Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a hair dryer. Background Technology

[0002] Hair dryers, as a common personal care and household appliance, primarily function by using a motor to drive a fan to rotate, drawing in air and heating it through an electric heating element, ultimately blowing hot air out of the outlet to achieve purposes such as quick hair drying and styling.

[0003] Traditional hair dryers typically consist of basic components such as a motor, fan blades, heating element, housing, and handle. As users' demands for styling functions increase, some hair dryers are designed to switch airflow. For example, they can be detachably fitted with nozzles that produce different airflow effects, such as concentrator nozzles and diffuser nozzles, to provide different airflow experiences and ultimately meet the actual needs of users.

[0004] However, current hair dryers require external accessories to switch airflow modes. If users need to switch airflow modes, they must carry the hair dryer and multiple different nozzle accessories, which is very inconvenient.

[0005] Therefore, improvements to existing technologies are necessary.

[0006] The above information is provided as background information only to aid in understanding this disclosure and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this disclosure. Utility Model Content

[0067] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0068] In the description of this utility model, it should be understood that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component that is centrally positioned therein. When a component is considered to be "set" on another component, it can be directly set on the other component or there may be a component that is centrally positioned therein.

[0069] Furthermore, terms such as "long," "short," "inner," and "outer" indicate orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings. They are used only for the convenience of describing this utility model and do not indicate or imply that the device or component referred to must have this specific orientation or operate in a specific orientational configuration. Therefore, they should not be construed as limitations of this utility model.

[0070] The following is in conjunction with the appendix Figure 1-10 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0071] Example 1:

[0072] Please refer to Figure 1 and Figure 2 This utility model provides a hair dryer, including a hair dryer body, which includes a housing 1, a wind shield 2, and a press-locking component 3.

[0073] The housing 1 has an air outlet channel 100 inside, and one end is provided with a first air outlet 200 connected to the air outlet channel 100. The wind shielding component 2 is movably disposed on the housing 1 and is provided with a second air outlet 300 connected to the air outlet channel 100. The press-lock component 3 is movably disposed on the housing 1 along an axial direction and is connected to the wind shielding component 2. The press-lock component 3 is used to control the wind shielding component 2 to open or close the first air outlet 200.

[0074] For ease of understanding, a reference axis O is selected along the airflow outlet direction. The extension direction of the reference axis O is defined as the axial direction below. The pressing locking component 3 moves back and forth along the axial direction of this axis, thereby enabling power to be input by pressing. At the same time, the circumferential direction along the reference axis O is defined as the circumferential direction.

[0075] Based on this, when the user presses the locking component 3, the locking component 3 can push the windshield component 2 to move back along the reference axis. At this time, the windshield component 2 can move to the first position and the second position respectively along the axial direction. The windshield component 2 and the first air outlet 200 include at least the following two states:

[0076] The wind shield 2 moves to the first position, away from the first air outlet 200, so that the first air outlet 200 is opened. When the wind shield 2 opens the first air outlet 200, the airflow flows out from the first air outlet 200 and the second air outlet 300 respectively to obtain a larger air outlet area. At this time, the airflow can be dispersed more smoothly, which is equivalent to the hair dryer being in the mode of dispersed airflow.

[0077] When the wind shield 2 moves to the second position, the wind shield 2 covers the first air outlet 200, causing the first air outlet 200 to close. When the wind shield 2 closes the first air outlet 200, the airflow cannot flow out from the first air outlet 200. Therefore, the airflow can only flow out from the second air outlet 300. At this time, compared with the previous state, the air outlet area is reduced, the airflow is accelerated, and the air outlet path is more concentrated, which is equivalent to the hair dryer being in a concentrated air outlet mode.

[0078] The hair dryer provided in this application embodiment, by setting up a press-lock component 3 and a windproof component 2, can change the air outlet area by pressing, thereby quickly switching the air outlet mode of the hair dryer. The operation is convenient and efficient, without the need to disassemble or replace additional accessories. The problem of inconvenient airflow mode switching of the hair dryer is solved.

[0079] In some embodiments, refer to Figure 2 The hair dryer also includes a fan motor 4, which drives the airflow. Meanwhile, the housing 1 includes a mounting part 11 and a handle part 12.

[0080] The mounting part 11 is hollow inside. The first air outlet 200, the wind shielding component 2, and the pressing and locking component 3 are located in the mounting part 11. The handle part 12 is connected to the mounting part 11. The handle part 12 is hollow inside and communicates with the mounting part 11. The hollow interior of the mounting part 11 and the handle part 12 forms an air outlet channel 100. The handle part 12 is provided with an air inlet 121 that communicates with the air outlet channel 100. The fan motor 4 is located in the handle part 12 and is located in the air outlet channel 100.

