[0045] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0046] In winter, people often use heating devices to provide air for heating. For example, this heating device can be a hot air blower, which looks similar to a wall-mounted air conditioner, but only provides heating. Due to the heat conduction of air, when the air deflector 50 is opened downward, the hot air flows downward along the air deflector 50, enabling better heat exchange with the cold air in the room. Therefore, the air deflector 50 of the heating device is usually configured to open downward for air supply.

[0047] The air guide plate 50 of the existing hot air blower is relatively small in width, and the air is blown obliquely downward at the air outlet. The hot air flow cannot reach the ground after being blown out, and can only exchange heat with the cold air above the room. The temperature distribution in the room is uneven, users often feel cold feet, and the heating effect is poor.

[0048] The present disclosure provides a heating device, such as Figure 1 As shown, the air deflector 50 of this heating device is a "large-plate" type, with a relatively wide width, greater than or equal to 100 mm. Driven by the connecting rod assembly, the air deflector 50 can be extended out of the air outlet before opening downward, increasing the air supply range and distance. Upon reaching the air deflector 50, the hot air flow forms a jet that flows along the inner wall of the air deflector 50 toward the ground, providing close-fitting air supply and enhancing the heating efficiency of the heating device.

[0049] In some embodiments, the heating device includes the above-mentioned connecting rod assembly for the air guide plate 50, and also includes the air guide plate 50, and the connecting rod assemblies are respectively arranged at both ends of the air guide plate 50 to jointly drive the air guide plate 50 to open downward.

[0050] Optionally, the heating device includes a plurality of swing blades, which are vertically arranged at the air outlet of the heating device to swing the air left and right. In this way, the air supply range on both sides of the heating device is expanded, and the heating effect of the heating device is better improved.

[0051] Optionally, the heating device further comprises a driving element for providing driving force for the movement of the connecting rod assembly. In the embodiment of the present disclosure, a single driving element can drive the connecting rod assembly to cause the air guide plate 50 to extend and rotate.

[0052] In the embodiment of the present disclosure, the driving element may be a crank 10, such as Figure 10 shown.

[0053] Optionally, the crank includes a rotating disk 11 and a rotating rod 12, the rotating disk 11 has a rotation center, a first end of the rotating rod 12 is integrally connected to the rotating disk 11, and a second end of the rotating rod 12 is a free end.

[0054] Optionally, the crank is connected to a motor drive, and the drive shaft of the motor is arranged in a groove at the rotation center of the crank. The motor provides driving force for the rotation of the crank, thereby enabling the crank to be slidably connected to the first connecting rod 20 and drive the first connecting rod 20 to move.

[0055] Optionally, a transmission shaft 121 is disposed at the free end of the rotating rod 12. This allows the transmission shaft 121 to slide on the first connecting rod 20, thereby driving the first connecting rod 20 to move. It will be appreciated that the rotating disk 11 has a driving surface that contacts the motor, the rotating disk 11 and the rotating rod 12 have rotating surfaces that contact the first connecting rod 20, and the transmission shaft 121 is disposed on the rotating surface of the rotating rod 12.

[0056] The embodiment of the present disclosure also provides a connecting rod assembly for the above-mentioned air deflector 50, such as Figures 2 to 9 shown.

[0057] The structure and movement process of the connecting rod assembly will be introduced below by taking the connecting rod assembly on the right side of the air deflector 50 as an example.

[0058] In some embodiments, the connecting rod assembly for the air guide plate 50 includes a first connecting rod 20, a second connecting rod 30 and a track plate 40, one end of the first connecting rod 20 is rotatably connected to the air guide plate 50, and the first connecting rod 20 includes a first limiting portion; one end of the second connecting rod 30 is rotatably connected to the air guide plate 50, and the second connecting rod 30 includes a second limiting portion; the track plate 40 includes a first track and a second track, the first limiting portion is slidably set on the first track and the second track, and the second limiting portion is slidably set on the second track, and the track plate 40 is used to limit the movement trajectory of the first connecting rod 20 and the second connecting rod 30; wherein, the first track includes an arc-shaped track 42 extending in one direction, so that the first connecting rod 20 cooperates with the second connecting rod 30 under the drive of external force, so that the air guide plate 50 first moves horizontally out of the air outlet and then opens downward for attached air supply.

