Description

Technical Field

[0001] This utility model relates to the field of purification and ventilation technology, specifically to an air conditioning purification and ventilation unit. Background Technology

[0002] When air conditioners ventilate, they usually use ventilation ducts. To prevent dust from outside air from entering the room through the ventilation ducts, filter plates are usually installed inside the ventilation ducts. During the process of filtering the air, dust tends to accumulate on one side of the filter plate, which in turn affects the air intake effect of the ventilation duct.

[0003] According to the search, a patent publication number CN222047997U for an air conditioning purification and ventilation device was published in China on November 22, 2024. It is roughly described as including a filter cover, an exhaust port at the front end of the filter cover, a connecting pipe installed at the rear end of the filter cover, an air filter plate slidably connected to the top end of the filter cover, and a handle fixedly connected to the top end of the air filter plate; a dust removal component is installed inside the filter cover, and an installation component is provided on the surface of the filter cover.

[0004] While the aforementioned existing technical solution facilitates the removal of dust from the surface of the air filter plate and prevents excessive dust accumulation from affecting the device's performance over a long period of use, the device tends to cause dust to fly everywhere during dust removal, making it difficult to collect and thus hindering dust cleaning. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides an air conditioning purification and ventilation unit to solve the problem mentioned in the background technology that dust is easily scattered everywhere during dust cleaning, making it difficult to collect and thus hindering dust cleaning.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: an air conditioning purification ventilation unit, including a filter cover and a collection box. The filter cover has a filter plate inside. A sliding rod is slidably connected to the top of the filter cover, and a scraper that is in close contact with the filter plate is fixedly connected to the bottom of the sliding rod. A handle is connected to the top of the sliding rod through the filter cover. A first through groove is formed on one side of the filter cover near the bottom. The collection box is placed on the inner lower side wall of the filter cover and is slidably connected to the first through groove. A first sealing plate is connected to one end of the collection box through the first through groove. A baffle plate is fixedly connected inside the filter cover, close to the top of the collection box. A through opening for the collection box is formed on the baffle plate. A threaded rod is rotatably connected inside the filter cover. A hand crank is connected to one end of the threaded rod through the filter cover. A cleaning brush that cooperates with the baffle plate is threaded onto the threaded rod. A fixing rod that is slidably connected to the cleaning brush is fixedly connected inside the filter cover.

[0009] By adopting the above technical solution, after air enters the filter cover, the filter plate is used to filter the air. After long-term use, too much dust adheres to the filter plate, reducing the filtration effect. At this time, pulling the handle drives the sliding rod and scraper to move up and down, so that the scraper cleans the dust on the filter plate, causing the dust to fly in the filter cover and then fall onto the baffle plate. Then, turning the hand crank drives the threaded rod to rotate, so that the threaded rod drives the cleaning brush to sweep the dust on the baffle plate to the passage position, and then falls into the collection box through the passage. The baffle plate is used to reduce the probability of dust flying out of the collection box again. When it is necessary to clean the dust, pull the first sealing plate to move the collection box and take it out, so as to uniformly process the dust and achieve the purpose of facilitating the collection and cleaning of dust.

[0010] Optionally, the filter plate is slidably connected inside the filter cover, and a second through groove that mates with the filter plate is provided on the outer wall of the filter cover. One end of the filter plate passes through the second through groove and is connected to a second sealing plate. The second sealing plate is connected to the filter cover by bolts.

[0011] By adopting the above technical solution, when the filter plate is used for a long time, it is prone to wear and aging. At this time, the bolts can be removed, and the second sealing plate can be pulled to move the filter plate, thereby removing the filter plate and making it easier to replace the filter plate.

[0012] Optionally, the front end of the first sealing plate is provided with a positioning groove, a rotating rod is rotatably connected to the outer wall of the filter cover, a connecting arm is fixedly connected to one end of the rotating rod, a through hole is provided on the connecting arm, a positioning rod that cooperates with the positioning groove is slidably connected inside the through hole, a connecting head is fixedly connected to one end of the positioning rod, and a tension spring is provided between the connecting head and the connecting arm.

