Description

Technical Field

[0001] This utility model relates to the field of pet cooling technology, and in particular to a multi-zone temperature control device for pets. Background Technology

[0002] As warm-blooded animals, dogs have significant limitations in their thermoregulation mechanisms. Sweat glands are only distributed on the paw pads and nose; core heat dissipation relies heavily on evaporation through respiration via the mouth and nose, as well as auxiliary heat dissipation through the skin of the neck, abdomen, and back. Studies show that the optimal temperature range for most common pet dog breeds is below 30°C. In hot summer environments, the external temperature can easily exceed a dog's physiological tolerance threshold, causing its body temperature to rise rapidly to dangerous levels. Clinical statistics show that heatstroke caused by high temperatures accounts for a significantly higher proportion of canine emergency room cases and may be accompanied by serious complications such as irreversible brain damage, multiple organ dysfunction, or coagulation abnormalities, endangering the dog's life.

[0003] Current methods for cooling down dogs mainly rely on passive measures or traditional equipment, which have significant drawbacks such as low efficiency, insufficient adaptability, and limited applicability to different scenarios. Among passive methods, while trimming fur can temporarily relieve the feeling of heat, it weakens the dog's skin's ability to protect against ultraviolet rays and increases the risk of sunburn; supplementing water only slows down the dehydration process and cannot directly affect the core thermoregulation mechanism. Regarding traditional equipment: Vertical fans (CN203239608U, CN203233853U, CN201836079U) suffer from dispersed airflow and high operating noise, making it difficult to accurately cover critical heat dissipation areas such as the large blood vessels in the neck and the thin skin on the abdomen of dogs; cooling pads (CN215123055U, CN209677056U) rely on static contact cooling, limiting their effective range and making them unsuitable for dynamic dog activity scenarios; while air conditioning technology (CN217284418U, CN309126946S, CN309046203S) can achieve overall environmental cooling, it suffers from high energy consumption and restricts the freedom of movement for dogs. Furthermore, existing technologies lack the ability to specifically adapt to the different heat tolerance thresholds of different dog breeds (such as the physiological differences between short-haired and long-haired dogs), and the dynamic control functions of the equipment are insufficient, making it difficult to achieve the goal of covering all breeds and all scenarios. Developing efficient and targeted active cooling technologies based on canine physiological characteristics has become a core need that urgently needs to be addressed in the field of pet health management.

[0004] Therefore, it is necessary to provide a multi-zone temperature control device for pets to solve the above-mentioned technical problems. Utility Model Content

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0031] Example 1

[0032] like Figure 1-3 As shown, the wearing body 1 is an open ring structure that can be worn around the neck of a pet, which can be a dog or an animal of similar size. The wearing body 1 includes multiple cooling modules. Each cooling module includes a cooling component 2 mounted on the wearing body 1, which is a cold source. The cooling component 2 includes a semiconductor cooling chip 21. A high thermal conductivity element 22 is mounted on the heat source side of the semiconductor cooling chip 21. A cooling fan 23 and a frame plate 24 are mounted on the side of the high thermal conductivity element 22 away from the semiconductor cooling chip 21. The cooling fan 23 extends outside the wearing body 1 and is located within the inner ring of the frame plate 24. The frame plate 24 is fixedly connected to and sealed with the wearing body 1. Multiple air intake holes 13 are provided on the wearing body 1 near the cooling fan 23, and the air intake holes 13 near each cooling fan 23 are distributed within the frame plate 24.

[0033] When the cooling unit 2 cools the corresponding area of ​​the pet's body through the airflow, at least one cooling module also includes a blower fan 5 installed in the first mounting cavity 3, an air inlet 4 opened on the first mounting cavity 3, and a directional air duct. The blower fan 5 is a silent centrifugal fan. The blower fan 5 blows the cold air generated by the cooling unit to the target area of ​​the pet's body through the directional air duct. The target area is mainly the head (mouth and nose), back and abdomen of the dog.

[0034] The directional air duct includes a head air duct 6, and the wearing body 1 has an oblique air outlet 7. The oblique air outlet 7 is connected to the head air duct 6, and the cold air in the head air duct 6 is blown out through the oblique air outlet 7.

[0035] In this embodiment, the cold end of the semiconductor cooling chip cools the ambient air. The fan 5 delivers the cooled air through the head air duct 6 to the angled air outlet 7 at a noise level of ≤25dB. The head air duct 6 can adopt a tapered streamlined design, and the angled air outlet 7 is arranged at a 45° angle towards the pet's head, forming a surrounding low-temperature airflow barrier covering the upper part of the head, muzzle, and nose area. The airflow temperature is 18-22℃, and the wind speed is 1.5-2.0m / s, to enhance the efficiency of respiration and evaporative heat dissipation.

