Description

Technical Field

[0001] The present invention relates to the field of handheld appliances, in particular to an automatic heat dissipation hair dryer. Background Art

[0002] Most of the hair dryers currently sold on the market have the motor assembly installed in the hair dryer body, which causes the following problems: (1) First, when the user uses the hair dryer to blow hair, the motor assembly drives the fan to rotate, thereby driving the air at the rear end of the hair dryer body to enter from the air inlet. The user's hair can easily be drawn into the fan from the air inlet of the hair dryer, causing a safety hazard; (2) Secondly, in order to prevent the high-temperature fluid blown out by the hair dryer from damaging the hair or burning the scalp, the user often needs to swing the hair dryer when using it to avoid directing the high-temperature fluid at one place for a long time to cause damage. This results in the use of existing hair dryers requiring a certain amount of physical strength and being inconvenient to use, especially for hairdressers, as blowing hair is a physically demanding task; (3) Furthermore, a large amount of heat is generated inside the hair dryer during use, and existing hair dryers basically do not have the function of heat dissipation, which shortens the service life of the hair dryer; (4) Finally, most existing hair dryers have the heating mechanism and motor assembly installed in the hair dryer body, which makes the hair dryer produced large in size and the center of gravity is at the top, which is inconvenient to grasp. Summary of the Invention

[0043] First embodiment:

[0044] like Figures 1 to 5 As shown, an automatic heat dissipation hair dryer includes a handle 1 and a body 2; a handle air duct extending along the length direction of the handle 1 is provided in the handle 1, and a body air duct extending along the length direction of the body 2 is provided in the body 2, and the handle air duct and the body air duct are connected; an air inlet connected to the handle air duct is provided at the bottom end of the handle 1, and an air outlet connected to the body air duct is provided at the front end of the body 2; the handle air duct includes a handle main air duct and a handle auxiliary air duct that are not connected to each other, and the body air duct includes a body main air duct and a body auxiliary air duct that are not connected to each other, the handle main air duct and the body main air duct are connected and can flow through high-temperature fluid; the handle auxiliary air duct and the body auxiliary air duct are connected and can flow through low-temperature fluid Fluid; the body 2 includes an outer tube 3, a boosting chamber 4 and a control chamber 5; the control chamber 5 includes a control chamber body 51 and a control chamber extension 52 extending outward from the control chamber body 51; the boosting chamber 4 has a boosting chamber hollow part 41 and a boosting chamber channel body 42 surrounding the boosting chamber hollow part 41; the control chamber extension 52 passes through the boosting chamber hollow part 41, and the boosting chamber 4 is sleeved in the outer tube 3, and the outer wall of the control chamber extension 52 and the inner wall of the boosting chamber channel body 42 form the second auxiliary air duct of the body, the boosting chamber channel body 42 forms the main air duct of the body, and the outer wall of the boosting chamber channel body 42 forms the first auxiliary air duct of the body.

[0045] A number of ribs 53 are provided on the outer wall of the control chamber extension 52, so that the low-temperature fluid can smoothly flow through the second auxiliary air duct of the body formed by the outer wall of the control chamber extension 52 and the inner wall of the boost chamber channel body 42. A number of through holes 54 are provided on the control chamber body 51 toward the control chamber extension 52, so that after the low-temperature fluid enters the control chamber 5 from the handle auxiliary air duct, the low-temperature fluid can flow out from these through holes 54 and enter the first auxiliary air duct of the body. The upper edge of the handle is matched with the outer tube 3, and an opening is provided on the side of the control chamber body 51 facing the handle auxiliary air duct. Preferably, the hair dryer control element 6 can be further provided in the body auxiliary air duct, and the low-temperature fluid can cool the hair dryer control element 6. The control chamber 5 is made of a material that can withstand 80°C or above. Preferably, the control chamber 5 is made of PPA plus 30% glass fiber.

[0046] When the hair dryer is running, the air at the bottom and / or side wall of the handle 1 enters from the air inlet at the bottom end of the handle 1 and is divided into two paths. One path enters the main air duct of the handle. This part of the air is heated by the heating wire into a high-temperature fluid. The high-temperature fluid enters the main air duct of the body, that is, the boost chamber channel body 42. Finally, the high-temperature fluid flows out from the main air duct outlet A of the body opposite to the boost chamber channel body 42.

