Fig. 4 is a structural view of a baffle plate according to a first embodiment of the present invention. Fig. 5 is a structural view illustrating an air inlet part according to a first embodiment of the present invention. Fig. 6 is a sectional view showing a neck-hung type air blowing device according to a first embodiment of the present invention. The specific structure of the baffle, the air inlet portion according to the first embodiment of the present invention is described in detail below with reference to fig. 4 to 6.

And a baffle 60 disposed opposite to the intake opening 41 and located inside the intake opening 41. The baffle 60 is spaced apart from the air inlet 41, that is, the baffle 60 does not abut against the air inlet 41. Specifically, as described above, the air inlet 41 and the air inlet 51 are disposed opposite to each other, and the baffle 60 is disposed between the air inlet 51 and the air inlet 41, so that the air entering from the air inlet 41 can flow around the edge of the baffle 60 to the air supply unit 50, and thus, the hair of the wearer can be prevented from being brought into the air supply unit 50 after entering the air inlet 41 along with the air flow, and the use experience of the wearer is affected. The baffle 60 is matched to the air inlet 41 in shape, for example, when the air inlet 41 is circular, the baffle 60 is correspondingly circular. When the baffle 60 and the air inlet 41 are both circular, the diameter of the baffle 60 is larger than that of the air inlet 41. In addition, the baffle 60 has a diameter larger than that of the inlet 51 to cover the inlet 51, that is, the edge of the baffle 60 extends beyond the edge of the inlet 51 to prevent hairs entering with the air flow from being directly taken into the inlet 51. The embodiments of the present invention are described in terms of the air inlet 41, the air inlet 51, and the baffle 60 being circular. In addition, in other embodiments of the present invention, the intake vent 41, the intake port 51, and the baffle 60 may have other shapes such as a square, a rectangle, an oval, and the like, in which case the baffle 60 has a size larger than the intake port 51 and the intake vent 41 to cover the intake port 51 and the intake vent 41.

The baffle 60 includes a protrusion 61 and an outer peripheral portion 62.

And an outer peripheral portion 62 formed on the outer periphery of the baffle 60 and surrounding the edge of a projection 61 described later, the outer peripheral portion 62 extending beyond the edges of the air inlet 51 and the air inlet 41.

The protrusion 61 is formed in the center of the baffle 60 and protrudes from the outer peripheral portion 62 toward the intake port 41, that is, from the intake port 51 toward the intake port 41. Specifically, the projection 61 may gradually decrease in size from the outer peripheral portion 62 toward the center of the baffle 60 and gradually protrude toward the intake opening 41 or the outside of the intake opening 41. That is, the protrusion 61 may have an inclination of inclination from the central portion of the baffle 60 to the outer peripheral portion 62, and may be formed as an inclined plane or an inclined curved surface, for example. The protrusion 61 protrudes outside the air inlet 41, so that the hair of the wearer outside the air inlet 41 can flow along the slope of the protrusion 61 toward the outer peripheral portion 62 when entering the air inlet 41 along with the airflow direction, and since the outer peripheral portion 62 of the baffle 60 extends outside the edge of the air inlet 51, the hair flowing to the outer peripheral portion 62 can be blocked by the outer peripheral portion 62 on the outside of the baffle 60 and cannot enter the air inlet 51.

And an air inlet portion 70 disposed outside the air inlet 41 and opposite to an edge of the air inlet 41. Specifically, the inlet portion 70 may be connected to the baffle 60 by the engaging portion 80, but the present invention is not limited thereto, and the inlet portion 70 may be fixedly connected to other structures. A gap is provided between the air inlet 70 and the edge of the air inlet 41, that is, the air inlet 70 is not attached to the air inlet 41. The air inlet portion 70 may be formed in a ring shape, and a first air opening 71 entering from an outer edge of the air inlet portion 70 and a second air opening 72 entering from an inner edge of the air inlet portion 70 are formed. That is, the first air opening 71 corresponds to the interval between the air inlet 70 and the edge of the air inlet 41, and the second air opening 72 corresponds to the protrusion 61. The shape of the air inlet portion 70 may correspond to the shape of the air inlet 41, for example, in the case where the air inlet 41 is formed in a circular shape, the air inlet portion 70 may be provided in a circular ring shape. In addition, the air inlet portion 70 may be provided in a rectangular ring, a square ring, an elliptical ring, or the like according to the shape of the air inlet 41.

