Description

Technical Field

[0001] This utility model proposes an intelligent hair dryer with alternating air ducts, belonging to the field of hair styling appliances. Background Technology

[0002] Hair dryers are primarily used for basic drying. Most existing hair dryers provide a straight airflow, meaning the airflow exits vertically from the dryer and flows in a straight line. This can easily cause backflow during drying, hindering drying efficiency. Furthermore, the heating elements in most hair dryers have limited settings, such as low or high heat, resulting in a relatively limited airflow temperature that cannot be selectively adjusted based on the user's temperature tolerance, thus failing to provide a more comfortable temperature. Summary of the Invention

[0003] This invention provides an intelligent hair dryer with alternating air ducts to solve the problems existing in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an alternating air duct intelligent hair dryer, including a handle and a blower tube, the handle and the blower tube being fixedly connected, the blower tube having an air inlet end and an air outlet end, a first air outlet and a second air outlet being provided at the air outlet end of the blower tube, wherein both the first air outlet and the second air outlet are annular, and the first air outlet is located within the annulus of the second air outlet, the first air outlet is connected to a first air duct arranged along the axial direction of the blower tube, and the second air outlet is connected to the second air duct.

[0005] Preferably, a plurality of first spiral guide plates are provided on the inner side wall of the end of the first air duct near the first air outlet. The plurality of first spiral guide plates are arranged along the circumference of the first air duct so that the airflow is blown out in a spiral shape through the first air outlet under the action of the first spiral guide plates.

[0006] Preferably, the end of the first air duct is the first air inlet, and a first fan is provided in the first air duct along the direction away from the first air inlet. The first fan is used to form an airflow from the first air inlet to the first air outlet in the first air duct.

[0007] Preferably, a plurality of second spiral guide vanes are provided on the inner sidewall of the first air inlet, and the plurality of second spiral guide vanes are arranged along the circumference of the first air inlet so that the airflow forms a spiral airflow in the first air duct under the action of the second spiral guide vanes.

[0008] Preferably, the second air duct includes a first section fitted at the front end of the first air duct and a second section communicating with the first section. The second section is disposed inside the handle or between the handle and the air duct. A second fan is disposed in the second section, and the second fan is used to form an airflow from the second air inlet to the second air outlet in the second air duct.

[0009] Preferably, an adjustment plate is provided at the connection between the first segment and the second segment. The adjustment plate is used to adjust the size of the through hole at the connection between the first segment and the second segment in order to adjust the air flow rate entering the first segment per unit time.

[0010] Preferably, the adjusting plate is an arc-shaped plate with an adjusting handle on its outer side. An adjusting hole is opened on the air duct, and adjusting plate grooves are provided on the inner sidewalls of the air duct above and below the adjusting hole. The adjusting plate is set in the grooves, and the outer side of the adjusting plate contacts the inner sidewall of the air duct. The adjusting handle extends through the adjusting hole to the outer side of the air duct. The adjusting plate can slide along the grooves to block part of the through hole at the connection between the first and second sections, thereby changing the airflow through the through hole.

[0011] Preferably, at least one of the first and second air ducts is provided with a heating component, which is used to heat the airflow flowing through the duct.

[0012] Preferably, the heating component is disposed in the second air duct and is located close to the second air outlet.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model features a dual-air duct system, with a fan for both air intake and exhaust in each duct, allowing for individual control of the airflow in each duct.

[0015] 2. The present invention provides spiral air guide plates on the inner side walls of the first air inlet and the first air outlet, so that the air forms a spiral airflow in the first air inlet, which makes the airflow distribution uniform. Similarly, the spiral air guide plates at the first air outlet make the airflow blow out in a spiral state, which is not easy to generate backflow or vortex, resulting in greater airflow force and more uniform airflow.

[0016] 3. This utility model provides a heating component in at least one air duct, so that the two air ducts can provide multiple mixing modes, such as one air duct for cold air and one air duct for hot air, two air ducts for cold air, or two air ducts for hot air. At the same time, an adjustment plate is provided in the second air duct, so that the user can select the air flow rate of the cold air duct and the air flow rate of the hot air duct, so that the airflow temperature range after the two air ducts are mixed is large.

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] This telescopic device can be installed at the air outlet of a hair dryer to function as a hair dryer comb that can dry and shape hair.

[0026] like Figures 1-7 As shown, the alternating air duct intelligent hair dryer proposed in this embodiment includes a handle 10 and a blower 20. The handle 10 and the blower 20 are integrally molded and fixedly connected. The blower 20 and the handle 10 have a first housing and a second housing fixedly connected by bolts. A first air duct 100 and a second air duct 200 are formed inside the two housings. The air outlets of the first air duct 100 and the second air duct 200 are both set at one end of the blower 20. In this way, the two air ducts form two different airflows a and b at the air outlet.

[0027] In some embodiments, the air duct 20 has an air inlet end and an air outlet end. A first air outlet and a second air outlet are provided at the air outlet end of the air duct 20. The first air outlet 101 and the second air outlet 203 are both annular, and the first air outlet 101 is located inside the annulus of the second air outlet 203. The first air outlet 101 is connected to a first air duct 100 arranged along the axial direction of the air duct 20, and the second air outlet 203 is connected to the second air duct 200.

