Description

Technical Field

[0001] This application relates to the field of electrical technology, and in particular to a pet air purifier. Background Technology

[0002] With the booming development of the pet economy, the demand for pet air purifiers is increasing. Pet-owning families are eager to own pet air purifiers that can effectively address issues such as pet odors, hair buildup, and allergens, ensuring that people and pets share a healthy and comfortable environment.

[0003] To meet this demand, some pet air purifiers specifically designed for pets have appeared on the market. These products typically have a support stand on top to attract pets to stay on it. Air inlets are located on the side walls, and air outlets are near the support stand to absorb and purify pet hair and odors. However, currently, the air inlets of pet air purifiers are all concentrated on the side, which fails to effectively absorb and clean up hair and dust scattered and accumulated on the ground around the purifier. This results in a messy floor, and the hair stirred up by people or animals during activity cannot be cleaned up properly. Utility Model Content

[0004] Therefore, it is necessary to improve the air inlet of common pet air purifiers to solve the problems of poor pet hair collection and pet hair flying everywhere, and to provide a better pet air purifier.

[0005] This application provides a pet air purifier, including: a head unit having a support platform at the top and a housing at the bottom, a first air outlet being formed between the support platform and the housing, and the upper surface of the support platform being recessed downward for the pet to squat and lie down;

[0006] The unit has a cover, a base located at the end of the cover away from the head, and a main air inlet, with the main air inlet located between the base and the cover;

[0007] A filter device, located inside the machine body, is used to filter the airflow;

[0008] An air supply device, installed inside the housing, is used to generate airflow that passes sequentially through the main air inlet, the filter device, and the first air outlet;

[0009] The main air inlet extends circumferentially around the axis of the base, which has a guide surface for guiding airflow from the main air inlet, and the guide surface contracts inward from top to bottom.

[0010] According to one embodiment of this application, the drainage surface is an annular arc surface formed by rotating an arc around the axis of the base, and the annular arc surface protrudes outward.

[0011] According to one embodiment of this application, the main air inlet is located between the lower edge of the cover and the airflow surface of the base, with the lower edge of the cover close to the ground.

[0012] According to one embodiment of this application, the lower edge of the cover extends outward from top to bottom.

[0013] According to one embodiment of this application, the lower edge protrudes toward the drainage surface, forming a funnel-shaped flare together with the drainage surface.

[0014] According to one embodiment of this application, the vertical distance between the lower edge and the ground is X1, the horizontal distance between the lower edge and the drainage surface is X2, and the ratio of the vertical distance X1 to the horizontal distance X2 is 0.5-2.2.

[0015] According to one embodiment of this application, the fuselage also includes a secondary air inlet, which is formed on the cover.

[0016] According to one embodiment of this application, the air intake area of ​​the main air intake is larger than that of the secondary air intake.

[0017] According to one embodiment of this application, the air intake area of ​​the main air intake is 2-5 times that of the secondary air intake.

[0018] According to one embodiment of this application, the base includes a base and the airflow surface is the wall portion through which the airflow flows on the base.

[0019] According to one embodiment of this application, the minimum diameter of the drainage surface is greater than or equal to the diameter of any other part of the base.

[0020] According to one embodiment of this application, the base further includes a support portion and a connecting portion. The support portion is used to support the cover and is detachably connected to the cover. The connecting portion is used to connect the base portion and the support portion.

[0021] According to one embodiment of this application, the main air inlet is surrounded by a base and a support, and extends around the base in a ring shape; the connecting part divides the main air inlet into several sub-air inlets.

[0022] According to one embodiment of this application, the connecting portion extends radially outward and obliquely upward from the base to the support portion.

[0023] The main air intake of the aforementioned pet air purifier is located around the base of the unit, placing it at the bottom of the device and as close to the ground as possible. When the pet air purifier is turned on, a strong negative pressure zone is formed near the main air intake. Hair and dust from the surrounding ground are quickly drawn into the pet air purifier through the main air intake under the suction force, improving the pet air purifier's cleaning efficiency for pollutants on the surrounding ground.

[0063] An embodiment of this application provides a pet air purifier, including a head unit 100, a body 200, an air supply device 300, and a filter device 400.

[0064] The unit includes a head unit 100 with a first chamber 110 and a first air outlet 120 communicating with the first chamber 110. Optionally, a support platform 130 is provided on the top of the head unit 100. The body 200 has a second chamber 210 and a main air inlet 220 communicating with the second chamber 210. The second chamber 210 is connected to the first chamber 110. The body 200 and the head unit 100 are detachably connected. Specifically, the upper part of the body 200 and the lower part of the head unit 100 are connected. A locking mechanism can be provided at the top of the body 200 and the bottom of the head unit 100 to achieve the detachable connection. An air supply device 300 is installed in the first chamber 110 and is used to generate purified airflow that passes sequentially through the main air inlet 220, the second chamber 210, the first chamber 110, and the first air outlet 120. A filter device 400 is installed in the second chamber 210 and is used to filter the airflow generated by the air supply device 300.

[0065] Optionally, the air supply device 300 includes a motor 310 and a fan wheel 320, wherein the motor 310 is vertically arranged and fixedly connected to the head 100, and the fan wheel 320 is fixedly connected to the motor shaft of the motor 310. The motor 310 is adapted to drive the fan wheel 320 to rotate axially, thereby forming an airflow.

[0066] Optionally, the pet air purifier also includes a temperature control device 500, which is installed on the head unit 100 and is used to heat and / or cool the support platform 130.

[0067] Optionally, all electrical components of the pet air purifier are located in the head unit 100, including a motor 310 and a temperature control device 500. Further, the aforementioned electrical components also include other electrical parts of the pet air purifier besides the motor 310 and the temperature control device 500.

[0068] This embodiment of the pet air purifier purifies the air by utilizing the airflow generated by the air supply device 300 and the filtration effect of the filter device 400. Furthermore, the support platform 130 mounted on top of the unit 100 can be used to support the pet, allowing it to rest or play on the platform. When the temperature control device heats or cools the support platform 130, it can adjust it to a suitable temperature to increase the pet's comfort and encourage it to stay there.

[0069] In addition, the first air outlet 120 is located at the head 100, making the first air outlet 120 adjacent to the support platform 130, thereby making the air near the support platform 130 cleaner and further improving the comfort of the pet when it stays there.

[0070] In addition, pets inevitably shed hair. When a pet stays on the support platform 130, the shed hair, odors, allergens, etc. can be promptly removed by the pet air purifier, which can effectively improve indoor air purification efficiency and improve indoor air quality.

[0071] Furthermore, in this embodiment of the pet air purifier, the support platform 130 is set on the top of the head unit 100. Compared with other forms, in addition to meeting the pet's need to stay and rest, it also has the advantage of making it easier for the pet to jump up and down, which helps to increase the pet's interest in using it.

[0072] In addition, all electrical components of the pet air purifier are located in the head unit 100. After the head unit 100 is separated from the body 200, the body 200 does not contain electrical components, making it easy to clean the body 200 and the filter device 400 inside the body 200. This makes it easier to maintain the cleanliness and filtration effect of the pet air purifier during long-term use, further increasing the pet's willingness to stay.

[0073] Combination Figure 3-1 , Figure 3-2 , Figure 4-1 as well as Figure 4-2 In some embodiments, the temperature control device 500 is configured to adjust the temperature based on the ambient temperature and / or the temperature of the support platform 130, so that the temperature of the support platform 130 is within a preset range.

[0074] Optionally, the temperature control device 500 includes a semiconductor temperature control chip 510, a temperature sensor, a temperature and humidity sensor, and a control board.

[0075] The semiconductor temperature control chip 510 is installed inside the head 100 and is thermally connected to the support platform 130. The semiconductor temperature control chip 510 can be in direct contact with the bottom surface of the support platform 130 or indirectly contacted through a good thermal conductor (such as metal or thermal grease), thereby achieving a thermally conductive connection between the semiconductor temperature control chip 510 and the support platform 130.

[0076] Temperature and humidity sensors are installed inside the machine head 100. The temperature sensor is used to acquire temperature information of the support platform 130. The temperature sensor can be a contact sensor; for example, the sensor's acquisition end contacts the bottom surface of the support platform 130, thereby directly and effectively acquiring the temperature information of the support platform 130. The humidity sensor is used to acquire ambient temperature and can be installed on the side wall or other locations of the machine head 100.

[0077] The control board is connected to the temperature sensor, the temperature and humidity sensor and the semiconductor temperature control chip 510 respectively. The control board is used to control the operation of the semiconductor temperature control chip 510.

[0078] In some embodiments, the temperature control device 500 is configured to perform heating or cooling control based on the temperature information of the support platform 130 and the ambient temperature information. Taking the temperature control device 500 including a semiconductor temperature control chip 510, a temperature sensor, a temperature and humidity sensor, and a control board as an example, the control board controls the semiconductor temperature control chip 510 to heat or cool based on the detection signals of the temperature sensor and the temperature and humidity sensor.

