Description

Technical Field

[0001] This utility model belongs to the field of pet supplies technology, specifically relating to a smart induction heating pad for pets. Background Technology

[0002] Traditional pet heating pads typically use manual switches and simple, fixed heating. However, manual operation is inconvenient and can easily lead to energy waste and safety hazards. When a pet steps onto the heating pad, the owner needs to manually turn it on; and when the pet leaves, it needs to be manually turned off. If the heating pad isn't turned on promptly, the pet may catch a chill, affecting its health. If the heating pad isn't turned off after the pet leaves, it not only wastes energy but can also overheat due to prolonged operation, or even cause a fire if forgotten to be turned off. Manual operation is even more unsuitable for elderly or mobility-impaired pet owners.

[0003] As for the fixed heating mode, although it provides a certain degree of temperature stability, it cannot automatically adjust the working status of the heating pad according to the actual use of the pet. It ignores the changes in the pet's actual temperature needs at different times and in different physical conditions. This may not only lead to unnecessary waste of energy, but may also increase the risk of overheating due to maintaining the same temperature for a long time. The safety hazards are particularly prominent when the pet is unattended.

[0004] Therefore, it is particularly important to develop a heating pad that can intelligently switch on and off and automatically adjust the heating status. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model proposes a smart induction heating pad for pets, which features automatic switching of the heating pad on and off by the pet, intelligent temperature control, and personalized settings, thereby improving the convenience, comfort, and safety of pet use.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] A smart pet heating pad includes a heating pad, a controller, and a power plug; the power plug is connected to the heating pad via the controller; the heating pad includes a heating layer, an insulation layer, a pressure sensing layer, a waterproof layer, and an outer cover arranged sequentially from the inside out; both the pressure sensing layer and the heating layer are electrically connected to the controller; the pressure sensing layer is a flexible pressure array sensor with a sufficiently large area to ensure comprehensive and accurate perception of the pet's weight distribution and position information when sitting or lying down.

[0008] The flexible pressure array sensor is composed of multiple rows of sensing plates (sensing points) connected end to end, and arranged on the upper surface of the insulation layer in E-shape, M-shape, square shape, spiral shape or irregular shape.

[0009] The heating pad body contains a temperature sensor electrically connected to the controller. The temperature sensor is an NTC temperature sensing element. It is used to monitor the temperature of the heating pad in real time and feed the data back to the temperature regulation unit in the controller.

[0010] The heating layer is a heating resistance wire, which is wrapped with a high-temperature resistant insulating material to ensure safe use.

[0011] The insulation layer is made of thickened cotton material to improve the insulation performance of the heating pad.

[0012] The waterproof layer is made of PVC material, which is designed to improve the waterproof performance of the heating pad and prevent potential problems such as internal circuit short circuits, component damage, and insulation layer failure. It has significant advantages and functions in terms of cleaning and maintenance, safety and durability, as well as adaptability and application range.

[0013] The outer cover is made of plush fabric, which enhances tactile comfort and facilitates cleaning and maintenance. Plush fabric not only provides excellent warmth but also offers a skin-friendly experience for pets, while also contributing to the heating pad's durability and safety.

[0014] The electrical connection wires between the outer casing and the controller are wrapped with wear-resistant and bite-resistant material to prevent pets from biting or damaging the electrical connection wires, thereby further enhancing durability and safety.

[0015] The controller includes a main control unit, and an electrothermal control unit, a pressure sensing unit, a temperature sensing unit, a control knob unit, a voltage stabilizing unit, and a display unit connected to the main control unit. Wherein:

[0016] The main control unit is used to process the input data, generate control signals or display signals, and output these signals to the corresponding functional units to realize the heating, shutdown, temperature adjustment and display functions of the electric heating pad, ensuring the normal operation of the entire heating pad system.

