In an embodiment of the present utility model, referring to fig. 1 to 5, the inner core structure 100 of the blower body includes a mounting bracket 110, a heating assembly 120 and a control assembly 130. The mounting bracket 110 has an airflow passage 111 penetrating in the front-rear direction. The heating assembly 120 is fixedly connected to the front end of the mounting bracket 110. The control assembly 130 comprises a control board 131, a heating component group 132 and a non-heat-resistant component group 134 which are electrically connected with the control board 131, the control board 131 is fixedly connected to the rear end of the mounting bracket 110, the surface of the control board 131 faces the heating assembly 120 to form an air inlet space 140, the air inlet space 140 is communicated with the air flow channel 111, and the control board 131 is spaced from the heating assembly 120; the heat generating component set 132 is fixed on a plate surface of the control board 131 facing the air inlet space 140, and the non-heat resistant component set 134 is fixed on a plate surface of the control board 131 facing away from the air inlet space 140.

In this embodiment, the heating assembly 120 and the control assembly 130 are fixed at the front and rear ends of the mounting bracket 110, and the mounting bracket 110 is fully utilized, so that the whole inner core structure 100 of the blower body is more compact, and the occupied space is small. The mounting bracket 110 may have a variety of structures and shapes, and may be selected and designed according to practical needs, and only needs to be provided with the heating assembly 120 and the control assembly 130, and have the air flow channels 111 penetrating from front to back. The airflow channel 111 on the mounting bracket 110 may be a plurality of airflow holes, or may be an annular channel, an arc channel, or the like, which is not particularly limited herein.

The heating assembly 120 is used to heat the air flow introduced into the blower body. The structure and form of the heating element 120 may be varied, and reference is specifically made to existing designs, which are not described in detail herein. The heating component 120 is fixedly connected to the front end of the mounting bracket 110, and the heating component 120 and the mounting bracket 110 can be fixedly connected by means of screws, bonding, clamping, sleeving and the like. The control board 131 is fixedly connected to the rear end of the mounting bracket 110, and the control board 131 can be fixedly connected to the mounting bracket 110 by means of clamping, scarfing, bonding, screw connection and the like.

The inner core structure 100 of the blower body is embedded in the blower housing 200 of the blower. It will be appreciated that the panel surface of the control panel 131 is spaced from the heating assembly 120 such that the control panel 131 forms an air intake space 140 towards the heating assembly 120, the air intake space 140 then being in communication with the air intake of the blower. Through the air flow channel 111 which is arranged on the mounting bracket 110 and penetrates through the front and back, the air flow can directly flow to the heating component 120 through the mounting bracket 110, so that the wind resistance can be effectively reduced, and the air circulation rate can be increased.

In use, the blower causes air to be introduced from the air inlet and into the air inlet space 140 between the control panel 131 and the heating assembly 120, flows through the air flow channel 111 of the mounting bracket 110 to the heating assembly 120, and is then heated by the heating assembly 120 and blown out from the air outlet of the blower.

The control board 131 is electrically connected with various electronic components, and one part of the electronic components such as a resistor, a triode and the like generate heat after long-term use, but are relatively high-temperature resistant, and the other part of the electronic components such as a capacitor 133 and the like generate less heat when in use, but are not high-temperature resistant. By fixing the heat generating component group 132 to the panel surface of the control board 131 facing the air intake space 140, the heat generating component group 132 is positioned in the air intake space 140 after the control board 131 is fixed to the mounting bracket 110. In this way, the unheated cold air flow can enter the air inlet space 140 to cool and dissipate heat of the heat generating component set 132, and then flows to the heating component 120 through the air flow channel 111, and is blown out from the air outlet after being heated by the heating component 120. The non-heat-resistant component group 134 such as the capacitor 133 is mounted on the board surface of the control board 131 away from the air inlet space 140, the control board 131 can isolate the heating assembly 120, so as to prevent the heat radiation of the heating assembly 120 and the hot air flow from directly acting on the non-heat-resistant component group 134 such as the capacitor 133, and prolong the service life of the non-heat-resistant component group of the control assembly 130.

