DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] The present embodiment provides a ceramic component for use in an air supply device, including a ceramic substrate 100 and a ventilation hole 110 provided on the ceramic substrate 100. The ceramic substrate 100 includes a plurality of ceramic bodies, and the plurality of ceramic bodies are detachably spliced.

[0030] This embodiment also provides a hair dryer, such as Figure 1 and Figure 2As shown, it includes a shell 200 and the above-mentioned ceramic component, and an air duct 210 is formed in the shell 200. One end of the air duct 210 is an air inlet 220, and the other end is an air outlet 230; the ceramic component is installed in the air duct 210, and at least one ceramic body of the ceramic component is detachably fixed to the remaining ceramic bodies or the shell 200.

[0031] The ceramic parts and hair dryer provided in this embodiment, wherein the ceramic parts as health-care ceramics include a plurality of ceramic bodies as a spliced ​​body, each of which can be used as a matrix for carrying nutritional health-care media, or the ceramic bodies themselves can release health-care media such as far infrared rays or negative ions; wherein the hair dryer, as one of the air supply devices, includes a shell 200 with an air duct 210 formed inside and the above-mentioned ceramic parts as health-care ceramics.

[0032] When the ceramic component is used in a hair dryer, the ceramic base 100 of the ceramic component is blocked in the air duct 210. During the operation of the hair dryer, external air flows into the air duct 210 through the air inlet 220 of the air duct 210, flows through the ceramic base 100 and is blown out through the air outlet 230. The health care medium released outward by the ceramic base 100 is blown toward the user's head through the air outlet 230 along with the air flow, thereby playing a health care role for the user's head or the user's hair. Among them, the ceramic matrix 100 of the ceramic piece is formed by splicing multiple ceramic bodies. The multiple ceramic bodies can each be used as a matrix of the same type, different types or multiple types of health-care media as an independent spliced ​​body. For example, multiple ceramic bodies can be used as matrices of one or more health-care media such as far infrared rays, negative ions, collagen matrix and vitamin C, and users can select ceramic bodies carrying different health-care media to splice to form the ceramic matrix 100 according to actual needs. During the operation of the hair dryer, the multiple ceramic bodies can release the corresponding multiple health-care media outward with the airflow, and the multiple health-care media can play different health-care roles on the user's head or hair, thereby improving the health-care functionality of the ceramic piece and the hair dryer; of course, users can also select multiple ceramic bodies carrying the same health-care medium to splice to form the ceramic matrix 100 according to needs. During the operation of the hair dryer, the concentration of the same health-care medium released outward by the multiple ceramic bodies is relatively large, which correspondingly enhances the specific health-care effects of the ceramic piece and the hair dryer on the user's head or hair.

[0033] In addition, when the ceramic substrate 100 is loaded into the air duct 210, at least one of the multiple ceramic bodies of the ceramic substrate 100 is fixed to the remaining ceramic bodies or the shell 200 in a detachable manner to be fixed in the air duct 210, and this type of ceramic body is defined as a replaceable ceramic body. After a period of use, the user can remove this type of replaceable ceramic body from the remaining ceramic bodies or the shell 200 and replace it with a ceramic body carrying the target health-care medium; or the nutritional health-care medium carried on the replaceable ceramic body is gradually consumed with the use time, and the user can replace it with a new nutritional health-care medium ceramic body. The above-mentioned setting can realize the replacement of the type of health-care medium of the ceramic part without replacing the entire hair dryer, and correspondingly realize the replacement of different health-care performances of the hair dryer, thereby improving the diversification and reusability of the health-care effect of the hair dryer; in addition, it can also realize the repeated replenishment of the nutritional health-care medium, correspondingly reducing the user's replacement cost and the waste of resources caused thereby.

[0034] It should be noted that the above-mentioned "multiple ceramic bodies are detachably spliced" means that there is no fixed connection between the multiple ceramic bodies, or there is a detachable fixed connection between two adjacent ceramic bodies, and the multiple ceramic bodies can be spliced ​​into a ceramic matrix 100 of a specific shape; wherein the number of ceramic bodies can be two, three, four, etc.

