Description

Technical Field

[0001] This invention relates to the field of pet supplies technology, and in particular to a drying device and method of use that can automatically adjust temperature and airflow. Background Technology

[0002] With the increasing popularity of pet ownership, the demand for pet care is growing. As a core grooming tool after bathing, the user experience and comfort of pet drying equipment have become key concerns for users. Currently, pet drying equipment on the market mainly works by delivering hot air into a sealed drying chamber to quickly dry pet fur.

[0003] Existing pet drying equipment generally suffers from technical problems such as overly concentrated airflow and poor pet comfort. Specifically, the air outlet design of existing equipment is relatively simple, typically using a direct opening or only a simple grille structure, lacking effective intervention in airflow pattern. When the fan is working, the airflow is ejected from the air outlet in the form of a high-speed jet, forming a "columnar" airflow concentrated in the central area of ​​the air outlet. This concentrated airflow has obvious characteristics: the airflow velocity distribution across the air outlet cross-section is extremely uneven, with the velocity in the central area being much higher than that in the peripheral areas, and most of the airflow energy concentrated in a relatively small cross-section.

[0004] When this concentrated airflow acts directly on a pet's skin, it creates a strong impact in certain areas. Pets are extremely sensitive to this sensation and may become agitated, resistant, or try to avoid the airflow during the drying process. In severe cases, pets may even develop a fear of the drying equipment, preventing them from completing the drying process properly.

[0005] In summary, how to solve the problems of excessively concentrated airflow, excessive airflow pressure on the pet's skin, and poor pet comfort in existing pet drying equipment has become a technical challenge that urgently needs to be addressed by those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to provide a drying device and method for automatically adjusting temperature and air volume. This invention sets multiple airflow dispersion components with dispersion holes on the uniform air branch pipe.

In case of any inconsistency, the meaning set forth in this specification or derived from the content described herein shall prevail. Furthermore, the terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit the scope of this application.

[0028] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0029] like Figure 1As shown, this invention provides a drying device and method for automatically adjusting temperature and airflow, including a drying chamber 1, an air supply module 2, a heating module 4, and a purification module 3; the drying chamber 1 is used to accommodate pets, and is provided with a return air inlet 13 and multiple air supply outlets 12; the air supply module 2 includes a fan 21, a return air duct 22, an air supply duct 23, and a uniform air distribution branch pipe 24, one end of the return air duct 22 is connected to the return air inlet 13, and the other end is connected to the air inlet of the fan 21; the purification module 3 has an air inlet connected to the air outlet of the fan 21. The air supply end is connected to purify and disinfect the airflow; the heating module 4 has its air inlet connected to the air outlet of the purification module 3 to heat the airflow, and its air outlet is connected to one end of the air supply duct 23; the air supply duct 23 is connected to the uniform air branch duct 24, which is equipped with multiple airflow dispersing components 26. The uniform air branch duct 24 is connected to the air supply outlet 12 through the airflow dispersing components 26. The airflow dispersing components 26 have dispersing holes to divide and diffuse the concentrated airflow into the air supply outlet 12 into a uniform and gentle airflow.

[0030] Specifically, the fan 21 is a low-noise centrifugal fan 21, with noise controlled below 50dB(A) to avoid excessive noise that may frighten the pet. The airflow dispersion component 26 installed on the uniform airflow branch pipe 24 divides and diffuses the concentrated airflow into a uniform and gentle airflow, significantly reducing the impact of the airflow on the pet and greatly improving the pet's comfort during the drying process.

[0031] like Figures 2-7 As shown in the figure, the arrows indicate the airflow direction during operation. The air supply duct 23 is connected to one end of two distribution ducts 25 via connectors 27. The end of the distribution duct 25 away from connectors 27 is closed. The distribution duct 25 extends vertically from the top to the bottom of the drying chamber 1. Each distribution duct 25 has multiple uniform airflow branch pipes 24 along its vertical extension direction. The uniform airflow branch pipes 24 are fixed to the drying chamber 1 perpendicular to the distribution duct 25. The end of the uniform airflow branch pipe 24 away from the distribution duct 25 is closed. The uniform airflow branch pipe 24 is connected to the air outlet 12 via an airflow diffuser 26, which divides and diffuses the concentrated airflow into a uniform and gentle airflow. In this embodiment, the connector preferably uses a standard tee joint made of ABS or 304 stainless steel to ensure connection sealing and structural strength.

