Description

Technical Field

[0001] The present invention relates to the field of air purification equipment, in particular to a pet air purifier. Background Art

[0002] Pets shed hair easily. This hair not only spreads throughout the room but also becomes suspended in the air. If not cleaned up promptly, the accumulated hair can create odors, breed bacteria and mites, and spread throughout the indoor air.

[0003] Although most of the floor-standing air purifiers for pets on the market currently only have the function of absorbing hair, since the main usage scenario of floor-standing air purifiers is to discharge the purified air upward (mainly to emit the filtered air to the breathing height of the human body), this is of little help in absorbing pet hair on the ground. Therefore, for families with pets, the current air purifiers are not very effective.

[0004] Therefore, the present invention provides a pet air purifier. Summary of the Invention

[0005] In response to the problems in the prior art, the purpose of the present invention is to provide a pet air purifier that overcomes the difficulties of the prior art, can more effectively expand the range of movement of the air flow, and enhance the effect of inhaling pet hair on the ground, optimize the air purification capacity, and improve the user experience of pet owners.

[0006] An embodiment of the present invention provides a pet air purifier, comprising:

[0007] A purifier base, wherein an air filter is provided inside the purifier base;

[0008] A purifier body connected to the upper portion of the purifier base, wherein the purifier base is provided with a fan for generating an air flow based on filtered air and an air outlet opening upward;

[0009] A diffusion table top, the bottom surface of which is connected to an inverted frustum, the frustum is inserted into the air outlet, the outer periphery of the frustum forms an inwardly concave cone, the radius w of the lower bottom surface of the frustum is greater than the radius s of the air outlet, the inwardly concave cone cooperates with the air outlet to form a first working state that guides the vertical air flow of the air outlet to bend in a horizontal direction to promote the backflow of the air filter.

[0010] Preferably, in the first working state, the vertical air flow emitted from the air outlet bends along the concave cone surface, first moves in the horizontal direction, and then descends, driving the surface air flow to be sucked into the air filter to form a vortex airflow based on the vertical surface.

[0011] Preferably, the vortex airflow carries pet hair on the ground into the purifier base and is filtered by the air filter.

[0012] Preferably, when the diffusion tabletop drives the circular table to rise, the concave cone cooperates with the air outlet to form a second working state in which the vertical air flow from the air outlet is guided to diffuse around along the concave cone surface and then continue to rise.

[0013] Preferably, the radius R of the diffusion table top is ≥ the radius w of the lower bottom surface of the cone, the distance between the bottom surface of the diffusion table top and the air outlet is H, in the first working state, H ≤ (ws), in the second working state, H> (ws).

[0014] Preferably, the radius w of the lower bottom surface of the cone is greater than 1.3 times the radius s of the air outlet.

[0015] Preferably, the air outlet of the purifier body is further provided with a sliding component for vertically lifting the circular table.

[0016] Preferably, the fan includes a motor, an impeller driven by the motor, an inner wall of an air outlet ring formed by the outer casing of the motor, and an outer wall of an air outlet ring formed by the inner wall of the purifier body. The upper bottom surface of the cone is connected to the top of the fan, and the concave conical surface is connected to the streamline of the inner wall of the air outlet ring.

[0017] Preferably, the fan further comprises an air inlet, which is arranged inside the air filter. In the vortex airflow, the air inlet provides suction force to draw surface air around the purifier body into the air filter.

[0018] Preferably, the purifier base further includes an outer cage, which surrounds the outer circumference of the air filter.

[0019] The pet air purifier of the present invention can more effectively expand the range of movement of the air flow, and enhance the effect of sucking in pet hair on the ground, optimize the air purification capacity, and improve the user experience of pet owners.

[0055] Figure 1 It is a three-dimensional diagram of the pet air purifier of the present invention. Figure 2 It is a side view of the pet air purifier of the present invention. Figure 3 It is a cross-sectional view of the pet air purifier of the present invention. Figure 4 This is a schematic diagram of the pet air purifier of the present invention being switched to a first working state. Figure 5 FIG1 is a top view of the pet air purifier of the present invention switched to the first working state. Figures 1 to 5As shown, the pet air purifier of the present invention comprises: a purifier base 5, a purifier body 2 and a diffusion table top 1 connected in sequence from bottom to top. Among them, an air filter 4 is provided inside the purifier base 5. The purifier body 2 is connected to the upper part of the purifier base 5, and the purifier base 5 is provided with a fan 6 that generates an air flow based on the filtered air and an upwardly opening air outlet 3. The bottom surface of the diffusion table top 1 is connected to an inverted frustum 11, which is inserted into the air outlet 3. The outer periphery of the frustum forms an inward conical surface 14. The radius w of the lower bottom surface of the frustum is greater than the radius s of the air outlet 3. The inward conical surface 14 cooperates with the air outlet 3 to form a first working state that guides the vertical air flow of the air outlet 3 to bend horizontally to promote the return flow of the air filter 4. Compared with traditional pet air purifiers, the pet air purifier of the present invention greatly enhances the ability of the air flow to diffuse horizontally at low heights (within the range of 40cm-60cm from the ground), thereby enhancing the ability to disturb the ground air around the pet air purifier.

