Description

Technical Field

[0001] This utility model relates to the field of air purification technology, specifically to an air intake device and an air purifier. Background Technology

[0002] With the increasing popularity of pet ownership, pet hair, dander, and odors from pet activities have gradually become significant issues affecting the home environment. Most pet air purifiers on the market only function as ordinary air purifiers; while they can filter particulate matter and odors, they are less efficient at removing pet hair, thus impacting their air purification effect. Utility Model Content

[0003] In view of this, the present invention provides an air intake device and an air purifier to solve the problem that the purifiers in the related art have low efficiency in cleaning pet hair.

[0004] Firstly, this utility model provides an air intake device, comprising:

[0005] The main body has air inlets at least on its perimeter;

[0006] A grille structure is installed at the air inlet at an adjustable angle.

[0007] Beneficial effects: Because the angle of the grille structure set at the air inlet is adjustable, the air intake angle range is expanded. This allows the air purifier to effectively increase the purification range after the air intake device is set up. It can absorb and clean dust and fine floating particles in the air over a larger area, improve the air purifier's cleaning efficiency for pet hair and the air purification effect, and effectively improve indoor air quality.

[0008] In one alternative embodiment, the rotation axis of the grid structure is parallel to the axis of the main body.

[0009] Beneficial effects: The rotation axis of the grille structure is parallel to the axis of the main body, meaning that the rotation axis of the grille structure is set vertically in the working state. The grille structure rotates along the vertical rotation axis. Compared with a fixed grille, especially at the boundary of the air inlet, it can absorb air exceeding the boundary range into the air intake device, which improves the purifier's absorption efficiency of fine floating particles such as pet hair in the air, improves the air purification effect, and also enhances user satisfaction.

[0010] In one alternative embodiment, the grille structure includes:

[0011] The grille has an air inlet channel formed between each pair of adjacent grilles; the grille has a first position perpendicular to the plane of the air inlet and a second position that closes the air inlet; the grille rotates and switches between the first position and the second position to change the air inlet angle and air inlet area of ​​the air inlet channel.

[0012] Beneficial effects: The grille can rotate between a first position perpendicular to the plane of the air inlet and a second position with the air inlet closed, which allows for convenient adjustment of the air inlet angle and air inlet area, increasing the air inlet range of the air inlet device so that the air inlet device can absorb pollutants in the air over a larger area and improve the purification efficiency of the air purifier.

[0013] In one optional embodiment, the air intake device further includes:

[0014] A driving component is used to drive the grille plate to rotate;

[0015] The transmission assembly includes a meshing gear and a rack, the gear being connected to the drive member and the rack being drivenly connected to the rotating shaft of the grating plate.

[0016] Beneficial effects: Using a drive unit to rotate the grating plate saves time and effort, and facilitates automatic control. The use of a gear and rack assembly for transmission ensures high transmission stability, allowing the grating plate to reliably rotate into position and preventing jamming that could affect cleaning efficiency.

[0017] In one optional embodiment, the air intake device further includes:

[0018] Pet recognition sensors are used to identify the location of pets;

[0019] The controller is connected to both the pet recognition sensor and the drive unit.

[0020] Beneficial effects: With the pet recognition sensor installed in the air intake device, the location of the pet can be easily and quickly identified and fed back to the controller. The controller can then control the drive components to adjust the air intake corresponding to the location of the pet so that it faces the pet directly, while closing the air intakes that do not correspond to the location of the pet. This increases the suction power at the air intake corresponding to the location of the pet, significantly improving the air volume and speed, and effectively enhancing the purification efficiency of the air purifier.

[0021] In one optional embodiment, the main body is a quadrangular prism, and the four air inlets are respectively disposed on the four sides of the main body; each air inlet is provided with a grille structure.

[0022] Secondly, this utility model also provides an air purifier, comprising:

[0023] The air intake device described in any of the above items;

[0024] Air vent;

[0025] A filter device is installed in the airflow channel between the air inlet and the air outlet.

[0026] Beneficial effects: Since the air purifier includes the air intake device of this utility model, the air intake device can expand the air intake angle range, so that the air purifier with the air intake device can effectively increase the purification range, absorb and clean dust and fine floating objects in the air over a larger range, improve the air purifier's cleaning efficiency for pet hair and the air purification effect, and effectively improve indoor air quality.