[0032] Specifically, the drying chamber 1 is a sealed structure made of 304 stainless steel, which is corrosion-resistant, high-temperature resistant, and easy to clean. A drain hole is located at the bottom of the chamber, connected to an external drainage pipe to drain any dripping water from the pet. A transparent tempered glass observation window is located on the front wall of the chamber, allowing for easy observation of the pet's condition inside. An openable door 11 is located on one side of the chamber for easy entry and exit of the pet. The observation window uses a double-layered, hollow tempered glass structure, ensuring both high-temperature resistance and scratch resistance, while also providing heat insulation to prevent burns from excessively high external temperatures.

[0033] The purification module 3 includes a filter element. The purification module 3 also includes an ultraviolet germicidal lamp installed inside the drying chamber 1 or the return air duct 22. The ultraviolet germicidal lamp, installed inside the drying chamber 1 or the return air duct, is used to assist in sterilizing the air inside the chamber and the surface of the pet. The filter element is used to filter hair, dust, and other impurities from the air, preventing impurities from entering the air supply module 2 and affecting the stability and lifespan of the equipment.

[0034] Specifically, the ultraviolet lamp is a UV-C ultraviolet lamp with a main wavelength of 253.7nm and a power of 30W, used for auxiliary sterilization. The filter element is a HEPA high-efficiency filter with a filtration accuracy of H13 or higher, and a filtration efficiency of >99% for 0.3μm particles, used to filter impurities such as hair and dust.

[0035] The purification module 3 filters the circulating air and uses ultraviolet light to sterilize it, effectively removing pollutants such as hair and bacteria, providing a clean drying environment for pets.

[0036] like Figures 8-9 As shown, the heating module 4 includes multiple heating tubes 41, each independently configured and connected to an independent switching element 42 and indicator light 43. The switching element 42 controls the energization or de-energization of the corresponding heating tube 41; the indicator light 43 indicates the operating status of the corresponding heating tube 41. The switching element 42 is preferably a solid-state relay or an electromagnetic relay, which offers fast response and high control precision. The indicator light 43 is an LED indicator light, corresponding to the operating status of each different heating tube 41.

[0037] The drying unit also includes a temperature control module, which comprises a temperature sensor installed inside the drying chamber 1 and a temperature controller electrically connected to the temperature sensor and the heating module 4. The temperature controller adjusts the heating power of the heating module 4 based on the temperature detected by the temperature sensor inside the chamber. The temperature sensor is a PT100 platinum resistance sensor, located in the middle of the drying chamber 1, to monitor the temperature inside the chamber in real time. The temperature controller uses a microcontroller (MCU) with a built-in PID control algorithm, achieving a temperature control accuracy of ±1℃.

[0038] The drying unit also includes an alarm module electrically connected to the temperature controller. When the temperature sensor detects that the temperature inside the pet drying chamber exceeds a preset safety threshold, the alarm module issues an alarm signal, and the temperature controller stops the heating module 4. Specifically, the alarm module can be a flashing light and a buzzer, used to convey abnormal temperature information to staff and remind them to handle the situation promptly. The preset safety threshold can be set according to the pet type, typically 38℃. When the temperature exceeds the safety threshold, the buzzer emits a sound of 80dB or higher, the flashing light flashes at a frequency of 1-2Hz, and simultaneously the temperature controller cuts off the power to the heating module 4, while the air supply module 2 continues to operate to replenish the chamber with fresh air.

[0039] Through closed-loop control of temperature sensor and thermostat, the heating power of heating module 4 is dynamically adjusted to stabilize the temperature inside the enclosure within a safe and suitable range; in conjunction with alarm module, the safety of pets is further ensured.

[0040] The drying device also includes a wind speed control module, which includes a pet size detection unit, a wind speed sensor, and a wind speed controller. The pet size detection unit includes multiple infrared sensors spaced vertically to form an infrared sensor array. When a pet enters, multiple infrared sensors are triggered sequentially to obtain the pet's size information. The wind speed sensor is located at the air outlet 12 to detect the airflow speed. The wind speed controller is located inside the drying chamber 1 and is electrically connected to the infrared sensor, the wind speed sensor, and the fan 21. The wind speed controller adjusts the rotation speed of the fan 21 based on the pet size information obtained by the infrared sensor.

