Description

Technical Field

[0001] This invention relates to the field of pet heaters, specifically a pet heater that can be used both at home and outdoors. Background Technology

[0002] With the continuous growth of the number of pets in households, various pet heating devices have gradually emerged on the market to meet the pets' need for warmth in low-temperature environments. These devices include pet electric heating pads, small fan heaters, and integrated pet constant temperature beds. These devices typically provide a warm environment for pets through electric heating elements or hot air circulation and are widely used in home living environments, especially suitable for the daily warmth of young pets, senior pets, or pets with weak constitutions.

[0003] However, the aforementioned pet heating devices are not adapted for use in pet cages or semi-enclosed environments. They are typically placed directly or simply hung, resulting in poor stability. These devices are prone to shifting or even tipping over due to pet activity, posing safety hazards. Furthermore, existing products mostly monitor temperature internally, failing to accurately reflect the ambient temperature of the pet's activity area. This can lead to overheating or insufficient warmth, affecting the pet's comfort and health. In addition, pets' living environments contain a lot of hair, dander, and dust. Existing heaters generally have ineffective air intake structures and internal dustproofing, allowing pollutants to easily enter the device and spread during heating. This not only affects the device's lifespan but may also impact the pet's respiratory health. Most products rely on a single mains power supply, making it difficult to meet the needs of outdoor travel, temporary placement, or power outages, thus limiting their application scenarios. Therefore, new technical solutions are needed to address these issues. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies, adapt to practical needs, and provide a pet heater suitable for both home and outdoor use. This addresses the problem that most current pet heaters are not designed for pet cages or semi-enclosed environments, typically using direct placement or simple hanging methods, resulting in poor device stability. These heaters are prone to displacement or even tipping over due to pet activity, posing safety hazards. Furthermore, existing products mostly monitor temperature internally, failing to accurately reflect the ambient temperature of the pet's actual activity area, potentially leading to overheating or insufficient warmth, affecting the pet's comfort and health. Moreover, pet living environments often contain a lot of hair, dander, and dust, and existing heaters generally have ineffective air intake structures and internal dust prevention, allowing pollutants to easily enter the device with the airflow and spread during heating, affecting not only the device's lifespan but also potentially impacting the pet's respiratory health. Finally, most products rely on a single mains power supply, making it difficult to meet the needs of outdoor travel, temporary placement, or power outages, thus limiting their application scenarios.

[0005] To achieve the objectives of this invention, the technical solution adopted is as follows: a pet heater suitable for both home and outdoor use is designed, comprising an upper shell and a lower shell, wherein the upper shell and the lower shell are interlocked to form an internal mounting chamber, wherein a heating and air supply component is provided inside the mounting chamber, wherein the heating and air supply component is connected to an intelligent temperature control component installed on the sides of the upper shell and the lower shell, and a cage fixing component is installed on the surface of the lower shell for fixing the heater to the pet cage.

[0006] Preferably, the heating and air supply assembly includes an ultra-quiet fan and an AC / DC universal PTC module, wherein the AC / DC universal PTC module is installed in the lower housing and is correspondingly arranged with the ultra-quiet fan installed in the upper housing.

[0007] Preferably, the outer surface of the lower shell is provided with an air outlet, and an aluminum heat insulation mesh is installed inside the air outlet.

[0008] Preferably, the upper shell surface is provided with an air inlet, and an air inlet cover is installed inside the air inlet. The air inlet cover is provided with a magnet that is magnetically and detachably connected to the magnet provided inside the upper shell by magnetic attraction.

[0009] Preferably, the air inlet cover has a slot inside, and a dustproof cotton is engaged inside the slot to filter pet hair, dander, and dust in the air entering the casing. At the same time, the dustproof cotton can be disassembled, replaced, or cleaned through the slot.

[0010] Preferably, the intelligent temperature control component includes a rotating temperature probe, which has a temperature sensor installed inside and a temperature probe connector installed at its end. The side of the temperature probe connector extends through a silicone rubber gasket into the mounting cavity. The silicone rubber gasket is used to create damping during the rotation of the probe, so that the rotating temperature probe can maintain its position after the angle is adjusted. The rotating temperature probe is made of food-grade 304 stainless steel to improve its anti-bite performance and ensure safety when in close contact with pets.

[0011] Preferably, the cage fixing assembly includes a positioning nut and a bolt assembly, wherein the bolt assembly passes through the cage body and is threadedly connected to the positioning nut installed in the lower shell for adjustment.

[0012] Preferably, a PCBA is installed between the upper and lower shells, and an AC / DC power socket is integrated on the surface of the PCBA.

[0013] Preferably, the lower shell surface has an opening, an LED light is installed on the inner side of the opening, and an LED lampshade is installed on the outer side.

[0014] Preferably, the upper shell surface has an opening, and a touch screen is installed inside the opening to display the working status and receive the target temperature parameter set by the user.

