[0060] Example 1

[0061] refer to Figure 1-Figure 7 The present embodiment provides a panel structure 100, including a panel 1, a lamp body 2, a lifting assembly 3 and a driving assembly 4, wherein the lamp body 2 is connected to the lifting assembly 3. The driving assembly 4 drives the lifting assembly 3 to enable the lamp body 2 to perform telescopic or lifting motion relative to the panel 1, thereby adjusting the relative position of the lamp body 2 and the panel 1.

[0062] The panel 1 includes a base 11, a face 12, and a receiving cavity 13. The base 11 is used to install the lifting assembly 3 and the driving assembly 4, and the face 12 presents the appearance of the panel 1. During use, the face 12 faces the user below. The receiving cavity 13 is recessed downward from the face 12 toward the base 11, and is used to receive the lamp body 2. The base 11 is provided with a base surface 111 and a mounting groove 112, and the mounting groove 112 is formed by the base surface 111 extending away from the face 12. Figure 1 As shown, relative to the upper face portion 12, the mounting groove 112 is formed by the base surface 111 being recessed downward. The base surface 111 is a plane, and when the lamp body 2 is received in the accommodating cavity 13, the lamp body is closely connected to the base surface 111.

[0063] A first air inlet 121 is provided on the face portion 12. When air needs to enter through the first air inlet 121, the lamp body 2 will protrude from the accommodating cavity 13. The lamp body 2 is flexibly connected to the panel 1. By adjusting the relative position of the lamp body 2 relative to the panel 1, the first air inlet 121 can be partially or fully opened. A second air inlet 122 is provided on the base portion 11. The first air inlet 121, the accommodating cavity 13 and the second air inlet 122 are connected to each other.

[0064] The lifting assembly 3 is used to perform lifting (telescopic) adjustment on the lamp body 3, and the lifting assembly 3 includes a lifting bracket 31 and a rack 32. The lifting bracket 31 includes a first adjustment arm 311 and a second adjustment arm 312. In this embodiment, the first adjustment arm 311 and the second adjustment arm 312 are respectively provided in two, and the two first adjustment arms 311 are connected to the lamp body 2. Among the two second adjustment arms 312, one of the second adjustment arms 312 is transmission-connected with the rack 32, that is, the rack 32 drives one of the second adjustment arms 312 to move; the other second adjustment arm 312 is hinged on the base 11. In this embodiment, the rack 32 is a plate-like structure with a plurality of saw teeth.

[0065] The driving assembly 4 includes a motor 41 and a gear 42 . The motor 41 is a stepping motor. The motor 41 drives the gear 42 to rotate, and the rack 32 is meshedly connected with the gear 42 .

[0066] It should be noted that, in this embodiment, the lifting assembly 3 and the driving assembly 4 are jointly arranged in the mounting groove 112. The motor 41 drives the gear 42 to rotate, and drives the lamp body 2 to be stored or protruded from the accommodating cavity 13 through the lifting assembly 3, so that the lamp body 2 performs a lifting or telescopic up and down movement relative to the panel 1.

[0067] Specifically, when the blowing function is not needed, the lamp body 2 is stored in the accommodating cavity 13, and at this time, the light emitting plate of the lamp body 2 is flush with the face or recessed relative to the face.

[0068] When it is necessary to provide a blowing function, such as hot air flow or cold air flow, the motor 41 works and drives the gear 42 to rotate, driving the rack 32 to slide, and the rack 32 will push a second adjustment arm 312 of the lifting bracket 31 to move, so that the distance between the two second adjustment arms 312 is reduced, and the distance between the first adjustment arm 311 and the second adjustment arm 312 located on the same side is increased. In this way, the lamp body 2 connected to the first adjustment arm 311 will protrude from the accommodating cavity 13, and it can be considered that the lamp body 2 is separated from the panel 1, and the first air inlet 121 is partially or completely opened, and the airflow enters the accommodating cavity 13 through the first air inlet 121, and then enters the wind cavity connected to the panel 1 through the second air inlet 122 for heating or cooling, and finally provides hot air flow or cold air flow.

[0069] Furthermore, the panel 1 includes a frame 14, and the frame 14 includes a first frame 141 and a second frame 142, wherein the first frame 141 extends along a first direction L1, and the second frame 142 extends along a second direction L2. The first direction L1 is perpendicular to the second direction L2.

