Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hair drying devices, in particular to a high-efficiency air outlet nozzle and a straightening air comb. BACKGROUND

[0002] A straightening air comb with transverse air outlet is disclosed in Chinese Patent No. CN119924631A, which comprises a shell assembly with an air outlet gap, an electric fan and a heating component are built-in at the handle of the shell assembly, a flow guide component is movably arranged in the shell assembly, and a flow guide structure is arranged on the flow guide component and can be moved to one side of the air outlet gap and be in staggered connection with the air outlet gap, the flow guide structure comprises a plurality of groups of air inlet gaps and air outlet gaps arranged on the flow guide component, when the electric fan works, the air flow is output from the handle to the head of the shell assembly, then passes through the flow guide structure, and finally is output outward from the air outlet gap, since the flow guide structure is in staggered connection with the air outlet gap, the direction of the air flow finally blown out by the straightening air comb is transversely inclined.

[0003] In the above-mentioned straightening air comb, only a small part of the air flow in the shell passes through the flow guide component and directly blows into the air inlet gap, and the remaining air flow directly impacts the area of the flow guide component where the flow guide structure is not arranged and is blocked, resulting in low flow rate areas on both sides of the air inlet gap, and these air flows can only slowly flow into the air inlet gap with the subsequent air flow directly blowing out of the air outlet gap, which slows down the flow rate of the air flow and reduces the wind power, therefore, the air outlet gap structure of the existing straightening air comb has large air resistance, the efficiency of converting the output power of the electric fan into effective wind power is low, and the straightening air comb has the defects of high energy consumption and low efficiency. SUMMARY

[0004] In view of the above-mentioned defects of large internal air resistance, high energy consumption and low efficiency of the existing straightening air comb, the first object of the present application is to provide an air outlet nozzle capable of efficiently outputting wind power.

[0005] To solve the above-mentioned technical problems, the present application solves the problems by the following technical solutions: A high-efficiency air outlet nozzle, comprising a shell and an air outlet assembly with a plurality of air outlet gaps arranged at intervals on the shell, and a flow guide assembly arranged at intervals on the air outlet assembly and guiding the air flow in the shell to the air outlet gaps, the flow guide assembly is formed with a flow guide surface in abutment with the adjacent air outlet gap and extending in expansion relative to the air outlet gap.

[0006] Using the above solution, when the airflow blows towards the air outlet gap, the airflow that does not directly blow towards the air outlet gap will first impact the guide surface and change its flow direction along the guide surface. Finally, it will converge with the airflow that directly blows towards the air outlet gap and surge towards the air outlet gap. Compared with the existing technology, the guide component in this solution can effectively guide the airflow using the guide surface, reduce the velocity difference near the air outlet gap, and make the airflow blowing process smoother, thereby reducing wind resistance and improving the air outlet efficiency of the hair straightener.

[0007] Preferably, the diversion assembly includes diversion blocks located between two adjacent air outlet gaps and distributed along the length of the air outlet gaps. The cross-section of the diversion block is wedge-shaped and the tip faces away from the air outlet gap. The two sides of the tip of the diversion block form diversion surfaces that respectively connect with the two adjacent air outlet gaps.

[0008] Preferably, the airflow guiding assembly includes airflow guiding wings located at the first and last ends of all airflow gaps in the arrangement, on the side away from the airflow guiding block. The airflow guiding wings extend obliquely towards the side away from the airflow guiding block, and the side of the airflow guiding wings facing the airflow guiding block forms an airflow guiding surface.

[0009] Using the above scheme, the tip of the diversion block can divert the airflow to the diversion surfaces on both sides, reducing the stagnation caused by the direct impact of the airflow. The diversion surfaces on both sides of each air outlet gap are distributed in the shape of a trumpet, with the diameter becoming smaller closer to the air outlet gap, similar to the structure of a Venturi tube, which accelerates the airflow and can increase the wind power to a certain extent without changing the power of the electric fan.

[0010] Preferably, the air outlet assembly includes a hood with a plurality of air outlets spaced apart and connected to the air outlet gap. A guide component is movably disposed between the hood and the diversion component, which drives the airflow to be blown out laterally from one side of the air outlet. The air outlet gap is opened on the guide component, and the diversion component is fixedly protruding on the guide component.

[0011] Using the above solution, when people are combing their hair, the straightening comb will bend the hair to be parallel to the air outlet. The straightening comb in this solution can blow air in a horizontal tilting manner, and the airflow will blow along the length of the hair, which can dry the hair faster and more thoroughly. In addition, in this solution, people can adjust the airflow guide to a preset position according to the direction of combing their hair, so that the direction of airflow is in line with the direction in which the hair is bent when combing.

[0012] Preferably, a diversion component is fixedly installed inside the housing to evenly distribute the airflow to various parts of the air outlet assembly. The diversion component includes a partition plate vertically arranged inside the housing and diversion plates horizontally protruding on both sides of the partition plate and distributed at intervals along the vertical direction. One side of the diversion plate is connected to the air outlet gap, and the other side is bent downward.

