[0002] Air-heated bathroom heaters are commonly used for heating bathrooms. Air-heated bathroom heaters have fans, and fans need to be equipped with air inlets and outlets.

[0042] like Figure 1-4 As shown, a wind-heated bathroom heater includes a shell 4, on which an air inlet 5 and an air outlet 6 are provided, and is characterized in that it also includes an air inlet baffle 1 and an air outlet baffle 2 for respectively shielding the air inlet 5 and the air outlet 6, and the air inlet baffle 1 and the air outlet baffle 2 are respectively matched with a driving mechanism 400, and the driving mechanism 400 can drive the air inlet baffle 1 to leave the air inlet 5, and drive the air outlet baffle 2 to leave the air outlet 6.

[0043] The air-heated bathroom heater created by the present invention only needs one driving mechanism 400 to drive the air inlet baffle 1 and the air outlet baffle 2 to move respectively. When working, the air inlet baffle 1 and the air outlet baffle 2 leave the air inlet 5 and the air outlet 6 respectively to allow air to pass through. When not working, the air inlet baffle 1 and the air outlet baffle 2 respectively block the air inlet 5 and the air outlet 6 to prevent water vapor and dust from entering. It has the characteristics of compact structure and small size.

[0044] The following is combined with Figures 1 to 21 The given examples further illustrate the specific implementation of the air-heated bathroom heater created by the present invention. The air-heated bathroom heater created by the present invention is not limited to the description of the following examples.

[0045] like Figure 1-4 As shown, the air-heated bathroom heater created by the present invention includes a shell 4, on which an air inlet 5 and an air outlet 6 are provided, and also includes an air inlet baffle 1 and an air outlet baffle 2 for respectively shielding the air inlet 5 and the air outlet 6. The air inlet 5 is connected to one side of the air outlet 6, and the air inlet baffle 1 and the air outlet baffle 2 are respectively coordinated with a driving mechanism 400. The driving mechanism 400 can first drive the air inlet baffle 1 to leave the air inlet 5 and be spaced from the air inlet 5, and then drive the air outlet baffle 2 to leave the air outlet 6 and move to between the air inlet baffle 1 and the air inlet 5.

[0046] like Figure 3-4As shown, the air-heated bathroom heater of this embodiment is provided with two fans, which respectively constitute a warm air module 500 and a ventilation module 600. A heating element (not shown in the figure) is also provided in the warm air module 500, and the heating module is usually a PTC ceramic heating element.

[0047] The warm air module 500 is provided with a heating inlet 510 and a heating outlet 520. The air passes through the heating inlet 510, the heating element and the heating outlet 520 in sequence. The air is heated when passing through the heating element and can play a role of heating after returning to the bathroom.

[0048] The ventilation module 600 is provided with a ventilation inlet 610 and a ventilation outlet 620. The ventilation outlet 620 is connected to the outside through an exhaust duct (not shown in the figure). The air in the bathroom is discharged to the outside through the ventilation inlet 610, the ventilation outlet 620 and the exhaust duct in sequence.

[0049] The air inlet baffle 1 of this embodiment is used to shield the heating inlet 510 of the warm air module 500 and the ventilation inlet 610 of the ventilation module 600 , and the air outlet baffle 2 is used to shield the heating outlet 520 of the warm air module 500 .

[0050] Specifically, the shell 4 includes a semi-box-shaped box body, and the air inlet 5 and the air outlet 6 are formed by the opening on the top of the box body. The air inlet baffle 1 and the air outlet baffle 2 are respectively used to block the air inlet 5 and the air outlet 6 formed by the opening on the top of the box body. A middle plate 7 is provided inside the box body, which is spaced apart from the air inlet baffle 1 and the air outlet baffle 2. The protective mesh cover 3 and a plurality of connecting rod mechanisms are provided on one side of the middle plate 7 close to the air inlet baffle 1 and the air outlet baffle 2. The warm air module 500 and the ventilation module 600 are provided on the other side of the middle plate 7 and fixed to the box body.