[0035] Specifically, Figure 2 As shown, a bracket 310 can be arranged in the air duct 210 of the hair dryer, a motor 320 is installed on the bracket 310, a fan 330 is installed at the driving end of the motor 320, and the fan 330 is located between the air inlet 220 and the ceramic part. When in use, the motor 320 drives the fan 330 to rotate, and the fan 330 drives the external air to flow into the air duct 210 through the air inlet 220, and then flows through the ceramic part and then flows out through the air outlet 230, thereby realizing the carrying of the health care medium of the ceramic part. Preferably, as Figure 1 and Figure 2 As shown, a handle 400 may be provided at the bottom of the hair dryer housing 200 to facilitate the user to hold the hair dryer, thereby correspondingly improving the convenience of using the hair dryer.

[0036] Of course, in other embodiments, in addition to the above-mentioned hair dryer, the air supply device can also use a heater, etc., and the ceramic component can be installed in the air duct 210 of the heater. The ceramic component can be used as a matrix for releasing far infrared rays, negative ions or fragrances and other health media. When the heater is running, the ceramic component can release far infrared rays, negative ions or fragrances to the external space along with the air flow, thereby having the effect of antibacterial and antibacterial effect on the external space and improving human immunity.

[0037] Optionally, at least two ceramic bodies in the ceramic matrix 100 are detachably fixed. When the ceramic matrix 100 is installed in the air duct 210, a single ceramic body is connected to at least the inner wall of the air duct 210 and one of the remaining ceramic bodies. Compared with multiple ceramic bodies that are all spliced ​​movably, and multiple ceramic bodies need to be connected to the inner wall of the air duct 210, the present application sets at least two ceramic bodies to be detachably fixed. On the one hand, the integrity of the ceramic matrix 100 is higher, and the convenience and position accuracy of the ceramic matrix 100 in installing the air duct 210 are higher; on the other hand, when installing the ceramic matrix 100, at least one of the two detachably fixed ceramic bodies does not need to be connected to the inner wall of the air duct 210, so the convenience of installing the ceramic matrix 100 is higher, and the ceramic body can be replaced as a replaceable ceramic body, and during the replacement process, it only needs to be disassembled and assembled with another ceramic body, and the replacement convenience is higher. Specifically, the two ceramic bodies can be detachably fixedly connected by means of snap connection, plug-in connection, connectors, etc.

[0038] Specifically, Figure 4 As shown, the ceramic body can be two pieces, the two ceramic bodies are respectively a first ceramic body 120 and a second ceramic body 130, the first ceramic body 120 is annular, and the second ceramic body 130 is embedded in the annular space 124 of the first ceramic body 120. This is a specific form of the ceramic substrate 100. On the one hand, the first ceramic body 120 is arranged around the second ceramic body 130, and the annular space 124 of the first ceramic body 120 can limit the position of the second ceramic body 130, thereby improving the overall compactness of the entire ceramic substrate 100 and the relative position accuracy of the first ceramic body 120 and the second ceramic body 130, and correspondingly improving the convenience and position accuracy of the ceramic substrate 100 when it is installed in the air duct 210. On the other hand, when the second ceramic body 130 and the first ceramic body 120 are detachably fixed, when the ceramic base 100 is loaded into the air duct 210, only the first ceramic body 120 can be connected to the inner wall of the air duct 210, and the second ceramic body 130 is only detachably fixed to the first ceramic body 120, so that the ceramic base 100 is more convenient to load into the air duct 210; and the second ceramic body 130 can be used as a replaceable ceramic body, and only needs to be relative to the first ceramic body 120. The second ceramic body 130 can be replaced by simply disassembling it, and the replacement is very convenient. In addition, the second ceramic body 130 is detachably fixed to the inner ring space 124 of the first ceramic body 120, that is, the first ceramic body 120 is separated between the second ceramic body 130 and the inner wall of the air duct 210. The disassembly and assembly process of the second ceramic body 130 is less interfered by the inner wall of the air duct 210, and the second ceramic body 130 can be directly removed from the air outlet 230, thereby further improving the convenience of replacing the second ceramic body 130.

[0039] Of course, in other embodiments, the second ceramic body 130 can also be movably embedded in the inner ring space 124 of the first ceramic body 120, and the first ceramic body 120 and the second ceramic body 130 are respectively connected to the inner wall of the air duct 210, and at least one of them is detachably fixed to the inner wall of the air duct 210.