[0047] Another stream of air entering from handle 1 enters the handle's auxiliary air duct. This portion of air is unheated and is therefore referred to as low-temperature fluid. The upper edge of handle 1 is sealed and mated with outer tube 3. The control chamber body 51 has an opening on the side facing the handle's auxiliary air duct. A portion of the low-temperature fluid from the handle's auxiliary air duct enters the control chamber body 51 through this opening. The blower control element 6 can be positioned within the control chamber body 51, and the low-temperature fluid flowing through it can promptly cool the blower control element 6. A through hole 54 is provided on the side of the control chamber body 51 facing the boost chamber 4. A part of the low-temperature fluid will flow out from the gap between the control chamber body 51 and the boost chamber channel body 42, and flow through the first auxiliary air duct of the body formed by the gap between the outer wall of the boost chamber channel body 42 and the inner wall of the outer tube 3, and finally flow out from the first auxiliary air duct outlet B of the body; another part of the low-temperature fluid will flow from the control chamber body 51 along the outer wall of the control chamber extension 52, and flow through the second auxiliary air duct of the body formed by the outer wall of the control chamber extension 52 and the inner wall of the boost chamber channel body 42, and finally flow out from the second auxiliary air duct outlet B of the body. The low-temperature fluid in the handle's auxiliary air duct can cool down the various components that make up the handle's main air duct, extending the service life of each component and preventing the handle from becoming hot during use. At the same time, the first and second auxiliary air ducts of the body are located on either side of the main air duct. The low-temperature fluid flowing through the first and second auxiliary air ducts can promptly cool down the various components of the hair dryer body, such as the components of the main air duct, the electronic components of the control system, the hair dryer housing, etc., extending the service life of the hair dryer while also preventing the hair dryer from becoming hot due to prolonged use. The high-temperature fluid flowing out of outlet A of the main air duct and the low-temperature fluid flowing out of outlet B of the first auxiliary air duct will meet and merge at the front end of the hair dryer body. Due to the superposition effect, the air volume is large and the temperature is mild, which has a good protective effect on the user's scalp and hair and can enhance the user experience.

The hair dryer also includes a negative pressure air duct, which runs through the front and rear ends of the body 2 and includes the control chamber hollow portion 55. The main body air duct, the auxiliary body air duct, and the negative pressure air duct are arranged concentrically and are not interconnected. The upper edge of the handle mates with the outer tube 3. The control chamber body 51 has an opening on the side facing the handle's auxiliary air duct. The control chamber 5 houses the blower control element 6, which is cooled by a low-temperature fluid. The control chamber 5 is made of a material that can withstand temperatures of 80°C or higher. Preferably, it is made of PPA with 30% glass fiber.

[0051] When the hair dryer is running, the air at the bottom and / or side wall of the handle 1 enters from the air inlet at the bottom end of the handle 1 and is divided into two paths. One path enters the main air duct of the handle. This part of the air is heated by the heating wire into a high-temperature fluid. The high-temperature fluid enters the main air duct of the body, that is, the boost chamber channel body 42. Finally, the high-temperature fluid flows out from the main air duct outlet A of the body opposite to the boost chamber channel body 42.

[0052] Another stream of air entering from the handle 1 enters the handle's auxiliary air duct. This portion of air is unheated and is therefore referred to as low-temperature fluid. The upper edge of the handle 1 is sealed and mated with the outer tube 3. The control chamber body 51 has an opening on the side facing the handle's auxiliary air duct. A portion of the low-temperature fluid from the handle's auxiliary air duct enters the control chamber body 51 through this opening. Preferably, a blower control element 6 can be further disposed within the control chamber body 51. The low-temperature fluid flowing through can promptly cool the blower control element 6.

The low-temperature fluid in the handle's auxiliary air duct can cool the various components that make up the handle's main air duct, extending the service life of each component and preventing the handle from becoming hot during use. At the same time, the first and second auxiliary air ducts of the body are located on either side of the main air duct. The low-temperature fluid flowing through the first and second auxiliary air ducts can promptly cool the various components within the hair dryer body, such as the components of the main air duct, the electronic components of the control system, the hair dryer housing, etc., extending the service life of the hair dryer while also preventing the hair dryer from becoming hot due to prolonged use. The high-temperature fluid flowing out of outlet A of the main air duct, the low-temperature fluid flowing out of outlet B of the first auxiliary air duct, and the air flowing out of outlet C of the negative pressure air duct will meet and merge at the front end of the hair dryer body.
