Description

Technical Field

[0001] This utility model relates to the technical field of household appliances, specifically to a hair styling tool. Background Technology

[0002] Hair styling appliances, such as hair dryers, generate hot air to dry hair, clothes, and other items. The required airflow varies depending on the specific usage scenario. Traditional hair dryers typically have different speed settings, such as low and high speeds, and adjusting these settings requires manual adjustment. For example, to change from speed 1 to speed 3, one must first adjust from speed 1 to speed 2, then from speed 2 to speed 3; resetting requires the reverse process, adjusting from speed 3 to speed 2, then from speed 2 to speed 1. Each adjustment requires the user to apply force, making it inconvenient, time-consuming, and laborious, resulting in a poor user experience. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the main purpose of this utility model is to provide a hair styling tool that solves the problem that traditional hair styling tools are difficult to operate and inconvenient to use when adjusting different working modes, which affects the user experience.

[0017] When in the second working position, the locking force of the switch head at its position is greater than the elastic force of the elastic telescopic member, and the push button remains in the second working position; when in the third working position, the elastic restoring force of the elastic telescopic member is greater than the locking force of the switch head, driving the push button to move from the third working position to the second working position.

[0018] Optionally, the handle assembly includes an inner handle cylinder and an outer handle cylinder sleeved on the outside of the inner handle cylinder. The inner handle cylinder is provided with a receiving groove, the button plate is disposed in the receiving groove, and the sliding plate is slidably disposed at the opening of the receiving groove.

[0019] The first through hole is provided on the outer cylinder of the handle, and the first through hole is opposite to the opening of the receiving groove.

[0020] Optionally, the inner cylinder of the handle includes a first half-cylinder and a second half-cylinder connected to each other, and the receiving groove is located on the outside of the first half-cylinder and close to the pivot structure;

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

If the specific posture changes, the directional indication will also change accordingly.

[0042] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0043] This utility model provides a hair styling tool 100, which can be configured as any one of a hair dryer, curling iron, straightening comb, etc. For ease of explanation, the following description will mainly use a hair dryer as an example to illustrate a specific embodiment. Other devices can be adapted accordingly.

[0044] Specifically, please refer to Figures 1 to 3 In this embodiment, the hair styling appliance 100 includes a hair dryer assembly 1, a handle assembly 2, a pivot structure 3, and a switch assembly 4. The pivot structure 3 pivotally connects the hair dryer assembly 1 and the handle assembly 2, allowing them to rotate relative to each other. The switch assembly 4 is disposed on the handle assembly 2 and close to the pivot structure 3. The switch assembly 4 has a push button 41 at least partially exposed on the outside of the handle assembly 2. The push button 41 is movable relative to the handle assembly 2 to have a first working position, a second working position, and a third working position. The push button 41 moves along a first direction under the action of an external force, moving from the first working position to the second working position. When the push button 41 is in the second working position and is subjected to a continuous force along the first direction, the push button 41 can move to the third working position. When the force on the push button 41 is removed at the third working position, the push button 41 automatically returns to the second working position from the third working position.

[0045] In this embodiment, the hair dryer assembly 1 and the handle assembly 2 are rotatably connected by the pivot structure 3, allowing the hair dryer assembly 1 and the handle assembly 2 to rotate relative to each other and operate at different angles. For example, the hair dryer assembly 1 and the handle assembly 2 can be in a straight, extended state, or the angle between the hair dryer assembly 1 and the handle assembly 2 can be 90° or less, resulting in more diverse working modes for the hair styling appliance 100 and making it easier to store. Furthermore, a switch assembly 4 is provided on the handle assembly 2. When using the hair styling appliance 100, the user holds the handle assembly 2, and the switch assembly 4 is located on the handle assembly 2, making it easier for the user to operate with one hand and adjust the working mode of the hair styling appliance 100 more convenient. Furthermore, the switch assembly 4 has a first working position, a second working position, and a third working position. When the switch assembly 4 is in different working positions, the hair styling appliance 100 is in different working modes, such as cold air mode, hot air mode, low wind speed mode, or high wind speed mode, so that the hair styling appliance 100 can better adapt to the user's usage needs. Moreover, when the force on the push button 41 is removed in the third working position, the push button 41 can automatically reset from the third working position to the second working position. This allows the switch assembly 4 to automatically reset without manual adjustment by the user when switching from the third working position to the second working position, making the adjustment between gears easier and the reset time shorter. This makes the switching of the working mode of the hair styling appliance 100 faster and improves the user experience.

