Description

Technical Field

[0001] The present invention relates to the technical field of purifiers, and particularly to an indoor purifier. Background Art

[0002] An air purifier mainly consists of a housing, a fan, and a dust filter element. Among them, the impurity air is sucked into the air purifier by the fan and flows through the dust filter element under the negative pressure of the fan. At this time, the impurity suspended particles in the waste gas, such as PM10, PM2.5, etc., are intercepted by the dust filter element. The control of the treatment intensity, that is, the treatment air volume, is completed through the electronic control system. After treatment, the clean air is discharged through the fan, so as to achieve the purpose of purifying the air. The existing air purifiers have a simple treatment form and a single treatment function. Most of the air purifiers on the market capture, separate, and filter the fine particles in the gas through porous media such as filters, filter elements, and filter bags.

[0003] For the existing purifiers, after the filter screen inside the purifier housing has worked for a long time, a large amount of flocculent and granular dust will adhere to the gaps of the filter screen. Generally, it needs to be disassembled for cleaning and maintenance; during the process of the staff taking it out, due to collision or vibration, the dust on the filter screen may fall into the inside of the purifier housing. These dusts located inside the housing are difficult to clean and will affect the subsequent use of the purifier. Summary of the Invention

[0004] Based on the technical problems existing in the background art, the present invention proposes an indoor purifier, including:

[0005] A housing and a filter assembly detachably installed on the housing; the gap between the filter assembly and the housing can be sealed by a seal to ensure normal use;

[0006] The filter assembly includes a mounting plate, a filter screen, a dust collection plate, and a driving member. A through hole is formed in the middle of the mounting plate, the filter screen covers the through hole and is arranged on the mounting plate, the dust collection plate is located below the filter screen and is movably arranged on the mounting plate. A collection area with adjustable size is formed between the dust collection plate and the mounting plate. The driving member is arranged on the mounting plate and is used to drive the dust collection plate to rotate. The dust collection plate has a first working state and a second working state. When the dust collection plate is in the first working state, the top end of the dust collection plate presses against the mounting plate; when the dust collection plate is in the second working state, the top end plate of the dust collection plate is far away from the mounting plate.

[0007] Preferably, the driving member includes a movable plate, two gears, and two racks. Both ends of the dust collecting plate are provided with rotating shafts. The two rotating shafts are arranged along the length direction of the mounting plate and are rotatably mounted on the mounting plate. The two gears are arranged in one-to-one correspondence with the two rotating shafts, and the gears are fixedly sleeved on the rotating shafts. The two racks are respectively located above the two gears and are vertically slidably mounted on the mounting plate. The racks are meshed and driven with the gears. The mounting plate is provided with an elastic member that drives the racks to have an upward movement tendency. The movable plate is located at the top of the mounting plate and is connected to the two racks.

[0008] Preferably, vertical chutes are provided on both sides of the mounting plate where the filter screen is located. Connecting rods are slidably mounted on the chutes. The movable plate is connected to the tops of the two connecting rods. The two racks are arranged in one-to-one correspondence with the two connecting rods, and the racks are mounted at the bottoms of the connecting rods; the elastic member is arranged in the chute and is connected to the connecting rod.

[0009] Preferably, an insertion hole is provided on the mounting plate at a position below the movable plate and above the filter screen. The setting of this insertion hole facilitates the operation of the staff.

[0010] Preferably, the side of the dust collecting plate close to the mounting plate is arc-shaped. This arc-shaped setting is to improve the dust collecting effect of the dust collecting plate.

[0011] Preferably, the length of the dust collecting plate is greater than the projection length of the filter screen on the mounting plate. This setting is to facilitate all the dust on the filter screen to fall into the formed collection area.

[0012] Preferably, there are two filter screens, two dust collecting plates, and two driving members. The two filter screens are respectively arranged on both sides of the through hole and are mounted on the mounting plate covering the through hole. The two dust collecting plates are arranged in one-to-one correspondence with the two filter screens, and the two dust collecting plates are respectively mounted on both sides of the mounting plate. The two driving members are arranged in one-to-one correspondence with the two dust collecting plates, and the two driving members are both arranged on the mounting plate and are respectively used to drive the two dust collecting plates to rotate.