[0079] For example, the control board is configured to perform an initial temperature judgment after the pet air purifier is turned on, and control the semiconductor temperature control chip 510 to heat or cool according to the initial judgment rules. The initial temperature judgment rules include:

[0080] If the ambient temperature data is greater than or equal to the first preset temperature and the surface temperature data of the support platform 130 is greater than or equal to the second preset temperature, the semiconductor temperature control chip 510 is controlled to start the cooling mode. At this time, the upper surface of the semiconductor temperature control chip 510 is the cold surface and the lower surface is the hot surface.

[0081] If the ambient temperature is greater than or equal to the first preset temperature and the surface temperature of the support platform 130 is less than the second preset temperature, the semiconductor temperature control chip 510 is turned off.

[0082] If the ambient temperature is determined to be less than the first preset temperature and the surface temperature of the support platform 130 is less than or equal to the third preset temperature, the semiconductor temperature control chip 510 is controlled to start the heating mode. At this time, the upper surface of the semiconductor temperature control chip 510 is the hot surface and the lower surface is the cold surface.

[0083] If the ambient temperature is determined to be lower than the first preset temperature and the surface temperature of the support platform 130 is determined to be higher than the third preset temperature, the semiconductor temperature control chip 510 is controlled to shut down.

[0084] The first preset temperature is less than the second preset temperature but greater than the third preset temperature.

[0085] Optionally, the first preset temperature is 25℃, the second preset temperature is 27℃, and the third preset temperature is 22℃.

[0086] Furthermore, the control board is configured to perform cyclic judgments after completing the initial temperature judgment, and control the semiconductor temperature control chip 510 to heat or cool according to the cyclic judgment rules. The cyclic judgment rules include:

[0087] If the ambient temperature data is greater than or equal to the fourth preset temperature and the surface temperature data of the support platform 130 is greater than or equal to the third preset temperature, control the semiconductor temperature control chip 510 to start the cooling mode until the surface temperature data of the support platform 130 drops below the third preset temperature and then shuts off.

[0088] If the ambient temperature data is greater than or equal to the first preset temperature and less than the fourth preset temperature, and the surface temperature data of the support platform 130 is greater than or equal to the second preset temperature, the semiconductor temperature control chip 510 is controlled to start the cooling mode until the surface temperature data of the support platform 130 drops below the second preset temperature and then the operation is turned off.

[0089] If the ambient temperature is greater than the third preset temperature and less than the first preset temperature, and the surface temperature of the support platform 130 is less than or equal to the third preset temperature, the semiconductor temperature control chip 510 is controlled to start the heating mode until the surface temperature of the support platform 130 rises above the third preset temperature and then the operation is turned off.

[0090] If the ambient temperature is less than the third preset temperature and the surface temperature of the support platform 130 is less than or equal to the first preset temperature, the semiconductor temperature control chip 510 is controlled to start the heating mode until the surface temperature of the support platform 130 rises above the first preset temperature before shutting down.

[0091] The fourth preset temperature is greater than the second preset temperature. For example, the fourth preset temperature is 28℃.

[0092] Furthermore, the control board is configured to perform a cyclic judgment every preset time interval after the initial judgment is completed, and control the semiconductor temperature control chip 510 to heat or cool according to the cyclic judgment rules, so as to maintain the surface temperature of the support stage 130 in dynamic balance.

[0093] Optional preset durations include 20s, 30s, and 40s.

[0094] In summary, by employing a temperature control device 500 that includes a semiconductor temperature control chip 510, a temperature sensor, a temperature and humidity sensor, and a control board, the pet air purifier achieves intelligent constant temperature control of the support platform 130, improving the pet's comfort and the practicality of the pet air purifier.

[0095] The semiconductor temperature control chip 510 in this embodiment is a cooling device based on the Peltier effect. When direct current passes through a thermocouple made of two different semiconductor materials connected in series, heat can be absorbed and released at the two ends of the thermocouple, respectively, achieving the purpose of cooling. The semiconductor temperature control chip 510 can quickly perform cooling or heating operations according to the instructions of the control board, thereby effectively regulating the temperature of the pet seat and keeping it within a suitable range. In conjunction with a temperature sensor, the control board can monitor the temperature information of the support platform 130 in real time and adjust the working state of the semiconductor temperature control chip 510 accordingly to achieve precise temperature control. Compared with traditional cooling or heating methods, the semiconductor temperature control chip 510 has advantages in energy efficiency, reducing energy consumption while ensuring temperature control effects, meeting the requirements of energy conservation and environmental protection.

[0096] In some embodiments, the temperature control device 500 further includes a heat sink 530, which is used to dissipate heat when the temperature control device 500 cools or heats the support platform 130. Taking a semiconductor temperature control chip 510 as an example, the upper side of the semiconductor temperature control chip 510 contacts the support platform 130, and the lower side of the semiconductor temperature control chip 510 contacts the heat sink 530. When the temperature control device 500 cools the support platform 130, the upper surface of the semiconductor temperature control chip 510 is the cold surface, and the lower surface is the hot surface. The temperature of the hot surface needs to be dissipated in time. The heat sink 530 in this embodiment can conduct the heat of the lower surface of the semiconductor temperature control chip 510 away in time, thereby ensuring the cooling effect of the temperature control device 500 on the support platform 130.

[0097] Optionally, the heat sink 530 has multiple parallel and spaced fins on the side opposite to the semiconductor temperature control chip 510 (i.e., the lower side of the heat sink 530) to increase the contact area between the heat sink 530 and the air and improve the heat dissipation effect.

[0098] Optionally, the heat sink 530 is located inside the casing 200, and the heat dissipation effect can be improved by the airflow generated by the air supply device 300.

[0099] In some embodiments, the temperature control device 500 further includes a heat dissipation duct 520 located within the housing 200, the heat dissipation duct 520 connecting the first chamber 110 and the first air outlet 120, and the air supply device 300 is also used to form an airflow through the heat dissipation duct 520, at least a portion of the heat sink 530 being located within the heat dissipation duct 520.

[0100] In this embodiment, the heat sink 530 serves as the medium for heat conduction, and its large heat dissipation surface is located in the heat dissipation duct 520, allowing it to fully contact the air. This design significantly improves the heat dissipation efficiency of the temperature control device 500, ensuring the stability and reliability of the equipment under long-term, high-load operation. Part of the airflow generated by the air supply device 300 passes through the heat dissipation duct 520, exchanges heat with the heat sink 530, and then flows out from the first air outlet 120, thereby carrying away the heat accumulated on the heat sink 530 when the semiconductor temperature control chip 510 cools the support platform 130.

[0101] The heat sink 530 is tightly connected to the semiconductor temperature control chip 510, ensuring rapid heat transfer from the semiconductor temperature control chip 510 to the heat sink 530. Simultaneously, the arrangement of the heat sink 530 within the heat dissipation duct 520 contributes to uniform heat conduction, preventing localized overheating or uneven temperature distribution. This temperature uniformity is crucial for protecting sensitive components within the temperature control device 500 and extending the device's lifespan. By integrating the heat dissipation duct 520, heat sink 530, and semiconductor temperature control chip 510 into the head unit 100, a compact structure is achieved. This not only saves space but also makes the temperature control device 500 more flexible and convenient to install and deploy.

[0102] Furthermore, the inlet of the heat dissipation duct 520 faces the outlet of the air supply device, which helps to reduce airflow resistance and improve heat dissipation efficiency.

[0103] The efficient heat dissipation design of the 520 cooling duct enables the temperature control device 500 to better maintain stable internal temperatures, thus providing a more stable and reliable operating environment for the protected electronic equipment or components. This helps improve the performance and stability of the entire system, extend the service life of the equipment, and reduce the failure rate caused by overheating.

[0104] Combination Figure 2-1 and Figure 2-2In some embodiments, the air supply device 300 further includes a motor bracket 330, which includes a support ring 331 and a frame 332 located inside the support ring 331. The frame 332 and the support ring 331 are fixedly connected by multiple stiffeners 333. The head unit 100 also includes a housing 140, with a support platform 130 fixedly disposed above the housing 140. The support ring 331 is fixedly connected to the housing 140. The first chamber 110 includes a first sub-chamber 111, an air outlet channel 112, and a second sub-chamber 113. The portion of the housing 140 located below the frame 332 constitutes the first sub-chamber 111. The frame 332 and the support ring 331 form the air outlet channel 112. The frame 332 and the support platform 130 form the second sub-chamber 113. The first sub-chamber 111 is connected to the first air outlet 120 through the air outlet channel 112. The motor 310 is vertically mounted in the second sub-chamber 113. The rotor of the motor 310 extends from the lower side of the frame 332 to the first sub-chamber 111. The impeller 320 is mounted in the first sub-chamber 111 and connected to the rotor of the motor 310. When the motor 310 drives the impeller 320 to rotate, it generates airflow that passes sequentially through the first sub-chamber 111 and the air outlet 112 and flows out through the first air outlet 120.

