SUMMARY OF THE INVENTION
[0006]
The purpose of the present invention is to provide an electric hair dryer, which can conveniently realize the switching of the hand-held-hands-free operation mode.
[0007]
According to the present invention, there is provided a hair dryer comprising a hair dryer body and a retaining member or retaining mechanism connected thereto, wherein the retaining member is configured to reversibly and rapidly transition between a handle and a holder by its own shape change. This rapid change in thinking makes it easy to switch between the hand-held-hands-free operation mode of the hair dryer.
[0008]
In the present invention, "the shape change of the holding member itself" refers to the change in the shape of the holding member itself, and does not include the case where the holding member has no substantial change in the structural shape, but only changes in the position relative to the hair dryer body, such as a pivot change of rotation position.
[0009]
According to a specific embodiment of the present invention, the holding member has a connecting end for connecting to the hair dryer body and another opposite free end (non-connecting end). The free end of the retaining member is configured to be rapidly expandable to increase its support surface for use as a stent. The holding member can be quickly switched from the original handle or transformed into a fixed bracket by enlarging and modifying its free end, thereby facilitating the transition to hands-free blowing operation.
[0010]
According to one embodiment of the invention, the retaining member may comprise at least one (preferably 2-4, eg three) flaps around its free end, acting as a handle when the flaps are not flared, and when the flaps are not flared outwards. It is used as a stand when it is opened (opening the umbrella). The holding member has a simple structure, and can switch or change the blowing mode very conveniently.
[0011]
Although other variants can also be used, such as quick connection (eg plugging in) the fixing seat or fixing plate at the free end of the holding member, or even popping or pulling out the expandable support plate or support rib from the free end, etc. , but the "open umbrella" deformation or modification of the present invention is obviously more advantageous in terms of structural integration and ease of use. Additionally, in such an "opening" embodiment of the invention, the distal end (expandable end) of the flap may be provided at the free end of the retaining member and expandable outwardly therefrom by 0-90° ("positive open end"). open" mode); or the proximal end of the tab (attached to the fixed end) can be positioned at the free end of the retaining member and the distal end of the tab can be flared or flipped 90-180° toward the free end of the retaining member ( "Inverted" mode). Compared with the "reverse opening" mode structure, the "positive opening" mode structure is simpler and more convenient to operate; however, the "reverse opening" mode structure can extend or increase the length of the retaining member (within the approximate length of the fins), so that the Adjust the blowing height.
[0012]
In addition, a hollow handle may be integrally formed in the hair dryer body, and the holding member of the present invention may be accommodated therein so as to be able to be pulled out or ejected. By accommodating the holding member in the hollow handle, the holding member can be converted into a handle; by pulling out the holding member from the hollow handle and expanding and remodeling its free end, the handle can be converted into a fixed bracket.
[0013]
According to a further preferred embodiment of the present invention, the distal ends of the fins may also be substantially on the same supporting surface as the free ends of the retaining members when they are flared out for use as a stent. This structure makes the support stronger.
[0014]
Additionally, the free end of the retaining member may be provided with suction cups or friction pads. The distal ends of the fins may also be provided with friction pads, respectively. This structure can further enhance the support stability.
[0015]
According to a further preferred embodiment of the present invention, the holding member is telescopic in its longitudinal direction, for example, the holding member is configured as a telescopic telescopic or multi-stage antenna structure. This structure can realize convenient adjustment of the blowing height. The telescopic sleeve can be designed to be able to adjust its telescopic length and stay fixed at any length; or it can be designed as a graded positioning sleeve so that it can stay fixed at different length setting positions.
[0016]
According to the hair dryer of the present invention, the holding member is preferably articulated to the hair dryer body. The movable connection method is convenient to adjust the blowing angle and blowing direction. Here, the body of the hair dryer is relative to the holding member, and includes a casing, various components located in the casing, and various accessories that are stationary on the casing, and the like.
[0017]
The above-mentioned active connection mode can be either a detachable connection or an inseparable connection.
[0018]
According to one embodiment of the inseparable articulating connection, the holding member can be pivoted to the blower body by means of a hinge. The pivotal connection allows the holding member not only to conveniently adjust the blowing angle when used as a stand, but also to fold the holding member relative to the hair dryer body for portability or to store the holding member in a suitable position on the hair dryer body for storage. The hinge can be a hinge that can be positioned at any pivot angle, so that it can be pivoted arbitrarily and stay fixed at the current pivot position; or a graded positioning hinge can be used, which can be pivoted and positioned at different settings angle.

In this case, the receptacle may be provided on one of the blower body and the holding member, and the friction ball may be connected to the other of the blower body and the holding member through a link.
[0024]
Where the retaining member is articulated to the hair dryer body, the retaining member can be retracted relative to the hair dryer body to enable the entire hair dryer to have a single continuous cylindrical shape such as a cylindrical, elliptical, spindle or rectangular tube when not in use shape.
[0025]
In the case where the holding member is inseparably articulated to the blower body, at least a portion of the blower body may have a missing barrel cross-section, when the holding member is fully retracted relative to the blower body (contracted to an initial minimum volume state), the cross-section of the holding member is the same as that of all the blower body. The barrel cross-sections of at least a portion of the blower body are complementary in shape to form a substantially complete barrel section.
[0026]
Further, the hair dryer body may include a front cylinder working part and a rear cylinder receiving part arranged in a straight line, the front cylinder working part is used to perform a blowing operation function and the rear end of the front cylinder working part is formed with an air inlet, and the rear cylinder receiving part is formed with a The air inlet cavity in which the power cord that will provide power to the working part of the front cylinder is stored, and the air inlet cavity is communicated with the air inlet of the working part of the front cylinder. The working part of the front cylinder has a complete cylinder section, and the receiving part of the rear cylinder is relatively The barrel working portion has a defective barrel section, and when the retaining member is fully retracted and retracted relative to the rear barrel receiving portion, the cross-section of the retaining member complements the barrel cross-sectional shape of the rear barrel receiving portion to form a substantially complete barrel section consistent with the front barrel working portion .
[0027]
In the case where the holding member is detachably and movably connected to the hair dryer body, the hair dryer body may include a front barrel working part for performing a blowing operation function and a rear end of the front barrel working part and a rear barrel receiving part that are linearly arranged. An air inlet is formed, and the rear barrel receiving part is formed with an air inlet cavity for receiving the power cord for supplying power to the front barrel working part, and the air inlet cavity is communicated with the air inlet of the front barrel working part, and the front barrel working part is formed. The barrel sectional shape is substantially continuous with the rear barrel accommodating portion, and the rear barrel accommodating portion is also used for accommodating the separated holding member therein. In addition, the rear barrel storage part can also be detachably or detachably connected to the front barrel working part, so that the hair dryer becomes lighter in use by removing the rear barrel storage part.
[0028]
The above single cylindrical structure makes the hair dryer of the present invention very simple and beautiful in a non-use state such as storage, which not only minimizes the occupied space, but also eliminates the trouble caused by messy power cords.
[0029]
In addition, the hair dryer of the present invention may further include a cover for covering at least the rear end of the rear barrel accommodating portion when the power cord or the holding member is accommodated in the cavity of the rear barrel accommodating portion.
[0030]