The air inlet portion 70 is connected to the baffle 60 by a plurality of engaging portions 80, and the engaging portions 80 penetrate the air inlet 41 and are disposed between the baffle 60 and the air inlet portion 70 to connect the baffle 60 and the air inlet portion 70. The engaging portion 80 includes an insertion portion 81 and an inserted portion 82.

The fitting portion 81 is provided on the inner surface of the air inlet portion 70 and extends from the inner side of the air inlet portion 70 toward the baffle 60. The insertion portion 81 includes a hook-shaped structure that extends from the inner surface of the air inlet portion 70 toward the baffle 60, and the extending end of the hook-shaped structure is capable of engaging with a slot described later to connect the air inlet portion 70 and the baffle 60.

The fitted portion 82 is provided on the outer surface of the shutter 60 and detachably engaged with the fitting portion 81. Specifically, the fitted portion 82 extends from the outer side of the outer peripheral portion 62 of the baffle 60 toward the air inlet portion 70. The inserted portion 82 includes a card slot to be engaged with the card strip. The cross section of the clamping groove corresponds to that of the clamping strip so as to be clamped with the clamping strip. For example, the cross-section of the card slot is in the shape of a letter.

The embedded portions 82 are provided in the same number as the embedded portions 81, and at least one of the pairs of the card bars and the card slots that are engaged with each other has a different engagement direction. That is, when the card slots face clockwise, at least one card slot faces counterclockwise. After the fitting portion 81 is fitted into the fitted portion 82, the air inlet portion 70 is fixed to the baffle 60, and the air inlet 41 is positioned between the baffle 60 and the air inlet portion 70. That is, the fitting portion 81 fixed to the inner surface of the air inlet portion 70 is engaged with the fitted portion 82 provided in the baffle 60 through the air inlet 41. Note that the present invention is not limited to a specific engaging structure and engaging manner of the engaging portion 80, and other engaging structures and engaging manners may be adopted. In addition, the inlet portion 70 may be connected to other positions by other connection structures.

The neck hanging type air supply device 10 is provided with a support part 20 and air supply parts 30 which are respectively and rotatably connected with two ends of the support part 20, and the directions of the air inlet 41 and the air outlet 42 can be changed through the rotation of the air supply parts 30, so that air supply is provided for a wearer in a multi-angle manner. In the rotation process, the plane of the air inlet 41 is parallel to the horizontal direction, or perpendicular to the horizontal direction, or forms a certain included angle with the horizontal direction. When a wearer wearing long hair wears the neck-hung air blower 10 around his neck, the hair is sucked into the air inlet 41 along with the air flow and then contacts the baffle 60 inside the air inlet 41. When the air blowing part 30 is rotated such that the air inlet 41 is parallel to the horizontal plane, the hairs are introduced into the housing 40 from the air inlet 41 vertically from the direction of the baffle 60. In this case, since the baffle 60 is provided between the air inlet 51 and the air inlet 41 and the baffle 60 is provided with the protrusion 61 protruding toward the air inlet 41, the hairs can be dispersed from the air inlet 41 to the edge of the air inlet 51 without entering the air inlet 51 according to the inclination of the protrusion 61.