[0105] The heat dissipation duct 520 includes an air intake section 521 and a heat exchange section 522 that are interconnected. The heat exchange section 522 is located above the second sub-chamber 113 and is used to accommodate part or all of the heat sink 530. The heat exchange section 522 is horizontally arranged, with one end connected to the first air outlet 120 and the other end connected to the air intake section 521. The air intake section 521 is inclined downwards, with its upper end connected to the heat exchange section 522, and its lower end extending from an opening in the side wall of the frame 332 to the air outlet 112. This allows part of the airflow generated by the air supply device 300 to enter the air intake section 521 when it reaches the air outlet 112. Guided by the inner wall of the air intake section 521, the airflow enters the heat exchange section 522 and flows horizontally under the guidance of the heat sink 530. It then continues to flow and exits through the first air outlet 120.

[0106] The heat dissipation duct 520 with the above-described structure allows the airflow generated by the air supply device 300 to easily enter the air intake section 521, reducing air resistance and increasing the air intake volume. Furthermore, the structure of the heat dissipation duct 520 reduces noise when guiding airflow to the heat sink 530 for heat dissipation, improving the comfort of the pet. In addition, the heat sink 530 exchanges heat with the air within the heat exchange section 522, utilizing high-speed airflow to improve heat exchange efficiency and preventing the heat generated by the semiconductor temperature control chip 510 from adversely affecting other components of the pet air purifier.

[0107] Optionally, a heat dissipation gap is formed between adjacent fins of the heat sink 530, and the extension direction of the heat dissipation gap is the same as the extension direction of the heat exchange section 522, so that the air in the heat exchange section 522 can pass through the heat dissipation gap, thereby enhancing the heat dissipation effect of the heat sink 530 and further reducing air resistance.

[0108] Combination Figure 2-2 Figure 4-1 and Figure 4-2 In some embodiments, the support platform 130 includes a first bracket 131, a cover 133, and a platform 134. The first bracket 131 is located on the top of the machine head 100, the cover 133 is located inside the first bracket 131 and is fixedly connected to the first bracket 131, and the platform 134 is fixedly connected to the cover 133.

[0109] For example, the housing 140 includes an inner shell 141, an outer shell 142, and a top shell 143. Both the inner shell 141 and the outer shell 142 are cylindrical structures. A bent section is provided on the inner bottom side of the outer shell 142, and the top end of the bent section is fixedly connected to the bottom end of the inner shell 141. The top shell 143 is an annular structure, with its inner edge fixedly connected to the top end of the inner shell 141 and its outer edge fixedly connected to the top end of the outer shell 142. The first support 131 includes a funnel-shaped support body and multiple legs located on the lower side of the support body. The bottom ends of the legs are fixedly connected to the top shell 143. An annular flow channel 138 is formed between the lower side of the support body and the top shell 143. The inner side of the flow channel 138 connects to an air outlet channel 112, and the outer side connects to a first air outlet 120. The heat exchange section 522 is connected to the first air outlet 120 through the flow channel 138.

[0110] Optionally, the lower side of the bracket body and the upper side of the top shell 143 are provided with inclined arc surfaces. The airflow channel 138 is inclined upward from the side connected to the air outlet channel 112 to the side connected to the first air outlet 120, so that the airflow has less resistance when it flows out, and the airflow flowing out of the first air outlet 120 is inclined upward, making the pet located above the support platform 130 more comfortable.

[0111] Combination Figure 4-2 and Figure 5-2 For example, the cover 133 has a funnel-shaped structure, the inner side of the cover 133 is provided with a first stepped surface, the platform 134 is disc-shaped, the edge of the platform 134 overlaps the first stepped surface and is fixedly connected to the cover 133, and the top outer side of the cover 133 is fixedly connected to the top edge of the first support 131.

[0112] For example, the height of the platform 134 is less than the height of the top of the first support 131, thereby forming a groove on the upper side of the support platform 130 to prevent the pet from falling off when resting on the support platform 130. The diameter D1 of the platform 134 is less than the maximum outer diameter D2 of the first support 131 to increase the comfort of the pet.

[0113] Alternatively, the diameter D1 of the platform 134 is between 220mm and 280mm, for example, 220mm, 250mm, or 280mm. Within this size range, it is just right for a pet to lie on, while avoiding the space-consuming nature of an excessively large size.

[0114] Combination Figure 4-3 Optionally, the lower end of the bracket body is provided with a hollow hole, and the lower end of the bracket body is fixedly connected to the upper end of the frame 332.

[0115] In some embodiments, the first bracket 131, the cover plate, and the platform 134 form a mounting cavity 137, which is located above the second sub-chamber 113. At least a portion of the heat dissipation duct 520 and / or the heat sink 530 is located within the mounting cavity 137. For example, the entire heat dissipation duct 520 and the heat sink 530 are located within the mounting cavity 137. By placing at least a portion of the structure of the heat dissipation duct 520 and / or the heat sink 530 within the mounting cavity 137, improved heat dissipation efficiency, optimized space utilization, and enhanced structural compactness are achieved.

[0116] Optionally, the upper side of the semiconductor temperature control chip 510 contacts and engages with the lower side of the platform 134. The upper end of the heat sink 530 is adapted to the opening on the upper side of the heat dissipation duct 520, and extends from the opening on the upper side of the heat dissipation duct 520 to the outside of the heat dissipation duct 520, and the upper end face of the heat sink 530 is in contact with the lower side of the semiconductor temperature control chip 510. The heat sink 530 is fixedly connected to the platform 134, for example, by means of screws or clips.

[0117] Optionally, the first bracket 131 is provided with a second air outlet 132, and the heat dissipation duct 520 is connected to the first air outlet 120 through the second air outlet 132. In other words, the second air outlet 132 is connected to both the first air outlet 120 and the heat dissipation duct 520. The second air outlet 132 can be located on the side wall of the first bracket 131, with the exhaust port of the heat dissipation duct 520 facing the second air outlet 132. The second air outlet 132 is connected to the first air outlet through a guide channel.

[0118] Optionally, a filter screen is provided at the junction of the air guide channel 138 and the air outlet channel 112 and / or at the second air outlet 132. Preferably, filters screens are provided at both the junction of the air guide channel 138 and the air outlet channel 112 and at the second air outlet 132. The filters can prevent debris from entering the machine head 100 in the reverse direction through the air guide channel 138 and the second air outlet 132.

[0119] In some embodiments, the support platform 130 further includes a heat insulation member 135, which is located within the mounting cavity. The upper side of the heat insulation member 135 contacts and engages with the platform 134. The inner side of the cover 133 is provided with a first stepped surface, and the edge of the heat insulation member 135 overlaps with a second stepped surface. The heat insulation member 135 has a through hole 136, and the semiconductor temperature control chip 510 is located within the through hole 136. By providing the heat insulation member 135, heat loss during the cooling process is significantly reduced, allowing the semiconductor temperature control chip 510 to perform cooling operations more concentratedly and efficiently, thereby improving the overall cooling efficiency. At the same time, the heat insulation member 135 can also reduce noise, block vibration, and increase comfort.

[0120] Optionally, the insulation component 135 includes a foam board that contacts and mates with the platform 134, and has through holes 136. The foam board is lightweight, high-strength, and possesses excellent thermal and sound insulation properties, effectively meeting the insulation requirements of the support platform 130 while reducing material costs and improving the product's cost-effectiveness. Furthermore, the foam board is easy to process and mold, facilitating customization according to actual needs and further enhancing design flexibility.

[0121] In some embodiments, the platform 134 is made of a metal plate, preferably an aluminum plate. The metal plate, particularly the aluminum plate, has good thermal conductivity, enabling it to quickly transfer the cold or heat generated by the semiconductor temperature control chip 510 to the entire surface of the platform 134, thereby achieving more efficient and uniform heat dissipation. This is especially true when the semiconductor temperature control chip 510 is located within the through hole 136 of the heat insulation member 135 and is in close contact with the aluminum plate.

[0122] Upon contact, the high thermal conductivity of aluminum ensures that cold or heat is rapidly dissipated, preventing heat buildup and thus improving overall heat dissipation efficiency. Furthermore, aluminum is lighter than other metals, making the equipment more portable and easier to handle and install. Aluminum also possesses excellent corrosion resistance, resisting common environmental corrosive factors such as moisture and oxidation, thereby extending the equipment's lifespan.

[0123] Combination Figure 1 In some embodiments, the pet air purifier also includes an aromatherapy stick 600. By integrating the aromatherapy stick 600 into the pet air purifier, not only is the user's need for fresh air met, but the soothing effect of aromatherapy is also added, thus improving the overall user experience.