[0081] Specifically, both the mounting part 11 and the handle part 12 are cylindrical structures. The length directions of the mounting part 11 and the handle part 12 are perpendicular to each other, and one end of the handle part 12 is connected to the periphery of the mounting part 11, thus forming a T-shaped shell 1.

[0082] At this time, the length direction of the mounting part 11 is consistent with the extension direction of the reference axis O. The mounting part 11 has two ends along the length direction, and the first air outlet 200 is disposed through one of the ends of the mounting part 11. In addition, since the air inlet is located on the handle part 12 and the fan motor 4 is located inside the handle part 12, when the fan motor 4 is started, a negative pressure difference can be formed in the air outlet channel 100. The airflow enters the handle part 12 from the air inlet 121 and flows to the mounting part 11. Finally, it flows out from the first air outlet 200 and / or the second air outlet 300 along the length direction of the reference axis O, thereby realizing airflow circulation, and the airflow is smooth and efficient.

[0083] In some embodiments, in order to enable the hair dryer to blow hot air, the hair dryer further includes a heating element 5, which is disposed in the mounting portion 11 and located within the air outlet duct 100.

[0084] Specifically, refer to Figure 2 and Figure 3 An installation sleeve 111 is provided inside the installation part 11. The installation sleeve 111 is hollow inside and open at both ends. There is a gap between the outer wall of the installation sleeve 111 and the inner wall of the installation part 11 so that the airflow can flow smoothly in the installation part 11. At the same time, an installation groove is provided on the outer wall of the installation part 11. The heating element 5 can be a sheet-shaped heating element 5, which is inserted into the installation groove to achieve installation. At this time, by connecting the heating element 5 to the power supply, the heating element 5 can generate heat and dissipate the heat to the gap between the installation sleeve 111 and the installation part 11. When the airflow passes through the gap, it carries away the heat, thereby forming hot air.

[0085] It is understood that the heating element 5 can be a nickel-chromium alloy heating wire or an alumina ceramic heating element. Any component that can generate heat when energized should be included in the scope of the explanation of the heating element 5 in this solution, and no specific restrictions are imposed here. In addition, a control system can be set up in the hair dryer. The control system has a conversion circuit. The heating element 5 is connected to the conversion circuit, and the conversion circuit is connected to the mains power. The conversion circuit is used to convert the mains power into a voltage value that can be used by the heating element 5 to achieve power supply. The specific principle of the heating element 5 will not be elaborated here.

[0086] Furthermore, in some embodiments, the number of heating elements 5 can be multiple, and the multiple heating elements 5 are arranged sequentially at intervals along the circumferential direction of the mounting sleeve 111. The number of heating elements 5 can be 4, 6 or 8, which can be adjusted according to actual needs, and no specific limitation is made here.

[0087] Based on the above settings, the multiple heating elements 5 can heat the airflow from multiple directions, so that the hot air can be delivered more evenly to the first air outlet 200 or the second air outlet 300, thus optimizing and improving the user experience.

[0088] Furthermore, referring to Figure 2 , Figure 4 as well as Figure 5 To enable the air outlet area to change quickly and efficiently, in some embodiments, the windproof assembly 2 includes a windproof bracket 21 and an elastic member 22. The windproof bracket 21 has a shielding portion 211, and a second air outlet 300 is disposed on the shielding portion 211. The shielding portion 211 is inserted into the first air outlet 200. When the shielding portion 211 is inserted into the first air outlet 200, the outer surface of the shielding portion 211 slides and seals against the inner wall of the first air outlet 200 in the circumferential direction. The elastic member 22 is connected to the windproof bracket 21 and the housing 1 respectively. When the first air outlet 200 is closed, the elastic member 22 is used to drive the shielding portion 211 to remain inserted into the first air outlet 200.

[0089] Specifically, the wind shield bracket 21 is slidably engaged with the mounting part 11 of the housing 1. Under the guidance of the housing 1, the wind shield bracket 21 can slide back and forth along the axial direction. During this process, the outline and size of the shielding part 211 on the wind shield bracket 21 are adapted to the opening outline and size of the first air outlet 200, so that the shielding part 211 can be inserted into the first air outlet 200. At the same time, the shielding part 211 located in the first air outlet 200 can be driven to slide and seal against the inner wall of the first air outlet 200 in the circumferential direction.

