Description

Technical Field

[0001] This utility model relates to the field of air purifiers, and in particular to a pet air purifier with circulating air intake. Background Technology

[0002] Air purifiers remove particulate matter, odors, harmful gases, and microorganisms from the air, ultimately improving indoor air quality. During operation, a fan generates negative pressure, drawing polluted indoor air into the purifier through the inlet. The air then flows through internal purification modules (such as filters, electrodes, and photocatalytic devices), where pollutants are intercepted, adsorbed, or decomposed. Finally, the purified air is expelled back into the room through the outlet, creating a cycle that gradually reduces the concentration of indoor pollutants.

[0003] Existing air purifiers typically have their air inlets located on the side or bottom of the unit, while the air outlets are usually located on the top. When the air purifier is in a pet's activity area, dust and pet hair are present on the ground. When the air inlet draws air into the purifier, the large amount of accumulated pet hair can easily clog the inlet, preventing air from entering the unit smoothly. This reduces air purification efficiency and affects the normal operation of the air purifier. To solve this problem, this application provides a pet air purifier with circulating air intake. Utility Model Content

[0004] To address the aforementioned issues, this application provides a pet air purifier with circulating air intake.

[0005] To achieve the above objectives, this application provides the following technical solution: a pet air purifier with circulating air intake, comprising a housing structure and a filter disposed inside it, the housing structure comprising a protective cover and an air outlet cover fixed below the protective cover, a partition fixed inside the protective cover, a filter and a fan respectively installed on the upper and lower parts of the partition, the fan being located inside the air outlet cover, and the air inlet of the fan being connected to the filter.

[0006] The filter is fixed with a cover plate at the top. The opening of the cover is connected to the cover plate by two symmetrically distributed air inlet covers. When the fan is running, the air outside the cover passes through the air inlet covers and enters the inside of the cover. After being filtered by the filter, it is discharged through the air outlet of the fan to the inside of the air outlet cover, and then discharged to the outside of the air outlet cover.

[0007] Furthermore, both of the air inlet covers extend to form horizontally distributed mounting flanges at their bottom ends, and a pair of support plates are fixed to the outside of each cover.

[0008] Each of the aforementioned pallets is rotatably mounted with a pair of sleeve rods, each sleeve rod being connected to a positioning rod via an elastic structure. The positioning rod extends along the arcuate trajectory of the mounting flange to form a locking strip. A pressure rod is fixed to the end of the locking strip away from the positioning rod. When the air inlet hood is installed in the relative space between the cover plate and the hood opening, the mounting flange abuts against the pallet, and the pressure rod passes through the mounting flange.

[0009] Furthermore, the elastic structure includes a pressure spring and a guide rod disposed inside the pressure spring. The two ends of the pressure spring are fixed to the inner top wall of the positioning rod and the inner bottom wall of the sleeve rod, respectively. The bottom end of the guide rod is fixed to the inner bottom wall of the sleeve rod, and the top end of the guide rod extends through the positioning rod and above it. When the locking bar is lifted, the pressure rod disengages from the mounting flange, the positioning rod moves away from the sleeve rod along the surface of the guide rod, and the pressure spring undergoes adaptive deformation.

[0010] Furthermore, each of the trays has two downward-facing extension rods fixed to its bottom end, and each extension rod has a threaded insertion rod at its bottom end.

[0011] Two symmetrically distributed air guide covers are provided on the lower outer side of each air outlet cover. Two positioning sleeves are embedded on the surface of each air guide cover, and the insertion rods extend through the positioning sleeves to their lower sides.

[0012] Furthermore, each of the insert rods is fixed with an intercepting ring at its bottom end, and each of the intercepting rings is fixed with a pressure spring II at its top end. Each of the pressure spring II is fixed with a pressure block at its top end. The pressure block abuts against the bottom end of the positioning sleeve. When the flow guide is pressed, the positioning sleeve squeezes the pressure block down, and the pressure spring II makes an adaptive deformation, so that the insert rod is exposed above the flow guide.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] This invention allows air outside the protective cover to pass through the inlet hood and enter the interior of the cover. After being filtered, the air is discharged through the fan outlet to the inside of the outlet hood, and then discharged to the outside again. When dust and animal hair are present on the ground, they can be blown up by the airflow discharged from the outlet hood and pass through the inlet hood again into the interior of the cover. With the circulation and purification of the air, it has a good adsorption and purification effect on animal hair and dust in the air, improving the working quality of the air purifier.

[0023] 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.

[0024] Example 1: Reference Figure 1-3 The pet air purifier with circulating air intake shown includes a housing structure and a filter 3 disposed inside it. The housing structure includes a protective cover 1 and an air outlet cover 2 fixed below the protective cover 1. A partition 5 is fixed inside the protective cover 1. The filter 3 and a fan 4 are respectively installed on the upper and lower parts of the partition 5. The fan 4 is located inside the air outlet cover 2, and the air inlet of the fan 4 is connected to the filter 3.