[0124] The aroma wand 600 is detachably connected to the first bracket 131. This detachable design allows users to choose different essential oils according to their personal preferences, achieving a personalized aromatherapy experience. Furthermore, the detachable connection between the aroma wand 600 and the first bracket 131 not only maintains the compact structure of the pet air purifier but also facilitates the replacement and maintenance of the aroma wand 600.

[0125] One end of the aromatherapy stick 600 is located inside the mounting cavity, and the other end extends to the outside of the first bracket 131. The end of the aromatherapy stick 600 located outside the first bracket 131 forms an aromatherapy outlet, which is adjacent to the first air outlet 120. The proximity of the aromatherapy outlet to the first air outlet 120 allows the airflow generated during air purification to effectively disperse the aromatherapy essential oils, improving the coverage and dispersion efficiency of the aromatherapy. Through the airflow, the aromatherapy essential oils can fully mix with the purified air, ensuring that users can enjoy fresh air while also experiencing the soothing aroma of the aromatherapy.

[0126] Optionally, the aroma stick 600 is located on the air outlet path of the second air outlet 132, which is beneficial to improve the evaporation effect by utilizing the blowing and heating effect of the air flowing out of the second air outlet 132.

[0127] It is worth noting that the aroma stick 600 in this embodiment can be replaced or have essential oil added by disassembly. Alternatively, essential oil can be dripped onto the aroma outlet through the first air outlet 120, allowing the aroma cotton of the aroma stick 600 to absorb and store the essential oil, thereby achieving reuse.

[0128] Combination Figure 16 In some embodiments, the pet air purifier further includes a bouncer 610 and a spring block 620, wherein the bouncer 610 is installed in the mounting cavity and has a telescopic end. The spring block 620 is slidably installed in the mounting cavity and is located between the end of the aromatherapy stick 600 away from the aromatherapy outlet and the telescopic end.

[0129] In this embodiment, the rebound mechanism 610 and the spring block 620 can increase the stability of the aromatherapy stick 600 during installation. Furthermore, by setting the rebound mechanism 610 and the spring block 620, the aromatherapy stick 600 can be quickly disassembled. Specifically, when the aromatherapy stick 600 needs to be replaced, the user can press the aromatherapy stick 600 inwards to drive the spring block 620 to slide in the same direction. At this time, the spring block 620 drives the telescopic end of the rebound mechanism 610 to retract, unlocking the telescopic end of the rebound mechanism 610. This, in turn, pushes the spring block 620 and the aromatherapy stick 600 outwards, causing the aromatherapy outlet end of the aromatherapy stick 600 to protrude from the outer wall of the first bracket 131. At this point, the user can easily pull out the aromatherapy stick 600. A new aromatherapy stick 600 or an aromatherapy stick 600 with added essential oil can be reinserted into the first bracket 131, and the rebound mechanism 610 can be locked by pressing again, so that only the aromatherapy outlet of the aromatherapy stick 600 is exposed on the surface of the first bracket 131.

[0130] In some embodiments, the pet air purifier further includes a magnetic element 630 and an iron element 640, one of which is mounted on a spring block 620 and configured to slide synchronously with the spring block 620, and the other of which is mounted on one end of the aromatherapy stick 600 facing the spring block 620.

[0131] The magnetic component 630 and the iron component 640 attract each other magnetically, forming a stable connection. This connection method not only ensures a stable connection between the aromatherapy stick 600 and the spring block 620 within the mounting cavity, but also prevents the aromatherapy stick 600 from shaking or falling off due to external forces. The connection method of the magnetic component 630 and the iron component 640 is highly flexible and can accommodate aromatherapy sticks 600 of different sizes, shapes, or weights. This adaptability allows the pet air purifier to easily accommodate a variety of aromatherapy stick 600 products on the market, improving device compatibility and user choice. The magnetic connection between the magnetic component 630 and the iron component 640 allows users to easily install or remove the aromatherapy stick 600 from the spring block 620 without the use of tools or complicated operations. This ability to quickly connect and disconnect greatly simplifies the installation and removal process of the aromatherapy stick 600, improving user convenience.

[0132] Optionally, the aroma diffuser stick 600 and the spring block 620 are each provided with a mounting slot, and the magnetic component 630 and the iron component 640 are respectively placed in the mounting slots of the aroma diffuser stick 600 and the spring block 620. The mounting slots ensure that the magnetic component 630 and the iron component 640 are accurately positioned during connection. This avoids the problem of loose connection or failure caused by inaccurate connection position, thereby enhancing the connection stability between the aroma diffuser stick 600 and the spring block 620. Moreover, the mounting slots make the structure of the aroma diffuser stick 600 and the spring block 620 more compact, which helps to reduce the overall size and weight of the pet air purifier.

[0133] In some embodiments, the pet air purifier further includes a plasma generator installed within the first chamber 110. The plasma generator uses a high-frequency electric field to ionize the gas, generating a large number of positive and negative ions and free radicals. These highly reactive particles can chemically react with pollutants in the air, thereby decomposing or transforming them into harmless substances. The positive and negative ions can also adsorb particulate matter in the air, causing it to settle, thus achieving the purpose of purifying the air.

[0134] Combination Figure 2-1 , Figure 6 and Figure 7 In some embodiments, the body 200 includes a cover 230, the inner side of which forms a second chamber 210. The pet air purifier also includes a light-emitting device 800 located at the junction of the head 100 and the body 200, and inside the cover 230. The light-emitting device 800 is configured to generate light toward the bottom of the body 200. Optionally, the cover 230 is transparent, which facilitates light transmission for user observation.

[0135] The body 200 is equipped with a cover 230, which allows users to easily observe the inside of the body 200, thereby monitoring the filtration status inside the body 200 in real time, and making it easier to determine whether cleaning is needed and to assess the effectiveness of the filter device 400.

[0136] The light emitted by the luminous device 800 increases the brightness inside the unit 200, allowing users to visually observe the cleanliness of the filter 400 inside the housing 230. This includes detecting the presence of pet hair on the filter 400 and the amount of pet hair filtered out. Furthermore, the light emitted by the luminous device 800 enhances the aesthetics of the pet air purifier, creating a pleasant atmosphere and attracting pets to stay longer.

[0137] In addition, the light-emitting device 800 is configured to generate light towards the bottom of the body 200, which can prevent the light from shining directly into the eyes of users or pets and causing adverse effects on their eyes. It can also make the light shining on the filter device 400 more uniform, making it easier to observe the attachment of debris (such as hair) on the filter device 400 and the presence of hair or dust floating in the second chamber 210.

[0138] In some embodiments, the light-emitting device 800 includes a light-emitting component 810, which is fixedly disposed at the bottom end of the head 100, and when the head 100 is connected to the body 200, the light-emitting component 810 is located at the junction of the head 100 and the body 200.

[0139] For example, the light-emitting component 810 is fixedly installed on the outer side of the bottom of the head unit 100. When the head unit 100 is connected to the body 200, the light-emitting component 810 is located inside the body 200. When the pet air purifier is in use, the light-emitting component 810 is hidden inside the body 200 to prevent the light-emitting component 810 from being damaged or covered with dust or hair and other debris.

[0140] Furthermore, the light-emitting device 800 also includes a light guide assembly 820, which is installed on the inner side of the top of the body 200. When the head 100 is connected to the body 200, the light guide assembly 820 is located on the light-emitting side of the light-emitting component 810. The light guide assembly 820 is configured to guide the light emitted by the light-emitting component 810 to propagate towards the bottom of the body 200.

[0141] The light guide component 820 can guide light to form a soft and uniform halo effect, making the overall appearance of the pet air purifier more elegant and sophisticated, and bringing users a more comfortable and pleasant user experience.

[0142] More importantly, the coordinated operation of the light guide component 820 and the light-emitting component 810 achieves precise control of light propagation through the principle of light reflection. The light guide component 820 ensures that light propagates in a predetermined direction, preventing direct light from shining into the eyes of users or pets, thereby reducing discomfort and eye damage. Simultaneously, the light guide component 820 also makes the light distribution on the filter device 400 more uniform, allowing users to more comprehensively observe the adhesion of debris at different heights on the outer surface of the filter device 400.

[0143] In some embodiments, the light-emitting component 810 includes a light strip 811, which is mounted on the bottom of the machine head 100 and extends circumferentially along the bottom of the machine head 100, and the light-emitting direction of the light strip 811 is radial along the machine head 100.

[0144] In this embodiment, the light strip 811 is installed at the bottom of the head unit 100 and extends circumferentially along the bottom of the head unit 100. This arrangement allows the light strip 811 to wrap around the bottom of the head unit 100, or, depending on actual needs, the length of the light strip 811 can be less than the circumference of the bottom of the head unit 100, for example, set to half the length of the bottom of the head unit 100. This satisfies basic lighting needs while allowing for flexible adjustment according to specific usage scenarios.