[0013] By adopting the above scheme, the flow distribution component in this scheme can evenly distribute the airflow output by the electric fan to various parts of the flow guide component, thereby ensuring uniform airflow at each air outlet and at each part of the air outlet.

[0014] Preferably, the flow guiding component has a mating groove that engages with the flow splitter plate, and the flow guiding component slides laterally with the flow splitter component through the mating groove.

[0015] In the prior art, the air shroud and the air guide component are fitted together to form an air outlet assembly. The air outlet assembly is pressed onto the splitter plate during the assembly of the outer shell. However, there is no interactive structure between the air guide components. Therefore, the air guide components can move freely relative to the splitter plate when the outer shell is not installed, making pre-assembly difficult. In this solution, the air guide component can be snapped onto the splitter plate through the mating joint. The mating groove provides a pre-positioning effect between the air guide component and the splitter component, which facilitates the assembly of the outer shell. After the outer shell is assembled, the air guide component can also slide laterally along the splitter component with the help of the mating groove to achieve the effect of switching the blowing direction.

[0016] Preferably, the air outlet gap includes a plurality of air guide grooves formed by the recess of the air guide component facing the air outlet, and an air inlet groove that is opened through the middle of the air guide groove and is narrower than the air guide groove. The air inlet groove slides back and forth between the two sides of the air outlet with the air guide component and is misaligned with the air outlet through the air guide groove.

[0017] Using the above solution, this solution limits the lateral tilting air outlet mode of the air outlet component. When the air guide component moves to one side of the air inlet slot, the air guide slot will connect with the gap between the air outlet and the air inlet, while the other part of the air guide slot is covered by the wind cover to prevent the airflow from flowing out. At this time, after the airflow enters the air inlet gap, it will turn into lateral flow in the air outlet gap, and then be blown out laterally at an angle from the air outlet.

[0018] Preferably, a limiting structure is provided between the air guide component and the housing to prevent the air guide component from moving after the air inlet slot is connected to the air outlet through the air guide slot, and an operating component is provided on the air guide component that protrudes outside the housing or the fan cover.

[0019] Using the above solution, people can use the operating component to drive the air guide component to change the air outlet direction of the hair straightener. When the air guide component is tilted horizontally, it is kept in the current position by means of the limiting structure to prevent the air guide component from being displaced due to the inertia caused by the repeated movement of the hair straightener during combing.

[0020] Preferably, the operating component has a protruding paddle for the fingers to abut.

[0021] The above design, which combines the paddle and the control component, increases the contact area between the fingers and the control component, making it easier for people to push or turn the control component.

[0022] The second objective of this invention is to disclose a hair straightening comb, comprising a high-efficiency air outlet nozzle as described in any of the above embodiments, an opening at the bottom of the housing, a handle fixedly connected to the opening, an electric fan component for blowing air into the housing disposed inside the handle, and a heating component connected to the output end of the electric fan component.

[0023] By adopting the above solution, this solution combines the hair straightener with the nozzle in the above solution, which can significantly improve the conversion rate of effective airflow, thereby achieving the result of increased airflow and reduced energy consumption.

[0024] This invention, by employing the above technical solutions, has significant technical effects: when airflow blows towards the air outlet gap, the airflow that does not directly blow towards the air outlet gap will first impact the guide surface and change its flow direction along the guide surface, eventually converging with the airflow that directly blows towards the air outlet gap. Compared with the prior art, the guide component in this solution can effectively guide the airflow using the guide surface, reduce the velocity difference near the air outlet gap, and make the airflow blowing process smoother, thereby reducing wind resistance and improving the airflow efficiency of the hair straightener.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0028] Example 1 A type of hair straightening comb, based on Figure 1 , 8 As shown, the device includes a housing 1, on which an air outlet assembly is provided. The air outlet assembly has several vertically spaced air outlet gaps and a comb structure (not shown in the figures because the comb structure is prior art and would block the air outlet gaps). An opening 101 is provided at the bottom of the housing 1, and a handle 2 is fixedly connected to the opening 101. An electric fan component that blows air into the housing 1 is provided inside the handle 2. A heating component is connected to the output end of the electric fan component. The above structure is prior art, and for details, please refer to the Chinese patent with announcement number "CN119924631A" entitled "A Straight Hair Comb with Horizontal Air Outlet". These structures will not be described in detail in this embodiment.