[0059] The motion mechanism provided by the embodiments of the present disclosure includes a first connecting rod 20, a second connecting rod 30, and a track plate 40. The track plate 40 is provided with a first track and a second track. The first limiting portion of the first connecting rod 20 is simultaneously matched with the first track and the second track, and the second limiting portion of the second connecting rod 30 is matched with the second track. The first track is provided with an arc track 42. In this way, the track plate 40 can limit the motion trajectories of the first connecting rod 20 and the second connecting rod 30, so that the first connecting rod 20 can drive the air deflector 50 to extend out of the air outlet and then open downward under the drive of an external acting force. The airflow blown out from the air outlet can form a jet flow when it reaches the air deflector 50 and blows towards the ground for attached air supply, so that the preset temperature can be reached in the room as soon as possible, improving the heating effect of the heating device. At the same time, the air supply range of the airflow blown out along the air deflector 50 is larger, so that the air volume per unit area is reduced and the air supply is more gentle, improving the comfort of users. Moreover, for the connecting rod assembly provided by the embodiments of the present disclosure, the first connecting rod 20 can realize the extension and rotation of the air deflector 50 under the action of an external acting force, simplifying the structure of the connecting rod assembly and achieving the effect of long-distance and large-range air supply.

[0060] Optionally, taking the perpendicular projection line of the straight line where the connection point of the first connecting rod 20 and the air deflector 50 extends along the extending direction of the air deflector 50 on the track plate 40 as the reference line, the starting end of the arc track 42 is arranged on the reference line, and the ending end of the arc track 42 is arranged on the upper side of the reference line.

[0061] As Figure 3 shown, the perpendicular projection line of the projection line of the straight line where the connection point of the first connecting rod 20 and the air deflector 50 extends along the extending direction of the air deflector 50 on the track plate 40 is AB, and AB is the above-mentioned reference line. Considering the reference line as a horizontal straight line, then, the ending end of the arc track 42 is located on the upper side of the reference line AB. That is, the shape of the arc track 42 is similar to the left stroke of the Chinese character "人" (person), and the arc track 42 extends from the reference line AB to the upper side of the reference line AB.

[0062] Optionally, the first track further includes a first straight track 41. The first straight track 41 is arranged in a straight line along the reference line and is connected to the starting end of the arc track 42. Among them, the first connecting rod 20 first moves along the first straight track 41 to drive the air deflector 50 to translate and extend out of the air outlet to a first preset position. After that, the first connecting rod 20 enters the starting end of the arc track 42 and moves along the arc track 42, and the second connecting rod 30 moves along the second track, thereby driving the air deflector 50 to open downward.

[0063] In the embodiments of the present disclosure, the first preset position is the position where the air deflector 50 translates and extends out of the air outlet and is about to start rotating, such as Figure 12As shown, at this time, there is a certain distance between the air deflector 50 and the air outlet, and the air deflector 50 can be opened upward at the first preset position. In the embodiment of the present disclosure, the rotation position of the air deflector 50 is not limited to the first preset position. The first preset position is the initial position of the rotation of the air deflector 50. The rotation of the air deflector 50 can be understood as extending and rotating at the same time.

[0064] In the embodiment of the present disclosure, the driving element provides driving force for the movement of the first link 20. Since the first link 20 and the second link 30 are both rotatably connected to the wind guide plate 50, the driving force is transmitted to the second link 30 through the first link 20, so that the second link 30 can also move linearly synchronously with the first link 20, and jointly drive the wind guide plate 50 to move horizontally and extend to the first preset position. After that, the first link 20 moves along the arc track 42, and the second link 30 continues to move along the linear track of the track plate 40. The first link 20 and the second link 30 generate relative movement, thereby driving the wind guide plate 50 to open downward.

[0065] Optionally, the first limiting portion includes at least two sliding posts. Optionally, sliding posts are provided in both the first track and the second track.

[0066] like Figure 7 As shown, the first limiting portion includes a first sliding post 25 and a second sliding post 26. The first sliding post 25 is disposed at the top of the first connecting rod 20, and the second sliding post 26 is disposed in the middle of the first connecting rod 20. The first sliding post 25 slides within the first track, while the second sliding post 26 slides within a linear track within the second track. When the first sliding post 25 moves from the first linear track 41 to the curved track 42, the second connecting rod 30 continues to move linearly along the second track. The first connecting rod 20 and the second connecting rod 30 generate relative motion, causing the first connecting rod 20 to change direction and cooperate with the second connecting rod 30 to drive the air deflector 50 downward.

[0067] Optionally, the second limiting portion includes at least two sliding posts, and the sliding posts are slidably arranged in the second track.

[0068] like Figure 8 As shown, the second limiting portion of the second connecting rod 30 includes a third sliding post 31, a fourth sliding post 32 and a fifth sliding post 33, which are arranged in a triangle. In this way, the limiting effect of the track plate 40 on the movement trajectory of the second connecting rod 30 is improved.