[0017] The electric heating control unit is used to adjust the power of the heating layer, control its on or off state, regulate the temperature, and has overheat protection and short circuit protection functions. It can automatically cut off the power in abnormal situations to ensure safety.

[0018] The pressure sensing unit (pressure sensing unit) provides power to the pressure sensor and transmits the data acquired by the pressure sensor to the main control unit for processing, in order to detect the gravity distribution of the pet on the heating plate.

[0019] The temperature sensing unit (temperature sensing unit) is used to provide power to the temperature sensor and transmit temperature data to the main control unit for processing.

[0020] The control button unit (control button unit) provides a human-machine interface, allowing users to adjust and set basic parameters such as the temperature and pressure of the heating pad.

[0021] The voltage regulator unit (voltage regulator) is used to provide a stable voltage to functional units such as the main control unit, pressure sensing unit, temperature sensing unit, and display unit, ensuring the stable operation of the entire controller.

[0022] The display interface unit (display unit) is used to receive and display data transmitted by the main control unit, such as the operating status of the heating pad, heating time, temperature setting, etc., so that users can observe and set them.

[0023] The controller has a built-in reservation function, providing multiple reservation time modes including 2 hours, 4 hours, 8 hours, 12 hours, 24 hours, and continuous operation. Users can easily set the working time of the heating pad through the operation panel according to their actual needs.

[0024] The controller has temperature control settings, providing 1 to 5 temperature levels, corresponding to an adjustable temperature range from 40℃ to 60℃, and achieves precise temperature control through an NTC temperature sensing element.

[0025] The controller supports two operating modes: sensing mode and normal mode. In sensing mode, the controller can automatically activate the heating function based on the pet's sitting or lying position; in normal mode, users can manually set the operating time and temperature settings. This flexibility and convenience meets diverse usage needs.

[0026] The controller also includes indicator lights and a buzzer. When the heating pad is in operation or a fault is detected, the controller will issue corresponding operation or alarm information to the user through the on / off state or color change of the indicator lights and the sound prompt of the buzzer.

[0027] Compared with the prior art, the beneficial effects of this utility model are reflected in:

[0028] 1. Automatic Start-up and Stop Function: The pet heating pad's built-in pressure sensor (pressure sensor plate) works in conjunction with the intelligent control system to accurately detect a pet's sitting or lying behavior. When a pet steps onto the heating pad, the system immediately responds and automatically activates the heating function to provide the pet with suitable warmth. When the pet leaves the heating pad, the system quickly and automatically shuts off the heating, avoiding unnecessary energy consumption and eliminating potential safety hazards caused by overheating or forgetting to turn it off. This innovative "pet sensor switch" design not only solves the shortcomings of traditional pet heating pads in terms of convenience, energy efficiency, and safety, but also brings convenience to both pets and owners, truly benefiting both.

[0029] 2. Intelligent Sensing of Pet Posture Changes. The sensor uses a flexible array of sensor sheets, with multi-point pressure distribution, overcoming the limitations of traditional four-point pressure distribution sensors that require a rigid board for support and are unsuitable for soft mats. The flexible array of sensor sheets fully covers the pet's sitting and lying areas, making the sensor array act like a fine sensing network, accurately capturing pressure changes in different postures such as standing, sitting, and lying down. Based on the changes in pressure distribution, the controller, according to a preset logic algorithm, can more rationally control the heating switch, further improving energy efficiency. Through the controller's intelligent processing, the heating temperature can be automatically adjusted to achieve the best heating effect, ensuring that the pet always enjoys a comfortable experience.

[0030] 3. Intelligent Temperature Control. The heating pad integrates a temperature sensor and combines it with gravity distribution data obtained from a pressure sensor to monitor and precisely adjust the temperature of the heating pad in real time, ensuring that your pet is always in the most suitable environment. At the same time, the heating temperature always fluctuates within a safe range, effectively preventing the risk of fire caused by overheating and achieving rational energy use.