[0051] The heating inlet 510 and the heating outlet 520 of the heating module 500 are arranged adjacent to each other and are respectively arranged on the bottom surface of the shell 4. The ventilation inlet 610 and the ventilation outlet 620 of the ventilation module 600 are respectively arranged on different sides, and the ventilation outlet 620 is arranged on the side surface of the shell 4. The ventilation inlet 610 is arranged on the bottom surface of the shell 4 and is adjacent to the heating inlet 510. The ventilation inlet 610 and the heating inlet 510 are respectively arranged corresponding to the air inlet 5. Figure 4 It is located below the air inlet 5, but is usually located above the air inlet 5 during actual operation. The heating outlet 520 is arranged corresponding to the air outlet 6. Figure 4 It appears to be located below the air outlet 6, but is usually located above the air outlet 6 during actual operation.

[0052] Of course, only one of the heating module 500 and the ventilation module 600 may be provided. When the ventilation module 600 is not provided, the heating inlet 510 and the heating outlet 520 of the heating module 500 automatically constitute the air inlet 5 and the air outlet 6. In addition, the air inlet baffle 1 may also be used only to block the heating inlet 510, without blocking the entire air inlet 5. Then the air inlet 5 and the air outlet 6 are the heating inlet 510 and the heating outlet 520 of the heating module 500. The air inlet baffle 1 and the air outlet baffle 2 may also be combined into one baffle, which is driven by the first link mechanism 100 and the second link mechanism 200. After the first link mechanism 100 drives the baffle to block the air inlet 5, the second link mechanism 200 continues to drive the baffle to block the air outlet 6.

[0053] like Figure 2 , 4 As shown, the air-heated bathroom heater of this embodiment also includes a protective mesh cover 3 cooperating with a driving mechanism 400. The driving mechanism 400 can drive the protective mesh cover 3 to move to the air outlet 6 after the air outlet baffle 2 leaves the air outlet 6. The protective mesh cover 3 is used to protect the interior of the bathroom heater. At the same time, the protective mesh cover 3 is a hollow structure to allow air to pass through.

[0054] Furthermore, the driving mechanism 400 is arranged between the ventilation inlet 610 of the ventilation module 600 and the heating inlet 510 of the warm air module 500, and is located in the interlayer between the warm air module 500 and the ventilation module 600, and between the air inlet baffle 1 and the air outlet baffle 2. The air inlet baffle 1, the air outlet baffle 2 and the protective mesh cover 3 are respectively coordinated with the driving mechanism 400 through a connecting rod mechanism, and the driving mechanism 400 can push the connecting rod mechanisms corresponding to the air inlet baffle 1, the air outlet baffle 2 and the protective mesh cover 3 in turn.

[0055] Specifically, the connecting rod mechanism connected to the air inlet baffle 1 is a first connecting rod mechanism 100 ( Figure 11-13 ), a second link mechanism 200 (connected to the air outlet baffle 2) Figure 16-17 ), the link mechanism connected to the protective mesh cover 3 is the third link mechanism 300 ( Figure 20-21 ), the driving mechanism 400 can push the first link mechanism 100, the second link mechanism 200 and the third link mechanism 300 in sequence, so that the protective mesh cover 3 moves to the air outlet 6 driven by the first link mechanism 100 after the air outlet baffle 2 leaves the air outlet 6, to prevent the outside from contacting the inside of the bathroom heater, and to prevent the air outlet 6 from lacking protective measures after the air outlet baffle 2 leaves. Of course, the protective mesh cover 3 may not be provided, or the protective mesh cover 3 may be fixed to one side of the air outlet 6 and not move, which all fall within the protection scope of the invention.

[0056] When the bathroom heater needs to be turned on, the driving mechanism 400 can sequentially push the first link mechanism 100, the second link mechanism 200 and the third link mechanism 300:

[0057] First, the first link mechanism 100 drives the air inlet baffle 1 to leave the air inlet 5, exposing the air inlet 5 while avoiding the air outlet baffle 2, so that the air inlet 5 can allow air to enter the bathroom heater;

[0058] Then, the second connecting rod mechanism 200 drives the air outlet baffle 2 to move between the air inlet 5 and the air inlet baffle 1, so that the air outlet baffle 2 leaves the air outlet 6. When the air outlet 6 is exposed, the air outlet 6 allows the heated air in the bathroom heater to leave.