[0145] The light-emitting direction of the LED strip 811 is along the radial direction of the head 100, meaning that the light emitted by the LED strip 811 can propagate along the radial direction of the head 100. This allows the light to enter the light guide assembly 820 more effectively, thereby improving the utilization rate and propagation effect of the light. At the same time, the circumferential extension of the LED strip 811 around the head 100 increases the illumination range of the body 200, allowing users to clearly observe the interior of the body 200 from different angles.

[0146] When the head unit 100 is connected to the body 200, the light emitted by the light strip 811, guided by the light guide component 820, evenly illuminates the interior of the body 200, allowing users to visually observe the cleanliness of the filter device 400 and whether maintenance is required. Furthermore, the soft light emitted by the light strip 811 creates a warm and comfortable atmosphere, enhancing the user experience.

[0147] It's worth noting that the design of the 811 LED strip not only considers lighting effects but also aesthetics and durability. The 811 LED strip typically uses high-quality LED chips as its light-emitting element, offering advantages such as low energy consumption, long lifespan, and high brightness. Furthermore, the installation and removal process of the 811 LED strip is relatively simple and convenient, facilitating maintenance and replacement by users.

[0148] For example, the light strip 811 includes a circuit board, a plurality of LEDs, and a shielding member. The circuit board is a flexible circuit board and extends circumferentially along the head 100. The plurality of LEDs are mounted on the circuit board and arranged at intervals circumferentially along the head 100. The shielding member is connected to the circuit board and is located below the plurality of LEDs.

[0149] The circuit board features a flexible design, allowing it to extend flexibly along the circumference of the head unit 100 and adapt to complex installation environments. This not only improves the ease of installation of the LED strip 811 but also enables the LED strip 811 to better conform to the contours of the head unit 100, achieving a more uniform lighting effect.

[0150] Multiple LEDs are evenly mounted on the circuit board and arranged at intervals along the circumference of the head 100, ensuring that the LED strip 811 emits bright and uniform light to illuminate the interior of the body 200 for easy observation by the user. Furthermore, the number and arrangement of the LEDs can be flexibly adjusted according to actual needs to meet different lighting requirements.

[0151] The primary function of the shielding component is to prevent light from shining downwards from the LED beads, thus avoiding affecting the luminous effect. Simultaneously, the shielding component also protects the LED beads from impacts and damage from external objects. The thickness of the shielding component is between 0.8mm and 1.2mm; for example, a thickness of 1mm ensures both effectiveness and durability without adding excessive weight or bulk.

[0152] In some embodiments, the light-emitting component 810 further includes a lampshade 812, which is located at the bottom of the head 100 and covers the outside of the light strip 811. When the head 100 is connected to the body 200, the lampshade 812 is located between the light strip 811 and the light guide component 820.

[0153] The lampshade 812 can wrap around the bottom of the head unit 100, or be flexibly adjusted according to the length of the LED strip 811. The lampshade 812 protects the LED strip 811, effectively preventing it from being bumped or squeezed during connection or separation between the head unit 100 and the body 200, thus avoiding damage. Furthermore, even after the head unit 100 is separated from the body 200, the lampshade 812 continues to protect the LED strip 811 from external factors such as dust and moisture. This not only extends the lifespan of the LED strip 811 but also improves the overall reliability and durability of the pet air purifier.

[0154] Optionally, the light strip 811 and the head unit 100, and / or the lampshade 812 and the head unit 100, can be detachably connected. Specifically, the light strip 811 and the head unit 100, and / or the lampshade 812 and the head unit 100, can be connected using detachable methods such as snap-fit ​​connections, screw connections, or magnetic connections. This allows users to easily remove the light strip 811 and / or the lampshade 812 from the head unit 100 for cleaning, maintenance, or replacement as needed. The advantage of using a detachable connection method is that it improves the maintainability and expandability of the product. Users can maintain or replace the light strip 811 and the lampshade 812 without disassembling the entire head unit 100 or the pet air purifier. This not only saves users time and effort but also reduces maintenance costs.

[0155] Combination Figure 5-1 In some embodiments, the head unit 100 includes a housing 140 and a decorative ring 150. The decorative ring 150 is fixed to the bottom end of the housing 140. A fixing groove 152 is provided on the outer side of the decorative ring 150, extending circumferentially along the decorative ring 150. A light strip 811 is installed in the fixing groove 152, and a lampshade 812 is detachably connected to the decorative ring 150. For example, the fixing groove 152 is a semi-annular groove. Correspondingly, both the light strip 811 and the lampshade 812 are semi-annular. The light strip 811 is pressed into the fixing groove 152, and the lampshade 812 is detachably installed in the fixing groove 152.

[0156] By setting the fixing groove 152, the positioning of the light strip 811 and the lampshade 812 can be easily achieved, and the light strip 811 can be hidden within the fixing groove 152, avoiding light leakage and appearance interference, and also providing better protection for the light strip 811. In addition, the fixing groove 152 can also prevent the light strip 811 and the lampshade 812 from protruding from the decorative ring 150, which would affect the sealing and stability of the connection between the head 100 and the body 200.

[0157] Optionally, the opening of the mounting groove 152 faces the outside of the body 200. When the light strip 811 is installed in the mounting groove 152, water droplets from the outside or sliding down the surface of the head 100 are unlikely to enter the mounting groove 152, effectively avoiding the risk of water entering the mounting groove 152 and causing the light strip 811 to short circuit.

[0158] In some embodiments, the lampshade 812 snaps onto the decorative ring 150. This snap-fit ​​design allows the user to easily install the lampshade 812 onto the decorative ring 150 without the need for additional tools or fasteners such as screws, and also makes it convenient to remove the lampshade 812 for maintenance or replacement.

[0159] Combination Figure 9 and Figure 10 Optionally, the decorative ring 150 is provided with a plurality of first snap-fit ​​structures, which are arranged at intervals along the circumference of the decorative ring 150; the lampshade 812 is provided with a plurality of second snap-fit ​​structures, which are arranged along the extension direction of the lampshade 812 and are connected one-to-one with the first snap-fit ​​structures; wherein, one of the first snap-fit ​​structures and the second snap-fit ​​structures is a fixing buckle 813, and the other of the first snap-fit ​​structure and the second snap-fit ​​structure is a snap-fit ​​groove 151. In other words, a fixing buckle 813 is provided on the decorative ring 150, and a snap-fit ​​groove 151 is provided on the lampshade 812; or conversely, a snap-fit ​​groove 151 is provided on the decorative ring 150, and a fixing buckle 813 is provided on the lampshade 812, and the snap-fit ​​groove 151 and the fixing buckle 813 cooperate to achieve snap-fit ​​fixation between the lampshade 812 and the decorative ring 150.

[0160] To ensure the stability and ease of disassembly of the snap-fit ​​mechanism, the snap-fit ​​structure is typically designed to have a certain degree of elasticity. The retaining clip 813 can be designed with a flexible arm structure. When the retaining clip 813 is pressed down, the flexible arm deforms and snaps into the snap-fit ​​groove 151; when disassembly is required, simply press the retaining clip 813 gently and pull it outward.

[0161] For example, the lampshade 812 is provided with three fixing buckles 813, which are respectively located at both ends and the middle of the lampshade 812. Correspondingly, the decorative ring 150 is provided with three snap-fit ​​grooves 151, which are respectively located at both ends and the middle of the back of the fixing groove 152. The three fixing buckles 813 are connected to the three snap-fit ​​grooves 151 one by one.

[0162] For example, each of the elastic arm ends of the three retaining clips 813 is provided with a hook, wherein the hooks of the retaining clips 813 located at both ends of the lampshade 812 extend horizontally and face opposite directions, while the hook of the retaining clip 813 located in the middle extends vertically. Thus, when the lampshade 812 is connected to the decorative ring 150, the lampshade 812 can be well limited in different directions.

[0163] Optionally, a reflective layer is provided on the upper side of the lampshade 812. Exemplarily, the reflective layer includes a reflective coating or a reflective film. The reflective layer increases the reflectivity of the top of the lampshade 812, preventing light emitted from the light strip 811 from shining upwards through the top of the lampshade 812. This improves the overall brightness of the luminaire, ensures that light propagates in the intended direction, and enhances the targeting and effectiveness of the lighting. Preferably, the reflective layer is a diffuse reflection layer, avoiding problems such as excessive light concentration or glare. This not only improves the comfort and safety of the lighting but also facilitates the reflection of at least a portion of the light heading towards the top of the lampshade 812 to the guiding light assembly 820, improving light utilization efficiency.

[0164] Combination Figure 8 In some embodiments, the light guide assembly 820 includes a light guide post 821, which has a first sidewall 8211 and a second sidewall 8212. When the head 100 is connected to the body 200, the first sidewall 8211 contacts and engages with the light-emitting side of the light-emitting assembly 810, and the second sidewall 8212 is located on the side of the first sidewall 8211 away from the light-emitting assembly 810. The second sidewall 8212 gradually tilts away from the first sidewall 8211 from the top to the bottom.