[0029] The improvement in this embodiment lies in the spaced-apart flow-guiding components on the air outlet assembly. Each flow-guiding component has a flow-guiding surface 5 that connects to adjacent air outlet gaps and extends in an expanding manner relative to the air outlet gaps. According to... Figure 3 , 5 As shown in Figures 6 and 7, the flow diversion assembly includes flow diversion blocks 3 located between two adjacent air outlet gaps and distributed along the length of the air outlet gaps. The cross-section of the flow diversion block 3 is wedge-shaped, and the tip of the flow diversion block 3 faces away from the air outlet gap and is located in the middle between the two air outlet gaps. Flow diversion surfaces 5 are formed on both sides of the tip of the flow diversion block 3, respectively abutting against the two adjacent air outlet gaps. According to... Figure 3 As shown, the airflow diversion assembly also includes airflow diversion wings 4 located at the first and last ends of all airflow gaps, respectively, on the side away from the airflow diversion block 3. The airflow diversion wings 4 extend obliquely towards the side away from the airflow diversion block 3, and the side of the airflow diversion wings 4 facing the airflow diversion block 3 forms an airflow diversion surface 5, so that two funnel-shaped airflow diversion surfaces 5 are distributed on both sides of each airflow gap.

[0030] according to Figure 2 , 5As shown, the air outlet assembly includes a hood 6, on which a plurality of air outlets 601 are spaced apart to mate with the air outlet gap. A guide component 7 is movably disposed between the hood 6 and the diverting component 8, which drives the airflow to be horizontally tilted out from one side of the air outlet 601. The air outlet gap is formed on the guide component 7. A diverting component is fixedly protruding from the guide component 7. A diverting component 8 is fixedly disposed inside the housing 1 to evenly distribute the airflow to various parts of the air outlet assembly. The diverting component 8 includes a vertically arranged partition plate 801 inside the housing 1 and diverting plates 802 that are horizontally protruding on both sides of the partition plate 801 and distributed vertically at intervals. One side of the diverting plate 802 mates with the air outlet gap, and the other side is bent downward. A mating groove 9 is formed on the diverting component to engage with the diverting plate 802. The guide component 7 slides laterally with the diverting component 8 by means of the mating groove 9. Figure 3 , 7 As shown, in this embodiment, the flow guide block 3 located in the center is provided with a relief groove 10 for accommodating the lateral movement of the partition plate 801, so that the flow guide component 7 does not interfere with the position of the partition plate 801 when it slides laterally.

[0031] according to Figure 2 , 6 As shown in Figures 7 and 9, the air outlet gap includes a plurality of air guide grooves 702 formed by the recess of the side of the air guide component 7 facing the air outlet 601, and an air inlet groove 701 that is opened through the middle of the air guide groove 702 and has a width smaller than the air guide groove 702. The air inlet groove 701 slides back and forth between the two sides of the air outlet 601 with the air guide component 7 and is misaligned with the air outlet 601 through the air guide groove 702.

[0032] A limiting structure is provided between the air guide component 7 and the housing 1 to restrict the movement of the air guide component 7 after the air inlet slot 701 connects with the air outlet 601 through the air guide slot 702. Figure 5 As shown, the limiting structure includes a receiving groove 11 opened on the housing 1, a limiting pin 12 is provided in the receiving groove 11, and a spring 13 is provided between the limiting pin 12 and the bottom of the receiving groove 11. A pair of limiting grooves 14 are provided on the flow guiding component 7 for the limiting pin 12 to be elastically engaged. An operating member 15 protrudes from the flow guiding component 7 and passes through the wind cover 6. People can drive the flow guiding component 7 to slide laterally by moving the operating member 15, so that the air inlet groove 701 is respectively misaligned and connected to the two sides of the air outlet 601. At the same time as the connection, the limiting pin 12 will pop out and elastically abut against the limiting groove 14, thereby restricting the movement of the flow guiding component 7. When it is necessary to switch the air direction, simply move the operating member 15 to the other side.

[0033] Based on the above structure, refer to Figures 1-9It can be seen that the airflow guiding surfaces 5 on both sides of each air outlet gap on the hair straightener in this solution are distributed in the shape of a trumpet. When the airflow blows towards the air outlet gap, the airflow that does not blow directly towards the air outlet gap will first impact the airflow guiding surface 5 and change its flow direction along the airflow guiding surface 5. Finally, it will converge with the airflow that blows directly towards the air outlet gap and flow towards the air outlet gap. Compared with the prior art, the airflow guiding component in this solution can effectively guide the airflow using the airflow guiding surface 5, reduce the flow velocity difference near the air outlet gap, and make the airflow blowing process smoother, thereby reducing wind resistance and improving the airflow efficiency of the hair straightener.

[0034] Example 2 Based on Example 1, this example further defines a hair straightening comb, according to... Figure 10 As shown, the flow guide component 7 has a protruding operating member 15 that passes through the wind shroud 6, and a lever 1501 extends and protrudes from the operating member 15; according to Figure 1 , 2 As shown, the operating component in Embodiment 1 is a cubic protrusion with an anti-slip pattern on its surface. Since the exposed portion of the side of the operating component 15 is small, it is difficult to push the operating component 15 from the side. Therefore, when switching the wind direction, people usually use their index finger to press against the back of the housing 1 and then press the operating component 15 with their thumb before pushing it. In this embodiment, the lever design increases the force-bearing area on the side of the operating component 15. When people need to switch the wind direction, they only need to press their finger against one side of the lever 1501 and push or turn it to the other side, thereby achieving the purpose of easy operation.

[0035] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
