The utility model provides a tail cover structure of a blower.

In an embodiment of the present utility model, referring to fig. 1 to 4, 8 and 9, the tail cover structure 100 of the blower is configured to be mounted at the rear end of the blower housing 200, wherein the tail cover structure 100 of the blower includes a light guide 110 and a light source 150. The light guide base 110 includes an embedded light shielding surrounding wall 112 and a light guide member 131 connected to the rear end of the embedded light shielding surrounding wall 112, the embedded light shielding surrounding wall 112 is used for being embedded in the rear end opening of the wind turbine shell 200, the embedded light shielding surrounding wall 112 is surrounded to form a light source mounting cavity 113, and the light guide member 131 is at least partially exposed out of the embedded light shielding surrounding wall 112; the light guide member 131 is provided with a light guide groove 132 communicating with the light source installation cavity 113. The light source 150 is mounted in the light source mounting cavity 113 and/or the light guide groove 132, and the light emitting member 151 of the light source 150 faces the light guide member 131, so that the light is guided out of the wind turbine housing 200 through the light guide member 131.

In this embodiment, for convenience of explanation, the description direction is referred to the orientation of the user when using the blower. The fore-aft direction is the axial direction of the cartridge housing 200. The front end refers to the end of the air duct housing 200 that is directed toward the user's air outlet, and the rear end refers to the end of the air duct housing 200 that is directed away from the user. The light guide 110 is integrally used for mounting the light source 150 and guiding out light. The embedded light shielding surrounding wall 112 is used for being embedded in the rear end opening 210 of the blower housing 200 of the blower, and specifically, a fastening hole, a fastening hook and other structures can be further arranged on the embedded light shielding surrounding wall 112 to fixedly connect the embedded light shielding surrounding wall 112 and the blower housing 200. Of course, the embedded shadow enclosure wall 112 may also be made to have an interference fit with the air duct housing 200 to achieve a secure installation of the entire tail cap structure 100 within the air duct housing 200. The embedded light shielding wall 112 may be made of light shielding plastic or other light shielding materials, and the embedded light shielding wall 112 may be coated with a light shielding coating layer to form a light shielding effect. The light guide member 131 may be made of light guide material such as acryl or polycarbonate. The embedded light shielding surrounding wall 112 and the light guide member 131 may be two independently formed components, or may be integrally formed components through processes such as two-shot molding, and the like, which are not particularly limited herein.

It will be appreciated that the embedded light-shielding enclosure wall 112 is generally annular in shape. The cross-sectional shape of the embedded shadow enclosure wall 112 is adapted to the cross-sectional shape of the wind turbine housing 200. Optionally, the cross-sectional shape of the embedded light-shielding enclosure wall 112 is circular for aesthetic and ease of assembly. The embedded light shielding surrounding wall 112 encloses to form a light source installation cavity 113, and the light guide groove 132 of the light guide member 131 is communicated with the light source installation cavity 113, so that the light source 150 can be only installed in the light source installation cavity 113 or the light guide groove 132, and can also be installed at the joint of the light source installation cavity 113 and the light guide groove 132. The light source 150 may be a light board, where the light board includes a PCB board and a light emitting member 151 mounted on the PCB, and the light emitting member 151 may be a plurality of LED light beads. So that the light emitting member 151 of the light source 150 faces the light guiding member 131, and the light can be transmitted out of the light guiding member 131, so as to achieve the light emitting effect of the tail cap structure 100.

The light guide member 131 is at least partially exposed to the embedded light shielding surrounding wall 112, so that the end surface of the light guide member 131 is exposed to the embedded light shielding surrounding wall 112, or a portion of the peripheral side wall of the light guide member 131 is exposed to the embedded light shielding surrounding wall 112. And the light guide member 131 is at least partially exposed out of the embedded light shielding surrounding wall 112, when the tail cover structure 100 is mounted at the rear end of the air duct shell 200, the light guide member 131 is also exposed out of the rear end opening 210 of the air duct shell 200. Thus, the light of the light source 150 disposed in the light guide 110 can be transmitted out of the blower through the light guide 131.