[0013] Preferably, the housing has an air inlet and an air outlet, and air pipes are connected to both the air inlet and the air outlet. A protective net is covered at the port of the air pipe.

[0014] Preferably, the elastic member is a spring. Of course, it is not limited to setting a spring, and other components with elastic recovery performance can also be used.

[0015] Compared with the prior art, an indoor purifier proposed by the present invention adopts the above technical solutions and achieves the following technical effects:

[0016] 1. Through the settings of the mounting plate and the dust collection plate, etc., a collection area with adjustable size can be formed between the dust collection plate and the mounting plate. When the filter screen is working properly, the dust collection plate is stored on the mounting plate, ensuring the normal air circulation rate inside the housing. During the upward movement of the filter screen, a collection area is formed between the dust collection plate and the mounting plate, and the collection area is used to collect the dust and the like that fall on the filter screen, preventing the dust from falling inside the housing and making it inconvenient to clean.

[0017] 2. Through the settings of the driving member, etc., under the action of the driving member, the driving member can drive the dust collection plate to rotate, thereby forming a collection area between the dust collection plate and the mounting plate, and the elastic member will be compressed. When the action of the driving member on the dust collection plate is released, under the restoring force of the elastic member, the dust collection plate will return to its initial state, with simple operation and convenient use.

[0030] Referring to Figures 1-9 , the present invention provides an indoor purifier, comprising:

[0031] A housing 1 and a filter assembly 2 detachably installed on the housing 1. Specifically, the gap between the filter assembly 2 and the housing 1 can be sealed by a sealant or the like. The housing 1 has an air inlet and an air outlet, and air pipes 7 are connected to both the air inlet and the air outlet. A protective net 8 is provided to cover the ports of the air pipes 7. For this housing 1, the equipment existing in the existing purifier is arranged inside it to achieve the corresponding purification function, but the filter screen arranged in the prior art is replaced by the filter assembly 2.

[0032] The filter assembly 2 includes a mounting plate 21, a filter screen 22, a dust collection plate 23, and a driving member 24. A through hole is formed in the middle of the mounting plate 21, and the filter screen 22 covers the through hole and is arranged on the mounting plate 21. The filter screen 22 is used to filter impurities in the air, etc.; the dust collection plate 23 is located below the filter screen 22 and is movably arranged on the mounting plate 21. A collection area with adjustable size is formed between the dust collection plate 23 and the mounting plate 21. The driving member 24 is arranged on the mounting plate 21, and the driving member 24 is used to drive the dust collection plate 23 to rotate. The specific working process: when the filter assembly 2 is in the Figure 1 state, the filter assembly 2 is arranged on the housing. At this time, the dust collection plate 23 has a first working state and a second working state. When the dust collection plate 23 is in the first working state, the top end of the dust collection plate 23 abuts against the mounting plate 21, that is, no collection area is formed between the dust collection plate 23 and the mounting plate 21. Referring to Figure 2 , Figure 4 ,Figure 8 As shown, the dust collecting plate 23 is received and pressed against the mounting plate 21, which does not affect the air flow rate inside the housing 1. At this time, the filtering component 2 can work normally; when the filtering component 2 needs to be moved upward for disassembly and replacement, the driving member 24 is used to drive the top end of the dust collecting plate 23 to rotate away from the mounting plate 21, and a collection area as described above will be formed between the dust collecting plate 23 and the mounting plate 21. Refer to Figure 3 , Figure 6 , Figure 9 As shown, that is, when the dust collecting plate 23 is in the second working state, during the upward movement of the mounting plate 21, if the mounting plate 21 shakes and causes the dust on the filter screen 22 to fall off, the dust will fall on the dust collecting plate 23. Furthermore, the upward movement of the mounting plate 21 will drive the dust on the dust collecting plate 23 to move upward, preventing the dust from falling inside the housing 1, which is convenient to use. Preferably, in order to improve the dust collection effect, the side of the dust collecting plate 23 close to the mounting plate 21 is set to be arc-shaped; at the same time, in order to ensure that all the dust will fall on the dust collecting plate 23, the length of the dust collecting plate 23 is set to be greater than the projection length of the filter screen 22 on the mounting plate 21.