[0025] The top of the filter 3 is fixed with a cover plate 6. The opening of the cover 1 is connected to the cover plate 6 by two symmetrically distributed air inlet hoods 7. When the fan 4 is running, the air outside the cover 1 passes through the air inlet hood 7 and enters the interior of the cover 1. After being filtered by the filter 3, it is discharged through the air outlet of the fan 4 to the inside of the air outlet hood 2, and then discharged to the outside of the air outlet hood 2.

[0026] When dust and pet hair are present on the ground, they are blown away by the airflow exhausted to the outside by the exhaust hood 2. Subsequently, the dust and pet hair floating in the air can pass through the intake hood 7 and enter the protective cover 1 again under the suction force of the fan 4 when it is turned on. With the circulation and purification of the air, it has a good adsorption and purification effect on pet hair and dust in the air, improving the working quality of the air purifier and making it suitable for environments where pets live.

[0027] Since animal hair tends to clump together on the ground, in order to prevent clumps of hair from entering the protective cover 1 and causing blockage on the surface of the filter 3, in this invention, the air inlet cover 7 can intercept larger clumps of hair. Furthermore, the air inlet cover 7 is a detachable structure. When the clumps of hair intercepted on its surface accumulate to a certain volume, the detachable air inlet cover 7 can be removed to centrally transfer and clean the hair. This ensures the working efficiency of the filter 3 while also facilitating centralized cleaning and transfer of the hair.

[0028] like Figure 3 As shown, both air inlet covers 7 extend horizontally from their bottom ends to form horizontally distributed mounting flanges 71, and a pair of support plates 14 are fixed to the outside of each cover 1. A pair of sleeve rods 15 are rotatably mounted on each support plate 14. Each sleeve rod 15 is connected to a positioning rod 13 via an elastic structure. The positioning rod 13 extends along the arcuate trajectory of the mounting flange 71 to form a locking strip 12. A pressure rod 11 is fixed to the end of the locking strip 12 away from the positioning rod 13. When the air inlet cover 7 is installed in the space between the opening of the cover plate 6 and the cover 1, the mounting flange 71 abuts against the support plate 14, and the two pressure rods 11 connected to the two locking strips 12 penetrate through the mounting flange 71. A locking operation is performed on the mounting flange 71 to maintain the stability of the mounting flange 71 and the air inlet cover 7.

[0029] like Figure 4As shown, the elastic structure includes a pressure spring 17 and a guide rod 16 located inside the pressure spring 17. The two ends of the pressure spring 17 are fixed to the inner top wall of the positioning rod 13 and the inner bottom wall of the sleeve rod 15, respectively. The bottom end of the guide rod 16 is fixed to the inner bottom wall of the sleeve rod 15, and the top end of the guide rod 16 extends through the positioning rod 13 and above it. When the locking bar 12 is raised, the pressure rod 11 disengages from the mounting flange 71, and the positioning rod 13 moves along the surface of the guide rod 16 away from the sleeve rod 15. The pressure spring 17 undergoes an adaptive deformation. Subsequently, the locking bar 12 can be rotated, causing the pressure rod 11 to disengage from the mounting flange 71, releasing its restriction on the mounting flange 71. This allows for the easy removal of the air inlet cover 7, facilitating the cleaning of clumps of hair on the surface of the air inlet cover 7.

[0030] The present invention has two air inlet covers 7. When one air inlet cover 7 is cleaned, the other air inlet cover 7, located on one side of the protective cover 1, can still perform filtration, thus ensuring the purification efficiency of the air purifier.

[0031] Example 2: Based on Example 1, such as Figure 5 , Figure 6 As shown, two downward-facing extension rods 141 are fixed to the bottom of each support plate 14, and each extension rod 141 is threadedly connected to a plug rod 142. Two symmetrically distributed guide hoods 8 are provided on the lower outer side of each air outlet hood 2. The guide hoods 8 allow part of the air discharged from the air outlet hood 2 to flow precisely to the ground, so as to quickly blow up the dust and pet hair on the ground near the air purifier, and then facilitate the floating dust and pet hair to be quickly collected on the surface of the filter 3 through the air inlet hood 7.

[0032] Each air deflector 8 has two positioning sleeves 81 embedded on its surface. See Figure 6 As shown, the insert rods 142 both extend through the positioning sleeve 81 to its lower part. The two insert rods 142 are positioned by penetrating the deflector 8, which can improve the stability of the deflector 8, prevent the deflector 8 from shaking or shifting, and maintain the stability of the deflector 8 during use.

[0033] Each insertion rod 142 has an intercepting ring 143 fixed to its bottom end, and a pressure spring 144 fixed to the top of each intercepting ring 143. A pressure block 145 is fixed to the top of each pressure spring 144, and the pressure block 145 abuts against the bottom end of the positioning sleeve 81. Depending on the work requirements, if it is necessary to disassemble the flow guide 8, the flow guide 8 can be pressed, causing the positioning sleeve 81 to press down the pressure block 145. The pressure spring 144 then deforms accordingly, and the insertion rod 142 protrudes above the flow guide 8. This creates a space above the flow guide 8 where the insertion rod 142 can be disengaged from the extension rod 141, reducing the inconvenience of disassembly operations below the flow guide 8 and improving portability during disassembly.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