The tail cover structure 100 of the blower of the present utility model makes the embedded light shielding surrounding wall 112 of the light guiding seat 110 made of light shielding material, and the embedded light shielding surrounding wall 112 is used for being embedded at the rear end of the air cylinder shell 200, thus, the tail cover component is integrally embedded at the rear end of the air cylinder shell 200, and the splice seam between the tail cover structure 100 and the side wall of the air cylinder shell 200 can be eliminated, and meanwhile, the light of the light source 150 installed in the light guiding seat 110 is prevented from being transmitted to the air cylinder shell 200 by the embedded light shielding surrounding wall 112, thereby preventing the air cylinder shell 200 from transmitting light, and improving the product quality and the light emitting effect. And the embedded shading surrounding wall 112 is made of shading materials, compared with a mode of adding shading materials in the air cylinder shell 200 to avoid light transmission, the material property of the air cylinder shell 200 is prevented from becoming fragile and being easy to break, and the use reliability of products is improved.

In one embodiment, as shown in fig. 3 to 6 and fig. 9 to 11, the light guide base 110 includes a light shielding member 111 and a light guide member 130 connected to each other, the light shielding member 111 is made of a light shielding material, and the light guide member 130 is made of a light transmitting material; the light shielding member 111 includes the embedded light shielding surrounding wall 112; the light guide 130 includes a light-transmitting main body 133, and a light guide groove 132 is formed on the light-transmitting main body 133; the embedded light shielding surrounding wall 112 surrounds and is connected to the light transmitting body 133.

In the present embodiment, the light shielding member 111 is integrally made of a light shielding material, and the light guiding member 130 is integrally made of a light transmitting material. The light shielding member 111 and the light guiding member 130 may be integrally injection-molded and connected by means of two-shot injection molding, or may be fixedly connected by means of clamping, scarfing, welding, etc. By dividing the light guide seat 110 into two parts, namely the light shielding part 111 and the light guiding part 130, the light shielding part 111 and the light guiding part 130 are made of different materials respectively, and compared with the light guide part 130 which is made of a light-transmitting material as a whole, the light shielding effect of the whole embedded light shielding surrounding wall 112 can be improved by only arranging the light shielding coating on the periphery of the embedded light shielding surrounding wall 112, and light is effectively prevented from being transmitted out of the wind cylinder shell 200. The light-transmitting body 133 serves to guide out light more uniformly and softly. The embedded light shielding wall 112 of the light shielding member 111 surrounds the light transmitting body 133, i.e. the embedded light shielding wall 112 substantially surrounds the light transmitting body 133, so that the light of the light transmitting body 133 can be effectively prevented from being transmitted out through the wind turbine housing 200 along the radial direction by the shielding effect of the embedded light shielding wall 112.

Further, the light guide 130 is integrally injection molded with the light shielding member 111. Compared with the light guide member 130 and the light shielding member 111 which are respectively processed into two members, the light guide member 130 and the light shielding member 111 are integrally injection molded in a manner of fixing connection such as buckling, scarf joint and welding, so that on one hand, the installation cost can be reduced, the assembly efficiency can be improved, and on the other hand, the connection strength of the light guide member 130 and the light shielding member 111 can be ensured. The light guide 130 and the light shielding member 111 are integrally injection molded, and then the two may be specifically molded by two-shot molding or two-shot molding.

Further, the light guide 130 is two-shot molded with the light shielding member 111. Compared with the light guide member 130 and the light shielding member 111 which are formed by two-shot injection, the two-shot injection of the light guide member 130 and the light shielding member 111 can reduce one set of mold, and has low processing cost and low reject ratio.

In an embodiment, referring to fig. 5 and fig. 8 to fig. 11, the light guide 130 further includes a light-transmitting ring 140, and the light-transmitting ring 140 is connected to the rear outer periphery of the light-transmitting body 133; in the axial direction of the embedded light shielding surrounding wall 112, the light transmitting ring 140 is located outside the embedded light shielding surrounding wall 112, so that the light transmitting ring 140 is at least partially exposed out of the wind turbine housing 200.

