Description

Technical Field

[0001] This utility model relates to the field of blower equipment technology, and in particular to a circular honeycomb heating blower device. Background Technology

[0002] Most hair dryers currently use heating wires for heating, and these heating wires are usually relatively large, taking up a significant amount of space in the hair dryer. When the heating wire heats the flowing air, a large amount of heated air dissipates from around the wire, resulting in low heating efficiency; and the outer casing near the heating wire can become too hot, causing burns to the touch.

[0003] To address this issue in the future, existing technologies also employ PTC honeycomb heating elements. A low-speed motor drives fan blades to generate airflow. This approach typically requires large ventilation openings in the PTC honeycomb heating element to deliver a sufficient volume of hot air. However, this method results in low heating efficiency for the PTC honeycomb heating element. Summary of the Invention

[0056] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the present invention.

[0057] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0058] See Figures 1 to 5This utility model provides a circular honeycomb heating and blowing device, including: a housing 10, a honeycomb ceramic heater 11, and a digital fan 50. The housing 10 is provided with a first air outlet 1021. The honeycomb ceramic heater 11 is installed in the housing 10 and located at the position of the first air outlet 1021. The digital fan 50 is disposed in the housing 10, and the air outlet duct of the digital fan 50 is connected to the honeycomb ceramic heater 11. The honeycomb ceramic heater 11 is used to heat the room temperature air output by the digital fan 50 and output it to the outside through the first air outlet 1021.

[0059] like Figures 1 to 5 As shown, the housing 10 may include a handle housing 101 and an air outlet housing 102. One end of the handle housing 101 is connected to the air outlet housing 102, and a first air outlet 1021 is provided on one side of the air outlet housing 102. The first air outlet 1021 may be a circular opening adapted to the honeycomb ceramic heater 11. Hot air heated by the honeycomb ceramic heater 11 can be output to the outside through the first air outlet 1021.

[0060] The honeycomb ceramic heater 11 is a high-efficiency heater with uniform heat distribution. Utilizing a metal alloy with excellent thermal conductivity, it ensures uniform surface temperature, eliminating hot and cold spots in the equipment. Furthermore, the honeycomb ceramic heater 11 is relatively small in size. The ambient temperature air output from the digital fan 50 is heated by the honeycomb ceramic heater 11 before being output, significantly reducing heat loss and improving heat utilization efficiency, thereby saving energy. Moreover, the relative heat insulation properties of the honeycomb ceramic heater 11 prevent the air outlet of the housing 10 from becoming excessively hot to the touch.

[0061] The honeycomb ceramic heater 11 can be circular. The room-temperature air output from the digital fan 50, after being heated, can be output through the circular air outlet, achieving a better airflow effect. In one embodiment of this invention, accessories such as a hair comb and nozzle can also be connected to the first air outlet 1021. The hair comb allows for hair styling. The flat nozzle concentrates the airflow, resulting in a stronger drying effect.

[0062] See Figures 2 to 5 The circular honeycomb heating and blowing device further includes an air guide duct 20, through which the honeycomb ceramic heater 11 is installed in the air outlet housing 102 to guide the room temperature air output by the digital fan 50 to the honeycomb ceramic heater 11.

[0063] like Figure 2 and Figure 5As shown, the honeycomb ceramic heater 11 is located on one side of the air outlet direction of the digital fan 50. The air duct 20 distributes the ambient temperature air output from the digital fan 50 relatively evenly before it reaches the honeycomb ceramic heater 11. This ensures that the ambient temperature air passes relatively evenly through the honeycomb ceramic heater 11, allowing all heating surfaces of the heater to heat the air, resulting in high heating efficiency and more uniform airflow.