[0056] Especially in the first operating state (which focuses more on absorbing pet hair on the ground), the distance between the concave conical surface 14 and the air outlet 3 is relatively narrow. The vertical air flow emitted from the air outlet 3 bends along the concave conical surface 14, first moves horizontally, and then descends, driving the surface air flow into the air filter 4, forming a vertical vortex airflow 9. Compared with traditional pet air purifiers, the vortex airflow 9 generated by the pet air purifier of the present invention can carry more pet hair 8 on the ground into the purifier base 5 and be filtered by the air filter 4, thereby greatly enhancing the ability to automatically absorb pet hair.

[0057] Figure 6 Schematic diagram of the pet air purifier of the present invention switching to the second working state. Figure 6 As shown, the pet air purifier of the present invention also includes a second working state (the second working state focuses more on directly emitting filtered air to the breathing height of the human body, similar to a traditional floor-standing air purifier). When the diffusion table top 1 drives the circular table to rise, the distance between the concave cone 14 and the air outlet 3 becomes larger, and the lateral guiding ability of the concave cone 14 for the air flow decreases, resulting in the concave cone 14 cooperating with the air outlet 3 to form a second working state in which the vertical air flow of the air outlet 3 is guided to diffuse along the concave cone 14 to the surroundings and then continues to rise, which is similar to the traditional air purifier mode.

[0058] In a preferred embodiment, the radius R of the diffusion table top 1 is ≥ the radius w of the lower bottom surface of the cone, and the distance between the bottom surface of the diffusion table top 1 and the air outlet 3 is H. In the first working state, H ≤ ws, and in the second working state, H > ws. As the distance H between the bottom surface of the diffusion table top 1 and the air outlet 3 increases, the lateral guiding ability of the concave conical surface 14 for the air flow decreases; as the distance H between the bottom surface of the diffusion table top 1 and the air outlet 3 decreases, the lateral guiding ability of the concave conical surface 14 for the air flow increases, but the present invention is not limited to this.

[0059] In a preferred embodiment, the radius w of the lower bottom surface of the cone is greater than 1.3 times the radius s of the air outlet 3 , but is not limited thereto.

[0060] In a preferred embodiment, the radius w of the lower bottom surface of the cone is greater than 1.4 times the radius s of the air outlet 3 , but is not limited thereto.

[0061] In a preferred embodiment, the radius w of the lower bottom surface of the cone is greater than 1.5 times the radius s of the air outlet 3 , but is not limited thereto.

[0062] In a preferred embodiment, the radius w of the lower bottom surface of the cone is greater than 1.6 times the radius s of the air outlet 3 , but is not limited thereto.

[0063] In a preferred embodiment, the air outlet 3 of the purifier body 2 is further provided with a sliding assembly (not shown in the figure) for vertically lifting the round table, but the present invention is not limited thereto.

[0064] In a preferred embodiment, the fan 6 includes a motor, an impeller 63 driven by the motor, an air outlet ring inner wall 61 formed by the motor casing, and an air outlet ring outer wall 62 formed by the inner wall of the purifier body 2. The upper bottom surface of the cone is connected to the top of the fan 6, and the concave conical surface 14 is streamlined with the air outlet ring inner wall 61, thereby forming a guiding structure for changing the direction of the air flow, but not limited to this.

[0065] In a preferred embodiment, the fan 6 further includes an air inlet 64, which is disposed inside the air filter 4. In the vortex airflow 9, the air inlet 64 provides suction to draw the surface air around the purifier body 2 into the air filter 4, but is not limited thereto.

[0066] In a preferred embodiment, the purifier base 5 further includes an outer cage 7 , which surrounds the outer circumference of the air filter 4 , thereby protecting the air filter 4 and preventing pets from scratching the air filter 4 , but the present invention is not limited thereto.