[0046] It should be noted that when the push button 41 is in the first working position, the hair styling appliance 100 is in the first working level; when the push button 41 is in the second working position, the hair styling appliance 100 is in the second working level; and when the push button 41 is in the third working position, the hair styling appliance 100 is in the third working level. Each working level corresponds to a different working mode. For example, off mode, cool air mode, hot air mode, low-speed blow-drying mode, high-speed blow-drying mode, alternating hot and cold mode, etc. The hair styling appliance 100 can be set to correspond to the above-mentioned working modes for each level according to the actual user's needs, and no specific limitation is made here.

[0047] The push button 41 is slidably mounted on the handle assembly 2. Preferably, the first working position, the second working position, and the third working position are arranged sequentially along the axial direction of the handle assembly 2. When the user holds the handle assembly 2, they can better push the push button 41 with their thumb to move it in a direction perpendicular to the gripping direction (i.e., the axial direction of the handle assembly 2), making it easier for the user to adjust the various working positions. When the hair styling appliance 100 is in normal use, the handle assembly 2 extends vertically, and the first working position, the second working position, and the third working position are arranged sequentially from top to bottom. Unless otherwise specified, the descriptions of orientations in this utility model shall be taken as above.

[0048] Specifically, in combination Figures 3 to 5 As shown, the push button 41 includes a slide plate 411 and a button 412. The slide plate 411 is slidably mounted on the handle assembly 2. A first through hole 221 is provided on the handle assembly 2, and the button 412 is detachably mounted on the slide plate 411 and located within the first through hole 221. At least a portion of the button 412 is exposed through the first through hole 221 to facilitate user operation. When the button 412 moves relative to the first through hole 221 under external force, it can drive the slide plate 411 to move together, thereby adjusting the gear position through the slide plate 411.

[0049] Furthermore, the switch assembly 4 also includes a button plate 42 disposed on the handle assembly 2, and a switch head 43 movably disposed on the button plate 42. A sliding plate 411 is connected to the switch head 43, which has three positions corresponding to the first, second, and third working positions of the push button 41, respectively. The user pushes the button 412, causing the sliding plate 411 to move as well, thereby acting on the switch head 43 to switch between different positions. The button plate 42 and the switch head 43 can be formed in a mechanical switch; the working principle of a mechanical switch is conventional and will not be explained in detail here.

[0050] Moreover, combined Figure 4 and Figure 6 As shown, the switch assembly 4 also includes a reset member 44. When the push button 41 is in the third working position and the external force on the button 412 is removed, the reset member 44 can drive the slide plate 411 from the third working position to the second working position. That is, after the slide plate 411 is in the third working position, if the user no longer applies force to the button 412, the slide plate 411 can automatically move from the third working position to the second working position under the action of the reset member 44, without the need for manual adjustment by the user. The hair styling appliance 100 can automatically reset from the third working position to the second working position, making operation easier and simpler. The reset of the slide plate 411 is also faster, and the switching of the working mode of the hair styling appliance 100 is more efficient.

[0051] The hair styling appliance 100 also includes a circuit board and a suction device located within the handle assembly 2. A button panel 42 is mounted on the circuit board and electrically connected to the suction device. By switching the switch head 43 on the button panel 42 to different positions, the suction device can be controlled to operate, thereby adjusting the airflow speed or turning off the hair styling appliance 100.

[0052] Preferably, combined with Figure 6 and Figure 7As shown, the reset member 44 is configured as an elastic telescopic member 441. In the second working position, the locking force of the switch head 43 at its position is greater than the elastic force of the elastic telescopic member 441, and the push button 41 remains in the second working position. When the push button 41 is in the second working position, the user does not need to provide a continuous force to the button 412, and the hair styling appliance 100 can still operate in the second working position. In the third working position, the elastic restoring force of the elastic telescopic member 441 is greater than the locking force of the switch head 43, driving the push button 41 to move from the third working position to the second working position. Because the elastic storage capacity of the elastic telescopic member 441 is greater in the third working position than in other working positions, and is greater than the locking force of the switch head 43 itself, the elastic telescopic member 441 can push the slide plate 411 to move, causing the slide plate 411 to move from the third working position to the second working position. The elastic telescopic member 441 can be configured as a telescopic spring or an elastic rubber component, etc.

[0053] Of course, in other embodiments, the reset member 44 may also be configured as an elastic arm or other mechanism reset structure, so as to automatically reset the slide plate 411 by using the elastic arm to abut against it.