Further, when the air supply part 30 is rotated such that the air inlet 41 is perpendicular to the horizontal plane, since the baffle 60 is disposed between the air inlet 41 and the air inlet 51 and the diameter of the baffle 60 is greater than the diameter of the air inlet 51 and the air inlet 41, the cross section of the baffle 60 and the cross sections of the air inlet 41 and the air inlet 51 form a structure of a "mountain" shape. Therefore, even if hairs enter the housing 40 from the air inlet 41 and contact the baffle 60, the hairs pass the edge of the baffle 60 and enter the space between the baffle 60 and the air inlet 51 to be blown to the air blowing unit 50. Therefore, the hair can be prevented from influencing the service performance of the hanging neck type air supply device 10, the hair is prevented from being wound into the fan blades along with the flowing of air, and the use feeling of a wearer is improved.

In addition, since the baffle 60 is disposed between the air inlet 41 and the air inlet 51, the distance between the baffle 60 and the air inlet 41 does not need to be set short to prevent the entry of hair, that is, even if the distance between the air inlet 41 and the baffle 60 is appropriately increased, the entry of hair into the air blowing unit 50 from the air inlet 51 can be prevented, so that the usability of the fan blades can be ensured while achieving an increase in the air volume. Moreover, the distance between the baffle 60 and the air inlet 41 is increased, so that the whistle sound caused by too short distance can be avoided.

Further, a projection 61 projecting from the outer peripheral portion 62 toward the intake port 41 side is provided at a position of the baffle 60 facing the intake port 51, that is, at a middle portion of the baffle 60. When the air bypasses the baffle 60, and enters the space between the baffle 60 and the air inlet 51, the air stays at the outer side of the air inlet 51. At this time, since the protrusion 61 is provided on the middle portion of the baffle 60, that is, a space is formed in front of the air inlet 51, the air staying at the outer circumference of the air inlet 51 is collected in the space of the protrusion 61 and then smoothly enters the air inlet 51, thereby preventing the air bypassing the baffle 60 from generating turbulence at the air inlet 51 and ensuring the intake air volume.

Secondly, the air inlet portion 70 is arranged on the outer side of the air inlet 41, and hair can enter the air inlet 41 after bypassing the air inlet portion 70, so that the difficulty of the hair entering the air inlet 41 is further improved, the hair is effectively prevented from being wound into the fan blades along with the flowing of air, and the usability of the fan blades is ensured.

In addition, the connection between the air inlet portion 70 and the baffle 60 is formed by the engagement between the insertion portion 81 and the inserted portion 82, and the engagement directions of at least one pair of the clip strips and the clip grooves are different, so that mutual resisting acting force can be formed between the insertion portions 81 and the inserted portions 82, and the insertion portions 81 are prevented from being released from the inserted portions 82 due to vibration generated by the operation of the fan blades, thereby improving the stability of installation.

Fig. 7 is a sectional view showing a neck-hung type air blowing device according to a second embodiment of the present invention. Fig. 8 is a sectional view showing a neck-hung type air blowing device according to a second embodiment of the present invention. In the second embodiment, unlike the first embodiment, the diameter of the baffle 60 is smaller than that of the intake vent 41, that is, the baffle 60 does not completely cover the intake vent 41. In addition, in the vertical direction of the baffle 60, at least a portion of the air inlet portion 70 covers a gap between the baffle 60 and the air inlet 41, that is, a portion where the baffle 60 and the air inlet 41 do not overlap.

In the second embodiment, the diameter of the damper 60 is set smaller than the diameter of the air inlet 41 in order to ensure the air volume and to make the air passage smoother before the air enters the blower unit 50. That is, when viewed from a direction perpendicular to the baffle 60, there is a gap 90 between the edge of the intake vent 41 and the edge of the baffle 60, that is, air can enter from the gap 90 between the edge of the intake vent 41 and the edge of the baffle 60.