In this embodiment, in order to improve structural strength, the light-transmitting ring 140 is optionally integrally formed with the light-transmitting body 133. By arranging the light-transmitting main body 133, light is guided to the light-transmitting ring 140 by the light source mounting cavity 113, compared with the light which is directly transmitted to the light-transmitting ring 140 by air, the light transmitted out can be more uniform and soft, and the overall light-emitting effect of the tail cover structure 100 can be improved. The light-transmitting ring 140 may be a circular ring, a rectangular ring, a petal ring, other special-shaped rings, etc., and the specific shape thereof may be selected and designed according to practical requirements. By disposing the light-transmitting ring 140 outside the embedded light-shielding surrounding wall 112, such that the light-transmitting ring 140 is at least partially exposed out of the air duct shell 200, the user can directly observe the light transmitted by the light-transmitting ring 140 from the rear end of the blower. The control panel can control the light source 150 to emit light rays with different colors and/or brightness according to different wind temperatures, so that a user can obtain different temperature information or visual effects through different light rays emitted by the light-transmitting ring 140, and the convenience of the user is improved.

In an embodiment, as shown in fig. 1 to 4 and fig. 7 to 11, the tail cover structure 100 of the blower further includes a light shielding end cover 160, the light shielding end cover 160 is fixedly covered on a side of the light-transmitting main body 133 facing away from the light shielding member 111, and the light-transmitting ring 140 surrounds the periphery of the light shielding end cover 160.

In this embodiment, the light shielding end cap 160 and the light transmitting body 133 may be fixedly connected by means of clamping, caulking, bonding, ultrasonic welding, etc. The light shielding end cover 160 is used for shielding the rear end of the light transmitting body 133, so as to prevent light from being transmitted out of the air duct shell 200 from the light transmitting body 133. Thus, the whole tail cover structure 100 can only transmit light through the light transmitting ring 140, and the overall visual effect can be improved. The light shielding end cap 160 may be made of a light shielding material, or may be coated with a light shielding layer only on the outer surface, so long as a light shielding effect can be achieved. In addition, the appearance color of the light shielding end cap 160 may be set to be the same as the appearance color of the blower case 200, so that the consistency of the appearance of the entire blower can be ensured.

Further, one of the wall surface of the light-transmitting body 133 facing the light-shielding end cap 160 and the wall surface of the light-shielding end cap 160 facing the light-transmitting body 133 is provided with a caulking groove 134, and the other is provided with a protrusion 161 adapted to the caulking groove 134.

In this embodiment, the light-transmitting body 133 and the light-shielding end cover 160 are matched through the protrusion 161 and the caulking groove 134, so that the alignment accuracy of the light-transmitting body 133 and the light-shielding end cover 160 can be ensured, and the assembly efficiency and accuracy of the light-transmitting body 133 and the light-shielding end cover 160 can be improved. The number of the caulking groove 134 and the projection 161 may be set to only one or a plurality, and is not particularly limited herein. Specifically, in order to improve the assembly accuracy of the light-transmitting body 133 and the light-shielding end cap 160, the assembly efficiency is improved, and the caulking groove 134 and the protrusion 161 may be both provided in a ring shape. Optionally, the light-transmitting main body 133 is provided with a caulking groove 134, and the light-shielding end cover 160 is provided with a protrusion 161 adapted to the caulking groove 134. It will be appreciated that since the light-shielding end cap 160 mainly plays a role of light shielding, the thickness of the light-shielding end cap 160 is generally set to be thin. By providing the protrusion 161 on the light shielding end cap 160, the structural strength of the light shielding end cap 160 can be ensured as compared with the case where the caulking groove is provided on the light shielding end cap 160. In other embodiments, the protrusion 161 may be disposed on the light-transmitting body 133, and the caulking groove 134 may be disposed on the light-shielding end cap 160.