[0064] See Figure 3 and Figure 4 The bottom of the air guide duct 20 is provided with a vent 201, which is connected to the air outlet duct of the digital fan 50. A second air outlet 202 is provided on one side of the air guide duct 20, corresponding to the first air outlet 1021, and the honeycomb ceramic heater 11 is installed at the second air outlet 202. The room temperature air output by the honeycomb ceramic heater 11 can be directly introduced into the air guide duct 20 through the vent 201. The interior of the air guide duct 20 has a ring-shaped structure, which can guide the room temperature air output by the digital fan 50 evenly before it is delivered from the second air outlet 202 to the air-receiving surface of the honeycomb ceramic heater 11; wherein the size of the air-receiving surface of the honeycomb ceramic heater 11 is adapted to the second air outlet 202. In this way, relatively uniform room temperature air can be output to the honeycomb ceramic heater 11 for heating, improving heating efficiency.

[0065] See Figures 2 to 5 The circular honeycomb heating and blowing device further includes: an inner shell 30, through which the digital fan 50 is disposed within the handle housing 101, and the end of the inner shell 30 is connected to the ventilation opening 201 at the bottom of the air guide duct 20. Figure 2 and Figure 5 As shown, the circular honeycomb heating and blowing device further includes an inner shell locking ring 40. The inner shell 30 includes a first inner shell 301 and a second inner shell 302. A locking ring mounting position 3011 is provided at the air outlet end of the first inner shell 301 and the second inner shell 302. The inner shell locking ring 40 is installed at the locking ring mounting position 3011 to lock the first inner shell 301 and the second inner shell 302. That is, the first inner shell 301 and the second inner shell 302 can be locked and fixed together by the inner shell locking ring 40. A receiving space is formed between the first inner shell 301 and the second inner shell 302, thereby allowing the digital fan 50 to be fixed inside the inner shell 30.

[0066] See Figures 3 to 5The circular honeycomb heating and blowing device further includes a control circuit board 60, which is installed inside the inner shell 30. The control circuit board 60 is electrically connected to the honeycomb ceramic heater 11 and the digital fan 50 to control the honeycomb ceramic heater 11 and the digital fan 50. The control circuit board 60 can output control signals to control the heating of the honeycomb ceramic heater 11 and simultaneously output control signals to control the rotation of the digital fan 50. The digital fan 50 is driven by a digital motor, enabling it to rotate at high speed, for example, a high-speed digital motor of 120,000 revolutions per minute. This provides sufficient airflow to the honeycomb ceramic heater 11.

[0067] See Figure 4 and Figure 5 The handle housing 101 is equipped with control buttons 601 and / or control switches 602, which are used to control the honeycomb ceramic heater 11 and the digital fan 50 through the control circuit. When using this circular honeycomb heating and blowing device, the control buttons 601 and / or control switches 602 can be controlled by hand force. Control buttons 601 can send control signals to the control circuit board 60, which in turn controls the honeycomb ceramic heater 11 and the digital fan 50. Control switches 602 can be used to switch the power supply to the control circuit board 60. For example, when not in use, the power supply can be turned off using the control switch 602 to ensure the electrical safety of the device.

[0068] See Figure 1 and Figure 5 The circular honeycomb heating and blowing device further includes: an air outlet cover 70, which has an air outlet gap and is located at the first air outlet 1021. Figure 1 and Figure 5 As shown, the air outlet plate is also a circular structure. The air outlet plate has air outlet slits, allowing the hot air heated by the honeycomb ceramic heater 11 to be output externally through the air outlet slits.

[0069] See Figure 4 and Figure 5 The circular honeycomb heating and blowing device also includes a rear cover 80. An installation port is provided on the other side of the air outlet housing 102, and the rear cover 80 is installed at the installation port via a snap-fit ​​connection. The air guide tube 20 can be inserted into the housing 10 of the air outlet housing 102 through the installation port. The snap-fit ​​method facilitates the installation and removal of the rear cover 80.

[0070] See Figure 1 and Figure 5The circular honeycomb heating and blowing device further includes a connector 90, which is connected to the other end of the handle housing 101. The connector 90 is used to introduce power supply to power the honeycomb ceramic heater 11 and the digital fan 50. The connector 90 can be connected to a socket via a connecting wire, thereby introducing power supply into the inner housing 30, which in turn powers the honeycomb ceramic heater 11, the digital fan 50, and the control circuit board 60.