In addition, in the present embodiment, the air inlet portion 70 is disposed at the outer side of the air inlet 41, the first air opening 71 is disposed between the air inlet portion 70 and the air inlet 41, and the second air opening 72 is disposed at the middle portion of the air inlet portion 70, so that air can enter through the first air opening 71 and the second air opening 72 of the air inlet portion 70, and thus air volume cannot be reduced due to the air inlet portion disposed at the outer side of the air inlet 41. Since the diameter of the baffle 60 is smaller than that of the air inlet 41, the air entering from the first air inlet 71 can directly enter from the gap 90 between the edge of the air inlet 41 and the edge of the baffle 60 without being guided along the baffle 60, and after contacting the inner wall of the snail shell, the air bypasses the edge of the baffle 60 and then blows towards the air inlet 51, that is, the air can not blow towards the inner wall of the snail shell due to the inclination of the protrusion 61 of the baffle 60, but can directly blow towards the air inlet 51 by bypassing the baffle 60 from the gap. In addition, when the air entering from the second air port 72 contacts the baffle 60 and then is blown toward the edge of the air inlet 51 along the inclination of the protrusion 61, the air merges with the air entering from the first air port 71 at the gap 90 between the edge of the baffle 60 and the edge of the air inlet 41, and then is blown toward the air inlet 51 together with the air entering from the first air port 71. Therefore, the air quantity is increased, and the air circulation is further ensured to be smoother.

In addition, when the air supply part 30 rotates to a state where the air inlet 41 is perpendicular to the horizontal plane, the edge of the air inlet 51 is set lower than the extension line of the connection line H between the same side edge of the air inlet part 70 and the same side edge of the baffle 60, so that hair enters from the gap 90 between the edge of the air inlet 41 and the edge of the baffle 60 after entering from the first air inlet along with air, and cannot directly enter the air inlet 51. Thereby preventing hairs from following the air from entering the air inlet 51 from the gap 90 between the edge of the air inlet 41 and the edge of the baffle 60.

Furthermore, when the air supply part 30 is rotated to a state where the air inlet 41 is parallel to the horizontal plane, a part of the air inlet part 70 is disposed above the gap 90 between the edge of the air inlet 41 and the edge of the baffle 60, that is, the air inlet part 70 covers the gap 90 between the edge of the air inlet 41 and the edge of the baffle 60, when viewed from the direction perpendicular to the baffle 60, so that even if the air supply part 30 is rotated to a state where the air inlet 41 is parallel to the horizontal plane, hairs cannot directly enter the air supply unit 50 from the gap 90 between the edge of the air inlet 41 and the edge of the baffle 60, but are blocked outside the air inlet 41 by the air inlet part, thereby further preventing hairs from following the gap 90 between the edge of the air inlet 41 and the edge of the baffle 60 to enter the air inlet 51.

As described above, not only can the hairs be prevented from being caught in the air supply unit 50 in the direction in which the air inlet 41 is perpendicular to the horizontal plane, but also the hairs can be prevented from being caught in the air supply unit 50 in the direction in which the air inlet 41, which makes it easier for the hairs to enter the housing 40, is parallel to the horizontal plane, that is, the present embodiment realizes that the hairs are difficult to enter the fan blades from the air inlets 51 even if the air supply part 30 is rotated in multiple angles. Therefore, the air volume is increased, the hairs are prevented from being clamped due to the change of the angle, and the usability of the fan blade is further ensured.

Therefore, the utility model provides the hanging neck type air supply device, the baffle is arranged on the inner side of the air inlet to prevent hair entering along with air flow from the air inlet from further entering the air supply unit, the air entering from the air inlet can enter the air supply unit only after bypassing the edge of the baffle through the baffle, and the hair entering the air inlet along with the air flow is blown to the edge of the baffle, so that the hair is prevented from further entering the air supply unit. In addition, the baffle is arranged on the inner side of the air inlet, so that the air inlet amount passing through the air inlet is not influenced. Therefore, the baffle is arranged on the inner side of the air inlet, so that not only can hair be prevented from entering the air supply device to influence the service performance of the hanging neck type air supply device, but also the air inlet amount of the hanging neck type air supply device can be ensured.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