[0040] Optionally, the outer shape and inner shape of the first ceramic body 120 can be square, triangular, circular or other irregular shapes, and it is only necessary to ensure that the first ceramic body 120 is a continuous ring; the shape of the second ceramic body 130 is consistent with the inner shape of the first ceramic body 120. Specifically, the first ceramic body 120 can be a circular ring, then the outer shape and inner shape of the first ceramic body 120 are both circular, and the second ceramic body 130 is also circular; on the one hand, there is no corner in the inner space 124, and the second ceramic body 130 can be embedded at any angle when it is installed in the inner space 124, so the installation convenience of the second ceramic body 130 is higher; on the other hand, the outer shape of the first ceramic body 120 determines the shape of the entire ceramic matrix 100, and the circular ceramic matrix 100 is consistent with the cross-sectional shape of the air duct 210 of the hair dryer, and the installation of the ceramic matrix 100 into the air duct 210 is less affected by the circumferential installation angle, thereby improving the convenience of the ceramic matrix 100 into the air duct 210.

[0041] Preferably, the ceramic component can be consistent with the radial cross-section of the air duct 210, and the ceramic component is matched and blocked in the air duct 210, and the air inlet 220 and the air outlet 230 of the air duct 210 are connected through the ventilation holes 110 of the ceramic component. The airflow flowing into the air duct 210 through the air inlet 220 must all flow through the ventilation holes 110 before flowing out from the air outlet 230. In the process of all the airflow flowing through the ceramic component, the carrying capacity of the health-care medium released therefrom or the nutritional health-care medium it carries is stronger. Accordingly, the concentration of the health-care medium entrained in the airflow blown out by the hair dryer is higher, and the health-care effect for the user is better.

[0042] Specifically, in this embodiment, Figure 2 and Figure 3 As shown, the shell 200 of the hair dryer may include an insulating tube 240 arranged in the inner layer, and a mounting ring 241 is provided at one end of the insulating tube 240 facing the air outlet 230, and the mounting ring 241 matches the first ceramic body 120; the inner wall of the mounting ring 241 is provided with a plurality of ribs 242, and the plurality of ribs 242 all extend along the axial direction of the mounting ring 241, and the plurality of ribs 242 are arranged at intervals along the circumference of the air duct 210; the ceramic component is tightly inserted into the mounting ring 241 under the squeezing action of the ribs 242, thereby realizing the detachable fixing of the first ceramic body 120 and the shell 200, and the ceramic component is fixedly installed in the air duct 210 accordingly.

[0043] Optionally, in this embodiment, if Figure 6As shown, the first ceramic body 120 may include a first annular honeycomb body 121, the outer wall of the first honeycomb body 121 is surrounded by a first outer ring 122, and the inner wall of the first honeycomb body 121 is surrounded by an inner ring 123; the second ceramic body 130 includes a second honeycomb body 131, and the outer wall of the second honeycomb body 131 is surrounded by a second outer ring 132. Firstly, the first ceramic body 120 and the second ceramic body 130 respectively use the first honeycomb body 121 and the second honeycomb body 131 as the main body of the matrix, and the specific surface area of ​​the honeycomb body is large, and the corresponding ability to carry the nutritional health medium is strong, and the ability to release the health medium to the outside is also strong. The honeycomb holes serve as ventilation holes 110, and the concentration of the health medium entrained in the process of the airflow flowing through the honeycomb body is higher, and the corresponding health effect on the user is better. Secondly, the first outer ring 122 and the inner ring 123 can respectively reinforce the outer ring and the inner ring of the first honeycomb body 121 to improve the overall strength of the first ceramic body 120, and correspondingly improve the stability of the first ceramic body 120 when loaded into the air duct 210, and reduce the occurrence of the first ceramic body 120 being easily damaged by bumps during processing, transportation and use; similarly, the second outer ring 132 can reinforce the circumferential outer wall of the second honeycomb body 131 to improve the overall strength of the second ceramic body 130, and correspondingly improve the stability of the second ceramic body 130 when loaded into the first ceramic body 120, and reduce the occurrence of the second ceramic body 130 being easily damaged by bumps during processing, transportation and use.

[0044] Of course, in other embodiments, the first outer ring 122 may be provided only on the outer wall of the first honeycomb body 121, or the inner ring 123 may be provided only on the inner wall of the first honeycomb body 121; and only one of the first ceramic body 120 and the second ceramic body 130 may adopt the above corresponding form.