[0013] By adopting the above technical solution, when the collection box is inside the filter cover, rotating the rotating rod drives the connecting arm and the positioning rod to rotate. When the position of the positioning rod coincides with the positioning groove, the tension spring drives the connecting head and the positioning rod to move, so that the positioning rod is inserted into the positioning groove, thereby positioning the first sealing plate and the collection box, preventing the collection box from accidentally falling off the filter cover, and achieving the purpose of improving the stability of the equipment.

[0014] Optionally, two limiting grooves are provided on the inner side wall of the filter cover, and both ends of the scraper are fixedly connected with limiting sliders that are slidably connected to the limiting grooves.

[0015] By adopting the above technical solution, the limiting groove and the limiting slider work together to limit the scraper, so as to prevent the scraper from shaking and thus reducing the cleaning effect of the scraper on the filter plate.

[0016] Optionally, a protective grille is provided at one end of the filter cover.

[0017] By adopting the above technical solution, the protective barrier is used to reduce the probability of foreign objects entering the filter cover, thereby reducing the probability of damage to the filter plate.

[0018] (III) Beneficial Effects

[0019] In summary, this utility model has at least one of the following beneficial technical effects:

[0020] In this air conditioning purification and ventilation unit, after air enters the filter cover, the filter plate filters the air. After prolonged use, excessive dust adheres to the filter plate, reducing its filtration efficiency. At this point, pulling the handle moves the sliding rod and scraper up and down, allowing the scraper to clean the dust from the filter plate. The dust is then scattered within the filter cover and falls onto the baffle plate. Turning the hand crank rotates the threaded rod, which in turn drives the cleaning brush to sweep the dust from the baffle plate to the passage opening, where it falls into the collection box. The baffle plate reduces the probability of dust re-emerging from the collection box. When dust removal is needed, pulling the first sealing plate moves the collection box, allowing it to be removed for unified dust collection and cleaning. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Reference Figures 1-4An air conditioning purification ventilation unit includes a filter cover 1 and a collection box 2. A filter plate 3 is disposed inside the filter cover 1. A sliding rod 4 is slidably connected to the top of the filter cover 1, and a scraper 5 tightly attached to the bottom of the sliding rod 4 is fixedly connected to the bottom of the sliding rod 4. A handle 6 is connected to the top of the sliding rod 4 through the filter cover 1. A first through groove is formed on one side of the filter cover 1 near the bottom. The collection box 2 is placed on the inner lower side wall of the filter cover 1 and is slidably connected to the first through groove. One end of the collection box 2 is connected to a first sealing plate 7 through the first through groove. A baffle plate 8 is fixedly connected inside the filter cover 1, close to the top of the collection box 2. A through opening for the collection box 2 is formed on the baffle plate 8. A threaded rod 9 is rotatably connected inside the filter cover 1. One end of the threaded rod 9 passes through the filter cover 1 and is connected to a hand crank 10. A cleaning brush 11 that cooperates with the baffle plate 8 is threadedly connected to the threaded rod 9. A fixed rod 12 is connected to the cleaning brush 11. After air enters the filter cover 1, the filter plate 3 is used to filter the air. After long-term use, too much dust adheres to the filter plate 3, reducing the filtration effect. At this time, pulling the handle 6 drives the sliding rod 4 and the scraper 5 to move up and down, so that the scraper 5 cleans the dust on the filter plate 3, causing the dust to fly in the filter cover 1 and then fall onto the baffle plate 8. Then, turning the hand crank 10 drives the threaded rod 9 to rotate, so that the threaded rod 9 drives the cleaning brush 11 to sweep the dust on the baffle plate 8 to the position of the passage, and then fall into the collection box 2 through the passage. The baffle plate 8 is used to reduce the probability of dust flying out of the collection box 2 again. When it is necessary to clean the dust, pull the first sealing plate 7 to move the collection box 2 and take it out, so as to uniformly process the dust and achieve the purpose of facilitating the collection and cleaning of dust.