[0070] The frame 14 of this embodiment is a rectangular structure. In other embodiments, the frame 14 may also be a regular pentagon, a regular hexagon or other frame structures. Preferably, two first frames 141 and two second frames 142 form a rectangular frame 14, and the first frame 141 is longer than the second frame 142; at the same time, the first frame 141 and the second frame 142 together surround the accommodating cavity 13 inside. In some embodiments, the length of the first frame 141 is the same as the length of the second frame 142, and the frame 14 is a square structure.

[0071] Furthermore, one of the two first frames 141 is wider and the other is narrower. The wider first frame is the first wide frame 141A, which can be used to install a digital display screen 1411 that displays control values ​​such as temperature and wind speed.

[0072] The mounting groove 112 includes a first groove body 1121 and a second groove body 1122 . The first groove body 1121 is opened parallel to the first direction L1 , the second groove body 1122 is opened parallel to the second direction L2 , and the second groove body 1122 is connected to the first groove body 1121 .

[0073] like Figure 3 As shown, the base 11 is provided with two substantially L-shaped mounting grooves 112, and the two mounting grooves 112 are arranged in alignment. The motor 41 is installed in the first groove 1121, and the lifting assembly 3 is installed in the second groove 1121. Driven by the motor 41, the rack 32 drives one of the second adjustment arms 312 of the lifting bracket 31 to slide in the second groove 1122 along the second direction L2. The lifting assembly 3 is installed in the second groove 1121 that is symmetrically (aligned), which can improve the stability of the lifting adjustment.

[0074] Combined with reference Figure 1 and Figure 3 The base surface 111 has a normal line Z, and the direction parallel to the normal line Z of the base surface 111 is the third direction L3. Driven by the lifting bracket 31, the lamp body 2 moves up and down relative to the panel 1 along the third direction L3.

[0075] like Figure 4 As shown, the lamp body 2 includes a lamp frame 21, a light emitting plate 22 and a light source module 23, and the lamp frame 21 and the light emitting plate 22 surround and form a light emitting cavity 20. The light source module 23 is a long strip of light, and the light source module 23 is fixedly mounted on the lamp frame 21 and is located in the light emitting cavity 20. An air inlet gap 24 is formed between the lamp frame 21 of the lamp body 2 and the frame 14 of the panel 1. The first air inlet 121, the air inlet gap 24, (part of) the accommodating cavity 13 and the second air inlet 122 constitute an air inlet duct.

[0076] In the panel structure of the present embodiment, the lamp body is made to protrude from the accommodating cavity of the panel by means of the lifting assembly, so as to adjust the opening size of the first air inlet 131 and the air flow direction of the air inlet gap 24 .

[0077] Combined with reference Figure 4 and Figure 5 , Figure 5 for Figure 4 The cross-sectional view along the BB line in FIG. 2 is parallel to the second direction L2. The lamp frame 21 includes a bottom plate 211, a side plate 212 and a top plate 213. The bottom plate 211 is parallel to the base surface 111. Figure 5 As shown, along the second direction L2, in the cross section of the lamp body 2, the bottom plate 211 and the side plate 212 form an inverted trapezoidal structure, and the top plate 213 and the light emitting plate 22 form a rectangular structure. That is, the cross section of the lamp body 2 is a combination of an inverted trapezoid and a rectangle. To match the lamp body 2, the cross section of the accommodating cavity 13 is also a combination of an inverted trapezoid and a rectangle; in addition, the opening size of the accommodating cavity 13 is equal to or slightly larger than the overall size of the lamp body 2, so as to accommodate and place the lamp body 2.

[0078] The bottom plate 211 is provided with a first mounting seat 251 and a second mounting seat 252, which are used to cooperate with the first adjustment arm 311. The first mounting seat 251 and the second mounting seat 252 are formed by extending from the bottom plate 211 toward the direction close to the light output plate 22. A first mounting position 253 is provided on the first mounting seat 251, and the first mounting position 253 is a runway-shaped groove structure; a second mounting position 254 is provided on the second mounting seat 252, and the second mounting position 254 is a circular through-hole structure.