[0015] Preferably, the upper and lower shells are integrally molded from plastic material mixed with antibacterial masterbatch to inhibit the growth of bacteria on the surface of the shell.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention uses a rotatable temperature probe to collect real-time temperature data of the pet's activity area and combines this with intelligent temperature control to adjust the working state of the heating and air supply components, making the heating process more accurate and stable. Simultaneously, a magnetic air inlet cover and dustproof cotton structure are installed at the air inlet to filter hair, dander, and dust from the air, improving the internal environment of the device and enhancing its hygiene and reliability. Furthermore, by integrating an AC / DC power supply interface within the casing, the device can be used for both fixed home applications and outdoor or mobile scenarios, thus expanding the application range of the pet heater.

[0017] 2. This invention uses a cage fixing component in the lower shell to fix the heater to the outside of the pet cage. By rotating the temperature probe to extend the temperature sensor into the cage, the heating component is isolated from the pet. This achieves a safe heating mode with external fixing and internal detection, avoiding safety hazards caused by equipment tipping over, pet accidental contact, or chewing. The adjustable bolt assembly can flexibly adapt to cage meshes of different thicknesses and spacings, enabling quick and stable installation and solving the compatibility problem between the product and various pet cages.

[0018] 3. The rotating temperature probe of this invention adopts a food-grade stainless steel probe tube structure, which not only has sufficient mechanical strength to resist pet chewing and ensure the structural integrity and functionality of the probe tube, but its food-grade stainless steel structure also fundamentally guarantees the hygiene and health safety of parts that come into close contact with pets, and has good anti-chewing performance. At the same time, combined with the PID control algorithm, it can accurately adjust the temperature of the pet's actual activity area, improving the heating stability and comfort.

[0019] 4. This invention, by incorporating a magnetic air inlet cover and a replaceable dustproof cotton structure at the air inlet of the casing, effectively prevents pet hair, dander, dust, and other fine contaminants from being drawn into the machine, thereby maintaining clean air intake, preventing contaminants from accumulating on heat exchange components, ensuring stable heat dissipation efficiency, and fundamentally reducing operating odors caused by dust accumulation. It also greatly simplifies daily maintenance; users can easily remove the air inlet cover to periodically replace or clean the filter cotton, making maintenance extremely convenient. Furthermore, by ensuring internal cleanliness and good heat dissipation, it extends the service life of the motor and electronic components and improves the overall safety and reliability of the machine.

[0020] 5. The upper and lower shells of this invention are integrally molded from antibacterial materials, which inhibits the growth of bacteria on warm surfaces from the source. Combined with filter dustproof cotton, it effectively reduces microorganisms, dander, and dust that are spread with the warm air, providing a cleaner breathing environment for pets and improving the hygiene, ease of maintenance, and long-term reliability of the equipment.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments: Example 1: Home and outdoor dual-use pet heater, see [link / reference] Figures 1 to 5 It includes an upper shell 3 and a lower shell 13, which are interlocked to form an internal mounting chamber. The mounting chamber is equipped with a heating and air supply component, which is connected to an intelligent temperature control component installed on the side of the upper shell 3 and the lower shell 13. A cage fixing component is installed on the surface of the lower shell 13 to fix the heating unit to the pet cage.

[0023] For details, see Figure 1The heating and air supply assembly includes an ultra-quiet fan 6 and an AC / DC universal PTC module 7. The AC / DC universal PTC module 7 is installed inside the lower shell 13 and is correspondingly set to the ultra-quiet fan 6 installed inside the upper shell 3. The outer surface of the lower shell 13 is provided with an air outlet, and an aluminum heat insulation mesh 12 is installed inside the air outlet. The surface of the upper shell 3 is provided with an air inlet, and an air inlet cover 1 is installed inside the air inlet. The air inlet cover 1 is provided with a magnet, which is magnetically connected to the magnet set inside the upper shell 3. The air inlet cover 1 is provided with a slot, and a dustproof cotton 2 is engaged inside the slot to filter pet hair, dander and dust in the air entering the machine casing. At the same time, the dustproof cotton 2 can be disassembled, replaced or cleaned through the slot.

[0024] External air enters through the air inlet on the surface of the upper shell 3 and enters the installation chamber through the filtration of the air inlet cover 1 and the dustproof cotton 2 inside. The filtered air is heated by the PTC module under the drive of the ultra-quiet fan 6 to form an airflow. Then it is discharged through the air outlet on the surface of the lower shell 13 and is insulated by the aluminum heat insulation mesh 12 set in the air outlet.

[0025] For more details, see Figure 2 The intelligent temperature control component includes a rotating temperature probe 10, which houses a temperature sensor 11 and has a temperature probe connector 17 at its end. The temperature probe connector 17 extends into the mounting cavity through a silicone rubber gasket 9. The silicone rubber gasket 9 provides damping during probe rotation, allowing the rotating temperature probe 10 to maintain its position after angle adjustment. The rotating temperature probe 10 is made of food-grade 304 stainless steel to improve its anti-bite performance and ensure safety when in close contact with pets.