[0045] In this embodiment, Figure 5 and Figure 6 As shown, a clamping platform 125 can be provided on the inner wall of the ring of the first ceramic body 120, and a first limiting platform 133 can be provided on the outer wall of the second ceramic body 130. The first limiting platform 133 includes a first limiting arm 133a and a second limiting arm 133b connected to the first end of the first limiting arm 133a. The first limiting arm 133a extends along the axial direction of the second ceramic body 130, and the second limiting arm 133b extends along the circumferential direction of the second ceramic body 130. A limiting groove 133e is formed between the first limiting arm 133a and the second limiting arm 133b, and the clamping platform 125 is clamped in the limiting groove 133e; a second limiting platform 126 is provided on the inner wall of the ring of the first ceramic body 120, and along the axial direction of the first ceramic body 120, the second limiting platform 126 and the first limiting arm 133a are respectively located on both sides of the second limiting arm 133b, and the second limiting platform 126 abuts against the end face of the corresponding side of the second ceramic body 130.

[0046] This is a specific form of detachable fixing of the first ceramic body 120 and the second ceramic body 130. When connecting, align the second ceramic body 130 from the port close to the clamping platform 125 and insert it into the annular space 124 of the first ceramic body 120. Before insertion, it is necessary to ensure that the first limiting platform 133 and the clamping platform 125 are at different positions in the circumferential direction of the annular space 124, and the second limiting arm 133b of the first limiting platform 133 is facing the annular space 124; when the end face of the second ceramic body 130 abuts against the second limiting platform 126, the second ceramic body 130 can no longer continue to be inserted into the annular space 124, and the limiting groove 133e surrounded by the first limiting arm 133a and the second limiting arm 133b, and the limiting groove 133e and the limiting groove 133e are aligned. The opening on the side opposite to the first limiting arm 133a is a notch, and then the second ceramic body 130 is rotated toward the clamping platform 125, and the clamping platform 125 is clamped into the limiting groove 133e through the notch, wherein the clamping platform 125 abuts against the first limiting arm 133a to limit the circumferential position of the second ceramic body 130 relative to the first ceramic body 120, the clamping platform 125 abuts against the second limiting arm 133b to limit the first axial position of the second ceramic body 130 relative to the first ceramic body 120, and the second limiting platform 126 abuts against the end surface of the second ceramic body 130 to limit the second axial position of the second ceramic body 130 relative to the first ceramic body 120, thereby realizing the detachable fixing of the second ceramic body 130 and the first ceramic body 120. When the second ceramic body 130 needs to be disassembled, the second ceramic body 130 can be rotated in the opposite direction and pulled out. Preferably, there can be two clamping platforms 125 and two first limit platforms 133, and the two clamping platforms 125 and the two first limit platforms 133 are arranged opposite to each other along the circumferential direction. Then, when the second ceramic body 130 is installed, the two first limit platforms 133 can be clamped with the two clamping platforms 125 one by one, and the first ceramic body 120 and the second ceramic body 130 are connected and limited at two circumferentially opposite positions, thereby improving the clamping stability and firmness of the two. Similarly, there can be two second limit platforms 126, or the second limit platform 126 is an annular limit platform.

[0047] In addition to the second limiting platform 126 mentioned above, the inner wall of the ring of the first ceramic body 120 can also adopt the following form: a third limiting arm is connected to the second end of the first limiting arm 133a, and the third limiting arm extends along the circumference of the second ceramic body 130, and the second limiting arm 133b and the third limiting arm are located on the same side of the first limiting arm 133a. The first limiting arm 133a, the second limiting arm 133b and the third limiting arm together form a limiting groove 133e with an opening on one side. When connecting, the second ceramic body 130 is inserted into the inner ring space 124 of the first ceramic body 120, and when the clamping platform 125 is at the same height as the opening on one side of the limiting groove 133e, the first ceramic body 120 and the second ceramic body 130 are relatively rotated, so that the clamping platform 125 is clamped into the limiting groove 133e from the opening, wherein the first limiting arm 133a can limit the first ceramic body The second limiting arm 133b and the third limiting arm are respectively located on both sides of the clamping platform 125, which can limit the axial relative position of the first ceramic body 120 and the second ceramic body 130, thereby realizing the detachable fixing of the first ceramic body 120 and the second ceramic body 130; when disassembling, the first ceramic body 120 or the second ceramic body 130 is rotated in the opposite direction so that the clamping platform 125 is disengaged from the limiting groove 133e, and then the second ceramic body 130 is pulled out.