[0059] Finally, the third connecting rod mechanism 300 drives the protective mesh cover 3 to move to the air outlet 6. The protective mesh cover 3 can prevent the outside from contacting the internal parts of the bathroom heater.

[0060] When the bathroom heater needs to be turned off, the driving mechanism 400 moves in the opposite direction, pushing the third link mechanism 300, the second link mechanism 200 and the first link mechanism 100 in sequence:

[0061] First, the third link mechanism 300 drives the protective net cover 3 to move to the inside of the bathroom heater, away from the air outlet 6 to avoid the air outlet baffle 2;

[0062] Then the second link mechanism 200 drives the air outlet baffle 2 to move to the air outlet 6, and the air outlet baffle 2 blocks the air outlet 6, while avoiding the air inlet baffle 1;

[0063] Finally, the first connecting rod mechanism 100 drives the air inlet baffle 1 to move to the air inlet 5 , and the air inlet 5 is blocked by the air inlet baffle 1 .

[0064] like Figure 4 As shown, the driving mechanism 400 of this embodiment is correspondingly arranged between the ventilation module 600 and the heating module 500. Figure 8 As shown, the driving mechanism 400 includes a turntable 410 and a driving shaft 411 connected to the turntable 410 . The turntable 410 is connected to a motor 430 . When the motor 430 drives the turntable 410 to rotate, the driving shaft 411 rotates around the center of the turntable 410 .

[0065] The first link mechanism 100, the second link mechanism 200 and the third link mechanism 300 are arranged in sequence on one side of the rotation path of the driving shaft 411. When the driving shaft 411 rotates to one side, it can push the first link mechanism 100, the second link mechanism 200 and the third link mechanism 300 to rotate in sequence. When the driving shaft 411 rotates to the other side, it can also push the third link mechanism 300, the second link mechanism 200 and the first link mechanism 100 in sequence in reverse.

[0066] It is understandable that the drive shaft 411 can also move linearly, especially when the third link mechanism 300 is not provided, the first link mechanism 100 and the second link mechanism 200 only need to be provided on one side of the moving path of the drive shaft 411. When the drive shaft 411 moves linearly to one side, it can push the first link mechanism 100 and the second link mechanism 200 in sequence, and when it moves to the other side, it can push the second link mechanism 200 and the first link mechanism 100 in sequence. However, by rotating the drive shaft 411, not only can the three link mechanisms be driven in sequence, but also it has the characteristic of occupying a small space.

[0067] like Figure 4-8 As shown, the principles of the first connecting rod mechanism 100, the second connecting rod mechanism 200 and the third connecting rod mechanism 300 are basically the same, and they respectively include a driving member 10, a crank member 20, a connecting rod member 30 and a sliding mechanism 40, one end of the three crank members 20 is fixedly connected to the corresponding driving member 10, the other end of the three crank members 20 is hinged to the sliding mechanism 40 through the connecting rod member 30, the three sliding mechanisms 40 are respectively connected to the corresponding air inlet baffle 1, the air outlet baffle 2 and the protective mesh cover 3, the three driving members 10 are sequentially arranged on one side of the rotation path of the driving shaft 411 to cooperate, the crank member 20 includes a vertically connected rotating shaft and a rotating arm, the other end of the rotating shaft connected to the rotating arm is fixedly connected to the corresponding driving member 10, the other end of the rotating arm connected to the rotating shaft is hinged to the corresponding connecting rod member 30, when the driving shaft 411 pushes the driving member 10 to rotate, the driving member 10 drives the rotating shaft to rotate, the rotating shaft drives the rotating arm to swing, and the rotating arm drives the sliding mechanism 40 to move through the connecting rod member 30.