[0054] At this time, the third working position can be set to an infrequently used working mode, allowing the user to quickly switch between the third and second working positions, avoiding the need to repeatedly adjust button 412. For example, the third working position can be set to a cold air mode or a hot / cold alternating mode. Since the cold air mode or hot / cold alternating mode is generally used for a shorter period of time, the user can apply a certain amount of force to button 412 in this working mode, and can quickly switch from this infrequently used working mode to the normal working mode, improving the response speed of the hair styling appliance 100 in switching working modes. Moreover, since the locking force of the switch head 43 is not large, this automatic reset mode can effectively prevent the slide plate 411 from switching directly from the third working position to the first working position due to excessive force from the user, which would require the user to repeatedly adjust the position and affect the user experience.

[0055] Furthermore, such as Figure 3As shown, in terms of the specific structure of the handle assembly 2, the handle assembly 2 includes an inner handle cylinder 21 and an outer handle cylinder 22 sleeved on the outside of the inner handle cylinder 21. The inner handle cylinder 21 has a receiving groove 2111, the button plate 42 is disposed within the receiving groove 2111, and the slide plate 411 is slidably disposed at the opening of the receiving groove 2111. Through the cooperation of the inner handle cylinder 21 and the outer handle cylinder 22, both the button plate 42 and the slide plate 411 are covered inside the handle assembly 2, allowing only the button 412 to be exposed. This makes the overall appearance of the handle assembly 2 more aesthetically pleasing and better protects the switch assembly 4. A first through hole 221 is provided on the outer handle cylinder 22, and the first through hole 221 is opposite to the opening of the receiving groove 2111, allowing the button 412 to be connected and fixed to the middle of the slide plate 411. Furthermore, the middle area of ​​the slide plate 411 can better connect with the switch head 43, ensuring a more balanced force applied to the switch head 43.

[0056] Furthermore, combined Figure 3 and Figure 4 As shown, the inner cylinder 21 of the handle includes a first half-cylinder 211 and a second half-cylinder 212 connected to each other. A receiving groove 2111 is located on the outside of the first half-cylinder 211 and near the pivot structure 3. One of the first half-cylinder 211 and the second half-cylinder 212 has multiple hooks 2121, and the other has multiple fasteners 2113. The multiple hooks 2121 and the multiple fasteners 2113 are engaged one-to-one to connect and fix the first half-cylinder 211 and the second half-cylinder 212. The outer cylinder 22 of the handle is sleeved on the outside of the first half-cylinder 211 and the second half-cylinder 212, with the first through hole 221 facing the receiving groove 2111. This better conceals the mounting structure on the outside of the inner cylinder 21 of the handle, making the appearance of the handle assembly 2 more aesthetically pleasing, and also better ensuring accurate alignment between the outer cylinder 22 and the inner cylinder 21.

[0057] The outer cylinder 22 of the handle is roughly cylindrical with openings at both ends. (Recombined) Figure 3 and Figure 4 As shown, multiple air passage holes are provided at the end of the inner cylinder 21 of the handle away from the receiving groove 2111, and the multiple air passage holes are arranged to protrude from the end opening of the outer cylinder 22 of the handle. The handle assembly 2 also includes a filter cylinder 23, which is sleeved on the end of the inner cylinder 21 that extends out of the outer cylinder 22 of the handle, and is provided with an air inlet 231 that communicates with the multiple air passage holes. External airflow can pass through the filter cylinder 23 through the multiple air inlet holes 231 and enter the inner side of the inner cylinder 21 of the handle through the multiple air passage holes. Thus, under the action of the suction device of the hair styling appliance 100, the airflow can flow through the inner side of the handle assembly 2 and enter the air blower assembly 1 through the pivot structure 3. After being heated by the heating component inside the air blower assembly 1, the air is blown out from the air outlet of the air blower assembly 1 for the user.

[0058] To ensure better adjustment of the feel, preferably, combined with Figures 5 to 7 As shown, the slide plate 411 includes a main body 4111, two sliding arms 4112 protruding from the bottom of the main body 4111, and two clamping arms 4113 protruding from the bottom of the main body 4111. Each sliding arm 4112 extends axially along the handle assembly 2, and the two clamping arms 4113 are spaced apart relative to each other along the axial direction of the handle assembly 2 to clamp the switch head 43 on both sides. The movement of the slide plate 411 drives the switch head 43 to move, thereby adjusting the gear position. The receiving groove 2111 has two opposing support arms on its sidewall, each with a corresponding sliding groove. The two sliding arms 4112 are slidably engaged within the two sliding grooves. These sliding grooves guide and support the two sliding walls, ensuring greater stability and preventing wobbling during movement of the slide plate 411.