[0048] Specifically, in this embodiment, Figure 5 and Figure 6As shown, the inner wall surface of the limiting groove 133e and the corresponding groove of the second limiting arm 133b is the guide wall surface 133c, and the guide wall surface 133c extends along the circumference of the second ceramic body 130 and in the direction away from the first end of the first limiting arm 133a; the wall surface of the clamping platform 125 facing the guide wall surface 133c is the clamping wall surface 125a, and the clamping wall surface 125a matches the guide wall surface 133c. The guide wall surface 133c of the limiting groove 133e is an inclined surface, and the groove width of the limiting groove 133e gradually decreases (when the second limiting body is set, the second limiting body and the second limiting arm 133b jointly determine the groove width of the limiting groove 133e; when the third limiting arm is set, the third limiting arm and the second limiting arm 133b jointly determine the groove width of the limiting groove 133e), and the notch of the limiting groove 133e is located at the end with a larger groove width; the clamping wall surface 125a of the clamping platform 125 is also an inclined surface, and the thickness of the clamping platform 125 also gradually decreases. When connected, the clamping platform 1 The end with a smaller thickness of 25 is first inserted into the notch of the limiting groove 133e, and then as the first ceramic body 120 and the second ceramic body 130 rotate relative to each other, the guide wall surface 133c guides the clamping platform 125 through the clamping wall surface 125a until the clamping platform 125 is matched and clamped into the limiting groove 133e, thereby improving the convenience of inserting the clamping platform 125 into the limiting groove 133e and the firmness of the clamping between the clamping platform 125 and the limiting groove 133e, and correspondingly improving the convenience and firmness of the clamping between the first ceramic body 120 and the second ceramic body 130.

[0049] In this embodiment, a locking boss 133d may be provided on one of the guide wall surface 133c and the engaging wall surface 125a, and a locking groove 125b matching the locking boss 133d may be provided on the other. Figure 5 and Figure 6As shown, taking the locking boss 133d provided on the guide wall surface 133c and the locking groove 125b provided on the clamping wall surface 125a as an example, during the process of the clamping platform 125 being clamped into the limiting groove 133e, when the clamping platform 125 contacts the locking boss 133d, the first ceramic body 120 and the second ceramic body 130 continue to rotate relative to each other, and the locking boss 133d contacts the clamping wall surface 125a tightly, until the locking groove 125b on the clamping wall surface 125a rotates to the position of the locking boss 133d, and the locking boss 133d is clamped into the locking groove 125b. , thereby locking the circumferential rotation of the clamping platform 125 and the first limiting platform 133, reducing the occurrence of the clamping platform 125 being loosened from the limiting groove 133e due to the circumferential rotation of the clamping platform 125 relative to the first limiting platform 133, and correspondingly further improving the clamping firmness of the first ceramic body 120 and the second ceramic body 130; when it is necessary to disassemble the second ceramic body 130, the first ceramic body 120 and the second ceramic body 130 are rotated in the opposite direction with force, so that the locking boss 133d is disengaged from the locking groove 125b until the clamping platform 125 rotates out of the limiting groove 133e. Preferably, along the extension direction of the guide wall surface 133c, the locking surface of the locking boss 133d can be an outwardly convex arc surface, and both ends of the locking surface are smoothly connected to the guide wall surface 133c, so as to reduce the occurrence of the clamping platform 125 being stuck at the locking boss 133d and unable to continue to rotate.

[0050] Optionally, in this embodiment, if Figure 5 As shown, one end of the second limiting arm 133b away from the first limiting arm 133a may also be connected to the fourth limiting arm 133f, and the first limiting arm 133a and the fourth limiting arm 133f are respectively located on both sides of the second limiting arm 133b. When the second ceramic body 130 is inserted into the inner ring space 124 of the first ceramic body 120, when the depth of the clamping platform 125 is consistent with the depth of the fourth limiting arm 133f, the second ceramic body 130 is rotated, and the clamping platform 125 abuts against the fourth limiting arm 133f. The user can circumferentially adjust the insertion and extension of the second ceramic body 130 so that the clamping platform 125 slides along the fourth limiting arm 133f to the notch of the limiting groove 133e and slides into the limiting groove 133e. The setting of the fourth limiting arm 133f can reduce the restriction of the limiting groove 133e on the initial insertion depth of the second ceramic body 130 into the inner ring space 124, thereby further improving the convenience of connecting the first ceramic body 120 and the second ceramic body 130.