[0068] Furthermore, the driving parts 10 of the first connecting rod mechanism 100, the second connecting rod mechanism 200 and the third connecting rod mechanism 300 are the same and are all gap cams, but the order in which the three gap cams contact the driving shaft 411 is different. The center of the gap cam is fixedly connected to the corresponding crank member 20, and a protrusion 11 is provided on one side of the center of the gap cam. A slide groove 12 extending toward the center of the gap cam is provided on the protrusion 11, and the driving shaft 411 can be inserted into the slide groove 12 and push the side wall of the slide groove 12 to drive the gap cam to rotate.

[0069] Furthermore, the driving mechanism 400 also includes a base 420 arranged opposite to the turntable 410, the gap cam is arranged between the base 420 and the turntable 410, the crank member 20 passes through the base 420 and is connected to the corresponding gap cam, and the gap cam is rotatably mounted on the base 420 through the corresponding crank member 20.

[0070] Specifically, the base 420 is fixedly connected to the middle plate 7, the turntable 410 is rotatably arranged between the base 420 and the middle plate 7, the motor 430 passes through the middle plate 7 and is connected to the center of the turntable 410, and a driving shaft 411 connected to the eccentric position of the turntable 410 is provided between the turntable 410 and the base 420. When the motor 430 drives the turntable 410 to rotate, the driving shaft 411 surrounds the center of the turntable 410 and pushes the three gap cams in sequence.

[0071] Further, the base 420 includes a fixed plate 421 and three fixed side plates 422 respectively connected to the fixed plate 421 on all sides, the fixed plate 421 is fixedly connected to the middle plate 7 through the fixed side plates 422, the three fixed side plates 422 are arranged at intervals along the circumference of the turntable 410, and three avoidance grooves 423 corresponding to the three gap cams are formed between adjacent fixed side plates 422, and the rotation center of the gap cam is located on the line connecting the center of the avoidance groove 423 to the center of the fixed plate 421;

[0072] The rotating disk 410 includes a rotating plate 412 arranged opposite to the fixed plate 421, and a rotating side plate 413 connected to the rotating plate 412. A clearance opening 414 for avoiding the gap cam is provided on one side of the rotating side plate 413. The driving shaft 411 is arranged on a line connecting the center of the clearance opening 414 to the center of the rotating plate 412. When the driving shaft 411 pushes the gap cam to rotate, the rotating side plate 413 and the fixed side plate 422 avoid the protrusion 11 on one side of the gap cam through the clearance opening 414 and the clearance groove 423 respectively, so as to prevent the protrusion 11 from being blocked by the rotating side plate 413 and the fixed side plate 422.

[0073] When the gap cam rotates into position, the protrusion 11 rotates back to the inner side of the rotating side plate 413 and the fixed side plate 422 and is limited. By limiting the protrusion 11 by the rotating side plate 413, not only can the gap cam be prevented from rotating freely after being in position, or continuing to rotate with the turntable 410, but the difficulty of assembly can also be reduced, so that the driving mechanism 400 and the gap cam can be assembled as one, and then installed on the middle plate 7 together.

[0074] like Figure 4-8 As shown, the difference between the first link mechanism 100, the second link mechanism 200 and the third link mechanism 300 of this embodiment is that the structure of the sliding mechanism 40 is different, and the lengths of the crank member 20 and the connecting rod member 30 are also different. The sliding mechanism 40 of the first link mechanism 100, the second link mechanism 200 and the third link mechanism 300 respectively includes a guide frame and a sliding frame slidably mounted on the guide frame, and the sliding frame is connected to the corresponding crank member 20 through the corresponding connecting rod member 30. When the crank member 20 rotates, the sliding frame is driven to slide on the guide frame through the connecting rod member 30.

[0075] Furthermore, the second link mechanism 200 and the third link mechanism 300 also include a retractable limiting mechanism 50 and a top rod 60 that is inclined with respect to the limiting mechanism 50. One end of the top rod 60 cooperates with the sliding mechanism 40, and the other end of the top rod 60 is connected to the retractable end of the limiting mechanism 50 through the air inlet baffle 1 or the protective mesh cover 3. The sliding mechanism 40 can push the top rod 60 to drive the connected air inlet baffle 1 or the protective mesh cover 3 to move along the telescopic direction of the limiting mechanism 50.