Further, in the axial direction of the embedded light shielding surrounding wall 112, the width of the light transmitting ring 140 is smaller than the width of the embedded light shielding surrounding wall 112. The light-transmitting ring 140 mainly plays a role of molding and transmitting light, if the width of the light-transmitting ring 140 is too large, the light intensity can be affected, and the thickness of the whole tail cover structure 100 can be increased, which is not beneficial to the miniaturization of the whole machine. The embedded light shielding surrounding wall 112 mainly plays a role in installing the whole tail cover structure 100 in the air duct shell 200, and in order to ensure the connection strength, the width of the embedded light shielding surrounding wall 112 needs to be set larger. Therefore, the width of the light-transmitting ring 140 is smaller than the width of the embedded light-shielding surrounding wall 112, so that the widths of the light-transmitting ring 140 and the embedded light-shielding surrounding wall 112 are suitable, the thickness of the whole tail cover structure 100 is reduced as much as possible while the stable connection between the whole tail cover structure 100 and the wind cylinder shell 200 is ensured, and the miniaturization of the whole machine is facilitated.

In an embodiment, referring to fig. 8 to 11, the light-transmitting body 133 includes an end wall 135 and a light-guiding wall 137 connected between the end wall 135 and the light-transmitting ring 140, and the light-guiding wall 137 is disposed obliquely from front to back and outwards from the end wall 135; the embedded light shielding surrounding wall 112 surrounds the periphery of the light guiding wall 137, and the light transmitting ring 140 is abutted with the embedded light shielding surrounding wall 112 in the axial direction. The embedded light shielding surrounding wall 112 is adapted to surround the periphery of the light guiding wall 137, so as to effectively shield the light that is transmitted from the light guiding wall 137 along the radial direction of the wind turbine housing 200. The inclined light guide wall 137 can better guide the light in the light source 150 installation seat outwards to the position of the light-transmitting ring 140 to be transmitted.

Further, the embedded light shielding surrounding wall 112 has an inclined wall surface 114 adapted to fit with the inner wall surface of the light guiding wall 137, and the light transmitting ring 140 is overlapped with the outer end surface of the embedded light shielding surrounding wall 112.

In this embodiment, the embedded light shielding surrounding wall 112 is provided with an inclined wall surface 114 adapted to be attached to the inner wall surface of the light guiding wall 137, so that the embedded light shielding surrounding wall 112 is adapted to be attached to the light guiding wall 137, and the assembly of the light transmitting member on the light shielding member 111 can be limited in the axial direction and the radial direction at the same time; the matching light-transmitting ring 140 is lapped on the outer end surface of the embedded light-shielding surrounding wall 112, so that the forming assembly between the light-transmitting piece and the light-shielding piece 111 is more convenient. By overlapping the light-transmitting ring 140 with the outer end face of the embedded light-shielding surrounding wall 112, that is, by making the outer peripheral face of the embedded light-shielding surrounding wall 112 substantially flush with the outer peripheral face of the light-transmitting ring 140. Thus, the flatness and consistency of the outer peripheral surface of the whole light guide seat 110 can be ensured, and meanwhile, the light guide seat 110 can be embedded in the air duct shell 200 more smoothly.

In an embodiment, as shown in fig. 3 to 6 and fig. 9 to 11, the light guide seat 110 further includes a light shielding member 111 connected to the light guide member 130, the light shielding member 111 is made of a light shielding material, the light shielding member 111 further includes a mounting ring 116, the mounting ring 116 is connected to an inner wall surface of the embedded light shielding surrounding wall 112 and is located inside the inclined wall surface 114, the light-transmitting main body 133 further includes a connecting portion 138 connected to an inner wall surface of the end wall 135, and the connecting portion 138 is fixedly connected to the mounting ring 116.

In this embodiment, the mounting ring 116 is optionally integrally formed with the embedded light shielding enclosure wall 112 for structural strength.