[0031] 4. Personalized settings options. The controller offers multiple timer options and temperature adjustment levels, allowing pet owners to easily personalize settings via the panel buttons to meet their pets' specific needs and preferences. This enhances the flexibility, comfort, and versatility of use, providing pet owners with a more intelligent and convenient user experience.

[0032] 5. Environmentally friendly, safe, and long-lasting. Made of environmentally friendly, non-toxic, easy-to-clean, and waterproof PVC material, with a soft plush cover to ensure comfort and safety for pets. The electrical connection cord features a wear-resistant, bite-resistant, and easy-to-clean outer sheath, improving the heating pad's durability and ease of cleaning, and extending its lifespan.

[0033] 6. The controller's user interface is simple and compact, allowing pet owners to easily monitor the heating pad's working status and preset operations at any time. Attached Figure Description

[0040] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings and examples.

[0041] Example 1 (see Figures 1 to 5 )

[0042] A smart induction heating pad for pets includes a heating pad 1, a controller 2, and a power plug 3; the power plug 3 is connected to the heating pad 1 through the controller 2 to provide power to the heating pad and ensure that the heating pad can work normally.

[0043] Heating pad 1 includes, from the inside out, a heating layer 1-1, an insulation layer 1-2, a pressure sensor 1-3, a waterproof layer 1-4, and an outer jacket 1-5, wherein:

[0044] Heating layer 1-1 is made of heating resistance wire and covered with high-temperature resistant insulating material. It generates heat to provide a warm resting environment for pets. Heating layer 1-1 is electrically connected to controller 2.

[0045] Insulation layer 1-2, wrapped around the heating layer, effectively reduces heat loss, improves heating efficiency and the insulation performance of the heating pad, ensuring that pets can continuously feel warm.

[0046] Waterproof layers 1-4 are used to prevent moisture from seeping into the heating pad, protecting the circuits and components from moisture damage, and improving the product's durability and safety.

[0047] Outerwear 1-5 provides protection and an attractive appearance, while also increasing the pet's tactile comfort.

[0048] Pressure sensor 1-3 is electrically connected to controller 2 and is located between insulation layer 1-2 and waterproof layer 1-4. It is attached to the upper surface of insulation layer 1-2 and located below the area where the pet directly contacts it. It can comprehensively sense whether there is a pet on the pet mat, its weight and position, as well as the gravity changes generated when the pet sits or lies down, and transmit the sensing results to controller 2 for processing.

[0049] Pressure sensors 1-3 are flexible pressure array sensors, consisting of multiple pressure sensing plates arranged in a matrix, completely covering the insulation layer 2 area where the pet sits or lies down. This allows for comprehensive and detailed sensing of the pet's position and weight changes on the heating pad. Compared to conventional techniques that install pressure sensors around the perimeter or center of the heating pad, which require a hard plate underneath to detect the pet, reducing the pad's softness and the pet's comfort—especially for pets who like to curl up or frequently change sleeping positions, a hard plate can cause discomfort—the flexible pressure array sensors eliminate this problem. Because they use flexible materials, the sensors fit snugly against the heating pad surface without the need for a hard plate, providing a natural and comfortable environment for the pet. Furthermore, the comprehensive coverage and multi-point pressure sensing distribution of the flexible pressure sensor array create a fine sensing network covering the entire contact area, ensuring that all pressure changes are accurately captured and located. After receiving these detailed sensing signals, the controller analyzes and intelligently processes them to calculate the optimal heating strategy and sends instructions to the heater. During this process, the controller enables precise control of the heater, providing gentle heating to the pet's most sensitive areas that come into direct contact with it. It also intelligently distinguishes between the pet's standing and sitting / lying positions, automatically adjusting the heating temperature to suit its different activity patterns. For example, when the pet is lying down, the controller reduces the overall heating intensity to create a comfortable sleeping environment; when the pet is standing or active, it adjusts the heating temperature of the corresponding areas to promote blood circulation and enhance the pet's comfort. This precise adaptation to individual pet differences, behavioral habits, and different activity patterns effectively improves the pet's quality of life.