[0033] Refer to Figures 2-7 , the driving member 24 includes a movable plate 241, two gears 242, and two racks 243. Rotating shafts 3 are provided at both ends of the dust collecting plate 23. The two rotating shafts 3 are arranged along the length direction of the mounting plate 21 and are rotatably mounted on the mounting plate 21. The two gears 242 are arranged in one-to-one correspondence with the two rotating shafts 3, and the gears 242 are fixedly sleeved on the rotating shafts 3. The two racks 243 are respectively located above the two gears 242 and are vertically slidably mounted on the mounting plate 21. The racks 243 are in meshing transmission with the gears 242. An elastic member 4 for driving the rack 243 to have an upward movement tendency is provided on the mounting plate 21. Preferably, the elastic member 4 is a spring. The movable plate 241 is located at the top end of the mounting plate 21 and is connected to the two racks 243.

[0034] Furthermore, vertical chutes are provided on both sides of the mounting plate 21 where the filter screen 22 is located. Connecting rods 5 are slidably mounted on the chutes. The movable plate 241 is connected to the top ends of the two connecting rods 5. The two racks 243 are arranged in one-to-one correspondence with the two connecting rods 5, and the racks 243 are mounted at the bottom ends of the connecting rods 5; the elastic member 4 is arranged in the chute and is connected to the connecting rod 5. Working principle: When the filtering component 2 is inside the housing 1 and needs to be disassembled, the movable plate 241 can be moved downward until the movable plate 241 presses against the top end of the mounting plate 21. The downward movement of the movable plate 241 will drive the connecting rod 5 to move downward, and the elastic member 4 will be compressed. Furthermore, the connecting rod 5 will drive the rack 243 to move downward. The downward movement of the rack 243 will drive the gear 242 to rotate, and then the rotating shaft 3 will drive the dust collecting plate 23 to rotate. The dust collecting plate 23 will change from the Figure 2 state to the Figure 3The state changes, that is, a collection area as described above is formed between the dust collection plate 23 and the mounting plate 21. Then, the mounting plate 21 can be moved upward, and the dust and the like that fall during the upward movement of the filter screen 22 along with the mounting plate 21 will fall on the collection area, facilitating centralized processing by the staff. When the downward driving effect on the movable plate 241 is released, under the restoring force of the elastic member 4, the elastic member 4 will drive the connecting rod 5 to move upward, and then the movable plate 241 will move upward to return to the initial position.

[0035] Furthermore, referring to Figures 2-3 , in order to facilitate the formation of the collection area and the upward movement of the mounting plate 21 by the staff, an insertion hole 6 is provided on the mounting plate 21 at a position below the movable plate 241 and above the filter screen 22. During use, the thumb of the staff can press the movable plate 241 downward to make the movable plate 241 press against the top of the mounting plate 21 to form the collection area, and the other four thumbs can pass through the insertion hole 6 and move upward, thereby moving the mounting plate 21 upward.

[0036] In order to better collect the dust and the like that fall during the movement of the filter screen, there are two filter screens 22, two dust collection plates 23, and two driving members 24. The two filter screens 22 are respectively arranged on both sides of the through hole and are mounted on the mounting plate 21 covering the through hole. The two dust collection plates 23 are arranged in one-to-one correspondence with the two filter screens 22, and the two dust collection plates 23 are respectively mounted on both sides of the mounting plate 21. The two driving members 24 are arranged in one-to-one correspondence with the two dust collection plates 23, and the two driving members 24 are both arranged on the mounting plate 21 and are respectively used to drive the two dust collection plates 23 to rotate.

[0037] Referring to Figure 1 , in order to better move the filter assembly out of the housing, a rectangular hole through which the filter assembly can pass can be provided on the housing. The width of the rectangular hole can be set to allow the collection area formed by the two dust collection plates to pass through. And when the filter assembly is mounted on the housing, a sealing member is provided to block the gap of the rectangular hole. Or, when the mounting plate is about to move out of the housing, the action on the movable plate can be released. At this time, the dust collection plate refers to Figure 2 state, and the dust will be contained therein, and the housing can allow the mounting plate in this state to move out.

[0038] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