[0026] The heater is equipped with a rotating temperature probe 10. The temperature probe connector 17 at its end is angled under the damping effect of the silicone rubber gasket 9, allowing the temperature sensor 11 to extend into the pet cage to collect the ambient temperature of the pet's actual activity area in real time. The collected temperature signal is transmitted to the PCBA5. The PCBA5 calculates the heater power or fan speed of the heater based on the target temperature parameters received by the touch screen 4 using a PID control algorithm. When the measured temperature is close to the set value, the heating power is automatically reduced to prevent overheating. When the measured temperature is lower than the set value, the heating power is increased to quickly compensate for the heat. This process is carried out continuously and automatically, controlling the working status of the ultra-quiet fan 6 and the PTC module, thereby achieving the regulation of the temperature inside the cage.

[0027] Further, see Figure 3 The cage fixing assembly includes a positioning nut 15 and a bolt assembly 16. The bolt assembly 16 passes through the cage body 18 and is threadedly connected to the positioning nut 15 installed in the lower shell 13 for adjustment.

[0028] Because the heater is installed on the outside of the pet cage via the cage fixing assembly, and the temperature probe extends into the cage to measure the temperature, the heating and air supply assembly is always located outside the pet's activity area, thus isolating the heating component from the pet and achieving a safe heating mode with external fixing and internal detection. By setting a positioning nut 15 on the lower shell 13 and threading it with the bolt assembly 16, the heater can be installed on the surface of the cage body 18, preventing the equipment from shifting or tipping over during use and improving overall safety.

[0029] It is worth noting that, see Figure 4 and Figure 5 A PCBA5 is installed between the upper shell 3 and the lower shell 13. An AC / DC power socket is integrated on the surface of the PCBA5. An opening is provided on the surface of the lower shell 13. An LED light 8 is installed on the inner side of the opening, and an LED lamp cover 14 is installed on the outer side. An opening is provided on the surface of the upper shell 3. A touch screen 4 is installed inside the opening to display the working status and receive the target temperature parameter set by the user.

[0030] The PCBA5 is equipped with an integrated AC / DC power socket, which can select between AC power or DC power supply according to different usage scenarios, making the heater suitable for both fixed home use and outdoor or mobile scenarios.

[0031] It is worth emphasizing that, see Figure 1 The upper shell 3 and the lower shell 13 are integrally molded from plastic material mixed with antibacterial masterbatch to inhibit the growth of bacteria on the surface of the shell.

[0032] When using the dual-purpose indoor / outdoor pet heater, first thread the bolt assembly 16 through the mesh structure of the cage body 18 and connect it to the positioning nut 15 inside the lower shell 13. Tighten and adjust to fix the heater to the outside of the pet cage. Depending on the usage scenario, connect the mains power or DC power to the AC / DC power socket on the PCBA5. After the device is powered on, it enters standby mode, and the LED light 8 illuminates to indicate that the device is powered on. The user sets the target heating temperature through the touch screen 4 on the surface of the upper shell 3, and the set parameters are transmitted to the PCBA5 for storage. The angle of the rotating temperature probe 10 is adjusted by controlling and adjusting it so that the rotating temperature probe 10 and temperature sensor 11 extend into the pet cage. Since the heater is installed on the outside of the pet cage via bolt assembly 16 and positioning nut 15, and the rotating temperature probe 10 extends into the cage to measure the temperature, the heating and air supply assembly is always located outside the pet's activity area, thus isolating the heating component from the pet and achieving a safe heating mode of fixed outside the cage and detection inside the cage. The rotating temperature probe 10 maintains a stable position under the damping action of the silicone rubber gasket 9, ensuring the temperature of the pet's activity area. The ambient temperature is monitored in real time. PCBA5 controls the ultra-quiet fan 6 to start and drives the AC / DC universal PTC module 7 to heat the incoming air based on the comparison between the real-time temperature collected by temperature sensor 11 and the set target temperature. After being protected by aluminum heat insulation mesh 12, the warm air is delivered from the air outlet. During the operation of the equipment, temperature sensor 11 continuously collects the internal temperature of the cage. PCBA5 dynamically adjusts the fan speed and the working status of the PTC module according to the temperature changes to keep the internal temperature of the cage stable within the set range. Specifically, it calculates based on PID control algorithm to dynamically and smoothly adjust the heater power or fan speed of the heater. When the measured temperature is close to the set value, the heating power is automatically reduced to prevent overheating. When the measured temperature is lower than the set value, the heating power is increased to quickly compensate for the heat. This process is continuously and automatically controlled to control the working status of ultra-quiet fan 6 and PTC module. After a period of use, the air inlet cover 1 can be removed by magnetic attraction to clean or replace the dustproof cotton 2 to ensure unobstructed air intake and long-term stable operation of the equipment.

[0033] In addition, all components designed in this invention are general standard parts or components known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this invention does not involve improvements to the internal structure and method.