According to the inner core structure 100 of the blower body part, the front and back through airflow channels 111 are formed in the mounting bracket 110, and the heating component 120 and the control plate 131 are respectively fixed at the front and back ends of the mounting bracket 110, so that the overall structure of the inner core structure 100 of the blower body part is more compact, the occupied space is small, the inner core structure 100 is convenient to be assembled in an integrated and modularized manner, and the assembly efficiency is improved.

By spacing the panel surface of the control panel 131 from the heating element 120, the control panel 131 forms an air inlet space 140 with the air flow channel 111 toward the heating element 120, and the heat generating element group requiring heat dissipation is fixed to the panel surface of the control panel 131 facing the air inlet space 140, and the heat non-resistant element group 134 requiring no heat dissipation but being afraid of high temperature is fixed to the panel surface of the control panel 131 facing away from the air inlet space 140. Thus, the cold air flow entering the air inlet space 140 can be directly blown to the heating component group 132 on the control board 131, so that the heating component group 132 is effectively radiated, and the service life of components is prolonged; the air flow can directly blow the heat of the heating element group 132 to the heating component 120 through the air flow channel 111 on the mounting bracket 110 after taking away the heat, so that the air flow path can be shortened, the wind resistance can be effectively reduced, the air flow rate of the blower can be further improved, and the air quantity and the air speed can be increased.

Meanwhile, by fixing the non-heat-resistant component group 134 with small heat generation and no high temperature resistance on the surface of the control board 131 away from the air inlet space 140, the control board 131 can isolate the hot air flow and the heat radiation of the heating assembly 120, so that the influence of high temperature on the non-heat-resistant component group 134 is reduced. The inner core structure 100 of the blower body part of the utility model reasonably distributes the component groups of the control assembly 130, insulates the capacitor 133 through the control board 131, reduces the influence of high temperature on the non-heat-resistant component groups 134, and effectively dissipates heat of the heating component groups 132, so that the overall service life of the control assembly 130 is prolonged while the whole inner core structure 100 is compact in layout, small in occupied space and few in parts, and further the aging rate of the inner core structure 100 is slowed down, and the product quality and service life are improved.

Further, the non-heat-resistant component group 134 includes a capacitor 133, and the length direction of the capacitor 133 is consistent with the extending direction of the board surface of the control board 131.

In the present embodiment, the non-heat-resistant component group 134 may include, in addition to the capacitor 133, a few high-temperature-resistant sensors, semiconductors, and other electronic components. The capacitor 133 generates heat less when using, but does not resist high temperature, and the whole volume of the capacitor 133 is great, through making the capacitor 133 be fixed in the face that the control panel 131 deviates from the air inlet space 140, can effectively insulate against heat the capacitor 133 on the one hand, promote capacitor 133 life, on the other hand avoid the capacitor 133 to locate in the air inlet space 140 and cause the hindrance to the gas flow, in other words, can effectively reduce the windage, promote the gas circulation rate of hair-dryer, increase amount of wind and wind speed. It can be appreciated that the length direction of the capacitor 133 is consistent with the extending direction of the board surface of the control board 131, and the capacitor 133 may be parallel to the board surface or may be disposed at an included angle of not more than 5 degrees. Through making the length direction of electric capacity 133 unanimous with the face extending direction of control panel 131, can make full use of control panel 131 face extending direction's space reduces the inner core structure 100 at the epaxial size of control panel 131, and then can make whole inner core structure 100 compacter, is favorable to the miniaturization and the portability of hair-dryer volume.

In this embodiment, the ion generating module 150 may be a negative ion module, a plasma module, a water ion module, or the like, and different types of ion generating modules 150 may be selected according to actual requirements. It is understood that the high temperature may affect the service life of the negative ion generating module 150 and the plasma generating module 150 and the ion release amount. Through making ion generation module 150 also install in the control panel 131 one side that deviates from air inlet space 140, the accessible control panel 131 carries out effective thermal-insulated to ion generation module 150, avoids high temperature to influence ion generation module 150 to can promote ion generation module 150's life, guarantee ion generation module 150's ion release volume.

In an embodiment, referring to fig. 2 to 5, the mounting bracket 110 includes an annular surrounding wall 112 extending along a circumferential direction of the control plate 131, and the control plate 131 is fixed to a rear end of the annular surrounding wall 112; the annular surrounding wall 112 and the control board 131 enclose to form the air inlet space 140, and the annular surrounding wall 112 has an air inlet notch 113 communicated with the air inlet space 140.