[0050] Controller 2 receives and processes signals from pressure sensors 1-3 and temperature sensors, adjusts the heating state and intensity of the heating pad according to a preset algorithm, automatically switches the heating pad on and off based on the presence of a pet, and dynamically adjusts the heating area based on the pet's position and weight distribution on the heating pad to achieve precise heating. It includes a main control unit, and connected to the main control unit are an electrothermal control unit, a pressure sensing unit, a temperature sensing unit, a control knob unit, a voltage stabilizing unit, and a display unit. Among them:

[0051] The main control unit, employing microprocessor technology, processes data transmitted from the pressure-sensitive unit. Through preset conditional logic, the microprocessor directs the operating mode of the heating layer, achieving intelligent temperature control and pet location sensing. This allows heating to automatically activate when the pet is sitting or lying down and automatically deactivate when the pet leaves, enhancing both convenience and safety for pets. The microprocessor coordinates the work of each component through pet presence recognition, temperature control, and energy-saving management algorithms, ensuring the heating pad responds quickly to changes, operates stably, and achieves high energy efficiency while maintaining pet comfort.

[0052] The display unit is a dual-LED digital display, connected to pins 11-15 of the main control unit. It receives and displays the data transmitted by the main control unit to show the current status of the heating pad, making it convenient for users to set the temperature, working time, etc.

[0053] The electric heating control unit mainly consists of components such as a silicon controlled rectifier (SCR) Q, a diode D3, and a resistor R7. Pin 5 (OUT) of the main control unit controls the conduction angle of the SCR Q through the positive terminal of diode D3 and resistor R7, thereby adjusting the power output and temperature of the heating layer, realizing functions such as opening and closing the heating layer, temperature regulation, and intelligent power-off protection.

[0054] The pressure sensing unit (pressure sensing unit) is connected to the output terminal of the voltage regulator circuit (VCC), pin 6 (YLD) of the main control unit, and the pressure sensor through R17. It is used to provide power to the pressure sensor and transmit the data acquired by the pressure sensor to the main control unit for processing, so as to detect the weight and position distribution information of the pet on the heating pad.

[0055] The temperature sensing unit (temperature sensing unit) is connected to the output terminal of the voltage regulator circuit (VCC), pin 8 (NTC) of the main control unit, and the temperature sensor through R18. It is used to provide power to the temperature sensor and transmit the temperature sensing data to the main control unit for processing.

[0056] The control button unit (control button unit) includes a power on / off button S1, a temperature increase button S2, a temperature decrease button S3, a time increase button S4, and a time decrease button S5. The control button unit's output terminal KEY is connected to pin 7 (KEY) of the control unit. The control unit monitors the voltage change at the KEY terminal and, combined with an internally preset threshold comparison mechanism and debouncing logic, accurately identifies which button emitted the input signal. Based on the user's operation, the control unit can execute corresponding functions or operations, such as adjusting settings, changing the temperature, or setting the working time.

[0057] The voltage regulator unit (voltage regulator unit) is mainly composed of a three-terminal voltage regulator U1, capacitor C4 and other components. It is used to provide a stable power supply to the main control unit, sensing unit and display unit to ensure the normal operation of the entire device.

[0058] Example 2 (see Figure 3 )

[0059] In this embodiment, the flexible pressure array sensor is composed of multiple rows of sensor sheets connected end to end, arranged in E-shape, M-shape, square shape, spiral shape, or irregular shape on the upper surface of the insulation layer 1-2. For heating pads that emphasize automatic switching by pets, the sensor points do not need to be too densely arranged. Therefore, this structure can effectively cover a large area with a small number of sensor sheets, thereby significantly reducing production costs.