[0027] In one optional implementation, the air purifier further includes:

[0028] A pet attractor is used to lure pets to the air purifier.

[0029] Beneficial effects: Using a pet attractor draws pets to the air purifier, keeping the pet's activity area close to the air purifier, thereby improving the purification effect.

[0030] In one alternative implementation, the pet attracting device comprises any one or any combination of the following:

[0031] Scent attractor device, used to emit scents that pets are sensitive to;

[0032] A light projection device used to project light spots onto the ground;

[0033] A sound attractor device used to play pet barks or sounds that pets are sensitive to.

[0034] Beneficial effects: By emitting pet-sensitive scents through scent attraction devices, projecting light spots onto the ground through light projection devices to attract pets, and playing pet barks or pet-sensitive sounds through sound attraction devices, pets can be attracted using any of the above methods or any combination of the three methods. This makes the pet's activity trajectory more concentrated near the air purifier, greatly improving the adsorption effect on pet hair and enhancing the quality of the indoor environment.

[0035] In one alternative implementation, the pet attractor includes:

[0036] The box contains a speaker, a laser emitter, and a fan blade.

[0037] Beneficial effects: The speaker, laser emitter, and fan blades are all housed inside the box, making it easy to install the pet attractant into a suitable position on the air purifier through the box, and facilitating disassembly and maintenance.

[0038] In one alternative embodiment, the odor-attracting device is positioned near the air outlet.

[0039] Beneficial effects: The odor-attracting device is located near the air outlet, and the airflow can help diffuse the scent that attracts pets into the surrounding air, thereby appropriately reducing the power of the fan blades. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0071] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0072] Most pet air purifiers on the market are simply renamed versions of ordinary air purifiers. They only have the functions of ordinary air purifiers and lack any additional features tailored to pet owners and their pets, resulting in limited air purification effects. Therefore, this utility model is proposed.

[0073] The following is combined Figures 1 to 7 The following describes embodiments of the present invention.

[0074] According to embodiments of the present invention, on the one hand, such as Figure 1 As shown, an air intake device is provided, comprising:

[0075] The main body 10 has air inlets 4 on at least its perimeter;

[0076] The grille structure 1 is set at the air inlet 4 at an adjustable angle.

[0077] Because the angle of the grille structure 1 set at the air inlet 4 is adjustable, the air intake angle range is expanded, which allows the air purifier to effectively increase the purification range after the air intake device is set, and can absorb and clean dust and fine floating objects in the air over a larger range. This improves the air purifier's cleaning efficiency for pet hair and the air purification effect, effectively improving indoor air quality. Figure 6 The diagram shows the cleaning range after the angle of the grille structure 1 is adjustable. The dashed line in the diagram shows the boundary of the air inlet 4, and the arrow in the diagram indicates the air intake direction.

[0078] In some embodiments, the air inlets 4 are only located around the periphery of the main body 10. In other embodiments, some air inlets 4 may also be located on the top surface of the main body 10. This arrangement of the air inlets 4 around the periphery of the main body 10 allows for consideration of multiple directions. The main body 10 can be any type of rotating body, such as a cylinder or a polygonal prism. When the main body 10 is cylindrical, the air inlets 4 can be arranged in a circle, with at least two grille structures 1 connected end-to-end at the air inlets 4. Alternatively, multiple air inlets 4 can be distributed circumferentially at intervals, with each air inlet 4 having one grille structure 1. When the main body 10 is a polygonal prism, generally at least one air inlet 4 is provided on each side. Preferably, each grille structure 1 has its rotation angle individually controlled to open specific air inlets 4 as needed, increasing suction power and adapting to diverse customer requirements.

[0079] In some embodiments, the rotation axis L1 of the grid structure 1 is parallel to the axis of the main body 10.

[0080] The rotation axis of the grille structure 1 is parallel to the axis of the main body 10. That is, the rotation axis of the grille structure 1 is set vertically in the working state. The grille structure 1 rotates along the vertical rotation axis. Compared with a fixed grille, especially at the boundary of the air inlet 4, it can absorb air exceeding the boundary range into the air intake device, which improves the purifier's absorption efficiency of fine floating objects such as pet hair in the air, improves the air purification effect, and also enhances user satisfaction.