[0079] like Figure 5 and Figure 6 As shown, one of the first adjustment arms 311 is slidably connected to the first mounting seat 251; that is, the first adjustment arm 311 on the left side can slide along the first mounting position 253. The other first adjustment arm 311 is hinged on the second mounting seat 252; that is, the first adjustment arm 311 on the right side is hingedly installed in the second mounting position 244. The second adjustment arm 312 on the right side is hingedly installed on the base 11.

[0080] The motor 41 drives the gear 42 to rotate, and further pushes the second adjustment arm 312 on the left side of the lifting bracket 31 to move through the rack 32. At this time, the first adjustment arm 311 on the left side slides from left to right along the first installation position 253, so that the distance between the two first adjustment arms 311 is reduced, and the distance between the two second adjustment arms 312 is also reduced. At this time, the distance between the first adjustment arm 311 and the second adjustment arm 312 on the same side is increased, so that the lamp body 2 can protrude from the accommodating cavity 13.

[0081] Figure 7 for Figure 6The enlarged schematic diagram of part C in the middle, combined with reference Figure 6 and Figure 7 The lifting assembly 3 of this embodiment also includes a transmission member 33, which is used to connect the rack 32 and the lifting bracket 31. The transmission member 33 includes a first transmission part 331 and a second transmission part 332, and the second transmission part 332 and the first transmission part 331 are stamped as a whole. Among them, the first transmission part 331 is fixedly connected to the rack 32. Specifically, the rack 32 is provided with a connecting groove 321 at the end, and the fastener 322 fits the first transmission part 331 on the connecting groove 321. In some embodiments, the transmission member 33 can be an integrally formed structure with the rack 32; in other embodiments, the transmission member 33 can also be fixed to the first transmission part 331 on the connecting groove 321 by bonding, riveting or welding.

[0082] The second transmission part 332 is formed by the first transmission part 331 being bent in an arc shape toward the bottom surface 1120 of the installation groove, and then extending obliquely toward the direction away from the bottom surface 1120 of the installation groove. The second transmission part 332 is provided with a transmission surface 333, and the transmission surface 333 is an inclined surface, that is, there is an angle θ between the transmission surface 333 and the bottom surface 1120 of the installation groove, and the value range of the angle θ is 0°<θ≤10°. One of the second adjustment arms 312 abuts against the transmission surface 333.

[0083] Furthermore, the transmission member 33 is provided with a limit block 334 and a connection block 335 on the second transmission part 332. The limit block 334 and the connection block 335 are formed to extend from the second transmission part 332 in a direction away from the transmission surface 333, and are used to limit the second adjustment arm 312 in the first direction (front-rear direction). In some embodiments, the connection block 334 is connected to the second adjustment arm 312 in a movable latch connection.

[0084] The limiting block 334 of the present embodiment is a columnar structure; in other embodiments, the limiting block 334 may directly extend upward from the bottom surface 1120 of the installation groove to form a plate-like structure.

[0085] Further references Figure 7 The lifting assembly 3 further includes a ball 34, which is disposed between the rack 32 and the mounting groove 112. The ball 34 is used to make the rack 32 slide smoothly in the second groove body 1122 of the mounting groove 112 to reduce friction. Specifically, the rack 32 includes a sliding plate 323 and a latch 324, and a plurality of latches are disposed on the sliding plate 323. The rack 32 is provided with a connecting groove 321 at the latch 342 near the transmission member 33, which is used to be fixedly connected with the first transmission part 331.

[0086] The mounting groove 112 is recessed in the direction away from the mounting groove bottom surface 1120 at the second groove body 1122 to form a ball sliding groove 1123. The ball 34 is arranged in the ball sliding groove 1123 and contacts the sliding plate 323 of the rack 32, so that the rack 32 moves smoothly in the second groove body 1122.

[0087] In the panel structure provided in this embodiment, the motor drives the gear to rotate, and then drives the rack to slide smoothly in the second groove body. The rack pulls the lifting bracket through the transmission member, and finally the lifting bracket drives the lamp body to protrude or be stored in the accommodating cavity through the first adjusting arm, thereby adjusting the position of the lamp body relative to the panel, which is convenient for adjusting the air intake rate and air intake volume; in addition, the driving assembly and the lifting assembly are jointly arranged in the recessed installation groove, which saves space without affecting the flow direction of the airflow.