[0028] A plurality of first spiral guide plates 102 are provided on the inner wall of the first air duct 100 near the first air outlet 101. The plurality of first spiral guide plates 102 are evenly arranged along the circumference of the first air duct 100 so that the airflow is blown out of the first air outlet 101 in a spiral manner under the action of the first spiral guide plates 102. The first spiral guide plates 102 are integral with the inner wall of the air duct 20. Of course, a separate assembly design can also be adopted, such as setting slots in the inner wall of the air duct 20 or fixing it with bolts or other methods.

[0029] In some embodiments, the end of the first air duct 100 is a first air inlet 103, the first air inlet 103 is located at the air inlet end of the air duct 20, a first fan 104 is provided in the first air duct 100 along a direction away from the first air inlet 103, a first fan bracket is provided in the first air duct 100, and the first fan 104 is bolted to the first fan bracket. The first fan 104 is used to form an airflow from the first air inlet 103 toward the first air outlet 101 in the first air duct 100.

[0030] To enhance the spiral effect of the airflow at the first air outlet 101, a plurality of second spiral guide plates 105 are provided on the inner wall of the first air inlet 103. These second spiral guide plates 105 are arranged circumferentially along the first air inlet 103, so that the airflow forms a spiral airflow within the first air duct 100 under the action of the second spiral guide plates 105. The second spiral guide plates 105 here use the same mechanism and connection method as the aforementioned first guide plate 102, and will not be described in detail here.

[0031] In some embodiments, the second air duct 200 includes a first section 201 fitted at the front end of the first air duct 100 and a second section 202 communicating with the first section 201. The first section 201 is formed by the outer side wall of the front end of the first air duct 100 and the inner side wall of the front end of the air duct 20, forming a ring. The second section 202 is disposed inside the handle 10 or between the handle 10 and the air duct 20. A second fan bracket is disposed inside the second section 202. A second fan 204 is fixedly disposed on the second fan bracket by bolts. The second fan 204 is used to form an airflow from the second air inlet 206 to the second air outlet 203 within the second air duct 200.

[0032] It should be noted that, as Figure 1-3 As shown, when the second section 202 is set between the handle 10 and the air duct 20, a cavity is formed between the air duct 20 and the handle 10 to accommodate the second fan 204. This cavity is the second section 202. A second air inlet 206 is provided on one end face of the cavity. The side wall of the cavity is connected to the first section 201 through a through hole.

[0033] It should be noted that, as Figure 4-6As shown, when the second section 202 is set inside the handle 10, the second section 20 is formed by the handle housing. A second air inlet 206 is provided on the handle wall near the end of the handle 10. The second fan 204 is fixed inside the handle 10 by bolts or slots. It is connected to the first section 201 through a through hole at the connection between the handle 10 and the air duct 20.

[0034] In order to adjust the airflow within the second duct 200, an adjustment plate 30 is provided at the connection between the first section 201 and the second section 202. The adjustment plate 30 is an arc-shaped plate with an adjustment handle on its outer side. The adjustment plate is used to adjust the size of the through hole at the connection between the first section and the second section in order to adjust the airflow entering the first section per unit time.

[0035] It should also be noted that, as Figure 7 As shown, the adjusting plate 30 can also be configured as a cylindrical structure, which is fitted onto the inner wall of the air duct 20. The cylindrical structure is provided with an air hole 301. By rotating the adjusting plate 30, the size of the overlapping part between the air hole 301 and the through hole between the first section 201 and the second section 202 can be changed, thereby changing the air flow rate through the through hole into the first section 201.

[0036] It should be noted that an adjustment hole is provided on the air duct 20, and adjustment plate grooves are provided on the inner sidewalls of the air duct above and below the adjustment hole. The adjustment plate 30 is placed in the groove, and the outer side of the adjustment plate 30 contacts the inner sidewall of the air duct 20. This can prevent airflow from leaking through the gap between the adjustment plate 30 and the sidewall of the air duct 20. The adjustment handle 302 is set on the outer arc surface of the adjustment plate 30. The adjustment handle 302 extends through the adjustment hole 301 to the outside of the air duct. When it is necessary to adjust the airflow of the second air duct 200, the user can slide the adjustment handle 302 along the adjustment hole, thereby pushing the adjustment plate 30 to slide along the groove. This blocks part of the through hole at the connection between the first section 201 and the second section 202, thereby changing the airflow through the through hole.

[0037] In some embodiments, at least one of the first air duct 100 and the second air duct 200 is provided with a heating component 40. The heating component 40 includes a bracket and a heating wire, and operates on the same heating principle as a conventional hair dryer heating structure. The heating component 40 is used to heat the airflow flowing through its channel. For example, the heating component 40 is disposed in the second air duct 200 and is located near the second air outlet 203.

[0038] In addition, the hair dryer also has a control panel, to which the first fan 104, the second fan and the heating element are electrically connected, so that the start and stop of the first fan, the second fan and the heating element can be controlled by the control panel, and the control panel is controlled by buttons on the handle.

[0039] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