[0069] Optionally, the first straight track 41 includes a straight section and a transition section. The transition section is arranged at the connection point between the straight section and the curved track 42, and both sides of the transition section are arranged in an arc shape in the direction extending toward the curved track 42. The transition section is used to prevent the wind guide plate 50 from suddenly accelerating at the first preset position.

[0070] like Figure 3 As shown, Figure 3 The dashed lines in the figure indicate the straight segment and the transition segment, respectively. The starting segment of the first linear track 41 is the straight segment, and the portion of the first linear track 41 enclosed by the dashed line is the transition segment. If the first linear track 41 does not have a transition segment, the rotation speed of the air deflector 50 will suddenly accelerate at the first preset position. Visually, the air deflector 50 suddenly changes from a state of translational extension to a state of rapid rotation, which directly affects the user experience. After the first linear track 41 is provided with a transition segment, the air deflector 50 can gradually begin to rotate from the state of translational extension without sudden acceleration, thereby improving the degree of precise control over the movement of the air deflector 50.

[0071] Optionally, the proportion of time that the first connecting rod 20 moves along the first linear track 41 and the arc track 42 is greater than or equal to 0.5 and less than or equal to 0.7.

[0072] By limiting the ratio of the time the first sliding post 25 spends moving within the first linear track 41 and the curved track 42, the air deflector 50 can rotate at a moderate speed during its upward opening. Furthermore, the air deflector 50 can be extended a suitable distance before rotating, preventing it from contacting the heating device housing. For example, the ratio of the time the first sliding post 25 spends moving within the first linear track 41 and the curved track 42 can be 2:3, or 3:5, etc.

[0073] Optionally, the second track includes a plurality of parallel linear tracks, and the plurality of linear tracks are disposed on the lower side of the arc track 42 .

[0074] Optionally, the second track includes a second linear track 44, a third linear track 45 and a fourth linear track 46, the second linear track 44 is arranged along the direction in which the wind guide plate 50 extends and is located on the above-mentioned reference line with the first linear track 41; the third linear track 45 is arranged on one side of the second linear track 44; the fourth linear track 46 is arranged on the other side of the second linear track 44; wherein the second linear track 44, the third linear track 45 and the fourth linear track 46 are all located on the lower side of the first track.

[0075] Optionally, the second linear track 44, the third linear track 45, and the fourth linear track 46 are track grooves extending through the track plate 40. This allows the second sliding post 26 and the three sliding posts of the second stopper to slide securely within the track grooves, improving the stability of the connecting rod's movement within the track. Specifically, the third sliding post 31 moves within the second linear track 44, the fourth sliding post 32 moves within the third linear track 45, and the fifth sliding post 33 moves within the fourth linear track 46.

[0076] Optionally, the second connecting rod 30 is further provided with a through slide 35 that penetrates the plate surface of the second connecting rod 30. The provision of the through slide 35 on the second connecting rod 30 enables the second sliding post 26 of the first connecting rod 20 to pass through the through slide 35 and move along the second track.

[0077] Optionally, the first connecting rod 20 is provided with a through slot 21 , and the transmission shaft 121 of the crank 10 is slidably provided in the through slot 21 to provide a driving force for the first connecting rod 20 to move.

[0078] Optionally, the through slot 21 is linear, and the diameter of the circle formed by the movement of the transmission shaft 121 of the crank 10 is less than or equal to the length of the through slot 21. In this way, the transmission shaft 121 of the crank 10 can rotate 90° from the initial position in the first direction or the second direction and continue to rotate, and the rotation angle of the crank 10 is not limited by the length of the through slot 21.

[0079] Optionally, the first connecting rod 20 further includes a hollow area 22 , which is disposed above the through slot 21 , and a distance between an edge of the hollow area 22 and an outer edge of the first connecting rod 20 is greater than or equal to 0.5 mm.

[0080] like Figure 6 As shown, the hollow area 22 is provided above the through slot 21. The provision of the hollow area 22 reduces the weight of the first connecting rod 20, thereby reducing the torque of the motor when the motor drives the crank to drive the first connecting rod 20. At the same time, limiting the size of the hollow area 22 also ensures the reliability of the movement of the first connecting rod 20.

[0081] Optionally, the center of the circle where the arc track 42 is located is located on the lower side of the arc track 42, so that the air guide plate 50 rotates at a uniform speed during the process of opening downward.

[0082] In the embodiment of the present disclosure, Figure 3 The center of the circle where the arc track 42 is shown is located on the lower side of the arc track 42, that is, the shape of the arc track 42 is convex. In this way, the air guide plate 50 can rotate at a uniform speed during the downward opening process, avoiding the situation where the air guide plate 50 rotates downward quickly after extending out of the air outlet.

