components known to technical personnel in this field. Their structures and principles can be known to technical personnel through technical manuals or through conventional experimental methods, and no specific restrictions are made here.

[0048] When in use, outside air enters through the air inlet of the machine body 1. In the process of passing through the fresh air replacement filter structure, the air quality sensor in the machine body 1 detects the air quality. After the detection is completed, when the air quality is good, the multiple groups of filter cores 32 are in parallel, so that the air is quickly filtered through. When the outside air quality is poor, the telescopic end of the electric telescopic rod 331 is extended, the connecting block 332 drives the vertical rod 333 to move, the small round rod 334 slides in the straight groove 335, and the straight rod 336 drives the disc 337 to rotate, so that the rotating shaft 321 drives the filter core 32 to rotate, and the angle of the filter core 32 is adjusted. The multiple groups of filter cores 32 rotate to increase the filtering area;

[0049] At the same time, after the filter core 32 rotates, the air passes through the filter core 32 and enters the air inlet pipe 324, causing the elastic bag 323 to expand. After the elastic bag 323 expands to a certain extent, under the action of pressure, the air inlet of the air inlet pipe 324 is equal to the air outlet of the air outlet pipe 325, and the elastic bag 323 no longer expands. The expanded elastic bag 323 causes the filter core 32 to deform, causing the filter core 32 to bulge.

[0050] At the same time, through the continuous extension and retraction of the telescopic end of the electric telescopic rod 331, the straight rod 336 drives the disc 337 to reciprocate. Under the reset action of the connecting spring, the pressure plate 345 drives the connecting rod 344 to reciprocate, so that the piston plate 343 reciprocates in the air chamber 341. When the piston plate 343 moves in the direction close to the pressure plate 345, the one-way air inlet 346 can inhale the filtered air into the air chamber 341. When the piston plate 343 moves in the direction away from the pressure plate 345, the gas in the air chamber 341 is ejected through the one-way air outlet 342, thereby realizing the self-cleaning treatment of the filter element 32. In addition, during the continuous extension and retraction process of the telescopic end of the electric telescopic rod 331, the filter element 32 continues to rotate. Due to the change in the angle between the air inlet pipe 324 and the air flow, the elastic bag 323 expands inconsistently under the action of pressure, causing the filter element 32 itself to vibrate, which is convenient for the shedding of impurities.

[0051] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
