Description

Technical Field

[0001] This invention relates to the field of ventilation technology, and more particularly to a ventilation regulating device. Background Technology

[0002] Ventilation refers to the exchange of air between the outside environment and the indoor or enclosed environment, thereby improving the air quality in the indoor or enclosed environment.

[0003] For example, a ventilation regulating device and system with publication number CN117167339A, by installing a vibration unit and a collection unit in the filter mechanism, drives a push rod to rotate via a servo motor. The push rod pushes a push block to move backward, which in turn causes a slide rod to slide backward. Then, a first spring pushes the slide rod to reset it. Through repeated impacts, the filter screen can be shaken. The dust on the surface of the filter screen is collected through the collection groove to the middle of the collection box, thereby achieving the purpose of rapid dust removal and collection. Although it can collect dust on the filter screen, in actual use, the gaps in the filter screen are relatively large, and dust can pass through the filter screen and enter the room, thereby increasing the indoor dust and failing to effectively intercept dust.

[0004] Therefore, those skilled in the art have proposed a ventilation regulating device to solve the problem that filters cannot effectively intercept dust. Summary of the Invention

[0005] In view of the above-mentioned problems existing in the prior art, the main objective of the present invention is to provide a ventilation regulating device.

[0006] The technical solution of the present invention is as follows: a ventilation regulating device includes a fixed outer shell, a grid fixedly provided on one side of the fixed outer shell, an opening at the top of the fixed outer shell, the fixed outer shell being connected to a wall, an inner tube slidably connected inside the fixed outer shell, a slider provided on the outer surface of the inner tube, an air intake structure provided at one end of the inner tube, an air exhaust structure provided at the end of the inner tube away from the air intake structure, a sealing plate fixedly provided at the end of the inner tube near the air exhaust structure, a control plate provided above the sealing plate, a filter space provided inside the inner tube, and an adjustment structure provided below the sealing plate, located inside the inner tube.

[0007] The filtration space includes a bottom support plate, which is made of transparent material. A support area is formed between the bottom support plates, and water is provided in the support area. The bottom surface of the bottom support plate is recessed towards the center area. A rubber stopper is provided at the center of the bottom support plate. A guide plate is fixedly provided on the inner wall of the inner tube above the bottom support plate.

[0008] The side of the guide plate facing the bottom support plate forms a channel with the horizontal plane within the support area.

One end of the fixing plate is fixedly connected to the inner wall of the outer shell, and the other end is fixedly connected to a fixing sleeve. An elastic knob is movably connected inside the fixing sleeve. A rotating plate is fixedly connected to the bottom end of the elastic knob. The fixing plate and the rotating plate correspond one-to-one.

[0010] In a preferred embodiment, the fixed sleeve has an annular cavity inside, a limiting post is provided inside the annular cavity, an annular block is provided on the side surface of the elastic knob, an annular groove corresponding to the limiting post is opened on the annular block, and a spring is sleeved on the limiting post.

[0011] In a preferred embodiment, the suction structure includes a suction motor, which is fixedly connected to the upper surface of the inner tube. The output shaft of the suction motor passes through one side of the inner tube and is fixedly connected to a rotating rod. The end of the rotating rod away from the suction motor is fixedly connected to a driving bevel gear. One side of the driving bevel gear is meshed with a driven bevel gear. The driven bevel gear is connected to a connecting block via a transmission rod. Several fan blades are fixedly provided on the connecting block. The transmission rod is connected to the inner wall of the inner tube via a bracket.

[0012] In a preferred embodiment, the exhaust structure and the suction structure have the same composition, the difference being that the exhaust structure supplies air from the indoor unit to the inner pipe, while the suction structure supplies air from the outdoor unit to the inner pipe. Both the exhaust structure and the suction structure are electrically connected to the control board.

[0013] In a preferred embodiment, the inner surface of the fixed housing is provided with a groove corresponding to the slider.

[0014] In a preferred embodiment, both the exhaust structure and the suction structure are provided with sliding plates below the suction motor, and the sliding plates are slidably connected to the upper opening of the fixed housing.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are that, through the bottom support plate, water and guide plate, the air entering and exiting must pass through the channel formed by the water inside the guide plate and the bottom support plate, so that the air comes into contact with the water. Since dust has a certain weight and needs to pass through a channel of a certain length, the dust will be adsorbed by the water and precipitated and filtered in the water, effectively preventing dust from entering the room.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] Example

[0028] A ventilation regulating device includes a fixed outer shell 1, a grid 2 fixedly provided on one side of the fixed outer shell 1, an open top of the fixed outer shell 1, the fixed outer shell 1 being connected to a wall, an inner tube 3 slidably connected inside the fixed outer shell 1, a slider 4 provided on the outer surface of the inner tube 3, an air intake structure 5 provided at one end of the inner tube 3, an exhaust structure 6 provided at the end of the inner tube 3 away from the air intake structure 5, a sealing plate 7 fixedly provided at the end of the inner tube 3 near the exhaust structure 6, a control plate 8 provided above the sealing plate 7, a filter space 9 provided inside the inner tube 3, and an adjustment structure 10 provided below the sealing plate 7 and inside the inner tube 3. The control plate 8 is used to start or stop the air intake structure 5 and the exhaust structure 6. The air intake structure 5 is used to transfer outside air into the room, and the exhaust structure 6 is used to exhaust indoor air to the outside. When the air enters the filter space 9 inside the inner tube 3, the dust in the air is filtered.