[0060] Furthermore, compared to the rigidity and difficulty in rolling up and carrying of densely arranged sensor array heating pads, the flexible pressure array sensor of this embodiment has narrow and long connections between its sensor sheets, wide spacing, and sparse overall arrangement, resulting in excellent flexibility. This allows the heating pad to be easily rolled up or folded, effectively reducing its size, making it easy to carry and store, and lowering manufacturing costs.

[0061] Example 3 (see Figure 4 , Figure 5 )

[0062] In this embodiment, the heating pad 1 is equipped with temperature sensors 1-6 electrically connected to the controller 2. The temperature sensors are NTC temperature sensing elements used to monitor the temperature of the pet pad body in real time and send the obtained real-time temperature to pin 8 (NTC) of the main control unit. The main control unit compares the received real-time temperature with its internal preset temperature, and decides whether to activate the heating wire to generate heat based on the comparison result, thereby adjusting the temperature of the pet pad.

[0063] When a pet lies on the heating pad, a pressure sensor detects the pet's weight and sends a signal to pin 6 (YLD) of the main control unit. Pin 5 (OUT) of the main control unit then controls the heating element to heat the heating coil, raising the temperature of the pet pad. Simultaneously, the main control unit continuously monitors the pet's real-time temperature using a temperature sensor and compares it to the preset temperature. If the real-time temperature is lower than the preset temperature, the heating element will continue heating, stopping when the maximum preset temperature is reached.

[0064] Controller 2 features temperature control settings, offering 1 to 5 temperature adjustment levels, corresponding to temperatures adjustable from 40℃ to 60℃. Precise temperature control is achieved through an NTC temperature sensor. Users can set these settings via the operation panel (S1, S4, S5). The heating pad will automatically maintain the set temperature range, achieving intelligent temperature control.

[0065] Example 4 (see Figure 4 , Figure 5 )

[0066] In this embodiment, the controller 6 has a reservation function, providing multiple reservation time options including 2 hours, 4 hours, 8 hours, 12 hours, 24 hours, and continuous operation. Users can set the working time period of the heating pad through the operation panel (S1~S3) as needed to suit pets of different constitutions, sizes, and temperatures. It has both a basic constant temperature period and adjustable temperature, expanding its application range.

[0067] Example 5 (see Figure 2 )

[0068] In this embodiment, waterproof layers 1-4 are made of PVC material, which has excellent waterproof performance. This effectively prevents pet urine, saliva, and other liquids from penetrating into the internal circuitry and filling of the heating pad, ensuring the interior of the heating pad remains dry and undamaged. It avoids moisture buildup that could lead to short circuits, component damage, and other problems, extending the heating pad's lifespan and reducing odors caused by moisture, thus maintaining a fresh living environment for the pet. Furthermore, the smooth surface of PVC material makes it easy to wipe or rinse away stains and liquids, facilitating cleaning and maintenance. The waterproof layer effectively prevents the risk of electric shock caused by pets accidentally knocking over water cups or wetting the heating pad, improving the heating pad's safety. Additionally, PVC material is wear-resistant and scratch-resistant, able to withstand the pet's daily activities and is not easily damaged, thus enhancing the heating pad's durability.

[0069] Example 6 (see Example 6) Figure 1 )

[0070] In this embodiment, the electrical connection wire between the heating pad 1 and the controller 2 is wrapped with a wear-resistant and bite-resistant material, which can effectively prevent pets from chewing through the wire and avoid safety hazards such as short circuits and leakage. At the same time, it can resist the wear and tear caused by long-term trampling and dragging by pets, increasing the durability of the product, extending the service life of the heating pad, and bringing users a more reassuring and satisfactory user experience.