[0090] It needs to be explained that the sliding seal abutment means that the blocking part 211 can slide back and forth along the axial direction on the inner wall of the first air outlet 200. Furthermore, because the outline and size of the blocking part 211 are adapted to the opening outline and size of the first air outlet 200, when the blocking part 211 is inserted into the first air outlet 200, the blocking part 211 itself can completely block the first air outlet 200 (in conjunction with...). Figure 4 This prevents airflow from passing through the first air outlet 200 and forces it to exit only through the second air outlet 300 on the obstruction part 211, thereby reducing the air outlet area and increasing the airflow velocity. Correspondingly, when the obstruction part 211 leaves the first air outlet 200, airflow can exit simultaneously from both the first air outlet 200 and the second air outlet 300 (in combination with...). Figure 5 This increases the air outlet area and slows down the airflow speed.

[0091] In addition, the elastic element 22 is a spring, the length direction of the spring is consistent with the axial direction, and one end of the spring abuts against the inner wall of one end face of the mounting part 11, while the other end abuts against the wind shield bracket 21. At this time, the spring can provide elastic force to the wind shield bracket 21, and the wind shield bracket 21 tends to move towards the inner side of the mounting part 11. If the pressing locking component 3 is pressed down at this time, the pressing locking component 3 will push the wind shield bracket 21 away from the inner side of the mounting part 11. Then, the pressing locking component 3 is released, and the spring will push the wind shield bracket 21 to rebound. Based on the above settings, it is possible to determine whether the first air outlet 200 is blocked according to the pressing state of the pressing locking component 3, thereby realizing the gear adjustment function. Therefore, the setting of the spring is beneficial to the stability of the air outlet mode of the wind shield bracket 21.

[0092] Reference Figure 5 and Figure 6 To optimize the airflow experience, multiple first air outlets 200 are provided, and the multiple first air outlets 200 are arranged at intervals along the circumferential direction of the housing 1. At the same time, the wind shield bracket 21 also includes a main body 212 connected to the shielding part 211. The elastic member 22 is connected to the main body 212 and the housing 1 respectively. The number of shielding parts 211 is adapted to the number of first air outlets 200. The multiple shielding parts 211 are arranged at intervals along the circumferential direction of the main body 212, and the multiple shielding parts 211 are inserted and engaged with the multiple first air outlets 200 in a one-to-one correspondence.

[0093] Specifically, the number of first air outlets 200 can be four, six, or eight, etc., and can be adjusted according to actual design requirements. No limitation is made here. Four are set in this embodiment as an example. The main body 212 has a cylindrical structure and has two ends. The shielding part 211 is integrally connected to the periphery of the main body 212 and close to one end of the main body 212. Correspondingly, the number of shielding parts 211 is adapted to the number and arrangement of the first air outlets 200.

[0094] It should be explained that there are also multiple second air outlets 300, which are respectively set on multiple shielding parts 211.

[0095] Based on the above settings, by setting multiple first air outlets 200 spaced apart along the circumferential direction of the housing 1, airflow can be blown out in multiple directions in the circumferential direction of the blower, thus optimizing and improving the user experience. In addition, by setting multiple shielding parts 211, multiple first air outlets 200 can be opened and closed simultaneously. The second air outlets 300 set on the multiple shielding parts 211 can also ensure multi-directional air delivery in the air gathering mode, thus optimizing and improving the air delivery experience.

[0096] Reference Figure 7 , Figure 8 , Figure 9 as well as Figure 10 To enable the press-to-switch function for the air outlet mode, the press-lock component 3 includes a button 31, a push rod 32, a locking sleeve 33, and a stop lever 34.

[0097] Button 31 is movably mounted on housing 1 along the axial direction. The two ends of push rod 32 are connected to button 31 and windproof assembly 2 respectively. Button 31 pushes windproof assembly 2 back and forth through push rod 32 to open and close the first air outlet 200. Locking sleeve 33 is mounted on housing 1. Push rod 32 passes through locking sleeve 33. Wavy channel 6 is provided inside locking sleeve 33. Wavy channel 6 has a first recess 61 and a second recess 62 with different recess depths. Stop bar 34 is mounted on the outer circumference of push rod 32 and extends into wavy channel 6. While push rod 32 moves back and forth axially, wavy channel 6 guides stop bar 34 to reciprocate and engage with the first recess 61 and the second recess 62.

[0098] The button 31 is used for the user to press, thereby realizing power input. At this time, under the transmission of the push rod 32, the windproof component 2 can be pushed to move back along the axial direction, thereby realizing the opening and closing effect of the first air outlet 200 mentioned above.