[0029] The filtration space 9 includes a bottom support plate 91, which is made of transparent material. A support area is formed between the bottom support plates 91, and water is placed in the support area. The bottom of the bottom support plate 91 is recessed towards the center area. A rubber stopper 93 is provided at the center of the bottom support plate 91. A guide plate 92 is fixedly provided on the inner wall of the inner tube 3 above the bottom support plate 91. When air enters the bottom support plate 91, it will come into contact with the water surface, allowing dust and water to come into contact. The dust is adsorbed by the water, thus achieving filtration. The bottom support plate 91 is made of transparent material, so the internal water level change can be directly observed through one end of the inner tube 3. The rubber stopper 93 allows for the addition and discharge of water inside the bottom support plate 91.

[0030] The side of the guide plate 92 facing the bottom support plate 91 forms a channel with the horizontal surface in the support area, forming a channel of a certain length, increasing the contact time of dust in the air, so that the dust can fully contact the water surface and achieve dust filtration.

[0031] The adjustment structure 10 includes an outer shell 101, which is part of the inner tube 3. A fixing plate 102 is provided inside the outer shell 101. One end of the fixing plate 102 is fixedly connected to the inner wall of the outer shell 101, and the other end is fixedly connected to a fixing sleeve 103. An elastic knob 104 is movably connected inside the fixing sleeve 103. A rotating plate 105 is fixedly connected to the bottom end of the elastic knob 104. The fixing plate 102 and the rotating plate 105 correspond one-to-one. By rotating the rotating plate 105, the rotating plate 105 and the fixing plate 102 are made to coincide, thereby opening the ventilation opening. By separating the rotating plate 105 and the fixing plate 102, the ventilation opening is closed.

[0032] The fixed sleeve 103 has an annular cavity 107 inside, and a limiting post 108 is provided inside the annular cavity 107. The side surface of the elastic knob 104 has an annular block 106. The annular block 106 has an annular groove corresponding to the limiting post 108. A spring 109 is sleeved on the limiting post 108. The spring 109 provides an upward rebound force to the elastic knob 104, so that when the rotating plate 105 is separated from the fixed plate 102, the rotating plate 105 and the fixed plate 102 achieve sealed contact.

[0033] The suction structure 5 includes a suction motor 51, which is fixedly connected to the upper surface of the inner tube 3. The output shaft of the suction motor 51 passes through one side of the inner tube 3. The output shaft of the suction motor 51 is fixedly connected to a rotating rod. The end of the rotating rod away from the suction motor 51 is fixedly connected to a driving bevel gear 52. One side of the driving bevel gear 52 is meshed with a driven bevel gear 53. The driven bevel gear 53 is connected to a connecting block through a transmission rod. Several fan blades 54 are fixedly provided on the connecting block. The transmission rod is connected to the inner wall of the inner tube 3 through a bracket. The suction motor 51 is placed outside the inner tube 3 to prevent water from entering the suction motor 51 and causing damage.

[0034] The exhaust structure 6 and the suction structure 5 have the same composition. The difference is that the exhaust structure 6 supplies air from the indoor to the inner pipe 3, while the suction structure 5 supplies air from the outside to the inner pipe 3. Both the exhaust structure 6 and the suction structure 5 are electrically connected to the control board 8. The exhaust structure 6 faces the indoor environment, while the suction structure 5 faces the outdoor environment.

[0035] The inner surface of the fixed housing 1 is provided with a sliding groove corresponding to the slider 4, which facilitates the sliding connection between the inner tube 3 and the fixed housing 1 and makes it convenient to inspect the inside of the inner tube 3.

[0036] Both the exhaust structure 6 and the suction structure 5 are equipped with sliding plates located below the suction motor 51. The sliding plates are slidably connected to the upper opening of the fixed housing 1, and the sliding plates are used to stabilize the position of the inner tube 3.

[0037] Working principle:

[0038] As shown in the figure, during use, the fixed housing 1 with the grid 2 is fixed inside the wall facing the outdoor environment. Then, water is injected into the area of ​​the bottom support plate 91 above the rubber plug 93 through the syringe. At the same time, the water level inside is observed through one side of the exhaust structure 6, so that the water level and the bottom surface of the guide plate 92 form a channel. Then, the inner tube 3 is inserted into the fixed housing 1, so that the sealing plate 7 and the control plate 8 seal the other end of the wall. Then, the wire on the control plate 8 is connected to an external power source. When it is necessary to fill the room with air, the suction structure 5 is activated through the control plate 8 to allow outside air to enter the room. When entering, the air passes through the channel between the water level and the guide plate 92, causing dust in the air to adhere to the water surface, thus filtering the dust and effectively preventing dust from entering the room. When it is necessary to exhaust the indoor environment, the exhaust structure 6 is activated through the control plate 8 to exhaust the indoor air to the outside, thus achieving air exchange. When it is necessary to adjust the air intake and exhaust volume, the air intake and exhaust volume are adjusted by rotating the distance between the rotating plate 105 and the fixed plate 102.

[0039] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