[0083] The present disclosure also provides another track plate 40, such as Figure 4 shown. Figure 3 and Figure 4 The curved tracks 42 in the two track plates 40 shown have different curvature directions. Figure 4 The arc track 42 shown is concave, that is, the center of the circle where the arc track 42 is located is located on the upper side of the arc track 42.

[0084] The two arc tracks 42 with different shapes cooperate with other components of the connecting rod assembly to drive the air guide plate 50 to move in different trajectories. The bending direction of the arc track 42 can affect the speed of the air guide plate 50 during the rotation process. Figure 3 The arc-shaped track 42 of the track plate 40 is shown to be convex, so that the air guide plate 50 can rotate at a constant speed after extending out of the air outlet. Figure 4 The arc-shaped track 42 of the track plate 40 shown is concave, so that the rotation speed of the air guide plate 50 will become faster and faster after extending out of the air outlet, and the air guide plate 50 will quickly open downward, directly affecting the user's sensory experience.

[0085] In order to more intuitively reflect the rotation speed of the air guide plate 50 after extending out of the air outlet, the embodiment of the present disclosure provides a schematic diagram comparing the rotation speed of the air guide plate 50 driven by the above two track plates 40. Figure 5 The rotation speed of the air guide plate 50 can be understood as the rotation angular velocity.

[0086] like Figure 5 As shown, the solid line in the figure is the Figure 3 The figure shows the time-dependent rotational speed of the air deflector 50 of the track plate 40. During the 0-2 second period, the air deflector 50's rotational speed is zero, indicating that the air deflector 50 does not rotate during its extension. During the 2-4 second period, the air deflector 50's rotational speed gradually increases, indicating that the air deflector 50 begins to rotate after extending from the air outlet. During the 4-10 second period, the air deflector 50's rotational speed remains constant, indicating that the air deflector 50 maintains a substantially constant speed during its rotation.

[0087] like Figure 5 As shown, the dotted line in the figure is the Figure 4 The figure shows the time-dependent rotational speed of the air deflector 50 of the track plate 40. During the 0-2 second period, the air deflector 50's rotational speed is zero, indicating that the air deflector 50 does not rotate during its extension. During the 2-4 second period, the air deflector 50's rotational speed gradually increases, indicating that the air deflector 50 begins to rotate after extending from the air outlet. During the 4-10 second period, the air deflector 50's rotational speed gradually increases, indicating that the air deflector 50 is rotating at an increasing speed.

[0088] Through the above Figure 5As shown, a comparison of simulation experimental data of the rotation speed of the air guide plate 50 using two types of track plates 40 is shown. From the rotation speed curve of the air guide plate 50 in the 4-10 second time period, it can be seen that the track plate 40 with a convex arc track 42 provided in the embodiment of the present disclosure can cooperate with other components of the connecting rod assembly to drive the air guide plate 50 to rotate at a uniform speed after extending out of the air outlet, thereby avoiding the phenomenon that the air guide plate 50 rotates faster and faster during the process, and improving the user's sensory experience.

[0089] Optionally, the curvature of the arc track 42 is greater than or equal to 10° and less than or equal to 25°. In this way, the air guide plate 50 can rotate at a constant speed to the maximum opening angle after extending out of the air outlet.

[0090] Optionally, a limiting mechanism is provided between the first connecting rod 20 and the second connecting rod 30 , and the limiting mechanism is used to prevent the second connecting rod 30 from shaking during the movement of the air guide plate 50 .

[0091] During the movement of the air deflector 50, only one end of the second connecting rod 30 is restrained by the air deflector 50. If the second connecting rod 30 is manually moved during the movement of the air deflector 50, the second connecting rod 30 will wobble up and down, which reduces the reliability of the second connecting rod 30. Furthermore, the up and down movement of the second connecting rod 30 will affect the normal movement of the air deflector 50, reducing the reliability of the entire movement mechanism.

[0092] Optionally, the limiting mechanism includes a limiting column 36 and a positioning groove 23, the limiting column 36 is arranged on the second connecting rod 30; the positioning groove 23 is inclined to the first connecting rod 20, and the limiting column 36 is slidably arranged in the positioning groove 23; wherein, in the process of the air guide plate 50 opening downward, the limiting column 36 slides in the positioning groove 23 to limit the position of the second connecting rod 30.

[0093] One end of the second connecting rod 30 is rotatably connected to the air deflector 50. The limiting post 36 of the second connecting rod 30 is disposed within the positioning slot 23. This provides two positioning points for the second connecting rod 30, thereby limiting the position of the second connecting rod 30. Regardless of the position of the air deflector 50, the limiting post 36 remains within the positioning slot 23, preventing the user from manually moving the second connecting rod 30, thereby improving the reliability of the second connecting rod 30.