[0099] In addition, the locking sleeve 33 is a sleeve structure with a hollow interior and open ends. The length direction of the locking sleeve 33 is consistent with the axial direction. The locking sleeve 33 is installed inside the mounting sleeve 111. Specifically, the inner edge of the mounting sleeve 111 and the outer edge of the locking sleeve 33 are both circular. At this time, the locking sleeve 33 can be inserted into the mounting sleeve 111, and the mounting sleeve 111 and the locking sleeve 33 can be fixed to each other to realize the installation of the locking sleeve 33. Usually, the locking sleeve 33 and the mounting sleeve 111 can be fixed with threaded fasteners. The specific installation method of the locking sleeve 33 is not limited here.

[0100] Furthermore, the locking sleeve 33 is used to lock the stop lever 34, thereby indirectly limiting the position of the push rod 32. Specifically, the wave channel 6 extends in a closed loop along the circumferential direction inside the locking sleeve 33, and the wave channel 6 undulates along the axial direction. At this time, the wave channel 6 forms two oppositely arranged sidewalls in the axial direction. At this time, the first recess 61 and the second recess 62 are both located on the sidewall of the wave channel 6 away from the first air outlet 200, and the depths of the first recess 61 and the second recess 62 in the circumferential direction are different.

[0101] Based on the above settings, when the user releases button 31, the elastic element 22 pushes the windproof bracket 21 to move towards the inside of the mounting part 11, thereby pushing the push rod 32 to move away from the first air outlet 200, and causing the stop lever 34 to fall into the first recess 61 or the second recess 62. At this time, because the depths of the first recess 61 and the second recess 62 in the axial direction are inconsistent, for example, the depth of the first recess 61 is greater than the depth of the second recess 62, the hair dryer is in different air outlet modes when the stop lever 34 falls into the first recess 61 or the second recess 62.

[0102] Specifically, when the lever 34 falls into the first recess 61, the push rod 32 falls back a greater distance than the second recess 62, thus enabling the shield 211 to be inserted into the first air outlet 200, the first air outlet 200 to remain closed, and the blower to be in the concentrated air mode.

[0103] Correspondingly, when the lever 34 falls into the second recess 62, the fall of the push rod 32 is smaller than that of the first recess 61. Therefore, the blocking part 211 cannot be inserted into the first air outlet 200 under the restriction of the second recess 62. The first air outlet 200 remains open, so the hair dryer is in the diffused air mode.

[0104] It should be explained that when the button 31 is pressed down, the lever 34 abuts against the side wall of the wave channel 6 near the first air outlet 200, and the side wall guides the lever 34 to swing in the circumferential direction and causes the push rod 32 to rotate synchronously, so that the lever 34 can switch from the first recess 61 to the second recess 62 or from the second recess 62 to the first recess 61.

[0105] Furthermore, referring to Figure 9 There are multiple first recesses 61 and multiple second recesses 62, and the multiple first recesses 61 and multiple second recesses 62 are arranged alternately along the circumferential direction of the locking sleeve 33, so that the stop lever 34 can achieve cyclic switching. The specific number of first recesses 61 and second recesses 62 can be adjusted according to actual needs, and no specific limit is made here.

[0106] Based on the above solution, by pressing down button 31, under the guidance of wave channel 6, the stop bar 34 on push rod 32 can be engaged with the first recess 61 or the second recess 62, thereby realizing the switching between the blower's air collection mode and air dissipation mode. The operation is quick and convenient, and the structure is ingeniously designed.

[0107] In some embodiments, refer to Figure 10The locking sleeve 33 includes a first assembly 331 and a second assembly 332. The first assembly 331 has a first protruding ring 3311, a first recess 61 and a second recess 62 located on the end face of the first protruding ring 3311. The second assembly 332 is connected to the first assembly 331 and has a second protruding ring 3321 inside. The end face of the second protruding ring 3321 is opposite to the first protruding ring 3311 and has a plurality of guide grooves 7 arranged sequentially along the circumferential direction. A wave channel 6 is formed between the first protruding ring 3311 and the second protruding ring 3321. The stop lever 34 is slidably engaged with the guide grooves 7. The guide grooves 7 are used to push the push rod 32 to rotate so that the stop lever 34 switches from the first recess 61 to the second recess 62 or the second recess 62 switches to the first recess 61.

[0108] Specifically, the first component 331 has a cylindrical shape, is hollow inside and open at both ends. A first protruding ring 3311 is integrally connected to one end of the first component 331. The end of the first protruding ring 3311 faces the location of the first air outlet 200. The first recess 61 and the second recess 62 are provided at the end face of the first protruding ring 3311. The push rod 32 passes through the hole inside the first component 331 and passes through the first component 331. The stop rod 34 extends to the relative position of the first recess 61 and the second recess 62. At this time, under the push of the elastic member 22, the stop rod 34 can fall into the first recess 61 or the second recess 62.