[0165] In this embodiment, the first sidewall 8211 of the light guide post 821 contacts and cooperates with the light-emitting side of the light-emitting component 810. The light emitted by the light-emitting component 810 can pass through the first sidewall 8211 and enter the interior of the light guide post 821. After entering the interior of the light guide post 821, the light is reflected by the second sidewall 8212 and emitted from the bottom of the light guide post 821, and propagates towards the bottom of the body 200. The second sidewall 8212 gradually tilts away from the first sidewall 8211 from the top to the bottom, which can achieve a good light guiding effect and reduce light loss.

[0166] In some embodiments, the top of the cover 230 is provided with a bent portion 231 that bends toward the inside of the cover 230. The bent portion 231 has an inner groove 232 and a mating hole. The inner groove 232 is a groove structure formed by the side of the bent portion 231 near the center of the body 200, the side of the bent portion 231 away from the center of the body 200, and the top of the bent portion 231. The mating hole is located on the side of the inner groove 232 near the center of the body 200 and communicates with the inner groove 232.

[0167] The light guide assembly 820 includes a light guide bracket 822, which is an annular bracket. The light guide bracket 822 is installed in the inner groove 232, and the outer wall of the light guide bracket 822 is in contact with the inner wall of the inner groove 232. The light guide bracket 822 has a limiting part 8221 on the side near the center of the body 200. The upper side of the limiting part 8221 overlaps with the top surface of the docking hole, and the lower side of the limiting part 8221 overlaps with the top surface of the light guide post 821.

[0168] The first sidewall 8211 of the light guide post 821 is provided with a limiting protrusion 8213, which protrudes from the first sidewall 8211. The lower side of the limiting protrusion 8213 overlaps with the bottom surface of the docking hole for fixation. Furthermore, the limiting protrusion 8213 also overlaps with a support protrusion, the upper side of which is flush with the bottom surface of the docking hole. The portion of the first sidewall 8211 of the light guide post 821 located above the limiting protrusion 8213 is exposed at the docking hole position and contacts and engages with the light-emitting component 810. The portion of the first sidewall 8211 of the light guide post 821 located below the limiting protrusion 8213 contacts and engages with the inner wall of the bent portion 231. The side of the light guide post 821 facing away from the first sidewall 8211 contacts and engages with the inner wall of the light guide bracket 822.

[0169] In this embodiment, the lower side of the limiting portion 8221 of the light guide bracket 822 overlaps with the top surface of the light guide post 821, and the lower side of the light guide post 821 overlaps with the bottom surface of the docking hole, thereby limiting the light guide post 821 in the axial direction of the body 200 and preventing the light guide post 821 from moving along the axial direction of the body 200; the portion of the first sidewall 8211 of the light guide post 821 located below the limiting protrusion 8213 contacts and cooperates with the inner wall of the bending portion 231, and the side of the light guide post 821 away from the first sidewall 8211 contacts and cooperates with the inner wall of the light guide bracket 822, thereby limiting the light guide post 821 in the radial direction of the body 200 and preventing the light guide post 821 from moving in the radial direction of the body 200.

[0170] It is worth noting that the light guide bracket 822 and the bending part 231 can be fixedly connected by means such as snap-fit ​​or adhesive, or no additional connection structure can be provided. The light guide bracket 822 and the bending part and the light guide post 821 can be stably fixed inside the bending part by the cooperation of the light guide bracket 822, the bending part and the light guide post 821.

[0171] Optionally, multiple limiting protrusions 8213 are spaced apart along the extension direction of the light guide post 821. The inner wall of the mating hole overlaps with the multiple limiting protrusions 8213, or multiple mating holes are provided, and the inner walls of the multiple mating holes overlap with the multiple limiting protrusions 8213 in a one-to-one correspondence. For example, the light guide post 821 is provided with 3 limiting protrusions 8213, and 3 mating holes are provided on the inner side of the bent portion. The 3 limiting protrusions 8213 correspond one-to-one with the 3 mating holes, and the inner wall of the mating hole overlaps with the lower side of the corresponding limiting protrusion 8213. This can increase the stability of the installation of the light guide post 821 and prevent damage caused by excessive stress on a single limiting protrusion 8213.

[0172] Optionally, the light guide bracket 822 is provided with at least one of a first limiting groove and a first limiting rib, and the light guide post 821 is provided with a second limiting rib that mates with the first limiting groove and / or a second limiting groove that mates with the first limiting rib. In other words, the light guide bracket 822 is provided with a first limiting groove, the light guide post 821 is provided with a second limiting rib, and the second limiting rib is inserted into the first limiting groove; and / or, the light guide bracket 822 is provided with a first limiting rib, the light guide post 821 is provided with a second limiting groove, and the first limiting rib is inserted into the second limiting groove.

[0173] By cooperating with the first limiting groove and the second limiting rib and / or cooperating with the second limiting groove and the first limiting rib, the light guide post 821 can be limited in the 200-degree circumferential direction of the body, preventing the light guide post 821 from moving along the 200-degree circumferential direction of the body.

[0174] It is worth noting that the pet air purifier in this embodiment can also limit the light guide column 821 without the cooperation of the limiting groove and the limiting protrusion. The cooperation between the limiting protrusion 8213 and the inner wall of the docking hole, as well as the friction between the light guide column 821, the light guide bracket 822, and the bending part 231, can also prevent the light guide column 821 from moving circumferentially along the body 200. However, limiting the light guide column 821 by the cooperation of the limiting groove and the limiting protrusion can further improve stability.

[0175] In some embodiments, the top diameter of the decorative ring 150 is larger than the inner diameter of the bent portion 231, allowing the top of the decorative ring 150 to overlap with the top of the bent portion 231. The diameter of the middle portion of the decorative ring 150 is smaller than the top diameter of the decorative ring 150 but equal to the inner diameter of the top of the bent portion 231, allowing the bottom of the decorative ring 150 to be inserted into the bent portion 231. Preferably, when the bottom of the decorative ring 150 is inserted into the bent portion 231, the outer wall of the bottom of the decorative ring 150 contacts and engages with the inner wall of the bent portion 231. This allows the machine head 100 to be stably engaged with the machine body 200.

[0176] In some embodiments, the decorative ring 150, lampshade 812, and light guide post 821 are concentrically arranged. This concentric arrangement helps ensure precise alignment and a tight fit between the decorative ring 150, lampshade 812, and light guide post 821, improving the durability of the luminaire and reducing the risk of failure due to loose or misaligned components. Furthermore, it allows the light guide post 821 to more effectively guide light into the lampshade 812, achieving uniform light distribution and avoiding irregular light scattering within the luminaire, thereby improving the uniformity and comfort of the lighting.

[0177] In some embodiments, the housing 200 has a mounting port 260 communicating with the second chamber 210. The mounting port 260 is located at the top of the housing 200, and the cross-sectional dimension of the mounting port 260 is greater than or equal to the cross-sectional dimension of the filter device 400. The top of the housing 200 is detachably connected to the bottom of the head 100 via the mounting port 260, and the first chamber 110 and the second chamber 210 communicate with each other via the mounting port 260. The filter device 400 is detachably mounted in the second chamber 210 and is adapted to enter and exit the second chamber 210 through the mounting port 260.

[0178] Specifically, the filter device 400 is detachably installed in the second chamber 210 via, for example, a plug-in or threaded connection. When the cover 230 is provided with a bending portion 231, the inner side of the bending portion 231 forms the mounting port 260. The diameter of the mounting port 260 is greater than or equal to the diameter of the filter device 400, allowing the filter device 400 to enter and exit the second chamber 210 through the mounting port 260, facilitating the replacement or cleaning of the filter device 400. The bottom of the housing 140 of the head unit 100 is provided with an opening communicating with the first chamber 110. When the head unit 100 is plugged into the body 200, the bottom of the head unit 100 is inserted into the mounting port 260, thereby enabling communication between the first chamber 110 and the second chamber 210 through the mounting port 260.

[0179] In some embodiments, the filter device 400 includes a composite HEPA filter. A composite HEPA filter, or High-Efficiency Particulate Air Filter, is a device capable of filtering fine particulate matter from the air. Composite HEPA filters typically consist of multiple layers, each performing a different filtration function. Composite HEPA filters are highly efficient at filtering out fine particulate matter such as dust, pollen, bacteria, and viruses from the air, achieving an efficiency of over 99.7% for particles of 0.1 microns and 0.3 microns. The use of a composite HEPA filter in the pet air purifier's filter device 400 effectively filters out fine particulate matter from the air, improving indoor air quality and protecting the user's respiratory health.