[0076] like Figure 14-17 2 shows the structure of the second connecting rod mechanism 200 of the present embodiment, wherein the driving member 10, the crank member 20 and the connecting rod member 30 of the second connecting rod mechanism 200 are respectively the second driving member 10, the second crank member 220 and the second connecting rod member 230;

[0077] The sliding mechanism 40 of the second connecting rod mechanism 200 includes a second guide frame 241 and a second sliding frame slidably mounted on the second guide frame 241. The second sliding frame is fixedly connected to the air outlet baffle 2, and the second sliding frame is hinged to the second crank member 220 through the second connecting rod member 230. When the second crank member 220 rotates, the second sliding frame is driven to slide on the second guide frame 241 through the second connecting rod member 230, and the second sliding frame drives the air outlet baffle 2 to approach and move away from the air outlet 6 from one side.

[0078] Specifically, the second sliding frame is a U-shaped structure, and the second sliding frame includes two second sliding rods 242 arranged in parallel, and two second connecting rods 243 respectively connected between the two second sliding rods 242, wherein the middle part of one of the second connecting rods 243 is hinged to one end of the second connecting rod member 230, and the other end of the second connecting rod member 230 is hinged to the second crank member 220;

[0079] It includes two second guide frames 241 connected to the middle plate 7 through the legs 244, the two second guide frames 241 correspond to the two second sliding rods 242, one side of the two second sliding rods 242 is connected to the two ends of the air outlet baffle 2, and the other side of the two second sliding rods 242 is slidably matched with the second guide frames 241. The second guide frame 241 is connected to the middle plate 7 through the legs 244, so that the second sliding frame can be set higher than the protective net cover 3 to avoid interference with the protective net cover 3.

[0080] like Figure 9-13 The structure of the first connecting rod mechanism 100 of this embodiment is shown, and the driving member 10, the crank member 20 and the connecting rod member 30 of the first connecting rod mechanism 100 are respectively the first driving member 110, the first crank member 120 and the first connecting rod member 130;

[0081] The first link mechanism 100 has the same working principle as the above-mentioned second link mechanism 200. The sliding mechanism 40 of the first link mechanism 100 also includes a first guide frame 141 and a first sliding frame 142 slidably mounted on the first guide frame 141. However, the difference is that the first link mechanism 100 adds a retractable first limiting mechanism 150 and a first top rod 160 inclined to the first limiting mechanism 150. The first limiting mechanism 150 is connected to the air inlet baffle 1. When the first top rod 160 pushes the air inlet baffle 1, the air inlet baffle 1 is limited to move in the telescopic direction of the first limiting mechanism 150, thereby driving the air inlet baffle 1 to move in a parallel direction to the air inlet 5. The horizontal movement of the first sliding frame 142 is converted into vertical movement through the first limiting mechanism 150 and the first top rod 160.

[0082] Specifically, the first limiting mechanism 150 includes a first pillar 151 and a first telescopic rod 152 coaxially arranged, and a first top rod 160 obliquely arranged on one side of the first pillar 151 and the first telescopic rod 152, the first pillar 151 is fixed on the middle plate 7, one end of the first telescopic rod 152 is inserted into the first pillar 151, the other end of the first telescopic rod 152 is respectively hinged to the air inlet baffle 1 and one end of the first top rod 160 through a first upper rotating shaft 161, and the other end of the first top rod 160 is hinged to the first sliding frame 142 through a first lower rotating shaft 162;

[0083] When the air inlet 5 is opened, the first sliding frame 142 drives the first push rod 160 to approach the first support 151. Since the first support 151 is fixed on the middle plate 7, the first support 151 limits the first push rod 160 through the first telescopic rod 152. The component force of the first push rod 160 acting on the first telescopic rod 152 can only drive the first telescopic rod 152 to extend out of the first support 151, thereby driving the air inlet baffle 1 away from the air inlet 5.

[0084] When the air inlet 5 is closed, the first sliding frame 142 drives the first push rod 160 away from the first support 151 , and the first push rod 160 pulls the first telescopic rod 152 to retract into the first support 151 , thereby driving the air inlet baffle 1 to return to the air inlet 5 .