[0059] A second through hole 4114 is provided on the main body 4111. The button 412 is engaged in the second through hole 4114 and extends out from the first through hole 221, making it convenient for the user to adjust the button 412. During assembly, the slide plate 411 can be installed on the inner cylinder 21 of the handle first, and then the outer cylinder 22 of the handle can be fitted onto the outside of the inner cylinder 21 of the handle. Then, the button 412 is engaged in the second through hole 4114 from the first through hole 221. This makes the assembly operation of the switch assembly 4 not limited by the narrow internal space of the outer cylinder 22 of the handle, making the assembly operation more convenient.

[0060] Furthermore, multiple reinforcing ribs are provided on the side of the board body 4111 facing the inner cylinder 21 of the handle, and a protruding post is provided on the upper end of one of the reinforcing ribs. The protruding post is used to connect with the elastic telescopic member 441, so that the elastic telescopic member 441 can better abut against the slide plate 411 and the first half cylinder 211.

[0061] Preferably, combined with Figure 1 and Figure 2 As shown, during the relative rotation of the hair dryer assembly 1 and the handle assembly 2, the central axis of the hair dryer assembly 1 and the central axis of the handle assembly 2 are always located on the same plane. The support between the hair dryer assembly 1 and the handle assembly 2 remains aligned during rotation. Therefore, when rotating the hair dryer assembly 1 by holding the handle assembly 2, the hair dryer assembly 1 will not tilt to one side, making it easier and less strenuous to rotate, and providing a better user experience. Furthermore, it does not occupy excessive space along the axis of the pivot structure 3, resulting in a more compact size for the hair styling appliance 100.

[0062] In one embodiment, the lengths of the air duct assembly 1 and the handle assembly 2 are approximately the same along their respective axes. When folded, the ends of the air duct assembly 1 and the handle assembly 2 are aligned, thus making them more neat and compact to store.

[0063] In another embodiment, the axial length of the air duct assembly 1 is less than the axial length of the handle assembly 2. Since the air duct assembly 1 is the air outlet, setting the length of the air outlet to be shorter will result in a shorter flow path for the hot airflow formed after the airflow is heated by the heating component, resulting in less heat loss and thus higher airflow efficiency.

[0064] The shape and size of the hair dryer assembly 1 and the handle assembly 2 are not specifically limited, and can be square, polygonal, or irregular in shape. Preferably, both the hair dryer assembly 1 and the handle assembly 2 are cylindrical and have the same diameter, so that the hair styling appliance 100 has a more symmetrical and aesthetically pleasing shape and is more comfortable to hold when the hair dryer assembly 1 and the handle assembly 2 are in a bent or extended state.

[0065] Moreover, when in the extended state, one end of the air blower assembly 1 and the handle assembly 2 are opposite to each other, which allows one end of the air blower assembly 1 and one end of the handle assembly 2 to be better connected, while the other end of the air blower assembly 1 and the other end of the handle assembly 2 are far apart, and the angle between the central axis of the air blower assembly 1 and the central axis of the handle assembly 2 is in an obtuse angle and close to a straight angle.

[0066] If the air duct assembly 1 and the handle assembly 2 are set to rotate on a horizontal plane, then preferably, the pivot axis of the pivot structure 3 is set in the vertical direction. When in the extended state, the pivot axis of the pivot structure 3 is perpendicular to the central axis of the air duct assembly 1 and / or the central axis of the handle assembly 2, so that the air duct assembly 1 and the handle assembly 2 rotate more smoothly and are not easy to twist or shake.

[0067] Specifically, when rotating from the extended state to the bent state, the first side of the air duct assembly 1 and the first side of the handle assembly 2 move towards each other. In the extended state, on the orthographic projection along the axis of the pivot structure 3, the projections of the air duct assembly 1 and the handle assembly 2 are both located on the same side of the projection of the plane containing the pivot axis of the pivot structure 3; that is, the first side of the air duct assembly 1 and / or the first side of the handle assembly 2 are both located on the plane containing the pivot axis, or both are located on the first side of the plane containing the pivot axis. When the diameters of the air duct assembly 1 and the handle assembly 2 are equal, in the extended state, the first side of the air duct assembly 1 and the first side of the handle assembly 2 are flush, and the pivot axis is exactly located on the plane containing the first side of the air duct assembly 1 and the first side of the handle assembly 2. This allows the air duct assembly 1 and the handle assembly 2 to rotate more effectively while rotating in the same plane.

[0068] Alternatively, the pivot axis of the pivot structure 3 is located exactly on the straight line of the first side of the air duct assembly 1 and / or the handle assembly 2. In the radial direction along the air duct assembly 1 and / or the handle assembly 2, the portion of the pivot structure 3 protruding from the air duct assembly 1 and / or the handle assembly 2 is less, thus making the structure more compact in the radial direction and thus smaller in volume.

[0069] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