[0180] Optionally, the filter device 400 also includes a mesh screen covering the outside of the composite HEPA filter. The airflow generated by the filter device 400 passes sequentially through the mesh screen and the composite HEPA filter. The mesh screen can initially filter out large particles in the air, such as dust and hair. If these large particles directly enter the composite HEPA filter, they may clog its tiny filter pores, reducing its filtration efficiency and service life. Therefore, the presence of the mesh screen plays a pre-filtration role, protecting the composite HEPA filter and extending its service life.

[0181] The pet air purifier in this embodiment uses a cylindrical filter device 400, which forms an air duct between itself and the cover 230, and also allows for easy observation of the pet hair attachment inside through the cover 230. Furthermore, the filter device 400 can be easily removed through the mounting port 260 for cleaning and maintenance, making it more convenient to use.

[0182] Combination Figure 1 In some embodiments, the body 200 further includes a base 240, which is located at the end of the cover 230 away from the head 100, is coaxial with the cover 230, and is detachably connected to the cover 230.

[0183] The base 240 serves as a support structure for the pet air purifier, improving its stability when placed upright. Furthermore, the base 240 and the cover 230 are detachably connected, allowing for easy removal and replacement or cleaning of the filter device 400 from the bottom of the cover 230 by separating the base 240 from the cover 230. In this embodiment, the detachable connection between the base 240 and the cover 230 includes, but is not limited to, plug-in, threaded, or hinged connections.

[0184] Optionally, the base 240 is disposed at the lower part of the cover 230 and is used to support the cover 230. Optionally, the base is also used to support the filter device 400.

[0185] Optionally, the base 240 is provided with a main air inlet 220. In some embodiments, the main air inlet 220 extends circumferentially around the axis of the base 240 and is located between the base 240 and the cover 230. To allow airflow to enter more smoothly through the main air inlet 220, the base 240 has a guiding surface 2411 for guiding airflow. The guiding surface 2411 tapers inward from top to bottom to prevent obstruction of airflow. Preferably, the guiding surface 2411 is an annular arc surface formed by rotating an arc around the axis of the base 240, and the annular arc surface protrudes outward. The arc shape is more conducive to airflow.

[0186] Furthermore, the main air inlet 220 is located between the lower edge of the cover 230 and the airflow-guiding surface 2411 of the base 240. The lower edge of the cover 230 is close to the ground, thus placing the main air inlet 220 at the bottom of the unit 200, making it easier to draw dust or pet hair and other impurities from the ground into the unit 200 for filtration. Optionally, the lower edge of the cover 230 extends outward from top to bottom, forming a flared opening together with the airflow-guiding surface 2411 of the base 240, which not only facilitates airflow but also helps reduce noise. Preferably, the lower edge of the cover 230 protrudes towards the airflow-guiding surface 2411, opposite the outwardly protruding arc surface of the airflow-guiding surface 2411, together forming a funnel-shaped flared opening, making it easy to draw in hair and dust from the ground near the pet air purifier.

[0187] Optionally, the vertical distance between the lower edge of the cover 230 and the ground is X1, and the horizontal distance between the lower edge of the cover 230 and the drainage surface 2411 of the base 240 is X2. The vertical distance X1 is the vertical distance from the lower edge to the ground, and the horizontal distance X2 is the minimum horizontal distance from the lower edge to the drainage surface 2411. Optionally, the vertical distance X1 is 20-50 mm, and the horizontal distance X2 is 20-60 mm. Preferably, the vertical distance X1 is 35 mm, and the horizontal distance X2 is 40 mm. Optionally, the ratio of the vertical distance X1 to the horizontal distance X2 is 0.5-2.2. Preferably, the ratio of the vertical distance X1 to the horizontal distance X2 is 0.8-1.

[0188] Optionally, the body 200 also includes a secondary air inlet 233, which is located on the cover 230 and communicates with the second chamber 210. Air entering the second chamber 210 through the secondary air inlet 233 can be filtered by the filter device 400. By providing the secondary air inlet 233 on the cover 230, air can be purified to remove odors and pet hair scattered in the air as pets climb up and down. The secondary air inlet 233 serves as an auxiliary air inlet, purifying the air while the pet air purifier is absorbing pet hair through the main air inlet 220. Preferably, the air intake area of ​​the main air inlet 220 is larger than that of the secondary air inlet 233. Of course, it is also feasible to only provide the main air inlet 220 without providing the secondary air inlet 233, which would increase the adsorption capacity of the main air inlet 220, allowing pet hair scattered at a greater distance on the ground around the pet air purifier to be adsorbed. However, to ensure air purification, in this embodiment, the air intake area of ​​the main air inlet 220 is 2-5 times that of the secondary air inlet 233. Furthermore, the secondary air inlets 233 are configured as a pair and symmetrically arranged on the cover 230.

[0189] In some embodiments, the base 240 includes a base for supporting the entire unit on the ground, and a drainage surface 2411 is the wall portion of the base over which airflow passes. Optionally, the drainage surface 2411 forms a sidewall of the base, with its lower end connected to the bottom surface of the base. The drainage surface 2411 is the outermost portion of the base, meaning that the minimum diameter of the drainage surface 2411 is greater than or equal to the diameter of any other portion of the base. Preferably, the filter device 400 is supported on the base.

[0190] Furthermore, the base 240 also includes a support portion and a connecting portion. The support portion supports the cover 230 and is detachably connected to the cover 230, while the connecting portion connects the base and the support portion. Optionally, the support portion has a contact surface that abuts against the lower edge of the cover 240, and the contacting surfaces are provided with a snap-fit ​​structure to achieve a detachable connection between the two. Multiple connecting portions can be provided to improve the connection strength between the support portion and the base, while also increasing the support strength for the cover 240.

[0191] Optionally, the main air inlet 220 is formed by a base and a support, and extends in a ring shape around the axis of the base 240. Connecting portions evenly divide the main air inlet 220 into several sub-air inlets. These sub-air inlets are arranged at intervals along the circumference of the base 240. Preferably, the multiple connecting portions are evenly spaced around the axis of the base 240, so that the multiple sub-air inlets are evenly spaced along the circumference of the base 240, i.e., the sub-air inlets are arranged at equal angles along the circumference of the base 240. The sub-air inlets increase the air intake volume and allow air to be drawn in from different directions, thereby improving air purification efficiency and increasing the cleaning range for impurities such as pet hair.

[0192] Optionally, the connecting portion extends radially outward and obliquely upward from the base to the supporting portion, creating a certain distance between the main air inlet 220 and the ground to avoid blockage, and forming a certain angle between the main air inlet 220 and the ground, which helps to increase the purification range. Preferably, the connecting portion and the supporting portion have an angle, further increasing the area of ​​the main air inlet 220.

[0193] The base 240 includes a base body 243 and a base cover 244, with the base cover 244 covering the base body 243. The filter device 400 is supported on the base cover 244. The base 240 is categorized from a functional perspective, comprising a base, a support, and a connecting portion. From a component composition perspective, the base 240 includes a base body 243 and a base cover 244. The base is formed by a portion of the base body 243; the support can be formed by a portion of the base body 243 or a portion of the base cover 244, or by both; similarly, the connecting portion can be formed by a portion of the base body 243 or a portion of the base cover 244, or by both.

[0194] Combination Figure 17 Optionally, the base 240 is equipped with a power cord hook 242. The power cord can be secured by the power cord hook 242, allowing the power cord to be close to the pet air purifier and avoiding messy wiring. After the power cord is secured, the device will not be affected by the swaying of the power cord during use, and it also makes the entire device look neater and more aesthetically pleasing.

[0195] Combination Figure 18 Optionally, the body 200 also includes a counterweight 241, which is fixedly connected to the base 240. Preferably, the counterweight 241 is disposed at the base of the base 240. The counterweight 241 can increase the weight of the pet air purifier to increase the stability and balance of the body 200. When fluid enters from the main air inlet, it will impact the base and cause it to shake. Therefore, the addition of the counterweight 241 makes the pet air purifier more stable, and prevents the pet air purifier from shaking when the pet jumps onto or off the support platform 130.

[0196] Optionally, there may be multiple counterweights 241, each of which is fixedly connected to the base body 243 of the base 240. Multiple counterweights 241 can provide greater weight and a more uniform weight distribution, which helps to further improve the stability of the equipment.

[0197] Optionally, multiple counterweights 241 are evenly arranged circumferentially around the axis of the machine body 200. Multiple counterweights 241 can provide greater weight and a more uniform weight distribution, which helps to further improve the stability of the equipment.

[0198] In some embodiments, the pet air purifier further includes a snap-fit ​​structure located at the connection point between the head unit 100 and the body 200, allowing the head unit 100 and the body 200 to engage with each other. This snap-fit ​​structure makes the assembly and disassembly of the head unit 100 and the body 200 easier and faster, effectively reducing the difficulty of using the pet air purifier.