[0085] Further, the first sliding frame 142 includes two first sliding frames 142 arranged in parallel, and a first connecting rod 143 connected between the first sliding frames 142, the middle portion of the first connecting rod 143 is hinged to one end of the first connecting rod member 130, and the other end of the first connecting rod member 130 is hinged to the first crank member 120;

[0086] The first sliding frame 142 is a frame-shaped structure, and the first sliding frame 142 is sleeved around the first top rod 160. The first lower rotating shaft 162 passes through the first top rod 160 and two opposite side walls of the first sliding frame 142, so that the first top rod 160 is rotatably connected to the first sliding frame 142. The first guide frame 141 is a frame-shaped structure and sleeved on the outside of the first sliding frame 142, and slidably cooperates with the first sliding frame 142. On the two opposite side walls of the first guide frame 141, there are respectively provided with a clearance groove 144 for avoiding the first lower rotating shaft 162.

[0087] The first guide frame 141 of this embodiment is integrally formed with the middle plate 7, which is convenient for processing and assembly. The first guide frame 141 can also be processed separately and then installed on the middle plate 7, which belongs to the protection scope of the invention. In addition, the first sliding frame 142 of this embodiment is a frame-shaped structure with higher strength. The first sliding frame 142 is sleeved around the bottom end of the first top rod 160, and the connection is more reliable.

[0088] like Figure 18-21 The structure of the third connecting rod mechanism 300 of this embodiment is shown, and the driving member 10, the crank member 20 and the connecting rod member 30 of the third connecting rod mechanism 300 are respectively a third driving member 310, a third crank member 320 and a third connecting rod member 330;

[0089] The third link mechanism 300 has the same working principle as the above-mentioned first link mechanism 100. The third link mechanism 300 includes a third guide frame 341, a third sliding frame slidably mounted on the third guide frame 341, and a retractable third limiting mechanism 350. The third guide frame 341, the third sliding frame and the third limiting mechanism 350 respectively correspond to the first guide frame 141, the first sliding frame 142 and the first limiting mechanism 150 of the first link mechanism 100.

[0090] The third limiting mechanism 350 includes a coaxially arranged third pillar 351 and a third telescopic rod 352, and an inclined third top rod 360, but the third telescopic rod 352 is not connected to the third top rod 360 (the first top rod 160 is connected to the first telescopic rod 152), and the third telescopic rod 352 and the third top rod 360 are located on both sides of the protective mesh cover 3 and are respectively connected to the protective mesh cover 3.

[0091] The third pillar 351 is fixed on the middle plate 7, one end of the third telescopic rod 352 is inserted into the third pillar 351 for sliding cooperation, the other end of the third telescopic rod 352 is fixedly connected to one side of the protective net cover 3, one end of the third top rod 360 is hinged to the third sliding frame, and the other end of the third top rod 360 is hinged to the other side of the protective net cover 3.

[0092] The third support column 351 is fixed on the middle plate 7. The third telescopic rod 352 cannot directly limit the first top rod 160 like the first telescopic rod 152. Instead, the third telescopic rod 352 limits the third top rod 360 through the protective mesh cover 3, so that the component force of the third top rod 360 acting on the protective mesh cover 3 can only drive the third telescopic rod 352 to extend and retract the third support column 351, and then drive the protective mesh cover 3 to move in a direction parallel to the air outlet 6, thereby realizing a movement similar to that of the air inlet baffle 1.

[0093] Furthermore, the third sliding frame includes two third sliding rods 342 arranged in parallel, and a third connecting rod 343 connected between the two third sliding rods 342, the middle part of the third connecting rod 343 is hinged to one end of the third connecting rod member 330, and the other end of the third connecting rod member 330 is hinged to the corresponding crank member 20, each third sliding rod 342 is respectively hinged to one end of two third push rods 360, and the other end of the third push rod 360 is respectively hinged to the protective net cover 3, and the third guide frame 341 is provided with a guide groove, and the third sliding rod 342 is inserted into the guide groove of the third guide frame 341 in an L-shaped structure for sliding cooperation.