[0036] The hot end of the semiconductor cooling chip is connected to the cooling fan via a highly thermally conductive aluminum alloy heat sink substrate or aluminum alloy heat sink fins. The cooling fan discharges excess heat through its heat dissipation vents using forced convection.

[0037] Example 2

[0038] like Figure 2-3 As shown, the directional air duct includes a back air duct 8. The wearing body 1 has multiple air outlets 9 on one side. The multiple air outlets 9 are arranged in a ring array and are all connected to the back air duct 8. The cool air in the back air duct 8 is blown out through the multiple air outlets 9. The air outlets 9 are directed towards the back of the dog, and the output airflow penetrates the fur layer on the back of the dog to cool down the back of the pet.

[0039] Example 4

[0040] The abdominal air duct 10 consists of multiple air outlets opened on the wearing body 1. The cold air generated by the cooling component is blown out through the air outlets. The cold air flow is output at a wind speed of 2-3m / s and penetrates the dog's abdominal hair layer with a thickness of ≥15mm.

[0041] Example 5

[0042] When the cooling component cools the corresponding area of ​​the pet's body through contact conduction, at least one cooling module also includes a heat-conducting layer 12 disposed in the second mounting cavity 11. The heat-conducting layer 12 extends beyond the wearing body 1, with one side of the heat-conducting layer 12 in contact with the cold surface of the cooling component 2 and the other side conforming to the pet's skin surface to conduct the cooling. The heat-conducting layer 12 is a flexible graphene composite material with a thermal conductivity ≥1500W / (m·K). The semiconductor cooling chip maintains the surface temperature of the heat-conducting layer within the range of 18-25℃, with a cooling rate ≥0.5℃ / s.

[0043] Example 6

[0044] The wearing body 1 has a notch, and fixing straps 15 are installed on both sides of the notch. Each end of the two fixing straps 15 is equipped with a buckle 16. The buckle is not limited to a snap buckle, magnetic buckle, snap buckle, or rotating buckle. The buckle 16 and the fixing straps 15 work together to securely fix the wearing body 1 to the pet's neck.

[0045] The main body of this device is made of aluminum alloy, with an inner layer covered with FDA-grade silicone with a thickness of 2mm, and the surface has an anti-slip texture.

[0046] The wearable body 1 also contains a battery 14, which supplies power to various electrical appliances and supports the Type-C fast charging protocol (PD 18W).

[0047] Each thermoelectric cooler is equipped with an NTC temperature sensor, which automatically cuts off the power when the detected temperature is greater than 50 ℃.

[0048] This device also includes an integrated touchscreen switch and a speed selection button. Its operation logic is as follows: a long press of the power button for ≥2 seconds triggers the power on / off cycle; a short press of the speed selection button sequentially switches between speeds: Level 1 (low power mode), Level 2 (standard mode), and Level 3 (enhanced cooling mode). All three speeds support intermittent pulse airflow (a 30-second working, 15-second pause cycle), and the maximum airflow speed is ≤4.5 m / s.

[0049] Level 1: 30W semiconductor cooling chip power, 1200 rpm fan speed, and ≥28 hours of battery life;

[0050] Second setting: 50W semiconductor cooling chip power, 1800 rpm fan speed, and ≥20 hours of battery life;

[0051] Three settings: 70W semiconductor cooling chip power, 2500 rpm fan speed, and ≥12 hours of battery life.

[0052] This device demonstrates its effectiveness in regulating the core temperature of a pet dog under various operating modes. Experimental data shows that, under an ambient air temperature of 32.4℃, when the initial core temperature of the pet dog was 39.7℃, different cooling modes exhibited significant performance differences. Specifically: the natural cooling mode (control group) showed the most limited temperature reduction, decreasing the core temperature by only 0.7℃ within a 15-minute observation period; single operating modes (cold air cooling or semiconductor cooling) exhibited similar cooling performance, with a temperature reduction of approximately 1.0℃, representing a 42.9% improvement over natural cooling; the synergistic operating mode (combined cold air and semiconductor cooling) demonstrated the best temperature control effect, achieving a 1.4℃ core temperature reduction within 15 minutes, reaching 200% of the cooling efficiency of the natural cooling mode, and a 40% improvement over the single operating mode. The above experimental data fully verifies the technical superiority of the synergistic cooling scheme proposed in this invention, which achieves a significant improvement in cooling efficiency through the synergistic effect of cold air convection and semiconductor heat conduction.