[0109] In addition, the second kit 332 also has a cylindrical structure. The second kit 332 is coaxially arranged with the first kit 331, and the ends of the two are fixedly connected to each other. Usually, a buckle can be provided between the first kit 331 and the second kit 332 to achieve the fixed connection between the two. No specific restrictions are made here.

[0110] Based on this, the second protruding ring 3321 is integrally connected with the second kit 332, and the end of the second protruding ring 3321 extends toward the side opposite to the first air outlet 200 and is arranged opposite to the first protruding ring 3311.

[0111] At this time, the guide groove 7 is recessed at the end face of the second convex ring 3321. The guide groove 7 has an inclined guide surface 71 and a third recess 72 adjacent to one end of the inclined guide surface 71. The inclined guide surface 71 spans two adjacent first recesses 61 and second recesses 62 in the circumferential direction, and the third recess 72 is opposite to the next first recess 61 or second recess 62 into which the stop bar 34 needs to be engaged.

[0112] Specifically, when the shift lever 34 needs to be engaged from the second recess 62 into the first recess 61, since the inclined guide surface 71 extends from the second recess 62 to the first recess 61, and the third recess 72 is opposite to the first recess 61, by pressing the button 31, the push rod 32 moves axially and abuts against the inclined guide surface 71. Under the guidance of the inclined guide surface 71, the push rod 32 rotates and the shift lever 34 falls into the third recess 72. At this time, the button 31 is released, and the elastic element 22 pushes the push rod 32 back down through the windproof bracket 21, and the shift lever 34 falls into the first recess 61, realizing the switching action. Correspondingly, the process of the shift lever 34 engaging from the first recess 61 into the second recess 62 is similar to the above process, and will not be described in detail here.

[0113] Based on the above settings, users can repeatedly switch between the concentrated air mode and the diffused air mode by pressing button 31 repeatedly.

[0114] In some embodiments, the external dimensions of the main body 212 are adapted to the shape of the opening of the second kit 332 near the first air outlet 200. At this time, the main body 212 is inserted into the second kit 332 and slides against its inner wall. The second kit 332 can also guide the displacement of the shielding bracket, making the displacement of the windshield bracket 21 more stable.

[0115] Reference Figure 8 The button 31 includes a pressing plate 311 and a connecting rod 312. The housing 1 is provided with a clearance hole for exposing the pressing plate 311. The connecting rod 312 is slidably disposed in the housing 1, with one end connected to the pressing plate 311 and the other end connected to the push rod 32.

[0116] Specifically, the pressing plate 311 is integrally connected with the connecting rod 312 to obtain good connection strength. In addition, the pressing plate 311 can be set as a circular button 31, a triangular button 31, a rectangular button 31, a polygonal button 31, or a petal-shaped button 31. The pressing plate 311 can produce different aesthetic shapes by adopting different outlines, and also has a large contact area, which makes it easy to press the button 31. Here, the outline of the button 31 is not limited.

[0117] In addition, the length direction of the connecting rod 312 is consistent with the axial direction, and one end of the connecting rod 312 abuts against one end of the push rod 32. At this time, by pressing the pressing plate 311, the connecting rod 312 can be pushed to move along the axial direction, thereby pushing the push rod 32 to move. The operation is simple and the start-up is quick.

[0118] Furthermore, looking back Figure 4 The housing 1 is provided with a first guide sleeve 8 that communicates with the clearance hole. The connecting rod 312 and the push rod 32 are located inside the first guide sleeve 8 and slide against the inner wall of the first guide sleeve 8 respectively.

[0119] Based on the above configuration, the first guide sleeve 8 can position the ends of the connecting rod 312 and the push rod 32, so that the two can be tightly abutted along the axial direction, and the two are not easy to deviate, making the fit more stable. In addition, the first guide sleeve 8 provides guidance for the button 31 and the push rod 32 respectively, so that the motion stability of the two is optimized and improved.

[0120] Furthermore, the windproof assembly 2 is provided with a second guide sleeve 9, and the end of the push rod 32 is inserted into the second guide sleeve 9 and slides against the inner wall of the second guide sleeve 9.

[0121] Specifically, the length of the second guide sleeve 9 extends along the axial direction. One end of the second guide sleeve 9 is connected to the main body 212 and is located on the side of the main body 212 facing the push rod 32. By inserting the end of the push rod 32 into the second guide sleeve 9, the second guide sleeve 9 can improve the connection stability between the push rod 32 and the windproof bracket 21, making the structure less prone to displacement and the pressure transmission more stable.