[0088] Example 2

[0089] exist Figure 1-Figure 7 Based on reference Figure 8 In the panel structure 100 of this embodiment, the lifting assembly 3 includes a lifting bracket 31 and a rack 32. The lifting bracket 31 includes two bracket monomers 310 movably connected together, and each bracket monomer 310 has a first adjustment arm 311 and a second adjustment arm 312.

[0090] A through hole is provided at the center of the bracket monomer 310, and the central screw 3101 passes through the through holes of the two bracket monomers 310 in sequence and connects the two to form an X-shaped lifting bracket structure. It should be noted that the central screw 3101 does not completely lock the two bracket monomers 310, but allows the two to move relative to each other while maintaining the locking force.

[0091] In some embodiments, multiple lifting brackets can be added on the basis of one lifting bracket 31. For example, the first adjustment arm 311 of one lifting bracket is connected to the second adjustment arm 312 of another lifting bracket located above it; for another example, the second adjustment arm 312 of one lifting bracket is connected to the first adjustment arm 311 of another lifting bracket located below it. In a lifting assembly with multiple lifting brackets, the first adjustment arm 311 of the lifting bracket located at the top is connected to the lamp body 2; the second adjustment arm 312 of the lifting bracket located at the bottom is connected to the panel and driven by the driving assembly 4. By increasing the number of lifting brackets, the lifting height of the lamp body is increased.

[0092] The driving assembly 4 includes a stepping motor 41 and a gear 42 drivingly connected to the motor 41. The driving assembly 4 is installed in the first slot 1121. The rack 32 and the lowermost lifting assembly are installed in the second slot 1122. In addition, the rack 32 is connected to the second slot 1122 through a ball 34 to reduce friction during sliding.

[0093] The panel structure provided in this embodiment uses a single or multiple lifting brackets of a rack transmission type to adjust the protruding height of the lamp body and the air duct, thereby adjusting the blowing speed and blowing range.

This embodiment is described by taking the fan as a bathroom heater, but it is not limited to this.

[0096] The air outlet device includes a box body 200 and a panel structure 100 of embodiment 1 or embodiment 2. The box body 200 is provided with a fan 201 and a receiving groove 202, and the panel structure 100 is installed in the receiving groove 202. The panel 1 is fixedly connected to the box body 200, and the base 11 of the panel 1 is provided with a second air inlet 122, and the fan 201 is arranged below the second air inlet 122.

[0097] In some embodiments, the fan 201 is adjacent to the PTC thermistor, and the fan 201 blows the heat generated by the PTC thermistor to the outside in the form of hot air flow.

[0098] like Fig.11 As shown, when the air outlet device does not need to provide hot air flow to the outside, the fan does not work, and the air outlet device can selectively provide lighting function. At this time, the lamp body 2 does not protrude from the panel 1. That is, the lamp body 2 covers the entire accommodating cavity 13, which can reduce foreign matter from entering the box body 200 and keep it clean.

[0099] like Fig.12 As shown, when the air outlet device needs to provide hot air flow to the outside, the fan works. At this time, the lamp body 2 protrudes from the panel 1. Specifically, the motor drives the gear to rotate, and further pushes a second adjustment arm on the left side of the lifting bracket to move through the rack. At this time, the first adjustment arm on the left side slides from left to right, so that the distance between the two first adjustment arms is reduced, and the distance between the two second adjustment arms is also reduced. The distance between the first adjustment arm and the second adjustment arm on the same side increases, so that the lamp body 2 can protrude from the accommodating cavity 13.

[0100] The airflow passes through the first air inlet and the air inlet gap, enters the containing cavity, and then passes through the second air inlet into the air cavity connected to the panel. After being heated by the PTC thermistor, the fan provides hot air flow to the outside.

[0101] The air outlet device provided in this embodiment can control the telescopic distance of the lamp body to be within 0-25 mm. According to the power of the PTC thermistor, the lifting (telescopic) distance and the air inlet gap are adjusted as required to adjust the air intake volume.

[0102] The above contents are merely examples and illustrations of the structure of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, and these obvious replacement forms all belong to the protection scope of the present invention.