[0071] Example 7 (see Example 7) Figure 1 , Figure 2 )

[0072] In this embodiment, the heating pad cover 5 is made of plush fabric, which has the advantages of being comfortable and warm, skin-friendly and safe, beautiful and durable, easy to clean, and improving the pet's happiness. (1) Comfortable and warm: The plush fabric is soft and delicate, which can provide a comfortable touch for the pet, making the pet feel more at ease and relaxed when resting. In addition, it has a certain heat retention property, which can reduce heat loss and improve the heat retention effect of the heating pad, allowing the pet to feel more warmth in the cold season. (2) Skin-friendly and safe: The plush fabric is skin-friendly and will not cause irritation or allergies to the pet's skin, ensuring the pet's skin health. In addition, it has anti-static function, which can reduce the discomfort felt by the pet due to static electricity, and also helps to reduce the adsorption of dust and keep the heating pad clean. (3) Beautiful and durable: The plush fabric has rich colors and patterns, which can be matched according to the pet's preferences and home style, improving the aesthetics of the home. In addition, it has a certain wear resistance and tear resistance, which can withstand the pet's daily scratching and friction, extending the service life of the heating pad. (4) Improve the pet's happiness. Plush fabric heating pads can create a warm and comfortable resting environment, allowing pets to feel warmth and love during the cold season, which helps their healthy growth and reduces the risk of diseases caused by cold.

[0073] Example 8

[0074] In this embodiment, the heating pad offers two modes: a sensing mode and a normal mode. In sensing mode, heating automatically activates based on the pet's sitting or lying position, while in normal mode, heating is manually controlled. This design facilitates the modification of conventional heating pads. Furthermore, it makes the device more flexible, suitable for various occasions and needs, and can still function normally even if the sensor malfunctions unexpectedly.

[0075] Example 9 (see Example 9) Figure 5 )

[0076] In this embodiment, the controller is equipped with indicator lights and a buzzer. When the heating pad is in operation or a fault is detected, the indicator light will illuminate in the corresponding color or flash, and the buzzer will emit a warning sound to remind the user to pay attention and take appropriate measures.

[0077] When the heating pad is in operation, the controller receives corresponding signals (e.g., the detection voltage from the BT terminal of the heating control unit). Based on the preset program logic, the controller uses the drive circuit to control the indicator light to turn on or off or change its color, and to sound the buzzer. These signals include whether the heating pad is heating, the currently set temperature level, and whether the preset working time has been reached.

[0078] Similarly, when the controller detects a malfunction in the heating pad (such as overheating, short circuit, abnormal power supply, etc.), it will immediately trigger the alarm mechanism and send an alarm signal to the controller. Upon receiving these signals, the controller will immediately alert the user through indicator lights and a buzzer to remind the user to take appropriate measures and ensure safety during use.

[0079] Operation process

[0080] Step 1: Connect the power supply

[0081] Connect the heating pad's power cord correctly to a power outlet. The heating pad will automatically initialize (the first time it uses default values, and subsequent times it will automatically remember user settings), and the temperature sensor will start working, preparing for subsequent use.

[0082] Step 2: Set the heating temperature; intelligent temperature control.

[0083] 1. Users can directly set the heating temperature on the controller panel according to their needs. The temperature sensor continuously monitors the real-time temperature of the heating resistance wire.

[0084] 2. When the heating reaches the preset temperature, the heating pad will automatically stop heating to avoid overheating.

[0085] 3. To ensure stable temperature, the heating pad will periodically and automatically sense the temperature and restart heating when the temperature is lower than the preset value.

[0086] Step 3: Gravity sensor activation

[0087] The system defaults to sensor mode. When a pet sits on the heating pad, the pressure sensor detects the change in gravity on the pad and automatically activates the heating element to begin heating. Once the pet leaves, no gravity signal is transmitted to the controller, and the heating pad stops heating.

[0088] Intelligent switch (gravity sensor control): No manual operation is required. It automatically heats up and cuts off power by recognizing changes in gravity on the heating element.

[0089] Intelligent temperature control: Users can set the heating temperature according to their needs, and the heating pad will automatically maintain the temperature within the set range.