[0199] Combination Figure 11 and Figure 12 In some embodiments, the snap-fit ​​structure includes a slot 250 and a snap-fit ​​button 160. The slot 250 is disposed in one of the head 100 and the body 200, and the snap-fit ​​button 160 is installed in the other of the head 100 and the body 200. The snap-fit ​​button 160 is adapted to snap-fit ​​with the slot 250.

[0200] For example, the snap-fit ​​button 160 is installed near the bottom of the head unit 100, and the slot 250 is located near the top of the body unit 200. When the head unit 100 is inserted into the body unit 200, the snap-fit ​​button 160 engages with the slot 250 to fix the head unit 100 and the body unit 200 relatively. When it is necessary to separate the head unit 100 and the body unit 200, the snap-fit ​​button 160 can be pressed to disengage it from the slot 250, thus unlocking the device.

[0201] Combination Figures 11 to 13 Optionally, the snap-fit ​​structure also includes a mounting base 170, which is fixedly connected to the head 100 or the body 200. The mounting base 170 has a pressing window 171, and the snap-fit ​​button 160 is connected to the mounting base 170. A portion of the snap-fit ​​button 160 passes through the pressing window 171 and is exposed on the head 100 or the body 200.

[0202] For example, the housing 140 of the head unit 100 includes an inner housing 141 and an outer housing 142. The inner side of the inner housing 141 forms a first chamber 110. A mounting base 170 is fixed between the inner housing 141 and the outer housing 142 by means of bolts or snap-fit. The mounting base 170 has a press window 171, and the outer housing 142 has an operating hole 144 opposite to the press window 171. A snap-fit ​​button 160 is connected to the mounting base 170 and has a pressing part 161 that passes through the press window 171 and the operating hole 144 and is exposed on the outside of the head unit 100. The user can unlock the snap-fit ​​button 160 by pressing the pressing part 161 inward. Various electrical components and other assembly structures are also disposed between the inner housing 141 and the outer housing 142.

[0203] In some embodiments, the snap-fit ​​structure further includes an elastic element 180, which is mounted on the mounting base 170 and connected to the snap-fit ​​button 160. The snap-fit ​​button 160 is configured to slide between a first position and a second position. In the first position, the snap-fit ​​button 160 is adapted to engage with a slot 250. In the second position, the snap-fit ​​button 160 disengages from the slot 250. The elastic element 180 is configured to provide an elastic restoring force to the snap-fit ​​button 160 as it slides from the first position to the second position.

[0204] For example, the elastic element 180 is a compression spring. When the user presses the latching button 160, causing the latching button 160 to slide toward the second position, the compression spring is compressed and deformed. After the user stops pressing the latching button 160, the compression spring supports the latching button 160 to return to its original position toward the first position. Of course, the compression spring can also be replaced by, for example, a leaf spring.

[0205] Combination Figure 14 and Figure 15 For example, the mounting base 170 is provided with a movable groove 172, which communicates with the pressing window 171. A compression spring is disposed in the movable groove 172. The snap-fit ​​button 160 is provided with a mounting part 162 connected to the pressing part 161. The mounting part 162 is slidably disposed in the movable groove 172. The compression spring is located in the movable groove 172, and one end of the compression spring abuts against the side wall of the movable groove 172 away from the pressing window 171, and the other end abuts against the mounting part 162.

[0206] In some embodiments, multiple snap-fit ​​buttons 160 and multiple card slots 250 are provided, and there is a one-to-one correspondence between the multiple snap-fit ​​buttons 160 and the multiple card slots 250. Through the cooperation of the multiple snap-fit ​​buttons 160 and the multiple card slots 250, the connection between the head 100 and the body 200 can be made more stable.

[0207] Optionally, two snap-fit ​​buttons 160 and two snap-fit ​​slots 250 are provided, with the two snap-fit ​​buttons 160 and the two snap-fit ​​slots 250 symmetrical about the center line of the head 100 or the body 200, respectively. When two snap-fit ​​buttons 160 and two snap-fit ​​slots 250 are provided, and the two snap-fit ​​buttons 160 and the two snap-fit ​​slots 250 are symmetrical about the center line of the head 100 or the body 200, not only is the stability of the connection ensured, but the force distribution is also optimized. The symmetrical layout allows the head 100 and the body 200 to be evenly stressed during connection, avoiding structural deformation or damage caused by uneven stress, thereby further enhancing the structural strength of the equipment. Furthermore, due to the one-to-one correspondence between the snap-fit ​​buttons 160 and the snap-fit ​​slots 250 and the symmetrical layout, users can more easily and quickly find the corresponding snap-fit ​​points during installation or disassembly, thus simplifying the operation process and improving work efficiency.

[0208] In some embodiments, the pet air purifier also includes a tilt switch for cutting off the power to the air supply device 300 when tilted. The tilt switch is installed on the head 100 or the body 200. If the pet air purifier tilts but the motor 310 continues to operate, it can easily affect the lifespan of the motor 310. Specifically, when the pet air purifier tilts, the shaft of the motor 310 is no longer vertically oriented, and the weight of the impeller 320 will be entirely on the shaft of the motor 310. Since the shaft and impeller 320 are rotating at high speed, the motor 310 is prone to bending and deformation. When the pet air purifier tilts, the tilt switch can control the power to the motor 310 of the air supply device 300 to prevent the motor 310 shaft from rotating at an angle, effectively ensuring the lifespan of the motor 310.

[0209] Optionally, the tilt switch is also used to cut off the power to the light-emitting device 800 when tilted, to further improve safety and extend the lifespan of the pet air purifier.

[0210] In some embodiments, the pet air purifier further includes a display device 900, which is mounted on the head unit 100 or the body 200 and is configured to display air quality information.

[0211] For example, the pet air purifier also includes a control board and air quality sensors (such as PM2.5 sensors, formaldehyde sensors, TVOC sensors, etc.), and the control board controls the display device 900 to display air quality information based on the detection signals of the air quality sensors.

[0212] For example, the air quality information mentioned above includes air quality levels. Specifically, based on the different levels of air quality, the control board determines the current air quality level based on the detection signal from the air quality sensor and controls the display device 900 to display numbers or graphics corresponding to the air quality level. For example, air quality is divided into three levels: poor, fair, and excellent. When the air quality is poor, the display device 900 displays a sad expression; when the air quality is fair, it displays a neutral expression; and when the air quality is excellent, it displays a happy expression. Of course, the above display format is only an example, and any display format that enables users to obtain air quality information is within the scope of protection of this embodiment.

[0213] In order to concentrate all electrical components on the machine head 100, the display device 900 is mounted on the machine head 100. For easy observation, the display device 900 is visible or protrudes from the operation hole 144 on the housing 142 for easy observation and operation.

[0214] In some embodiments, the pet air purifier further includes a walking device mounted on the bottom of the unit 200. The walking device allows the pet air purifier to be easily moved between different rooms or spaces, greatly improving ease of use. The walking device in this embodiment includes one-way wheels and / or omnidirectional wheels. Furthermore, the one-way wheels and omnidirectional wheels can also be configured as brake wheels, thereby facilitating the fixing of the pet air purifier's position.

[0215] In some embodiments, all electrical components of the pet air purifier are located in the unit head 100. This optimized space utilization, facilitates layout, installation, and maintenance, and improves safety while extending the lifespan of the electrical components. Furthermore, after separating the unit head 100 from the body 200, the body 200, which contains no electrical components, allows for easier cleaning of the filter device 400 or both the body 200 and the filter device 400 together.

[0216] The aforementioned electrical equipment includes not only the motor 310 and temperature control device 500, but also other electrical components such as light strip 811 and plasma generator.

[0217] Optionally, the head unit 100 is provided with a wiring port 190, which is electrically connected to the electrical components of the pet air purifier. For example, the wiring port 190 is located on the side wall of the head unit 100 and is suitable for connecting to the output terminal of the power adapter, so that the power adapter supplies power to the electrical components of the pet air purifier. When the pet air purifier is not in use or needs to be cleaned, disconnecting the power adapter from the wiring port 190 will completely cut off the power.

[0218] Furthermore, to ensure the electrical safety of the pet air purifier, it is designed to be in a power-off state and unable to operate after the head unit 100 is separated from the body 200. Optionally, the body 200 is equipped with a magnet, and the head unit 100 is equipped with a reed switch that cooperates with the magnet, so as to ensure that the pet air purifier is in a power-off state when the magnet and the reed switch are separated.

[0219] Specifically, a magnet is installed on the inner side of the body 200 that mates with the head unit, and a reed switch is installed inside the decorative ring 150 of the head unit 100. The reed switch is connected in series in the power supply circuit of the pet air purifier's electrical equipment. When the magnet and the reed switch are magnetically connected, the pet air purifier's electrical equipment is powered on, and the pet air purifier can be turned on and operate normally. When the magnet and the reed switch are magnetically disconnected, the pet air purifier's electrical equipment is powered off, and the pet air purifier cannot be turned on. This prevents the head unit from accidentally starting when the unit is tilted.

[0220] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0221] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