[0081] In other embodiments, the rotation axis of some grille structures 1 can also be set at a certain angle to the axis of the main body 10, such as being set in the horizontal direction. This can expand the suction and cleaning range in the vertical direction. In some compact layout scenarios where the height is insufficient, the vertical height of the air inlet 4 can be appropriately reduced.

[0082] In some embodiments, such as Figure 2 As shown, the grid structure 1 includes:

[0083] The grille 11 has an air inlet channel 41 formed between each two adjacent grille plates 11; the grille 11 has a first position perpendicular to the plane of the air inlet 4 and a second position that closes the air inlet 4; the grille 11 rotates and switches between the first position and the second position to change the air inlet angle and air inlet area of ​​the air inlet channel 41.

[0084] The grille 11 rotates between a first position perpendicular to the plane of the air inlet 4 and a second position where the air inlet 4 is closed, which conveniently adjusts the air inlet angle and air inlet area of ​​the air inlet channel 41, increases the air inlet range of the air inlet device, so that the air inlet device can absorb pollutants in the air over a larger range and improve the purification efficiency of the air purifier.

[0085] Specifically, such as Figure 2 As shown, a connector 12 is provided at the top of the grille plate 11. The connector 12 is connected to the rack 22 of the transmission assembly 2, thereby driving the grille plate 11 to rotate. The operation of the grille structure 1 is as follows: when the camera detects that the pet 100 is on one side, it sends a signal to the controller. The controller controls the motor. The motor rotates, which drives the gear 21 to rotate. The gear 21 pushes the rack 22 to move in a straight line. A U-shaped groove is provided on the side of the rack 22 away from the meshing teeth. When the rack 22 moves in a straight line, the U-shaped groove clamps the connector 12 of the louver head and swings left and right, thereby realizing the opening and closing of the air inlet 4 and the control of the air inlet angle.

[0086] Figure 4The angle α is the angle between the grille plate 11 and the surface where the air inlet 4 is located.

[0087] In some embodiments, the air intake device further includes:

[0088] Drive component 3 is used to drive the grille plate 11 to rotate;

[0089] The transmission assembly 2 includes a meshing gear 21 and a rack 22. The gear 21 is connected to the drive component 3, and the rack 22 is connected to the rotating shaft of the grid plate 11.

[0090] Using drive component 3 to drive the grating plate 11 to rotate saves time and effort and facilitates automatic control. The transmission is achieved using gear 21 and rack 22 assembly, which provides high transmission stability and ensures that the grating plate 11 can reliably rotate into place, preventing the grating plate 11 from jamming and affecting the cleaning effect.

[0091] Specifically, the driving component 3 is a drive motor, and the rotation direction of the grid plate 11 can be controlled by controlling the forward and reverse rotation of the drive motor.

[0092] In some embodiments, the air intake device further includes:

[0093] Pet recognition sensor 7 is used to identify the location of pet 100;

[0094] The controller is connected to the pet recognition sensor 7 and the drive unit 3, respectively.

[0095] After the air intake device is equipped with a pet recognition sensor 7, it can easily and quickly identify the location of the pet 100 and provide feedback to the controller. The controller can then control the drive unit 3 to adjust the air intake 4 corresponding to the location of the pet 100 so that it faces the pet 100 directly. At the same time, it closes the air intake 4 that does not correspond to the location of the pet 100, thereby increasing the suction at the air intake 4 corresponding to the location of the pet 100. This significantly increases the air intake volume and speed, effectively improving the purification efficiency of the air purifier.

[0096] In some embodiments, the main body 10 is a quadrangular prism, and the four air inlets 4 are respectively disposed on the four sides of the main body 10; each air inlet 4 is provided with a grille structure 1.

[0097] According to an embodiment of the present invention, another aspect provides an air purifier, comprising:

[0098] Air intake device;

[0099] Air outlet 5 is located above air inlet 4;

[0100] A filter device is installed in the airflow channel between the air inlet 4 and the air outlet 5.

[0101] Because the air purifier includes the air intake device of this utility model, the air intake device can expand the air intake angle range, so that the air purifier with the air intake device can effectively increase the purification range, absorb and clean dust and fine floating objects in the air over a larger range, improve the air purifier's cleaning efficiency for pet hair and the air purification effect, and effectively improve indoor air quality.

[0102] In some embodiments, the air purifier further includes:

[0103] Pet attraction device 6 is used to attract pet 100 to the air purifier.