[0030] Reference Figures 1-4 The filter plate 3 is slidably connected inside the filter cover 1. A second through groove is provided on the outer wall of the filter cover 1 to cooperate with the filter plate 3. One end of the filter plate 3 passes through the second through groove and is connected to the second sealing plate 13. The second sealing plate 13 is connected to the filter cover 1 by bolts. When the filter plate 3 is used for a long time, it is prone to wear and aging. At this time, the bolts can be removed, and the second sealing plate 13 can be pulled to move the filter plate 3, thereby removing the filter plate 3 and making it easy to replace the filter plate 3.

[0031] Reference Figure 1 and Figure 2The first sealing plate 7 has a positioning groove at its front end. A rotating rod 14 is rotatably connected to the outer wall of the filter cover 1. A connecting arm 15 is fixedly connected to one end of the rotating rod 14. A through hole is provided on the connecting arm 15. A positioning rod 16 that cooperates with the positioning groove is slidably connected inside the through hole. A connector 17 is fixedly connected to one end of the positioning rod 16. A tension spring 18 is provided between the connector 17 and the connecting arm 15. When the collection box 2 is inside the filter cover 1, rotating the rotating rod 14 drives the connecting arm 15 and the positioning rod 16 to rotate. When the position of the positioning rod 16 coincides with the positioning groove, the tension spring 18 drives the connector 17 and the positioning rod 16 to move, so that the positioning rod 16 is inserted into the positioning groove. This positions the first sealing plate 7 and the collection box 2, preventing the collection box 2 from accidentally falling off the filter cover 1 and improving the stability of the equipment.

[0032] Reference Figure 4 and Figure 5 Two limiting grooves 19 are provided on the inner side wall of the filter cover 1. Both ends of the scraper 5 are fixedly connected to limiting sliders 20 that slide in connection with the limiting grooves 19. The limiting grooves 19 and the limiting sliders 20 cooperate to limit the scraper 5 and prevent the scraper 5 from shaking, which would reduce the cleaning effect of the scraper 5 on the filter plate 3.

[0033] Reference Figure 1 One end of the filter cover 1 is provided with a protective grille 21. The protective grille 21 is used to reduce the probability of foreign objects entering the filter cover 1, thereby reducing the probability of damage to the filter plate 3.

[0034] In summary, the working principle and process of this air conditioning purification and ventilation unit are as follows: During operation, after air enters the filter cover 1, the filter plate 3 filters the air. After prolonged use, excessive dust adheres to the filter plate 3, reducing its filtration efficiency. At this point, pulling the handle 6 moves the sliding rod 4 and scraper 5 up and down, allowing the scraper 5 to clean the dust from the filter plate 3. The dust is then dispersed within the filter cover 1 and falls onto the baffle plate 8. Turning the hand crank 10 rotates the threaded rod 9, which in turn drives the cleaning brush 11 to sweep the dust from the baffle plate 8 to the outlet, where it falls into the collection box 2. The baffle plate 8 reduces the probability of dust re-emerging from the collection box 2. When dust removal is needed, pulling the first sealing plate 7 moves the collection box 2, allowing it to be removed for unified dust collection and cleaning. After prolonged use, the filter plate 3 is prone to wear and aging. Removing the bolts allows the second sealing plate 13 to be pulled, moving the filter plate 3 and facilitating its replacement. When the collection box 2 is inside the filter cover 1, rotating the rotating rod 14 rotates the connecting arm 15 and the positioning rod 16. When the positioning rod 16 aligns with the positioning groove, the tension spring 18 moves the connecting head 17 and the positioning rod 16, inserting the positioning rod 16 into the positioning groove. This positions the first sealing plate 7 and the collection box 2, preventing the collection box 2 from accidentally detaching from the filter cover 1 and improving equipment stability. The limiting groove 19, in conjunction with the limiting slider 20, limits the scraper 5, preventing it from wobbling and reducing its cleaning effect on the filter plate 3. The protective grille 21 reduces the probability of foreign objects entering the filter cover 1, thus minimizing damage to the filter plate 3.

[0035] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