In the present embodiment, by making the mounting bracket 110 include the annular surrounding wall 112, and the annular surrounding wall 112 encloses the control panel 131 to form the air intake space 140, the annular surrounding wall 112 can effectively rectify the air flow. The annular surrounding wall 112 is provided with the air inlet gap 113, so, when the whole inner core structure 100 is installed in the air duct shell 200 of the air blowing machine body, cold air flow in the handle enters the air inlet space 140 from the air inlet gap 113 along the radial direction of the annular surrounding wall 112, can be directly blown to the heating element group 132 of the control panel 131, and the air flow can flow along the circumferential direction of the annular surrounding wall 112, so that the heat of the heating element group 132 on the control panel 131 can be better and more effectively taken away, and the heat dissipation efficiency and effect are improved.

The cross-section of the annular enclosure wall 112 may be circular, oval, profiled, etc. Specifically, the control plate 131 is circularly disposed, and the cross section of the annular surrounding wall 112 is circularly disposed. In this way, the air flow can flow smoothly along the inner periphery of the annular surrounding wall 112, so that the wind resistance can be effectively reduced, the wind speed can be increased, and abnormal sound and noise can be avoided.

In an embodiment, as shown in fig. 3, 5, 7 and 8, an annular groove 114 is formed at the connection between the rear end surface and the inner wall surface of the annular surrounding wall 112, and the control board 131 is adapted to be embedded in the annular groove 114. By providing the annular caulking groove 114 at the rear end of the annular surrounding wall 112, the control board 131 is embedded in the annular caulking groove 114, so that the control board 131 can completely cover the rear end opening of the annular surrounding wall 112, and the overall structure is more compact while the control board 131 is ensured to effectively isolate the heating component 120.

In one embodiment, as shown in fig. 3 to 5, the mounting bracket 110 further includes a middle mounting stage 116 connected to the inner side of the annular surrounding wall 112, the heating element 120 is fixedly connected to a side of the middle mounting stage 116 facing away from the control board 131, and the air flow channel 111 is formed between the annular surrounding wall 112 and the middle mounting stage 116.

In this embodiment, the middle mounting stand 116 may be circular, rectangular, or shaped, and the specific shape thereof may be selected and designed according to actual requirements. To reduce windage, the center mount 116 is optionally circular in cross-section. The middle mounting table 116 and the annular surrounding wall 112 can be fixedly connected through a connecting rod, a connecting plate and the like. The outer peripheral wall of the center mount 116 is spaced from the inner peripheral wall of the annular surrounding wall 112 to form an annular air flow passage 111. The heating assembly 120 and the middle mounting table 116 can be fixedly connected by means of screws, clamping and the like. By having the heating assembly 120 fixedly attached to the mid-mount 116, a secure connection of the heating assembly 120 to the mounting bracket 110 is ensured. And locate the one side that the mid-mounting platform 116 deviates from the control panel 131 with the frame 121 that generates heat, then this mid-mounting platform 116 still can play certain thermal-insulated effect for the heating element is more to be kept away from the heating element group 132 on the control panel 131, in order to reduce the influence of the heat radiation of heating element to the heating element group 132. The annular air flow channel 111 is formed by enclosing the middle mounting table 116 and the annular enclosing wall 112, so that the contact time between the air flow entering the air inlet space 140 and the heating component group 132 on the control board 131 is longer, and the heat dissipation effect on the heating component group 132 is better.

Specifically, the mid-mount 116 is located at a side end of the annular enclosure wall 112 remote from the control panel 131. That is, the center mount 116 is located at the rearward side of the center of the annular enclosure wall 112. In this way, the middle mounting table 116 and the heating assembly 120 mounted thereon are further away from the control board 131, so as to reduce the influence of the heat radiation of the heating assembly 120 on the heating components on the control board 131. Meanwhile, the air flow space formed between the middle mounting table 116 and the control plate 131 is larger, so that the wind resistance can be reduced, the air flow rate can be improved, and the overall wind speed and the overall wind quantity can be improved.