[0104] The pet attractor 6 is used to lure the pet 100 to the air purifier. The pet 100's activity area is close to the air purifier, thereby improving the purification effect.

[0105] In some embodiments, the pet attracting device 6 includes any one or any combination of the following:

[0106] Scent attractor 63, used to emit scents that are 100% sensitive to pets;

[0107] Light projection device 62 is used to project light spots onto the ground;

[0108] The sound attracting device 61 is used to play the barking of pet 100 or the sensitive sounds of pet 100.

[0109] The air purifier attracts the pet 100 by emitting a scent that the odor attractor 63 can emit, by projecting light spots onto the ground using a light projection device 62, and by playing the pet 100's barking or other sounds that the pet 100 is sensitive to using a sound attractor 61. By using any one of these methods or any combination of the three methods, the pet 100's activity trajectory is more concentrated near the air purifier, which greatly improves the adsorption effect on the pet 100's loose fur and improves the quality of the indoor environment.

[0110] In some embodiments, the pet attraction device 6 includes:

[0111] The box contains a speaker, a laser emitter, and a fan blade 64.

[0112] The speaker, laser emitter, and fan blade 64 are all housed inside the box, making it easy to install the pet attractant 6 into a suitable position on the air purifier through the box, and facilitating disassembly and maintenance.

[0113] In some embodiments, the odor-attracting device 63 is positioned near the air outlet 5.

[0114] The odor-attracting device 63 is located near the air outlet 5. The air outlet can help diffuse the odor attracted by the pet 100 into the surrounding air, thereby appropriately reducing the power of the fan blade 64.

[0115] This utility model provides a dedicated air purifier for pets (100). The air inlet 4 is designed as a louvered, swinging inlet 4, including multiple grille plates 11. The adjustable angle of the grille plates 11 allows for a wider adsorption angle range, purifying air over a larger area. This wider coverage effectively removes pet hair from the air. Furthermore, a pet attraction device 6 is added, using sound, light, and scent to attract the pet (100) closer, thereby improving the air purification efficiency in the pet's activity area.

[0116] like Figure 3 As shown, the air purifier has four cameras near the top, one in each direction, to detect the pet's location within a 100-degree radius. Simultaneously, the air purifier has louvered air inlets 4 (air inlets 4 with grille structures 1) in all four directions. When the machine is not turned on, all louvers (grille structures 1) are closed; when the air purifier is turned on, the louvers open to enter operating mode. There are air inlets 4 in all four directions, as... Figure 6 As shown, the suction force is basically the same in all directions. This air purifier uses a camera to identify the pet's location (e.g., 100°). Figure 7 As shown, only the louvered air inlet 4 located where the pet 100 is located is opened, while the other air inlets 4 are closed. This maintains a higher air pressure in the currently open direction, ensuring strong suction without requiring a high fan speed, effectively picking up loose hair and saving energy. The louvered structure's slats (grille 11) can rotate 0-90° left and right, further adjusting the air inlet to face the pet 100 to maximize the removal of loose hair and debris.

[0117] It should be noted that pet hair and dander generally fall to the ground or float near the ground, so placing the air inlet at the bottom of the main unit allows for more effective purification and absorption of pet hair and dander. Placing the air outlet above the air inlet, in the middle or upper part of the main unit, facilitates the diffusion of the purified air.

[0118] The pet 100's hair-attracting effect is limited when it's far from the air purifier; therefore, a pet attraction device 6 is installed near the top front of the machine. This ensures greater appeal to various pets, including cats and dogs, compared to simply using a plush ball or a bottom ball to attract the pet 100 to play. Figure 5As shown, the pet attraction device 6 consists of three parts: light attraction, sound attraction, and scent attraction. Light attraction projects a light spot onto the ground; the color can be selected by the user and changed according to the pet's preferences. Attracting the pet to chase the light spot will draw it nearby. Sound attraction uses a speaker to play cat or dog barks or user-defined sounds, which can be adjusted based on the pet's sensitivity to sound. Scent attraction uses a built-in fan and space where the user can place small items with scents that interest the pet; the fan will then blow out the scents, attracting the pet. The user can choose to activate one or more of the sound and scent attraction methods at any time, tailoring the approach to different pets. After attracting the pet to the air purifier, the rotating blinds maximize the removal of pet hair and debris.

[0119] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