[0041] Preset body size classification standards: small dogs (body length < 50cm), medium dogs (50cm ≤ body length < 80cm), and large dogs (body length ≥ 80cm), with corresponding airflow volumes of 1.5m³ / h. 3 / min, 2.0m 3 / min, 2.5m 3 / min, the wind speed controller automatically adjusts the speed of the air supply fan 21 according to the pet's body length detected by the infrared sensor to achieve air volume adaptation.

[0042] The pet size detection unit employs an infrared sensor array, consisting of multiple infrared through-beam sensors spaced equidistantly along a vertical direction, with a sensor spacing of 3-5 cm. When a pet enters the drying chamber 1 at the entrance, its body sequentially blocks infrared sensors at different heights. The controller calculates the pet's length and height based on the number and position of the blocked sensors, combined with a preset mapping relationship. This detection method offers fast response, low cost, and meets the needs of pet size recognition.

[0043] The wind speed controller is a microcontroller with a built-in preset size-airflow mapping table. The wind speed controller adjusts the fan speed 21 via a PWM signal or a 0-10V analog signal, forming a closed-loop wind speed control to ensure that the deviation between the actual delivered airflow and the target airflow is ≤5%.

[0044] For larger pets, the airflow is increased to ensure drying efficiency; for smaller pets, the airflow is reduced to avoid excessive air pressure that could cause discomfort, achieving precise airflow matching and balancing drying efficiency with pet comfort. The fan speed control module automatically adjusts the speed of the fan based on the pet's size, ensuring precise matching of airflow to the pet's body shape and balancing drying efficiency and comfort for pets of different sizes.

[0045] The remote control module includes a communication unit and a remote terminal connected to the communication unit. The communication unit is located inside the drying chamber 1 and is electrically connected to the heating module 4, fan 21, wind speed sensor, and temperature sensor. It is used to collect operating status data of the drying device and send it to the remote terminal, as well as to receive control commands from the remote terminal. The remote terminal is a mobile terminal used to receive and display operating status data and send control commands to the communication unit. Operating status data includes chamber temperature, airflow speed, and equipment operating status. Control commands include heating temperature adjustment commands, airflow adjustment commands, and start / stop control commands. The communication unit uses a Wi-Fi or Bluetooth module, supporting IEEE 802.11b / g / n standards or Bluetooth 5.0 protocol, with a communication distance ≥10m. The remote terminal is a smartphone or computer with a dedicated application (APP) or mini-program installed. The user interface displays the temperature curve, wind speed value, and equipment operating status in real time and supports touch-screen parameter adjustment.

[0046] With the remote control module, users can view the equipment's operating status in real time and adjust parameters remotely, greatly improving ease of use.

[0047] This invention provides a method for using a drying device that can automatically adjust temperature and airflow, comprising the following steps: S1: Open the door 11 of the drying chamber 1, put the pet into the drying chamber 1 and then close the door 11. The user can start the device by adjusting the knob locally or by remote terminal. The preset heating temperature is 35℃. S2: The size information of the pet in the drying chamber 1 is obtained through the pet size detection unit, and the signal is transmitted to the wind speed controller. The wind speed controller automatically adjusts the speed of the fan 21 and outputs an appropriate air volume. S3: Start the air supply module 2, heating module 4 and purification module 3 to deliver a uniform and gentle airflow after heating into the drying chamber 1, and at the same time purify the air in the drying chamber 1. S4: Real-time detection of the temperature inside the drying chamber 1, and adjustment of the heating power of the heating module 4 according to the detected temperature to maintain the temperature inside the chamber within the preset range; specifically, when the temperature exceeds 38℃, the alarm module alarms, the temperature controller controls the heating tube 41 to stop heating, and the air blower 21 continues to blow air; when the temperature drops to 35℃, the heating tube 41 resumes operation to maintain a stable temperature inside the chamber. S5: After drying is complete, the user can turn off the equipment and open the door 11 to take out the pet via a remote terminal or local operation.

[0048] Therefore, the present invention provides a drying device and method for automatically adjusting temperature and air volume. In this invention, multiple airflow dispersion elements 26 with dispersion holes are set on the uniform air branch pipe 24. The uniform air branch pipe 24 is fitted with the air outlet 12 through the airflow dispersion elements 26. The concentrated airflow delivered by the air outlet pipe is transformed into a uniform and gentle airflow by the airflow dispersion elements 26 and sent into the chamber. This solves the problems of excessively concentrated airflow, excessive airflow pressure on the pet's skin, and poor pet comfort in existing pet drying equipment.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