In an embodiment, referring again to fig. 3 to 5, the mounting bracket 110 further includes a plurality of connecting arms 117, one ends of the connecting arms 117 are connected to the middle mounting table 116, and the other ends are connected to the inner wall surface of the annular surrounding wall 112; a plurality of connecting arms 117 are arranged at intervals along the circumferential direction of the annular surrounding wall 112, and the air flow channel 111 is formed between two adjacent connecting arms 117; the control board 131 is fixedly connected to a plurality of the connection arms 117.

In the present embodiment, the shape and structure of the connection arm 117 may be various, and is not particularly limited herein. The number of connecting arms 117 may be selected and designed according to the dimensions of the central mounting stage 116 and the annular surrounding wall 112, and is not particularly limited herein. To improve structural strength, optionally, the middle mounting stage 116, the plurality of connecting arms 117, and the annular surrounding wall 112 are integrally formed. Since the middle mounting table 116 is mainly used for fixing the heating component 120, the middle mounting table 116 is connected to the annular surrounding wall 112 through the plurality of connecting arms 117, so that the connection stability of the middle mounting table 116 and the annular surrounding wall 112 can be ensured, and the supporting strength of the middle mounting table 116 can be improved. Because of the small thickness of the annular enclosure wall 112, it is inconvenient to process the connection structure fixed to the control board 131. By making the control board 131 fixedly connected to the plurality of connection arms 117, the control board 131 can be fixed by fully utilizing the connection arms 117, the structure of the mounting bracket 110 is simplified, and the connection stability of the whole mounting bracket 110 and the control board 131 is improved. The control board 131 and the connecting arm 117 can be fixedly connected by a screw, a clamping connection or the like.

In order to avoid that the connecting arms 117 block the flow of air in the circumferential direction of the annular enclosure wall 112, optionally, the width of the connecting arms 117 at the connection with the annular enclosure wall 112 is smaller than the width of the annular enclosure wall 112 in the axial direction of the annular enclosure wall 112. In this way, the air flow flowing into the annular enclosure wall 112 can flow along the inner peripheral wall of the annular enclosure wall 112.

The mounting post 118 may be embodied as a threaded post and the connector may be embodied as a screw. By providing the mounting posts 118 on the connection arms 117 such that the screws pass through the control plate 131 to be screwed with the threaded holes on the connection posts, the connection strength between the control plate 131 and the entire mounting bracket 110 can be further improved.

In this embodiment, the heating element (not shown) may be a heating structure such as a heating wire or a heating sheet. The heat generating shelf 121 provides mounting for a heating element (not shown). The heating frame 121 and the middle mounting table 116 can be fixedly connected by threads, screws, buckles and the like. By arranging the heating element (not shown) corresponding to the air flow channel 111, after the air flow in the air inlet channel 21 effectively dissipates heat of the heating element on the control board 131, the air can be directly blown from the air inlet channel 21 to the heating element (not shown), the air flow path can be shortened, the wind resistance can be effectively reduced, the air flow rate of the blower can be improved, and the air quantity and the air speed can be increased.

Such that sleeve 124 interfaces with annular enclosure wall 112 in a fore-aft direction, i.e., the inner diameter of sleeve 124 is substantially the same as the inner diameter of annular enclosure wall 112. In this way, the air flowing along the annular surrounding wall 112 can directly flow along the inner wall surface of the heat insulation sleeve 124 to blow against the heating element (not shown), so that the air outlet of the whole inner core structure 100 is smoother and more unobstructed.

The plurality of substrates 125 are inserted and connected to the insertion boss 123 of the heating frame 121, so that the assembly of the heating assembly 120 is more convenient. Since the annular air flow passage 111 is formed between the outer peripheral wall of the center mounting stage 116 and the inner peripheral wall of the annular surrounding wall 112, that is, the air flow flowing from the air intake space 140 to the air flow passage 111 flows along the inner peripheral wall of the annular surrounding wall 112 and the outer peripheral wall of the center mounting stage 116. By making the peripheral wall of the middle mounting table 116 lower than or flush with the inner side wall of the substrate 125 facing the mounting cylinder 122, the blocking of the middle mounting table 116 to the airflow flowing toward the heating element (not shown) can be reduced, so that the airflow in the airflow channel 111 can be blown toward the heating element (not shown), and the overall heating effect is improved.