[0067] Specific embodiments of the present invention include:

[0068] refer to Figures 1 to 6As shown, the pet air purifier of the present invention includes: a purifier base 5, a purifier body 2 and a diffusion table top 1 connected in sequence from bottom to top. Among them, an air filter 4 and an outer cage 7 are provided inside the purifier base 5. The purifier body 2 is connected to the upper part of the purifier base 5, and the purifier base 5 is provided with a fan 6 for generating air flow based on filtered air and an upwardly opening air outlet 3. The bottom surface of the diffusion table top 1 is connected to an inverted frustum 11, which is inserted into the air outlet 3. The outer periphery of the frustum forms an inward conical surface 14, and the radius w of the lower bottom surface of the frustum is greater than the radius s of the air outlet 3. The pet air purifier of the present invention has a first working state that focuses on adsorbing hair and a second working state of traditional air purification. The inward concave conical surface 14 cooperates with the air outlet 3 to form a first working state that guides the vertical air flow of the air outlet 3 to bend in the horizontal direction to promote the backflow of the air filter 4. Compared to conventional pet air purifiers, the pet air purifier of the present invention significantly enhances the ability to horizontally diffuse airflow at low altitudes (between 40cm and 60cm above the ground), thereby enhancing its ability to disturb the ground air surrounding the pet air purifier. The fan 6 includes an air inlet 64, a motor, an impeller 63 driven by the motor, an air outlet ring inner wall 61 formed by the motor housing, and an air outlet ring outer wall 62 formed by the inner wall of the purifier body 2. The upper bottom surface of the truncated cone 14 is connected to the top of the fan 6. The lower vertical guide side 12 of the concave conical surface 14 is connected to the inner wall 61 of the air outlet ring in a streamlined manner. The upper horizontal diffusion side 13 is connected to the bottom surface of the diffusion table 1 in a streamlined manner. The concave conical surface 14 and the air outlet 3 cooperate to form a guiding structure that changes the direction of the airflow. The air inlet 64 is located within the air filter 4. In the vortex airflow 9, the air inlet 64 provides suction to draw the surface air around the purifier body 2 into the air filter 4. The outer cage 7 surrounds the outer periphery of the air filter 4 to protect the air filter 4 and prevent the air filter 4 from being scratched by pets.

[0069] See also Figure 4 、 5As shown, in the first operating state, the distance H1 between the concave conical surface 14 and the air outlet 3 is relatively narrow. The vertical airflow emitted from the air outlet 3 bends along the concave conical surface 14, first moving horizontally, then descending and drawing the surface airflow into the air filter 4, forming a vertical-plane-based vortex airflow 9. The radius R of the diffusion table 1 is ≥ the radius w of the lower bottom surface of the cone. The distance between the bottom surface of the diffusion table 1 and the air outlet 3 is H. In the first operating state, H ≤ ws. As the distance H between the bottom surface of the diffusion table 1 and the air outlet 3 decreases, the concave conical surface 14's ability to laterally guide the airflow increases. The first operating state focuses more on absorbing pet hair on the ground. Compared with traditional pet air purifiers, the vortex airflow 9 generated by the pet air purifier of the present invention can carry more pet hair 8 on the ground into the purifier base 5 and be filtered by the air filter 4, thereby greatly enhancing the ability to automatically absorb pet hair.

[0070] See also Figure 6 As shown, the pet air purifier of the present invention also includes a second working state, in which the user can lift the diffusion table top 1 through the sliding assembly for vertical lifting of the circular table. When the diffusion table top 1 drives the circular table to rise, the distance between the concave cone 14 and the air outlet 3 becomes larger to H2. After the distance is widened, the ability of the concave cone 14 to guide the air flow laterally is significantly reduced, resulting in the concave cone 14 cooperating with the air outlet 3 to form a second working state in which the vertical air flow of the air outlet 3 is guided to diffuse along the concave cone 14 to the surroundings and then continues to rise (equivalent to the vertical air flow bypassing the concave cone 14 and the diffusion table top 1 and then slightly diffusing, and then continuing to be emitted upward in the vertical direction. At this time, the cooperation structure of the concave cone 14 and the air outlet 3 basically cannot change the main flow direction of the air flow). In the second working state, H>ws. As the distance H between the bottom surface of the diffusion table top 1 and the air outlet 3 increases, the ability of the concave cone 14 to guide the air flow laterally is reduced. In this mode, the focus is more on directly emitting filtered air to the human body's breathing height, similar to a traditional floor-standing air purifier. Users may breathe more filtered clean air, enhancing the user experience.

[0071] In summary, the purpose of the present invention is to provide a pet air purifier that can more effectively expand the range of air flow, enhance the effect of inhaling pet hair on the ground, optimize the air purification capacity, and improve the user experience of pet owners.

[0072] The above is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention should not be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