[0094] The third guide frame 341 of this embodiment is also integrally formed with the middle plate 7, and the guide groove on the third guide frame 341 can be directly processed on the middle plate 7, which is convenient for processing and assembly. Of course, the third guide frame 341 can also be processed separately and then installed on the middle plate 7, which belongs to the protection scope of the invention.

[0095] The first link mechanism 100, the second link mechanism 200 and the third link mechanism 300 are located in the interlayer between the air inlet baffle 1, the air outlet baffle 2, the protective mesh cover 3 and the middle plate 7. Not only can they be driven by a motor 430 to move in sequence, but the link mechanism will not hinder the air flow. In addition, the bathroom heater also has multiple position states, so that the user can directly observe the working state of the bathroom heater:

[0096] In the off state, the air inlet baffle 1 and the air outlet baffle 2 are completely fitted with the shell 4, the air inlet 5 and the air outlet 6 are hidden inside the shell 4, and the shell 4 is in a sealed state.

[0097] When only the heating function is activated, or when both the heating and ventilation functions are activated:

[0098] The first stage is the stage of moving the air inlet baffle 1. The air inlet baffle 1 is also the main panel of the middle plate 7. The motor 430 drives the driving shaft 411 on the turntable 410 to rotate. The driving shaft 411 enters the slide slot 12 of the first driving member 110, driving the first driving member 110 and the connected first crank member 120 to rotate 180 degrees, so that the first crank member 120 drives the first sliding frame 142 to move horizontally on the first guide frame 141 through the first connecting rod 130. The first upper rotating shaft 161 that connects the first telescopic rod 152, the first top rod 160 and the air inlet baffle 1 is a pin. Since the first support 151 is fixed on the middle plate 7 of the middle plate 7, the air inlet baffle 1 is driven to rise through the first telescopic rod 152, and a gap is formed between the air inlet baffle 1 and the middle plate 7, and this gap is used as the air inlet 5.

[0099] In the second stage, the air outlet baffle 2 moves. The air outlet baffle 2 is also a small panel of the middle plate 7. The air outlet baffle 2 needs to be moved to the gap between the air inlet baffle 1 and the middle plate 7. Following the action of the previous step, the motor 430 continues to move, and the driving shaft 411 on the rotating disk 410 drives the second driving member 10 and the second crank member 220 to rotate 180 degrees, and pulls the second sliding frame to move horizontally through the second connecting rod member 230, driving the air outlet baffle 2 to slide into the gap between the middle plates 7 of the air inlet baffle 1.

[0100] The third stage is the moving stage of the protective net cover 3, which moves upward to be flush with the air inlet baffle 1. The motor 430 continues to operate, and the driving shaft 411 on the turntable 410 drives the third driving member 310 and the third crank member 320 to rotate 180 degrees, and the third sliding frame is pulled to move horizontally through the third connecting rod member 330. The third top rod 360 on the third sliding frame is connected to the protective net cover 3, and the protective net cover 3 is limited by the third telescopic rod 352 and cannot move horizontally, so that the protective net cover 3 can only move vertically to be flush with the air inlet baffle 1.

[0101] After completing the above three stages, the motor 430 will automatically shut down. When restarting, the motor 430 will reverse. The above steps are reversed in sequence to return to the sealed state.

[0102] When only the ventilation function is activated, only the first stage mentioned above is passed, and the air inlet baffle 1 is opened to enable the ventilation module 600 to work. If the air inlet baffle 1 is observed to be open, but the air outlet baffle 2 is not opened, it can be determined that the bathroom heater is in the ventilation mode. If the air inlet baffle 1 is observed to be open and the air outlet baffle 2 is also open, it can be determined that the bathroom heater is in the heating mode, or the heating mode and the ventilation mode are working at the same time.

[0103] The above content is a further detailed description of the invention in combination with specific preferred implementation methods, and it cannot be determined that the specific implementation of the invention is limited to these descriptions. For ordinary technicians in the technical field to which the invention belongs, several simple deductions or substitutions can be made without departing from the concept of the invention, which should be regarded as falling within the scope of protection of the invention.