[0094] Optionally, the second connecting rod 30 has a first plate surface opposite to the first connecting rod 20, and the limiting column 36 is provided on the first plate surface and located at the upper part of the second connecting rod 30, such as Figure 9 shown.

[0095] Optionally, the first connecting rod 20 has a limiting plate surface opposite to the second connecting rod 30 , and the positioning groove 23 is provided in the middle of the limiting plate surface.

[0096] When the air deflector 50 is in the closed state, the first connecting rod 20 and the second connecting rod 30 in the motion mechanism of the disclosed embodiment are in a partially abutted state. The second connecting rod 30 has a first plate surface opposite to the first connecting rod 20, and the first connecting rod 20 has a limiting plate surface opposite to the second connecting rod 30. The limiting post 36 is located at the upper part of the first plate surface of the second connecting rod 30, and the positioning groove 23 is located in the middle part of the limiting plate surface of the first connecting rod 20, that is, the middle and lower parts of the first connecting rod 20 are in abutment with the second connecting rod 30. Moreover, during the movement of the air deflector 50, the limiting post 36 is always in the positioning groove 23, and the upper end of the second connecting rod 30 is always kept in a limited state, thereby preventing the second connecting rod 30 from shaking.

[0097] Optionally, the upper edge of the positioning slot 23 is linear. When the air deflector 50 is closed, the limiting post 36 of the second connecting rod 30 is located at the lower end of the positioning slot 23. When the air deflector 50 is opened downward to its maximum angle, the limiting post 36 is located at the upper end of the positioning slot 23. It will be understood that the shape of the positioning slot 23 represents the changing trajectory of the contact point between the limiting post 36 of the second connecting rod 30 and the first connecting rod 20. This changing trajectory limits the upper end of the second connecting rod 30, preventing the user from manually moving the second connecting rod 30, thereby improving the reliability of the connecting rod assembly.

[0098] In the disclosed embodiment, the first connecting rod 20 and the second connecting rod 30 are both rotatably connected to the air guide plate 50 .

[0099] Optionally, a first connecting hole 27 is provided at one end of the first connecting rod 20 , and a second connecting hole 34 is provided at one end of the second connecting rod 30 .

[0100] Optionally, a connecting member 60 is provided between the first connecting rod 20, the second connecting rod 30 and the mounting seat 52 of the air deflector 50, and the connecting member 60 is hinged to the first connecting hole 27 and the second connecting hole 34 respectively, and the connecting member 60 is clamped with the mounting seat 52, as shown in FIG. Figure 12 shown.

[0101] Optionally, the connecting member 60 includes a connecting body 64, a first mounting portion 61, a second mounting portion 62 and a clamping portion 63. Figure 11 As shown, the first connecting hole 27 is hingedly connected to the first mounting portion 61, and the second connecting hole 34 is snap-fitted to the second mounting portion 62. Providing the connector 60 between the mounting base 52 of the air deflector 50 and the first and second connecting rods 20 and 30 facilitates assembly and disassembly of the air deflector 50, improving assembly efficiency.

[0102] The motion mode of the motion mechanism for the air deflector 50 provided in the embodiment of the present disclosure is as follows:

[0103] The initial state of the connecting rod assembly when the air guide plate 50 is in the closed state is as follows: Figure 2As shown. When the crank 10 rotates in the first direction, the transmission shaft 121 slides in the through slot 21 of the first connecting rod 20 to drive the first connecting rod 20 and the second connecting rod 30 to move. The first connecting rod 20 moves along the straight section of the first linear track 41, and the second connecting rod 30 moves along the second track, thereby driving the air deflector 50 to move linearly and extend to the first preset position. The first preset position can be understood as the position of the air deflector 50 corresponding to when the first sliding post 25 of the first connecting rod 20 moves to the end of the straight section, as shown in FIG. Figure 13 In the embodiment of the present disclosure, the first direction is based on Figure 13 Counterclockwise direction shown.

[0104] When the air guide plate 50 reaches the first preset position, the transmission shaft 121 continues to slide in the through groove 21, driving the first sliding post 25 of the first connecting rod 20 to enter the transition section of the first linear track 41 and move along the arc track 42, and the second sliding post 26 of the first connecting rod 20 continues to move in the second track. In this way, the first connecting rod 20 starts to move and turn, and the first connecting rod 20 and the second connecting rod 30 generate relative movement, thereby jointly driving the air guide plate 50 to open downward, meeting the air supply demand of the heating device, such as Figure 14 shown.
